Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a digestive endoscope anti-reflux water delivery tube with supplemental lighting function. Background Technology
[0002] Digestive endoscopy is a group of devices that acquire images directly through the digestive tract or via ultrasound and X-ray equipment to diagnose and treat digestive system diseases. Endoscopes used in these procedures can be categorized by their type: esophagoscopy, gastroscopy, duodenoscopy, colonoscopy, enteroscopy, capsule endoscopy, cholangioscopy (including endoscopic twins), pancreatoscopy, laparoscopy, and laser confocal endoscopy. They can also be categorized by the location and function of the examination: upper gastrointestinal endoscopy, lower gastrointestinal endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic ultrasound. Finally, they can be categorized by clinical application: diagnostic digestive endoscopy and therapeutic digestive endoscopy.
[0003] During endoscopic examinations, a water supply tube is needed to rinse the examination area before the endoscope can acquire images of the area. Currently, common water supply tubes generally only have the function of rinsing. When the water supply tube is in front of the endoscope, it will block the light from the endoscope, thus affecting its use. Based on this, this invention provides a digestive endoscope anti-reflux water supply tube with supplemental lighting function. Utility Model Content
[0004] To address the aforementioned problems in the existing technology, this utility model provides a digestive endoscope anti-reflux water delivery tube with supplemental lighting function, which has the advantage of good performance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a digestive endoscope anti-reflux water delivery pipe with supplemental lighting function, comprising a flexible tube, a one-way valve installed at one end of the flexible tube, a nozzle installed at one end of the one-way valve, a water guiding chamber provided inside the nozzle, arc-shaped water outlet holes symmetrically arranged at one end of the inner wall of the water guiding chamber, a storage chamber provided in the middle of one end of the nozzle, a lighting lamp snapped into the storage chamber, and a power supply wire installed on one side of the outer wall of the lighting lamp.
[0006] As a preferred technical solution of the digestive endoscope anti-reflux water delivery pipe with supplemental lighting function according to this utility model, the nozzle is made of elastic medical plastic.
[0007] As a preferred technical solution of the digestive endoscope anti-reflux water delivery pipe with supplemental light function of this utility model, a connecting groove is provided at the other end of the inner wall of the water guiding chamber, and the connecting groove is compatible with the one-way valve.
[0008] As a preferred technical solution of the digestive endoscope anti-reflux water delivery tube with supplemental lighting function of this utility model, a No. 1 wire clamping hole is opened at the top of the storage chamber.
[0009] As a preferred technical solution of the digestive endoscope anti-backflow water delivery pipe with supplemental lighting function of this utility model, the top of the nozzle is provided with a second wire clamping hole, and a wire opening is provided on one side of the top of the nozzle near the second wire clamping hole.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The anti-backflow water supply tube for this digestive endoscope consists of a hose, a one-way valve, and a nozzle. The one-way valve prevents backflow, and the internal lighting in the nozzle provides illumination to the examination area, facilitating endoscope examination of that area.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example
[0020] Please see Figures 1-4 This utility model provides the following technical solution: a digestive endoscope anti-reflux water delivery tube with supplemental lighting function, including a flexible hose 1, a one-way valve 2 installed at one end of the flexible hose 1, and a nozzle 3 installed at the other end of the one-way valve 2. The nozzle 3 is made of elastic medical plastic, and a water guiding chamber 5 is provided inside the nozzle 3. One end of the inner wall of the water guiding chamber 5 has symmetrically arranged arc-shaped water outlet holes 6, and the other end of the inner wall of the water guiding chamber 5 has a connecting groove 4. The connecting groove 4 and the one-way valve 2 are compatible, facilitating the installation of the nozzle 3 on the one-way valve 2. A storage chamber 7 is located in the middle of one end of the nozzle 3. A first wire locking hole 8 is opened at the top of the storage chamber 7. A second wire locking hole 9 is opened at the top of the nozzle 3, located above the first wire locking hole 8. A wire opening 10 is located on one side of the top of the nozzle 3 near the second wire locking hole 9. A lighting lamp 11 is installed inside the storage chamber 7. A power supply wire 12 is installed on one side of the outer wall of the lighting lamp 11, passing through the first wire locking hole 8, the second wire locking hole 9, and the wire opening 10. The lighting lamp 11 is an existing technology device, possessing waterproof and corrosion-resistant characteristics; its specific structure and working principle will not be described in detail here.
[0021] The working principle and usage process of this utility model are as follows: During use, the rinsing salt water enters the nozzle 3 through the hose 1 and the one-way valve 2.
