Description

Technical Field

[0001] This utility model relates to the field of chest drainage technology, specifically a chest drainage device with an automatic alarm function. Background Technology

[0002] In the medical field, thoracic drainage is a common treatment used to remove effusion, air, or other foreign objects from the pleural cavity in order to restore normal thoracic function and alleviate the patient's symptoms. Traditional thoracic drainage devices typically include a water bottle to collect the fluid draining from the patient's thoracic cavity, and a connected water-seal bottle to maintain negative pressure within the thoracic cavity and facilitate the smooth drainage of fluid.

[0003] However, in actual use, medical staff need to regularly check and adjust the liquid level in the water bottle to ensure it is within the appropriate range. This is because if the liquid level is too low, the water seal bottle may not be able to effectively maintain negative pressure, thus affecting the drainage effect; while if the liquid level is too high, it may increase the risk of liquid splashing or contamination. However, due to the busy work of medical staff, and possible negligence or forgetfulness, sometimes water is not added or the liquid level is not adjusted in time, which poses a potential threat to the patient's treatment effect and safety.

[0004] To address this issue, those skilled in the art have proposed a thoracic drainage device with an automatic alarm function. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a chest drainage device with an automatic alarm function. Due to the busy work of medical staff and the possibility of negligence or forgetfulness, there are sometimes situations where water is not added or the fluid level is not adjusted in time, which poses a potential threat to the patient's treatment effect and safety.

[0006] A chest drainage device with an automatic alarm function includes a storage tank for collecting chest drainage fluid.

[0007] A closed opening at the top of the water storage tank is located on the outside of the tank.

[0008] An ultrasonic sensor is installed on the water storage tank or a structure connected to it for non-contact measurement of the liquid level in the water storage tank.

[0009] The ultrasonic sensor is connected to an indicator light system. When the measured liquid level is lower than the preset sensing point, the indicator light system will light up a red light to issue an alarm.

[0010] The storage tank is equipped with a magnetic slide rail on its outer side for adjustable mounting of the ultrasonic sensor, allowing the user to adjust the liquid level corresponding to the sensing point as needed. The top of the storage tank is also equipped with an end cap, and a scale is also provided on the outer wall of the storage tank. A magnetic slider is installed on the outer side of the magnetic slide rail to limit the ultrasonic sensor to the outer side of the magnetic slide rail. Two connecting batteries are installed on the outer wall of the magnetic slider.

[0011] Preferably, it also includes an alarm system electrically connected to the ultrasonic sensing device, which automatically triggers an alarm signal when the liquid level fails to reach the standard height set by the magnetic slide rail.

[0012] Preferably, the ultrasonic sensing device includes a transmitter and a receiver that cooperate to measure the time difference from the emission to the reception of the ultrasonic wave, thereby calculating the liquid level height.

[0013] Preferably, it also includes a control unit for receiving data from the ultrasonic sensor, processing this information, and controlling the operation of the indicator system and alarm system according to preset logic.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By integrating ultrasonic sensing technology, this device can achieve accurate, non-contact measurement of the liquid level in the water bottle, avoiding errors and delays caused by manual observation or simple mechanical indicators. When the liquid level is lower than the preset standard, the alarm system is automatically triggered to promptly remind medical staff to add water or adjust the liquid level, effectively preventing treatment failure or safety risks caused by improper liquid level, and significantly improving the safety and effectiveness of thoracic drainage.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] As attached Figure 1To be continued Figure 2 As shown:

[0021] Example 1: According to Figure 1-2 As shown, this utility model provides a chest drainage device with an automatic alarm function, including a storage tank 1 for collecting chest drainage fluid;

[0022] An upper closed opening 3 is provided on the outside of the water storage tank 1;

[0023] An ultrasonic sensor 14 is installed on the water storage tank 1 or a structure connected to it for non-contact measurement of the liquid level in the water storage tank 1.

[0024] The ultrasonic sensor 14 is connected to an indicator light system. When the measured liquid level is lower than the preset sensing point, the indicator light system will light up a red light to issue an alarm.

[0025] A magnetic slide rail 11 is provided on the outside of the water storage tank 1 for adjustable mounting of the ultrasonic sensing device 14, allowing the user to adjust the liquid level height corresponding to the sensing point as needed. A top cover 2 is also provided on the top of the water storage tank 1. A scale 4 is also provided on the outer wall of the water storage tank 1. A magnetic slider 12 is installed on the outside of the magnetic slide rail 11 to limit the ultrasonic sensing device 14 to the outside of the magnetic slide rail 11. Two connecting batteries 13 are installed on the outer wall of the magnetic slider 12.

[0026] It also includes an alarm system, which is electrically connected to the ultrasonic sensor 14. When the liquid level does not reach the standard height set by the magnetic slide rail 11, an alarm signal is automatically triggered. The ultrasonic sensor 14 includes a transmitter and a receiver, which cooperate to measure the time difference from the transmission to the reception of the ultrasonic wave, thereby calculating the liquid level height.

[0027] An ultrasonic sensor 14 is mounted on the outside of the water bottle or on a structure closely connected to it, and includes a transmitter and a receiver. The transmitter emits ultrasonic signals, which are reflected back after encountering the water surface and received by the receiver. By measuring the time difference between the emission and reception of the ultrasonic waves, the height of the water surface, i.e., the liquid level, is calculated. The ultrasonic sensor is electrically connected to an indicator light system and an alarm system to transmit liquid level data and control the triggering of alarm signals.

[0028] The indicator light system is placed in a prominent position on the device, such as the side or top of the water bottle.

[0029] When the liquid level measured by the ultrasonic sensor is lower than the preset sensing point, the indicator light system will light up red, indicating that the liquid level is too low and needs to be added or adjusted.

[0030] Working principle: After the device is started, the ultrasonic sensor 14 begins to work. The transmitter emits ultrasonic signals into the water storage tank 1, which are reflected when they encounter the water surface. The receiver receives the reflected ultrasonic signals and converts them into electrical signals. By measuring the time difference between the transmission and reception of the ultrasonic waves, combined with the known speed of ultrasonic wave propagation and the relative positions of the transmitter and receiver, the control unit can calculate the water level, i.e., the liquid level. The user adjusts the ultrasonic sensor to the desired position using a magnetic slide rail to set the threshold for the liquid level sensing point. The control unit continuously receives the liquid level data from the ultrasonic sensor and compares it with the set threshold. If the liquid level is lower than the set threshold, the control unit will trigger the indicator light system to illuminate red, indicating that the liquid level is too low. When the liquid level is lower than the set threshold, in addition to the indicator light system illuminating red, the control unit will also activate the alarm system. The alarm system may include an audible alarm (such as a buzzer) emitting an alarm sound.
