Description

Technical Field

[0001] This utility model relates to the field of fixation devices, specifically an adjustable ventricular drainage suspension fixation device. Background Technology

[0002] External cerebrospinal fluid drainage refers to the continuous drainage of cerebrospinal fluid from the ventricles or lumbar cisterns into a closed external system. Its main purpose is to drain bloody or contaminated cerebrospinal fluid outside the cranium. It is also sometimes used to detect and control intracranial pressure and to inject drugs through the drainage tube.

[0003] During the drainage process, it is required to be fully enclosed and maintain a constant height to keep the entire drainage system sealed and prevent leakage; it is also necessary to fix it properly to ensure smooth drainage, even drainage speed, and prevent backflow. Therefore, it is necessary to select a suitable suspension and fixing device, such as an adjustable ventricular drainage suspension and fixing device with publication number CN211962687U, which uses a sliding I-shaped structure to drive the hook, thereby adjusting the height of the drainage drip. However, the adjustment process requires manual operation and the positioning accuracy is insufficient.

[0004] After cerebrospinal fluid external drainage, continuous drainage is required for several days. In order to meet the needs of patient care, the head of the bed needs to be raised or lowered frequently, which will cause changes in the position of the ventricular drainage device. If medical staff do not adjust the suspension height of the drainage device in time, it will lead to insufficient or excessive drainage, which may endanger the patient's life in severe cases. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable ventricular drainage suspension and fixation device. The contact position between the electrode pads and the resistance coil changes, thus reflecting the angle change of the head of the bed through resistance. Based on this, a controller adjusts the position of the height adjustment component and the height of the hook relative to the infrared measuring device. This prevents changes in the position of the head of the bed and the patient's head from affecting the ventricular drainage, thereby avoiding potential danger to the patient. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable ventricular drainage suspension and fixing device, including a support rod, a height adjustment component is provided on the front side of the support rod, and a scale is provided on the front side of the height adjustment component via a slide rail;

A movable block is provided on the top of the infrared measuring device. Two hooks are fixedly installed on the front side of the movable block. The movable block is located on the front side of the scale via a slide rail. The hooks are telescopic and can be adjusted in height according to the ventricle drainage device.

[0008] An electric push rod is provided on one side of the scale, and the two ends of the electric push rod are fixedly connected to the infrared measuring device and the moving block, respectively.

[0009] Furthermore, a vertical plate is fixedly provided at the top of the upright, and a winding wheel is provided on the rear side of the upright plate via a rotating shaft, with a tension rope wound around the outer end of the winding wheel;

[0012] A controller is fixedly installed on the rear side of the pole, the infrared measuring device is located at the input end of the controller, the electric push rod is located at the output end of the controller, and the motor is located at the output end of the controller.

[0013] Furthermore, an angle detection component is provided on the rear side of the clamping plate. The angle detection component includes a telescopic rod that is mounted on the rear side of the clamping plate via a pivot. A scale is fixedly provided at one end of the telescopic rod, and the scale has angle markings.

[0014] Furthermore, a pressure plate is provided on the front side of the dial, and a screw is provided on the pressure plate through the pressure plate;

[0015] The bottom end of the screw is fixedly connected to the telescopic rod. Two nuts are threaded on the screw, and the pressure plate is clamped between the two nuts. The position of the pressure plate on the screw can be adjusted by the nuts.

[0016] Furthermore, a central shaft is fixedly provided on the rear side of the dial, a sleeve is fitted on the outer end of the central shaft, a resistance ring is embedded in the outer end of the central shaft, and an electrode plate that contacts the outer end of the resistance ring is embedded on the inner wall of the sleeve.

[0017] The resistor coil and electrode plate are both located at the input end of the controller.

[0019] Compared with the prior art, this utility model provides an adjustable ventricular drainage suspension and fixation device, which has the following beneficial effects:

[0020] 1. The position of the patient's lateral ventricle plane is determined by an infrared measuring device, which is used to determine the baseline position during drainage, thus improving the accuracy of positioning. The controller can control the extension and retraction of the electric push rod, control the sliding of the moving block, and adjust the position of the hook so that the drainage device suspended on the hook is always 10-15cm above the lateral ventricle plane, to ensure that drainage can be carried out at a normal speed.

[0021] 2. The angle detection component is connected to the head of the bed by pressing a pad, so that the angle detection component can move synchronously with the position and angle of the head of the bed. During the movement of the angle detection component, the contact position between the electrode pad and the resistance coil will also change. This reflects the angle change of the head of the bed through resistance. Based on this, the controller controls the position of the height adjustment component and the height of the hook relative to the infrared measuring device, so as to avoid the changes in the position of the head of the bed and the patient's head from affecting the patient's brain drainage, thereby avoiding the danger to the patient.

[0030] To make the technical means, creative features, and achieved objectives and effects of this utility model readily understandable, the present utility model will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1-7 As shown, this utility model provides an adjustable ventricular drainage suspension and fixation device, including a pole 1, a height adjustment component 5 on the front side of the pole 1, and a scale 501 on the front side of the height adjustment component 5 via a slide rail;

[0032] An infrared measuring device 505 is fixedly provided on the front side of the scale 501. The position of the infrared measuring device 505 is aligned with the zero mark line of the scale 501. A moving block 502 is provided on the top of the infrared measuring device 505. Two hooks 504 are fixedly provided on the front side of the moving block 502. The moving block 502 is located on the front side of the scale 501 via a slide rail.

[0033] The infrared measuring device 505 is aligned with the zero mark of the scale 501. This position should be aligned with the inlet of various types of external ventricular drainage devices. Since the distance between different drainage bags or bottle hanging ears and the inlet is different, a retractable hook 504 needs to be designed to adjust the hanging position of various types of drainage devices, ensuring that the position of the drainage tube inlet is aligned with the zero mark. The zero point needs to be aligned with the plane of the patient's lateral ventricle.

[0034] An electric push rod 503 is provided on one side of the scale 501. The two ends of the electric push rod 503 are fixedly connected to the infrared measuring device 505 and the moving block 502, respectively. A controller 10 is fixedly provided on the rear side of the upright 1. The infrared measuring device 505 is located at the input end of the controller 10, and the electric push rod 503 is located at the output end of the controller 10.

[0035] The support rod 1 is fixed to the patient's bed. The height of the height adjustment component 5 on the support rod 1 is adjusted so that the infrared measuring device 505 is flush with the plane of the patient's lateral ventricle. The position of the patient's lateral ventricle plane is determined by the infrared measuring device 505. The infrared measuring device 505 can emit infrared rays. Part of the emitted infrared rays are absorbed, and the other part is reflected back and received by the infrared measuring device 505. The target object can be located by the received infrared signal, thereby determining the baseline position during drainage and improving the positioning accuracy. The controller 10 can control the extension and retraction of the electric push rod 503, control the sliding of the moving block 502, and adjust the position of the hook 504 so that the drainage device suspended on the hook 504 is always 10-15cm higher than the plane of the lateral ventricle to ensure that drainage can be carried out at a normal speed.

[0036] In order to flexibly adjust the height of the height adjustment component 5, such as Figure 1 , 2 As shown in Figure 7, a vertical plate 9 is fixedly provided at the top of the vertical pole 1, and a winding wheel 7 is provided on the rear side of the vertical plate 9 through a rotating shaft. A tension rope 8 is wound around the outer end of the winding wheel 7.

[0037] The scale 501 is provided with an extension frame 4 on the other side. One end of the extension frame 4 extends to the rear side of the upright 1 and is fixedly connected to the bottom end of the tension rope 8. The front side of the upright plate 9 is fixedly provided with a motor 6 for driving the winding wheel 7 to rotate. The motor 6 is located at the output end of the controller 10.

[0038] The bottom end of the upright 1 is fixed with a clamping plate 2, and the top end of the clamping plate 2 is provided with a fastening bolt through a thread. The clamping plate 2 is clamped on the edge of the bed, and the fixing device can be installed on the hospital bed after the fastening bolt is tightened.

[0039] When the patient's head position changes, the controller 10 controls the motor 6 to run. The motor 6 drives the winding wheel 7 to rotate and pulls the extension frame 4 through the tension rope 8. The extension frame 4 will drive the height adjustment component 5 to move upward. When the winding wheel 7 reverses, the tension rope 8 is released and the height adjustment component 5 moves downward under the action of gravity. By controlling the height adjustment component 5 to move up and down, the infrared measuring device 505 is aligned with the plane of the patient's lateral ventricle again.

[0040] In order to accurately sense the angle of the headboard, such as Figure 1 , 2 As shown in Figures 3 and 5, an angle detection component 3 is provided on the rear side of the clamping plate 2. The angle detection component 3 includes a telescopic rod 301 that is mounted on the rear side of the clamping plate 2 via a pivot. A scale 302 is fixedly provided on one end of the telescopic rod 301, and the scale 302 has an angle scale.

[0041] The dial 302 is provided with a pressure plate 303 on its front side, and the pressure plate 303 is provided with a screw 310 that passes through the pressure plate 303;

[0042] The bottom end of the screw 310 is fixedly connected to the telescopic rod 301. Two nuts are threaded on the screw 310, and the pressure plate 303 is clamped between the two nuts. The position of the pressure plate 303 on the screw 310 can be adjusted by the nuts.

[0043] Fix the upright 1 to the edge of the bed, and the clamp 2 is located at the pivot of the headboard. Then slide the pressure plate 303 on the screw 310 so that it rests on the headboard. Then tighten the two nuts to fix the position of the pressure plate 303. In this way, when the angle and position of the headboard change, the angle detection component 3 moves synchronously with the headboard through the pressure plate 303, and the telescopic rod 301 also rotates.

[0044] The rotation of angle detection component 3 reflects changes in the headboard angle, such as... Figure 2 , 3 As shown in Figures 6 and 7, a central shaft 307 is fixedly provided on the rear side of the dial 302. A sleeve 304 is sleeved on the outer end of the central shaft 307. A resistance coil 308 is embedded on the outer end of the central shaft 307. An electrode plate 309 that contacts the outer end of the resistance coil 308 is embedded on the inner wall of the sleeve 304.

[0045] The resistor coil 308 and electrode plate 309 are both located at the input end of the controller 10. The bottom end of the sleeve 304 is fixedly provided with a swing arm 305, and the bottom end of the swing arm 305 is fixedly provided with a weight 306. The weight of the weight 306 keeps the swing arm 305 in a vertical state.

[0046] The controller 10 is connected to the hospital's computer via a network module.

[0047] Changes in the angle and position of the headboard will cause the telescopic rod 301 to rotate, and the position of the dial 302 will change accordingly. However, regardless of its position change, the swing arm 305 remains perpendicular to the ground. Therefore, changes in the position of the dial 302 will cause the sleeve 304 to rotate relative to the central axis 307, and the contact position between the electrode 309 and the resistance coil 308 will also change. This allows the resistance to reflect changes in the headboard angle, and based on this, the controller 10 controls the position of the height adjustment component 5 and the height of the hook 504 relative to the infrared measuring device 505. This prevents changes in the headboard and patient's head position from affecting the patient's brain drainage, thus avoiding potential danger to the patient. Furthermore, when a change in the headboard position is detected, an alarm message can be sent to the hospital's computer via the network module, serving as a reminder.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
