Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a contactless connector that is not easily detached. Background Technology

[0002] Contactless technology, as the name suggests, prevents direct contact between human skin and the product, acting as a barrier between the skin and the product components. Currently, most urinary catheters on the market utilize contactless technology from the very beginning of production to prevent human contamination.

[0003] Current contactless catheters are made by pressing a circular film into a flat shape and then cutting it into pieces that are wider at one end and narrower at the other. When in use, the film is manually opened into an "O" shape and inserted through the bottom of the catheter until it reaches the catheter connector. During use, the outside of the film is held firmly.

[0004] However, using a membrane as a contactless component has the following drawbacks: First, the membrane is tightly sealed on both sides during assembly, making it difficult for new operators to open, resulting in low efficiency. Second, due to the forced opening and insertion of the membrane, there is a reverse deformation force on the membrane. This means that when inserting it, the operator can open the larger opening with one hand while the smaller opening remains tightly closed, "clamping" and "supporting" the guide tube in. This inevitably affects the specially treated surface of the guide tube. Third, the membrane material is soft and prone to slipping during production and transportation, sometimes sliding to the middle or bottom, or even falling off when moving the guide tube. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a non-contact connector component that is not easily detached, thus solving the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a non-contact connector component that is not easy to detach, comprising a conduit with a connector, a sleeve provided outside the connector, an inwardly recessed ring provided at the bottom of the sleeve for abutting the bottom of the connector, and concave thin layers provided on both sides of the middle part of the sleeve.

[0009] Preferably, the thickness of the concave thin layer is thinner than the thickness of the surrounding shell body.

[0010] Preferably, the width of the deepest part of the concave thin layer is greater than the diameter of the conduit and less than the diameter of the connector.

[0011] Preferably, a protruding positioning ring is provided at the deepest part of the inner wall of the inner concave ring, and a positioning groove is provided on the outer ring at the bottom of the connector for the positioning ring to be engaged.

[0012] Preferably, the outer shell is provided with anti-slip textures spaced along its length.

[0013] Preferably, the upper section of the casing is an elliptical segment.

[0014] (III) Beneficial Effects

[0015] This invention provides a contactless connector that is not easily detached. It has the following advantages:

[0016] 1. This non-contact connector component, which is not easy to fall off, uses an inwardly recessed ring and a concave thin layer to hold the connector in place, preventing the casing from loosening on the conduit and connector. This can prevent displacement during transportation and storage, and the casing shape is relatively stable.

[0017] 2. The non-contact component of the connector that is not easy to fall off has a thin concave layer that is so thin that it is flexible, so that the concave layer can be held by hand. Based on the flexibility of the concave layer, the connector can be firmly pressed when held.

[0018] 3. The non-contact connector, which is not easy to detach, and the elliptical segment design prevent the device from rotating when laid flat, greatly improving its stability during transportation or storage. Attached Figure Description

[0023] This utility model embodiment provides a contactless connector component that is not easily detached, such as... Figure 1-3 As shown, the device includes a conduit 1 with a connector 2, and a sleeve 3 is provided outside the connector 2. The bottom of the sleeve 3 has an inwardly tapered ring 5 for abutting against the bottom of the connector 2. The inwardly tapered ring 5 at the bottom of the sleeve 3 is folded outwards. The narrowest part of the inwardly tapered ring 5 is slightly smaller than the diameter of the bottom of the connector 2. The inwardly tapered ring 5 abuts against the bottom of the connector 2 to prevent the sleeve 3 from loosening on the conduit 1 and the connector 2.

[0024] The housing 3 has concave thin layers 4 on both sides of its central part. The thickness of the concave thin layers 4 is thinner than the thickness of the surrounding housing 3 body. The concave thin layers 4 are thin enough to be flexible. The concave thin layers 4 can be held by hand, and due to the flexibility of the concave thin layers 4, the connector 2 can be firmly pressed when held.

[0025] The width of the concave thin layer 4 at its deepest point is greater than the diameter of the conduit 1 but less than the diameter of the connector 2. When the conduit 1 and connector 2 are fitted into the sleeve 3, the conduit 1 and connector 2 can easily expand the concave thin layer 4. The concave thin layer 4, due to its flexible inward contraction, just clamps the connector 2, thus preventing it from slipping off.

[0026] like Figure 2 As shown, a protruding positioning ring 7 is provided at the concaveest part of the inner wall of the inner ring 5, and a positioning groove 6 is provided on the outer ring at the bottom of the connector 2 for the positioning ring 7 to engage. During production and assembly, the sleeve 3 is inserted from the guide tube 1 and then onto the outside of the connector 2, so that the positioning ring 7 inside the sleeve 3 and the positioning groove 6 outside the connector 2 cooperate with each other. By setting the positioning groove 6 and the positioning ring 7, the sleeve 3 will not be over-exposed when it is pushed up onto the outside of the connector 2 during the assembly process.

[0027] The outer shell 3 is provided with anti-slip textures 8 spaced along its length. The anti-slip textures 8 increase the friction between the operator's hand and the shell 3.

[0028] like Figure 3 As shown, the upper section of the casing 3 has an elliptical cross-section, specifically elliptical segment 9. The elliptical segment 9 prevents the device from rotating when laid flat, greatly improving its stability during transportation or storage.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
