Description

Technical Field

[0001] The present invention specifically relates to an external chest compression device. Background Art

[0002] External chest compression is an important means in the first aid process, which mainly includes two actions: external chest compression and artificial respiration. Usually, the ventilation volume is combined with 30 external chest compressions and 2 artificial respirations. Among them, for adults, each external chest compression requires a compression stroke of at least 5 cm (at least 5 cm for infants and at least 4 cm for children), and the compression frequency is not less than 100 times per minute. Currently, first aid work is usually carried out manually, and continuous external chest compression is required. Since manual operation is very likely to cause fatigue of the rescuer, usually two rescuers take turns, but there will inevitably be pauses.

[0003] In addition, some existing external chest compression assistance devices can only perform external chest compression during first aid and cannot perform artificial respiration. Therefore, after every 30 external chest compressions, another device or manual method must be used to assist breathing, which not only prolongs the rescue time but also brings trouble to the rescue. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide an external chest compression device, which can not only solve the problem of fatigue of the rescuer caused by manual external chest compression, but also perform two actions of artificial respiration while performing external chest compression, greatly simplifying the rescue operation.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: An external chest compression device, comprising:

[0006] A bottom plate;

[0007] A mounting rack, arranged on the bottom plate;

[0008] A pressing member, movably mounted on the mounting rack in the up and down direction;

[0009] A pressing drive source, connected to the pressing member, capable of regularly driving the pressing member to reciprocate up and down 50 times within every 30 seconds, and pausing once after every 30 reciprocating movements up and down;

[0010] An air nozzle, which can be held in the mouth, and a trachea is connected to the air nozzle;

[0011] An inflation structure, communicated with the trachea, capable of continuously introducing air into the air nozzle twice during each pause of the pressing member.

[0012] Further, the pressing member includes a guiding block, a pushing plate, a push rod, and a pressing head. The guiding block is fixed on the mounting bracket. A guiding hole perpendicular to the bottom plate is formed on the guiding block. The push rod is inserted into the guiding hole and can move up and down. The pushing plate is arranged at the top end of the push rod, and the pressing head is arranged at the bottom end of the push rod. The pressing driving source is connected to the pushing plate and can drive the pushing plate to reciprocate up and down regularly 50 times within every 30 seconds and pause once after every 30 reciprocating movements.

[0013] Further, the pressing driving source includes a rotary power source, a first rotary disk, a first pushing block, and a first elastic member. The first elastic member is supported between the guiding block and the pushing plate. The first rotary disk is rotatably mounted on the mounting bracket. The rotary power source is connected to the first rotary disk and is used to drive the first rotary disk to rotate one week every 20 seconds. There are 30 first pushing blocks. 32 first mounting positions are circumferentially and evenly arranged on the side wall of the first rotary disk. The 30 first pushing blocks are sequentially arranged on 30 of the first mounting positions. When the rotary power source drives the first rotary disk to rotate, the 30 first pushing blocks can sequentially contact the pushing plate to push the pushing plate to move downward by at least 3 cm.

[0014] Further, the outer surface of the first pushing block is arc-shaped, and the pushing plate is slidably connected to the first pushing block.

[0015] Further, a jack is radially formed at each of the first mounting positions. The first pushing block includes a mounting rod and an arc-shaped plate. The mounting rod can move radially in the jack, and the arc-shaped plate is fixed at the end of the mounting rod. The concave surface of the arc-shaped plate faces the first rotary disk.

[0016] Further, the pressing driving source further includes a pushing distance adjusting structure, which is connected to the first pushing block and is used to adjust the distance between the ends of all the first pushing blocks and the center of the first rotary disk.

[0017] Further, the pushing distance adjusting structure includes a center rod, a connecting rod, and an adjusting block. The center rod is vertically fixed at the center of the first rotary disk. The adjusting block is threadedly connected to the center rod. A connecting rod is hinged to each mounting rod, and the other ends of all the connecting rods are hinged to the corresponding adjusting blocks.

[0018] Further, the inflation structure includes a second rotating disk, a second pushing block, and an inflation ball. The second rotating disk is coaxially arranged with the first rotating disk. Thirty-two second installation positions are circumferentially and evenly arranged on the side wall of the second rotating disk. The second installation positions are aligned with the first installation positions. The second pushing block is arranged on two adjacent second installation positions and is located between the gaps formed by 30 successively arranged first pushing blocks.

[0019] The inflation ball is arranged below the second pushing block. One end of the inflation ball is provided with an intake one-way valve. The inflation ball is communicated with the trachea. When the second rotating disk rotates, the two second pushing blocks can successively press on the inflation ball.

[0020] Further, a second elastic member is arranged inside the inflation ball. The second elastic member vertically supports inside the inflation ball.

[0021] Further, the air nozzle is arranged on a fixing strap that can be fixed to the head.

[0022] Advantages of the present invention:

[0023] When the above-mentioned external chest compression device is used for rescue, first place the patient on the bottom plate so that the chest cavity is directly below the pressing member. Then start the pressing drive source and the inflation structure. The pressing drive source drives the pressing member to move downward for external chest compression. During the pause period when the pressing drive source drives the pressing member to press 30 times, the inflation structure intakes air into the air nozzle continuously twice, so that the two actions of external chest compression and artificial respiration can be realized.

[0024] By using such a device, the problem that the rescuer is fatigued due to manual external chest compression can be solved. In addition, the two actions of external chest compression and artificial respiration can be carried out simultaneously, greatly simplifying the rescue operation actions. Description of the drawings

Specific embodiments

[0033] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Please refer to Figures 1 to 5 , the present invention provides an external chest compression device, including a bottom plate 100, a mounting bracket 200, a pressing member 300, a pressing drive source 400, an air nozzle 500 and an inflation structure 600.

[0035] Specifically, the mounting bracket 200 is arranged on the bottom plate 100; the pressing member 300 is movably mounted on the mounting bracket 200 in the up and down direction. The pressing drive source 400 is connected to the pressing member 300 and can regularly drive the pressing member 300 to reciprocate up and down 50 times within every 30 seconds and pause once after every 30 reciprocating motions up and down. The air nozzle 500 can be held in the mouth, and a trachea is connected to the air nozzle 500. In specific implementation, a fixing strap that can be fixed to the head can be arranged on the air nozzle 500. The inflation structure 600 is communicated with the trachea, and air can be continuously introduced into the air nozzle 500 twice during each pause of the pressing member 300.

[0036] When performing first aid, first place the patient on the bottom plate 100 so that the chest cavity is directly below the pressing member 300. Then start the pressing drive source 400 and the inflation structure 600. The pressing drive source 400 drives the pressing member 300 to move downward for external chest compressions. During the pause period when the pressing drive source 400 drives the pressing member 300 to press 30 times each time, the inflation structure 600 continuously intakes air into the air nozzle 500 twice, then the two actions of external chest compressions and artificial respiration can be achieved.

[0037] Using such a device can not only solve the problem of fatigue of the rescuer caused by manual external chest compressions, but also, while performing external chest compressions, the two actions of artificial respiration can be carried out, greatly simplifying the first aid operation actions.

[0038] In this embodiment, the pressing member 300 includes a guide block 310, a push plate 320, a push rod 330 and a pressing head 340. The guide block 310 is fixed on the mounting frame 200, and a guide hole perpendicular to the bottom plate 100 is provided on the guide block 310. The push rod 330 is inserted into the guide hole and can move up and down. The push plate 320 is arranged at the top end of the push rod 330, and the pressing head 340 is arranged at the bottom end of the push rod 330. The pressing drive source 400 is connected to the push plate 320 and can drive the push plate 320 to reciprocate up and down regularly 50 times within every 30 seconds and pause once after every 30 reciprocating motions.

[0039] It should be noted that in specific implementation, the push rod 330 can be set to be adjustable in length. Before the patient is placed on the bottom plate, the push rod 330 is adjusted to be short. After the patient's body position is placed, the length of the push rod is adjusted so that the pressing head closely adheres to the surface of the chest cavity.

[0040] In specific implementation, the rotary power source 410 can be selected from a rotary motor, or a mechanism such as a gear and rack that can drive the first rotary disk 420 to rotate regularly together.

[0041] When in use, as the first rotary disk 420 rotates, 30 first pushing blocks 430 sequentially contact the push plate 320 and push the push plate 320 downward. When the first pushing block 430 disengages from the push plate 320, under the action of the first elastic member 440, the push plate 320 is driven to rise, thereby driving the pressing head 340 to return to its position to prepare for the second compression.

[0042] In specific implementation, the outer surface of the first pushing block 430 can be arc-shaped, so as to facilitate the sliding connection between the push plate 320 and the first pushing block 430 and further smoothly push the push plate 320.

[0043] In this embodiment, jacks are radially formed at each first installation position. The first push block 430 includes an installation rod 431 and an arc plate 432. The installation rod 431 is capable of radial movement within the jack, and the arc plate 432 is fixed to the end of the installation rod 431. The concave surface of the arc plate 432 faces the first rotating disk 420.

[0044] As a preferred embodiment, the device further includes a pushing distance adjustment structure 450. The pushing distance adjustment structure 450 is connected to the first push block 430 and is used to adjust the distance between the ends of all the first push blocks 430 and the center of the first rotating disk 420.

[0045] Specifically, the pushing distance adjustment structure 450 includes a central rod 451, a connecting rod 452, and an adjustment block 453. The central rod 451 is vertically fixed to the center of the first rotating disk 420, and the adjustment block 453 is threadedly connected to the central rod 451. A connecting rod 452 is hinged to each installation rod 431, and the other ends of all the connecting rods 452 are hinged to the corresponding adjustment block 453.

[0046] When it is necessary to increase the distance between the end of the first push block 430 and the center of the first rotating disk 420, only need to rotate the adjustment block 453 to move the adjustment block 453 in the direction close to the first rotating disk 420, and the installation rod 431 can be pushed outward through the 30 connecting rods 452; on the contrary, when it is necessary to decrease the distance between the end of the first push block 430 and the center of the first rotating disk 420, only need to rotate the adjustment block 453 in the reverse direction.

[0047] In this way, the distances of the ends of the 30 first push blocks 430 can be adjusted simultaneously and synchronously. Of course, in other embodiments, other adjustment methods can be adopted, such as sequentially adjusting the extended distance of each installation rod 431, or selecting other driving methods.

[0048] By adjusting the distance between the end of the first push block 430 and the center of the first rotating disk 420, the distance of squeezing the chest cavity can be adjusted. For example: for infants, the squeezing distance can be adjusted to at least 3 cm; for children, the squeezing distance can be adjusted to at least 4 cm; for adults, the squeezing distance can be adjusted to at least 5 cm.

[0049] In this embodiment, the inflation structure 600 includes a second rotating disk 610, a second push block 620, and an inflation ball 630. The second rotating disk 610 is coaxially arranged with the first rotating disk 420. Thirty-two second installation positions are circumferentially and evenly arranged on the side wall of the second rotating disk 610, and the second installation positions are aligned with the first installation positions. The second push block 620 is arranged at two adjacent second installation positions and is located between the gaps formed by the 30 sequentially arranged first push blocks 430;

[0050] The inflatable balloon 630 is arranged below the second pushing block 620. One end of the inflatable balloon 630 is provided with an intake one-way valve. The inflatable balloon 630 is communicated with the trachea. When the second rotating disc 610 rotates, the two second pushing blocks 620 can sequentially press on the inflatable balloon 630. It should be noted that in this embodiment, the structures of the inflatable balloon 630 and the intake one-way valve are similar to those of the inflatable balloon 630 and the intake one-way valve used in a sphygmomanometer. When the inflatable balloon 630 is squeezed, the intake one-way valve closes, and the gas is discharged from the trachea. When the pressure is released, the gas enters from the intake one-way valve, and the shape of the inflatable balloon 630 is restored.

[0051] When the rotary power source 410 is started, when driving the first rotating disc 420 to rotate, the second rotating disc 610 is synchronously driven to rotate. During the process of the first pushing block 430 contacting the push plate 320, the second pushing block 620 does not contact the inflatable balloon 630. After the 30th first pushing block 430 separates from the push plate 320, as the rotating disc continues to rotate, the two second pushing blocks 620 sequentially squeeze the inflatable balloon 630 to perform two blowing operations to realize two artificial respiration actions. After the two blowing actions are completed, the 1st first pushing block 430 pushes the push plate 320 again.

[0052] As a preferred implementation manner, a second elastic member is arranged inside the inflatable balloon 630, and the second elastic member vertically supports inside the inflatable balloon 630. When the second pushing block 620 separates from the inflatable balloon 630, the second elastic member can assist the inflatable balloon 630 to quickly restore its shape, so that the inside of the inflatable balloon 630 is quickly filled with gas.

[0053] The specific method of using the above-mentioned external chest compression device:

[0054] During use, first adjust the distance between the first pushing block and the central axis according to the patient's condition. When performing rescue, first place the patient on the bottom plate 100 so that the chest cavity is directly below the pressing head 340. Subsequently, start the rotary power source 410 to drive the pressing member, the first rotating disc 420 and the second rotating disc 610, then it is possible to perform two artificial respirations after every 30 external chest compressions.

[0055] By adopting such a device, it can not only solve the problem of fatigue of the rescuer caused by manual external chest compression. In addition, two actions of external chest compression and artificial respiration can be performed simultaneously, greatly simplifying the rescue operation actions. At the same time, it can be adapted for the use of infants, children and adults.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
