Clinical help calls are the main means of transmitting clinical information, Medical pager It is a special tool for patients to require doctors or nurses on duty to carry out diagnosis or nursing. It can quickly transmit patients' regulations to doctors or nurses on duty, and leave accurate and complete records on the computer of the monitoring center in the duty room. It is one of the necessary equipment to improve the level of outpatient and ward care in the hospital.
The quality of the call system has a direct impact on the safety of patients, and has received extensive attention from major hospitals over the years. Its provisions are timely, accurate, reliable, simple, feasible and conducive to promotion. The hospital bed call system with the functions of calling, ringing, displaying queuing, priority setting, and storing records, which uses the power line carrier communication technology and single-chip microcomputer to design the technical design scheme of multi machine communication and electronic computer monitoring management, meets the hospital outpatient ward management and nursing regulations.
Design Principle of Hospital Ward Call System
The room call system consists of several call sources (generally one for each hospital bed), modulation and demodulation carrier module, coupling circuit and monitoring system software. When the call source has a call data signal, the corresponding audio and optical call data signal indication is displayed on the video monitoring system, and the call number can be displayed. If the parallel processing bus expansion mode is adopted, the wiring between hundreds of call sources and servers is too complex, so the system software uses the serial communication function designed by the single-chip microcomputer to make the data signals from the server to each slave computer pass through the power line carrier modulation and demodulation module, and pass through the civil power line to realize the dual data transmission between the server and the slave computer.
The design scheme of hospital ward call system is almost a required course in hospital outpatient building engineering, and its quality and efficiency directly affect the efficient service level of hospital outpatient service. At the same time, the design scheme of hospital ward call system is also a work with high technical content, which can be completed only if the relevant technical personnel, the hospital and the construction unit cooperate with each other.
