Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a medical electrode fluid flow monitoring device. Background Art

[0002] In the vast field of biological therapy, real-time monitoring of organisms is a crucial link. Fluid flow monitoring, as a common monitoring method in the medical field, is widely used in various scenarios, such as precise control of injection volume, continuous observation of gastric tube drainage volume, and dynamic monitoring of urine flow. In order to achieve these functions, medical professionals will use special monitoring devices to accurately detect fluid flow. These devices can not only reflect the dynamic changes of fluids in the body in real time, but also provide doctors with key clinical data, thereby helping them make more accurate and timely diagnosis and treatment decisions. By continuously optimizing and innovating the design and technology of monitoring devices, we can further improve the safety and effectiveness of biological therapy and bring better treatment effects and quality of life to patients.

[0003] Currently, although there are many monitoring devices on the market for measuring fluid flow, in actual application, these devices often find it difficult to achieve a high degree of accuracy when measuring fluid flow.

The presence of bubbles can interfere with the contact between the electrode and the fluid, causing the electrode to be unable to accurately capture the flow signal of the fluid, while particulate impurities may adhere to the surface of the electrode, changing the sensitivity and response characteristics of the electrode.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0038] Embodiment 1:

[0039] See also Figures 1 to 8 As shown, a medical electrode fluid flow monitoring device comprises:

[0040] Lined pipe 1;

[0041] Pretreatment mechanism 2, the pretreatment mechanism 2 includes a pretreatment tube 21, a filtering mechanism 22, a microporous membrane 23, a stabilizing cylinder 24, a second flange 25 and a second sealing groove 26. The pretreatment tube 21 is installed at one end of the lining pipe 1. Three filtering mechanisms 22 are provided, and the three filtering mechanisms 22 are all installed on one side of the inner wall of the pretreatment tube 21. The microporous membrane 23 is installed in the middle of the inner wall of the pretreatment tube 21. The stabilizing cylinder 24 is installed on the other side of the inner wall of the pretreatment tube 21. Two second flanges 25 and two second sealing grooves 26 are provided. The two second flanges 25 are respectively installed on both sides of the outer surface of the pretreatment tube 21, and the two second sealing grooves 26 are respectively opened at both ends of the pretreatment tube 21;

[0042] A connecting mechanism 3, wherein two connecting mechanisms 3 are provided, and the two connecting mechanisms 3 are respectively installed at the other end of the lining pipe 1 and the other end of the pretreatment mechanism 2, and the connecting mechanism 3 can realize the connection between the monitoring device and the medical pipe;

[0043] The mounting mechanism 4 is mounted at the bottom end of the lining pipe 1, and the mounting mechanism 4 can realize the rapid installation and disassembly of the monitoring device.

[0044] Depend on Figures 1 to 5 It can be seen that a coil 5 is installed in the middle of the outer surface of the lined pipe 1, a converter 6 is installed at the top of the coil 5, a display screen 7 is installed on the outer wall of the converter 6, first flanges 8 are installed on both sides of the outer surface of the lined pipe 1, a first sealing ring 10 is installed at one end of the lined pipe 1, a first sealing groove 9 is opened at the other end of the lined pipe 1, and a detection electrode 11 is arranged in the middle of the inner wall of the lined pipe 1;

[0045] The filtering mechanism 22 includes a fixing frame 221, a spiral bar 222, a filter screen 223 and a fixing block 224. The fixing frame 221 is installed on the inner wall of the pretreatment tube 21, the spiral bar 222 is installed on the outer surface of the fixing frame 221, two filter screens 223 are provided, and both filter screens 223 are installed on the inner wall of the fixing frame 221, and the fixing block 224 is installed in the middle of one end of the fixing frame 221.

[0046] As can be seen from the above, before monitoring the flow rate of the fluid, the fluid first flows into the pretreatment tube 21, and then passes through the filter screens 223 set on the three filter mechanisms 22, which can filter particles and impurities in the fluid step by step, and then further remove bubbles in the fluid through the microporous membrane 23 to ensure the purity of the fluid. This treatment process effectively avoids the interference of impurities and bubbles on the contact between the detection electrode 11 and the fluid, thereby improving the sensitivity and response characteristics of the detection electrode 11. The conical design of the stabilizing tube 24 realizes the stable flow of the fluid, so that the detection electrode 11 can achieve a high degree of precision and accuracy when monitoring the fluid. When the pretreated and stable-flowing fluid flows When it reaches the interior of the lined pipe 1, the detection electrode 11 arranged inside can monitor the data of the fluid in real time, and transmit the monitored data to the converter 6, so that after the converter 6 calculates and processes the data, the flow data of the fluid is displayed through the display screen 7. When it is necessary to clean the filter screen 223, the connecting mechanism 3 on the pretreatment tube 21 can be removed first, and then the fixing block 224 is held to drive the fixing frame 221 to rotate, so that the filter mechanism 22 can be removed from the interior of the pretreatment tube 21, so as to facilitate the cleaning or replacement of the filter screen 223 thereon, and also facilitate the cleaning of the microporous membrane 23 and the stabilizing cylinder 24, thereby further enhancing the pretreatment effect of the fluid.

[0047] Specifically, refer to Figures 1 to 5 As shown, the fixing frame 221 is configured as a circular frame with vertical rods, multiple anti-slip grooves are provided on the outer walls of both sides of the fixing block 224, a spiral groove matching the spiral strip 222 is provided on one side of the inner wall of the pretreatment tube 21, the mesh diameters of the filter screens 223 on the three filter mechanisms 22 decrease successively from left to right, and the stabilizing cylinder 24 is configured as a conical structure.

[0048] As can be seen from the above, the fixing frame 221 provides stable support for the filter screen 223 and ensures that it can be firmly fixed in the pretreatment pipe 21. The anti-slip groove can increase the friction of the outer surface of the fixing block 224. The spiral groove can facilitate the disassembly, replacement or cleaning of the filter mechanism 22, so that the three filter mechanisms 22 can filter particles and impurities in the fluid step by step to ensure the purity of the fluid. The conical stabilizing cylinder 24 further stabilizes and buffers the pretreated fluid to ensure that the fluid is in a stable state before entering the monitoring area.

[0049] Embodiment 2:

[0050] refer to Figure 6 and Figure 7 As shown, the connection mechanism 3 includes a mounting tube 31, a third flange 32, a second sealing ring 33, a first connector 34, a second connector 35, a third connector 36 and a fourth connector 37. The mounting tube 31 is mounted at one end of the pretreatment pipeline 21, the third flange 32 is mounted on the outer surface of the mounting tube 31, the second sealing ring 33 is mounted at one end of the mounting tube 31, the first connector 34 is mounted on the outer surface of the mounting tube 31, the second connector 35 is mounted on the outer surface of the first connector 34, the third connector 36 is mounted on the outer surface of the second connector 35, and the fourth connector 37 is mounted on the outer surface of the third connector 36;

[0051] The first connecting head 34 includes a connecting tube 341, a connecting screw 342, a third sealing ring 343 and a connecting screw groove 344. The connecting tube 341 is installed on the outer surface of the mounting tube 31, the connecting screw 342 is installed on one side of the outer surface of the connecting tube 341, the third sealing ring 343 is installed on the inner wall of the connecting tube 341, and the connecting screw groove 344 is opened on the other side of the inner wall of the connecting tube 341.

[0052] As can be seen from the above, firstly, the third flange 32 is connected to the second flange 25 by the screw and the nut, so as to realize the firm connection between the connection mechanism 3 and the pretreatment mechanism 2, and the second sealing ring 33 is tightly inserted into the second sealing groove 26, thereby significantly improving the sealing of the connection. At this time, by setting a plurality of connectors of different sizes and utilizing the connecting screw strips 342 and the connecting screw grooves 344 provided on the connecting tube 341, it is convenient to firmly connect these connectors with the medical pipelines matched thereto. At the same time, the addition of the third sealing ring 343 further strengthens the sealing performance of the connection between the connector and the medical pipeline, effectively avoiding the flow. This design enables the monitoring device to flexibly adapt to medical tubes of different diameters, thereby facilitating real-time monitoring of fluids in tubes of different diameters. This feature greatly meets the needs of various medical scenarios and effectively expands the scope of application of the monitoring device. In addition, the multiple anti-slip strips on the connecting tube 341 facilitate its rotation, which is beneficial to the rapid disassembly of the connecting tube 341. Moreover, by replacing connectors of different sizes, the connection between the medical tube and the matching connector can be easily achieved, thereby facilitating the maintenance and cleaning of the connecting mechanism 3 and the medical tube, thereby improving the reliability and service life of the overall equipment.

[0053] Preferably, reference Figure 6 and Figure 7As shown, the connecting tube 341 and the mounting tube 31 are both configured as conical structures, and a plurality of anti-slip strips are installed on the other side of the outer surface of the connecting tube 341, and a convex strip matching the connecting screw groove 344 is opened on one side of the outer surface of the mounting tube 31. The overall structure of the first connecting head 34 is consistent with the overall structure of the second connecting head 35, the third connecting head 36 and the fourth connecting head 37, and the sizes of the first connecting head 34, the second connecting head 35, the third connecting head 36 and the fourth connecting head 37 are reduced successively.

[0054] As can be seen from the above, the tapered connecting tube 341 and the mounting tube 31 facilitate the connection of pipes or connectors of different sizes, increase the flexibility and adaptability of the connection, the anti-slip strip can increase the friction on the outer surface of the connecting tube 341, and the convex strip is conducive to the connection between the mounting tube 31 and the first connector 34 or the medical pipeline. By providing connectors of various sizes, it can adapt to medical pipelines of different diameters, and is also conducive to the installation and disassembly of the connector.

[0055] Embodiment three:

[0056] refer to Figure 8 As shown, the mounting mechanism 4 includes a mounting frame 41, a forward and reverse screw rod 42, a limit rod 43, a mounting clamp plate 44 and a fixed clamp groove 45. There are two mounting frames 41, two mounting clamp plates 44 and two fixed clamp grooves 45, and the two mounting frames 41 are both installed at the bottom end of the lining pipe 1. The forward and reverse screw rods 42 are installed between the inner walls of both sides of the mounting frame 41 on one side through bearings, and the limit rod 43 is installed between the inner walls of both sides of the mounting frame 41 on the other side. The two mounting clamp plates 44 are both installed on the outer surfaces of the forward and reverse screw rods 42 and the limit rod 43, and the two fixed clamp grooves 45 are respectively opened at the lower parts of the opposite surfaces of the two mounting clamp plates 44.

[0057] As can be seen from the above, after the monitoring device is connected to the medical pipeline, the mounting mechanism 4 can be mounted on the bed frame or the frame of other medical equipment. The two mounting frames 41 can ensure that the mounting mechanism 4 and the lining pipe 1 are firmly installed. Subsequently, by rotating the adjustment handles on the forward and reverse screw rods 42, the two mounting clamps 44 on the forward and reverse screw rods 42 can be driven to move toward the middle. The limit rods 43 guide and limit the two mounting clamps 44, thereby improving their stability during movement, until the V-shaped structure fixing grooves 45 on the mounting clamps 44 tightly clamp the frame. This V-shaped structure not only provides a stable clamping point, but also can adapt to frames of different shapes and sizes. In this way, the monitoring device can be installed quickly and stably, and it is also convenient for subsequent quick disassembly. This design reduces the operating difficulty when installing the monitoring device and effectively improves the work efficiency of medical staff.

[0058] Preferably, reference Figure 8As shown, the top of the mounting frame 41 is configured as an arc-shaped frame body, the mounting clamping plate 44 is configured as a convex structure, and the fixing clamping groove 45 is configured as a V-shaped structure.

[0059] As can be seen from the above, the contact area between the mounting frame 41 and the lining pipe 1 can be increased, and the stability of the installation can be improved. The convex mounting clamp 44 is conducive to its movement and limiting. The V-shaped fixing clamp groove 45 provides a stable clamping point for the mounting clamp 44 and adapts to components of different shapes and sizes, ensuring the stability and accuracy of the clamping.

[0060] Application examples:

[0061] This design is mainly used for fluid flow monitoring in medical environments, especially in those occasions where accurate measurement of fluid flow is required and the fluid may contain particles or bubbles, such as operating rooms, intensive care units (I CU), hemodialysis rooms and other medical scenarios; This design proposes a medical electrode fluid flow monitoring device, which monitors the fluid flow by setting a detection electrode 11 inside the lining pipe 1 and using the resistance change or capacitance change between the detection electrodes 11. When the fluid flows, the resistance or capacitance value between the electrodes will change, so that the fluid flow can be calculated. Accurate flow monitoring helps medical staff to better control the drug administration speed and dosage, reduce medical risks, and improve patient safety and comfort; Before the fluid enters the lining pipe 1, it first enters the pretreatment mechanism 2, which is set inside the pretreatment mechanism 2 The filtering mechanism 22 and the microporous membrane 23 can effectively remove particles and bubbles in the fluid to ensure the purity and stable flow of the fluid. At the same time, the stabilizing cylinder 24 in the pretreatment mechanism 2 further ensures the stable flow of the fluid, thereby improving the precision and accuracy of the monitoring of the detection electrode 11. In addition, the design also provides a connecting mechanism 3, so that the monitoring device can adapt to medical pipes of different diameters, achieve wide applicability, and meet the needs of various medical scenarios. Through the installation mechanism 4, medical staff can quickly and easily install and disassemble the monitoring device, which reduces the difficulty of operation and time cost and improves work efficiency.
