[0001] The invention relates to the technical field of medical device sterilization and drying, in particular to a medical device sterilization and drying device for nursing. Background Art

[0002] Nursing requires a large number of instruments such as scissors and tweezers, which need to be cleaned and disinfected after use. Existing cleaning and disinfection devices generally perform cleaning and disinfection by soaking, stirring, and scrubbing. The method is single, cannot fully perform cleaning and disinfection, and has low efficiency.

[0003] In the prior art, the patent document with publication number CN112058739A discloses a nursing instrument cleaning and disinfecting device, which includes a mounting frame, a fixed cylinder, a mounting plate and a fixed shaft. The fixed cylinder is fixedly mounted on the mounting frame, a flow channel for liquid flow is provided in the cylinder wall of the fixed cylinder, and spray holes connected to the flow channel are evenly opened on the inner wall of the fixed cylinder. The above device has a high degree of automation and improves work efficiency. However, the above device has the following technical problems when used: The existing devices lack a linkage mechanical structure design driven by a single motor and are unable to efficiently integrate multiple functions such as cleaning, disinfection, and drying. The existing cleaning methods are single-function and difficult to completely remove dirt.

[0004] Based on this, the present invention provides a nursing medical instrument disinfection and drying device to solve the problems raised in the above background technology. Summary of the invention

[0005] The present invention aims at the technical problems existing in the prior art and provides a nursing medical instrument disinfection and drying device to solve the problem that the prior device has a single function and is difficult to completely remove dirt.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: a nursing medical device disinfection and drying device comprises a disinfection tank, an ultrasonic cleaning mechanism is arranged in the disinfection tank, a vibration and rotation composite drive mechanism is installed on the upper part of the disinfection tank, a rotary washing frame that can rotate synchronously and vibrate up and down is connected to the vibration and rotation composite drive mechanism, a rotation generating module is installed on the rotary washing frame, a cyclically rotatable cleaning carrier is installed on the rotary generating module, an elastic band is installed equidistantly on the cleaning carrier, a reciprocating shaking drive mechanism is arranged on the rotary washing frame, a reciprocating shaking cradle is installed on the reciprocating shaking drive mechanism, a rocking roller that is connected to the cleaning carrier is rotatably installed on the inner wall of the cradle, a jet rotating brushing mechanism is arranged on the cradle, a pumping mechanism that circulates pump liquid to the jet rotating brushing mechanism is arranged on the rotary washing frame, two rotatable cleaning pressure shafts are rotatably installed on the rotary washing frame and corresponding to the inner side of the cleaning carrier, and a group of cleaning convex plates that fit the cleaning carrier are installed on both of the cleaning pressure shafts.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the ultrasonic cleaning mechanism includes a first ultrasonic cleaning unit fixed to the bottom of the sterilization tank and a second ultrasonic cleaning unit installed on the inner wall of the sterilization tank. A heating jacket is installed on the sterilization tank. A single-chip microcomputer is installed on the end face of the sterilization tank. The bottom end of the sterilization tank is connected to a drain valve.

[0009] The beneficial effect of adopting the above further scheme is that when in use, first inject an appropriate amount of disinfectant into the disinfection tank, place the medical device to be disinfected on the cleaning carrier, fix it with an elastic band, turn on the first ultrasonic cleaning unit and the second ultrasonic cleaning unit, which will generate high-frequency vibrations to form countless tiny bubbles in the disinfectant. These bubbles burst when they come into contact with the surface of the medical device, generating a strong impact force, thereby effectively removing dirt and impurities on the surface of the medical device; At the same time, the heating jacket can heat the disinfectant as needed to improve the cleaning effect. The single-chip microcomputer is used to control the operation of each component, such as setting the time of ultrasonic cleaning, the heating temperature, etc. After the disinfection is completed, the disinfectant containing dirt is discharged through the drain valve; Compared with simple scrubbing, ultrasonic cleaning can penetrate into the gaps and grooves of the instruments, improving the comprehensiveness and thoroughness of cleaning, ensuring the cleanliness of medical instruments before disinfection, laying a good foundation for subsequent disinfection work, and ensuring the disinfection effect; Furthermore, the vibration and rotation composite drive mechanism includes a support frame and a vibrating frame, the support frame is fixedly connected to the disinfection tank, a driving motor is installed on the support frame, a fixed shaft is rotatably installed on the support frame, the output shaft end of the driving motor is connected to the fixed shaft through a first belt, the spin washing frame is rotatably installed on the vibrating frame, the vibrating frame is slidably connected to the support frame, a reset spring limited by the disinfection tank is installed on the bottom surface of the vibrating frame, a movable shaft is fixedly installed on the spin washing frame, a wheel axle is rotatably installed on the support frame, the movable shaft and the wheel axle are both driven by the fixed shaft, an eccentric cam is installed on the wheel axle, an I-shaped wheel is rotatably installed on the vibrating frame, and the eccentric cam is fitted with the I-shaped wheel.

[0010] The beneficial effect of adopting the above further scheme is that when in use, the driving motor is started, and its output shaft drives the fixed shaft to rotate through the first belt. When the fixed shaft rotates, on the one hand, it drives the movable shaft to rotate through the cooperation with the opening groove of the movable shaft, thereby rotating the spin washing frame. On the other hand, the fixed shaft drives the wheel shaft to rotate, and the eccentric cam on the wheel shaft rotates accordingly. During the rotation of the eccentric cam, it fits with the I-shaped wheel on the vibrating frame, pushing the vibrating frame to do up and down reciprocating motion on the support frame. Since the spin washing frame is rotatably installed on the vibrating frame, the spin washing frame will vibrate up and down synchronously. This vibration and rotation composite motion solves the problem of insufficient cleaning of medical devices during the cleaning process. The current single cleaning method makes it difficult to effectively remove some dirt in one go. This mechanism allows the medical device to vibrate up and down while rotating, allowing the disinfectant to more fully contact various parts of the medical device, thereby enhancing the cleaning effect and improving the cleaning efficiency. It can also cause dirt to leave the surface of the medical device faster and be taken away by the disinfectant.

[0011] Furthermore, an open groove with a top opening and slidably connected to the fixed shaft is fixed inside the movable shaft, and the cross-sections of the open groove and the fixed shaft are both regular polygons. A first bevel gear is installed on the wheel axle and the fixed shaft, and the two first bevel gears are meshed with each other.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the open groove inside the movable shaft is slidably connected to the fixed shaft and the cross-sections of the two are regular polygons, which enables the fixed shaft to stably drive the movable shaft to rotate when rotating, and at the same time the movable shaft can slide up and down along the fixed shaft, solving the problem of unstable power transmission when realizing the vibration and rotation composite motion. The connection method may slip or fail to realize axial movement, and this regular polygon connection structure ensures the reliability of power transmission, ensuring that the movable shaft can accurately transmit the rotation and axial movement of the fixed shaft to the rotary washing rack, thereby ensuring the stable and efficient operation of the entire cleaning device and improving the service life and cleaning performance of the equipment.

[0013] Further, the rotation generating module includes a sleeve shaft rotatably mounted on a movable shaft, the sleeve shaft and the movable shaft rotate coaxially and in opposite directions, two heating rollers are rotatably mounted on the spin washing frame, both of the two heating rollers are equipped with electric heating rods, both of the two heating rollers are transmission connected to the cleaning carrier, a synchronous shaft and a pump shaft are rotatably mounted on the spin washing frame, the sleeve shaft is transmission connected to the synchronous shaft through a second belt, a second bevel gear is installed on both the synchronous shaft and the pump shaft, the two second bevel gears are meshed with each other, and a third belt is transmission installed between the pump shaft and one of the heating rollers.

[0014] The beneficial effect of adopting the above further scheme is that when in use, the movable shaft rotates to drive the sleeve shaft to rotate in the opposite direction of the same axis, the sleeve shaft drives the synchronous shaft to rotate through the second belt, the second bevel gear on the synchronous shaft and the pump shaft meshes with each other to rotate the pump shaft, and the pump shaft drives a heating roller to rotate through the third belt, thereby driving the cleaning carrier to rotate cyclically. At the same time, the electric heating rods built into the two heating rollers can heat the cleaning carrier, which plays a role in drying the nursing medical device after cleaning; This module solves the problem that the cleaning carrier cannot circulate automatically and the medical devices are not dried in time after cleaning. The existing method may require manual rotation of the cleaning carrier, which is inefficient and inconvenient to operate. This module realizes the automatic circulation of the cleaning carrier, improves the cleaning efficiency, and the heating function of the heating roller dries the medical devices in time, avoiding secondary contamination caused by long-term moisture of the devices after cleaning, thereby ensuring the cleanliness and hygiene of the medical devices.

[0015] Furthermore, a reversing shaft is rotatably mounted on the vibrating dirt frame, a reversing bevel gear is mounted on the reversing shaft, a second bevel gear is mounted on both the sleeve shaft and the movable shaft, two of the second bevel gears are transmission-connected to the reversing bevel gear, and the two second bevel gears are respectively arranged on both sides of the reversing bevel gear.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that when in use, when the movable shaft rotates, the second bevel gear on the sleeve shaft and the movable shaft realizes coaxial reverse rotation of the sleeve shaft and the movable shaft under the action of the reversing bevel gear on the reversing shaft, which solves the problem of how to realize reverse rotation of the two components under the same power source. In existing designs, realizing reverse rotation often requires multiple power sources or complex transmission structures, which increases equipment cost and failure risk. This reversing shaft and related gear structure utilizes the transmission characteristics of the bevel gear to realize reverse rotation of the sleeve shaft and the movable shaft without adding an additional power source, thereby simplifying the transmission structure, reducing equipment cost, and improving equipment stability and reliability.

[0017] Furthermore, the reciprocating rocking drive mechanism includes a rocking shaft installed on a rocking frame, the rocking shaft is rotatably installed on the spin washing frame, a torsion spring is provided at the rotational connection between the rocking shaft and the spin washing frame, a rocking gear is installed on the rocking shaft, a toothless shaft is rotatably installed on the spin washing frame, a toothless gear is installed on the toothless shaft, a toothed area and a toothless area are respectively provided on the toothed area, the central angle corresponding to the toothed area is 45°, the toothed area is evenly distributed with teeth connected to the rocking gear, and the radius of the toothless gear is the same as the radius of the rocking gear.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that when in use, the toothed shaft drives the toothed gear to rotate, and when the toothed surface of the toothed gear meshes with the rocking gear, it drives the rocking shaft to rotate, and the rocking frame rocks accordingly. The torsion spring stores and releases elastic potential energy during the rocking process of the rocking frame, so that the rocking frame can rock back and forth. When the rocking frame rocks, it drives the rocking roller to apply forces in different directions to the cleaning carrier, causing it to shake. This solves the problem that the cleaning carrier is fixed in position during the cleaning process, resulting in insufficient cleaning of some areas. In the existing cleaning method, the cleaning carrier is often fixed and some parts of the instrument are difficult to be fully cleaned. The reciprocating rocking drive mechanism causes the cleaning carrier to shake, which further enhances the cleaning effect and allows all parts of the medical device to better contact with the disinfectant and cleaning components, thereby improving the uniformity and thoroughness of the cleaning.

[0019] Furthermore, the jet rotating brushing mechanism includes a fourth belt which is transmission-connected to the rocking shaft, an inner spray shaft is rotatably installed on the rocking frame and corresponds to the position inside the cleaning carrier, a plurality of groups of inner spray holes are provided on the inner spray shaft, a plurality of groups of cleaning stirring rods are installed on the inner spray shaft, two outer brush shafts are rotatably installed on the rocking frame and correspond to the position outside the cleaning carrier, a plurality of groups of outer spray holes are provided on the two outer brush shafts, a plurality of groups of rubber brush strips are installed on the two outer brush shafts, and the inner spray shaft, the outer brush shaft and the cleaning pressure shaft are all transmission-connected to the fourth belt.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that when in use, the rotation of the rocker shaft drives the inner spray shaft, the outer brush shaft and the cleaning pressure shaft to rotate through the fourth belt, and the inner spray hole on the inner spray shaft and the outer spray hole on the outer brush shaft spray disinfectant under the action of the pumping mechanism to rinse the medical devices on the cleaning carrier. At the same time, the cleaning stirring rod on the inner spray shaft stirs and cleans the inside of the device, and the rubber brush strip on the outer brush shaft brushes the outside of the device. The cleaning convex plate on the cleaning pressure shaft fits with the cleaning carrier to assist in cleaning. This solves the problem that medical devices cannot be rinsed, brushed and stirred at the same time. The cleaning method has a single function and it is difficult to remove dirt completely at one time. The mechanism improves the cleaning effect by combining multiple cleaning methods, and can more thoroughly remove dirt on the surface and inside of the medical device, ensuring the cleanliness of the medical device and reducing the risk of cross infection.

[0021] Furthermore, the liquid pumping mechanism includes a high-pressure pump barrel installed on the rotary washing frame, a group of high-pressure pump blades are installed on the pump shaft and at a position corresponding to the inner side of the high-pressure pump barrel, the suction port of the high-pressure pump barrel is connected to a suction tube, a diverter pipe is installed on the side of the cradle, the liquid outlet port of the high-pressure pump barrel is connected to the diverter pipe through a hose, and the inner spray hole and the outer spray hole are both connected to the diverter pipe.

[0022] The beneficial effect of adopting the above further scheme is that when in use, the pump shaft rotates to drive the high-pressure pump blade to rotate in the high-pressure pump barrel, and the disinfectant in the disinfection tank is sucked through the liquid pipette. After the disinfectant is pressurized by the high-pressure pump blade, it enters the shunt pipe through the liquid outlet port and the hose of the high-pressure pump barrel, and then flows from the shunt pipe into the inner spray hole and the outer spray hole respectively, so as to realize the spray cleaning of the medical device on the cleaning carrier; This solves the problem of disinfectant not being effectively delivered to the cleaning site. There may be uneven spraying of disinfectant or insufficient pressure. The pump mechanism ensures that the disinfectant can be sprayed onto the medical device stably and at high pressure, enhancing the cleaning effect, ensuring the comprehensiveness and efficiency of cleaning, and making the cleaning process more reliable.

[0023] Furthermore, the cleaning carrier and the elastic band are both made of silicone material, and the outer surface of the cleaning carrier and the inner wall of the elastic band are fixedly provided with friction patterns.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that when in use, the cleaning carrier tape and elastic strap made of silicone material have good flexibility and elasticity, can better fit the shape of the medical device, and are not easy to cause damage to the medical device when fixing it. At the same time, the silicone material has good corrosion resistance and is not easily corroded by disinfectants, which extends the service life of the cleaning carrier tape and the elastic strap. This solves the problem that the material may damage the medical device and have a short service life. The cleaning carrier tape and the fixing strap material may scratch the surface of the medical device, affecting the accuracy and service life of the device, and are easily corroded by disinfectants. The use of silicone material not only protects the medical device, but also reduces the maintenance cost of the equipment and improves the overall performance of the equipment.

[0025] The beneficial effects of the present invention are: 1. The key innovation of the present invention is to use a single motor to drive a complex and efficient cleaning, disinfection and drying system. The driving motor drives the fixed shaft to rotate, and then drives the movable shaft to rotate the rotary washing frame. At the same time, the eccentric cam on the wheel shaft pushes the vibrating dirt frame to make the rotary washing frame vibrate up and down. This vibration and rotation composite motion allows the disinfectant to fully cover all parts of the medical device, greatly enhancing the cleaning effect. The first and second ultrasonic cleaning units of the ultrasonic cleaning mechanism generate high-frequency vibrations, which cause the tiny bubbles in the high-temperature disinfectant to burst and generate a strong impact force, penetrate into the gaps and grooves of the medical device to remove dirt, and lay a good foundation for disinfection work. Driven by the rocker shaft, the jet rotary brushing mechanism rotates the inner spray shaft, the outer brush shaft and the cleaning pressure shaft synchronously, and performs flushing, brushing and stirring cleaning respectively, and cooperates with high-temperature ultrasonic cleaning to comprehensively remove dirt and miscellaneous bacteria on the surface of the instrument, ensuring the cleanliness and sterility of the instrument after disinfection, effectively reducing the risk of cross infection, and achieving efficient disinfection.

[0026] 2. The single motor drive in the present invention not only realizes the automatic circulation rotation of the cleaning carrier, but also achieves the rapid drying of the medical device after cleaning. The rotation of the movable shaft drives the sleeve shaft to rotate in the opposite direction. Through a series of belts and gears, the cleaning carrier continues to circulate, avoiding the cumbersome and inefficient manual operation. After cleaning, the built-in electric heating rod of the heating roller connected to the transmission system starts to work, heating the cleaning carrier, and the heat is transferred to the medical device, prompting the surface water to evaporate quickly, realizing the drying function. The cyclic rotation of the cleaning carrier ensures that the medical device is heated evenly, improves the drying efficiency and uniformity, effectively avoids the secondary contamination of the device after cleaning due to long-term moisture, and ensures the cleanliness and hygiene of the medical device.

[0027] 3. In the process of realizing the disinfection and drying function, the present invention optimizes the structure with the help of a single motor drive, and the movable shaft and the fixed shaft are connected by a regular polygon to ensure stable and reliable power transmission and maintain the stable operation of the vibration and rotation compound motion. The reversing shaft and the related bevel gear structure realize the reverse rotation of the sleeve shaft and the movable shaft under the power source of a single motor, simplifying the transmission structure, reducing equipment costs and failure risks. In addition, the cleaning carrier and elastic strap made of silicone material can not only firmly fix the medical device, but also avoid damage to the device due to its good flexibility and elasticity, and have strong corrosion resistance, which prolongs the service life, further reduces the equipment maintenance cost, and improves the overall performance of the equipment.

DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The present invention provides the following preferred embodiments like Figure 1-Figure 10 As shown, a sterilizing and drying device for medical instruments for nursing use comprises a sterilizing tank 1, in which an ultrasonic cleaning mechanism is arranged; The ultrasonic cleaning mechanism includes a first ultrasonic cleaning unit 9 fixed to the bottom of the sterilization tank 1 and a second ultrasonic cleaning unit 10 installed on the inner wall of the sterilization tank 1. A heating jacket 11 is installed on the sterilization tank 1. A single-chip microcomputer is installed on the end face of the sterilization tank 1. The bottom end of the sterilization tank 1 is connected to a drain valve.

[0032] When in use, first inject an appropriate amount of disinfectant into the disinfection tank 1, place the medical device to be disinfected on the cleaning carrier 3, fix it with the elastic band 4, turn on the first ultrasonic cleaning unit 9 and the second ultrasonic cleaning unit 10, which will generate high-frequency vibrations to form countless tiny bubbles in the disinfectant. These bubbles burst when they come into contact with the surface of the medical device, generating a strong impact force, thereby effectively removing dirt and impurities on the surface of the medical device; At the same time, the heating jacket 11 can heat the disinfectant as needed to improve the cleaning effect. The single-chip microcomputer is used to control the operation of each component, such as setting the ultrasonic cleaning time, heating temperature, etc. After the disinfection is completed, the disinfectant containing dirt is discharged through the drain valve; This mechanism solves the problem that a single cleaning method cannot completely clean the dirt on the surface of medical devices. Compared with simple brushing, ultrasonic cleaning can penetrate into the gaps and grooves of the equipment, improving the comprehensiveness and thoroughness of cleaning, ensuring the cleanliness of medical devices before disinfection, laying a good foundation for subsequent disinfection work, and ensuring the disinfection effect; A vibration and rotation composite drive mechanism is installed on the upper part of the disinfection tank 1, and a rotary washing frame 2 that can rotate synchronously and vibrate up and down is connected to the vibration and rotation composite drive mechanism, and a rotary generation module is installed on the rotary washing frame 2, and a cleaning carrier belt 3 that can rotate cyclically is installed on the rotary generation module; The vibration and rotation composite driving mechanism includes a support frame 12 and a vibrating frame 13. The support frame 12 is fixedly connected to the disinfection tank 1. A driving motor 14 is installed on the support frame 12. A fixed shaft 15 is rotatably installed on the support frame 12. The output shaft end of the driving motor 14 is transmission-connected to the fixed shaft 15 through a first belt. The spin-washing frame 2 is rotatably installed on the vibrating frame 13. The vibrating frame 13 is slidably connected to the support frame 12. A reset spring 16 limited by the disinfection tank 1 is installed on the bottom surface of the vibrating frame 13. A movable shaft 17 is fixedly installed on the spin-washing frame 2. A wheel shaft 18 is rotatably installed on the support frame 12. Both the movable shaft 17 and the wheel shaft 18 are driven by the fixed shaft 15. An eccentric cam 19 is installed on the wheel shaft 18. An I-shaped wheel 20 is rotatably installed on the vibrating frame 13. The eccentric cam 19 fits well with the I-shaped wheel 20.

[0033] When in use, the driving motor 14 is started, and its output shaft drives the fixed shaft 15 to rotate through the first belt. When the fixed shaft 15 rotates, on the one hand, it drives the movable shaft 17 to rotate by cooperating with the open groove of the movable shaft 17, thereby rotating the spin washing frame 2. On the other hand, the fixed shaft 15 drives the wheel shaft 18 to rotate, and the eccentric cam 19 on the wheel shaft 18 rotates accordingly. During the rotation of the eccentric cam 19, it fits with the I-shaped wheel 20 on the vibrating frame 13, pushing the vibrating frame 13 to do up and down reciprocating motion on the support frame 12. Since the spin washing frame 2 is rotatably installed on the vibrating frame 13, the spin washing frame 2 will vibrate up and down synchronously. This vibration and rotation composite motion solves the problem of insufficient cleaning of medical equipment during the cleaning process. A single cleaning method makes it difficult to remove some dirt in one go, but this mechanism allows the medical device to vibrate up and down while rotating, allowing the disinfectant to more fully contact all parts of the medical device, enhancing the cleaning effect, improving the cleaning efficiency, and also allowing the dirt to leave the surface of the medical device faster and be taken away by the disinfectant.

[0034] An open groove with an opening at the top and slidingly connected to the fixed shaft 15 is fixed inside the movable shaft 17. The cross-sections of the open groove and the fixed shaft 15 are both regular polygons. A first bevel gear is installed on the axle 18 and the fixed shaft 15, and the two first bevel gears are meshed with each other.

[0035] The open groove inside the movable shaft 17 is slidably connected to the fixed shaft 15 and the cross-sections of the two are regular polygons, which enables the fixed shaft 15 to stably drive the movable shaft 17 to rotate when rotating, and the movable shaft 17 can slide up and down along the fixed shaft 15, solving the problem of unstable power transmission when realizing the vibration and rotation composite motion. The existing connection method may slip or fail to realize axial motion, and this regular polygon connection structure ensures the reliability of power transmission, ensuring that the movable shaft 17 can accurately transmit the rotation and axial motion of the fixed shaft 15 to the spin washing frame 2, thereby ensuring the stable and efficient operation of the entire cleaning device and improving the service life and cleaning performance of the equipment.

[0036] The rotation generating module includes a sleeve shaft 21 rotatably sleeved on the movable shaft 17, the sleeve shaft 21 and the movable shaft 17 rotate coaxially and in the opposite direction, two heating rollers 22 are rotatably installed on the spin washing frame 2, both of which have built-in electric heating rods, and both of which are transmission connected to the cleaning carrier 3, a synchronous shaft 23 and a pump shaft 24 are rotatably installed on the spin washing frame 2, the sleeve shaft 21 is transmission connected to the synchronous shaft 23 through a second belt, a second bevel gear is installed on the synchronous shaft 23 and the pump shaft 24, the two second bevel gears are meshed with each other, and a third belt is transmission installed between the pump shaft 24 and a heating roller 22.

[0037] When in use, the movable shaft 17 rotates to drive the sleeve shaft 21 to rotate in the coaxial opposite direction through the reversing shaft 25 and the reversing bevel gear. The sleeve shaft 21 drives the synchronous shaft 23 to rotate through the second belt. The second bevel gears on the synchronous shaft 23 and the pump shaft 24 mesh with each other to rotate the pump shaft 24. The pump shaft 24 drives a heating roller 22 to rotate through the third belt, thereby driving the cleaning carrier 3 to circulate. At the same time, the electric heating rods built into the two heating rollers 22 can heat the cleaning carrier 3, which plays a role in drying the nursing medical equipment after cleaning. This module solves the problem that the cleaning carrier 3 cannot circulate automatically and the medical equipment is not dried in time after cleaning. The cleaning carrier may need to be rotated manually, which is inefficient and inconvenient to operate. This module realizes the automatic circulation of the cleaning carrier 3, improves the cleaning efficiency, and the heating function of the heating roller 22 dries the medical equipment in time, avoiding secondary contamination caused by the equipment being wet for a long time after cleaning, thereby ensuring the cleanliness of the medical equipment.

[0038] A reversing shaft 25 is rotatably mounted on the dirt vibration frame 13, a reversing bevel gear is mounted on the reversing shaft 25, a second bevel gear is mounted on both the sleeve shaft 21 and the movable shaft 17, the two second bevel gears are both transmission-connected with the reversing bevel gear, and the two second bevel gears are respectively arranged on both sides of the reversing bevel gear.

[0039] When in use, when the movable shaft 17 rotates, the sleeve shaft 21 and the second bevel gear on the movable shaft 17 realize the coaxial opposite rotation of the sleeve shaft 21 and the movable shaft 17 under the action of the reversing bevel gear on the reversing shaft 25, which solves the problem of how to realize the reverse rotation of the two components under the same power source. Realizing reverse rotation often requires multiple power sources or complex transmission structures, which increases equipment cost and failure risk. This reversing shaft and related gear structure utilizes the transmission characteristics of the bevel gear to realize the reverse rotation of the sleeve shaft 21 and the movable shaft 17 without adding an additional power source, thereby simplifying the transmission structure, reducing equipment cost, and improving equipment stability and reliability.

[0040] Elastic straps 4 are equidistantly installed on the cleaning carrier belt 3; The cleaning carrier tape 3 and the elastic band 4 are both made of silicone material, and the outer surface of the cleaning carrier tape 3 and the inner wall of the elastic band 4 are fixedly provided with friction patterns.

[0041] When in use, the cleaning carrier 3 and the elastic band 4 made of silicone material have good flexibility and elasticity, can better fit the shape of the medical device, and are not easy to damage the medical device when fixing it. At the same time, the silicone material has good corrosion resistance and is not easily corroded by disinfectants, which prolongs the service life of the cleaning carrier 3 and the elastic band 4. This solves the problem that some materials may damage medical devices and have a short service life. Some cleaning carriers and fixing bands may scratch the surface of medical devices, affecting the accuracy and service life of the devices, and are easily corroded by disinfectants. The use of silicone material not only protects the medical devices, but also reduces the maintenance cost of the equipment and improves the overall performance of the equipment. The rotary washing frame 2 is provided with a reciprocating rocking driving mechanism, and a reciprocating rocking cradle 5 is installed on the reciprocating rocking driving mechanism; The reciprocating rocking drive mechanism includes a rocking shaft 26 installed on the rocking frame 5, and the rocking shaft 26 is rotatably installed on the rotary washing frame 2. A torsion spring 27 is provided at the rotation connection between the rocking shaft 26 and the rotary washing frame 2. A rocking gear 28 is installed on the rocking shaft 26. A toothed shaft 29 is rotatably installed on the rotary washing frame 2. A toothed gear 30 is installed on the toothed shaft 29. The toothed gear 30 is respectively provided with a toothed area and a toothless area. The central angle corresponding to the toothed area is 45°. The toothed area is evenly distributed with teeth that are transmission-connected to the rocking gear 28. The radius of the toothed gear 30 is the same as the radius of the rocking gear 28.

[0042] When in use, the toothed shaft 29 drives the toothed gear 30 to rotate. When the toothed surface of the toothed gear 30 meshes with the rocking gear 28, it drives the rocking shaft 26 to rotate, and the cradle 5 is rocked accordingly. The torsion spring 27 stores and releases elastic potential energy during the rocking process of the cradle 5, so that the cradle 5 can rock back and forth. When the cradle 5 rocks, it drives the rocking roller 6 to apply forces in different directions to the cleaning carrier 3, causing it to rock. This solves the problem that the cleaning carrier 3 is fixed in position during the cleaning process, resulting in insufficient cleaning of some areas. In some cleaning methods, the cleaning carrier is often fixed and it is difficult to fully clean some parts of the instrument. The reciprocating rocking drive mechanism causes the cleaning carrier 3 to rock, which further enhances the cleaning effect, allowing all parts of the medical instrument to better contact with the disinfectant and cleaning components, thereby improving the uniformity and thoroughness of the cleaning. A rocking roller 6 which is transmission-connected to the cleaning carrier 3 is rotatably mounted on the inner wall of the rocking frame 5, a jet rotary brushing mechanism is provided on the rocking frame 5, a pumping mechanism for circulating pump liquid to the jet rotary brushing mechanism is provided on the rotary washing frame 2, two rotatable cleaning pressure shafts 7 are rotatably mounted on the rotary washing frame 2 and corresponding to the position on the inner side of the cleaning carrier 3, and a group of cleaning convex plates 8 which are in contact with the cleaning carrier 3 are installed on the two cleaning pressure shafts 7.

[0043] The jet rotary brushing mechanism includes a fourth belt which is transmission-connected to the rocking shaft 26; an inner spray shaft 31 is rotationally mounted on the rocking frame 5 and corresponds to the position on the inner side of the cleaning carrier 3; a plurality of inner spray holes 32 are provided on the inner spray shaft 31; a plurality of cleaning stirring rods 33 are installed on the inner spray shaft 31; two outer brush shafts 34 are rotationally mounted on the rocking frame 5 and correspond to the position on the outer side of the cleaning carrier 3; a plurality of outer spray holes 35 are provided on the two outer brush shafts 34; a plurality of rubber brush strips 36 are installed on the two outer brush shafts 34; the inner spray shaft 31, the outer brush shaft 34 and the cleaning pressure shaft 7 are all transmission-connected to the fourth belt.

[0044] During use, the rocking shaft 26 rotates through the fourth belt to drive the inner spray shaft 31, the outer brush shaft 34 and the cleaning pressure shaft 7 to rotate, and the inner spray hole 32 on the inner spray shaft 31 and the outer spray hole 35 on the outer brush shaft 34 spray disinfectant under the action of the pumping mechanism to rinse the medical equipment on the cleaning carrier 3. At the same time, the cleaning stirring rod 33 on the inner spray shaft 31 stirs and cleans the inside of the equipment, and the rubber brush strip 36 on the outer brush shaft 34 brushes the outside of the equipment. The cleaning convex plate 8 on the cleaning pressure shaft 7 is in contact with the cleaning carrier 3 to assist in cleaning. This solves the problem that medical equipment cannot be rinsed, brushed and stirred at the same time. Some cleaning methods have a single function and it is difficult to completely remove dirt. The mechanism improves the cleaning effect by combining multiple cleaning methods, and can more thoroughly remove dirt on the surface and inside of medical equipment, thereby ensuring the cleanliness of medical equipment and reducing the risk of cross infection.

[0045] The liquid pumping mechanism includes a high-pressure pump barrel 37 installed on the rotary washing frame 2, a group of high-pressure pump blades 38 are installed on the pump shaft 24 and at a position corresponding to the inner side of the high-pressure pump barrel 37, the suction port of the high-pressure pump barrel 37 is connected to a suction pipe 39, a shunt pipe 40 is installed on the side of the cradle 5, the liquid outlet port of the high-pressure pump barrel 37 is connected to the shunt pipe 40 through a hose, and the inner spray hole 32 and the outer spray hole 35 are both connected to the shunt pipe 40.

[0046] When in use, the pump shaft 24 rotates to drive the high-pressure pump blade 38 to rotate in the high-pressure pump barrel 37, and the disinfectant in the disinfection tank 1 is sucked through the suction tube 39. After the disinfectant is pressurized by the high-pressure pump blade 38, it enters the shunt pipe 40 through the liquid outlet port and the hose of the high-pressure pump barrel 37, and then flows from the shunt pipe 40 into the inner spray hole 32 and the outer spray hole 35 respectively, so as to realize the spray cleaning of the medical devices on the cleaning carrier 3; This solves the problem that disinfectant cannot be effectively delivered to the cleaning area. Some methods may result in uneven disinfectant spraying or insufficient pressure. The pump mechanism ensures that the disinfectant can be sprayed onto the medical device stably and at high pressure, enhancing the cleaning effect, ensuring the comprehensiveness and efficiency of cleaning, and making the cleaning process more reliable.

[0047] The specific method of use of the present invention is as follows: When using the present nursing medical device disinfection and drying device, first inject an appropriate amount of disinfectant into the disinfection tank 1, place the nursing medical device to be disinfected on the cleaning carrier 3 and fix it with the elastic band 4, turn on the device, start the driving motor 14, and its output shaft drives the fixed shaft 15 to rotate through the first belt. The fixed shaft 15 drives the movable shaft 17 to rotate on the one hand, so that the rotary washing frame 2 rotates, and drives the wheel shaft 18 to rotate on the other hand. The eccentric cam 19 on the wheel shaft 18 drives the vibrating frame 13 to do up and down reciprocating motion on the support frame 12, thereby making the rotary washing frame 2 vibrate up and down synchronously, realizing the vibration and rotation composite motion, so that the disinfectant can more fully contact the medical device and enhance the cleaning effect; The movable shaft 17 rotates to drive the sleeve shaft 21 to rotate in the opposite direction of the same axis. The sleeve shaft 21 drives the synchronous shaft 23 to rotate through the second belt. The synchronous shaft 23 and the second bevel gear on the pump shaft 24 mesh with each other to rotate the pump shaft 24. The pump shaft 24 drives a heating roller 22 to rotate through the third belt, thereby driving the cleaning carrier belt 3 to rotate in a circular manner. The toothless shaft 29 drives the toothless gear 30 to rotate. When the toothless surface of the toothless gear 30 meshes with the rocking gear 28, the rocking shaft 26 is driven to rotate, and the cradle 5 is rocked accordingly. The torsion spring 27 stores and releases elastic potential energy to make the cradle 5 rock back and forth, driving the rocking roller 6 to apply forces in different directions to the cleaning carrier 3 to make it rock, thereby enhancing the cleaning effect. The pump shaft 24 rotates to drive the high-pressure pump blade 38 to rotate in the high-pressure pump barrel 37, and the disinfectant in the disinfection tank 1 is sucked through the suction tube 39, and after being pressurized, it enters the shunt pipe 40 through the hose, and then flows into the inner spray hole 32 and the outer spray hole 35 from the shunt pipe 40. The rocker shaft 26 rotates to drive the inner spray shaft 31, the outer brush shaft 34 and the cleaning pressure shaft 7 to rotate through the fourth belt. The inner spray hole 32 of the inner spray shaft 31 and the outer spray hole 35 of the outer brush shaft 34 spray disinfectant to rinse the medical device. The cleaning stirring rod 33 on the inner spray shaft 31 stirs the inside of the device, and the rubber brush strip 36 on the outer brush shaft 34 brushes the outside of the device. The cleaning convex plate 8 on the cleaning pressure shaft 7 assists in cleaning; In addition, the first ultrasonic cleaning unit 9 and the second ultrasonic cleaning unit 10 generate high-frequency vibrations to form tiny bubbles in the disinfectant, and the bubbles burst to generate impact force to remove dirt and impurities. The heating jacket 11 can heat the disinfectant to improve the cleaning effect. The single-chip microcomputer controls the operation of each component. After the disinfection is completed, the disinfectant containing dirt is discharged through the drain valve; After the disinfectant is discharged, the electric heating rods built into the two heating rollers 22 continue to work to heat the cleaning carrier 3. Since the medical device is placed on the cleaning carrier 3, the heat of the cleaning carrier 3 will be transferred to the medical device, causing the moisture on the surface of the medical device to evaporate quickly, thereby realizing the drying process. At the same time, the circulating rotation of the cleaning carrier 3 can ensure that all parts of the medical device can be evenly heated, thereby improving the uniformity and efficiency of drying and avoiding secondary contamination caused by the long-term moisture of the device after cleaning.
