[0026] Example:

[0027] like Figure 1-7 As shown, in this embodiment, the cardiopulmonary resuscitation machine includes: a pressing component 1, a support arm 2 and a base plate 4, one end of the support arm 2 is detachably connected to the base plate 4, and the other end is rotatably connected to the pressing component 1 through a rotating shaft component 3; a space for placing a patient is formed between the pressing component 1, the support arm 2 and the base plate 4.

[0028] Specifically, the pressing assembly 1 includes a pressing head 12 for pressing the patient's chest, and the bottom plate 4 can be used to carry the patient. During treatment, when the patient lies on the bottom plate 4, the pressing assembly 1 is located above the patient and aligned with the patient's chest. After turning on the machine, the pressing head 12 can reciprocate up and down, press the patient's chest down to a depth of about 5 cm and then return to the initial position again, 120 cycles per minute, thereby performing cardiopulmonary resuscitation. The support arm 2 is detachably connected to the bottom plate 4, and the support arm 2 is rotatably connected to the pressing assembly 1. When the cardiopulmonary resuscitation machine is not needed, the support arm 2 and the bottom plate 4 can be disassembled, and then the space occupied by the pressing assembly 1 and the support arm 2 is minimized by rotating the angle between the support arm 2 and the pressing assembly 1, which is convenient for storage and helps to save storage space; and when stored, the pressing assembly 1 and the support arm 2 are still connected as a whole, and there is no need to re-assemble the pressing assembly 1 and the support arm 2 specifically when used again, which further improves the portability and flexibility of the cardiopulmonary resuscitation machine.

[0029] like Figure 2-5 As shown, in this embodiment, the shaft assembly 3 includes a shaft 31, the pressing assembly 1 includes a shell 11 formed with a first mounting cavity 111, and the support arm 2 is provided with a second mounting cavity 21, one end of the shaft 31 is rotatably matched with the first mounting cavity 111, and the other end is fixedly matched with the second mounting cavity 21. That is, one end of the shaft 31 and the first mounting cavity 111 can rotate relative to each other at a certain angle, and the other end of the shaft 31 is fixedly connected to the second mounting cavity 21, thereby realizing the rotational connection between the shell 11 and the support arm 2. It is understandable that in some other embodiments, it can also be arranged in a form in which the shaft 31 can rotate relative to the first mounting cavity 111 and the second mounting cavity 21 respectively; it can also be arranged in a form in which the shaft 31 is fixed to the first mounting cavity 111, and the shaft 31 and the second mounting cavity 21 can rotate relative to each other, and there is no limitation here.

[0030] Further, in this embodiment, a first boss 112 is provided in the first installation cavity 111, and a second boss 311 matching the shape of the first boss 112 is formed at one end of the rotating shaft 31. One end of the rotating shaft 31 enters the first installation cavity 111 and the first boss 112 and the second boss 311 cooperate with each other to limit the rotation angle between the pressing component 1 and the support arm 2. When the first boss 112 and the second boss 311 abut against each other, the first boss 112 and the second boss 311 can no longer continue to rotate around the axis of the rotating shaft 31 along the current rotation direction, that is, the rotation angle between the pressing component 1 and the support arm 2 reaches the minimum value or the maximum value of the preset angle range, thereby realizing the limitation of the rotation angle, and the limitation of the rotation angle can also ensure the stability of pressing to a certain extent.

[0031] In this embodiment, if Figure 2 and6 As shown, the rotating shaft assembly 3 also includes a torsion spring 32, which is sleeved on the outer peripheral side of the rotating shaft 31, and one end of the torsion spring 32 is fixedly connected to the shell 11, and the other end is fixedly connected to the rotating shaft 31; the torsion spring 32 has a force on the support arm 2 to rotate the support arm 2 in a direction away from the clearance space.

[0032] Specifically, the torsion spring 32 includes a first mounting arm and a second mounting arm respectively disposed at both ends, and the housing 11 and the rotating shaft 31 are also respectively provided with a corresponding first mounting hole 113 and a second mounting hole 313, the first mounting arm is fixed in the first mounting hole 113, and the second mounting arm is fixed in the second mounting hole 313. The support arm 2 is fixedly connected to the rotating shaft 31, and the force of the torsion spring 32 can make the support arm 2 always maintain an open angle, which is more conducive to quickly mounting the support arm 2 to the bottom plate 4 and quickly treating the patient.

[0033] In this embodiment, a third boss 312 is formed at one end of the rotating shaft 31 away from the second boss 311, a groove 211 matching the shape of the third boss 312 is formed in the second installation cavity 21, and the third boss 312 abuts against the groove 211. The third boss 312 is embedded in the groove 211, that is, the third boss 312 abuts against the wall of the groove 211, so that the third boss 312 can be firmly fixed to the groove 211, and then the rotating shaft 31 can be fixedly connected to the second installation cavity 21 and the support arm 2.

[0034] In this embodiment, the cardiopulmonary resuscitation machine also has a connecting shaft 5, such as Figure 2 As shown, two rotating shaft assemblies 3 are correspondingly arranged between a single support arm 2 and a pressing assembly 1, and the corresponding two rotating shaft assemblies 3 are respectively sleeved on the two ends of the connecting shaft 5, and the mutual rotation direction between the pressing assembly 1 and the support arm 2 is perpendicular to the length extension direction of the connecting shaft 5. Specifically, an installation cavity is also formed between the two corresponding first installation cavities 111 in the shell 11, and the rotating shaft 31 is passed through the first installation cavity 111 and the corresponding installation cavity. The rotating shaft 31 is also provided with an assembly cavity 314 for fitting and fixing with the connecting shaft 5, that is, the two ends of the rotating shaft 31 pass through the corresponding assembly cavity 314 and fit and fix with the rotating shaft 31. The support arm 2 and the shell 11 of the pressing assembly 1 are connected through the two rotating shaft assemblies 3 and the connecting shaft 5, which is conducive to improving the structural stability of the connection between the support arm 2 and the pressing assembly 1, and thus improving the structural stability of the entire cardiopulmonary resuscitation machine.

[0035] Furthermore, if Figure 2As shown, in this embodiment, the connecting shaft 5 and the corresponding rotating shaft 31 are fixed by a nut 6. That is, the rotating shaft 31 can be locked to the connecting shaft 5 by the nut 6 to prevent the connecting shaft 5 from being displaced and running out, further improving the structural stability of the pressing assembly 1 and the support arm 2. In this embodiment, an end cover 7 is further provided at the end of the second mounting cavity 21 away from the first mounting cavity 111, and the rotating shaft assembly 3 is shielded by the end cover 7, thereby improving the aesthetics of the cardiopulmonary resuscitation machine. It is understandable that in some other embodiments, the second mounting cavity 21 can also be set as a closed mounting cavity, which has a simple structure and can also shield internal structures such as the transfer assembly, which is not limited here.

[0036] like Figure 1 , Figure 2 , Figure 7 As shown, in this embodiment, two support arms 2 are symmetrically arranged, and the two support arms 2 can provide sufficient support force for the pressing assembly 1, and can leave enough space for placing the patient in the clearance space. A fixing portion 41 is arranged on the edge of the bottom plate 4, and a buckle 22 adapted to the fixing portion 41 is arranged at one end of the support arm 2 away from the pressing assembly 1, and the buckle 22 is buckled and fixed with the fixing portion 41. The bottom plate 4 and the support arm 2 are fixed by buckling, which can ensure the stability of the structural connection, and the support arm 2 and the bottom plate 4 are easy to disassemble and assemble, and the use, assembly, storage and transportation of the cardiopulmonary resuscitation machine are more flexible, thereby improving the convenience of the cardiopulmonary resuscitation machine.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
