Abstract

The utility model relates to a novel blood taker which is composed of a push button, a pressure lever, a pumping lever, a casing, a suction tube, a needle, and a transparent plastic casing tube which can be assembled and disassembled. A big and a small two compression springs are arranged between the suction tube and the pumping lever, and the big compression spring is sheathed on the small compression spring. The length differences of the two springs are utilized to accurately control the blood taking quantity. Because the plastic casing tube used for blood taking can be replaced, one casing tube is only used by one person, and the cross infection is avoided. The utility model has the advantages of reasonable design, convenient operation, and low cost. The utility model is suitable for blood taking for blood routine examinations in sanitary departments.

Description

Blood taker

The utility model relates to a kind of hand-operated tools of health care mechanical field.

Medical department is done the routine blood test chemical examination, adopts the hematochrome pipette method to take a blood sample usually, and the instrument that this method is used is grasped the amount of sucking blood by experience, and is wayward.In addition, everybody reuses a branched pipette, has increased the weight of cleaning, disinfection greatly, and, also easily cause cross infection.Recently occur again though it can accomplish a people one arm, having prevented cross infection with the blood sampling of capillary tube glass, the amount of sucking blood is wayward equally, and the cost height.

The purpose of this utility model is that a kind of novel hemostix with low cost will be provided, and it both can accurately control blood sampling volume, can accomplish a people one arm again, effectively prevents cross infection.

The purpose of this utility model is achieved in that at suction tube, takes out between the masthead lid, and two compressions of size spring of suit is housed.The thin end of taking out bar stretches in the hole of suction tube, when pressing button compression big spring, make and take out the thin end of bar and further go deep in the suction tube hole, air in the suction tube hole is also just discharged gradually like this, after taking out masthead lid and touching the vertical spring compressor of little spring,, will make big or small two springs pressurized simultaneously if when continuing to press button again, thereby the resistance multiplication, feel is very obvious.Promptly stop the button supercharging this moment.When loosening button, because the effect of spring.To take out masthead and return, produce negative pressure in the suction tube hole, blood will be drawn onto in the plastic tube on the syringe needle, like this because to the control of the difference of big little spring length, thereby also just controlled blood sampling volume how much.Lucite pipe on the syringe needle is removably.After having adopted a people's blood sample.Can unload, other adorns a new casing, adopts second people's blood sample again, thereby has realized a people one arm, prevents cross infection effectively.

This utility model is simple in structure, and is easy to use, saves time, laborsaving, and blood sampling volume is controlled easily, and row's blood sample can fully have been arranged again.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the sketch map of novel hemostix.

Novel hemostix shown in Figure 1 is by button (1), overcoat (5), take out bar (6), big spring (8), little spring (9), suction tube (10), syringe needle (11) and sleeve pipe (12) constitutes.Big little spring is in suction tube (10) and takes out between the masthead lid (4), at the little spring end spring compressor (7) is arranged, the thin end of taking out bar (4) passes through from its hole, and insert in the hole of suction tube (10), the depression bar (2) of button (1) lower end passes block (3) and contacts with taking out masthead lid (4), and is subjected to the outside thrust of spring always.

Hemostix shown in Figure 1 is the free state that is in inoperative, when using, press button (1), depression bar (2) promptly promotes to take out masthead lid (4) and compression big spring (8), at this moment taking out the thin end of bar gos deep in the hole of suction tube (1) more, when taking out masthead lid (4) and run into spring compressor (7), owing to be subjected to the little spring effect again, resistance obviously strengthens, promptly stop this moment button is continued pressurization, and after making sleeve pipe (12) contact the blood that to adopt, loosen button, at this moment, because the effect of spring, take out bar and depression bar reposition, just produce negative pressure in the suction tube hole, thereby with in the quantitative blood scution bush, during row's blood, again press button and spring compressor (7) and spring (9) are also depressed a segment distance, make the air of taking out in bar (6) compressing suction tube and the syringe needle hole, the blood in the sleeve pipe (12) is fully discharged.After finishing a people blood-sample withdrawal work, bobbin taken off throw away, change new casing again, can carry out blood sampling work to second people again.

Claims

1, a kind of by button, depression bar, take out the novel hemostix that bar, sleeve pipe, suction tube and syringe needle are formed, it is characterized in that: suction tube and take out between the masthead lid compression spring is housed is with removably bobbin on the syringe needle of suction tube front end.

2, according to the described novel hemostix of claim 1, it is characterized in that: said compression spring is by two of sizes, and suit is formed, and big spring length is greater than little spring, and both differences and required blood sampling volume are complementary.

3, according to the described novel hemostix of claim 1, it is characterized in that: the said sleeve pipe that loads and unloads, make with transparent plastic.
