Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a pretreatment centrifuge. Background Technique

[0002] In medical examinations, centrifuges are often used as instruments for separating serum, plasma, precipitating proteins, or performing urine sediment examinations. By using a centrifuge, suspended particles in a mixed solution can be quickly precipitated, thereby separating components of various substances with different specific gravities. Medical centrifuges are widely used in biological, clinical, laboratory medicine, biochemistry and other application scenarios. Before centrifugation, existing test tubes may pre-store detection reagents. When loading or taking out the detection reagents, the reagents may stick to the inner wall of the test tube. Also, the blood samples to be tested need to be transported to the testing point after extraction, and blood may remain on the inner wall of the test tube during transportation, which may affect subsequent test results. Existing medical centrifuges usually need to place a fixed number of test tubes to perform centrifugation work, making it difficult to meet the needs of highly efficient and flexible working scenarios such as laboratories and emergency rooms. Content of the Utility Model

[0003] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a pretreatment centrifuge.

Inside the centrifuge housing, there is a platform which is fixed in the centrifuge housing through shock-absorbing brackets. On the platform, there is a motor assembly. A centrifugal rotating plate is rotatably connected to the motor assembly. Below one end of the centrifugal rotating plate, there is a self-balancing device, and the other end is fixedly connected to a test tube basket. Inside the test tube basket, there is a detachable test tube rack. During use, the test tube rack with test tubes is placed into the test tube basket, and when performing pretreatment work, the overall center of gravity position is adjusted through the self-balancing device.

[0005] Preferably, the self-balancing device includes a bracket suspended at the bottom of one end of the centrifugal rotating plate and a linear driving device arranged inside the bracket.

The lead screw-nut sleeve structure includes a lead screw and a nut sleeve. A counterweight is fixedly connected to the nut sleeve, and both guide rails pass through the counterweight. During use, the motor drives the lead screw-nut sleeve structure to drive the counterweight to translate along the guide rail to adjust the center of gravity position of the self-balancing device.

[0006] Preferably, a weighing sensor is arranged inside the shock-absorbing bracket to detect the weight of the items in the test tube basket.

[0007] Preferably, a vibration sensor is provided on the platform. The operating state of the centrifuge is detected by the vibration sensor, and when the vibration exceeds the set parameters, the centrifuge stops running.

[0008] Preferably, a top cover is fixedly connected to the top surface of the centrifuge housing. Two slide rails are fixedly connected to the top cover. An activity plate is arranged between the slide rails. When in use, the test tube is placed or taken out by opening the activity plate.
