Description

Technical Field

[0001] The present invention relates to the technical field of intracranial pressure detection devices, and specifically to a non-invasive intracranial pressure detection device based on dual sensors of pressure and displacement. Background Art

[0002] An intracranial pressure monitor refers to a dedicated medical device for measuring the intracranial pressure of the human body, applicable to the abnormal monitoring of intracranial pressure caused by craniocerebral injury, cerebral hypoxia, cerebrovascular diseases, intracranial inflammation, etc. It works in conjunction with a sensor. The existing intracranial pressure monitor, such as a medical brain intracranial pressure monitor disclosed in CN219422796U with the authorization announcement number, is provided with dust-proof nets at positions such as heat dissipation holes and heat dissipation grooves where dust is likely to enter, reducing the accumulation of dust directly at positions such as heat dissipation holes and heat dissipation grooves that are difficult to clean; the dust-proof nets are fixed by magic tapes and can be disassembled at any time during regular cleaning, and the installation and disassembly methods are convenient and fast.

[0003] Before the intracranial pressure monitor is used, zero adjustment work needs to be carried out. First, insert the probe wire into the intracranial pressure monitor, then connect the probe to the probe wire, turn on the intracranial pressure monitor, and then insert the probe into a bottle filled with physiological saline for zero adjustment. During the process of inserting the probe into the bottle and during the zero adjustment process after insertion, it should be noted that the probe cannot contact the bottle wall and cannot be inserted too deep, and it needs to be held by hand all the time. After the zero adjustment is completed, connect the probe to the skull drill fixing clip. During detection, the pressure sensor and the displacement sensor are used in combination (the pressure sensor and the displacement sensor are pre-placed in the skull), and the electronic sensor can produce zero drift affected by temperature, so multiple zero adjustments are required, and the current existing zero adjustment operation is relatively troublesome.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Please refer to Figures 1 - 10, A non-invasive intracranial pressure detection device based on dual sensors of pressure and displacement, comprising an intracranial pressure monitor main body 1 (the pressure sensor and displacement sensor are pre-placed intracranially), a detection line 9 and a probe 14. A rectangular frame 4 is fixedly installed on one side of the intracranial pressure monitor main body 1. A rectangular shell 2 is slidably arranged outside the rectangular frame 4. A rotating plate 3 is rotatably installed on one side of the rectangular shell 2. A connecting member for controlling the rotation of the rotating plate 3 is arranged between the rectangular frame 4 and the rectangular shell 2. The connecting member includes a serrated plate 17 fixedly installed on the lower wall of the rectangular frame 4. A groove 18 is formed on one side of the rectangular shell 2 where it is located on the side of the intracranial pressure monitor main body 1. A rotating rod 19 rotatably connected to the rectangular shell 2 is fixedly installed at the lower end of the rotating plate 3. A connecting gear 16 is fixedly connected to the lower end of the rotating rod 19 and is located in the groove 18. The connecting gear 16 meshes with the serrated plate 17. An installation member for fixing the probe 14 and a support member for zero adjustment are installed inside the rotating plate 3. The installation member includes a fixing block 20 fixedly installed inside the rotating plate 3. A plurality of elastic clips 23 for clamping the probe 14 are fixedly installed on the fixing block 20. The support member includes a fixing shell 13 fixedly installed inside the rotating plate 3. A plurality of spare bottles 21 are placed inside the fixing shell 13. The bottles 21 are filled with physiological saline (for single use, facilitating the replacement of clean physiological saline, without the need to temporarily pour physiological saline into a container every time for zero adjustment or subsequent cleaning work). The physiological saline is used for the zero adjustment work before the use of the intracranial pressure monitor main body 1 and the cleaning work after the internal pressure detection. When performing zero adjustment before use, only need to pull the rectangular shell 2 to move. Through the cooperation of the connecting gear 16 and the serrated plate 17, drive the rotating plate 3 to rotate, and turn out the probe 14 and the physiological saline. When performing zero adjustment, connect one end of the probe 14 to the detection line 9, then pull down one end of the probe 14 and insert its lower end into the bottle 21. Since the probe 14 is always clamped by the elastic clip 23 (the elastic clip 23 fixes the probe 14, facilitating the storage and carrying of the probe 14 without the need for additional packing and carrying), there is no need to always hold the probe 14. When the displacement sensor detects that zero adjustment is needed during the process, only need to pull the rectangular shell 2 and then perform the adjustment according to the above steps. Because the electronic sensor can produce zero drift affected by temperature and may need to perform zero adjustment too many times during the process, there is no need to carry various tools additionally at this time;

[0028] A moving component for storing the detection line 9 is arranged in the rectangular frame 4, and a rotating component for controlling the movement of the moving component is also arranged in the rectangular frame 4. Bayonet holes 7 are provided on both sides of the rectangular shell 2, and one end of the detection line 9 passes through one of the bayonet holes 7, and the other bayonet hole 7 is used to limit the rotating component. An installation cavity 24 is arranged in the rotating plate 3, and a reinforcement component is arranged in the installation cavity 24. The rotation of the rotating plate 3 is used to control the movement of the reinforcement component. The moving component includes two mounting plates 5 that are slidingly connected to the side walls of the intracranial pressure monitor body 1, a plurality of connecting plates 11 are fixedly installed on one side of the mounting plate 5, and a limiting roller 6 is rotatably installed on one side of the connecting plate 11. One end of the detection line 9 is plugged into the intracranial pressure monitor body 1, and the other end bypasses the plurality of limiting rollers 6 and passes through the rectangular frame 4 and one of the bayonet holes 7. The rotating component includes a rotating gear 12 that is rotatably connected to the inner wall of the rectangular frame 4, and two A sawtooth bar 8 meshing with the rotating gear 12 is fixedly installed on one side of the mounting plate 5, and a rectangular block 10 is fixedly installed on one end of the rotating shaft of the rotating gear 12. The rectangular block 10 is in sliding contact with one of the bayonet holes 7. For ease of use, a longer detection line 9 is generally provided. When in use, the intracranial pressure monitor body 1 is placed on one side of the bed. By winding the detection line 9 around a plurality of limiting rollers 6, it is convenient to store the detection line 9. Before use, the rectangular block 10 is limited by the bayonet hole 7 to prevent the rotating gear 12 from rotating and loosening the detection line 9. When the intracranial pressure monitor body 1 needs to be used, the rectangular shell 2 is pulled to disengage the rectangular block 10 from the bayonet hole 7. At this time, the detection line 9 can be pulled out to an appropriate length as required. After zeroing is completed, the rectangular shell 2 is pushed back so that the bayonet hole 7 limits the rectangular block 10 again.

[0029] As a further technical solution of the present invention, a retaining ring 15 is fixedly installed on the upper wall of the groove 18, a circular ring 28 is sleeved on the outer side of the rotating rod 19, and a plurality of limiting spring pieces 29 matching with the retaining ring 15 are fixedly installed on the outer side of the circular ring 28. After the rectangular shell 2 is pulled out and the rotating plate 3 is driven to rotate, the retaining ring 15 cooperates with the limiting spring pieces 29 to limit the rotating plate 3 in the absence of external force, thereby preventing it from rotating and affecting zero adjustment.

[0030] As a further technical solution of the present invention, the reinforcement component includes a connecting rod 22 rotatably connected to the installation cavity 24. The upper end of the connecting rod 22 is fixedly connected to the rectangular housing 2. Two special-shaped rings 25 are fixedly sleeved on the rotating plate 3. One side of the special-shaped ring 25 is in sliding contact with a push block 30 slidably connected to the rotating plate 3. A pressing plate 26 is slidably connected in the fixed housing 13. A connecting spring 27 is fixedly arranged between the pressing plate 26 and the fixed housing 13. A limiting plate 31 penetrating through the elastic clip 23 is slidably connected in the fixed block 20. A reset spring 32 is fixedly arranged between the limiting plate 31 and the fixed block 20. The two push blocks 30 are respectively fixedly connected to the limiting plate 31 and the pressing plate 26. When the rectangular housing 2 is pushed back, the bottle body 21 and the probe 14 are rotated into the rectangular housing 2. Through the cooperation of the special-shaped ring 25, the push block 30, the reset spring 32 and the connecting spring 27, the bottle body 21 and the probe 14 are squeezed and reinforced, which is convenient for the daily handling of the intracranial pressure monitor main body 1. When the rectangular housing 2 is pulled out, the rotating plate 3 rotates. Through the cooperation of the special-shaped ring 25, the push block 30, the reset spring 32 and the connecting spring 27, the reinforcement of the bottle body 21 and the probe 14 is released, which is convenient for the subsequent use of the bottle body 21 and the probe 14.

[0031] During use:

[0032] The pressure sensor and the displacement sensor are pre-placed in the skull. The intracranial pressure monitor main body 1 is carried to the front of the hospital bed and placed. Then, the rectangular housing 2 is pulled to move. During the initial pulling process, the serrated plate 17 drives the connecting gear 16 to rotate. The connecting gear 16 drives the rotating rod 19 to rotate. The rotating rod 19 drives the rotating plate 3 to rotate. The rotating plate 3 rotates the bottle body 21 and the probe 14 to the outside of the rectangular housing 2.

[0033] During the movement of the rectangular housing 2, the rectangular block 10 disengages from the bayonet 7. At this time, the limit on the rotating gear 12 is released. The detection line 9 is pulled out an appropriate length according to the needs, and then the zero adjustment work is carried out.

[0034] When the rotating plate 3 rotates, it drives the fixed block 20 and the fixed housing 13 to move. Through the cooperation of the special-shaped ring 25, the push block 30, the reset spring 32 and the connecting spring 27, the limiting plate 31 and the pressing plate 26 move, and the reinforcement of the bottle body 21 and the probe 14 is released.

[0035] After the rectangular housing 2 is pulled out and drives the rotating plate 3 to rotate, through the cooperation of the snap ring 15 and the limiting elastic piece 29 (when the rotating rod 19 rotates, the limiting elastic piece 29 is squeezed and deformed), the rotating plate 3 can be limited without external force to prevent it from rotating and affecting the zero adjustment.

[0036] When zeroing, remove one end of the probe 14 from the elastic clip 23 and connect it to the detection line 9. Open the lid of one of the bottle bodies 21, pull the other end of the probe 14 downward (this end of the probe 14 is still connected to the elastic clip 23), and insert its lower end into the bottle body 21 (note that the insertion should not be too deep and should not contact the inner wall of the bottle body 21). During zeroing, there is no need to manually hold it, and there will be no situation of hitting the wall due to jitter;

[0037] After zeroing, push the rectangular housing 2 back so that the bayonet 7 restricts the rectangular block 10 again. At this time, the detection line 9 of the rectangular housing 2 will not be pulled out. Then connect the probe 14 to the skull drill fixing clip. During detection, the pressure sensor and the displacement sensor are used in combination. Since the electronic sensor is affected by temperature and can produce zero drift, when the displacement sensor needs to be zeroed during detection, just follow the above steps;

[0038] When the rectangular housing 2 is pushed back, the serrated plate 17 drives the connecting gear 16 to rotate, the connecting gear 16 drives the rotating rod 19 to rotate, the rotating rod 19 drives the rotating plate 3 to rotate, and the rotating plate 3 turns the bottle body 21 and the probe 14 back to the inside of the rectangular housing 2;

[0039] When the rotating plate 3 rotates, it drives the fixed block 20 and the fixed housing 13 to move. Through the cooperation of the special-shaped ring 25, the push block 30, the return spring 32 and the connecting spring 27, the limiting plate 31 and the pressing plate 26 move to reinforce the bottle body 21 and the probe 14, which is convenient for daily handling of the intracranial pressure monitor main body 1;

[0040] After the detection is completed, when the detection line 9 needs to be retracted, just rotate the rectangular block 10.

[0041] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art may make equivalent replacements for its features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
