Venous blood sampling hemostatic patch for people with low blood platelets

Abstract

The invention provides a venous blood sampling hemostatic patch for people with low blood platelets. The venous blood sampling hemostatic patch includes a main body pad; hemostatic cotton is fixedly connected to the bottom of the main body pad; the interior of an air cavity is filled with hemostatic drug powder; an end cap is arranged in a nozzle; a sliding plate is inserted into the main body padand located on the outer side of the nozzle in a sliding mode, a sharp head and a through hole are formed in the sliding plate, a baffle penetrating through the sliding plate is movably inserted intoa right connecting base, a rubber band is arranged at the top of a left connecting base, and bandages are fixedly connected to the sides, opposite to each other, of the two connecting bases. When venous blood sampling hemostasis is carried out on the patient with low blood platelets, the main body pad is placed on a puncture point wound, a pressing pad is pressed, then a handle is hooked and lifted upwards, the sliding plate is pulled by a stretching device to move leftwards, the sharp head punctures the end cap, air pressure in the air cavity blows the hemostatic drug powder outwards, hemostasis is carried out on the wound, the blood coagulation time is shortened, and thus the workload of the patient and medical staff is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a venous blood collection hemostatic patch for people with low platelets. Background technique [0002] Platelets are one of the formed components of blood. They are small pieces of cytoplasm that come off from the mature megakaryocytes in the bone marrow. They play an important role in the process of bleeding and coagulation. When people's traumatic blood vessels rupture, they will cause bleeding. Platelets gather in the ruptured blood vessel to form a blood clot, which blocks the opening of the blood vessel and stops bleeding. [0003] Because platelets play an important role in the process of hemostasis, low platelets in the blood of the human body will cause bleeding problems that are difficult to stop. In normal treatment and physical examination, there are often blood collection items, in the veins of the arms Needle pricking to draw blood, but for patients with ...
