Abstract
The utility model relates to a blood sampler whose glass test tube can be used as a needle cylinder and a blood storage container, the inner cavity of the needle cylinder is pumped vacuum, the orifice of the blood transfusion tube which is communicated with the inner cavity of the needle cylinder is sealed by a rubber cap, and the needle tube is connected with a needle tube which is provided with a cap with a thorn. When the rubber cap is punctured by the needle tube which is provided with a cap with a thorn, the needle tube which is provided with a cap with a thorn is extended in the blood transfusion tube, and the blood can be sampled rapidly. The utility model has the advantages of simple structure low cost, convenient operation, and fast blood sampling speed under the vacuum condition. A fine needle tube can be adopted to relieve the needling pains of patients, the glass test tube is pollution-free, and is consistent with the sanitary requirements of blood sampling.
Description
This utility model is the chemical examination and haemospasia device about blood testing blood drawing usefulness, and particularly disposable chemical examination and haemospasia device belongs to medical apparatus and instruments.
Disposable chemical examination and haemospasia device can prevent the cross infection in the blood draw process effectively, thereby more and more is subjected to the attention of medical department.It is syringe that existing disposable chemical examination and haemospasia device adopts the flexible plastic container of hollow mostly, by making the negative pressure extracting blood that produces in its extruding recuperation, because the container recuperation is slow, negative pressure is very little, blood drawing speed is slow excessively, though the disposable hemospast of plunger type or other structure is also arranged, most complex structure, cost is higher.
The purpose of this utility model provides that a kind of blood drawing speed is fast, simple in structure, and cost is low, disposable chemical examination and haemospasia device easy to use.
This utility model chemical examination and haemospasia device is made up of teat glass formula syringe and needle tubing, the blood that needle tubing extracts is introduced in the syringe by emissary vein, the syringe inner chamber is evacuated by exhaust branch pipe, the front end mouth of pipe of the emissary vein that communicates with it seals with rubber cap, the rear end of Syringe needle for taking samples of blood 9 links to each other with a thorn hatpin pipe 8, both can fuse into the double end needle tubing, also can link to each other by plastic flexible pipe, be connected by latex tubing between thorn hatpin pipe and the emissary vein, the exhaust branch pipe that links to each other with vacuum pump can be located on the syringe and also can be located on the emissary vein, after the extracting vacuum, that this seal of tube is stand-by.Puncture rubber cap and stretch in the emissary vein as long as will sting hatpin during use, blood is promptly automatically rapidly in the suction syringe.
Adopt this utility model vacuum chemical examination hemospast because blood extracts under bigger suction function, can adopt thinner needle tubing and still keep the speed of drawing blood faster, easy to use, and the misery can alleviate patient's inserting needle the time, glass syringe double as blood storage container, pollution-free to blood, this hemospast is simple in structure, cost is low, is fit to disposable use.
Below in conjunction with description of drawings two embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model, and that represent among the figure is the embodiment that thorn hatpin pipe and Syringe needle for taking samples of blood fuse.
That Fig. 2 represents is thorn hatpin pipe and Syringe needle for taking samples of blood embodiment disconnected from each other.
Among Fig. 1, teat glass 1 double as syringe and blood storage container, the mouth of pipe of test tube is sealed by nontoxic rubber closure 2, one end of emissary vein 3 passes rubber closure 2 and stretches in the test tube 1, the other end is sealed by rubber cap 4, emissary vein 3 has the arm 8 of a bypass to be the vacuum pump connection tube, after the extracting vacuum with ferrule, thorn hatpin pipe 9 fuses into the double end needle tubing with Syringe needle for taking samples of blood 10, the needle tubing external fixation is held up needle stand 6, one end of latex tubing 5 is socketed on outside the emissary vein, and the other end is socketed on holds up needle stand 6, and Syringe needle for taking samples of blood 10 outer being with are protected needle guard 7.
During use, take out and protect needle guard 7, Syringe needle for taking samples of blood is thrust vein blood vessel, the hand steered needle stand 6 of holding up, test tube 1 is advanced to the needle tubing direction, and latex tubing 5 is compressed, and makes the mouth of pipe of emissary vein push needle tubing 9 to, thorn hatpin 9 promptly punctures rubber cap and stretches in the emissary vein, and blood promptly flows in vitro rapidly automatically under vacuum action.
Among Fig. 2, thorn hatpin pipe 9 is disconnected from each other with Syringe needle for taking samples of blood 9, and links to each other by plastic flexible pipe 11.Present embodiment is convenient to the vein haemospasia at positions such as cervical region.
Be connected with exhaust branch pipe with vacuum pump when this utility model hemospast prepares, make the vacuum of syringe inner chamber be evacuated to 1 * 10
-3MmHg, with lighter check, in have the purple fluorescent to occur.
