Description

Platelet-rich plasma preparation device for once centrifugal blood Technical Field The utility model relates to the technical field of blood separation devices, in particular to a device for preparing platelet-rich plasma by once centrifuging blood. Background Blood is mainly composed of plasma, platelets, and blood cells, wherein platelets are rich in components required for regeneration and repair of human tissue. In the course of blood centrifugation, plasma, platelets and blood cells can be separated according to the weight difference of each component, and platelet rich plasma (PRP: PLATELET RICH PLASMA) containing abundant platelets and platelet poor plasma (PPP: platelet Poor Plasma) containing no platelets are formed. Because the platelet contains various growth factors, the platelet plays a key role in wound healing, skin regeneration and the like. Research reports show that the high-concentration PRP is rich in platelets, and various growth factors in the high-concentration PRP can promote the proliferation of surrounding cells, and have the remarkable effect of promoting the synthesis of components such as collagen. Based on this, PRP has been widely used in various medical fields such as pain treatment of lumbago, alopecia treatment, skin regeneration treatment, and burn treatment. Currently, most existing blood separation devices acquire PRP by means of secondary centrifugation. According to the method, the erythrocyte layer is required to be centrifugally separated for the first time, and then the PRP is required to be centrifugally separated for the second time, so that the whole operation flow is complicated, the time consumption is long, a patient needs to wait for a long time, and the clinical treatment efficiency is greatly influenced. Therefore, developing a high-efficiency and convenient one-time centrifugal blood platelet-rich plasma preparation device has important clinical application value and practical significance. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide the preparation device capable of obtaining high-concentration platelet-rich plasma by single centrifugation. The technical scheme includes that the one-time centrifugal blood platelet-rich plasma preparation device comprises a device main body, an upper cover and a red blood cell storage cover, wherein the upper cover covers the top of the device main body, the red blood cell storage cover is connected to the bottom of the device main body, the device main body is in a shape of tightening towards the center, a blood channel is formed by a tightening part and is provided with a rotary switch, a platelet plasma storage chamber is arranged above the rotary switch, a red blood cell storage chamber is arranged below the rotary switch, and the connection depth of the red blood cell storage cover and the device main body can be adjusted so as to adjust the height of a layering section, and a suction hole is formed in the platelet plasma storage chamber. Further, the upper cover is connected with the device main body through threads. Further, the red blood cell storage cover is connected with the device main body through threads, and the capacity of the red blood cell storage chamber is changed through rotation of the threads, so that the purpose of fine adjustment of the height of the layered section is achieved.

Furthermore, sealing rings are arranged at the joints of the device main body, the upper cover and the red blood cell storage cover. Further, the rotary switch is provided with a radial through hole, and through changing the relative position of the through hole and the blood channel, the platelet plasma storage chamber and the erythrocyte storage chamber are communicated or blocked. The preparation device of the platelet-rich plasma by one-time centrifugation has the beneficial effects that: 1. The method is efficient and time-saving, breaks through the technical limitation of obtaining Platelet Rich Plasma (PRP) by traditional secondary centrifugation, and greatly reduces the whole operation flow by adopting a primary centrifugation mode.
