Background
A known laryngeal mirror, such as that described in taiwan patent No. M243171, discloses a laryngeal mirror device 1 for use as an auxiliary guide in an artificial trachea cannula. The laryngeal mirror device 1 comprises a light emitting device 10 and a blade 20, wherein the blade 20 is in a meniscus shape and is provided with a tongue depressor part 21 which can be pressed into the mouth of a patient to increase the position of epiglottis, the tail end of the tongue depressor part 21 is provided with a light source rod 28, and a light source emitted by the light emitting device 10 can be led out by the light source rod 28 to generate a lamplight illumination effect, so that the intubation procedure can be more conveniently carried out.
The conventional laryngeal mask endotracheal tube is used to directly visually find the entrance of the trachea (glottis (glottis)) through the lips, mouth and throat of a patient in a direct visual manner, and is called direct or direct vision laryngeal mask (direct laryngoscope). If the deep structure in the throat of the patient cannot be clearly observed, the endotracheal tube cannot be inserted into the trachea of the patient in a critical extremely short time, and at this time, the safety of the patient is endangered by hypoxia. By difficult endotracheal intubation (difficult airway) is meant that a portion of the patient cannot see the entrance to the trachea (glottis) clearly for a variety of reasons, so that the endotracheal tube cannot be inserted correctly into the trachea or misplaced into the adjacent esophagus. If not resolved in time, the patient may quickly become hypoxic and even die. This condition occurs in patients with rough neck, swollen tongue, once-infected oropharynx, surgery, deformation, congenital structural abnormalities, or once-operated neck or radiation therapy. The patient's condition is rapidly worsened in a short period of time when difficult intubation occurs, and if not handled in time, the patient will quickly become anoxic and die, so the medical community needs to improve and develop better tracheal intubation equipment to overcome such extremely dangerous conditions. Accordingly, related industries have developed various image type laryngeal mirrors with image capturing and image displaying functions in response.
A laryngeal lens with image capturing/displaying has been developed, and as described in taiwan patent No. M427913, the image laryngeal lens set 05 includes a lens portion 10, an image display panel 20 and an arc-shaped combined lens portion 60. The image display panel 20 is combined with the first end 11 of the handle portion 10, the combined type mirror blade portion 60 is combined with the second end 12 of the handle portion 10, an image capturing device 92 and a light emitting member 93 are arranged at the front end of the combined type mirror blade portion 60, and when the tracheal intubation operation is performed, the image display panel 20 can display images captured by the image capturing device 92 in real time, so that a medical staff can adjust the angle position of the combined type mirror blade portion 60 pressed against the tongue of a patient in real time, and the tracheal intubation operation is performed smoothly.
However, the above-mentioned known image-type laryngeal lens set 05 has the following drawbacks:
First, the modular mirror blade portion 60 has only a single image capture device 92, which has an insufficient view angle, and because of the different internal configuration of each patient's mouth, the image capture device 92 sometimes cannot capture the tracheal position of the patient's throat quickly and effectively when the modular mirror blade portion 60 is pressed against the patient's tongue through the mouth cavity.
Secondly, even the combined type lens leaf portion 60 with different radian needs to be replaced temporarily, so that the image capturing device 92 can capture the tracheal position of the patient's throat. In this way, not only is the tracheal intubation delayed, but the secondary insertion of the modular leaflet 60 also causes secondary injury to the patient.
Third, because the image display panel 20 is combined with the first end 11 of the handle 10, when the medical staff pulls up the handle 10 forward, and further presses the combined type mirror blade 60 against the tongue of the patient, the image display panel 20 also changes the angle direction, so that the medical staff cannot smoothly see the image displayed by the image display panel 20 when performing the tracheal intubation, the smoothness of the intubation operation is affected by adjusting the angle again, and the time-consuming repeated adjustment is required to capture the visible and identifiable image because of the narrow viewing angle, which is very inconvenient.
Therefore, how to provide a laryngeal mirror can overcome the above-mentioned limitations of the conventional direct-view laryngeal mirror and the image-type laryngeal mirror, and make an operator effectively, rapidly and safely complete an extremely challenging and urgent tracheal intubation is an important issue. Pursuing patient safety, benefiting patients is a continuing and important goal for emergency and critical medicine.
Disclosure of Invention
In view of the above problems, the present invention aims to provide an image-type laryngeal mirror, which can overcome the problems that the view angle of the conventional image-type laryngeal mirror is not wide enough and the images of the laryngeal and glottic positions of a patient cannot be captured effectively, and which does not need to replace the blade of the laryngeal mirror tongue pressing piece with different curvatures, and avoid the defect of time-consuming repeated adjustment to capture visible and identifiable images, namely, the laryngeal and glottic positions of the patient can be observed in a wider view angle through a plurality of image capturing devices in real time at the same time, so that medical staff can perform the tracheal intubation rapidly, effectively shorten the intubation time and complete the extremely challenging and urgent tracheal intubation procedure once. The imaging device on the blade with the large angle (hyperangulated) at the front end of the design can capture glottic images which cannot be directly seen in extremely difficult intubation conditions, and solve the dilemma that long-term difficult intubation is difficult to overcome, namely, the tongue pressing piece blade is designed with larger curve radian, so that the multi-view image laryngeal mirror can be used for not only routine trachea intubation (routine endotracheal intubation) but also difficult intubation (difficult airway). Fifth, another potential danger of the traditional direct vision or image type laryngeal mirror is that when the trachea cannula starts to extend the blades into the oral cavity to prepare for exploring the glottis, the risk of injuring the tissues of the oral cavity and the throat still exists in the early blind period without direct vision or image assistance, and the front-end image capturing equipment can monitor the whole trachea cannula process from the beginning at all times, so that complications are avoided. Finally, a plurality of image capturing devices have one more survival opportunity, so that the masking of blood and sputum at one time is avoided, and meanwhile, the tracheal intubation is more effectively, rapidly and safely finished.
To achieve the above object, a multi-view image laryngeal mirror according to the present invention includes a grip, a tongue depressor blade, a first image capturing device, and a second image capturing device. The tongue depressor blade is detachably connected with the grab handle. The tongue depressor blade comprises a joint part, side plates and a transverse plate.

Various embodiments provided in accordance with the present invention will be described below with reference to the associated drawings, wherein like parts will be described with like reference numerals.
Referring to fig. 1A to 1D and fig. 2 at the same time, fig. 1A is a schematic perspective view of a multi-view image laryngeal mirror according to a first embodiment of the present invention. FIG. 1B is a schematic view of the multi-view image laryngeal mirror of FIG. 1A at another angle. Fig. 1C is an exploded view of the multi-view image laryngeal mirror shown in fig. 1B. FIG. 1D is a schematic view of the multi-view image laryngeal mirror of FIG. 1A at another angle. Fig. 2 is a schematic view showing the usage state of the multi-view image laryngeal mask of the present invention. In this embodiment, the multi-view image laryngeal mask 1 includes a grip 11, a tongue depressor blade 12, a first image capturing device 13, and a second image capturing device 14. The tongue depressor blade 12 is detachably connected with the grip 11. Tongue depressor blade 12 includes a joint 121, side plates 122, and cross plate 123. The coupling portion 121 is detachably coupled to one end of the grip 11. The side plate 122 extends outward from the joint 121. The cross plate 123 is folded and extended outward from one side of the side plate 122. For example, but not limited to, as shown in fig. 1A, the side plate 122 extends outward from the joint 121 in the X-axis direction, and the cross plate 123 extends outward from the upper side of the side plate 122 in the Z-axis direction.
The first image capturing device 13 is disposed on a side of the side plate 122 away from the transverse plate 123, and the first image capturing device 13 captures a first image P1. The second image capturing device 14 is disposed on the cross plate 123 and located at or adjacent to the central axis A1 of the cross plate 123, the second image capturing device 14 is far from the joint 121 than the first image capturing device 13, and the second image capturing device 14 captures the second image P2.
As shown in fig. 1A and 1B, the grip 11 is disposed along the Y-axis direction, the joint 121 of the tongue-pressing blade 12 is detachably connected to one end of the grip 11, and the side plate 122 extends outward (generally toward a direction away from the joint 121 and the grip 11, that is, generally toward the X-axis direction of fig. 1A and 1B) from the joint 121. The cross plate 123 extends outwardly from the side plate 122 (in a direction away from the side plate 122, i.e., in the Z-axis direction of fig. 1A). Here, a first angle between the transverse plate 123 and the side plate 122Such as but not limited to 45, 60, 75, 90 or 105 degrees, preferably a first angle between the cross plate 123 and the side plate 12290 Degrees (as shown in fig. 1D). In particular, as shown in fig. 1B, the cross plate 123 is provided in a warped shape from an end near the coupling portion 121 to an end far from the coupling portion 121, and the cross plate 123 has a warped angle θ, which may be, for example, but not limited to, 120, 135, 150 degrees, and is preferably 135 degrees. The tongue depressor blade 12 is designed with a large curve curvature, so that the multi-view imaging laryngeal mirror 1 can be used for not only routine intubation, but also difficult intubation (difficult airway). In addition, for example and without limitation, as shown in fig. 1A to 1D, the first image capturing device 13 is disposed at the bottommost portion of the side plate 122 (i.e. the bottommost portion of the side plate 122 in fig. 1B), and the second image capturing device 14 is disposed adjacent to one end of the transverse plate 123 far from the handle 11, and both can be used for capturing images at different angles, so as to achieve the effect of capturing images at multiple angles.
As shown in fig. 1B and 1C, the handle 11 may include a locking portion 111, and the tongue-pressing blade 12 may include a locking portion 124, which are configured to be disposed correspondingly to each other, so that the tongue-pressing blade 12 is detachably connected to the handle 11. In particular, the engaging portion 111 is taken as an example of the pivot and the engaging portion 124 is taken as an example of the hook, however, the engaging portion 111 and the engaging portion 124 may be a bump, a groove, or other engaging structures which are well known to those skilled in the art and can correspond to each other, so long as the engaging portion 111 and the engaging portion 124 can be detachably connected to each other, and the present invention is not limited thereto. In addition, during intubation, the tongue depressor blade 12 is used to press against the patient's tongue, and the end of the depressor blade 12 remote from the junction 121 and grip 11 (adjacent to the second image capture device 14) is used to raise the position of the epiglottis cartilage.
Referring to fig. 1A to 1D again, in the embodiment, the multi-view image laryngeal mirror 1 may further include a third image capturing device 15 disposed on a side of the transverse plate 123 away from the side plate 122, the third image capturing device 15 is far from the combining portion 121 than the first image capturing device 13, and the third image capturing device 15 captures a third image P3 adjacent to the combining portion 121 than the second image capturing device 14. As shown in fig. 1A and 1B, the third image capturing device 15 is farther from the joint 121 than the first image capturing device 13, and is closer to the joint 121 than the second image capturing device 14, that is, the first image capturing device 13, the third image capturing device 15 and the second image capturing device 14 are sequentially disposed from the joint 121 to the joint 121, the distances between the three image capturing devices 13-15 and the joint 121 are different (please refer to the X-axis), and the heights of the three image capturing devices are also different (please refer to the Y-axis) than the height of the handle 11. In addition, as shown in fig. 1D, the third image capturing device 15 is disposed on a side of the transverse plate 123 away from the side plate 122, and the three image capturing devices 13 to 15 are different from the handle 11 in distance from the Z axis, and the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 are sequentially disposed from the near to the far. Referring to fig. 1A to 1D together, the three image capturing devices 13 to 15 of the multi-view image laryngeal mirror 1 are disposed at different positions along the X, Y, Z axis, so that the first image P1, the second image P2 and the third image P3 with different view angles can be provided respectively, and the three images P1 to P3 can be partially overlapped or not overlapped with each other, so that the medical staff can more clearly see the position of the glottis during the subsequent intubation. In particular, when the multi-angle image laryngoscope 1 further includes the third image capturing device 15, the width of the cross plate 123 can be widened by 50% compared to the cross plate 123 of the multi-angle image laryngoscope 1 including only the first image capturing device 13 and the second image capturing device 14, so that the distance between the second image capturing device 14 and the third image capturing device 15 in the Z-axis direction is longer (please refer to fig. 1D), and the chance of mutual interference is reduced. In addition, in fig. 1D, the first image capturing device 13, the second image capturing device 14, and the third image capturing device 15 are positions whose arrangement is represented by circles, which are merely illustrative, and are not used to limit the shapes of the first image capturing device 13, the second image capturing device 14, and the third image capturing device 15.
Referring to fig. 1A and 1D, in the present embodiment, the tongue depressor blade 12 may further include a bottom plate 125 extending from the other side of the side plate 122 in an outward turning manner, for example, but not limited to, as shown in fig. 1A, the side plate 122 extends from the joint 121 in the X-axis direction, the bottom plate 125 extends from the lower side of the side plate 122 in the-Z-axis direction, and the bottom plate 125 and the cross plate 123 are disposed on two sides of the side plate 122 respectively. As shown in fig. 1A and 1D, the grip 11 is disposed along the Y-axis direction, and the side plate 122 extends outward (toward a direction away from the coupling portion 121 and the grip 11, that is, the X-axis direction of fig. 1A) from the coupling portion 121. The cross plate 123 and the bottom plate 125 extend outwards from the side plate 122 (in a direction away from the side plate 122, i.e., in the Z-axis direction in fig. 1D), so that the cross plate 123 and the bottom plate 125 are disposed at two ends and two sides of the side plate 122, respectively, and extend in different directions (Z-axis and-Z-axis directions) from the side plate 122, respectively. The cross plate 123 is disposed at an end of the side plate 122 adjacent to the handle 11, and the bottom plate 125 is disposed at an end of the side plate 122 remote from the handle 11. The provision of the base plate 125 allows the multi-view imaging laryngeal mask 1 to more easily move the patient's tongue during subsequent intubation. In addition, the second angle β between the bottom panel 125 and the side panel 122 is, for example, but not limited to, 45, 60, 75, 90, or 105 degrees, and preferably the second angle β between the bottom panel 125 and the side panel 122 is 90 degrees (as shown in fig. 1D).
Referring to fig. 1A again, in the present embodiment, the width of the bottom plate 125 gradually decreases from the position adjacent to the bonding portion 121 to the position far from the bonding portion 121. Specifically, the bottom plate 125 has a width W1 adjacent to the joint 121, a width W2 distant from the joint 121, the width W1 is greater than the width W2, and the width W2 may be reduced to zero adjacent to the end of the cross plate 123.
In the present embodiment, the width of the side plate 122 gradually decreases from adjacent to the joint 121 to far from the joint 121. Specifically, the width of the side plate 122 adjacent to the joint 121 is W3, the width away from the joint 121 is W4, the width W3 is greater than the width W4, and the width W4 may be reduced to zero adjacent to the end of the cross plate 123. The arrangement of the bottom plate 125 and the side plate 122 with gradually reduced widths from the position adjacent to the joint 121 to the position far from the joint 121 allows the multi-angle image laryngoscope 1 to more easily enter the oral cavity of a patient during intubation, and can improve the comfort of the patient.
Referring to fig. 1D again, in the present embodiment, the central axis A1 of the transverse plate 123 does not intersect with the axis A2 passing through the shaft center of the grip. That is, the tongue depressor blade 12 is disposed closer to the right of the drawing plane 1D than the axis A2 passing through the shaft center of the grip, and this arrangement facilitates the medical staff to put the multi-view image laryngeal mirror 1 into the mouth of the patient from the right side of the mouth of the patient when the patient lies down and the medical staff stands on the side of the head of the patient, and then move the multi-view image laryngeal mirror 1 toward the middle and left side of the mouth of the patient to press against the tongue of the patient. At this time, the open space (the intubation position of the endotracheal tube) between the lateral plate 123 and the side plate 122 is located at the middle of the oral cavity, so that the endotracheal intubation operation is performed. Fig. 1E further shows that the relative positions of the side plate 122 and the handle 11 can be changed according to the actual needs, so as to facilitate the tracheal intubation operation.
Referring to fig. 1C, in the multi-view image laryngeal mask 1 of the foregoing embodiment, the power supply device 112 may be disposed inside the handle 11, and the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 may be respectively electrically connected to the power supply device 112. The power supply 112 is, for example, but not limited to, a disposable battery or a rechargeable battery. The disposable battery is, for example, but not limited to, a carbon zinc battery, an alkaline manganese battery, a lithium battery, a zinc mercury battery, a magnesium manganese battery, or other disposable batteries known to those skilled in the art. Rechargeable batteries such as, but not limited to, lead acid batteries, nickel cadmium batteries, nickel hydrogen batteries, lithium ion batteries, or other rechargeable batteries known to those skilled in the art. Specifically, the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 may be electrically connected to the power supply 112 through a contact point C for opening or closing the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15, for example, the lines of the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 may be electrically connected along the side plate 122 or the cross plate 123 (for brevity and clarity of the drawing, the lines of the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 are not shown in the drawing) to the contact point C, and then electrically connected to the power supply 112 through the contact point C. In particular, when the power supply device 112 is a rechargeable battery, the multi-view image laryngoscope 1 may further comprise a wireless charging member (not shown), or the multi-view image laryngoscope 1 may further comprise a wired charging member (not shown) for assisting in charging the power supply device 112, and when the multi-view image laryngoscope 1 is provided with the wired charging member, the handle 11 is correspondingly provided with a charging hole for connecting with the mains power so as to assist in charging the power supply device 112, thereby improving the service time of the multi-view image laryngoscope 1.
In the foregoing embodiment, the first image capturing device 13, the second image capturing device 14, and the third image capturing device 15 may each have a light source and a photographic lens (not shown). Specifically, the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 integrate the light source and the photographic lens, so that the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 can simultaneously provide the light source and capture the image, and the medical staff can observe the light source provided by the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 directly from the oral cavity of the patient and also observe the images captured by the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15.
Referring to fig. 2, in the foregoing embodiment, the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 may be connected to the display D in a wireless transmission manner, so that the display D displays the first image P1, the second image P2 and/or the third image P3. According to the actual viewing requirement (such as but not limited to zooming in), the display D displays at least one image of the three images P1-P3.
The foregoing is a brief summary of the structure and shape of the present invention and presents the principles of efficacy and methods of use achieved by the present invention as follows:
Referring again to fig. 2, when the diaphragm 123 of the tongue depressor blade 12 of the present invention is pressed against the tongue 21 of the patient 2, the position of the epiglottis 22 can be raised, and at this time, the second image capturing device 14 is closer to the trachea 23 of the patient, and the first image capturing device 13 is farther from the trachea 23 of the patient and closer to the tongue tip 24 of the patient, so that the viewing angles of the first image capturing device 13 and the second image capturing device 14 are different, and the captured first image P1 and second image P2 partially overlap. The second image capturing device 14 is closer to the trachea 23 of the patient, so that the multi-view image laryngeal mirror 1 can observe the position of the tongue depressor blade 12 nearest to the patient after entering the oral cavity of the patient, and the blind intubation caused by the condition that the medical staff cannot clearly see the oral cavity of the patient is avoided, so that the tip of the tongue depressor blade 12 hurts the oral cavity or other internal tissues of the patient.
The display D of the present invention may display two divided pictures, one of which may display the first image P1 captured by the first image capturing device 13 and the other of which may display the second image P2 captured by the second image capturing device 14. Therefore, when the medical staff performs the intubation operation, the first image P1 and the second image P2 displayed by the remote display D can adjust the angle position of the diaphragm 123 against the tongue 21 of the patient in real time, so that after the first image capturing device 13 or the second image capturing device 14 captures the positions of the glottis 25 and the trachea 23 of the patient, the medical staff can smoothly insert the endotracheal tube into the trachea 23 of the patient through the glottis 25 via the diaphragm 123 and the side plate 122 when watching the images displayed by the display D, so as to complete the intubation process.
When the multi-view image laryngeal mask 1 of the present invention further includes a third image capturing device 15 disposed on a side of the transverse plate 123 away from the side plate 122, and electrically connected to the power supply device inside the grip 11. In the present embodiment, the third image capturing device 15 is far away from the joint 121 than the first image capturing device 13, and is close to the joint 121 than the second image capturing device 14. The third image capturing device 15 may capture the third image P3 and transmit the third image P3 to the display D in a wireless transmission manner, where the display D may display three split pictures for displaying the first image P1, the second image P2 and the third image P3 respectively. Therefore, the overall view angle of the present invention can be wider, and the medical staff can adjust the angular position of the transverse plate 123 against the tongue 21 of the patient in real time, so that the first image capturing device 13, the second image capturing device 14 or the third image capturing device 15 can quickly capture the positions of the glottis 25 and the trachea 23 of the patient, and the intubation operation can be smoothly performed.
In addition, the tongue pressing piece blade provided with a plurality of image capturing devices is detachably connected with one end of a grab handle of the multi-view image laryngeal mirror, and the tongue pressing piece blade comprises a combination part, a side plate, a transverse plate, a first image capturing device and a second image capturing device. Or the tongue depressor blade may further comprise a third image capturing device. Because the combination portion, the side plate, the cross plate, the first image capturing device, the second image capturing device and the third image capturing device are described in detail above, the description thereof is omitted.
In summary, the multi-view image laryngeal mask 1 of the present invention has the tongue depressor blade 12 with the first image capturing device 13 and the second image capturing device 14, and further has the third image capturing device 15, which can increase the view angle when the whole tongue depressor blade 12 presses against the tongue 21 of the patient, so that the patient can quickly capture the position of the glottis 25 and the trachea 23 of the laryngeal part of the patient even if the oral cavity structure of each patient is different when the medical staff performs the intubation operation, and the tongue depressor blade 12 with different curvature does not need to be replaced any more, so that the intubation operation is not delayed, further the hypoxia of the patient can be avoided, and the invention is suitable for general routine intubation and difficult intubation.
In addition, the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 of the present invention may be connected to the remote display D in a wireless transmission manner, so that the display D may display the first image P1, the second image P2 and the third image P3. Therefore, when the medical staff performs intubation, the patient can smoothly see the position of the glottis 25 and the trachea 23 of the throat of the patient displayed by the display D, and the intubation is very convenient, so that the smoothness during the intubation can be increased, and the intubation can be completed more quickly. Furthermore, the first image capturing device 13, the second image capturing device 14 and the third image capturing device 15 are arranged to avoid that the image capturing devices are simultaneously affected by sputum, blood clots, secretion or vomit of the patient, and when one of the image capturing devices is stained, the positions of the glottis 25 and the trachea 23 of the patient can be observed through the other image capturing devices, so as to avoid that the intubation process is affected.
The foregoing is by way of example only and is not intended as limiting. Any equivalent modifications or variations to the present invention without departing from the spirit and scope thereof are intended to be included within the scope of the following claims.
