Description

Technical Field

[0001] The utility model relates to the technical field of pathological sections, in particular to a pen-shaped brush for pathological sections. Background Art

[0002] The process of making pathological sections includes ten steps: sampling, fixation, dehydration, transparency, waxing, embedding, slicing, pasting, staining and sealing. In actual work, sampling and fixation are generally not carried out in the same space as dehydration. Therefore, the improvement of pathological section efficiency mainly takes into account the dehydration, transparency, waxing, embedding, slicing, pasting, staining and sealing.

[0003] Patent document CN218916975U discloses a paraffin-embedded pathology section and slide-spreading machine, which realizes the three links of embedding, slicing and slide-spreading in one machine. Although the machine combines the three functions of embedding, slicing and slide-spreading, it also squeezes the working space of embedding, slicing and slide-spreading. Its design purpose is to complete the three links of embedding, slicing and slide-spreading by one person, so the equipment is generally suitable for small-scale pathology section laboratories. Since the equipment deviates from the needs of modern industrial division of labor, it is not conducive to improving the efficiency of pathology sectioning.

[0004] Observe the working process of the pathology section laboratory. The sectioning station is equipped with a skilled worker who uses a hand-cranked slicer, and the patching station is equipped with an assistant. The workload of a skilled pathology section worker in half a day is generally to cut 250 to 350 embedded blocks. There are four key points that affect efficiency: first, the slicer needs to operate the slices by hand; second, the slicer needs to trim the surface of the embedded block, and this process generally produces a large amount of wax scraps; third, after the embedded block section is processed, the slicer needs to use a brush to clean the wax accumulation on the surface of the pathology section guide in time; fourth, after the slicer cuts out the pathology section, it is necessary to use a brush to roll up the pathology section, select the appropriate pathology section, and then use a camera to capture the appropriate pathology section and put it into the slide sink. Then the assistant picks up the pathology section with a slide. It can be seen that the efficiency of pathology sectioning is stuck at the sectioning station.

[0005] In some paraffin-embedded pathological slices and slides, similar to the patent document CN218916975U, the two links of slicing and slides are realized in one machine. The embedded block is sliced ​​by an automatic feeding slicer. After the cutter cuts out the pathological slice, the pathological slice formed later pushes the pathological slice in front to the pathological slice conveyor under the surface of the pathological slice guide. The running water on the pathological slice conveyor drives the pathological slice to flow into the slide water tank, and the patch station needs to hold a slide to find and pick up the appropriate pathological slice. Although the slicing station can be omitted in this device, the slicing speed of the automatic feeding slicer is fast, and a large number of pathological slices float on the water surface in disorder after entering the slide water tank. When the patch station finds and picks up the appropriate pathological slice, it is also necessary to dispose of the discarded pathological slice in time. Because the surface of the slide water tank is too small, and the selection operation needs to be performed, this work is generally completed by one person. Although the slicing efficiency of the embedded block is improved, the card point affecting the efficiency of pathological slices is transferred to the patch station.

[0006] After comprehensive analysis, it was found that: first, choosing an automatic feeding slicer can improve the efficiency of pathology slicing; second, if a brush can be used to roll up the pathology slices faster, it can also improve the efficiency of pathology slicing. Summary of the invention

[0007] Considering that in the pathology section laboratory, the section worker uses a writing brush for two purposes: the first is to clean the surface of the pathology section guide table, and the second is to roll up and attach the pathology section. Therefore, the purpose of the utility model is to provide a pen-shaped brush for pathology section, so as to improve the efficiency of the tool in collecting and attaching pathology sections while taking into account the cleaning function.

DETAILED DESCRIPTION

[0024] The present invention is described in the form of embodiments in conjunction with the accompanying drawings to assist those skilled in the art in understanding and implementing the present invention. Unless otherwise specified, the following embodiments and the technical terms therein should not be understood without the technical knowledge background of the present technical field.

[0025] Embodiment 1: A pen-shaped brush for pathological sections comprises an air extraction device 21 , a breathable medical waste filtering device 22 , a hose 23 and a pen-shaped brush body 1 .

[0026] See also Figure 1—3, the pen-shaped brush body 1 is connected by a hose connector 15, a pen holder 11 and an air suction brush head 12. The pen holder 11 is provided with a pen holder inner tube 10. The pen holder is provided with a pen holder inner tube, so that the pen-shaped brush body is easier to hold. The air suction brush head 12 is provided with a trachea 125 and a plurality of air suction branches 121 connected to the trachea 125 pipeline, and the air suction branches 121 form an opening on the side of the air suction brush head. The reason why the air suction branch 121 forms an opening on the side of the air suction brush head is that the part where the pathological section is collected by the pen-shaped brush for pathological section is mainly on the side of the air suction brush head, not on the end face of the air suction brush head. Of course, the opening of the air suction branch 121 can also be provided on the end face of the air suction brush head, so that even if the pathological section is adsorbed on the air suction brush head, the opening of the air suction branch 121 on the end face of the air suction brush head will not be blocked, and the negative pressure pulling on the pathological section will not be too large, which can reduce the damage to the pathological section. The suction brush head 12 is fixedly connected to one end of the pen shaft 11, and the other end of the pen shaft 11 is fixedly connected to the hose connector 15, and the trachea 125, the inner tube 10 of the pen shaft and the pipeline in the hose connector 15 are connected to form a pipeline. After the suction device 21 is started, the suction device 21 sucks the air outside the suction brush head 12 into the pipeline and discharges it through the pipeline section formed by the breathable medical waste filter 22, the pipeline section formed by the hose 23, the pipeline section formed by the hose connector 15, the inner tube 10 of the pen shaft, the trachea 125, and the suction branch pipe 121. In this way, negative pressure will be formed outside the suction brush head 12. When the suction brush head is operated close to the pathological section, it is easier to collect the pathological section than using a brush to roll up the pathological section.

[0027] Preferably, the hose connector 15 is detachably connected to the hose 23. This makes storage more convenient and also facilitates expanding the number of pen holders connected to the breathable medical waste filtering device.

[0028] During the operation of the vacuum device 21, wax scraps, tissues, etc. outside the suction brush head 12 will also be sucked into the pipeline. The breathable medical waste filter device 22 arranged on the pipeline will filter and concentrate wax scraps, tissues, etc. while allowing gas to pass through, thus meeting the biosafety requirements of medical equipment. Breathable medical waste filter devices that meet such requirements can be found in Figure 4 The structure shown.

[0029] See also Figure 4The breathable medical waste filtering device 22 comprises a sealed tank 221, which is used to hold the filtrate. When in use, a gas storage space is provided between the filtrate and the inner top wall of the sealed tank 221. The filtrate can use medical ethanol, so that in addition to filtering, it can also have a disinfection effect. The air suction port 222 is extended and arranged at a position of the sealed tank 221 that is connected to the gas storage space, and is preferably arranged on the inner top wall of the sealed tank 221. The air replenishment port 223 is extended and arranged in the filtrate through an extension tube 224, so that the filtrate can play a filtering role. Generally, in order to facilitate the addition of the filtrate, a liquid adding port can be provided on the sealed tank 221, and a sealing cover can be detachably connected to the liquid adding port. Generally, in order to facilitate the observation of the amount of the filtrate in the sealed tank 221, a liquid level gauge can be provided on the sealed tank 221, or a vertical strip transparent observation window can be formed on the shell of the sealed tank 221. The specific principle is: when the air suction device is working, the gas in the gas storage space is sucked out, and the air pressure in the gas storage space is lower than the atmospheric pressure. The air pressure in the hose 23 and the pen inner tube 10 is close to atmospheric pressure, so the air in the hose 23 and the pen inner tube 10 is replenished into the air storage space, and then the air pressure in the hose 23 and the pen inner tube 10 is reduced, and the air pressure outside the suction brush head 12 is atmospheric pressure, which is replenished into the hose 23 and the pen inner tube 10 through the suction branch pipe 121 and the air pipe 125, thus realizing the flow of gas and the passage of gas in the breathable medical waste filtering device 22. The air suction port 222 is connected to the air suction port of the suction device 21 through a pipeline, and the air replenishment port 223 is connected to one end of the hose 23. Although there is a hose in the pipeline connected to the air suction port of the suction device 21, and the hose will be deformed when there is negative pressure, by controlling the negative pressure and selecting the material and wall thickness of the hose, the hose can be made to achieve both soft connection and keeping the pipeline unobstructed under negative pressure. See Figure 4 For the convenience of maintenance, a sealed tank 221 can be made of a tank body, a tank cover and a sealing member. A pipe joint can be detachably connected to the air extraction port 222, and a pipe joint with an extension pipe 224 can also be detachably connected to the air supply port 223.

[0030] At present, threaded connection can meet the needs of detachable connection. Sealing thread has a certain sealing effect, and with the help of sealing parts, it can fully meet the sealing requirements of pipeline connection.

[0031] See also Figure 2—3. In this embodiment, the air suction brush head 12 includes an air suction head 124 and brush hairs 13. The air suction head 124 is fixedly connected to the pen holder 11. There are multiple air suction branches, and multiple air suction ports are distributed on the side surface of the air suction head 124. Multiple brush hairs 13 are scattered and arranged on the side of the air suction head 124. One end of the brush hairs 13 is fixedly connected to the pen holder 11, and the other end of the brush hairs 13 protrudes from the air suction head 124 to form brush hairs. Such an air suction brush head is not easy to harbor dirt and is easy to clean. The brush hairs are scattered and arranged on the side of the air suction head, which can not only disperse the suction force at the air suction port, but also buffer the speed of the pathological section approaching the air suction port, thereby reducing the degree of damage to the pathological section.

[0032] To make it easier to straighten the bristles so that the free ends converge, see Figure 3 , a conical section 122 is provided on the suction brush head 12, and the conical section 122 has a conical end adjacent to the suction head 124. One end of the brush hair 13 is attached to the side of the conical section 122, and the brush hair bundling part 14 embraces the brush hair 13 on the circumference of the conical section to fix one end of the brush head 13 on the pen holder. In order to enhance the fixing effect, a protrusion can be placed on the conical section 122 to form an anti-slip limiter 123. At the connection between the suction head and the conical section 122, the cross-sectional periphery of the suction head is preferably arranged within the periphery of the conical section 122. In this way, a gap can be formed between the brush hair and the suction port on the suction head, so that the brush hair has a better buffering effect on the obstruction of the pathological section, and the dispersion effect will also be better when the airflow flows through the brush hair.

[0033] In other embodiments, the suction brush head may also use such a structure: the suction brush head is coated on the suction end of the trachea with a porous soft brush head. The inner hole of the porous soft brush head is an open hole structure, so that multiple inner holes are connected to form multiple suction branches, and multiple suction ports are distributed on the surface of the porous soft brush head. A sponge brush head is a porous soft brush head. When the sponge brush head is coated on the suction end of the trachea, the connected openings in the sponge brush head form the suction branches. Such a suction brush head has a low manufacturing cost.

[0034] In this embodiment, the air extraction device includes an air extraction pump. Figure 5 The vacuum pump is driven by a DC motor, and the power supply can be a low-voltage power supply, which is safe. The key switch can be set on the pen holder or the vacuum pump control as needed. Generally, in large laboratories, more attention is paid to operational convenience. During work, the vacuum pump is in a normally open state. According to needs, a stop valve can be set on the pen holder or the pipe between the pen holder and the air supply port.

[0035] The utility model is described in detail above with reference to the accompanying drawings and embodiments. It should be understood that it is impossible to describe all possible implementation methods in practice, and the inventive concept of the utility model is described as much as possible by way of example. Without departing from the inventive concept of the utility model and without creative work, the technical personnel in this technical field make selections and combinations of the technical features in the above embodiments, experimental changes to the specific parameters, or use the prior art in this technical field to conventionally replace the disclosed technical means of the utility model to form specific embodiments, which should all belong to the implicit disclosure of the utility model.
