clinical laboratory's intelligence indicates blood inspection device
Technical Field
the invention relates to a device for clinical laboratory examination, relates to a finger blood examination device, and particularly relates to an intelligent finger blood examination device for clinical laboratory examination.
background
Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, cytological tests for bone marrow, blood grouping and cross matching tests. Hematological signs of common hematological disorders can be detected.
Blood biochemistry is a plurality of projects, namely a complete set of projects which can be made by a biochemical chamber. Generally, the liver function is an index for diagnosing main systems of a body, for example, liver function is an index for examining the digestive system of liver and gall, which can indicate the diseases, and kidney function is an index for examining kidney and urinary system. Myocardial enzymes are systems that examine heart function. The ions are potassium, sodium, chloride and calcium in blood, and many blood routinely comprises 20 items, but the main items are four items: white blood cells, red blood cells, platelets, hemoglobin.
the current finger blood test which is less used is only limited to the test of items such as infants, blood sugar and the like, firstly, the finger blood is easy to bring interference, but the finger blood collection is slow, and the collection amount is not easy to control. But since the damage of venous blood sampling is larger than finger blood examination, the actual finger blood examination should be more widely used.
application No.: 201711204881.9 discloses a clinical laboratory blood analyzer, its structure includes blood analyzer, a housing, an operation panel, a card insertion device, an invoice inlet, a side case, the accessible sets up the recess that has the test tube hole, be convenient for place the blood test tube, increased the convenience, through setting up the document holder that has the casing, be convenient for carry out the buckle to the detection document of clinical laboratory and accomodate, be convenient for observe the record, have the operation panel of a card insertion device through the setting, be convenient for directly read data in the past. But it is only a function that integrates the functions of the existing conventional blood analyzer without intelligent examination.
Application No.: 201711291380.9 discloses a clinical laboratory blood sampling device, including bottom plate, installation component, hose one and extraction subassembly, reached and improved the purpose that the vacuum tube stability and carry out blood sample collection in proper order, still realized carrying out the function that supports medical personnel hand at blood collection in-process, reduced the work degree, its adopts the vacuum to carry out the negative pressure blood sampling, but not the collection indicates blood, and the injury nature of venous blood sampling is higher than greatly indicates blood.
Application No.: 201410788567X provides a clinical laboratory is with multi-functional intelligent blood sampling system, two-way aseptic syringe needle is connected with the vacuum blood sampling bag, realized from the intelligent control who takes a blood sample to seal, through swaing the device during the blood sampling, blood coagulation has been avoided, prevent further blood drawing by the controller when the volume of taking a blood sample reaches established value, the vacuum blood sampling bag is sealed to rethread high frequency heat seal ware, thereby accomplish the intelligent control of whole blood sampling process, integrate a plurality of functions on a blood sampling system, it provides intelligent control, but it does not propose new blood sampling method, the blood sampling still needs the manual work to prick the needle.
In view of the above, it would be desirable to provide an intelligent, portable lancing device for clinical use that does not require the control of a professional.
