[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] like Figures 1 to 5 As shown, an embodiment of the present invention provides a human upper limb simulation device for simulating medical care, including: a face model 1, a nasogastric feeding tube 2, a nosebleed duct component 3, a digestive tract component 9 and a chest cavity model 4.

[0034] The face model 1 has a nasal cavity 14 , and the nasal cavity 14 has seven easy bleeding points 5 . The nose bleeding duct components 3 are connected to the seven easy bleeding points 5 respectively.

[0035] Specifically, Figure 1 As shown, the doctor can simulate the insertion of the nosebleed duct assembly 3 into the face model 1 and into the positions of seven bleeding spots 5, so as to explain, illustrate and demonstrate to the patient and his family, which can reduce the patient's anxiety and restlessness.

[0036] The digestive tract component 9 has an oral cavity 91, a pharyngeal cavity, a laryngeal cavity, an esophagus 92 and a stomach 93. The nasogastric tube 2 is inserted through the nasal cavity 14 of the face model 1 and reaches the stomach 93 through the pharyngeal cavity, the laryngeal cavity and the esophagus 92.

[0037] Esophageal foreign bodies are a common clinical emergency, which refers to foreign bodies (such as fish bones, bones, toys, dentures, etc.) that are temporarily lodged or stuck in the esophagus due to various reasons. 92 Esophageal foreign bodies can occur at any age, but are more common in children and the elderly.

[0038] When the foreign body is small or blunt, swallowing pain is not obvious or only obstruction is felt; when the foreign body is sharp or secondary infection occurs, swallowing pain is usually more severe. When the foreign body is stuck in the upper part of the esophagus, the pain is usually at the base of the neck or the suprasternal fossa; when the foreign body is located in the middle part of the esophagus, there is often pain behind the sternum, which is reflected to the shoulder and back.

[0039] If the foreign body is large, it may press forward on the posterior wall of the trachea 43; or if the foreign body is located high and part of it does not enter the esophagus 92 but presses on the larynx, breathing difficulties may occur, especially in young children, who may suffocate to death.

[0040] Therefore, the doctor can explain the blockage of the esophagus by the foreign body 101 through the esophagus 92 so that the patient and family members can understand the blockage of the esophagus by the foreign body 101, and the doctor can adjust the position of the foreign body in the esophagus 92 according to the patient's condition.

[0041] The chest cavity model 4 has an anterior cervical tracheotomy stoma 41, a tracheal cannula 42, a cannula core, an open gauze, a trachea 43, a bronchus 44 and a lung 45. The trachea 43 is respectively connected to the face model 1, the bronchus 44 and the lung 45. The tracheal cannula 42 and the cannula core combination are inserted into the trachea 43 through the anterior cervical tracheotomy stoma 41, and fixed to the neck of the model with a cotton rope, and the tracheal cannula 42 is separated from the skin around the anterior cervical tracheotomy stoma 41 by padding with an open gauze.

[0042] It should be noted that foreign bodies blocking the trachea refer to foreign bodies located below the glottis, in the trachea 43 and in the bronchus 44. When foreign bodies pass through the glottis and enter the trachea 43, there will be breath holding and severe coughing. If the foreign body is stuck in the glottis, extreme breathing difficulties or even death from suffocation may occur; if the foreign body enters deeper into the bronchus 44, there may be no obvious clinical symptoms except for a slight cough or breath holding. After being inhaled, the foreign body may stay somewhere in the bronchus 44, at which time there may be no symptoms or only a slight cough. The length of this period varies, depending on the nature of the foreign body and the degree of infection.

[0043] Therefore, the doctor can explain the blockage of the trachea by the foreign body 102 through the trachea 43 and the bronchus 44 so that the patient and family members can understand the blockage of the trachea by the foreign body 102, and the doctor can adjust the position of the foreign body to any position of the trachea 43 and the bronchus 44 according to the patient's condition.

[0044] like Figure 2 As shown, for patients who cannot eat orally, the doctor inserts the nasogastric tube 2 through the nostrils, passes through the pharyngeal cavity, the laryngeal cavity, and reaches the stomach 93 through the esophagus 92, and pumps water and food into the patient's nasogastric tube 2 and stomach through the manual pressurized syringe push rod and piston to ensure that the patient takes in enough nutrition, water and medicine. The process of inserting the nasogastric tube 2 into the stomach 93 can then be demonstrated and explained to the patient and his family members, and the patient and his family members can also manually operate the nasogastric tube, learn nasogastric feeding operations and nursing operations, and thus understand the process of nasogastric feeding and nursing, and at the same time learn the importance of nasogastric feeding and nursing.

[0045] like Figure 4 As shown, it is a structural diagram simulating esophageal foreign body obstruction. For patients with foreign bodies stuck in the esophagus, the doctor adjusts the esophageal foreign body 101 to a specific position of the esophagus 92, which is basically consistent with the patient's condition. The doctor clearly and vividly explains the patient's condition, treatment plan, prognosis and precautions to the patient and his family.

[0046] like Figure 5 As shown, it is a structural diagram simulating the blockage of tracheal foreign bodies. For patients with foreign bodies entering the airway, the doctor adjusts the tracheal foreign body 102 to a specific position of the trachea 43 and bronchus 44, which is basically the same position as the patient's condition. The doctor explains the patient's condition, treatment plan, prognosis and precautions to the patient and his family clearly and vividly.

[0047] like Figure 3 As shown, after the tracheotomy, the tracheal tube 42 is connected to the trachea 43 to solve the problem of dyspnea caused by laryngeal dyspnea, respiratory dysfunction or lower respiratory tract secretion retention. Postoperative care for tracheotomy is very important. The patient needs to maintain a proper posture, keep the airway open, and prevent infection and dyspnea. The patient needs to observe the breathing condition, ensure that the airway is open, avoid secretion blockage, and perform sputum suction, change gauze, and clean the tube core.

[0048] Doctors can teach the operation of suctioning sputum and cleaning the tube sleeve core of the tracheal tube 42 on the chest model 4, so that patients and their families can clearly understand the specific operations, and through practical operations and repeated learning, they can become familiar with the specific post-tracheotomy care.

[0049] The present invention sets seven easy-to-bleed spots 5 in the nasal cavity 14 of the face model 1, and the nosebleed duct assembly 3 is respectively connected to the seven easy-to-bleed spots 5; and the nasogastric tube 2 is inserted through the nasal cavity 14 of the face model 1, through the pharyngeal cavity and the laryngeal cavity, and reaches the stomach 93 through the esophagus 92; the trachea 43 is respectively connected with the face model 1, the bronchus 44 and the lungs, and the tracheal cannula 42 is inserted into the trachea 43 through the anterior cervical tracheotomy stoma 41, and is fixed to the neck of the model with a cotton rope, and the tracheal cannula 42 is separated from the skin around the anterior cervical tracheotomy stoma 41 by an open gauze. The present invention can clearly simulate various states of nasal bleeding, the feeding process through a nasogastric tube 2, the position of esophageal foreign body blockage, the position of tracheal foreign body blockage, and the state after tracheotomy 43, and the doctor teaches the patient and his family on site, so that the patient and his family can actually operate and learn repeatedly, which is helpful for the patient and his family to understand the disease. The mastery of postoperative nursing skills can avoid a series of malignant events caused by poor postoperative care, which is helpful for the patient's postoperative recovery and improves the patient's quality of life. At the same time, it can greatly enhance the confidence of patients and their families in fighting the disease and help improve the doctor-patient relationship. It is of great significance for improving the health literacy of patients and their families, preventing diseases, improving medical experience, reducing medical costs, and promoting a healthy lifestyle.

[0050] In the human upper limb simulation device for simulating medical care of the present invention, as Figures 1 to 5 As shown, the facial model 1 includes a left half face 11, a right half face 12 and a rotation axis 13, and the left half face 11 and the right half face 12 have a left half nasal cavity portion 15 and a right half nasal cavity portion 16 respectively, and the rotation axis 13 is arranged between the left half face 11 and the right half face 12, and is used to drive the left half face 11 and the right half face 12 to rotate.

[0051] The present invention sets the rotating shaft 13 between the left half face 11 and the right half face 12, so that the left half face 11 and the right half face 12 can be driven to rotate by the rotating shaft 13 to separate the left half face 11 and the right half face 12, thereby further facilitating the observation of the patient and the family members and the operation and understanding of the patient and the family members.

[0052] In one embodiment of the human upper limb simulation device for simulating medical care of the present invention, Figure 1 As shown, the seven bleeding spots 5 include mucosal erosion in the Li's area, vascular stumps in the Li's area, vascular stumps in the olfactory fissure area, vascular stumps in the posterior fornix of the inferior nasal meatus, middle nasal meatus area, nasopharynx and nasal sinus tumors.

[0053] Mucosal erosions in the Li's area, vascular stumps in the Li's area, and vascular stumps in the olfactory fissure area are located on the left half of the face 11, and vascular stumps in the posterior fornix of the inferior meatus, middle meatus area, nasopharynx, and nasal sinus tumors are located on the right half of the face 12.

[0054] Specifically, Figure 1 As shown, the specific locations of mucosal erosions in the Li's area, vascular stumps in the Li's area, vascular stumps in the olfactory fissure area, vascular stumps in the posterior fornix of the inferior meatus, middle meatus area, nasopharynx, and nasal sinus tumors.

[0055] When inserting the nosebleed duct assembly 3 into the seven bleeding spots 5, the doctor can divide the left half face 11 and the right half face 12 into two by rotating the shaft 13, and insert the nosebleed duct assembly 3 into the mucosal erosion in the Li's area, the vascular stump in the Li's area, and the vascular stump in the olfactory fissure area of ​​the left half nasal cavity 15 on the left half face 11, and into the vascular stump in the posterior fornix of the inferior nasal meatus, the middle nasal meatus area, the nasopharynx, and the nasal sinus tumors of the right half nasal cavity 16 on the right half face 12, thereby being able to demonstrate the insertion process of the nosebleed duct assembly 3 more clearly.

[0056] In one embodiment of the human upper limb simulation device for simulating medical care of the present invention, Figure 1 As shown, in order to further demonstrate the insertion of the nosebleed duct assembly 3, the nosebleed duct assembly 3 includes seven rubber tubes, and the seven rubber tubes are inserted into the left half nasal cavity 15 and the right half nasal cavity 16 from the top of the left half face 11 and the right half face 12 respectively, until they correspond to the seven bleeding points 5.

[0057] In one embodiment of the human upper limb simulation device for simulating medical care of the present invention, in order to improve the convenience and ease of insertion of the rubber tube, the hardness of the rubber tube is greater than the hardness of the left half face 11 and the right half face 12, so that the rubber tube can be quickly inserted into the left half face 11 and the right half face 12 when subjected to the force of the doctor.

[0060] Specifically, the esophagus 92 is buried inside the neck model 6 .

[0061] When demonstrating the insertion of the nasogastric tube 2 into the stomach 93 , the doctor inserts the nasogastric tube 2 into the esophagus through the oral cavity 91 or the nostril, and then passes through the pharynx and the laryngeal cavity and through the esophagus 92 to reach the stomach 93 .

[0062] When performing the postoperative care demonstration for tracheotomy 43, the doctor teaches the suction of sputum from the tracheal tube 42 on the chest model 4 and the operation of the tracheal tube 42, and can also teach the operation of changing gauze, so that the patient and his family can clearly understand the specific operations, and become familiar with the specific postoperative care for tracheotomy 43 through actual operations and repeated learning.
