Description

Technical Field

[0001] The invention relates to the technical field of clean operating rooms, and in particular to a self-cleaning control system for a clean operating room. Background Art

[0002] The clean operating room air purification system is to push out uniform vertical laminar airflow to the surroundings through multi-stage air filtration to remove suspended particles and microorganisms in the air to the greatest extent. The airflow flows from the operating area with high cleanliness to the area with low cleanliness, and takes away and discharges dust particles (dust particles) and bacteria in the airflow, thereby achieving air purification effect. Specification requirements: Hospital infection regulations: GB 50333-2013 Technical Specifications for Hospital Clean Operating Department Buildings, GB 15982-2012 Hospital Disinfection and Hygiene Standards, WST 592-2018 Hospital Infection Prevention and Control Evaluation Specification Requirements, Class I clean operating room has a minimum self-cleaning time of 10 minutes between operating rooms, Class II and Class III clean operating rooms have a minimum self-cleaning time of 20-30 minutes between operating rooms, and Class IV clean operating rooms have a minimum self-cleaning time of 30 minutes between operating rooms. The air purification effect of laminar flow operating rooms is directly related to the incidence of surgical infection.

[0003] The self-purification opening range of the clean operating room air purification system includes the operating room including the operating table. Opening requirements: After each operation, the pollution, auxiliary materials, and debris should be thoroughly removed under the normal operating conditions of the purification air conditioning system, and the floor should be mopped with disinfectant water, the walls and other surfaces should be scrubbed, and the air supply plate, return air outlet, shadowless lamp, etc. should be wiped and cleaned. After the cleaning and disinfection work is completed, turn on the forced exhaust fan to remove the indoor anesthetic waste gas and drugs. In addition, the purification air conditioning system should continue to operate until it is restored to the specified cleanliness level. In addition, when the air purification system is turned on, the operating room must be kept closed, and personnel are strictly prohibited from entering and exiting, and the door of the operating room is strictly prohibited from opening and closing.

[0004] Current situation: In the current use of clean operating rooms, the self-cleaning start and end times are manually controlled by circulating nurses and other relevant personnel. The operating room sensor door can still be sensed and opened during the self-cleaning period. Therefore, during the self-cleaning period of the operating room, there are methods such as hand-written self-cleaning time on paper pasted on the operating sensor door, manual hanging signs, or no warning signs. There are people entering by mistake, incorrect self-cleaning time control, operating room wall cleaning, and beautiful environment, which seriously affect the self-cleaning laminar flow effect of the clean operating room. The operating room is affected by the self-cleaning effect due to the failure to meet the self-cleaning time standard or the movement of people, which violates the hospital clean operating department building and other regulatory requirements, and there is an increase in the risk of surgical hospital infection.

[0031] The user interface module is responsible for interacting with the user and providing a graphical interface or command line interface for the control circuit; the user can input control instructions through this interface, such as turning on or off the load circuit.

[0032] The control circuit module is responsible for implementing the control instructions input by the user and generating corresponding control signals to control the circuit according to the instructions. For example, if the user inputs the instruction to turn on the load light, the module will generate the corresponding signal and send it to the circuit end through the communication interface.

[0033] The log recording module is responsible for recording important events and information during the software operation, such as user operations, system errors, circuit state changes, etc.; these log information is of great significance for troubleshooting, system optimization, etc.

[0034] Security management module, which is responsible for ensuring the safe operation of the software and preventing unauthorized access and operation. It may include functions such as user authentication, permission management, and data encryption.

[0035] The control circuit module is also connected to a display module, which includes a display light located outside the operating room induction door and linked to the induction door. In this embodiment, the display light can display the current operating room status through color and a lamp shell with information. When in the self-cleaning stage, a green light is used, and a prompt message of "self-cleaning in progress" is displayed, and a countdown is performed. When the self-cleaning time is over, the self-cleaning stage information is no longer displayed.

[0036] The circuit control module is provided with a plurality of circuit control units, and the circuit structure of a single circuit control unit is as follows: Figure 2The specific single circuit control unit is divided into two independent control circuits. The left circuit is used to realize the direct on-off control of the red light of the induction door "in operation", and the right circuit is used to realize the delayed on-off control of the green light of the induction door "self-cleaning min".

[0037] The circuit control unit includes positive and negative poles of the power supply, push button switches (SB1, SB2, SB3, SB4), relays (KA1, KA2), time relay KT, red light and green light.

[0038] The positive electrode of the power supply is electrically connected to the push button switch SB1, and the push button switch SB1 is connected in series with the push button switch SB2, the coil of the relay KA1, and the normally closed contact of the relay KA2 and then electrically connected to the negative electrode of the power supply to form a loop.

[0039] A red light is connected in parallel between the button switch SB1 and the negative pole of the power supply, and the red light is connected in series with a normally open contact of the relay KA1; after the button switch SB2 is closed, the relay KA1 is energized, and the light is connected in series with a normally open contact of the relay KA1, so that the red light is energized, and then the red word "In Surgery" appears on the sign light above the induction door; when the operation is over, the button switch SB2 is disconnected, and the relay KA1 returns to the state before power-on, so that the red light is turned off.

[0040] The button switch SB1 is normally closed, and the button switch SB2 is normally open.

[0041] Another normally open contact of relay KA1 is connected in parallel with push button switch SB2. When relay KA1 is energized, the normally open contact closes, keeping relay KA1 in the energized state.

[0042] The positive electrode of the power supply is connected to one end of the button switch SB3 through a wire. The button switch SB3 is connected in series with the button switch SB4, the coil of the relay KA2, the coil of the time relay KT, the normally closed contact of the relay KA1, and then connected to the negative electrode of the power supply to form a loop.

[0043] The time relay KT is connected in series with a green light, and the green light and the time relay KT are connected in parallel between the push button switch SB3 and the negative pole of the power supply; when the push button switch SB4 is closed, the time relay KT is energized, the normally open contact is closed, the green light is energized, and the green sign light above the induction door shows the words "self-purification min".

[0044] A normally open contact of relay KA2 is connected in parallel with push button switch SB4; when relay KA2 is energized, the normally open contact closes, causing time relay KT to start timing.

[0045] After the timing of the time relay KT ends, the green light is disconnected from the power supply to achieve delayed on-off control.

[0046] The present invention adds a "self-cleaning + time control countdown" link on the basis of the clean laminar flow equipment, links to control the display of the operating room sensor door, and installs a green light strip at the same time. The green "self-cleaning min" (set according to the level of the clean operating room) is prompted on the operating room sensor door, and counts down. When the time is up, the "self-cleaning" light automatically turns off, effectively controlling the self-cleaning time. At the same time, the "green" light implies a rest meaning, which is different from the red light during surgery. It can effectively realize the automatic control of the self-cleaning link of the operating room, reduce the workload of medical staff, and improve the accuracy of the self-cleaning time.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
