Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an airway tracheal intubation device. Background Art

[0002] The airway endotracheal intubation device is a key device used in the medical field to ensure that the patient's airway is unobstructed, especially in anesthesia or emergency situations. When the patient's natural breathing is suppressed or unable to breathe effectively, the device mechanically inserts the endotracheal tube into the trachea to ensure smooth air flow, thereby protecting the patient's life safety;

[0003] Currently, the most common method is to insert a catheter into the patient's mouth and connect the catheter to the trachea near the throat of the patient's airway. Since the patient's mouth and the trachea in the patient's throat are in a perpendicular position to each other, most of the prior art uses a hose for intubation. After the hose is inserted into the mouth, the hose needs to be bent downward 90° just above the trachea in the throat to facilitate the insertion of the hose into the trachea in the throat. However, due to the uncertainty of the bending position of the hose, intubation often faces the risk that the bent hose may tilt or deviate from the trachea, thereby causing difficulty in intubation. Therefore, there is a problem in the prior art that it is difficult to control the bending position of the hose when the hose is inserted into the patient's throat, resulting in difficulty in intubation. Summary of the invention

[0004] In view of the deficiencies of the prior art, the purpose of the present invention is to provide an airway tracheal intubation device, which solves the problem in the prior art that it is difficult to control the bending position of the hose when inserting it into the patient's throat, resulting in difficulty in intubation.

[0013] One end of the counterweight extends out of the hose, and a circular air bag is fixed on the outer peripheral wall of the end of the counterweight;

[0014] An air pump is fixed on the peripheral wall of one end of the inner liner tube located outside the mask, and a connecting tube is arranged inside the inner liner tube. One end of the connecting tube passes through the peripheral wall of the inner liner tube and is connected to the output end of the air pump, and the other end of the connecting tube passes through the second round through hole and is fixedly connected to the annular airbag. The connecting tube is connected to the inside of the annular airbag, and the length of the connecting tube is greater than the distance between the annular airbag and the air pump. When the annular airbag is not inflated, the diameter of the outer peripheral wall of the annular airbag is smaller than the diameter of the outer peripheral wall of the hose.

[0015] The clamping assembly includes a pair of clamping blocks arranged on the inner side of the mask, the two clamping blocks are symmetrically arranged about the central axis of the first circular through hole, and the ends of the two clamping blocks close to each other are provided with semi-cylindrical grooves arranged coaxially with the first circular through hole, and the diameter of the semi-cylindrical groove is larger than the diameter of the outer wall of the inner liner tube, and the diameter of the semi-cylindrical groove is smaller than the diameter of the outer wall of the hose.

[0018] Beneficial effects of the present invention:

[0019] 1. The purpose of facilitating intubation of the trachea in the airway and throat of the patient is achieved by the coordinated arrangement of the inner liner tube, the hose and the counterweight block, and the position of the bending part of the hose is effectively controlled. The sliding of the hose along the inner liner tube facilitates the control of the drooping insertion depth of the hose, thereby improving the accuracy and safety of the intubation process and solving the problem in the prior art that it is difficult to control the bending part of the hose when the hose is inserted into the throat of the patient, which causes difficulty in intubation;

[0022] 2. Through the setting of the camera, it is convenient to take real-time photos of the relative position of the end of the hose close to the counterweight block and the patient's trachea, and then adjust the depth of the inner liner tube extending into the patient's mouth, so as to push the inner liner tube to control and adjust the bending part of the hose;

[0023] 3. By setting the second round through hole, the inner liner tube and the inside of the hose can always be kept unobstructed, avoiding the liner tube from being blocked due to the bending of the hose;

[0024] 4. Through the coordinated arrangement of the annular airbag, the air pump and the connecting tube, when the hose is inserted into the trachea to the desired position, the annular airbag can be inflated. After the annular airbag expands, its peripheral wall is closely attached to the inner wall of the patient's trachea, thereby achieving a stable connection between the hose and the patient's trachea.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, an airway endotracheal intubation device includes a mask 100 for wearing on the patient's face, at least one elastic strap 101 is fixed to the mask 100, and both ends of the elastic strap 101 are fixed to the mask 100;

[0033] The mask 100 is provided with a first round through hole 102 horizontally facing the patient's oral cavity, the side of the mask 100 close to the patient's face along the axis direction of the first round through hole 102 is set as the inner side of the mask 100, and the side of the mask 100 away from the patient's face is set as the outer side of the mask 100;

[0034] The airway endotracheal intubation device also includes an inner liner tube 200 placed coaxially with the first round through hole 102, the inner liner tube 200 is made of a hard material, both ends of the inner liner tube 200 are open, and one end of the inner liner tube 200 passes through the first round through hole 102 and extends to the inside of the mask 100;

[0035] A hose 300 with openings at both ends is sleeved on the outer peripheral wall of the inner liner tube 200, the end of the inner liner tube 200 located inside the mask 100 is located inside the hose 300, and the end of the inner liner tube 200 located outside the mask 100 is located outside the hose 300, the outer wall diameter of the inner liner tube 200 is equal to the inner wall diameter of the hose 300, and the outer wall of the inner liner tube 200 is smooth and slidably connected to the hose 300, the diameter of the first round through hole 102 is larger than the outer wall diameter of the hose 300, and a circular ring-shaped counterweight 400 is coaxially fixed on the inner peripheral wall of the hose 300 away from the inner liner tube 200 end, and the end of the hose 300 away from the counterweight 400 is located outside the mask 100;

[0036] A clamping assembly is provided on the inner wall of the mask 100, and the clamping assembly is used to clamp and fix the portion of the inner liner tube 200 where the hose 300 is sleeved;

[0037] The device is used in conjunction with a ventilator in the corresponding technology. After the intubation is completed, the end of the inner liner tube 200 located outside the mask 100 is used to connect the ventilator. When in use, the patient wears the mask 100 on the face through the elastic strap 101, and makes the end of the hose 300 close to the counterweight 400 extend out of the inner liner tube 200. Under the action of the weight of the counterweight 400 and the hose 300 themselves, the part of the hose 300 extending out of the inner liner tube 200 naturally droops, and then the medical staff pinches the end of the hose 300 away from the counterweight 400 and the inner liner tube 200, and pushes the inner liner tube 2 00 and the hose 300 are synchronously extended into the patient's oral cavity, so that one end of the hose 300 fixing the counterweight 400 moves to the top of the patient's throat trachea, at this time, the inner liner tube 200 is stopped, and then the hose 300 is pushed along the inner liner tube 200 to move to the inside of the mask 100, and under the pull of the counterweight 400, the end of the hose 300 close to the counterweight 400 continuously moves downward, and finally the end of the hose 300 close to the counterweight 400 moves downward to be inserted into the patient's trachea, and finally the hose 300 and the inner liner tube 200 are clamped and fixed by the clamping assembly to complete the intubation work;

[0038] The inner liner tube 200, the hose 300 and the counterweight 400 are arranged in coordination to facilitate intubation of the trachea in the pharynx of the patient, and the position of the bending portion of the hose 300 is effectively controlled. The hose 300 slides along the inner liner tube 200 to facilitate control of the insertion depth of the hose 300, thereby improving the accuracy and safety of the intubation process and solving the problem in the prior art that it is difficult to control the bending portion of the hose 300 when the hose 300 is inserted into the throat of the patient, thus causing difficulty in intubation.

[0039] The inner liner tube 200 and the hose 300 after the intubation are clamped and fixed by the clamping assembly, without manual holding, which reduces the risk of the inner liner tube 200 and the hose 300 slipping after the intubation is completed, and improves the stability of the connection between the hose 300 and the patient's trachea;

[0040] In the prior art, when a single hose 300 is used for intubation, it is necessary to ensure that the patient's upper and lower jaws are always in an open state to avoid clogging of the hose 300 when closing; while in the present application, a hose 300 is sleeved on the outside of a hard inner liner tube 200. Under the action of the hard hose 300, the patient's upper and lower jaws can be kept in an open state, and the hose 300 on the outside of the inner liner tube 200 can improve the comfort of the patient during use.

[0041] A camera 500 is fixedly mounted on the counterweight 400; the camera 500 is used to take real-time photos of the relative position between the end of the hose 300 close to the counterweight 400 and the patient's trachea, and then adjust the depth of the inner liner 200 extending into the patient's oral cavity, so as to facilitate the inner liner 200 to control and adjust the bending part of the hose 300;

[0042] Preferably, the camera 500 in the present device can be a camera 500 with Bluetooth function, which can be connected to an external computer or other equipment via Bluetooth so that the captured image can be transmitted in real time. If a Bluetooth camera 500 is used, there is no need to lay a data cable for transmitting data in the inner lining tube 200 and the hose 300.

[0043] After the hose 300 bends downward, the upper peripheral wall of the bent portion of the hose 300 sags and contacts with the side of the inner liner tube 200 located on the inner side of the mask 100. The upper peripheral wall of the bent portion of the hose 300 is likely to cause a seal blockage to the inner liner tube 200, thereby affecting the patient's air intake or exhaust. In order to solve this problem, a second circular through hole 201 is provided on the lower peripheral wall of the inner side of the mask 100 of the inner liner tube 200; when the hose 300 sags vertically near the end of the counterweight 400, the second circular through hole 201 is connected to the inside of the hose 300. After the hose 300 is bent and blocks the end of the inner liner tube 200 near the inner side of the mask 100, the provision of the second circular through hole 201 can continue to maintain the conduction between the inner liner tube 200 and the hose 300, thereby avoiding affecting the patient's air intake or exhaust.

[0044] In order to improve the stability of the connection between the hose 300 and the patient's trachea, one end of the counterweight block 400 extends out of the hose 300, and a circular airbag 600 is fixed on the outer peripheral wall of the end of the counterweight block 400;

[0045] An air pump 601 is fixed on the peripheral wall of one end of the inner liner tube 200 located on the outside of the mask 100, and a connecting tube 602 is arranged inside the inner liner tube 200. One end of the connecting tube 602 passes through the peripheral wall of the inner liner tube 200 and is connected to the output end of the air pump 601, and the other end of the connecting tube 602 passes through the second round through hole 201 and is fixedly connected to the annular airbag 600. The connecting tube 602 is connected to the inside of the annular airbag 600, and the length of the connecting tube 602 is greater than the distance between the annular airbag 600 and the air pump 601. When the annular airbag 600 is not inflated, the diameter of the outer peripheral wall of the annular airbag 600 is smaller than the diameter of the outer peripheral wall of the hose 300.

[0046] When the hose 300 is inserted to the required position of the trachea, the air pump 601 is turned on, and the air pump 601 inflates the annular airbag 600 through the connecting tube 602. The annular airbag 600 expands so that its peripheral wall is in close contact with the inner wall of the patient's trachea, thereby achieving a stable connection between the hose 300 and the patient's trachea; when the hose 300 needs to be removed, the gas in the annular airbag 600 is discharged through the air pump 601, and the annular airbag can be used in the deflated state.

[0047] In order to facilitate the clamping and fixing of the hose 300 and the inner liner tube 200, the clamping assembly includes a pair of clamping blocks 700 arranged on the inner side of the mask 100, and the two clamping blocks 700 are symmetrically placed about the central axis of the first circular through hole 102. The two clamping blocks 700 are close to each other. The ends are provided with semi-cylindrical grooves coaxially placed with the first circular through hole 102, and the diameter of the semi-cylindrical groove is larger than the diameter of the outer wall of the inner liner tube 200, and the diameter of the semi-cylindrical groove is smaller than the diameter of the outer wall of the hose 300. When the clamping blocks 700 are fitted together, they can be spliced ​​to form a circular hole coaxially placed with the first circular through hole 102. A driving part is provided on the inner side of the mask 100 to drive the two clamping blocks 700 to move closer to or away from each other. The driving part drives the two clamping blocks 700 to move closer to each other, so that the two clamping blocks 700 squeeze and compress the peripheral wall of the hose 300, thereby clamping and fixing the hose 300 and the inner liner tube 200. After squeezing and compressing the hose 300, it is ensured that the clamping position of the hose 300 and the inner liner tube 200 has good sealing performance.

[0048] The driving part includes a screw rod 701 and a slide rod 702 vertically arranged on the inner side of the mask 100. The upper and lower ends of the slide rod 702 are respectively fixed to the cover wall of the upper and lower end surfaces of the inner side of the mask 100. The clamping blocks 700 are slidably mounted on the slide rod 702. The clamping blocks 700 are all mounted on the screw rod 701 and threadedly connected thereto. The screw threads of the screw rod 701 on both sides of the symmetry plane of the two clamping blocks 700 have opposite spiral directions. The upper and lower ends of the screw rod 701 are both round rods with smooth peripheral walls. The upper and lower ends of the screw rod 701 are respectively rotatably connected to the cover wall of the upper and lower end surfaces of the inner side of the mask 100. The lower end of the screw rod 701 passes through the mask 100 and is fixedly mounted with a turntable 703. The peripheral wall of the turntable 703 is provided with anti-slip grooves. By rotating the turntable 703, the screw rod 701 is driven to rotate. The screw 701 drives the two clamping blocks 700 to transmit the thread, and the two clamping blocks 700 are controlled and adjusted to move closer or farther from each other by controlling the rotation direction of the screw 701.

[0049] In order to ensure smooth relative sliding between the hose 300 and the end of the liner tube 200 located on the inner side of the mask 100, the end tube wall of the liner tube 200 located on the inner end of the hose 300 is in the shape of a raised arc surface; this can prevent the end of the liner tube 200 located on the inner side of the mask 100 from interfering with the sliding of the hose 300, thereby ensuring the smoothness of the relative sliding process.
