Description

Highly adaptable laryngeal mask

Technical field

Background technique

As a medical device used to maintain patients' breathing and ventilation, laryngeal masks are widely used in clinical anesthesia, first aid or resuscitation due to their non-invasive airway characteristics. With the advancement of materials and technology, a variety of improved laryngeal masks have been used clinically.

Due to the different throat cavities of different patients, when the laryngeal mask is used for breathing and ventilation, it is often the case that the laryngeal mask cannot be effectively matched with the patient’s laryngopharyngeal cavity, resulting in the ineffective coordination of the laryngeal mask and the throat cavity, thus affecting the effect of respiratory support.

The temperature collected by the temperature sensing probe can be transmitted through wired or wireless means. When the temperature collected by the temperature sensing probe is transmitted through a wired method, the temperature A cable needs to be provided, and the cable can be buried in the mask bottom plate 1 and the breathing tube 3, but it is necessary to ensure the stability of the cable transmission signal and avoid the safety problems caused by the cable during the use of the laryngeal mask. When the temperature sensing probe adopts wireless mode to transmit the temperature signal, the specific wireless transmission form can be selected according to the needs, and will not be repeated here.

The temperature can be collected in real time through the temperature sensing probe, which can solve the current problem that the temperature of the throat cannot be collected effectively during breathing support or surgery. In the embodiment of the present invention, the temperature collected by the temperature sensing probe can be received and processed by the relevant processor. The processor can be a device with a display screen or the existing medical processing equipment, as long as the temperature sensing probe can detect the temperature. The temperature data can be received, processed, and displayed. The specific conditions are well known to those skilled in the art and will not be repeated here.
