Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a respiratory aid for medical imaging and radiological diagnosis. Background Technology

[0002] Medical imaging refers to the techniques and processes used to obtain images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or research. It includes two relatively independent research directions: medical imaging system and medical image processing. The former refers to the process of image formation, including research on imaging mechanisms, imaging equipment, and imaging system analysis; the latter refers to further processing of the acquired images, the purpose of which is either to restore the image that is not clear enough, to highlight certain feature information in the image, or to classify the image into patterns, etc. Some special patients need to use respiratory assist devices during radiological diagnosis. A respiratory assist device is a ventilator used to assist the patient in breathing.

[0003] Existing ventilators are equipped with casters at the bottom to facilitate movement. However, some ventilators cannot be adjusted in height, which is not convenient for patients lying on platforms at different heights. Furthermore, ventilators that cannot be adjusted in height may become unstable and tip over if moved too quickly in an emergency, potentially causing damage to the ventilator.

[0004] Therefore, in order to solve the above problems, the present invention proposes a respiratory assist device for medical imaging radiological diagnosis. Summary of the Invention

A transmission mechanism is provided at the middle position of the upper surface of the base. Symmetrically arranged triangular plates are fixedly connected to the bottom of the ventilator. Each triangular plate has a symmetrically arranged oblique groove. Symmetrically arranged wheel grooves are provided inside each triangular plate. A moving block is slidably connected inside each oblique groove. A rotating wheel is rotatably connected to each moving block at a position corresponding to the wheel groove. A disassembly mechanism is fixedly provided on each moving block. Symmetrically arranged support frames are fixedly connected to the upper surface of the base. Rotating rods are rotatably connected to each support frame. Symmetrically arranged support rods are fixedly connected to each rotating rod. Lifting grooves are provided on opposite sides of each support rod. Guide rods are fixedly connected inside each lifting groove. Lifting blocks are slidably connected inside each lifting groove. Connecting grooves are provided on opposite sides of each lifting block. A round rod is fixedly connected to each connecting groove.

[0007] Specifically, the clamping and fixing mechanism includes symmetrically arranged through slots and connecting rods, all of which are slidably connected to a fixing plate, and each connecting rod is fixedly connected to a fixing spring near its bottom end.

[0008] Specifically, the through slots in the clamping and fixing mechanism are symmetrically opened on the base, and the connecting rods in the clamping and fixing mechanism are provided in a total of four and symmetrically fixed to the bottom end of the base. The top ends of the fixing springs in the clamping and fixing mechanism are all fixed to the bottom end of the fixing plate, and the fixing plate in the clamping and fixing mechanism is concave at the position corresponding to each universal wheel.

[0009] Specifically, the transmission mechanism includes a lead screw, a lifting plate is threadedly connected to the lead screw near its top end, and a top rod is fixedly connected to the bottom end of the lifting plate at the corresponding through slot position in the clamping and fixing mechanism. Symmetrically arranged connecting frames are fixedly connected to the lifting plate, and a pulling plate is rotatably connected to each connecting frame.

[0010] Specifically, the lead screw in the transmission mechanism is rotatably connected to the middle position of the upper surface of the base, and the bottom end of the top rod in the transmission mechanism is slidably connected to the through groove in the clamping and fixing mechanism. There are two top rods in the transmission mechanism, and the pulling plate in the transmission mechanism is rotatably connected to the round rod on the lifting block.

[0011] Specifically, the disassembly mechanism includes a mounting plate with a sliding groove. Symmetrically arranged clamping plates are slidably connected inside the sliding groove. Clamping rods are fixedly connected to opposite sides of the clamping plates, and clamping springs are fixedly connected to opposite sides of the clamping plates. Pull rods are fixedly connected to the clamping plates at positions corresponding to the clamping springs.

[0012] Specifically, the mounting plate in the disassembly mechanism is fixedly connected to the moving block, the clamping spring in the disassembly mechanism is located inside the slide groove, the clamping spring in the disassembly mechanism is fixedly connected to the inner side wall of the slide groove, the pull rod in the disassembly mechanism is slidably connected to the mounting plate, and the pull rod in the disassembly mechanism is located in the hollow part of the clamping spring.

[0013] Specifically, the rotary groove and the inclined groove are in communication, the rotary wheel is slidably connected inside the rotary groove, the guide rod is slidably connected to the lifting block, and the top of the support rod is rotatably connected to the clamping rod in the disassembly mechanism.

The height-adjustable ventilator is easy to match with platforms of different heights. When the height of the ventilator is lowered, the stability will increase, which will reduce the chance of the ventilator tipping over when moving the ventilator, thus enhancing its practicality. The detachable ventilator is also convenient for staff to clean or repair.

[0016] (2) The present invention is equipped with a fixed spring, a fixed plate, a top rod, a lifting plate, a connecting rod, etc. When the lead screw drives the lifting plate to increase the height of the ventilator, the lifting plate will also drive the top rod to descend. The descending top rod will push the fixed plate, so that the fixed plate clamps and fixes the bottom universal wheel, preventing the ventilator after the height is adjusted from moving unexpectedly due to the universal wheel, and enhancing the stability of the ventilator in use.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-7 As shown, the present invention discloses a respiratory assist device for medical imaging radiological diagnosis, comprising a ventilator 1 and a base 2. The base 2 has symmetrically arranged casters 3 fixedly mounted at its bottom end, a clamping and fixing mechanism 4 at its bottom end, and a transmission mechanism 5 at the middle position of the upper surface of the base 2. The ventilator 1 has symmetrically arranged triangular plates 6 fixedly connected to its bottom end. Each triangular plate 6 has symmetrically arranged oblique grooves 7, and each triangular plate 6 has symmetrically arranged rotating wheel grooves 8 inside. A movable block 9 is slidably connected inside each oblique groove 7, and the movable block 9 rotates at positions corresponding to the rotating wheel grooves 8. The base 2 is connected to a rotating wheel 10. Each of the moving blocks 9 is fixedly equipped with a disassembly mechanism 11. The upper surface of the base 2 is fixedly connected to a symmetrically arranged support frame 12. Each of the support frames 12 is rotatably connected to a rotating rod 13. Each of the rotating rods 13 is fixedly connected to a symmetrically arranged support rod 14. Each of the support rods 14 has a lifting groove 15 on its opposite side. Each of the lifting grooves 15 has a guide rod 16 fixedly connected inside. Each of the lifting grooves 15 has a lifting block 17 slidably connected inside. Each of the lifting blocks 17 has a connecting groove 18 on its opposite side. Each of the connecting grooves 18 has a round rod 19 fixedly connected to it.

[0028] Specifically, the clamping and fixing mechanism 4 includes symmetrically arranged through slots 41 and connecting rods 42. Each connecting rod 42 is slidably connected to a fixing plate 43, and each connecting rod 42 is fixedly connected to a fixing spring 44 near its bottom end.

[0029] Specifically, the through slots 41 in the clamping and fixing mechanism 4 are symmetrically opened on the base 2. The connecting rods 42 in the clamping and fixing mechanism 4 are provided in a total of four and are symmetrically fixedly connected to the bottom end of the base 2. The top ends of the fixing springs 44 in the clamping and fixing mechanism 4 are all fixedly connected to the bottom end of the fixing plate 43. The fixing plate 43 in the clamping and fixing mechanism 4 is concave at the position corresponding to each universal wheel 3, so that the fixing springs 44 can be squeezed and contracted when the fixing plate 43 slides down.

[0030] Specifically, the transmission mechanism 5 includes a lead screw 51, a lifting plate 52 is threadedly connected to the lead screw 51 near the top end, and a top rod 53 is fixedly connected to the bottom end of the lifting plate 52 at the position corresponding to the through groove 41 in the clamping and fixing mechanism 4. A symmetrically arranged connecting frame 54 is fixedly connected to the lifting plate 52, and a pulling plate 55 is rotatably connected to each connecting frame 54.

[0031] Specifically, the lead screw 51 in the transmission mechanism 5 is rotatably connected to the middle position of the upper surface of the base 2, and the bottom end of the top rod 53 in the transmission mechanism 5 is slidably connected to the inside of the through groove 41 in the clamping and fixing mechanism 4. There are two top rods 53 in the transmission mechanism 5. The pulling plate 55 in the transmission mechanism 5 is rotatably connected to the round rod 19 on the lifting block 17. When the top rod 53 slides down, it can easily pass through the through groove 41 to drive the fixing plate 43 to move down. The pulling plate 55 can easily pull the lifting block 17 through the round rod 19.

[0032] Specifically, the disassembly mechanism 11 includes a mounting plate 111, on which a sliding groove 112 is provided. A symmetrically arranged clamping plate 113 is slidably connected inside the sliding groove 112. A clamping rod 114 is fixedly connected to the opposite side of the clamping plate 113, and a clamping spring 115 is fixedly connected to the far side of the clamping plate 113. A pull rod 116 is fixedly connected to the clamping plate 113 at the position corresponding to the clamping spring 115.

[0033] Specifically, the mounting plate 111 in the disassembly mechanism 11 is fixedly connected to the moving block 9. The clamping spring 115 in the disassembly mechanism 11 is located inside the slide groove 112. The clamping spring 115 in the disassembly mechanism 11 is fixedly connected to the inner side wall of the slide groove 112. The pull rod 116 in the disassembly mechanism 11 is slidably connected to the mounting plate 111. The pull rod 116 in the disassembly mechanism 11 is located in the hollow part of the clamping spring 115. The slidable connection between the pull rod 116 and the mounting plate 111 facilitates the lateral movement of the clamping plate 113.

[0034] Specifically, the rotary groove 8 and the inclined groove 7 are in a connected state, the rotary wheel 10 is slidably connected inside the rotary groove 8, the guide rod 16 is slidably connected to the lifting block 17, and the top end of the support rod 14 is rotatably connected to the clamping rod 114 in the disassembly mechanism 11. The support rod 14 facilitates the movement of the moving block 9 through the clamping rod 114.

[0035] When using the ventilator 1, to move it, simply lower it to its lowest possible height for stable movement. To adjust the height of the ventilator 1 or to fix the casters 3, first grasp the top of the lead screw 51 and rotate it. The rotation of the lead screw 51 causes the lifting plate 52 to slide downwards. As the lifting plate 52 moves downwards, it causes the top rod 53 and the connecting frame 54 to move downwards. The downward movement of the connecting frame 54 causes the pulling plate 55 to move along with it. The pulling plate 55 first rotates around the connecting frame 54 as its center, and then moves downwards. The pulling plate 55, through its rotational connection with the round rod 19, pulls the lifting block 17 downward. The lifting block 17 is guided by the guide rod 16, which restricts its movement trajectory within the lifting groove 15. As the lifting plate 52, the pulling plate 55, and the lifting block 17 move downward, they force each support rod 14 to rotate towards the center position on the base 2. The rotation of the support rods 14 towards the center position causes the mounting plate 111 to slide downward at an angle via the clamping rod 114. The downward sliding of the mounting plate 111 causes the moving block 9 to move downward within the angled groove 7. As the moving block 9 slides downwards, it drives the rotating wheel 10 to move. The rotating wheel 10 moves and rubs against the rotating wheel groove 8, thus passively rotating and making the movement of the moving block 9 smoother. When all the moving blocks 9 slide downwards at the same time, due to the inclined setting of the inclined groove 7, the triangular plate 6 will move the ventilator 1 upwards. The downward moving lifting plate 52 will drive the top rod 53 to pass through the through groove 41 and push to the top of the fixed plate 43. The downward movement of the fixed plate 43 will compress and contract the fixed spring 44. At this time, the top rod 53 continues to drive the fixed plate 43 to move downwards. Move the fixed plate 43 so that the recessed part on the side of the fixed plate 43 locks the caster 3. At this time, the height of the ventilator 1 and the caster 3 are all adjusted. When it is necessary to disassemble the ventilator 1, simply pull the pull rod 116 to the side. The pull rod 116 will drive the clamping plate 113 to move. The movement of the clamping plate 113 will squeeze and contract the clamping spring 115. At the same time, the movement of the clamping plate 113 will drive the clamping rod 114 to move. The movement of the clamping rod 114 will disengage from the top of the support rod 14. At this time, the support rod 14 and the clamping rod 114 are no longer connected, and the ventilator 1 can be completely removed.
