A dual chambered syringe includes: an inner barrel defining a first inner chamber, the inner barrel having an apertured stopper at its distal end, the inner barrel being open at its proximal end; a shaft adapted to fit within the inner barrel, the shaft having a distal end which is engageable with the aperture of the stopper; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the stopper; an outer barrel concentric with the inner barrel defining a second inner chamber, the outer barrel having a distal end for receiving and dispensing fluids and a proximal end into which the distal end of the inner barrel is insertable into the second inner chamber; the apertured stopper engages the second inner chamber of the outer barrel and selectively prevents or permits the passage of fluids between the outer barrel second chamber and the inner barrel first chamber; the inner barrel having an engageable surface on its outside surface; and, the outer barrel having operatively associated therewith an engaging device for selective engagement and disengagement with the engageable surface on the inner barrel.

In some examples, a tissue compression device includes a base including a major surface configured to engage a dorsal surface of a hand of a patient, a flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand when the dorsal surface of the hand is engaged with the base, and an expandable member mechanically connected to the flexible backing. The expandable member is configured to be positioned over an ulnar region of the patient when the palmar surface of the hand is engaged with the flexible backing and the dorsal surface of the hand is engaged with the base, such that inflation of the expandable member may apply pressure to tissue near the ulnar artery of the patient.

There are provided an intradermal needle, a packaged article, and an injection device. The intradermal needle includes: a tubular needle that has a needle tip capable of puncturing a living body; a needle hub that holds the tubular needle; a flange part that extends in a flange shape from the needle hub; and a ring projection that extends toward a leading end of the flange part and is formed in a cylindrical shape to surround the tubular needle. The flange part has a cut portion formed by partially cutting to achieve downsizing of the flange part.

The present invention relates to the intravenous injection aid for indicating vein, comprising: a compression strap; a binding means disposed at the opposite ends of the compression strap; a near-infrared lamp disposed at the compression strap; and a controller disposed on the compression strap for controlling the near-infrared lamp. The present invention as mentioned above may not only indicates vein with high visibility but also keep the vein from swaying or moving even during intravenous injection, so the intravenous injection can be carried out safely and efficiently.

A drug delivery device includes a housing, a cartridge received within the housing, with the cartridge configured to receive a medicament, a drive assembly received within the housing and configured to engage the cartridge and dispense medicament from the cartridge, and a needle actuator assembly received within the housing, with the needle actuator assembly including a patient needle configured to pierce a patient's skin. A bottom surface of the housing defines a port interface configured to receive an implanted injection port.

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.

Provided herein are systems and methods for monitoring one or more health or physiological parameters in a subject. The systems and methods may comprise a patch coupled to an injector. Data may be transmitted to a mobile device or remote server, where the data may be processed. Processed data may be used to inform a subject on a health or physiological condition.

Systems, devices, and methods are provided for transseptal access of septa within a patient. The device can be advanced to a septum, e.g., towards a fossa ovalis. Instead of applying positive pressure to “tent” the septum, a negative pressure is applied to a lumen within a sheath, e.g., within an elongated member slidable within the sheath, via a negative pressure source such as a syringe on the proximal end of the sheath. This results in the septum pulling inward. The sheath employs a stationary needle-like central core component contained within the lumen of the sheath that punctures the septum when the same is pulled passed it by the negative pressure. The stationary needle-like central core component may be hollow and may form a portion of the elongated member or may be coupled to a distal end thereof.

In some examples, a tissue compression device includes a base including a major surface configured to engage a dorsal surface of a hand of a patient, a flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand when the dorsal surface of the hand is engaged with the base, and an expandable member mechanically connected to the flexible backing. The expandable member is configured to be positioned over an ulnar region of the patient when the palmar surface of the hand is engaged with the flexible backing and the dorsal surface of the hand is engaged with the base, such that inflation of the expandable member may apply pressure to tissue near the ulnar artery of the patient.

The present invention has an object to prevent skin from being depressed during insertion of a needle into the skin. A puncture assisting tool (1) includes: a first fixing part (10A) that is fixed to a first region of skin; and a second fixing part (10B) that is fixed to a second region of the skin; the first fixing part (10A) being movable relative to the second fixing part (10B) so as to pull the skin between the first fixing part (10A) and the second fixing part (10B).
