Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a fully automatic ozone water disinfection device for medical devices. Background Technology

[0002] Disinfection of medical devices is a crucial step in ensuring medical safety. Its core is to kill or remove pathogenic microorganisms, such as bacteria, viruses, and fungi, attached to the surface and interior of medical devices through physical, chemical, or biological methods to prevent cross-infection. Depending on the risk level of the medical device, high-risk devices such as surgical instruments, medium-risk devices such as gastroscopes, and low-risk devices such as blood pressure cuffs require different disinfection methods. High-risk devices need to reach sterilization levels, which are commonly achieved through high-pressure steam sterilization, ethylene oxide sterilization, and ozone water disinfection. Medium-risk devices need to reach high-level disinfection, which can be achieved through immersion in chlorine-containing disinfectants or ultraviolet irradiation. Low-risk devices are disinfected at medium to low levels, such as by wiping with alcohol.

[0003] In the current field of technology, medical device disinfection equipment relies on static soaking. Complex structures such as joints and teeth of medical devices are prone to forming disinfection dead corners, making it difficult for ozone water to fully penetrate, resulting in a high rate of microbial residue. In particular, the problem of incomplete disinfection is prominent in hidden parts such as the biting surface of surgical forceps and the tips of tweezers. Furthermore, a lot of manual intervention is required from the insertion and pretreatment of instruments to their removal, which is not only inefficient but also increases the risk of operators coming into contact with contaminants. At the same time, the instability of manual operation also affects the overall disinfection quality. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. After the first robotic arm picks up the surgical instruments from the tray and places them at the corresponding positions on the upper surface of the mounting base plate, the third motors on both sides drive the rotating plates at the corresponding positions to rotate the actuating rods, moving the actuating rods to the corresponding positions above the surgical instrument rings. The second motor, in cooperation with the first lead screw assembly, drives the U-shaped frame to descend to the designated height position, and inserts the two actuating rods on the left and right sides in front of the U-shaped frame into the surgical instrument rings. The third motors on both sides drive the rotating plates at the corresponding positions to rotate the actuating rods outward, so that the cutting edge of the surgical instrument is fully opened. The double-ended motor drives the drive gears on both sides to rotate synchronously, and under the action of the drive gears, the drive gears move backward along the rack. The double-ended motor moves backward into the inner cavity of the outer shell. The second motor drives the lead screw in the first lead screw assembly to rotate in the opposite direction, so that the U-shaped frame moves upward and resets, and the actuating rods on both sides disengage from the surgical instrument rings.

[0014] 2. The first motor drives the bottom shaft, causing the lower sprockets in the left and right sprocket assemblies to rotate synchronously. The chain in the sprocket assembly drives the first roller frame to move upward, causing the bracket to lift the tank basket from inside the ozone water disinfection tank. The second robotic arm picks up the surgical instruments from the mounting plate and places them inside the tank basket. The first motor drives the bottom shaft, causing the lower sprockets in the left and right sprocket assemblies to rotate in the opposite direction. The first roller frame moves downward along the inner side of the first guide rail, causing the bracket to place the tank basket downward on the surface of the second roller frame. The ozone water generator pours the ozone water it produces into the ozone water disinfection tank, completely immersing the surgical instruments inside the tank basket. The ozone water disinfection tank disinfects the surgical instruments inside with ozone water. The first electric telescopic rod intermittently extends and retracts, driving the second roller. The frame moves back and forth along the inner side of the second guide rail, and the second roller frame drives the trough basket to vibrate back and forth to disinfect the surgical instruments inside the trough basket. The moving part moves the outer shell of the trough to the same height position outside the trough basket. The third electric telescopic rods on the left and right sides shorten and drive one end of the connecting rod to move outward, and drive the fixed frame to rotate axially at the other end of the connecting rod, thereby making the fixed frame rotate to a horizontal state. The fifth motors on both sides drive the screw screw in the second screw assembly at the corresponding position to rotate, so that the screw nut in the second screw assembly on both sides drives the moving seat at the corresponding position. The moving seats on both sides move inward under the limiting action of the third limiting component at the corresponding position, and drive the left and right fixed frames to insert into the handle of the trough basket. With the cooperation of the moving part, the trough basket is moved out of the inner cavity of the outer shell.

[0015] This achieves fully automated operation, reduces human contact with contaminants, significantly lowers the risk of infection for operators, greatly improves safety, and enhances the rinsing effect of ozone water on the complex structure of instruments. Combined with pretreatment to open the instrument blades, it significantly improves the thoroughness and efficiency of disinfection. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-7 This invention provides a technical solution: a fully automatic ozone water disinfection device for medical devices, comprising: a disinfection mechanism 1, a transport mechanism 4, a controller 5, and an ozone water generator 6; the disinfection mechanism 1 realizes a series of processes including receiving, pre-processing, and disinfecting medical surgical instruments with ozone water; the transport mechanism 4 is located at the rear of the disinfection mechanism 1, and removes the medical instruments that have been disinfected by the disinfection mechanism 1 from the inside for subsequent processing or storage; the controller 5 is located on the outer left side of the disinfection mechanism 1; the ozone water generator 6 is located on the outer right side of the disinfection mechanism 1.

[0026] As a preferred option, further, such as Figure 2As shown, the disinfection mechanism 1 includes: a housing 11, a disinfection component 2, a mounting tank 12, an instrument transfer component 3, a first robotic arm 13, a guide frame 14, and a second robotic arm 15. The housing 11 is disposed inside the controller 5 and the ozone water generator 6 along the front-back direction. The disinfection component 2 is disposed on the rear side of the inner cavity of the housing 11. The mounting tank 12 is opened on the front side of the top of the housing 11 along the front-back direction. The instrument transfer component 3 is disposed in the inner cavity of the mounting tank 12. The first robotic arm 13 is mounted on the top of the housing 11 and located in front of the mounting tank 12, and the first robotic arm 13 is electrically connected to the controller 5. The guide frame 14 is mounted on the top front side of the outer surface of the housing 11. The second robotic arm 15 is mounted in the inner cavity of the housing 11 and located in front of the disinfection component 2, and the second robotic arm 15 is electrically connected to the controller 5.

[0027] As a preferred option, further, such as Figure 3As shown, the disinfection component 2 includes: an ozone water disinfection tank 21, a first guide rail frame 22, a first roller frame 23, a rotating shaft 24, a first motor 25, a sprocket assembly 26, a bracket 27, a tank basket 28, a second guide rail frame 29, a second roller frame 210, and a first electric telescopic rod 211. The ozone water disinfection tank 21 is embedded inside the outer shell 11 along the front-to-back direction and is located on the rear side of the mounting tank 12. The ozone water disinfection tank 21 is electrically connected to the controller 5. The ozone water disinfection tank 21 provides space for ozone water immersion disinfection of medical devices and has a built-in liquid level sensor and temperature regulation module. The liquid level sensor monitors the ozone water volume in the tank in real time to ensure that the liquid level always meets the immersion requirements during the disinfection process. The temperature regulation module adjusts the liquid level according to the required temperature. According to the disinfection standards of different instruments, the ozone water temperature is precisely controlled by the controller 5. A drain valve is installed at the bottom of the ozone water disinfection tank 21 to automatically discharge waste liquid after disinfection, preparing for the next round of disinfection. The first guide rail frame 22 is fixedly installed at the rear top of the ozone water disinfection tank 21 in the vertical direction, forming a stable guide rail structure. Two grooves are symmetrically arranged on its inner side, precisely cooperating with the rollers on both sides of the first roller frame 23, providing rigid constraint for the lifting and lowering movement of the first roller frame 23, ensuring that it does not shift or shake when bearing the weight of the tank basket 28 and the instruments. The first roller frame 23 is installed inside the ozone water disinfection tank 21, and has rollers installed on both sides. Wear-resistant rollers are embedded in the grooves of the first guide rail frame 22, converting sliding friction into rolling friction, reducing resistance during lifting and lowering, and enabling the first roller frame 23 to move flexibly and efficiently up and down along the first guide rail frame 22 under the drive of the sprocket assembly 26. Two rotating shafts 24 are connected to the upper and lower ends of the inner side of the first guide rail frame 22 via bearings in the left and right directions, respectively. A first motor 25 is installed on the lower right side of the first guide rail frame 22, with its rotating end extending into the inner side of the first guide rail frame 22 and connected to the right end of the axis of the bottom rotating shaft 24. The first motor 25 is electrically connected to the controller 5 and is a servo motor, operating under the commands of the controller 5. When rotating forward, the first roller frame 23 is driven to rise by the sprocket assembly 26 via the rotating shaft 24, and to fall by the first roller frame 23 in reverse. The first motor 25 has a built-in encoder that can provide real-time feedback of the rotation angle to the controller 5, thereby achieving precise control of the lifting height. There are two sprocket assemblies 26. The sprockets in the two sprocket assemblies 26 are keyed to the left and right sides of the outside of the upper and lower rotating shafts 24, respectively. The upper and lower ends of the chains in the two sprocket assemblies 26 are fixedly connected to the upper and lower ends of the first roller frame 23, respectively. When the first motor 25 drives the bottom rotating shaft 24 to rotate, the rotational motion can be converted into the linear lifting motion of the first roller frame 23 through the meshing transmission of the sprockets and chains in the sprocket assembly 26.The bracket 27 is installed on the front side of the first roller frame 23. The bottom end of the bracket 27 extends into the inner cavity of the ozone water disinfection tank 21. The bracket 27 adopts an N-shaped stainless steel frame structure, and the front end is designed with a slot that fits the bottom of the tank basket 28. When the tank basket 28 is placed on it, the slot can limit its lateral movement to prevent the tank basket 28 from slipping during lifting. The tank basket 28 is detachably installed on the surface of the bracket 27. The surface of the tank basket 28 is covered with permeable holes to ensure that the ozone water can fully penetrate into every corner of the basket and make full contact with the equipment. It can also achieve water permeability during lifting. The ozone water disinfection tank 21 features a rapid drainage system. Handles are located on the top left and right sides of the tank basket 28 for easy handling. The handles have anti-slip textures on the inside, allowing for stable gripping in conjunction with the clamping components of the handling mechanism 4. Two second guide rails 29 are positioned on the left and right sides of the bottom center of the inner cavity of the ozone water disinfection tank 21, respectively, and are located inside the left and right brackets 27. These second guide rails 29 cooperate with the rollers at the bottom of the second roller frame 210, providing precise guidance for the reciprocating motion of the second roller frame 210, ensuring that it moves in a straight line when vibrating the tank basket 28. To prevent displacement and collision of instruments with the inner wall of the ozone water disinfection tank 28, the second roller frame 210 is installed on the inner side of the two second guide rail frames 29 on the left and right. The top of the second roller frame 210 is designed with a positioning protrusion that matches the bottom of the tank 28, which can stably limit the tank 28 on it and prevent it from sliding during vibration. High-strength rollers are installed on the left and right sides of the second roller frame 210, and the rollers are embedded in the guide grooves of the second guide rail frame 29. The first electric telescopic rod 211 is installed on the rear side of the outer surface of the ozone water disinfection tank 21, and the telescopic end of the first electric telescopic rod 211 extends into the ozone water. The inner cavity of the disinfection tank 21 is fixedly connected to the rear side of the second roller frame 210. The first electric telescopic rod 211 is electrically connected to the controller 5. Under the control of the controller 5, the first electric telescopic rod 211 drives the second roller frame 210 to reciprocate along the second guide rail frame 29 through its intermittent extension and retraction. This causes the tank basket 28 and the internal instruments to vibrate in the ozone water, breaking the water film tension on the surface of the instruments and allowing the ozone water to penetrate more fully into the joints, teeth, and other hard-to-clean areas of the instruments. At the same time, it accelerates the reaction between ozone molecules and pollutants, significantly improving the disinfection effect.

The first tracks 31 provide guidance for the front-back sliding of the third roller frame 33, limiting its lateral displacement and ensuring the stability of the transfer process; there are two racks 32, which are respectively installed along the front-back direction. The third roller frame 33 is installed on the upper left and right sides of the inner wall of the mounting groove 12; it is installed on the outside of the first track 31 and rack 32 on the left and right sides in the left and right direction. Four sets of high-precision bearing rollers are installed at the upper and lower ends of the left and right sides of the third roller frame 33. The two lower sets cooperate with the first track 31, and the two upper sets contact the rack 32 to form a four-point support structure to achieve smooth sliding; the double-end motor 34 is installed on the rear side of the outer surface of the third roller frame 33. The double-end motor 34 is electrically connected to the controller 5. The double-end motor 34 adopts a DC brushless servo motor with a dual output shaft structure and a built-in encoder to provide real-time feedback of motor speed and position information to the controller 5; there are two drive gears 35. 35 are respectively installed on the outside of the left and right rotating ends of the double-ended motor 34 and mesh with the left and right racks 32 respectively.

The first lead screw assembly 310 adopts a ball screw pair, and the nut is filled with circulating balls to convert sliding friction into rolling friction, so as to realize the smooth lifting and lowering of the U-shaped frame 311. The U-shaped frame 311 is installed on the rear side of the limiting end of the two first limiting assemblies 38 on the left and right sides. The left and right sides of the U-shaped frame 311 extend to the outside from the slot of the housing 37. The lead screw nut in the first lead screw assembly 310 is connected to the U-shaped frame 311.There are two third motors 312, which are respectively installed on the top left and right sides of the U-shaped frame 311. The rotating ends of the third motors 312 extend to the lower surface of the U-shaped frame 311. The third motors 312 are electrically connected to the controller 5. The third motors 312 are micro servo motors, which are connected to the rotating plate 313 through a reducer to achieve speed reduction and torque increase, so that the rotating plate 313 can generate sufficient torque to drive the actuating lever 314 to rotate. There are two rotating plates 313, which are respectively installed at the bottom of the rotating ends of the left and right third motors 312. The surface of the rotating plates 313 is treated with anti-slip material to increase the friction with the actuating lever 314. The arc shape can provide sufficient rotation range in a limited space. There are two actuating levers 314, which are respectively installed on the bottom front side of the left and right rotating plates 313. The actuating levers 314 are made of medical-grade stainless steel and the surface is mirror polished to avoid scratching surgical instruments.

[0030] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0031] Step 1: The operator places the tray containing surgical instruments smoothly on the surface of the guide frame 14. Using its own weight, the tray slides automatically along the tilt angle of the guide frame 14, eventually stopping at the designated position behind the first robotic arm 13. The operator then activates the controller 5. The pre-programmed sequence in the controller 5 triggers the first robotic arm 13, the third motor 312, the second motor 39, and the dual-end motor 34 to enter working mode. The first robotic arm 13 precisely operates, removing the surgical instruments from the tray one by one and accurately placing them in their corresponding positions on the upper surface of the mounting base 36. The third motors 312 on both sides drive their corresponding rotating plates 313 to rotate. The rotating plates 313 move the levers 314 synchronously to the corresponding positions above the surgical instrument rings. The second motor 39 drives the lead screw in the first lead screw assembly 310 to rotate, causing the lead screw in the first lead screw assembly 310 to rotate. The mother drive U-shaped frame 311, and under the limiting action of the first limiting component 38, the U-shaped frame 311 is lowered to the specified height position, and the two left and right actuating rods 314 in front of the U-shaped frame 311 are inserted into the surgical instrument finger ring. The third motors 312 on the left and right sides drive the rotating plates 313 at the corresponding positions to drive the actuating rods 314 to rotate outward, thereby fully opening the cutting edge of the surgical instrument to prepare for subsequent disinfection. The double-end motor 34 starts and drives the drive gears 35 on the left and right sides to rotate synchronously. Under the meshing action of the drive gears 35 and the rack 32, the entire instrument transfer component 3 moves backward into the inner cavity of the outer shell 11 under the guidance and limiting of the first track 31 on the left and right sides. At the same time, the second motor 39 drives the first lead screw assembly 310 to rotate in the opposite direction, so that the U-shaped frame 311 moves upward and resets, and the actuating rods 314 on the left and right sides disengage from the surgical instrument finger ring.

[0032] Step 2: The controller 5's internal preset program controls the first motor 25, controller 5, ozone water generator 6, ozone water disinfection tank 21, and first electric telescopic rod 211 to start. The first motor 25 drives the bottom rotating shaft 24 to drive the lower sprockets in the left and right sprocket assemblies 26 to rotate synchronously. Under the limiting action of the upper sprocket in the sprocket assembly 26, the chain in the sprocket assembly 26 drives the first roller frame 23. The first roller frame 23 moves upward along the inner side of the first guide rail frame 22, and the bracket 27 also rises accordingly, lifting the tank basket 28 upward from inside the ozone water disinfection tank 21. The second robotic arm 15 grabs the surgical instruments on the surface of the mounting base plate 36 and accurately places them into the inner cavity of the tank basket 28. When the number of surgical instruments placed in the inner cavity of the tank basket 28 reaches the specified requirement, the first motor 25 drives the bottom rotating shaft 24 to rotate synchronously. Shaft 24 rotates in the opposite direction. Under the transmission action of sprocket assembly 26, the first roller frame 23 moves downward along the inner side of the first guide rail frame 22. The bracket 27 then places the tank basket 28 downward on the surface of the second roller frame 210. The ozone water generator 6 delivers the prepared ozone water into the ozone water disinfection tank 21 until the ozone water completely soaks the surgical instruments in the tank basket 28. The ozone water disinfection tank 21 starts the disinfection program to disinfect the surgical instruments inside with ozone water. At the same time, the first electric telescopic rod 211 intermittently extends and retracts, driving the second roller frame 210 to reciprocate along the inner side of the second guide rail frame 29. The second roller frame 210 also drives the tank basket 28 to reciprocate synchronously, thereby enhancing the contact between the ozone water and various parts of the surgical instruments and improving the disinfection effect.

[0033] Step 3: After the disinfection process is completed, the first motor 25 starts again, causing the bracket 27 to move upward and lift the tank basket 28 out of the ozone water disinfection tank 21. The controller 5's internal preset program controls the fourth motor 45, vertical movement module 46, second electric telescopic rod 47, third electric telescopic rod 415, and fifth motor 410 to start. The fourth motors 45 on both sides drive the gears inside the gear and rack assembly 43 on both sides to rotate and move the gears inside the gear and rack assembly 43 along the rack. Under the limiting action of the second limiting components 42 on both sides, the truss 44 moves forward to the inner cavity of the outer shell 11. The vertical movement module 46 drives the second electric telescopic rod 47 to perform the first level of height adjustment. The second electric telescopic rod 47 drives the tank outer shell 48 to perform the second level of height adjustment, so that the tank outer shell 48 moves to the tank basket. At the same height position on the outer side of 28, the third electric telescopic rods 415 on both sides shorten and drive one end of the connecting rod 414 to move outward, and drive the fixed frame 413 to rotate axially at the other end of the connecting rod 414, thereby rotating the fixed frame 413 to a horizontal state. The fifth motors 410 on both sides drive the screw screw in the second screw assembly 411 at the corresponding position to rotate, so that the screw nut in the second screw assembly 411 on both sides drives the moving seat 412 at the corresponding position. The moving seats 412 on both sides move inward under the limiting action of the third limiting assembly 49 at the corresponding position, and drive the left and right fixed frames 413 to insert into the handle of the tank basket 28. With the cooperation of the fourth motor 45, the vertical moving module 46 and the second electric telescopic rod 47, the tank basket 28 is moved out of the inner cavity of the outer shell 11, completing the entire automatic cleaning and disinfection process of the medical device.
