Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation machines, in particular to a cardiopulmonary resuscitation machine for medical rescue. Background Art

[0002] Medical rescue cardiopulmonary resuscitation machines, also commonly called CPR devices, are devices that mechanically replace human effort in performing basic life support procedures such as artificial respiration (mechanical ventilation) and chest compressions. They can be divided into two types: electric and pneumatic. These devices provide high levels of uninterrupted artificial circulation and ventilation support. Some portable and transportable CPR machines can be used in pre-hospital emergency care, and their function is not significantly affected even during patient transport.

[0003] CPR machines continuously perform chest compressions on the heart and chest. Existing CPR machines are secured to the patient's body with straps, with the compression plates aligned with the patient's heart and chest. This activates the plates, which then move in a fixed position. The compression area remains constant, preventing comprehensive chest compressions (due to uneven chest and heart conditions), hindering CPR effectiveness. Therefore, we propose a CPR machine for medical rescue. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figures 1-4 The figure shows a cardiopulmonary resuscitation machine for medical rescue, including a body 1, a strap 2 is provided on the body 1, and a pressing plate 3 is movably matched at the bottom of the body 1; it also includes a first gear 4 located in the body 1 and performing circular motion, a movable rod 5 that cooperates with the pressing plate 3 is movably provided on the first gear 4, and a threaded rod 6 is rotatably connected to the body 1; a movable component 7, the movable component 7 is used to drive the first gear 4 to perform circular motion; a reciprocating component 13, the reciprocating component 13 is used to drive the movable rod 5 to perform reciprocating motion; and an adjusting component, the adjusting component is used to drive the movable component 7 to adjust its position through the threaded rod 6.

[0034] See also Figure 5-Figure 7 The movable component 7 shown in the figure includes an inner gear ring 8, a second gear 9 is provided at the central axis of the inner gear ring 8, and multiple first gears 4 are simultaneously engaged with the inner gear ring 8 and the second gear 9. The middle part of one of the first gears 4 is rotatably connected to a rotating plate 10, and the movable rod 5 is obliquely distributed and passes through the rotating plate 10. A power component 18 is provided in the body 1 to drive the second gear 9 to rotate.

[0035] See also Figure 6-Figure 7 The movable component 7 shown in the figure also includes a limiting ring plate 11 fixedly connected to the inner gear ring 8 and movably matched with the first gear 4, and the top and bottom surfaces of the second gear 9 are fixedly connected to a limiting circular plate 12 that matches the first gear 4.

[0036] See also Figure 5 and Figures 9-12The reciprocating assembly 13 shown in the figure includes a movable ring plate 14 that is pressed against the movable rod 5. The central axis of the limiting circular plate 12 located at the lower position is fixedly connected to a connecting rod 15. The bottom end of the connecting rod 15 is rotatably connected to a rotating plate 16. The bottom end of the movable rod 5 passes through the rotating plate 16. The movable rod 5 and the pressing plate 3 are movably connected through an embedded rotating ball. A plurality of elastic pull ropes 17 are hung between the rotating plate 16 and the pressing plate 3. The movable ring plate 14 is moved by a power assembly 18. The top of the movable rod 5 is fixedly connected to a pressing ball 31 that is pressed against the movable ring plate 14.

[0037] In this embodiment, the body 1 is fixed to the patient's body by the strap 2, and the initial position of the pressing plate 3 is adapted to the patient's heart and chest position. By starting the power assembly 18, the inner gear ring 8 remains in place, the second gear 9 rotates, and drives the first gear 4 to rotate. The first gear 4 then performs a circular motion along the inner gear. The first gear 4 in circular motion drives the movable rod 5 to perform a circular motion. The rotating plate 16 rotates adaptively to coordinate with the circular motion of the movable rod 5 and the pressing plate 3. In conjunction with the reciprocating assembly 13, the pressing position of the pressing plate 3 on the heart and chest is changed, thereby ensuring that the pressing plate 3 comprehensively compresses all positions of the heart and chest.

[0038] Under the action of the power component 18, the movable ring plate 14 moves back and forth, thereby pressing the pressing ball 31, and the movable rod 5 that performs circular motion cooperates with the elastic pull rope 17 to move up and down along the rotating plate 10, so that the pressing plate 3 that performs circular motion moves back and forth up and down, thereby comprehensively pressing various positions of the heart and chest, and the movable rod 5 is in an inclined state, so that the angle of the pressing force is in an inclined direction, which is conducive to the action of the pressing plate 3 on the convex heart and chest (the surface of the heart and chest is not flat, but convex), which helps to ensure the pressing and resuscitation effect of the pressing plate 3 on the heart and chest position.

[0039] Example 2

[0040] This second embodiment is a further supplement and explanation of the first embodiment. Figure 9-10 The power assembly 18 shown in the figure includes a motor 19 fixedly connected to the body 1, the output shaft of the motor 19 is fixedly connected to the rotating rod 20, the bottom end of the rotating rod 20 is fixedly connected to the first telescopic rod 21 with a first elastic puller inside, and a sliding groove 22 is provided on the limiting circular plate 12 located at the upper position, and a sliding plate 23 rotatably connected to the end of the first telescopic rod 21 is slidably fitted in the sliding groove 22.

[0041] See also Figure 6-Figure 8The power assembly 18 shown in the figure also includes a rotating drum 24 connected and fixed to the rotating rod 20, and a wavy limiting groove 25 is provided on the rotating drum 24, and a sliding column 26 is slidably fitted in the limiting groove 25. A limiting splint 27 is fixedly connected to the body 1, and a slide plate 28 connected and fixed to the movable ring plate 14 is slidably fitted on the limiting splint 27, and the slide plate 28 is fixedly connected to the sliding column 26.

[0042] In this embodiment, the motor 19 is started, driving the rotating rod 20 to rotate, driving the first telescopic rod 21 to rotate, and under the action of the sliding groove 22 and the sliding plate 23 (the sliding plate 23 slides adaptively in the sliding groove 22), the second gear 9 rotates. Under the action of the limiting circular plate 12 and the plurality of first gears 4, the position of the second gear 9 relative to the inner gear ring 8 remains unchanged. The first telescopic rod 21 is provided with a first elastic puller to ensure that the sliding plate 23 does not disengage from the sliding groove 22.

[0043] The rotation of the rotating rod 20 drives the rotating drum 24 to rotate. Under the action of the slide plate 28 and the limit clamping plate 27, the slide bar moves up and down, thereby causing the slide plate 28 and the movable ring plate 14 to move back and forth.

[0044] Example 3

[0045] This third embodiment is a further supplement and explanation of the second embodiment. Figure 2-Figure 3 The adjustment assembly shown in the figure includes two moving rods 29 connected and fixed to the inner gear ring 8. The moving rods 29 move horizontally in the body 1. One of the moving rods 29 is threadedly connected to the threaded rod 6 that penetrates into the body 1. The cross-section of the moving rod 29 is a rectangular structure.

[0046] See also Figure 10-12 The adjustment assembly shown in the figure also includes a second telescopic rod 30 with a second elastic puller inside. One end of the second telescopic rod 30 is L-shaped and is fixedly connected to the rotating plate 10. The other end of the second telescopic rod 30 is rotatably connected to the connecting rod 15.

[0047] In this embodiment, when the position of the pressing plate 3 that performs circular motion and reciprocating pressing motion needs to be adjusted, by rotating the threaded rod 6, the threaded rod 6 causes the movable rod 29 to drive the inner gear ring 8 to perform horizontal movement, and the first gear 4 and the second gear 9 as well as the movable rod 5 and the rotating plate 16 all move accordingly. The position of the rotating rod 20 remains unchanged, and the first telescopic rod 21 and the second telescopic rod 30 perform adaptive telescopic motion. Under the action of the elastic puller, the rotating rod 20 that rotates itself ensures that the second gear 9 and the first gear 4 perform circular motion after the position is adjusted, and the movable rod 5 and the pressing plate 3 perform reciprocating motion while performing circular motion after the position is adjusted, so as to perform a more comprehensive resuscitation operation on the heart and chest position. The threaded action of the threaded rod 6 prevents the threaded rod 6 from reacting to the internal activity, causing the threaded rod 6 to rotate automatically.
