Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a split cabinet-type medical cleaning and disinfecting machine. Background Art

[0002] From the existing medical cleaning equipment, high-power, large-capacity industrial washing machines are generally used. During the cleaning process, the high-intensity friction between clothes, clothes and the cylinder, clothes and detergent is used to remove dirt. When the high-intensity friction acts on the clothes, it will naturally produce high-intensity pulling or tension on the materials and structures inside the clothes. Therefore, if an industrial washing machine is used to wash medical protective clothing containing components such as non-woven fabrics, polyethylene, polypropylene, and structural adhesives, it will be completely destructive and cannot be used at all because its ability to withstand the external force and friction of mechanical stirring is very weak.

[0003] As for the existing disinfection equipment after cleaning, it can be divided into the following three types according to the different methods of disinfection and sterilization:

[0004] 1. Physical type: mainly equipment that uses high temperature, high-energy rays and light to kill viruses and bacteria, including hot air sterilizers, thermal radiation sterilizers, high-temperature steam sterilizers, boiling sterilizers, pressure steam sterilizers, ultraviolet sterilizers, high-energy electron linear accelerators, cobalt-60 gamma source irradiation equipment, etc.;

[0005] 2. Chemical type: mainly uses chemical agents to kill viruses and bacteria, including ethylene oxide sterilizer, formaldehyde sterilizer, ozone sterilizer, hydrogen peroxide sterilizer, peracetic acid sterilizer, glutaraldehyde sterilizer, etc.

[0006] 3. Hybrid type: It is a device that uses physical and chemical methods to kill viruses and bacteria in the same device. Common ones include ultraviolet disinfection + ozone disinfection.

[0007] Although the above disinfection and sterilization equipment has different principles and structures, and the cost, location and duration of use are different, the disinfection and sterilization effect is often obvious, especially when physical and chemical methods such as far infrared, ultraviolet, and ozone are used to disinfect together, the disinfection and sterilization effect is often very good, and it can completely achieve non-toxic and sterile. Of course, the existing disinfection and sterilization equipment also has certain limitations, which are mainly reflected in the following three aspects:

[0008] 1. Damage to performance: For medical protective clothing, latex medical products and plastic tableware containing components such as non-woven fabrics, polyethylene, polypropylene, structural adhesives, as well as silk, fur, pure wool and other clothing products, existing disinfection and sterilization equipment often causes adverse consequences such as high-temperature deformation, discoloration, oxidation and even aging and decomposition;

[0009] 2. Harmful environment: Chemical disinfectants used in existing disinfection and sterilization equipment, such as ethylene oxide, formaldehyde, glutaraldehyde, etc., are often health killers. High concentrations or long-term low-concentration exposure can easily cause inflammation and lesions in the upper respiratory tract, skin, eyes, and nasal mucosa, and symptoms such as coughing, dry throat, chest pain, increased mucosal secretions, fatigue, nausea, etc. Most of them are listed as dangerous carcinogens, and direct discharge will cause environmental pollution, which is not in line with the current health and environmental protection concept;

[0010] 3. Restricted places: For factory disinfection of medical protective clothing and latex medical products containing non-woven fabrics, polyethylene, polypropylene, and structural adhesive components, ethylene oxide, high-energy electron linear accelerators, cobalt-60 gamma source irradiation, etc. are currently the main methods used. However, the above-mentioned disinfection equipment are all special equipment. They are not only large in size, but also require strict and complex use environments and operating procedures. They are only suitable for large-scale factory disinfection, and cannot be used for disinfection of small batches or sporadic items in hospitals.

[0011] It is precisely because of the above-mentioned limitations of existing medical cleaning and disinfection equipment that it is difficult to carry out non-destructive cleaning and effective disinfection and sterilization of medical protective clothing after use, so that medical protective clothing can only be used once, and it is difficult to convert it into medical protective clothing that can be used repeatedly. Summary of the invention

[0012] In order to overcome the shortcomings of existing medical cleaning and disinfection equipment, the present invention provides an external refrigeration compressor unit, which can be used as a cabinet machine for non-destructive cleaning and effective disinfection and sterilization of clothes including medical protective clothing at normal temperature and pressure (25±5℃, 1 atmosphere). The basic working principle of the machine is: the cleaning and disinfection liquid is sprayed on the clothes to be cleaned and disinfected, or pumped into an ultrasonic cleaning tank containing the items to be cleaned and disinfected, and after continuous or intermittent atomization spray cleaning and disinfection, the cleaning and disinfection liquid is pumped back to the storage tank by a recovery pump, and then the mixed gas in the cleaning and disinfection machine is circulated, condensed and liquefied, and the cleaning and disinfection liquid in the mixed gas is recovered. After continuous condensation, liquefaction and recovery, until the concentration of the cleaning and disinfection liquid in the mixed gas is equal to the value set by the system, the system automatically or manually selects to start the ozone generator according to the characteristics of the cleaning items, and uses ozone to carry out cooperative disinfection for a certain period of time on the clothes to remove odors. After the cleaning and disinfection operation time automatically set or manually set by the system is completed, the purified air is finally sucked into the cabinet through the mixed gas and ozone residual exhaust system, and the cleaning and disinfection liquid and ozone residue in the mixed gas in the cabinet are circulated and diluted, and then discharged outside the machine until the cleaning and disinfection liquid and ozone residue in the cabinet are reduced to near zero, that is, all cleaning and disinfection operations are completed.

[0013] The medical cleaning and disinfection work completed by the present invention is a weak power operation under normal temperature and pressure, without mechanical strong rolling stirring and high temperature and high pressure. This can achieve non-destructive cleaning for items with low force strength and high temperature intolerance, such as medical protective clothing containing components such as non-woven fabrics, polyethylene, polypropylene, structural adhesives, latex medical items, etc., while completing efficient and thorough disinfection and sterilization operations. In addition, the use of non-toxic and harmless cleaning and disinfection liquid and ozone that can be decomposed into oxygen in a short time for coordinated disinfection can achieve non-toxic and low-residue emissions, no harm to human health, no pollution to the use environment, and can be conveniently installed in the doctor and nurse dressing room of the hospital and other application places as needed.

[0014] In order to realize the above functional characteristics, the technical solution adopted by the present invention is: the cleaning and disinfection machine is split, the indoor main unit part is cabinet-shaped, and is in a sealed working state at normal temperature and pressure, and the outdoor extension part is a refrigeration compressor unit placed on the outdoor equipment platform. The cleaning and disinfection machine is integrated with atomization spray and ultrasonic cleaning and disinfection system, mixed gas circulation condensation recovery and ozone disinfection system, mixed gas and ozone residual emission system and intelligent control circuit system, which can realize automatic, complete and controllable cleaning, disinfection and sterilization work. The specific working process is as follows.

[0015] First, start the atomizing spray and ultrasonic cleaning and disinfection system: use a spray pressure pump to atomize and spray the cleaning and disinfection liquid onto the clothes or pump it into the ultrasonic cleaning and disinfection tank, and set the corresponding continuous or interval operation time to ensure the cleaning and disinfection effect; when the spray liquid accumulation container is full or the ultrasonic cleaning and disinfection time expires, the system automatically starts the recovery pump to draw the accumulated cleaning and disinfection liquid or the used cleaning and disinfection liquid in the ultrasonic tank back to the storage tank, completing the first operation process of the cleaning and disinfection machine.

[0016] The second step is to start the mixed gas circulation condensation recovery and ozone disinfection system: after completing the first operation process, the cabinet is filled with a high concentration of cleaning and disinfection liquid mixed gas, and there are also a lot of liquid cleaning and disinfection liquid attached to the inside and surface of the clothes being cleaned and disinfected. For this reason, the fan and external refrigeration compressor unit are started to circulate and condense the mixed gas in the cabinet continuously, so that the mixed gas flows through the evaporator in a low-temperature state. The cleaning and disinfection liquid vapor in the mixed gas is naturally condensed and liquefied due to the cold, and then gathered through the collecting pipe and flowed into the cleaning and disinfection liquid storage tank. This cycle is repeated continuously until the cleaning and disinfection liquid content in the mixed gas is lower than the system setting value, and the external refrigeration compressor unit stops running, thereby realizing the maximum recovery of the cleaning and disinfection liquid, and the clothes being cleaned and disinfected are also dried at the same time. After that, according to the antioxidant properties of the cleaning items, the system automatically or manually chooses to start the ozone generator, and uses ozone to disinfect and sterilize the clothes for a certain period of time to remove odors.

[0017] Finally, start the mixed gas and ozone residual emission system: After the above operation process is completed, the mixed gas in the cleaning and disinfection machine and the clothes are often mixed with trace amounts of cleaning and disinfection liquid and ozone residues. In order to eliminate the residues, the system is set to automatically start the fan to directly suck the purified external air into the cleaning and disinfection machine, and then discharge it outside the machine after internal circulation and dilution. The extremely small amount of cleaning and disinfection liquid and ozone contained in the exhaust gas is harmless to the human body and will not cause pollution to the environment.

[0018] Intelligent control circuit system: The system consists of a power module, an input module, a detection module, a data processing module and a control circuit module. The signal transmission relationship between the circuit modules is as follows: the power module circuit provides voltage stabilization, rectification and overload protection for the whole machine circuit; the input module circuit inputs the corresponding data signal to the microprocessor, and the microprocessor also feeds back the corresponding data signal and displays it on the touch LCD screen; the detection module circuit transmits the real-time data signal of each detection sensor to the microprocessor; the microprocessor in the data processing module circuit is the core component of the whole machine intelligent control circuit, responsible for the programmed data calculation and control of the whole machine; the control circuit module circuit directly drives the corresponding electrical components of the atomizing spray and ultrasonic cleaning and disinfection system, the mixed gas circulation condensation recovery and ozone disinfection system, the mixed gas ozone residual emission system and other auxiliary electrical components to open, close, run, stop and other actions according to the command signal sent by the microprocessor, and at the same time feeds back the real-time voltage, current and other data signals of each running electrical component to the microprocessor, providing a basis for the microprocessor to monitor the operation of the whole machine and adjust the parameters in real time.

[0019] Compared with the prior art equipment, the beneficial effects of the present invention are: it makes up for the shortcomings of the existing medical cleaning and disinfection equipment, fills the gap in medical weak-power cleaning and disinfection equipment at normal temperature and pressure, and can perform non-destructive cleaning and disinfection on clothing with low force strength and intolerant to high temperatures, including daily cleaning and disinfection of medical protective clothing containing non-woven fabrics, polyethylene, polypropylene, and structural adhesive components, latex medical supplies, and plastic tableware, etc., providing a simple, efficient, low-cost, healthy and environmentally friendly cleaning and disinfection equipment for repeated use of medical protective clothing, reducing the cost of using medical protective clothing, and reducing medical waste.

This diagram is actually Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The summary integration diagram contains Figure 3 The atomizing spray and ultrasonic cleaning and disinfection system shown, Figure 4 The mixed gas circulation condensation recovery and ozone disinfection system shown, Figure 5 The mixed gas and ozone residual emission system shown, Figure 7 The schematic diagram of the built-in movable spray cleaning and disinfection hanging hanger is shown in FIG. Figure 8 The planar structural diagram of the atomizing spray hole and the air jet hole shows the structural relationship and operating principle of the above-mentioned functional systems from the perspective of system assembly.

[0036] Figure 3The schematic diagram of the atomizing spray and ultrasonic cleaning and disinfection system is described in the order in which the cleaning and disinfection liquid flows through each component or space (the flow direction is shown by the arrow in the figure). The components of the system and their connection relationship are as follows: the discharge port of the cleaning and disinfection liquid storage tank 8 is connected to the infusion main pipe 9, the infusion main pipe 9 is connected to the liquid inlet of the spray pressure pump 10, the liquid outlet of the spray pressure pump 10 is connected to the liquid inlet of the infusion solenoid valve 11, the liquid outlet of the infusion solenoid valve 11 is connected to the liquid inlet of each atomizing spray branch pipe 12, the liquid outlet of the atomizing spray branch pipe 12 is connected to each atomizing spray hole 13 and the hanging hanger 14 are connected to each divided space in the cabinet 1, and the other part of the atomizing spray The liquid outlet of the shower branch pipe 12 is connected to the ultrasonic cleaning tank input pipe 15, which is communicated with the ultrasonic generator cleaning tank 16. The discharge pipe 17 is connected to the accumulated liquid discharge and mixed gas output hole 18. The accumulated liquid discharge and mixed gas output hole 18 is connected to the recovery pipe 19 and then to the liquid inlet of the recovery solenoid valve 20. The liquid outlet of the recovery solenoid valve 20 is connected to the recovery main pipe 21, and is connected to the liquid inlet of the filter 22 through the recovery main pipe 21. The liquid outlet of the filter 22 is connected to the liquid inlet of the recovery pump 23. The liquid outlet of the recovery pump 23 is connected to the recovery input port of the cleaning and disinfecting liquid storage tank 8. The cleaning and disinfecting liquid storage tank liquid level and concentration float sensor 24 floats on the liquid surface of the cleaning and disinfecting liquid storage tank 8.

[0037] The system is the first operating system started and operated by the present invention, and its operating process is as follows: through the touch LCD display screen 3 on the cabinet 1, the spray pressure pump 10 and the infusion solenoid valve 11 are automatically or manually started, and the 70%-75% medical ethanol disinfectant in the cleaning and disinfection liquid storage tank 8 enters each atomizing spray branch pipe 12 or the ultrasonic cleaning tank input pipe 15 in the cabinet 1 through the infusion main pipe 9, the spray pressure pump 10 and the infusion solenoid valve 11. Under the action of the pump pressure, the atomizing spray hole 13 or the ultrasonic cleaning tank input pipe 15 starts atomizing spray or inputs ethanol disinfectant to clean and disinfect the clothes in the hanging hanger 14 or the ultrasonic generator cleaning tank 16. After the set atomizing spray cleaning and disinfection time is reached, the spray pressure pump 10 and the infusion solenoid valve 11 are closed, and the ethanol disinfectant is no longer transported into the cabinet 1. During the setting of continuous or intermittent atomization spraying and ultrasonic cleaning and disinfection, and after the cleaning and disinfection time is up, the recovery solenoid valve 20 and the recovery pump 23 are turned on and run, and the ethanol effluent and the ethanol disinfectant in the ultrasonic disinfection tank are automatically pumped back to the cleaning and disinfection liquid storage tank 8 through the discharge pipe 17, the effluent discharge and mixed gas output hole 18, the recovery pipe 19, the recovery solenoid valve 20, the recovery main pipe 21, the filter 22, and the recovery pump 23. When the ethanol accumulated residual liquid in the cabinet 1 or the ethanol disinfectant in the ultrasonic generator cleaning and disinfection tank 16 is completely pumped back to the cleaning and disinfection liquid storage tank 8, the recovery solenoid valve 20 is closed and the recovery pump 23 is shut down. During this period, the liquid level and concentration change information of the cleaning and disinfection liquid storage tank 8 is output through the liquid level and concentration sensor 24, and the first operation process of atomization spraying and ultrasonic cleaning and disinfection is completed.

[0038] Figure 4 The mixed gas circulation condensation recovery and ozone disinfection system shown includes a mixed gas ozone circulation subsystem and a refrigerant circulation subsystem.

[0039] Mixed gas ozone circulation subsystem: The components and their connection relationship of the mixed gas and ozone circulation subsystem are as follows: the air outlet of the main gas transmission solenoid valve 25 is connected to the air inlet of the evaporator 35, a temperature sensor 40 is installed in the evaporator 35, the air outlet of the evaporator 35 is connected to the air inlet of the fan 28, the condensate collection output port of the evaporator 35 is connected to the liquid inlet of the cleaning and disinfection liquid recovery pipe 36, the liquid outlet of the cleaning and disinfection liquid recovery pipe 36 is connected to the cleaning and disinfection liquid storage tank 8, and the fan 28 is connected to the cleaning and disinfection liquid storage tank 8. The air outlet of the machine 28 is equipped with a cleaning and disinfecting liquid sensor 44, and is connected to the air inlet of the ozone generator 45. The air outlet of the ozone generator 45 is connected to the gas main pipe 31. The gas main pipe 31 is provided with a gas input hole 32 leading to the internal space of the cabinet 1. At the same time, the gas main pipe 31 is provided with multiple branches connected to the jet hole 33 and the hanging hanger 14. The accumulated liquid discharge and mixed gas output hole 18 is connected to the air inlet of the mixed gas circuit main pipe 34. The air outlet of the mixed gas circuit main pipe 34 is connected to the air inlet of the gas main solenoid valve 25, thereby forming a pipeline space for the closed circulation of mixed gas and ozone.

[0040] Refrigerant circulation subsystem: The components of the refrigerant circulation subsystem and their connection relationship are described in the order in which the refrigerant flows through each component (as shown by the flow arrows in the figure): the refrigerant in the external refrigeration compressor 29 is divided into two output pipes, one of which is the refrigerant output pipe in the external refrigeration compressor 29 connected to the liquid inlet of the external condenser solenoid valve 26, the liquid outlet of the external condenser solenoid valve 26 is connected to the liquid inlet of the condenser pipe in the external condenser 39, the liquid outlet of the condenser pipe in the external condenser 39 is connected to the liquid inlet of the external condenser output pipe solenoid valve 27, and the liquid outlet of the external condenser output pipe solenoid valve 27 is connected to the liquid inlet of the capillary tube 37; the other is the refrigerant output pipe in the external refrigeration compressor 29 connected to the built-in condenser solenoid valve A 41 and the built-in condenser solenoid valve B 42, and then communicates with each other through the built-in condenser solenoid valve B The liquid outlet of 42 is connected to the liquid inlet of the condenser pipe in the built-in condenser 43, and the liquid outlet of the condenser pipe in the built-in condenser 43 is connected to the liquid inlet of the capillary tube 37; the liquid outlet of the capillary tube 37 is connected to the liquid inlet of the refrigerant pipe in the evaporator 35, and the liquid outlet of the refrigerant pipe in the evaporator 35 is connected to the liquid inlet of the refrigerant circuit main pipe 38, and the liquid outlet of the refrigerant circuit main pipe 38 is connected to the refrigerant input pipe of the external refrigeration compressor 29, thereby forming a pipeline space for closed circulation of refrigerant; the external refrigeration compressor 29, the external condenser fan 30 and the external condenser 39 are integrated into one, just like the air conditioner host seen in daily life, and are placed on the outdoor equipment platform of the cabinet 1. The inner wall and outer wall of the cabinet 1 are made of metal thin plates with good thermal conductivity, and the inner and outer walls are isolated by thermal insulation materials. The built-in condenser 43 is directly close to the outer side of the metal thin plate on the inner wall of the cabinet 1.

[0041] The operating process of the system is:

[0042] Condensation circulation of mixed gas in cabinet 1 and coordinated disinfection with ozone: when the recovery pump 23 of the first operation process stops running, the main gas transmission solenoid valve 25, the external condenser solenoid valve 26 and the external condenser output pipe solenoid valve 27 in cabinet 1 are opened, and at the same time, the fan 28, the external refrigeration compressor 29 and the external condenser fan 30 are started and run. Under the pressure of the fan 28, the mixed gas in cabinet 1 is input into each divided space in cabinet 1 along the gas transmission main pipe 31 through the gas input hole 32, the jet hole 33 and the hanging hanger 14, and then discharged through the accumulated liquid discharge and the mixed gas output hole 18, and transported to the evaporator 35 along the mixed gas circuit main pipe 34. Because the mixed gas encounters resistance and is cooled, the ethanol gas and water vapor in the mixed gas are condensed, liquefied and gathered, and pass through The cleaning and disinfectant recovery pipe 36 flows back into the cleaning and disinfectant storage tank 8, thereby realizing the post-use recovery of part of the 70%-75% ethanol disinfectant; after condensing and recovering part of the 70%-75% ethanol disinfectant, the ethanol and water vapor content of the mixed gas is greatly reduced, and under the action of the fan 28, it is again input into each space in the cabinet 1 through the gas main pipe 31, and the mixed gas therein is diluted again, and the mixed gas carrying part of the 70%-75% ethanol disinfectant remaining therein is discharged again through each accumulated liquid discharge and mixed gas output hole 18, and is transported to the evaporator 35 along the mixed gas circuit main pipe 34, and part of the 70%-75% ethanol disinfectant therein is condensed and recovered again, and then enters the next cycle, and the cycle is repeated continuously.

[0043] Refrigerant cycle: The refrigerant enters the evaporator 35 through the external compressor 29, the external condenser solenoid valve 26, the external condenser 39, the external condenser output pipe solenoid valve 27, and the capillary tube 37. After absorbing heat through the cycle, it returns to the external compressor 29 along the refrigerant circuit main pipe 38, and then enters the evaporator 35 through the external condenser solenoid valve 26, the external condenser 39, the external condenser output pipe solenoid valve 27, and the capillary tube 37. After absorbing heat again, it returns to the external compressor 29 along the refrigerant circuit main pipe 38, and the cycle repeats continuously. When the temperature sensor 40 detects that the temperature of the mixed gas input to the evaporator 35 is lower than the lower limit value set by the system (such as 20°C), in order to prevent the mixed gas temperature from being too low, causing the volatilization rate of the 70%-75% ethanol disinfectant in the cabinet 1 to decrease, the system automatically closes the external condenser solenoid valve 26 and the external condenser output pipe solenoid valve 27, stops the operation of the external condenser 39, and opens the built-in condenser solenoid valve A 41 and the built-in condenser solenoid valve B 42 at the same time, starts the built-in condenser 43 in the cabinet 1, and heats up the mixed gas temperature in the cabinet 1 through the heat released by the built-in condenser 43 and the heat generated by the operation of the fan 28. When the mixed gas temperature flowing through the evaporator 35 reaches the upper limit value set by the system (such as 30°C), the system automatically closes the built-in condenser solenoid valve A 41 and the built-in condenser solenoid valve B 42, the mixed gas in the cabinet 1 is no longer heated by the built-in condenser 43, and the external condenser solenoid valve 26 and the external condenser output pipe solenoid valve 27 are opened at the same time, and the external condenser 39 is enabled to perform system cooling and heat dissipation.

[0044] The inner and outer walls of the cabinet 1 are made of metal materials with good thermal conductivity, such as stainless steel thin plates, and the inner and outer walls are isolated with insulating materials such as polyurethane rigid foam. The built-in condenser 43 is directly attached to the outer side of the inner wall steel plate of the cabinet 1 to enhance the heat conduction into the cabinet 1 through the inner wall stainless steel plate, ensuring that the temperature of the mixed gas during the circulating condensation process is always within the set normal temperature range.

[0045] As described above, the mixed gas in the cabinet 1 and the refrigerant in the external refrigeration compressor 29 are circulated over and over again, and the 70%-75% ethanol in the mixed gas is continuously condensed, liquefied and recovered, and the ethanol concentration of the mixed gas in the cabinet 1 can be reduced to a very low level. When the cleaning and disinfecting liquid sensor 44 detects that the ethanol concentration of the circulating mixed gas is lower than the system setting value (should be much less than 3.3%, such as 1%), the external refrigeration compressor 29 is turned off, and the system stops the mixed gas condensation and recovery operation. At the same time, according to the antioxidant characteristics of the clothes to be cleaned and disinfected, the system automatically or manually selectively starts the ozone generator 45 to perform ozone coordinated disinfection on the cleaned and disinfected clothes to eliminate odors. When the ozone disinfection time automatically or manually set by the system expires, the system automatically turns off the ozone generator 45, and the mixed gas circulation condensation recovery and ozone disinfection operations are completed.
