Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning brush technology, specifically a multifunctional cleaning brush for duodenoscopes. Background Technology
[0002] Flexible duodenoscopes are commonly used to treat digestive tract diseases. As reusable instruments that penetrate the body cavity, they require thorough cleaning and sterilization after use to prevent the spread of disease during examinations. However, due to their complex structure, narrow lumen, and especially the unique structure of the tip forceps, many areas are difficult to clean, such as valves and observation windows, which are prone to bacterial growth and hiding. During reprocessing, cleaning personnel often fail to thoroughly clean these hidden areas, resulting in ineffective reprocessing and the potential for infection from residual bacteria during subsequent use.
[0003] Currently, endoscope cleaning personnel still use ordinary gastrointestinal endoscope cleaning brushes when cleaning flexible endoscopes. Ordinary gastrointestinal endoscope cleaning brushes are mainly used to clean the various channels and buttons of the endoscope, but they do not have the function of cleaning the tip of the endoscope. Furthermore, the tip of the duodenoscope has a complex structure, which increases the difficulty of cleaning. Ordinary gastrointestinal endoscope cleaning brushes cannot meet the cleaning requirements of the duodenoscope. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional cleaning brush for duodenoscopes, which has the advantages of effectively cleaning the tip of the endoscope, adapting to the complex structure of the tip of the duodenoscope, and providing more comprehensive cleaning. It solves the problem that ordinary gastrointestinal endoscope cleaning brushes cannot clean the tip of the endoscope and cannot meet the cleaning requirements of duodenoscopes.
[0005] This utility model discloses a multifunctional cleaning brush for duodenoscopes, including a cleaning handle. A curved brush head is fixedly mounted on the left side of the cleaning handle, an ultrafine brush head is fixedly mounted on the right side of the cleaning handle, a coarse brush head is fixedly mounted on the front of the cleaning handle, and a fine brush head is fixedly mounted on the back of the cleaning handle. Two additional brush heads are added to both sides of the original cleaning brush, forming a novel flexible endoscope cleaning brush with four functions in one. This utility model addresses the complex structure of the duodenoscope tip by adding a curved brush head. The curved brush head can conform to the groove inside the lifting forceps at the tip of the duodenoscope, increasing the contact surface of the groove and improving the cleaning quality. An ultrafine brush head is added to the other end. During the treatment of patients, the duodenoscope is repeatedly raised and lowered, transferring various contaminants to the moving part of the lifting forceps' wire. However, current flexible endoscope cleaning brushes cannot extend the brush head into the moving part of the wire, failing to effectively clean the tip and severely affecting the cleaning quality of the duodenum. The added ultrafine brush head can better complete the cleaning task and better reduce infections caused by incomplete endoscope cleaning.
[0006] This utility model discloses a multifunctional cleaning brush for duodenoscopes, wherein the cleaning handle is cross-shaped and the bending angle of the curved brush head is 135°.
[0007] This utility model discloses a multifunctional cleaning brush for duodenoscopes, wherein the coarse brush head, the cleaning handle, and the fine brush head are arranged in a straight line, and the coarse brush head and the fine brush head are arranged symmetrically about the cleaning handle.
[0008] This utility model discloses a multifunctional cleaning brush for duodenoscopes, wherein the curved brush head, the cleaning handle, and the ultrafine brush head are arranged in a straight line, and the curved brush head and the ultrafine brush head are arranged symmetrically about the cleaning handle.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. Based on the original endoscope cleaning brush, this utility model adds a curved brush head and an ultra-fine brush head, which makes the cleaning brush fit the endoscope tip better and adapt to the complex structure of the duodenoscope tip. It can better remove the biofilm on the endoscope tip, achieve better cleaning quality, and better reduce infection caused by incomplete endoscope cleaning. Attached Figure Description

[0015] Please see Figure 1 This utility model discloses a multifunctional cleaning brush for duodenoscopes, including a cleaning handle 1. A curved brush head 4 is fixedly mounted on the left side of the cleaning handle 1, an ultrafine brush head 5 is fixedly mounted on the right side of the cleaning handle 1, a coarse brush head 2 is fixedly mounted on the front of the cleaning handle 1, and a fine brush head 3 is fixedly mounted on the back of the cleaning handle 1. By adding two brush heads to the sides of the original cleaning brush, a new type of flexible endoscope cleaning brush with four functions is formed. This utility model addresses the complex structure of the tip of the duodenoscope by adding a curved brush head 4, which can conform to the duodenoscope. The groove inside the lifting forceps at the tip increases the contact surface and improves the cleaning quality. An ultra-fine brush head 5 is added to the other end. During the treatment of patients with a duodenoscope, the lifting forceps are repeatedly raised and lowered, which transfers various contaminants to the moving part of the lifting forceps' steel wire. However, the current flexible endoscope cleaning brush cannot extend the brush head into the moving part of the steel wire, and cannot effectively clean the tip, which seriously affects the cleaning quality of the duodenum. The added ultra-fine brush head 5 can better complete the cleaning task and better reduce the infection caused by incomplete endoscope cleaning.
[0016] The cleaning handle 1 is cross-shaped, and the curved brush head 4 has a bending angle of 135°.
[0017] The coarse brush head 2, the cleaning handle 1, and the fine brush head 3 are arranged in a straight line, and the coarse brush head 2 and the fine brush head 3 are arranged symmetrically about the cleaning handle 1.
[0018] The curved brush head 4, the cleaning handle 1, and the ultra-fine brush head 5 are arranged in a straight line, and the curved brush head 4 and the ultra-fine brush head 5 are arranged symmetrically about the cleaning handle 1.
[0019] When using this invention: two brush heads are added to both sides of the original cleaning brush, forming a new type of flexible endoscope cleaning brush with four functions; this invention addresses the complex structure of the duodenoscope tip by adding a curved brush head 4, which can fit into the groove inside the duodenoscope tip lifting forceps, increasing the contact surface of the groove and improving the cleaning quality; an ultra-fine brush head 5 is added to the other end. During the treatment of patients, the duodenoscope is repeatedly raised and lowered, which will transfer various contaminants to the inside of the lifting forceps' moving wire. However, the current flexible endoscope cleaning brush cannot extend the brush head into the inside of the moving wire, and cannot effectively clean the tip, seriously affecting the cleaning quality of the duodenum. The added ultra-fine brush head 5 can better complete the cleaning task and better reduce the infection caused by incomplete endoscope cleaning.
