The present invention is provided with a central frame, a cover body, a connecting strap, a first locking mechanism, a supporting mechanism, a cardiopulmonary resuscitation device body and an auxiliary supporting structure. The first locking mechanism fixes the two cover bodies to keep the two cover bodies in line. The supporting mechanism fixes the central frame to ensure that the line connecting the central frame and the two cover bodies remains vertical, thereby enhancing the stability of the device. The cardiopulmonary resuscitation device body is aligned with the pressing position, and a force is applied to the cardiopulmonary resuscitation device body toward the patient, so that the cardiopulmonary resuscitation device body can immediately participate in cardiopulmonary resuscitation. The connecting strap can tightly fix the two cover bodies on the patient's chest to ensure that the device will not fall off or shift due to the movement of the patient during operation.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Reference Figures 1 to 14As shown: A cardiopulmonary resuscitation device, including a folding storage mechanism 1, a cardiopulmonary resuscitation device body 2, a power supply structure 3 and an auxiliary support structure 4; the folding storage mechanism 1 includes a central frame 11, two cover bodies 12, a connecting strap 13, a first locking mechanism 14 and two supporting mechanisms 15, the interior of the central frame 11 is hollow, the two cover bodies 12 are respectively arranged on both sides of the central frame 11, and one end of the cover body 12 is axially connected to the central frame 11, and the other end of the cover body 12 is provided with a handle 121, the two ends of the connecting strap 13 are respectively connected to the two ends of the two cover bodies 12, and the first locking mechanism 14 is arranged between the two ends of the two cover bodies 12 and the central frame 11. , two supporting mechanisms 15 are respectively arranged on both sides of the central frame 11, and the two ends of the supporting mechanisms 15 are respectively connected to the central frame and the cover body 12; the cardiopulmonary resuscitation device body 2 is arranged in the central frame 11, and the cardiopulmonary resuscitation device body 2 includes a pressing rod 21 and a pressing head 22, one end of the pressing rod 21 extends from one end of the central frame 11, and the end is axially connected to the two cover bodies 12, and the pressing head 22 is connected to one end of the pressing rod 21; the power supply structure 3 is arranged in the central frame 11, and the power supply structure 3 is electrically connected to the cardiopulmonary resuscitation device body 2; the auxiliary supporting structure 4 has two, and the two auxiliary supporting structures 4 are respectively arranged on two opposite sides of the two cover bodies 12.

[0041] In the initial state, the two covers 12 completely wrap the central frame 11, so that the entire device is folded and contracted into a regular and smaller shape. When using the device, the medical staff first rotates the two covers 12 to be parallel. At this time, the line connecting the two covers 12 is perpendicular to the central frame 11. Then, the first locking mechanism 14 fixes the two covers 12 to keep them in line to provide support for the cardiopulmonary resuscitation device body 2. Then, the two supporting mechanisms 15 fix the central frame 11 to ensure that the line connecting the central frame 11 and the two covers 12 remains perpendicular. First, one end of the connecting strap 13 is passed through the patient's back, and then the cardiopulmonary resuscitation device body 2 is aligned with the pressing position, and the cardiopulmonary resuscitation device body 2 is applied in the direction of The patient's force causes the power supply structure 3 to supply power to the cardiopulmonary resuscitation device body 2, and the cardiopulmonary resuscitation device body 2 immediately participates in cardiopulmonary resuscitation. The other medical staff then connect the two ends of the connecting strap 13 to the two covers 12, and tighten the connecting strap 13 to press the two covers 12 against the patient's chest. Since the patient's chest is not flat, the cover 12 may shake when the cardiopulmonary resuscitation device body 2 is working. Therefore, it is necessary to adjust the auxiliary support structure 4 to support the gap between the cover 12 and the patient's chest to keep the cardiopulmonary resuscitation device body 2 stable when working, so as to achieve rescue of the patient before the folded cardiopulmonary resuscitation device is fully unfolded, thereby reducing the preparation time before rescue.

[0042] Reference Figure 4 , Figure 5 and Figure 6As shown in the figure, the supporting mechanism 15 includes a connecting arm 151, a connecting block 152, a first guiding structure 153 and a driving structure 154; one end of the connecting arm 151 is hinged to the end of the central frame 11 away from the end thereof axially connected to the two cover bodies 12; the connecting block 152 is arranged in the cover body 12, and the middle part of the connecting block 152 is connected to the other end of the connecting arm 151; the first guiding structure 153 is arranged on one side of the connecting block 152, and the first guiding structure 153 is connected to one end of the connecting block 152, and the first guiding structure 153 includes a first guiding cross bar 1531, a first sliding block 1532 and a third spring 1533, and the first guiding Both ends of the cross bar 1531 are connected to the cover body 12, the first slider 1532 is slidably set on the first guide cross bar 1531, and the first slider 1532 is connected to the connecting block 152; the driving structure 154 is set on the other side of the connecting block 152, the driving structure 154 is connected to the other end of the connecting block 152, the driving structure 154 includes a screw rod 1541 and a moving block 1542, the screw rod 1541 is arranged parallel to the first guide cross bar 1531, one end of the screw rod 1541 extends out of the first cover body 12, the moving block 1542 is transmission-connected to the screw rod 1541, and the moving block 1542 is connected to the connecting block 152.

[0043] After the two cover bodies 12 are connected by the first locking mechanism 14, the medical staff rotates the screw rod 1541 of the supporting mechanism 15 to make adjustments. The screw rod 1541 drives the moving block 1542 to move along its axis, and the moving block 1542 moves to a predetermined position along the screw rod 1541. The driving force generated by the moving block 1542 is effectively transmitted to the connecting block 152 connected thereto. After receiving the driving force, the connecting block 152 pulls the first slider 1532 fixedly connected thereto to slide on the first guide cross bar 1531. During the sliding process, the first slider 1532 compresses the third spring 1533 to store elastic potential energy. With the continuous movement of the connecting block 152, the angle between the connecting arm 151 and the central frame 11 gradually increases. When the two supporting mechanisms 15 are adjusted to the predetermined positions, two stable triangular structures are formed on both sides of the central frame 11, which realizes a uniform distribution of tension, thereby enhancing the stability of the central frame 11 during operation and providing a stable support foundation for cardiopulmonary resuscitation operations.

[0044] Reference Figure 6 and Figure 7As shown: the connecting arm 151 includes a first connecting rod 1511, a second connecting rod 1512 and a second spring 1513; one end of the first connecting rod 1511 is hinged to the central frame 11; the second connecting rod 1512 is coaxially arranged with the first connecting rod 1511, the second connecting rod 1512 and the first connecting rod 1511 are slidably connected to each other, and one end of the second connecting rod 1512 is axially connected to the middle part of the connecting block 152; the second spring 1513 is sleeved on the first connecting rod 1511 and the second connecting rod 1512, and the two ends of the second spring 1513 are respectively connected to the end of the first connecting rod 1511 and the end of the second connecting rod 1512.

[0045] If the length of the connecting arm 151 is fixed, the driving structure 154 cannot drive the connecting block 152 to move, and the connecting arm 151 cannot effectively apply a pulling force to the central frame 11. The connecting arm 151 is configured to be a first connecting rod 1511, a second connecting rod 1512, and a second spring 1513. In the initial state, the second spring 1513 is in a contracted state. The second spring 1513 applies a pulling force to the first connecting rod 1511 and the second connecting rod 1512 to keep them close to each other. When the driving structure 154 starts to drive the connecting block 152, the connecting block 152 is moved. When the movable connecting block 152 moves, since the second connecting rod 1512 is connected to the connecting block 152, the movement of the connecting block 152 will drive the second connecting rod 1512 to move. During this process, relative sliding will occur between the second connecting rod 1512 and the first connecting rod 1511. At the same time, the second spring 1513 is gradually stretched to store elastic potential energy. The stretching of the second spring 1513 gradually increases the pulling force on the first connecting rod 1511, and the pulling force is applied to the central frame 11, so that the connecting arm 151 can adapt to different working conditions of folding and contraction and applying pulling force to the central frame 11.

[0046] Reference Figure 5 and Figure 8As shown: the first locking mechanism 14 includes a locking connecting plate 141 and a first fixing structure 142; the locking connecting plate 141 is arranged on the side wall of one of the cover bodies 12, and the two ends of the locking connecting plate 141 are respectively a first rotating part and a fixing part, and the first rotating part is axially connected to the cover body 12; the first fixing structure 142 is arranged on the side wall of the other cover body 12, and the first fixing structure 142 includes a storage box 1421, a fixing rod 1422, a push rod 1423 and a first spring 1424, and the storage box 142 1 is fixed on the side wall of the cover body 12, a first sliding groove is opened on the side of the storage box 1421, a fixed rod 1422 is slidably arranged in the storage box 1421, and one end of the fixed rod 1422 extends out of the storage box 1421, one end of the push rod 1423 passes through the first sliding groove and is connected with the other end of the fixed rod 1422, a first spring 1424 is arranged inside the storage box 1421, and two ends of the first spring 1424 are respectively abutted against the end of the fixed rod 1422 and the end of the storage box 1421.

[0047] After the two cover bodies 12 are rotated to the colinear position, a locking operation is performed to ensure that the two cover bodies 12 form a stable whole. The medical staff first applies a driving force to the fixed portion of the locking connecting plate 141 to rotate the locking connecting plate 141 around its first rotating portion to rotate the fixed portion to the corresponding position of the other cover body 12. At this time, the two ends of the locking connecting plate 141 are respectively located inside the two cover bodies 12, crossing the dividing line of the two cover bodies 12, achieving preliminary fixation and preventing the relative rotation between the cover bodies 12. In order to ensure the stability of the locking connection and prevent the vibration generated during the operation of the cardiopulmonary resuscitation device body 2 from affecting the stability of the locking connecting plate 141, the locking connection needs to be further The plate 141 is locked, and the medical staff applies an inward thrust to the push rod 1423, and the thrust is transmitted to the fixed plug rod 1422 through the push rod 1423, so that the fixed plug rod 1422 slides in the storage box 1421 and moves inward, and the first spring 1424 is compressed and stores elastic potential energy. When the fixed part rotates to a position corresponding to the fixed plug rod 1422, the medical staff stops applying thrust to the push rod 1423, and the first spring 1424 releases energy, pushing the fixed plug rod 1422 to move outward until it is inserted into the interior of the fixed part of the locking connecting plate 141, thereby achieving the final locking of the locking connecting plate 141, thereby achieving a quick, simple and firm locking between the two cover bodies 12.

[0048] Reference Fig. 9 As shown, the first locking mechanism 14 further includes a second fixing structure 143 , which is disposed on the cover body 12 on which the locking connecting plate 141 is installed, and the second fixing structure 143 has the same structure as the first fixing structure 142 .

[0049] When the device is folded and stored, if the locking connecting plate 141 is not fixed, the locking connecting plate 141 may swing freely around its first rotating part. Therefore, a second fixing structure 143 is set on the cover body 12 on which the locking connecting plate 141 is installed. The second fixing structure 143 has the same structure and working principle as the first fixing structure 142. Specifically, the storage box 1421, the fixed plug 1422, the push rod 1423 and the first spring 1424 in the second fixing structure 143 work together to effectively fix the locking connecting plate 141, prevent the locking connecting plate 141 from swinging around its first rotating part unexpectedly, thereby ensuring the stability and safety of the device in the folded storage state.

[0050] Reference Figure 4 and Fig.10 As shown: the folding storage mechanism 1 also includes two second locking mechanisms 16, which are respectively arranged at the ends of the two cover bodies 12, and the second locking mechanisms 16 are respectively connected to the two cover bodies 12. The second locking mechanism 16 includes a connecting seat 161, a rotating rod 162, an elastic telescopic arm 164 and a locking rod 163. The two ends of the connecting seat 161 are respectively the second rotating part and the locking part, one end of the rotating rod 162 is arranged in the rotating part, and the locking rod 163 is arranged parallel to one side of the rotating rod 162, and the two ends of the elastic telescopic arm 164 are respectively connected to the locking rod 163 and the rotating rod 162.

[0051] After the two covers 12 are rotated to the two sides of the central frame 11, if the two covers 12 and the central frame 11 are not fixed by locking, the two covers 12 may be unexpectedly separated from the central frame 11 due to vibration during the movement of the carrying device. Therefore, a second locking mechanism 16 is provided at the ends of the two covers 12. When the two covers 12 are in contact with the central frame 11, the medical staff applies a pulling force to the locking rod 163 to cause the elastic telescopic arm 164 to elastically deform, thereby increasing the distance between the locking rod 163 and the rotating rod 162 until the distance between the locking rod 163 and the rotating rod 162 exceeds the distance between the two covers 1 2, then, the rotating rod 162 rotates around the second rotating part of the connecting seat 161, driving the locking rod 163 to move to the side of the other cover body 12, at this time, the locking rod 163 is embedded in the locking part of the connecting seat 161 to realize the locking function and prevent the locking rod 163 from being displaced during the movement, then, the elastic telescopic arm 164 returns to its original state and generates a force toward the middle of the central frame 11, and the generated force is used to rotate the rod 162 and the locking rod 163, so that the two cover bodies 12 are closely fitted with the central frame 11, thereby effectively preventing the cover body 12 from being separated from the central frame 11 due to vibration during the movement.

[0052] Reference Figure 1 , Fig.11 and Fig.12 As shown in the figure: the power supply structure 3 includes a battery installation compartment 31 and four quick locking structures 32; the battery installation compartment 31 is fixedly arranged on the inner wall surface of the central frame 11; the four quick locking structures 32 are respectively arranged on the four corners of the battery installation compartment 31, and the quick locking structure 32 includes a locking block 321 and an elastic telescopic structure 322, one end of the locking block 321 is V-shaped and extends into the interior of the battery installation compartment 31, and the elastic telescopic structure 322 includes a sleeve 3221, a limit plate 3222, a cover plate 3224 and a first Four springs 3223, one end of the sleeve 3221 is connected to the battery mounting compartment 31, the other end of the sleeve 3221 is provided with two second sliding grooves extending toward the middle of the sleeve 3221, the limit plate 3222 is connected to the other end of the locking block 321, and the two ends of the limit plate 3222 are located in the two second sliding grooves, the cover plate 3224 is covered on the other end of the sleeve 3221, the fourth spring 3223 is arranged in the sleeve 3221, and the two ends of the fourth spring 3223 are respectively abutted against the locking block 321 and the cover plate 3224.

[0053] During the process of first aid for the patient provided by the cardiopulmonary resuscitation device body 2, if the power supply battery fails to provide power, disassembling the device will cause interruption or delay of first aid, so it is necessary to quickly replace the spare battery. The medical staff places the spare battery at the entrance of the battery installation compartment 31, and then pushes the spare battery forward for installation by applying a force toward the inside of the battery installation compartment 31. During this process, the spare battery first contacts the locking block 321 located on its travel path. One end of the locking block 321 is V-shaped and extends into the battery installation compartment 31 for locking and unlocking the battery. When the spare battery contacts the locking block 321, the locking block 321 and the limit plate 3222 connected thereto are locked on the fourth spring Under the action of 3223, it moves into the sleeve 3221, and the fourth spring 3223 is compressed. As the spare battery continues to be pushed forward, the battery in use is pushed out of the battery installation compartment 31. At the same time, the locking block 321 in front of the battery in use also moves into the sleeve 3221. When the spare battery completely enters the battery installation compartment 31, its force on the locking block 321 disappears, and the fourth spring 3223 releases the previously compressed elastic potential energy, pushing the locking block 321 and the limit plate 3222 connected to it to move outward until the V-shaped end of the locking block 321 extends into the battery installation compartment 31 again, completing the fixation of the spare battery, thereby realizing the rapid replacement of the power supply battery and effectively reducing the impact on the patient's first aid.

[0054] Reference Figure 2 , Fig.13 and Fig.14As shown: the auxiliary support structure 4 includes a second guide structure 41 and a sponge pad 42; the second guide structure 41 includes a fixed block 411, a second guide cross bar 412, a second slider 413 and an adjusting bolt 414, the fixed block 411 is connected to the cover body 12, the second guide cross bar 412 is parallel to the side of the cover body 12, one end of the second guide cross bar 412 is connected to the fixed block 411, the second slider 413 is slidably arranged on the second guide cross bar 412, one end of the adjusting bolt 414 is connected to the fixed block 411, and the other end of the adjusting bolt 414 is threadedly connected to the second slider 413; the sponge pad 42 is arranged on the second slider 413.

[0055] During the use of the cardiopulmonary resuscitation device body 2, the device body is accurately placed in the middle of the patient's chest, and the shields 12 located on both sides of the central frame 11 cover the appropriate positions on both sides of the middle of the patient's chest. Due to the unevenness of the patient's chest, the contact area between the shield 12 and the patient's chest is relatively limited. This limitation may cause the shield 12 and the cardiopulmonary resuscitation device body 2 to shake during the operation of the cardiopulmonary resuscitation device body 2, which may affect the resuscitation effect. In order to solve the above problem, it is necessary to increase the contact area between the shield 12 and the patient's chest. First, the two shields 12 are placed on the patient's chest. The sponge pad 42 is moved toward the center frame 11 by rotating the adjusting bolt 414 and utilizing the threaded connection between the bolt and the second slider 413. At the same time, the second guide cross bar 412 restricts the sliding of the second slider 413 to ensure that the sponge pad 42 can move toward the center frame 11. The sponge pad 42 can fit the patient's chest shape closely by virtue of its elastic properties, effectively filling the gap between the mask body 12 and the patient's chest, thereby significantly increasing the contact area between the mask body 12 and the patient's chest, effectively reducing the shaking of the cardiopulmonary resuscitation device body 2 during operation, and improving the stability of the resuscitation operation.

[0056] Reference Fig.13 and Fig.14 As shown: the auxiliary support structure 4 also includes a support assembly 43, which is arranged on the second slider 413, and the support assembly 43 includes a rectangular frame 431 and a roller 432, the rectangular frame 431 is connected to the second slider 413, the roller 432 is arranged in the rectangular frame 431, and the roller 432 is tangent to the cover body 12.

[0057] When the sponge pad 42 is filled between the mask body 12 and the patient's chest, the sponge pad 42 will be subjected to pressure from the patient's chest, and the pressure is perpendicular to the mask body 12. If this pressure causes the second slider 413 to directly contact the mask body 12, the movement resistance of the second slider 413 will be significantly increased. On the contrary, if there is a gap between the second slider 413 and the mask body 12, the pressure may cause the second slider 413 to apply pressure to one end of the second guide cross bar 412, thereby causing the second guide cross bar 412 to bend. In order to solve the above problem, a support assembly 43 is provided on the second slider 413, and the roller 432 is in contact with the mask body 12. During the movement, rolling friction is formed between the roller 432 and the mask body 12, thereby effectively reducing the resistance to the movement of the second slider 413. At the same time, the presence of the roller 432 helps to maintain a constant distance between the second slider 413 and the mask body 12, thereby effectively preventing the bending of the second guide cross bar 412 due to uneven force.

[0058] A method of use based on portable first aid, applied to a cardiopulmonary resuscitation device, comprises the following steps;

[0059] S1, when using the device, remove the locking restrictions of the two second locking mechanisms 16 on the two covers 12, and rotate the two covers 12 to be parallel. At this time, the connecting line of the two covers 12 is perpendicular to the central frame 11;

[0060] S2, the first locking mechanism 14 fixes the two covers 12 to keep the two covers 12 collinear;

[0061] S3, two supporting mechanisms 15 fix the central frame 11 to keep the central frame 11 and the two covers 12 vertical at the same time;

[0062] S4, first pass one end of the connecting strap 13 through the patient's back, then align the cardiopulmonary resuscitation device body 2 with the pressing position, and apply a force toward the patient to the cardiopulmonary resuscitation device body 2, the power supply structure 3 provides power so that the cardiopulmonary resuscitation device body 2 immediately participates in cardiopulmonary resuscitation, and the other medical staff then connect the two ends of the connecting strap 13 to the two covers 12, and tighten the connecting strap 13;

[0063] S5, adjusting the auxiliary support structure 4 so that the user's chest supports the two mask bodies 12.
