Plug-in check valve for medical endoscope

Abstract

A medical endoscope plug-in check valve, comprising a delivery pipe connector, a one-way axial flow seal, and a screw socket, the one-way axial flow seal is arranged between the delivery tube connector and the screw socket, and the The plug-in and buckle packaging structure is adopted between the pipe joint plug and the rotary socket, which has high packaging efficiency and can be installed and used immediately. Fix the inlaid metal nut in the inner hole of the connecting end, and the center of the metal nut coincides with the center of the inner hole of the delivery tube insertion pipe, so that when the connecting end of the mirror body tube is screwed with the metal nut, it will not be caused by excessive tightening force. The connecting pipe of the screw socket is broken, which improves the reliability and safety of the medical endoscopic equipment, and can well overcome the deficiencies in the prior art.

Description

technical field [0001] The invention relates to a medical endoscopic device, in particular to a check valve on the medical endoscopic device. Background technique [0002] With the continuous innovation and development of medical technology, various endoscopic devices for diagnosing human organs are increasing. Now endoscopic devices such as gastroscopes and colonoscopes have been widely used in the diagnosis or surgery of people's stomach, intestines and other internal organ diseases. Doctors can use endoscopic equipment to perform intuitive, accurate, fast, efficient, and low-pain diagnosis and treatment for patients, but this type of equipment is very expensive, and the conditions for use and maintenance are harsh. Regardless of electronic endoscope or fiber endoscope, The outside of the mirror body is covered with a synthetic resin protective layer, forming an airtight environment that isolates the inside from the outside world. Taking the digestive tract endoscope as a...

Problems solved by technology

[0003] Although the check valve is an accessory on the endoscope equipment, its function is very important. It is a key part connecting the probe body and the endoscope. It must have a one-way check function. Once it fails and leaks, it will Affect the normal use of the equipment, and seriously cause damage to the entire equipment, directly affecting the reliability and service life of the equipment

Existing check valve is integral structure, and it is made up of connector plug, unidirectional axial flow seal and rotary socket, and unidirectional axial flow seal is arranged between connector plug and rotary socket, and connector plug and rotary socket Glue bonding and curing packaging technology is used between them, the packaging efficiency is low, the waiting period for curing and bonding is long, and it is inconvenient for medical personnel to use. During use, the plug is connected to the main body of the endoscope, and the screw socket and the probe mirror body pipe are threaded It is connected by screw connection. In actual operation, the probe mirror body fittings need to be pulled out from the body first, and then the check valve will be removed once to separate the probe mirror body fittings from the main body of the endoscope.

The distance between the probe mirror body pipe fitting and the endoscope main body is fixed. On the one hand, the pressure force of the probe mirror body pipe fitting on the entrance of the human body increases during the pulling process, which increases the pain of the patient. The internal thread on the rotary socket of the return valve is easy to crack due to the bending and pressure of the probe mirror body, which will cause the overflow of human body fluid and increase the infection rate of medical staff
