[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The present invention provides a technical solution: a self-disinfecting bedside table for use in a ward and remotely controlled by a hospital HIS system, comprising a bedside table body 1, two drawers 2 movably mounted on the upper end of one side of the bedside table body 1, an ultraviolet disinfection module 4 disposed inside the drawers 2, a cabinet door 3 rotatably disposed on the lower end of one side of the bedside table body 1, and an ozone disinfection module 5 and a driving component 6 mounted on the inner wall of the bedside table body 1 below the drawers 2;

[0030] The driving component 6 includes a control module 61, a power management module, a door opening sensing module, and a relay module connected to the hospital HIS system through a communication interface. The ultraviolet disinfection module 4, the ozone disinfection module 5, the power management module, the door opening sensing module, and the relay module are all electrically connected to the control module 61.

[0031] The ultraviolet disinfection module 4 emits UVC band ultraviolet rays to directly destroy the DNA / RNA structure of microorganisms, usually completing disinfection within 15-30 minutes without producing any chemical residues;

[0032] The ozone disinfection module 5 generates ozone gas to disinfect the interior of the bedside table. Oxidation destroys the cell structure of bacteria and viruses, deeply disinfecting areas that are difficult to directly irradiate. It effectively kills most pathogens and decomposes them into oxygen after disinfection, leaving no chemical residue.

[0033] The control module 61 is used to receive instructions from the hospital HIS system and coordinate the work of each module, monitor the disinfection process, and provide disinfection feedback to the HIS system to realize intelligent automatic disinfection process and remotely monitor and manage disinfection operations.

[0034] The relay module is used to control the switch of high-power equipment (ultraviolet lamp, ozone generator) and isolate high and low voltage circuits to achieve low current control of high current equipment and protect the control module from high voltage interference;

[0035] The door opening sensing module is used to detect the opening and closing status of the cabinet door 3 to prevent accidental opening of the door during the disinfection process, ensure the relative airtightness of the disinfection environment, prevent ultraviolet / ozone leakage during the disinfection process, and avoid human interference in the disinfection process.

[0036] When a patient is admitted and discharged, staff enter the patient's information into the hospital's HIS system and assign the patient a bed. The HIS then issues instructions to automatically disinfect the furniture in the corresponding bed. This reduces the need for medical staff to disinfect furniture each time a patient is admitted and discharged, saving time and improving work efficiency.

[0037] When the disinfection system (UV disinfection module 4 and ozone disinfection module 5) is working, if someone opens the cabinet door 3 and drawer 2, the disinfection system will automatically shut down to prevent human harm. When the person closes the cabinet door 3 and drawer 2, the disinfection system will restart and the disinfection time will be reset.

[0038] The communication interface includes an RS485 interface 62 and an RJ45 interface 63 provided on the control module 61 . The hospital HIS system issues disinfection instructions to the control module 61 through the RS485 interface 62 or the RJ45 interface 63 .

[0039] The ultraviolet disinfection module 4 includes an optocoupler J8, a relay JK1, and a transistor Q10. A resistor R19 is connected between pin 4 of the optocoupler J8 and the base of the transistor Q10. The collector of the transistor Q10 is connected to pin 2 of the relay JK1. Pin 2 of the relay JK1 is also connected to a capacitor C10 and a diode D10 arranged in parallel.

[0040] The ultraviolet disinfection module 4 also includes a connector JP1, pin 1 of the connector JP1 is connected to pin 5 of the relay JK1, pin 2 of the connector JP1 is connected to pin 3 of the relay JK1, pin 1 of the optocoupler J8 is connected to a resistor R16 connected to 3.3V, and pin 4 of the optocoupler J8 is connected to a resistor R1 connected to 5V.

[0041] Optocoupler J8 is a TLP181. It houses an LED on the left and a phototransistor on the right. When a suitable current (provided by 3.3V and resistor R16) is applied to pin 1 of optocoupler J8, the LED illuminates, and the light shines on the right phototransistor, turning it on. Optocoupler J8 provides electrical isolation, preventing interference between upstream and downstream circuits while also transmitting low-voltage signals (3.3V side) to downstream circuits.

[0042] When the optocoupler is turned on, resistor R17 is used to limit the current flowing into the output side (pin 4) of the optocoupler J8, acting as a pull-up to ensure that the optocoupler J8 can reach the appropriate voltage value when outputting a high level.

[0043] After the optocoupler is turned on, resistor R19 limits the current flowing into the base of transistor Q10. According to the transistor current amplification principle, the collector current can be controlled by reasonably setting the base current.

[0044] Transistor Q10: When the optocoupler J8 is turned on and the base potential is appropriate (lower than the emitter potential), the transistor Q10 is turned on and can drive the subsequent load (such as relay JK1).

[0045] The ozone disinfection module 5 includes an ozone generating module connector Ozone, a blower connector Fan, a buzzer, a MOS transistor Q1 connected to the blower connector Fan, a MOS transistor Q2 connected to the ozone generating module connector Ozone, and a MOS transistor Q3 connected to the buzzer.

[0046] A diode D0 is connected between pins 1 and 2 of the buzzer. Pin 1 of the buzzer is also connected to a resistor R8. The resistor R8 is connected to pin 2 of the ozone generator module connector Ozone and pin 2 of the blower connector Fan.

[0047] A resistor R11 is connected between pins 1 and 2 of the MOS tube Q1, a resistor R10 is connected to pin 1 of the MOS tube Q1, a resistor R13 is connected between pins 1 and 2 of the MOS tube Q2, a resistor R12 is connected to pin 1 of the MOS tube Q2, a resistor R15 is connected between pins 1 and 2 of the MOS tube Q3, and a resistor R14 is connected to pin 1 of the MOS tube Q3.

[0048] MOS transistors Q1, Q2, and Q3 act as switches, controlling a larger load current with a small gate control signal, thereby achieving control of a strong current load by a weak current, and have the advantages of small on-resistance and low power consumption.

[0049] Resistors R10, R12, and R14 are used to limit the current flowing into the gate of the MOS tube and protect the gate of the MOS tube from large current shocks; resistors R11, R13, and R15 are pull-down resistors. When there is no control signal input, the gate of the MOS tube is pulled to a low level (grounded) to ensure that the MOS tube is in the cut-off state and prevent false triggering.

[0050] The ozone generating module is connected via the PH2.0-2P interface. When the MOS tube Q2 is turned on, the ozone generating module works to generate ozone for disinfection.

[0051] The relay module includes a chip U1 and a relay K1. A diode D19 is connected between pins 1 and 2 of the relay K1, and pins 4 and 8 of the chip U1 are both connected to pin 2 of the relay K1. A resistor R49, a transistor Q19, and a resistor R39 are connected in series between pin 3 of the chip U1 and pin 1 of the relay K1.

[0052] Pin 6 of the chip U1 is connected to a resistor R19 and an adjustable resistor R29 respectively. One end of the resistor R19 is connected to pin 2 of the relay K1. Pin 5 of the chip U1 is connected to a capacitor C19. The capacitor C19, the adjustable resistor R29, and the emitter of the transistor Q19 are all connected to pin 1 of the chip U1.

[0053] When chip U1 outputs a high level, resistor R49 provides a suitable bias to the base of transistor Q19, turning it on. When chip U1 outputs a low level, the base potential of transistor Q19 decreases, turning it off. Transistor Q19 is used to amplify the output signal of chip U1 and drive relay K1.

[0054] When the transistor Q19 is turned on, the coil of the relay K1 is energized, generating a magnetic field to activate the contacts of the relay K1, thereby realizing circuit switching (operation switching between the ultraviolet disinfection module 4 and the ozone disinfection module 5).

[0055] When the coil of relay K1 is de-energized, a reverse electromotive force will be generated. Diode D19 provides a discharge circuit for this reverse electromotive force to prevent the reverse electromotive force from damaging components such as transistor Q19.

[0056] The door opening sensing module includes a connector CN1, a resistor R1, a light-emitting diode D1 and an orpiment switch arranged in series, and a resistor R2 and a light-emitting diode D2 arranged in series. The light-emitting diode D2 is connected to the orpiment switch. The resistors R1 and R2 are connected to pin 3 of the connector CN1, and the connection terminal of the light-emitting diode D1 and the orpiment switch is connected to pin 1 of the connector CN1. The orpiment switch and the light-emitting diode D2 are both grounded.

[0057] Resistor R1 is the current limiting resistor of the light emitting diode D1, which prevents excessive current from damaging the light emitting diode D1. When the orpiment switch is closed, the circuit is turned on, and current passes through the light emitting diode D1, causing it to emit light, indicating that the orpiment switch is in the closed state.

[0058] During use, when the patient goes through the discharge / admission procedures, the HIS system sends a disinfection instruction to the control module, the control module receives the instruction and verifies the open and closed status of the cabinet door 3 (confirms that the cabinet door 3 is closed through the door opening sensing module); then the control module cuts off the user-accessible function through the relay module, and the power module supplies power to the disinfection system (ultraviolet disinfection module 4 and ozone disinfection module 5). The control module starts the ultraviolet disinfection module 4 and the ozone disinfection module 5 according to the preset program. The ozone disinfection module 5 runs first to disinfect the air and the overall space in the cabinet, and the ultraviolet disinfection module 4 is then started to perform enhanced disinfection of the surface of the cabinet 3;

[0059] During the disinfection process, the door opening sensing module continuously monitors. If it detects that the cabinet door 3 is open, the disinfection is stopped immediately, and after closing the cabinet door 3, the disinfection is restarted and the timing is restarted. After the preset disinfection time is reached, the control module 61 turns off the disinfection system in turn and sends a disinfection completion confirmation to the HIS system.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
