Description
Technical field the present invention relates to a kind of medical apparatus and instruments, especially the venous blood collection utensil used of hospital's blood test.
The vacuum blood collection system is as totally-enclosed blood sampling system, and greatly amplitude improves the blood sample quality, laboratory quality control before promoting to analyze.Than medical workers' such as conventional syringe blood sampling better protection blood sampling teacher, docimaster safety, avoid the haematogenous cross infection simultaneously.Nowadays, worldwide, the vacuum blood collection system is the main flow of blood specimen collection system, China recent years has been carried out the introduction and the exploitation of vacuum blood collection system, Ministry of Public Health had been issued " collection and the processing of WS/T 225-2002 clinical chemistry test blood preparation " and " WS/T 224-2002 vacuum test tube and additive thereof " two health industry standards in 2002, had stipulated that clinical chemistry test collects blood preparation and must use the disposal vacuum blood taking tube.The vacuum blood collection system of band safety head has shortened blood sampling time because of it has safe and reliable advantage, has reduced the doctor and patient infection chance, has improved quality inspection.But in the clinical manipulation process, found some problems,, the present invention proposes better technology solution by analyzing and summing up prevention methods.Under the advantage situation that keeps the vacuum blood collection system, overcome its existing insoluble disadvantage.
The present venous blood collection of background technology is technical operation more common in the clinical nursing activity.Past prolongs always uses the blood collection needle method, both wastes time and energy, and blood sample pollutes again in the tuberculosis process easily, and hemocyte can suffer to destroy and cause haemolysis, influences the accuracy of assay.The thirties in 20th century, U.S. company BD has been invented vacuum blood drawing technique.Most of developed countries generally use the vacuum blood collection system, thereby the vacuum blood collection method is used widely in the clinical vein puncture.It is the change of a venipuncture technology, has remedied many deficiencies of traditional disposable syringe blood sampling.But adopt vacuum blood collection method big time saver, avoided blood sample pollution originally, guaranteed the accurate of blood sampling volume.But it is not a very perfect technology yet, and congenital defect and some problems in the operation of still having many these technology to exist need to solve.Particular problem is as follows: (1) haemolysis is because the interior negative pressure of vacuum tube is bigger, and blood sampling is initial, and blood inflow pipe low speed degree is fast, and erythrocyte clashes into mutually to cause and breaks, and foam increases, and easily causes haemolysis.(2) there is residual negative pressure because ordinary vacuum tube uses extensively, it is bigger to set negative pressure, if the collect specimen amount is bigger with the pressure difference value of in vitro setting, last when replace tubes in vitro still can residual bigger negative pressure, the gas that causes being dissolved in the blood overflows, cause the erythrocyte swelling fracture, cause haemolysis.In addition, remaining negative pressure also can reduce the speed of blood coagulation, and blood clot retraction is slowed down.(3) leak blood and cause the loosening or syringe needle of the two-way blood taking needle blood sampling of blood contamination pipe end latex sheath to sting out the latex sheath, cause two-way blood taking needle poorly sealed.During venipuncture, blood spills along the pipe close puncture needle end or the seam of two-way blood taking needle.Rubber stopper thickness is big, Ci Sai and pull out pin effort, and syringe needle is bonding can to cause syringe needle to deviate from when not firm.(4) can't judge whether successful bidirectional needle is judged the whether successful difficulty that punctures when puncturing no blood back in puncture, can only can judge whether puncture is successful with having blood to flow into behind operator's sensation, experience or the connection vacuum tube.If but when puncture connect vacuum tube, puncture failure causes the vacuum tube negative pressure to reduce causing waste again.Traditional blood collection needle can determine whether to puncture successfully by pumpback, and vacuum test tube can not solve by the pumpback way behind the syringe needle intravasation, so difficult during for full not good enough and minute blood vessel blood sampling.Do not seal when (5) in vitro having the not enough vacuum test tube of negative pressure or negative pressure, can not become flexible the pipe lid during use in case vacuum expendable pattern by manufacturer production.But have or not vacuum with the naked eye not discern, also can not first detector tube before clinical practice in vacuum state puncture successfully but adopt situation not hemorrhage or that blood volume is not enough after thrusting blood taking tube to get rid of useless pipe, therefore to exist.(6) blood sampling volume is can not the Autonomous Control blood preparation too much or very fewly the phenomenon that blood does not coagulate in blood coagulation in the anticoagulant tube, the coagulant pipe will take place take place.The minority blood taking tube exists quality problems to cause negative pressure deficiency or too high in the blood taking tube unavoidably.(7) test tube manufacturing cost height is in order to keep negative pressure for a long time, must good chlorinated butyl plug and PET test tube and the medical grade teat glass of service property (quality), can not use the test tube of soft material, cause cost to improve, increase the weight of patient's financial burden, be not suitable for the requirement of the overall situation of current medical reform.(8) also have the shortcoming of a fatal anthropic factor: vacuum test tube is not got rid of some people and is deliberately destroyed in process of production or after being sold to hospital, bleeds off the negative pressure in the vacuum tube, and manufacturing contingences causes the complaint of user to producer's quality problems.The present vacuum state of technology in still can't test tubes, this type of problem can't solve.
In order to overcome the problems referred to above, the inventor had once applied for " airtight negative-pressure automatic hemostix device " patent No. 99214075.7 " totally-enclosed negative pressure hemostix " patent No. 95245460 " airtight negative-pressure automatic hemostix device " number of patent application 98112817[publication number]: 1225809.It has kept the advantage of vacuum blood collector, has overcome its shortcoming, but needs to solve through still having problems after implementing: 1, manual multitube replace tubes inconvenient operation is loaded down with trivial details.2, can not soft, hard tube dual-purpose, aspirate soft test tube and cause tube wall to subside.3, machine noise is big.4, can not original position mixing anticoagulated blood after blood sampling is finished.5, the volume of instrument is bigger, can not be rationally all function layouts in narrow and small tool housing.
