Technical Field

[0001] The invention belongs to the field of medical auxiliary technology, and in particular relates to a craniocerebral injury simulation human teaching model. Background Art

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

[0003] However, the aforementioned nursing teaching mannequins are not suitable for teaching craniocerebral injury, and existing craniocerebral teaching models are mostly used for craniocerebral anatomy, such as the teaching craniocerebral model device disclosed in CN202410275484.4, the craniocerebral model disclosed in CN201810609746.0, or the craniocerebral anatomy and imaging teaching model disclosed in CN202110239846.0, which are not suitable for teaching craniocerebral injury.

DETAILED DESCRIPTION

[0017] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0018] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[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 communication between two components. It can be a direct connection or an indirect connection through an intermediate medium. 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. The simulated human body includes a head with facial features, a torso with a chest, abdomen, internal organs, and reproductive organs, and limbs connected to the torso. The head includes a cranial simulation unit 10 for simulating cerebral edema, cerebral hematoma, brain fracture, brain hernia, and cerebrospinal fluid leakage; the torso includes a urinary system simulation unit 20, a blood circulation system simulation unit 30, and a respiratory system simulation unit 40. The cranial simulation unit 10, urinary system simulation unit 20, blood circulation system simulation unit 30, and respiratory system simulation unit 40 are connected to a controller (not shown).

[0021] The controller is pre-set 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 pre-set control programs in the controller are existing technology and will not be described in detail here); the operator selects different brain injuries and performs nursing operations on the brain injuries and the resulting complications of the urinary system simulation unit 20, the blood circulation system simulation unit 30, and the respiratory system simulation unit 40.

[0022] With this technical solution, by setting up a cranial brain simulation unit 10, a urinary system simulation unit 20, a blood circulation system simulation unit 30, and a 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 operation of 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 simulate brain injury and its complications, and the operator performs care. For example, when increased intracranial pressure (specifically, it can be caused by cerebral edema, cerebral hematoma, cerebral hemorrhage, hydrocephalus, and intracranial inflammation) leads to severe damage to neurological function, it may cause urinary incontinence. 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.

[0023] In the present invention, the brain simulation unit 10 includes a skull 11 with a removable skull cap 12 attached to the top. The skull cap 12 opens and closes with the corresponding simulated skin layer. A fracture is artificially created in the skull 11 to simulate a brain fracture. Within the skull 11 is a brain tissue model 13, and between the skull 11 and the brain tissue model 13 lies a blood sac 15 for simulating a cerebral hematoma. The blood sac 15 is filled with liquid to simulate the compression of brain tissue by a cerebral hematoma. The brain tissue model 13 contains a cerebral vascular model 14, simulated cerebrospinal fluid, and a water sac for simulating cerebral edema, namely a first water sac 16. The first water sac 16 is filled with liquid to simulate the phenomenon of increased brain volume caused by cerebral edema. The intracranial pressure is increased by filling the cerebral vascular model 14 and the simulated cerebrospinal fluid with liquid and applying pressure. Specifically, a micropump 17 can be provided to fill the cerebral vascular model 14 and the simulated cerebrospinal fluid to cause a sharp increase in intracranial pressure to simulate brain herniation. The micropump 17 can also be used to fill the blood sac 15 and the first water sac 16 with liquid to increase their volume, thereby increasing intracranial pressure to simulate brain herniation. The brain tissue model 13 can be artificially damaged to cause simulated cerebrospinal fluid leakage to simulate cerebrospinal fluid leakage. The cerebral vascular model 14 can also be damaged to simulate cerebral hemorrhage.

[0024] In the present invention, the urinary system simulation unit 20 includes a bladder model 21, which contains a water-filled water bag, known as a second water bag 22. This water bag is filled with water to simulate urine in the bladder. The second water bag 22 is connected to the bladder model 21, which is connected to a urethral tube 23 equipped with a valve 24. The urethral tube 23 is inflatable, specifically by providing an air pump 25 to inflate the urethral tube 23 (with valve 24 closed during inflation), preventing the water in the second water bag 22 from draining properly, thereby simulating urinary retention. When the urethral tube 23 is not inflated, the water in the second water bag 22 can be drained from the urethral tube 23 by opening valve 24, simulating urinary incontinence.

[0025] In the present invention, the blood circulation system simulation unit 30 includes a heart model 31, which is connected to a pump, namely a blood pump 32. The pressure and frequency of the blood pump 32 can be adjusted to simulate arrhythmia and blood pressure fluctuations; the blood vessel models 50 of the limbs are provided with a gel release mechanism 51, which releases gel in the blood vessel model 50 to simulate abnormal blood coagulation in the deep veins, which is used to simulate deep vein thrombosis.

[0026] In the present invention, the respiratory system simulation unit 40 includes a lung model 41 and an airway model 42 connected to the lung model 41. The airway model 42 contains simulated sputum and is connected to the mouth and nose of the head. This allows trainees to perform cardiopulmonary resuscitation and sputum suctioning exercises through the respiratory system. The respiratory system simulation unit 40 may also utilize other existing teaching models, such as the simulated inhalation therapy teaching device disclosed in CN202321947159.5.

[0027] In another preferred embodiment, the simulated skin layer is equipped with several pressure sensors (not shown in the figure) throughout the body of 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 enable end of the interactive system. When the operator performs nursing exercises, the pressure sensor is used to detect the pressing or squeezing force applied by the trainee and transmits the signal to the controller. The controller controls the interactive system to emit a prompt sound according to the trainee's force, such as a "pain" prompt sound when too much force is applied, to provide feedback based on the trainee's operation, allowing the trainee to learn how to control the force. Preferably, the interactive system is an intelligent speaker that can answer questions asked by the trainee to achieve human-computer interaction.
