ELECTRONIC STANDARDIZED HUMAN MODEL SYSTEM FOR FIRST AID TRAINING AND EXAMINATION

TECHNICAL FIELD The invention relates to the technical field of models for medical teaching, and in particularly to an electronic standardized human model system for first aid training and examination.

BACKGROUND The qualification examination for practicing doctors and the qualification examination for assistant practicing doctors are the examinations to evaluate whether the applicants have the professional knowledge and skills necessary for practicing. The nature of the qualification examination for doctors is the standard reference examination for industry access. When the state organizes the examination of medical practitioners, it is necessary to recruit volunteers, train volunteers, and imitate various patients to be used as examination props. After training, this volunteer becomes a simulated patient, or Standardized Patients (SP for short). However, standardized patients need to recruit, train and imitate patients on the spot, which costs a lot of manpower, material resources and financial resources. However, SP can't imitate many positive signs, so it can't well assess doctors’ clinical judgment and practical ability. With the development of economy and technology, there are many simulated medical teaching products on the market, such as fundus examination model, chest and abdomen auscultation model, percussion model, palpation model, breast examination model, intravenous injection model, puncture model, etc. These models can replace SP patients for real on-site operation, and at the same time, they can simulate different positive signs, which makes the patient's signs at the examination site irregular, and can better assess doctors' judgment ability of on-site operation. However, the functions involved in these models are single, and many models are often needed to participate in the examination. These models do not reflect the characteristics of the whole person. Modular examination makes the scene chaotic, occupying a large area, making it difficult to arrange the examination and store it after completion, and the examination data and results cannot be integrated on the same report card.

DESCRIPTION OF THE INVENTION The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, but not all of them. Based on the embodiment of the invention, all other embodiments obtained by ordinary technicians in the field without creative labor belong to the scope of protection of the present invention.

The invention provides an electronic standardized human model system for first aid training and assessment, wherein the human model is made of environment-friendly and pollution-free polymer material. The system specifically includes the following steps: (1) Anatomical markers, OLED simulated eyeballs and simulated carotid arteries are arranged on the human model, and the simulated eyeballs and simulated carotid arteries are driven by the control terminal and change with the state change of the human model. Among them, the anatomical landmarks include nipple anatomical landmarks, rib anatomical landmarks, sternum anatomical landmarks, xiphoid anatomical landmarks and head and neck anatomical landmarks. Each anatomical landmark is obvious, the anatomical position of the head and neck is accurate, and the head can swing left and right or rotate horizontally for 180 degrees, which is convenient to remove foreign bodies in oral cavity. The OLED simulated eyeball comprisesld)502492 retina, a pupil and a transparent crystal, and the control terminal changes the states of the retina, the pupil and the transparent crystal with the state change of the human model. Specifically, the pupil can reflect light at any angle, and the reflection state of the pupil will automatically change with the change of the illness. When the human model is dead, the pupil will be dilated and the reflection of light will disappear. The simulated carotid artery is used for simulating arterial pulsation, and the control terminal adjusts the pulsation intensity of the simulated carotid artery with the change of the state of the human model. Candidates can touch the carotid pulse. When the human model is dead, the simulated carotid pulse intensity is zero. Preferably, the carotid pulse intensity has force feedback, which means that the greater the pressure, the stronger the pulse beat, which can monitor whether the candidates have checked the pulse.

(2) The human model is provided with a cardio-pulmonary resuscitation module wirelessly connected with the control terminal, and the cardio-pulmonary resuscitation module is provided with a training mode and an examination mode. Wherein, the control terminal is wirelessly connected with the cardio-pulmonary resuscitation module through Bluetooth. Specifically, the control terminal monitors the pressing times, pressing position, pressing depth, pressing frequency and pressing rebound of the cardio-pulmonary resuscitation module, and realizes the pressing interruption time; The control terminal also monitors the blowing times, tidal volume, tidal time and the amount of gas entering the stomach of the cardio-pulmonary resuscitation module. In the training mode, the control terminal monitors the pressing depth, pressing frequency, blowing times, tidal volume, tidal time and gastric intake gas volume, and displays them on the display device; in the examination mode, the examiner can customize the parameters monitored by the control terminal according to the examination requirements, and can also set the time limit for completing the operation and count the accuracy rate.

(3) A defibrillation module connected with the control terminal is arranged on the human model, and the defibrillation module is used for absorbing and detecting electric energy. Preferably, the defibrillation module absorbs electric energy through the electrode sheet 10, as shown in Fig. 1. The defibrillation module is used in conjunction with the defibrillator. After the defibrillator is used to defibrillation the human model, the electric energy emitted by the defibrillator is absorbed by the defibrillation module, thus avoiding the harm of the electric energy to the operator and measuring the electric energy. The electric energy measured by thé/502492 human body model can be compared with the electric energy required by the examination to judge whether the electric shock operation is in place; the human body model can also be defibrillated by analog defibrillator, and the energy can be displayed during defibrillation.

(4) An arm puncture module connected with the control terminal is arranged on the human model, and the puncture module comprises a vein puncture module and an artery puncture module, and simulated blood vessels are arranged in both the vein puncture module and the artery puncture module. One arm is a venipuncture module, which can be used for intravenous infusion, and the other arm is an arterial puncture module, which can be used for arterial blood collection. The arm has a built-in simulated blood vessel, which can be filled with simulated blood. Under the condition of external blood circulation pump, the internal blood can flow and circulate, and there is a certain pressure in the blood vessel. After puncture, blood return can be seen. During puncture, the wall of the blood vessel has a certain elasticity, and there is a breakthrough in needle insertion. Arterial puncture and blood collection can be performed by the left arterial arm. As shown in Fig. 2, the arm 20 is provided with a simulated pulse 21, a simulated blood vessel 22, a tourniquet binding detection circuit board 23, a blood circulation circuit board 24 and a simulated blood injection port 25.

(5) The human model is provided with an abdominal puncture module connected with the control terminal, and the abdominal puncture module is used for judging whether abdominal puncture is correct. Specifically, when the abdominal puncture is wrong, it can give an alarm, and if the puncture is successful, it can penetrate the simulated peritoneal effusion, which can be connected with an external display device to display the puncture judgment result. When puncturing, medical positioning is carried out according to the signs on the body surface. If puncturing is correct in the correct range, simulated peritoneal effusion can be extracted. If puncturing is not correct, an error will be prompted, which may damage the inferior epigastric artery or puncture the internal organs.

(6) The human model is provided with a lower limb module connected with the control terminal, and the lower limb module is provided with an open wound for simulating bleede. As shown in Fig. 3, the lower limb 30 is provided with a plurality of open wounds 31, which can béJ502492 wounds, fractures, burns, knife wounds, etc, which can simulate bleeding, stop bleeding when the femoral artery is tied tightly, and can be used for transporting limb fractures.
