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 syringe includes a syringe body, a syringe cone having a distal opening, and a connection arranged in the region of the syringe cone, wherein the syringe body includes a first material and the connection includes a second material, and wherein the first material is different from the second material and the second material is a softer material than the first material.

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.

The present disclosure provides medical devices, particularly medical grade needles with removable tips, as well as methods of needle tip installation and removal, and devices therefor. Needle tip installation and removal devices may include needle tip installation and removal tools and kits, including hand held and manipulated tools that facilitate the installation and removal of needle tips, particularly on vascular access port needles. Such installation and removal devices may provide more expedient hook up of the access port for the therapy. Also, the installation and removal of the needle tips may be conducted in a more sterile manner.

A securing device for an injection device which receives a syringe with a proximal end portion having a radially outwardly projecting flange, has a body with proximal and distal end portions, an opening for accepting the syringe, an outer surface, and a proximal end surface for contacting a distally-facing surface of the flange when the syringe is advanced distally, preventing further advancement. A securing arm includes a free end; a base end fixed to the outer surface; a first portion extending radially outwardly from the base end to permit the flange to pass; and a second portion extending radially inwardly in a rest position, contacting the flange as the syringe is advanced. The securing arm is elastically flexible to allow the free end to move radially outwardly, allowing the advancing flange to pass, and is biased to the rest position to secure the flange and the syringe against proximal movement.

The present invention relates to a low dead space hub and a needle coupled to said hub, the dead space of which has a storage capacity of less than about 0.0190 milliliters.

The present invention relates to an opening and liquid supplying system (100) for pre-filled containers (10, 30) equipped with a supplying end, comprising a coupling element (20), connecting means (6) movable from a first position to a second position, and movable protection means (9); the coupling element (20) has an end (27) closed and suitable for being punched, and first guiding means (21) for guiding the movement of the connecting means (6) movable from the first position, close to the closed end (27), to the second position, apart from such end, and vice versa; the connecting means (6) have engaging means (7) for engaging with the protection means (9) so as to move integrally along a second degree of freedom, different than the first degree of freedom, and first matches (11) for the first guiding means (21). The invention relates also to a respective pre-filled container equipped with such system and the method for realize them.

The present invention relates to a syringe, and more particularly, to an apparatus obtained by improving a conventional syringe formed with an injection flow passage including an injection needle, so as to share a portion of the injection flow passage except the injection needle or to form a suction flow passage completely independent of the injection flow passage, thereby further smoothing suction of a liquid medicine. The syringe is configured such that the separate suction flow passage bypassing the injection needle is formed in the conventional syringe to more smoothly perform suction of the liquid medicine, thereby maximizing user's convenience and marketability of the conventional syringe, and further configured to forcibly close the suction flow passage upon injection of the liquid medicine.

A disposable syringe set includes a syringe barrel in which a medicinal fluid inlet is formed and a plunger is fitted and coupled to an opening at the other side; a first screw-coupling portion formed on an outer circumference of the medicinal fluid inlet; a syringe needle hub in which a syringe needle is coupled to one end and an inner side at the other end is fitted and coupled to the outer circumference of the medicinal fluid inlet; and a second screw-coupling portion formed on an inner circumference of the syringe needle hub and configured to be coupled to the first screw-coupling portion. The first screw-coupling portion is formed as a female-thread-type coupling portion whose diameter is smaller than a reference diameter of the medicinal fluid inlet. The second screw-coupling portion is formed as a male-thread-type coupling portion configured to be coupled to the female-thread-type coupling portion.
