Abstract

The utility model relates to a rubber lid for a forceps mouth of an electronic digestive canal endoscope, which belongs to a medical appliance accessory. The utility model which is made of rubber comprises a lid body (2), wherein, the upper part of which is a combining part with a plugging head (4) and the lower part of which is a sleeve mouth which is combined with a forceps mouth (1); the middle part of a diaphragm (7) which is arranged between the combining part and the sleeve mouth is provided with a small hole (8); the sleeve mouth is composed of an outer sleeve ring (10) and an inner sleeve tube (11), and the outer edge of the bottom of the inner sleeve tube is provided with a non-return valve plate (9). In the process of biopsy or lavage, the non-return valve plate (9) can prevent gastric juice from back flowing; the appliance is withdrawn after an operation is completed, the upper mouth of the lid body is blocked by the plugging head to ensure gastric juice not to flow back.

Description

Electronics alimentary tract endoscope forceps channel serum cap

This utility model belongs to medical apparatus and instruments, particularly relates to the forceps channel serum cap on a kind of electronics alimentary tract endoscope.

Electronics alimentary tract endoscope (hereinafter to be referred as " scope "), medical treatment and diagnostor that internal medicine is often used have been become at present, forceps channel on it is the insertion mouth of biopsy pliers and other assistive devices, patient's vomiting causes that gastric juice flows backwards when preventing that apparatus from inserting, be provided with pliers bolt rubber at the forceps channel place, in the hope of playing the effect of valve, neither hinder the insertion of apparatus, can avoid liquid to flow backwards again.But, because the aging and apparatus of pliers bolt rubber itself causes damage to it when inserting unavoidably, therefore the situation that gastric juice flows backwards even gushs often appears in actual use, again because this forceps channel is positioned at the top of endoscopic technic portion just, direction is over against holding the mirror operator, therefore gastric juice flows backwards even can be sprayed onto on operator's the body, has not only besmirched apparatus and environment, brings inconvenience also for medical examination and operation.

The purpose of this utility model promptly is to provide a kind of novel endoscopic forceps rim of the mouth serum cap, replaces the not good pliers bolt rubber of result of use, in the hope of the situation of avoiding gastric juice to flow backwards better.

Electronics alimentary tract endoscope forceps channel serum cap is made with rubber, and lid (2) is the garden tubular, it is characterized in that the top of lid is and the joint portion of block head (4) that the bottom is and the bonded running-on of forceps channel (1), one deck barrier film (7) is arranged between the two, and barrier film central authorities leave an aperture (8); Running-on is made up of outer collar (10) and inner sleeve (11), and the bottom outer rim of inner sleeve is provided with fluid stopping valve block (9).

Electronics alimentary tract endoscope forceps channel serum cap with said structure, in carrying out biopsy or lavation process, fluid stopping valve block (9) can prevent that gastric juice from flowing backwards, after end of operation is extracted apparatus out, with block head the suitable for reading of lid blocked, can guarantee that gastric juice can not flow backwards.

Accompanying drawing partly discloses installation position of the present utility model and structure thereof:

Fig. 2, electronics alimentary tract endoscope forceps channel serum cap section of structure (block head does not cover);

Fig. 3, fluid stopping valve block and running-on location diagram.

As shown in Figure 1, this utility model is installed in electronics alimentary tract endoscope forceps channel (1) and locates.

In embodiment of the present utility model shown in Figure 2, electronics alimentary tract endoscope forceps channel rubber is stamped the lid (2) that is the garden tubular, the top of lid can cooperate with block head (4), be the combine compactness of reinforcement block head with lid, one annular projection (5), the corresponding site of lid are arranged at bottom, the outer garden of block head then is one ring groove (3).In addition, for easy to use and prevent that block head from losing, between block head (4) and lid, be provided with a frenulum (6).The lid bottom is and the bonded running-on of forceps channel, is made up of outer collar (10) and inner sleeve (11), and the bottom outer rim of inner sleeve is provided with fluid stopping valve block (9).There is one deck barrier film (7) middle part of lid, and barrier film central authorities leave an aperture (8), are convenient to the insertion of apparatus.
