Abstract
The utility model relates to a once-used proportional hemostix which is composed of a quantitive blood taking needle (1), a needle holder (2), a connecting pipe (3), and an air bag (4). One end of the connecting pipe (3) is connected with the air bag (4), the other end is communicated with the quantitative blood taking needle passing through the needle holder. After the utility model is once used, the blood taking needle and the needle holder are abandoned, and the connecting pipe and the air bag can be repeatedly used. The utility model has the advantages of low cost, and convenient operation, and the cross infection can be avoided.
Description
This utility model belongs to medical mechanical domain, and is particularly a kind of for supplying the volumetric hemostix of chemical examination usefulness.
The existing quantitative hemostix, a kind of be with after carry out cleaning and sterilizing, be prone to the cross infection phenomenon; Another kind is the most frequently used quantitative suction pipe, forms disposable use by long blood taking needle and air bag.The shortcoming of its existence is because blood taking needle long (being 12cm, glass material) is prone to phenomenon and the cost height of hurting sb.'s feelings that rupture.
The purpose of this utility model is to overcome the weak point that above-mentioned prior art exists and a kind of disposable volumetric hemostix that provides, and cross infection is avoided in disposable use, and the part parts can reuse, and is not only easy to use, and with low cost.
The technical solution of the utility model is, disposable volumetric hemostix is made up of quantitative blood taking needle, needle stand, connection tube, air bag, and connection tube one end is connected with air bag, and the other end is connected with needle stand, and blood taking needle and needle stand are assembled together.
This utility model has increased connection tube and needle stand between the quantitative blood taking needle of existing structure and air bag, use once after, only get final product the needle stand that has blood taking needle is discarded, air bag, connection tube can be reused.
Illustrate below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 quantitative blood taking needle, 2 needle stands, 3 connection tubes, 4 air bags
Quantitatively blood taking needle 1 is communicated with connection tube 3 by needle stand 2, and the other end of connection tube 3 is connected with air bag 4.Needle stand (2) the one plays fixation, and the 2nd, easy to use.Blood taking needle is a glass material, and it is marked with scale; Connection tube, needle stand are made with non-toxic plastic; Air bag is made with soft rubber.During blood sampling, finger is pressed air bag 4, and with the hemorrhage place of quantitative blood taking needle 1 horizontal aligument, finger begins loosening air bag 4, and when blood volume reached requirement, finger stopped to become flexible, and blood taking needle leaves by blood sampling place, and blood-sample withdrawal is delivered in the container of splendid attire blood sample in blood taking needle 1.When carrying out taking a blood sample next time, only blood taking needle, needle stand is taken down discarded, uses new quantitative blood taking needle and needle stand instead.Can open an aperture at the top of air bag 4 in addition, its purpose is need not press air bag 4 when blood sampling, and blood can be advanced in the blood taking needle certainly, and is convenient to control blood sampling speed, avoids blood to enter in the connection tube.When needs were delivered to container containing, finger was blocked aperture, and extruding gasbag gets final product.
As a preferred embodiment, quantitatively blood taking needle length is 4-5cm, and blood sampling volume is 10～40 μ l, and blood taking needle is marked with scale.
Advantage of the present utility model:
1, realizes a people one pin, avoided cross-infection.
2, needle stand, blood taking needle exchange for conveniently, and tube connector, air bag can be reused, and be with low cost.
3, blood taking needle has shortened length.
4, manufacturing is easy.
Claims (3)
1, disposable volumetric hemostix, comprise quantitative blood taking needle (1), air bag (4), it is characterized in that between quantitative blood taking needle (1), air bag (4), increasing needle stand (2) and connection tube (3) are arranged, connection tube (3) one ends are connected with air bag (4), the other end is connected with needle stand (2), and quantitatively blood taking needle (1) is assembled together with needle stand (2).
2, hemostix according to claim 1 is characterised in that quantitative blood taking needle (1) is long for 4-5cm, and it is marked with scale, and blood sampling volume is 10～40 μ l.
3, hemostix according to claim 1 is characterised in that air bag (4) top opens an aperture.
