A cricothyrotomy medical training device includes a ribbed tube representative of a human trachea, the ribbed tube having a first end and a second end. A first protrusion extends from the first end of the ribbed tube, the first protrusion being representative of a human thyroid cartilage. A second protrusion extends from the ribbed tube near the first end, the second protrusion being representative of a human cricoid cartilage. The second protrusion is longitudinally spaced between the first end and the second end. A first marking material is disposed at the first and second protrusions for representing a location of human skin. A second marking material disposed between the first and second protrusions to identify a location of a human cricothyroid membrane.

This invention relates to the field of laryngoscope technology, specifically to a high-frequency jet video laryngoscope integrating multimodal functions and its usage method. The invention includes a laryngoscope body, and integrated on the laryngoscope body are a high-frequency jet ventilation module, a visualization and anti-interference module, a multi-functional channel module, and a puncture guidance module. The laryngoscope body, from top to bottom, includes a video display unit, a drug delivery control unit, an operating handle unit, and a flexible insertion unit. The high-frequency jet ventilation module provides high-frequency airflow for ventilation and oxygenation. The visualization and anti-interference module provides a visual field for cricothyroid membrane puncture and avoids airflow interference. The multi-functional channel module provides multi-functional assistance for puncture guidance. This technical solution, by integrating high-frequency jet ventilation, visualization and anti-interference, and multi-functional channel modules, achieves ventilation and oxygenation, clear visual field presentation, precise puncture guidance, and multi-functional assistance, thereby more comprehensively, efficiently, and safely meeting the treatment needs in complex medical scenarios.

This invention discloses an automatic cricothyroid membrane puncture and cannulation gun, belonging to the field of medical device technology. It includes a gun body with a gun head at the front. An arc-shaped positioning support is located at the front end of the gun head. An expansion sleeve is slidably disposed within the gun head, containing a puncture needle core. A linear drive mechanism is located at one end of the expansion sleeve within the gun body's casing. A catheter pushing mechanism is located on the outer wall of the gun body near the gun head, pushing a catheter assembly. The catheter assembly is slidably disposed within the expansion sleeve, and a tapered hole is formed at the proximal end of the expansion sleeve for the catheter assembly to pass through. This invention adopts an integrated design for puncture, expansion, and cannulation, significantly shortening the emergency airway establishment time and reducing the skill requirements for operators. It is suitable for complex emergency scenarios such as wartime battlefields and disaster relief, improving the efficiency and safety of first aid and wartime trauma treatment.

The application discloses a kind of intelligent cricothyroid membrane puncture equipment, it is related to cricothyroid membrane puncture technical field, including shell, one end of the shell is fixedly connected with mounting disc, the one side of the mounting disc is fixedly connected with fixed cylinder, the one end of the fixed cylinder is fixedly connected with installation pipe, and the one end of the installation pipe is provided with glue paste.The intelligent cricothyroid membrane puncture equipment disclosed in the application makes the first air bag and the second air bag of the one end of the air hose driven by the puncture needle move together, the steel wire drives the puncture needle to pierce the cricothyroid membrane from the neck of patient, makes the first air bag and the second air bag stay inside the cricothyroid membrane, makes the one end of the air hose fixed on the cricothyroid membrane of patient after the metal support is pried open, connects the breathing machine with the universal connecting end of the one end of the breathing tube, the inside of the breathing tube and the air hose is communicated with the inside of the trachea of patient, provides breathing guarantee for patient in emergency and reduces the effect of cricothyroid membrane injury of patient.

The application provides a cricothyroid membrane puncture rescue simulation training method and system, a cricothyroid membrane puncture rescue simulation training method comprising the following steps: step S1, starting an infrared locator, a pressure-sensitive puncture needle and a head-mounted display, and establishing a connection; step S2, calibrating the head-mounted display coordinates; step S3, the infrared locator determines the positions of the pressure puncture needle, the head-mounted display and the elastic simulation human body, and transmits the position information to the head-mounted display; step S4, the head-mounted display updates the position according to the received position information; step S5, the head-mounted display renders the training scene and produces environmental sound; step S6, the training personnel perform a cricothyroid membrane puncture action; step S7, the contact module in the head-mounted display judges whether the puncture reaches the specified position; step S8, when the training personnel puncture to the specified position, the pressure puncture needle is fixed, and training evaluation is prompted and given; and step S9, the training is completed. The beneficial effect is that the cost of training construction is controlled, and more realistic feedback experience can be given to students.

The application provides a cricothyroid membrane puncture guiding device, which has the structure comprising: an ultrasonic contact block, a control handle, a display screen, a switch button and an adjusting button. The ultrasonic contact block is connected with the control handle, and the control handle starts the display screen and the adjusting button through the switch button. After the ultrasonic contact block is improved, the sponge pad of the arc block can directly contact the skin at the position of the cricothyroid membrane, which can improve the safety factor during contact. Then, the vertical sleeve of the fixing structure is used to make the sliding rail drive the push rod to slide down, and the plug is inserted into the sickbed, so that the positioning effect is achieved. The shaking and instability during the simple handheld guiding detection can be avoided, the accuracy of the guiding puncture is improved through the fixation with the sickbed, the probability of single puncture success is further improved, and therefore the use intensity of the guiding device is improved.
