The pressure display can read the direction according to the scale design, and can be installed positively or can be installed reversely.
As shown in fig. 2, the pressurizing bag body 1 includes a pressurizingbag air bag 11, a pressurizing bag hanging tube 12 is arranged at the top of the pressurizingbag air bag 11, aninfusion bag hook 14 is arranged at the lower end of the pressurizing bag hanging tube 12, ahook film 13 is arranged on the side surface of the lower part of theinfusion bag hook 14 for fixing, an infusionbag wrapping layer 15 is arranged on the back surface of the pressurizingbag air bag 11, and afirst inflating nozzle 16 is arranged at the center position of the lower end of the pressurizingbag air bag 11.
The pressurizingbag airbag 11 is made of high-strength nylon TPU composite fabric, so that the pressurizing bag airbag has good air tightness and durability, and the fabric is selected and can be defined to be used for one time or repeatedly used for many times. The pressing bag hanging pipe 12 is made of a high-strength TPU pipe or a nylon material, and the pressing bag hanging pipe 12 is sewn and then wrapped with a plurality of layers of mesh cloth to bear the pressure of at least 6 KG. Thehook coating film 13 is fixed on the air bag through a high-frequency process and is used for fixing theinfusion bag hook 14.Infusion bag couple 14 adopts PC high strength material, but at least bearing weight 6 KG. Theinfusion wrapping layer 15 of the pressurizing bag adopts a TPU film or high-strength mesh cloth, has good transparency, and can monitor the liquid amount in the infusion bag at any time. The TPU film is generally made of a material with a bright surface and a frosted surface, the bright surface is outward to increase the transmittance, and the frosted surface is inward to reduce the viscosity between the bag and the film when the blood bag or the infusion bag is filled. The inflatingnozzle 16 at the lower part of the pressurizing bag adopts a joint line-free design, and air leakage is avoided when the inflating nozzle is connected with a pipe.
As shown in fig. 8, theproduct pressure display 7 includes apiston rod 17, a main bodyair relief groove 18, a pressure display main body 19, apiston bowl 20, a pistonbowl plug head 21, asecond inflation nozzle 22, athird inflation nozzle 23 and acompression spring 24, wherein thepiston rod 17 is provided with acorresponding scale mark 27, and thescale mark 27 is distinguished by colors; thepiston rod 17 is connected with apiston bowl 20, thepiston bowl 20 is connected with a pistonbowl plug head 21, acompression spring 24 is sleeved outside thepiston rod 17, and thesecond inflation nozzle 22 and thethird inflation nozzle 23 are connected with a pressure display main body 19; the pressure display body 19 is connected with a cover 26; the main bodyair leakage groove 18 is arranged on the side wall of the pressure display main body 19.
The pressuredisplay piston rod 17 is externally provided with ascale mark 27 which is divided into three stages of 150mmHg (20 Kpa), 250mmHg (33 Kpa) and 300mmHg (40 mmHg), and can also be divided into two stages of 150mmHg (20 Kpa) and 300mmHg (40 Kpa). Each of the blocks is marked with a different color, such as white/green/red, or yellow/green/red. Thepiston bowl 20 is made of a high-elasticity material and is good in air tightness. Thepiston bowl plug 21 is used for reinforcing the connection between thepiston bowl 20 and thepiston rod 17, so that thepiston bowl 20 cannot fall off during operation. The two ends of thesecond inflating nozzle 22 and thethird inflating nozzle 23 are combined without joint lines, and are connected with the pipe without air leakage. The cover 26 is provided with fixingholes 25 for fixing thepressure display 7 to the second air tube 6. The pressure display body 19 is designed with abody vent groove 18, and when the pressure is over-pressurized, the product can automatically release air.
When the pressurizing bag is pressurized, the bottom of the pressure display cavity is pressurized to compress thecompression spring 24, thepiston rod 17 extends out, the larger the pressure is, the more thepiston rod 17 extends out, and thescale 27 on the piston rod displays the current air pressure. Meanwhile, thepiston bowl 20 is extruded by air pressure and is attached to the inner wall of the pressure display main body 19, so that the sealing effect is achieved, and even if thepiston rod 17 moves, thepiston bowl 20 can still achieve the sealing effect.
When the pressure of the pressurizing bag exceeds the maximum safe pressure, thepiston bowl 20 can touch the main bodyair leakage groove 18 which is arranged in advance on the upper portion of the pressure display main body 19, sealing fails, air in the pressure display main body 19 is rapidly discharged from the air leakage groove, the pressure in the main body 19 is reduced, and thepiston rod 17 retracts until thepiston bowl 20 leaves the air leakage groove and contacts a sealing area without the air leakage groove on the lower portion of the pressure display main body 19. At this time, the pressure in the pressurizing bag is stabilized at about 300 mmHg. When the pressurized bag is deflated, the pressure decreases, thespring 24 extends, thepiston rod 24 retracts, and the piston rodouter scale 27 displays the real-time pressure.
The specific application method of the utility model is as follows:
(1) the plasma bag or the transfusion bag is arranged in the interlayer of the transfusion pressurizing bag air bag and the back membrane, the hanging rope of the plasma bag or the transfusion bag is hung on the hook of the transfusion pressurizing bag, then the hanging pipe of the pressurizing bag is hung on the transfusion fixing frame, and the pressurizing transfusion bag can be used in a flat way.
(2) After the whole set of product is assembled, the ball is pinched by hands to inflate, and the air flows into the air bag of the transfusion pressurization bag through the three-way valve, the air pipe, the pressure display and the like.
(3) The infusion quantity can be automatically adjusted by adjusting the pressure of the air bag of the pressurizing bag.
(4) When the infusion pressurizing bag is used, the pressure display can display the current air pressure, and if the pressure in the bag exceeds the maximum safe air pressure, the pressure display can automatically deflate.
(5) After the transfusion is finished, the three-way valve is opened to deflate, and the pressurizing bag air bag can be squeezed by hands to accelerate the exhaust. Or the luer connector is unscrewed, and the air is directly and quickly exhausted.
(6) If the transfusion is continued, the above operation is repeated.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
