DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] like Figure 1 - Fig.10 As shown, the present invention provides a cardiopulmonary resuscitation device for cardiology, comprising: a base 1, a plurality of sliding rods 11 are fixedly connected inside the base 1, a clamping plate 12 is slidably installed on the plurality of sliding rods 11, a screw 13 is fixed to the bottom of the clamping plate 12, one end of the screw 13 extends out of the bottom of the base 1 and is slidably connected to the base 1, one end of the screw 13 extending out of the bottom of the base 1 is threadedly connected to a hexagonal nut 14, an adjusting mechanism 2 is rotatably connected to the top of the base 1, and a resuscitation unit 3 is connected to the adjusting mechanism 2.

[0034] Among them, the adjusting mechanism 2 includes a sleeve 21 rotatably connected to the top of the base 1 through a bearing. A first servo motor 22 is fixedly connected to the side wall of the sleeve 21. The output end of the first servo motor 22 is fixedly connected to a gear column 23. One side of the top of the base 1 away from the sleeve 21 is fixedly connected with an arc-shaped rack 24, and the arc-shaped rack 24 meshes with the gear column 23.

[0035] Among them, a pair of stoppers 25 are arranged on the periphery of the sleeve 21. The bottoms of the pair of stoppers 25 are fixedly connected to the top of the base 1. A limit block 26 is fixedly connected to the side wall of the sleeve 21, and the limit block 26 is located between the pair of stoppers 25.

[0036] It should be noted that: the limit block 26 fixedly connected to the side wall of the sleeve 21 is limited by a pair of stoppers 25, so as to avoid that when the gear column 23 rotates to drive the sleeve 21 to rotate, the rotation angle is too large, resulting in the gear column 23 disengaging from the arc-shaped rack 24.

[0037] Among them, a column 27 is fixedly connected to the top of the sleeve 21. A sliding cavity 28 is opened in the column 27. A slider 29 is slidably installed in the sliding cavity 28.

A sliding table 33 is slidably connected to the inner wall of the U-shaped frame 31 through the limiting grooves 32. A vertical plate 34 is fixedly connected to the top of the sliding table 33. A first gear 35 is rotatably connected to one side of the vertical plate 34. A C-shaped gear 36 is rotatably connected to the center of one side of the vertical plate 34. The C-shaped gear 36 meshes with the first gear 35. A second gear 37 is fixedly connected to the side wall of the C-shaped gear 36.

[0039] The vertical plate 34 is rotatably connected with a rotating shaft 310, one end of which is fixedly connected with a fourth gear 311, which meshes with the first gear 35, and the other end of the rotating shaft 310 is fixedly connected with a rotating arm 312. A sliding sleeve 313 is vertically arranged at the bottom of the slide 33, and a lifting rod 314 is slidably installed in the sliding sleeve 313. A guide groove body 315 is fixedly connected to the top of the lifting rod 314, and a sliding column 316 is slidably installed in the guide groove body 315, one end of the sliding column 316 is fixedly connected to the side wall of the rotating arm 312, and a limiting ring 317 is fixedly connected to the lifting rod 314.

A pressing plate 319 is fixedly connected to the bottom of the lifting rod 314.

[0040] The top of the slide 33 is fixedly connected to an opening and closing chamber 320, and an air inlet 321 and an air outlet 322 are respectively provided on the opening and closing chamber 320. A piston column 323 is slidably installed in the opening and closing chamber 320. A fixed plate 324 is fixedly connected to the top of the slide 33, and a V-shaped rod 325 is rotatably connected to the fixed plate 324. One end of the piston column 323 is fixedly connected to a hinge seat 326, and a connecting rod 327 is hinged on the hinge seat 326. The other end of the connecting rod 327 is fixedly connected to the hinge seat 326. The end is rotatably connected to one end of the V-shaped rod 325, and a fixed seat 328 is fixedly connected to the top of the slide 33 at a position away from the hinge seat 326. A push rod 329 is slidably connected to the fixed seat 328, and one end of the push rod 329 is fixedly connected to a connecting block 330, and the connecting block 330 is fixedly connected to the side wall of the hinge seat 326. A second spring 331 is sleeved on the outside of the push rod 329, and the two ends of the second spring 331 are fixedly connected to the side walls of the connecting block 330 and the fixed seat 328, respectively.

[0041] It should be noted that a pressure rod 341 is provided on one side of the C-shaped gear 36. When the first gear 35 is located at the starting point of the notch of the C-shaped gear 36, the pressure rod 341 contacts one end of the V-shaped rod 325, causing the V-shaped rod 325 to rotate, thereby pulling the piston column 323 to slide in the opening and closing chamber 320, so that the opening and closing chamber 320 forms a cavity, and the air inlet 321 and the air outlet 322 are connected, so that oxygen can pass through.

[0042] Among them, an installation platform 332 is fixedly connected to the inner wall of the U-shaped frame 31. A third servo motor 333 is fixedly connected to the top of the installation platform 332. The output end of the third servo motor 333 extends out of one side of the U-shaped frame 31 and is fixedly connected to a fifth gear 334. A lead screw 335 is rotatably connected to the inner wall of the U-shaped frame 31. One end of the lead screw 335 extends out of one side of the U-shaped frame 31 and is fixedly connected to a sixth gear 336. The sixth gear 336 meshes with the fifth gear 334.

[0043] Among them, a pair of moving blocks 337 are threadedly connected to the lead screw 335. A pair of chutes 338 are formed in the side wall of the sliding table 33. A pair of translation blocks 339 are slidably installed in each of the pair of chutes 338. A scissor link 340 is provided between the pair of translation blocks 339 and the pair of moving blocks 337. Both ends of one side of the scissor link 340 are respectively rotatably connected to one of the moving blocks 337. Both ends of the other side of the scissor link 340 are respectively rotatably connected to one of the moving blocks 337.

[0044] It should be noted that: the lead screw 335 is provided with two threads in opposite directions, and the two threads are respectively threadedly connected to one of the moving blocks 337. When the lead screw 335 rotates counterclockwise, the pair of moving blocks 337 displace towards the center of the lead screw 335, thereby driving the deformation and extension of the scissor link 340, pushing the sliding table 33 to move away from the lead screw 335, and further synchronously translating the pressing plate 319. During this process, the pair of translation blocks 339 synchronously displace towards the center of the side wall of the sliding table 33 in the chutes 338. When the lead screw 335 rotates clockwise, the scissor link 340 deforms and contracts, pulling the sliding table 33 to drive the pressing plate 319 to move towards the lead screw 335. The cooperation of the above components can horizontally adjust the position of the pressing plate 319, so as to adapt to the usage requirements of patients with different body types.

[0045] Embodiment:

[0046] As Figure 1 - Fig.10 shown, in this embodiment, first, the staff raises the device so that the side rail of the hospital bed is located between the bottom inner wall of the base 1 and the clamping plate 12, and rotates the hexagonal nut 14 to drive the clamping plate 12 to move downward by the screw rod 13, so as to cooperate with the bottom inner wall of the base 1 to clamp the side rail of the hospital bed, and then fix the device on one side of the hospital bed.

[0047] In the standby state of the device: the resuscitation unit 3 is folded on one side of the hospital bed and is parallel to the hospital bed, without affecting the normal rest of the patient.

[0048] When the patient experiences a situation such as respiratory arrest and urgently needs cardiopulmonary resuscitation, the first servo motor 22 fixed to the side wall of the sleeve 21 is activated to rotate the gear column 23. Since the gear column 23 meshes with the arc-shaped rack 24 fixed to the top of the base 1, when the gear column 23 rotates counterclockwise, the first servo motor 22 can drive the sleeve 21 to rotate clockwise on the top of the base 1, and the column 27 fixed to the top of the sleeve 21 rotates synchronously. The rotation of the column 27 drives the slider 29 to rotate synchronously, so that the C-shaped frame 31 drives the pressing plate 319 to move above the hospital bed, that is, above the patient's chest. Subsequently, the third servo motor 333 is activated to rotate the fifth gear 334, driving the sixth gear 336 meshing with it to rotate, causing the lead screw 335 to rotate, and displacing a pair of moving blocks 337 on the lead screw 335, thereby deforming the scissor link 340, pushing or pulling the slide 33 to move along the limit groove 32. The movement of the slide 33 drives the pressing plate 319 to move, so that the pressing plate 319 is located at the precise pressing position on the patient's chest.

[0049] The electric telescopic rod 210 is activated to drag the slider 29 to move downward along the sliding cavity 28, so that the C-shaped frame 31 drives the pressing plate 319 to move downward synchronously until the bottom of the pressing plate 319 fits the patient's chest.

[0050] As can be seen from the above: Through the cooperation of the adjustment mechanism 2 and the resuscitation unit 3, this device can electrically adjust the position of the pressing plate 319 in the horizontal and vertical directions, so as to adapt to patients of different body shapes, making the pressing position precise, avoiding poor cardiopulmonary resuscitation effects caused by deviation of the pressing position. At the same time, the operation steps of this device are simple and convenient for medical staff to use.

[0051] Then, the oxygen mask of the patient is connected to the air outlet 322 of the opening and closing chamber 320 through a pipeline, and the air inlet 321 of the opening and closing chamber 320 is connected to the oxygen tank through a pipeline.

[0052] The second servo motor 38 is activated to rotate the third gear 39, thereby driving the second gear 37 meshing with it to rotate, and further causing the C-shaped gear 36 to rotate. The C-shaped gear 36 drives the first gear 35 meshing with it to rotate, and the rotation of the first gear 35 causes the fourth gear 311 meshing with it to rotate. The rotation of the fourth gear 311 drives the rotating arm 312 connected by the rotating shaft 310 to rotate. When the rotating arm 312 rotates, the sliding column 316 fixedly connected to it slides in the guide groove body 315, and drives the lifting rod 314 to reciprocate up and down in the sliding sleeve 313, thereby driving the pressing plate 319 fixedly connected to the bottom of the lifting rod 314 to press the patient's chest cavity. During the downward pressing process, the first spring 318 is compressed under force.

[0053] When the first gear 35 is located at the starting point of the notch of the C-shaped gear 36, the meshing state of the first gear 35 and the C-shaped gear 36 is released, the first spring 318 rebounds, pushes the lifting rod 314 to drive the pressing plate 319 to move upward, and the pressing stops. At this time, the pressing rod 341 contacts one end of the V-shaped rod 325, and the V-shaped rod 325 rotates at its connection with the fixing plate 324, so that the other end of the V-shaped rod 325 pulls the piston column 323 to slide in the opening and closing chamber 320 through the connecting rod 327. At the same time, the push rod 329 connected on one side slides toward the fixing seat 328 and compresses the second spring 331 sleeved on the outside of the push rod 329, so that the opening and closing chamber 320 forms a cavity, and the air inlet 321 is connected to the air outlet 322, so that oxygen is supplied to the patient, and then artificial respiration is performed on the patient.

[0054] When the first gear 35 is located at the end point of the notch of the C-shaped gear 36, the first gear 35 and the C-shaped gear 36 re-engage, and the pressing continues. At this time, the other end of the V-shaped rod 325 is separated from the pressing rod 341, and the second spring 331 rebounds, thereby pushing the piston column 323 to reset through the push rod 329, and at the same time, the V-shaped rod 325 is reset, and the air supply stops.

[0055] From the above, it can be seen that: through the design of the C-shaped gear 36, the pressing plate 319 will briefly stop pressing the patient's chest after pressing a certain number of times, and at the same time, perform artificial respiration on the patient, thereby cooperating with chest compressions to help the patient restore ventilation function, and then restore the patient's spontaneous circulation and respiratory function.

[0056] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
