Portable monitoring device for remotely monitoring a medical device
First Claim
1. A combination ofa portable monitoring device for remotely monitoring a medical device and having a signal receiver for receiving a first wireless signal, andsaid medical device in the form of a portable drip infusion set of the type comprising a liquid supply, a drip chamber downstream of said liquid supply for forming liquid drops, a flexible tube connecting said drip chamber with an injection needle and a signal emitter for emitting said first wireless signal,wherein said portable monitoring device and said medical device comprise first and second sets of electrical contacts, respectively, for mutually electrically interconnecting said portable monitoring device and said medical device for transmitting electronic data and/or electrical power between said portable monitoring device and said medical device,wherein said medical device comprises a programming device configured to program first electronic circuitry controlling the function of said medical device, said first electronic circuitry comprising a blocking device configured to block said programming function of said programming device when said portable monitoring device is not electrically connected to said medical device through said first and second electrical contacts,wherein said portable monitoring device comprises:
- a first housing, a signal receiver for receiving a first wireless signal, a first timing device for measuring a first time interval, an alarm device for emitting a first alarm, second electronic circuitry interconnecting said signal receiver, said first timing device and said alarm device for causing said alarm device to emit said first alarm if said first signal is not received by said signal receiver at the end of said first time interval, and a first battery for providing electric energy to said signal receiver, said alarm device and said timing device, andwherein said medical device comprises;
a second housing, a signal emitter for emitting said first wireless signal, a second timing device for measuring said first time interval, third electronic circuitry interconnecting said timing device and said signal emitter for causing said signal emitter to emit said first signal at the end of said first time interval, and an electric power supply for providing electric energy to said timing device and said signal emitter.

Abstract
A portable monitoring device operates to remotely monitor a medical device for use in hospitals and the like. The portable monitoring device includes a signal receiver for receiving a first wireless signal. The medical device can be a portable drip infusion set of the type having a liquid supply, a drip chamber downstream of the liquid supply for forming liquid drops, a flexible tube connecting the drip chamber with an injection needle and a signal emitter for emitting the first wireless signal. The infusion set and the monitoring device each can include printed circuit boards (PCBs) and mutually interconnectible electric contacts. The infusion set includes an electronic circuitry that blocks programming of the infusion set when the monitoring device is not electrically connected to the infusion set.
