[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figure 1 As shown in the figure, an embodiment of this utility model proposes a weighing and data acquisition device for medical waste treatment equipment, comprising:

[0038] 11. A tray with a space for medical waste;

[0039] A sensing device is fixedly connected to the bottom of the tray 11, wherein the first end of the sensing device is fixedly connected to the bottom of the tray 11;

[0040] A weight data receiver electrically connected to the sensing device;

[0041] A weight data transmission controller electrically connected to the weight data receiver.

[0042] In this embodiment, medical waste is placed in the receiving space of the tray 11. A weight signal indicating the generation of medical waste is sensed and sent to a weight data receiver. The weight data receiver converts the analog signal into a digital signal and transmits it to other systems via a weight data transmission controller, for example, displaying it on a host computer screen or a remote server.

[0043] In an optional embodiment of this utility model, the weighing and data acquisition device of the medical waste treatment equipment further includes:

[0044] A fixing washer 13 is fixedly connected to the second end of the sensing device; the fixing washer 13 fixes the sensing device to the template 2 by fixing screws 131.

[0045] In this embodiment, as Figure 1 As shown, the fixing washer 13 provides support and fixation, stably fixing the sensing device on the template 2, which facilitates the weighing operation of the pallet 11.

[0046] In an optional embodiment of this utility model, the sensing device includes:

[0047] An elastomer 122, the first end of which is fixedly connected to the bottom of the tray 11, and the second end of which is fixedly connected to the fixing washer 13;

[0048] At least two strain gauges 121 are fixed to the surface of the elastic body 122;

[0049] The strain gauge 121 is bound to the surface of the elastic body 122 by a fixing coil, and the fixing coil is bolted to the elastic body 122.

[0050] In this embodiment, the elastomer 122 is a metal plate or other elastic material used to bear the weight of medical waste. When the weight of the waste material in the tray 11 is detected, the elastomer 122 undergoes a slight deformation. The strain gauge 121 is a sensitive element capable of sensing the deformation of the elastomer 122 and deforming accordingly. This deformation causes a change in its resistance, which is converted into a voltage change via a Wheatstone bridge, thereby converting the weight information of the medical waste into an electrical signal. The fixing coil is used to fix the strain gauge 121 and prevent it from falling off during the deformation of the elastomer 122. The fixing coil is typically made of metal and is fixed to the elastomer 122 by screws or other means; preferably, the fixing coil is bolted.

[0051] In an optional embodiment of the present invention, at least two strain gauges 121 are disposed on two opposite surfaces of the elastic body 122, and the strain gauges 121 are bonded to the elastic body 122.

[0052] In this embodiment, at least one pair of strain gauges 121 are provided, with each pair of strain gauges 121 adhered to two opposite surfaces of the elastomer 122. This symmetrical arrangement allows the strain gauges 121 to fully sense the deformation of the elastomer 122, generating a more accurate weight signal.

[0053] In an optional embodiment of this utility model, it further includes:

[0054] The travel limit screw 14 is fixed to the bottom of the elastic body 122 and is disposed opposite to the tray 11.

[0055] In this embodiment, the travel-limiting screw 14 prevents the elastomer 122 from undergoing excessive deformation and colliding with the template 2. The travel-limiting screw 14 specifies the rated weighing capacity of the sensing device.

[0056] In an optional embodiment of this utility model, the weight data receiver includes:

[0057] An amplifier electrically connected to the strain gauge 121;

[0058] The filter is electrically connected to the amplifier;

[0059] A microprocessor electrically connected to the filter;

[0060] The amplifier receives the medical waste weight data transmitted by the strain gauge 121, sends the amplified electrical signal of the medical waste weight data to the filter, and sends the electrical signal to the microprocessor.

[0061] In this embodiment, the weight data receiver is used to process and analyze the collected weight data, determine the loading status of the equipment, and generate corresponding reports or alarm information. It includes an amplifier, a filter, and a microprocessor. The amplifier amplifies the signal output by the sensing device, the filter removes noise from the signal, and the microprocessor processes the processed signal. It should be noted that the weight data receiver also includes an analog-to-digital converter electrically connected to the microprocessor. The analog-to-digital converter is electrically connected to the transmission controller, and the electrical signal is transmitted to the transmission controller as a digital signal after conversion by the analog-to-digital converter.

[0062] A schematic diagram of the weight data receiver is shown below. Figure 2 As shown, the weight data receiver and the sensing device are electrically connected via four pins, and the weight data receiver is also electrically connected to the power supply and the transmission controller via two pins. Specifically, the circuit diagram connecting the weight data receiver and the sensing device is shown below. Figure 3 As shown, the collector of the S8550 (transistor) is electrically connected to the output terminal of the sensing device, and the base pin of the S8550 (transistor) is electrically connected to the BASE (voltage regulator control output) pin of the microprocessor. The output terminal of the sensing device is simultaneously connected to a first resistor R1 and a second resistor R2, and the other end of the first resistor R1 is connected to the VFB (voltage regulator control input) pin of the microprocessor. The S8550 (transistor), the first resistor R1, and the second resistor R2 together form an amplifier and a filter. Figure 3The microprocessor shown internally includes an Input MAX (input multiplexing) module, an Analog Supply Regulator (ASU) module, a PGA (Programmable Gain Amplifier) ​​module, an ADC (Analog-to-Digital Converter) module, a Digital Interface (data interface) module, a Bandgap Reference (BNR) module, and an Internal Oscillator (internal oscillator) module. The microprocessor communicates with the microprocessor via...

[0063] In an optional embodiment of this invention, the amplifier is electrically connected to the strain gauge 121 via a lead wire 3. The first end of the lead wire 3 is electrically connected to the strain gauge 121 via a first connector, and the second end of the lead wire 3 is electrically connected to the amplifier via a second connector.

[0064] In this embodiment, the lead-out line 3 is used to transmit the electrical signal of the strain gauge 121 to the signal processing circuit. The lead-out line 3 is typically made of wire or cable and is connected to the strain gauge and the signal processing circuit via a connector.

[0065] The weighing and data acquisition device of this utility model for medical waste treatment equipment is also equipped with a user interface for displaying real-time weight data and issuing an alarm signal when the weight exceeds the set range. Users can view the weight data in real time through a touch screen or computer terminal and set relevant management parameters.

[0066] The weighing and acquisition device of the above-mentioned medical waste treatment equipment of this utility model has higher measurement accuracy, stronger anti-interference ability and simpler structure, and can effectively monitor the weight of medical waste, ensuring the accuracy and safety of the medical waste treatment process.

[0067] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
