Description

Technical Field

[0001] This invention relates to the field of pathological consumables and instruments, specifically to a tissue cleaning brush. Background Technology

[0002] The pathology department needs to cut a large number of tissue blocks every day (including paraffin-embedded tissue blocks and frozen tissue blocks). After each tissue block is rough and finely trimmed, a large amount of paraffin debris and tissue fragments are left on the slide holder. How to quickly clean up, decontaminate and disinfect the tissue fragments is a challenge for pathology technicians.

[0003] 1. Current Practices

[0004] Most pathology technicians repeatedly use brushes or pen to clean tissue debris when cutting sections: after picking up a paraffin block / tissue block for sectioning, a large amount of pathological tissue debris will be left on the scalpel table after rough and fine trimming. If not cleaned in time, the tissue debris will stick to the target pathological tissue slide and cause contamination. Therefore, after cutting each paraffin block / tissue block, it is necessary to sweep it with a brush or pen once or multiple times. However, during the sweeping process, small paraffin debris can easily enter the gaps of the brush or pen, causing contamination.

[0005] 2. Major defects

[0006] When cleaning with a brush or pen, fine tissue debris cannot be cleaned properly, and the blade can easily be damaged, leading to dulling and nicks. Since hundreds or even thousands of wax blocks / tissue blocks are cut every day, the reuse of brushes or pen can easily lead to contamination of pathological tissues, especially during rapid freezing and slide preparation during surgery, which can easily cause cross-contamination.

[0007] Existing technologies cannot achieve integrated cleaning and disinfection, and cannot simultaneously remove pathological tissue debris and disinfect in a single operation. Summary of the Invention

[0008] To address the problems existing in the prior art, the present invention provides a disposable multi-layer sterile gauze pen-shaped brush for pathological tissue sectioning scalpel holder, which solves at least one of the above-mentioned technical problems.

[0009] The technical solution of the present invention is: a disposable multi-layer sterile gauze pen-shaped brush for a pathological tissue sectioning scalpel holder, characterized in that it includes a sterile liquid injection pen, a connector, and sterile gauze;

[0010] The disinfectant injection pen includes an injection cylinder, an injection nozzle at the end of the injection cylinder, and a one-way valve inside the injection nozzle.

[0011] The connector is shaped like a frustum of a cone with an outer diameter that increases from the side adjacent to the disinfectant injection pen to the side away from the disinfectant injection pen. A through hole is provided in the center of the connector to pass through the injection nozzle. The connector is detachably connected to the end of the disinfectant injection pen.

[0012] The sterile gauze comprises a circular gauze made of three layers of gauze stacked together. A silicone guide tube is fixed to the inner side of the circular gauze. The center of the silicone guide tube is connected to the injection nozzle. The silicone guide tube has a permeation hole for facing the circular gauze.

[0013] The sterilizing gauze and the connector are detachably connected.

[0014] This invention uses a disinfectant injection pen to moisten a sterile gauze, and then uses the sterile gauze to wipe tissue debris from the scalpel holder in one direction.

[0015] This invention ensures the support surface of the gauze by using a joint.

[0016] More preferably, the disinfectant injection pen further includes a piston that is slidably disposed inside the injection cylinder, the piston being connected to a piston rod, and a positioning element arranged along the axial direction being detachably connected to the piston rod;

[0017] By sequentially removing the axially arranged positioning components, different positioning components are sequentially abutted against the injection cylinder, thereby achieving quantitative extrusion of liquid from the injection cylinder.

[0018] More preferably, the silicone guide tube includes circumferentially arranged sub-tubes, all of which extend radially, and the ends of all the sub-tubes are connected to each other, with the connection point of all the sub-tubes being the center of the silicone guide tube.

[0019] More preferably, the radial outer side of the sub-tube is sealed.

[0020] More preferably, an elastic sleeve is provided on the outer side of the circular gauze, and the elastic sleeve is fitted around the periphery of the connector.

[0021] This facilitates the detachable connection between the connector and the sterilized gauze.

[0022] More preferably, the elastic sleeve includes a cylindrical gauze sleeve, one end of which is fixedly connected to the outer edge of the circular gauze, and the other end of which is fixed with an elastic ring.

[0023] More preferably, the disinfectant gauze further includes a waterproof layer, which is located inside the silicone drainage tube;

[0024] The waterproof layer includes two symmetrically arranged waterproof fabrics, one end of which is connected to the outer edge of the circular gauze, and elastic bands are fixed to the adjacent sides of the two waterproof fabrics.

[0025] More preferably, after the elastic sleeve is turned outwards, the elastic sleeve and the circular gauze form a storage bag for collecting debris.

[0026] After tidying up, fold the circular gauze in half, flip the waterproof layer on one side in the opposite direction, and wrap the circular gauze with the waterproof layer.

[0027] More preferably, the circular gauze comprises, from the inside out, a microfiber cloth, a degreased gauze, and a microfiber dust-free cloth.

[0028] It allows for easy penetration of the disinfectant solution, followed by wiping with a microfiber lint-free cloth for disinfection.

[0029] More preferably, a cross-shaped silicone valve is installed in the center of the silicone guide tube.

[0030] It facilitates the insertion of the injection nozzle, and when the injection nozzle is removed, it closes naturally through the cross-shaped silicone valve.

[0031] Beneficial effects:

[0032] 1. This invention provides a method for rapid cleaning and disinfection of pathological tissue debris on a pathological tissue sectioning scalpel and scalpel holder tissue table.

[0033] 2. This invention solves the problems of incomplete cleaning, low efficiency, high risk of contamination, and easy damage to the blades in existing technologies. It can reduce the cost of pathology slide blades in departments, and at the same time, timely and effective disinfection can reduce biological hazards.

Detailed Implementation

[0040] See Figures 1 to 2 Specific embodiment 1: A disposable multi-layer sterile gauze pen-shaped brush for pathological tissue section scalpel holder, comprising a sterile injection pen 1, a connector 2, and sterile gauze 3; the sterile injection pen 1 includes an injection cylinder 11, with an injection nozzle at the end of the injection cylinder 11, and a one-way valve inside the injection nozzle; the connector 2 is a frustum-shaped cone with an outer diameter increasing from the side adjacent to the sterile injection pen 1 to the side away from the sterile injection pen 1, and a perforation through which the injection nozzle passes through the center of the connector 2; the connector 2 is detachably connected to the end of the sterile injection pen 1; the sterile gauze 3 comprises a circular gauze 32 formed by stacking up to three layers of gauze, with a silicone guide tube 31 fixed to the inner side of the circular gauze 32, the center of the silicone guide tube 31 being connected to the injection nozzle, and a permeation hole for facing the circular gauze 32 on the silicone guide tube 31; the sterile gauze 3 is detachably connected to the connector 2. This invention uses a disinfectant injection pen 1 to moisten a sterile gauze 3, and then uses the sterile gauze 3 to wipe tissue debris from the scalpel holder in one direction. The invention uses a connector 2 to ensure the support surface of the gauze.

[0041] The silicone guide tube 31 includes circumferentially arranged sub-tubes, all of which extend radially and are interconnected at their ends, with the interconnection point of all sub-tubes forming the center of the silicone guide tube 31. The radial outer sides of the sub-tubes are sealed.

[0042] The circular gauze 32 comprises, from the inside out, a microfiber cloth, a degreased gauze, and a microfiber cleanroom cloth. This allows for sequential penetration of disinfectant solution, followed by wiping and disinfection with the microfiber cleanroom cloth.

[0043] A cross-shaped silicone valve is installed in the center of the silicone guide tube 31. This facilitates the insertion of the injection nozzle and allows the valve to close naturally when the nozzle is removed. A mating interface for the injection nozzle is located in the center of the silicone guide tube 31. A cross-shaped silicone valve is installed at this interface. This interface is the inlet end of the silicone guide tube 31, preventing backflow of liquid within the tube. The permeation hole is the outlet end of the silicone guide tube. A cross-shaped silicone valve can be installed at the permeation hole, facilitating the drainage of liquid into the circular gauze.

[0044] See Figure 3In specific embodiment 2, based on specific embodiment 1, an elastic sleeve 33 is provided on the outer side of the circular gauze 32, and the elastic sleeve 33 is fitted around the outer periphery of the connector 2. This facilitates the detachable connection between the connector 2 and the sterilized gauze 3. The elastic sleeve 33 includes a cylindrical gauze sleeve, one end of which is fixedly connected to the outer edge of the circular gauze 32, and the other end of which is fixed with an elastic ring 36. After the elastic sleeve is turned outwards, the elastic sleeve and the circular gauze 32 form a storage bag for collecting debris.

[0045] See Figure 4 In specific embodiment 3, based on specific embodiment 2, the sterilizing gauze further includes a waterproof layer located inside the silicone guide tube. The waterproof layer comprises two symmetrically arranged waterproof fabrics 34, one end of which is connected to the outer edge of the sterilizing gauze sheet. Elastic bands 35 are fixed to adjacent sides of both waterproof fabrics 34. After the elastic sleeve is folded outwards, it and the circular gauze form a storage bag for collecting debris. After storage, the circular gauze is folded in half, and one side of the waterproof layer is flipped inwards to wrap the circular gauze. The silicone guide tube is sandwiched between the circular gauze and the waterproof layer. After the circular gauze is folded in half, along the thickness direction, it consists of a lower silicone guide layer, an upper semi-circular gauze, a lower semi-circular gauze, and an upper silicone guide layer. The reverse flipping of the waterproof layer on one side means that the inner side (lower side in the thickness direction) of the bottom silicone guide layer after the circular gauze is folded in half, and then flipped to the outer side (upper side in the thickness direction) of the top silicone guide layer after the circular gauze is folded in half, and then continues to wrap downwards to cover the bottom silicone guide layer, thus wrapping the folded circular gauze with a single waterproof layer.

[0046] See Figure 1 In specific embodiment 4, based on specific embodiment 2, the disinfectant injection pen further includes a piston 12 slidably disposed inside the injection cylinder. The piston is connected to a piston rod, and a positioning element 13 arranged axially is detachably connected to the piston rod. By sequentially removing the axially arranged positioning elements 13, different positioning elements 13 are sequentially abutted against the injection cylinder 11, thereby achieving quantitative extrusion of liquid from the injection cylinder. The positioning elements can be clamps or positioning pins.

[0047] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
