[0002] An intracranial pressure monitor refers to a special medical device used to measure human intracranial pressure. It is suitable for monitoring abnormal intracranial pressure caused by craniocerebral injury, cerebral hypoxia, cerebrovascular disease and intracranial inflammation. It works with a sensor. Existing intracranial pressure monitors, such as a medical brain intracranial pressure monitor disclosed in authorization announcement No. CN219422796U, have dustproof nets set in heat dissipation holes, heat dissipation slots and other locations where dust can easily enter, to reduce the accumulation of dust directly in difficult-to-clean locations such as heat dissipation holes and heat dissipation slots; the dustproof net is fixed with Velcro and can be removed at any time for regular cleaning, and the assembly and disassembly method is convenient and quick.

[0003] Before using the intracranial pressure monitor, it is necessary to perform zero adjustment. First, plug the probe line into the intracranial pressure monitor, then connect the probe to the probe line, turn on the intracranial pressure monitor, and then insert the probe into a bottle filled with saline to perform zero adjustment. During the process of inserting the probe into the bottle and the zeroing process after insertion, be careful that the probe cannot contact the bottle wall and cannot be inserted too deep. It needs to be held by hand all the time. After zeroing, connect the probe to the skull drill clamp. During detection, it is used in conjunction with a pressure sensor and a displacement sensor (the pressure sensor and the displacement sensor are pre-placed in the skull), and the electronic sensor can produce zero drift due to temperature, so multiple zeroing is required.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

The lower end of the rotating rod 19 is located in the groove 18 and is fixedly connected to a connecting gear 16. The connecting gear 16 is meshed with the sawtooth plate 17. A mounting member for fixing the probe 14 and a support member for zeroing are installed on the inner side of the rotating plate 3. The mounting member includes a fixed block 20 fixedly installed on the inner side of the rotating plate 3, and a plurality of elastic clips 23 for clamping the probe 14 are fixedly installed on the fixed block 20. The support member includes a fixed shell 13 fixedly installed on the inner side of the rotating plate 3, and a A plurality of spare bottles 21 are provided, wherein the bottles 21 are filled with saline solution (for single use, so that clean saline solution can be easily replaced, and there is no need to temporarily pour saline solution into the container each time for zeroing or subsequent cleaning). The saline solution is used for zeroing before use of the intracranial pressure monitor body 1 and for cleaning after internal pressure detection. When zeroing before use, it is only necessary to pull the rectangular housing 2 to move, and the rotating plate 3 is driven to rotate by the cooperation of the connecting gear 16 and the sawtooth plate 17, so that the probe 14 and the saline solution are rotated out. When zeroing, one end of the probe 14 is connected to the detection line 9. Then, pull one end of the probe 14 downward and insert its lower end into the bottle body 21. Since the probe 14 is always clamped by the elastic clip 23 (the elastic clip 23 fixes the probe 14, making it easy to store and carry the probe 14 without having to pack it separately), there is no need to hold the probe 14 all the time. When the displacement sensor needs to be zeroed during the process, it is only necessary to pull the rectangular housing 2 and then adjust it according to the above steps. Because the electronic sensor may have zero drift due to the influence of temperature, it may be necessary to adjust zero too many times during the process. At this time, there is no need to carry various tools extra. 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.

[0018] 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.

[0019] 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 shell 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, an extrusion plate 26 is slidably connected in the fixed shell 13, a connecting spring 27 is fixedly arranged between the extrusion plate 26 and the fixed shell 13, a limiting plate 31 that penetrates 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, and the two push blocks 30 are fixedly connected to the limit plate 31 and the extrusion plate 26 respectively. When the rectangular shell 2 is pushed back, the bottle body 21 and the probe 14 are rotated into the rectangular shell 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 daily carrying of the intracranial pressure monitor main body 1. When the rectangular shell 2 is pulled out, the turning plate 3 rotates, and 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.

[0020] When using: The pressure sensor and the displacement sensor are placed in the skull in advance. The main body 1 of the intracranial pressure monitor is carried to the front of the bed and placed. Then the rectangular housing 2 is pulled to move. In the initial pulling process, the sawtooth 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 rotates the bottle body 21 and the probe 14 to the outside of the rectangular housing 2; When the rectangular housing 2 is moving, the rectangular block 10 is separated from the bayonet 7, and the limit on the rotating gear 12 is released. The detection line 9 is pulled out to a proper length according to the requirements, and then the zeroing work is performed; When the rotating plate 3 rotates, the fixed block 20 and the fixed housing 13 are driven 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 limit plate 31 and the extrusion plate 26 are moved to release the reinforcement of the bottle body 21 and the probe 14. After the rectangular housing 2 is pulled out and the rotating plate 3 is driven to rotate, the rotating plate 3 can be limited in position without external force by the cooperation between the clamping ring 15 and the limiting spring piece 29 (when the rotating rod 19 rotates, the limiting spring piece 29 is squeezed and deformed), so as to prevent the rotating plate 3 from rotating and affecting the zero adjustment. When adjusting the zero, remove one end of the probe 14 from the elastic clip 23 and connect it to the detection line 9, open the cover 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). There is no need to hold it manually when adjusting the zero, and there will be no collision with the wall due to shaking; After zeroing is completed, the rectangular housing 2 is pushed back so that the bayonet 7 limits the rectangular block 10 again. At this time, the detection line 9 of the rectangular housing 2 will not be pulled out, and then the probe 14 is connected to the skull drill fixing clamp. During detection, the pressure sensor and the displacement sensor are used in combination. Since the electronic sensor may produce zero drift due to the influence of temperature, when the displacement sensor detection needs to be zeroed, it can be carried out according to the above steps; 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 rotates the bottle body 21 and the probe 14 back to the inside of the rectangular housing 2; When the rotating plate 3 rotates, the fixed block 20 and the fixed housing 13 are driven 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 limit plate 31 and the extrusion plate 26 are moved to reinforce the bottle body 21 and the probe 14, so as to facilitate the daily transportation of the intracranial pressure monitor body 1; After the detection is completed, when the detection line 9 needs to be retracted, the rectangular block 10 can be rotated.

Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art that the features thereof are equivalently replaced.
