Embodiment 1

[0018] Such as figure 2 The shown connection seat structure for injection includes a connection seat body 2, the connection seat body 2 has a connection port 20 connected to the injection head 100 of the syringe, a connection head 21 connected with an injection piece, and a connection port 20 and the connecting channel 22 of the connecting head 21, a check valve 3 is arranged in the connecting channel 22, and the check valve 3 is opened or closed by the injection head 100 of the syringe.

[0019] In this embodiment: the injection part is a needle 40, and the structure of the one-way valve 3 is: it has an elastic component, and a hole that can shrink and close is opened on the elastic component.

[0020] Such as Figure 4 Shown: when in use, insert the injection head 100 of the syringe into the connection port 20 of the connecting seat body 2, press it through the hole on the elastic part by manpower, and due to the elastic contraction, the surrounding of the injection ...

Embodiment 2

[0022] Such as image 3 The structure of the connection seat for injection shown in this embodiment is basically the same as that of Embodiment 1, except that the injection part is an infusion tube 41 .

[0023] In this application, the one-way valve 3 is opened or closed by the injection head 100 of the syringe, which is different from the traditional one-way valve 3 opened by liquid pressure: when sampling (such as blood), the blood pressure usually does not have a large enough The pressure will automatically open the one-way valve 3, which is only suitable for injection with external pressure; while the present application is a two-way check valve, which is suitable for injection and sampling.

Abstract

The invention relates to a connecting base structure for injection. The connecting base structure comprises a connecting base body. The connecting base body is provided with a connecting port connected with an injection head of a needle cylinder, a connector connected with an injection piece and a connecting channel connecting the connecting port and the connector, the connecting channel is internally provided with a one-way valve, and the injection head of the needle cylinder opens or closes the one-way valve. According to the connecting base structure for injection, the one-way valve is arranged in the connecting base body and is opened or closed through the injection head of the needle cylinder, the both-way stopping function on liquid medicine and samples is achieved, safety and sanitation are achieved, hidden danger of virus spreading is reduced, and the connecting base structure is simple and suitable for different injection devices.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a connection seat structure for injection. Background technique [0002] In the medical process, it is necessary to inject medicinal liquid into the patient's body or sample the patient for diagnosis or treatment, and the used syringe is mainly a syringe. like figure 1 As shown: the syringe includes a barrel 10 , a piston 11 , and an injection head 100 is provided at the end of the barrel 10 . When performing an injection, injection or sampling is performed by connecting the injection head 100 to an injection needle or an infusion tube. But at present, when the injection or sampling is completed and the injection head 100 is pulled out, liquid back or dripping is easy to occur, and there is a hidden danger of virus transmission. Contents of the invention [0003] The purpose of the present invention is to provide a connection seat structure for injection. [0004] In order to...
