Description

Technical Field

[0001] This utility model relates to an educational training device, particularly an emergency teaching and training device, specifically an obese cardiopulmonary resuscitation (CPR) training device. Background Technology

[0002] First aid, also known as pre-hospital emergency care, refers to the timely initial rescue provided to patients before the arrival of medical personnel in order to save their lives. First aid demonstrations, conducted by professional first aid trainers, involve using simulations that closely resemble actual first aid situations to guide trainees in learning and mastering first aid techniques and procedures in advance, enabling them to take quick and accurate measures to save lives in emergencies.

[0003] With the obesity rate rising annually, the potential risk of cardiac and respiratory arrest is extremely high in obese individuals, making cardiopulmonary resuscitation (CPR) more likely to be used in this population. However, obese patients often exhibit physical characteristics during CPR, such as "neck fat accumulation, enlarged tongue, difficulty in airway opening, upward displacement of the heart, thick chest wall fat, and insufficient compression depth." Furthermore, obese patients often require specific procedures during CPR, such as the ramping position (elevating the patient's shoulders and back so that the external auditory canal is horizontal with the sternal notch) and the advice against moving the patient to the ground to avoid delaying rescue. This makes it difficult for standard CPR training devices to meet the specific operational needs of obese patients in actual emergency situations. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing teaching and practice devices being unable to adapt to obese patients and the inability to evaluate teaching effectiveness in real time, by designing an obese-type cardiopulmonary resuscitation (CPR) training device. It is a special first-aid demonstration device designed for obese individuals, capable of demonstrating CPR to obese people in different scenarios, while simultaneously detecting whether the first-aid personnel's actions are standard, thereby assisting trainees in better mastering accurate CPR techniques.

[0005] One of the technical solutions of this utility model is:

[0006] An obese cardiopulmonary resuscitation (CPR) training device includes a head and neck component 1, a chest component 2, and an abdominal component 3. A front baffle 4 is installed between the head and neck component 1 and the chest component 2, and a rear baffle 5 is installed between the chest component 2 and the abdominal component 3, which are hinged together by a hinge pin 6. A simulated sternal plate 19 spanning the head and neck component 1 and the chest component 2 is installed on the front baffle 4. The device is characterized in that an airway 7 is installed in the head and neck component 1, and a simulated enlarged tongue block 9 is installed at the air inlet end of the airway 7 via a pivot pin 8. Artificial respiration requires first using... The tongue hypertrophy simulation block 9 can be rotated by hand or tool to blow air into the airway 7. The other end of the airway 7 passes through the front baffle 4 and extends into the cavity of the chest component 2. A neck fat simulation body 14 is installed on the upper part of the head and neck component 1. A sealed elastic box 10 that can be compressed and rebound as a whole is installed in the chest component 2. The sealed elastic box 10 is connected to the airbag 13 that simulates the blood supply to the brain in the head and neck component 1 through the trachea 12 that passes through the front baffle 4. An anterior chest fat simulation body 15 is installed on the upper part of the chest component 2.

[0007] The air outlet of the air passage 7 is equipped with a filter screen 11.

[0008] The lower parts of the chest component 2 and the abdominal component 3 are connected with anti-slip stripes 22.

[0009] The second technical solution of this utility model is:

[0010] An obese-type cardiopulmonary resuscitation (CPR) training device includes a head and neck component 1, a chest component 2, and an abdominal component 3. A front baffle 4 is installed between the head and neck component 1 and the chest component 2, and a rear baffle 5 is installed between the chest component 2 and the abdominal component 3, which are hinged together by a hinge pin 6. A simulated sternal plate 19 spanning the head and neck component 1 and the chest component 2 is installed on the front baffle 4. The device is characterized in that: an airway 7 is installed in the head and neck component 1; the air inlet end of the airway 7 is fitted with a tongue hypertrophy simulation block 9 via a pivot pin 8; during artificial respiration, the dummy's chin must be lifted by hand to rotate the tongue hypertrophy simulation block 9 before air can be blown into the airway 7; the other end of the airway 7 passes through the front baffle 4 and extends into the cavity of the chest component 2; a neck fat simulation body 14 is installed on the upper part of the head and neck component 1; and a sealed structure capable of overall compression and rebound is installed in the chest component 2. The sealed elastic box 10 is connected to an airbag 13 simulating blood supply to the brain, which is installed in the head and neck component 1, through an air tube 12 passing through the front baffle 4. A front chest fat simulator 15 is installed on the upper part of the chest component 2. The front chest fat simulator 15 consists of two parts, one of which is made of a transparent material and has a compression position display 17 installed at its lower part. A pressure sensor 18 is installed in the airbag 13. When the practitioner presses the sealed elastic box 10 with a set pressure, the pressure sensor 18 controls whether the compression position display 17 lights up to indicate whether the compression has reached the target value. The pressure sensor 18 and the compression position display 17 are powered by a battery 20 installed in the abdominal component 3 and electrically connected to a CPR detection device 21, where CPR is the abbreviation for cardiopulmonary resuscitation.

[0012] The lower parts of the chest component 2 and the abdominal component 3 are connected with anti-slip stripes 22.

[0013] The beneficial effects of this invention are: it can accurately simulate the core physical characteristics of obese patients, such as "fat accumulation in the neck and thickened chest wall," as well as special emergency requirements such as the ramping position and the prohibition of moving them to the ground, thus solving the core problem that existing normal-sized models cannot be adapted to emergency demonstrations for obese individuals. It is easy to operate, highly adaptable to real-world scenarios, and includes a movement standardization check, allowing trainees to master the key difficulties of emergency care for obese individuals in non-emergency situations, thereby optimizing the training effect.

[0018] The following structural drawings and embodiments further illustrate this utility model.

[0019] Example 1.

[0020] like Figure 1 , Figure 3 As shown.

[0021] An obese-type cardiopulmonary resuscitation (CPR) training device includes a head and neck component 1, a chest component 2, and an abdominal component 3, such as... Figure 1 As shown, a front baffle 4 is installed between the head and neck component 1 and the chest component 2, and a rear baffle 5 is installed between the chest component 2 and the abdominal component 3, which are hinged together by a hinge pin 6. The hinge pin 6 indicates that the spine can bend partially forward or backward to better fit on objects such as sofas. A simulated sternal plate 19 spanning the head and neck component 1 and the chest component 2 is installed on the front baffle 4. Anti-slip stripes 22 are connected to the lower parts of the chest component 2 and the abdominal component 3. An airway 7 is installed in the head and neck component 1, and a filter screen 11 is installed at the outlet end of the airway 7. A tongue hypertrophy simulation block 9 is installed at the inlet end of the airway 7 via a pivot 8. During artificial respiration, the upper jaw of the dummy must first be lifted by hand to rotate the tongue hypertrophy simulation block 9 and open the airway 7 before air can be blown into it. The pivot ensures that the tongue is close to the lower jaw. If the patient's head is not tilted back, the tongue hypertrophy will block the airway. If the patient's head is tilted back, the airway can be opened. The other end of the airway 7 passes through the front baffle 4 and extends into the cavity of the chest component 2. A neck fat simulator 14 is installed on the upper part of the head and neck component 1. A sealed elastic box 10 capable of overall compression and rebound is installed in the chest component 2. This sealed elastic box 10 is connected to an airbag 13 simulating blood supply to the brain in the head and neck component 1 via an air tube 12 passing through the front baffle 4. An anterior chest fat simulator 15 is installed on the upper part of the chest component 2. The model surface is made of soft sponge to simulate breast sagging, so it is impossible to determine the pressure position by connecting the midpoints of the two nipples. There is a plastic plate (i.e., simulating the sternal plate 19) inside the chest sponge block. Figure 3 This is used to simulate the sternum area so that the sliding method can be used to determine the compression position.

[0022] Example 2.

[0023] like Figure 2 , Figure 3 As shown.

[0024] An obesity-related cardiopulmonary resuscitation (CPR) training device includes a head and neck component 1, a chest component 2, and an abdominal component 3. A front baffle 4 is installed between the head and neck component 1 and the chest component 2, and a rear baffle 5 is installed between the chest component 2 and the abdominal component 3, all hinged together by a hinge pin 6. The hinge pin 6 allows the spine to bend partially forward or backward for better fit on objects such as sofas. A simulated sternal plate 19 is mounted on the front baffle 4, spanning the head and neck component 1 and the chest component 2. Figure 3 As shown, this is because the model surface uses soft sponge to simulate breast sagging, making it impossible to determine the compression position by connecting the midpoints of the two nipples. Inside the chest sponge block is a plastic plate (i.e., a simulated sternal plate 19) to simulate the sternum area, allowing the sliding method to determine the compression position. The lower parts of the chest component 2 and the abdominal component 3 are connected by anti-slip stripes 22. An airway 7 is installed in the head and neck component 1. The air inlet of the airway 7 is fitted with a tongue hypertrophy simulation block 9 via a pivot 8. During artificial respiration, the tongue hypertrophy simulation block 9 needs to be rotated by hand or tool before air can be blown into the airway 7. The other end of the airway 7 passes through the front baffle 4 and extends into the cavity of the chest component 2. The air outlet of the airway 7 is equipped with a filter screen 11 and an airflow sensor 16. Figure 2 As shown, the airflow sensor 16 is battery-powered and electrically connected to the CPR detection device 21. A neck fat simulator 14 is installed on the upper part of the head and neck component 1; a sealed elastic box 10 capable of overall compression and rebound is installed in the chest component 2. This sealed elastic box 10 is connected to an airbag 13 simulating brain blood supply in the head and neck component 1 via an air tube 12 passing through the front baffle 4. An anterior chest fat simulator 15 is installed on the upper part of the chest component 2. The anterior chest fat simulator 15 consists of two parts, one of which is made of a highly transparent material. A compression position display 17 is installed at its lower part. The compression position display 17 can use a built-in high-brightness LED light or a light-emitting module. Light can penetrate the sponge tissue, making the compression area display a clear light signal (such as a specific color light spot or halo), intuitively indicating the correct compression position. Transparent material combination: Parts of the sponge tissue are made of a semi-transparent material, or the display surface is designed to be transparent, combined with internal light-emitting elements, allowing light to pass through for easy observation. A pressure sensor 18 is installed in the airbag 13. When the practitioner presses the pressure of the sealed elastic box 10 to the set value, the pressure sensor 18 controls whether the pressing position display 17 lights up to indicate whether the pressing has reached the standard. The pressure sensor 18 and the pressing position display 17 are powered by the battery 20 installed in the abdominal component 3 and are electrically connected to the CPR detection device 21.

[0025] In this embodiment, the specific operation is as follows: After turning on switch 23 (which can be installed on the abdominal component 3), when the operator performs chest compressions on the human model, the spring in the compression spring box contracts, and gas enters the airbag from the compression spring box through the gas passage. The pressure sensor in the airbag increases pressure, and when a predetermined value is reached, the indicator light illuminates, indicating that the compression depth is qualified. When the operator clears foreign objects from the human model's mouth and opens the airway, the Ramping body positioning tongue simulation component is used to move the tongue forward naturally, fully opening the airway. When the operator performs artificial respiration on the human model, gas enters the chest cavity from the blowing port through the trachea after being filtered for water vapor, causing the chest cavity to rise naturally to achieve the simulation effect.

[0026] The parts not covered by this utility model are the same as or can be implemented using existing technology.
