The invention relates to a method for connecting a first component, in particular a lancing means, to a second component, in particular a syringe body, in order to produce a product for medical or cosmetic purposes, by means of adhesion, having the following steps: (a) providing the first and the second component; (b) tempering at least one first contact surface of the first component and/or at least one second contact surface of the second component to a temperature T1; and (c) applying an adhesive to at least one portion of the first contact surface and/or to at least one portion of the second contact surface, wherein the adhesive is at a temperature T2, wherein temperatures T1 and T2 differ only by a tolerance deviation, wherein the tolerance deviation is at most 10° C.

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 needle-equipped outer cylinder includes: a needle tube; a joining member comprising: a needle tube accommodation hole that accommodates a proximal end side portion of the needle tube and penetrates the joining member from a distal end of the joining member to a proximal end of the joining member, and a joining outer peripheral portion provided on an outer peripheral portion of the needle tube accommodation hole; and an outer cylinder member comprising: a distal end joint that comprises an inner cavity that receives the joining outer peripheral portion of the joining member from a distal end side, and a projection located at a proximal end portion of the inner cavity and projecting into the inner cavity. The joining member comprises, at a proximal end portion of the joining member, an abutment portion that abuts the projection of the outer cylinder member.

Method for coating a glass syringe body for a hypodermic pre-filled glass syringe, wherein at least one emulsion and/or one solution containing at least one layer-forming substance is applied to at least one inner surface of the hypodermic pre-filled glass syringe, which defines an axial direction, wherein at least a partial surface of the inner surface in a syringe cone of the pre-filled glass syringe is subsequently exposed to a plasma, wherein a negative pressure source is arranged in relation to the syringe cone in the axial direction opposite the atmospheric-pressure plasma source, wherein a negative pressure of less than atmospheric pressure is provided by means of the negative pressure source.

A needle-bearing hub for a pen needle is provided with a distal patient-facing side having an enlarged surface for contact with the subject's skin. The enlarged surface is provided with a radius of curvature that increases the likelihood that the needle reaches full injection depth when an injection is performed at an inclined angle with respect to the surface of the skin and with to the desired depth less discomfort to the patient.

The present invention relates to a filtering syringe, and more particularly, to an apparatus obtained by improving a syringe provided with a filter means for filtering foreign substances such as glass fragments of an ampoule, so as to prevent an injection needle or an injection flow passage from being contaminated with the foreign substances while allowing a liquid medicine to be smoothly sucked with a smaller force. The filtering syringe is configured such that the injection needle or the injection flow passage is isolated from the suction flow passage which is upstream of the filter means and in which the foreign substances may remain together with the liquid medicine, thereby allowing the liquid medicine to be sucked with a force less than that required for a conventional syringe and thus maximizing user's convenience and marketability of the syringe.

The purpose of the present invention is to provide a needle hub unit and the manufacturing method thereof, that enables injection with the least possible waste of a medicinal solution. The present invention is provided with a needle hub, a recess provided in the needle hub and into which a tip portion of an injection cylinder is inserted, an elastic body internally provided in the recess and fills a gap between the tip of the injection cylinder and the recess, and an injection needle inserted into the needle hub and penetrating through the elastic body, whereby the injected medicinal solution passes only through the injection needle, thus the remaining of the medicinal solution in the needle hub is prevented.

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 hypodermic interface assembly includes a cannula and a hub. The hub is defined by a first portion and a second portion. The second portion of the hub is breakably-connected to the first portion of the hub. The cannula is joined to the second portion of the hub. The second portion of the hub is defined by an outer head surface portion having a first geometry. The second portion of the hub also includes an outer neck or groove surface portion having a second geometry. The first geometry of the outer head surface portion is greater than the second geometry of the outer neck or groove surface portion.

A hypodermic interface assembly is disclosed. The hypodermic interface assembly includes a hub, a cannula, and a cannula carrier. The cannula carrier is non-removably-connected to the cannula. The cannula carrier is controllably separable from the hub.
