Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cardiopulmonary resuscitation training device. Background Art

[0002] An AED (Automated External Defibrillator) is a medical device used to rescue patients with cardiac arrest. Usually, during the use of an AED, two electrode pads need to be attached to predetermined positions on the patient's body. The device collects the patient's electrocardiogram (ECG) signals through the two electrode pads, analyzes the patient's ECG signals, and determines whether the patient is suitable for defibrillation by electric shock.

[0003] A cardiopulmonary resuscitation simulator is a teaching tool created using medical simulation technology. It can be used to simulate clinical scenarios and patients, replacing real patients for clinical teaching and educational practice. Conducting medical model teaching can improve the practical hands-on ability of trainees, effectively solve the problem of "emphasizing theory over practice", and is of great significance for training medical rescue personnel.

[0004] When conducting medical model teaching on cardiopulmonary resuscitation, training medical rescue personnel to accurately attach two electrode pads to the set positions on the simulator is one of the important training objectives. In the prior art, NFC tags are set on the simulated skin, and the defibrillation training device can identify the NFC tags and determine the attachment effect of the electrode pad assembly in the defibrillation training device on the human model according to the tag information.

[0005] NFC, Near Field Communication technology, usually has an effective communication distance within 4 cm. Currently, NFC on the market is divided into NFC with an etching process and NFC with a flexible PCB process. The NFC with an etching process has low coating ductility and will break when the skin is bent, resulting in an open circuit of the coil and failure. For the NFC with a flexible PCB, the copper coil has a certain ductility and can fit the skin during bending. Under the condition of repeated bending at 180°, it will not break. Therefore, the flexible PCB NFC is more suitable for skin adhesion.

[0006] NFC has a very small chip that is easily damaged when impacted, so it cannot be directly added during the injection molding process. On the one hand, the injection molding temperature is nearly 200 degrees Celsius, which will directly damage the NFC finished product; on the other hand, the impact generated during the injection molding process will also make it difficult to control the position of the NFC finished product.

[0007] At present, glue is mostly used to attach the NFC to the mannequin. However, after the glue cures, it becomes hard, making the flexibility of the simulated skin poor. After repeated deformation, the glue is prone to embrittlement and detachment. Silicone glue is not easy to cure, but has a poor sticking effect and is easy to fall off. Therefore, no matter which glue is used, there is a risk of glue failure, and during the assembly process, there will also be risks such as glue overflow, insufficient glue, difficult operation, and long curing time. Summary of the Invention

[0008] Based on this, in view of the above technical problems existing in the prior art, it is necessary to provide a cardiopulmonary resuscitation training device that uses an existing NFC product of a flexible PCB and is combined with the simulated skin of a mannequin through a protective layer, which is safe, reliable, and does not fall off.

[0009] The utility model adopts the following technical solutions:

[0010] A cardiopulmonary resuscitation training device includes a mannequin, a simulated skin, and an NFC component. The simulated skin is detachably arranged on the mannequin. The NFC component is arranged on the simulated skin and is located between the simulated skin and the mannequin. The NFC component includes an NFC device and a protective layer for fixing the NFC device on the simulated skin and playing a protective role. The NFC device is located between the simulated skin and the protective layer.

[0011] The utility model uses an existing NFC product of a flexible PCB and is combined with the simulated skin of a mannequin through a protective layer, which is safe, reliable, and does not fall off.

[0012] Preferably, the protective layer includes an installation area and a fixing area. The fixing area is arranged around the installation area. The NFC device is fixedly arranged in the installation area. The fixing area is fixed on the simulated skin by a heating welding method. The utility model combines the protective layer with the simulated skin of the mannequin by a heating welding method, which is safe, reliable, and does not fall off.

[0013] Preferably, the installation area is circular, and the fixing area is an annular shape arranged around the installation area. The utility model is arranged in this way to prevent unconnected points from appearing at the corners during the fixation of the fixing area on the one hand, and to prevent warping and detachment from easily occurring at the corners during use on the other hand.

[0014] Preferably, the number of NFC devices is greater than or equal to 2. The utility model is arranged in this way. The NFCs work independently, which can avoid the situation that the overall training device cannot be used when a single NFC fails, and multiple NFCs increase the range of data that can be read, while a single NFC has a range limitation.

[0015] Preferably, the number of NFC devices is 3, and the 3 NFC devices are arranged in an equilateral triangle on the installation area. The 3 NFC devices of the utility model are arranged at an angle, which can effectively prevent the devices from being bent.

[0016] Preferably, the shortest distance between the edge of the NFC device and the edge of the installation area is 2-4 mm. If the shortest distance between the edge of the NFC device and the edge of the installation area is too close, it will cause damage to the NFC device when preparing the fixing area. If the shortest distance between the edge of the NFC device and the edge of the installation area is too far, it will result in an overly large installation area and the NFC device will not be firmly fixed.

[0017] Preferably, the width of the fixing area is 3-6 mm. If the fixing area is too wide, it will cause waste of materials. If the fixing area is too narrow, it will lead to insecure fixation and the NFC device will fall off.

[0018] Preferably, an adhesive layer is provided between the NFC device and the protective layer. In the present utility model, the position of the NFC device on the protective layer is fixed through the adhesive layer to prevent the NFC device from moving and affecting the subsequent fixing area.

[0019] Preferably, the side of the NFC device with the chip faces the simulated skin.

[0020] Preferably, the thickness of the simulated skin is 2-6 mm, and the Shore hardness is 30-50 degrees. By defining the simulated skin with a certain thickness, certain softness and hardness, and the direction of the NFC device, the present utility model can well protect the small chip of the NFC.

[0021] Preferably, the NFC assembly includes a first NFC assembly and a second NFC assembly. The first NFC assembly is located in the chest area below the right collarbone of the human body model, and the second NFC assembly is located in the rib area below the left chest of the human body model.

[0022] Due to the adoption of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0023] 1. The present utility model utilizes the existing NFC product of the flexible PCB and combines it with the simulated skin of the human body model through the protective layer, which is safe, reliable and does not fall off;

[0024] 2. The limitation of the number, angle and position of the installation of the NFC device in the present utility model ensures the effective operation of the training tool, and the NFC device is not easily bent;

[0025] 3. The present utility model can well protect the small chip of the NFC through the simulated skin with a certain thickness and a certain softness and hardness. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Currently, glue is mostly used to attach the NFC to the mannequin. However, after the glue cures, it becomes hard, making the flexibility of the simulated skin poor. After repeated deformation, the glue is prone to embrittlement and peeling. Silicone glue is not easy to cure, but has a poor pasting effect and is easy to fall off. Therefore, no matter which glue is used, there is a risk of glue failure, and during the assembly process, there will also be risks such as glue overflow, insufficient glue, difficult operation, and long curing time.

[0035] On this basis, the present utility model provides a cardiopulmonary resuscitation training device, including a mannequin, a simulated skin, and an NFC component. The simulated skin is detachably arranged on the mannequin, and the NFC component is arranged on the simulated skin and located between the simulated skin and the mannequin. The NFC component includes an NFC device and a protective layer for fixing the NFC device on the simulated skin and playing a protective role. The NFC device is located between the simulated skin and the protective layer.

[0036] The present utility model utilizes the existing NFC product of flexible PCB and combines it with the simulated skin of the mannequin through the protective layer, which is safe, reliable, and does not fall off.

[0037] The following describes the present utility model in detail with specific embodiments.

[0038] As Figures 1-3 shown, a cardiopulmonary resuscitation training device in this embodiment includes a mannequin 1, a simulated skin 2, and an NFC component 3.

[0039] As Figure 1 shown, the simulated skin 2 is detachably arranged on the mannequin 1. Specifically, the simulated skin 2 is detachably arranged on the chest and abdomen of the mannequin 1.

[0040] The NFC component 3 is arranged on the simulated skin 2 and located between the simulated skin 2 and the mannequin 1, that is, the NFC component 3 is arranged on the side of the simulated skin 2 close to the mannequin 1, or it can be said that the NFC component 3 is arranged on the inner side of the simulated skin 2. Specifically, as Figure 2 marked by the circled position in

[0041] As Figure 3 shown, each NFC component 3 includes an NFC device 31 and a protective layer 32 for fixing the NFC device 31 on the simulated skin 2 and playing a protective role. The NFC device 31 is located between the simulated skin 2 and the protective layer 32, that is, the NFC device 31 is located on the side of the protective layer 32 close to the simulated skin 2.

[0042] In this embodiment, an adhesive layer is provided between the NFC device 31 and the protective layer 32, which is used to fix the NFC device 31 on the protective layer 32. In this embodiment, the NFC device 31 is fixed on the protective layer 32 through the adhesive layer to prevent the NFC device 31 from moving and affecting the subsequent fixed area.

[0043] In this embodiment, the protective layer 32 includes an installation area 321 and a fixed area 322, and the fixed area 322 is arranged around the installation area 321. Specifically, the installation area 321 is circular, and the fixed area 322 is an annular shape arranged around the installation area 321. The NFC device 31 is fixedly arranged in the installation area 321, and the fixed area 322 is fixed on the simulated skin 2 by means of heat welding. The utility model combines the protective layer to the simulated skin of the human model by means of heat welding, which is safe, reliable and does not fall off.

[0044] In this embodiment, the number of NFC devices 31 is greater than or equal to 2. With such a setting in this embodiment, when the NFCs work independently, it can be avoided that when a single NFC fails, the overall training tool cannot be used, and multiple NFC devices 31 increase the range of data that can be read. There will be a range limit for a single NFC device 31. Specifically, the number of NFC devices 31 is 3, and the 3 NFC devices 31 are arranged in an equilateral triangle on the installation area 321. In this embodiment, the 3 NFC devices 31 are arranged at an angle, which can effectively prevent the devices from bending.

[0045] In this embodiment, the projection of the NFC device 1 on the plane is located within the projection of the installation area 321 on the plane, and the shortest distance a between the edge of the NFC device 1 and the edge of the installation area 321 is 2 - 4 mm. If the shortest distance between the edge of the NFC device 31 and the edge of the installation area 31 is too close, it will cause damage to the NFC device 31 when preparing the fixed area 322 by heat welding. If the shortest distance a between the edge of the NFC device 31 and the edge of the installation area 321 is too far, it will cause the installation area 321 to be too large, and the NFC device 31 will not be fixed firmly and will shake.

[0046] In this embodiment, the width b of the fixed area 322 is 3 - 6 mm. If the fixed area 322 is too wide, it will cause waste of materials. If the fixed area 322 is too narrow, the protective layer 32 will not be fixed firmly, and further the NFC device 31 will fall off.

[0047] In this embodiment, the side of the NFC device 31 with the chip faces the simulated skin 2. The thickness of the simulated skin 2 is 2 - 6 mm, and the Shore hardness is 30 - 50 degrees. Preferably, the thickness of the simulated skin 2 is 4 mm and the Shore hardness is 40 degrees. In this embodiment, by defining the simulated skin with a certain thickness and a certain softness and hardness and the direction of the NFC device, the small chip of the NFC can be well protected.

[0048] In this embodiment, the simulated skin 2 is made of PVC material, and the protective layer 32 is made of PVC material.

[0049] The manufacturing method of the training tool in this embodiment includes the following steps:

[0050] First, the NFC device 31 is pre-attached to the protective layer 32 at a certain position and orientation through the adhesive layer, and then the NFC device 31 is placed on the installation area 321 of the simulated skin 2. Under the conditions of high temperature and high pressure, the protective layer 32 and the simulated skin 2 are fused, and the NFC device 31 is sandwiched in the middle.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
