Theleft display area 1321 and theright display area 1321 may be seamlessly butted or may be disposed at a certain distance.

In this embodiment, thedisplay area 1321 is substantially in the shape of a long bar, and since the originalphysical keys 120 are reduced and the flat shape of thesyringe pump 100 with a width larger than a height is fully utilized, the area of thedisplay area 1321 is greatly increased, so that more information can be displayed and the user can conveniently check the information.

Further, in thesyringe pump 100 of the other embodiments, the width of thedisplay area 1321 of thescreen assembly 132 is greater than or equal to 70% of the width of the front surface of thepump door 130. Since thesyringe pump 100 is generally wider than it is tall, the space in the width direction of thesyringe pump 100 is sufficient to form anelongated display area 1321 that is larger than thedisplay area 1321 of the existing product. And then guarantee thatdisplay area 1321 is bigger, the show of more information of reality can be convenient for the user to look over. The width is a distance between the left and right sides of thesyringe pump 100 in a normal use state.

In some embodiments, at least one of the small screens can be selected as a common display screen for displaying information only, and at least one of the small screens can be selected as a touch display screen capable of displaying information and realizing touch control functions, so that the display and touch control functions can be completed under the combination of the small screens. For example, some small screens can be used as the real-time display area 1321b, and some small screens can be used as thetouch area 1321 a.

Further, referring to fig. 23-26, in one embodiment, thescreen assembly 132 includes anouter panel 1322, atouch screen 1323 and adisplay screen 1324, wherein theouter panel 1322 has atransparent area 1322a and anopaque area 1322b disposed around thetransparent area 1322 a. Theouter panel 1322 may be formed from clear glass, plastic, or other material. The display area of thedisplay 1324 is exposed through thetransparent area 1322a for displaying related information. Theopaque region 1322b has anupper region 1322b-1, alower region 1322b-2, afirst side region 1322b-3, and asecond side region 1322b-4, thefirst side region 1322b-3 and thesecond side region 1322b-4 being located between theupper region 1322b-1 and thelower region 1322 b-2. Theopaque region 1322b is generally square shaped, but may have other shapes, such as circular or irregular. Usually, thedisplay 1324 is correspondingly provided with a display control chip (hidden in the figure and not shown), and thetouch panel 1323 is correspondingly provided with a touch control chip (hidden in the figure and not shown). In a typical display panel, a plurality of display control chips are provided for transmitting and receiving signals, respectively. Because the number of the display control chips is large, and the touch control chips are added, it is difficult to find a place on the pump door to put all the chips down. Therefore, in a general syringe pump, the display control chip and the touch control chip are mounted on the upper side or the lower side of the back surface of thedoor 131. In order to avoid exposing the control chips, theopaque regions 1322b need to be shielded, which results in the upper andlower regions 1322b-1 and 1322b-2 of theopaque regions 1322b being wider, and generally the width of theupper region 1322b-1 or thelower region 1322b-2 is difficult to be less than 40 mm. In addition, thesyringe pump 100 itself is not high, so that thedisplay area 1321 of thescreen assembly 132 is further compressed in the height direction, which is not favorable for displaying information.

In contrast, in this embodiment, the transmitting end and the receiving end of thedisplay 1324 are integrated on one display control chip, which reduces the number of display control chips and reduces the assembly space required by the display control chips and the touch control chips. Further, referring to fig. 24, the display control chip and the touch control chip are disposed on the back of thefirst side area 1322 b-3. Thefirst side region 1322b-3 may be the left side or the right side of theouter panel 1322.

This configuration may allow for the upper 1322b-1, lower 1322b-2, andsecond side 1322b-4 regions of theopaque region 1322b of theouter panel 1322 to be reduced in width (e.g., dimension in the direction indicated by B, C, D in fig. 3) as desired, thereby allowing thedisplay area 1321 of theouter panel 1322 to be larger without changing the size of theouter panel 1322, which may also be larger for thecorresponding display 1324, and increasing the area of thedisplay area 1321.

Thus, thedisplay area 1321 of thescreen assembly 132 can be as close to the outer edge of theopaque area 1322b as possible on the upper and lower sides, and a narrow bezel effect can be achieved. This configuration takes full advantage of the width of thepump door 130, allowing thedisplay area 1321 of thescreen assembly 132 to be further raised in height dimension without changing the volume of thepump door 130. Based on this structure, in one embodiment, the width of theopaque region 1322b in the region where the control chip is not disposed, for example, the width of theupper region 1322b-1, thelower region 1322b-2 and thesecond side region 1322b-4, may be set to be 2-4mm, for example, 3.3mm, at the minimum.

Further, in one embodiment, a screen test interface is disposed on the back side of thefirst side 1322b-3, and the screen test interface is connected to the display control chip and the touch control chip. The display control chip, the touch control chip and the screen test interface are arranged on the same side, so that the wire outgoing is facilitated, the space of the unilateral screen test interface can be smaller than 12mm, and the occupied space of the unilateral screen test interface is preferably reduced by 6 mm. Meanwhile, thenon-display area 1321 above and below theopaque area 1322b occupies the smallest space, so that the upper and lower sides of theopaque area 1322b are extremely narrow and can be less than 40 mm.

The embodiment uses a single integrated chip, adopts a mode of integrating a driving end and a receiving end, and places the side edge. In addition, the test interface is arranged on one side in the embodiment, and the width of the test interface is set to be less than 12 mm. Based on the structure, by adopting the scheme shown in the above embodiment, thedisplay 1324 can generally adopt a COG process with lower cost, that is, a chip on glass process, which can reduce the cost and meet the requirement of coordination of a narrow frame and the whole.

Referring to fig. 24, in an embodiment, to further reduce the space of the control chip, the interface of thedisplay 1324 and the interface of thetouch screen 1323 are integrated into anintegrated interface 1325.

The display control chip has aninterface cable 1325a, the touch control chip has aninterface cable 1325b, and the two interface cables are integrated on anintegrated interface 1325 integrating display and touch control, so that the respective interfaces do not need to be separately arranged.

In order not to encroach too much on the space of thefirst side wall 1322b-3, referring to fig. 24, in one embodiment, theintegrated interface 1325 is disposed along the length of thedisplay 1324 from thefirst side wall 1322b-3 to the middle of thedisplay 1324. In this way, theintegrated interface 1325 can be located on the back of thedisplay 1324 without extending beyond the perimeter of thedisplay 1324 to avoid increasing the width of the other sides of theopaque region 1322 b.

In one embodiment, thedisplay area 1321 is 7 inches in size so that more information can be displayed for viewing by the user.

In one embodiment, in the case of anenlarged display area 1321, to ensure display quality, the screen resolution of thedisplay 1324 is not less than 960 × 272 in one embodiment.

To take full advantage of the greater width and length of the pump door, in one embodiment, the length of thedisplay area 1321 is greater than 5 times its width, for example, the ratio of length to width is 6: 1.

Referring to fig. 6-7, 11-14 and 16, in some embodiments, thephysical key 120 is disposed on the front surface of thepump door 130, and is located above, below, beside or integrated on thescreen element 132. Thephysical keys 120 integrated with thescreen component 132 can also be disposed above, below or on the sides of thescreen component 132.

With continued reference to fig. 1 and 3, the present embodiment further arranges some or all of thephysical keys 120 on a side portion (key hole 1322b-5 shown in the figure, i.e., a second side region) of theouter panel 1322 opposite to thecontrol chip 1324. In the layout, thecontrol chip 1324 and the physical keys 120 (thekey holes 1322b-5 are shown in the figure) are respectively arranged on two sides of thescreen 1323, the layout is relatively fixed, the requirements of man-machine operation are better met, the narrow frame design of theupper side region 1322b-1 and thelower side region 1322b-2 of thescreen assembly 132 can be realized, thedisplay region 1321 is enlarged, thewhole screen assembly 132 and thephysical keys 120 can be integrally coordinated, and the ergonomic habit of a user is met.

In a typical touch display screen, the screen itself is made of glass, and it is complicated to add thephysical keys 120 to the screen. Therefore, the keys of the touch display screen generally use the touch function, add sound and light, and vibrate to improve the sensitivity of the client of the keys, but the feeling given to the client by this method cannot reach the effect of thephysical keys 120, and meanwhile, the reliability is not reliable than thephysical keys 120, and the recognizability is not strong than thephysical keys 120. Thephysical keys 120 of some non-touch display screens are difficult to realize that liquid or dirt does not remain on the keys, and although the problem of liquid residue can be solved by a surface pasting mode, the transparent effect of glass is difficult to achieve in the aspect of appearance, and the effect of the touch display screen cannot be achieved.

Further, referring to fig. 5-7, thephysical key 120 includes akey switch 126 connected to the control unit, akey cap 124 covering thekey switch 126, and a supportingframe 125 supported inside thekey cap 124. Thekey switch 126 is located on the inside of theouter panel 1322.Keycap 124 extends partially from the inside ofouter panel 1322 throughkey hole 1322b-5 for depression by a user. The keycap and the key switch can be movably contacted or disconnected according to the pressure on the keycap. Thesupport skeleton 125 secures thekey cap 124 within thekey hole 1322 b-5. Thekeycap 124 is in sealing fit with the opening wall of thekey hole 1322b-5, and the waterproof and dustproof effects are achieved.

In one embodiment, referring to fig. 27, one end of the supportingframe 125 abuts against theframe 1311 of thedoor 131, and the other end abuts against thekey cap 124, so that thekey cap 124 is in a suspended state. Thesupport frame 125 is configured for easy assembly and easy manufacture, and can be used to conveniently secure thekeycap 124 to theouter panel 1322 of thescreen assembly 132.

Of course, in some embodiments, the supportingframe 125 can be omitted, and thekeycap 124 can be directly fixedly connected to theouter panel 1322 or the door 131 (e.g., theframe 1311 or the supporting beam 1312) by other means, such as welding, clamping or other fixing means, so as to be fixed in the opening wall of thekey hole 1322 b-5.

Further, referring to fig. 25-27, thekey cap 124 has apressing portion 1241 and a mountingportion 1243 bent from the outer periphery of thepressing portion 1241, the mountingportion 1243 is located between thedoor 131 and thescreen assembly 132, and can be clamped by the door 131 (specifically, the middle portion of the frame 1311) and the screen assembly 132 (specifically, the outer panel 1322), so as to prevent thekey cap 124 from being displaced. Of course, thekey cap 124 may be in a relaxed state between the door 131 (specifically, the frame 1311) and the screen assembly 132 (specifically, the outer panel 1322). One surface of thepressing portion 1241 facing thekey switch 126 is provided with aconvex abutting block 1242, the abuttingblock 1242 can be separated from thekey switch 126 or transmitted without force under normal conditions, and when thekey cap 124 is pressed down, the abuttingblock 1242 can abut against thekey switch 126 to trigger thekey switch 126.

Thekey cap 124 can be made of elastic materials, preferably elastic flexible materials, so as to improve the pressing hand feeling. In one embodiment, the supportingframework 125 tightly supports the inner wall of thekey cap 124, so that thekey cap 124 is tightly fitted to the opening wall of thekey hole 1322b-5 to achieve a sealed connection. Of course, in some embodiments, thekeycap 124 and theouter panel 1322 can be hermetically connected by a sealing member and/or an adhesive.

The design can integrate theentity key 120 with thescreen component 132 or the outer cover, particularly, theentity key 120 is integrated on thescreen component 132 under the condition of not damaging the screen, so that the hand feeling of theentity key 120 is met on the basis of ensuring that the screen effect is not influenced, liquid can be prevented from entering the screen, the screen is convenient to clean, and the requirement of frequently disinfecting and cleaning medical instruments is met. In addition, because existing infusion pumps and/or syringe pumps are often used in multiple pieces, and because of space constraints, it is common to place the infusion pump and/or syringe pump in multiple stacks, or even multiple stacks, in a mounting rack; in this regard, the infusion pump and/or the syringe pump are typically exposed only on the front side. In the scheme, theentity keys 120 and thescreen component 132 are integrated into a whole and are arranged on the front surface of the infusion pump, so that the pressing operation of a user can be facilitated, and particularly, medical personnel can conveniently operate the keys of the infusion pump on the front surface of the infusion pump under the medical emergency condition.

In one embodiment, the shortest distance from thetransparent area 1322a of theouter panel 1322 to the wall of thekey hole 1322b-5 is 2-4mm, so that the area of thetransparent area 1322a can be enlarged as much as possible without changing the size of theouter panel 1322, so as to expose more display areas of thedisplay 1324.

In one embodiment, the outer surface of thepressing portion 1241 of thekey cap 124 is flush with the outer surface of theouter panel 1322, so that the outer surface of thescreen assembly 132 maintains a good flatness, and thescreen assembly 132 and thesolid keys 120 are integrally formed as a single plane, which is simple and elegant, and is also convenient for cleaning.

Of course, thesyringe pump 100 shown in fig. 1 and 2 is merely exemplary, and in other embodiments, thescreen assembly 132 and thephysical keys 120 may be disposed on thepump body 110. Alternatively, in some embodiments, thesyringe pump 100 may not have thepump door 130, and theentire syringe pump 100 is a unitary structure similar to thepump body 110, and thescreen assembly 132 and thephysical keys 120 may be disposed on the unitary structure.

Outer panel 1322

Based on the inventive concept, the embodiment of the application also provides an infusion pump. Unlike thesyringe pump 100 described above, the infusion pump is configured to drive the infusion tube to deliver the infusion fluid for a set time and flow rate.

In one embodiment, referring to fig. 28 and 29, the infusion pump includes apump body 210, a drive device, a control unit,physical keys 220, and apump door 230. Wherein the driving device and the control unit are not shown in the figure.

Thepump body 210 has aplacement position 211 for placing the infusion tube, and also has a liquid stopping structure (not shown) for installing the infusion tube and cutting off the infusion tube during the non-working period to prevent the liquid in the infusion tube from excessively entering the patient. Under the normal transfusion state, the liquid in the transfusion tube can freely flow. When thepump door 230 is opened, the liquid stop clamp clamps the infusion tube to stop the flow of liquid. The liquid stopping structure is linked with thepump door 230, the cut-off state of the liquid stopping structure to the infusion tube is controlled by the movement of thepump door 230, for example, the liquid stopping structure is driven to cut off the infusion tube when thepump door 230 is opened, the liquid stopping structure can release the infusion tube when thepump door 230 is closed, the infusion tube can still be in the state of cutting off the infusion tube, and the timing of cutting off the infusion tube by the liquid stopping structure is controlled by the control unit. The liquid stopping structure includes but is not limited to a clamping structure such as a liquid stopping clamp. The driving device is used for liquid flowing in the infusion tube. Wherein, the driving device can adopt a peristaltic pump or other devices which can drive the liquid in the transfusion tube to move. The peristaltic pump may include a motor and corresponding peristaltic mechanism.

The control unit is used for controlling the driving device. The control unit may include a processor and a peripheral interface. The processor may be used to send instructions to the drive. The peripheral device interface can be connected with peripheral devices such as theentity key 220 and the like for signal transmission, so that the processor can control the driving device according to the wishes of a user.

The control unit is electrically connected tophysical keys 220 for a user to input commands. Theentity key 220 includes at least one of a power key, an emergency stop key, a main menu key, a screen unlocking key and a pump door unlocking key. Thephysical keys 220 may control the processor through a bus and peripheral interfaces. The specific power supply key is used for being connected with the control unit, and the control unit is driven to send a control signal to the power supply system by pressing the power supply key so as to realize power supply and power off of the injection pump. The specific emergency stop key is used for being connected with the control unit, and the control unit is driven to send a control signal to the driving device by pressing the emergency stop key so as to realize the movement or stop of the driving device of the injection pump. The specific main menu key is used for being connected with the control unit, and the control unit is driven to send a control signal to the display screen control chip by pressing the main menu key, so that an infusion main interface is displayed on the display screen. The specific screen unlocking key is used for being connected with the control unit, and the control unit is driven by the screen unlocking key to send a control signal to the touch screen control chip, so that a preset touch function or a preset touch area is opened/closed on the touch screen. The pump door unlocking key is used for being connected with the control unit, and the pump door unlocking key is pressed to drive the control unit to send a control signal to the pump door switching mechanism so as to open or close the pump door. Generally, a user sets the flow rate and the volume of medicine and liquid required by a patient according to medical orders through a human-computer interface of an infusion pump, an infusion set which can be matched for use is selected according to the brand and specification of the infusion set indicated by the infusion pump, and a control system of the infusion pump automatically converts the flow rate and the flow data into the operation parameters of a driving motor according to preset infusion set characteristic parameters. The driving motor drives the cam shaft of the peristaltic mechanism to rotate through the speed reducing mechanism, the cam shaft rotates to drive a group of pump blades to do linear reciprocating motion, the pump blade group and the extrusion plate are matched to extrude and release the outer wall of the infusion apparatus in a reciprocating mode in sequence, and liquid in the infusion apparatus is driven to flow continuously and directionally, so that the purpose of constant-speed and quantitative infusion is achieved.

Thepump door 230 is movably mounted on thepump body 210 to cover and uncover the infusion tube mounted on thepump body 210, so as to prevent the infusion pump from being touched by foreign objects during operation and affecting the injection operation. Referring to fig. 28 and 29, thedoor 230 is rotatably mounted to thepump body 210, and this rotation is achieved by a hinge. In addition, thepump door 230 may be mounted in other movable manners, such as sliding or folding. When thepump door 230 is opened in a foldable manner, thescreen assembly 132 may also be provided in a foldable manner, if desired.

Thepump door 230 includes adoor body 231 and ascreen assembly 232. Thescreen component 232 is connected to the control unit (specifically, a processor) so as to be controlled by the control unit to display specified information, and meanwhile, can input instructions and information to the control unit in a touch manner. Thescreen element 232 has adisplay area 2321 capable of displaying information, wherein at least a part of thedisplay area 2321 has a touch function, that is, at least a part of the area of thescreen element 232 is a touch display screen, which can be connected to a control unit, and can both display information and receive a touch instruction of a user. The non-touch area of thedisplay area 2321 may be used for display only, and a common display screen may be adopted.

At least a part of thedisplay region 2321 of thescreen component 232 has a touch function, so that someentity keys 220 for inputting instructions can be omitted, for example, onlyimportant power keys 221 andemergency stop keys 222 are reserved, and thus, thedisplay region 2321 can be ensured to be larger, more information can be displayed, and the user can conveniently view the information.

Referring to fig. 28-30, in one embodiment, the side of thedoor 231 facing the user is the front of thepump door 230. Thescreen assembly 232 is disposed on the front surface of thepump door 230, thedisplay region 2321 of thescreen assembly 232 extends from the left side of the center line of the front surface of thepump door 230 to the right side of the center line, and the width of thedisplay region 2321 of thescreen assembly 232 is greater than the height thereof. As shown in fig. 30, thedisplay area 2321 may extend from the left side of the center line of the front surface of thepump door 230 to the right side of the center line, or may be divided into a left display area and a right display area, where the left display area is located at the left side of the center line, and the right display area is located at the right side of the center line. The left display area and the right display area can be in seamless butt joint, and can also be arranged at a certain distance.

In this embodiment, thedisplay region 2321 is substantially in the shape of a long bar, and since the originalphysical keys 220 are reduced and the flat shape of the infusion pump with the width larger than the height is fully utilized, the area of thedisplay region 2321 is greatly increased, so that more information can be displayed and the user can conveniently check the information.

Further, referring to fig. 30, in another embodiment of the infusion pump, the width of thedisplay area 2321 of thescreen assembly 232 is greater than or equal to 70% of the width of the front surface of thepump door 230. Since the width of the infusion pump is generally larger than the height, the space in the width direction of the infusion pump can be fully filled, and therefore anelongated display area 2321 larger than thedisplay area 2321 of the existing product is formed. Further, thedisplay area 2321 is ensured to be larger, so that more information can be displayed, and the user can conveniently check the information. Wherein, the width refers to the distance between the left side and the right side of the infusion pump in the normal use state. The height is the distance between the top side and the bottom side in the vertical direction in the normal use state of the infusion pump.

Of course, in an embodiment, the width of thedisplay area 2321 of thescreen component 232 may be greater than or equal to 70% of the width of the front surface of thepump door 230, and thedisplay area 2321 may extend from the left side of the center line of the front surface of thepump door 230 to the right side of the center line as a whole, so as to further increase the size of thedisplay area 2321 of thescreen component 232.

Of course, the infusion pump may also include other components, such as a plunger pump drive system, a storage system, a sensory monitoring system, an alarm system, etc., which are not further described herein.

Further, referring to fig. 30, in one embodiment, the height of thedisplay area 2321 of thescreen assembly 232 is greater than or equal to 60% of the height of the front surface of thepump door 230. Therefore, the occupation ratio of thedisplay area 2321 on the front surface of thepump door 230 can be further improved, more information can be displayed, and more personalized setting and display can be conveniently performed according to the needs of the user.

In one embodiment, a portion of thedisplay area 2321 of thescreen component 232 has a touch function, and information or instructions input by a user through a touch manner are displayed on thedisplay area 2321 in real time. Referring to fig. 4 and 5 (although fig. 4 and 5 show thesyringe pump 100, the distribution of thedisplay area 1321 can also be applied to an infusion pump, the structure of thedisplay area 1321 is the structure of thedisplay area 2321 of thescreen element 232 in the present embodiment), the portion with the touch function is referred to as atouch area 1321a, and the non-touch area in thedisplay area 2321 is referred to as a real-time display area 1321 b. Information and instructions input by the user in thetouch area 1321a may be displayed in thedisplay area 2321 in real time, which includes displaying in the entire display area 2321 (including thetouch area 1321a itself), and also includes displaying only in the real-time display area 1321 b. The real-time display area 1321b and thetouch area 1321a may be implemented by a wholelarge screen 1323 in a partitioned manner, or may be implemented by different small screens.

Preferably, in one embodiment, the area of thedisplay region 2321 of thescreen assembly 232 is greater than or equal to 2/3 of the area of the front face of thepump door 230. In this way, a larger area of thedisplay region 2321 and thetouch region 1321a (a portion of thedisplay region 2321 having a touch function) may be provided.

In another embodiment, theentire display region 2321 of thescreen element 232 is a touch display screen with both information display and touch functions. The touch display screen can be realized by various screen assemblies which can realize information display and touch functions. The whole touch display screen can be used as atouch area 1321a, so that more information can be displayed, the operation of a user is facilitated, and the use convenience is greatly improved.

Referring to fig. 31-39, in one embodiment, thescreen assembly 232 is located below the front of thepump door 230. The left or right portion of thescreen assembly 232 extends upward to enlarge the area of thescreen assembly 232. When thescreen assembly 232 is raised upward, as shown in fig. 31-33, the raised portion is spaced from theframe 1322 of thedoor 231. Alternatively, as shown in fig. 34-39, the raised portion may extend to therim 1322 of thedoor body 231.

Of course, in other embodiments, thescreen assembly 232 is located below the front of thepump door 230. At this time, the left or right portion of thescreen assembly 232 extends downward, enlarging the area of thescreen assembly 232.

Further, as shown in fig. 30-33, 35, 40, and 42-44, in some embodiments, awarning light 240 is included, thewarning light 240 being disposed above, below, to the side of, or integrated with thescreen assembly 232. In fig. 31-33, 35, thewarning light 240 is integrated into a raised portion of the left portion of thescreen assembly 232. In addition, the warninglamp 240 may be integrated on a boss portion protruded on the right portion of thescreen assembly 232. In fig. 30, 31, 40, and 43-44, the warninglamp 240 is disposed at a position of arim 1322 of thedoor body 231, above thescreen assembly 232. In fig. 42, the warninglamp 240 is integrated on the left side of thescreen assembly 232. Of course, thewarning light 240 may be disposed at other positions of thepump door 230 and thepump body 210, which is not illustrated herein.

Thescreen element 232 may have a large screen (e.g., an integral touch screen), and in one embodiment, thescreen element 232 may have at least two separate small screens (see fig. 21 and 22). In fig. 21, thescreen assembly 232 has two separatesmall screens 132a, 132 b. In fig. 22, thescreen assembly 232 has three separatesmall screens 132a, 132b, 132 c.

In some embodiments, at least one of the small screens can be selected as a common display screen for displaying information only, and at least one of the small screens can be selected as a touch display screen capable of displaying information and realizing touch control functions, so that the display and touch control functions can be completed under the combination of the small screens. For example, some small screens can be used as the real-time display area 1321b, and some small screens can be used as thetouch area 1321 a.

In order to further increase the area of thedisplay region 2321 in thescreen element 232, in an embodiment, thescreen element 232 adopts the same structure as thescreen element 132, specifically please refer to the structure shown in fig. 23 and 24 and the above description, so as to obtain thescreen element 232 with extremely narrow widths at the upper and lower sides.

In other examples, the infusion pump may havephysical keys 220, and thephysical keys 220 may be anemergency stop key 222, a pump door unlock key 223, amenu key 224, etc. in addition to apower key 221. Thesephysical keys 220 may be provided on thepump door 230 or on thepump body 210.

Referring to fig. 28, 30-45, in some embodiments, thephysical button 220 is disposed on the front surface of thepump door 230, above, below, to the side of, or integrated with thescreen element 232. Thephysical keys 220 integrated with thescreen assembly 232 may also be disposed above, below, or to the side of thescreen assembly 232.

In one embodiment, some or all of thephysical keys 220 are disposed on thescreen assembly 232. In particular, thephysical keys 220 are mounted on an outer panel (as previously described) of thescreen assembly 232.

In a typical touch display screen, the screen itself is made of glass, and it is complicated to add thephysical keys 220 on the screen. Therefore, the keys of the touch display screen generally use a touch function, add sound and light, and vibrate to improve the sensitivity of the client of the keys, but the sensitivity of the client cannot achieve the effect of thephysical keys 220, and meanwhile, the reliability is not reliable than that of thephysical keys 220, and the identifiability is not strong than that of thephysical keys 220. Thephysical keys 220 of some non-touch display screens are difficult to realize that liquid or dirt does not remain on the keys, and although the problem of liquid residue can be solved by a surface pasting mode, the transparent effect of glass is difficult to achieve in the aspect of appearance, and the effect of the touch display screen cannot be achieved.
