Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a body fluid drainage meter. Background Technology

[0002] Closed thoracic drainage is a commonly used surgical treatment that promotes lung re-expansion and restores normal intrathoracic pressure by draining gas and fluid from the pleural cavity. Currently, this drainage method mainly relies on thoracic drainage bottles. Referring to patent application CN106267389, the drainage bottle can generate negative pressure automatically, and the degree of negative pressure can be adjusted, which helps patients drain accumulated gas and fluid from the pleural cavity. However, it has the following drawbacks:

[0003] During operation, drainage bottles may tilt due to patient positioning or other reasons. The angle of tilt can affect drainage and even cause problems such as gas or liquid backflow. Currently, medical personnel mainly rely on visual observation of the color, amount, and properties of the drainage fluid, as well as the fluctuation of the water column inside the drainage bottle, to deal with bottle tilting. This method is not only inefficient but also lacks sufficient intelligence. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a body fluid drainage meter that effectively achieves intelligent operation and improves monitoring efficiency.

[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0033] like Figures 1 to 3 As shown, the body fluid drainage meter includes:

[0034] The monitoring device 1 includes a main body 11 and two side plates 12 and 13. The main body 11 is connected between the two side plates 12 and 13. A first recess 14 is formed between the two side plates 12 and 13. The first recess 14 is located on one side of the main body 11. Liquid level sensor groups 141 are respectively provided on the inner walls of the side plates 12 and 13 that form the first recess 14. The liquid level sensor groups 141 on the inner walls of the two side plates 12 correspond one to one.

[0035] Bottle body 2, the bottle body 2 includes a metering bottle 21 and a liquid collection bottle 22, the metering bottle 21 is disposed on the upper surface of the liquid collection bottle 22, and the metering bottle 21 is connected to the liquid collection bottle 22;

[0036] The two side plates 12 are detachably disposed on the upper surface of the liquid collection bottle 22, and the metering bottle 21 is located in the first recess 14.

[0037] The measuring bottle 21 is used to receive fluid drained from the pleural cavity. Since the measuring bottle 21 is engaged between the two side plates 12 and 13, the liquid level sensor group 141 on the inner walls of the two side plates 12 and 13 can be used to monitor the liquid level and overall tilt of the measuring bottle 21 in real time. This design replaces the existing method of manual observation, achieving real-time monitoring and significantly improving the monitoring effect and level of intelligence.

[0038] like Figures 1 to 3 As shown, the two side plates 12 and 13 have the same shape, both being rectangular, and the first recess 14 and the main body 11 are located on both sides of the length direction of the side plates 12 and 13, respectively.

[0039] The first recess 14 is exposed on the upper and lower surfaces of the two side plates 12 and 13, such that the monitoring device 1 is mounted from top to bottom on the upper surface of the liquid collection bottle 22, so that the metering bottle 21 is inserted into the first recess 14 formed between the two side plates 12 and 13. Furthermore, the first recess 14 is exposed on the left side of the two side plates 12 and 13, so that the metering bottle 21 can be viewed through the left side of the monitoring device 1.

[0040] The upper surface of the main body 11 is approximately flush with the upper surfaces of the two side plates 12 and 13. A display screen 111 can be installed on the upper surface of the main body 11 to display the liquid level and overall tilt status. The rear side of the main body 11 is approximately flush with the rear side of the two side plates 12 and 13.

[0041] like Figure 2 and Figure 3 As shown, the inner walls of the two side plates 12 and 13 are opposite to each other, and the first recess 14 is formed between the inner walls of the two side plates 12 and 13. Liquid level sensor groups 141 are respectively provided on the inner walls of the two side plates 12 and 13.

[0042] Specifically, each liquid level sensor group 141 includes multiple liquid level sensors, arranged from top to bottom in each group, with one-to-one correspondence between the liquid level sensors on the inner walls of the two side plates 12. Additionally, multiple groups of liquid level sensor groups 141 can be disposed on the inner walls of each side plate 12, 13. The multiple groups of liquid level sensor groups 141 on the inner walls of each side plate 12, 13 are arranged along the length of the side plate 12, 13, while the multiple liquid level sensors in each group are arranged equidistantly along the width of the side plate 12, 13.

[0043] The liquid level sensor includes a capacitive liquid level sensor. The working principle of the capacitive liquid level sensor in monitoring the liquid level in the measuring bottle 21 is as follows:

[0044] A capacitor consists of two conductive plates (electrodes) and an insulating medium (such as air, liquid, etc.) in between. The capacitance (C) of a capacitor is related to the area (A) of the conductive plates, the distance between the plates (d), and the dielectric constant (ε) of the medium, and is expressed by the formula: C = A / d.

[0045] When the liquid level in the metering bottle 21 changes, it causes a change in capacitance sensed by the capacitive level sensor: the dielectric constant of the liquid differs from that of the gas (usually air) when the liquid level changes. The rise or fall of the liquid alters the medium between the electrodes, thus changing the capacitance value. By scanning a matrix of multiple capacitive level sensors on both sides, it is determined whether the area between the electrodes is covered by liquid, thereby achieving liquid level measurement.

[0046] The working principle of the capacitive liquid level sensor for monitoring overall tilt is as follows:

[0047] When the entire system is placed stably, the capacitive level sensors of multiple sets of level sensor groups 141 at the same height should have the same capacitance. However, if the bottle body 2 is not placed stably, or the metering bottle 21 is not installed properly, the capacitive level sensors of multiple sets of level sensor groups 141 at the same height will obtain different capacitances, and in this case, it will be judged that the liquid level is tilted.

[0048] Simultaneously, during the tilting process, the specific tilting direction can be determined based on the different values ​​of the capacitive liquid level sensors at the same height of multiple liquid level sensor groups 141. Specifically, a left-side liquid level sensor group and a right-side liquid level sensor group are arranged from left to right on the inner wall of the first side plate 12. Since the capacitive liquid level sensors of the left-side liquid level sensor group and the right-side liquid level sensor group are one-to-one, the overall tilting direction can be determined by monitoring the capacitance values ​​on h1, h2, and h3, as the heights of h1, h2, and h3 increase.

[0049] For example, the capacitance values monitored by the left liquid level sensor group at heights h1, h2, and h3 are respectively represented as C11, C12, and C13, and the capacitance values monitored by the right liquid level sensor group at heights h1, h2, and h3 are respectively represented as C21, C22, and C23. When C11<C21, C12<C22, and C13<C23, it is determined that the whole is tilted to the right.

[0050] Further, when the whole is tilted to the right, the liquid will move to the right. For the right liquid level sensor, the liquid level will be closer to the electrode, thereby reducing the distance between the electrode and the medium. According to the capacitance formula, when the distance d decreases, the capacitance C will increase. Therefore, when C11<C21, C12<C22, and C13<C23, it is determined that the whole is tilted to the right.

[0051] In summary, most drainage bottles rely on scales to identify the volume of drainage fluid, but the scale accuracy is limited. When there is foam or viscous substance in the drainage fluid, it is easy to cause reading errors, making it difficult for medical staff to accurately grasp the patient's drainage condition and interfering with condition judgment. In the present application, through the combination of the monitoring device 1 and the bottle body 2, and by using the liquid level sensor group 141 on the monitoring device 1, the liquid level height in the metering bottle 21 is monitored, which can also be displayed through the display screen 111 on the monitoring device 1, and has high intelligence. The liquid level sensor group 141 on the monitoring device 1 can also monitor the overall tilt condition, which can also be displayed through the display screen 111, improving the monitoring efficiency and the degree of intelligence.

[0052] Reference Figure 2 and Figure 3 , a control board can be arranged inside the main body 11, and the control board is electrically connected to the display screen 111 and the liquid level sensor group 141 respectively, wherein the connecting lines can be hidden inside the main body 1, the side plate 12 and the side plate 13. The calculation of capacitance values, the judgment of tilt and the like are performed by the control board.

[0053] A power supply is arranged inside the main body 11, and the power supply is connected to the control board to provide electric energy for the operation of the control board and other components. A power compartment door is opened on the right side of the main body 11 for replacing the power supply.

[0054] A Type-C charging port is further arranged on the surface of the main body 11 for charging the power supply.

[0055] A wireless communication module is integrated on the control board for realizing signal connection with the outside such as mobile terminals and user terminals.

[0056] As Figure 4 and Figure 5As shown, the metering bottle 21 has a drain port 213, and the upper surface of the liquid collection bottle 22 has a liquid inlet 222. The drain port 213 and the liquid inlet 222 are connected by a suction pipe 24.

[0057] The measuring bottle 21 is located on the left side of the upper surface of the liquid collection bottle 22. The drain port 213 is provided on the lower right side of the measuring bottle 21. The inlet port 222 is provided on the right side of the upper surface of the liquid collection bottle 22. The suction tube 24 is located above the liquid collection bottle 22. By making reasonable use of space layout and reducing the length of the suction tube 24, it is still possible to connect the measuring bottle 21 and the liquid collection bottle 22.

[0058] refer to Figure 4 The lower surface of the metering bottle 21 is connected to the upper surface of the liquid collection bottle 22, and the distance between the drain port 213 and the lower surface of the metering bottle 21 is 5-10 cm.

[0059] The distance between the upper and lower surfaces of the metering bottle 21 defines the length of the metering bottle 21, and multiple level sensors of each level sensor group 141 are arranged at equal intervals along the length direction of the metering bottle 21.

[0060] The metering bottle 21 and the liquid collection bottle 22 are integrally connected. The two side plates 12 and 13 and the liquid collection bottle 22 can be fixed together by means of abutment, snap-fit, fasteners, etc., thus ensuring the stability of the liquid level sensor group 141 on the inner wall of the side plates 12 and 13 scanning the metering bottle 21. The metering bottle 21 can be made of transparent material to allow the liquid level sensor group 141 to scan the liquid inside the metering bottle 21.

[0061] like Figures 1 to 5 As shown, a second recess 15 is formed between the two side plates 12 and 13. The second recess 15 is located below the main body 11. After the lower ends of the two side plates 12 and 13 are connected to the upper surface of the liquid collection bottle 22, the liquid suction pipe 24 is hidden in the second recess 15. The space layout is reasonably utilized, making the structure more compact.

[0062] like Figure 4 and Figure 5 As shown, a solenoid valve 241 is provided on the liquid suction line 24, and a protrusion 221 is provided on the upper surface of the liquid collection bottle 22. The protrusion 221 supports the solenoid valve 241, and the metering bottle 21 and the liquid inlet 222 are respectively located on both sides of the protrusion 221.

[0063] The protrusion 221 is used to elevate the solenoid valve 241, facilitating its installation and fixation. The solenoid valve 241 includes a two-position two-way solenoid valve 241. When the two-position two-way solenoid valve 241 is closed, it can detect the liquid level and tilt of the measuring bottle 21. When the two-position two-way solenoid valve 241 is open, the liquid in the measuring bottle 21 can enter the collection bottle 22 through the suction pipe 24.

[0064] refer to Figure 5 The solenoid valve 241 is positioned close to the metering bottle 21, meaning the gap between them is small. This design helps to prevent liquid from stagnating in the suction line 24 between the solenoid valve 241 and the metering bottle 21, thereby ensuring the accuracy of liquid level monitoring.

[0065] like Figures 1 to 3 As shown, the lower ends of the two side plates 12 and 13 are respectively provided with grooves 121, which engage with the protrusions 221. The grooves 121 are used to avoid the protrusions 221 so that the lower ends of the two side plates 12 and 13 abut against the upper surface of the liquid collection bottle 22.

[0066] like Figure 1 , Figure 4 and Figure 5 As shown, the bottle body 2 also includes:

[0067] A water-sealed bottle 23 is disposed on one side of the liquid collection bottle 22;

[0068] An exhaust pipe 25 is connected between the water seal bottle 23 and the metering bottle 21.

[0069] The water seal bottle 23 is connected to the right side of the liquid collection bottle 22, and the two can be connected as a single unit. The upper surface of the water seal bottle 23 is provided with an air inlet 231, and the upper surface of the metering bottle 21 is provided with an exhaust port 212. The exhaust pipe 25 is connected between the air inlet 213 and the exhaust port 212.

[0070] Furthermore, the height of the upper surface of the water seal bottle 23 is higher than the height of the upper surface of the liquid accumulation bottle 22. After the monitoring device 1 is installed on the upper surface of the liquid accumulation bottle 22, the portion of the water seal bottle 23 protruding from the upper surface of the liquid accumulation bottle 22 is located on the right side of the monitoring device 1.

[0071] The water-seal bottle 23 is used to balance pressure, that is, to regulate and stabilize the pressure within the pleural cavity to ensure the patient's safety and comfort. By balancing the pressure within the pleural cavity, the water-seal bottle 23 facilitates the smooth flow of fluid from the pleural cavity into the measuring bottle 21. The water-seal bottle 23 contains a certain amount of water, which forms a water-seal system.

[0072] In a preferred embodiment, the exhaust pipe 25 is configured as a handle located above the water seal bottle 23 and the metering bottle 21, respectively. The exhaust pipe 25 is connected and fixed to the air inlet 213 and the exhaust outlet 212 to ensure the stability of the exhaust pipe 25 as a handle. Furthermore, the exhaust pipe 25 is detachable from both the air inlet 213 and the exhaust outlet 212, facilitating the initial placement of the monitoring device 1 on the upper surface of the liquid collection bottle 22, followed by the arrangement of the exhaust pipe 25 above the monitoring device 1. Simultaneously, the bottle body 2 can be used only once. By detachably connecting the exhaust pipe 25 to the air inlet 213 and the exhaust outlet 212, the monitoring device 1 can be reused and assembled with different bottle bodies 2.

[0073] like Figure 1 , Figure 4 and Figure 5 As shown, a drainage port 211 is provided on the upper surface of the measuring bottle 21, and the drainage port 211 is used to connect the thoracic drainage tube.

[0074] The pleural effusion is drained into a measuring bottle 21 via a chest drainage tube, allowing for the measurement of the drainage rate. When the fluid level in the measuring bottle 21 reaches a certain height, a solenoid valve 241 opens, allowing the fluid in the measuring bottle 21 to drain through the suction tube 24 into a storage container 22. The measuring bottle 21 is connected to a water-seal bottle 23 via an exhaust tube 25, using water pressure to balance the intrathoracic pressure, thus achieving the drainage purpose.

[0075] The assembly method of the body fluid drainage meter is as follows:

[0076] By aligning the first recess 14 of the monitoring device 1 with the metering bottle 21 of the bottle body 2, and aligning the second recess 15 of the monitoring device 1 with the solenoid valve 241 of the bottle body 2, the monitoring device 1 is installed on the liquid collection bottle 22 of the bottle body 2. At this time, the metering bottle 21 is located in the first recess 14, and the solenoid valve 241 is hidden in the second recess 15.

[0077] The exhaust pipe 25 is connected between the water seal bottle 23 and the metering bottle 21, at which point the exhaust pipe 25 is located above the monitoring device 1.

[0078] During disassembly, first remove the exhaust pipe 25, and then remove the monitoring device 1.

[0079] In summary, the monitoring device 1 and the bottle 2 are detachably connected, thus allowing the relatively expensive monitoring device 1 to be reused. The metering bottle 21 is used to receive fluid drained from the pleural cavity. Since the metering bottle 21 is engaged between the two side plates 12 and 13, the liquid level sensor group 141 on the inner walls of the two side plates 12 and 13 can be used to monitor the liquid level and overall tilt of the metering bottle 21 in real time. This design replaces the existing manual observation method, achieving real-time monitoring and significantly improving the monitoring effect and intelligence. Furthermore, by combining the liquid level sensor group 141 with monitoring the liquid level changes in the metering bottle 21 at different time periods, the drainage rate can be monitored.

[0080] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
