Description
Technical field:
This utility model relates to medical instruments field, specifically a kind of disposable blood taking device that is used for hospital's blood sampling.
Background technology:
Now, the blood taking needle that hospital and blood station collection blood are used uses disposable syringe usually, be to constitute by syringe needle, needle tubing, piston, push rod, one end of syringe needle is connected with the needle tubing upper end, piston is connected with push rod, and be sleeved in the needle tubing, piston and needle interior wall match, and the propelling by push rod or extract out slides up and down at needle interior wall, its deficiency is: the medical worker in use, the one, gathered blood sample after, with the blood sample in the syringe be expelled to the chemical examination usefulness in vitro, the chemical examination of again test tube being taken away causes the cost waste; The 2nd, it is oversize that push rod is pulled out, and touches easily, causes the blood of collection to spill contaminated environment easily; The 3rd, there is not scale on the test tube wall, the medical worker gathers blood with sensation, causes the blood waste easily.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and reduces cost, quantitative collection, is difficult for touching, reducing the disposable blood taking device of pollution.
This utility model can reach by following measure:
A kind of disposable blood taking device, be to constitute, it is characterized in that being provided with pinhead sleeve that one end is sleeved on the needle tubing in the upper end of needle tubing by syringe needle, needle tubing, piston, push rod, the other end is connected with syringe needle, bottom, the lower end of needle tubing is provided with circular hole, and the diameter of circular hole is less than the internal diameter of needle tubing, is provided with groove in the upper end of push rod or with the junction of piston, be convenient to fractureing of push rod, test tube wall is provided with scale, and the medical worker can reduce the blood waste according to scale quantitative collection blood.
This utility model is by adopting said structure, have easy to operate, reduce cost, reduce advantage such as pollution.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Reference numeral: syringe needle 1, pinhead sleeve 2, needle tubing 3, piston 4, push rod 5, scale 6, groove 7.
The specific embodiment:
Below in conjunction with Fig. 1 this utility model is further described:
A kind of disposable blood taking device, be by syringe needle 1, needle tubing 3, piston 4, push rod 5 constitutes, its annexation is same as the prior art, this does not give unnecessary details, it is characterized in that being provided with pinhead sleeve 2 in the upper end of needle tubing 3, one end is sleeved on the needle tubing 3, the other end is connected with syringe needle 1, the bottom, lower end of needle tubing 3 is provided with circular hole, the diameter of circular hole is less than the internal diameter of needle tubing, be provided with groove 7 in the upper end of push rod 5 or with the junction of piston 4, be convenient to fractureing of push rod 5, needle tubing 3 walls are provided with scale 6, during use, the medical worker pricks disposable blood taking device in blood count person's body, with middle finger and forefinger clamping needle tubing 3, blood is drawn in the needle tubing 3, can be according to scale 6 quantitative collection blood, reduce the blood waste, collection finishes, and push rod 5 is pulled out needle tubing 3, when the groove on the push rod 57 is just in time mutually concordant with needle tubing 3 bottoms, hold push rod 5 firmly, cause push rod 5 to fracture, pull out syringe needle 1 again to a side, turn round down pinhead sleeve, needle tubing as test tube, can directly be inspected by ready samples needle tubing 3, and this utility model is owing to adopt said structure, reduce trouble to the medical worker, have easy to operately, environment is clean and tidy, and advantage such as reduce cost.
