Description

Technical Field

[0002] Craniocerebral injury is a common trauma. Common causes of craniocerebral injury include traffic accidents, falls from heights, missteps, industrial accidents and firearm injuries. Occasionally, craniocerebral injury in infants is caused by dystocia and forceps. Qualified professional nurses must undergo years of professional theoretical study and clinical practice before they can be competent for their jobs. When learning professional nursing skills, nurses must first practice operations on a mannequin, thereby producing a simulated nursing teaching mannequin, such as a highly simulated multifunctional nursing teaching mannequin disclosed in CN201810254504.4, or a highly simulated multifunctional nursing teaching mannequin disclosed in CN201320038437.5, or a nursing skills practical training device disclosed in CN 202310225895.8.

[0003] However, the aforementioned nursing teaching human model cannot be used for craniocerebral injury teaching, and the existing craniocerebral teaching models are mostly used for craniocerebral anatomy, such as the teaching craniocerebral model device disclosed in CN202410275484.4, a craniocerebral model disclosed in CN201810609746.0, or a craniocerebral anatomy and imaging teaching model disclosed in CN202110239846.0, which cannot be used for craniocerebral injury teaching. Therefore, it is necessary to provide a craniocerebral injury simulation human teaching model. Summary of the invention

[0006] With the above technical solution, the operator can not only take care of brain injury through the craniocerebral simulation unit, but also take care of complications of brain injury through the urinary system simulation unit, the blood circulation system simulation unit, and the respiratory system simulation unit, which is more in line with the actual situation and is conducive to teaching.

[0019] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0020] The present invention provides a craniocerebral injury simulation human teaching model, such as Figure 1As shown, in a preferred embodiment, the teaching model includes a simulated human body with a simulated skin layer on the outer surface, and the simulated human body includes a head with five sense organs, a torso with a chest and abdomen, internal organs and reproductive organs, and limbs connected to the torso. Among them, the head has a cranial brain simulation unit 10 that simulates cerebral edema, cerebral hematoma, brain fracture, brain hernia, and cerebrospinal fluid leakage; the torso has a urinary system simulation unit 20, a blood circulation system simulation unit 30 and a respiratory system simulation unit 40, and the cranial brain simulation unit 10, the urinary system simulation unit 20, the blood circulation system simulation unit 30 and the respiratory system simulation unit 40 are connected to a controller (not shown in the figure).

[0021] The controller is preset with control programs for the urinary system simulation unit 20, the blood circulation system simulation unit 30, and the respiratory system simulation unit 40 corresponding to different brain injuries (specifically the aforementioned cerebral edema, cerebral hematoma, brain fracture, brain hernia, and cerebrospinal fluid leakage) (the control programs preset in the controller are prior art and will not be described in detail here); the operator selects different brain injuries and performs nursing operations on the brain injuries and the complications of the urinary system simulation unit 20, the blood circulation system simulation unit 30, and the respiratory system simulation unit 40.

[0022] With such a technical solution, by setting up the cranial brain simulation unit 10, the urinary system simulation unit 20, the blood circulation system simulation unit 30 and the respiratory system simulation unit 40, the operator selects a specific brain injury item through the operation page of the controller, and the controller controls the cranial brain simulation unit 10, the urinary system simulation unit 20, the blood circulation system simulation unit 30 and the respiratory system simulation unit 40 to work, so as to simulate brain injury and its complications, and the operator performs care. For example, when the intracranial pressure increases (specifically, it may be caused by cerebral edema, cerebral hematoma, cerebral hemorrhage, hydrocephalus and intracranial inflammation) and causes severe damage to the neurological function, urinary incontinence may be caused. When the cranial brain simulation unit 10 is used to care for the increased intracranial pressure, the urinary system simulation unit 20 can also be used to care for the resulting urinary incontinence complications.

The urethra tube 23 can be inflated, and specifically, the urethra tube 23 can be inflated by setting an air pump 25 (the valve 24 is closed during inflation), so that the water in the second water bag 22 cannot be discharged normally, which is used to simulate urine retention. When the urethra tube 23 is not inflated, the valve 24 is opened to discharge the water in the second water bag 22 from the urethra tube 23 to simulate urinary incontinence.

The airway model 42 is connected to the mouth and nose of the head, and the trainees can perform cardiopulmonary resuscitation care and sputum suction exercises through the respiratory system. The respiratory system simulation unit 40 can also use other existing teaching models, such as the simulated inhalation therapy nursing teaching equipment disclosed in CN202321947159.5.

[0027] In another preferred embodiment, the simulated skin layer is built with several pressure sensors (not shown in the figure) throughout the simulated human body, the signal output end of the pressure sensor is connected to the controller, and the voice output control of the controller is connected to the enabling end of the interactive system; when the operator is performing nursing exercises, the pressure sensor is used to detect the pressing force or squeezing force applied by the trainee and transmit the signal to the controller, and the controller controls the interactive system to emit a prompt sound according to the trainee's force, such as a "pain" prompt sound when the force is too large, so as to give feedback according to the trainee's operation and let the trainee learn to control the force.
