Background

The endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software into a whole. One has an image sensor, optical lens, light source illumination, mechanical device, etc. that can enter the stomach orally or through other natural orifices. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. For example, with the aid of an endoscopist, an ulcer or tumor in the stomach can be observed, and an optimal treatment plan can be developed accordingly. The original endoscope was made of hard tube, and was invented over 100 years ago. Although they have been gradually improved, they have not been widely used. Later, endoscopes were made in the 50's of the 20 th century with flexible tubes and were therefore able to bend easily at corners within the human body. In 1965, Harprod Hopkins installed a cylindrical lens on the endoscope to make the field of vision clearer, today's endoscopes usually have two glass fibre tubes through one of which the light enters the body, the doctor observes through the other tube or through a camera, and some endoscopes, even with micro integrated circuit sensors, feed back the observed information to the computer.

While the use of an endoscope is often accompanied by the use of reagents, existing kits used with endoscopes, such as a method and kit for bowel preparation disclosed in chinese patent publication No. CN104736177A, a method and taste-modifying kit for facilitating the washing of the gastrointestinal tract of a patient prior to a diagnostic, surgical or therapeutic procedure, can improve patient compliance and thereby improve the effect during preparation, in particular, the method makes the gastrointestinal tract preparation composition palatable for the patient's intake.

When the reagent bottle is used, one reagent is filled into the first chamber 8 through the endoscope interface 5, the other reagent is filled into the second chamber 9, the endoscope pipeline is in threaded connection with the endoscope interface, the reagent conveying pipe of the endoscope is communicated with the endoscope connecting pipe 4, when the reagent in the first chamber 8 needs to be used, the rotary cover 13 is rotated, the rotary control column 15 is driven to rotate through the rotation of the rotary control column 13, the conveying channel 27 is rotated in the rotating process of the rotary control column 15, the first baffle 23 which is rotated to the side wall of the rotary control column 15 is abutted against the fixed clamping piece 25, namely the rotary cover 13 cannot continue to rotate, at the moment, one end of the conveying channel 27 is just communicated with the connecting channel 10, the other end is just communicated with the first through hole 11, namely the first chamber 8, the first through hole 11, the conveying channel 27, the connecting channel 10 and the endoscope connecting pipe 4 are sequentially communicated, the reagent in the first chamber 8 can flow from the first chamber 8, flows into a reagent conveying pipe of the endoscope through the first through hole 11, the conveying channel 27, the connecting channel 10 and the endoscope connecting pipe 4 in sequence; when the reagent in the second chamber 9 needs to be switched to use, the spiral cover 13 can be rotated reversely, and the spiral cover 13 rotates until the second baffle plate 24 on the side wall of the rotary control column 15 abuts against the fixed clamping piece 25, namely, the spiral cover 13 cannot rotate reversely, at the moment, one end of the conveying channel 27 is just communicated with the connecting channel 10, and the other end of the conveying channel 27 is just communicated with the second through hole 12, namely, the second chamber 9, the second through hole 12, the conveying channel 27, the connecting channel 10 and the endoscope connecting pipe 4 are sequentially communicated, and the reagent in the second chamber 9 can flow into the reagent conveying pipe of the endoscope from the second chamber 9 through the second through hole 12, the conveying channel 27, the connecting channel 10 and the endoscope connecting pipe 4 in sequence; when the reagents in the first bin 8 and the second bin 9 are not needed to be used, the spiral cover 13 can be rotated to the middle section of the rotation stroke, namely, the connecting channel cannot be communicated with the first through hole 11 or the second through hole 12 through the conveying channel 27, so that a user can manage the using state of the reagents conveniently, and the using convenience of the equipment is improved.
