Abstract

The invention discloses a sickbed calling system, comprising at least one calling terminal; the calling terminal is accessed to a power grid by a modem and is connected with a monitoring center by the other modem respectively; the calling terminal comprises a host arranged beside a sickbed to be communicated with a nurse station, a calling handle arranged beside the sickbed to be connected and communicated with the host and a calling level button connected with the host. Only a power line is needed between the calling terminal and the monitoring center, and data information can be transferred by the 220V power grid, the sickbed calling is realized, the system is simple in structure, the cost is low, the one-time investment is less, the mounting is convenient, the operation, maintenance and management are convenient, and a patient can timely, effectively and conveniently seek help from metical staff no matter the patient is in a ward or toilet.

Description

[0001] technical field [0002] The invention relates to the field of clinical medicine, in particular to a sick bed calling system. [0003] Background technique [0004] The existing hospital bed call system uses wired connection to perform data communication, which brings a lot of trouble to the installation and construction, and the cost of installation and wiring is high. In addition, the system has a single function and cannot realize the communication between patients and medical staff in a timely and effective manner. [0005] Power line carrier communication is a power system communication in which the transmission line is used as the transmission medium of the carrier signal. Since the transmission line has a very strong support structure and more than 3 conductors (generally there are three-phase good conductors and one or two overhead ground wires), it is economical to use the transmission line to transmit the carrier signal while transmitting the power frequenc...
