Abstract
A kind of anesthesia Dual-channel tracheal cannula of accurate positioning, belong to manufacture technology field of medical appliance, dual-lumen cannula is connected with auxiliary plate, the cross section of auxiliary plate is arc flat pipe, auxiliary plate is built with clutch for clutch control bar and bifurcated control stick, and auxiliary plate and dual-lumen cannula stick together, and have fixation clamp to press from both sides integral by the mobile jib of dual-lumen cannula and auxiliary plate, at auxiliary plate and branch breeches pipe junction, pressure switch is housed, pressure switch connects display.Oral cavity is to bronchial distance to utilize patient's X-ray before the surgery to judge, dual-lumen cannula is together inserted tracheal strips by oral cavity together with auxiliary plate, two of dual-lumen cannula bifurcated pipes are made to enter left and right bronchus respectively, when pressure switch arrives trachea carina place, display lamp is lighted, and is taken out by auxiliary plate from tracheal strips.Apparatus of the present invention make dual-lumen cannula insert trachea and become accurate, controlled.
Description
Technical field
The invention belongs to manufacture technology field of medical appliance, relate to a kind of surgery anesthesia Dual-channel tracheal cannula.
Background technology
Operation consent generally needs to anaesthetize patient, in order to ensure that patient can breathe under narcotism, being inserted, breathe by respirator by oral cavity to trachea insertion tube.Trachea dual-lumen cannula is completely isolated in order to meet left and right pulmonary ventilation, carries out pulmo and ventilates separately, to ensure patient safety and to set up felicity condition for successful surgery.The Dual-channel tracheal cannula of current application is made by plastics or rubber, one-sidedly from the lower end of dual-lumen cannula trunk extends a Ge Chang bifurcated pipe branch (left or right) downwards, and enter left side bronchus or right side bronchus, opposite side has a short bifurcated pipe.After the Dual-channel tracheal cannula applied at present inserts trachea, a left side is propped up and right Zhi Jiyi twists, Dual-channel tracheal cannula is caused to be difficult in endotracheal position expect, show according to relevant data, the success rate that this kind of Dual-channel tracheal cannula can make left and right pulmonary ventilation be separated is 65%, namely there is the 35% left and right lung isolation ventilation not reaching desirable, fail to be reached for the object that ideal conditions is set up in operation.The method that current judgement Dual-channel tracheal cannula accurately realizes the separation of left and right lung observes with branchofiberoscope the position that it inserts trachea, when position is inaccurate, also can adjust with branchofiberoscope, and branchofiberoscope could correctly must be applied by the personnel through professional training, branchofiberoscope is also very expensive; Application branchofiberoscope judges that Dual-channel tracheal cannula inserts accurate location, and Grade III Class A hospital could generally implement, and the inferior grade hospital accounting for the hospital overwhelming majority is difficult to realize.Therefore, needs are a kind of at present can assist Dual-channel tracheal cannula successfully to insert and than the device being easier to judge to insert accurate location, ensure patient safety, improves anesthesia quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of anesthesia Dual-channel tracheal cannula of accurate positioning.
The scheme of technical solution problem of the present invention adopts dual-lumen cannula and long bifurcated pipe to form, long bifurcated pipe connects the side tube chamber of dual-lumen cannula, the opposite side tube chamber connection of dual-lumen cannula parts breeches pipe on the right side, shape is for falling Y shape, dual-lumen cannula is connected with auxiliary plate, auxiliary plate is for falling Y shape, its cross section is arc flat pipe, auxiliary plate is built with clutch for clutch control bar and bifurcated control stick, auxiliary plate and dual-lumen cannula stick together, fixation clamp is had to press from both sides integral by the mobile jib of dual-lumen cannula and auxiliary plate, long bifurcated pipe and to part breeches pipe on the right side also integral by the branch breeches pipe folder of the respectively corresponding with it auxiliary plate of other fixation clamp, clutch for clutch control bar connection fixing clamp, fork arm is arranged at the bottom of bifurcated control stick, for the bar of falling Y shape, at auxiliary plate and branch breeches pipe junction, pressure switch is housed, pressure switch connects display.Oral cavity is to bronchial distance to utilize patient's X-ray before the surgery to judge, dual-lumen cannula is together inserted tracheal strips by oral cavity together with auxiliary plate, now fixation clamp is clamping, the fork arm of bifurcated control stick closes, dual-lumen cannula and auxiliary plate are easily via trunnion, then the fork arm of bifurcated control stick is opened, the angle of opening is identical with patients bronchial's angle, continue to insert dual-lumen cannula and auxiliary plate, long bifurcated pipe and part breeches pipe on the right side and enter left and right bronchus respectively, when pressure switch arrives trachea carina place, pressure switch pressurized closes, display lamp is lighted, can judge thus correctly to have inserted, stop update, by clutch for clutch control bar, fixation clamp is opened again, auxiliary plate is separated with dual-lumen cannula, auxiliary plate is taken out from tracheal strips.Wherein auxiliary plate also plays and prevents from long bifurcated pipe and part breeches pipe on the right side twisting.
Apparatus of the present invention make dual-lumen cannula insert trachea and become accurate, controlled, Dual-channel tracheal cannula location determination are become simply, clear and definite; Anesthetist can be proper use of without the need to Special Training, can extensively promote, and can significantly improve medical safety and anesthesia quality.

Fig. 4 is auxiliary plate sectional view.
Detailed description of the invention
Apparatus of the present invention are made up of dual-lumen cannula 1 and long bifurcated pipe 2, long bifurcated pipe 2 connects the side tube chamber of dual-lumen cannula 1, the opposite side tube chamber connection of dual-lumen cannula 1 parts breeches pipe 4 on the right side, shape is for falling Y shape, dual-lumen cannula 1 is connected with auxiliary plate 5, auxiliary plate 5 is for falling Y shape, its cross section is arc flat pipe, auxiliary plate 5 is built with clutch for clutch control bar 7 and bifurcated control stick 8, auxiliary plate 5 sticks together with dual-lumen cannula 1, fixation clamp 6 is had to press from both sides integral by dual-lumen cannula 1 and the mobile jib of auxiliary plate 5, long bifurcated pipe 2 and part breeches pipe 4 on the right side and also press from both sides integral by the branch breeches pipe 11 of the corresponding with it respectively auxiliary plate 5 of other fixation clamp 6, clutch for clutch control bar 7 connection fixing clamp 6, fork arm 12 is arranged at the bottom of bifurcated control stick 8, for the bar of falling Y shape, with branch breeches pipe 11 junction, pressure switch 9 is housed at auxiliary plate 5, pressure switch 9 connects display 10.
Wherein existing Dual-channel tracheal cannula is made up of dual-lumen cannula 1, long bifurcated pipe 2 and short bifurcated pipe 3, sees Fig. 1.
Auxiliary plate 5 is identical with the material of dual-lumen cannula 1.
Clutch for clutch control bar 7 is connected by axle with fixation clamp 6, and the auxiliary plate 5 of junction has cannelure, when needing to make fixation clamp 6 hold dual-lumen cannula 1 tightly, upwards pull clutch for clutch control bar 7, fixation clamp 6 tilts, and upwards pull clutch for clutch control bar 7 return when unclamping, fixation clamp 6 is the level of state.
About the bottom of bifurcated control stick 8, there are an elastomeric objects in two fork arm 12 intersections, when needs two fork arms open, bifurcated control stick 8 is to pressing down, elastomeric objects is pressed on the branch breeches pipe 11 intersection inner surface of auxiliary plate 5, when needing two fork arms to close, upwards pull bifurcated control stick 8, the distress resolves on elastomeric objects, fork arm closes.
