Description

Technical Field

[0001] The utility model relates to the field of sample slicing, in particular to a sample slicing device. Background Art

[0002] The laboratory is a bridge between clinical medicine and basic medicine, including clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, blood transfusion and other sub-disciplines. Every day, it is responsible for testing various human and animal specimens from wards, outpatient and emergency patients, various physical examinations and scientific research. When testing, the samples obtained need to be sliced. The current slicing method is manual slicing or mechanical slicing.

[0003] According to the published patent 202020043630.8, a sample slicing device for a medical laboratory includes a telescopic plate and a cutting box. A spring is welded to the bottom inner wall of the telescopic plate, a scraper is welded to one end of the spring, a telescopic column is fixed to the top outer wall of the telescopic plate by screws, a cross plate is welded to the top outer wall of the telescopic column, a blade is welded to the center of the bottom outer wall of the cross plate, and the blade is located directly above the scraper. The present invention provides a sample slicing device for a medical laboratory, with a telescopic plate, a telescopic column, a blade, a scraper and a spring. After each slicing, the sample often sticks to the blade and is lifted up due to its particularity. Therefore, after the slicing is completed, the blade is driven to reset under the action of the telescopic column, and the scraper blocks the sample stuck to the blade under the action of the spring, so that the sample can fall completely on the placement table, thereby improving the convenience of the device, facilitating operation, and reducing the burden on medical staff. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: although the telescopic plate, the telescopic column, the blade, the scraper and the spring are provided, after each slicing, the sample often sticks to the blade and is lifted up due to its particularity. Therefore, after the slicing is completed, the blade is driven to reset under the action of the telescopic column, and the spring Under the action, the scraper will block the sample adhering to the blade, so that the sample can fall completely on the placement table, which improves the convenience of the device, is easy to operate, and reduces the burden on medical staff. It solves the problem that the blade of many sample slicing devices easily sticks to the sample during the slicing process, causing the trouble of sample scattering and confusion and the subsequent cleaning of the adhesion on the blade, which seriously affects the work efficiency of the staff and increases the workload of medical staff. During use, in the traditional sample slicing device, there is a certain distance between the placement plate and the scraper. When the blade moves up, although the scraper scrapes off the sample on the surface of the blade, the blade will move up as the sticky sample moves up. Even if the scraper can scrape off the sample, since the sample is at a certain height from the placement plate after moving up, the sample will fall to the top of the placement plate, causing damage to the sample surface. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Example 1: A sample slicing device, see Figures 1 to 3 , including a device bottom plate 1, and also including: two grooves 202, the two grooves 202 are respectively opened on both sides of the top of the device bottom plate 1; an anti-sticking mechanism, fixed in the two grooves 202, the anti-sticking mechanism includes a first fixed cylinder 203, the first fixed cylinder 203 is fixed to the bottom end inside the groove 202, the top of the first fixed cylinder 203 is penetrated by a second fixed cylinder 206, one end of the second fixed cylinder 206 located in the first fixed cylinder 203 is fixed with a connecting plate 205, a spring 204 is fixed at the bottom of the connecting plate 205, the first fixed cylinder 203 is fixed at the bottom of the spring 204, and a pressing plate 2 is fixed on the top of the second fixed cylinder 206; a scraping groove 201 is opened in the middle of the top of the pressing plate 2, the sample is first placed on the top of the pushing plate 215, because the spring 204 is arranged inside the first fixed cylinder 203, the second fixed cylinder 206 and the pressing plate 2 can be driven to move downward through the elastic force of the spring 204, so that the pressing plate 2 is fitted with the top of the sample, and after the fitting is completed, it can be opened The second electric telescopic cylinder 102 is opened, and the second electric telescopic cylinder 102 will drive the cutting blade 103 to move downward, so that the cutting blade 103 passes through the scraping groove 201 on the top of the pressing plate 2 to slice the sample. After the sample is sliced, the cutting blade 103 will move upward through the scraping groove 201, and the sticky sample on the surface of the cutting blade 103 will be scraped off through the scraping groove 201. Since the pressing plate 2 is fitted and limited to the sample, the cutting blade 103 will not drive the sticky sample to move upward during the upward movement, causing damage to the sample, which solves the technical problem that there is a certain distance between the placement plate and the scraper in the traditional sample slicing device. When the blade moves upward, although the sample on the surface of the blade is scraped off by the scraper, the sample will also move upward during the upward movement of the sticky sample. Even if the scraper can scrape the sample, since the sample is at a certain height from the placement plate after moving up, the sample will fall to the top of the placement plate, causing damage to the sample surface.

[0024] For details, see Figure 2 A slot 207 is provided in the middle of the top of the bottom plate 1 of the device, and a first slot and a second slot 208 are provided on both sides of the slot 207, and a motor 209 is installed in the second slot 208. A motor shaft 210 is connected to one side of the motor 209, and a threaded rod 211 is fixed to the end of the motor shaft 210 away from the motor 209. A moving block 212 passes through the outer side of the threaded rod 211, and the threaded rod 211 is threadedly connected to the screw hole in the moving block 212. When the position of the sample needs to be adjusted, the motor 209 can be opened, and the motor 209 The motor shaft 210 is driven, the motor shaft 210 drives the threaded rod 211, the threaded rod 211 drives the moving block 212, and the moving block 212 drives the first electric telescopic cylinder 213 and the push plate 215 to move, so as to adjust the position of the sample, so as to use the cutting blade 103 to slice different positions of the sample, and because the first electric telescopic cylinder 213 is provided on the top of the moving block 212, the push plate 215 can be driven to move upward through the first electric telescopic cylinder 213, so that samples of different heights can be fitted with the pressing plate 2.

[0025] For further information, see Figure 2 A first electric telescopic cylinder 213 is installed on the top of the moving block 212, a push plate 215 is fixed on the top of the first electric telescopic cylinder 213, a limit rod 214 passes through the bottom end of the moving block 212, and grooves 207 are fixed on both sides of the limit rod 214.

[0026] It is worth noting that see Figure 3 An L-shaped fixing plate 101 is fixed to one side of the top of the device bottom plate 1, and a second electric telescopic cylinder 102 is installed to one side of the top of the L-shaped fixing plate 101.

Since the conduction plate 303 is arranged inside the cutting blade 103, vibration is generated by the vibration motor 301, and the vibration can be transmitted to the conduction plate 303 and the cutting blade 103, so that the cutting blade 103 generates vibration after cutting, thereby vibrating the sticky sample from the blade, which can assist in dealing with the problem of the sample sticking to the surface of the cutting blade 103.

[0027] It is worth noting that see Figure 1 A square hole 104 is opened in the middle of the front end of the device bottom plate 1, and the square hole 104 is connected to the groove body 207, and an observation window 105 is fixed inside the square hole 104.

[0028] It is worth mentioning that see Figure 1An industrial control computer 106 is installed in the middle of one side of the L-shaped fixing plate 101.

[0029] When using a sample slicing device, the sample is first placed on the top of the push plate 215.

After the sample is sliced, the cutting blade 103 will move upward through the scraping groove 201, and the sticky sample on the surface of the cutting blade 103 will be scraped off through the scraping groove 201. Since the pressing plate 2 is fitted and limited to the sample, the cutting blade 103 will not drive the sticky sample to move upward during the upward movement, causing damage to the sample. When the position of the sample needs to be adjusted, the motor 209 can be turned on. The motor 209 drives the motor shaft 210, the motor shaft 210 drives the threaded rod 211, the threaded rod 211 drives the moving block 212, and the moving block 212 drives the first electric telescopic cylinder 213 and the push plate 215 to move, so as to adjust the position of the sample, so as to slice the sample at different positions using the cutting blade 103. Moreover, since the first electric telescopic cylinder 213 is arranged on the top of the moving block 212, the push plate 215 can be driven to move upward through the first electric telescopic cylinder 213, so that samples of different heights can be fitted with the pressing plate 2. Since the conduction plate 303 is arranged inside the cutting blade 103, vibration is generated through the vibration motor 301, and the vibration can be transmitted to the conduction plate 303 and the cutting blade 103, so that the cutting blade 103 generates vibration after cutting, so as to vibrate the sticky sample away from the blade, which can assist in dealing with the problem of the sample sticking to the surface of the cutting blade 103.
