Music display screen for medical nursing communication

Abstract

The invention belongs to the field of nursing communication systems for hospitals and discloses a music display screen for medical nursing communication. The music display screen comprises a power circuit, an alternating-current high-resistance circuit, a code receiving circuit, an audio communication circuit, a volume adjustment circuit, a power amplifying circuit, a display circuit and a master controller. The music display screen is characterized in that an input end of a control circuit is connected with an external two-core bus, an output end of the control circuit is connected with the information display circuit, a display device adopts an ultrathin highlight nixie tube device or component, the alternating-current high-resistance circuit provides a display power source, the code receiving circuit receives information, the audio communication circuit and the power amplifying circuit receive audio frequencies of the bus, and the volume adjustment circuit adjusts ring volume. The music display screen for medical nursing communication has the advantages that calling extension numbers for nursing communication can be displayed while voice number reporting information or ring music of a nursing communication mainframe can be played by a corridor display screen terminal to make it convenient for medical personnel to confirm calling positions; the requirements on volume in different time periods can be met owing to the volume adjustment function; the music display screen is widely applicable to hospital ward communication calling systems.

Description

technical field [0001] The invention provides a medical nursing communication music display screen, which belongs to the field of hospital nursing communication systems. Background technique [0002] The nursing communication display screen hanging in the hospital ward corridor can display the current time and ward call information at any time, and its two-wire bus has been recognized by the majority of users because of its advantages of less wiring, simple wiring, convenient installation, and easy maintenance; but Nowadays, many hospitals require that the display screen in the corridor can be synchronized with the ringing number of the host computer in order to improve the work efficiency of nurses. At present, the common method is to carry out special modification on the display screen, which reduces the stability of the system and relatively increases the cost. [0003] The patent No. CN200820224131.8 discloses a "display screen with nursing level display", including an ...

AI Technical Summary

Problems solved by technology

[0004] The above patents use a two-wire power supply. This patent can simply distinguish call information; however, it cannot realize the requirement that the nurses in the corridor accept the call information when the extension calls.

And it is impossible to achieve compatibility when the input is of different voltages, thus increasing the complexity of the entire nursing communication system and increasing the difficulty of installation and maintenance
