Abstract

Provided is a multichannel joint, which is used for anesthesia of bronchoscope and gastroscope inspection and (or) treatment, and comprises a trachea cannula (a throat cover, a tracheae incision cannula, a face shield) connection channel, a screwed pipe connection channel, a bronchoscope operation channel and a sampling hole. The trachea cannula (a throat cover, a tracheae incision cannula, a face shield) connection channel is disposed at a right angle or any included angles with the screwed pipe connection channel. A bronchoscope operation channel opening is provided with a leakproof device like a valve or an anti-avulsion thermoplastic elastic gel, and is in the same line as the trachea cannula (a throat cover, a tracheae incision cannula, a face shield) connection channel. At the time of inspection and (or) treatment, if the problem cannot be resolved through one channel, a Y-shaped channel or a channel with multiple branches can be designed. Each operation channel is provided with the leakproof device like the valve or the anti-avulsion thermoplastic elastic gel. The sampling hole can be disposed at any positions of the joint.

Description

Multi-way joint

Technical field

This utility model relate to a kind of for bronchoscopy and (or) treatment multi-way joint, two-chamber tracheal intubation, single chamber tracheal intubation, laryngeal mask, tracheostomy tube and face shield can be connected with anesthetic machine or simply respirator, can vein keep to breathe under the general anesthesia safety carry out bronchoscopy and (or) treatment, more can in trachea general anesthesia intubation respirator operate as normal, carry out safely bronchoscopy and (or) treatment, and do not influence the multi-way joint of ventilation, and can check and (or) detect partial pressure of carbon dioxide during treatment.This joint also is applicable to gastroscopic anesthesia.

Background technology

Because bronchoscopy and (or) treatment is a kind of medical act that wound property is arranged, the patient suffering is bigger for this process, local anesthesia can not be satisfied all patients, therefore can consider to use general anesthesia, but because scope doctor and anaesthetist's common air duct, bronchoscopy and (or) implement general anesthesia in the process for the treatment of suitable difficulty arranged, its key is that how to implement control on the basis that is not influencing endoscopic technic breathes.Traditional method is to insert a fine duct or utilize the bronchoscopic blow vent of hard to implement high frequency ventilation, but can not solve the relevant issues of common air duct at all.The application of laryngeal mask provides a solution for this reason since the nineties, successfully ensured the enforcement of interventional therapy under the some fibre bronchoscope in recent years, but still there is not satisfied control breath method at present, announced a multifunctional universal joint of trachea cannula (patent No.: 200810001434.8) in 2011, this joint can solve the difficult problem of anesthesia doctor and the doctor of scope section common air duct, but, this joint valve door is loaded down with trivial details, and do not have the carbon dioxide thieff hatch, monitoring has certain degree of difficulty in the art.

Summary of the invention

In order to overcome the indeterminable problem of existing joint, this utility model provides a kind of bronchoscope multi-way joint, this joint can be connected two-chamber tracheal intubation, single chamber tracheal intubation, laryngeal mask, tracheostomy tube and face shield with anesthetic machine or simply respirator, can vein keep to breathe under the general anesthesia safety carry out bronchoscopy and (or) treatment, more can in trachea general anesthesia intubation respirator operate as normal, carry out safely bronchoscopy and (or) treatment, and do not influence ventilation, and can check and (or) detect partial pressure of carbon dioxide during treatment.This joint also is applicable to gastroscopic anesthesia.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of multi-way joint comprises tracheal intubation, laryngeal mask, tracheostomy tube or face shield interface channel, corrugated tubing interface channel, bronchoscope operating walk way and thieff hatch.Described tracheal intubation, laryngeal mask, tracheostomy tube or face shield interface channel and corrugated tubing interface channel are rectangular, or are any angle, as long as be convenient to anesthesia management; Described bronchoscope operating walk way mouth is provided with valve or the anti-tear anti-gas-leak devices such as thermoplastic elastic gel that take off, thereby the seal that ensures respiration, and with the tracheal intubation tracheal intubation, laryngeal mask, tracheostomy tube or face shield interface channel are point-blank, resistance minimum in the time of can guaranteeing into mirror like this, if check and (or) during treatment, a passage can not be dealt with problems, can be designed to Y type or multiple-limb passage more, each operating walk way place is equipped with valve or the anti-tear anti-gas-leak devices such as thermoplastic elastic gel that take off, and designed bronchoscope operating walk way and tracheal intubation, laryngeal mask, tracheostomy tube or face shield interface channel angle are as far as possible little, apparatus intake resistance minimum in the time of can making operation like this; Described thieff hatch can be preferably in the corrugated tubing interface channel at any position of joint, can not influence the bronchoscope operation like this.

During use this joint is connected tracheal intubation or laryngeal mask or tracheostomy tube or face shield with anesthetic machine corrugated tubing or simply respirator, this joint has guaranteed the seal of respiratory system, the bronchoscope operating apparatus enters from the bronchoscope operating walk way, can carry out bronchoscopy and (or) treatment.This joint can vein keep to breathe under the general anesthesia mask oxygen-inspiration safety carry out bronchoscopy and (or) treatment, if the respiration inhibition anoxia takes place, the oxygen supply of can directly pressurizeing, and need not to withdraw from bronchoscope, more can in trachea general anesthesia intubation respirator operate as normal, carry out bronchoscopic inspection and (or) treatment, and do not influence ventilation, and can check and (or) detect partial pressure of carbon dioxide during treatment.There is the anti-gas-leak device at the place at the bronchoscope operating walk way, and not only convenient but also safety can keep the anesthetic machine operate as normal, thereby guarantee those who are investigated's normal ventilation.If check and (or) need stop to ventilate during treatment and the situation of lung expansion again, as long as close an end (the method can only be used for the two-chamber tracheal intubation) of the close corrugated tubing of joint at air-breathing end folder, this moment, this side respiratory system was expanded, and adapter system is airtight, therefore enough spaces are provided to checking or treating, simultaneously, opposite side is normal ventilation, thereby the oxygen that has guaranteed the patient supplies.If single channel can not satisfy treatment, can select Y type or multiple-limb more, thereby reach under the situation of normal ventilation bronchoscopic inspection and (or) treatment, when checking, can detect partial pressure of carbon dioxide by thieff hatch.

The beneficial effects of the utility model are: can vein keep to breathe under the general anesthesia mask oxygen-inspiration safety carry out bronchoscopy and (or) treatment, if the respiration inhibition anoxia takes place, the oxygen supply of can directly pressurizeing, and need not to withdraw from bronchoscope, more can in trachea general anesthesia intubation respirator operate as normal, carry out bronchoscopic inspection and (or) treatment, and do not influence ventilation, and can check and (or) detect partial pressure of carbon dioxide during treatment, there is the anti-gas-leak device at the place at the bronchoscope operating walk way, not only convenient but also safety.This joint also is applicable to gastroscopic anesthesia.
