a safety syringe

Abstract

The invention belongs to the field of medical equipment, and more specifically relates to a safety syringe. A safety syringe, comprising a syringe and a needle connected to the front end of the syringe, a safety sleeve is sheathed on the outside of the syringe, and a collar 1 is provided inside the safety sleeve near the tail end of the syringe. The ring 1 is provided with a contact 1 extending forward, and the needle includes a pinpin, and the pinpin is covered with a collar 2 . In the present invention, contact one and contact two are respectively arranged on collar one and collar two, and a rubber fixing ring is arranged on the outside of the needle, which can ensure that the safety sleeve is pushed forward after the syringe is used, and the needle has a similar effect on the needle. The function of isolation from the outside world ensures that the safety sleeve will not shift and fall off, effectively prevents the used needle from causing pollution and damage to the outside world, and prevents the secondary transmission of diseases; a safety sleeve disclosed in the present invention The syringe has simple structure and convenient operation, which greatly reduces the risk factor of medical staff.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to a safety syringe. Background technique [0002] Most of the syringes used for infusion and blood transfusion are disposable. Before use, the needle is covered with a needle cap to prevent the needle from contacting the outside world. After the syringe is used, the medical staff often cannot find the needle that was originally removed from the needle. cap, or there is no time to put the needle cap back on, etc., so that the needle of the used syringe is directly exposed to the outside, resulting in the pollution and damage of the used syringe needle to the external environment. The inner diameter is small, which increases the risk of the medical staff being punctured during the process of putting the needle cap back on, and is extremely likely to cause injury to the medical staff.

[0002] Most of the syringes used for infusion and blood transfusion are disposable. Before use, the needle is covered with a needle cap to prevent the needle from contacting the outside world. After the syringe is used, the medical staff often cannot find the needle that was originally removed from the needle. cap, or there is no time to put the needle cap back on, etc., so that the needle of the used syringe is directly exposed to the outside, resulting in the pollution and damage of the used syringe needle to the external environment. The inner diameter is small, which increases the risk of medical staff being punctured during the process of putting back the needle cap, which is very easy to cause injury to medical staff

In order to solve this kind of problem, a class of injection needles has appeared in the prior art, that is, a safety sleeve is added to the outside of the needle, but after use, this type of safety sleeve will often be squeezed and collided with more rubbish. The phenomenon of shedding occurs in the middle of the needle, but it still cannot 100% solve the problem of pollution and damage to the external environment by the needle of the syringe after use.
