Embodiment 1

[0040] Embodiment one is basically as attached Figure 1 to Figure 9 Shown:

[0041] combine Figure 1 to Figure 4, a centrifuge, including a housing 1, a cover 2, a centrifugal mechanism 3 located in the housing 1, a holding mechanism, a cover opening mechanism and a negative pressure mechanism 91, the cover 2 forms a closed after the housing 1 is closed Space, the cover body 2 is rotatably connected to the casing 1, the cover body 2 covers the casing 1, the centrifugal mechanism 3 includes a first driver 31, a placement frame 32 and a turntable 33, and the first driver 31 is fixedly connected to the bottom of the casing 1 , the first driver 31 adopts a servo motor, the bottom of the turntable 33 is integrally formed with a vertical shaft 331, the shaft 331 is fixedly connected to the first driver 31, the first driver 31 drives the turntable 33 to rotate, and the placement frame 32 is connected to the turntable 33 in rotation, The placement racks 32 are evenly distributed i...

Embodiment 2

[0058] Embodiment two is basically as attached Figure 10 As shown, embodiment two has carried out following improvement on the basis of embodiment one: between negative pressure machine 91 and negative pressure pipe 92, also be fixedly connected with disinfection tube 30, photocatalyst filter screen 40 and ultraviolet disinfection are installed in the disinfection tube 30 The lamp 50 and the photocatalyst filter screen 40 are V-shaped.

[0059] The specific implementation process is as follows:

[0060] After the negative pressure machine 91 sucks the aerosol out of the housing 1 through the negative pressure tube 92, the aerosol first enters the disinfection tube 30, and the photocatalyst filter screen 40 and the ultraviolet disinfection lamp in the disinfection tube 30 realize air purification. The disinfection and sterilization of the sol ensures the cleanliness of the gas discharged through the negative pressure machine 91.

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a centrifugal machine. The centrifugal machine comprises a placing frame and a rotary disc. Test tube holes used for placing test tubes are formed in the placing frame. The placing frame is connected to the rotary disc. Clamping sets are arranged in the placing frame, and each clamping set comprises clamping blocks symmetrically arranged along the test tube holes. The clamping blocks are slidably connected to the placing frame. The centrifugal machine further comprises a cover opening mechanism anda negative pressure mechanism. The cover opening mechanism comprises lifters and cover opening discs. The lifters drive the cover opening discs to ascend and descend. Guide rods are fixedly connectedto the cover opening discs. Cover openers are further connected to the cover opening discs. The guide rods can push the clamping blocks to move so as to clamp the test tubes, and the cover openers areused for opening test tube covers. The negative pressure mechanism generates negative pressure after the test tubes are uncovered so as to pump away the aerosol. According to the scheme of the centrifugal machine, the problems that in the prior art, after a specimen in a test tube is uncovered, the aerosol brings harm to medical staff, and after the specimen in the test tube is centrifuged, the specimen is moved and then uncovered, the operation is troublesome are solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a centrifuge. Background technique [0002] At present, almost all specimens in medical clinical testing are separated by centrifugation, and particles with low density are even centrifuged in a high-speed centrifuge. The centrifugation time is about 15 minutes to 30 minutes. Under the centrifugal rotation, a large number of bioactive particles contained in the specimen Aerosols such as viruses or viruses are separated from the specimens into a suspended state. When the specimens are opened (the specimens are usually packed in test tubes and centrifuged), the suspended bioactive particles or viruses will quickly float into the air, which is harmful to the staff and The environment causes great pollution, especially very small toxic or biologically active particles (below pm2.5) directly enter the respiratory tract, causing respiratory tract infection, and even enterin...
