The present invention provides an infusion pump having a main body portion. The main body portion includes a display area for displaying user interface information. At least one pump module is provided which is removably secured to the main body portion and adapted to receive an IV tube. The pump module can apply pumping action to the IV tube. The pump module further includes an auxiliary display area for displaying supplemental user interface information. A microprocessor is contained in the main body portion for generating user interface information on the display areas.

Medical infusion pump

The present invention provides an estimate of the amount of time left on the battery by monitoring not only the voltage available from the battery, but also the amount of current flowing from the battery. It has been found that periodic sampling of the battery voltage and current drain enables accurate battery monitoring. The sampling technique alternates between sampling battery voltage and sampling current drain. An electric circuit is provided which enables the cost-effective sampling to occur. A method is then applied to the sampling signals by a microprocessor which determines the amount of time left under battery power. In a preferred embodiment, a graphic representation is provided of the amount of battery time left.

Battery gauge for a battery operated infusion pump

In an infusion apparatus for use in the medical field, a peristaltic pump mechanism pumps an infusion fluid including medication through an administration tube toward a patient. A clock powered independent of the apparatus counts a predetermined unit time. A CPU accumulates data representing an incremental unit of fluid of the infusion fluid delivered by the pump mechanism to measure an accumulated infusion fluid volume each time the clock counts the unit time. Data as to the current accumulated infusion fluid volume is stored in a second storage section of a RAM. Each time the clock counts the unit time, data representing the accumulated infusion fluid volume stored in the second storage section is written to a ring buffer in the RAM, so that the ring buffer stores data representing a plurality of accumulated infusion fluid volumes in one-to-one correspondence with a plurality of times at which the plurality of accumulated infusion fluid volumes were measured. The CPU accesses the buffer ring at a key-inputted request by an operator to display any desired accumulated data of the infusion fluid volume on a display unit.

Infusion apparatus capable of storing a plurality of accumulated

An infusion apparatus incorporates a RAM which has a first storage section for storing only one delivery pattern defining an infusion rate and a volume to be infused at the infusion rate, and a PDP storage section for storing a plurality of delivery patterns. In a one-pattern delivery mode, an infusion fluid is delivered according to the only one delivery pattern read out from the first storage section by a CPU. Therefore, infusion is performed at the same rate from the beginning to the end. In a PDP (Program Delivery Profile) mode, an infusion fluid is delivered according to the plurality of delivery patterns read out in sequence from the PDP storage section. Therefore, infusion is performed at various rates. One of the one-pattern delivery mode and the PDP mode is selected by an operator through operation of a mode selector in consideration of factors such as the kind of medication and the condition of the patient.

Infusion method having a plurality of delivery patterns

The present invention provides a system for automatically reconstituting a drug in-line and delivering the drug to a patient. Pursuant to the present invention, a system is provided that allows fluid entry into a vial, that houses the drug to be reconstituted, with concurrent air elimination. Mixing via different fluid entry levels is provided. Due to the unique fluid flow path of the present invention reconstitution of the drug is ensured. The system, method, and apparatus of the present invention can be utilized with a computer controlled pump. When so utilized, a completely automated procedure can be achieved.

Automatic in-line reconstitution system

The liquid transfusion apparatus according to the present invention includes a setting device adapted to respectively set a normal level of pressure of the fed liquid and an upper alarm level of pressure of the fed liquid, calculating unit for calculating a percentage of a difference between the detected level of pressure of the liquid and the set normal level to a difference between the set upper alarm level and the set normal level, and display unit for displaying the calculated percentage. The liquid transfusion apparatus is very useful for monitoring the pressure of the liquid which is being administered to a patient.
