Detailed Description

As shown in fig. 1 to fig. 11, the utility model mainly comprises a human body model 1, a pressing mechanism and a counting mechanism, and the following description is made in detail with reference to the accompanying drawings.

As shown in FIG. 1, the human body model 1 is the main body of the present invention, the human body model is the body part above the waist of the adult, and the human body model is made of silica gel material.

The pressing mechanism is arranged in the human body model and comprises a pressing plate 2 and a bottom plate 21 which are arranged up and down, and a pressing spring 22 and a positioning spring 23 which are arranged between the pressing plate and the bottom plate, as shown in fig. 2 and fig. 3, wherein the pressing plate and the bottom plate are both circular plates, the pressing spring is arranged at the axis position of the pressing plate, the positioning springs are four, the four positioning springs are uniformly arranged on the same circumference, and the pressing spring is positioned in the circle center of the circumference. The pressing plate and the bottom plate are both arranged inside the human body model, a fixed distance is reserved between the pressing plate and the bottom plate under the lifting action of the pressing spring and the positioning spring, and the pressing plate is horizontally arranged. The pressing plate is positioned at the top of the manikin and is positioned right above the middle-lower part of the sternum in the manikin, namely the position where the hands of the trainer are to be placed during the cardiac resuscitation.

When the heart resuscitation is performed, the palm is placed at the center of the pressing plate, and the position when the human body model is pressed is the most accurate; as shown in fig. 4, the pressing plate moves downward at this time, and the compression amount of the pressing spring is the same as that of the positioning spring. As shown in fig. 5, when most of the hand of the trainer contacts with the edge of the pressure plate during pressing, the pressure plate is in an inclined state, the compression amount of the positioning spring closest to the contact point of the hand of the trainer and the pressure plate is the largest, at this time, the compression amounts of the four positioning springs are different, and the compression amount of the positioning spring with the largest compression amount is greatly different from the compression amount of the positioning spring with the smallest compression amount. At this time, the compression amount of the pressing spring is between the compression amount of the positioning spring with the smallest compression amount and the compression amount of the positioning spring with the largest compression amount.

In order to facilitate detection of the compression amount of the positioning spring and the pressing spring, as shown in fig. 6, a first strain gauge is arranged on the pressing spring, a second strain gauge is arranged on the positioning spring, and the first strain gauge and the second strain gauge are in signal connection with a PLC controller located on the human body model. The first strain gauge is used for detecting the compression amount of the pressing spring, and the second strain gauge is used for detecting the compression amount of the positioning spring.

When cardiac resuscitation training is required, the trainer places the palm of the hand in the correct position on the manikin (i.e., the very center of the compression plate). When the palm is not in contact with the compression plate, the operation is seriously disqualified when the trainer performs the cardiac resuscitation. When the palm is contacted with the edge of the pressing plate, the compression amount of the pressing spring is between the compression amounts of the positioning springs, and the difference of the compression amounts of the positioning springs is large; this indicates that the trainer is not performing and the palm is not pressing in the correct position. When the palm contacts the center or a position close to the center of the pressing plate, the pressing plate keeps a horizontal posture and moves downwards, and the compression amounts of the pressing spring and the positioning spring are the same or slightly different, which indicates that the trainer finds an accurate pressing position. The human body model is provided with a display, and the display can display the compression amount of the pressing spring and the positioning spring.

When the trainer carries out heart resuscitation to patient, on guaranteeing that the hand is put in the position of correctness (lower part in the chest), for the position of placing of further standardizing the palm, as shown in figure 7, be equipped with a plurality of photosensitive sensor 3 at the top of clamp plate, photosensitive sensor is the multiunit, and the photosensitive sensor who sets up in groups evenly sets up on same circumference. In use, the trainer places the left hand on the press plate and then presses the right hand against the left hand, as shown in figure 8. At the moment, the photosensitive sensor covered by the left hand converts the optical signal into a current signal and transmits the current signal to the PLC controller, the PLC controller is in signal connection with the display, the PLC controller sends a signal to the display, and the graph formed by the photosensitive sensor covered by the palm is displayed on the display. The placing positions of the palm and the fingers are observed, so that the posture accuracy of the palm is improved continuously.

In order to improve the reality during training, a sternum model 5 is arranged in the manikin, and the middle lower part of the sternum model is contacted with a pressing plate. During operation, not only is the pressing position required to be accurate, but also the pressing frequency and the pressing force within one minute are ensured to meet the requirements. As shown in fig. 10 and 11, a counting mechanism is arranged between the pressing plate and the bottom plate, the counting mechanism comprises a pressing rod 6 fixed at the bottom of the pressing plate, a base 7 fixed at the top of the bottom plate, a travel switch 71 arranged inside the base, an ejector rod 82 connected with the base in a vertical sliding manner, a moving block 8 fixed at the top of the ejector rod, and a lifting spring 83 arranged between the moving block and the base, a groove 81 is arranged at the top of the moving block, the groove is hemispherical, the bottom of the pressing rod is also hemispherical and extends into the groove, and a gap is formed between the bottom of the pressing rod and the inner wall of the groove in a natural state. When the pressing plate moves downwards, the pressing rod moves downwards until the pressing rod is in contact with the inner wall of the groove and then extrudes the moving block, the moving block moves downwards under the guiding action of the ejector rod after being extruded until the ejector rod is in contact with the travel switch, the travel switch is in signal connection with the PLC, the PLC is connected with the counter, and the pressing plate moves downwards once when the ejector rod is in contact with the travel switch, namely, a trainer performs a cardiac resuscitation action, and the counter counts once. And counting for one minute, and displaying the counting times of the counter on the display, thereby being convenient for knowing whether the pressing frequency of the trainer meets the requirement or not. Meanwhile, the distance for the pressing plate to move downwards when the trainer presses the pressing plate is in accordance with a certain requirement, namely the pressing plate moves downwards by 5-6 cm. When the pressing depth is less than 5cm, the ejector rod cannot be in contact with the travel switch when the movable block is pushed to move downwards by the pressing rod, and counting cannot be achieved at the moment. When the pressing frequency of the trainer is small or the pressing depth does not meet the requirement for multiple times, the counter value is seriously smaller than the standard value. When the pressing frequency of the trainer is larger, the counter counts seriously larger than the standard value. When the counter count is equal to the norm value or within a reasonable range (the counter count is at 100-.

The utility model provides a intracardiac branch of academic or vocational study heart resuscitation trainer when pressing the position inaccurate, press the intensity and can not reach, press the frequency too big or the undersize, can all detect out, and then show on the display, and then help the training person to know the operation level of oneself, and then be convenient for improve.
