[0028] Example:

[0029] See also Figures 1 to 4 In this embodiment, a weighing device 1 includes:

[0030] A support table 10, wherein a weighing area 10a is provided on the support table 10, and the weighing area 10a is used for placing an operating table;

[0031] The weight detection module 20 is disposed in the weighing area 10a, and the weight detection module 20 is used to measure the mass information on the weighing area 10a and convert it into an electrical signal;

[0032] The control module 30 is disposed inside the support platform 10 and is informationally connected to the weight detection module 20. The control module 30 is used to convert the electrical signal from the weight detection module 20 into weight data;

[0033] The display component 40 is disposed on the table top and / or the peripheral side of the support platform 10 and is informationally connected to the control module 30 . The display component 40 is used to display the weight data from the control module 30 .

[0034] With such an arrangement, during clinical surgery, the operating bed 2 is placed on the weighing area 10a of the weighing device 1, and then the patient is placed on the operating bed 2. The weight detection module 20 can measure the mass information on the weighing area 10a, and convert it into an electrical signal and send it to the control module 30. The display component 40 displays the weight data processed by the control module 30 in real time. Medical staff can evaluate the changes in the patient's body fluids based on the changes in the weight data displayed by the display component 40, thereby accurately evaluating the patient's physiological state through the changes in the body fluids, which is beneficial for medical staff to timely adjust the intraoperative anesthesia dose and replenish the patient's body fluids.

[0035] Furthermore, if Figure 2 and Figure 4 As shown, the weight detection module 20 includes a plurality of weight sensors 21, each weight sensor 21 is fixed on the side of the table surface of the support table 10 away from the table surface; the weighing area 10a is centrally symmetrical, and each weight sensor 21 is symmetrically distributed along the symmetry center of the weighing area 10a. In this arrangement, when the weighing device 1 is working, the gravity of the operating table 2 and the patient on the weighing area 10a is evenly distributed to each weight sensor 21. Each weight sensor 21 can be evenly spaced in the weighing area 10a, or can be spaced along the side of the weighing area 10a. It is preferred to use a piezoelectric sensor or a strain sensor with higher accuracy as the weight sensor.

[0036] Furthermore, the weighing area 10a of the support platform 10 is rectangular, and the weight sensors 21 are arranged at intervals along the sides of the rectangular weighing area 10a.

[0037] Specifically, Figure 4 As shown, Figure 4(c) is a top view of the weighing device 1 in this embodiment. In this embodiment, the weight detection module 20 includes four weight sensors 21, each of which is arranged at the four corners of the rectangular weighing area 10a. In this way, the weighing device 1 can accurately measure the weight change on the weighing area 10a.

[0038] Furthermore, if Figure 1 and 2 As shown, the weighing device 1 further includes an input module 50 having a plurality of buttons, the input module 50 is arranged on the table surface and / or the peripheral side of the support table 10, and the information is connected to the control module 30;

[0039] The input module 50 is used to input various instructions to the control module 30 . The control module 30 is used to receive each instruction from the input module 50 and send weight data corresponding to each instruction to the display component 40 .

[0041] Furthermore, the display component 40 is used to display the initial weight data a1 , the real-time weight data a2 and the weight difference Δa from the control module 30 , wherein Δa=a1 −a2 .

[0042] Specifically, Figures 1 to 4 As shown, the working steps of the weighing device 1 are:

[0043] (1) Power on: Figure 3 As shown, the operating table is placed in the weighing area 10a of the weighing device 1, the patient is placed on the operating table and anesthetized, and the medical staff manipulates the input module 50 to input a power-on command to start the weighing device 1;

[0044] At this time, the weight detection module 20 measures the mass information on the weighing area 10a in real time and converts it into a weight data electrical signal. The quality information is the mass data of the operating table and the patient; the display component 40 will display the real-time weight data a2;

[0045] (2) Obtaining initial weight data a1: After the real-time weight data a2 displayed on the display component 40 is stable, the control input module 50 inputs a weight data selection instruction;

[0046] The control module 30 receives the instruction, selects the weight data electrical signal when the instruction is input, processes and sends it to the display component 40. At this time, the weight data when the weight data selection instruction is input is the initial weight a1, and the initial weight data a1 and the real-time weight data a2 are both displayed on the display component 40;

[0047] (3) Obtaining the weight difference Δa: During the operation, the real-time weight data a2 changes with the patient's body fluid condition. The control input module 50 inputs a weight difference calculation instruction. The control module 30 receives the instruction and calculates the difference between the initial weight data a1 and the real-time weight data a2 to obtain the weight difference Δa in real time. The display component 40 simultaneously displays the weight difference Δa, the initial weight data a1, and the real-time weight data a2. Medical staff can judge the patient's body fluid condition based on the weight difference Δa.

[0048] (4) Resetting the initial weight data a1: If the initial weight data a1 needs to be reselected, the control input module 50 inputs a reset command, and the control module 30 receives the command and resets the selected initial weight data a1. The medical staff can select new initial weight data a1 by repeating operation step (2), and then calculate the weight difference Δa by operation step (3);

[0049] (5) Shutdown: The control input module 50 inputs a shutdown command to shut down the weighing device 1 .

[0052] In the use scenario of clinical surgery, the keys of the input module 50 are physical keys, which can be convenient for medical personnel to operate, such as setting a touch panel 51 or a key panel, or setting a touch panel 51 and a key panel at the same time. The display screen 41 can be a liquid crystal screen (LCD), or other display screens such as an OLED display screen. The touch panel 51 and the display screen 41 are at least partially overlapped to facilitate medical personnel to operate and observe weight data, as long as the display area of ​​the display screen 41 is not blocked by the touch panel 51. The key panel is set along the edge of the display screen 41, which is also conducive to medical personnel observing the patient's body fluid conditions.

[0053] The touch panel may be a resistive touch screen, a capacitive touch screen, or other types of touch screens.

[0054] In this embodiment, if Figure 4 As shown, since the display screen 41 is stacked with the touch panel 51 , the label of the display screen 41 is indicated by a dotted line.

[0055] Furthermore, if Figure 4 As shown, the weighing device 1 further includes an inclined surface 11 extending from the peripheral side of the table surface of the supporting table 10 , and the inclined surface 11 is adjacent to the peripheral side of the weighing area 10 a .

[0056] The inclined surface 11 is provided to facilitate placing the operating table 2 on the tabletop of the support table 10 by pushing. The inclined surface 11 is only adjacent to the peripheral side of the weighing area 10a, which can prevent the movement of the operating table 2 from accidentally touching or damaging the display component 40 and the input module 50 on the operating area 10b. Figure 4 As shown, in this embodiment, the support platform 10 is preferably in a rectangular parallelepiped shape, and the inclined surface 11 is adjacent to a side of the weighing area 10a opposite to the operating area 10b, and extends from the surface of the support platform 10 to the ground.

[0057] Furthermore, if Figure 4 As shown, the control module 30 is disposed at a distance from the display assembly 40 along the thickness direction of the support platform 10 .

[0058] The control module 30 includes a display component 40 control terminal and a plurality of input terminals.

Each input terminal can be connected to an input module 50 having a physical key or a virtual input module 50. It can be understood that the control module 30 can also include a plurality of output terminals, each of which is connected to an external device to display the weight data from the control module 30. Specifically, the control module is an integrated display driver chip and a microprocessor chip. The model of the display driver chip is SSD1963, and the model of the microprocessor chip is STM32F446VET6. It should be noted that the models of the display driver chip and the microprocessor chip used above are only examples, and other chip models can also be selected.
