Systems and methods encourage users to rotate injection sites and avoid lipodystrophy. Sleeves and/or lost-tooth gear dials and/or microswitches in or on injection pens or their caps, on vials, and on other portable devices manually adjust an indicator before or after an injection to show a current or next injection site in accordance with a site rotation plan. Injected medicine packaging and related printed indicia encourage site rotation. Optical devices employing optical mouse or projection technology help locate and/or distribute injection sites within a body area. A mobile phone app tracks injections and locations to select next injection site, and can use imaging to locate a target injection site and optionally diagnose lipodystrophic conditions and record them. Tactile and print media educational tools are presented to help users palpate and identify lipos in body areas having injection sites.

A medical apparatus in which the measurement of an electrocardiogram and the detection of blood leakage that may occur if an accessing unit comes off the patient can be performed accurately without fail, and with which the efficiency in the operation to be performed before the treatment can be improved. A medical apparatus includes a blood purification device including an accessing unit formed of a venous puncture needle stickable into a patient, electrocardiogram-measuring devices closely attached to a skin of the patient and being capable of measuring an electrocardiogram of the patient, and a blood-leakage-detecting device attached to a position near the accessing unit and being capable of detecting blood of the patient that may leak from the accessing unit. The medical apparatus further includes an integrated detecting device provided as a unit including the electrocardiogram-measuring device and the blood-leakage-detecting device.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

The present invention relates to medicament injection devices (100). A cartridge (600) with a septum and a needle unit (500) having front and rear needles (510, 520) are configured for relative movement from a state where the septum is sealed to a state where the septum is pierced by the rear needle (520). The injection device (100) may include a needle shield (350) and be configured for piercing the septum by the rear needle (520) when the front needle (510) is operated relative to the needle shield (350). The injection device (100) may also include a damping mechanism configured for limiting the speed of movement of the cartridge relative to the needle unit. The injection device (100) may also include an indicator generating a signal when a piston driver has travelled the complete stroke length, wherein the indicator has a deflection element that is deflected prior to or during movement of the cartridge relative to the housing.

A method for detecting a limit of use of a medical device is presented having the steps of starting a timer of a medical device when the medical device is used for the first time, detecting the limit of use of the medical device and indicating the limit of use of the medical device. The limit of use is reached when at least one of a first criterion and a second criterion is met, wherein the first criterion is that the timer reaches or exceeds a time limit and wherein the second criterion is that at least one operation of a drive train of said medical device reaches or exceeds a limit.

Sensor assembly comprising a first rotary sensor part with a plurality of individual electrically conducting sensor areas arranged in a pattern, a second rotary sensor part arranged rotationally relative to the first portion, the second part comprising a plurality of contact structures adapted to be in contact with conducting sensor areas on the first sensor rotary part. The contact structures are configured to engage and connect different sensor areas as the first and second part of the rotary sensor rotate relative to each, the created connections being indicative of a rotational position between the first and second portions. One of the contact structures is an actuatable contact structure being axially moveable relative to the first portion and having a connected position in which the actuatable contact structure is in contact with a sensor area and a disconnected position in which the actuatable contact structure is not in contact with a sensor area.

This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that it cannot be reused. Such single use caps and covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing the incidence of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits its including such caps and covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using such caps and covers, are also described.

An infusion pump assembly includes a reservoir assembly configured to contain an infusible fluid. A motor assembly is configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly. Processing logic is configured to control the motor assembly. A primary power supply is configured to provide primary electrical energy to at least a portion of the processing logic. A backup power supply is configured to provide backup electrical energy to the at least a portion of the processing logic in the event that the primary power supply fails to provide the primary electrical energy to the at least a portion of the processing logic.

A portable liquid medicine administration device for continuous or intermittent administration of a liquid medicine into a living body includes: a liquid medicine administration device main body filled with the liquid medicine; and a cradle to which the liquid medicine administration device main body is attachable and detachable. The liquid medicine administration device main body includes: an alarm unit configured to output an alarm on a basis of a notification event occurring while the liquid medicine administration device main body is attached to the cradle; and an alarm control unit configured to stop the alarm on a basis of a change occurring in a relative position between the cradle and the liquid medicine administration device main body.
