Technical Field
[0001] This invention relates to the field of emergency rescue device technology, specifically a Heimlich maneuver device for children. Background Technology
[0002] When a foreign object obstructs the airway, the patient is in an extremely dangerous state due to respiratory failure, requiring immediate Heimlich maneuver to clear the airway and relieve the emergency. Current Heimlich maneuvers require professional medical personnel to perform, and the lack of such personnel or their absence on-site increases the difficulty of saving the patient. To address this, machines for performing the Heimlich maneuver have been developed, but they still have the following problems: existing Heimlich maneuvers cannot perform back blows, and the existing chest compression components rely on gears rotating to push against a lever, with a limited stroke that fails to generate effective impact force. Summary of the Invention
[0003] The purpose of this invention is to provide a Heimlich maneuver device for children to solve the problems mentioned in the background art.
[0004] One technical solution provided by this invention is: a Heimlich maneuver device for children, comprising: A base, on which a support frame is fixed; A back-patting assembly is disposed on the stand and configured to be adjusted up and down along the stand.

The compression assembly is connected to the stand via an arc-shaped arm. The arc-shaped arm is adjustable in height on the stand. The compression assembly includes a force-applying part and an actuating part. The actuating part is fixed at the position of the arc-shaped arm facing the patient's chest and abdomen. The force-applying part is fixed to the stand or base. The force-applying part drives the actuating part to reciprocately compress the patient's chest and abdomen.
[0005] The beneficial effects of the above technical solution are as follows: the back-slapping and compression components allow for compression of the patient's chest and abdomen, and slapping of the patient's back. This is more in line with the new Heimlich maneuver guidelines. The adjustable curved arm height accommodates people of different heights, and its ease of operation allows for its use by a wider range of people.
[0006] Furthermore, the actuation unit includes a telescopic cylinder for performing the action. The telescopic cylinder is arranged on the arc-shaped arm, and a compression head is connected to the outside of the telescopic cylinder. The force application unit includes a shaft for compressing a hydraulic pipe. The end of the hydraulic pipe away from the shaft is connected to the telescopic cylinder. The shaft is set to a reciprocating sliding state, and a motor is connected to the end away from the hydraulic pipe. A crank and a connecting rod are also connected between the motor and the shaft.
[0007] Furthermore, the back-patting assembly includes a patting plate and a drive assembly for reciprocating the patting plate. The patting plate's movement direction is limited to a straight line toward the patient's back by a limiting frame. The drive assembly includes a motor and a crank, with the crank connected to the patting plate via a connecting rod.
[0008] Furthermore, the stand is provided with a shoulder bracket for fixing the patient's shoulder.

Detailed Implementation
[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] like Figure 1-7 As shown, this embodiment provides a Heimlich maneuver device for children, including a base 200 and a stand 100. The stand 100 is fixed to the base 200, which serves to fix the stand 100 and also as a platform for the patient to stand on. To expel foreign objects from the patient's airway, a back-slapping component is installed on the stand 100 corresponding to the patient's back, and a compression component is installed on the stand 100 corresponding to the patient's chest and abdomen. The compression component is connected to the stand 100 via an arc-shaped arm 300. The cavity formed by the arc-shaped arm 300 is used to accommodate the patient's body, allowing the compression component to connect to the stand 100 without affecting the patient's standing position. Specifically, the arc-shaped arm 300 includes a horizontal section and a mounting section 310. The horizontal section extends horizontally forward from the outside of the stand 100 to the side in front of the patient. The mounting section 310 is connected to the horizontal section and extends from the side in front of the patient to directly in front of the patient. Thus, by placing the compression component on the mounting section 310, compression can be applied to the patient's chest and abdomen. Furthermore, the horizontal section can be arc-shaped.
[0018] The compression component allows for chest and abdominal compression, while the back-slapping component allows for back slapping. This aligns better with the new Heimlich maneuver guidelines. The adjustable curved arm accommodates individuals of varying heights and is easy to use, making it accessible to a wider range of users. Specifically, first, use the back-slapping component to slap the patient's back several times, then use the compression component to compress the chest and abdomen.
[0019] In some embodiments, the compression assembly includes a force-applying part and an actuating part. The force-applying part is disposed on a base 200 or a stand 100, preferably on the stand 100. The force-applying part and the actuating part are connected by a hydraulic pipe 611. The actuating part includes a telescopic cylinder 610 for performing the action. The telescopic cylinder 610 is disposed on an arc-shaped arm 300. A compression head 600 is externally connected to the telescopic cylinder 610. The compression head 600 includes a rigid support block. A flexible layer, such as a rubber layer, is attached to the side of the support block facing the patient. The flexible layer can be configured in an arc-shaped convex state. The force-applying part includes a shaft for compressing the hydraulic pipe 611. The shaft is configured to reciprocate and slide. A motor is drivenly connected to the end away from the hydraulic pipe 611. A crank and a connecting rod are also connected between the motor and the shaft. One end of the connecting rod is hinged to the shaft, and the other end is hinged to the crank. The end of the crank away from the connecting rod is connected to the motor shaft. The motor drives the shaft to reciprocate via a crank-connecting rod mechanism, applying pulsed pressure to the hydraulic tube 611. This, in turn, drives the compression head 600 to reciprocate, compressing the patient's chest and abdomen to perform the Heimlich maneuver. To guide the compression head 600 to apply force in an upward-tilting direction, an inclined surface is constructed on the mounting section 310. The telescopic cylinder 610 is fixed to this inclined surface, ensuring that the compression head compresses the patient's chest and abdomen at an upward tilt during operation.
[0020] Furthermore, a slider can be arranged between the connecting rod and the shaft. The slider is hinged to the connecting rod, and the slider moves in the same direction as the shaft. The slider and the shaft are not connected. When the slider is driven forward by the connecting rod, it pushes the shaft to do work. When the slider is driven backward by the connecting rod, it disengages from the shaft, and the shaft resets itself.
[0021] Furthermore, to enhance safety, a power box 620 is installed on the support frame 100. The power box 620 has a cavity for accommodating the force-applying part, and a hole is provided on the power box 620 for the hydraulic pipe 611 to extend out. The hydraulic pipe 611 is filled with hydraulic oil, which transmits the movement of the shaft to the telescopic rod of the power part, thereby driving the extrusion head 600 to move.
[0022] In some embodiments, the back-tapping assembly includes a tapping plate 410 and a drive assembly for driving the tapping plate 410. The drive assembly can drive the tapping plate 410 to reciprocate to achieve tapping on the patient's back. Specifically, the drive assembly includes a motor and a crank, the crank being connected to the tapping plate 410 via a connecting rod. One end of the connecting rod is connected to the tapping plate 410, and the other end is hinged to the crank, which is connected to the motor shaft. To limit the movement of the tapping plate 410, a limiting frame 400 is also included. The limiting frame 400 has a through hole facing the patient. The tapping plate 410 is slidably disposed in the through hole via a connecting rod, one end of which is fixed to the tapping plate 410, and the other end of which is hinged to the connecting rod. The limiting frame 400 is preferably a housing, the drive assembly being fixed inside the housing, and the through hole being located on the outer wall of the housing.
[0023] In some embodiments, to guide the patient to maintain a standing position, a shoulder support is also provided on the support frame 100 to fix the patient's shoulders. The shoulder support includes two arc-shaped frames 500 adapted to the shape of the shoulders, and the two arc-shaped frames 500 are spaced apart to fit the two shoulder parts of the human body. The two arc-shaped frames 500 are connected to the support frame 100 by cantilever 510. To accommodate people of different heights, the cantilever 510 is configured to slide in contact with the support frame 100.
[0024] Furthermore, to make the overall structure more compact, the cantilever 510 and the backplate assembly are connected together to achieve synchronous lifting. Specifically, a slide 420 for connecting the cantilever 510 is provided on the frame 100. The backplate assembly can be directly connected to the cantilever 510 via a hanger 430, or it can be connected to the slide 420 via the hanger 430. A slide groove 110 for assembling the slide 420 is provided on the frame 100. The slide groove 110 is opened along the length of the frame 100, and the length of the slide groove 110 is adapted to the adjustment range of the shoulder bracket.
[0025] See Figure 3 , 67. Furthermore, to make the lifting and lowering of the cantilever 510 and the back-bearing assembly more effortless, a first counterweight 700 is slidably mounted on the frame 100. The first counterweight 700 is assembled in a vertical groove 120, and is spaced apart from the slide groove 110. The movement path of the first counterweight 700 is parallel to the slide groove 110. The upper part of the installation space of the slide groove 110 and the first counterweight 700 is connected, and a fixed pulley is arranged at the connection position. The suspension rope 710 of the first counterweight 700 passes around the fixed pulley and connects to the slide base 420. After adjusting the cantilever 510 and the back-bearing assembly into position, they also need to be fixed in the adjusted position. Specifically, there are spaced slots 111 on both sides of the slide groove 110. The opening of the slots 111 faces the slide base 420, and the distance between adjacent slots 111 is the minimum adjustable distance of the slide base 420. To facilitate the fixation of the slide 420 via the slot 111, retractable latches 421 are provided on both sides of the slide 420. The latches 421 are held extended by springs and engage with a specific slot 111 after extension, thus fixing the slide 420 in its current position. When the position of the slide 420 needs adjustment, it can be moved to its interior. Specifically, a handle 511 for driving the latches 421 is provided on the cantilever 510. The handle 511 is rotatably mounted on the cantilever 510 and connected to the two latches 421 via a cable 514. Pressing the handle 511 retracts the two latches 421 into the slide 420, and releasing the handle 511 allows the latches 421 to be pushed out of the slide 420 again by the springs. During operation, holding the handle 511 with one hand unlocks the slide 420 and simultaneously adjusts the cantilever 510 into position. Two latches 421 are connected to the pull cable 514 via two branch lines 515. To assist in the reset of the handle 511, a reset spring is provided between the handle 511 and the cantilever 510. Upon release, the reset spring drives the handle 511 to reset. Simultaneously, the spring in the latches 421 also assists in the reset of the handle 511.
[0026] See Figure 6Furthermore, for convenient operation of the handle 511, a protective ring 512 is also provided on the cantilever 510. The handle 511 is hinged to the inside of the protective ring 512, which is formed by bending a hollow tube. The hinge point of the handle 511 is close to the left side of the handle, and the handle 511 extends towards the cantilever 510 when no external force is involved. When it is necessary to press the handle 511, the operator's palm presses against the outside of the protective ring 512, and the fingers bend and extend into the protective ring to squeeze the handle. The pull cable 514 is connected to the left side of the hinge point of the handle 511. The protective ring 512 has a hole for the pull cable 514 to pass through, and the cantilever 510 also has a channel 513 for the pull cable 514 to pass through. One end of the channel 513 communicates with the inside of the protective ring 512, and the other end extends to the slide 420. An auxiliary channel communicating with the channel 513 is constructed in the slide 420, and a branch line 515 is arranged in the auxiliary channel.
[0027] See Figure 3 In some embodiments, to facilitate smooth adjustment of the arc-shaped arm 300, a lifting groove 130 is provided on the side of the support frame 100. A sliding body 320 is slidably disposed within the lifting groove 130 at the end of the arc-shaped arm 300. The sliding body 320 moves up and down within the lifting groove 130 to drive the arc-shaped arm 300 to rise and fall. Furthermore, to save effort, a second counterweight 800 is also provided on the support frame 100. The second counterweight 800 moves vertically on the support frame 100. The second counterweight 800 and the sliding body 320 are connected by a cable 810. Fixed pulleys are arranged on the support frame 100 at the turning points corresponding to the path connecting the second counterweight 800 and the sliding body 320.
[0028] See Figure 4-5Furthermore, in order to engage the arc-shaped arm 300 in the moved position, adjustment notches 131 are arranged on both sides of the lifting groove 130, with the adjustment notches 131 facing the sliding body 320. Locking lugs 321 extending into the adjustment notches 131 are provided on both sides of the sliding body 320. The locking lugs 321 extend out of the sliding body 320 under the action of a spring, and external force can retract the locking lugs 321 back into the sliding body 320. Specifically, a sliding hole for accommodating the locking lugs 321 is constructed on the side of the sliding body 320, and the spring driving the locking lugs 321 is arranged within the sliding hole. A pressure handle 301 is also provided on the arc-shaped arm 300. The pressure handle 301 is rotatably mounted on the arc-shaped arm 300. The pressure handle 301 pulls two latches 321 via a pull line. Specifically, the two latches are connected to the pull line via branch lines. Pressing the pressure handle 301 retracts the two latches 321 into the sliding body 320. Releasing the pressure handle 301 allows the latches 321 to extend out of the sliding body 320 again. Specifically, a grip ring 302 is provided on the arc-shaped arm 300. The pressure handle 301 is hinged to the inner side of the grip ring 302. The grip ring 302 is formed by bending a hollow tube. The hinge point of the pressure handle 301 is near the left side of the pressure handle 301. When no external force is involved, the pressure handle 301 extends towards the arc-shaped arm 300. When it is necessary to press the pressure handle 301, the operator's palm presses against the outer side of the grip ring 302, and the fingers bend and extend into the grip ring 302 to squeeze the pressure handle 301 tightly. The pull cable 304 is connected to the left side of the hinge point of the pressure handle 301. The grip ring 302 has a hole for the pull cable 304 to pass through. The arc arm 300 also has a channel 303 for the pull cable 304 to pass through. One end of the channel 303 is connected to the inside of the grip ring 302, and the other end extends to the sliding body. A branch channel connected to the channel 303 is constructed in the sliding body, and the branch line 305 is arranged in the auxiliary channel.
