Device for the intermittent pulsatory application of fluid medicaments
First Claim
1. A portable apparatus adapted to be worn by a patient user for the intermittent pulsatory application of fluid medicament comprising:
- a disposable reservoir and hose assembly including a flexible reservoir container for medicament, a hose communicating between the reservoir container and a hose pumping portion having its discharge end in fluid communication with a catheter;
a roller-type pump means including a a head portion rotatable about an axis of rotation and having angularly spaced rollers adapted to act on said hose pumping portion;
a D.C. motor for driving said pump means;
control means for controlling said motor including a timer for pulse and pause times;
battery means for supplying electrical energy to said motor, and an openable housing and a frame cooperating to enclose and mount the pump means, motor, control means, battery means, and reservoir and hose assembly with said catheter extending from said housing for delivery of the medicament to a patient;
said housing and frame cooperating to provide a recess for receiving said reservoir container and a pair of hose mounts for removably mounting said reservoir and hose assembly;
a collar fixed to each end of said hose pumping portion;
each of said collars being adapted to be resiliently biased into engagement with an associated one of said hose mounts with said hose pumping portion extended elastically through said hose mounts and tensioned against said rollers;
said hose pumping portion, hose mounts and rollers being visible and directly accessible upon opening of said openable housing to enable insertion and removal of said reservoir and hose assembly without further disassembly of said apparatus.

Abstract
A device for the intermittent pulsatory application of fluid medicaments, particular for the application of LH-RH for initiating ovulation in women having hypothalamic and hyperprolactinamic amenorrhea. Said device has a reservoir for the medicament and a hose connected to said reservoir for delivering said medicament to a patient, which reservoir and which hose are a prefabricated unit which can be inserted into the device and removed when the content of the reservoir is exhausted. Furthermore, said device has a roller-type pump acting onto said hose when it is stretched onto the needle-like rollers of said roller-type pump, and a D.C. motor for driving said pump and further control means for controlling said motor, said control means having a timer for pulse and pause times so that the motor is energized only for short periods not longer than several minutes while it is between each two of such running periods stopped for more than one hour. At least one battery is provided as energy source for the D.C. motor.
