A multi-purpose platelet plasma preparation device

Abstract

The invention discloses a multi-purpose platelet plasma preparation device, which relates to the technical field of platelet plasma preparation and includes a multi-purpose separation and injection component, a blood collection and storage component, a two-way limit mechanism, a pure serum filtration unit, a mixed platelet serum collection and storage component, and a mixed platelet serum The filter unit and the two-way limit mechanism can bidirectionally fix the piston at the inner end of the mixed platelet serum collection and storage component and the separation injection component. It will not shake when pushed and pulled, and the piston at the inner end of the collection and storage component is not directly connected with the separation injection component, so there is no possibility of falling off; the red blood cells that enter the mixed platelet serum collection and storage component are filtered and removed, and will enter the multipurpose separation The serum containing a small amount of free platelets mixed in the injection components is removed by filtration, so as to effectively ensure the quality of the extracted platelet-rich plasma.

Description

technical field [0001] The invention relates to the technical field of platelet plasma preparation, in particular to a multipurpose platelet plasma preparation device. Background technique [0002] Platelet-rich plasma (Platelet-rich plasma, referred to as PRP) is a platelet concentrate obtained after centrifugation of autologous whole blood. PRP contains a large number of growth factors and proteins. It can promote cell and tissue regeneration from different aspects, thereby accelerating the repair of damaged tissue, and is widely used in clinics, such as the repair of bone and joints, the repair of large-area burn skin, and the fields of medical beauty and plastic surgery. CN201920333426.7 Disclosure A platelet-rich plasma separation and extraction kit is developed, which can prevent the plasma from contacting the external environment to be polluted, and does not require an automatic platelet separator. Part of it is not fixed. During blood collection and separation and e...

AI Technical Summary

Problems solved by technology

CN201920333426.7 discloses a platelet-rich plasma separation and extraction kit, which can prevent the plasma from being polluted by contact with the external environment, without the need for a fully automatic platelet separator, but the bottom of the syringe is directly threaded with the top of the tube for blood collection, so that The upper part of the syringe is not fixed. During blood collection and separation, the syringe needs to be pushed and pulled up and down. The upper part of the syringe is easy to shake, resulting in deformation of the threaded connection between the bottom of the syringe and the tube, and the possibility of falling off. and during blood collection, usually only a single tube of blood can be collected, and the blood collection efficiency is not good. When there are many needs for blood collection, the suit needs to be pulled out, and another suit is inserted for blood collection, which greatly reduces the comfort of the patient. After centrifugation, the blood will be divided into three layers, the upper layer is serum, the middle layer is light yellow thin layer (platelets), and the lower layer is red blood cells. During extraction, some red blood cells and thin layers will flow along the inner tube Into the syringe, the quality of the extracted platelet-rich plasma is poor, and the concentration of platelets cannot reach the 1000*10 required in the "National Expert Consensus on the Application of Concentrated Platelet Products in Wound Repair (2020 Edition)" 9 The standard of individual / ml influences the effect of treatment, therefore, urgently need those skilled in the art to design a kind of new platelet-rich plasma preparation device
