The specification also provides a method of controlling an injection device (100) including a needle insertion mechanism (111); a medicament delivery arrangement (123) configured to cause injection of a medicament into a patient; and a cavity (102) having an opening (103) for receiving a key device (104), the method comprising: responding to detecting the presence of the key device in the cavity by triggering operation of the injection device.

A supplementary device configured to be releasably attached to a drug delivery device. The supplementary device comprises a housing having a channel configured to slidably receive the drug delivery device; a first alignment feature to ensure a specific alignment of the supplementary device relative to the drug delivery device and restrict rotational movement of the supplementary device around a drug delivery device; and a second alignment feature to prevent sliding movement of the supplementary device relative to the delivery device once attached thereto. The second alignment feature comprises a moveable securing member biased towards the drug delivery device, and a release member operable to move the securing member out of engagement with the drug delivery device.

In order to address a common need for cost efficient capturing of data relative to dosage and administration time in self-medication schemes, the present disclosure proposes an apparatus with an accessory and an injection device, wherein the accessory attaches and detaches to the injection device, the accessory housing a control unit; and the injection device includes a passive electronic arrangement and the control unit is configured to use the passive electronic arrangement to determine information correlating to a dose of medicament injected.

A cassette for use with an injector has a housing, and a cassette identification arrangement (cassette ID) defining a code containing information about the cassette that is detectable and decipherable by an injector. The cassette may further have a sleeve movably disposed within the housing, for holding a drug container, and a locking arrangement for interlocking the sleeve with the housing. The cassette may further have an aperture in the housing, and a cassette cap for removing a needle shield of the drug container. The cassette may have an anti-bending structure to prevent bending or flexing of the cassette cap. The injector may have a processor for controlling operational parameters of the injector and a detector communicatively coupled with the processor for detecting and communicating the cassette ID to the microprocessor to decipher the code defined therein. Also, a method of injecting a drug into a patient with an injector, wherein the sequence of actions performed by the user are controlled. Still further, a method of treating a patient in need thereof wherein a cassette containing a drug is provided and administered to the patient using an injector.

A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution. A cassette control surface may be arranged to have one or more ports that can detect a presence of a liquid, e.g., to identify if a cassette is leaking or has otherwise been compromised.

The disclosure relates to the field of medical instruments, and discloses a control device and method for a ventilation therapy equipment, and ventilation therapy equipment. The ventilation therapy equipment has multiple working modes. The control device includes an identification device used for identifying a type of an accessory of the ventilation therapy equipment; and a controller used for determining and controlling, according to the identified type of the accessory, the ventilation therapy equipment to switch to a working mode corresponding to the type of the accessory. The control device can automatically switch the corresponding working modes according to different types of accessories, and is more convenient and intelligent, so that a lot of time can be saved for a doctor and a patient.

A multi-medicament infusion system (10) for preventing the mischanneling of medicaments may include an infusion pump (12), medicament reservoirs (16A,16B), a multi-channel lumen (18), and an infusion set (20). The medicament reservoirs may be sized and shaped differently such that the medicament reservoirs can only be inserted into the infusion pump in a unique configuration. The multi-channel lumen may include connectors that mate to corresponding connectors on the infusion pump and the infusion set only in a unique configuration. Because the various parts of the multi-infusion system may only be connected in the unique configuration, the expected medicaments may be administered appropriately and channeled to the correct infusion sites.

An improved injection port identification for injection ports implanted under the skin of a patient. The injection port has an x-ray discernable marker allowing for the determination of a pressure rating for the injection port when so implanted. A plurality of concurrent visual, RF, light emitting and sonic means for signaling the port's pressure rating are also employable to provide multiple concurrent affirmations of the port's readiness for high pressure injections.

A method of treating disorders in a human or animal subject may include heating a material containing a compound to a first temperature to form a heated volume of the material. The method may additionally include heating the heated volume to a higher second temperature to form a dose of vapor including the compound. The method may also include administering the dose of vapor to the subject to treat disorders such as pain. The method may further include pre-heating the material to a preliminary temperature prior to the heating to the first temperature. The heating and pre-heating may be performed with a capsule including two covering layers, each including an electrically conductive material, configured to hold the material therebetween and to generate heat by resistive heating.
