The pushing member is configured to be movable relative to the needle from inside the needle toward the opening.

Actuating components and related methods are generally disclosed. Certain embodiments comprise an actuating component associated with a plurality of microneedles (e.g., for administering a therapeutic agent to a subject). In some embodiments, the actuating component may be administered to a subject such that the plurality of microneedles are deployed at a location internal to the subject (e.g., in the gastrointestinal tract). The actuating component may be contained within, in some embodiments, a capsule (e.g., for oral administration to a subject). In some embodiments, the actuating component has a pre-deployment configuration in which the plurality of microneedles have a first orientation and a deployed configuration in which the plurality of microneedles have a second orientation, different than the first orientation.

The needle assembly (2) further including a plurality of integrated peel tabs (70) each detachably connected to one of the plurality of needle posts (24), wherein in a first position of the needle assembly (2), the plurality of needles (34) is disposed in the needle assembly septum (60), and in a second position of the needle assembly (2), one of the plurality of integrated peel tabs (70) is drawn out of the housing (16) to cause a selected needle (40) of the plurality of needles (34) to pierce the needle assembly septum (60) and be exposed for medication delivery.

A skin treatment device is provided, which includes a needle frame in which a front end outlet of a needle that penetrates an inside thereof projects toward a front thereof, a rear end inlet of the needle is open to an outside of a rear surface thereof, and a stepped partition wall is provided in a closed shape on the outside of the rear surface thereof; a needle cover having a space portion formed on a rear thereof toward an inside thereof, a needle guide portion formed on a front surface thereof; a contact PCB configured to receive a power that is supplied from a power supply device; and a needle hub having an insertion portion formed in a front thereof toward an inside thereof.

The invention relates to a needle delivery device comprising a device body; one or more skin pinching members attached to the device body, the skin pinching members being moveable to pinch a longitudinal fold of skin of a patient. The device also comprises a drive mechanism configured to drive a needle out of the device body and along a needle path into the longitudinal fold of skin pinched between the pinching members, and subsequently withdraw the needle, the needle path extending substantially parallel to the surface of the patient.

An injection needle includes a first needle portion defining a first outer diameter, a second needle portion defining a second outer diameter that is smaller than the first outer diameter, the second needle portion having a tip configured to penetrate a soft tissue. Importantly, the first end of the second needle portion is positioned substantially inside and coupled to an inner surface of the first needle portion adjacent an angled section that is positioned adjacent a distal end of the first needle portion. In addition, the first and second needle portions may be crimped or pinched together into a unitary construction that still allows a pharmaceutical to pass therethrough.

Provided are a medicine injecting tip, which injects a medicine into a hole in a skin formed by a needle while invading the needle to a preset depth of a deep portion of the skin, a hand piece equipped with the medicine injecting tip, and a skin treatment device using the medicine injecting tip. The medicine injecting tip includes a cylinder, a plunger that reciprocates downward and upward, and has a first space and a second space formed inside the cylinder, and a needle disposed in the plunger and disposed in the second space of the cylinder. The needle is inserted into a skin and a negative pressure state is formed in the second space when the plunger moves downward, and the needle is discharged from the skin and a positive pressure state is formed in the second space, when the plunger moves upward.

The present invention provides a microneedle stamp device for injecting liquid medicine; a carboxy cartridge provided in the main body portion; a liquid medicine storage portion provided outside the main body portion and connected to the carboxy cartridge; a needle portion connected to the carboxy cartridge and the liquid medicine storage portion; a power portion provided in the grip; a connection portion configured to connect the carboxy cartridge to the needle portion; and a contact plate provided at the contact end of the main body portion, wherein, when the contact plate comes into contact with the skin of the treatment subject, the contact plate slidingly moves to the inside of the contact end to apply an external force to the power portion to operate the power portion to supply the liquid medicine and the carbon dioxide to the needle portion.

Proposed is a device for automatically operating a stamp-type fluid injector having fine needles for hair loss care and treatment. A hole is formed at the center of a cover coupled to the lower portion of an outer case such that an outer cap is moved up and down in the hole by a motor. An inner cap elastically operated by a spring is disposed under the outer cap, a flexible cap is disposed in the inner cap, and a fluid injector is simply inserted into and separated out of the flexible cap through the hole of the cover. Accordingly, it is possible to uniformly and continuously tap the scalp by automatically moving up and down a fluid injector by operating the motor. Further, a fluid injector can be more conveniently used, as compared with when it is manually used.

The present invention provides a drug delivery device (2, 3; 102) for sequential administration of substances, comprising a first variable volume reservoir (40a; 140a) holding a first substance and comprising a first outlet (41 a, 141 a) and a first displaceable wall (43a; 143a), a second variable volume reservoir (40b; 140b) holding a second substance and comprising a second outlet (41 b; 141 b) and a second displaceable wall (43b; 143b), a first wall actuation structure (65a, 70a, 75a, 77a; 177a) activatable to move the first displaceable wall (43a; 143a) and thereby expel a dose of the first substance through the first outlet (41 a; 141 a), a second wall actuation structure (65b, 70b, 75b, 77b; 177b) activatable to move the second displaceable wall (43b; 143b) and thereby expel a dose of the second substance through the second outlet (41 b; 141 b), and a drive structure (90; 190) for activating the first wall actuation structure (65a, 70a, 75a, 77a; 177a) and the second wall actuation structure (65b, 70b, 75b, 77b; 177b). The drive structure (90; 190) performs a predetermined movement during one sequential administration of the first substance and the second substance, the predetermined movement comprising a first part movement followed by a second part movement, and is configured to activate the first wall actuation structure (65a, 70a, 75a, 77a; 177a) during the first part movement and to activate the second wall actuation structure (65b, 70b, 75b, 77b; 177b) during the second part movement.
