Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
Before the detailed structural description of the present device, it is necessary to understand the normal emergency operation of food poisoning. When people are found to have food poisoning, the first understanding of what the patient has eaten is needed, and after the first understanding of what the patient has eaten, a specific food poisoning emergency treatment method can be made according to the corresponding situation.
When the influence of the patient on the patient is not great after food poisoning, namely the patient can have self-consciousness, the patient firstly performs intragastric administration according to the food eaten by the patient, for example, the patient food poisoning is caused by eating more acidic substances or mistakenly taking acidic drugs, the intragastric administration treatment of protein liquid can be performed, and then the damage of acidic corrosion to the esophagus when the patient is directly vomited is avoided. When a patient eats toxic substances to cause a spastic reaction of the stomach, the patient can choose to firstly fill normal saline into the stomach, dilute food causing toxic spasticity of the stomach and then carry out emetic operation, so that the stomach food is easier to be spitted by the patient when the subsequent emetic operation is carried out.
When the patient has serious influence after food poisoning, the patient cannot effectively swallow himself at the moment, and during the gastric lavage operation, the gastric tube needs to be properly inserted into the stomach of the patient, and after a proper diluent or a neutralizing liquid is filled in the gastric tube, the subsequent emetic operation is performed. In the emetic method, the first-aid staff is required to master the proper body position and then perform emetic operation on the patient, so that the phenomenon that the vomit is inhaled into the respiratory tract when the patient vomits is avoided, and the normal breathing of the patient is influenced.
Based on the above-mentioned cautions when performing first aid on the food poisoning patient, the specific structure of the device will be described specifically:
the education training device after food poisoning comprises a human body model 1, a digestive tract model 2 and a nasopharyngeal part model 3, wherein the digestive tract model 2 is connected with the nasopharyngeal part model 3 and is arranged inside the human body model 1; a hydraulic sensor 4 is arranged in a stomach model 7 of the digestive tract model 2, and the hydraulic sensor 4 is connected with a control system arranged on the human body model 1; when the device is used, liquid or liquid-solid mixture is filled into the stomach model 7, so that the stomach condition of a patient suffering from food poisoning is simulated, and the hydraulic sensor 4 of the device is used as a detection element to detect the liquid volume in the stomach model 7 and transmit the detection information to a control system; the hydraulic sensor 4 can transmit the liquid pressure value of the stomach to the control system in real time, the stomach needs to be subjected to gastric lavage and emetic operation under normal conditions, so the induction value of the hydraulic sensor 4 can be subjected to the condition of increasing from a steady value to a reduction value, and the value of the hydraulic sensor 4 after the rescue of the food poisoning patient is completed under normal conditions can be smaller than the initial value of the hydraulic sensor 4, so the control system monitors the change of the pressure value of the hydraulic sensor 4 in real time, namely, whether the operation steps are correct or not can be judged when a trainer carries out certain operation, whether the toxic food in the stomach of the food poisoning patient is timely diluted and emetic or not within reasonable time, and then whether the trainer finally masters the emergency operation of the food poisoning patient is judged.
Because this device is the first aid operation of simulation food poisoning patient, the operation that consequently this device suggestion trainer need carry out for control system prompts to transmit and give alarm component 18 and express, alarm component 18 suggestion trainer is in the coma state or has the state of self-consciousness promptly, and then corresponds the different operations of following different patient states, thereby avoids appearing the phenomenon that the training is confused of trainer. The alarm assembly 18 is connected with the control system, and the control system transmits the received information to the alarm assembly 18 so that the alarm assembly 18 gives a prompt to a trainer; the control system arranged in the device is a PLC centralized control system and is used for carrying out data analysis on the circuit elements arranged in the device and transmitting the data to the alarm component 18 for expression; meanwhile, when the training operation is started, the alarm component 18 can prompt the trainer to carry out the emergency operation steps when the trainer is poisoned, so that the phenomenon of operation confusion of the trainer is avoided. The alarm component 18 of the device can select an alarm lamp as the alarm component 18, and in order to realize the intelligent level of the device, the alarm component 18 can select a liquid crystal digital display screen, so that the data information expressed by the control system is more convenient for a trainer to identify.
In order to restore the most real simulation training effect, the manikin 1 selected by the device, the digestive tract model 2 and the nasopharyngeal part model 3 arranged in the manikin 1 are both prepared by selecting silica gel materials, and the joint skeleton in the manikin 1 is prepared by selecting normal hard materials, which is a necessary condition for the real manikin 1, and the following explanation is not repeated.
When a patient suffering from food poisoning is subjected to emergency treatment, the gastric lavage operation is firstly carried out according to the condition of the patient, and the following specific settings are provided for the gastric lavage simulation component:
when carrying out the simulation operation of gavage, need carry out the gavage operation according to the different situations of patient food poisoning under the normal condition, following is the concrete structure setting when carrying out the gavage operation under two kinds of different situations:
1. when a patient suffering from food poisoning is in a self-perception state and can perform self-swallowing action, and when swallowing action of diluent or neutralizing liquid before emetic operation can be performed at the moment, specific structural setting is performed on the manikin 1, namely:
the gastric perfusion simulation assembly is arranged inside the human body model 1 and is connected with the control system. The oral cavity model 12 of the human body model 1 is connected with the digestive tract model 2 through the nasopharynx part model 3; the gastric perfusion simulation assembly comprises a pressure sensor 11, and the pressure sensor 11 is arranged at the back of the neck in the manikin 1; in this case, it is necessary for the patient suffering from food poisoning to swallow the diluent or neutralizing solution into the stomach as quickly as possible, thereby facilitating the subsequent emetic operation. In order to swallow the liquid to the stomach more easily for the patient suffering from food poisoning, the pressure sensor 11 is arranged at the back of the neck of the manikin 1, because under normal conditions, the person who swallows normally and is weak needs to help the patient suffering from food poisoning actively to swallow the liquid by a rescue worker, and when the patient is dragged to the neck of the patient in a lying state to lift the head upwards, the stretching degree of the esophagus of the patient reaches the maximum, and the swallowing operation of the liquid is more conveniently carried out. When the position behind the neck of the patient is reasonably supported, the effect can be achieved, and therefore the pressure sensor 11 can enable the trainer to master the position of normally supporting the head of the patient, and the effect of optimizing the gastric lavage operation is achieved.
2. When the patient of food poisoning is in the condition that does not have self-perception, it is relatively difficult that the patient carries out the swallowing operation of oneself this moment, consequently need carry out the intubate to the patient of food poisoning and irritate the medicine operation, the concrete structure setting that sets up on manikin 1 is as follows:
when the medicine irrigation operation is performed after the stomach tube insertion operation, the proper body position of the human body model 1 needs to be adjusted, and the stomach tube is inserted into the position of the stomach model 7 of the human body model 1 at a proper angle, so that the stomach tube is inserted into the stomach of a patient under the condition that the body of the patient suffering from food poisoning is not damaged, and the stomach irrigation operation of diluent or neutralizing liquid is performed through the stomach tube. In the normal gastric tube inserting step, the gastric tube is inserted from the nasal cavity of the patient, enters the esophagus through the throat part and is communicated with the stomach, and the stomach of the patient is perfused from the gastric tube after the gastric tube is communicated, so that the gastric lavage operation is realized. Because when the unconscious food poisoning patient carries out the stomach tube and inserts, its feedback that brings for the rescuer can be not enough, consequently need the trainer to master patient's position state and the inserting mode when the stomach tube inserts, just can correctly insert the stomach tube to patient's stomach.
The gastric perfusion simulation assembly comprises a first contact sensor 5, the contact sensor is arranged at the joint of the nasopharynx part model 3 and the alimentary canal model 2, and a displacement sensor 6 is arranged on the human body model 1 outside the joint of the nasopharynx part model 3 and the alimentary canal model 2; the first contact sensor 5 is arranged to detect whether the trainee correctly accesses the alimentary canal model 2 from the nasopharyngeal part model 3 when inserting the gastric tube from the nostril position of the nasopharyngeal part model 3, and when the first contact sensor 5 senses contact information, the trainee is proved to effectively access the gastric tube into the alimentary canal model 2 when inserting the gastric tube. Under the normal condition, in order to make the stomach tube more light insert to the stomach, consequently need be when inserting the stomach tube near chest position with patient's chin position for the stomach tube inserts to the esophagus along the nasal cavity back wall, consequently this device is provided with displacement sensor 6 on manikin 1 in the nasopharynx portion model 3 and the alimentary canal model 2 junction outside, when carrying out the plug-in operation of stomach tube with the detection training person, whether hug closely chest position with manikin 1's head model chin position. Simultaneously when setting up nasopharynx portion model 3 and alimentary canal model 2, set up both to when only displacement sensor 6's response value reaches the biggest, head model chin position hugs closely the chest position promptly, head model is whole to be rotated the chest position that makes the chin position be close to manikin 1 promptly, just can make nasopharynx portion model 3's nasal cavity passageway and alimentary canal model 2's esophagus model 8 be linked together, make the stomach tube touch first contact inductor 5 and sense the signal, and then prove that the training person is correct to insert the stomach tube to esophagus model 8 inside.
A second contact sensor 9 is arranged at the joint of the stomach model 7 and the esophagus model 8 of the digestive tract model 2, and an electric tightening piece 10 is arranged outside the esophagus model 8 at the upper end of the second contact sensor 9. The second contact sensor 9 that sets up here in the esophagus model 8 junction of stomach model 7 and alimentary canal model 2 is for, whether detect the stomach tube normally enter into stomach model 7 inside, and the obstacle that hinders the stomach tube to enter into the stomach under normal condition is that the cardia position that the stomach is connected with the esophagus comprises the cardia muscle crowd that can contract, consequently the electronic shrink piece that sets up in this device is used for simulating cardia muscle crowd, carries out contracting and hinders stretching into of stomach tube, only can stretch into stomach tube to stomach model 7 inside when passing through electronic shrink piece. The electric contraction part arranged in the device can be selected as an electric clamp arranged on the outer side of the joint of the stomach model 7 and the esophagus model 8 to clamp and contract the esophagus model 8 at the joint, and other electric telescopic structures can be selected to realize the electric contraction part.
The device simulates the arrangement of the gastric perfusion component for the emergency treatment of a patient suffering from food poisoning, and the gastric perfusion operation is to spit out toxic substances in the stomach, so the following specific structural arrangement of the emetic component of the device under different conditions is as follows:
here, the emetic simulation module provided on the manikin 1 is a method for simulating emergency treatment of a patient suffering from food poisoning in different situations, and therefore the following settings are made in the present apparatus:
1. when the patient is conscious of himself, the emetic simulation unit provided in the phantom 1 of the present apparatus at this time is as follows:
the vomit-promoting simulation component is arranged inside the human body model 1 and is connected with the control system; the emetic simulation assembly comprises a contact switch 13 and a squeezing device 14 connected with the contact switch 13, wherein the contact switch 13 is arranged at the throat part of the nasopharynx part model 3, and the squeezing device 14 is arranged at the outer side of the stomach model 7 to squeeze the stomach model 7. Because the method for stimulating the patient suffering from food poisoning to vomit normally stimulates the throat part of the patient, so that the throat part feels stimulation to drive the stomach muscle to contract, the contact switch 13 is arranged at the throat part of the nasopharynx part model 3 in the device, and only when the throat part of the nasopharynx part model 3 is correctly stimulated, the contact switch 13 can transmit a switch signal to the extruding device 14 to extrude the stomach model 7, so that the mixture in the stomach model 7 is extruded. The squeezing device 14 comprises an electric telescopic rod 16 and a pressing push plate 17, wherein the electric telescopic rod 16 is fixedly arranged on the outer side of the stomach model 7 in the human body model 1 and is connected with the pressing push plate 17; the electric telescopic rod 16 stretches and retracts to drive the pressing push plate 17 to move, so that the stomach model 7 is extruded, and then the mixture in the stomach model 7 is extruded out of the stomach model 7.
It should be noted here that the contact switch 13 is different from the first contact sensor 5 provided above, in the manikin 1, the device for controlling the squeezing of the stomach model 7 by the external squeezing device 14 of the stomach model 7 is the contact switch 13, and the position for physiologically stimulating the throat to generate vomiting response is the junction of the oral cavity and the throat part, i.e. the front end part of the nasopharynx part model 3 of the device; the physiological joint of the nasal cavity and the throat part is the rear end part of the throat part, namely the rear end position of the nasopharynx part model 3 of the device, which is why the whole head of a human body needs to be rotated to enable the lower jaw part to be tightly attached to the chest when the stomach tube is inserted through the nasal cavity. Therefore, the contact switch 13 and the first contact sensor 5 arranged above cannot influence each other in the arrangement position, and the premise is that when the human body model 1 is operated to be inserted into the stomach tube, the lower jaw part of the human body model 1 needs to be tightly attached to the chest position of the human body model 1, otherwise, the stomach tube entering from the nasal cavity of the nasopharynx part model 3 can touch the contact switch 13 to extrude the stomach by the extruding device 14, and further, the training failure of a trainer is judged. When a patient suffering from food poisoning is rescued, the patient needs to lie down when inserting the gastric tube, and specific vomiting is generated at the time, so that food in the stomach of the patient is easily choked into the trachea, and normal breathing of the patient is affected. Thus:
a pressure sensing plate 15 is arranged on the outer side of the left chest of the human body model 1, and the pressure sensing plate 15 is connected with a control system; since the best emetic method for the person in emetic is to tilt the body of the patient to the left, the pressure sensing plate 15 is arranged on the outer side of the left chest cavity of the manikin 1, and further, whether the trainer correctly tilts the manikin 1 to the left when the trainer emetic the food poisoning patient, even if the pressure sensing plate 15 on the outer side of the left chest cavity of the manikin 1 senses the pressure, the trainer further judges whether the operation is correct.
2. When the patient is in a coma, the setup of the emetic-simulating assembly on the manikin 1 is as follows:
when the condition that the stomach tube is not inserted is not provided, but the vomit operation of a patient suffering from food poisoning is required, the mannequin 1 is required to be provided with a pressure sensing plate 15 on the outer side of the left chest cavity of the mannequin 1, and the pressure sensing plate 15 is connected with a control system; the reason for this is as described above and will not be explained here too much.
Different from the situation of emetic under the normal condition, the lower jaw model of the manikin 1 is hinged with the head model, and the hinged part is provided with the torsion spring, so that the lower jaw model and the head model are in a closed state under the action of the torsion spring, and a trainer can control the extrusion device 14 to extrude the stomach model 7 only by opening the lower model manually and touching the contact switch 13, but still needs to enable the pressure sensing plate 15 to sense a pressure signal at first to ensure the correct operation of the trainer.
The use method of the education training device after food poisoning comprises the following steps:
s1, the control personnel control the control system to select the poisoning condition of the food poisoning patient, and transmit the expression information to the alarm component 18, the trainer observes the information given by the alarm component 18, and the food poisoning emergency training operation is carried out;

s3, when the alarm component 18 indicates that the first-aid operation information is food poisoning first-aid operation with self-perception, the trainer pushes the pressure sensor 11 at the back of the neck in the manikin 1, so that the pressure sensor 11 senses a pressure signal and transmits the pressure signal to the control system, the head model of the manikin 1 is lifted, the simulated liquid is filled into the stomach model 7, and the pressure value of the hydraulic sensor 4 is increased;
inclining the human body model 1 to the left, enabling a pressure sensing plate 15 on the outer side of the chest cavity of the human body model 1 to sense a pressure value, then stimulating a contact switch 13 arranged at the throat part of the nasopharynx part model 3 by using a pressant, enabling the contact switch 13 to control an extrusion device 14 on the outer side of the stomach model 7 to extrude the stomach model 7, enabling liquid or a liquid-solid mixture in the stomach model 7 to be discharged out of the human body model 1, and finally reducing the pressure value of the hydraulic sensor 4;
s4, when the alarm component 18 indicates that the first-aid operation information is a coma food poisoning first-aid operation, the trainer rotates the head model of the manikin 1, and enables the displacement sensor 6 to sense the displacement distance of the head model, the displacement information is transmitted to the centralized control system, after the trainer inserts the simulation pipeline into the nasal cavity of the nasopharynx portion model 3 and passes through the first contact sensor and the second contact sensor 9 in sequence, the first contact sensor and the second contact sensor 9 transmit the information to the control system, the simulation liquid is filled into the stomach model 7 through the simulation pipeline, and the pressure value of the hydraulic sensor 4 is increased;
the simulated liquid in the stomach model 7 is pumped out by using a simulated pipeline, so that the liquid or the liquid-solid mixture in the stomach model 7 is discharged out of the human body model 1, and finally, the pressure value of the hydraulic sensor 4 is reduced;
and S5, the control system monitors the sensing information of each sensing element when the trainer performs S3 and S4 in real time, processes the sensing information and transmits the processed sensing information to the alarm assembly 18 to judge whether the operation of the trainer is correct.
