Description
This utility model multifunctional disposable syringe be a kind ofly be suitable for that hospital makes the clinical injection device, adopts the liquid device, the medical apparatus of the multiple functions such as test tube of hemostix and splendid attire blood.
At present general hospital the widespread usage disposable sterilized syringe in clinical injection and blood sample collection, because this syringe is not store blood chemical examination function, behind the blood sample collection, the blood sample that needs to gather changes in the teat glass, separation of serum (slurry) is for clinical analysis, send the blood of testing to pollute easily, cause result of laboratory test error to occur, also increased the workload of scavenger.
The purpose of this utility model is to exist weak point that a kind of multifunctional disposable syringe is provided at present syringe, the syringe rear portion has passage, have brace on the syringe front end pin mouth and be connected with pin mouth medicated cap, have injection, take a blood sample, contain blood, adopt liquid, contain the multiple function of liquid, simple in structure, easy to use, safe and reliable.
The multifunctional disposable syringe takes following mode to realize: syringe construction is made of syringe, pin mouth, push rod, syringe needle, pinhead sleeve, pin mouth medicated cap.It is the syringe inlet that the syringe front end is processed with the pin mouth, pinhead sleeve is contained on the pin mouth, in order to prevent to pollute, the syringe needle outer cover is equipped with pinhead sleeve, and pin mouth front portion has groove, pin mouth hatband has brace, is sleeved on pin mouth rear portion, pin medicated cap core is arranged at pin mouth medicated cap endoporus bottom, energy tight seal pin mouth endoporus when the pin cap is enclosed within on the pin mouth, pin mouth medicated cap endoporus sidewall is provided with convex and matches with pin mouth front groove, and the pin mouth is used to be locked.There is graduation mark the syringe side, the syringe top is provided with passage, extracts push rod out after helping putting the pin medicated cap on the pin mouth of syringe in syringe, and there is outstanding side in back end of syringe portion, injection is convenient in the side, blood drawing is held the time, also just in time during centrifugalize frame on centrifuge shield.The push rod dress is inserted in the syringe Inner Front End piston, and there is handle at the rear portion, adopts cross fin and piston area to fuse.
Multifunctional disposable injector designed Rational structure is simple, can make common disposable syringe uses, also can use the disposable syringe blood drawing, dial after exsomatizing and remove syringe needle, simultaneously pusher body is pulled to the passage place at syringe top, then pin mouth cap sleeve is gone on the pin mouth of syringe and the card jail, extract push rod out, this syringe centralized procurement blood and Sheng blood have been save the step that changes test tube over to, can be directly as containing blood test tube separation of serum or blood plasma, be mixed with the anticoagulant suction or from passage adding syringe after the blood sampling, for clinical assay analysis usefulness, treat that connecting residual blood after chemical examination is finished destroys by fire in the lump, has blocked the link of cross-contamination.The multifunctional disposable syringe can adopt non-toxic plastic to make, easy to carry, remove staff's frangible trouble and worry of health check-up blood drawing teat glass of going out from, save cost again, simple and easy to do, saved simultaneously loaded down with trivial details work such as the sterilization of containing the blood teat glass and cleaning again.This utility model also is applicable to the sampling of ascites pleural fluid etc.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a multifunctional disposable syringe construction sketch map.
Fig. 2 is that this utility model syringe is made blood sampling test tube time spent sketch map.
