Description

Technical Field

[0001] The present invention belongs to the technical field of steam disinfection, and particularly relates to a disinfection device for urological nursing. Background Art

[0002] In the field of urological nursing, the disinfection of medical devices is of crucial importance. Currently, existing disinfection technologies mainly include ultraviolet disinfection, high-temperature steam disinfection, alcohol disinfection, etc. Among them, steam disinfection mainly disinfects by diffusely emitting steam, using high-temperature and high-pressure steam to kill bacteria, viruses, and other microorganisms, and has the characteristics of high efficiency, broad spectrum, and environmental protection.

[0003] Diffuse steam disinfection has the following defects:

[0004] (1) Lack of pertinence. The steam is evenly distributed in the disinfection space and cannot perform centralized disinfection on specific areas or instruments, resulting in incomplete disinfection in some areas and increasing the risk of infection.

[0005] (2) Low efficiency. Since the steam is evenly emitted, it takes a long time to achieve an ideal disinfection effect and cannot meet the need for rapid disinfection.

[0006] (3) After the steam disinfection operation is completed, there will be a lot of moisture attached to the surface of the instrument. If it cannot be dried in time, bacteria and other microorganisms are extremely likely to breed. Summary of the Invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a disinfection device for urological nursing. Through the precise design of the integrated conveying pipeline and air injection holes and the linkage control of the closing injection assembly, the directional sequential injection of steam is realized, greatly improving the disinfection efficiency and concentrating on treating key parts. At the same time, the real-time linkage of the vibration sensor and the central processor automatically switches to the air drying mode, forming an integrated automatic control process. The high-efficiency and energy-saving steam preheating and double injection disinfection ensure a thorough disinfection effect, avoid the growth of bacteria, meet the clinical rapid turnover requirements, significantly optimize the operation process, and reduce energy consumption.

[0008] The technical solution adopted by the present invention is as follows: A disinfection device for urological nursing, including a bottom plate, a support column vertically and fixedly arranged on the upper wall of the bottom plate, and a top plate horizontally and fixedly arranged at the upper end of the support column. A disinfection barrel is fixedly arranged on the bottom plate. A top cover is slidably arranged on the circumferential outer wall of the support column. The top cover can move up and down during the disinfection process to seal the disinfection barrel and form a closed disinfection space. The disinfection barrel is used to provide a disinfection space for the instruments to be disinfected. A reset tension spring is connected between the top plate and the top cover. A closing and spraying assembly is arranged between the top plate and the top cover. A water storage barrel is fixedly arranged on the lower wall of the bottom plate. An air drying assembly is arranged on the water storage barrel. An air pipe is fixedly arranged on the circumferential side wall of the water storage barrel. One end of the air pipe is connected to the inside of the water storage barrel in a penetrating manner, and the other end of the air pipe is connected to the closing and spraying assembly. A placement cage is fixedly arranged on the lower wall of the top cover. A cage door is arranged on the placement cage. The placement cage is used to place urological nursing instruments to be disinfected. The water storage barrel is used to store water for generating steam. An electric heating pipe is arranged in the water storage barrel.

[0009] As a preferred technical solution of this scheme, a conveying pipeline is vertically and fixedly arranged on the upper wall of the bottom plate. The lower end of the conveying pipeline is connected to the inside of the water storage barrel in a penetrating manner. The upper end of the conveying pipeline is fixedly provided with a guiding column. The upper end of the guiding column is vertically and fixedly connected to the bottom wall of the top plate. Spray holes are formed on the circumferential side wall of the conveying pipeline. The spray holes are located inside the disinfection barrel and are used to spray steam into the disinfection barrel to spray steam on the instruments to be disinfected.

[0010] As a preferred technical solution of this scheme, the air drying assembly includes an air pump fixedly arranged on the outer wall of the bottom of the water storage barrel, a transmission pipe fixedly arranged through the side wall of the water storage barrel, a bent pipe vertically slidably arranged in the transmission pipe, and a blowing head fixedly arranged at the free end of the bent pipe. The blowing head corresponds to the placement cage and is fixedly connected to the bottom wall of the top cover. The air pump is used to air-dry the instruments after disinfection. The transmission pipe and the bent pipe are used to transmit and guide the air flow direction. The blowing head is used to blow out the air flow to air-dry the disinfected instruments.

[0011] As a preferred technical solution of this scheme, the closing and spraying assembly includes a pressure relief valve one fixedly arranged through the top plate, an air cylinder vertically fixedly arranged on the bottom wall of the top plate, a piston fittingly and movably arranged in the air cylinder, a pressure relief valve two fixedly arranged on the upper wall of the piston, and a connecting column vertically fixedly arranged at the lower end of the piston. The lower end of the connecting column is fixedly connected to the upper wall of the top cover. The pressure relief valve one is connected to the inside of the air cylinder in a penetrating manner. Through holes are formed in the piston and the connecting column, and the through holes penetrate through the connecting column and the top cover. The pressure relief valve two is connected to the through holes in a penetrating manner. The pressure relief valve one is used to adjust the air pressure in the air cylinder and allow steam to enter the air cylinder when the air pressure reaches a certain threshold. The pressure relief valve two is used to release steam when the air pressure exceeds the threshold, so that the steam enters the disinfection barrel through the through holes. The through holes can allow the steam to pass through and smoothly enter the disinfection barrel.

[0012] As a preferred technical solution of this scheme, a sealing gasket is fixedly arranged on the lower wall of the top cover. The sealing gasket corresponds to the outer edge of the top of the disinfection barrel. When the sealing gasket contacts the upper edge of the disinfection barrel, the air injection holes correspond to the placement cage.

[0013] As a preferred technical solution of this scheme, a vibration sensor is fixedly arranged on the upper wall of the top cover, and a central processor is fixedly arranged on the upper wall of the bottom plate. The central processor is electrically controlled and connected to the vibration sensor. The central processor is electrically controlled and connected to the air pump and the electric heating tube. The vibration sensor is used to detect the vibration state of the top cover and transmit the signal to the central processor. The central processor is used to receive the signal of the vibration sensor, control the start of the air pump and the stop of the electric heating tube, and realize the automatic control of the disinfection device.

[0014] As a preferred technical solution of this scheme, the air output volume of the air injection holes is smaller than the amount of steam generated inside the water storage barrel, and its function is to gradually increase the air pressure inside the water storage barrel and the air pipe.

[0015] As a preferred technical solution of this scheme, the threshold value of the first pressure relief valve is smaller than the threshold value of the second pressure relief valve. Its function is to realize sequential hierarchical pressure control by setting different threshold values. The first pressure relief valve relieves pressure first at a lower pressure level, while the second pressure relief valve relieves pressure at a higher pressure level.

[0016] After adopting the above structure, the beneficial effects of the present invention are as follows:

[0017] (1) Integrating the linkage control of the aperture design of the conveying pipeline and the air injection holes and the closing injection assembly, and realizing the directional sequential distribution of steam through the air pressure threshold triggering mechanism. When the steam pressure difference in the water storage barrel breaks through the preset value, the top cover is driven to move to seal the disinfection barrel, and the steam is sprayed into the instruments in the placement cage through the air injection holes and the through holes; compared with the steam coverage efficiency of the traditional diffuse disinfection, it is effectively improved, and the problem that the traditional diffuse steam disinfection cannot centrally process the key parts is solved. At the same time, relying on the real-time linkage of the vibration sensor and the central processor, the air drying mode is automatically switched to form an integrated automatic control process;

[0018] (2) Through the efficient directional spraying disinfection method, the device realizes rapid disinfection, greatly shortens the disinfection cycle, meets the needs of rapid clinical turnover, and significantly improves the disinfection efficiency and optimizes the operation process compared with the traditional inefficient diffuse disinfection method;

[0019] (3) The device preheats the air flow by using the residual heat of the hot water in the water storage barrel, realizes an energy-saving and environmental-friendly disinfection process, not only reduces the energy consumption, but also maintains the high-efficiency and broad-spectrum nature of disinfection. Compared with the traditional high-energy-consuming disinfection equipment, the present invention has made remarkable progress in energy conservation and consumption reduction;

[0020] After disinfection, the air-drying component promptly blows air on the instruments to quickly remove the surface moisture, preventing the growth of bacteria, ensuring the durability of the disinfection effect, and effectively overcoming the problem that instruments are prone to contamination when wet after traditional disinfection;

[0021] (5) Flexibly control the disinfection time: By adjusting the power of the electric heating tube, the generation amount of steam is controlled, and then the disinfection time can be flexibly adjusted, making the disinfection process more flexible and enabling the adjustment of the disinfection time according to different disinfection requirements;

[0022] (6) Dual steam injection disinfection to ensure thorough disinfection effect: During the disinfection process of this device, first, steam is injected into the nursing instruments in the placement cage through the conveying pipeline and the air injection holes to ensure that the surfaces of the instruments are subjected to preliminary high-temperature disinfection treatment; Subsequently, when the air pressure in the air cylinder exceeds the threshold of the second pressure relief valve, the steam passes through the piston, the connecting column, and the top cover again through the through hole, and steam is injected into the nursing instruments in the placement cage again. This dual steam injection disinfection mechanism improves the thoroughness of disinfection, ensures that the instruments to be disinfected can be effectively disinfected at multiple angles and levels, reduces the survival rate of bacteria and viruses, and improves the disinfection efficiency.

The upper end of the conveying pipeline 23 is fixedly provided with a guide post 22, and the upper end of the guide post 22 is vertically and fixedly connected to the bottom wall of the top plate 3. The circumferential side wall of the conveying pipeline 23 is provided with air spraying holes 24, and the air spraying holes 24 are located inside the disinfection bucket 5.

[0035] The air drying assembly 27 includes an air pump 15 fixedly arranged on the outer wall of the bottom of the water storage bucket 8, a transmission pipe 16 fixedly arranged through the side wall of the water storage bucket 8, an elbow pipe 17 vertically slidably arranged inside the transmission pipe 16, and a blowing head 18 fixedly arranged at the free end of the elbow pipe 17. The blowing head 18 corresponds to the placing cage 6, and the blowing head 18 is fixedly connected to the bottom wall of the top cover 4.

[0036] The closing and spraying assembly 7 includes a pressure relief valve 11 fixedly arranged through the top plate 3, an air cylinder 28 vertically fixedly arranged on the bottom wall of the top plate 3, a piston 13 movably arranged in a fitting manner inside the air cylinder 28, a pressure relief valve 12 fixedly arranged on the upper wall of the piston 13, and a connecting column 14 vertically fixedly arranged at the lower end of the piston 13. The lower end of the connecting column 14 is fixedly connected to the upper wall of the top cover 4. The pressure relief valve 11 is connected to the inside of the air cylinder 28 in a penetrating manner. Through holes are formed in the piston 13 and the connecting column 14, and the through holes penetrate through the connecting column 14 and the top cover 4. The pressure relief valve 12 is connected to the through holes in a penetrating manner.

[0037] A sealing gasket 25 is fixedly arranged on the bottom wall of the top cover 4. The sealing gasket 25 corresponds to the outer edge of the top of the disinfection bucket 5. When the sealing gasket 25 contacts the upper edge of the disinfection bucket 5, the air spraying holes 24 correspond to the placing cage 6.

[0038] A vibration sensor 9 is fixedly arranged on the upper wall of the top cover 4. The model of the vibration sensor 9 is Honeywell IN-Z61. A central processor 10 is fixedly arranged on the upper wall of the bottom plate 1. The model of the central processor 10 is: PIC16F84A. The central processor 10 is electrically and controllably connected to the vibration sensor 9, and the central processor 10 is electrically and controllably connected to the air pump 15 and the electric heating tube 20.

[0039] The air output of the air spraying holes 24 is less than the amount of steam generated inside the water storage bucket 8, and the threshold value of the pressure relief valve 11 is less than the threshold value of the pressure relief valve 12.

[0040] During specific use, in the initial state, due to the pulling force of the reset tension spring 21, the top cover 4 is in a lifted state by itself. The placement cage 6 is located above the disinfection barrel 5. First, open the cage door, place the urological nursing instruments to be disinfected into the placement cage 6, then close the cage door of the placement cage 6, and then turn on the electric heating tube 20. The electric heating tube 20 heats the water in the water storage barrel 8. At this time, steam will be sprayed from the delivery pipe 23 and the air injection holes 24 into the disinfection barrel 5 to perform steam injection disinfection on the nursing instruments. Since the air output of the air injection holes 24 is less than the steam output, the air pressure in the water storage barrel 8 will gradually increase. When the air pressure in the water storage barrel 8 is greater than the threshold value of the first pressure relief valve 11, the steam in the water storage barrel 8 will enter the air cylinder 28 through the air pipe 19 and the first pressure relief valve 11. At this time, the steam in the air cylinder 28 will push the piston 13, the connecting column 14, and the top cover 4 downward. When the top cover 4 contacts the disinfection barrel 5, the piston 13 cannot move downward continuously. At this time, the air pressure in the air cylinder 28 gradually increases. When the air pressure in the air cylinder 28 is greater than the threshold value of the second pressure relief valve 12, the steam will pass through the through hole 29 through the piston 13, the connecting column 14, and the top cover 4, and finally enter the disinfection barrel 5 to spray steam on the nursing instruments in the placement cage 6 again. At this time, the air pressure in the disinfection barrel 5 gradually increases. When the air pressure in the disinfection barrel 5 increases to a certain extent, the top cover 4 will be pushed up. At this time, the vibration sensor 9 receives the vibration signal of the top cover 4 and transmits the vibration signal to the central processor 10. The central processor 10 issues an opening instruction to the air pump 15 and a closing instruction to the electric heating tube 20 at the same time;

[0041] Subsequently, the reset tension spring 21 drives the top cover 4 to slowly reset. Due to the pulling force of the reset tension spring 21, the gas in the air cylinder 28 will be squeezed by the piston 13. At this time, the gas in the air cylinder 28 will enter the air pipe 19, the water storage barrel 8, and the delivery pipe 23 in sequence through the first pressure relief valve 11, and finally slowly discharge from the air injection holes 24;

[0042] When the top cover 4 resets to the initial position, the horizontal position of the placement cage 6 corresponds to the hair dryer head 18, and at this time the air pump 15 is in an open state. The air pump 15 transmits the outside air into the elbow pipe 17, and then blows from the hair dryer head 18 to the placement cage 6, so as to air-dry the disinfected nursing instruments inside the placement cage 6. During this process, since the gas will pass through the inside of the water storage barrel 8 during the flow process, the remaining temperature of the hot water in the water storage barrel 8 is used to heat the air flow, effectively utilizing the heat energy. At the same time, the heated air flow can also improve the air-drying efficiency.

[0043] By changing the power of the electric heating tube 20, the amount of steam generated can be controlled, so that the steam disinfection time can be controlled. The greater the power of the electric heating tube 20, the more steam is generated, the more steam enters the disinfection barrel 5, and the shorter the disinfection time. Vice versa.

[0044] In summary, if those of ordinary skill in the art are inspired by this and, without departing from the gist of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
