An ad hoc network wireless video image laryngoscope system

Abstract

The invention relates to an ad-hoc network wireless video image laryngoscope system which comprises a wireless video image laryngoscope, a receiving and displaying device and an image display. A video processor module is arranged in a handle component of the wireless video image laryngoscope, and a storage module, a digital camera input module and a Wi-Fi module are connected with the video processor module. A power management module is further arranged in the handle component. The receiving and displaying device can be a special wireless receiver is provided with a CPU module, a storage module, a VGA / HDMI module and a Wi-Fi module are connected with the CPU module, a power management module is further arranged in the special wireless receiver, the receiving and displaying device can be an Android smart mobile terminal, and through a corresponding video decoder, video compression bit streams can be wirelessly received, decoded and played. Through the advanced video compression technology and the digital wireless transmission technology, high-definition video images can be achieved and can be displayed through multiple screens.

Description

technical field [0001] The invention relates to an ad hoc network type wireless video image laryngoscope system. Background technique [0002] At present, the laryngoscope is widely used in surgical anesthesia and tracheal intubation. It consists of a holder that doubles as a handle and a battery box, and a curved tongue depressor that is used to press the tongue to provoke the epiglottis and expose the glottis. , the front is equipped with an anti-fog camera and a small LED light for lighting during intubation. The use of the laryngoscope helps the medical staff to accurately expose the glottis during the operation, quickly complete the endotracheal intubation, improves the success rate of an intubation, and facilitates anesthesia and first aid. For example, the Chinese invention patent with the patent number of 200910050546.7 proposes an electronic video multifunctional laryngoscope, but its display screen and operating handle are integrated, which brings inconvenience in...

Problems solved by technology

For example, the Chinese invention patent with the patent number of 200910050546.7 proposes an electronic video multifunctional laryngoscope, but its display screen and operating handle are integrated, which brings inconvenience in operation, because the movement of the operating handle will cause the display angle to change. changes, which will affect visual observation; the invention patent with the patent number of 201210212471. A portable wireless video laryngoscope, the device realizes wireless transmission but adopts traditional analog transmission technology, which has poor anti-interference performance and cannot realize networked and remote transmission

To sum up, the main problems of the current video laryngoscopes are: (1) Whether it is a wired video laryngoscope or a wireless video laryngoscope, the analog transmission of video signals is used, and informationization, networking, and remoteness still cannot be realized

(2) Existing portable laryngoscopes generally integrate a small LCD display (1.7 inches or 3.5 inches) on the handle, with a small field of view and low resolution, often only 320*240 or even lower. Anesthesia and medical teaching occasions are greatly restricted

(3) A video compression algorithm with a high compression rate is not used, and the transmission and storage of video information consumes a lot of resources

(4) The power consumption is generally high, and the standby and battery life are short, requiring frequent charging and replacement of equipment
