However, manual monitoring of the color of the drainage fluid and the amount of bleeding requires a lot of manpower and time, and it is impossible to achieve real-time monitoring.

[0025] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0026] Example

[0027] The utility model aims to provide a drainage fluid monitoring device for timely feedback of the risk of severe bleeding after surgery. Figure 1 As shown, the drainage fluid monitoring device includes a housing 10 having a receiving chamber, in which drainage equipment such as a drainage bag, a drainage ball, or a drainage bottle can be carried. The housing 10 is provided with an image acquisition module 11, a weighing module 12, an audible and visual alarm 13, a display 14, a microprocessor, and a power supply assembly. Specifically:

[0028] The image acquisition module 11 is used to periodically collect the color and transparency of the drainage fluid. The image acquisition module 11 is embedded in the inner wall of the shell 10. The image acquisition module 11 includes an industrial camera, which is fixed to the inner wall of the shell 10 and close to the bottom of the shell 10, and the camera of the industrial camera is aimed at the drainage device. Preferably, the camera of the industrial camera is flush with the inner surface of the shell 10. The inner wall of the shell 10 is pasted with a light-absorbing material. Preferably, the light-absorbing material can be a black light-absorbing cloth, which is used to absorb reflected light and thus improve the image contrast. When in use, the drainage fluid is regularly photographed by the camera, and the image processing technology of the microprocessor is used to analyze the color and transparency of the liquid. If the image recognition algorithm finds that the color or transparency is significantly different from the preset normal parameters, a massive bleeding crisis may occur, thereby triggering the sound and light alarm 13 to alarm.

[0029] The weighing module 12 is used to monitor the increase rate of the drainage fluid per unit time in real time. The weighing module 12 is arranged at the bottom of the accommodation chamber. The weighing module 12 includes a strain gauge sensor for sensing weight changes and a bearing platform for carrying the drainage device. The strain gauge sensor is evenly distributed below the bearing platform to ensure the accuracy and stability of the measurement. Preferably, the strain gauge sensor is connected to the bearing platform through an elastic metal beam, and the elastic metal beam is arranged between the bottom of the accommodation chamber and the bearing platform. When in use, when the elastic metal beam is deformed by force, the strain gauge sensor will also deform accordingly, thereby changing its resistance value. The change will be detected by the electronic circuit and converted into an electrical signal to represent the weight applied to the bearing platform. The increase rate of the drainage fluid can be obtained by dividing the weight increased per unit time by the unit time. If the increase rate of the drainage fluid exceeds the set threshold, a severe bleeding crisis may occur, thereby triggering the sound and light alarm 13 to alarm.

[0030] A microprocessor and a power supply assembly are provided at the bottom of the housing 10. The microprocessor is used to receive and analyze data from the image acquisition module 11 and the weighing module 12. The power supply assembly is electrically connected to the image acquisition module 11, the weighing module 12, the microprocessor, the display 14, and the sound and light alarm 13. It should be noted that the microprocessor in the present utility model is a conventional chip already available in the market, and the microprocessor may preferably be an MSP430 series or an STM32 series.

[0031] The outer surface of the housing is provided with an audible and visual alarm 13 and a display 14. Figure 3 The sound and light alarm 13 is electrically connected to the microprocessor; the display 14 is used to display the data of the image acquisition module 11 and the weighing module 12 in real time.

[0032] The drainage fluid monitoring device provided by the utility model ensures that when abnormal changes occur in the drainage fluid, medical staff can be notified in the first time to take corresponding medical measures, thereby ensuring the safety of the patient.

[0033] Although the 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
