Description

Technical Field

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

[0002] In the medical field, sterilization and disinfection of equipment is a crucial link, which is directly related to the patient's treatment safety and the occupational health of medical staff. Through strict sterilization and disinfection of medical equipment, cross infection can be effectively prevented, the hospital infection rate can be reduced, and the patient's life safety can be guaranteed. The main purpose of sterilization and disinfection of medical equipment is to eliminate or kill pathogenic microorganisms on the surface and inside of the equipment, including but not limited to bacteria, viruses, fungi and spores, etc., to ensure the sterility of the equipment during use. This helps prevent pathogens from being transmitted to patients or medical staff through equipment, reduce the risk of hospital infection, and improve medical quality and safety.

[0003] With the continuous advancement of medical technology, a variety of sterilization and disinfection equipment has emerged. However, high-pressure steam sterilization stands out among many methods because of its high efficiency, reliability, pollution-free, and adaptability to more equipment of different materials. It has become the preferred method for sterilization and disinfection of medical equipment. Existing high-pressure steam sterilization and disinfection equipment generates high-pressure steam by heating water, causing the protein in the microorganism to denature and lose its original structure and function. When adding water, there are generally certain requirements for the liquid level, which is not easy to be too high or too low. When the water level is too high, it is easy to cause pressure relief and water immersion of the equipment. If it is too low, the heating element may be directly exposed to the air, resulting in excessively high local temperatures, which will not only damage the equipment, but also affect the uniform generation and distribution of steam, thereby reducing the sterilization effect.

[0004] Existing equipment can monitor the water level, and the equipment will alarm when the water level is too high or too low. However, due to differences in the material of the equipment, usage scenarios, etc., the sterilization time will also be adaptively changed. When the sterilization time becomes longer, it means that the greater the water consumption of a single sterilization, the more likely it is that the water level will be too low. Therefore, in response to this situation, personnel are often required to supervise during long-term sterilization and disinfection. When the water level is too low and the alarm sounds, the user needs to replenish the water in time, which is not convenient during use.

[0005] For this reason, we propose a medical sterilization and disinfection device. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1 See also Figures 1 to 10 The present invention provides a technical solution: a medical sterilization and disinfection device, comprising: a tank body 1 and a cover body 2, the cover body 2 is installed on the top of the tank body 1, and a placement tray 3 is installed inside the tank body 1; the placement tray 3 is provided in plurality and is arranged in sequence from top to bottom from the height of the tank body 1, a connecting rod 16 is installed between adjacent placement trays 3, and a plurality of placement trays 3 are fixed together by the connecting rod 16, and further comprising: a flow guide 4 and a recovery trough 5, the flow guide 4 is fixedly installed at the bottom of the placement tray 3, the recovery trough 5 is arranged at the bottom of the flow guide 4, and the flow guide 4 is fixedly installed at the bottom of the placement tray 3, and ... recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 is arranged at the bottom of the flow guide 4, and the recovery trough 5 A water outlet pipe 17 is provided at the bottom of the flow cover 4, and the flow guide cover 4 and the recovery tank 5 guide the condensed water generated during the sterilization and disinfection process of the equipment; a water storage chamber 6 and a ring 7, the water storage chamber 6 is provided at the bottom of the tank body 1, the ring 7 is fixed on the top of the water storage chamber 6, and a high plate 8 and a low plate 9 are installed on the outer side of the ring 7, and the high plate 8 and the low plate 9 collect the generated condensed water; a detection component 10, the detection component 10 is installed in the low plate 9, and the detection component 10 detects the water level change in the water storage chamber 6 and automatically replenishes the condensed water in the low plate 9 into the water storage chamber 6.

[0022] Through the above technical solution, the cover body 2 seals the tank body 1, and ensures that the tank body 1 is in a relatively sealed environment during sterilization to avoid pressure leakage. Secondly, the equipment to be sterilized is placed on the placement tray 3. During the process of heating to generate steam, there is a temperature difference between the steam and the equipment and the inner wall of the tank body 1, so that condensation is generated on the equipment and the tank body 1. The condensation generated by the tank body 1 is collected on the high plate 8 under the action of its own gravity, and finally transferred from the high plate 8 to the low plate 9. In this process, a relatively high water storage space is formed between the high plate 8 and the inner wall of the tank body 1, and a relatively low water storage space is formed between the low plate 9 and the inner wall of the tank body 1. The condensation generated by the equipment will fall into the deflector 4 through the placement plate 3, and enter the recovery tank 5 through the water outlet pipe 17 at the bottom of the deflector 4. Similarly, condensation will also be generated at the bottom of the deflector 4, and the condensation generated on the deflector 4 will also flow into the recovery tank 5 through the conical structure of the deflector 4. The condensation water collected by the recovery tank 5 will fall on the high plate 8 and finally be collected on the low plate 9. Therefore, the condensation water generated by the tank body 1, the equipment and the deflector 4 will be collected by the water storage space formed by the low plate 9 and the tank body 1. During the sterilization process of the tank body 1, the tank body 1 has a certain temperature because of the steam generated inside, so the collected condensation water can be preheated; During the entire process of sterilization and disinfection, the detection component 10 will monitor the liquid level in the water storage chamber 6 in real time. When the sterilization and disinfection time is relatively long, the water level in the water storage chamber 6 decreases. When it decreases to the threshold value, the detection component 10 will be activated to automatically return the preheated condensed water collected in the low plate 9 to the water storage chamber 6, thereby increasing the liquid level in the water storage chamber 6, thereby avoiding the situation where the heating elements may be directly exposed to the air due to the long sterilization and disinfection time and the inability to replenish water in time, resulting in the inability to replenish water in time, causing the water level to be caused. The situation, resulting in local excessive temperature, damage to equipment, and affecting the uniform generation and distribution of steam. Therefore, the condensed water generated can be collected during the entire process to prevent the condensed water from dripping directly into the water storage chamber 6. Secondly, there is no need for special personnel to supervise for a long time of sterilization and disinfection, and the effect of automatic water replenishment can be achieved. The replenished water is preheated, and when added to the water storage chamber 6, the temperature difference of the water storage chamber 6 can be reduced as much as possible, the variation range of the steam temperature can be reduced, and the sterilization and disinfection effect can be improved.

[0023] Specifically, in this embodiment, the detection component 10 includes a vertical tube 11 fixed in the low plate 9, a horizontal tube 12 is fixedly installed on one side of the vertical tube 11, a blocking block 13 is slidably installed inside the vertical tube 11, a movable rod 14 is fixedly installed at the bottom of the blocking block 13, the movable rod 14 is slidably connected to the vertical tube 11, a float 15 is fixedly installed at the bottom of the movable rod 14, and the float 15 is arranged inside the water storage chamber 6.

[0024] Through the above technical solution, after the water level in the water storage chamber 6 is replenished, the float 15 floats above the liquid surface. As the water is consumed by sterilization and disinfection, the liquid level in the water storage chamber 6 gradually decreases, and the float 15 always floats on the liquid surface. When the liquid level decreases, the float 15 will move downward synchronously. When the float 15 moves downward, it will slide in the vertical pipe 11 through the movable rod 14, and at the same time drive the blocking block 13 to move downward. When the blocking block 13 moves downward, it gradually moves away from the connection port between the vertical pipe 11 and the horizontal pipe 12. At this time, the connection port between the vertical pipe 11 and the horizontal pipe 12 is opened, and the condensed water stored in the low plate 9 will flow out through the horizontal pipe 12 and finally flow into the water storage chamber 6 to realize the water replenishment of the water storage chamber 6. After the water replenishment, the liquid level in the water storage chamber 6 will rise again. At this time, the float 15 will also drive the blocking block 13 again to block the connection port between the vertical pipe 11 and the horizontal pipe 12 to prevent the liquid level in the water storage chamber 6 from being higher than the threshold.

[0025] Embodiment 2 After sterilization, since the surface of the placement tray 3 and the equipment is still at a relatively high temperature after being subjected to high temperature, it is often necessary to wait for a period of time before taking out the equipment after opening the cover body 2. However, in the process of cooling the equipment while the cover body 2 is opened, due to the uncertainty of the external environment, the sterilized equipment may be re-contaminated, and the longer it is exposed to the external environment, the greater the chance of infection. Therefore, a water adding mechanism 18 is installed inside the tank body 1. The water adding mechanism 18 can not only add water to the water storage chamber 6, but also cool the sterilized equipment and the placement tray 3.

[0026] Specifically, the water adding mechanism 18 includes an annular tube 19 fixed on the top of the tank body 1, and a water inlet pipe 20 is fixedly installed at the bottom of the annular tube 19. The bottom of the water inlet pipe 20 is located inside the water storage chamber 6. A plurality of cooling components 21 are installed on the side of the water inlet pipe 20. The cooling components 21 cool the placement plate 3 when adding water, and the cooling components 21 include a cooling pipe 22 fixed on the side of the water inlet pipe 20. The cooling pipe 22 is inclined upward, and a rotating shaft 23 is rotatably installed inside the cooling pipe 22. An impeller 24 is fixedly installed at one end of the rotating shaft 23. The impeller 24 is located inside the water inlet pipe 20, and a fan blade 25 is fixedly installed at the other end of the rotating shaft 23.

[0027] Through the above technical solution, when adding water to the water storage chamber 6, it is only necessary to add water into the annular tube 19. The water entering the annular tube 19 will flow into the water inlet pipe 20 and enter the water storage chamber 6 through the water inlet pipe 20. At the same time, when the water flows through the water inlet pipe 20, the water flow acts on the impeller 24, driving the impeller 24 to rotate. When the impeller 24 rotates, it drives the rotating shaft 23 to rotate synchronously. When the rotating shaft 23 rotates, it drives the fan blades 25 to rotate. When the fan blades 25 rotate, they can carry the water-cooled air flow out from the cooling tube 22, and the ejected cold air acts on the placement tray 3 and the equipment in the placement tray 3, so that they are cooled quickly, thereby reducing the exposure time of the equipment to the external environment after sterilization.

[0028] In addition, the placement plate 3 is slidably installed inside the tank body 1, that is, a slide rail 40 is fixedly installed on the inner side of the tank body 1, and a limiting wheel 41 is fixedly installed on the outer side of the placement plate 3, so that the placement plate 3 can be installed in the slide rail 40 through the limiting wheel 41, and a winding mechanism 26 is installed on the outer side of the tank body 1. When the winding mechanism 26 is actuated, the placement plate 3 is transferred from the inside of the tank body 1 to the outside, wherein the winding mechanism 26 includes a first winding wheel 27 and a second winding wheel 28 rotating on both sides of the tank body 1, and a traction rope 42 is wound around the outer sides of the first winding wheel 27 and the second winding wheel 28, a first transmission rod 29 is fixedly installed inside the first winding wheel 27, and a second transmission rod 30 is rotatably installed inside the second winding wheel 28, and a transmission member 31 is connected between the first transmission rod 29 and the second transmission rod 30, and when the first transmission rod 29 rotates, the second transmission rod 30 is synchronously driven to rotate through the transmission member 31; The transmission member 31 includes a main pulley 35 fixed to the end of the first transmission rod 29 and a slave pulley 36 rotatably installed on the outside of the tank body 1, a transmission belt 37 is installed between the main pulley 35 and the slave pulley 36, a first gear 38 is coaxially installed on the slave pulley 36, a second gear 39 is meshed with one side of the first gear 38, and the second gear 39 is fixed to the end of the second transmission rod 30.

[0029] Through the above technical solution, after being cooled by the cooling member 21, the user can rotate the first transmission rod 29. When the first transmission rod 29 rotates, it drives the main pulley 35 to rotate. When the main pulley 35 rotates, it drives the slave pulley 36 to rotate through the transmission belt 37. When the slave pulley 36 rotates, it drives the first gear 38 to rotate. The first gear 38 is meshed with the second gear 39 to drive the second gear 39 to rotate. When the second gear 39 rotates, the second transmission rod 30 will also rotate synchronously, thereby driving the second winding wheel 28 to rotate. When the first winding wheel 27 and the second winding wheel 28 are both rotated, the traction rope 42 will be wound up, so that the placement disk 3 has an upward traction force, driving the placement disk 3 to be transferred out of the tank body 1. At this time, the placement disk 3 and the equipment on the placement disk 3 are away from the residual temperature in the tank body 1. They are cooled by the external environment, which can further reduce the residence time of the equipment after sterilization and disinfection. The placement disk 3 is transferred by rotation, which also avoids scalding and is safer during operation.

[0030] It should be added that a mounting seat 32 is fixedly installed on the side of the tank body 1, and the first winding wheel 27 and the second winding wheel 28 are rotatably installed in the mounting seat 32. A ratchet 33 is fixedly installed on the outer wall of the first transmission rod 29, and a pawl 34 is engaged with the top of the ratchet 33. The pawl 34 is rotatably installed on the top of the mounting seat 32. When the traction rope 42 is wound up, the ratchet 33 will also rotate synchronously with the rotation of the first transmission rod 29. At this time, the pawl 34 is not engaged with the ratchet 33. When the first transmission rod 29 is released, the placement plate 3 will fall under the action of its own gravity, that is, the second transmission rod 30 will be driven to reverse, but at this time the pawl 34 restricts the ratchet 33 and prevents it from reversing. Therefore, the placement plate 3 can be stopped at any position according to the needs of the operator.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
