Abstract
The utility model discloses a blood collecting device which integrates blood collection and blood separation, belonging to the technical field of medical instruments. The device mainly comprises a blood collecting tube (3) and a test tube (6), and is characterized in that the upper end of the blood sample tube (3) is sealed with a sealing cover (2), the interior port of lower opening (5) of the blood collecting tube (3) is fixed with a filter membrane (4), and the blood collecting tube (3) is connected hermetically with the test tube (6) via the lower opening (5). The utility model has the advantages of no use of syringe and sucker for blood collection, low cost, no cross contamination during the blood serum separation, and high work quality.
Description
Affiliated technical field
This utility model relates to a kind of sharp blood sampling and the blood-taking device that separates one, belongs to medical instruments field.
Background technology
Serum process before the hemanalysis of extensively taking at present is centrifugal analysis again behind the injecting tube extraction serum after taking a blood sample with syringe.The employed apparatus of such operating process is more relatively, and blood sample shift and operating process in careless slightlyly will cause cross-contamination, have a strong impact on assay.
Summary of the invention
Main purpose of the present utility model is that a kind of hemostix of the separation one of taking a blood sample, total closed type are operated and stopped to pollute, and be simultaneously simple in structure, easy to operate.
Technical solution of the present utility model is as follows:
A kind of blood sampling separated the hemostix of one, mainly form by blood taking tube 3 and test tube 6, the upper end that is characterized in blood taking tube 3 is sealed by seal closure 2, and the internal orifice place of blood taking tube 3 lower ending openings 5 is fixed with a filter membrane 4, and blood taking tube 3 carries out airtight the connection by its lower ending opening 5 with test tube 6.
Wherein the lower ending opening 5 of blood taking tube 3 can be made into screw-socket, and carries out airtight the connection with the opening of test tube 6 by screw.Filter membrane 4 is fixed by annular trim ring.
Taking to operate hemostix for raising is airtight interior vacuum tube.
The good effect of this design is, has saved apparatuses such as syringe, suction nozzle in the blood drawing process, reduces cost.Avoid the cross-contamination in the serum transfers process simultaneously, improved work quality.
Description of drawings
Fig. 1 is the structural representation of a kind of hemostix of the separation one of taking a blood sample among this utility model embodiment.
The specific embodiment: preferred implementation is as follows.
Embodiment: a kind of blood sampling separated the hemostix of one, mainly form by blood taking tube 3 and test tube 6, the upper end that is characterized in blood taking tube 3 is sealed by seal closure 2, the center of seal closure 2 is recessed rubber closure 1, the internal orifice place of blood taking tube 3 lower ending openings 5 is fixed with a filter membrane 4, and blood taking tube 3 carries out airtight the connection by its lower ending opening 5 with test tube 6.Wherein the lower ending opening 5 of blood taking tube 3 is a screw-socket, and carries out airtight the connection with the opening of test tube 6 by screw.Filter membrane 4 is glass fiber filter (allowing the granule of diameter＜2um to pass through), fixes by annular trim ring, and hemostix is airtight interior vacuum tube.
During operation, after the infusion needle of at first getting two ends band pin thrusts skin, in the other end insertion tube of band syringe needle, because the effect of negative pressure and the effect of blood pressure, blood flows in the hemostix voluntarily, and it is centrifugal to treat to put into centrifuge behind the blood coagulation, and the serum part enters test tube 6 by filter membrane 4, the screw of outwarding winding makes invisible spectro serum directly put into automatic biochemical analyzer and measures.
This utility model has been saved apparatuses such as syringe, suction nozzle in the blood drawing process, reduces cost, and has avoided the cross-contamination in the serum transfers process simultaneously, has improved work quality.
