Provided is a device for injecting a fixed quantity of liquid medicine, to which a syringe may be mounted and which may inject the liquid medicine held in the syringe by a fixed quantity due to a user's pushing operation. The device for injecting the fixed quantity of liquid medicine is advantageous in that a user can operate the device with one hand to inject the fixed quantity of medicine into various areas, thus maximizing operability and convenience. Furthermore, the device is advantageous in that it is possible to maximize medicine delivery efficiency even when operated by a person who is not a medical staff not in a hospital but at home.

A blister strip which can be stuck onto the skin, is formed from at least two sheets and has an applicator for applying a medium contained in the blister to the skin, wherein the blister strip includes an upper sheet, with at least one protuberance, wherein the underside of the upper sheet, the underside enclosing the protuberance, is of adhesive configuration. The blister strip has a lower sheet, which covers the lower surface of the blister strip and can be drawn off from the adhesive underside of the upper sheet. The protuberance contains an applicator, separating the protuberance into at least two sub-volumes. Wherein the applicator has at least one opening, which connects two sub-volumes, wherein one sub-volume is located between the applicator and the lower sheet, and wherein at least one sub-volume is entirely surrounded by the inner surface of the protuberance and the applicator, and contains the medium.

A hair growth applicator for promoting the growth of hair follicles by applying hair growth liquid, comprising a handle having an internal chamber for containing said hair growth liquid, said handle having a channel running from said chamber to a distal end of said handle, a tip disposed at said distal end of said handle with a plurality of needles disposed on said distal surface of said tip, said distal surface having an opening, wherein said chamber is in fluid connection with said opening on said distal surface of said tip

The embodiments relate to improved skin quality, health and appearance using a new delivery method and certain bioactive compositions and formulations. The system incorporates microneedle delivery technology with unique compositions and formulations. Such development allows for the pursuit of personalized medicine, or treatment delivery that can expand to remote controlled environment, immediate compounding and ultimate personalization with a state of the art longitudinal data predictive analytics. Certain formulations described herein are unique, combinatory and synergistic. Secured by high-tech proprietary system, there are unlimited potentials using AQT technology including but not limited to 3-D printing of a biodegradable micro chips that can be delivered via injection, AQT or any other possible route.

A syringe assembly (2) that locks a syringe (10) to prevent backflow of medicament, the syringe assembly (2) comprising a syringe (10) including a barrel (12) configured to carry the medicament, a plunger (14) that communicates with the barrel (12), and a plunger head (16) disposed on a proximal end of the plunger (14), and a locking assembly (50) disposed around the barrel (12), wherein the locking assembly (50) prevents the plunger (14) from moving away from the barrel (12) to draw the medicament into the barrel (12).

Apparatus and methods for medicament delivery. The apparatus may include, and the methods may involve, a delivery device for delivering a target amount of the medicament from a distal end of the device. The device may include a rod for moving a plunger that discharges the medicament from the distal end. The device may avoid or reduce deformation of the plunger during the discharge. The plunger motion may be stopped by detent that interacts with the rod. The apparatus and the methods may provide an operator indication of progress of stages of operation. The device may feature triggers corresponding to stages of medicament displacement from the device, such as pre-delivery stages, including priming.

The present disclosure relates to an insertion type drug injection device capable of being inserted into a body for injecting a drug into a skin, including: a main body having an open insert part and formed in a tubular shape having a hollow space therein, a needle assembly formed in the insert part, provided with a plurality of needles, and including a pneumatic port and a drug injection port, and a drug injection pipe inserted into the main body and connected to a drug injection port of the needle assembly, and an air flowing pipe connected to the pneumatic port.

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.

A syringe for dermal regeneration comprises a body comprising inner and outer tubes, a cylinder filled with a first fluid being inserted into the inner tube from behind, and the outer tube being spaced apart from the inner tube and shaped to surround the inner tube such that a fillable space is formed between the inner tube and the outer tube and is filled with a second fluid; an injector coupled to the front portion of the body, the injector comprising a first part, a second part, and a third part; a through-hole formed through one side of the second part of the injector so as to communicate with the fillable space; and a check valve provided in the through-hole so as to block a flow of fluid from the injector to the fillable space and to allow a flow of fluid from the fillable space to the injector.

Various systems and methods for the pressure-regulated transfer of medical fluids are disclosed. The system can include an adapter assembly that connects with a medical container and with a syringe assembly. The syringe assembly can include a first reservoir and a second reservoir. In various embodiments, when the adapter assembly and the syringe assembly are coupled, the first reservoir and the container can exchange regulating fluid and the second reservoir and the container can exchange medical liquid from the medical container.
