Description

Technical Field

[0001] The utility model belongs to the technical field of medical detection and relates to a cleaning cover of a pathological slicer. Background Art

[0002] The clinician takes the biopsy tissue for microscopic examination from the patient, and the pathologist performs a series of operations on the biopsy tissue, including fixation, sampling, dehydration, transparency, waxing, embedding, slicing, pasting, baking, staining and sealing. In the above operation process, slicing is one of the most important steps, and its quality directly affects the effect of the pathologist's reading. When slicing, not only the specimen type, size, and thickness must be considered, but also the convenience and comfort of the operator. Usually, a microtome is selected for slicing. The operator performs daily maintenance on the microtome according to the instrument requirements to eliminate the factors affecting slicing in order to achieve the best effect.

[0003] Conventional methods for removing slicer debris are as follows: 1. Blowing method, that is, using a hair dryer and a brush to clean wax debris and some tissue debris every day. The defect is that the operation is time-consuming, and due to different habits of operators, it cannot be completely cleaned, and dead corners and stubborn wax debris and some tissue debris are easily left. At the same time, excessive wind force of the hair dryer may cause wax debris or tissue debris to fly around and contaminate other specimens or reagents on the laboratory table; 2. Melting method, after disassembling the slicer knife seat, put it in an oven and bake it at about 65 degrees for 1-2 hours. After the paraffin automatically melts and flows out, wipe it clean. The defect is that the disassembly process of the slicer knife seat is cumbersome, and it takes a lot of time to carry it back and forth and heat it in the oven. In addition, the oven baking cleaning can only clean the residual wax debris on the knife seat, and the residual wax debris on the desktop needs to be cleaned again. Therefore, the utility model provides a pathology slicer cleaning cover to solve the above problems. Utility Model Content

[0029] After slicing is completed, the slicer needs to be cleaned. Usually, after slicing, the pathology technician needs to use a brush to brush off the waste wax slices and waste wax block debris generated during slicing. Due to the particularity of the knife seat material and the viscosity of the wax and other factors, it is not recommended to use metal tools to forcefully scrape away. Therefore, pathology laboratories currently often use a brush in combination with a hair dryer to clean the wax debris. This process consumes manpower and time. Therefore, the utility model provides a pathology slicer cleaning cover, which can quickly clean the wax debris without wasting manpower.

[0030] like Figure 1 and 2 As shown, a cleaning cover of a pathology slicer comprises a first cover body (1), the first cover body (1) is in the form of a hemispherical body, and a second cover body (2) is provided on the outside of the first cover body (1), and the two have the same shape; a first air hole (1a) is provided on the top of the first cover body (1), and a plurality of second air holes (1b) are symmetrically provided on the side; a dust collection component is provided in a receiving space formed between the first cover body (1) and the second cover body (2), and the dust collection component comprises a vacuum pump (3), a plurality of air pipes (3a) and a chip collection box (4); a motor is provided on the outside of the vacuum pump (3), and the motor is electrically connected to the vacuum pump (3) and the air cooler (7), respectively; and the plurality of air pipes (3a) are used to connect the first air hole (1a) and the chip collection box (4), the second air hole (1b) and the chip collection box (4), and the vacuum pump (3) and the chip collection box (4), respectively.

[0031] A cover body (4a) is provided on the top of the chip collecting box (4), and the two are movably connected via a hinge. Figure 3As shown, a first filter screen (5) and a second filter screen (6) are provided inside the chip collecting box (4), and the first filter screen (5) and the second filter screen (6) are arranged in a sloped manner; Figure 4 As shown, replaceable wax-absorbing paper (8) is provided on the surface of the first filter screen (5) and the second filter screen (6), and the replaceable wax-absorbing paper (8) is provided with a plurality of dense ventilation holes; the first filter screen (5), the second filter screen (6) and the wax-absorbing paper (8) are movably connected via a pressure strip (9).

[0032] An air cooler (7) is provided outside the second cover body (2), and a pipeline (7a) is provided on the side of the air cooler (7). The pipeline (7a) passes through the second cover body (2) and is connected to the first cover body (1). Specifically, a plurality of air inlet holes (1c) are symmetrically provided on the side of the first cover body (1), and the air inlet holes (1c) are located below the second air holes (1b). The pipeline (7a) is connected to the air inlet holes (1c) and is used to blow cold air into the first cover body (1) appropriately, so as to prevent wax scraps on the slicer and the desktop from melting and adhering to the sliced ​​samples and equipment.

[0033] The bottom of the first cover body (1) and the second cover body (2) are both provided with a sealing ring (10), the sealing ring (10) being in a circular ring shape, and having two annular grooves (10a) on the top thereof, the two annular grooves (10a) being used to clamp the lower edges of the first cover body (1) and the second cover body (2) respectively, so as to fix the distance between the two. At the same time, when it is necessary to disassemble and replace the wax absorbing paper (8), the sealing ring (10) is removed and the chip collecting box (4) is taken out. The sealing ring (10) is made of soft PVC material. The surfaces of the first cover body (1) and the second cover body (2) are both provided with regular corrugated folds, and both can be folded and stored. Specifically, the first cover body (1) and the second cover body (2) are made of PP or ABS soft material.
