Pump and monitor for IV pressure bag infusers

摘要

A pumping device that can be used with currently-available pressure bag infusers is disclosed. The pumping device is hand-held and lightweight. The device is controlled by a microprocessor. Thus constant pressure to the bag is maintained through automatic adjustment of pumping and venting functions. In addition, a novel, new pressure bag infuser and a modified Luer Lock fitting for use with the pumping device are described.

主权项

1. A rapid infusion pumping device, comprising:
a housing; a coupler attached to the housing, the coupler configured to attach with an airtight connection to a pressure vessel; an electric air pump in the housing, the pump in pneumatic communication with the pressure vessel via the coupler; a first pressure sensor in the housing and in pneumatic communication with the pressure vessel; a second pressure sensor in the housing configured to measure an atmospheric pressure and in pneumatic communication with an atmosphere outside of the pressure vessel; an electronic valve within the housing and in pneumatic communication with the pressure vessel; a signaling element within the housing and configured to be perceptible while observing the housing; a microprocessor within the housing and containing pre-programmed algorithms for the operation of the rapid infusion pumping device, the microprocessor in electronic communication with the pump, the first pressure sensor, the second pressure sensor, the valve, and the signaling element wherein the microprocessor receives pressure information from the first pressure sensor and the second pressure sensor and operates the electric air pump and the electronic valve to maintain a predetermined pressure within the pressure vessel; and a power source within the housing configured for supplying power to the device via the microprocessor.
