Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical suction or pumping equipment, in particular to an intelligent pleural effusion drainage monitoring and remote alarm device. BACKGROUND

[0002] Pleural effusion drainage is a common means for treating pleural effusion, pneumothorax and other diseases in clinical practice. The core of it is to maintain the airtightness and patency of the drainage system. During the drainage process, if the pipeline is in contact with external air, it may cause serious complications such as pleural infection and aggravated pneumothorax. If the drainage tube is blocked, it may affect the discharge of effusion, and even lead to treatment failure. Therefore, ensuring the airtightness and patency of the pipeline is the key to the safety of pleural drainage.

[0003] Currently, clinical practice mainly relies on medical staff to observe the drainage condition regularly, including checking the liquid level fluctuation of the drainage bottle, whether the pipeline connection is tight, and whether there is blockage, etc. However, manual monitoring has a lag, and it is difficult to find pipeline air leakage or blockage in time, especially at night or when medical staff are busy, which may delay treatment and increase patient risk.

[0004] To solve this problem, some monitoring schemes have been proposed in the prior art, for example, patent CN118403239A discloses a closed pleural drainage intelligent monitoring system, which detects the drainage state through a sensor and alarms when there is an anomaly. However, this scheme only provides an alarm function and cannot automatically perform emergency treatment (such as clamping the pipeline to prevent air from entering the chest cavity), which has the risk of delayed response. In addition, the monitoring device in this scheme is set on the drainage bottle, which requires the production of new drainage devices, not only the cost is high, but also it is difficult to be compatible with the standardized drainage system widely used in existing clinical practice, which limits its promotion.

[0005] Therefore, there is an urgent need for an intelligent monitoring and automatic processing scheme with low cost and high compatibility, which can quickly respond when the pipeline is abnormal, automatically close the pipeline to maintain airtightness, and adapt to existing drainage devices for easy clinical application.

[0033] The frame 6 is connected with a hook 8 through a hanging rope 7.

[0035] The micro motor-driven closed tube clamp 9 comprises a pair of hinge plates 12, the hinge plates 12 are hinged through a hinge column 10, a torsion spring 11 is installed between the two hinge plates 12, a tube sleeve 13 and a pressing plate 15 are sequentially arranged at the end of the hinge plate 12 away from the hinge column 10, the inner wall of the tube sleeve 13 is provided with a clamping plate 14, a screw rod sleeve 20 is installed on the pressing plate 15 of one side hinge plate 12, a screw rod 18 and a micro motor 19 driving the screw rod 18 to rotate are rotatably installed on the pressing plate 15 of the other side hinge plate 12, and the screw rod 18 is in threaded connection with the screw rod sleeve 20.

[0040] As shown in Figure 2 and Figure 3 , the full bottle liquid level sensor 23 is installed on the front side wall of the frame 6 and faces the bottle opening of the drainage bottle 1, and the water seal surface liquid level sensor 24 is installed on the front side wall of the frame 6 and faces the bottom of the water seal bottle 2. During the drainage process, the full bottle liquid level sensor 23 monitors the liquid level in the drainage bottle 1 in real time, and when the liquid reaches the bottle opening position, the sensor transmits a signal to the control chip in the control box 25; the water seal surface liquid level sensor 24 monitors the liquid level of the water seal surface in the water seal bottle 2 in real time, and if the liquid level is abnormal, the signal will also be transmitted to the control chip.

[0041] As shown in Figure 1As shown, the control box 25 is arranged on the front side of the frame 6, and the touch screen 26 on the control box 25 can be operated and display relevant information, and the speaker 27 is used to issue an alarm sound. When the control chip receives an abnormal signal from the full bottle liquid level sensor 23 or the water seal surface liquid level sensor 24, on one hand, the control chip controls the speaker 27 to issue an alarm sound to remind the surrounding personnel, and on the other hand, the control chip transmits the abnormal information to the nurse station and the doctor's office PC through the wireless transmission module, so that the medical staff can timely understand the situation.

If the liquid level of the drainage bottle 1 or the water seal bottle 2 is lower than the set value, the control chip will immediately control the micro electric closed pipe clamps 9 to close the drainage tube 3 and the communication tube 4, so as to prevent air from entering the chest cavity or the abnormal flow of the effusion, and maintain the airtightness of the drainage system. Figures 6-8 As shown, when the micro electric closed pipe clamp 9 works, the micro motor 19 drives the screw rod 18 to rotate, since the screw rod 18 is threadedly connected with the screw rod sleeve 20, and the screw rod 18 and the screw rod sleeve 20 are respectively arranged on the rotating plate 17 on the pressing plate 15 of the two side hinge plates 12, the micro motor 19 drives the screw rod 18 to rotate, the two side hinge plates 12 rotate around the hinge column 10, and the clamping plate 14 in the pipe sleeve 13 clamps the drainage tube 3 or the communication tube 4, so as to automatically close the pipeline, prevent air from entering the chest cavity or the abnormal flow of the effusion, and maintain the airtightness of the drainage system.

[0042] The clamping plate 14 is provided with a plurality of parts capable of increasing the friction between the clamping plate 14 and the pipe wall, so as to avoid the micro electric closed pipe clamp 9 from sliding along the pipe wall.

[0044] In this embodiment, the full bottle liquid level sensor 23 and the water seal surface liquid level sensor 24 are used to monitor the liquid level of the drainage bottle 1 and the water seal bottle 2 in real time, once an abnormality occurs, the control chip can immediately control the micro electric closed pipe clamp 9 to automatically close the drainage tube 3 and the communication tube 4, so as to quickly respond and automatically execute emergency treatment, and avoid the air from entering the chest cavity or the abnormal discharge of the effusion due to the delay of the response. The control chip transmits signals to the nurse station and the doctor's office PC through the wireless transmission module, when an abnormality occurs, not only the speaker 27 can issue an alarm sound on the spot, but also the information can be transmitted to the medical staff in time, so that the medical staff can quickly understand the situation and take corresponding measures no matter where they are, and the processing efficiency of the abnormal situation is further improved. In this embodiment, the frame 6 is only used to place the existing drainage bottle 1 and the water seal bottle 2, the micro electric closed pipe clamp 9 is sleeved on the drainage tube 3 and the communication tube 4 to realize the monitoring and automatic closing of the pipeline, which can well adapt to the existing drainage device, is convenient for clinical popularization and application, and reduces the promotion cost.

[0045] Embodiment 2: please refer to Figures 1-3, an intelligent pleural effusion drainage monitoring and remote alarm device, which differs from Example 1 in that a high-definition camera 22 is also installed on the frame 6, and the high-definition camera 22 records the drainage bottle 1 image in real time. The high-definition camera 22 is electrically connected to the control chip.

[0046] The control chip is also equipped with an image processing unit, which processes the image information of the drainage bottle 1 recorded by the high-definition camera 22 in real time. The control chip uses an intelligent algorithm to analyze the image information to determine whether the drainage fluid is interrupted or bleeding.

[0047] Working principle of this embodiment:

[0048] like Figure 2 and Figure 3 As shown, during drainage, a high-definition camera 22 mounted on the frame 6 records the drainage bottle 1 in real time, converting the dynamics of the drainage fluid within the bottle 1 into image signals. Because the high-definition camera 22 is electrically connected to the control chip, these image signals are continuously transmitted to the control chip. An image processing unit on the control chip receives the image signals from the high-definition camera 22 and processes them in real time. The image processing unit performs operations such as noise reduction and enhancement on the image to improve image quality and enhance subsequent analysis.

[0049] The control chip uses an intelligent algorithm to analyze the processed image information. By identifying the flow of drainage fluid within the drainage bottle 1, it determines whether the drainage fluid has been interrupted. For example, if the drainage fluid position remains unchanged for a period of time, it can be considered interrupted. Simultaneously, based on characteristics such as the color and transparency of the drainage fluid, the intelligent algorithm compares the information with pre-set normal and abnormal bleeding image features to determine whether abnormal bleeding is present. Once a flow interruption or abnormal bleeding is determined, the control chip immediately triggers subsequent actions, such as automatic pipeline closure and alarms, such as an alarm through speaker 27, and transmits abnormal information to the nurse's station and the doctor's office PC via a wireless transmission module.

[0050] This embodiment uses a high-definition camera 22 and an image processing unit to record the image of the drainage bottle 1 in real time and process and analyze it. It also uses an intelligent algorithm to accurately determine whether the drainage fluid is interrupted or bleeding, and promptly triggers automatic closure and alarm of the pipeline to assist medical staff in rapid processing, further improving the accuracy and timeliness of monitoring the drainage status of pleural effusion.

[0051] Example 3: An intelligent pleural effusion drainage monitoring and remote alarm device, which differs from Example 1 in that a level sensor is further provided at the bottom of the frame 6, the level sensor is used to monitor whether the frame 6 is tilted, and the level sensor is electrically connected to the control chip.

[0052] Working principle of this embodiment:

[0053] The embodiment can monitor the state of the frame body 6 in real time. Once the frame body 6 is tilted, the horizontal sensor can timely send a signal to the control chip, so that the situation that the drainage tube 3 is pressed, twisted or separated from the tube due to the tilting of the frame body 6 can be found in time. In combination with the original alarm function of the device, medical staff can be quickly reminded to handle, the risk of the patient is reduced, and the safety and reliability of drainage are improved.
