Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a difficult intubation type multi-functional tracheal catheter. Background Art

[0002] A tracheal catheter is a medical device that is inserted into a patient's trachea and / or bronchus to create a temporary artificial respiration channel for the patient, especially for patients who cannot breathe independently. Common intubation heads have one or two cuffs. After the cuffs are inflated, they can play a role in fixing the intubation and sealing the airway. It can also be without a cuff. The catheter body is usually made of a polymer material, and a wire coil is buried inside the catheter body to improve the radial strength and axial softness. Some catheter bodies adopt anti-laser materials or multiple layers to resist laser irradiation. It is an intubation for inserting into the patient's trachea through the nose / mouth or percutaneously. One end is connected to an anesthesia ventilator through a breathing pipeline to maintain the patient's breathing.

[0003] During the use of most existing tracheal catheters, when adding medicine to the patient, it is necessary to disconnect the connection between the tracheal catheter and the external device, which not only destroys the airtightness of the airway, but also may cause external bacteria to enter the patient's body along with the medicine solution, affecting the patient's body. Therefore, it is necessary to install a local anesthetic atomization pipeline inside the tracheal catheter to administer medicine to the patient, avoiding the operation of repeatedly opening the connection between the tracheal catheter and the ventilator in the prior art, maintaining the airtightness of the tracheal catheter, and effectively reducing the probability of cross-infection.

[0004] However, during the use of the tracheal catheter, since the local anesthetic atomization pipeline is generally fixedly installed during installation, the spraying angle of the local anesthetic atomization pipeline inside the tracheal catheter cannot be adjusted, and the pressure of the local anesthetic atomization pipeline cannot be changed. Therefore, during the administration of the local anesthetic atomization pipeline, it can only continuously administer medicine to the same position, and the spraying distance of the local anesthetic atomization pipeline cannot be changed. As a result, when spraying deep into the trachea with the local anesthetic atomization pipeline, it is necessary to insert the tracheal catheter deeper, causing discomfort to the patient.

[0005] Therefore, the present invention provides a difficult intubation type multi-functional tracheal catheter to solve the above problems. Summary of the Invention

[0020] (III) Beneficial effects

[0021] Through the mutual cooperation of structures such as the drug delivery mechanism, the ventilation mechanism, and the aspiration injection mechanism, after the tracheal catheter is inserted into the patient's body, an anesthetic is applied to the patient through the drug delivery mechanism, high-frequency jet ventilation is performed on the patient through the ventilation mechanism, a drug is injected into the patient and substances generated inside the patient's trachea are aspirated through the aspiration injection mechanism, and the fiber optic lens is inserted into the patient's body and controlled through the visual and operable fiber optic lens insertion port to observe the patient's body, thereby achieving the multi-functional effect of the tracheal catheter. And since the catheter body is of an enhanced steel wire spiral structure, the flexibility and plasticity of the catheter are increased, facilitating manipulation and shaping in difficult airways, so that the tracheal catheter can be used in difficult airways;

[0022] Through the setting of the drug delivery mechanism, when it is necessary to spray the anesthetic at different positions, the non-standard motor is started, so that the two driving gears mesh and rotate, causing the threaded cylinder to drive the threaded rod to move up and down, causing the clamping plate to drive a part of the drug delivery tube to move, and through the setting of the rotating shaft, the angle of one end of the drug delivery tube is adjusted, so that the drug delivery tube can spray at different positions;

[0023] When it is necessary to spray the anesthetic deep in the patient's trachea, the electric push rod is started, so that the electric push rod drives the rotating plate to rotate inside the corresponding hollow tube, and one side of the lower surface of the rotating plate presses the drug delivery tube. Through the mutual cooperation of the pressing blocks, the diameter of the drug delivery tube is reduced, thereby increasing the spraying pressure of the anesthetic, so that the anesthetic can be sprayed deep in the trachea;

[0024] Through the setting of structures such as the ventilation mechanism, when the gas passes through the corresponding hollow tube at high frequency, the gas enters the interior of the connecting block and the conical block, and is sprayed at different positions of the trachea through the air duct, avoiding the continuous spraying of the gas on a certain point of the trachea and causing discomfort or harm to the trachea.

[0044] Installation rings 24 fixedly connected to the corresponding hollow tube 3 are fixedly connected to the surfaces of the aspiration tube 21 and the injection tube 22.

The two driving gears 17 are rotatably connected to the inside of the corresponding hollow tube 3. When it is necessary to spray anesthetic at different angles of the trachea, the non-standard motor 16 is started, and its output end drives the two driving gears 17 to mesh and rotate, so that the threaded cylinder 9 rotates, causing the threaded cylinder 9 to drive the threaded rod 8 to move on the sealing plate 10, driving the bearing plate 6 and a part of the medicine administration tube 4 to move. Thus, through the arrangement of the rotating shaft, when a part of the medicine administration tube 4 moves, one end of the medicine administration tube 4 moves up and down to adjust the spraying angle of the medicine administration tube 4 and spray anesthetic at different positions of the trachea;

[0047] A sealing plate 10 connected to one of the hollow tubes 3 is rotatably sleeved on the surface of the threaded rod 8.

The rotation plate 12 is rotatably connected to the corresponding hollow tube 3 through a rotating shaft. On one side of the upper surface of the rotation plate 12, an electric push rod 13 fixedly connected to the corresponding hollow tube 3 is fixedly connected.

A through groove corresponding to the sealing plate 10 is formed on the surface of one of the hollow tubes 3, and the rotation plate 12 corresponds to the drug delivery tube 4;

[0050] The other hollow tube 3 is a visual and operable guide wire insertion port. An optical fiber lens is built inside the hollow tube 3, and a visual screen can be externally connected to the tail to achieve visualization and visually observe the inside of the patient's trachea.

[0051] Specifically, when the difficult intubation type multi-functional tracheal catheter is used: the connector 29 is connected to an external device, the catheter body 1 is inserted into the patient's trachea, the airbag 2 is inflated through the mutual cooperation of the control box 27 and the air inlet pipe 26, so that the airbag 2 deforms to support the trachea and the catheter body 1. Through the mutual cooperation of the connecting block 18 and the conical block 19, high-frequency jet ventilation is carried out on the corresponding hollow tube 3, so that gas enters the inside of the connecting block 18 and the conical block 19 and is injected into the trachea through the guide pipe 20 to make the trachea ventilated;

[0052] Through the arrangement of the drug delivery tube 4, the anesthetic is transported to the inside of the patient's trachea through the drug delivery tube 4. When it is necessary to spray anesthetic at different angles of the trachea, the non-standard motor 16 is started, and its output end drives the two driving gears 17 to mesh and rotate, so that the threaded cylinder 9 rotates, and the threaded cylinder 9 drives the threaded rod 8 to move on the sealing plate 10, driving the bearing plate 6 and a part of the drug delivery tube 4 to move. Thus, through the arrangement of the rotating shaft, when a part of the drug delivery tube 4 moves, one end of the drug delivery tube 4 moves up and down to adjust the spraying angle of the drug delivery tube 4 and spray and administer drugs to different positions of the trachea;

[0053] When it is necessary to spray anesthetic deep into the trachea, the electric push rod 13 is started, and its output end drives the rotating plate 12 to rotate inside the corresponding hollow tube 3, so that the rotating plate 12 abuts against a point of the medicine delivery tube 4. Through the cooperation of the abutting block 14, the medicine delivery tube 4 is deformed, the diameter of the medicine delivery tube 4 is adjusted, so as to adjust the pressure of the anesthetic inside the medicine delivery tube 4 and the spraying distance of the anesthetic, so that the anesthetic can be administered to different depths of the trachea.
