Abstract
The utility model belongs to the technical field of medical inspection equipment, more specifically relates to a disposable automatic hemospast used for taking venous blood samples. When the utility model is used, the quality of blood samples is enhanced, the check errors caused by hemolysis and change of blood constituents are avoided, the number of pieces need disinfecting is reduced, and the chance of pollution is lowered. The utility model is composed of a needle, a needle holder, and a test tube. The utility model is characterized in that a sliding needle holder is assembled at the internal space of the needle holder, a press plate is arranged at the lower end of the sliding needle holder, an internal needle inserted into the test tube is installed under the press plate, the lower end of the needle holder is inserted into a rubber plug, and the rubber plug is inserted into the test tube.
Description
This utility model belongs to medical test equipment technical field, specifically is used for the disposable automatic hemospast of taking the venous blood specimen.
Check in the past is to extract with glass syringe with blood preparation, in recent years because of of the glass syringe approach cross infection of viruses such as hepatitis by using repeatedly, replace and use disposable plastic injector instead, but also exist: 1, cost is too high, price is about one yuan one pair, only can use in the part large hospital.2, there are the spin friction that syringe needle and nipple junction surface produce blood equally in plastic injector blood drawing process and glass syringe.Nook closing member is the friction of air, friction during injecting tube etc. and cause haemolysis and emergent gas composition to cause the error of assay.3, when taking original blood drawing method, the essential equipment such as needle tubing, test tube, pipe close that use have increased the sterilization number of packages, have increased opportunities for contamination.
The purpose of this utility model is: improve the blood preparation quality, avoid haemolysis and blood component to change the testing error that is caused, reduce the sterilization number of packages, reduce opportunities for contamination, handled easily is simplified the blood sampling program.
This utility model technical solution:
A kind of automatic hemospast of being made up of syringe needle, needle stand, needle tubing is characterized in that needle stand heart space is equipped with the slip needle stand, in slip needle stand lower end pressing plate is arranged, and the interior pin that thrusts test tube is housed under the pressing plate, and insert in the rubber stopper needle stand lower end, and rubber stopper inserts in vitro.
This utility model advantage:1, taking out the anticoagulant that to put into various uses before true in advance, venous blood is directly entered behind the test tube promptly and the anticoagulant mixing; Blood does not contact with outside air when 2, using this hemospast blood drawing, has prevented the variation and the outside contamination of blood component; 3 blood sampling backs are dialled and removed needle guard, subsidiary kilowatt of plug of guide pin promptly is the teat glass of a, can directly deliver to the sterilizing room operation of testing, and the design's main part is teat glass and pipe close, and all recyclable reuse of device that these do not go up human body has reduced use cost; 4, easy to operate, simplified the program of work for inspection.
Fig. 1 is this utility model structural representation.
Fig. 2 is a slip needle stand enlarged diagram among Fig. 1.
Below in conjunction with accompanying drawing this utility model is further described:
Select the consistent hard glass test tube 7 of internal diameter for use, a groove is arranged in the test tube rubber stopper 6, adorn needle stand 2 lower ends fully, needle stand 2 inner chambers have hand slip needle stand 3, after syringe needle 1 penetrates blood vessel, see that in time pressing pressing plate 4 when in the needle stand blood back being arranged descends, both sides, pressing plate 4 lower end are gapped, pin 5 falls to penetrating rubber stopper 6 in being equipped with, because of in the test tube 7 negative pressure being arranged, blood is flowed in the test tube 7 fast, after blood drawing finishes, pull out the needle stand part, the sealing test tube that stays the band rubber stopper send to be tested.
Have anticoagulant (blood plasma), coagulant (serum) in the test tube 7.
