Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an annular cleaning brush. Background Art

[0002] In hospitals, biopsy forceps are often used to obtain pathological specimens. If the biopsy forceps used are not cleaned thoroughly, it will cause patients to be infected. Therefore, the cleaning of biopsy forceps is very important. Due to the complex structure of biopsy forceps, the forceps body is slender and spiral with internal cavities, which are extremely easy to adhere to organic substances such as mucus and blood, and are liable to form biofilms on the surface, becoming the transmission media of bacteria, HBV, HCV, HIV, etc. The biopsy forceps need to be subjected to multi-enzyme ultrasonic cleaning first and then manual brushing. At present, during manual brushing, a conventional brush is used to brush the forceps body. Each time, only one side of the forceps body can be cleaned, and then it is slowly rotated to other sides for cleaning. The cleaning speed is slow, and during the rotation process, it is easy to miss the cleaning of a certain side, resulting in poor cleaning effect. This is not only applicable to the cleaning of biopsy forceps, but also to other cylindrical instruments that need to clean the outer side. Therefore, it is necessary to set up a cleaning brush that can simultaneously clean the entire outer side of the forceps body, which can improve the cleaning efficiency and the cleaning effect. Content of the Utility Model

[0023] Specific Embodiment 1, as Figures 1-5 shown, is a preferred embodiment of the present utility model. An annular cleaning brush includes a first fixing block 4 and a second fixing block 8. Both the first fixing block 4 and the second fixing block 8 are semi-cylindrical columns. The first fixing block 4 and the second fixing block 8 are hinged to form a cylindrical structure. A first handle 1 is installed on the outer side surface of the first fixing block 4, and a second handle 9 is installed on the outer side surface of the second fixing block 8. The first handle 1 and the second handle 9 are rotationally connected through a rotating shaft, and a torsion spring is installed on the rotating shaft. The first fixing block 4 and the second fixing block 8 are clamped under the action of the torsion spring. A sliding groove is formed on the inner side surface of the first fixing block 4, and a semi-cylindrical brush block 6 is slidably connected in the sliding groove. The brush block 6 slides towards the axis side of the first fixing block 4. A plurality of first springs 10 are installed between the first fixing block 4 and the brush block 6, and the axes of the plurality of first springs 10 all point to the axis of the brush block 6. An elastic card 5 is installed at the notch of the sliding groove, and the brush block 6 is clamped in the sliding groove; a plurality of first bristles 13 are installed on the inner side surface of the brush block 6. A cavity is provided inside the brush block 6, and an adjusting structure is installed in the cavity. A plurality of uniformly distributed pores are formed on the inner side surface of the brush block 6, and a second bristle 12 is installed on the adjusting structure. The second bristle 12 extends out of the brush block 6 through the pores, and the distance that the second bristle 12 extends out of the pores is adjusted by the adjusting structure; the structures of the first fixing block 4 and the second fixing block 8 are the same. When the first fixing block 4 and the second fixing block 8 are clamped, the first bristles 13 on the two brush blocks 6 form a first annular brush, and the second bristles 12 on the two brush blocks 6 form a second annular brush.

[0024] During the specific use of the utility model, the brush block 6 is first installed in the slide grooves of the first fixed block 4 and the second fixed block 8 respectively, and the brush block 6 is clamped in the first fixed block 4 and the second fixed block 8 by the elastic card 5 on the slide groove, so that the brush block 6 will not fall off. Furthermore, a plurality of first springs 10 are installed between the brush block 6 and the first fixed block 4, and between the brush block 6 and the second fixed block 8. Under the elastic force of the first spring 10, the brush block 6 abuts against one side of the notch of the slide groove, so that the first bristles 13 on the two brush blocks 6 can be closely attached to the outer side of the equipment to be cleaned. Furthermore, a plurality of limiting columns are provided on the inner side of the first fixed block 4, and each of the first springs 10 is sleeved on the limiting column, and the length of the limiting column is less than the length of the first spring 10. When the first fixing block 4 and the second fixing block 8 are clamped, the first bristles 13 on the two brush blocks 6 form a first annular brush, and the second bristles 12 on the two brush blocks 6 form a second annular brush. The instrument to be cleaned, such as a biopsy forceps, is clamped between the brush blocks 6 of the first fixing block 4 and the second fixing block 8, and the first annular brush is used to brush the outer side of the biopsy forceps. When cleaning, hold the first handle 1 and the second handle 9, and brush along the length direction of the instrument, and slightly rotate the utility model so that the first annular brush rotates around the axis of the instrument to brush, and the brushing effect is better.

[0025] When the diameter of the instrument to be cleaned is larger than the diameter of the first annular brush, the instrument is clamped between the brush blocks 6 of the first fixed block 4 and the second fixed block 8, and the first spring 10 is compressed to spread the two brush blocks 6 apart, but the first fixed block 4 and the second fixed block 8 remain clamped, so that the diameter of the first annular brush formed by the first bristles 13 of the two brush blocks 6 becomes larger and still covers the outside of the instrument to be cleaned.

[0026] When the diameter of the instrument to be cleaned is smaller than the diameter of the first annular brush, the length of the second bristles 12 extending out of the brush block 6 is adjusted by the adjustment structure installed in the brush block 6, so that the outer ends of the second bristles 12 exceed the outer ends of the first bristles 13, and a second annular brush is formed by the second bristles 12 on the two brush blocks 6. The diameter of the second annular brush is smaller than the diameter of the first annular brush, thereby facilitating the cleaning of instruments with a diameter smaller than the first annular brush and larger than the second annular brush.

[0027] Further, the adjusting structure mainly includes a semi-circular brush plate 16, which is slidably connected in the cavity. The brush plate 16 slides towards the axis side of the first fixing block 4. A plurality of second springs are installed in the cavity, and the axes of the plurality of second springs all point to the axis of the brush block 6. A plurality of second bristles 12 are installed on the inner plate surface of the brush plate 16. When the second springs are in the natural state, the outer ends of the second bristles 12 do not extend beyond the outer ends of the first bristles 13. A first wedge block 15 is installed on the outer plate surface of the brush plate 16. A jack is formed in the brush block 6, and the jack penetrates through the brush block 6. The axis of the jack is parallel to the axis of the brush block 6. A plug rod 3 is inserted into the jack. A stop block 11 is installed at one end of the plug rod 3. A third spring is sleeved on the plug rod 3, and the third spring is installed between the stop block 11 and the upper end surface of the brush block 6. The lower end of the plug rod 3 is threadedly connected with a fastening nut 2, and the fastening nut 2 abuts against the lower end surface of the brush block 6. A second wedge block 14 is installed on the plug rod 3. The directions of the first wedge block 15 and the second wedge block 14 are opposite. When the second wedge block 14 presses the first wedge block 15, the brush plate 16 slides towards the inner side of the brush block 6, the second springs are in the stretched state, and the outer ends of the second bristles 12 extend beyond the outer ends of the first bristles 13.

[0028] The diameter of the second annular brush is adjusted by adjusting the position of the brush plate 16 inside the brush block 6. By tightening the fastening nut 2, the second wedge block 14 on the plug rod 3 continuously presses against the first wedge block 15 on the outer plate surface of the brush plate 16, causing the brush plate 16 to move towards the axis side of the first fixing block 4. The second springs are stretched, causing the second bristles 12 installed on the inner plate surface of the brush plate 16 to continuously extend from the pores on the brush block 6, so that the outer ends of the second bristles 12 extend beyond the ends of the first bristles 13, making the diameter of the second annular brush formed by the second bristles 12 smaller than that of the first annular brush. The second bristles 12 of the second annular brush contact the outer side surface of the instrument to be scrubbed, and the second annular brush is used for scrubbing. When the second annular brush is not needed, loosen the fastening nut 2. Under the limiting action of the fastening nut 2 and the action of the third spring, the position of the plug rod 3 is fixed, and the second wedge block 14 on the plug rod 3 does not press the first wedge block 15. Under the action of the second springs, the brush plate 16 moves towards the outer side surface of the first fixing block 4, and the second bristles 12 are retracted, and the outer ends of the second bristles 12 do not extend beyond the ends of the first bristles 13. During cleaning, the first annular brush can be used for cleaning. When the outer ends of the second bristles 12 are flush with the first bristles 13, the first annular brush and the second annular brush can be used simultaneously for cleaning, with denser bristles and better cleaning effect.

[0029] Further, the first bristles 13 and the second bristles 12 are made of mildew-proof materials to reduce the growth of mildew on the bristles after long-term use.

[0030] Further, the first bristles 13 and the second bristles 12 are made of soft brushes, which can be deformed to brush the gaps and are not easy to wear the instruments.

[0031] Further, anti-slip patterns are provided on both the first handle 1 and the second handle 9 to reduce the phenomenon of slipping during the brushing process.

[0032] Further, drain holes 7 are provided on the brush block 6. When brushing, liquid may enter the cavity of the brush block 6 from the pores, and the drain holes 7 can drain the water in the cavity to reduce the growth of bacteria.

[0033] Specific Embodiment Two, as Figure 6 shown, on the basis of Specific Embodiment One, only the adjustment structure is changed. The adjustment structure mainly includes a brush plate 16, the brush plate 16 is slidably connected in the cavity, the brush plate 16 slides towards the axis side of the first fixing block 4, a plurality of second springs are installed in the cavity, and the axes of the plurality of second springs all point to the axis of the brush block 6. A plurality of second bristles 12 are installed on the inner plate surface of the brush plate 16. When the second springs are in the natural state, the outer ends of the second bristles 12 do not extend beyond the outer ends of the first bristles 13; a first connection hole is provided on the first fixing block 4, and a second connection hole is provided on the brush block 6. The second connection hole communicates with the cavity. When the brush block 6 is clamped in the first fixing block 4, the axes of the first connection hole and the second connection hole coincide. A stud 17 is threadedly connected to the first connection hole, the stud 17 passes through the second connection hole, and when the end of the stud 17 abuts against the outer plate surface of the brush plate 16, the brush plate 16 slides towards the inner side surface of the brush block 6, and the second spring is in a stretched state, and the outer ends of the second bristles 12 extend beyond the outer ends of the first bristles 13.

[0034] When it is necessary to adjust the diameter of the second annular brush, rotate the stud 17 so that the stud 17 continuously abuts against the outer plate of the brush plate 16, so that the brush plate 16 moves towards the axis direction of the first fixing block 4, and the second spring is stretched, so that the second bristles 12 on the brush plate 16 continuously extend outwards from the pores, thereby adjusting the diameter of the second annular brush and facilitating the cleaning of instruments with a diameter smaller than the first annular brush and larger than the second annular brush. When the second annular brush is not in use, rotate the stud 17 so that the stud 17 no longer abuts against the outer plate surface of the brush plate 16. Under the action of the second spring, the brush plate 16 moves towards the outer side surface direction of the first fixing block 4, and the second bristles 12 are retracted so that the outer ends of the second bristles 12 do not extend beyond the ends of the first bristles 13.

[0035] The above description is a detailed description of the preferred and feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the scope of the patent covered by the present invention.
