Problems solved by technology

[0004] The second is the bonding molding before leaving the factory, that is, the joint extension tube and the inserted catheter are connected as a whole through glue curing. This kind of catheter is also formed before leaving the factory, but because the bonding molding is to glue the two materials Bonded together, the service life and drug resistance will be worse than injection molding, and it may fall off in later use
However, because this connection method is easy to fall off during use, and it is prone to infection, it is generally stipulated in clinical practice that this kind of external connection needs to be replaced in about 5-7 days, and the usage rate is low.
If the connection between the joint extension tube and the inserted catheter is closer to the puncture point, it will be troublesome to replace and the catheter will easily come out

Embodiment 1

[0032] Such as Figure 1~5 As shown, this embodiment is an integrated connection device, including: a female connector 1, a male connector 2 that can be screwed to the female connector 1, a handshake 3 located at the end of the male connector 2, and a limit column integrally formed with the handshake 3 4. The breaking point 5 integrally formed with the male connector 2 . The female connector 1 is a Luer connector with an internal thread; the male connector 2 is a Luer connector with an external thread, and the conical surface of the male connector 2 is uniformly coated with a medical grade sealant. Handshake 3, the outer surface is formed with vertical grain protrusions. In the present embodiment, the limit column 4 is a flat sheet structure arranged on the circumferential surface connecting the handshake 3 and the male joint 2, there is no connection between the limit column 4 and the male joint 2, and the limit column 4 and the handshake 3 The connected edges form gaps who...

Embodiment 2

[0036] This example is to verify the airtightness and antibacterial ability of the integrated connection device in Example 1.

[0037] 1. Experimental equipment: biological safety cabinet, incubator, nutrient solution, sterilized heparin cap, sterile gloves, sterilized syringe, medical 75% alcohol, bacterial solution (staphylococcus aureus solution).

[0038] 2. Experimental setup:

[0039] Control group 1:

[0040] Male connector 2 (not coated with medical grade sealant) and female connector 1 were placed at 58°C for 106 days (equivalent to three years at room temperature), and male connector 2 was connected to female connector 1 before the experiment (eight groups);

[0041] Experiment 1 group:

[0042] Male connector 2 (coated with medical grade sealant) and female connector 1 in Example 1 were placed at 58°C for 106 days (equivalent to three years at room temperature), and male connector 2 was connected to female connector 1 before the experiment (eight groups).

Embodiment 3

[0058] In this embodiment, the integrated connection device in Embodiment 1 is applied to the intravenous catheter, and the female connector 1 and the male connector 2 are connected through the connection and positioning method described in Embodiment 1 to form an integrated connection device, and the female connector of the integrated connection device One end of the connector 1 is connected with the insertion catheter of the venous catheter, and one end of the male connector 2 of the integrated connection device is connected with the infusion extension tube of the venous catheter. The connection between the male connector 2 and the infusion extension tube is realized by injection molding. The venous catheter of this embodiment can realize a completely airtight connection between the catheter and the infusion extension tube through the integrated connection device after the catheter is placed, which does not increase the difficulty of the design of the catheter and the way of ...

Abstract

The invention discloses an integrated connecting device. The device comprises a female joint, a male joint, a handle, a twisting-off point and a limiting column, wherein the male joint is capable of being connected with the female joint, the handle is located on the end portion of the male joint, the twisting-off point achieves the connection between the handle and the male joint, the twisting-offpoint is set to be a connecting weak point between the handle and the male joint, and the limiting column is connected with the handle and used for limiting the breakaway of the handle. The integrated connecting device has the advantages that the device serves as an external connecting structure, the design difficulty of a catheter is reduced, in addition, during the use of the integrated connecting device, after the male joint and the female joint are connected and positioned, the position between the male joint and the female joint cannot be changed manually through the handle, the handle cannot fall off from the male joint, the male joint is protected from other external forces, and it is ensured that the compact connection between the male joint and the female joint during the use ismaintained.

Description

technical field [0001] The invention relates to the field of clinical medical devices, in particular to an integrated connecting device. Background technique [0002] At present, there are three main forms of the connection structure between the insertion catheter of the venous catheter and the joint extension tube: [0003] The first is injection molding before leaving the factory, that is, the joint extension tube and the insertion catheter are integrally molded by injection molding at high temperature. This kind of catheter has been injection molded before leaving the factory. Although it will not fall off in the later use process, it has higher requirements on the product molding process and more difficult product design. Therefore, it is often used in product operation. quite complicated. This structure is used in the market such as CVC (central venous catheter) and PICC (peripheral central venous catheter). [0004] The second is the bonding molding before leaving t...
