Description

Technical Field

[0001] This invention belongs to the field of thrombosis detection technology, and particularly relates to a device for detecting cerebral vascular thrombosis. Background Technology

[0002] Cerebral thrombosis, also known as cerebral thrombosis, is the most common type of cerebral infarction. It is a brain disease caused by lesions in the walls of cerebral arteries, narrowing or occlusion of the arterial lumen. Cerebral thrombosis is related to age; its incidence gradually increases with age. The main cause of cerebral thrombosis is lesions in the walls of cerebral arteries leading to atherosclerosis, plaque detachment, or narrowing and occlusion of the lumen, resulting in clinical manifestations. Risk factors for cerebral thrombosis include hypertension, hyperglycemia, hyperlipidemia, abnormal blood flow velocity, abnormal levels of coagulation factors and fibrinogen in the blood, advanced age, and unhealthy lifestyle habits.

[0003] A search revealed that application number CN202110011695.3 discloses a cerebral vascular thrombosis detection device, belonging to the field of cerebral vascular medical devices. This device includes an upper support plate, a base, a lifting mechanism, a removal mechanism, a moving mechanism, a detector, a slider, and a clamping mechanism. The lifting and removal mechanisms, installed between the upper support plate and the base, better connect with an emergency bed, improving the ease of patient movement. The moving mechanism on the upper support plate allows the patient's brain to be inserted into the detector. Two third and two fourth sliding grooves are provided at the upper end of the upper support plate, with sliders installed in each groove. A clamping mechanism on the upper support plate secures the patient's knees, shoulders, and neck, preventing movement during testing and affecting results. A bracket and hook on the upper surface of the upper support plate secure the infusion bottle, further enhancing the device's convenience.

Each primary mounting base 107 has a traveling gear 102 fixedly fitted at the same end. Each traveling gear 102 is connected to a toothed plate 7 below it through a meshing mechanism. The toothed plate 7 is fixedly connected to both sides of the upper surface of the ring-shaped support 1. The auxiliary lifting component 18 includes a limiting plate 801. The limiting plate 801 is fixedly connected to the inner surface of the two side plates 17. The middle of the two limiting plates 801 is provided with a first slide groove 802. A first slider 806 is installed in the first slide groove 802. An extension rod 805 is rotatably installed at one end of the first slider 806 on both sides. The form conversion component 15 includes a second slide rail 603. The second slide rail 603 is provided on both sides of the upper surface and the lower surface of the loading plate 606. The two ends of the upper second slide rail 603 are movably installed with sliding bases 617. The lower second slide rail 603 is installed with mounting bases 610. The middle of the loading plate 606 is provided with a second slide groove 609.

[0029] A first slide rail 11 is fixedly connected to the inner surface of the ring bracket 1. A fixed bracket 9 is installed inside the first slide rail 11. A mounting rod 22 is fixedly connected to the inner surface of the fixed bracket 9. A back plate 10 is rotatably mounted on the mounting rod 22. A connecting sheet metal 23 is installed at the lower end of the back plate 10. A support plate 12 is installed at the other end of the connecting sheet metal 23. A leg rest 13 is installed at the other end of the support plate 12. A shape conversion component 15 is installed on the lower surface of the back plate 10 and the support plate 12. The shape conversion component 15 is mounted on an L-shaped slide rail 14. The L-shaped slide rail 14 is fixedly connected to... On both sides of the lower surface of the ring support 1, a cerebral thrombosis detection device 20 is installed at one end of the ring support 1. A control panel 21 is installed on one side of the cerebral thrombosis detection device 20. An inclined support plate 16 is installed below the shape conversion component 15.

The telescopic rod 4 is installed in the fixed rod 5. The lower end of the fixed rod 5 is fixedly connected to... A base plate 6 is attached, and an inclined support plate 16 is fixedly connected to the upper surface of the base plate 6. The inclined support plate 16 is located below the form conversion component 15. Side plates 17 are fixedly connected to both sides of one end of the upper surface of the base plate 6. An auxiliary lifting component 18 is installed inside the side plates 17, and a lifting platform 19 is installed on the auxiliary lifting component 18. For elderly people who need to use wheelchairs due to declining mobility and are more prone to cerebral thrombosis, regular brain scans are necessary. First, place the wheelchair with its back facing the device. Placed on the lifting platform 19, the auxiliary lifting component 18 can be activated to raise and lower the wheelchair and the elderly person to a certain height. Then, with the help of staff, the elderly patient can be easily moved onto the support plate 12 and the backrest 10. The form conversion component 15 can then drive the backrest 10 and the support plate 12, together with the leg rest 13, to adjust the elderly patient into a lying position. After the test is completed, the rollers 616 and the inclined support plate 16 below can adjust the support height of the backrest 10 and the support plate 12, which also facilitates the elderly patient to finish the test.

[0030] An electric push rod 803 is fixedly connected to one side of the mounting bracket 804. The electric push rod 803 is installed on the inner surface of the side plate 17.

A slider 806 is set on one side of the upper extension rod 805. A lifting platform 19 is rotatably installed on the upper end of the two extension rods 805. The electric push rod 803 drives the mounting bracket 804 to move horizontally. The extension rod 805 is rotatably installed on the upper inner side of the mounting bracket 804. The outer surface of the upper extension rod 805 is installed in the first slide groove 802 through the slider 806. This allows the extension rod 805 to move around the upper end of the mounting bracket 804 as the center, so that the upper part of the lifting platform 19 moves to the upper part of the side plate 17 or to the lower part of the side plate 17. This can help elderly patients in wheelchairs to move to a certain height, which is convenient for elderly patients to undergo thrombosis detection.

[0031] Each rotating rod 101 has a sprocket 103 fixedly fitted at the same end, and a transmission chain 104 installed on each sprocket 103. The other end of each rotating rod 101 is fixedly fitted with a worm gear 105. A worm 106 is threadedly connected above each worm gear 105. One end of the worm 106 is fixedly connected to the output shaft of the first motor 108. The first motor 108 is fixedly connected to the lower surface of the fixed bracket 9. Since the fixed bracket 9 is installed in the annular bracket 1 through the first slide rail 11, starting the first motor 108 drives the worm 106 to rotate. The worm 106 drives the rotating rod 101 to rotate through the worm gear 105. When the rotating rod 101 rotates, it can drive the traveling gear 102 to engage with the toothed plate 7, causing the fixed bracket 9 to move back and forth along the toothed plate 7.

[0032] A second slider 608 is installed inside the second slide groove 609. The second slider 608 is installed inside the L-shaped slide rail 14. The sliding base 617 and the mounting base 610 are each connected to a lead screw 602 by threaded engagement. Each lead screw 602 is rotatably mounted on a second mounting base 604. Each second mounting base 604 is fixedly connected to the upper and lower surfaces of the loading plate 606. The upper and lower lead screws 602 are connected together by a first chain 605. One end of the upper lead screw 602 is fixedly connected to a second motor 601. The lead screws 602 on the upper and lower sides extend to the rear end of the loading plate 606, and the extensions of the lead screws 602 are connected together via a second chain 607. A roller 616 is rotatably mounted on the lower end of the mounting base 610 below, and the roller 616 contacts the upper surface of the inclined support plate 16. A first support rod 612 and a second support rod 615 are rotatably mounted on two sliding bases 617 inside the second slide rail 603 above. A mounting groove 613 is provided in the middle of the first support rod 612, and the second support rod 615 passes through the mounting groove 613. Support rod 13 and support rod 612 are arranged crosswise. Support rod 612 and support rod 615 are rotatably mounted together at their intersection via connecting rod 614. Both support rods 612 and 615 have a fixed base 611 rotatably mounted on their upper ends. The two fixed bases 611 are respectively fixedly connected to the rear surface of back plate 10 and the lower surface of support plate 12. Support rod 612 is longer at the upper end than support rod 615. Motor 601 drives lead screw 602 to rotate, and lead screw 602 drives a sliding base on one side. When seat 617 moves inward, the distance between the two sliding bases 617 is shortened, thereby causing the first support rod 612 and the second support rod 615 to rotate around the connecting rod 614, which supports the back plate 10 and the support plate 12. This allows the back plate 10 and the support plate 12 to be adjusted to a lying position for the elderly patient. After the test is completed, the height of the back plate 10 and the support plate 12 can be adjusted by the rollers 616 and the inclined support plate 16 below, which also makes it easier for the elderly patient to finish the test.

[0033] Working principle of the invention:

[0034] When using this device, for elderly people who need to use wheelchairs to get around due to declining mobility and who are more prone to cerebral thrombosis, regular brain scans are necessary. First, place the wheelchair with the back facing the device on the lifting platform 19. Activate the auxiliary lifting component 18 to raise and lower the wheelchair and the elderly person to a certain height. Then, with the help of staff, the elderly patient can be easily moved to the support plate 12 and backrest 10. The form conversion component 15 can then adjust the backrest 10 and support plate 12, along with the leg rest 13, to a lying position. After the scan, the rollers 616 and the inclined support plate 16 below can adjust the height of the backrest 10 and support plate 12, making it easier for the elderly patient to finish the scan.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
