Problems solved by technology

However, the existing platelet-rich plasma (PRP) preparation mainly has the following defects: (1) the concentration of platelet-rich plasma (PRP) is low, and the separated platelet-rich plasma (PRP) is light red, and red blood cells are mixed in it; (2) Residual separation agent, separation reagent used in platelet extraction, there is residue; (3) The extraction process and preparation method are complicated, in order to obtain a higher concentration of platelet-rich plasma (PRP), it needs to be separated and extracted many times, and the structure of the centrifuge tube is complicated, which is easy to cause Platelet Rich Plasma (PRP) Contamination

Embodiment 1

[0028] Such as figure 1 As shown, the centrifuge tube 1 is composed of a thin-walled hose with a sealed bottom. The centrifuge tube 1 has a slender tubular structure. The centrifuge tube 1 has a fixer 3 suitable for a centrifuge. Compatible with the outer surface of the structure, the fixer 3 includes a male head fixed with a socket convex key 4 and a female head fixed with an interface groove 5 , and the socket convex key 4 matches the interface groove 5 . There is a tube cover 2 on the top of the centrifuge tube 1, the inner diameter of the tube cover 2 is compatible with the outer diameter of the centrifuge tube 1, and the outer wall of the tube cover 2 is provided with anti-slip lines along the axial direction. Centrifuge tube 1 tube body has measuring scale.

Embodiment 2

[0030] Such as figure 2 As shown, the centrifuge tube 1 is made of a thin-walled flexible tube with a sealed bottom. The centrifuge tube 1 is in a thin dumbbell-shaped structure. The dumbbell-shaped bottom of the centrifuge tube 1 is an arc bottom. The inner surface of the fixer 3 is adapted to the outer surface of the elongated structure of the centrifuge tube 1. The fixer 3 includes a male head fixed with the socket convex key 4 and a female head fixed with the interface groove 5, the socket convex key 4 and the interface groove 5 match. There is a tube cover 2 on the top of the centrifuge tube 1, the inner diameter of the tube cover 2 is compatible with the outer diameter of the centrifuge tube 1, and the outer wall of the tube cover 2 is provided with anti-slip lines along the axial direction. Centrifuge tube 1 tube body has measuring scale.

Embodiment 3

[0032] Such as image 3 As shown, the dumbbell-shaped bottom of centrifuge tube 1 is a conical bottom.

Abstract

The invention relates to a medical apparatus design, in particular to a centrifuge tube and a method for preparing platelet-rich plasma. The invention discloses a method for achieving aseptic preparation of the platelet-rich plasma (PRP) by designing a centrifuge tube structure and adopting heat-sealing machine separation. The centrifuge tube provided by the invention is formed by a thin-wall hose with a sealed bottom, at least part of the centrifuge tube has a slender structure, the centrifuge tube is has a fixer suitable for a centrifuge, and the inner surface of the fixer matches the outer surface of the slender structure of the centrifuge tube. The top of the centrifuge tube is provided with a tube cover, the inner diameter of the tube cover matches the outer diameter of the centrifuge tube, the outer wall of the tube cover is provided with antiskid stripes along the axial direction, and the tube body of the centrifuge tube is provided with measurement scales. The invention also provides the method for preparing the platelet-rich plasma based on the centrifuge tube. The platelet-rich plasma provided by the invention has the characteristics of being simple in preparation method, pollution-free in a preparation process, high in purity of the platelet-rich plasma (PRP), easy in storage, convenient in use, and the like.

Description

technical field [0001] The invention relates to a design of medical equipment, in particular to a centrifuge tube and a method for preparing platelet-rich plasma. Background technique [0002] Platelet-rich plasma (PRP) contains a large number of growth factors, such as platelet-derived growth factor (PDGF), transforming growth factor-β (TGF-β), insulin-like growth factor (IGF), epidermal growth factor (EGF), vascular endothelial growth These growth factors are mainly secreted by platelet activation, which can promote cell and matrix regeneration, promote tissue repair, rapidly stop bleeding, relieve pain, accelerate wound healing, and greatly reduce the formation of postoperative scars. Widely used in various surgical operations, heart surgery and plastic surgery, also widely used in medical cosmetology. However, the existing platelet-rich plasma (PRP) preparation mainly has the following defects: (1) the concentration of platelet-rich plasma (PRP) is low, and the separate...
