Description

Split cabinet type medical cleaning and sterilizing machine

Technical Field

The invention relates to the technical field of medical instruments, in particular to a split cabinet type medical cleaning and disinfecting machine.

Background

From the current medical cleaning equipment, a large-power and large-capacity industrial washing machine is generally adopted, in the cleaning process, the effect of removing dirt is achieved through high-strength friction force generated between clothes and clothes, between the clothes and a cylinder body, between the clothes and cleaning solution, and after the high-strength friction force acts on the clothes, high-strength pulling force or tension force can be naturally generated on materials and structures inside the clothes, so that if the medical protective clothing containing components such as non-woven fabrics, polyethylene, polypropylene, structural adhesive and the like is washed by the industrial washing machine, the medical protective clothing is completely damaged due to the fact that the medical protective clothing is weak in capability of bearing mechanical stirring external power and friction force, and the medical protective clothing cannot be applied at all.

As for the existing disinfection equipment after cleaning, the following three types can be classified according to different disinfection and sterilization modes:

1. physical type: the equipment mainly adopts modes of high temperature, high energy ray, illumination and the like to kill virus and bacteria, and comprises a hot air sterilizer, a heat radiation sterilizer, a high temperature steam sterilizer, a boiling sterilizer, a pressure steam sterilizer, an ultraviolet sterilizer, a high energy electron linear accelerator, cobalt-60 gamma source irradiation equipment and the like;

2. chemical type: the device mainly adopts a chemical agent mode to kill virus and bacteria, and comprises an ethylene oxide sterilizer, a formaldehyde sterilizer, an ozone sterilizer, a hydrogen peroxide sterilizer, a peracetic acid sterilizer, a glutaraldehyde sterilizer and the like;

3. mixing: the device is used for killing virus and bacteria in the same device by adopting physical and chemical modes, such as ultraviolet disinfection and ozone disinfection.

Although the above disinfection and sterilization equipment has different principles and structures, and different use cost, places and disinfection and sterilization duration, the disinfection and sterilization effect is often obvious, and particularly, the disinfection and sterilization equipment adopts physical and chemical modes such as far infrared rays, ultraviolet rays and ozone to kill in a synergistic manner, so that the disinfection and sterilization effect is often good, and the disinfection and sterilization equipment can completely achieve non-toxicity and sterility. Of course, the existing disinfection and sterilization equipment has certain limitations, which mainly appear in the following three aspects:

1. impairment of the properties: for medical protective clothing, latex medical articles and plastic tableware containing component components such as non-woven fabrics, polyethylene, polypropylene, structural adhesive and the like, and for clothes articles such as real silk, fur, pure wool and the like, the existing disinfection and sterilization equipment often causes adverse effects of high-temperature deformation, color change, oxidation and even aging decomposition;

2. harmful environment: chemical disinfectants adopted by the existing disinfection and sterilization equipment, such as ethylene oxide, formaldehyde, glutaraldehyde and the like, are usually healthy killers, are contacted at high concentration or low concentration for a long time, easily cause inflammatory lesions of upper respiratory tract, skin, eyes and nasal mucosa, and have symptoms of cough, dry throat, chest pain, mucosa secretion increase, fatigue, nausea and the like, most of the symptoms are listed as dangerous carcinogens, and the environmental pollution can be caused by direct discharge, so the existing health and environmental protection concept is not met;

3. and (4) limiting places: the sterilization of medical protective clothing and medical latex products containing non-woven fabrics, polyethylene, polypropylene and structural adhesive components is mainly carried out in modes of ethylene oxide, a high-energy electron linear accelerator, cobalt-60 gamma source irradiation and the like, but the sterilization equipment belongs to special equipment, is large in size, has strict and complicated required use environment and operation rules, is only suitable for industrial large-batch sterilization, and cannot be suitable for the sterilization of few-batch and sporadic articles in hospitals.

Due to the limitations of the existing medical cleaning and disinfecting equipment, the existing medical protective clothing is difficult to perform nondestructive cleaning and effective disinfection and sterilization, so that the medical protective clothing can only be used once and is difficult to be changed into the medical protective clothing which is repeatedly used for many times.

electromagnetic valves

41 and 42, and then is connected with a liquid inlet of a condensing agent pipe in the built-in condenser 43 through a liquid outlet of the built-in condenser electromagnetic valve 42, and a liquid outlet of the condensing agent pipe in the built-in condenser 43 is connected with a liquid inlet of the capillary tube 37; the liquid outlet of the capillary tube 37 is connected with the liquid inlet of the refrigerant tube in the evaporator 35, the liquid outlet of the refrigerant tube in the evaporator 35 is connected with the liquid inlet of the refrigerant circuit header pipe 38, and the liquid outlet of the refrigerant circuit header pipe 38 is connected with the refrigerant input tube of the external refrigeration compressor 29, so that a pipeline space for closed circulation of the refrigerant is formed; the external refrigeration compressor 29, the external condenser fan 30 and the external condenser 39 are integrated into a whole, and are arranged on an outdoor equipment platform of the cabinet 1 like a daily seen air conditioner host.

Refrigerant circulation: the refrigerant enters the evaporator 35 through the external compressor 29, the external condenser electromagnetic valve 26, the external condenser 39, the external condenser output pipe electromagnetic valve 27 and the capillary tube 37, circularly absorbs heat, returns to the external compressor 29 along the refrigerant loop main pipe 38, enters the evaporator 35 through the external condenser electromagnetic valve 26, the external condenser 39, the external condenser output pipe electromagnetic valve 27 and the capillary tube 37, absorbs heat again, returns to the external compressor 29 along the refrigerant loop main pipe 38, and the circulation is continuous. When the temperature sensor 40 detects that the temperature of the mixed gas input into the evaporator 35 is lower than the lower limit value (for example, 20 ℃) set by the system, in order to prevent the volatilization rate of 70% -75% ethanol disinfectant in the cabinet 1 from being reduced due to the excessively low temperature of the mixed gas, the system automatically closes the electromagnetic valve 26 of the external condenser and the electromagnetic valve 27 of the output pipe of the external condenser, stops the operation of the external condenser 39, simultaneously opens the

electromagnetic valves

41 and 42 of the internal condensers, and does not heat the mixed gas, and simultaneously, the electromagnetic valve 26 of the external condenser and the electromagnetic valve 27 of the output pipe of the external condenser are opened, and the external condenser 39 is started to carry out refrigeration and heat dissipation of the system.

The mixed gas in the cabinet 1 and the refrigerant in the external refrigeration compressor 29 are circulated continuously and repeatedly as described above, 70% -75% of ethanol in the mixed gas is condensed and liquefied and recovered continuously, the concentration of ethanol in the mixed gas in the cabinet 1 can be reduced to be very low, when the cleaning disinfectant sensor 44 detects that the concentration of ethanol in the circulated mixed gas is lower than a system set value (which should be far less than 3.3%, such as 1% and the like), the external refrigeration compressor 29 is turned off, the system stops the operation of condensing and recovering the mixed gas, and simultaneously, according to the anti-oxidation characteristics of the cleaned and disinfected clothes, the system automatically or manually selectively starts the ozone generator 45 to perform ozone synergistic disinfection on the cleaned and disinfected clothes, so as to eliminate peculiar smell.
