Description

A centrifuge device for medical testing

Technical field

The utility model relates to the technical field of centrifugal devices, and in particular to a centrifugal device for medical testing.

Background technique

A centrifuge is a machine that uses centrifugal force to separate components of liquids and solid particles or a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions (such as separating cream from milk); it can also be used to exclude Liquids in wet solids, such as drying wet clothes in a washing machine; special ultra-fast tube separators can also separate gas mixtures of different densities; taking advantage of the different sedimentation speeds of solid particles of different densities or particle sizes in liquids, some sedimentation Centrifuges can also classify solid particles by density or size.

For example, the Chinese patent with announcement number CN213494320U discloses a centrifugal device for medical testing. By setting up the second motor, when the staff uses the device to centrifuge the medicine, the staff only needs to start the second motor through the control switch. With the cooperation of the first gear and the second gear, the second rotating shaft can be rotated. The placement tank is driven to rotate, thereby achieving the purpose of centrifugal operation of the medicine. However, during the centrifugal operation, the drug is too close to the rotation axis, and we know that the farther away from the rotation axis, the greater the centrifugal force, and conversely, the smaller the centrifugal force, which may result in poor separation of the sample during centrifugation operation. It is conducive to medical examination; in view of this, we propose a centrifuge device for medical examination.

Detailed ways

The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example

As shown in Figures 1-4, the utility model proposes a centrifugal device for medical testing, which includes a box 1. The top of the box 1 is hinged with a cover 2. The cover 2 is used to close the box 1 for convenience. Perform centrifugation. A handle 3 is installed on the top of the cover 2, and the handle 3 is arranged to facilitate opening the cover 2. A rotating cavity 4 is provided in the box 1, and the rotating cavity 4 is a centrifugal operating space. A mounting column 5 is provided in the rotating cavity 4, and the mounting column 5 is the rotation axis during centrifugation. There are multiple sets of connecting rods 6 fixedly connected to the top of the mounting column 5. A U-shaped mounting rod 7 is installed on one end of the connecting rod 6 away from the mounting column 5. The connecting rod 6 is used to drive the U-shaped mounting rod 7 to rotate with the mounting column 5 as the rotation axis. . The U-shaped mounting rod 7 is provided with a placement sleeve 8. When the U-shaped mounting rod 7 rotates, the placement sleeve 8 is driven to rotate. The test tube 9 is placed in the placement cover 8. The placement cover 8 is used to place the test tube 9. The test tube 9 is used to hold the test sample. After centrifugation, the sample is layered to facilitate inspection. A sealing cover 17 is installed on the top of the test tube 9, and the sealing cover 17 is used to seal the upper opening of the test tube 9 to prevent sample leakage during the centrifugation process. There is also a motor cavity 10 in the box 1. The motor cavity 10 is located at the lower center of the rotating cavity 4. A servo motor 11 is installed in the motor cavity 10. The output end of the servo motor 11 is fixedly connected to the mounting column 5. The servo motor 11 is To drive the motor cavity 10 to rotate. Multiple sets of fixed rods 12 arranged at an angle are installed at the bottom of the rotating cavity 4. The top ends of the multiple sets of fixed rods 12 are fixedly connected with positioning sleeves 13. The fixed rods 12 are used to fix the position of the positioning sleeves 13. The positioning sleeve 13 is set on the outer ring of the installation column 5. The installation column 5 is rotationally connected to the positioning sleeve 13. The rotation connection is used so that the positioning sleeve 13 does not hinder the rotation of the installation column 5. The outer ring of the installation column 5 is also fixedly installed with a limit ring 14. The limit ring 14 is located at the position of the positioning sleeve 13, and the limit ring 14 is rotationally connected with the positioning sleeve 13.
