Abstract
本发明涉及一种医用防交叉感染注射器，包括针筒、针头和针头座，针头固定设置在针头座上，针筒通过头部与针头座配合连接，所述针筒外套设有外套桶，且针筒的尾部固定连接在外套桶的底部，外套桶的内壁与针筒的外壁之间形成环形通道，外套桶桶口端设有挡环，针筒的侧壁设置有与该环形通道相连通的通气孔，所述环形通道内设置有环形活塞，环形活塞通过连杆与套设在针筒上的推拉环连接。本发明的防交叉感染注射器，结构简单，没有传统注射器中与手指接触的推杆以及与药液接触的活塞，直接利用推拉环移动形成负压抽吸药液，能有效防止操作注射器时对药液的交叉污染，保证用药安全。
The invention relates to a medical anti-cross-infection injector, comprising a syringe, a needle and a needle holder, the needle is fixedly arranged on the needle holder, the needle cylinder is connected with the needle holder through the head, the outer casing of the syringe is provided with an outer barrel, and The tail of the syringe is fixedly connected to the bottom of the outer barrel, and an annular channel is formed between the inner wall of the outer barrel and the outer wall of the syringe. The vent hole, the annular passage is provided with an annular piston, and the annular piston is connected with a push-pull ring sleeved on the syringe through a connecting rod. The anti-cross-infection syringe of the present invention has a simple structure, without the push rod in contact with the finger and the piston in contact with the liquid medicine in the traditional syringe, and directly uses the push-pull ring to move to form a negative pressure suction of the liquid medicine, which can effectively prevent the medicine from being contaminated during the operation of the syringe. Eliminate cross-contamination of liquid to ensure drug safety.
Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of medical anti-cross infection syringe.
Background technology
At present, the medicine adding syringe generally used in hospital is common syringe, be made up of syringe, piston and push rod, medical personnel are moved by push rod push-and-pull piston when operating, realize the operation such as aspiration medicinal liquid, admixing medical solutions, the process of making up a prescription is: inserted by syringe in medicinal liquid bottle and extract a small amount of medicinal liquid; Then extract syringe and insert in powdered medicine bottle, liquid medicine injection is entered in powdered medicine bottle, after medicated powder and medicinal liquid dissolve completely, then extracting out in mixed liquor injection infusion bottle.But find in actual use, medical personnel are when carrying out the operation such as aspiration medicinal liquid, admixing medical solutions, and finger can touch push rod, there is the contaminated possibility of medicinal liquid, affecting drug safety.And make up a prescription in process above-mentioned, because medicine bottle is hermetically-sealed construction, therefore can produce certain Negative Pressure Difference during operation, operation is required great effort very much.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of medical anti-cross infection syringe is provided, this syringe directly utilizes push-and-pull ring to move and forms negative pressure-pumping medicinal liquid, and the pollution to medicinal liquid when effectively can prevent operating syringe, ensures drug safety.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of medical anti-cross infection syringe, comprise syringe, syringe needle and needle holder, syringe needle is fixedly installed in needle holder, head and the needle holder of syringe are connected, overcoat bucket is arranged with outside described syringe, and the afterbody of syringe is fixedly connected on the bottom of overcoat bucket, circular passage is formed between the inwall of overcoat bucket and the outer wall of syringe, overcoat bucket bung end is provided with baffle ring, the sidewall of syringe is provided with the passage be connected with this circular passage, annular piston is provided with in described circular passage, annular piston is connected with the push-and-pull ring be set on syringe by connecting rod.
Described passage is arranged on the position near syringe afterbody.
Described passage place is provided with the thin film of permeable watertight.
beneficial effect
Anti-cross infection syringe provided by the invention, structure is simple, do not have in conventional syringe with the push rod of finger contact and the piston that contact with medicinal liquid, directly utilize push-and-pull ring to move formation negative pressure-pumping medicinal liquid, cross-contamination to medicinal liquid when effectively can prevent operating syringe, ensures drug safety.
