Abstract
The utility model discloses a medical microdose blood collection tube. The blood collection tube comprises an air bag, a cannula and a suction tube, wherein the air bag adopts elastic rubber material, the cannula which can also be taken as a handle is connected at one end of the air bag, the cannula is movably connected with the suction tube through a connecting piece, the suction tube adopts a capillary tube, and on which scale is indicated. Because the cannula and the suction tube are movably connected through the connecting piece, the suction pipe can be replaced in time and is disposable, the cannula with the air bag can be reused times and again, therefore, not only the cost is reduced, but also the cross infection is prevented.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments of the usefulness of taking a blood sample, especially a kind of take a blood sample slightly blood taking instrument of usefulness of end of doing when being suitable for blood count.
Background technology
At present, take a blood sample slightly and mainly utilize the Li Shi suction pipe in the end clinically, pinch the mode of Capsule carries out with hands, there is following problem in this blood sampling mode: the one, there is the problem of cross infection, this is that the reuse suction pipe is collected blood sample because blood sampling site is broken with pinprick, shifts and stores, cause cross infection easily, and troublesome poeration; The 2nd, glass blood sampling suction pipe, glass surface easily triggers clotting mechanism, causes the platelet distortion, influences result of laboratory test, and the while is fragile, cost is high, and disposable use is had any problem, and is difficult to reach a people one pipe, one time one disinfectant requirement.
Summary of the invention
The purpose of this utility model is exactly at the existing end above problem that the blood taking instrument of usefulness exists of taking a blood sample slightly, a kind of medical trace blood pipe is provided, it has avoids cross infection, anti-hemostasis-coagulation phenomenon to produce in blood collection procedure, and advantage simple in structure, that cost is low.
The purpose of this utility model is to realize like this, this trace blood pipe comprises air bag, sleeve pipe, suction pipe, described air bag is the rubber-like elastomeric material, described air bag one end is connecting the sleeve pipe of double as handle, described sleeve pipe flexibly connects by a connector and suction pipe, and described suction pipe is a capillary tube, has this degree on it, the capacity of suction pipe is pre-determined, utilizes the capillary imbibition principle to realize that automatic control quantitatively takes a blood sample.
The beneficial effects of the utility model are: because sleeve pipe and suction pipe are to flexibly connect by connector, can in time change suction pipe, accomplish a people one pipe, the sleeve pipe of band air bag can be repeatedly used, and has promptly reduced cost, has prevented cross infection again.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a sketch map of the present utility model
Among the figure: 1, air bag 2, sleeve pipe 3, suction pipe 4, connector 5, scale
The specific embodiment
As shown in Figure 1, this trace blood pipe comprises air bag 1, sleeve pipe handle 2, suction pipe 3, air bag 1 is the rubber-like elastomeric material, air bag 1 one ends are connecting the sleeve pipe 2 of double as handle, sleeve pipe 2 flexibly connects by a connector 4 and suction pipe 3, and suction pipe 3 is a capillary tube, has this degree 5 on it, the capacity of suction pipe 3 is pre-determined, utilizes the capillary imbibition principle to realize that automatic control quantitatively takes a blood sample.Because sleeve pipe 2 is to flexibly connect by connector 4 with suction pipe 3, can in time change suction pipe, accomplishes a people one pipe, the sleeve pipe of band air bag can be repeatedly used, and has promptly reduced cost, has prevented cross infection again.
