Description

Platelet gel shaper for wound surface of patient

Technical Field

The invention relates to the technical field of medical instruments, in particular to a platelet gel shaper for a wound surface of a patient.

Background

Platelet-rich plasma (PRP) is a platelet-rich concentrate extracted from autologous whole blood, prepared by manual collection of whole blood or isolated from a blood component separator, and was used early as a barrier membrane and biogel for clinical hemostasis.

The PRP concept was first proposed by Hood in 1993 and found to contain an enriched number of platelets in PRP, 3-7 times higher than in whole blood. With the intensive research of PRP, it was found that PRP contains a large amount of important growth factors such as VEGF, PDGF, IGF, EGF, etc., which have very important roles in regulating cell regeneration, differentiation and extracellular matrix synthesis. With the continuous exploration and new discovery of PRP in the aspect of clinical application, the mileage of PRP for repairing intractable exposed wound surfaces, organs and bone tissues in body cavities is opened, and the curative effect of PRP is approved by the medical industry and patients.

When the platelet-rich plasma is directly applied to the wound surface of a patient, as the platelet-rich plasma is in a liquid state and the absorption capacity of the wound surface is limited, a part of the product flows out of the wound surface or is absorbed by wound auxiliary materials, and the expected effect cannot be achieved. The problem can be solved by adding a certain proportion of platelet activating agent, and applying the platelet-rich plasma after being agglutinated into platelet gel to the wound surface of a patient.

However, with the popularization of the application and the summary of the application process, the application of the PRP gel is found to have many places to be improved. Such as: the wound surface of the patient has different shapes, sizes and depths, and the PRP gel is directly covered on the wound surface with smaller area. For the wound surface with a large area, the gel directly covering a large area can cause the waste of precious PRP resources, so that the medical staff strives to agglutinate the PRP into a gel shape matched with the wound surface of the patient. However, neither expensive PRP preparation kits nor manually separated and machine collected PRP products can properly aggregate PRP into a gel shape that fits over the wound surface of a patient before the PRP is applied to the wound surface of the patient.
