Abstract
The utility model relates to a disposable conjoined venous automatic quantitative hemostix. The utility model is characterized in that the utility model is composed of an outer sleeve, a blood taking needle, a rubber isolating and sealing ring, and a negative pressure blood storage tube. The utility model has the advantages of simple structure, reasonable design, reliable performance, and no phenomena of blood overflow and staxis. The flow rate of the blood can be automatically controlled, the blood can be quantitatively sampled, and the nosocomial cross infection caused by pollution can be avoided. The operation of the utility model is basically identical with the operation of an injector, and is more convenient than the operation of other venous hemostixes. The utility model is an ideal tool for venous blood sampling.
Description
The utility model relates to a kind of medical apparatus and instruments, specifically is the conjuncted vein automatic ration of disposable use hemostix.
At present, the method that China's venous blood collection mainly uses has two kinds: first method is to use the disposable syringe blood drawing, its disadvantage is that the very important person is the control blood volume, do not note slightly, just cause blood drawing too much or very few, sometimes in blood injecting tube process, cause blood to overflow the test tube contaminated environment, cause cross infection in the hospital.Second method is to use disposable automatic ration vein hemostix, this class hemostix is through clinical practice, cause blood to drip easily outward when finding still to exist blood sampling, puncture must be vacateed both hands behind the vein and negative pressure is store blood vessel be connected and could take a blood sample with puncture needle, and unskilled blood sampling person feels the drawback of bad use.
The purpose of this utility model is improved above-mentioned self-timing vein hemostix exactly, blood not only can not occur and drip phenomenon outward, and structure is perfect more, uses more convenient.
Solution of the present utility model is: by trocar sheath, blood taking needle and rubber isolating seal, circle and negative pressure storage blood vessel four parts constitute.Trocar sheath is made of the eccentric needle stand, steam vent, shirt rim and the handle that have endoporus; Blood taking needle is all to have the rustless steel tubule of certain angle ramp structure to make by two ends; One positive stop strip structure is arranged on the rubber isolating seal circle; Negative pressure storage blood vessel is stamped rubber seal plug by the test tube upper end of band scale evacuation and constitutes.
Through the disposable conjuncted vein automatic ration hemostix after improving, blood taking needle is fixed in the endoporus of eccentric needle stand, rubber isolating seal circle is placed outer sleeve inner wall, its above sealing ring near the lower bevel end of blood taking needle, rubber seal plug with negative pressure storage blood vessel below the sealing ring is close to, earlier puncture vein during blood drawing with blood taking needle, after seeing blood back, push ahead with the handgrip test tube, the lower end of blood taking needle just punctures rubber isolating seal circle, further punctures rubber seal plug, negative pressure is just passed through venous blood blood sampling needle tubing suction test tube, reach a certain amount of after, extract blood taking needle out, promptly stop blood drawing.Quite convenient during use.
The disposable conjuncted vein automatic ration hemostix that this utility model provides, simple in structure, reasonable in design, dependable performance can be controlled velocity of blood flow automatically, can also quantitatively take a blood sample, the phenomenon that can cause blood to overflow and bleed not, cross infection in the hospital that has avoided causing because of pollution.Operate this hemostix and use syringe basic identical, than more convenient with other vein hemostix.It is the ideal tools of venous blood collection.
Detailed content of the present utility model is provided by the following drawings and embodiment.
At first accompanying drawing is described:
Fig. 1 is the sketch map of the disposable conjuncted vein automatic ration hemostix off working state of expression and the structure chart of negative pressure storage blood vessel and rubber seal;
Fig. 2 is the work sketch map of the disposable conjuncted vein automatic ration hemostix of expression and the structure chart of blood taking needle and trocar sheath.
According to embodiment shown in the drawings, the structure of negative pressure storage blood vessel is to be stamped rubber or plastic seal plug (8) at pure glass that is printed on scale (13) or plastic test tube (12) upper end, and test tube (2) evacuation forms negative pressure.Trocar sheath is to be made of the eccentric needle stand (4) that has endoporus (3), steam vent (5), shirt rim (9) and handle (11).The test tube (2) that will be stamped sealing-plug (8) inserts trocar sheath shirt rim inwall (10), the upper end of its sealing-plug (8) is near rubber isolating seal circle (7) lower end, the following end in contact of sealing ring (7) upper end and blood taking needle (2), owing on the sealing ring (7) positive stop strip (6) is arranged, between sealing ring (7) upper end and inwall (10), formed a cavity, made to store the vein blood back and use.With fixing with viscose glue in blood taking needle (2) the insertion endoporus (3), on blood taking needle (2), be covered with protective sleeve (1).Corresponding end at eccentric needle stand (4) has steam vent (5).Blood taking needle and protective sleeve strict sterilization.During blood sampling; remove protective sleeve (1) earlier; after the patient skin sterilization; blood taking needle (2) is thrust human vein; when the cavity of seeing sealing ring (7) and inwall (10) has advanced blood; expression has penetrated into vein; prop up the tail end of test tube (2) with thumb; middle finger and forefinger are held the handle of stopping (11), and three refer to firmly advance simultaneously, and the lower end of blood taking needle (2) is under the effect of power; penetrate sealing ring (7) earlier; further penetrate sealing-plug (8), under suction function, venous blood flows in the test tube (12) by blood taking needle (2); during capacity pin (2) extracted from vein and stop blood drawing; remove trocar sheath, extract sealing-plug (8), just can will fill test tube (12) censorship of blood sample.
Claims (4)
1, a kind of novel disposable conjuncted vein automatic ration hemostix, its feature is: by trocar sheath, blood taking needle and rubber isolating seal circle and negative pressure storage blood vessel four parts are formed, trocar sheath one end is for having the eccentric needle stand (4) of endoporus (3), corresponding end at eccentric needle stand has a steam vent (5), at the trocar sheath other end shirt rim (9) and handle (11) is arranged.
2, disposable conjuncted vein automatic ration hemostix as claimed in claim 1 is characterized in that blood taking needle all has the rustless steel tubule of certain angle ramp structure to make by two ends.
3, disposable conjuncted vein automatic ration hemostix as claimed in claim 1 or 2 is characterized in that a positive stop strip (6) is arranged on the rubber isolating seal circle (7).
4,, it is characterized in that negative pressure storage blood vessel is made of test tube (12) the upper end cover rubber seal plug (8) of band scale (13) evacuation as claim 1 or 2 or 3 described disposable conjuncted vein automatic ration hemostixes.
