The patient call system, in accordance with the principles of the present invention, is adapted to retrofit onto a preexisting patient call system. The patient call system, retrofit onto the preexisting system, consists of a patient call unit which is securely mounted on a patient using a wristband or strap and a wall unit retrofit mounted near the preexisting patient call system room port. The patient call unit allows the patient to activate a user actuated control electrically coupled to a transmitter which generates a radio frequency (RF) patient call signal. The wall unit, which is in communication with the RF transmitter in the patient call unit, receives the patient call signal and produces a patient alarm signal. The wall unit is electrically coupled to the preexisting room port and sends the patient alarm signal to the room port upon receipt of the patient call signal. The wall unit is programmed either to send the patient alarm signal in the same form as the preexisting hard-wired patient call switch or to activate the preexisting room port to generate the alarm. The patient alarm signal is then received by the preexisting central monitoring station in the same manner as if the alarm signal had been sent by the preexisting patient call switch. The retrofit patient call system includes a coupling interface with the preexisting patient call switch (such as a T coupler) to permit a healthcare facility to utilize both the present invention and the preexisting patient call switch (the switch at the end of the flexible cable or conductors). The patient call unit may include a fall detector electrically coupled to the transmitter. If the patient falls or the fall detector otherwise detects an abrupt jarring (a measurement of acceleration), the transmitter sends an RF patient call signal to the wall unit. The wall unit may include a display which displays information such as time elapsed since receipt of a patient call signal, the time of receipt of a patient call signal, programming information and power source information. The wall unit may also include a reset switch to reset the system after receipt of a patient call signal. The wall unit can be programmed to send multiple patient alarm signals at predetermined time intervals to the preexisting patient call system after receipt of a patient alarm signal from the patient call unit typically strapped to the patient's wrist.

The nebulizer includes a housing, a compressed gas inlet, an orifice ejecting the gas as a gas jet and liquid medicament entrained into the gas jet and forming a spray. The spray is directed to a spheroidal diffuser (preferably a ball) mounted beneath a cap forming a substantially cylindrical space within which swirls or spins the deflected spray jet. An opposing diffuser plate, opposite the downwardly open end of the cap, provides additional deflection as does specially shaped legs spacing the cap form the deflector-diffuser plate. The diffuser plate has a deflection edge about its periphery (either a full deflector edge, or several 45 degree arcuate edges, or small arcuate segments) which edge causes additional deflection and diffusion of the aerosol.
