Detailed Description of the Invention

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] AsFigures 1-11 As shown in Figures 1-11 , a mobile sterilizing and drying medical tray proposed by an embodiment of the present invention includes a bracket 1, and universal self-locking wheels 2 are provided at the bottom thereof. Preferably, the number of the universal self-locking wheels 2 is three and they are annularly distributed, which is convenient for pushing the bracket 1 to move, and belongs to the distinguishing features of the prior art of the present invention; The distinguishing technical features of the present invention further include: a tray assembly 3, which includes a bottom shell 301 provided on the bracket 1. A cover shell 302 is provided on the top of the bottom shell 301. Preferably, one end of the cover shell 302 is hinged to the bottom shell 301, and the other end is fixed to the bottom shell 301 through a locking member. A sealing ring is provided between the cover shell 302 and the bottom shell 301 to ensure the sealing performance after the two are fixed. A discharge pipe 303 is communicated with the bottom of the bottom shell 301, and a one-way valve 304 is provided on the discharge pipe 303. A mesh support plate 305 is provided in the bottom shell 301. The mesh support plate 305 is located in the middle of the bottom shell 301, and medical devices are placed on the mesh support plate 305. The design of the mesh holes on the mesh support plate 305 facilitates the downward seepage of water stains, avoiding the accumulation of water stains and affecting medical devices. The water stains can be discharged through the discharge pipe 303. Since the one-way valve 304 is provided on the discharge pipe 303, by using the one-way flow restriction of the one-way valve 304, when the cover shell 302 covers the bottom shell 301, the gas or liquid in the bottom shell 301 can flow outwards, but the outside air cannot enter the bottom shell 301; The sterilization component 4 includes a hydrogen peroxide generator 401 disposed on the bracket 1. The model of the hydrogen peroxide generator 401 is HTY-V600. It takes advantage of the fact that hydrogen peroxide in the gaseous state at room temperature has a stronger spore-killing ability than in the liquid state. By generating free hydroxyl groups, it is used to attack cell components, including lipids, proteins, and DNA tissues, to achieve the purpose of biological decontamination and sterilization. The air outlet of the hydrogen peroxide generator 401 is connected to the bottom shell 301 through a first delivery pipe 402. The first delivery pipe 402 is connected to the bottom shell 301 through a second delivery pipe 403. A gas guide member 404 is provided in the first delivery pipe 402, and the gas guide member 404 is used for circulating and guiding gas inside the tray assembly 3. Two valves 405 and a dehumidifying member 406 are provided in the second delivery pipe 403. The dehumidifying member 406 is used for dehumidifying during the internal circulation of the gas. Preferably, the two valves 405 are respectively located at both ends of the second delivery pipe 403, and the two valves 405 are respectively close to the first delivery pipe 402 and the bottom shell 301. The bottom shell 301 includes a straight cylinder section and a tapered cylinder section that are connected. The first delivery pipe 402 is connected to the straight cylinder section, and the second delivery pipe 403 is connected to the tapered cylinder section. The mesh support plate 305 is located between the connection ports of the first delivery pipe 402 and the second delivery pipe 403. When the cleaned medical device is placed on the mesh support plate 305 and the cover shell 302 is fixed to the bottom shell 301, at this time, the two valves 405 on the second delivery pipe 403 are closed. The hydrogen peroxide generator 401 generates hydrogen peroxide vapor and transports the hydrogen peroxide vapor to the inside of the bottom shell 301 through the first delivery pipe 402. As the hydrogen peroxide vapor is continuously transported, the air pressure inside the bottom shell 301 will gradually increase. Under the action of the air pressure, in cooperation with the one-way flow of the one-way valve 304, the original air inside the bottom shell 301 is discharged. When discharging the original air, the outside air will not enter the bottom shell 301. When the bottom shell 301 is completely filled with hydrogen peroxide vapor, the hydrogen peroxide generator 401 is closed. At this time, on the premise of continuing to transport the hydrogen peroxide vapor, the air pressure inside the bottom shell 301 will not increase, and the one-way valve 304 will not open, so that an independent sterilization chamber relying on hydrogen peroxide vapor for sterilization is formed inside the bottom shell 301. The gaseous hydrogen peroxide vapor can effectively sterilize the medical device. The vapor can penetrate complex instruments and effectively cover the surface or corners of the device (such as the joint gaps of surgical forceps), ensuring all-round sterilization and meeting the medical sterilization standards. When the hydrogen peroxide vapor sterilizes for a period of time, the hydrogen peroxide vapor will decompose. It will decompose into water and oxygen. The amount of water produced is very small, mainly oxygen, and there will be no harmful residues between the two, ensuring environmental protection and hygiene performance. Since a large amount of oxygen is generated during the decomposition process, therefore, the air pressure inside the bottom shell 301 will gradually increase. The increase in air pressure is used to trigger the opening and closing of the one-way valve 304, so that it can discharge air unidirectionally outward during the decomposition process, and the water produced by the decomposition is discharged by the way during the exhaust process. It should be noted that the water discharged at this time refers to the water produced by the decomposition. Affected by the vapor,A small amount of water stains will also adhere to the surface of the medical device. After sterilization is completed, the hydrogen peroxide generator 401 can be restarted. It conveys hydrogen peroxide vapor to the bottom shell 301 again. Using this vapor (with less water before decomposition), the medical device after sterilization is initially blown. Through the initial blowing, the water stains on the surface of the medical device can be reduced, playing a role in initial blowing and drying. At the same time, the pressure in the bottom shell 301 is increased again by the conveyed hydrogen peroxide vapor, so as to force the one-way valve 304 to open effectively and stably, for discharging the oxygen and water decomposed during the sterilization process. The restart time of the hydrogen peroxide generator 401 does not need to be too long. After the initial blowing, it is closed again. At this time, the valves 405 at both ends of the second delivery pipe 403 are opened. The first delivery pipe 402, the second delivery pipe 403, and the bottom shell 301 are connected to balance the pressure in the bottom shell 301. At this time, the one-way valve 304 is closed, and then the air flow is circulated internally through the air guiding member 404. Since the mesh support plate 305 is located between the connection ports of the first delivery pipe 402 and the second delivery pipe 403, when the air flow circulates internally, it will blow the medical device. At the same time, when the air flow circulates internally, it will flow along the second delivery pipe 403. The dehumidifying member 406 dehumidifies the air flow, making the air flow dry. The dry air flow is circulated internally to blow the medical device, thereby drying the medical device; In this solution, the hydrogen peroxide generator 401 is used to generate hydrogen peroxide vapor and convey it into the bottom shell 301, discharging the original air. Then, the medical device is sterilized using the hydrogen peroxide vapor. After sterilization is completed, the hydrogen peroxide generator 401 is restarted again, which is not only used to discharge the excess water and oxygen generated by decomposition, but also can initially blow and dry the medical device. Then, the air flow is circulated internally through the air guiding member 404, cooperating with the dehumidifying member 406, thereby drying the medical device after sterilization is completed. During the sterilization and drying processes, by introducing hydrogen peroxide vapor and discharging it unidirectionally through the one-way valve 304, external contamination is prevented and the internal sterile state is maintained.

[0019] Such as Figure 7As shown, a further technical solution of the present invention for the transportation of hydrogen peroxide vapor is disclosed. An annular groove 19 is formed in the inner wall of the bottom support shell 301. An annular baffle 5 for blocking the annular groove 19 is arranged in the bottom support shell 301. One end of the first delivery pipe 402 away from the hydrogen peroxide generator 401 is communicated with the annular groove 19. A plurality of spray pipes 6 distributed in a ring shape are communicated with the inner side wall of the annular baffle 5. By providing the annular groove 19 and arranging the annular baffle 5, an annular cavity is formed on the inner wall of the bottom support shell 301. First, the hydrogen peroxide vapor is transported into the annular cavity, and then it is ejected through the plurality of spray pipes 6. Preferably, the spray pipes 6 are inclined, so that the hydrogen peroxide vapor enters the bottom support shell 301 at multiple points in a ring shape, which not only improves the sterilization effect on medical devices, but also improves the blowing and drying effect on them.

[0020] As Figure 7 shown, a further technical solution of the present invention for the annular baffle 5 is disclosed. The annular baffle 5 is rotatably connected to the bottom support shell 301. A plurality of paddles 7 are fixedly arranged on the outer side wall of the annular baffle 5. Preferably, the paddles 7 are inclined. When the hydrogen peroxide vapor is transported into the annular groove 19, the hydrogen peroxide vapor will impact the paddles 7, thereby driving the annular baffle 5 to rotate. By using the rotation of the annular baffle 5 and cooperating with the plurality of spray pipes 6, the hydrogen peroxide vapor is evenly transported into the bottom support shell 301, so that the hydrogen peroxide vapor is evenly distributed in the bottom support shell 301, thereby improving the sterilization effect on medical devices and improving the blowing and drying effect on medical devices.

[0021] As Figure 6 and Figure 10As shown, the specific structure of the air guiding member 404 of the present invention is disclosed. The air guiding member 404 includes a mounting frame 4041 disposed in the first delivery pipe 402. Preferably, the mounting frame 4041 includes a rotating ring coaxial with the first delivery pipe 402. There are support rods connected between the rotating ring and the inner wall of the first delivery pipe 402. A wind blade shaft 4042 is rotatably provided on the mounting frame 4041. The wind blade shaft 4042 includes a shaft rod that rotatably penetrates the rotating ring. A plurality of blades distributed in a ring shape are configured on the outer surface of the shaft rod. The blades are inclined. A guide rod 4043 rotatably penetrates the first delivery pipe 402. One end of the guide rod 4043 is connected to a motor 4044 provided on the first delivery pipe 402. The guide rod 4043 is drivingly connected to the wind blade shaft 4042 through a first bevel gear assembly 4045. When delivering hydrogen peroxide vapor for sterilization, the valve 405 on the second delivery pipe 403 is closed. The motor 4044 does work, and its output shaft drives the guide rod 4043 to rotate. When the guide rod 4043 rotates, under the linkage of the first bevel gear assembly 4045, the wind blade shaft 4042 is driven to rotate, thereby increasing the flow rate of the vapor in the first delivery pipe 402. Utilizing the increased flow rate and cooperating with the blowing on the deflector 7, it is ensured that the annular baffle 5 rotates effectively. When performing air flow internal circulation, when the second delivery pipe 403 is in a communicating state, since the hydrogen peroxide generator 401 is in a closed state, therefore, while exhausting air and pressurizing at one end, the other end will suck air and induce wind, thereby forcing the air flow to circulate internally along the first delivery pipe 402, the second delivery pipe 403, and the bottom shell 301, and cooperating with the dehumidifying member 406 to ensure blowing and drying of medical devices. The air guiding member 404 realizes the function of a blower, but is different from a conventional blower. The motor 4044 is externally provided, will not be corroded by hydrogen peroxide vapor, and will not affect the sterilization of hydrogen peroxide vapor.

[0022] As Figure 8As shown, the specific structure of the dehumidifying member 406 of the present invention is disclosed. The dehumidifying member 406 includes a through groove 4061 formed in the second delivery pipe 403. An arc-shaped plate 4062 for blocking the through groove 4061 is detachably installed on the second delivery pipe 403. Arc-shaped grooves 4063 are formed in the inner walls of both the second delivery pipe 403 and the arc-shaped plate 4062. A mesh box 4064 for placing desiccant is movably inserted into the two arc-shaped grooves 4063. Preferably, the desiccant is in granular form. After the desiccant is placed in the mesh box 4064, there are gaps between the granules, which not only facilitates the flow of air but also adsorbs the moisture in the air. First, the mesh box 4064 is inserted into the arc-shaped plate 4062, and then the arc-shaped plate 4062 blocks the through groove 4061. At this time, the mesh box 4064 is located inside the second delivery pipe 403. When the air flows along the second delivery pipe 403, it will pass through the desiccant, and the desiccant absorbs the moisture in the air. The dried gas then blows and dries the medical device. Although this solution uses desiccant for dehumidification, during the sterilization and decomposition process, the valves 405 at both ends of the second delivery pipe 403 are in a closed state, so that the moisture in the hydrogen peroxide vapor will not affect the desiccant during the sterilization or decomposition process. After the sterilization and decomposition, the hydrogen peroxide generator 401 needs to be turned on again. The steam generated by it triggers the one-way valve 304 to discharge the excess moisture generated by decomposition in advance. After the discharge, the hydrogen peroxide generator 401 is turned off again. At this time, there is less residual moisture in the gas of the bottom shell 301. Then the valve 405 is opened, and the desiccant only adsorbs and dehumidifies the gas inside the bottom shell 301. Since the desiccant can be detachably replaced and the volume of the bottom shell 301 is not large and the gas capacity inside it is not much, the dehumidification requirement can be met by replacing the desiccant regularly according to the schedule.

[0023] As Figure 8As shown, a further technical solution for replacing the desiccant of the present invention is disclosed. A U-shaped frame 8 is fixedly provided on the second conveying pipe 403. Two vertical rods 9 are slidably passed through the U-shaped frame 8. An arc plate 4062 is fixedly provided at the top of the two vertical rods 9. A resistance spring 10 sleeved on the vertical rod 9 is installed between the arc plate 4062 and the U-shaped frame 8. In the initial state, under the elastic force of the resistance spring 10, the arc plate 4062 is buckled and blocked by the through groove 4061. When it is necessary to remove the net box 4064 to replace the desiccant, the vertical rod 9 is pulled downward, thereby driving the arc plate 4062 to move downward and squeeze the resistance spring 10, so that the arc plate 4062 is away from the second conveying pipe 403. At this time, the net box 4064 can be removed. 4. After replacing the desiccant, insert the net box 4064 into the arc groove 4063 on the arc plate 4062, and then loosen the vertical rod 9. Under the elastic force of the resistance spring 10, the arc plate 4062 is driven to reset, so that the arc plate 4062 blocks the through groove 4061 again. In order to make the solution more reasonable, it should be noted that a sealing gasket is provided on the arc plate 4062, and the resistance spring 10 adopts high elastic strength. Under the elastic force of the resistance spring 10, the sealing gasket is cooperated, so that the arc plate 4062 has a good sealing effect after being buckled into the through groove 4061. When replacing the net box 4064, you only need to pull the vertical rod 9 hard to slide it, without the help of tools. The replacement method is simple and convenient.

[0024] like Figure 8 and Figure 11 As shown, the present invention discloses a further technical solution for the net box 4064. A spline cylinder 11 is rotated and penetrated on the second conveying pipe 403. The spline cylinder 11 is connected to the guide rod 4043 through the second bevel gear assembly 12. A spline rod 13 is slidably inserted in the spline cylinder 11. A spline groove 14 is provided on the net box 4064. The spline rod 13 is plugged into the spline groove 14. When the net box 4064 is installed in the second conveying pipe 403, the spline rod 13 is slid so that the end of the spline rod 13 is movably inserted into the spline groove 14. The spline rod 13 is tightly inserted and matched with the spline cylinder 11 and the spline groove 14, so that the stability of the connection can be ensured after insertion. When the motor 4044 drives the guide rod 4043 to rotate, the second bevel gear assembly 12 is linked to drive the spline cylinder 11 to rotate synchronously. The spline matching of the spline cylinder 11, the spline rod 13 and the spline groove 14 can drive the mesh box 4064 to rotate. By driving the mesh box 4064 to rotate, the activity of the desiccant therein is increased, thereby preventing the desiccant from piling up and affecting the normal passage of airflow.

[0025] like Figure 9As shown in the figure, the specific structure of the mesh box 4064 of the present invention is disclosed. The mesh box 4064 includes a box body 40641. One side of the box body 40641 is threadedly inserted with a box cover 40642. The inner wall of the box body 40641 is provided with a plurality of partition plates 40643. A bearing wheel 40644 is sleeved on the box body 40641. The bearing wheel 40644 is rollingly inserted into two arc-shaped grooves 4063. The threaded fit between the box body 40641 and the box cover 40642 is convenient for opening or closing, and is convenient for replacing the desiccant. By arranging a plurality of partition plates 40643 in the box body 40641, the box body 40641 is divided into a plurality of storage areas, and the plurality of storage areas are annularly distributed, which is convenient for separating and placing the desiccant, so that when the box body 40641 rotates, the disturbance performance of the desiccant is better. By arranging the bearing wheel 40644 on the box body 40641, through the insertion fit between the bearing wheel 40644 and the arc-shaped groove 4063, it is not only convenient for installing and positioning the mesh box 4064, but also makes the overall rotation of the mesh box 4064 smoother, thereby improving the practicability.

[0026] As Figure 7 shown, a further technical solution of the present invention for the bottom support shell 301 is disclosed. A plurality of insertion cylinders 15 are constructed on the inner wall of the bottom support shell 301. A plurality of insertion rods 16 are constructed on the bottom of the mesh support plate 305. The plurality of insertion rods 16 are respectively inserted and matched with the plurality of insertion cylinders 15. By arranging the insertion cylinders 15 on the bottom support shell 301 and arranging the insertion rods 16 inserted and matched with the insertion cylinders 15 on the mesh support plate 305, the mesh support plate 305 and the bottom support shell 301 are detachably connected, and the disassembly is convenient. At the same time, the mesh support plate 305 can be taken out from the bottom support shell 301, and the insertion rod 16 can be used as a support column, which is convenient for placing the mesh support plate 305 on the workbench and supporting and placing the mesh support plate 305, thereby improving the practicability.

[0027] As Figure 3 and Figure 4 shown, a further technical solution of the present invention for the discharge pipe 303 is disclosed. A collection cylinder 17 is threadedly sleeved on the end of the discharge pipe 303. A plurality of air permeable grooves 18 are opened on the collection cylinder 17. Since there is water stain on the surface of the medical device after cleaning, the water stain will flow downward and be discharged. At the same time, water will also be generated after the decomposition of hydrogen peroxide vapor sterilization. When the water is discharged, it is collected by the collection cylinder 17 to avoid directly discharging the water liquid on the ground and affecting the surrounding environmental hygiene. Preferably, the air permeable grooves 18 are located at the upper end of the outer surface of the collection cylinder 17. Without affecting the collection of the water liquid, it does not affect the normal discharge of the air flow. The threaded connection mode of the collection cylinder 17 and the discharge pipe 303 is convenient for installing or disassembling the collection cylinder 17.

[0028] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
