Abstract
The utility model provides an anti-laser tracheal catheter. The anti-laser tracheal catheter comprises an outer tube, a connector, an air bag, an air charging device and a supporting steel wire, wherein the connector is arranged at the position of an opening in the front end of the outer tube, the air bag is arranged at a position near the opening in the front end of the outer tube in the direction of the axis of the outer tube, the air charging device is connected with the air bag, and the supporting steel wire is arranged in the outer tube and located between the connector and the air bag. The anti-laser tracheal catheter is characterized in that an inner tube is arranged between the supporting steel wire and the inner wall of the outer tube, and a laser protection layer is arranged between the outer tube and the inner tube. The anti-laser tracheal catheter solves the problem that an existing tracheal catheter is poor in safety performance and high in manufacturing cost and has the advantages that the structural design is ingenious, the structure is simple, surgical operation is facilitated, the price is low, the safety coefficient is high, and damage to tissue is little.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of preventing laser endotracheal tube specifically.
Background technology
Now, carbon dioxide laser operation proportion in otorhinolaryngologic operation day by day increases, but in carbon dioxide operation, existing hidden danger has also exposed out gradually.In conventional otorhinolaryngologic laser surgery, adopt general anesthesia, in art, patient can not autonomous respiration, need help patient by assisted respiartion and carry out oxygenate.In operation process, the main method adopting has two kinds, one is not carry out tracheal intubation, the benefit of this mode is exactly the visual field that does not affect patient, easy to operate, but there is the risk of the air flue of burning, particularly, the in the situation that of jet ventilation, the dust and the tumor dust that easily calcination in art are produced are brought into respiratory tract.Meanwhile, this type of breathing pattern can not guarantee that patient has enough flesh pines, may be the operation of impact operation.Another kind is to carry out tracheal intubation and control ventilation, the concentration of monitoring patient's oxygen intake and carbon dioxide, but surgical field of view is narrow, and easily there is the danger that laser is punched in art, respiratory tract injury is one of the most serious complication of this type of operation.Existing Special endotracheal tube, surface is covered by metal, easy damaged patient oral cavity and respiratory tract in intubate process, and cost is higher, has limited use crowd.
Utility model content
The purpose of this utility model is to provide a kind of preventing laser endotracheal tube, has solved existing endotracheal tube poor stability, problem that cost of manufacture is high.Its structural design is ingenious, have simple in structure, be convenient to operation technique, cheap, safety coefficient is high, to the advantage such as tissue injury is little.
The purpose of this utility model be achieved in that this preventing laser endotracheal tube comprise outer tube body, be arranged on outer tube body front opening place joint, be arranged near the aerating device being connected along the air bag of outer tube body axis direction, with air bag outer tube body front opening, in outer tube body, be arranged on supporting steel wire between joint and air bag, its technical essential is: between described supporting steel wire and outer tube body inwall, be provided with interior tube body, be provided with lasing safety layer between outer tube body and interior tube body.
Described outer tube body end sidepiece is provided with the ventilation side opening that runs through outer tube body and interior tube body.
Described lasing safety layer is made by aluminium foil or preventing laser sponge.
The advantage the utlity model has and positive technique effect are: between outer tube body and interior tube body, be provided with lasing safety layer, even outer tube body breaks in operation process, the structure that still can protect inner endotracheal tube can not penetrated by carbon dioxide laser calcination.Can reduce patient because the fine particle that in operation process, laser calcination produces etc. is drawn into tracheospasm or the tumor cell transfer that patient pulmonary causes.Tube chamber softness, can avoid, in hard outer tube body during endotracheal intubation, damage is caused in trachea, oral cavity, applied widely.Low cost of manufacture, has reduced the financial burden of patient with operation.Even in operation process, endotracheal tube has been arrived in unexpected calcination, and laser can not produce scattering process yet, and causes the damage of surrounding tissue.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1 ventilation side opening, 2 air bags, 3 supporting steel wires, 4 lasing safety layers, 5 outer tube bodies, 6 joints, 7 aerating devices, 8 interior tube bodies.
The specific embodiment
According to Fig. 1, describe concrete structure of the present utility model in detail.This preventing laser endotracheal tube comprises outer tube body 5, be arranged on the joint 6 at outer tube body 5 front opening places, be arranged near the aerating device 7 being connected along the air bag 2 of outer tube body 5 axis directions, with air bag 2 outer tube body 5 front openings, in outer tube body 5, be arranged between joint 6 and air bag 2 parts such as supporting steel wire 3.Wherein, between supporting steel wire 3 and outer tube body 5 inwalls, be provided with interior tube body 8, between outer tube body 5 and interior tube body 8, be provided with lasing safety layer 4.Outer tube body 5 end sidepieces are provided with ventilation side opening 1.Outer tube body, lasing safety layer 4, interior tube body 8, supporting steel wire 3 form four-layer structure, have guaranteed that the ventilation of endotracheal tube is safe and reliable.Lasing safety layer 4 can be selected the materials such as aluminium foil, preventing laser sponge, also the material that contains laser absorbent can be made to outer tube body.
During use, outer tube body 5 ends are connected with respirator by joint 6, and outer tube body 5 front ends insert in tracheas, by pressure filling air valve, inflating catheter by air Injection in the air bag 2 of outer tube body front end, the gap between filling outer tube body 5 and trachea.In outer tube body 5, be provided with lasing safety layer 4, stoped the damage of laser to outer tube body 5, air bag 2 etc. in bottleneck throat laser surgery, the even danger of blast of burning because oxygen concentration is too high while effectively avoiding outer tube body 5 to be burnt.
Claims (3)
1. a preventing laser endotracheal tube, comprise outer tube body, be arranged on outer tube body front opening place joint, be arranged near the aerating device being connected along the air bag of outer tube body axis direction, with air bag outer tube body front opening, in outer tube body, be arranged on supporting steel wire between joint and air bag, it is characterized in that: between described supporting steel wire and outer tube body inwall, be provided with interior tube body, between outer tube body and interior tube body, be provided with lasing safety layer.
