A deployment device for deploying a transcutaneous sensor in accordance with an embodiment of the present technology includes a housing including a plunger, a frame, and a cap. The deployment device further includes a spring and a carrier within the housing. The frame defines a deployment window through which the carrier is configured to move the transcutaneous device into contact with a target surface of a subject. This can occur at least partially in response to the frame moving in a second direction relative to the plunger, the second direction being opposite the first direction. The deployment device also include a stop that, when engaged, is configured block separation of the cap from the plunger, thereby enabling the spring to be removed from the housing. The stop is configured to disengage at least partially in response to the frame moving in the second direction relative to the plunger.

The present invention relates to adaptor (30) for a drug delivery device having a reservoir (12) and a longitudinal tip (20), the adaptor (30) comprising a distal part defining a connecting ring (31) intended to receive a connector, and a proximal part defining a mounting ring (33) having an inner surface (34), the mounting ring (33) being shaped and configured such that, when the adaptor (30) is mounted around the longitudinal tip (20) of the drug delivery device, at least one annular space (38) is created between said inner surface (34) of the mounting ring (33) and said outer surface (20a) of the longitudinal tip (20), said at least one annular space (38) being able to accommodate an adhesive layer (40) in order to bond said adaptor (30) to said longitudinal tip. The invention further relates to a drug delivery device comprising such an adaptor.

An auto-injector device includes a pre-filled syringe including a container and a stainless steel needle adhered to the container with at least one of a urethane acrylate adhesive or a urethane methacrylate adhesive. The container is filled with at least 1 mL of a pharmaceutical composition comprising epinephrine, a buffer, and water, where the pharmaceutical composition has a pH ranging between 3 and 4. The auto-injector device also includes a firing mechanism that expels about 0.3 mL of the pharmaceutical composition from the container in less than 0.5 seconds during a single injection.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

A drug injection syringe includes an injection needle assembly and a syringe body. The injection needle assembly includes an injection needle, a needle hub, an elastic body, and a fitting sleeve. The fitting sleeve accommodates the needle hub and the elastic body and has a fitting hole formed in a female taper shape. The syringe body includes an outer tube and a drug discharge tube formed in a male taper shape. The syringe body is attached to the injection needle assembly by pushing the drug discharge tube into the fitting hole by a press fitting. The elastic body couples the drug discharge tube and the injection needle in a liquid-tight manner by compressively deforming, due to the press fitting, at a protruding portion disposed on a periphery of the pocket and stretching against an inner wall of the fitting hole.

A method of using a medicine injection device including a syringe filled with a medicine; a needle tube having a needle tip for puncturing the skin; a flange-like skin contact portion that is disposed in a manner so as to cover an area surrounding the needle tube and makes contact with and/or faces the skin when the living body is punctured with the needle tube; and an absorption part that is disposed in the skin contact portion of the needle hub. The method includes removing air from the medicine injection device prior to injection of the medicine, whereby medicine spilled from the needle tip is caught in the skin contact portion; the absorption part absorbing the spilled medicine staying in the skin contact portion; positioning the skin contact portion adjacent the skin; puncturing the skin with the needle tip; and injecting medicine from the needle tip into the skin.

A needle assembly for a hypodermic syringe is disclosed herein. In various aspects, the needle assembly includes a hub and a needle. A bond secures the needle to the hub, and the bond is configured to break allowing the needle to be withdrawn entirely from the hub upon application of a selected axial force to the needle, in various aspects. The axial force may be less than the tensile strength of the needle. Related methods of use of the needle assembly apparatus are disclosed herein. This Abstract is presented to meet requirements of 37 C.F.R. 1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and the related methods disclosed herein or to delineate the scope thereof.

The present invention relates to a method for extracting aldehydes from the adhesive used for gluing needles to syringes, and to a method for determining the aldehydes releasable from said syringes, be fore or after such a treatment. In particular, the present invention relates to a method for extracting residual aldehydes from syringes comprising a step of treating said syringes at a temperature higher than or equal to 50? C., preferably higher than or equal to 90? C., wherein said treatment step is preferably carried out in an autoclave at a temperature higher than 90? C. and at a pressure higher than atmospheric pressure.
