Abstract

The utility model is an anaesthesia trachea conduit with a big air cell and a small inner diameter, which consists of a trachea conduit (1), an open mouth in the front end of the conduit (2), a side open mouth in the front end of the conduit (3), an air cell (4), an opening hole of the air cell discharge (5), a discharge valve (6), a connecting tube of the discharge valve (7) and an outtake in the tail of the conduit (8). The device is characterized in that: the inner diameter of the air cell (4) is 25mm to 40mm, which is made of a thin-wall medical soft rubber material; the inner diameter of the trachea conduit (1) is 4.5mm to 6.5mm, which is made of the medical PVC material; the device adopts the technology of big air cell and small inner diameter, so the device makes the anaesthesia trachea conduit enlarge the operation eyeshot to the epiglottis and the glottis in the facial features department and the nonnasality department. The device can decrease the obstacle in the treatment process and make the operation much smoother; the treatment to the operation part is more thorough as well as shortening the operation time and decreasing the operation risk; the device decreases the damage to the anaesthesia trachea conduit because of the operating apparatus; the function of the trachea conduit will be more clearer; and the medical treatment effect will be much better.

Description

The little internal diameter anesthesia of air vesicle endotracheal tube
[technical field]
This utility model belongs to technical field of medical instruments, specifically, is to keep in oral cavity such as a kind of glottis, epiglottis and the pharyngeal operation general anesthesia to breathe the little internal diameter anesthesia of special-purpose air vesicle endotracheal tube.
[background technology]
At present, the kind and the model of endotracheal tube are a lot, are widely used in medical treatment clinically, and be very general in the use of emergency room, operating room and intensive care unit.The use of endotracheal tube has guaranteed the normal ventilation of lung, has avoided that the patient is obstructed because of respiratory tract, life danger appears in respiratory failure or anoxia etc.
But, when the anesthesia of some training operations, for example carrying out position operations such as epiglottis, glottis uses when anaesthetizing endotracheal tube, because existing anesthesia endotracheal tube is thick excessively, air bag is too small, at positions such as epiglottis, glottises, thick excessively endotracheal tube can form certain obstacle to operation, hinders the surgical field of view of operating doctor, therefore prolong the time of operation sometimes, even can cause operative site to handle infull situation; Too small air bag makes the result of use of anesthesia endotracheal tube be affected again; In addition, operating theater instruments in operation process, all might damage the anesthesia endotracheal tube as scalpel, operating scissors, electrosurgical etc., if the anesthesia endotracheal tube is damaged in operation process, will cause many unnecessary troubles, must in time change, if can not in time find, can influence carrying out smoothly of operation, serious meeting causes danger to patient's life.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of surgical field of view that does not influence operating doctor when positions such as department of eye and department of stomatology surgical procedure epiglottis, glottis is provided, can reduces the endotracheal tube spoilage, and the little internal diameter anesthesia of the tangible air vesicle of functional effect endotracheal tube.
The little internal diameter anesthesia of this utility model air vesicle endotracheal tube is by endotracheal tube, the catheter proximal end opening, the catheter proximal end side opening, air bag, air bag dashes the venting perforate, Air filling and discharging valves, the Air filling and discharging valves connection tube, the tail end of conduit export mixes, the catheter proximal end opening is the opening of smooth domatic, below the smooth domatic opening of catheter proximal end opening protruding end, have the catheter proximal end side opening, lower end at the catheter proximal end side opening is with air bag, have air bag on the endotracheal tube wall in air bag and dash the venting perforate, air bag dashes the venting perforate and is connected with the Air filling and discharging valves connection tube, the Air filling and discharging valves connection tube stretches out endotracheal tube in the position, posterior segment of endotracheal tube after air bag dashes one section of the downward endotracheal tube inwall walking of venting perforate, its other end connects Air filling and discharging valves, the other end of endotracheal tube is the tail end of conduit outlet, technical characterictic of the present utility model is, the internal diameter of described air bag is 25~40 millimeters (mm), and the internal diameter of described endotracheal tube 1 is 4.5~6.5 millimeters (mm).
Above-mentioned air bag adopts the thin-walled technology, makes of the medical soft elastomeric material, can produce the low pressure effect, reduces and avoid patient's air flue damage.
The little internal diameter anesthesia of this utility model air vesicle endotracheal tube has adopted little internal diameter endotracheal tube, the air bag that increases, improved the functional effect of anesthesia endotracheal tube in operation, not only make the anesthesia endotracheal tube in department of eye and department of stomatology operation, for example widened surgical field of view in the operative process of polyp of vocal cord excision, reduced the obstacle when positions such as epiglottis, glottis are handled, and the little internal diameter of air vesicle makes the effect of endotracheal tube more obvious, make operation smooth and easy, it is more thorough that operative site is handled.In addition, operating time has also correspondingly been shortened in the use of the little internal diameter anesthesia of air vesicle endotracheal tube, has reduced operation risk, has reduced the damage of the anesthesia endotracheal tube that causes because of operating theater instruments, makes medical effect better, and doctor, patient are satisfied with.
[description of drawings]
Accompanying drawing is the structural representation of the little internal diameter anesthesia of this utility model air vesicle endotracheal tube;
Among the figure, 1, endotracheal tube, 2, front opening, 3, the front opening, 4, air bag, 5, air bag dash the venting perforate, 6, Air filling and discharging valves, 7, the Air filling and discharging valves connection tube, 8, the tail end of conduit outlet.
[specific embodiment]
Below in conjunction with description of drawings, provide the specific embodiment of the little internal diameter anesthesia of this utility model air vesicle endotracheal tube.
The little internal diameter anesthesia of this utility model air vesicle endotracheal tube is made of towards venting perforate 5, Air filling and discharging valves 6, Air filling and discharging valves connection tube 7, tail end of conduit outlet 8 endotracheal tube 1, catheter proximal end opening 2, catheter proximal end side opening 3, air bag 4, tracheal tampon, endotracheal tube 1 adopts the medical PVC material, its internal diameter is 4.5~6.5 millimeters (mm), in actual fabrication, can be divided into 4.5,5.0,5.5,6.0, the plurality of specifications of 6.5mm, enable to be applicable to the patient of age grade section for many years.
