Description

Technical Field

[0001] This invention belongs to the field of cerebrospinal fluid drainage tube technology, specifically a cerebrospinal fluid drainage tube that can accurately measure pressure and intermittently control drainage. Background Technology

[0002] In neurosurgical clinics, cerebrospinal fluid drainage is a core treatment for diseases such as hydrocephalus, subarachnoid hemorrhage, and intracranial infection. The goal is to restore the dynamic balance between cerebrospinal fluid secretion and absorption, reduce intracranial pressure, and protect brain tissue function. Traditional drainage tubes have drawbacks such as inaccurate pressure measurement, limited drainage modes, and high risk of complications. However, cerebrospinal fluid drainage tubes that can accurately measure pressure and intermittently control drainage achieve synergistic optimization of pressure measurement and drainage through integrated design and intelligent control technology, providing a safer and more efficient treatment option for critically ill neurological patients.

[0003] Therefore, this patent proposes a cerebrospinal fluid drainage tube that can accurately measure pressure and intermittently control drainage. This device integrates a high-precision pressure monitoring system and introduces an intermittent drainage control mechanism. By using the main and auxiliary rolling shafts to lift the head or footboard, the patient's position can be adjusted. The change in position helps to balance intracranial pressure, reducing dependence on drainage equipment. The automatic adjustment function can reduce the frequency of moving the patient, avoid discomfort caused by changes in position, reduce the workload of medical staff, ensure effective drainage of cerebrospinal fluid, and prevent complications such as low intracranial pressure syndrome caused by excessive drainage. Summary of the Invention

[0004] The purpose of this invention is to provide a cerebrospinal fluid drainage tube that can accurately measure pressure and intermittently control drainage. It can automatically adjust the patient's head and feet height according to the pressure, give full play to the patient's own regulatory ability, assist in the use of drainage equipment, and reduce the patient's pain.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cerebrospinal fluid drainage tube capable of precise pressure measurement and intermittent controlled drainage is provided, comprising a nursing bed. A side panel is provided on the rear side of the nursing bed. A drainage bottle and a peristaltic pump are mounted on the surface of the side panel. A headboard and a footboard are movably connected to the middle of the nursing bed. A main push plate and a secondary push plate are respectively installed at the bottom of the headboard and the footboard. A drainage vertical tube is connected through the middle of the drainage bottle and the peristaltic pump. A main rolling shaft and a secondary rolling shaft are rotatably connected to the outer ends of the main push plate and the secondary push plate, respectively. The inner ends of the main push plate and the auxiliary push plate are respectively connected to the auxiliary support rod and the main support rod. The bottom surfaces of the main push plate and the auxiliary push plate are respectively fixedly connected to the main movable plate and the auxiliary movable plate. The middle of the headboard and the footboard are connected to the fixed shaft. The bottom surface of the nursing bed is fixedly connected to the analysis controller. The middle of the analysis controller is fixedly connected to the rotator. The bottom surface of the rotator is fixedly connected to the motor. The end of the motor is threaded with a rectangular threaded sleeve. The rotator is used to receive the direction signal from the analysis controller and control the horizontal rotation direction of the motor.

[0006] Optionally, a drainage horizontal tube and a pressure display are fixedly connected to the top of the drainage vertical tube, a sealing airbag is fixedly sleeved at the end of the drainage horizontal tube, an air guide tube is fixedly connected to the side wall of the drainage horizontal tube, a first one-way valve and an air pump are sequentially connected to the rear end of the air guide tube, and a second one-way valve and a pressure measuring tube are fixedly connected to the middle of the drainage horizontal tube.

[0007] Optionally, the analysis controller is electrically connected to a pressure display, which is used to analyze and display the intracranial pressure data detected in real time by the pressure measuring tube. The analysis controller is used to analyze the relationship between the intracranial pressure data on the pressure display and the normal intracranial pressure data and send a steering signal to the rotator. The second one-way valve and the pressure measuring tube are mounted on the fixing frame of the bed side plate.

[0008] Optionally, the ends of the main support rod and the auxiliary support rod are fixedly connected to a nursing bed, and the main support rod and the auxiliary support rod are located in the middle of the headboard and the footboard, respectively.

[0009] Optionally, the main push plate and the auxiliary push plate rotate around the auxiliary support rod and the main support rod, respectively, and the surfaces of the main rolling shaft and the auxiliary rolling shaft contact the headboard and the footboard.

[0010] Optionally, the main moving plate and the main pushing plate are vertically cross-connected, and the auxiliary pushing plate and the auxiliary moving plate are vertically cross-connected.

[0011] Optionally, the rectangular threaded sleeve contacts the sides of the main movable plate and the auxiliary movable plate, and the opening size of the main movable plate and the auxiliary movable plate is three times the diameter of the rectangular threaded sleeve.

[0012] Optionally, the rotation of the motor drives the rectangular threaded sleeve to move back and forth along the direction of the motor. The back and forth movement of the rectangular threaded sleeve drives the main movable plate and the auxiliary movable plate to rotate respectively. During the rotation of the motor, the rectangular threaded sleeve is in close contact with the main movable plate and the auxiliary movable plate and will not rotate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When intracranial pressure is high, this utility model can move a rectangular threaded sleeve driven by a motor, which in turn drives the main movable plate and the auxiliary movable plate to rotate. This, in turn, drives the main push plate to rotate around the auxiliary support rod and the auxiliary push plate to rotate around the main support rod. The main rolling shaft and the auxiliary rolling shaft lift the headboard or footboard to adjust the patient's position. This positional change helps to balance intracranial pressure, reducing reliance on drainage equipment. The automatic adjustment function can reduce the frequency of moving the patient, avoiding discomfort caused by positional changes. At the same time, it reduces the workload of medical staff, improves nursing efficiency, and the bed board adjustment is based on real-time pressure data, allowing for more precise adjustment and better adaptation to the individual needs of the patient.

[0014] 2. This utility model is fixed to the nursing bed by a main support rod and a secondary support rod, providing stable support for the movement of the headboard and footboard. The vertical cross connection between the main push plate and the main moving plate, and between the secondary push plate and the secondary moving plate, as well as the tight contact design between the rectangular threaded sleeve and the moving plate, ensure that there is no shaking or jamming during the adjustment of the bed board, thus ensuring the safety of the patient's position. Pressure measurement, drainage, and bed board adjustment are all automatically linked through the analysis controller. Medical staff only need to preset the pressure safety range, and the device can complete the subsequent operations autonomously without continuous manual monitoring. Attached Figure Description

[0022] Reference Figure 1-5The present invention describes a cerebrospinal fluid drainage tube with precise pressure measurement and intermittent controlled drainage, comprising a nursing bed 1, a side panel 2 at the rear of the nursing bed 1, a drainage bottle 3 and a peristaltic pump 4 mounted on the surface of the side panel 2, a headboard 5 and a footboard 6 movably connected to the middle of the nursing bed 1, a main push plate 8 and a secondary push plate 9 respectively mounted at the bottom of the headboard 5 and the footboard 6, a drainage vertical tube 7 penetratingly connected to the middle of the drainage bottle 3 and the peristaltic pump 4, and a main rolling shaft 10 and a secondary rolling shaft 11 rotatably connected to the outer ends of the main push plate 8 and the secondary push plate 9 respectively. The inner ends of the plate 9 are respectively connected to the auxiliary support rod 13 and the main support rod 12. The bottom surfaces of the main push plate 8 and the auxiliary push plate 9 are respectively fixedly connected to the main movable plate 17 and the auxiliary movable plate 27. The middle of the head bed plate 5 and the foot bed plate 6 are connected to the fixed shaft 16. The bottom surface of the nursing bed 1 is fixedly connected to the analysis controller 14. The middle of the analysis controller 14 is fixedly connected to the rotator 28. The bottom surface of the rotator 28 is fixedly connected to the motor 15. The end of the motor 15 is threadedly connected to the rectangular threaded sleeve 18. The rotator 28 is used to receive the turning signal of the analysis controller 14 and control the horizontal rotation direction of the motor 15.

[0023] Furthermore, a drainage horizontal tube 26 and a pressure display 19 are fixedly connected to the top of the drainage vertical tube 7, a sealing airbag 20 is fixedly sleeved at the end of the drainage horizontal tube 26, an air guide tube 21 is fixedly connected to the side wall of the drainage horizontal tube 26, a first one-way valve 22 and an air pump 23 are sequentially connected to the rear end of the air guide tube 21, and a second one-way valve 24 and a pressure measuring tube 25 are fixedly connected to the middle of the drainage horizontal tube 26.

[0024] Furthermore, the analysis controller 14 is electrically connected to a pressure display 19, which is used to analyze and display the intracranial pressure data detected in real time by the pressure measuring tube 25. The analysis controller 14 is used to analyze the relationship between the intracranial pressure data of the pressure display 19 and the normal intracranial pressure data and send a turning signal to the rotator 28. The second one-way valve 24 and the pressure measuring tube 25 are mounted on the fixed frame of the bed side plate 2.

[0025] Furthermore, the ends of the main support rod 12 and the auxiliary support rod 13 are fixedly connected to the nursing bed 1, and the main support rod 12 and the auxiliary support rod 13 are located in the middle of the headboard 5 and the footboard 6, respectively.

[0026] Furthermore, the main push plate 8 and the auxiliary push plate 9 rotate around the auxiliary support rod 13 and the main support rod 12 respectively, and the surfaces of the main rolling shaft 10 and the auxiliary rolling shaft 11 are in contact with the headboard 5 and the footboard 6.

[0027] Furthermore, the main moving plate 17 and the main pushing plate 8 are vertically cross-connected, and the auxiliary pushing plate 9 and the auxiliary moving plate 27 are vertically cross-connected.

[0028] Furthermore, the rectangular threaded sleeve 18 contacts the sides of the main movable plate 17 and the auxiliary movable plate 27, and the opening size of the main movable plate 17 and the auxiliary movable plate 27 is three times the diameter of the rectangular threaded sleeve 18.

[0029] Furthermore, the rotation of motor 15 drives rectangular threaded sleeve 18 to move back and forth along the direction of motor 15. The back and forth movement of rectangular threaded sleeve 18 drives main movable plate 17 and secondary movable plate 27 to rotate respectively. During the rotation of motor 15, rectangular threaded sleeve 18 is in close contact with main movable plate 17 and secondary movable plate 27 and will not rotate.

[0030] Working principle: The end of the drainage tube 26 is inserted into the patient's intracranial pre-set drainage site. The air pump 23 inflates the sealing balloon 20 through the air tube 21 until the balloon is tightly attached to the drainage site wall. The first one-way valve 22 is closed to prevent the balloon from leaking. Cerebrospinal fluid enters the drainage tube 26 under intracranial pressure. When it flows through the pressure measuring tube 25, the pressure measuring tube 25 processes the pressure signal and transmits the data to the pressure display 19. The pressure display 19 transmits the pressure data to the analysis controller 14. The analysis controller 14 processes the pressure data and compares the actual pressure value with the preset safety range to determine whether the drainage or bed board adjustment function needs to be activated. When the analysis controller 14 determines that the actual intracranial pressure is higher than the preset upper limit, it immediately sends a start signal to the peristaltic pump 4.

[0031] When the controller 14 determines that the intracranial pressure is abnormally high or low, and simple drainage cannot quickly balance the pressure, the rotor 28 operates, causing the rectangular threaded sleeve 18 at the end of the motor 15 to move towards the center of the main moving plate 17. Then, the motor 15 is started, and the rectangular threaded sleeve 18 at its end moves back and forth along the motor axis. When the rectangular threaded sleeve 18 moves forward, it pushes the main moving plate 17 to rotate around the contact point. The main moving plate 17 drives the main push plate 8 to rotate around the auxiliary support rod 13. The main rolling shaft 10 at the outer end of the main push plate 8 lifts the headrest board 5, raising the patient's head and using the weight The force promotes cerebrospinal fluid return and reduces intracranial pressure. When the pressure measuring tube 25 detects that the intracranial pressure has returned to a safe range, the analysis controller 14 controls the motor 15 to run in reverse, the rectangular threaded sleeve 18 resets, and the main moving plate 17, the auxiliary moving plate 27 and the bed board return to their initial positions, and the adjustment process automatically terminates. Conversely, the rotator 28 rotates the motor 15 180°, the rectangular threaded sleeve 18 enters the middle of the auxiliary moving plate 27, and then the motor 15 rotates, causing the rectangular threaded sleeve 18 to push the auxiliary push plate 9 and the foot bed board 6 to move, thereby raising the patient's feet and increasing intracranial pressure.

[0032] When the controller 14 detects that the pressure data continues to exceed the safe range, such as the intracranial pressure continuing to rise after drainage, the sudden drop in tubing pressure indicating leakage or blockage, or the failure of components such as the motor 15 or peristaltic pump 4, it will trigger an audible and visual warning signal to remind medical staff to intervene in time to investigate the problem. The device retains a manual operation interface.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
