Abstract
The invention discloses an anti-pollution syringe. The anti-pollution syringe comprises an outer tube and a plunger rod which is inserted into the outer tube, wherein one end of the plunger rod is connected with a sealing plug, the other end of the plunger rod stretches out of the outer tube and is fixedly connected with a push-pull handle, one end of the outer tube is connected with a needle, the a retaining piece is arranged on the outer edge of the end of the other end of the outer tube, a limiting ring is fixedly sheathed at one end, close to the push-pull handle, of the plunger rod, an elastic airbag which is sheathed on the plunger rod is hermetically connected between the limiting ring and the retaining piece, and the elastic airbag is communicated with a buffer bag for relieving pressure through a fine hose. The anti-pollution syringe provided by the invention has the advantages that hands of an operator do not touch the plunger rod and the sealing plug during solution preparation, the plunger rod and the sealing plug do not touch external air, cross infection of liquid medicine during operation of the syringe can be effectively avoided, and the medication safety is guaranteed.
Description
Technical field
the invention belongs to technical field of medical instruments, be specifically related to a kind of anti-pollution injector.
Background technology
?the medicine adding syringe generally used in Hospitals at Present 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.
Summary of the invention
The object of the invention is for the deficiency in above-mentioned technology, a kind of anti-pollution injector is provided, this syringe plunger rod and sealing-plug in the process of making up a prescription do not reach the hands of operator, also outside air is not contacted, cross-contamination to medicinal liquid when effectively can prevent operating syringe, ensures drug safety.
The technical scheme that the present invention realizes above-mentioned purpose employing is: a kind of anti-pollution injector, comprise urceolus and be plugged in the plunger rod in urceolus, plunger rod one end connects sealing-plug, the other end stretches out urceolus, and be fixedly connected with push-pull handle, described urceolus one end connecting needle, the outer, termination of the other end of urceolus is provided with catch, on described plunger rod, one end fixed cover near push-pull handle is provided with spacing ring, the elastic bag be set on plunger rod is sealedly connected with between spacing ring and catch, elastic bag is communicated with the impact bag for slowing down pressure by small hose.
Removably connect between described impact bag and elastic bag.
beneficial effect
Anti-pollution injector provided by the invention, in the process of making up a prescription, plunger rod and sealing-plug do not reach the hands of operator, do not contact outside air yet, cross-contamination to medicinal liquid when effectively can prevent operating syringe, ensure drug safety, and structure is simple, easy to use, be suitable for applying.
