An autoinjector including a syringe, a driver for driving the plunger of the syringe and a stabilizing adaptor for holding the injector on the skin of a patient is provided. The stabilizing adaptor has an adhesive base with a long axis to short axis ratio of at least 1.5 to 1. The syringe is orientated with its axis at an angle of between 60 and 120 degrees to the base during operation of the autoinjector.

Embodiments of the present disclosure provide a device for determining a location of a blood vessel and a method thereof. The device includes a plurality of sensors, a processor, and an indicating device. The plurality of sensors may detect pressure values at a plurality of skin locations in contact with the plurality of sensors. The processor may determine the location of the blood vessel based on the pressure values. The pressure value at the skin location corresponding to the location of the blood vessel is greater than the pressure values at both sides of the skin location in a direction perpendicular to a direction of the blood vessel. The indicating device may indicate the location of the blood vessel.

A medical device that can confirm a predetermined portion in a medical instrument implanted for use in a body. A medical instrument includes a main body part, and a medicinal solution container installed in the main body part. A notification part includes a plurality of light emitting portions that emit light by use of power received by a power receiving part to notify that a predetermined state is reached, when a relative positional relation between a power transmission part and the power receiving part reaches the predetermined state by moving the power transmission part, and a soft part into which an injection needle is inserted, the plurality of light emitting portions are arranged along an outer edge of the soft part. A first coil is a coreless coil disposed to have an inner diameter larger than an outer diameter of the medicinal solution container.

This invention relates to a medical device (20, 40, 60) for use in aiding the successful placement of a needle tip in a blood vessel. The medical device comprises a resiliently deformable collapsible body (21) defining a pressure chamber therein. The body further comprises a port (29) for engagement of a hub of a needle, the port defining a fluid passageway from the exterior of the body to the interior of the pressure chamber. The device further comprises means to generate an audible noise (31, 41) upon expansion of the collapsible body from a collapsed configuration to an expanded configuration. In this way, as the tip of the needle enters the lumen of the blood vessel, the collapsible body is configured to transition from a contracted to an expanded configuration, thereby causing the auditory cue. This auditory cue indicates to the medical professional that the tip of the needle is in the lumen of the blood vessel.

The present disclosure provides a device and a method for cooling living tissues for a medical purpose and other purposes. The cooling device comprises: a container configured to accommodate a cooling medium and thermally coupled with the cooling medium by directly contacting the cooling medium; a cooling generator configured to be thermally coupled with the container by a direct contact and thereby to provide cooling energy to the cooling medium; and a heat sink dissipating heat from the cooling generator, the heat sing being configured to be spaced apart from the cooling generator and to be thermally coupled with the cooling generator without a direct contact with the cooling generator.

Insertion devices, systems, and methods for inserting a needle into a target tissue in an individual in need thereof are disclosed herein. Also disclosed herein are needle cartridges comprising a needle, a plate, and a needle holder. Also disclosed herein are methods of introducing a catheter into a target tissue in an individual in need 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.

A vein imager includes: a housing with first and second portions respectively proximate to first and second ends of the imager; a first light source that emits a first wavelength; an optical detector responsive to the first wavelength and which converts a received vein image into a signal; a second light source that emits a second wavelength; one or more buttons protruding from the housing; and at least one exit opening in the housing for emission of light from the light sources. The first housing portion houses the light sources, the optical detectors, and includes the exit opening. The second housing portion, which houses a battery, is narrower than the first portion to be hand-holdable permitting single-handed lifting and use of the imager, which single-hand lifting and use does not cover the exit opening, and simultaneously permits actuation of the one or more buttons while holding the second housing portion.
