This invention relates generally to monitoring systems and more particularly concerns devices and systems used to monitor patients the presence and absence of a patient from a bed, chair, etc. The preferred environment in which the instant invention would be used would be a hospital or other care giving facility, wherein patients who are at risk of falling might left unattended while they are seated or lying. According to a first aspect of the instant invention, a microprocessor-based patient monitor is disclosed which includes a loudspeaker that emits alarms synthesized by the microprocessor. The microprocessor synthesizes any one of multiple alarm sounds under software control and activates and deactivates the alarm in response to the electronic signals received from an attached sensor and a user interface.

Microprocessor based bed patient monitor

This invention relates generally to monitoring systems and more particularly concerns devices and systems used to monitor patients lying in hospital beds or in other care giving environments. According to a first aspect of the instant invention, a microprocessor based patient monitor is disclosed which includes a loudspeaker driven by a power amplifier responsive to an input signal derived from a programmable volume control. The microprocessor synthesizes any one of multiple alarm sounds under software control, operates the programmable volume control of the alarm system and activates and deactivates the alarm in response to the electronic signals received from the sensor and a user interface. An electrically erasable programmable read-only memory accessible by the processor stores data which can be modified to tailor the operations of the monitor to suit a variety of different needs. According to still another aspect of the instant invention, a microprocessor-based patient monitor is disclosed which has a personality that is defined by software that is resident in modifiable nonvolatile memory, which software can thus be altered to change the programmed responses of the monitor. Finally, a software and hardware system is provided for reading information from and writing information to modifiable nonvolatile RAM within a microprocessor-based patient monitor. This information might be parameter settings, data values, or computer instructions.

This invention relates generally to monitoring systems and more particularly concerns devices and systems used to monitor bed patients in hospital or other care-giving environments. In accordance with a first aspect of the instant invention, there is provided a binary switch-type device (e.g., a &ldquo;mat&rdquo;) for use in patient monitoring situations which contains, in addition to a conventional patient detection circuit, identification circuitry that can be sensed by an attached electronic monitor. The identification circuitry can be sensed by the electronic monitor and is designed to be configured to serve many different purposes, including, by way of example only, identification of the type of mat attached thereto, detection of connectivity problems, tracking mat usage time, and identifying mats that are nearing the end of their useful lives.

Smart binary switch for use with an electronic patient monitor

A holster for a bed monitor electric control module consists of two substantially rigid continuous wire loops bent into identical inverted-Ls of height less than a height of the module and held in back-to-back spaced apart relationship by upper and lower substantially rigid parallel wire cross members fixed to rearward vertical portions of the inverted-Ls. The cross members are of length and the upper horizontal portions of the inverted-Ls are of contour so as to constrain horizontal movement of a module which is inserted downwardly therein and seated on the lower horizontal portions of the inverted-Ls. A hanger is formed from a resiliently flexible wire bent into a configuration compatible with the holster and which can be flexed to permit insertion cf the hanger into the holster, manipulation of the hanger within the holster and release of the hanger into interlocking relationship with the holster so as to constrain movement of the holster relative to the hanger. To disengage the hanger from the holster, the hanger is again flexed, manipulated and withdrawn from the holster.
