[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0034] Currently, commonly used drainage devices, such as drainage catheters and drainage bags, usually rely on medical staff to observe the drainage situation at regular intervals. This method depends on medical staff to check and record regularly and periodically assess the drainage volume, which increases the workload of medical staff and may also lead to omissions or errors in recording, resulting in poor accuracy of drainage information statistics, which in turn affects the doctor's judgment and treatment of the condition.
[0035] For the reasons mentioned above, please refer to Figure 1 This embodiment provides a drainage monitoring system 200 that can record and provide feedback on drainage information, thereby enabling medical staff to accurately and promptly understand the drainage information, and thus improving medical efficiency and safety while reducing the workload of medical staff.
[0036] It should be noted that the drainage monitoring system 200 can be applied to various postoperative drainage procedures, such as abdominal surgery, thoracic surgery, amputation surgery, and intracranial surgery.
[0037] For details, please refer to Figures 1-5The drainage monitoring system 200 includes a monitoring component 210 and a drainage monitoring device 100. The monitoring component 210 can be a monitoring instrument in the prior art, which can receive and record the flow data monitored by the drainage monitoring device 100, perform statistical analysis based on the flow data, and store, transmit and display the relevant data to the backend, thereby facilitating medical staff to monitor the drainage situation conveniently and in a timely manner.
[0038] The drainage monitoring device 100 includes a drainage tube 110, a drainage bottle 120, a liquid level detector 130, a collection bottle 140, a guide tube 150, and an on / off control element 160. The drainage tube 110 is connected to the drainage bottle 120, and the drainage bottle 120 is used to collect or transfer the liquid drained through the drainage tube 110. The liquid level detector 130 is connected to the drainage bottle 120 and is used to detect the liquid level in the drainage bottle 120. The collection bottle 140 is connected to the drainage bottle 120 through the guide tube 150, and the collection bottle 140 is used to receive the liquid discharged from the drainage bottle 120. The on / off control element 160 is connected to the guide tube 150 and is used to connect or disconnect the drainage bottle 120 and the guide tube 150.
[0039] Based on the above-mentioned flow monitoring device 100, by electrically connecting the monitoring component 210 with the liquid level detector 130 and the on / off control component 160, the monitoring component 210 can receive the flow monitoring data output by the liquid level detector 130, thereby enabling the monitoring component 210 to analyze the received relevant data and control the on / off control component 160 based on the data.
[0040] In this drainage monitoring system 200, the outlet end of the drainage tube 110 is connected to the drainage bottle 120 for drainage. During the drainage process, the drained liquid enters the drainage bottle 120. The liquid level detector 130 monitors the amount of drained liquid in the drainage bottle 120, thus obtaining real-time drainage data. By monitoring the liquid level in the drainage bottle 120, when the liquid level reaches a certain level, the on / off control device 160 connects the collection bottle 140 to the drainage bottle 120, thereby enabling... The liquid in the drainage bottle 120 can be introduced into the collection bottle 140 for collection. During this process, the drainage bottle 120 can be connected to the collection bottle 140 after its liquid level reaches a certain value, or it can be kept in a constant state of connection with the collection bottle 140. The connection state between the collection bottle 140 and the drainage bottle 120 can be adjusted based on a preset monitoring method. Thus, by setting it up in this way, the drainage bottle 120 can not only facilitate the liquid level detector 130 to calculate the drainage volume, but also serve as a temporary storage, collection or transfer point for the drainage liquid.
[0041] Based on the above structure, by electrically connecting the monitoring component 210 with the liquid level detector 130 and the on / off control component 160, the monitoring component 210 can perform statistical analysis based on the collected flow data, thereby enabling medical staff to accurately and timely understand the drainage information, thus reducing the workload of medical staff while improving medical efficiency and safety.
[0042] Further, please refer to Figures 1-5 In this embodiment, to facilitate monitoring of the liquid level within the drainage bottle 120, a float plate 121 can be installed inside the drainage bottle 120. A liquid level detector 130 is used to sense the position of the float plate 121 to measure the liquid level in the drainage bottle 120. That is, in this way, the liquid level detector 130 can sense the relative position change of the float plate 121 within the drainage bottle 120 over a fixed time period (e.g., 1 minute, 5 minutes, 10 minutes, etc.), thereby measuring the drainage rate.
[0043] Furthermore, when configuring the liquid level detector 130, the liquid level detector 130 may include, but is not limited to, an infrared liquid level sensor that is in close contact with the drainage bottle 120, an ultrasonic liquid level sensor connected to the drainage bottle 120, a pressure-type liquid level sensor that extends into the drainage bottle 120, or a capacitive liquid level sensor that is in close contact with the drainage bottle 120. The specific type selected can be adapted to meet the needs of use.
[0044] To facilitate the placement and installation of the aforementioned structures during the drainage process, the drainage monitoring device 100 includes a drainage box 170; the drainage bottle 120, liquid level detector 130, on / off control component 160, and flow rate control component 180 are all disposed within the drainage box 170; the collection bottle 140 is located outside the drainage box 170; that is, by setting the drainage box 170, the drainage monitoring system 200 can be divided into three parts: monitoring component 210, drainage box 170, and collection bottle 140. This arrangement facilitates placement during use; and based on convenient placement, by extending one end of the drainage tube 110 and the guide tube 150 into the drainage box 170 and communicating with the drainage bottle 120, drainage and drainage monitoring can be performed.
[0045] It should be noted that when connecting the drainage tube 110 and the guide tube 150 to the drainage bottle 120, the drainage tube 110 and the guide tube 150 are connected to the two ends of the drainage bottle 120 respectively. Moreover, when the drainage box 170 is placed normally, the drainage tube 110 is connected to the upper end of the drainage bottle 120, while the guide tube 150 is connected to the lower end of the drainage bottle 120.
[0046] Based on the above, please refer to Figures 1-5In this embodiment, the on / off control component 160 controls the flow between the drainage bottle 120 and the collection bottle 140. This configuration allows the liquid in the drainage bottle 120 to be directed to the collection bottle 140 for collection based on changes in its internal liquid level. The on / off control component 160 can be configured as a first electric regulating valve 161, which controls the flow between the drainage bottle 120 and the collection bottle 140 based on the control of the monitoring component 210. Alternatively, the on / off control component 160 can include a first push rod motor 162, a first clamping member 163, and a second clamping member 164. The first clamping member 163 and the second clamping member 164 are distributed on both sides of the guide tube 150, and the first clamping member 163 is connected to the first push rod motor 162. The first push rod motor 162 drives the first clamping member 163 to move relative to the second clamping member 164 to clamp or release the guide tube 150. Thus, in this way, the monitoring component 210 controls the first push rod motor 162 to adjust the clamping force of the first clamping member 163 and the second clamping member 164 on the guide tube 150, thereby causing the inner cavity of the guide tube to be completely closed or not closed, thereby realizing the on / off control of the drainage bottle 120 and the collection bottle 140. It should be noted that the first clamping member 163 and the second clamping member 164 can not only realize the on / off control, but also control the flow rate of the guide tube 150.
[0047] Further, please refer to Figures 1-5 In this embodiment, based on the above structure, in order to control the conduction state and flow rate of the drainage tube 110 during use, the drainage monitoring device 100 further includes a flow rate control component 180. The flow rate control component 180 is connected to the drainage tube 110 and is used to adjust the flow rate of the drainage tube 110. The flow rate control component 180 is electrically connected to the monitoring component 210, thereby enabling the drainage rate of the drainage tube 150 to be appropriately adjusted according to the drainage speed set by the user in the drainage monitoring system 200.
[0048] The flow rate control component 180 operates on a similar principle to the on / off control component 160 described above. The difference lies in that the flow rate control component 180 requires not only on / off control but also adjustment of the flow rate. Therefore, the flow rate control component 180 may include a second electric regulating valve 181. In addition, the flow rate control component 180 may also include a second push rod motor 182, a third clamping component 183, and a fourth clamping component 184. The third clamping component 183 and the fourth clamping component 184 are distributed on both sides of the drainage tube 110, and the third clamping component 183 is connected to the second push rod motor 182. The second push rod motor 182 drives the third clamping component 183 to move relative to the fourth clamping component 184 to clamp or release the drainage tube 110. The specific working principle will not be elaborated here.
[0049] Please refer to Figures 1-5 The principle of this drainage monitoring system 200 is as follows:
[0050] The drainage fluid accumulates in the drainage bottle 120. At fixed intervals (e.g., 1 minute, 5 minutes, or 10 minutes), the level detector 130 measures the liquid level or the position of the floatable plate 121 in the drainage bottle 120 and sends the measurement data to the monitoring component 210. The monitoring component 210 calculates and displays the increase in drainage fluid volume within the fixed time interval based on the parameters of the drainage bottle 120. If the drainage volume is greater than the value set by the user in the monitoring component 210, the monitoring component 210 issues a command to adjust the degree of closure of the drainage tube by the flow rate control component 180; if the drainage volume is less than the value set by the user in the monitoring component 210, the flow rate control component 180 is adjusted to the degree of opening of the drainage tube; this adjustment continues until the increase in liquid volume in the drainage bottle 120 per unit time equals the value set by the user, at which point the flow rate control component 180 maintains this state. If a new increase in liquid volume in the drainage bottle 120 per unit time does not equal the value set by the user, a new closed-loop adjustment is restarted.
[0051] When the level of the drainage fluid or the floating plate approaches the top of the drainage bottle 120, the monitoring component 210 controls the on / off control component 160 to open the guide tube 150, so that all the liquid in the drainage bottle 120 flows into the waste liquid collection bottle. Then, the monitoring component 210 controls the on / off control component 160 to close again and restart the above closed-loop adjustment.
[0052] Based on the above, please refer to Figures 1-5 The workflow of the drainage monitoring system 200 is as follows:
[0053] After the drainage tube 110 is connected to the drainage site, the drainage fluid enters the drainage bottle 120 through the drainage tube 110. The monitoring component 210 controls the on / off controller to disconnect the drainage bottle 120 from the collection bottle 140 and records the disconnection time, liquid level position or float position H1.
[0054] Subsequently, the drainage fluid accumulates in the drainage bottle 120. The monitoring component 210 controls the liquid level detector 130 to measure the liquid level or float position H2 at its built-in fixed time intervals (e.g., 1 minute, 5 minutes, or 10 minutes). Based on the liquid level change (H2-H1) and its built-in drainage bottle parameters, the monitoring component 210 can calculate the drainage rate within the fixed time interval. When the liquid level reaches the highest predetermined height, the monitoring component 210 controls the on / off controller to connect the drainage bottle 120 and the collection bottle 140, allowing all the liquid in the drainage bottle 120 to flow into the collection bottle 140. Then, the monitoring component 210 controls the on / off controller to disconnect the drainage bottle 120 and the collection bottle 140, and then closes them again, recording the time and liquid level or float position.
[0055] It should be noted that, firstly, the relevant data and status information in the aforementioned process can all be displayed on the monitor by the monitoring component 210;
[0056] Secondly, the drainage bottle 120 has a regular shape, such as a cylinder or cuboid. After the drainage tube 110 is fixed, the bottom area of the drainage bottle 120 can be fixed and set in the monitoring component 210. After the guide tube 150 is closed by the on / off control component 160, the change in the liquid height entering the drainage bottle 120 within a certain period of time can be measured by the liquid level detector 130. Then, the outflow volume of the drainage fluid during that period can be calculated. The drainage rate can be presented to medical staff intuitively in volume / time format (such as mL / h) without the need to measure and input the drainage fluid density. Medical staff can input the required drainage rate in the monitoring component 210. The flow rate control device adjusts the size of the conduction area of the drainage tube 110 according to the flow rate measured by the monitoring component 210. Thus, the drainage monitoring system 200 can achieve the predetermined drainage rate through a measurement-control-measurement-control method.
[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
