Endoscope disposable protection kit

The invention relates to an endoscope, in particular to an endoscope disposable protective cover.

Background technique

Because the endoscope is observed and operated deep into the patient's body cavity, it is extremely strict in terms of contact with body cavity, body fluids, and blood. However, the soft endoscope (gastroscope, colonoscopy and bronchoscope) in the endoscope is determined by its structure and material, and can not withstand the more reliable and strict disinfection, especially the thinner tube, water pipe and suction tube. Moreover, the long-term pipeline is extremely polluted, and it is difficult to meet the standard only by cleaning and disinfection. It is the ultimate goal of this topic to use a disposable film and tubing to cover and replace the body cavity, body fluids, blood and other parts of the patient inside and outside. The major endoscope manufacturers in the world have also proposed a number of programs. For example, 30 patent applications filed by American Visual Science Corporation, more than 30 patent applications filed by Olympus Japan, and more than 60 patent applications filed by Pentax Corporation of Japan. These programs are for the reliable disinfection of endoscopes. The way to make an important contribution.

4 The crown transparent film shield of the present invention has the following substantive differences compared with the comparative document US6852077B2:

a. The protective cover of the present invention has a crown shape, which can be easily worn with a large hat down on the outer side of the mirror operating portion and the vicinity thereof without being covered by the cuff; and the protective cover in the document US6852077B2 is a sleeve. Sleeve-like, some are lifted from the bottom to the top of the mirror inserting part from the bottom up, then put into the mirror operating part and put it over the mirror light guide and the doctor's left hand.

(FIG1-FIG10, FIG13, FIG. 22- FIG. 27, FIG. 36, FIG. 39-FIG42); the rest are from the side cover outside the operating portion of the mirror body, and some must be closed with adhesive strips, and some doctors' hands cannot enter the cover. protected.

b. The protective cover manufacturing material of the invention is made of transparent film, has the advantages of convenient observation, lightness and convenience, low cost and the like, and the transparent material enables the heat sealing clamp to accurately seal the three-way sealing cap under the condition that the outer surface of the film is very clear. The clamp tube in the heat sealing port is heat sealed; and the comparative document US6852077B2 is made of a non-transparent film material, which obviously does not have the above advantages of the present application.

c The fixing method of the protective cover of the invention is that the instrument inserter with the crown transparent film protective cover is elastically docked with the three-way sealing cap fixed to the operating portion of the mirror body, and is indirectly fixed on the mirror body, and the installation and disassembly are more convenient and quick. The contrast document US6852077B2 has a water gas enthalpy and suction 闽 connection; although the connection position of the mirror body and the instrument plug is close, but the manner is different, and the instrument inserter of the present invention is an existing device of the protective film, the comparison document US6852077B2 will protect The cover is attached to the lens body and then the instrument plug is attached, which is substantially different from the present application. At this point, the left hand of the doctor holding the mirror is not in the protective cover and is not protected. d. The instrument inserter provided in the present invention has two purposes: First, the protective cover is fixed on the mirror body because it is elastically fixed, mounted and disassembled by the instrument inserter and the connected three-way sealing cap. It's as easy and fast as using the elastic "snap" on the clothes, which is better than the fixed method in the existing comparison file. Second, the insertion or extraction of the instrument because the instrument inserter has an arched cavity and its closed incision, so that the dirt in the three-way sealing cap cannot be leaked. In the above four parts during disassembly: the suction tube, the suction 闽 and the crown transparent film protective cover and the three-way sealing cap can be completely removed, and the manufacturing cost is low, the operability is strong, and the utility model is convenient for popularization and application.

5 The invention enables the endoscope which can not be applied once, and the above-mentioned disposable protective cover is used as the protective cover and replacement of the consumable material, and achieves the most reliable disinfection effect of the one-time application of the endoscope, and improves the reliability of the disinfection. It shortens the disinfection time, accelerates the mirror body turnover, prolongs the life of the mirror body, and saves a lot of water and electricity consumption and medical sewage treatment costs, realizes energy saving and emission reduction, reduces the number of hospital mirrors, saves money, protects the environment, and improves the internal environment. The mobility of the speculum application. Endoscopy can carry out endoscopic diagnosis and treatment by carrying only a certain number of sterilized pouches in a place where there is no disinfection condition, and is especially suitable for field hospitals and endoscopy for emergency situations.
