Description

Technical Field

[0001] The utility model relates to the technical field of safety needle seats, in particular to a safety protection needle seat that is easy to take. Background Art

[0002] In today's medical technology field, a common method of injection is to place liquid inside the syringe. The method mainly uses a push rod inside a hollow outer rod to push the liquid contained in the syringe, which is injected out from a needle tube connected to the end of the syringe to achieve the injection effect. Therefore, it is widely used in the medical community. The syringe is a common medical device. As early as the 15th century, the Italian Catinel proposed the principle of the syringe, which mainly uses a needle to extract or inject gas or liquid. The syringe can also be used for medical equipment, containers, such as some scientific instruments in chromatography to inject through a rubber diaphragm.

[0003] Injection needles are often used in hospitals. The injection needles include a needle holder, a needle body and a protective shell. The common way of use is to connect the needle holder to the syringe to inject the medicine into the patient's body for treatment. In order to avoid cross infection, the injection needle is often discarded after use to avoid secondary use. The existing needle holder has a simple structure. When discarded, the needle holder needs to be taken out together with the needle. When taking it out, the needle can easily pierce the finger, which is inconvenient to use. In addition, the bottom of the needle holder is not sealed. After use, the medicine or blood can easily flow out from the bottom of the needle holder to pollute the environment.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a safety protection needle seat that is easy to take, comprising a needle tube, an injection tube is arranged on the upper end of the needle tube, the outer side of the injection tube is cooperated with the needle seat, the upper end of the needle seat is arranged with a needle head, a rubber ring is detachably installed on the middle part of the outer side of the needle seat, a fixing ring is fixedly installed on the outer side of the rubber ring, a connecting plate is fixedly installed on the right end of the fixing ring, and a rubber plug is detachably installed on the connecting plate.

[0006] Furthermore, a piston is installed in the needle tube in a sealing manner so as to slide up and down, a piston shaft is fixedly installed on the lower end of the piston, and a handle is fixedly installed on the lower end of the piston shaft.

[0007] Furthermore, a finger hook portion is provided at the lower end of the needle tube.

[0008] Furthermore, a mounting groove is provided inside the needle seat, and the mounting groove is mounted in cooperation with the injection tube.

[0009] Furthermore, an annular groove is provided on the outer side of the needle seat, and a rubber ring is fitted in the annular groove.

[0010] Furthermore, the connecting plate is provided with an assembly hole, and a rubber plug can be detachably installed in the assembly hole.

[0011] Furthermore, the structural specifications of the rubber plug are consistent with the structural specifications of the mounting groove.

[0012] The beneficial effect of the utility model is that by pinching the rubber plug by hand and moving the rubber plug upward, the connecting plate drives the needle seat to separate from the injection tube as a whole, so that the needle seat can be safely removed without the needle hurting the hand, and then the rubber plug is taken out of the assembly hole and inserted into the installation groove to prevent the drug solution from flowing out.
