The tracheal tube is made of non-toxic and non-stimulating hard plastic or rubber, and is of a bow shape, consisting of an outer sleeve, an inner sleeve and a core. Reticular detachable caps are disposed on the outlet of the inner sleeve and the inlet for oxygen to prevent dust in the air or foreign matters of big size entering respiratory passages, reducing opportunity of respiratory tract infection and increasing venting amount. An air-pocket is attached on the outer band of the outer tube to fully utilize functions of a breathing machine.

Description

Disposable filter dust lane air bag tracheal casing pipe

Affiliated technical field:

This utility model relates to a kind of safe, convenient, practical disposable filter dust lane air bag tracheal casing pipe.

Background technology:

Still the disposable tracheal tube that does not have at present a kind of special band filter dirt.The tracheal casing pipe of Shi Yonging is two kinds of the metal tracheal casing pipe always continued to use and disposable band air bag tracheal casing pipes clinically, these two kinds of maximum drawbacks are exactly not have the special big foreign body such as dust in the air that prevents to enter the preventer of trachea on the inner sleeve collar extension, clinically in use manyly cover the inner sleeve collar extension with sterile gauze, and, enter endotracheal purpose through tracheal casing pipe inner sleeve collar extension to reach big foreign bodies such as preventing dust in air with fixing gauze such as rubber band or other collar.This was both unhygienic, and was not convenient again, also science not, and misoperation can the tractive tracheal casing pipe cause patient's pain sometimes, increases the patient suffering.

Summary of the invention:

For the drawback on two kinds of tracheal casing pipe functions that solve clinical present use, this utility model provides a kind of disposable filter dust lane air bag tracheal casing pipe, this sleeve pipe can stop bigger foreign bodies such as dust in air, make the big foreign bodies such as gas free from dust that enter respiratory tract, change the drawback of the tracheal casing pipe of using at present, reduce the respiratory system infection of tracheotomy patients.

The technical scheme that this utility model technical solution problem is adopted is: manufacture disposable filter dust lane air bag tracheal casing pipe with nontoxic non-stimulated duroplasts or hard rubber, this sleeve pipe is arc pipe, and by trocar sheath, inner sleeve and core three parts constitute.Outer sleeve upper is a fixing head, and the plate outer end is connected with fixedly frenulum of neck, and the frenulum two ends are with binding film, and fixedly outer tube is printed on sleeve pipe caliber and model in patient's cervical region on the plate.Fixing head central authorities are inlet tube, and interior pipe enters outer tube by this mouthful, in the place ahead of mouth the card weight is arranged, and the weight plate of pipe was fixed interior pipe in the card weight can block.The inlet tube left side of trocar sheath has the air inlet pipe that communicates with air bag, air inlet pipe to be arranged in the tube wall of outer tube, and the air inlet pipe upper end has can be for the mouth of inflating of the unidirectional flap valve of inflating, and the lower end communicates with trachea.Air bag is flexible (an inotropic thin capsule, after gas entered air bag, air bag outwards enlarged, and stopped up the space between outer tube and the inner surface of trachea, helped to use respirator) around the outer tube.There is the gas outlet inner sleeve upper end, and movable axis is arranged below the gas outlet, and axle will filter the dirt detachable cap and be connected on the inner sleeve whereby.Filter dirt detachable cap can cover in the inner sleeve upper end, and the detachable cap top is network structure, but big foreign body such as the dust in the blocks air enter in the pipe, can make air unimpeded again.Right side, movable axis below is the oxygen inlet pipe, and mouth of pipe upper end is connected with oxygen inlet pipe detachable cap, and the detachable cap structure is identical with above-mentioned filter dirt detachable cap structure, can increase ventilation.The weight plate is arranged below the oxygen inlet pipe, borrow the card weight of trocar sheath to block fixedly inner sleeve, the weight plate is down the interior pipe that matches with the trocar sheath outer tube.In the pipe inner core be a solid bow-shaped structural that matches with inner sleeve, the upper end is a handle, handle down for inner sleeve in the core that matches of pipe.

The beneficial effects of the utility model are: this utility model has increased filter dirt detachable cap at the inner sleeve gas outlet and the oxygen inlet place of original tracheal casing pipe, not only increased ventilation but also big foreign bodies such as dust in air can have been stopped and entered respiratory tract, greatly reduced because of the respiratory system infection chance due to the tracheostomy tube.

Description of drawings:

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is trocar sheath crown (front and back) face structure chart.

Fig. 2 is inner sleeve crown (front and back) face structure chart.

Fig. 3 is core crown (front and back) face structure chart.

Among the figure: 1, fixing head; 2, inlet tube; 3, interior pipe; 4, outer tube; 5, active card weight; 6, weight plate; 7, air bag; 8, air inlet pipe; 9, unidirectional flap valve; 10, inflate mouth; 11, gas outlet; 12, movable axis; 13, filter dirt detachable cap; 14, oxygen inlet pipe; 15, oxygen inlet pipe detachable cap; 16, core; 17, handle.

The specific embodiment:

In Fig. 1, Fig. 2, Fig. 3, core (16) is inserted in the interior pipe (3) by gas outlet (11), interior pipe (3) is inserted in the outer tube (4) by the mouth of pipe (2), rotate active card weight (5) then weight plate (6) is blocked, use in order in the art.In tracheotomy, after tracheotomy, said apparatus (tracheal casing pipe) is inserted in patient's trachea by the intubation requirement, control handle (11) core (16) is extracted interior pipe box, air is passed in and out by tracheal casing pipe, reach the purpose of ventilation.Neck on the fixing head (1) is lain in patient's cervical region because of deciding frenulum, be used for fixing tracheal casing pipe.To filter dirt detachable cap (13) and be placed on the gas outlet (11), prevent in the air that big foreign body such as dust enters respiratory tract.When needing oxygen supply, oxygen hose detachable cap (15) can be backed out, from oxygen inlet pipe mouth oxygen supply.When needing to inhale expectorant or passing through the tracheal casing pipe administration, will filter dirt detachable cap (13) and unload, inhale expectorant or administration, will filter dirt detachable cap (13) after finishing and cover.When needing to change inner sleeve, rotate active card weight (5), inner sleeve is extracted the inner sleeve that more renews.When needing respirator, by inflate mouthful (10) gas is squeezed into air bag (7), make gap sealing between outer tube (4) and inner surface of trachea, make full use of the respirator function.

Claims (1)

1. disposable filter dust lane air bag tracheal casing pipe, it is the arc sleeve pipe that adopts nontoxic non-stimulated duroplasts or hard rubber material, its architectural feature is: this utility model is made of trocar sheath, inner sleeve and inner core three parts, at inner sleeve collar extension and oxygen inlet pipe mouth place, be provided with cancellated detachable cap.
