Abstract:
Fluid delivery devices and means for engaging components therein are described. The devices may include a plunger positioned within a reservoir and connected to a non-rotating drive screw and a drive nut capable of engagement with the drive screw, where, upon engagement of the drive nut with the drive screw, rotation of the drive nut linearly displaces the drive screw. The devices may also be skin-securable and comprise a reusable part and a disposable part wherein, upon connection of the reusable part and the disposable part, the drive screw engages with the drive nut such that rotation of a motor and/or one or more gears results in rotation of the drive nut and linear displacement of the drive screw.
Abstract:
Disclosed is a skin adherable device for delivering therapeutic fluid into a body of a patient. The device includes a monitoring apparatus, a dispensing apparatus, and a tip for delivering the therapeutic fluid into the body of the patient and for monitoring bodily analyte in the body of the patient. The dispensing apparatus may continuously deliver the therapeutic fluid to the body of the patient and the monitoring apparatus may continuously monitor bodily analytes of the patient.
Abstract:
Techniques and devices are described for allowing a diabetes patient to safely disconnect an insulin infusion system device for a time period. In one aspect, the techniques and devices can be implemented by receiving a maximum blood glucose amount, a minimum blood glucose amount, and a contemplated disconnection time; receiving a current blood glucose amount of the user; determining an expected increase in blood glucose of the user based on the contemplated disconnection time, an insulin sensitivity of the user and a contemplated basal insulin dose; validating the contemplated disconnection time based on at least one of the expected increase in blood glucose, the maximum blood glucose amount, and the minimum blood glucose amount; and, administering a therapeutic action to the user based on the validation of the contemplated disconnection time.
Abstract:
An apparatus and a method for use with a device for delivery of a therapeutic fluid into a body of a patient and/or for sensing of a bodily analyte are disclosed. The apparatus is adapted for accommodating at least one subcutaneously insertable element and at least one penetrating member for penetrating the skin of the patient. The apparatus includes a protective member having an elongate body from which the subcutaneously insertable element and the penetrating member can be protracted to penetrate the skin of the patient and into which the penetrating member can be retracted subsequent to the penetrating, thereby retaining the subcutaneously insertable element in the body of the patient.
Abstract:
Disclosed is a system to deliver insulin to a user's body. The system includes a dispensing unit to deliver the insulin to the body, and a control mechanism to control delivery of basal insulin according to a predetermined basal infusion pattern, the basal infusion pattern selected from a plurality of predetermined basal infusion patterns. In some embodiments, selection of the basal infusion pattern may be based on one or more personal characteristics of the user.
Abstract:
An apparatus (10) of the skin-patch type for delivery of a therapeutic fluid to the body of a patient are provided. The apparatus includes a reusable dispensing unit (100) having a driving mechanism and a pumping mechanism for pumping the fluid to the body of the patient and a disposable unit (200) with a collapsible reservoir (220) tillable with the therapeutic fluid for delivery thereof to the body of the patient.
Abstract:
Systems, methods and apparatuses for delivering therapeutic fluid to the body of a patient are disclosed. The apparatus includes a dispensing unit (10) having a driving mechanism (120), a pumping mechanism (110), a reservoir (220) containing therapeutic fluid, and an outlet port (210). The driving mechanism causes the pumping mechanism to positively displace therapeutic fluid within the reservoir for delivery of therapeutic fluid to the body of the patient via the outlet port.
Abstract:
Medical devices and methods for delivering therapeutic fluids transcutaneously to a body of a patient via a fluid delivery device and an adapter is provided. A Luer slip connector is provided at a first connecting end of the adapter. A therapeutic fluid container is connected with the second connecting end such that the container's neck is received in the second connecting end and a hollow penetrating member provided in the adapter punctures the septum of the container to admit the therapeutic fluid into a needle-less syringe from the container. After, fluid emerges from the tip of the penetrating member, the second connecting end of the adapter is attached to the fluid delivery device, thereby filling the reservoir with the fluid and pushing the syringe plunger forward to inject fluid into reservoir.
Abstract:
Fluid delivery systems, methods and devices for delivering a therapeutic fluid to the body of the patient are disclosed. A fluid delivery device (100) for delivering fluid to the body of the patient includes a housing having an upper wall (534) and a lower wall (536), wherein the upper wall includes an upper opening (116) and the lower wall includes a lower opening (540), a well-arrangement mechanism (510) configured to be disposed inside the housing and between the upper wall and the lower wall and including a tubular member (322) having a bore (326), wherein the bore is configured to be disposed between the upper opening and the lower opening, and a penetrating cartridge (662) for delivery of therapeutic fluid to the body of the patient, wherein the penetrating cartridge is configured to engage the bore following its insertion through the upper opening and the lower opening, wherein therapeutic fluid is configured to be delivered through the tubular member into the penetrating cartridge into the body of the patient when the penetrating cartridge engages the bore.
