Some embodiments an infusion pump system can be configured to modify alarm limit parameters as the user's insulin load increases or decreases. Moreover, in particular embodiments, the infusion pump system can be configured to provide a “missed bolus” or “missed meal” alarm in response to the user's blood glucose characteristics, the user's insulin load information, or the like.

Infusion pump system and methods

An apparatus for delivering a bolus of a medical agent to a patient. The apparatus comprises a pump mechanism, a data input device, and a processor in data communication with the keypad and arranged to control the pump mechanism. The processor is programmed to receive data specifying a bolus amount through the data port, receive data regarding duration through the data port, receive a percentage through the data port, the percentage defining a portion of the bolus amount to deliver immediately upon executing a deliver command and a remainder of the bolus amount to deliver over the duration upon executing a deliver command, and execute the deliver command thereby controlling the pump mechanism to deliver the bolus. Also a method of temporarily adjusting the delivery rate of an infusion pump. The infusion pump is programmed to deliver a basal rate. The method comprises prompting a user to select whether to enter the temporary rate as a percent of the current delivery rate or as a new delivery rate; entering into the pump a period of time having a beginning and an end; entering into the pump a temporary basal rate; and delivering the therapeutic agent at a delivery rate substantially equal to the temporary basal rate during the period of time.

There is great demand for micro- or miniaturized actuators for practical application. However, magnetic coils of electromagnetic motors are an obstacle to such miniaturization because of their complicated construction. Furthermore, electrostatic micro-motors fabricated by IC-processing cannot generate sufficient output power. Piezoelectric motors are promising because of their simple construction and high power density. In fact, some piezoelectric actuators have been or are close to being launched in the market. For their miniaturization, proper fabrication processes including thick deposition methods are important. In this review, various principles of piezoelectric motors are introduced in addition to suitable fabrication processes.

Miniature piezoelectric motors

Some embodiments of a medical infusion pump system include a pump device and a removable controller device. When the pump device and the removable controller device are removably attached to one another, the components may provide a portable infusion pump unit to dispense medicine to a user. In particular embodiments, the removable controller device includes a user interface to readily provide information, for example, about the operation of the pump.

A low cost portable dosing apparatus enables the dispensing rate to be changed while enabling solution to be continuously dispensed to the body. The solution to be dispensed into the body is stored in a tank unit. A pump unit pumps the solution from the tank unit into the body of the patient. A controller controls pump unit operation. The tank unit, pump unit, and controller are attached to a wrist strap so that they can be easily connected and disconnected from each other. A compact, thin ultrasonic motor with high output per unit size drives the pump unit. A smaller pump unit is thus available, improving the portability of the apparatus. The ultrasonic motor is also substantially free of misoperation resulting from exposure to magnetic fields because the ultrasonic motor is not magnetically driven. Reliability is therefore improved.

Portable dosing apparatus

PROBLEM TO BE SOLVED: To provide a portable liquid drug administration device that is inexpensive, and administers a liquid drug at variable rates and continuously. SOLUTION: A tank portion 2 holding a liquid drug of a portable drug administration device 1, a pump portion 3 delivering the liquid drug in the tank portion 2, a control portion 4 controlling the pump portion 3, are mounted detachably. When a small (flat) ultrasonic motor 5 whose output per unit area is large is used as a driving source of the pump portion 3, the volume of the pump portion decreases, the portability of the portable liquid drug administration device improves, and as the ultrasonic motor 5 is not driven magnetically, there is no possibility of a malfunction even in the vicinity of a magnetic equipment and also reliability is improved.

Portable liquid drug administration device

An ultrasonic motor has a piezoelectric element driven by application of a voltage thereto to undergo expansion and contraction. A vibrating body is vibrationally driven by the expansion and contraction movement of the piezoelectric element to thereby produce standing waves. A moving body is frictionally driven by the standing waves of the vibrating body. Power transmission projections apply a frictional force to the moving body to thereby frictionally drive the moving body in accordance with the standing waves. The power transmission projections are disposed only every preselected number of wavelengths at intermediate positions between loops and nodes of the standing waves, the preselected number being a natural number.

PROBLEM TO BE SOLVED: To provide a curving device fitted to narrowing its diameter and facilitating the assembling. SOLUTION: A curved part 4 formed of the curving device is provided with a plurality of joint rings 16, two operating wires 15 and two connecting wires 14. The joint ring 16 is provided with an annular part 21 having a pair of projecting parts 25 with swinging fulcrums in point symmetrical positions, a pair of wire connecting parts 22 provided in the outer circumference of the annular part 21 to receive the connecting wires 14 along the axial direction of the annular part 21, and a pair of through-holes 23 axially penetrating through the annular part 21. The joint rings 16 are aligned in the axial direction with clearances (g) based on the projecting parts 25 formed between the respective ones. The operating wires 15 are passed through the respective through-holes 23 aligned axially and the connecting wires 14 are passed through the respective wire connecting parts 22 aligned axially to be connected to the respective wire connecting parts 22.
