A blood centrifuge

Abstract

This utility model discloses a blood centrifuge, comprising: a centrifuge body, a receiving groove on one side of the top of the centrifuge body, a centrifuge turntable movably mounted in the receiving groove, a receiving groove on the surface of the centrifuge turntable, fastening components on both sides of the inner wall of the receiving groove, arc-shaped clamping plates in the empty slots on both sides of the inner wall of the receiving groove, a support frame on one side of the arc-shaped clamping plates, and an electric telescopic rod on one side of the support frame. This utility model, by setting up fastening components and positioning blocks, allows centrifuge tubes to be quickly placed into the positioning blocks and fastening components through the receiving groove. The positioning groove has a gradient texture and an anti-slip rubber pad on its inner surface to position the centrifuge tubes and prevent slippage. The electric telescopic rod drives a pushing block, which in turn drives trapezoidal sliders on both sides of the pushing block to slide within a trapezoidal groove in a movable block, thereby moving the movable block and causing the arc-shaped clamping plates to clamp and fix the centrifuge tubes, achieving the purpose of quickly fixing test tubes of different sizes.

Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a blood centrifuge. Background Technology

[0002] Plasma, as a component of blood, is collected primarily through the separation of blood. Common methods for plasma collection include centrifugation and membrane filtration. Because blood contains clotting factors, regardless of the collection method, anticoagulation treatment is necessary after the blood is drawn from the body. Currently, secondary plasma processing technology is widely used in areas such as removing pathogenic substances and treating acute and critical illnesses. Its basic principle involves separating the patient's blood into plasma and blood cells using centrifugal force generated by high-speed rotation in an in vitro centrifuge. The blood cell components are then returned to the patient. The separated plasma is then processed through a filter, and finally, the processed plasma is returned to the patient.

[0003] A search revealed Chinese Patent Publication No. CN202421585485.0; the invention includes a chassis with a placement slot at the top. A rotating shaft is rotatably connected to the bottom of the placement slot, and a rotor is inserted into the outer side of the rotating shaft. Limiting slots are formed on both sides of the top of the rotating shaft, and a fixing ring is slidably connected to the outer side of the top of the rotating shaft. Mounting slots are formed on both sides of the inner sidewall of the fixing ring, and springs are fixedly connected to the inner sidewalls of both mounting slots. Limiting blocks are fixedly connected to the other ends of both springs, and the other ends of both limiting blocks are slidably connected inside the limiting slots. Positioning slots are formed on both sides of the inner sidewall of the rotor, and positioning blocks are slidably connected inside both positioning slots. In this invention, pulling the fixing ring upwards causes the limiting slots to compress the limiting blocks and retract them into the mounting slots, thereby removing the fixing ring from the top of the rotating shaft and pulling the rotor upwards to remove the rotor from the outside of the rotating shaft. However, in this application, blood test tubes are placed into angled receiving slots arranged in a circular array. When multiple tubes are placed, they need to be manually aligned in different directions, which can easily cause them to obstruct each other. Furthermore, the size of the receiving slots is fixed.
