Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a chest compression simulation device for simulating a human. Background Art

[0002] According to cardiopulmonary resuscitation (CPR) guidelines, the recommended chest compression depth for adults is 5-6 cm (about 2 inches). This is to ensure that the compression can effectively promote blood circulation while avoiding causing unnecessary injuries.

[0003] The chest compression simulation device is a device that simulates the mechanical structure of the real human chest cavity to help medical staff learn chest compression operations.

[0004] Existing chest cavity simulation compression devices are often set in a simulator, and the size of the simulator should be roughly the same as that of an ordinary adult. At the same time, the simulator is also provided with components such as a depth measurement mechanism, a lung bag, a control panel and a battery, which leads to a tight space inside the simulator. Due to the provisions of the cardiopulmonary resuscitation guidelines and the constraints of the simulator's internal space, the current chest cavity simulation compression device for a simulator is often designed to have a compression depth of no more than 6 cm. After pressing to 6 cm, it will be stuck by other structures and cannot be pressed down. However, in the actual first aid process, operators often have the situation of pressing too deeply (more than 6 cm). If the simulator in the prior art is used for training, then the existing simulator cannot sense and feedback the state of pressing too deeply.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] In view of this, the embodiments of the present application provide a chest simulation compression device for simulating a human in order to solve the above-mentioned problems existing in the structural design of the chest simulation compression device in the background art.

[0007] The embodiment of the present application provides a chest compression simulation device for simulating a human, comprising:

[0008] a first plate;

[0009] a second plate;

[0010] The telescopic member includes a first column and a second column that are movable relative to each other, wherein the first column and the second column are sleeved together; the first column is fixed to the first plate, and the second column is fixed to the second plate;

[0011] a buffer pad aligned with an end portion of the first column or the second column so as to be in contact with the end portion of the first column or the second column;

[0012] a spring, wherein when compressed, the spring is capable of exerting a force that moves the first plate and the second plate away from each other;

[0013] When the second plate is pressed by the user, it can move from the initial position to the first plate. When the distance between the second plate and the initial position is less than a preset length L1, the spring is compressed, and the distance between the end of the second column and the buffer pad is greater than 0; when the distance between the second plate and the initial position is greater than or equal to L1, the spring is compressed, and the end of the second column abuts against the buffer pad; L1 is 60mm to 70mm.

[0016] In an optional embodiment, the spring is sleeved outside the first column and the second column, and two ends of the spring respectively abut against the first plate and the second plate.

[0017] In an optional embodiment, the second column includes a second column body and an arc-shaped transition portion located at one end of the second column body, and the arc-shaped transition portion is fixed to the second plate body; when the end of the second column abuts the buffer pad, the distance between the second plate body and the initial position is less than the limiting length L2; when the second plate body is located at the initial position, the distance between the arc-shaped transition portion and the first column is greater than L2.

[0018] In an optional embodiment, the spring is located inside the first column and the second column, and both ends of the spring respectively abut the first plate and the second plate, or both ends of the spring respectively abut the inner walls of the first column and the second column.

[0019] In an optional embodiment, the buffer pad is made of one or more materials selected from rubber, silicone, plastic, fiber, and sponge.

[0020] In an optional embodiment, the buffer pad is fixed to one side of the first plate or an end of the first column away from the second column, and the buffer pad is aligned with the end of the second column along the axial direction of the second column;

[0021] Alternatively, the buffer pad is fixed to one side of the second plate and arranged around the second column, and the buffer pad is aligned with the end of the first column along the axial direction of the second column.

[0022] In an optional embodiment, the chest simulation compression device for simulating a human further includes a buffer sheet, and the buffer sheet is fixed to the end of the first column or the second column.

[0023] The embodiment of the present application provides a chest compression simulation device for simulating a human. Through the setting of the buffer pad and the design of the preset length L1, when the second plate body is pressed by the user but does not exceed the preset length L1, the spring is compressed normally, and the pressing force value is fed back, thereby ensuring the training effect; and when the second plate body is pressed by the user beyond the preset length L1, the end of the second column contacts the buffer pad, reducing the impact sound of the second column and improving the user experience; in the present application, the preset length L1 is set at 60mm~70mm, which can feedback the user that the pressing is too deep.

[0040] In order to fully understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0041] Example 1

[0042] This embodiment provides a chest compression simulation device for simulating a human being, such as Figure 1 As shown, it includes: a first plate body 1, a second plate body 3, a telescopic member, a buffer pad 5, and a spring 6.

[0043] Among them, one of the first plate 1 and the second plate 3 serves as a supporting plate and is used to be fixed on the simulated human back, and the other serves as a force-bearing plate for medical staff to train pressing and is used to be fixed on the simulated human chest.

[0044] The telescopic member includes a first column 2 and a second column 4 that are movable relative to each other, and the first column 2 and the second column 4 are mutually sleeved; the first column 2 is fixed to the first plate body 1, and the second column 4 is fixed to the second plate body 3. The form of the mutual sleeve connection between the first column 2 and the second column 4 can be that the first column 2 is sleeved outside the second column 4, or the second column 4 is sleeved outside the first column 2. The first column 2 or the second column 4 can both be hollow tubes with open ends, or both can be hollow tubes with one end closed and the other end open, or one can be a hollow tube and the other a solid tube. In short, the sleeve structure of the first column 2 or the second column 4 can satisfy the requirement that the two can move relative to each other.

[0045] The cushioning pad 5 is aligned with the end of the first pillar 2 or the second pillar 4 so as to be in contact with the end of the first pillar 2 or the second pillar 4. This alignment refers to alignment along the direction of movement of the first pillar 2 or the second pillar 4. That is, the cushioning pad 5 is located along the path of movement of the first pillar 2 or the second pillar 4, so that the cushioning pad 5 can provide cushioning for the moving first pillar 2 or the second pillar 4. Since the first pillar 2 and the second pillar 4 are interlocked in this embodiment, the direction of movement is also the axial direction of the first pillar 2 or the second pillar 4.

[0046] When compressed, the spring 6 exerts a force that moves the first plate 1 and the second plate 3 apart. The spring 6 has an initial length at which it generates no elastic force. However, when a user presses the first plate 1 or the second plate 3, the spring 6 shortens, bringing the first plate 1 and the second plate 3 closer together. The spring 6 provides the elastic force that moves the first plate 1 and the second plate 3 apart and allows them to return to their original position.

[0047] In the chest compression simulation device for simulating a human being of this embodiment, the second plate 3 can move from an initial position toward the first plate 1 when pressed by a user. When the distance between the second plate 3 and the initial position is less than a preset length L1, the spring 6 is compressed, and the distance between the end of the second column 4 and the cushion 5 is greater than 0. When the distance between the second plate 3 and the initial position is greater than or equal to L1, the spring 6 is compressed, and the end of the second column 4 abuts against the cushion 5. L1 is the designed standard compression depth. The recommended compression depth in the cardiopulmonary resuscitation guidelines is 50 to 60 mm. Therefore, the length of L1 can refer to the requirements in the cardiopulmonary resuscitation guidelines. Considering that the chest compression simulation device for simulating a human being needs to simulate and provide feedback on the state of excessive compression, the length of L1 can be adaptively expanded. In this embodiment, the preset length L1 is set at 60 mm to 70 mm, which can provide feedback to the user on the state of excessive compression.

[0048] The chest compression simulation device for simulating a human being in this embodiment, through the arrangement of the above-mentioned buffer pad 5 and the design of the preset length L1, when the second plate body 3 is pressed by the user but does not exceed the preset length L1, the spring 6 compresses normally, feedbacks the pressing force value, simulates the elasticity of the chest cavity, and ensures the training effect; and when the second plate body 3 is pressed by the user beyond the preset length L1, the end of the second column 4 contacts the buffer pad 5, reducing the impact sound of the second column 4, which can improve the user experience; the preset length L1 is set at 60mm~70mm, which exceeds the compression depth recommended for adults in the cardiopulmonary resuscitation (CPR) guidelines when performing chest compressions, and can feedback the user that the compression is too deep.

[0049] In an optional embodiment, if Figure 1As shown, the spring 6 is sleeved outside the first column 2 and the second column 4, with the two ends of the spring 6 respectively abutting the first plate 1 and the second plate 3. In this embodiment, sleeved outside the first column 2 and the second column 4, the spring 6 is easy to install and can also have a certain limiting effect on the spring 6, facilitating the stability of the spring 6. The two ends of the spring 6 respectively abutting the first plate 1 and the second plate 3 can provide good support for the first plate 1 and the second plate 3.

[0050] In an optional embodiment, if Figure 1 As shown, the second column 4 includes a second column body 41 and an arcuate transition portion 42 located at one end of the second column body 41. The arcuate transition portion 42 is fixed to the second plate 3. When the end of the second column 4 abuts the buffer pad 5, the distance between the second plate 3 and the initial position is less than the limit length L2. When the second plate 3 is in the initial position, the distance between the arcuate transition portion 42 and the first column 2 is greater than L2. In this embodiment, the difference in thickness of the buffer pad 5 from its original thickness to its minimum thickness is L2-L1. Therefore, when the end of the second column 4 abuts the buffer pad 5, the distance between the second plate 3 and the initial position is less than the limit length L2. Because the distance between the arcuate transition portion 42 and the first column 2 is greater than L2 when the second plate 3 is in the initial position, in this solution, when the buffer pad 5 is compressed to its minimum thickness, the arcuate transition portion 42 will not impact the first column 2, thereby avoiding noise. The distance between the arcuate transition portion 42 and the first pillar 2 is the distance between the adjacent sides of the two, that is, the distance between the points where the two would first contact each other in the event of a collision. The thickness difference between the cushioning pad 5 from its original thickness to its minimum thickness depends on the specific material and dimensions of the cushioning pad 5 and can be selected by those skilled in the art as needed.

[0051] In an optional embodiment, the chest compression simulation device for simulating a human being of this embodiment has L1 ranging from 63 mm to 70 mm, preferably 63 mm, 63.5 mm, 64 mm, 64.5 mm, 65 mm, 65.5 mm, 66 mm, 66.5 mm, 67 mm, 67.5 mm, 68 mm, 68.5 mm, 69 mm, 69.5 mm, or 70 mm, and more preferably 65 mm. L2 ranges from 65.5 mm to 70 mm. This size design is adaptively adjusted based on cardiopulmonary resuscitation guidelines and is suitable for compression simulation training and feedback to users when they press too deeply.

[0052] In an optional embodiment, the cushion pad 5 of the present embodiment is made of one or more of rubber, silicone, plastic, fiber, and sponge. The cushion pad 5 is made of a flexible material to reduce impact and noise.

[0053] In an optional embodiment, if Figure 1 As shown, the buffer pad 5 is fixed to the first plate body 1 and is aligned with the end of the second column 4 along the axial direction of the second column 4. In this embodiment, the buffer pad 5 can effectively cushion the end of the second column 4, reducing the impact when the end of the second column 4 approaches the first plate body 1. It will be understood that if the end of the first column 2 away from the second column 4 is a closed structure, the buffer pad 5 can be installed at the end of the first column 2 away from the second column 4 to similarly cushion the end of the second column 4.

[0054] In an optional embodiment, the human chest compression simulation device further includes a buffer sheet secured to the end of the first column 2 or the second column 4. In this embodiment, securing the buffer sheet to the end of the first column 2 or the second column 4 can also reduce the noise caused by the end of the first column 2 or the second column 4 impacting the first plate 1 or the second plate 3. The buffer sheet can be made of the same material as or different from the cushion 5.

[0055] In this embodiment, L1 is 65mm and L2 is 66mm as an example to describe the state changes of the chest compression device used to simulate human chest compression during a compression cycle. The process is as follows:

[0056] Initial state: the second plate 3 is at the initial position, and the spring 6 is at its original length;

[0057] Pressing within the designed stroke: the second plate 3 moves downward, the distance from the initial position is less than 65 mm, and the spring 6 is compressed;

[0058] Pressing beyond the designed stroke: The second plate 3 continues to descend, and the length from the initial position is greater than 65 mm. The spring 6 is compressed, and the end of the second column 4 abuts the buffer pad 5. The buffer pad 5 is compressed by 1 mm. The length of the second plate 3 from the initial position reaches 66 mm. At this time, the arc-shaped transition portion 42 does not contact the first column 2.

[0059] When the pressing force is removed, the spring 6 rebounds, and the second plate 3 moves upward and returns to its initial position.

[0060] Example 2

[0061] This embodiment provides a chest compression simulation device for simulating a human being, such as Figure 2 As shown, the difference from Example 1 is that the spring 6 is located inside the first column 2 and the second column 4, with its ends respectively abutting the first plate 1 and the second plate 3. In this solution, the spring 6 is internally positioned, utilizing the space within the first column 2 and the second column 4 to accommodate the spring 6, saving installation space and providing a position limit for the spring 6. Both the first column 2 and the second column 4 are through-holes, allowing the spring 6 to abut the first plate 1 and the second plate 3 at both ends.

[0062] It is understandable that in other embodiments, the first column 2 and the second column 4 can both be pipes with one end open and the other end closed, and the two ends of the spring 6 can respectively abut the inner walls of the closed ends of the first column 2 and the second column 4.

[0063] In an optional embodiment, if Figure 2 As shown, the buffer pad 5 is fixed to one side of the second plate 3 and arranged around the second column 4. The buffer pad 5 is aligned with the end of the first column 2 along the axial direction of the second column 4. In this embodiment, unlike the solution of Example 1, the buffer pad 5 is designed to be annular and arranged around the second column 4. It can withstand the impact of the end of the first column 2 and also play a buffering role when the second plate 3 is pressed.

[0064] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present application and do not limit the scope of protection of the patent application.
