Description

Technical Field

[0001] The invention relates to the technical field of medical detection, and in particular to a urine sample centrifugal device. Background Art

[0002] Urine testing is one of the three major routine tests. It is generally used to detect diseases of the urinary system and observe the efficacy of treatment. It is also a common laboratory test method. Traditional urine testing requires manual testing. After manual sampling, the test strip is soaked in the urine sample, and then the urine test scans the test strip to see what is happening. Generally, the urine needs to be observed after sedimentation through scanning and microscopic analysis.

[0003] Existing urine testing and analysis include dried analysis and microscopic analysis. Microscopic analysis is to detect substances through a microscope, but the efficiency of natural sedimentation is very low, and a centrifugal device is often required to accelerate the sedimentation process.

[0004] However, for some people who need to test urine regularly, it is very inconvenient to always go to the hospital to borrow equipment. Therefore, a portable urine test device is needed to assist in urine testing at home. Summary of the invention

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a urine sample centrifuge device, which can ensure that the test sample can fit the sterile environment in the hospital as much as possible through a closed environment and sterilization and disinfection, and ensure that urine tests can be performed at home by yourself.

[0006] To achieve the above object, the present invention provides the following technical solutions: A urine sample centrifuge device comprises a centrifuge housing, a sample processor and a holding tank for injecting samples, wherein a disinfection injection port for disinfection is provided in the centrifuge housing, a connecting plate is provided in the centrifuge housing, sample fixing frames are fixedly connected at both ends of the connecting plate, a sample tube rack is provided on the sample fixing frame, a plurality of sample tubes are installed in the sample tube rack, and a rotating assembly for driving the connecting plate to rotate is provided in the centrifuge housing.

[0007] Furthermore, the rotating assembly includes a moving frame installed in the centrifuge housing, a rotating disk is installed on the moving frame, a rotating shaft is installed on the rotating disk, and a motor for driving the rotating shaft to rotate is provided in the rotating disk.

[0008] Furthermore, a chuck is fixedly connected to the free end of the rotating shaft, a slide groove is provided on the chuck, the connecting plate is slidably connected in the slide groove, and a rotating motor is provided in the chuck to drive the connecting plate to rotate.

[0009] Furthermore, a fixed frame is provided in the centrifuge shell, a fixed plate is installed on the fixed frame, a guide rail is provided on the fixed plate, a sliding groove is provided in the movable frame, a slider is installed in the sliding groove, and the slider is connected to the guide rail.

[0010] Furthermore, an injection cavity for the connecting plate to extend into is provided at one end of the sample processor connected to the centrifuge housing.

[0011] Furthermore, a first telescopic rod is provided at the bottom of the centrifugal chamber in the centrifuge housing, and a connecting groove is provided at the bottom of the movable frame, and the first telescopic rod abuts against the connecting groove when extended.

[0012] Furthermore, a closed shell is provided on the centrifuge housing, and a retractable telescopic plate is provided on the closed shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention can centrifuge urine in a closed environment. Centrifugation inside can avoid excessive contact of the sample with the air. After ensuring the sterility of the environment, the contact of the sample with the outside world can be further reduced. Urine can also be stored before direct analysis and centrifugation, and sterilization and disinfection are performed to ensure that the test sample can fit the sterile environment in the hospital as much as possible, ensuring that urine testing can be performed by oneself at home.
