An intracranial pressure sensor with a wire take-up structure

Abstract

This invention belongs to the field of sensors, and particularly relates to an intracranial pressure sensor with a cable retraction structure. Addressing the problem of loosening in existing sensors, the following solution is proposed: A display terminal is included, with a storage shell embedded in one side of its outer wall. The cable of this invention enters the storage shell through a through-hole and connects to the display terminal. A manually adjusted rotating block drives a threaded rod assembly to rotate under the support of a mounting frame, allowing corresponding clamping plates to slide relative to or opposite to each other along the mounting frame. A damping spring elastically pushes a receiving frame, causing a concave wheel and cam to slide against the cable, limiting and clamping the cable to prevent wobbling or displacement and maintain cable stability. When fixed clamping is required, the rotating block is adjusted to tighten the clamp, and the concave wheel and cam clamp the cable to prevent loosening. When cable retraction or extension is required, the rotating block is loosened to increase the space between the concave wheel and cam, thereby enabling retraction or extension.

Description

Technical Field

[0001] This invention relates to an intracranial pressure sensor, specifically an intracranial pressure sensor with a take-up structure, belonging to the field of sensor technology. Background Technology

[0002] In clinical practice, intracranial pressure monitors and matching intracranial pressure sensors are often used to accurately assess intracranial pressure caused by space-occupying lesions such as intracranial tumors, craniocerebral trauma, and cerebral hemorrhage, in order to meet the needs of diagnosis, treatment, and prognosis.

[0003] In existing technologies, such as the small-sized intracranial pressure sensor disclosed in CN220001752U, a bearing ring is used to support a fastening spring. The fastening spring is made of elastic material, which can deform when compressed and return to its original shape when the force is removed. It is used to clamp and fasten data cables or power cables. The inside of the fastening nut is arranged in a reverse funnel shape, which is larger at the bottom and smaller at the top. When the fastening nut is rotated and moved down, it can squeeze the fastening spring inward, thereby clamping and fastening the data cable or power cable. After storage, the data cable or power cable can be fixed and will not be pulled out by external force.

[0004] However, in implementing the relevant technology, the following problems were found in the design of the small-sized intracranial pressure sensor: In the existing technology, the cable is clamped and fixed by components such as fastening springs to prevent loosening. However, in actual use, the fastening springs have a certain fatigue value. This fastening method is prone to loosening over time. The fastening springs cannot fit perfectly with the fastening nuts, which makes the cable easy to loosen and affects the overall use of the device. In view of this, an intracranial pressure sensor with a cable take-up structure is provided to overcome the above defects. Summary of the Invention

[0005] To address the technical problem that the aforementioned fastening spring has a certain fatigue value, and that this fastening method is prone to loosening over time, and that the fastening spring cannot perfectly match the fastening nut, resulting in the cable easily loosening and affecting the overall use of the equipment, this invention provides an intracranial pressure sensor with a cable take-up structure.

[0006] The present invention achieves the above objectives through the following technical solution: an intracranial pressure sensor with a wire take-up structure, including a display terminal, a storage shell is embedded in one side of the outer wall of the display terminal, and a wire through hole is opened at the top of the storage shell, and an adjustment mechanism is provided inside the storage shell;

[0007] The adjustment mechanism includes a mounting frame, which is fixed inside the storage shell. A threaded rod assembly extends from the inside of the mounting frame. A rotating block is fixed to one end of the threaded rod assembly that extends out of the storage shell. A clamping plate is slidably connected to the outer wall of the end of the threaded rod assembly located inside the mounting frame. A guide groove is provided on the inner wall of the mounting frame corresponding to the position of the clamping plate. A damping spring is embedded in the outer wall of the clamping plate. A receiving frame is connected to the end of the damping spring away from the clamping plate. A concave wheel is rotatably connected inside the receiving frame. A cam is provided on one side of the concave wheel.

[0008] As a further embodiment of the present invention: the threaded rod assembly is threadedly connected to the clamping plate, and the clamping plate forms a sliding structure with the mounting bracket through the guide groove.

[0009] As a further embodiment of the present invention: the receiving frame forms an elastic structure with the clamping plate through a damping spring, and the receiving frame forms a rotating structure with the cam.

[0010] As a further embodiment of the present invention: a connecting plate is fixedly installed on one side of the outer wall of the receiving frame, and a slider is fixed on the outer wall of the connecting plate at the position corresponding to the guide groove.

[0011] As a further embodiment of the present invention: the front end of the storage shell is rotatably connected to an adjustment block, and a drive rod extends through the interior of the adjustment block. A limit plate is fixed to one end of the drive rod that is inserted into the outer wall of the storage shell.

[0012] As a further embodiment of the present invention: a pressing mechanism is provided above the connecting plate, the pressing mechanism includes a fixing block, the fixing block is fixedly installed on the top of the connecting plate, and a limiting groove is formed on the axial inner wall of the fixing block, a locking block is inserted into the inside of the limiting groove, and a sponge is embedded in the outer wall of the locking block.

[0013] As a further aspect of the present invention: the card block forms a sliding structure with the fixing block through the limiting groove, and the fixing block has an L-shaped structure.

[0014] As a further embodiment of the present invention: the mounting frame is provided with abutting mechanisms on both sides of the bottom end. The abutting mechanism includes a support rod, which is fixedly installed on one side of the bottom end of the mounting frame. A connecting rod is fixed to the outer wall of the axial end of the support rod. A telescopic spring is embedded inside the connecting rod, and a through rod protrudes from inside the connecting rod.

[0015] As a further embodiment of the present invention: the abutting mechanism further includes a fixing frame, which is fixed to the top of the protruding rod, and an abutting wheel is rotatably connected inside the fixing frame.

[0016] The beneficial effects of this invention are as follows: the cable enters the storage shell through the cable threading hole and connects to the display terminal. The manually adjusted rotating block drives the threaded rod assembly to rotate under the support of the mounting frame, and the corresponding clamping plates slide relative to or opposite to each other along the mounting frame. In conjunction with the damping spring, the receiving frame is pushed elastically, allowing the concave wheel and cam to slide against the cable and limit and clamp the cable, preventing shaking or deviation and maintaining cable stability. When fixed clamping is required, the rotating block is adjusted to tighten the cable, and the concave wheel and cam clamp the cable to prevent loosening. When the cable needs to be retracted or extended, the rotating block is loosened to increase the space between the concave wheel and cam, thereby enabling retraction and extension. The concave wheel and cam improve the smoothness of sliding, and the connecting plate and slider slide along the guide groove to improve the stability of the adjustment process.

[0017] The manual rotation of the adjusting block drives the drive rod to rotate, thereby winding the cable. Two limiting plates limit the winding cable, allowing the cable to overlap in a single layer and preventing tangling. The limiting groove of the fixing block engages with the locking block and is fixed with bolts. The connecting plate drives the fixing block. At the same time, the sponge is slightly larger than the concave wheel and cam, so that the sponge can compress the cable. When the cable is wound up and unwound, it can clean the outer wall of the cable. It also makes it convenient to replace and maintain the sponge after the locking block is disassembled and installed at regular intervals.

[0018] The axial end of the support rod is located between two limiting plates. The connecting rod, which is fixed by the support rod, is pushed by the telescopic spring to slide stably along the connecting rod. This allows the fixing frame to drive the two contact wheels to contact the wound cable. The elastic push of the telescopic spring allows the contact wheels to press firmly on the cable, so that the cable is compressed during winding and unwinding to prevent loosening. This would cause the cable to loosen inside the storage shell, resulting in shaking or even tangling. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1 to 6As shown, an intracranial pressure sensor with a wire-retracting structure includes a display terminal 1. A storage shell 2 is embedded in one side of the outer wall of the display terminal 1. A wire-passing hole 3 is opened at the top of the storage shell 2. An adjustment mechanism 4 is provided inside the storage shell 2. The adjustment mechanism 4 includes a mounting bracket 402, which is fixed inside the storage shell 2. A threaded rod assembly 403 extends out of the mounting bracket 402. A rotating block 401 is fixed to one end of the threaded rod assembly 403 that extends out of the storage shell 2. A clamping plate 40 is slidably connected to the outer wall of the end of the threaded rod assembly 403 located inside the mounting bracket 402. 4. A guide groove 405 is provided on the inner wall of the mounting bracket 402 corresponding to the position of the clamping plate 404. A damping spring 406 is embedded in the outer wall of the clamping plate 404. A receiving bracket 407 is connected to the end of the damping spring 406 away from the clamping plate 404. A concave wheel 408 is rotatably connected inside the receiving bracket 407. A cam 409 is provided on one side of the concave wheel 408. A threaded rod assembly 403 is threadedly connected to the clamping plate 404. The clamping plate 404 and the mounting bracket 402 form a sliding structure through the guide groove 405. The receiving bracket 407 and the clamping plate 404 are connected through the damping spring 406. The space between the support frame 407 and the cam 409 forms an elastic structure. A connecting plate 5 is fixedly installed on one side of the outer wall of the support frame 407, and a slider 6 is fixed on the outer wall of the connecting plate 5 at the position corresponding to the guide groove 405. The cable enters the storage shell 2 through the wire hole 3 and connects to the display terminal 1. The manually adjusted rotating block 401 drives the threaded rod assembly 403 to rotate under the support of the mounting frame 402, and allows the corresponding clamping plate 404 to slide relative to or away from the mounting frame 402. With the help of the damping spring 406, the support frame 407 is elastically pushed, causing the concave wheel 408 and the cam 409 to move. The sliding contact cable is used to limit and clamp it, preventing wobbling or deviation and maintaining cable stability. When fixed clamping is required, the rotating block 401 adjusts the clamping, and the concave wheel 408 and cam 409 clamp the cable to prevent loosening. When the cable needs to be retracted or extended, the rotating block 401 is loosened to increase the space between the concave wheel 408 and cam 409, thereby enabling retraction and extension. The concave wheel 408 and cam 409 improve the smoothness of sliding, and the connecting plate 5 and slider 6 slide along the guide groove 405 to improve the stability of the adjustment process.

[0030] Example 2

[0031] In addition to all the technical features in Embodiment 1, this embodiment also includes: an adjusting block 7 rotatably connected to the front end of the storage shell 2; a driving rod 8 protruding from the interior of the adjusting block 7; a limiting plate 9 fixed to one end of the driving rod 8 inserted into the outer wall of the storage shell 2; a pressing mechanism 10 provided above the connecting plate 5; the pressing mechanism 10 includes a fixing block 1001, which is fixedly installed on the top of the connecting plate 5; a limiting groove 1002 is formed on the axial inner wall of the fixing block 1001; a locking block 1003 is inserted into the limiting groove 1002; a sponge 1004 is embedded in the outer wall of the locking block 1003; and the locking block 1003 forms a sliding joint with the fixing block 1001 through the limiting groove 1002. The structure of the fixing block 1001 is L-shaped. The adjustment block 7 is manually rotated to drive the drive rod 8 to rotate and thus wind up the cable. The two limiting plates 9 limit the winding cable, allowing the cable to overlap in a single layer and stack to prevent tangling. The limiting groove 1002 of the fixing block 1001 engages with the locking block 1003 and is fixed with bolts. The connecting plate 5 drives the fixing block 1001. At the same time, the sponge 1004 is slightly larger than the concave wheel 408 and the cam 409, so that the sponge 1004 can press the cable tightly. When the cable is wound up and unwound, it can clean the outer wall of the cable. It also makes it convenient to replace and maintain the sponge 1004 after the locking block 1003 is disassembled and installed at regular intervals.

[0032] Example 3

[0033] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] The mounting bracket 402 has abutment mechanisms 11 on both sides of its bottom end. Each abutment mechanism 11 includes a support rod 1101, which is fixedly mounted on one side of the bottom end of the mounting bracket 402. A connecting rod 1102 is fixed to the outer wall of the axial end of the support rod 1101. A telescopic spring 1103 is embedded inside the connecting rod 1102, and a through rod 1104 extends through the connecting rod 1102. The abutment mechanism 11 also includes a fixing frame 1105, which is fixed to the top of the through rod 1104. An abutment wheel 1106 is rotatably connected inside the fixing frame 1105. The axial end of the support rod 1101 is located between the two limiting plates 9. The connecting rod 1102, which is fixed by the support rod 1101, is pushed by the telescopic spring 1103 to push the through rod 1104 to slide stably along the connecting rod 1102. This allows the fixing frame 1105 to drive the two abutting wheels 1106 to abut against the wound cable. The elastic push of the telescopic spring 1103 allows the abutting wheels 1106 to press firmly against the cable, so that the cable is compressed during winding and unwinding to prevent loosening. This would cause the cable to loosen inside the storage shell 2, resulting in shaking or even tangling.

[0035] Working Principle: The display terminal 1 uses a storage shell 2 on one side to store cables. A rotating adjustment block 7 drives a drive rod 8 to rotate, allowing the cables to be unloaded and retracted through the cable threading hole 3. Two limit plates 9 with enlarged inner diameters facilitate the folding and rotation of individual cables, preventing tangling. Manual adjustment of the rotating block 401 rotates the threaded rod assembly 403, which consists of two bidirectional threaded rods fixed together. This allows the corresponding clamping plates 404 to slide relative to or away from each other along the mounting frame 402 via sliding guide grooves 405. A damping spring 406 elastically pushes the receiving frame 407, causing the corresponding two receiving frames 407 to rotate. Connected concave wheels 408 and cams 409 limit and clamp the cables, preventing loosening. Alternatively, the rotating block 401 can be adjusted to create a gap between the concave wheels 408 and cams 409, facilitating cable pulling or winding. The receiving frame 407 slides stably along the guide groove 405 via the slider 6 on one side and the slider 6 on the other side of the fixed connecting plate 5, preventing excessive clamping that could cause the damping spring 406 to bend and affect the stability of the receiving frame 407. The fixing block 1001 at the top of the connecting plate 5 slides into and engages with the locking block 1003 through the limiting groove 1002, and is then fixed to the fixing block 1001 with bolts. The sponge 1004 adhered to the locking block 1003 can clamp the cable and clean the outer wall of the sliding cable, while also facilitating periodic replacement. Under the fixation of the mounting frame 402, the support rod 1101 is axially inserted between the two limiting plates 9. The telescopic spring 1103 embedded in the connecting rod 1102 elastically pushes the through rod 1104, causing the fixing frame 1105 to drive the two contact wheels 1106 to engage when the cable is wound up, preventing loosening, which could lead to detachment or even entanglement.
