Wherein, the support rod 13 and the pushing rod 11 are distributed in an intersecting way, namely, the axis of the support rod 13 and the axis of the pushing rod 11 are arranged in an intersecting way. The support rod 13 and the pushing rod 11 may be hollow structures or solid structures, which is not limited in the embodiment of the present invention. One end of the supporting rod 13 is connected with the pressing head 12, the other end of the supporting rod 13 is connected with the pushing rod 11, a T-shaped rod-shaped structure is formed between the supporting rod 13 and the pushing rod 11, a pushing force application point is further provided through the pushing rod 11, and a pressing force application point is provided through the pressing head 12.

In order to facilitate the holding operation by two hands of the operator, the pressing handle 14 may include a first handle and a second handle, and the first handle and the second handle are symmetrically distributed with the axis of the supporting rod 13 as a symmetry axis. The distance between the pressing handle 14 and the pressing head 12 is greater than the distance between the pressing handle 14 and the pressing rod 11, and the distance between the pressing handle 14 and the pressing rod 11 is determined according to the length of the arm of the operator. In some embodiments, the distance between the compression handle 14 and the push rod 11 may be an average of the length of the operator's arm, so that the cardiopulmonary resuscitation compressor may accommodate most of the operator's operational needs. In other embodiments, the distance between the pressing handle 14 and the pushing rod 11 can be adjusted according to operators with different arm lengths, so as to give the operators the best operation experience.

In summary, the cardiopulmonary resuscitation pressing device provided by the embodiment of the present invention is not only simple and convenient to operate, but also beneficial to reducing the fatigue of the operator, and further beneficial to the use of the cardiopulmonary resuscitation pressing device in an emergency state.

In some embodiments, the support rods 13 are adjustable in length to accommodate different arm lengths for operation by operators.

Alternatively, the support rod 13 is a telescopic rod so that the distance between the pressing handle 14 and the pushing rod 11 is adjustable.

Thus, the length of the support rod 13 can be adjusted, and the distance between the pressing grip 14 and the pressing rod 11 can be adjusted according to the arm length of the operator.

Further, as shown in fig. 1, the support rod 13 includes a support main rod 131 and a support sub-rod 132; the first end of the main supporting rod 131 is connected with the pressing head 12, the other end of the main supporting rod 131 is movably connected with the first end of the auxiliary supporting rod 132, and the second end of the auxiliary supporting rod 132 is connected with the pushing rod 11. It should be noted that, since the other end of the main support rod 131 is movably connected to the first end of the auxiliary support rod 132, the length of the support rod 13 can be adjusted, and the distance between the pressing handle 14 and the pushing rod 11 can be changed. The movable connection between the main support rod 131 and the auxiliary support rod 132 may be a threaded connection, a sliding connection realized in a clamping manner, or other connection manners, which is not limited in this embodiment of the application.

In some embodiments, the main support rod 131, the pressing handle 14 and the auxiliary support rod 132 are all tubular rods, and the cpr pressing device further comprises a driving module 2; the driving module 2 comprises a first motor 21, a main bevel gear 22, an auxiliary bevel gear 23 and a long screw 24; the first motor 21 is arranged in the inner cavity of the pressing handle 14, the driving shaft of the first motor 21 is connected with the main bevel gear 22, the main bevel gear 22 is meshed with the auxiliary bevel gear 23, and the long screw 24 is in threaded connection with the first end of the supporting auxiliary rod 132; when the first motor 21 rotates in the first direction, the distance between the pressing handle 14 and the pressing rod 11 increases; when the first motor 21 rotates in a second direction, which is opposite to the first direction, the distance between the pressing handle 14 and the pressing rod 11 decreases.

It should be noted that the driving shaft of the first motor 21 intersects with the long screw 24, the driving shaft of the first motor 21 is connected with the main bevel gear 22, the main bevel gear 22 is engaged with the auxiliary bevel gear 23, and the long screw 24 is in threaded connection with the first end of the supporting auxiliary rod 132, so that under the condition that the driving shaft of the first motor 21 rotates, the main bevel gear 22 can be driven to rotate, and the main bevel gear 22 rotates to drive the auxiliary bevel gear 23 to rotate, so as to further enable the long screw 24 to rotate. Further, since the long screw 24 is screwed to the first end of the sub-support rod 132, the distance between the pressing handle 14 and the pressing rod 11 can be changed.

Specifically, when the distance between the pressing handle 14 and the pushing rod 11 needs to be increased, the driving shaft of the first motor 21 can be rotated in the first direction, and then under the action of the driving shaft, the main bevel gear 22 is rotated in the first direction, the auxiliary bevel gear 23 is rotated under the action of the main bevel gear 22, so that the long screw 24 is rotated in the clockwise direction, and then the length of the threaded connection between the long screw 24 and the first end of the supporting auxiliary rod 132 is reduced, and further the distance between the pressing handle 14 and the pushing rod 11 is increased. When the distance between the pressing handle 14 and the pushing rod 11 needs to be increased and decreased, the driving shaft of the first motor 21 can be rotated according to the second direction, and then under the action of the driving shaft, the main bevel gear 22 is rotated according to the second direction, the auxiliary bevel gear 23 is rotated under the action of the main bevel gear 22, so that the long screw 24 is rotated according to the counterclockwise direction, and then the length of the threaded connection between the long screw 24 and the first end of the supporting auxiliary rod 132 is increased, and further the distance between the pressing handle 14 and the pushing rod 11 is decreased. Thus, when operators on different arms use the device, the distance between the pressing handle 14 and the pushing rod 11 can be controlled by controlling the rotation of the first motor 21 so as to adapt to the use requirements of different operators. It should be noted that the first direction and the second direction are opposite directions, for example, the first direction is a clockwise direction, and the second direction is a counterclockwise direction.

It should be noted that two height-adjusting buttons may be provided on the bottom surface of the pressing handle 14 near the support main rod 131, and the height-adjusting buttons may be installed at positions such that the index finger of the rescuer can directly perform the pressing operation when holding the pressing handle 14. One of the height-adjustment buttons is used to control the first motor 21 to rotate in a first direction to raise the support sub-lever 132, and the other is used to control the first motor 21 to rotate in a second direction to lower the support sub-lever 132.

Further, as shown in fig. 3, the cardiopulmonary resuscitation pressing device includes an auxiliary bevel gear 25 and a short shaft 26; the end of the short shaft 26 is connected with an auxiliary bevel gear 25, and the auxiliary bevel gear 25 is meshed with the auxiliary bevel gear 23; in the case where the stub shaft 26 rotates, the auxiliary bevel gear 25 rotates the auxiliary bevel gear 23.

The stub shaft 26 is inserted into the support main rod 131 through a bearing, and a rotation groove for the auxiliary bevel gear 25 is provided inside an end portion of the stub shaft 26. Further, a Z-shaped handle may be detachably attached to the inside of the push rod 11. Since the auxiliary bevel gear 25 is engaged with the sub bevel gear 23, when it is necessary to change the distance between the push handle 14 and the push rod 11, the Z-shaped handle can be inserted into the rotary groove, and the sub bevel gear 23 can be rotated by the rotation of the auxiliary bevel gear 25, whereby the distance between the push handle 14 and the push rod 11 can be adjusted. Thus, the distance between the complete pressing handle 14 and the push rod 11 can be manually adjusted in the above way, so that the cardiopulmonary resuscitation pressing device can be normally used even under the condition of no power supply.

For the supporting main rod 131, the supporting main rod 131 may be a straight rod, a bent rod, or a multi-section rod with a certain angle, which is not limited in the embodiment of the present invention.

The two auxiliary levers 15 positioned at both sides of the supporting main lever 131 are eccentrically coupled to both end surfaces of the worm wheel 34, respectively. In this way, in the case that the driving shaft of the second motor 32 is rotated, the two auxiliary levers 15 positioned at both sides of the supporting main lever 131 are rotated following the worm wheel 34 and positionally moved at the position where they are eccentrically rotated, thereby being adapted to the thickness of the wrist of the operator to be more convenient for the operator to use.

The metal block 5 may be a block or spherical metal that can reflect ultrasonic waves, such as a lead block, a copper block, and an iron block, which is not limited in the embodiment of the present invention. The metal block 5 is arranged in the middle of the pressing plate 4, so that the metal block 5 and the cardiopulmonary resuscitation pressing point of the rescued person are in opposite positions when in use, namely a connecting line between the metal block 5 and the ranging sensor is vertical to the plane of the pressing plate 4.

Alternatively, the pressing plate 4 includes a pressing plate main body 41, a partition plate 42, and a movable plate 43; the partition plate 42 is positioned in the middle of the pressing plate body 41, and a sliding groove 512 is formed at the edge position between the partition plate 42 and the two sides of the pressing plate body 41; both ends of the movable plate 43 are slidably coupled to the sliding grooves 512, and the metal block 5 is fixed to the middle of the sliding plate.
