Abstract

"BOMBA DE INFUSãO E PROCESSO DE INFUSãO DE LìQUIDO TERAPêUTICO PARA UM PACIENTE". Uma bomba de infusão (10) inclui um reservatório (18) contendo um líquido terapêutico a ser infundido. O reservatório (18) inclui uma saída (36) para o líquido. Uma bomba de ar volumétrica (24) é operacionalmente associada com o reservatório (18) para pressurizar o reservatório e dessa forma acionar o líquido para fora da saída (36). Uma válvula (12) é operacionalmente associada à saída (36) e impede o fluxo de líquido através da saída até que uma pressão limite selecionada seja obtida na saída. A válvula depois disso mantém uma abertura na saída que mantém a pressão no reservatório (18) substanciamente na pressão limite selecionada, onde a taxa de fluxo volumétrico do líquido através da saía (36) é proporcional à taxa de fluxo volumétrico de ar da bomba de ar volumétrica (24). A válvula (12) varia a abertura na saída para manter a pressão selecionada. A saída consiste preferivelmente de um conduíte flexível (36) possuindo uma área transversal interna não deformada e selecionada e a válvula (12) restringe de forma variável o fluxo de líquido através da saída apertando um segmento do conduíte para variar a área transversal interna do segmento do conduíte. Um processo de infusão de líquido terapêutico para um paciente inclui o fornecimento de um reservatório (18) contendo um líquido terapêutico, fornecendo uma bomba de ar volumétrica (24) para pressurizar o reservatório para fluir o líquido para fora do reservatório de líquido através de uma saída (36) e manter uma pressão selecionada no reservatório de forma que o líquido através da saída de líquido seja proporcional à taxa de fluxo volumétrica da bomba de ar volumétrica."INFUSION PUMP AND THERAPEUTIC LIQUID INFUSION PROCESS FOR A PATIENT". An infusion pump (10) includes a reservoir (18) containing a therapeutic liquid to be infused. The reservoir (18) includes an outlet (36) for the liquid. A volumetric air pump (24) is operationally associated with the reservoir (18) to pressurize the reservoir and thereby drive the liquid out of the outlet (36). A valve (12) is operationally associated with the outlet (36) and prevents liquid from flowing through the outlet until a selected limit pressure is obtained at the outlet. The valve thereafter maintains an opening in the outlet that maintains the pressure in the reservoir (18) substantially at the selected limit pressure, where the volumetric flow rate of the liquid through the outlet (36) is proportional to the volumetric air flow rate of the air pump. volumetric air (24). The valve (12) varies the opening at the outlet to maintain the selected pressure. The outlet preferably consists of a flexible conduit (36) having an internal non-deformed and selected transverse area and the valve (12) varies the flow of liquid through the outlet in a variable way by tightening a conduit segment to vary the internal transverse area of the segment the conduit. A therapeutic liquid infusion process for a patient includes providing a reservoir (18) containing a therapeutic liquid, providing a volumetric air pump (24) to pressurize the reservoir to flow the liquid out of the liquid reservoir through a outlet (36) and maintain a selected pressure in the reservoir so that the liquid through the liquid outlet is proportional to the volumetric flow rate of the volumetric air pump.
