Abstract
The utility model discloses a tracheal tube for a cavum laryngis operation, which aims to provide the tracheal tube which can be beneficial to the cavum laryngis operation, can not obviously increase the air passage resistance and block the ventilation. The key point of the technical scheme is that the tracheal tube is provided with scales, the back end of the tracheal tube is connected with a connection tube, the front end of the tracheal tube is provided with a cuff, the cuff is connected with a pressure display ball and an inflation valve through a cuff guide tube, the guide tube which is arranged at the back of the cuff and positioned at the cavum laryngis part becomes thinner, and the inner diameter of the thin part of the guide tube is 2-6mm.
Description
Technical field
This utility model is that endotracheal tube is used in a kind of cavum laryngis operation, belongs to a kind of medical treatment device.
Background technology
The operation of cavum laryngis portion often needs the general anesthesia of tracheal intubation whole body; anesthesia is share same air flue jointly with surgical doctor; because endotracheal tube has occupied the space of most of cavum laryngis; regular meeting influences operation technique; need thinner endotracheal tube during operation; but endotracheal tube again can not be too thin, because meticulous conduit can increase airway resistance, makes air flue intrinsic pressure too high and cause dysfunction of ventilation.
Summary of the invention
In order to overcome the shortcoming that used endotracheal tube is unfavorable for the cavum laryngis operation technique, this utility model provides a kind of cavum laryngis operation to use endotracheal tube, can help cavum laryngis portion operation technique, can obviously not increase airway resistance again and hinder ventilation.
This utility model can be realized by following technical solution: have scale on the endotracheal tube, its rear end is connected with connection tube, front end has the cover capsule, the cover capsule is connected with pressure display ball and charge valve by the cover ductus bursae, the conduit that is positioned at cavum laryngis portion at cover capsule rear attenuates, and the catheter diameter of taper portion is 2～6mm.
The beneficial effects of the utility model are:
1, because have only the conduit of cavum laryngis portion to attenuate, so neither can cause the obvious rising and the dysfunction of ventilation of airway pressure, help operation technique again.
2, have simple in structurely, be easy to make convenience operation.
Description of drawings
Fig. 1 is a side view of the present utility model;
Fig. 2 is a front elevation of the present utility model;
Wherein the 1-connection tube 2-scale 3-endotracheal tube 4-cavum laryngis conduit 5-of portion cover capsule 6-cover ductus bursae 7-pressure is indicated ball 8-draught excluder
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
The specific embodiment:
Present embodiment comprises connection tube 1 and endotracheal tube 3, the rear end of endotracheal tube 3 has scale 2, and front end has cover capsule 5, and cover capsule 5 is connected with pressure indication ball 7 and draught excluder 8 by cover ductus bursae 6, rear at the cover capsule is the cavum laryngis portion conduit 4 that attenuates, and the internal diameter of cavum laryngis portion conduit 4 is 2～6mm.
During use endotracheal tube is inserted trachea, the conduit that attenuates just in time is positioned at the cavum laryngis place, has so both helped the operation of cavum laryngis portion operation, can obviously not increase airway pressure again and hinder ventilation.
Claims (1)
1. a cavum laryngis is performed the operation and is used endotracheal tube, comprise connection tube (1) and endotracheal tube (3), the rear end of endotracheal tube (3) has scale (2), front end has cover capsule (5), cover capsule (5) is connected with pressure indication ball (7) and draught excluder (8) by cover ductus bursae (6), it is characterized in that: the conduit that is positioned at cavum laryngis portion at cover capsule rear attenuates, and the internal diameter of the cavum laryngis portion conduit (4) that attenuates is 2～6mm.
