[0002] At present, clinically, when taking blood from a patient's vein, after the injection needle is pulled out, most of them use a sterile cotton swab to press the needle site to stop bleeding. The sterile cotton swab is small in size and the pressing range is limited, and the needle hole in the skin cannot be pressed at the same time. Needle entry point, causing blood to seep from the blood vessel at the point of needle entry, resulting in a large area of subcutaneous congestion after the patient is pressed, causing great pain to the patient

Disclosed is a clinical laboratory hemostatic device. The clinical laboratory hemostatic device comprises a pressure plate, a pressurizing airbag, a first fixing band and a second fixing band, whereinthe middle of one side of the pressure plate is provided with a groove inside which the pressurizing airbag is arranged, the bottom of the pressurizing airbag is provided with a hemostatic pad, and the bottom of the hemostatic pad is provided with a sterile film; the bottom of the edge of the groove is provided with an elastic ring; the pressure plate is provided with an air nozzle through hole,the top of the pressurizing airbag is communicated with an air nozzle, and one end of the air nozzle penetrates through the air nozzle through hole and out of the pressure plate; one end of the pressure plate is provided with the first fixing band, the other end of the pressure plate is provided with the second fixing band, and between the first fixing band and the pressure plate as well as between the second first fixing band and the pressure plate are provided with elastic fabric. The clinical laboratory hemostatic device is large in pressing area and capable of avoiding oozing of blood froma needle inserting point of a vessel, thereby achieving pressurized hemostasis and meanwhile ensuring breathability of the bleeding part of a patient to facilitate wound healing, and further avoidinglarge-area pressed subcutaneous ecchymosis of the patient.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a hemostatic device for laboratory. Background technique [0002] At present, clinically, when taking blood from a patient's vein, after the injection needle is pulled out, most of them use a sterile cotton swab to press the needle site to stop bleeding. The sterile cotton swab is small in size and the pressing range is limited, and the needle hole in the skin cannot be pressed at the same time. The needle entry point causes blood to ooze from the blood vessel at the needle entry point, resulting in a large area of subcutaneous congestion after the patient is pressed, causing great pain to the patient. Contents of the invention [0003] The object of the present invention is to provide a hemostatic device for clinical laboratory, which has a wide range of pressure, prevents blood from seeping out from the needle entry point of the blood vessel, realizes pressure hemos...
