Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope water bottle cap that can be used in multiple ways. Background Technology

[0002] Endoscopic water and air supply accessories are key auxiliary instruments used in conjunction with endoscopes. They are primarily used to deliver sterile water to the examination cavity during endoscopic procedures to flush the field of view or remove mucus, and to provide air or carbon dioxide to maintain cavity dilation and a clear field of view. These accessories require connection to water and air supply lines via connectors. However, in current technology, the connectors are directly installed at the bottle opening, with a through-hole in the center for connecting to external lines, making a seal impossible. Reuse requires cleaning and sterilization, and they are incompatible with similar bottle caps on the market, making them particularly inconvenient to use. Utility Model Content

[0003] The technical problem this invention aims to solve is that the connector of the water and air supply accessory for endoscopes cannot be sealed and is incompatible with similar bottle caps on the market, making it inconvenient to use.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An endoscope irrigation water bottle multi-purpose cap includes an interface, a capping body, and a guide post. The capping body has a through hole at its center. The interface is located at the external through hole of the capping body, and the guide post is located at the internal through hole of the capping body. The interface surface has external threads, and the inner surface of the capping body has internal threads along the periphery of the guide post. When in use, the multi-purpose cap is placed at the mouth of a bottle containing sterile water or other solutions. The interface connects to other external interfaces, which can be various interfaces with multi-functional tubing.

[0006] Preferably, the thickness of the interface opening is less than the thickness of the interface itself. In this solution, the opening wall is made thinner, which can reduce the contact area between the external interface sealing ring and the interface, increase the pressure, and achieve a more effortless tightening and sealing effect.

[0007] Preferably, the bottom of the external thread does not contact the upper surface of the cap body, leaving space for the operator to operate.

[0008] Preferably, the upper surface of the internal thread does not contact the upper surface of the inner part of the cap body, and a silicone gasket is provided between the internal thread and the upper surface of the inner part of the cap body.

[0009] Preferably, the interface, the screw cap body, and the guide post are integrally formed.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] (1) The present invention provides a multi-purpose cap for endoscope water bottles, comprising an interface, a capping body, and a guide post. The capping body has a through hole at its center, the interface is located at the external through hole of the capping body, and the guide post is located at the internal through hole of the capping body. The interface has an external thread, and the inner side of the capping body has an internal thread along the periphery of the guide post. When in use, the multi-purpose cap for endoscope rinsing water bottles is placed at the mouth of a bottle containing sterile water or other solutions. The interface connects to other external interfaces, which can be various interfaces with multifunctional tubing. It not only provides a good sealing effect but also is compatible with various caps, making it convenient to use and more suitable for widespread adoption.

[0012] (2) In this utility model, the thickness of the interface opening is less than the thickness of the interface itself. The opening wall thickness in this solution is made thinner, which can reduce the contact area between the external interface sealing ring and it, increase the pressure, and achieve a more labor-saving tightening and sealing effect.

[0013] (3) The bottom of the external thread in this utility model does not contact the upper surface of the cap body, leaving a certain space to facilitate the operation of the operator and the force is more reasonable.

[0014] (4) The upper surface of the internal thread in this utility model does not contact the upper surface of the inner part of the cap body, and a silicone gasket is provided between the internal thread and the upper surface of the inner part of the cap body, which can ensure that the gasket does not move during use and has a good sealing effect.

[0018] In the diagram, 1-interface, 2-cap body, 3-guide post, 4-external thread, 5-internal thread, 6-gasket, 7-external interface Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] This utility model discloses a multi-functional cap for endoscope water bottles, such as... Figure 1-3 As shown, it includes an interface 1, a capping body 2, and a guide post 3. The capping body 2 has a through hole at its center. The interface 1 is located at the external through hole of the capping body 2, and the guide post 3 is located at the internal through hole of the capping body 2. The surface of the interface 1 has an external thread 4, and the inner side of the capping body 2 has an internal thread 5 along the periphery of the guide post 3. When in use, the multi-purpose cap for endoscope irrigation water bottles connects to the bottle opening containing sterile water or other solutions via the threads of the capping body 2. The interface 1 connects to other external interfaces 1, which can be various interfaces 1 with multi-functional tubing. The guide post 3 is located inside the bottle, providing not only a good seal but also compatibility with various caps, making it convenient to use and more suitable for widespread adoption.

[0021] like Figure 1 As shown, the thickness of the opening of interface 1 is less than the thickness of interface 1 itself. The opening wall thickness in this solution is made thinner, which can reduce the contact area between the external interface 7 sealing ring and it, increase the pressure, and achieve a more effortless tightening and sealing effect.

[0022] like Figure 1 As shown, the bottom of the external thread 4 does not contact the upper surface of the cap body 2, and the distance between the bottom of the external thread 4 and the cap body 2 is about 10mm, leaving space for the operator to operate.

[0023] like Figure 2 As shown, the upper surface of the internal thread 5 does not contact the inner upper surface of the cap body 2, and a silicone gasket 6 is provided between the internal thread 5 and the inner upper surface of the cap body 2. In the prior art, the thread extends to the bottom without leaving space for a sealing ring. Instead, the sealing ring is usually attached to the inside with adhesive, which is a complex process. In this application, the gasket 6 is directly placed between the internal thread 5 and the cap body 2, which not only simplifies the process but also ensures that the gasket 6 does not move during use, resulting in a good sealing effect.

[0024] In a further preferred embodiment, the interface 1, the screw cap body 2, and the guide post 3 are integrally formed.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
