Description

Technical Field

[0001] This utility model belongs to the field of cardiac compression machine technology, and in particular relates to an animal cardiac compression machine. Background Technology

[0002] Animal cardiopulmonary resuscitation (CPR) machines are basic life support equipment for animal cardiopulmonary resuscitation. They use machinery to replace human labor to perform chest compressions on animals, restore blood circulation, and re-establish the animal's spontaneous heartbeat. Such equipment can provide a high level of uninterrupted artificial circulation, greatly improving the survival rate of critically ill animals in emergency care.

[0003] However, due to the wide variety of animal species, the chest cavity height and compression depth vary greatly among individuals, and the chest cavities of small and medium-sized animals are generally quite soft. Existing animal cardiopulmonary resuscitation (CPR) machines do not have adjustable compression depth, making it difficult to match the compression depth with the animal, resulting in poor blood circulation, low survival rate in emergency care, and high risk of sequelae after rescue.

Detailed Implementation

[0026] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] like Figures 1 to 6As shown, one embodiment of this utility model provides an animal heart compression machine, including a rescue table 1, a frame 5, a compression head 15, a depth adjustment component, and a drive device. The frame 5 is mounted on the rescue table 1, the drive device is mounted on the frame 5, and the compression head 15 is connected to the drive device. The drive device is used to drive the compression head 15 to move downward so that the compression head 15 can perform heart compressions on the animal placed on the rescue table 1. The depth adjustment component is used to adjust the downward stroke of the compression head 15.

[0028] In one embodiment, the driving device includes a power unit 9, a drive shaft 11, and an eccentric wheel 10. The power unit 9 is connected to the frame 5. One end of the drive shaft 11 is connected to the power unit 9, and the other end of the drive shaft 11 is connected to the eccentric wheel 10. The power unit 9 drives the eccentric wheel 10 to rotate through the drive shaft 11.

[0029] The frame 5 is provided with a mounting base 12, and the mounting base 12 has a through hole 13. The pressing head 15 includes an elastic element 17, a rod 16 slidably assembled in the through hole 13, and a stop 38 connected to the rod 16. The elastic element 17 is connected between the mounting base 12 and the stop 38. The elastic element 17 can drive the stop 38 to move upward by its own elastic force, so that the top end of the rod 16 abuts against the wheel surface of the eccentric wheel 10. When the eccentric wheel 10 rotates, it forces the rod 16 to move downward. The depth adjustment component changes the distance by which the eccentric wheel 10 forces the rod 16 to move downward by adjusting the distance between the axis of the drive shaft 11 and the wheel surface of the eccentric wheel 10 on the side away from the drive shaft 11. A bushing 14 is provided in the through hole 13 of the mounting base 12, and the rod 16 is fitted into the bushing 14.

[0030] Specifically, the elastic element 17 is a spring fitted onto the rod 16. The upper end of the spring is connected to the stop platform, and the lower end of the spring is connected to the mounting base 12. The position where the drive shaft 11 is connected to the eccentric wheel 10 is such that there is a certain distance between the axis of the drive shaft and the center of the eccentric wheel 10. Therefore, when the power unit 9 drives the eccentric wheel 10 to rotate, when the wheel surface of the eccentric wheel 10 away from the drive shaft 11 abuts against the rod 16, the wheel surface of the eccentric wheel 10 forces the rod 16 to move downward so that the bottom end of the rod 16 presses against the animal's heart. At this time, the spring is compressed. When the wheel surface of the eccentric wheel 10 close to the drive shaft 11 abuts against the rod 16, under the elastic force of the spring, the stop platform 38 drives the rod 16 to move upward, so that the bottom end of the rod 16 moves away from the animal.

[0031] In one embodiment, the lower end of the rod 16 is provided with a rubber head 39, which can play a buffering role.

[0032] In one embodiment, the frame 5 includes a mounting frame 7 and a lifting frame 6. The upper end of the lifting frame 6 is connected to the mounting frame 7, and the lower end of the lifting frame 6 is connected to the emergency station 1. The power unit 9 and the mounting base 12 are mounted on the mounting frame 7.

[0033] The mounting bracket 7 is provided with multiple mounting holes 8. The power unit 9 is specifically a drive motor. The drive shaft 11 is connected to the output shaft of the drive motor. The drive motor drives the drive shaft 11 to rotate, thereby causing the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, it drives the pressing head 15 to press the animal.

[0034] By bolting the drive motor and the mounting base 12 onto different mounting holes 8, the positions of the power unit 9 and the mounting base 12 are changed, thereby adjusting the pressing position of the pressing head 15 to suit different types of animals.

[0035] The lifting frame 6 includes a lifting base 29 and a lifting plate 32. The lower end of the lifting base 29 is mounted on the emergency table 1. The lifting base 29 is provided with a lifting groove 30 extending in the vertical direction. The lower part of the lifting plate 32 is inserted into the lifting groove 30, and the lifting plate 32 can slide up and down in the lifting groove 30. The lifting groove 30 is provided with an elongated hole 31, and the lifting plate 32 is provided with a round hole 33. A locking rod 34 is inserted into the round hole 33 and the elongated hole 31. One end of the locking rod 34 is provided with a locking plate 35, and the other end is provided with a rotating shaft 36. A pawl 37 is rotatably mounted on the rotating shaft 36. When the pawl 37 abuts against the lifting base 29, it can lock the lifting plate 32 onto the lifting base 29. When the pawl 37 rotates away from the lifting base 29, the pawl 37 is lifted. At this time, the height of the lifting plate 32 can be adjusted.

[0036] In one embodiment, the depth adjustment assembly includes an elongated insertion hole 22 disposed on the eccentric wheel 10, the elongated insertion hole 22 extending along the diameter of the eccentric wheel 10, the center of the elongated insertion hole 22 being concentrically disposed with the wheel center of the eccentric wheel 10, and one end of the drive shaft 11 near the eccentric wheel 10 being inserted into the elongated insertion hole 22.

[0037] In one embodiment, the elongated insertion hole 22 has a plurality of slots 23 on the side facing the drive shaft 11, and the plurality of slots 23 are arranged at intervals along the length direction of the elongated insertion hole 22. The depth of the slots 23 is less than the depth of the elongated insertion hole 22, and they are only provided on the side of the elongated insertion hole 22 facing the power unit 9.

[0038] The drive shaft 11 is provided with an insertion end 24 near the eccentric wheel 10. The length of the insertion end 24 is greater than or equal to the depth of the elongated insertion hole 22. The insertion end 24 includes a connected insertion part 26 and a moving part 25. The moving part 25 is disposed near the eccentric wheel 10. The insertion part 26 is provided with an insertion block 27. The moving part 25 can move in the elongated insertion hole 22 so that the insertion block 27 can be inserted into the slot 23 at different positions in the elongated insertion hole 22.

[0039] Specifically, the eccentric wheel 10 can be pulled away from the drive shaft 11. When the eccentric wheel 10 is pulled, the slot 23 on the eccentric wheel 10 disengages from the insert 27 on the drive shaft 11. At this time, the eccentric wheel 10 can be moved up and down according to the type of animal. When the eccentric wheel 10 is moved to a suitable position, it is pushed towards the power unit 9, so that the insert 27 on the drive shaft 11 is inserted into the slot 23 in the elongated insertion hole 22, thus connecting the drive shaft and the eccentric wheel 10, so that the eccentric wheel 10 is driven to rotate when the drive shaft 11 rotates. In addition, during the up and down movement of the eccentric wheel 10, under the elastic force of the spring, the top of the rod 16 can always abut against the wheel surface of the eccentric wheel 10, preventing the rod 16 from disengaging from the eccentric wheel 10.

[0040] In one embodiment, the eccentric wheel 10 is provided with a scale 21 on the side facing away from the power unit 9. The scale 21 is arranged along the length direction of the elongated insertion hole 22. The insertion end 24 is provided with an arrow 28 on the end face facing away from the power unit 9. The arrowhead of the arrow 28 points to the scale 21 to indicate the distance between the axis of the drive shaft 11 and the wheel surface of the eccentric wheel 10 on the side away from the drive shaft 11.

[0041] The scale 21 extends vertically and is marked with numbers. Each number represents a specific distance between the axis of the drive shaft 11 and the wheel surface of the eccentric wheel 10 on the side away from the drive shaft 11. The distance between the axis of the drive shaft 11 and the wheel surface of the eccentric wheel 10 on the side away from the drive shaft 11 can be adjusted according to the specific species of animal.

[0042] In one embodiment, the top end of the rod 16 is provided with an auxiliary wheel 19, which abuts against the wheel surface of the eccentric wheel 10. The top end of the rod 16 is also provided with two auxiliary wheel supports 18, which are arranged opposite to each other. An axle is provided between the two auxiliary wheel supports 18, and the auxiliary wheel 19 is rotatably mounted on the axle. Compared to the direct contact between the top of the rod 16 and the wheel surface of the eccentric wheel 10, the friction between the auxiliary wheel 19 and the eccentric wheel 10 is rolling friction, resulting in lower frictional force. This avoids interference between the rod 16 and the eccentric wheel 10 and also prevents the rod 16 from damaging the eccentric wheel 10.

[0043] In one embodiment, the eccentric wheel 10 has a wheel rail 20 on its surface, and the auxiliary wheel 19 is mounted in the wheel rail 20. The width of the auxiliary wheel 19 is adapted to the width of the wheel rail 20. The auxiliary wheel 19 rolls in the wheel rail 20, which can limit the movement of the auxiliary wheel 19 and prevent it from disengaging from the eccentric wheel 10.

[0044] In one embodiment, the first aid station 1 is provided with a fixing post 3 for fixing animal limbs, and the position of the fixing post 3 on the first aid station 1 is adjustable.

[0045] The first aid station 1 is provided with four fixed post mounting slots 2. The fixed post mounting slots 2 are long slots. There are four fixed posts 3. The four fixed posts 3 correspond one-to-one with the four fixed post mounting slots 2. The fixed position of the fixed posts 3 in the fixed post mounting slots 2 is adjustable to adapt to different kinds of animals and ensure that the animal's limbs can be stably fixed.

[0046] In one embodiment, the lower side of the emergency station 1 is also provided with four support legs 4 for supporting the entire animal heart compression machine.

[0047] The working principle of the animal heart compression device according to this embodiment of the utility model is as follows:

[0048] First, adjust the fixed position of the fixing post 3 in the fixing post mounting groove 2 to accommodate different types of animals and ensure stable fixation of the animal's limbs. Then, depending on the animal species, pull the eccentric wheel 10 away from the drive shaft 11. When pulling the eccentric wheel 10, the slot 23 on the eccentric wheel 10 disengages from the insert 27 on the drive shaft 11. At this point, the eccentric wheel 10 can be moved up and down according to the animal species. When the eccentric wheel 10 is moved to a suitable position, push it towards the power unit 9, causing the insert 27 on the drive shaft 11 to insert into the slot 23 in the elongated insertion hole 22, thus connecting the drive shaft and the eccentric wheel 10. This allows the drive shaft 11 to rotate, driving the eccentric wheel 10 to rotate. Furthermore, during the up-and-down movement of the eccentric wheel 10, the top of the rod 16 remains in contact with the wheel surface of the eccentric wheel 10 under the elastic force of the spring, preventing the rod 16 from disengaging from the eccentric wheel 10.

[0049] After adjusting the position of the pressing head 15 so that it is directly facing the animal's heart, the power unit 9 is activated. The power unit 9 drives the eccentric wheel 10 to rotate. When the wheel surface of the eccentric wheel 10 away from the drive shaft 11 abuts against the rod 16, the wheel surface of the eccentric wheel 10 forces the rod 16 to move downward so that the bottom end of the rod 16 presses against the animal's heart. At this time, the spring is compressed. When the wheel surface of the eccentric wheel 10 close to the drive shaft 11 abuts against the rod 16, under the elastic force of the spring, the stop platform 38 drives the rod 16 to move upward so that the bottom end of the rod 16 moves away from the animal.

[0050] According to the animal heart compression machine of this utility model embodiment, the depth adjustment component can adjust the downward stroke of the compression head 15, thereby adjusting the compression depth of the compression head 15 on the heart of the animal placed on the emergency table 1. It can be adapted to different kinds of animals, improve the applicability of the animal heart compression machine, and improve the treatment effect of the animal by adjusting the compression depth of the compression head 15 according to the type of animal.

[0051] In other embodiments, the power unit 9 can be a joystick to manually drive the drive shaft 11 to rotate.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
