Description

Hemostix

Technical field

This utility model relates to the blood sampling instrument in the medical instruments field, the hemostix that uses when referring more particularly to blood sample collection.

Background technology

In medical and health industry, need blood sample collection in advance during blood count, the hemostix that uses during blood sample collection is exactly common injector for medical purpose usually, it mainly comprises: syringe, the top upside of syringe is provided with the needle point seat that needle point can be installed, be provided with soft piston in the syringe, soft piston is connected with push rod; Its operation principle is: at first install medical needle point on the needle point seat, then needle point is pricked into blood vessel, pulling push rod and soft piston, blood is drawn in the syringe, collect an amount of---behind 4 milliliters blood, transfer to needle point again, and according to actual needs the blood in the syringe is injected in the suitable silication test tube to be checked.Use the hemostix of said structure, operate more loaded down with trivial details, also must be equipped with clean, aseptic silication test tube in addition, but, by each health service unit come to test tube carry out disinfection, sterilization and silicidation are trouble very, not only treatment effect is undesirable, makes result of laboratory test produce deviation easily, and increased the workload of each medical institutions, very inconvenient during practical application.

Summary of the invention

This utility model will provide a kind of operation hemostix more simply and easily.

For achieving the above object, the technical solution adopted in the utility model is: described hemostix mainly comprises: syringe, the top upside of syringe is provided with the needle point seat, be provided with soft piston in the syringe, also be provided with the tip pipe in the inside top of syringe, the tip pipe is connected with the needle point seat; Also be connected with the silication test tube in soft piston lower end, and by in the inner chamber of the silication test tube of soft piston closes for meeting the vacuum state of national medical standard.

The further technical scheme of this utility model is: also offer aperture on the upper side wall of syringe, be provided with brake lining in the aperture.

This utility model further technical scheme is: on the basis of said structure, also be provided with the tubaeform bundle groove of leading on soft piston.

The utility model has the advantages that: use the hemostix of structure described in the utility model, the blood that collects can directly enter into silication test tube, more convenient operation, simpler; And by the production unit unification to test tube carry out disinfection, sterilization and silicidation just make things convenient for manyly, effect is also better; And, greatly reduce product cost owing to the parts such as push rod that saved in the original syringe.

Description of drawings

Fig. 1 is the structural representation of hemostix described in the utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are described in further detail.

As shown in Figure 1, hemostix described in the utility model mainly comprises: syringe 6, and the top upside of syringe 6 is provided with needle point seat 1, is provided with soft piston 5 in the syringe 6, also is provided with tip pipe 2 in the inside top of syringe 6, and tip pipe 2 is connected with needle point seat 1; Also be connected with silication test tube 7 in soft piston 5 lower ends; And by in the inner chamber of the silication test tube 7 of soft piston 5 sealings for meeting the vacuum state of national medical standard, vacuum state in the above-mentioned silication test tube 7 can be to make like this: at first soft piston 5 is installed in cleaning sterile---promptly meet on the silication test tube 7 of national medical standard, and then the inner chamber of silication test tube 7 carried out evacuation, how many big I of its vacuum decides according to concrete blood drawing, softer piston 5 and silication test tube 7 is encased in the syringe 6 together at last to get final product.

As shown in Figure 1, in the present embodiment, on the upper side wall of syringe 6, also offer aperture, be provided with brake lining 3 in the aperture; On soft piston 5, also be provided with tubaeform leading and prick groove 4.

The operation principle of hemostix described in the utility model is: at first install medical needle point on needle point seat 1, and needle point pricked into blood vessel, transfer to brake lining 3 then, promote silication test tube 7 again, make soft piston 5 gently in syringe 6---be the top pushing of syringe 6, till tip pipe 2 punctures and extend into soft piston 5 in the silication test tube 7, because the inner chamber of silication test tube 7 is the vacuum state that meets national medical standard, like this, under the effect of the negative pressure in silication test tube 7, blood just is inhaled in the silication test tube 7 by needle point seat 1 and tip pipe 3, an amount of when collecting---behind 4 milliliters blood, transfer to needle point again, and silication test tube 7 and soft piston 5 are pulled out from syringe 6 together, be put on the test tube rack to be checked.

On the upper side wall of syringe 6, offer aperture, and the effect that brake lining 3 is set in aperture is: when brake lining 3 is installed on the syringe 6, can stop that soft piston 5 moves to the top of syringe 6, prevent that issuable misoperation from puncturing soft piston 5, destroy the vacuum state in the silication test tube 7, be convenient to more install and transportation; And after having offered aperture on the upper side wall of syringe 6, when the brake lining 3 that takes out wherein, promote silication test tube 7 and soft piston 5 when move at the top of syringe 6, the air in the syringe 6 is run out of from this aperture, be convenient to more test tube 7 and soft piston 5 are pushed to the top of syringe 6.

The tubaeform effect of leading bundle groove 4 is set on soft piston 5 is: can guide tip pipe 2, make it more easily soft piston 5 to be punctured.

Use the hemostix of said structure, can allow the blood that collects directly enter into silication test tube 7, more convenient operation, simpler; And can by the production unit unification to test tube carry out disinfection, sterilization and silicidation, units such as health care buy the back and just can directly use, very convenient, and, make result of laboratory test also more accurate because soft piston 5 is retained on the test tube 7 before chemically examining always; And, greatly reduce product cost owing to the parts such as push rod that saved in the original syringe.
