Abstract
The utility model relates to a disposable sealing ring type aseptic syringe which is formed by connection of a syringe jacket which is provided with a scale line, and a push rod, wherein the push rod presents a circular pipe shape or a cross rod shape, the front end of the push rod presents a tapered shape and a pressing handle is arranged on the end of the push rod. The utility model is characterized in that grooves which are inlaid with sealing rings are respectively arranged around the outer side on the front end of the push rod, each groove can be provided with a sealing ring, and the sealing rings can also be arranged on the grooves at intervals or singly; the outer side surface of the pressing handle on the end of the push rod presents a concave shape. Compared with a piston type structure, the specific sealing ring type structure on the front end of the push rod of the syringe can effectively save sealing material and the toxicity and the side effect caused by contact of physic liquor and a conical surface of a piston which is made of rubber is thoroughly eliminated. Each sealing ring is made of materials, such as silica gel, PVC, etc., and thus, each sealing ring does not have the toxicity and the side effect. Because the outer side surface of the pressing handle on the end of the push rod presents the concave shape, the design is humanized, people can feel comfort and easiness when the people touch the pressing handle and the pressing handle is convenient for propulsion of physic liquor when an injection process is carried out. The utility model has the advantages of simple structure, convenient processing, good sealing performance and secure use.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly disposable use sealing ring type asepsis injector.
Background technology
At present, disposable syringe constitutes by the syringe jacket that has graduation mark, push rod and piston connection.Piston is the bullet that rubber is made, because the characteristic of its chemical material of rubber has certain toxic and side effects, particularly directly contacts liquid medicine injection, and health is easily caused bad influence.Moreover the push rod end is the plane by the hands lateral surface, and this structural design makes operating handle not good enough, make troubles for medical personnel's work.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, a kind of safety and sanitation, good airproof performance is provided, has no side effect, the disposable use sealing ring type asepsis injector of comfortable feel during operation.
The technical scheme that this utility model adopted is for achieving the above object: disposable use sealing ring type asepsis injector, connecting institute by syringe jacket that has graduation mark and push rod constitutes, push rod is cylindrical or cross is shaft-like, and the push rod front end is tapered, and the push rod end is provided with presses hands; It is characterized in that the push rod front end is respectively equipped with the groove of inlaying sealing ring around its outside, each groove all can be provided with sealing ring, also can be at interval or the single sealing ring that is provided with; The push rod end be concave shaped by the hands lateral surface.
Described groove and sealing ring can be provided with 1～4 respectively.
Described sealing ring also can be made as an integral body and directly be inserted in the push rod front end.
The beneficial effects of the utility model are: the distinctive sealing ring type structure of this injector push-rod front end quite piston cylinder operator is effectively saved encapsulant, thoroughly eliminates the made piston conical surface of rubber and contacts the toxic and side effects of bringing with medicinal liquid.Sealing ring adopts materials such as silica gel, PVC, has no side effect; Even adopt elastomeric material to make, also reduce the side effect that it brings greatly, and can reduce cost because the required rubber consumption of sealing ring is few.The push rod end be concave shaped by the hands lateral surface, it designs hommization more, comfortable feel is light, advances medicinal liquid when being convenient to inject.This utility model is simple in structure, is convenient to processing, good airproof performance, health safe in utilization.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
Among the figure: 1 syringe jacket, 2 push rods, 3 press hands, 4 grooves, 5 sealing rings.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation this utility model provides:
Referring to Fig. 1, this utility model connects institute by the syringe jacket 1 that has graduation mark and push rod 2 and constitutes, and push rod 2 is cylindrical or cross is shaft-like, and push rod 2 front ends are tapered, and push rod 2 ends are provided with presses hands 3; It is characterized in that push rod 2 front ends are respectively equipped with the groove 4 of inlaying sealing ring 5 around its outside, each groove 4 all can be provided with sealing ring 5, also can be at interval or the single sealing ring 5 that is provided with; Push rod 2 ends be concave shaped by hands 3 lateral surface.The hands 3 of pressing that is concave shaped is fit to finger pushing medicinal liquid very much, and the human nature of structural design turns to medical personnel's injection operation convenience is provided.
Described groove 4 and sealing ring 5 can be provided with 1～4 respectively.For example: be provided with 3 grooves, forward and backward groove 4 is inlayed sealing ring 5 respectively, and intermediate groove 4 is vacant.Or being provided with 2 grooves 4, its groove 4 all can be provided with sealing ring 5, also can only be provided with 1 sealing ring 5.
Described sealing ring 5 also can be made as an integral body and directly be inserted in push rod 2 front ends.
In the enforcement, can make up respectively as required, collocation arbitrarily is to reach excellent sealing performance and to save encapsulant, in order to reducing cost.
This utility model can be made all size according to same design concept as required, all should belong within this utility model creation scope.
Claims (3)
