Embodiment 1

[0048] The PRP centrifugal sleeve can reduce the preparation time of PRP and avoid the trouble and pollution risk of the second centrifugation operation, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, specifically set to the following structure:

[0049] Basically, the PRP centrifugal sleeve consists of an outer sleeve 1 and a helical coil 2 . The top of the outer sleeve 1 has an opening for loading the helical coil 2 and the blood collection tube, the bottom of the outer sleeve 1 is closed, and the outer sleeve 1 can be directly or indirectly connected with the rotating shaft of the centrifuge. The space is used to set the helical coil 2 and the blood collection tube. The helical coil 2 is arranged on the inner side of the outer sleeve 1, and the helical coil 2 is formed by helically winding a wire around the axis of the outer sleeve 1. The helical coil 2 is used to be wound around the periphery of the blood collection tube loaded into the outer sleeve 1, ...

Embodiment 2

[0054] This embodiment is further optimized on the basis of the above-mentioned embodiments, further to better realize the present invention, especially adopt the following configuration structure:

[0055] The PRP centrifugal sleeve also includes an inner sleeve 3. The bottom of the inner sleeve 3 is closed, and the top of the inner sleeve 3 has an opening. The inner space of the inner sleeve 3 is used for inserting blood collection tubes. After entering the inner sleeve 3, it can be fixed by the inner sleeve 3. The inner sleeve 3 is inserted into the inner side of the outer sleeve 1, and the outer sleeve 1 and the inner sleeve 3 can be fixedly connected as an integrally formed structural member, or can be detachably connected as a combined structural member composed of two independent parts. When the outer sleeve 1 and the inner sleeve 3 are detachably connected combined structural parts, it is convenient to replace or maintain the helical coil 2 inside. The inner sleeve 3 ...

Embodiment 3

[0058] This embodiment further provides a PRP centrifuge on the basis of the above embodiments, which can reduce the preparation time of PRP and avoid the trouble and pollution risk of the secondary centrifugation operation, and especially adopt the following configuration structure:

[0059] This PRP centrifuge includes a centrifuge main body 5 and the PRP centrifuge sleeve in Example 2.

[0060] A pulse current generator 7 is built in the centrifuge main body 5, and a sleeve frame 6 is fixedly connected to the rotating shaft of the centrifuge main body 5. The sleeve frame 6 is fixed to the rotating shaft of the centrifuge main body 5 through the shaft sleeve of the center, and the shaft sleeve of the sleeve frame 6 is provided with a connecting arm for connecting the outer sleeve 1, and the outer sleeve 1 is installed on the sleeve frame 6. Fixed at the connecting arm.

[0061] The pulse current generator 7 is installed inside the centrifuge main body 5 . Two conductive sl...

Abstract

The invention provides a PRP centrifugal sleeve, a PRP centrifuge and a PRP preparation method, relates to the technical field of PRP preparation, and solves the problems of long preparation time of PRP and infection risk in secondary centrifugation. The two connection ends of the helical coil are used to connect with the power supply; the helical coil is helically wound around the axis of the outer sleeve and wound around the periphery of the blood collection tube packed in the outer sleeve. The rotating shaft of the centrifuge main body of the PRP centrifuge is fixed with a sleeve frame, and the outer sleeve is installed on the sleeve frame; the pulse current generator is installed on the centrifuge main body, and the pulse current generator is electrically connected with the helical coil. In the PRP preparation method, a pulsed alternating current is passed to the helical coil during centrifugation, so that the magnetic field of the helical coil produces a direction change to act on the charged growth factor in the blood collection tube, which can reduce the preparation time of PRP and avoid the trouble and trouble of the second centrifugation operation. pollution risk.

Description

technical field [0001] The invention relates to the technical field of PRP preparation, specifically, a PRP centrifuge sleeve for preparing PRP, a PRP centrifuge provided with the PRP centrifuge sleeve and a PRP preparation method using the PRP centrifuge. Background technique [0002] PRP (Platelet-rich plasma) is a plasma component containing a large number of platelets obtained by centrifuging and extracting autologous blood, and the platelet content contained in it is significantly higher than that in normal human plasma. [0003] Centrifugation methods can be divided into two broad categories: single centrifugation and double centrifugation, with the latter being the most commonly used. Double centrifugation generally first undergoes relatively low-speed centrifugation (speed 100×g, centrifugation for 10 minutes) to separate plasma and platelets from red blood cells and white blood cells, and then undergoes relatively high-speed centrifugation (centrifugation force 400×...
