[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] See Figures 1 to 3 This is a schematic diagram of a cleaning device 1 for a digestive endoscope 2 provided in an embodiment of the present invention. The cleaning device 1 is inserted into the forceps opening 30 of the digestive endoscope 2. The cleaning device 1 includes a cleaning tip 10, a cleaning hose 20, and multiple cleaning holes 22. The cleaning tip 10 has a cavity 13 inside, and an inlet 11 and an outlet 12 communicating with the cavity 13 are respectively provided on both sides of the cleaning tip 10. One end of the cleaning hose 20 is connected to the outlet 12, and the cleaning hose 20 has a cleaning channel 21 communicating with the outlet 12. When the cleaning device 1 is in working condition, the cleaning hose 20 is located in the forceps of the digestive endoscope 2. The cleaning holes 22 are provided on the cleaning hose 20. When the cleaning device 1 is in working condition, the inlet 11, the outlet 12, the cleaning channel 21, and the cleaning holes 22 constitute a cleaning channel for cleaning the digestive endoscope 2.

[0037] By connecting the inlet 11 and outlet 12 of the cleaning end 10 to the cleaning hose 20, a complete cleaning channel is formed, allowing the cleaning agent to enter the inner wall of the digestive endoscope 2 through the inlet 11 and clean the digestive endoscope 2. There is no need to pre-inject the cleaning agent into the forceps channel, which improves the convenience of the cleaning device 1.

[0038] Preferably, the inner wall of the cleaning pipe 21 is provided with an inner spiral pattern 23 to guide the flow of cleaning agent; wherein, from the inlet 11 to the outlet 12, the inner spiral pattern 23 rotates along a first direction; when the cleaning agent flows through the cleaning pipe 21, the cleaning agent flows along the inner spiral pattern 23 and flows out from the cleaning hole 22.

[0039] By setting an inner spiral pattern 23 on the inner wall of the cleaning pipe 21, the cleaning agent can be guided by the inner spiral pattern 23, which increases the flow rate of the cleaning agent in the cleaning hose 20, and makes the cleaning agent flow out of the cleaning hole 22 more evenly, resulting in a better cleaning effect of the cleaning hose 20.

[0040] Furthermore, the cleaning holes 22 are arranged along the direction of the inner spiral pattern 23. By arranging the cleaning holes 22 along the direction of the inner spiral pattern 23, the cleaning agent can flow through the cleaning holes 22 to the space between the outer surface of the cleaning hose 20 and the inner wall of the clamp channel while flowing along the inner spiral pattern 23.

[0041] In addition, the outer side of the cleaning hose 20 is provided with bristles 24, which are spirally arranged along the axis of the cleaning hose 20; wherein, when the cleaning device 1 is working, the bristles 24 contact the inner wall of the clamp channel; from the inlet 11 to the outlet 12, the spiral direction of the bristles 24 rotates in a second direction opposite to the first direction.

[0042] By providing bristles 24 on the outside of the cleaning hose 20, the bristles 24 can be used to scrape the dirt on the inner wall of the clamp channel, thereby cleaning the inner wall of the clamp channel; on the other hand, by setting the spiral direction of the bristles 24 and the flow direction of the cleaning agent to be opposite, a cross force can be formed between the bristles 24 and the cleaning agent, improving the uniformity of the distribution of the cleaning agent.

[0043] Preferably, the cleaning end 10 further includes a driving device, and one end of the cleaning hose 20 near the cleaning end 10 is connected to the driving device to drive the cleaning hose 20 to rotate; wherein the driving device drives the cleaning hose 20 to rotate in a second direction.

[0044] By setting a drive device to rotate the cleaning hose 20, the bristles 24 can make more thorough contact with the inner wall of the clamp channel, thereby cleaning away dirt. On the other hand, the rotation direction of the drive device is opposite to the flow direction of the cleaning agent, and the rotation of the inner spiral pattern 23 can guide the cleaning agent away from the cleaning head. The rotation direction of the drive device is the same as the setting direction of the bristles 24. After the cleaning agent flows out of the cleaning hole 22, it can be guided out of the inner wall of the clamp channel through the bristles 24, carrying away dirt and improving cleaning efficiency.

[0045] Furthermore, the end of the cleaning hose 20 away from the cleaning end 10 is provided with an inlet; wherein, when the cleaning device 1 is working, the inlet enters the clamp channel before the cleaning hose 20 to guide the cleaning hose 20 to be inserted smoothly.

[0046] The guide is made of a rigid material and has a rounded front end, which facilitates entry into the inner wall of the clamp channel. By setting the guide, the resistance encountered by the cleaning hose 20 when entering the clamp channel can be reduced, so as to avoid damage to the inner wall of the clamp channel.

[0047] In addition, the cleaning device 1 also includes multiple liquid storage tanks, which are connected to the injection port 11 of the cleaning end 10; and / or the cleaning device 1 also includes a gas storage tank, which is connected to the injection port 11 of the cleaning end 10.

[0048] By setting up multiple liquid storage chambers, different types of cleaning agents, such as enzyme detergents, disinfectants, and water, can be stored in the liquid storage chambers; while by setting up gas storage chambers, the inner wall of the clamp channel can be quickly dried after cleaning by means of the double spiral pattern.

[0049] Furthermore, in the case where the cleaning device 1 includes multiple liquid storage tanks, a pressure pump is installed inside each liquid storage tank. The pressure pump is connected to the inlet 11 and is used to control the outflow rate of the liquid within the storage tank by adjusting the output pressure. By installing a pressure pump inside the liquid storage tank, the outflow rate of the liquid within the tank can be adjusted, thereby enabling cleaning for different scenarios and making the cleaning device 1 more comprehensive in its functionality.

[0050] For example, multiple liquid storage chambers can be used in conjunction with each other. For instance, when cleaning the digestive endoscope 2, the pilot is inserted into the forceps channel. After adjusting the position, the inside of the forceps channel is first initially cleaned with warm water. Next, the valve of the enzyme cleaning agent is opened to clean the residual protein. Then, clean water is used again to remove the residual enzyme cleaning agent and protein. Subsequently, the inner wall of the forceps channel is disinfected with disinfectant. Finally, the gas storage chamber is opened to quickly air dry the inner wall of the forceps channel.

[0051] Furthermore, the cleaning end 10 is equipped with a vibration device, and one end of the cleaning hose 20 is connected to the vibration device; wherein, the vibration device generates vibration to drive the cleaning hose 20 to clean the digestive endoscope 2.

[0052] The vibration device can generate vibrations at a certain frequency, which in turn causes the cleaning tube to vibrate slightly, further loosening and peeling off the dirt on the inner wall of the clamp channel, thereby improving the cleaning effect.

[0053] Preferably, the cleaning holes 22 are non-uniformly distributed on the cleaning hose 20 to divide the surface of the cleaning hose 20 into high-density areas and low-density areas.

[0054] Some areas on the inner wall of the clamp channel have severe stains. The high-density bristles 24 can effectively target these areas, thereby improving overall efficiency.

[0055] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
