Abstract
The utility model belongs to the field of medical equipment, a liquid syringe is joined in marriage to filtration formula is related to, including core bar, cylinder, plug, infundibulate filter screen, needle file and rust -resistant ball. The infundibulate filter screen is installed inside the cylinder, connects the needle file position, the under shed and the butt joint of needle file connector of infundibulate filter screen, and the diameter of rust -resistant ball is greater than infundibulate filter screen under shed diameter, is located infundibulate filter screen upper shed department. When joining in marriage liquid syringe suction liquid medicine, rust -resistant ball leaves the infundibulate filter screen under the effect of liquid medicine, and the liquid medicine directly gets into in the cylinder through the filter screen through the gap of rust -resistant ball and infundibulate filter screen upper shed, non flowing. When joining in marriage the liquid syringe to the container drain, the cylinder is vertical downwards, and rust -resistant ball is under the effect of gravity in the roll -in infundibulate filter screen to stop up the under shed of infundibulate filter screen, make the liquid medicine in the lateral wall filter screen entering needle file through funnel formula filter screen, realize the filtration of the fume in the solution under the effect of pressure.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of filtering type dosing syringe.
Background technology
The clinical treatment of disease, very important a kind for the treatment of means is, by intravenous method, injecting liquid drug is entered human body.During intravenous injection, medicinal liquid is directly entered in human body by syringe needle, owing to configuring in the process of medicinal liquid, inevitably produce the microgranule that naked eyes are difficult to observe, the glass granules etc. such as, produced when vial is opened, these microgranules inevitably enter into medicinal liquid in the process of making up a prescription, and then enter in patient body with medicinal liquid, cause adverse influence to the health of patient.
In the controlled environment such as hospital or clinic, although there is sterile working, antibacterial or virus etc. are controlled to greatest extent, still may there is the polluter having more latency.The medicine of such as liquid form is usually stored in in rubber membrane sealing of lid container, in order to therefrom obtain a certain amount of sealing medicine in the process of making up a prescription, needs dosing syringe to extract medicine.The needle point of dispensing injector with pin pierces through rubber membrane, syringe needle is made to enter container, when syringe needle advances, rubber elastic membrane sealant around syringe needle can prevent air from infiltrating along a direction, and prevent liquid from overflowing along another direction, but some microgranules will be made to enter in dosing transfusion device during the covering of syringe needle on puncture through seal film and diaphragm seal, and then medicinal liquid is polluted.
Enter and the problem polluting medicinal liquid to solve microgranule, people not only have studied a lot of method, and exploitation carrys out a lot of device, but these previous trials have a lot of shortcoming, and involve great expense, inefficiency.Therefore a kind of structure simple filtering type dosing syringe is devised.
Summary of the invention
Be mixed into fume to realize filtering out in medicinal liquid in the process of making up a prescription, this utility model provides a kind of filtering type dosing syringe.
This utility model solves the technical scheme that its technical problem adopts: a kind of filtering type dosing syringe, comprises core bar, syringe, plug, funnel filter net, needle stand and antirust ball.Funnel filter net is arranged on syringe inside, and connecting needle seat is put, and the under shed of funnel filter net docks with needle stand connector, and the diameter of antirust ball is greater than funnel filter opening diameter off the net, is positioned at the online opening part of funnel filter.When dosing syringe sucks medicinal liquid, by pulling core bar, plug is moved upward, vacuum principle is utilized to extract medicinal liquid, antirust ball leaves funnel filter net under the effect of medicinal liquid, medicinal liquid passes through the gap of antirust ball and the online opening of funnel filter, do not flow through the filter screen of funnel filter net sidewall, directly enter in syringe.When dosing syringe is to container drain, syringe straight down, antirust ball rolls in funnel filter net under gravity, and block the under shed of funnel filter net, medicinal liquid is made to enter in needle stand by the sidewall filter screen of funneling drainage screen under the effect of the pressure, and then enter dosage container, realize the filtration of the fume in solution.
The beneficial effects of the utility model are: structure is simple, cheap, reliability is high, can realize the needs of filtering particle pollutant in the process of making up a prescription.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is that this utility model extracts medicinal liquid schematic diagram.
Number in the figure: 1. core bar, 2. syringe, 3. plug, 4. funnel filter net, 5. needle stand, 6. antirust ball.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated.
In FIG, it is inner that funnel filter net (4) is arranged on syringe (2), connects needle stand (5) position, the under shed of funnel filter net (4) docks with needle stand (5) connector, antirust ball (6) is positioned at upper shed place of funnel filter net (4), antirust ball (6) diameter is greater than funnel filter net (4) under shed diameter, when dosing syringe (4) is to container drain, syringe (2) straight down, antirust ball (6) rolls in funnel filter net (4) under gravity, and block the under shed of funnel filter net (4), medicinal liquid is made to enter in needle stand (5) by the sidewall filter screen of funnel filter net (4) under the effect of the pressure, and then enter dosage container, realize the filtration of the fume in solution.
In fig. 2, when filtering type dosing syringe sucks medicinal liquid, by pulling core bar (1), plug (3) is moved upward, vacuum principle is utilized to extract medicinal liquid, antirust ball (6) leaves funnel filter net (4) under the effect of medicinal liquid, medicinal liquid is by the gap of antirust ball (6) with funnel filter net (4) upper shed, do not flow through the sidewall filter screen of funnel filter net (4), directly enter in syringe.
Claims (1)
1. a filtering type dispensing injector with pin, is characterized in that: it is inner that funnel filter net (4) is arranged on syringe (2), connects needle stand (5) position; The under shed of funnel filter net (4) docks with needle stand (5) connector, and antirust ball (6) is positioned at upper shed place of funnel filter net (4); Antirust ball (6) diameter is greater than funnel filter net (4) under shed diameter.
