Description

Technical Field

[0001] The present invention belongs to the technical field of surgical drainage monitoring, and in particular relates to an intelligent drainage fluid monitoring and alarm device based on weight sensing. Background Art

[0002] In modern medicine, drainage is a very common treatment method, widely used in various surgeries and disease treatments. For example, postoperative patients usually need to have a drainage tube placed to drain exudates, blood, etc. from the body, help observe the recovery of the surgical area, and prevent fluid accumulation from causing complications such as infection; patients with portal hypertension due to cirrhosis often need to have an abdominal drainage tube placed to drain ascites to reduce abdominal pressure and relieve symptoms; patients with pleural effusion need to drain the effusion through puncture to restore normal negative pressure in the chest cavity and improve respiratory function. According to incomplete statistics, in large general hospitals, the number of patients receiving drainage treatment can reach hundreds per day, involving multiple departments such as general surgery, cardiothoracic surgery, and urology. Most of the drainage devices commonly used in clinical practice are only marked with a scale to indicate the drainage volume, and medical staff rely on regular patrols to observe the drainage situation.

[0003] This traditional drainage monitoring method, which relies on scale prompts and manual timed inspections, has many obvious drawbacks. During the interval between inspections, the patient's internal condition may change dramatically, such as postoperative bleeding from ruptured blood vessels or tissues, which can significantly increase the amount of drainage fluid within a short period of time. For patients with cirrhosis and ascites, if the ascites drainage exceeds the expected amount, it can easily cause a drop in intra-abdominal pressure, hyponatremia and hypokalemia, and even worsen hepatic encephalopathy. For patients with pleural effusion, if more fluid than expected is drained at once, it may lead to hypotension, arrhythmias, etc. According to relevant medical accident statistics, medical accidents caused by the failure to promptly detect abnormal drainage fluid have been on the rise in the past few years, and some serious cases have even endangered the patient's life. In addition, manually reading scale data is not only inefficient but also easily interfered with by human factors, such as visual errors and recording negligence, making it difficult to ensure data accuracy.

The hook 131 has a J-shaped structure, with the opening of the hook 131 facing away from the connecting plate 101. The weight sensor is integrated into the hook 131. The weight sensor is based on the piezoresistive effect of metal foil. When the sensor is deformed by force, the resistance value changes linearly, which is converted into a voltage signal via a Wheatstone bridge circuit. This device uses a BF350-3AA sensor with a range of 0-5 kg ​​and an accuracy of ±0.5% FS. To accurately monitor the drainage fluid, the output of the weight sensor is electrically connected to the input of the control panel 123, which in turn is electrically connected to the input of the alarm module 128. When the weight sensor detects that the weight of the drainage fluid reaches a preset threshold, the control panel 123 will immediately trigger the alarm module 128, emit a clear and loud alarm sound and transmit the alarm signal to the terminal device, promptly reminding medical staff to pay attention to the condition of the drainage fluid.

[0049] The alarm module 128 includes an alarm light and a buzzer. The volume of the buzzer is ≥85dB. The alarm light is a three-color LED light (green light normal / yellow light warning / red light over limit). The alarm module 128 sets a multi-level alarm mechanism: Primary warning (70% threshold): The yellow light flashes slowly and does not trigger a remote alarm. Secondary alarm (100% threshold): The red light flashes quickly + a buzzer, and is pushed to the nurse station simultaneously. Emergency alarm (120% threshold): The frequency of the sound and light alarms is doubled, and a pop-up window is activated on the mobile terminal.

[0050] The hook 131 is also provided with an acceleration sensor, which can identify weight fluctuations caused by changes in the patient's body position to avoid false triggering.

[0051] A battery compartment is provided on the connecting plate 101, in which a rechargeable lithium battery is placed. The rechargeable lithium battery has a battery life of 72 hours. The device adopts a low-power design and automatically enters sleep mode when there is no liquid flow.

[0052] The specific operation process of this application is as follows:

[0053] 1. Fix the device to the bed rail, hang the drainage bag, and press the "Calibrate" button to clear the tare weight;

[0054] 2. Use the knob to set the alarm threshold to 100ml (corresponding weight ≈ 100g, needs to be calibrated according to liquid density);

[0055] 3. When the sensor detects a liquid weight ≥ 100g: the local red light flashes and an intermittent beep sounds, and an alarm message is sent to the nurse's station via the LoRa wireless network. The alarm continues until the nurse manually resets it.

[0056] In addition, this application has an optional flow calculation function: recording the drainage volume per unit time, assisting in judging the risk of postoperative bleeding, and being able to generate a drainage volume change curve based on historical data obtained from monitoring, supporting electronic medical record integration.

[0057] The weight detection error of this application is less than ±2%, the alarm response delay is less than 3 seconds, and the alarm sound can be clearly identified within 3 meters under 50dB environmental noise.

[0058] This application can not only monitor the weight changes of drainage fluid in real time and accurately, but also conduct in-depth analysis and intelligent processing of the data. When the weight of the drainage fluid reaches the set value or the weight change exceeds the set range, an alarm signal can be issued in a timely and accurate manner to remind medical staff to take appropriate measures. At the same time, the device should have the function of remote data transmission and storage, so that medical staff can obtain patient drainage data anytime and anywhere, providing a comprehensive and reliable basis for clinical diagnosis and treatment, thereby effectively improving medical efficiency, reducing medical risks, and enhancing patients' treatment experience and rehabilitation effects.
