Abstract
The utility model discloses a syringe which comprises a needle cylinder, an end cover provided with an exhaust hole, a piston and a push rod; the push rod passes through the end cover positioned at the rear part of the needle cylinder and is connected with the piston in the needle cylinder; a soft sleeve is arranged in the needle cylinder and is sleeved on the push rod; and one end of the soft sleeve is connected with the end cover, and the other end is connected with the piston. The syringe is characterized in that a molecular film air filter is arranged in the exhaust hole of the end cover; the soft sleeve is made of elastic rubber material; and the two ends of the soft sleeve are connected with the end cover and the piston in a detachable manner respectively. Due to the addition of the molecular film air filter, the possibility that liquid medicine is polluted can be reduced; and the soft sleeve has certain elasticity, so that when liquid medicine in the needle cylinder is pushed out, under the action of the soft sleeve, the push rod can draw back automatically, and then convenience is brought to operators.
Description
Technical field
This utility model relates to a kind of medical injector device, is specifically related to a kind of syringe.
Background technology
First uses glass syringe Englishman's Cathy Ferguson.The glass transparent degree is good, can see the situation of injectable drug.After this glass tubing metal is arranged and use the syringe of processing, available boiling method sterilization, syringe needle also can sharpening reuse and sterilization.The syringe of usefulness is used the plastics manufacturing now, with once promptly throwing away, the danger that infects takes place when having significantly reduced injection.In order to guarantee health, prevent cross infection, the syringe in the present age adopts the plastics quality more.
There is following defective in conventional injector: the one, all be provided with steam vent on the end cap of syringe, and set filter in the steam vent, its filter effect is not very good; The 2nd,, after push rod was released medicinal liquid, during with the push rod rollback, needing have this effort with certain power with manpower; The 3rd, the patient is in the process of treatment, and when medical personnel used conventional injector to carry out aspiration medicinal liquid, finger can touch push rod, has the contaminated possibility of medicinal liquid, causes cross infection easily, brings certain injury to the patient.
The utility model content
The purpose of this utility model is the syringe that provides a kind of antifouling property good, rational in infrastructure and easy to operate.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of syringe; Include syringe, have end cap, piston and the push rod of steam vent, said push rod passes the end cap that is positioned at the syringe rear portion and is connected with the piston of syringe, is provided with soft sleeve pipe in the said syringe; Said soft sleeve pipe interts on push rod; A soft telescopic end is connected with end cap, and the other end is connected with piston, it is characterized in that: be provided with the molecular film air filter in the steam vent of said end cap; Said soft sleeve pipe is to be formed by the elastic rubber material manufacturing.
Releasable connection is adopted with end cap and piston respectively in said soft telescopic two ends.
The beneficial effect of this utility model is: owing to set up the molecular film air filter, thus reduced the contaminated possibility of medicinal liquid; Because soft sleeve pipe has certain elasticity, so after push rod is released the medicinal liquid in the syringe, under soft telescopic effect,, brought facility for operator's use with push rod meeting automatic rollback.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further explain:
Fig. 1 is the structural representation of this utility model.
Among the figure: 1, syringe; 2, piston; 3, end cap; 4, soft sleeve pipe; 5, push rod; 6, molecular film air filter.
The specific embodiment
As shown in Figure 1; A kind of syringe includes syringe 1, has end cap 3, piston 2 and the push rod 5 of steam vent, and said push rod 5 passes the end cap 3 that is positioned at syringe 1 rear portion and is connected with the piston 2 of syringe 1; It is characterized in that: be provided with soft sleeve pipe 4 in the said syringe 1; Said soft sleeve pipe 4 interts on push rod 5, an end of soft sleeve pipe 4 and end cap 3 clampings, the other end and piston 2 clampings.Be provided with molecular film air filter 6 in the steam vent of said end cap 3.Soft sleeve pipe 4 is to be formed by the elastic rubber material manufacturing.
In a word; Though this utility model has been enumerated above-mentioned preferred implementation; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of this utility model only if such variation and remodeling have departed from the scope of this utility model.
