Description

Technical Field

[0001] This invention relates to the field of instrument cleaning technology, specifically a handheld electric cleaning device suitable for cleaning tubular instruments. Background Technology

[0002] The handheld electric cleaning device for tubular instruments is designed specifically for hospital sterilization supply centers. It is used for handheld electric cleaning of slender tubular instruments such as endoscopes, laparoscopes, and suction tubes. Its core features include flexible shaft drive, rotating brush head, and controllable water flow, replacing manual brushing and improving efficiency and cleaning quality.

[0003] Current methods for cleaning tubular instruments typically involve using water flow combined with a rotating brush head to scrub the inner walls. These instruments are often made of composite materials, with ends made of stainless steel or other metals. Their internal chambers are irregularly shaped, easily accumulating dirt and difficult to clean thoroughly using conventional methods. Currently, cleaning water temperatures are generally controlled between 20 and 40°C, which has limited cleaning power. Increasing the water temperature above 40°C can damage the flexible structural components of the instruments, affecting their lifespan and performance. Therefore, this paper proposes a handheld electric cleaning device suitable for cleaning tubular instruments to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a handheld electric cleaning device suitable for cleaning tubular instruments, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, the handheld electric cleaning device for cleaning tubular instruments includes a handheld instrument cleaning device, a rotating sleeve, and a tubular instrument cleaning component. The handheld instrument cleaning device has a rotating sleeve installed on top, and a lumen cleaning component for cleaning the inside of lumen instruments is installed at the other end of the rotating sleeve. The lumen cleaning device includes a hollow inlet tube and a docking sleeve. The docking sleeve is fixed to one end of the inlet tube, and an electrical conduction tube is also fixedly connected to the end of the docking sleeve facing away from the inlet tube. The surface of the inlet tube has evenly distributed side water holes, and the outside of the inlet tube is fixedly connected with evenly distributed cleaning brushes for cleaning the inner wall of tubular instruments. The inside of the inlet tube is also equipped with a connecting wire. One end of the connecting wire is connected to the circuit conduction tube, and the other end of the connecting wire is fixedly connected to a heating wire. The heating wire is set in a heating groove opened on the side inside the inlet tube, and an insulation sleeve is fixedly connected to the inner wall of the heating groove. One end of the heating tank is provided with a water inlet hole that communicates with the internal chamber of the inlet pipe, and the other end of the heating tank is provided with a drain hole that communicates with the outside of the inlet pipe.

[0006] As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, a through hole is provided on one side of the rotating sleeve, and an electrical conduction tube is provided inside the through hole.

[0007] As an optional solution of the handheld electric cleaning device for cleaning tubular instruments described in this invention, a positioning sleeve is also installed on the outside of the connecting wire, and the positioning sleeve is made of magnetic blocks.

[0008] As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, the cleaning steps are as follows: Step 1: Assemble the docking components: Put the docking sleeve on the outside of the rotating sleeve, insert the circuit tube into the through hole, and then connect the external water pipe to the side of the handheld cleaning device to complete the initial assembly of the whole machine. Step 2: Full-area rotation cleaning: Insert the inlet tube into the instrument cavity to be cleaned, start the handheld instrument cleaning device, drive the rotating sleeve to rotate, and simultaneously drive the docking sleeve and the inlet tube to rotate, so that the cleaning brush on the outside of the inlet tube follows the rotation, and complete the full cleaning of the inner wall of the cavity. Step 3: Targeted Heating Cleaning: Insert the inlet tube into the cavity to be cleaned again, use the external magnetic block to scan along the outer wall of the instrument, and use the positioning sleeve to accurately determine the position of the heating wire and move it to the target area; then turn on the heating wire to perform high-temperature intensive cleaning on the area where dirt has accumulated; Step 4: After the operation is completed, organize and store the entire cleaning device.

[0009] Current methods for cleaning tubular instruments typically involve using water flow combined with a rotating brush head to scrub the inner walls. These instruments are often composite structures, with ends made of stainless steel or other metals. Their irregular internal chambers easily accumulate dirt, making thorough cleaning difficult with conventional methods. Currently, cleaning water temperatures are generally controlled between 20 and 40°C, limiting their cleaning ability. Increasing the water temperature above 40°C can damage the flexible structural components of the instruments, affecting their lifespan and performance. By incorporating connecting wires and heating wires inside the inlet tube, targeted heating cleaning of the stainless steel ends of tubular instruments can be achieved. Using an external magnetic block and positioning sleeve, the heating wires are precisely delivered to the instrument end area. Clean water flows through the inlet tube, enters the insulation sleeve through the inlet hole, is heated by the heating wires, and flows out through the drain hole, completing localized targeted heating cleaning and thoroughly removing accumulated contaminants. The high-temperature water continues to flow forward and mixes with room-temperature water, rapidly cooling the water and preventing damage to the flexible components at the instrument's rear end. The inlet tube is made of flexible material, making it easy to penetrate into various lumens and instruments. The tube wall has evenly spaced side water holes, through which water can flow outwards. Combined with the rotating cleaning brush on the outside, it can achieve a thorough cleaning of the inner wall of the lumen.

[0010] As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, one end of the heating tank is further provided with an annular sleeve installed inside the inlet tube. The annular sleeve is hollow, and the outer side of the annular sleeve is provided with evenly distributed water passage holes. One side of the water passage hole is provided with a drain hole opened on the surface of the inlet tube, and multiple drain holes are provided.

[0011] As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, a sealing sleeve is fixedly connected to the outside of the connecting wire, and the outside of the sealing sleeve is in close contact with the inlet tube.

[0012] The heating wire has an annular sleeve at its end. After the hot water flows into the annular sleeve, it is sprayed outward in an annular pattern through the water passage and drain hole on its side wall, expanding the cleaning coverage area and improving the cleaning effect and work efficiency.

[0013] As an optional embodiment of the handheld electric cleaning device for cleaning tubular instruments described in this invention, a flow-blocking plate is also installed inside the inlet tube, and the flow-blocking plate is inclined.

[0014] An inclined baffle plate is installed inside the inlet pipe to gather and guide the water flow, allowing more water to flow into the heating tank through the inlet hole, thus ensuring stable operation of the fixed-point heating and cleaning process.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The inlet tube has connecting wires and heating wires installed inside its sidewall, allowing for targeted heating and cleaning of the stainless steel ends of instruments. An external magnet and positioning sleeve work together to precisely deliver the heating wire to the instrument end area. Clean water flows through the inlet tube, enters the insulation sleeve through the inlet hole, is heated by the heating wire, and then flows out through the drain hole, completing localized targeted heating and cleaning to thoroughly remove accumulated contaminants. The high-temperature water continues to flow forward and mixes with room-temperature water, allowing for rapid cooling and preventing damage to the flexible components at the instrument's rear end from high temperatures.

After the hot water flows into the annular sleeve, it is sprayed outward in an annular pattern through the water passage and drain hole on its side wall, expanding the cleaning coverage area and improving the cleaning effect and work efficiency.

[0017] An inclined baffle plate is installed inside the inlet pipe to gather and guide the water flow, allowing more water to flow into the heating tank through the inlet hole, thus ensuring stable operation of the fixed-point heating and cleaning process.

Detailed Implementation

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: A handheld electric cleaning device suitable for cleaning tubular instruments includes a handheld instrument cleaning device 1, a rotating sleeve 2, and a tubular instrument cleaning component 3; A rotating sleeve 2 is installed on the top of the handheld instrument cleaning device 1, and a lumen cleaning component 3 for cleaning the inside of lumen instruments is installed on the other end of the rotating sleeve 2. The lumen cleaning device 3 includes a hollow inlet tube 301 and a docking sleeve 302. The docking sleeve 302 is fixed to one end of the inlet tube 301, and an electrical conduction tube 303 is also fixedly connected to the end of the docking sleeve 302 facing away from the inlet tube 301. The surface of the inlet tube 301 is provided with evenly distributed side water holes 305, and the outside of the inlet tube 301 is fixedly connected with evenly distributed cleaning brushes 304 for cleaning the inner wall of tubular instruments. The inside of the inlet tube 301 is also provided with a connecting wire 306. One end of the connecting wire 306 is connected to the circuit conduction tube 303, and the other end of the connecting wire 306 is fixedly connected to a heating wire 309. The heating wire 309 is set in a heating groove opened on the side inside the inlet tube 301, and a heat insulation sleeve 308 is fixedly connected to the inner wall of the heating groove. One end of the heating tank is provided with a water inlet hole 311 that communicates with the internal cavity of the inlet pipe 301, and the other end of the heating tank is provided with a drain hole 312 that communicates with the outside of the inlet pipe 301.

[0022] A through hole 4 is provided on one side of the rotating sleeve 2, and a circuit conduction tube 303 is provided inside the through hole 4.

[0023] A positioning sleeve 310 is also installed on the outside of the connecting line 306, and the positioning sleeve 310 is made of magnetic blocks.

[0024] The cleaning steps are as follows: Step 1: Assemble the docking components: Fit the docking sleeve 302 onto the outside of the rotating sleeve 2, insert the circuit conduction tube 303 into the conduction hole 4, and then connect the external water pipe to the side of the handheld cleaning device 1 to complete the initial assembly of the whole machine. Step 2: Full-area rotation cleaning: Insert the inlet tube 301 into the cavity of the instrument to be cleaned, start the handheld instrument cleaning device 1, drive the rotating sleeve 2 to rotate, and simultaneously drive the docking sleeve 302 and the inlet tube 301 to rotate, so that the cleaning brush 304 on the outside of the inlet tube rotates with it, and complete the full cleaning of the inner wall of the cavity. Step 3: Targeted heating and cleaning: Insert the inlet tube 301 into the cavity to be cleaned again, use the external magnetic block to scan along the outer wall of the instrument, and use the positioning sleeve 310 to accurately determine the position of the heating wire 309 and move it to the target area; then start the heating wire to perform high-temperature intensive cleaning on the area where dirt has accumulated. Step 4: After the operation is completed, organize and store the entire cleaning device.

[0025] Current methods for cleaning tubular instruments typically involve using water flow combined with a rotating brush head to scrub the inner walls. These instruments are often composite structures, with ends made of stainless steel or other metals. Their internal chambers are irregularly shaped, easily accumulating dirt and difficult to clean thoroughly using conventional methods. Currently, cleaning water temperatures are generally controlled between 20 and 40°C, limiting their cleaning ability. Increasing the water temperature above 40°C can damage the flexible structural components of the instruments, affecting their lifespan and performance. The inlet tube 301 incorporates a connecting wire 306 and a heating wire 309 on its side wall, allowing for targeted heating and cleaning of the stainless steel ends of the tubular instruments. An external magnetic block and a positioning sleeve 310 work together to precisely move the heating wire 309 to the instrument end area. Clean water flows through the inner cavity of the inlet tube 301, enters the insulation sleeve 308 through the water inlet 311, is heated by the heating wire 309, and flows out through the drain hole 312, completing targeted heating and cleaning to thoroughly remove accumulated contaminants. The high-temperature water continues to flow forward and mixes with the normal-temperature water, which can quickly cool it down and prevent high-temperature damage to the flexible components at the rear of the device. The inlet tube 301 is made of flexible material, which makes it easy to penetrate into the interior of various tubular instruments. The side water holes 305 are evenly opened on its tube wall, through which water can flow outward. Combined with the rotating brush 304 on the outside, the inner wall of the tube can be thoroughly cleaned. Also includes the following: The side water holes 305 are located on both sides of the heating tank. When the heated water is discharged through the drain hole 312, since both sides are cold water discharged from the side water holes 305, the heated water will mix with water of other temperatures when it flows away from this area, thus achieving rapid cooling and reducing damage to the non-metallic parts of the tube-type device. The circuit conduction tube 303 is inserted into the inlet hole 4, which not only enables circuit conduction, but also ensures that the lumen cleaning component 3 rotates when the rotating sleeve 2 rotates, thereby cleaning the inner wall of the lumen instrument. The positioning sleeve 310 uses a magnetic block. By working with an external magnetic block, it can accurately determine the position of the heating wire 309 and perform targeted heating of the water for cleaning. The device is made of 304 stainless steel, which is basically non-magnetic and magnets can hardly attract it, thus avoiding interference with the magnetic block. The insulation sleeve 308 is set outside the heating wire 309 to ensure that the heating wire stably heats the water and keeps it warm, while preventing the heated water from exchanging heat with the external environment, thus reducing the water temperature and affecting the cleaning effect.

[0026] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5Specifically, one end of the heating tank is also provided with an annular sleeve 313 installed inside the inlet pipe 301. The annular sleeve 313 is hollow, and the outer side of the annular sleeve 313 is provided with evenly distributed water passage holes 314. On one side of the water passage holes 314, there are multiple drain holes 312 opened on the surface of the inlet pipe 301.

[0027] A sealing sleeve 307 is also fixedly connected to the outside of the connecting line 306, and the outside of the sealing sleeve 307 is in close contact with the inlet tube 301.

[0028] The heating wire 309 has an annular sleeve 313 at its end. After the hot water flows into the annular sleeve 313, it is sprayed outward in an annular shape through the water passage 314 and drain hole 312 on its side wall, thereby expanding the cleaning coverage area and improving the cleaning effect and work efficiency. The sealing sleeve 307 is designed to prevent water from flowing to the other side of the sealing sleeve 307 when it flows into the heating tank, while the connecting wire 306 is covered with a waterproof layer, and the heat preservation circuit is conductive.

[0029] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 4 Specifically, the inlet pipe 301 is also equipped with a baffle plate 315, and the baffle plate 315 is set at an angle.

[0030] An obstruction plate 315 is installed at an angle inside the inlet pipe 301. The obstruction plate 315 is set at an angle, which can gather and guide the water flow, so that more water flows into the heating tank through the water inlet hole 311, ensuring stable operation of fixed-point heating and cleaning. The handheld instrument cleaning device 1 has a timer function to drive the lumen instrument cleaning component 3 to clean the inner wall of the lumen instrument at regular intervals. At the same time, the lumen instrument cleaning component 3 can be disassembled for easy subsequent cleaning, replacement and storage.
