Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to the blood sampling apparatus that a kind of hospital laboratory uses.
Background technology
Vacuum tube, since 1940's is invented, has adopted manual method blood sampling always.Through collecting the in-service evaluation of medical personnel, think that having following technology disadvantage has to be solved: 1, vacuum setting affects by atmospheric pressure, height above sea level difference in various places is difficult to correct accurately.Therefore blood sampling volume and etalon contrast and are difficult to reach standard.2, there is residual negative pressure larger because vacuum tube sets negative pressure, when actual acquisition specimen amount differs larger with the pressure difference value in vitro set, the last negative pressure that in vitro will remain varying degree after nurse pulls out pin in advance when replace tubes, cause outside the gas overflowing cell wall in hemocyte, cellularity is damaged.3, the thorn plug pin end of whether successful bidirectional needle of cannot judging to puncture is equipped with rubber sheath, without judging during blood back whether puncture is successfully more difficult after thrusting vein, and can only with the sensation of operator individual and experience.Traditional blood collection needle, when determining whether to puncture successfully by pumpback after syringe needle intravasation, and vacuum test tube does not solve by pumpback way, so need masterful technique and experience for when filling not good enough and minute blood vessel blood sampling.4, need bimanualness during manual replace tubes, can not free hand to fixing blood collection needles, during replace tubes, syringe needle moves and blood collection needles can occur deviates from EV accident and cause taking a blood sample unsuccessfully, causes doctor-patient dispute.5, need nurse to mix specimen by hand after blood sampling, just must mix after the unified blood sampling of multitube blood sampling, the patient being now in hypercoagulability there occurs micro-blood coagulation.Half-hearted mixing can make defective specimen increase, and makes assay produce error.6, the security risk vacuum tube existing in backflow of blood body is when after negative pressure exhausts, in vitro atmospheric pressure is higher than venous pressure, and external existing case report has the risk in backflow of blood body.Now external test tube is all sterilizing, is domesticly also promoting the use of sterilizing vacuum tube gradually, but but adds manufacturing cost.7, the negative pressure curve of vacuum test tube be sliding board-type in continuous decline state, at the end of closing on blood sampling, negative-pressure sucking weakens the patient such as high blood viscosity, hyperlipidemia can be caused to take out less than master scale.In order to address these problems, can overcome just need to invent a kind of automatization vacuum tube blood sampling apparatus.Adopt and automatically fill pin, automatically sting plug, automatic replace tubes, automatic ration, automatically discharge negative pressure, the method for automatic mixing realizes.At present, come out there are no pertinent literature or product.
