Description

Ward emergency call device with pull rope and waterproof function

Technical Field

The utility model relates to the technical field of emergency calls, in particular to the field of ward emergency call devices with pull ropes and waterproof functions.

Background

Hospitals often require emergency call devices to be installed in a bathroom in order to meet the needs of the patient. Once someone presses the call button in the bathroom in the ward, the host computer at the nurse station sends out audible and visual alarm signals to cope with emergency situations of patients in the bathroom. Emergency call devices equipped with a pull-cord switch are a common product design. When the user uses the pull rope, the user can call nurses and nursing workers by pulling down the pull rope, and the use mode can meet different operation preferences of the user, so that the operability of the product is improved. However, the product usually needs to trigger a switch when the pull-down stroke of the pull rope is large, has poor hand feeling, and has safety risk when the pull rope cannot be pulled down by the patient's limb with inconvenience.

Because the air in a toilet is usually moist, the product is required to have a waterproof function, so that the circuit board in the product is completely sealed. The existing scheme is that waterproof sealant is filled between the shell and the circuit board, so that the circuit board is isolated from the outside air when the circuit board is fixed. The glue filling amount of the scheme is difficult to control, and the glue is easy to lose functions due to the fact that the glue is not touched by a switch. Meanwhile, the glue curing time is long, the production efficiency is affected, and the circuit board is easy to float up in the glue curing process, so that the touch key is dead and the function is lost. After the glue is solidified, the circuit board cannot be detached, and after-sales maintenance is affected.
