Abstract

The utility model discloses a retrocatheterism catheter, which comprises a hosepipe, a guide wire and an inflatable air bag, wherein the diameter of the hosepipe is less than that of a trachea; the guide wire runs through the hosepipe; the inflatable air bag is coated on the surface of the hosepipe; one end of the hosepipe is provided with a breathing machine interface for being connected with a breathing machine, while the other end thereof is provided with an oblique incision; a drug injection pipe with a one-way valve and an inflatable catheter with a control valve are fixed on the hosepipe; one end of the inflatable catheter is connected with the inflatable air bag, while the other end is connected with a siphon ball; one end of the guide wire is of a hook shape, while the other end thereof is coated with a hard plastic pipe; and one side of the front end of the hosepipe, which is opposite to the oblique incision, is provided with a small hole. The utility model has the advantages that by adopting the structure, retrocatheterism catheter punctures from neck by utilizing the hosepipe and the guide wire and can be conveniently inserted into the trachea; one end of the guide wire is of a hook shape, so that the guide wire can be conveniently dragged out from an oral cavity; and drug can be added conveniently through the drug injection pipe so as to reduce infection.

Description

The retrograde catheterization conduit

Technical field

This utility model relates to a kind of retrograde catheterization conduit, and intubate usefulness belongs to medical instruments field when being used for clinical anesthesia and first aid.

Background technology

When carrying out first aid for the patient, must guarantee effective ventilation, the best way of guaranteeing effective ventilation is that the patient is carried out endotracheal intubation and practices artificial respiration, and carries out other relief measure on this basis.

The tracheal intubation time is difficult for long, otherwise can delay patient's rescue, and majority is the tracheal intubation through the oral cavity at present, and this intubation procedure is that the flexible pipe front end lies across on the vocal cords easily, causes death.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of retrograde catheterization conduit, and intubate is convenient, and can carry out dosing by it simultaneously with respirator work, reduces and infects.

In order to solve the problems of the technologies described above, this utility model is realized by following measure:

A kind of retrograde catheterization conduit, comprise a diameter less than the flexible pipe of tracheal diameter, run through the seal wire of flexible pipe and be wrapped in the aerating gasbag of hose surface, described flexible pipe one end has and is used for the respirator interface that links to each other with respirator, the other end has angular cut, and be fixed with a medicine-pouring pipe and an inflating catheter that has control valve that is provided with check valve on the flexible pipe, this inflating catheter one end connects aerating gasbag, and the other end connects the siphon ball; Described seal wire one end is a hook solid, and the other end is enclosed with plastic conduit.

Further, the relative side with angular cut of described flexible pipe front end has aperture.

The beneficial effects of the utility model:

Adopt said structure, utilize flexible pipe and seal wire from the cervical region puncture, can conveniently insert trachea, seal wire one end is that hook solid can conveniently be hauled out from the oral cavity, and has medicine-pouring pipe conveniently to carry out dosing by it, reduces and infects.

Description of drawings

Fig. 1 is the structural representation of the selected embodiment of this utility model.

Among the figure 1, seal wire, 2, the respirator interface, 3, flexible pipe, 4, the siphon ball, 5, inflating catheter, 6, aerating gasbag, 7, angular cut, 8, plastic tube, 9, medicine-pouring pipe, K1, control valve, K2, check valve.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described in further details, following only is exemplary, does not limit protection domain of the present utility model.

With reference to 1 one kinds of retrograde catheterization conduits of figure, comprise a diameter less than the flexible pipe 3 of tracheal diameter, run through the seal wire 1 of flexible pipe 3 and be wrapped in the aerating gasbag 6 on flexible pipe 3 surfaces, described flexible pipe 3 one ends have and are used for the respirator interface 2 that links to each other with respirator, the other end has angular cut 7, and be fixed with a medicine-pouring pipe 9 and an inflating catheter 5 that has control valve K1 that is provided with check valve K2 on the flexible pipe 3, these inflating catheter 5 one ends connect aerating gasbag 6, and the other end connects siphon ball 4; Described seal wire 1 one ends are hook solid, and the other end is enclosed with plastic conduit 8.

Described flexible pipe 3 front ends have aperture 10 with angular cut 7 relative sides.

Operational approach of the present utility model is as follows:

The patient is lain on one's side, and with its shoulder bed hedgehopping, 2cm place above the breastbone recess, sterilization back carries out trachea puncture with the syringe needle of syringe to head, when pumpback has gas, is fixed.Take off syringe, seal wire is inserted in the trachea and advances along syringe needle, make seal wire arrive the throat wall, when opening the oral cavity with laryngoscope can see seal wire the time through glottis, seal wire is hauled out about mouthful outer 5cm, make seal wire pass plastic tube 8 and flexible pipe 3 and make flexible pipe enter trachea along seal wire 1.Withdraw from seal wire and flexible pipe 3 is fixing, and get final product connecting respirator by respirator interface 2 behind the airbag aeration.Injectable drug can be opened check valve K2 by medicine-pouring pipe 9 and inject medicine if desired, does not need just check valve K2 to be closed to get final product.

Ultimate principle of the present utility model and advantage have more than been described.This utility model is not restricted to the described embodiments, and in the prerequisite that does not break away from this utility model scope, those skilled in the art can do many changes and improvements as required.This utility model protection domain should be defined by appending claims and equivalent thereof.
