Definitions
- the present invention relates to a kit for extracting the layer-separated buffy coat to the outside by centrifugation of blood, and more particularly, an injection for extracting the buffy coat, which is centrifuged by a centrifuge and separated into an intermediate layer, from the side. It relates to a bio kit for extracting body fluid containing stem cells that can be precisely and easily extracted and separated by a needle.
- blood transports oxygen received from the lungs to tissue cells, transports carbon dioxide from the tissue to the lungs and releases them, transports nutrients absorbed from the digestive tract to organs or tissue cells, and is an unnecessary substance for the body as a decomposition product of tissues transports it to the kidneys and excretes it from the body.
- Such blood consists of red blood cells, white blood cells, and platelets.
- platelets are mainly present in plasma, and plasma is divided into PRP (Platelet rich plasma) and PPP (Platelet poor plasma).
- PRP is used for therapeutic purposes because it plays a role in helping the generation of cells through stimulation of stem cells by implanting in pain areas, especially knee seat, ligaments, and muscles.
- PRP procedure Plate Rich Plasma, also called platelet-rich plasma technique, hereinafter referred to as “PRP procedure”. It refers to a procedure that heals wounds by injecting into the tissue to regenerate cells.
- Blood platelets are known to be rich in growth factors, and these platelets are known to proliferate cells in the human body, produce collagen, regenerate new blood vessels, and heal wounds.
- human blood contains about 100,000 to 200,000 platelets per microliter, and in order for the PRP procedure to be effective, platelets must be concentrated enough to contain more than 1 million platelets per microliter.
- a method of separating the collected blood into layers using a centrifuge is used.
- the red red blood cell layer is placed on the lowermost layer in the order of heaviness according to specific gravity. is formed, and a deep yellow buffy coat layer composed of white blood cells and platelets is formed on the red blood cell layer, and the uppermost layer on the buffy coat layer is a pale yellow plasma layer composed of plasma, which is separated by components.
- the volume ratio of each layer of blood thus separated is, on average, 45% of the red blood cell layer, 1% of the buffy coat layer, and 54% of the plasma layer.
- the PRP procedure extracts and uses the platelet-rich buffy coat layer from the blood separated as described above, and the ratio is only 1%.

It can be assembled to be movable up and down by having a female screw part for adjustment 34 on the upper outer surface so as to be screwed with the male screw part 24 for adjustment formed in (23).
- the control housing 30 when the control housing 30 rotates in a forward or reverse direction with respect to the body housing 20 in a screw method, the control housing 30 is the length of the main housing compared to the amount of rotation.
- the buffy coat separated as an intermediate layer because it can reduce or expand the volume of the centrifugal separation space formed by the upper cap 10, the body housing 20, and the control housing 30 while moving relative to each other in the vertical direction.
- the layer (S2) can be adjusted to correspond to the side cap 40 provided in the neck portion 21 having a constant inner diameter to be positioned properly.
- the side cap 40 corresponds to the sealing member 44 press-fitted to seal the blow-out hole 45a formed through the outer surface of the neck of the main housing. It is a cap member fixed to the neck portion 21 by forming a needle hole 42 of a certain size through the center of the body so that the end of the injection needle (N2) for extraction can enter and exit the region.
- the side cap 40 extends outward by a predetermined length from the outer surface of the neck portion 21 penetrating the outlet hole, and the sealing member 44 is press-fitted inside the hollow tube ( 45), the upper end and the inner surface are in contact and can be fixedly coupled by an ultrasonic welding method.
- the sealing member 44 is elastically press-fitted while the injection needle for extraction that enters through the needle hole 42 of the side cap penetrates into the inside of the neck portion 21, a rubber material to prevent external outflow of blood. It is preferable to consist of
- the blood separated into the red blood cell layer (S1), the buffy coat layer (S2) and the plasma layer (S3) injected into the inner space of the main housing 20 after centrifugation in the centrifuge is separated into the control housing.
- the buffy coat layer S2 which is the intermediate layer, corresponds to the side cap 40 of the neck portion 21 one-to-one with each other.
- the sealing member 44 made of a rubber material even if the injection needle for extraction is pulled out and separated from the sealing member 44
- the red blood cell layer (S1) or plasma layer remaining in the main body housing 20 after the separation of the buffy coat layer (S2) is because the area through which the extraction needle is penetrated is restored to its original state and resealed by its own elastic restoring force. (S3) can be prevented from leaking to the outside.
- the guide groove corresponding to the guide groove 32 formed in the longitudinal direction on the lower outer surface of the adjustment housing 30 (52) may be formed on the inner surface in the longitudinal direction to include a bucket housing (50) coupled to the control housing (30).
- the bucket housing 50 is coupled to the control housing so that, when accommodating the inside of the main housing, the opened upper inner edge of the bucket housing may be in contact with the outer surface of the upper housing of the main housing.
- the bucket housing 50 may have an annular ring-shaped locking jaw 54 protruding to be hooked and connected to the locking groove of the rotating body rotating at high speed by the rotational driving force of the motor member in the centrifugal separator.
- the kit 100 in which the blood, which is the object of centrifugation, is injected into the main housing is correspondingly inserted into the bucket housing, and then, in the centrifugation process, the rotating body of the centrifuge rotates at high speed to perform centrifugation of the blood. It is rotated at high speed with internally accommodated.
- the adjustment housing 30 disposed inside the bucket housing is moved relative to the longitudinal direction compared to the rotation amount by the upper cap 10, the body housing 20 and the adjustment housing 30. Since the volume of the formed centrifugal separation space can be reduced or expanded, the buffy coat layer (S2) separated into an intermediate layer is adjusted to correspond to the side cap 40 provided in the neck portion 21 with a constant inner diameter to position it in place. can do it
- neck portion 22 upper hollow tube
