Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sterilization or disinfection of medical equipment, and in particular to a pressure steam cleaning and disinfecting device and an intelligent control system thereof. Background Art
[0002] With the rapid development of medical technology, there are more and more surgical instruments, and their functions and structures are becoming more and more complex. Reusable surgical instruments should be thoroughly cleaned and dried before packaging and sterilization. It is difficult to clean the instrument surface, joints, teeth and gaps of precision and complex surgical instruments. Surgical instruments after surgery often have residual non-water-soluble pollutants such as blood, body fluids, secretions and human tissues, which contain a large number of microorganisms. If they are not thoroughly cleaned for a long time, it is easy to form biofilms, which prevent the penetration of sterilization media or hinder the effective contact between microorganisms and steam, seriously affecting the sterilization effect, and increasing the risk of infection in patients when they are used again. At the same time, pollutants such as blood and body fluids remaining on the surface of surgical instruments will also corrode and damage surgical instruments. Once a biofilm is formed, even if correct and effective disinfection and sterilization are carried out, pathogenic microorganisms will still survive. Studies have shown that 50% of hospital infections are related to biofilms on medical devices. Effective sterilization of surgical instruments is one of the key factors to prevent incision infection and an important measure to control hospital infections. Correct and high-quality cleaning, disinfection and drying of surgical instruments are the key links and prerequisites for successful instrument sterilization. The use of fully automatic cleaning and disinfecting equipment can not only greatly improve the cleaning quality, drying quality and work efficiency, facilitate standardized management and quality monitoring, but also reduce environmental pollution and avoid occupational exposure.
[0003] Prior art 1, application number: CN202411898875.8 discloses a sterilizer and pipeline control system for recovering heat energy and draining water at low temperature, including a cabin, a pure water tank and a waste water tank, the pure water tank is arranged at the upper end of the cabin, the waste water tank is arranged at the lower end of the cabin, two peristaltic pumps are connected to one side of the cabin, the two peristaltic pumps are in parallel state, the two peristaltic pumps are connected to two liquid level floats, a pressure transmitter is arranged at the upper end of the cabin, the pressure transmitter is connected to a circulation pump, the circulation pump is connected to the lower end of the cabin, an air heating box is arranged between the pressure transmitter and the circulation pump, the air heating box is connected to a high-efficiency filter, and a second wind pressure switch is arranged between the air heating box and the high-efficiency filter. Although the integrated design recovers the heat energy of the water after disinfection and realizes low-temperature drainage at the same time; however, its design focuses on heat recovery and drainage temperature control, does not integrate the quality perception-dose calculation closed-loop system, and cannot dynamically adapt to the chemical reagent requirements of different equipment loads; it can realize heat recovery and low-temperature drainage, but lacks precise dosage control of cleaning agents / disinfectants and programmed cleaning process management.
[0004] Prior art 2, application number: CN202111006108.8 discloses a disinfection device for equipment used in a hospital nursing department, including a disinfection box, a heat-insulating chassis is detachably connected to the middle part of the disinfection box, a disinfector is detachably connected to the outer surface of the upper end of the disinfection box, a drain outlet is detachably connected to the outer surface of one side of the disinfection box, a mobile frame is fixedly connected to the outer surface of the lower end of the disinfection box, a disinfection water tank is detachably connected to the outer surface of the rear end of the disinfection box, and a slide is fixedly connected to the outer surface of the front end of the disinfection box. Although the scope of application of the equipment has been increased and the limitations of the use of the disinfection box have been reduced; this setting facilitates steam disinfection of nursing appliances, killing bacteria on the nursing appliances by high-temperature steam; this setting facilitates secondary double sterilization and disinfection of nursing appliances, with obvious disinfection effect, which is beneficial for subsequent use; this setting facilitates cleaning and disinfection of nursing appliances, and the disinfection is comprehensive and the disinfection effect is better; however, it relies on a single steam sterilization mode, lacks a multi-step cleaning and disinfection process with programmed control, and has no drying energy recovery mechanism, and has low energy efficiency; the function is limited to high-temperature steam disinfection, and a phased (initial wash, rinsing, and final treatment) automated cleaning and disinfection closed loop has not been achieved.
[0005] Prior art three, application number: CN202110281856.0 discloses an automatic adjustment switching steam sterilizer, including a control housing, a mounting cavity with an opening facing outward, a heating furnace fixedly installed between the upper and lower walls of the mounting cavity, a heating cavity provided in the heating furnace, the heating cavity can store water, a moving cavity provided on the lower side of the mounting cavity, and an air cavity provided on the upper side thereof, and a lifting column sliding up and down in the inner wall between the air cavity and the moving cavity. Although it can not only steam clean and disinfect the inside of the bottle, and steam wrap and disinfect the periphery of the bottle, but also form a closed space through transmission control of the heating cavity, so that the internal steam boost temperature is increased, thereby generating superheated steam, so that the superheated steam can dry and disinfect the bottle after cleaning and disinfection again, it is convenient to use and has a good automatic adjustment effect; however, the design does not cover the instrument quality detection and dosage calculation functions, and cannot adapt to the cleaning agent requirements of instruments of different specifications; and there is no circulation flushing function, and the cleaning effect is limited; it only targets steam sterilization and drying of specific containers (bottles), and does not solve the cleaning adaptability problem of medical instruments with complex structures (such as tubular cavity instruments).

[0052] Example 1: Figure 1 As shown, an embodiment of the present invention provides a pressure steam cleaning and disinfecting device, comprising:
[0053] The dosage calculation component is responsible for obtaining the mass of the equipment to be cleaned and disinfected, calculating the dosage of the cleaning agent and disinfectant to be added according to the mass, and delivering the dosage to the controller, which controls the delivery of the cleaning agent and disinfectant to the actuator; placing the equipment to be cleaned and disinfected into the cleaning and disinfection area through the door operating device;
[0054] The program control component is responsible for detecting whether the door operating device is completely closed. After it is completely closed, the automatic cleaning and disinfection control program pre-stored in the controller is called up, and the actuators corresponding to the softened water, cleaning agent and disinfectant are turned on under the control of the automatic cleaning and disinfection control program to complete the initial washing, cleaning agent washing, rinsing, disinfection and final rinsing of the equipment to be cleaned and disinfected;
[0055] The drying and recovery component is responsible for drying the instruments to be cleaned and disinfected after the final rinse of the automatic cleaning and disinfection control program is completed; at the same time, it recovers the heat energy during the automatic cleaning and disinfection control program to heat the softened water; after the drying is completed, the controller controls the door operating device to take out the cleaning and disinfection instruments that have been cleaned and disinfected.
[0056] The working principle and beneficial effects of the above technical solution are as follows: the dosage calculation component of this embodiment obtains the mass of the instrument to be cleaned and disinfected, calculates the dosage of the cleaning agent and disinfectant to be added according to the mass, and delivers the dosage to the controller, which controls the delivery of the cleaning agent and disinfectant to the actuator; the instrument to be cleaned and disinfected is placed in the cleaning and disinfection area through the door operating device; the program control component detects whether the door operating device is completely closed, and after it is completely closed, calls the automatic cleaning and disinfection control program pre-stored in the controller, and starts the actuators corresponding to softened water, cleaning agent and disinfectant under the control of the automatic cleaning and disinfection control program to complete the initial washing, cleaning agent washing, rinsing, disinfection and final rinsing of the instrument to be cleaned and disinfected; after the final rinsing of the automatic cleaning and disinfection control program of the drying and recovery component is completed, the instrument to be cleaned and disinfected is dried; at the same time, the heat energy in the process of the automatic cleaning and disinfection control program is recovered to heat the softened water; after the drying is completed, the controller controls the door operating device to take out the cleaning and disinfection instrument that has been cleaned and disinfected. The dosage calculation component of the above scheme determines the mass of the instrument (mainly medical instruments, but also surgical instruments) by weighing, providing a data basis for the accurate measurement of cleaning agents and disinfectants; automatically calculates the amount of chemical reagents required to ensure that the cleaning and disinfection effects meet the expected effects; transmits the calculation results to the controller, which drives the cleaning agent and disinfectant to be added to the cleaning process in proportion; the closed management of the door operating device ensures that the instrument is in a closed state before entering the cleaning area to avoid external contamination or medium leakage, thereby improving the safety of the operation. The program control component detects whether the door is completely closed to ensure that the sterilization operation is carried out in a closed environment to avoid steam leakage or external contamination; calls the pre-programmed cleaning and disinfection process, including initial washing (softened water pre-washing), cleaning agent washing (chemical decontamination), rinsing (removal of residual chemicals), disinfection (high temperature or chemical sterilization) and final rinsing (final cleaning guarantee), to ensure compliance with the cleaning and disinfection standards of medical devices; accurately adjusts parameters such as softened water supply, cleaning agent injection and steam pressure according to the program stage to ensure that the cleaning and sterilization requirements at different stages are accurately controlled. After the final rinse, the drying and recovery component uses high-temperature airflow to dry the instruments to eliminate residual moisture and prevent secondary contamination or instrument corrosion; it recovers waste heat energy generated during cleaning and high-temperature disinfection and uses it to preheat softened water, reducing energy consumption and improving operating efficiency; after the drying stage is completed, the controller controls the door operating device to automatically open or unlock, allowing the user to safely remove the sterilized instruments.
[0057] In this embodiment, the pressure steam cleaning and disinfection device is mainly composed of a cleaning system, a door system, intelligent metering of cleaning agents and disinfectants, a drying system, a control system and a heat recovery condensation system; the cleaning system adopts dynamic cleaning, which has the advantages of small friction loss, large suction range, large water flow and pressure balance system, and can achieve a good cleaning effect with a small amount of water and cleaning agents. The water flow docking system of the cleaning rack uses water pressure to dock the cylindrical interface in the equipment with the cleaning rack interface to maintain the best water control state for the cleaning rack. The door system of the cleaning and disinfection device mainly adopts two independent and vertically opened automatic doors to effectively isolate the two areas. The operation and closing device of the door system are controlled by software and detectors; the water inlet pipeline cycle program is short, and a softened water preheating device or a steam generator can be realized, which can shorten the program cycle time. Intelligent metering of cleaning agents and disinfectants is to more accurately determine the required additive dosage. The drying system uses two high-performance brushless dryers. On the one hand, the hot dry air is guided through the water supply line and the injection system, and on the other hand, it enters the cleaning cabin through the direct injection port. The gas diversion can quickly dry the cleaned items. The control system mainly includes three parts: display, error system analysis and interface. ① The display adopts new microprocessor control technology, and 12 custom programs can be input. The pre-edited programs in the program library can be used as custom programs; ② The error analysis control system is a diagnostic system. Since most of the test programs are automatically run periodically, the system is designed to detect potential errors in a timely manner. The input signals will be monitored and displayed visually and auditorily when they deviate from the established standard values; ③ The interface network operation and batch file processing are connected through RS 485. The use of data processing system 8500 can make the processing more specific. The batch files are archived and recorded in the SQL database. The system can manage and query sterilized items. The communication module is used for service, testing, maintenance, recording and monitoring, data statistics, remote control, and automatic operation. The advantage of the heat recovery condensation system is that the water used for cooling in the exhaust condensation cleaning process can be recycled, and the recovered heat energy can be used for heating softened water. By preheating softened water, the program cycle is shortened.
[0058] The cleaning and disinfection machine of this embodiment is essentially a device that uses cleaning agents and disinfectants to automatically control programs to complete the initial washing, cleaning agent cleaning, rinsing, disinfection, and final rinsing of instruments to replace traditional manual cleaning and disinfection of instruments. The instruments are immersed in cleaning liquid or disinfectant, and there is also a pressurized circulation device to pressurize the cleaning liquid or disinfectant to circulate and flush the inner and outer walls of the instrument pipeline. Finally, the inner wall of the instrument pipeline is dried by a gas drying device to complete the cleaning and disinfection of the instrument.

[0092] In summary, this embodiment transforms the traditional empirical disinfection scheme into an accurate dosage output system based on three-dimensional topological modeling and parametric analysis through a progressive analysis chain of instrument quality, structural characteristics, contamination characteristics and dosage requirements. It not only standardizes the cleaning and disinfection process, but also optimizes the efficiency of chemical use through parameter association. Each module forms a complete closed-loop environmentally-friendly calculation system from physical data acquisition to chemical dosage output.
