Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a water delivery device for an endoscope and an endoscope having the same. Background Technology

[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. Endoscopes can be inserted into the stomach through the mouth or other natural orifices. Endoscopes can visualize lesions that are not visible on X-rays, allowing doctors to develop optimal treatment plans.

[0003] Endoscopes include endoscope water delivery devices for supplying water. To achieve sterilization, endoscope water delivery devices are typically designed as disposable or sterilized using chemical methods. Disposable endoscope water delivery devices are more expensive to use. Chemical sterilization, on the other hand, has a longer sterilization time, and the CE and FDA recommend pressure steam sterilization for reusable medical devices. Therefore, endoscope water delivery devices sterilized using chemical methods do not meet the requirements of CE (European Community) and FDA (Food and Drug Administration).

[0004] Because the continuous rolling pressure of the peristaltic pump accelerates the aging of the peristaltic pump tubing in endoscopic water delivery systems, non-reusable silicone tubing cannot be used. Reusable peristaltic pump tubing must be made of materials with high abrasion resistance and biocompatibility (such as the high-polymer BPT). However, materials with high abrasion resistance typically have poor thermoelasticity, and expansion occurs after pressure steam sterilization, causing the connection between the peristaltic pump tubing and the connector to loosen, leading to leaks and detachment of the peristaltic pump tubing from the connector. Even applying adhesive to the connection between the peristaltic pump tubing and the connector cannot solve this problem. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a water delivery device for an endoscope is provided. The water delivery device for an endoscope includes a silicone tube, a peristaltic pump tube, a connector, and a sleeve. The peristaltic pump tube is for connection to a peristaltic pump. The silicone tube has a silicone tube connecting end, and the peristaltic pump tube has a peristaltic pump tube connecting end. The connector is connected between the silicone tube connecting end and the peristaltic pump tube connecting end to allow communication between the silicone tube and the peristaltic pump tube. The sleeve is fitted onto the peristaltic pump tube connecting end.

[0006] For example, the sleeve includes a sleeve tube fitted onto the peristaltic pump tube connection end.

[0007] For example, the fitting includes a nut, and the pipe fitting is threaded, with the nut threadedly connected to the thread to fit onto the peristaltic pump tube connection end.

[0008] For example, the fitting includes a peristaltic pump tube fitting part and a silicone tube fitting part, wherein the peristaltic pump tube fitting part is fitted onto the peristaltic pump tube connection end, and the silicone tube fitting part is fitted onto the silicone tube connection end.

[0009] For example, the peristaltic pump tubing sleeve is connected to the silicone tubing sleeve.

[0010] For example, the peristaltic pump tube connection end includes a first peristaltic pump tube connection end and a second peristaltic pump tube connection end located at both ends of the peristaltic pump tube. The silicone tube includes a first silicone tube and a second silicone tube. The tube connectors are respectively connected between the silicone tube connection end of the first silicone tube and the first peristaltic pump tube connection end, and between the silicone tube connection end of the second silicone tube and the second peristaltic pump tube connection end, so that the first silicone tube, the peristaltic pump tube and the second silicone tube are connected in sequence. The sleeve is respectively sleeved on the first peristaltic pump tube connection end and the second peristaltic pump tube connection end. The end of the first silicone tube facing away from its silicone tube connection end is used to connect to the water delivery bottle, and the end of the second silicone tube facing away from its silicone tube connection end is used to connect to the auxiliary water delivery tube.

[0011] For example, the silicone tubing and peristaltic pump tubing are arranged in a straight line, and the fittings include straight fittings.

[0012] For example, the sleeve is constructed as a silicone sleeve made of silicone.

[0013] For example, the fitting is inserted into the peristaltic pump tubing connection, which is held between the sleeve and the fitting.

[0014] According to another aspect of the present invention, an endoscope is also provided. The endoscope includes a water delivery device for any of the above-described endoscopes.

[0015] During pressure steam sterilization, the fitting in the water delivery device can tighten the peristaltic pump tubing connection, preventing it from expanding. Thus, even during pressure steam sterilization, the peristaltic pump tubing connection remains tightly sealed to the pipe fitting, preventing leaks or detachment. This allows the water delivery device to be sterilized via pressure steam, resulting in higher sterilization efficiency and compliance with CE and FDA requirements.

[0016] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0017] The advantages and features of this utility model will be described in detail below with reference to the accompanying drawings. Attached Figure Description

[0018] The following drawings, which are incorporated herein by reference as part of this invention, are provided for understanding the invention. The drawings illustrate embodiments of the invention and their descriptions, serving to explain the principles of the invention. In the drawings,

[0022] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0023] According to one aspect of the present invention, a water delivery device for an endoscope (hereinafter referred to as the water delivery device) is provided. The water delivery device can be used to deliver water. The water delivery device can be applied to any suitable device, including but not limited to an endoscope. Therefore, according to another aspect of the present invention, an endoscope is also provided. The water delivery device for an endoscope and the endoscope according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the water delivery device may include a silicone tube 100, a peristaltic pump tube 200, a pipe fitting 300, and a sleeve 400.

[0025] The silicone tube 100 may be made of silicone. Silicone has good thermal elasticity, therefore the silicone tube 100 can withstand pressure steam sterilization. The silicone tube 100 may have a silicone tube connector 101. The end of the silicone tube 100 facing away from the silicone tube connector 101 can be used to connect to components outside the water delivery device, such as a water bottle and / or auxiliary water delivery pipe.

[0026] The peristaltic pump tubing 200 can be used to connect to a peristaltic pump. The peristaltic pump can roll the peristaltic pump tubing 200, thereby providing power for the water delivery device to deliver water, which in turn allows water to pass through the silicone tubing 100 and the peristaltic pump tubing 200. The peristaltic pump tubing 200 may have a peristaltic pump tubing connection end 201.

[0027] A fitting 300 can be connected between the silicone tubing connection end 101 and the peristaltic pump tubing connection end 201 to connect the silicone tubing 100 and the peristaltic pump tubing 200. The fitting 300 includes, but is not limited to, straight fittings, right-angle fittings, or 45-degree angle fittings. The fitting 300 can be connected to the silicone tubing connection end 101 by any suitable method, such as adhesive bonding or insertion. Similarly, the fitting 300 can be connected to the peristaltic pump tubing connection end 201 by any suitable method, such as adhesive bonding or insertion.

[0028] The sleeve 400 can be fitted onto the peristaltic pump tubing connection end 201. In this way, the sleeve 400 can press the peristaltic pump tubing connection end 201 tightly. The sleeve 400 can have various structures, such as a retaining ring, a tube clamp, or a pneumatic finger. The sleeve 400 can be pre-fitted onto the peristaltic pump tubing connection end 201 before the tube connector 300 is connected, or it can be fitted onto the peristaltic pump tubing connection end 201 after the tube connector 300 is connected.

[0029] When the water delivery device undergoes pressure steam sterilization, the sleeve 400 can press tightly against the peristaltic pump tube connection end 201, thereby preventing the peristaltic pump tube connection end 201 from expanding. Thus, even during pressure steam sterilization, the peristaltic pump tube connection end 201 and the pipe fitting 300 can maintain a tight connection, preventing leakage or detachment. In this way, the water delivery device can be sterilized via pressure steam sterilization, achieving higher sterilization efficiency and meeting CE and FDA requirements.

[0030] For example, the sleeve 400 may include a sleeve tube. The sleeve tube can be sleeved onto the peristaltic pump tube connection end 201. The sleeve tube can press against the peristaltic pump tube connection end 201, thereby preventing the peristaltic pump tube connection end 201 from expanding. Furthermore, the sleeve tube has a simple structure and low manufacturing cost. The sleeve tube can be pre-sleeved onto the peristaltic pump tube connection end 201 and then connected to the pipe connector 300.

[0031] For example, the fitting 400 may include a nut. The fitting 300 may be threaded. The nut can be threaded onto the threads of the fitting 300, thereby fitting onto the peristaltic pump tubing connection 201. This configuration allows the nut to press against the peristaltic pump tubing connection 201, preventing expansion of the peristaltic pump tubing connection 201. Compared to structures such as fittings, the nut facilitates installation and removal.

[0032] For example, the sleeve 400 may include a peristaltic pump tubing sleeve 410 and a silicone tubing sleeve 420. The peristaltic pump tubing sleeve 410 can be sleeved on the peristaltic pump tubing connection end 201. The peristaltic pump tubing sleeve 410 can press the peristaltic pump tubing connection end 201, thereby preventing the peristaltic pump tubing connection end 201 from expanding. The silicone tubing sleeve 420 can be sleeved on the silicone tubing connection end 101. The silicone tubing sleeve 420 can press the silicone tubing connection end 101, thereby preventing the silicone tubing connection end 101 from expanding. Although the silicone tubing 100 is not easily expanded due to pressurized steam sterilization, the silicone tubing sleeve 420 provides protection, preventing problems such as leakage or detachment.

[0033] For example, the sleeve 400 can be a structural component, with the two ends of the sleeve 400 being the peristaltic pump tube sleeve 410 and the silicone tube sleeve 420, respectively; or, the peristaltic pump tube sleeve 410 can be connected to the silicone tube sleeve 420 by means of adhesive bonding, snap-fitting, or molding. In this way, the sleeve 400 can be a monolithic structure, with fewer components in the water delivery device, making it easier to manage.

[0034] Exemplarily, the peristaltic pump tubing connection end 201 may include a first peristaltic pump tubing connection end and a second peristaltic pump tubing connection end located at both ends of the peristaltic pump tubing 200. The silicone tubing 100 may include a first silicone tubing 110 and a second silicone tubing 120. Two connectors 300 may be included. One of the two connectors 300 may be connected between the silicone tubing connection end 101 of the first silicone tubing 110 and the first peristaltic pump tubing connection end to communicate between the first silicone tubing 110 and the peristaltic pump tubing 200. The other of the two connectors 300 may be connected between the silicone tubing connection end of the second silicone tubing 120 and the second peristaltic pump tubing connection end to communicate between the second silicone tubing 120 and the peristaltic pump tubing 200. Two sleeves 400 may be included. The two sleeves 400 may be respectively sleeved on the first peristaltic pump tubing connection end and the second peristaltic pump tubing connection end. The end of the first silicone tubing 110 facing away from its silicone tubing connection end 101 may be used to connect to a water bottle. The end of the second silicone tube 120 facing away from its silicone tube connection end 101 can be used to connect to the auxiliary water delivery pipe. With this configuration, under the action of the peristaltic pump, water can flow out from the water delivery bottle, and then pass through the first silicone tube 110, the peristaltic pump tube 200 and the second silicone tube 120 in sequence, and then flow into the auxiliary water delivery pipe.

[0035] For example, the silicone tubing 100 and the peristaltic pump tubing 200 can be arranged in a straight line. The pipe fitting 300 may include a straight pipe fitting. In this way, the resistance to water flowing through the water delivery device is small.

[0036] For example, the sleeve 400 can be constructed as a silicone sleeve made of silicone. With this configuration, the sleeve 400 can be made of the same material as the silicone tube 100. Therefore, the water delivery device of this embodiment does not introduce new materials or potential biocompatibility risks.

[0037] Exemplarily, the connector 300 can be inserted into the peristaltic pump tubing connection end 201. The peristaltic pump tubing connection end 201 can be clamped between the sleeve 400 and the connector 300. In this configuration, the connector 300 can support the peristaltic pump tubing connection end 201, preventing the sleeve 400 from squeezing and deforming it. Similarly, the connector 300 can also be inserted into the silicone tubing connection end 101. In embodiments where the sleeve 400 includes a peristaltic pump tubing sleeve portion 410 and a silicone tubing sleeve portion 420, the peristaltic pump tubing connection end 201 can be clamped between the peristaltic pump tubing sleeve portion 410 and the connector 300, and the silicone tubing connection end 101 can be clamped between the silicone tubing sleeve portion 420 and the connector 300. In this configuration, the connector 300 can support the silicone tubing connection end 101, preventing the silicone tubing sleeve portion 420 from squeezing and deforming it.
