Description

Technical Field

[0001] This invention relates to the field of medical supplies, and more particularly to a device for controlling the drainage speed of a lumbar cistern. Background Technology

[0002] Lumbar cistern drainage is a medical procedure that drains cerebrospinal fluid through the lumbar spine, and has the effect of reducing intracranial pressure. The drainage rate of lumbar cistern drainage should be strictly controlled according to the patient's condition, usually 2-4 drops per minute, with a drainage volume of about 12 mL per hour and a daily drainage volume of 150-300 mL.

[0003] Currently, hospitals typically control the drainage rate by manually observing the flow and adjusting the height of the drainage device accordingly. ZL202121414833.4 discloses an adjustable auxiliary frame for lumbar cistern drainage tubes, including a movable base with a vertically mounted guide rod. The guide rod has a vertically sliding mechanism that supports the lumbar cistern drainage tube at a specified height. The sliding mechanism includes a sliding frame fitted onto the guide rod, a fastening bolt on the right side of the sliding frame, and a drainage tube placement platform on the left side of the sliding frame, with a laser mounted on the side of the platform. This auxiliary frame allows for adjustment of the drainage tube height as needed, meeting specific height requirements and changing the existing fixing methods of bed rails or IV stands.

[0004] The above methods require constant manual monitoring of the drainage rate. If the rate is too fast, the drainage device is raised to increase the difficulty of cerebrospinal fluid drainage, thus slowing down the drainage speed. If the rate is too slow, the drainage device is raised to reduce the difficulty of drainage, thus accelerating the drainage process. Because this method requires constant manual monitoring and adjustment, it is cumbersome, labor-intensive, and prone to delays. Furthermore, even if the drainage device is adjusted to the appropriate height and the drainage rate meets requirements, this optimal state is difficult to maintain for long periods because the pressure of cerebrospinal fluid in the body is not constant, and changes in body position will also cause variations in the drainage rate, necessitating continued monitoring and adjustment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a lumbar cistern drainage speed control device that can accurately control the drainage speed and whose drainage speed does not change due to changes in the patient's condition.

[0006] The technical solution adopted to solve the above problems is: the lumbar sac drainage speed control device includes a guide plate, a drive plate, a drive shaft, a clamp, a drainage tube groove, a groove adjustment device, a motor, and a controller; The guide plate is vertically fixed and has a guide groove, including a vertically arranged straight guide groove; the drive shaft passes through the guide plate and is mounted on the guide plate; the motor is located behind the guide plate and connected to the drive shaft; the controller can control the motor speed; the drive plate is located in front of the guide plate, and the center of the drive plate is connected to the drive shaft; the drive plate has at least three radial elongated holes, and each radial elongated hole is evenly distributed around the drive shaft. The clamping device is set one-to-one with the radial elongated hole. The clamping device includes a circular slider, a connecting shaft and a clamping wheel.

[0011] Furthermore, the lumbar sac drainage rate control device includes a drainage device, which includes a drainage tube, a puncture needle, a drainage bag, a positioning flange, and a measuring cylinder. The puncture needle and the drainage bag are respectively connected to the two ends of the drainage tube. The positioning flange and the measuring cylinder are set on the drainage tube, with the positioning flange close to the puncture needle and the measuring cylinder close to the drainage bag.

[0012] Another technical solution to solve the above problems is: the lumbar sac drainage speed control device includes a drive disc, drive shaft, drive shaft seat, clamp, drainage tube groove, groove adjustment device, motor and controller; The drive shaft seat is fixedly installed; the drive shaft is horizontally installed and mounted on the drive shaft seat; the motor is located behind the drive shaft and connected to the drive shaft, and the controller can control the motor speed; the drive disc is located in front of the drive shaft, the center of the drive disc is connected to the drive shaft, and the drive disc has at least three radial guide holes, each radial guide hole being evenly distributed around the drive shaft as the center. The clamping device is set in a one-to-one correspondence with the radial guide hole. The clamping device includes a clamping rod, a clamping wheel and a spring. The clamping rod is inserted into the radial guide hole and cooperates with the radial guide hole. The drive disk restricts the rotation of the clamping rod and restricts the clamping rod from exiting the radial guide hole. The spring is located in the radial guide hole and pushes the clamping rod outward. The clamping wheel is connected to the clamping rod. The drainage pipe groove is set vertically and corresponds to the position of the drive disc; the clamping wheel can enter the drainage pipe groove and clamp the drainage pipe placed in the drainage pipe groove; during the operation of the waist pool drainage speed control device, at least one clamping device clamps the drainage pipe; the groove adjustment device can drive the drainage pipe groove to move left and right.

[0013] Furthermore, the trough adjustment device includes an adjustment device base, a connecting plate, a clamping knob, and two guide rods. The adjustment device base is fixedly installed, and the two guide rods are spaced apart in the vertical direction. The guide rods pass through the adjustment device base, and their two ends are connected to the drainage pipe trough and the connecting plate, respectively. The clamping knob passes through the connecting plate and is threadedly connected to the adjustment device base, and the clamping knob clamps the connecting plate.

[0014] Furthermore, the lumbar sac drainage speed control device includes a device box, which includes a box body and a cover on the front end of the box body; the drive disc, drive shaft, drive shaft seat, clamp, drainage tube groove, groove adjustment device, motor and controller are all located inside the device box; the upper and lower ends of the box body are provided with pipe passage grooves, and the positions of the pipe passage grooves correspond to the drainage tube grooves.

[0015] Furthermore, the lumbar sac drainage rate control device includes a drainage device, which includes a drainage tube, a puncture needle, a drainage bag, a positioning flange, and a measuring cylinder. The puncture needle and the drainage bag are respectively connected to the two ends of the drainage tube. The positioning flange and the measuring cylinder are located in the drainage tube, with the positioning flange close to the puncture needle and the measuring cylinder close to the drainage bag.

[0016] The beneficial effects of this invention are: Figure 5 When using the first scheme's lumbar cistern drainage speed control device to control the lumbar cistern drainage speed, the drainage tube of the drainage device is placed into the drainage tube groove. The motor starts, driving the drive disc to rotate. The drive disc drives the clamping device to move along the guide groove. When the clamping device is located in the guide straight groove, the clamping wheel enters the drainage tube groove and clamps the drainage tube. The clamping wheel of the clamping device in the guide straight groove clamps the drainage tube and moves downward. During this process, it squeezes the cerebrospinal fluid in the drainage tube downward. After the clamping wheel rolls over, the drainage tube rebounds, generating a certain negative pressure, which in turn acts as a suction effect, drawing the cerebrospinal fluid into the drainage tube.

[0017] Thus, during operation, this invention continuously repeats the action of compressing the drainage tube and squeezing cerebrospinal fluid downwards, while the drainage tube repeatedly rebounds to draw in cerebrospinal fluid, thereby achieving cerebrospinal fluid drainage. During this process, the drainage speed is related to the speed of the compressor's operation, but does not change due to variations in the patient's cerebrospinal fluid pressure or body position. Therefore, once the drainage speed is set, no further manual observation is required; the drainage speed remains constant, ensuring accuracy and facilitating cerebrospinal fluid drainage.

[0018] like Figure 9 As shown, the main working principle and effect of the lumbar cistern drainage speed control device in the second scheme are the same as those in the first scheme. It also has the beneficial effects of not needing to observe manually after the drainage speed is set, the drainage speed will not change, the drainage speed is accurate, and it facilitates the drainage of cerebrospinal fluid.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, the first type of lumbar sac drainage speed control device includes a guide plate 7, a drive plate 3a, a drive shaft 8, a clamping device 4a, a drainage pipe groove 5, a groove adjustment device 6, a motor 9, and a controller 2; The guide disk 7 is vertically fixed and has a guide groove 7-1, which includes a vertically arranged guide straight groove 7-1-1. The drive shaft 8 passes through the guide disk 7 and is mounted on the guide disk 7. The motor 9 is located behind the guide disk 7 and is connected to the drive shaft 8. The controller 2 can control the speed of the motor 9. The drive disk 3a is located in front of the guide disk 7. The center of the drive disk 3a is connected to the drive shaft 8. The drive disk 3a has at least three radial elongated holes 3a-1, which are evenly distributed around the drive shaft 8. The clamping device 4a is configured in a one-to-one correspondence with the radial elongated hole 3a-1. The clamping device 4a includes a circular slider 4a-1, a connecting shaft 4a-2, and a clamping wheel 4a-3. The circular slider 4a-1 is engaged with the guide groove 7-1. The connecting shaft 4a-2 passes through the radial elongated hole 3a-1 and is engaged with the radial elongated hole 3a-1. The connecting shaft 4a-2 is connected to the circular slider 4a-1. The clamping wheel 4a-3 is located in front of the drive disk 3a and is connected to the connecting shaft 4a-2. The drive disk 3a can drive the clamping device 4a to move along the guide groove 7-1. The drainage pipe groove 5 is set vertically; when the clamping device 4a is located in the guide straight groove 7-1-1, the clamping wheel 4a-3 enters the drainage pipe groove 5 and clamps the drainage pipe 11-1 placed in the drainage pipe groove 5; during the operation of the waist pool drainage speed control device, at least one clamping device 4a clamps the drainage pipe 11-1; the groove adjustment device 6 can drive the drainage pipe groove 5 to move left and right.

[0022] This invention can be used in conjunction with existing drainage devices for lumbar ventricle drainage. For example... Figure 5When controlling the lumbar cistern drainage speed using the first scheme's lumbar cistern drainage speed control device, the drainage tube 11-1 of the drainage device 11 is placed into the drainage tube groove 5. The motor 9 starts, driving the drive disc 3a to rotate. The drive disc 3a drives the clamping device 4a to move along the guide groove 7-1. When the clamping device 4a is located in the guide straight groove 7-1-1, the clamping wheel 4a-3 enters the drainage tube groove 5 and clamps the drainage tube 11-1. Inside the guide straight groove 7-1-1, the clamping wheel 4a-3 of the clamping device 4a clamps the drainage tube 11-1 and moves downwards. During this process, it squeezes the cerebrospinal fluid in the drainage tube 11-1 downwards. After the clamping wheel 4a-3 rolls past, the drainage tube 11-1 rebounds, generating a certain negative pressure, which in turn acts as a suction force, drawing the cerebrospinal fluid into the drainage tube 11-1.

[0023] Thus, during the operation of this invention, the action of repeatedly pressing the drainage tube 11-1 and squeezing the cerebrospinal fluid downwards, along with the continuous rebound of the drainage tube 11-1 to draw in cerebrospinal fluid, is repeated to achieve cerebrospinal fluid drainage. During this process, the drainage speed is related to the speed of movement of the clamping device 4a, and does not change due to changes in the patient's cerebrospinal fluid pressure or body position. Therefore, once the drainage speed is set, no further manual observation is required; the drainage speed remains constant, accurate, and facilitates cerebrospinal fluid drainage.

[0024] Because the guide groove 7-1 restricts the movement of the clamping device 4a, it can only move along the guide groove 7-1. During this movement, the distance between the clamping device 4a and the drive shaft 8 changes. Therefore, a radial elongated hole 3a-1 needs to be provided on the drive disc 3a. The guide groove 7-1 must be an annular groove, and the slider needs to be a circular slider 4a-1. Only a circular slider 4a-1 can pass through the non-linear part of the guide groove 7-1. The circular slider 4a-1 can rotate within the guide groove 7-1 without any adverse effects. The clamping wheel 4a-3 can rotate to avoid applying downward friction to the drainage tube 11-1 during the cerebrospinal fluid expulsion process, thus avoiding significant downward pulling force on the drainage tube 11-1. The rotational speeds of the motor 9 and the drive disc 3a determine the movement speed of the clamping device 4a. Therefore, the controller 2 controls the rotational speed of the motor 9, which in turn controls the movement speed of the clamping device 4a and the drainage speed. During operation, at least one clamp 4a of the lumbar cistern drainage speed control device compresses the drainage tube 11-1. This is to prevent the drainage tube 11-1 from being uncompressed, thereby preventing the cerebrospinal fluid from flowing down without being squeezed out, which would lead to inaccurate drainage speed.

[0025] Preferably, the number of radial elongated holes 3a-1 and clamping devices 4a is four, and the guide groove 7-1 is rectangular in shape with rounded corners.

[0026] The purpose of the groove adjustment device 6 driving the drainage tube groove 5 to move left and right is to facilitate the insertion of the drainage tube 11-1 into the drainage tube groove 5. Specifically, by moving the drainage tube groove 5 away from the clamping device 4a, the drainage tube 11-1 can be inserted into the drainage tube groove 5; after insertion, the drainage tube groove 5 is moved closer to the clamping device 4a to reset it.

[0027] The preferred structure of the channel adjustment device 6 is as follows: The channel adjustment device 6 includes an adjustment device base 6-2, a connecting plate 6-3, a clamping knob 6-4, and two guide rods 6-1. The adjustment device base 6-2 is fixedly installed, and the two guide rods 6-1 are spaced apart vertically. The guide rods 6-1 pass through the adjustment device base 6-2, and their two ends are connected to the drainage tube channel 5 and the connecting plate 6-3, respectively. The clamping knob 6-4 passes through the connecting plate 6-3 and is threadedly connected to the adjustment device base 6-2, thus clamping the connecting plate 6-3. Loosening the clamping knob 6-4 moves the drainage tube channel 5 away from the clamping device 4a. After moving the drainage tube channel 5 back to its original position, tightening the clamping knob 6-4 prevents the drainage tube channel 5 from moving again.

[0028] To avoid excessive clamping force of the clamping roller 4a-3 on the drainage tube 11-1 due to potential manufacturing errors, which could affect the movement of the clamping roller 4a-3, it is preferable to provide a rubber pad 5-1 on the bottom of the drainage tube groove 5. The rubber pad 5-1 can be slightly compressed, thus avoiding the aforementioned situation.

[0029] Further preferred embodiments of the present invention are as follows: the lumbar sac drainage speed control device includes a device box 1, the device box 1 includes a box body 1-1 and a box cover 1-2 covering the front end of the box body 1-1; the guide plate 7, drive plate 3a, drive shaft 8, clamping device 4a, drainage pipe groove 5, groove adjustment device 6, motor 9 and controller 2 are all located inside the device box 1; the upper and lower ends of the box body 1-1 are provided with pipe passage grooves 1-1-1, and the positions of the pipe passage grooves 1-1-1 and the drainage pipe grooves 5 correspond to those of the drainage pipe grooves 5.

[0030] The mounting box 1 is used to prevent exposed components, and each fixed component can be connected to the box body 1-1. The tube through slot 1-1-1 is used to pass through the drainage tube 11-1, and the drainage tube 11-1 can be inserted and removed by opening the box cover 1-2.

[0031] As mentioned above, this invention can be used in conjunction with existing drainage devices for lumbar ventricle drainage. For better results, the drainage device 11 can also be modified as part of this invention. Specifically, as follows... Figure 10As shown: The lumbar sac drainage rate control device includes a drainage device 11, which includes a drainage tube 11-1, a puncture needle 11-4, a drainage bag 11-5, a positioning flange 11-2, and a measuring cylinder 11-3. The puncture needle 11-4 and the drainage bag 11-5 are respectively connected to the two ends of the drainage tube 11-1. The positioning flange 11-2 and the measuring cylinder 11-3 are set on the drainage tube 11-1. The positioning flange 11-2 is close to the puncture needle 11-4, and the measuring cylinder 11-3 is close to the drainage bag 11-5.

[0032] The clamping device 4a has a clamping wheel 4a-3, which, although it will not exert a large downward pull on the drainage tube 11-1, may still exert a small downward pull. For example... Figure 5 As shown, the positioning flange 11-2 can abut against the box 1-1 to prevent the drainage tube 11-1 from being pulled down and moving. The measuring cylinder 11-3 can visually measure the drainage volume, thus making the drainage speed more intuitive. The puncture needle 11-4 and drainage bag 11-5 are standard features, used to insert into the human body for drainage and to contain cerebrospinal fluid, respectively.

[0033] like Figures 6 to 8 As shown, the second type of lumbar sac drainage speed control device includes a drive disc 3b, a drive shaft 8, a drive shaft seat 10, a clamping device 4b, a drainage tube groove 5, a groove adjustment device 6, a motor 9, and a controller 2; The drive shaft seat 10 is fixedly set; the drive shaft 8 is horizontally set and installed on the drive shaft seat 10; the motor 9 is located behind the drive shaft 8 and connected to the drive shaft 8; the controller 2 can control the speed of the motor 9; the drive disk 3b is located in front of the drive shaft 8, the center of the drive disk 3b is connected to the drive shaft 8, and the drive disk 3b has at least three radial guide holes 3b-1, each radial guide hole 3b-1 is evenly distributed around the drive shaft 8 as the center. The clamping device 4b is configured to correspond one-to-one with the radial guide hole 3b-1. The clamping device 4b includes a clamping rod 4b-2, a clamping wheel 4b-3, and a spring 4b-1. The clamping rod 4b-2 is inserted into the radial guide hole 3b-1 and cooperates with the radial guide hole 3b-1. The drive disk 3b restricts the rotation of the clamping rod 4b-2 and restricts the clamping rod 4b-2 from exiting the radial guide hole 3b-1. The spring 4b-1 is located inside the radial guide hole 3b-1 and pushes the clamping rod 4b-2 outward. The clamping wheel 4b-3 is connected to the clamping rod 4b-2. The drainage tube groove 5 is set vertically and corresponds to the position of the drive disc 3b; the clamping wheel 4b-3 can enter the drainage tube groove 5 and clamp the drainage tube 11-1 placed in the drainage tube groove 5; during the operation of the waist pool drainage speed control device, at least one clamping device 4b clamps the drainage tube 11-1; the groove adjustment device 6 can drive the drainage tube groove 5 to move left and right.

[0034] like Figure 9As shown, the main working principle and effect of the lumbar cistern drainage rate control device in the second scheme are the same as those in the first scheme. It also has the beneficial effects of not requiring manual observation after the drainage rate is set, the drainage rate not changing, accurate drainage rate, and facilitating cerebrospinal fluid drainage. Only the specific structure is different.

[0035] The second type of lumbar sac drainage speed control device relies on the elastic force of spring 4b-1 to press the drainage tube 11-1. The elastic force of spring 4b-1 should be sufficient to press the drainage tube 11-1 tightly. During the rotation process after the clamping wheel 4b-3 presses the drainage tube 11-1 tightly, the reaction force of the drainage tube 11-1 on the clamping wheel 4b-3 causes the clamping rod 4b-2 to retract. Because the clamping rod 4b-2 needs to retract, the elastic force of spring 4b-1 cannot be too large to avoid making it difficult for the clamping rod 4b-2 to retract.

[0036] The radial guide holes 3b-1 and the clamping rod 4b are preferably six in number. The drive disc 3b should restrict the rotation of the clamping rod 4b-2 to prevent the clamping wheel 4b-3 from rotating around the axis of the radial guide hole 3b-1. Specifically, the cross-sectional shape of both the radial guide hole 3b-1 and the clamping rod 4b-2 can be a regular polygon, such as a square. The drive disc 3b restricts the clamping rod 4b-2 from exiting the radial guide hole 3b-1 to prevent the clamping rod 4b from moving out.
