Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pediatric anesthesia medical devices, and particularly relates to a foldable tracheal intubation positioning auxiliary device for pediatric anesthesia. BACKGROUND

[0002] During pediatric anesthesia, tracheal intubation is a key operation to ensure the patency of the airway of a child, maintain effective ventilation and oxygenation.

DETAILED DESCRIPTION

[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and are not used to limit the scope of the present application. In the following paragraphs, the present application is described in more detail by way of example with reference to the accompanying drawings. It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate, clearly assist the purpose of explaining the embodiments of the present application.

[0034] Please refer to Figures 1-10 In the embodiments of the present application, a foldable intubation positioning auxiliary device for pediatric anesthesia department includes an arc-shaped bite plate 7, and the side wall of the bite plate 7 is connected with a tongue depressor 3 through a rotating limiting device.

[0035] In an optional embodiment, the rotation limiting device includes two side plates 5. The two ends of the tongue depressor 3 are rotatably connected to the two side plates 5 via rotating shafts. A T-shaped support plate 4 is fixedly connected to the bottom side wall of the biting plate 7. The T-shaped support plate 4 has a horizontal through hole and a vertical through hole. A cylindrical groove 32 is formed on one end side wall of the tongue depressor 3. An insert rod 17 is slidably connected within the cylindrical groove 32. A first spring 14 is fixedly connected between one end of the insert rod 17 and the bottom side of the cylindrical groove 32. A strip groove 15 is formed on the side wall of the cylindrical groove 32. A pulling rod 16 is fixedly connected to the side wall of the insert rod 17. The pulling rod 16 is slidably connected within the strip groove 15, and one end of the pulling rod 16 extends out of the strip groove 15. It should be noted that when the device needs to be used, first pull the pulling rod 16 so that one end of the insert rod 17 enters the cylindrical groove 32, and then rotate the tongue depressor 3 so that the tongue depressor 3 and the biting plate 7 are perpendicular to each other. Figure 1 As shown, then release the pulling rod 16, and the insertion rod 17 will be inserted into the horizontal through hole on the T-shaped support plate 4 under the action of the first spring 14, so that the tongue depressor 3 is fixed. At this time, the device can be used to perform endotracheal intubation. When it is necessary to store it, similarly, the pulling rod 16 can be grasped and pulled so that one end of the insertion rod 17 enters the cylindrical groove 32, and then the tongue depressor 3 and the biting plate 7 are parallel to each other. Figure 10 As shown, when the pull rod 16 is released, one end of the insertion rod 17 is inserted into the vertical through hole. The foldable design makes the device easy to carry and store, and improves the utilization efficiency of medical resources.

[0036] The front end of the tongue depressor 3 is curved downwards. A piezoelectric ceramic sheet 1 is fixedly connected to the bottom side of the front end of the tongue depressor 3. The surfaces of the piezoelectric ceramic sheet 1 and the tongue depressor 3 are covered with medical-grade silicone (not shown). The flexible medical-grade silicone is used to reduce the pressure on the tongue surface. A through-hole insertion port 10 is opened in the middle of the biting plate 7. A rotating wheel 9 is rotatably connected inside the insertion port 10. A pressing block 11 is connected to one side of the insertion port 10 through an elastic pressing device. The elastic pressing device includes two sliding grooves 30. Two sliding grooves 30 are formed on the side wall of the endotracheal tube opening 10. Sliding rods 29 are slidably connected in both sliding grooves 30. A second spring 31 is fixedly connected between one end of each sliding rod 29 and the bottom side of the sliding groove 30. A pressing block 11 is fixedly connected to one end of the sliding rod 29. Under the action of the two second springs 31, the pressing block 11 will approach the rotating wheel 9. When the endotracheal tube is located between the rotating wheel 9 and the pressing block 11, the second springs 31 can elastically clamp the endotracheal tube between the rotating wheel 9 and the pressing block 11.

[0037] The pressure block 11 is located on the side of the rotating wheel 9. The surface of the rotating wheel 9 is provided with a silicone layer with anti-slip texture. The silicone layer with anti-slip texture can increase the friction when the endotracheal tube moves against the surface of the rotating wheel 9 to avoid slippage. A rotating rod 28 is vertically inserted through and fixedly connected to the center of the rotating wheel 9. The top of the rotating rod 28 is rotatably connected to the side wall of the tube opening 10 through a bearing.

[0038] The bite plate 7 has a disc cavity 6 inside. The bottom end of the rotating rod 28 extends into the disc cavity 6 and is fixedly connected to a disc 24. Both the disc 24 and the bite plate 7 are made of insulating material. The disc 24 is rotatably connected in the disc cavity 6. A second conductive ring 23 (inner diameter 15mm) and a first conductive ring 22 (inner diameter 10mm) are embedded and fixedly connected on the bottom side wall of the disc 24. Multiple second conductive plates 25 are fixedly connected to the inner side wall of the second conductive ring 23, and multiple first conductive plates 26 are fixedly connected to the outer side wall of the first conductive ring 22. A conductive sheet 26 and multiple second conductive sheets 25 are arranged alternately and sequentially (0.5 mm apart). A first electrode ring 19, a second electrode ring 20, and two conductive blocks 21 are fixedly connected to the bottom side wall of the disc cavity 6. The first electrode ring 19 abuts against the side wall of the first conductive ring 22, the second electrode ring 20 abuts against the side wall of the second conductive ring 23, and the two conductive blocks 21 abut against one of the first conductive sheets 26 and one of the second conductive sheets 25, respectively. A battery cavity 27 is provided inside the interlocking plate 7, and a 3V DC dry cell battery 18 is installed inside the battery cavity 27. Figure 9 As shown, the positive and negative poles of the DC dry cell 18 are electrically connected to the first electrode ring 19 and the second electrode ring 20 respectively via wires 33, and the two ends of the piezoelectric ceramic sheet 1 are electrically connected to the two conductive blocks 21 respectively via wires 33.

[0039] In an optional embodiment, the occlusal plate 7 has arc-shaped occlusal grooves on both the top and bottom sides, and a silicone sheet 8 is fixedly connected to the bottom side of each arc-shaped occlusal groove. The occlusal plate 7 is placed between the upper and lower teeth of the child, and the arc-shaped occlusal grooves and silicone sheet 8 can improve occlusal comfort.

[0040] In an optional embodiment, the front curved surface of the tongue depressor 3 is provided with two lights 2 and a transparent protective cover 12. A miniature camera 13 is provided inside the transparent protective cover 12. The camera 13 is electrically connected to an external display screen (not shown). When performing intubation, the two lights 2 can assist the camera 13 in taking pictures of the inside of the oral cavity. By observing the oral cavity picture taken by the camera 13, it is easier to control the speed and position of endotracheal intubation.

[0041] In an optional embodiment, the front end of the tongue depressor 3 is bent downward at an angle of 15°-20° to ensure that the front end naturally rests against the base of the tongue, reducing patient discomfort.

[0042] The working principle of this invention is:

[0043] When using it, first insert the tongue depressor 3 into the mouth and press it on the tongue until the curved front part of the tongue depressor 3 is close to the root of the tongue. Then, have the child open his mouth and place the occlusal plate 7 between the child's upper and lower teeth. The curved occlusal groove and silicone soft sheet 8 are used to improve comfort.

[0044] The endotracheal tube can then be inserted between the rotating wheel 9 and the pressure block 11. As the tube enters the oral cavity, it drives the rotating wheel 9 to rotate. The rotation of the rotating wheel 9, in turn, drives the disc 24 to rotate via the rotating rod 28. The second conductive ring 23 and the first conductive ring 22 on the bottom side of the disc 24 are electrically connected to the second electrode ring 20 and the first electrode ring 19, respectively. Since the second electrode ring 20 and the first electrode ring 19 are connected to the positive and negative electrodes of the DC dry cell battery 18, the multiple second conductive plates 25 on the sidewall of the second conductive ring 23 and the multiple first conductive plates 26 on the sidewall of the first conductive ring 22 carry positive and negative charges, respectively. When the disc 24 rotates, the staggered second conductive plates 25 and first conductive plates 26 will pass sequentially through the two conductive blocks 21, causing... The charges on the two conductive blocks 21 are repeatedly changed, forming an effect similar to alternating current. This alternating current is applied to both ends of the piezoelectric ceramic plate 1 through the wire 33, causing the piezoelectric ceramic plate 1 to vibrate at a low intensity (in actual experiments, the cannula is inserted at a rate of 1 cm per second, and the vibration frequency of the piezoelectric ceramic plate 1 is 20-30 Hz). The low intensity vibration of the piezoelectric ceramic plate 1 can stimulate the contraction of the tongue root muscles in obese children. The contraction of the tongue root muscles can pull the tongue root backward, expand the pharyngeal cavity space, reduce the pressure on the glottis, and thus promote the natural opening of the glottis. This invention uses a gentle physical stimulation method to promote the natural opening of the glottis. Afterwards, the doctor can control the cannula to be accurately inserted into the glottis according to the position of the glottis captured by the observation camera 13, thus completing the cannula insertion operation.

[0045] If the stimulation generated by the vibration frequency of the piezoelectric ceramic plate 1 is low and the glottis does not open completely, the insertion tube can be controlled to move back and forth near the glottis. By driving the rotating wheel 9 to rotate faster, the vibration frequency of the piezoelectric ceramic plate 1 can be increased, thus prompting the glottis to open.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
