Abstract
The present disclosure relates to administration of fluid medication, in particular medication and dosing regimen for management of pain, more specifically to an anesthetic and dosing regimen for anesthetic for perioperative pain management and/or for palliative care. The present disclosure relates further to a medication pump and a method for delivering medication using the medication pump.
Core Innovation
The invention describes a wearable administration system configured for delivering a time-controlled periodic infusion of medication to a target. The system includes a medication pump and a control unit that automatically operates the medication pump to periodically infuse the medication.
The periodic infusion is defined by a preset infusion sequence using flow rates between 30 mL/h and 1200 mL/h, an infusion volume between 1-20 mL, and an infusion time between 1-20 minutes, with a period of 1-48 hours. The system provides a time-controlled periodic infusion structure positioned within a dosing regimen that alternates between infusion times and dwell periods.
The document further describes embodiments with different infusion sequence patterns as constant flow, increasing/decreasing flow, and pulse trains, and includes support for catheter-based delivery. It also describes system components such as a power supply using batteries and a control architecture including a real-time clock and an encoder.
Claims Coverage
The partial content provides two independent claims: an apparatus claim and a method claim. The independent claims share a common dosing concept based on an automatically operated time-controlled periodic infusion with specific flow-rate and infusion-time/volume ranges, separated by a period of 1-48 hours.
Wearable administration system with periodic infusion parameters
A wearable administration system configured for delivering a time-controlled periodic infusion of medication to a target, comprising a medication pump and a control unit configured to automatically operate said medication pump to periodically infuse said medication utilizing flow rates between 30 mL/h and 1200 mL/h to define a preset infusion sequence with an infusion volume of between 1-20 mL during an infusion time of between 1-20 minutes with a period of 1-48 hours.
Method with automatically operating periodic infusion and repeating after dwell
A method for delivering a time-controlled periodic infusion of medication to a target from a wearable administration system comprising a medication pump and a control unit, comprising infusing said medication utilizing flow rates between 30 mL/h and 1200 mL/h to define a preset infusion sequence with an infusion volume of between 1-20 mL during an infusion time of between 1-20 minutes by automatically operating said pump via said control unit; waiting a period of 1-48 hours; and repeating a-b.
Both independent claims cover a wearable administration system and a corresponding delivery method that use an automatically operated medication pump to infuse medication at flow rates between 30 mL/h and 1200 mL/h to form a preset infusion sequence with an infusion volume of 1-20 mL over 1-20 minutes, repeated with a period of 1-48 hours.
