Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically a contactless connector kit. 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] To address the shortcomings of existing technologies, this utility model provides a contactless connector kit, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a contactless connector kit, including a conduit with a connector, a contactless shell provided outside the connector, slots provided at equal intervals on the outer wall of the connector, and valves that can be inserted into the slots provided on the inner wall of the contactless shell. The valves are divided into several groups, and the several groups of valves are distributed circumferentially at equal angles. Each group of valves is arranged at equal intervals along the length direction of the contactless shell.

[0007] Preferably, the valve is inclined downwards, the top surface of the slot is inclined in the same direction as the valve, and the bottom surface of the slot is horizontal.

[0008] Preferably, the valves are arranged in four groups, with the four groups of valves arranged circumferentially at equal angles.

[0009] Preferably, the contactless shell is divided into an upper section and a lower section, with the upper and lower sections transitioning in a conical shape that is larger at the top and smaller at the bottom.

[0010] Preferably, the junction of the upper and lower sections is provided with a number of through holes at equal angles in the circumferential direction.

[0011] Preferably, four through holes are provided, and the four through holes are distributed around the contactless shell.

[0012] Preferably, the outer wall of the contactless shell is provided with raised stripes.

[0013] This invention provides a contactless connector kit. It has the following advantages: 1. During production and assembly, this contactless connector kit simply requires sliding the contactless shell up along the bottom of the catheter, ensuring the uppermost valve of the contactless shell mates with the lowermost slot of the connector. Compared to membranes that require cutting and creating openings, this significantly improves assembly efficiency. Furthermore, the inner wall of the contactless shell is less likely to come into contact with the outer wall of the catheter, reducing contact with the catheter during production.

[0014] 2. This contactless connector kit features a contactless housing that engages with the connector via a locking groove on the valve, preventing displacement during transportation and storage. The contactless housing maintains a stable shape on the catheter, eliminating the possibility of slipping in the opposite direction. Disassembly is also easy and convenient during recycling.

[0015] 3. When using this contactless connector kit, you can hold the contactless shell in one hand and hold the connector head with the other hand to adjust the position of the contactless shell at the connector to make the contactless shell in the optimal operating position.

[0018] This utility model embodiment provides a contactless connector kit, such as Figure 1-5 As shown, it includes a conduit 1 with a connector 2, a contactless shell 3 is provided outside the connector 2, and slots 7 are provided at equal intervals on the outer wall of the connector 2.

[0019] like Figure 4 As shown, a valve 6 that can be inserted into a slot 7 is provided on the inner wall of the contactless shell 3.

[0020] like Figure 4 As shown, the valves 6 are divided into several groups, and the groups of valves 6 are distributed circumferentially at equal angles. In this embodiment, there are four groups of valves 6, and the four groups of valves 6 are arranged circumferentially at equal angles. The valves 6 in the same layer of the four groups are separated from each other.

[0021] Each group of valves 6 is arranged at equal intervals along the length of the contactless shell 3.

[0022] like Figure 5 As shown, valve 6 is inclined downwards, the top surface of slot 7 is inclined in the same direction as valve 6, and the bottom surface of slot 7 is horizontal. The height between the bottom of the top surface and the bottom surface of slot 7 is the same as the thickness of valve 6.

[0023] The inner ring diameter of valve group 6 is greater than the outer diameter of catheter group 1.

[0024] The contactless shell 3 has a cylindrical semi-rigid shell shape. The barrel-shaped outer wall has a certain taper. Specifically, the contactless shell 3 is divided into two sections, an upper section 31 and a lower section 32, which transition into a tapered shape with the upper section being larger and the lower section being smaller.

[0025] The lowest valve 6 is located at the tail end of the upper segment 31.

[0026] Several through holes 5 are provided at equal angles around the junction of the upper section 31 and the lower section 32. By providing through holes 5, the operator can observe the engagement status of the lowest valve 6 inside. When the uppermost valve 6 engages with the lowest slot 7, the upward pushing of the contactless shell 3 can be stopped, so that it is in the appropriate engagement position.

[0027] In this embodiment, a total of four through holes 5 are provided. The number of through holes 5 includes, but is not limited to, four. The four through holes 5 are distributed at 90 degrees around the contactless shell 3.

[0028] The outer wall of the contactless housing 3 is provided with raised stripes 4. The stripes 4 increase the friction between the operator and the contactless housing 3 when the operator holds it.

[0029] Working principle: During production and assembly, the uppermost valve 6 of the contactless shell 3 needs to be engaged with the lowermost slot 7 of the connector 2. When the product is unsealed and used, the contactless shell 3 can be held in one hand and the other hand can be used to hold the end of the connector 2 to adjust the position of the contactless shell 3 at the connector 2, according to actual needs.

[0030] 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.
