Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a weight-sensing automatically liftable drainage tube adjusting device and a control method therefor. Background Art

[0002] Drainage is the use of a drainage tube to remove abnormal liquid substances from the human body, such as gas, exudate, blood, pus, etc., to prevent the accumulation of these useless body fluids in tissues or body cavities, thereby removing the bacterial culture medium, preventing infection, and reducing local pressure, which is beneficial to wound healing. Through drainage, abnormal liquids in the body can be removed, the environment for bacterial growth can be reduced, and the risk of infection can be lowered.

[0003] Currently, drainage is not just simply removing the liquid in the body. Many clinical patients have special drainage tubes that require precise control of the drainage volume, and even different drainage volumes are required over time. However, after adjusting the height of the drainage tube clinically, due to factors such as the change of the patient's body position, turning over, back patting, coughing, and some operations, the drainage volume cannot be precisely controlled, and adaptive adjustment cannot be achieved. Medical staff need to manually adjust the position, but the patient's body position changes at any time, and it is very difficult for medical staff to adjust at any time, which cannot meet the drainage needs of patients; at the same time, current drainage bags or drainage bottles are generally hung directly beside the bed by hanging or pasted by tape, and cannot be directly clamped and fixed, and there are still defects to a certain extent.

[0004] Therefore, a weight-sensing automatically liftable drainage tube adjusting device is needed to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention discloses a weight-sensing automatically liftable drainage tube adjusting device, comprising: a clamping device and a supporting vertical plate; a limiting groove is provided at the upper end of the clamping device, and the supporting vertical plate is fixedly installed on the limiting groove through bolts. An extension plate is vertically and fixedly installed on the side wall of the lower end of the supporting vertical plate, and a fixing block is vertically and fixedly installed on the side wall of the upper end of the supporting vertical plate. A transmission component is movably installed between the extension plate and the fixing block. A slider is movably installed on the transmission component. A limiting block is vertically installed at the lower end of the slider, and a U-shaped groove is provided on the limiting block to limit the drainage tube through the U-shaped groove; a hook is fixedly installed at the upper end of the slider, and a pressure sensor is installed on the hook; a lower travel switch is fixedly arranged in the middle of the extension plate, and an upper travel switch is fixedly installed on the upper end of the supporting vertical plate, on one side of the fixing block; the up and down movement of the slider is controlled by controlling the rotation of the transmission component to control the up and down position of the drainage bag;

[0006] Further, the clamping device includes a support housing, a rotating knob, a clamping rod, and a ejector rod; circular grooves are perpendicularly formed on the support housing, the ejector rod is movably installed on one circular groove, the rotating knob is installed on the other circular groove through threaded connection, a top head is rotatably installed at the end of the rotating knob, and the contact surfaces of the top head and the ejector rod are both wedge-shaped structures and are in contact with each other; a support block is fixedly installed on the side wall of the support housing perpendicular to the circular groove, the clamping rod is movably installed on the support block, the upper end of the clamping rod extends onto the ejector rod, the other end extends to the outside of the support and a clamping head is fixedly installed at the end, and another clamping head is provided on the support housing corresponding to the clamping head on the clamping rod; by rotating and controlling the forward or reverse rotation of the rotating knob to control the expansion and contraction of the ejector rod, and further controlling the rotation of the clamping rod, the clamping heads approach each other to achieve the clamping effect;

[0007] Further, the transmission component includes: a screw rod and a motor, the motor is installed at the lower end of the extension plate, the screw rod is fixedly installed on the output shaft of the motor, and the other end of the screw rod is rotatably installed on the fixed block;

[0008] Further, at the position of the slider corresponding to the hook, a groove is formed in the middle, a fixing belt is fixedly installed on one side of the groove, and a magic tape is fixedly installed on the other side;

[0009] Further, rollers are rotatably installed at positions along the U-shaped curve on the U-shaped groove.

[0010] In addition, the present invention discloses a control method for a weight-sensing and automatically liftable drainage tube adjusting device, which specifically includes the following steps:

[0011] S1: Fix the drainage tube through the U-shaped groove. Hang the drainage bag or drainage bottle on the hook and connect the pressure sensor to the drainage bag to detect the pressure in the drainage bag through the pressure sensor;

[0012] S2: The pressure sensor feeds back the signal to the control center, and the control center controls the forward or reverse rotation of the motor according to the preset instructions for adjustment to enable adaptive adjustment;

[0013] S3: When the slider moves up or down to the lower travel switch or the upper travel switch, the motor stops rotating and the control center gives an alarm. At this time, it is processed by medical staff, and after the processing is completed and reset, it can be used continuously;

[0014] Further, the preset instructions in S2 are:

[0015] S2.1: Set the required flow rate of drainage through the control center, denoted as V; the pressures (pressures) in the pipes of the U-shaped groove are denoted as P respectively. The relationship between the flow rate and the pressure is that when the pipe diameter remains unchanged, the greater the pressure P, the greater the flow rate V; the smaller the pressure P, the smaller the flow rate V.

[0016] S2.2: Detect the pressure in the pipe by the pressure sensor and make a judgment according to the magnitude relationship of the pressure. If the pressure P in the pipe is greater than 0, the motor needs to rotate forward to adjust the slider upward to reduce the flow rate. When the pressure P in the pipe is less than 0, the motor needs to rotate in reverse to adjust the slider downward to increase the flow rate.

[0017] The beneficial effects of the present invention are:

Detailed implementation mode

[0030] Embodiment 1

[0031] A weight-sensing automatic lifting drainage tube adjusting device, comprising: a clamping device 1 and a supporting vertical plate 2; a limiting groove 14 is opened at the upper end of the clamping device 1, and the supporting vertical plate 2 is fixedly installed on the limiting groove 14 through a bolt 21. An extension plate 26 is vertically and fixedly installed on the lower side wall of the supporting vertical plate 2, and a fixed block 23 is vertically and fixedly installed on the upper side wall of the supporting vertical plate 2. A transmission assembly 22 is movably installed between the extension plate 26 and the fixed block 23. A slider 26 is movably installed on the transmission assembly 22. A limiting block 34 is vertically installed at the lower end of the slider 26. A U-shaped groove 341 is opened on the limiting block 34. The drainage tube is limited through the U-shaped groove 341. In addition, a roller 342 is rotatably installed at a position along the U-shaped curve on the U-shaped groove 341. By providing the roller 342, the limiting effect of the U-shaped groove 341 on the pipeline can be further reduced, enabling the pipeline to move smoothly, ensuring that the drainage tube will not be pulled out when the patient turns over or moves, and at the same time, the radian of the U-shaped groove 341 will directly determine the strength of the limiting effect on the drainage tube. In order to reduce this limiting effect, the radius of curvature of the U-shaped groove 341 needs to be set relatively large, making the movement of the drainage tube smoother; a hook 331 is fixedly installed at the upper end of the slider 26, and a pressure sensor 332 is installed on the hook 331; a lower travel switch 24 is fixedly arranged in the middle of the extension plate 26, and an upper travel switch 25 is fixedly installed on the upper end of the supporting vertical plate 2, on one side of the fixed block 23; the up and down movement of the slider 26 is controlled by controlling the rotation of the transmission assembly 22 to control the up and down position of the drainage bag; the clamping device 1 adopts an adjustable clamp arm structure, which can be tightly and stably clamped on the bedside, bracket or rod-shaped objects of various diameters, such as the armrest of a hospital bed, effectively replacing the traditional tape pasting method, reducing the irritation and discomfort of the patient's skin, and at the same time enhancing the stability and flexibility of the fixation.

[0032] Embodiment 2

[0033] In this embodiment, based on the clamping device 1 described in Embodiment 1, the clamping device 1 includes a support housing 17, a rotating knob 11, a clamping rod 13, and a push rod 16. Circular grooves 171 are perpendicularly formed on the support housing 17. The push rod 16 is movably installed in one circular groove 171, and the rotating knob 11 is installed through threaded connection in the other circular groove 171. A top head 111 is rotatably installed at the end of the rotating knob 11. The contact surfaces of the top head 111 and the push rod 16 are both wedge-shaped structures and are in contact with each other. A support block 15 is fixedly installed on the side wall of the support housing 17 perpendicular to the circular groove 171. The clamping rod 13 is movably installed on the support block 15. The upper end of the clamping rod 13 extends onto the push rod 16, and the other end extends to the outside of the support and a clamping head 12 is fixedly installed at the end. Another clamping head 12 is provided on the support housing 17 corresponding to the clamping head 12 on the clamping rod 13. By rotating and controlling the forward or reverse rotation of the rotating knob 11, the telescopic movement of the push rod 16 is controlled, and further the rotation of the clamping rod 13 is controlled, so that the clamping heads 12 approach each other to achieve the clamping function. Specifically, during use, when the surgical rotating knob 11 is rotated, the top head 111 will move upward under the drive of the rotating knob 11. At the same time, due to the inclined surface structure of the top head 111, the top head 111 will push the push rod 16 to move outward. The push rod 16 will contact the clamping rod 13 and gradually push the clamping rod 13. At the same time, the clamping rod 13 is rotatably connected to the support block 15, so the clamping head 12 at the end of the clamping rod 13 will gradually approach and form a clamping effect on the object to be clamped. At the same time, the setting of the thread enables it to clamp more firmly and will not move randomly, ensuring its stability.

[0034] Embodiment 3

[0035] In this embodiment, the transmission assembly 22 includes a screw rod 222 and a motor 231. The motor 231 is installed at the lower end of the extension plate 26. The screw rod 222 is fixedly installed on the output shaft of the motor 231. The other end of the screw rod 222 is rotatably installed on the fixed block 23. By rotating the motor 231 to drive the screw rod 222 to rotate, the up and down movement of the slider 26 is driven, serving as an execution element for adjustment. The transmission method of the cooperation of the motor 231, the screw rod 222, and the slider 26 belongs to the prior art and will not be described in detail here.

[0036] In addition, in this embodiment, based on the slider 26 described in Embodiment 1, at the position of the slider 26 corresponding to the hook 331, a groove 33 is provided in the middle. A fixing strap 31 is fixedly installed on one side of the groove 33, and a magic tape 32 is fixedly installed on the other side. The fixing strap 31 is used to further fix the drainage bag or drainage bottle hanging on the hook 331. At the same time, the installed magic tape 32 can make it be firmly fixed and convenient to disassemble. The body of the drainage bag or drainage bottle is relatively stable, and the pressure generated inside can be kept relatively stable, which can reduce the influence of shaking on the pressure detected by the sensor.

[0037] Embodiment 4

[0038] In this embodiment, the present invention discloses a control method for a weight-sensing and automatically liftable drainage tube adjusting device, which specifically includes the following steps:

[0039] S1: Fix the drainage tube through the U-shaped groove 341. Hang the drainage bag or drainage bottle on the hook 331 and connect the pressure sensor 332 to the drainage bag. Detect the pressure in the drainage bag through the pressure sensor 332. The pressure sensor 332 can be a rod-shaped pressure sensor 332 for monitoring the pressure (pressure) inside the pipeline. At the same time, the drainage bag or drainage tube should be a drainage bag or drainage tube with double joints, one for accessing the drainage fluid and the other for discharging the drainage fluid. The pressure sensor 332 can also be placed at the position of a suitable joint to enable it to be fixed inside or select a suitable joint for access. The joint belongs to the prior art and a three-way joint etc. can be used, and no more details will be given here.

[0040] S2: The pressure sensor 332 feeds back the signal to the control center, and the control center controls the forward or reverse rotation of the motor 231 according to the preset instructions to adjust it to be self-adaptive.

[0041] S3: When the slider 26 moves up or down to the lower travel switch 24 or the upper travel switch 25, the motor 231 stops rotating and the control center gives an alarm (the alarm device and the control center are not shown in the figure). At this time, the medical staff will handle it, and after the handling is completed and reset, it can be used continuously.

[0042] Further, the preset instructions in S2 are:

[0043] S2.1: Set the required drainage flow rate through the control center, denoted as V. The pressure (pressure) in the pipeline of the U-shaped groove 341 is denoted as P respectively. The relationship between the flow rate and the pressure is that when the pipeline diameter remains unchanged, the greater the pressure P, the greater the flow rate V; the smaller the pressure P, the smaller the flow rate V.

[0044] S2.2: The pressure sensor 332 detects the pressure in the pipeline at this time, and makes a judgment based on the magnitude relationship of the pressure. If the pressure P in the pipeline is greater than 0, the motor 231 needs to rotate forward to adjust the slider 26 upward to reduce the flow rate. When the pressure P in the pipeline is less than 0, the motor 231 needs to rotate reversely to adjust the slider 26 downward to increase the flow rate. It can achieve the maintenance of the flow rate, and can be adjusted in real time, effectively replacing the traditional manual adjustment form; by monitoring the pressure in the pipeline as feedback, the up and down movement of the slider 26 is adjusted through the transmission component 22, thereby maintaining the relative constancy of the flow rate during drainage, and the drainage speed of the patient at a certain stage can be maintained and the drainage speed will not be too fast or too slow due to the movement of the patient himself, ensuring the normal progress of drainage.
