Description

Technical Field

[0001] The invention relates to the technical field of cardiopulmonary resuscitation teaching model equipment, in particular to a cardiopulmonary resuscitation teaching model that is easy to clean. Background Art

[0002] In the relevant teaching of cardiopulmonary resuscitation, cardiopulmonary resuscitation models are often used for simulation operations. In the existing technology, the head of the cardiopulmonary resuscitation model is provided with an oral cavity and a nasal cavity, and a trachea is buried in the neck, and the lower end of the trachea is located in the chest cavity; a bracket is fixed in the chest cavity, but when simulating artificial respiration, droplets that may contain pathogens are easily sprayed into the trachea, causing the possible pathogens in the droplets to remain in the trachea, which is easy to cause cross-bacterial infection or virus transmission of personnel. If you want to remove the trachea for cleaning, the operation is also more troublesome and not conducive to use. In addition, students are prone to make mistakes in strength or position during practice, and need timely guidance. To this end, we propose a cardiopulmonary resuscitation teaching model that is easy to clean. Summary of the invention

[0003] The purpose of the present invention is to provide a cardiopulmonary resuscitation teaching model that is easy to clean, so as to solve the problems raised in the above-mentioned background technology.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the cardiopulmonary resuscitation teaching model that is easy to clean has a simple and reasonable structural design. By arranging a connecting sleeve and a protective cover at the top of the trachea as a droplet interceptor, the inverted cone-shaped conical sleeve is used to, on the one hand, block part of the droplets from moving downward, and prevent the droplets carried in the airflow from diffusing in the tube body, thereby inhibiting the droplets from contaminating the tube body and promoting the maintenance of the cleanliness of the tube body. On the other hand, it is used to gather the airflow and droplets blown in by the user, so that the airflow blown out by the user can be purified, thereby effectively ensuring the cleanliness of the tube body. By arranging a detachable pressing layer in the chest cavity of the model main body, the cooperation of the first magnet and the second magnet makes it convenient to disassemble and install the pressing layer, thereby facilitating its cleaning and maintenance. By arranging the springs, telescopic rods, elastic plates and other structures used in conjunction, the human body pressing experience can be well simulated, and the use effect of the device can be improved.
