[0002] The current chest drainage devices include drainage instruments and water seal bottles. They are mainly used in surgical operations for chest drainage. The effusion or gas in the patient's chest cavity is drained to the bottle through a pipeline. Currently, most water seal bottles use passive single-chamber bottles and multi-chamber bottles to collect chest cavity gas and fluid. Such products have no sensing or measurement functions, and require medical staff to make frequent inspections, increase work intensity, and patients often have to extubate and intubate multiple times, which adds mental and economic burdens to patients.

[0003] For example, CN213911651 U discloses a water seal bottle with a constant liquid level, including a water seal bottle body, a chest drainage tube and a vent, wherein the water seal bottle body contains disinfectant, the top of the water seal bottle body has a jack for the chest drainage tube to pass through, and the chest drainage tube is immersed in the disinfectant in the water seal bottle body, and also includes a fluid effusion bottle sleeved on the outside of the water seal bottle body, the fluid effusion bottle and the water seal bottle body form a whole, and a liquid storage cavity is formed between the outside of the water seal bottle body and the inside of the fluid effusion bottle, and the side of the water seal bottle body is provided with a drain port that passes through the liquid storage cavity; the present invention has a simple structure and is easy to use. By providing the fluid effusion bottle and the drain port, the liquid level in the water seal bottle body is relatively constant, thereby avoiding the liquid level in the water seal bottle body exceeding the highest range of the chest drainage tube outlet plane, resulting in the situation that the gas in the chest cavity is difficult to be discharged, thereby reducing the medical risks caused by untimely treatment by medical personnel. This product still does not have the function of real-time monitoring and alarm.

[0004] Another example is CN211157576U, which provides a new water seal bottle, including a water seal bottle, a drainage tube, a three-way tube, a drainage bag and a water seal bottle bracket; a water seal bottle bracket is arranged outside the water seal bottle, and a hook is arranged on the left and right sides of the water seal bottle bracket, respectively; the water seal bottle is connected to one side of the three-way tube through the drainage tube, and the other interface of the three-way tube is connected to the chest drainage tube, and the remaining three-way tube interface is connected to the drainage bag through the drainage tube, and the height of the drainage tube on one side of the drainage bag is lower than the height of the drainage tube at the end of the water seal bottle, and the three-way tube is made of silicone rubber or polyurethane, and the three-way tube is connected to the water seal bottle and the drainage bag side, respectively, and a switch valve is arranged. On the basis of the original water seal bottle, the present invention connects another drainage tube to the drainage tube side, connects the drainage bag below, and connects the three-way tube in the middle, so that a large amount of flushing fluid flows into the drainage bag on one side, and the liquid in the drainage bag can be dumped at any time, so as to reduce the replacement of water seal bottles and reduce the cost burden of patients. The above problems also exist. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] In some embodiments, please refer to the attached instructions. Figure 1 A chest drainage monitoring device is provided on a water seal bottle 1, wherein the water seal bottle comprises a fluid collection cavity 18 and a water seal cavity 22, and the water seal cavity 22 and the fluid collection cavity 18 are connected by a water seal tube 23. Figure 1 Taking the water seal bottle 1 as an example (the arrangement of water seal bottles of other structures is consistent), the chest drainage monitoring device includes:

[0027] A bubble detection module, the bubble detection module includes a bubble sensor 3, the bubble sensor 3 is located near the water seal pipe outlet of the water seal pipe 23 on one side of the water seal chamber 22, and is used to detect bubbles emerging from the water seal pipe outlet;

[0028] A liquid level detection module, the liquid level detection module includes a liquid level sensor 13, the liquid level sensor 13 is arranged on one side of the liquid accumulation chamber 18 of the water seal bottle, and is used to detect the liquid level height in the liquid accumulation chamber 18;

[0029] The power module 5 is used to provide power to the bubble detection module and the liquid level detection module.

[0030] The bubble detection sensor 3 can detect the number of bubbles emerging from the outlet of the water seal tube 23. The bubble detection module records the number of bubbles, so that the patient's chest leakage can be monitored in real time. If the leakage is abnormal, the medical staff can be prompted to take timely countermeasures. There is no need for medical staff to observe regularly as in the prior art, which greatly reduces the work intensity of medical staff and improves safety. The liquid level sensor 13 can detect the liquid level height in the effusion cavity 18 in real time. These data values ​​can be recorded in the liquid level detection module in real time or regularly. When it approaches or exceeds the maximum liquid level alarm threshold, it can remind medical staff to deal with the effusion in time, which also reduces the work intensity of medical staff and improves safety. Even when the patient is recuperating at home, he can get timely reminders to take appropriate measures.

[0031] In order to make full use of the existing passive water seal bottles, such as Figure 1For example, the chest drainage monitoring device can be made into a module that is independent of the water seal bottle. The module can be used with newly produced water seal bottles or with existing water seal bottles in stock and in use. It also includes a base 10, which is used to place the water seal bottle. The base 10 is close to the outer wall of the water seal cavity 22 and is provided with a bubble sensor mounting portion 30 at the outlet of the water seal pipe 23. The bubble sensor 3 is arranged on the bubble sensor mounting portion 30; the base 10 is close to the outer wall of the effusion cavity 18 and is provided with a liquid level sensor mounting portion 130. The liquid level sensor 13 is arranged on the liquid level sensor mounting portion 130.

[0032] In some embodiments, a data processing module is also included, and the data processing module is connected to the bubble detection module and the liquid level detection module for processing and / or storing the bubble data and liquid level data transmitted by the bubble detection module and the liquid level detection module. In this way, both data can be stored, and can also be downloaded through a data interface such as a USB, or uploaded to the cloud or a user terminal (such as a mobile phone APP) through a data cable, so that it can be checked at any time and used to analyze changes in the condition.

[0033] In some embodiments, the data processing module includes a data analysis module, which is used to process the bubble data and liquid level data transmitted by the bubble detection module and the liquid level detection module into chart data. The bubble data and liquid level data change over time. The prior art relies on the regular observation and recording by medical staff, which is very time-consuming and laborious, and it is impossible to understand the time point of the sudden change. The data chart can draw a clear data change curve according to the data value corresponding to the set unit time, which can provide medical staff with a clear understanding of the patient's relevant situation and provide strong data support for auxiliary analysis of the patient's status.

[0034] In some embodiments, the data processing module further includes a remote communication module and a client, and the remote communication module transmits the bubble data, liquid level data and / or chart data transmitted by the bubble detection module and the liquid level detection module to the client. In this way, medical staff can remotely understand the relevant situation and handle related matters more quickly and conveniently. Even when the patient is recuperating at home, the medical staff can understand the relevant situation at any time and provide relevant guidance and emergency treatment to the patient in real time.

[0035] In some embodiments, the data processing module also includes an alarm module, which is preset with a gas leakage alarm threshold and a liquid level alarm threshold. When the bubble data and / or the liquid level data exceed the corresponding gas leakage alarm threshold and the liquid level alarm threshold respectively, the alarm module sends an alarm signal. The alarm signal includes but is not limited to one or more of sound, light, color, warning information marked in the chart data, and remote sending of alarm information to trigger a client alarm.

[0036] In some embodiments, the base 10 is provided with a fixed lock 24 for fixing the water seal bottle, which is used to fix the split water seal bottle or the existing water seal bottle to the base, and the bubble sensor mounting part 30 and the liquid level sensor mounting part 130 can also be used as a part of the locking structure of the fixed lock water seal bottle device.

[0037] In some embodiments, a display screen 2 is provided on the side wall of the base, and the base 10 is provided with a cavity, in which a circuit board 6 and the power module 5 are provided.

[0038] In some embodiments, the liquid level sensor 13 is a capacitive liquid level sensor, which is in the shape of a flat plate and is fixed on the side of the liquid level sensor mounting portion 130 facing the water seal bottle.

[0039] The present invention also provides a water seal bottle, comprising any one of the above-mentioned chest drainage monitoring devices. Figure 1 The body of the water seal bottle in the example is divided into two left and right cavities by a partition 19. The left side is a water seal cavity 22, and the right side is a liquid accumulation cavity 18. A liquid inlet pipe 17 is provided on the upper wall of the liquid accumulation cavity 18, and a backflow prevention membrane 16 is provided at the bottom of the liquid inlet pipe 17. A water seal tube 23 is installed in the water seal cavity 22, and its upper end inlet passes through the upper part of the partition 19 and enters the upper space of the liquid accumulation cavity to prevent the accumulated liquid in the liquid accumulation cavity 18 from entering the water seal tube 23. The lower end outlet of the water seal tube 23 is located at the lower part of the water seal cavity 22 and below the water surface. A safety valve 20 is provided on the upper wall of the water seal cavity 22 (this interface can also be used as a water injection hole, and a pressure sensor can also be set). A liquid level scale 12 is provided on one side wall of the liquid accumulation cavity 18 of the water seal bottle. Generally, the water seal bottle is made of transparent or translucent material to facilitate the observation of the liquid level and bubbles. Figure 1 In the example, the upper and lower installation positions of the water seal bottle corresponding to the liquid level sensor 13 are respectively provided with an upper level limit block 14 and a lower level limit block 11. These two components are used to accurately define the installation position of the liquid level sensor to ensure the consistency and accuracy of the installation of the liquid level sensors 12 of all water seal bottles. The upper level limit block 14 and the lower level limit block 11 can also be provided with a buckle or hook structure to facilitate the connection with the buckle or hook on the external fixed object to ensure that the water seal bottle is reliably fixed to prevent tilting or tipping. The left and right ends of the upper wall of the water seal bottle 1 are respectively provided with a hook 21 and a buckle hook 15. The bottom of the base 10 is provided with a vibration-damping and anti-slip foot pad 25. Figure 1 In the example, a color-changing indicator light 9, a power switch 8 and a USB interface 7 are provided on the side wall of the base.

[0040] The working principle is to Figure 1The existing water seal bottle or the supporting water seal bottle is placed on the base, and the water seal bottle is fixed by moving the steam drum sensor fixing part 30 and the liquid level sensor fixing part 130, and locked by fixing the lock buckle 24. Add water through the safety valve 20, overflow the bottom of the water seal chamber 23 by 2cm, connect the liquid inlet pipe 17 to the patient end, and turn on the patient end pipeline switch. At this time, if there is gas in the patient's chest cavity, the gas enters the effusion cavity 18 through the liquid inlet pipe 17 and the anti-reflux membrane 16, and then under pressure, through the water seal pipe 23 on the partition 19, bubbles emerge from the water, and the steam drum sensor 3 records the bubble situation and stores it in the bubble detection module or data analysis module. If it is pleural effusion, it passes through the liquid inlet pipe 17 and the anti-reflux membrane 16 and falls into the effusion cavity 18. As the liquid level increases, the liquid level sensor 13 records the liquid level change and stores it in the liquid level detection module or data analysis module. After a certain time period, such as 7 days or at the doctor's request, the device is returned to the doctor together. The doctor exports the data through USB to form a curve and judges whether it is necessary to remove the tube or extend the time of removing the tube, which greatly facilitates doctors and patients. It is also possible to wirelessly upload and download relevant data through the communication module and view relevant data in real time. Through fault alarms, serious leaks, blockages, and liquid fullness, all the information that occurs can be displayed on the display screen and the remote terminal.

[0041] The battery can be selected as a rechargeable battery, and the use time can be extended by using an external power supply through the USB interface.

[0042] The present invention can be integrated into the water seal bottle during its production, or a chest drainage monitoring device with a base can be independently examined. The existing water seal bottle can be directly placed on the monitoring device, so that the traditional passive water seal bottle is transformed into an active water seal bottle. Through liquid level detection and steam drum detection, the patient's chest leakage and pleural effusion can be monitored in real time, providing a convenient basis for medical staff to take timely response measures.

[0043] A data processing module can also be added to calculate and obtain a series of data, which can be provided to doctors as a basis for clinical judgment, greatly reducing the probability of mis-extubation. At the same time, through bubble calculation, abnormal leakage can be detected and an alarm can be issued for early prevention.

[0044] The present invention can utilize the existing compliant chest drainage devices on the market, place them on the equipment of the present invention, generate data collection, data analysis, and alarm for abnormalities. Especially for the later stage of the hand, after the patient returns home, continuous drainage is still required, and 24-hour monitoring is carried out. In the absence of a doctor, the advantages of this device can be fully utilized to record leakage parameters and drainage volume at any time. When required to return to the hospital for a follow-up examination, the doctor exports the data through USB (or Bluetooth or WIFI for remote data upload and download) to make an accurate diagnosis, such as whether the leakage is constantly decreasing over time, the lung function is gradually recovering, and over time, the pleural effusion slowly exudes less. It can reach the normal range, thereby providing accurate guidance on whether to remove the tube and determine the patient's recovery.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
