The invention relates to a blood sampling auxiliary device for separating a serum sample from whole blood, at least comprising: a blood sampling tube body for storing collected liquids; a blood sampling tube cover assembled on the blood sampling tube body; and a blood sampling and subpackaging assembly capable of controllably conveying a liquid in the blood sampling tube body out of the blood sampling tube body in the mode that one end of the blood sampling and subpackaging assembly is connected with the blood sampling tube cover in a matched mode. The blood sampling and subpackaging assemblyis configured to output a liquid stored in the blood sampling tube body by times in a specified amount in a manner that the gas from the outside of the blood sampling tube body through the blood sampling tube cover does not pass through the liquid stored in the blood sampling tube body.

The invention relates to a method for creating an animal pharmacokinetic model for a drug multi-peak phenomenon. The method includes the following steps: selecting at least 6 dogs with three male dogsand three female dogs, carrying out dosing based on a certain dosage, collecting blood samples after dosing, for a blood sample time point, at least collecting two block sampling points before a first peak, at least collecting three blood sampling points near a highest value of each peak, and at least collecting three blood sampling points after a last peak; measuring the blood drug concentrationby using a liquid mass spectrometer; and calculating a fitting constant (DM) for five types of each dog and indicating a minimum value to be a pharmacokinetic standard model class of the dog. According to the invention, the standard model can be established in the dog, the pharmacokinetic parameters of the drug are calculated correctly, and thus a reasonable dosing plan is provided. The method also can be used for calculating and predicting the drug concentration of the drug in the dog, so that a defect of excessive dog dosing amount due to the small pharmacokinetic parameters of the drug formulti-peak phenomenon calculation by the existing pharmacokinetic software is overcome.

A positive-pressure tube sealing joint relates to the technical field of medical equipment and comprises a first shell, a containing cavity and a liquid storage cavity are arranged in the first shell, and a tube sealing liquid valve is arranged on a hole channel communicated between the containing cavity and the liquid storage cavity. According to the positive-pressure tube sealing connector, tube sealing liquid can be rapidly and conveniently injected into the extension tube, blood in the extension tube flows back, automatic positive-pressure tube sealing is achieved, and the working efficiency is improved.

The invention belongs to the technical field of medical equipment, and particularly relates to an artificial intelligence-based self-service system before outpatient blood sampling. A touch control screen is connected with a control management system in a machine body, and the control management system comprises a personal information input module and a test tube selection module; the personal information input module comprises a personal information unit and a symptom selection unit; the test tube selection module comprises a test tube selection unit and a feedback unit; and the test tube selection unit comprises a test tube sorting mechanism, a test tube labeling mechanism and a test tube marking mechanism. The equipment meets the intelligent operation of a medical institution outpatient service blood sampling window integrating number taking, blood sampling test tube self-service and receipt, and compared with a series of steps such as bar code and receipt printing, item checking, test tube selecting and bar code pasting of workers, the equipment improves the efficiency of the workers, reduces the error rate caused by manual labeling, saves the doctor-patient time of patients, relieves the fear of the patient, and the increases a space utilization rate of the blood drawing table board.

The invention relates to a blood sampling device, in particular to an intelligent blood sampling device for a clinical laboratory. The invention provides the intelligent blood sampling device for the clinical laboratory, which can automatically draw blood, automatically disinfect and automatically shake the blood. The intelligent blood sampling device for the clinical laboratory comprises a needle head, and the needle head is arranged in the middle of a needle tube in a threaded mode; the clamping mechanism is arranged on the needle tube; the disinfection mechanism is arranged on the needle tube; and the extraction mechanism is arranged on the disinfection mechanism. According to the invention, the needle tube and the liquid extraction tube are disinfected through the disinfectant, so that the needle tube and the liquid extraction tube are prevented from being polluted by bacteria, the bacteria are killed, and the bacteria killing effect of the disinfectant is achieved; suction force is generated through a telescopic rod of the first electric push rod, so that blood of a patient flows into the liquid extraction pipe through the needle, and the automatic blood extraction effect is achieved.
