Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an advanced emergency treatment model for secondary rescue treatment training that can learn the operation of airway intubation and simulate an electrocardiogram waveform by a change in heart rate.
[0002]
[Prior art]
In the process of transporting a patient from the emergency site to a hospital, for example, a paramedic performs a first aid treatment, and the first aid includes a first life support performed without using an instrument and a second life support using an instrument. . The primary life-saving treatment includes treatments such as heart massage and artificial respiration, and the secondary life-saving treatment includes treatments such as defibrillation for arrhythmia, securing airways, securing venous tracts, and infusion of infusion. Several simulator products have already been developed and sold as simulators for learning this secondary lifesaving treatment.
For example, with regard to simulator products that train the operation of airway intubation, conventional ones always allow airway intubation because the airway is not obstructed, and for securing the airway, perform artificial respiration with a back mask. There is a danger that the trainee will learn the wrong technique because the air will enter even if the airway is not secured when the airway is opened. Currently, Japanese paramedics can use three types of equipment when securing the airway: a laryngeal mask, a closed esophageal airway, and a combination tube. The laryngeal mask does not intubate the throat, but it secures the airway by pressing the flat part of the laryngeal mask against the entrance of the throat to secure the airway for the patient who needs artificial respiration. By closing the esophagus with the tip cuff (balloon), air is supplied from the trachea through the side hole of the tube to ventilate the lungs, and the combitube has a double lumen structure (two cuffs). Therefore, it is possible to secure the esophagus and perform artificial respiration by properly using the lumen regardless of whether it is inserted into the esophagus or the trachea. In either case, a stethoscope is applied to the chest to check whether the airway is secured.However, in the conventional advanced emergency treatment simulator, an airbag that imitates the lungs without structural airway bronchial structure is used. There is a problem that it is not possible to check the ventilation state of each lung because of being one, and it is not possible to hear the ventilation sound so that the range of training is limited and effective training cannot be performed.
[0003]
Further, in the conventional simulator products, since the connection cord is provided between the electrocardiogram waveform simulator and the doll, it may hinder the trainee when performing the training of the second lifesaving treatment, or the leader may have the code. In some cases, training is performed while being careful not to disturb the trainee, and the efficiency and effectiveness of the training may be reduced. The contents of the ECG waveform simulator also have problems such as the fixed heart rate, the inability to mix the heart massage waveform, and the inability to obtain a pulse synchronized with the ECG. It is structured so that it is difficult to understand until now, and it is also difficult for teachers to teach.
[0004]
[Problems to be solved by the invention]
The present invention solves the above-mentioned problems, and conducts various studies on advanced rescue treatment models of secondary rescue treatment training that can surely acquire training of airway intubation and other emergency rescue treatment of secondary rescue including airway securing. As a result, the product of the present invention has been completed. The purpose of the product of the present invention is to provide an advanced emergency treatment model for secondary life support training in which a high effect of secondary life support training such as securing of an airway can be obtained. .
[0005]
[Means for Solving the Problems]
The gist of the present invention is an advanced emergency treatment model for secondary rescue treatment training in which the whole body is made of a flexible synthetic resin, wherein a fixing pin is provided on the head skeleton of the model, and along the fixing pin. A first arm having a bent portion slidable in one direction, and connecting a tip of the bent portion of the first arm to a second arm to which a tongue is attached, and lowering the head of the model, or lower jaw The first arm is slid by performing a raising operation, whereby the second arm is actuated, and the tongue that has blocked the airway opening is tilted forward to open the airway, and the opening is performed by mechanically expanding the airway. It is an advanced emergency treatment model for secondary life support training characterized by having a pharyngeal structure. Further, in this advanced emergency treatment model, an electronic circuit of a common carotid artery generator that is generated in synchronization with an electrocardiogram is provided in the body of the model. It is a treatment model. Further, it is preferable that the heart massage waveform be mixed with the electrocardiogram waveform in synchronization with the heart massage.
[0006]
By using this simulator, the state of the airway obstruction in the secondary life-saving treatment area is mechanically reproduced without using electricity, and the laryngoscope is used to avoid subsidence of the tongue, and the airway, pharynx, larynx, and nasal cavity Training of an intubation tube and a laryngeal mask can be performed, and furthermore, after opening the airway, it is possible to train an esophageal closed airway and a combination tube by opening the airway by mechanically expanding the airway.
In other words, as a rescue method, one palm is placed on the forehead, the other palm is placed on the nape near the back of the head, and the palm of the forehead is gently warped backward, and the head flexion neck lifting method that lifts the nape , Put one palm on the forehead, bend the head a little backward, hit the middle finger, the index finger of the other hand to the tip of the chin, lift the chin, lift the chin, and raise the chin In the first-aid method placed on the parietal side or beside the head, bring the fingers, except the thumbs of both hands, to the ascending ascending branch, and apply the thumbs to the lower jaw slightly below the corners of the mouth on each side. The lower jaw is lifted with both thumbs while the lower jaw is raised slightly with the fingers excluding the thumb, and the lower lip is pushed up slightly with both thumbs. There are laws, but corresponding to each of these first-aid Tube tube, training of Raringearumasuku, or esophagus closing airway, it is the training of the combination tube.
In addition, if necessary, the chest is provided with an airbag imitating the left and right lungs and an airbag imitating the stomach of the abdomen using a structure in which the bronchi are divided into right and left, and the air sent from the tube is used for the air. The airbag may be inflated, and a check of the ventilation state by a stethoscope (air supply sound) may be made so that the respective states of the left and right lungs can be confirmed. In addition, the swelling of the left and right lungs and the abdomen of the chest may be visually observed, the abdomen may be provided with a valve that is opened only when the esophagus is intubated, and the air supply sound of the abdominal stomach may be confirmed with a stethoscope from outside the epidermis.
With the above structure, it is possible to provide a simulator for whole-body secondary rescue treatment training that is effective for learning a technique.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail.
As described above, the training for secondary life support according to the present invention can be practiced using a laryngeal mask, an esophageal closed airway, and a two-way tube in addition to intubation in the airway. This advanced emergency model may be formed integrally with the whole body, or may be divided into a head, a torso, both hands, both feet and the like. The material is not particularly limited, but it is preferable to use a flexible synthetic resin such as a silicone resin or a vinyl chloride resin. In the secondary rescue treatment training model according to the present invention, the airway is constantly obstructed in the throat, and the tongue tilts forward and the airway opens due to the operation of lowering the head or raising the chin of the model. Is secured. Therefore, unlike the conventional model in which the airway is always open as in the conventional model, the operation of lowering the head or raising the chin causes the tongue to tilt to the front and open the airway to secure the intubation. Therefore, more practical training can be performed.
Furthermore, after opening the airway, the esophageal ostium can be mechanically pushed open to open, and training can be performed on the airway intubation tube, laryngeal mask, and the like.
