Description

Technical Field

[0001] The utility model relates to the field of medical devices, and more particularly to a medical connector. Background Art

[0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are directly or indirectly used on the human body, including the required computer software. Medical devices include medical equipment and medical consumables. [5] The utility mainly obtains through physical means, etc., rather than through pharmacological, immunological or metabolic means, or although these means are involved but only play an auxiliary role.

[0003] Currently, most of the medical connectors commonly used to connect syringes and infusion tubes are conical in shape. In the actual application process, it is found that due to the special shape of the connector itself, it is very easy to roll when placed on a support before and after the installation and disassembly of the connector. The rolling will continuously increase the contact between the connector and the outside, which may cause contamination of the connector or surrounding objects and is not conducive to use in a medical environment. Therefore, we make improvements and propose a medical connector. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a medical connector, which solves the problem that the existing medical connector is prone to rolling during use.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A medical connector includes an end tube and a tail tube that are sequentially connected end to end. The inside of the end tube and the tail tube are interconnected for the delivery of liquid medicine. The surface of the tail tube is provided with anti-slip elements, and there are at least two and they are equally spaced in the circumferential direction on the outer surface of the tail tube.

[0007] As a preferred technical solution of the present application, the anti-slip element includes a support body.

[0008] As a preferred technical solution of the present application, the top of the support body has an anti-slip boss.

[0009] As a preferred technical solution of the present application, both sides of the top of the support body have inclined plane platforms, and the inclined plane platforms are connected to the anti-slip boss in a transitional manner.

[0010] As a preferred technical solution of the present application, anti-slip convex strips are evenly laid on the surface of the inclined plane platform.

[0011] As a preferred technical solution of the present application, the cross-sectional shape of the support body is trapezoidal.

[0012] As a preferred technical solution of the present application, the interior of the tail pipe is provided with a connecting pipe for connecting with an external casing.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the solution of the present application:

[0015] 1. By providing the anti-slip element, when the needle tube is placed on the support, it can maintain a relatively stable state under the action of the support body, is not prone to sliding, which not only facilitates the stable placement before the joint installation, but also realizes the temporary storage after the joint disassembly, avoiding excessive contact between the joint and the surrounding as a whole, and is beneficial to better medical operation and use;

[0016] 2. By providing the anti-slip element, when the joint is in the actual installation state, the application of force can be better carried out through the cooperation of the inclined plane table and the anti-slip convex strip, which is more convenient for the insertion and extraction of the joint.

Such terms are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0029] As Figures 1 - 4 shown, this embodiment provides a medical connector, which includes an end tube 1 and a tail tube 11 that are sequentially connected end to end. The inside of the end tube 1 and the tail tube 11 are in internal communication for the transportation of liquid medicine. The surface of the tail tube 11 is provided with anti-slip elements 2, and there are at least two and they are evenly distributed in the circumferential direction on the outer surface of the tail tube 11. During actual use, one end of a syringe and a connecting tube are respectively inserted into the end tube 1 and the tail tube 11, thus completing the connection and installation of the medical connector;

[0030] The anti-slip element 2 includes a support body 21. The top of the support body 21 has anti-slip protrusions 22. The inside of the tail tube 11 has a connecting tube 25 for connecting with an external sleeve;

[0031] Through the setting of the anti-slip protrusions 22, the outer diameter of the tail tube 11 is larger than that of the end tube 1. And because there is a certain distance between multiple anti-slip protrusions 22, through this distance, the connecting tube can be stably placed on the corresponding support without rolling;

[0032] As a further optimization of this embodiment: both sides of the top of the support body 21 are provided with inclined plane platforms 23, and the inclined plane platforms 23 are transitionally connected to the anti-slip convex platforms 22. Through the arrangement of the inclined plane platforms 23, during the connection process of the syringe needle and the connecting tube to this joint by the operator, a lateral pushing force can be applied on the inclined plane platforms 23, so that the joint can be more easily inserted and connected to the external syringe needle and connecting tube. Compared with the traditional situation of directly pushing on the surface of the tail tube 11, the relative sliding between the operator's hand and the tail tube 11 is also reduced to a certain extent;

[0033] Anti-slip convex strips 24 are evenly laid on the surface of the inclined plane platform 23, and the cross-sectional shape of the support body 21 is trapezoidal. Through the arrangement of multiple anti-slip convex strips 24, during the actual installation process of the joint by the operator, the hand can have better frictional resistance against the inclined plane platform 23, thus ensuring the stability during its use.

[0034] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
