Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a cardiopulmonary resuscitation (CPR) compression device and a CPR machine. Background Technology

[0002] Chest compressions are a crucial part of CPR (cardiopulmonary resuscitation). The compression module is the core component of the CPR machine, responsible for performing physical compressions on the patient's chest. Current CPR compression devices with flat compression heads have the following technical drawbacks when in contact with the chest cavity: The CPR machine relies on the bottom of the casing to compress the patient's chest, and the main unit generates heat during operation. If the main unit casing directly contacts the patient, it may cause discomfort. Utility Model Content

[0003] Therefore, it is necessary to provide a cardiopulmonary resuscitation (CPR) compression device and a CPR machine to address the problems existing in current CPR compression devices.

[0004] A cardiopulmonary resuscitation (CPR) compression device includes a main unit, a main unit housing, a connecting frame, and a compression component. The main unit is disposed inside the main unit housing, the main unit housing is fixedly connected to the connecting frame, the compression component is fixedly connected to the connecting frame, and the compression component is spaced at a predetermined distance from the bottom surface of the main unit housing.

[0005] In one embodiment, the rigidity of the connecting frame is greater than the rigidity of the main unit housing.

[0006] In one embodiment, the connecting frame is made of a metallic material.

[0007] In one embodiment, the main unit housing is made of a polymer material.

[0008] In one embodiment, the pressing component includes connecting portions at both ends and pressing portions. The connecting portions extend with a preset radius of curvature to form a structure with a preset arched feature. The pressing portions are fixedly connected to the connecting frame through the connecting portions on both sides.

[0009] In one embodiment, the width of the pressing portion is greater than the width of the connecting portion.

[0010] In one embodiment, the pressing components are symmetrically distributed along the longitudinal central axis.

[0011] In one embodiment, the pressing part is a planar structure, and the pressing part is parallel to the bottom surface of the main housing.

[0012] In one embodiment, the pressing component is made of a polymer material.

[0013] A cardiopulmonary resuscitation (CPR) machine includes a CPR compression device as described in any of the above embodiments.

[0014] The aforementioned cardiopulmonary resuscitation (CPR) compression device includes a main unit, a main unit housing, a connecting frame, and a compression assembly. The main unit is housed inside the main unit housing, which is fixedly connected to the connecting frame. The compression assembly is also fixedly connected to the connecting frame, with a predetermined distance between the compression assembly and the bottom surface of the main unit housing. During operation, the compression assembly contacts the patient's chest cavity to perform chest compressions. The predetermined distance between the compression assembly and the bottom surface of the main unit housing creates an air barrier between the compression assembly and the heat source within the main unit housing. This prevents the heat generated by the main unit during operation from directly contacting the patient, reducing heat conduction and avoiding discomfort for the patient. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In existing cardiopulmonary resuscitation (CPR) compression devices, the flat compression head has the following technical drawbacks when it comes into contact with the human chest cavity: the main unit generates heat when it is working, and if the main unit casing comes into direct contact with the patient, it may cause discomfort to the patient.

[0022] Figure 1 This is a schematic diagram of the structure of a cardiopulmonary resuscitation (CPR) compression device according to one embodiment of this application. The CPR compression device may include a main unit (not shown), a main unit housing 100, a connecting frame 200, and compression components 300. The main unit is disposed inside the main unit housing 100 and is responsible for controlling the operation of the entire CPR compression device. The main unit may include an electronic control system, a power source, and other necessary hardware components.

[0023] The main housing 100 provides structural support for the main unit and protects it from external environmental influences. The main housing 100 is fixedly connected to the connecting frame 200, forming a stable overall structure. The connecting frame 200, as an intermediate connecting component, not only reinforces and stabilizes the entire device but also provides a fixed foundation for the compression assembly 300. The compression assembly 300 is fixedly connected to the connecting frame 200, with a predetermined distance between the compression assembly 300 and the bottom surface of the main housing 100. When performing CPR compressions on a patient using the cardiopulmonary resuscitation (CPR) compression device, the compression assembly 300 directly applies pressure to the patient's chest. In the CPR compression device provided in this application, the compression assembly 300 is fixed via the connecting frame 200, rather than being directly mounted on the main housing. This reduces the strength requirements on the main housing 100 and improves the overall structural stability.

[0024] By isolating the compression assembly 300 from the bottom surface of the main unit housing 100, an air barrier is created between the compression assembly 300 and the heat source of the main unit. Simultaneously, the preset distance between the compression assembly 300 and the bottom surface of the main unit housing 100 isolates the chest cavity from the compression unit. During operation, the compression assembly 300 contacts the patient's chest cavity to perform chest compressions. The preset distance between the compression assembly 300 and the bottom surface of the main unit housing 100 also creates an air barrier between the compression assembly 300 and the heat source within the main unit housing 100, preventing the heat generated by the main unit from directly affecting the patient, reducing heat conduction and minimizing patient discomfort. Furthermore, a heat dissipation space is formed between the compression assembly 300 and the main unit housing 100, allowing for heat dissipation from the main unit.

[0025] In existing chest compression machine designs, the compression head is typically formed directly into or fixed to the bottom of the main housing 100. This means that the chest compression machine relies primarily on the bottom of the housing to apply force during compressions. However, since the housing may be made of materials such as plastic, its lifespan may be shortened due to stress, thus potentially placing higher demands on the materials used in the housing's fabrication.

[0026] In one embodiment, the connecting frame 200 has a higher hardness than the main housing 100. Since the connecting frame 200 is used for the support and fixation of the entire device, designing it with higher hardness better resists deformation and fatigue damage, maintaining structural integrity and functionality better over long-term use. The high-hardness connecting frame 200 helps prevent operational failures due to frame bending or breakage, thereby increasing the device's safety factor and reducing the risk of accidents. Simultaneously, since the pressing component 300 is fixedly connected to the connecting frame 200 in the cardiopulmonary resuscitation (CPR) compression device provided in this application, and is not directly connected to the main housing 100, the stress on the main housing 100 can be reduced, thus lowering the strength requirements of the device on the main housing 100. By rationally allocating the hardness levels of different components, each part can be kept in optimal working condition, avoiding excessive wear and tear, thereby extending the overall service life of the device.

[0027] In one embodiment, the connecting frame 200 is made of a metallic material. Using a metallic material to manufacture the connecting frame 200 ensures that it has sufficient strength and reliability. The connecting frame 200 is made of metal (such as aluminum alloy, stainless steel, etc.) or other high-strength alloy materials, which have better compressive and bending resistance, effectively supporting and transmitting pressure.

[0028] In one embodiment, the main unit housing 100 is made of a polymer material. In some specific embodiments, the polymer material may include plastic. The main unit housing 100 primarily serves to house and protect the internal main unit. Since the pressing component 300 is not directly connected to the main unit housing 100, its main function is to provide protection and it does not need to withstand significant mechanical stress. The main unit housing 100 can be made of lightweight and cost-effective materials such as plastic, which can meet the protection requirements for the internal main unit while reducing the overall weight of the device.

[0029] In one embodiment, the compression assembly 300 can also be made of a polymer material. In a specific embodiment, engineering plastics with high hardness, high strength, and good abrasion resistance can be selected to fabricate the compression assembly 300; these materials can provide sufficient strength while maintaining a relatively light weight. Furthermore, to increase friction and protect the contact surface from damage, a covering or coating made of rubber, silicone, or other soft materials can be added to the contact surface between the compression assembly 300 and the patient. This not only helps improve the safety and effectiveness of the operation but also reduces potential harm to the patient's skin.

[0030] In some other embodiments, when the pressing component 300 needs to withstand greater pressure or stress according to specific design requirements, intended use, and specific performance requirements, the pressing component 300 may also be made of a high-strength and durable metal material and fixed by the connecting frame 200. The fixed connection of the high-strength pressing component 300 to the high-strength connecting frame can reduce the stress on the main housing 100, thereby further reducing the strength requirements of the main housing 100.

[0031] Current chest compression machines suffer from ergonomic design flaws. They typically apply pressure to the patient using a planar force distribution method. However, this design is ill-suited for patients with breast tissue protrusion (such as women). Planar force application results in support points on both sides upon initial contact, causing effective pressure to be dispersed between these points instead of being concentrated in the chest cavity. This concentrated pressure at both support points also increases the risk of skin and soft tissue injury.

[0032] Figure 2This is a side view of a cardiopulmonary resuscitation (CPR) compression device according to one embodiment of this application. In one embodiment, the compression assembly 300 includes connecting portions 310 and compression portions 320 at both ends. The connecting portions 310 extend with a preset radius of curvature to form a structure with a preset arched feature. The compression portions 320 are fixedly connected to the connecting frame 200 through the connecting portions 310 on both sides. The arched design of the connecting portions 310 can provide the compression assembly 300 with the necessary elasticity and strength, help absorb the impact force generated during compression, and ensure that the force can be smoothly transmitted from the connecting frame to the compression portions. On the other hand, it can also extend away from the bottom surface of the main housing 100, thereby creating a preset distance between the compression portions 320 and the main housing 100.

[0033] The connecting portions 310 at both ends securely fix the pressing part 320 to the connecting frame 200, while maintaining a preset distance between it and the bottom surface of the main housing 100 to ensure heat dissipation space and prevent heat conduction to the patient or affecting the performance of the device. Through the cooperation of the connecting portions 310 at both ends of the pressing assembly 300 with the pressing part 320, the pressing assembly 300 forms an arc-shaped boss relative to the bottom of the main housing 100, and there is a certain gap inside the arc-shaped boss.

[0034] The compression component 300 protrudes beyond the bottom of the main housing 100 by a predetermined distance. This spacing between the compression component 300 and the bottom surface of the main housing 100 creates not only a heat dissipation space but also an arc-shaped protrusion. The arc between the compression component 300 and the bottom surface of the main housing 100 ensures that when compressing the chest cavity of a patient with breast tissue protrusion, the compression component 300 first contacts the center of the chest cavity, applying pressure to the center and increasing the degree of chest cavity deformation. The arc formed by the compression component 300 and the bottom of the main housing 100 conforms to the breast tissue protrusion, ensuring that the force point of the CPR compression device remains in the center of the chest cavity, preventing force dispersion by the sides. By rationally designing the shape of the compression component 300 as a protruding compression head, sufficient compression force can be ensured while minimizing the risk of damage to the patient's skin and soft tissues.

[0035] In one embodiment, the width of the pressing part 320 is greater than the width of the connecting part 310. The wider pressing part 320 means a larger contact area with the patient's chest cavity, allowing for a more even distribution of the pressing force across the entire contact surface, ensuring the effectiveness of the compression operation. It also prevents excessive stress concentration, thereby reducing the risk of injury to the patient's skin and soft tissues. Although the connecting part 310 is designed to be narrower than the pressing part 320, through appropriate material selection (such as high-strength plastics or metals) and an arched design, it still ensures that the connecting part 310 has sufficient strength to withstand and transmit the pressing force, while reducing overall weight for ease of carrying and use.

[0036] In one embodiment, the pressing components 300 may be symmetrically distributed along a longitudinal central axis. Symmetrical distribution of the pressing components 300 along their longitudinal central axis can refer to the pressing portion 320 and the connecting portion 310 having the same shape, size, and material properties on both sides of the central axis. Because the pressing components 300 have identical structures on both sides of the central axis, the force applied to the pressing components 300 can be evenly distributed, avoiding force imbalance caused by asymmetry, thereby ensuring a smoother and more effective pressing action. The symmetrical design also increases the overall stability of the structure and reduces the possibility of tilting or shifting during use.

[0037] Figure 3 This is a bottom view schematic diagram of a cardiopulmonary resuscitation (CPR) compression device according to one embodiment of this application. In one embodiment, the compression part 320 has a planar structure and is parallel to the bottom surface of the main housing 100. The planar design of the compression part 320 ensures that the compression force applied by the CPR compression device is evenly distributed on the patient's chest cavity surface in contact with the compression part 320 during each compression, improving the compression effect while reducing potential damage to the patient's skin and muscles. Simultaneously, the parallelism between the compression part 320 and the bottom surface of the main housing 100 ensures the stability and consistency of the compression action during use.
