Abstract
The utility model relates to a test tube type device for a blood sampler, which is mainly composed of a puncture pinhead (1), a needle handle (2), conduits (3) and a blood sampling bag (4), wherein, the test tube type blood sampling bag (4), the puncture pinhead (1) and conduits (3) are connected into one body, and the connection structure leads the structure of the blood sampling device to be more simple and reasonable. The working procedure of nurses in blood sampling time is reduced, and the whole blood sampling procedure is carried out in a closed environment. Because the utility model can serve as a test tube for examination when the ends of the conduits (3) are cut off after the blood sampling, and the utility model has the advantages of material saving, low cost, and very convenient use.
Description
This utility model relates to a kind of blood-taking device, particularly a kind of test tube formula hemostix.
At present, medical treatment blood sampling check is normally thrust blood vessel with desired blood with entry needle in our hospital, earlier with the desired blood inhalation syringe, again the blood injecting tube is tested, it is cumbersome to operate, the blood collection procedure complexity is easy to pollute, in addition because the cost of syringe is higher, so also caused very big waste.
The purpose of this utility model is that a kind of principle of utilizing intravascular pressure to make the blood outflow will be provided, and is simple and reasonable, is difficult for polluting, and can gather the test tube formula hemostix of check desired blood equally without syringe.
The purpose of this utility model is to realize like this, this test tube formula hemostix is mainly by piercing needle, needle handle, conduit, the blood-retention capsule is communicated with formation, piercing needle and needle handle are connected an end of conduit, and the other end of conduit is connected with the blood-retention capsule, have scale on the surface of blood-retention capsule, conduit and blood-retention capsule are by transparent and have certain elastic material and constitute, be subjected to the external force deformable, can restore to the original state naturally by himself elasticity, the blood-retention capsule can be made into two kinds of test tube shape and thin pocket type shapes.
This utility model is owing to adopted the blood sampling capsule and the syringe needle of test tube formula, the structure that conduit fuses, make the structure advantages of simple more of blood-taking device, reduced the working procedure of nurse when blood sampling, whole blood collection procedure is carried out antifouling property in enclosed environment good, when preserving as need strange land check or long period, because conduit part is easy to the heat seal sealing, be easy to carry, cutting off catheter end in addition after the blood sampling promptly can be used as test tube and tests, the material of saving has reduced cost, and it is also convenient especially to use.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is test tube formula hemostix structural representation.
Describe specific implementation process of the present utility model in detail below in conjunction with accompanying drawing:
This test tube formula hemostix is mainly by piercing needle 1, needle handle 2, conduit 3, blood-retention capsule 4 is communicated with formation, piercing needle 1 and needle handle 2 are connected an end of conduit 3, the other end of conduit 3 is connected with blood-retention capsule 4, have scale 5 on the surface of blood-retention capsule 4, conduit 3 and blood-retention capsule 4 are by transparent and have certain elastic material and constitute, and are subjected to the external force deformable, elasticity by himself can restore to the original state naturally, and blood-retention capsule 4 can be made into two kinds of test tube shape and thin pocket type shapes.
Embodiment 1, when adopting the blood sampling of test tube formula hemostix, earlier blood-retention capsule 4 is curled, after getting rid of the gas in the capsule 4, again conduit 3 opisthotonos are pressed on after needle handle 2 places make conduit 3 chambeies sealings obstructed, unclamp the blood-retention capsule 4 that has curled, when hand-held needle handle 2 thrusts blood vessel with syringe needle 1 (as seen catheter proximal end has blood to enter), the invagination of conduit 3 is unclamped, make conduit 3 chambeies sealed become path, vessel inner blood since the negative pressure of intravascular pressure and blood-retention capsule 4 by piercing needle 1, enter in the blood-retention capsule 4 through needle handle 2 path conduits, when blood-retention capsule 4 is placed upright position in conjunction with capsule 4 high scales as can be known blood volume what, after blood sampling finishes, the nose end that has of blood-retention capsule 4 is cut off, can work as the test tube use.
During use, when piercing needle 1 thrusts blood vessel, because intravascular pressure, make blood enter blood-retention capsule 4 by piercing needle 1, needle handle 2, conduit 3, make blood-retention capsule 4 be entered blood pressure and the expansion blood-retention, after blood sampling finishes, the blood in the blood-retention capsule 4 is clamp-oned in the test tube and can be tested.
Claims (2)
1, a kind of test tube formula hemostix, this test tube formula hemostix is mainly by piercing needle (1), needle handle (2), conduit (3), blood-retention capsule (4) is communicated with formation, it is characterized in that: piercing needle (1) and needle handle (2) are connected an end of conduit (3), the other end of conduit (3) is connected with blood-retention capsule (4), have scale (5) on the surface of blood-retention capsule (4), conduit (3) and blood-retention capsule (4) are by transparent and have certain elastic material and constitute;
2, a kind of test tube formula hemostix according to claim 1 is characterized in that: blood-retention capsule (4) can be made into test tube formula and two kinds of shapes of thin pocket type.
