Abstract

The invention discloses an anticoagulant-free PRP (platelet-rich plasma) biological membrane preparation device and method. On one hand, the anticoagulant-free PRP biological membrane preparation device comprises a tray body, a cavity is formed in the tray body, and a plurality of burr protrusions are evenly arranged on the bottom face of the cavity; a pipe joint penetrating through the side wall of the cavity is arranged on the tray body, a valve is arranged on the pipe joint, and the pipe joint is communicated with a blood collection needle in an inserted mode; the tray body is sealed and covered with a medical protective film; an insertion opening communicated to the inner wall of the cavity is formed in a notch of the cavity; and a negative suction mechanism is detachably inserted into the insertion opening. On the other hand, the preparation method of the anticoagulant-free PRP biological membrane, provided by the invention, comprises the processes of assembling the preparation device of the anticoagulant-free PRP biological membrane, collecting blood, standing for blood coagulation and the like, and is simple to operate. By means of the anticoagulant-free PRP biological membrane preparation device and method, the PRP biological membrane can be prepared with high efficiency and low cost.

Description

technical field [0001] The present application relates to the field of PRP biofilm preparation devices, in particular to an anticoagulant-free PRP biofilm preparation device and method. Background technique [0002] At present, in the treatment of protracted wounds, platelet-rich (PRP) biofilms are often used clinically for treatment. [0003] At present, there are two commonly used methods for preparing platelet-rich biofilms: one is to collect blood from patients, add anticoagulants such as sodium citrate to avoid blood coagulation, and separate the collected blood through a centrifugal separator to obtain platelet layers. , and then add calcium chloride and other recoagulants, spread the liquid into a film and wait for coagulation to form a platelet-rich biofilm; the other is to collect blood from the patient, which is naturally coagulated under the action of its own coagulation factors, and collected by sterile tweezers Congealed clot, by mechanically compressing the cl...
