Abstract

The utility model provides an improved Y-shaped trachea sleeve pipe, which comprises an outer sleeve pipe 1, an inner sleeve pipe 2 and an inner core 3. The utility model is characterized in that the inner arc radius of the outer sleeve 1 is reduced to 35 mm, and radian is 75 to 78 DEG; the radian and the arc length of the inner sleeve pipe 2 is mutually corresponding to the outer sleeve pipe 1; the back side direction of the inner sleeve pipe 2 is provided with a side ear hole 4, and is adhered with a cover cap 5; the radian and the arc radius is medium; the radian of the sleeve pipe which is inserted in trachea can not be over bent, and the arc length is proper; the outer sleeve pipe 1 with required model number and the matched inner core 3 are inserted in the trachea; then the inner core is withdrawn, is inserted in the corresponding inner sleeve pipe 2 and is fixed; after operation, the tracheal sleeve pipe with moderate radian and arc radius can not injure the mucous membrane of the front wall of the trachea and blood vessels because of the improper body positions of patients, etc. Thus the utility model has the advantages of improving medical operation and reducing the pain of patients.

Description

A kind of follow-on trident tracheal casing pipe

This utility model relates to a kind of follow-on trident tracheal casing pipe.

Present hospital trident tracheal casing pipe commonly used, its critical piece has inside and outside sleeve pipe and inner core, during operation sleeve pipe is inserted in the trachea, the sleeve pipe front end is close to the trachea antetheca, because telescopic radian is curved excessively, arc length is long, the mucosa and the blood vessel of easy damaged trachea antetheca, cause trachea internal hemorrhage even massive hemorrhage, its post-operative complication brings painful and threat to life to patient, also makes diagnosis and nursing work complicated more busy.

This utility model is intended to propose a kind of radian and the arc radius is moderate, can reduce follow-on trident tracheal casing pipe of tracheal injury.

The follow-on trident tracheal casing pipe that the utility model proposes, comprise inner sleeve, trocar sheath and inner core, the inner arc radius that it is characterized in that trocar sheath is reduced to 35mm, radian is at the 75-78 degree, the radian of inner sleeve and arc length are mutual corresponding with trocar sheath, the hole of picking up the ears is offered in the back side of inner sleeve, and with block.

Because the follow-on trident tracheal casing pipe that the utility model proposes has the said structure characteristics, in it, the setting of trocar sheath radian and arc radius length, it is theory according to human anatomy, normal anatomical position of trachea and clinical practice draw, radian and arc radius are moderate, the sleeve pipe radian of inserting trachea can be not curved excessively, arc length is also suitable, the trocar sheath and the supporting inner core of required model are inserted in the trachea, extract inner core again, inject corresponding inner sleeve and fix, postoperative, this radian and the moderate tracheal casing pipe of arc radius, people's position former thereby damage trachea antetheca mucosa and blood vessel such as improper due to illness do not improved curative activity, reduce the patient suffering, the port lid of picking up the ears of inner sleeve is blocked a shot well, can link to each other with respirator, and the effect in the hole of picking up the ears is to be convenient to inhale expectorant, injection and oxygen supply.

Below in conjunction with embodiment and accompanying drawing this utility model is further described.

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

Fig. 2 is the combination sketch map of this utility model embodiment trocar sheath and inner core;

Fig. 3 is the combination sketch map of this utility model embodiment trocar sheath and inner sleeve.

With reference to Fig. 1, Fig. 2 and Fig. 3, the follow-on trident tracheal casing pipe that the utility model proposes, comprise trocar sheath 1, inner sleeve 2 and inner core 3, the inner arc radius that it is characterized in that trocar sheath 1 is reduced to 35mm, radian is at the 75-78 degree, the diameter length that the outer arc radius of trocar sheath 1 is trocar sheath increases the inner arc radius, the radian of inner sleeve 2 and arc length are mutual corresponding with trocar sheath 1, the hole 4 of picking up the ears is offered in the back side of inner sleeve 2, and with block 5, because the said structure characteristics are arranged, in it, the setting of trocar sheath radian and arc radius length, it is theory according to human anatomy, normal anatomical position of trachea and clinical practice draw, radian and arc radius are moderate, the sleeve pipe radian of inserting trachea can be not curved excessively, arc length is also suitable, the trocar sheath and the supporting inner core of required model are inserted in the trachea, extract inner core again, inject corresponding inner sleeve and fix postoperative, this radian and the moderate tracheal casing pipe of arc radius, people's position former thereby damage trachea antetheca mucosa and blood vessel such as improper due to illness not, improved curative activity, reduced the patient suffering, the port lid of picking up the ears of inner sleeve is blocked a shot well, can link to each other with respirator, the effect in the hole of picking up the ears is to be convenient to inhale expectorant, injection and oxygen supply.
