An injection apparatus, including: a needle configured to be inserted into a tissue; a light source to deliver light to the tissue to generate reflected light; a detector to detect the reflected light from the tissue; a processor coupled to the detector and configured to: analyze the reflected light from the tissue to identify a tissue type associated with the reflected light, and provide an output to a user based on the identified tissue type.

A device for performing injections in a patient includes a syringe holder with a needle guard, a cannula extending from the syringe holder, a needle slidably disposed over the cannula, and a slider on the syringe holder. The cannula has a blunt tip and a cannula length, and the needle has a sharp tip and a needle length that is shorter than the cannula length. The slider is coupled with the needle and is configured to slide the needle along the cannula from an extended position, in which the sharp tip of the needle is located at or immediately adjacent the blunt tip of the cannula, to a retracted position, in which the sharp tip is housed within the needle guard of the syringe holder.

Embodiments include systems, methods and devices for the percutaneous delivery of therapeutic agents to tendons, ligaments and muscle. Certain embodiments include a device comprising a needle-catheter based delivery system with adjustable characteristics to allow a clinician to control the angle and depth of needle and/or catheter deployment to a desired location. System embodiments may include a controller unit where a clinician can adjust the axial position depth and location of needles and/or catheters.

A device for introducing a medicament 5 into a patient comprises a cannula 8 having an inlet end 12 for the medicament and a discharge end 14 for the medicament and a blood flow passageway 20 that provides a visual indication that the discharge end of the cannula is in a blood vein.

Syringe assemblies including a syringe pre-equipped with an integral liquid drug administration device for enabling administration of liquid drug contents and a drug vial adapter for telescopic mounting on a drug vial containing liquid drug contents. The drug vial adapter is initially mounted on the syringe and is intended to be manually detached therefrom to expose the integral liquid drug administration device. The syringe includes a flow control member having an initial flow path position for enabling filling the syringe with liquid drug contents from the drug vial and a final flow path position for enabling administration of liquid drug contents. Detachment of the drug vial adapter from the syringe urges the flow control member from its initial flow path position to its final flow path position.

A medical syringe having a forwardly projecting needle that is selectively retractable following use and also having a specially configured plunger handle and thumb cap that cooperate to form a concave pressure application surface (CPAS). The concave pressure application surface at the rear of the plunger handle enables the subject medical syringe to achieve functional advantages, each with an associated therapeutic benefit, that are not achieved with use of the prior art devices.

An injection apparatus, including: a needle configured to be inserted into a tissue; a light source to deliver light to the tissue to generate reflected light; a detector to detect the reflected light from the tissue; a processor coupled to the detector and configured to: analyze the reflected light from the tissue to identify a tissue type associated with the reflected light, and provide an output to a user based on the identified tissue type.

The present invention relates to a syringe, and more particularly, to an apparatus obtained by improving an 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 a conventional syringe to more smoothly perform suction of the liquid medicine, thereby maximizing user's convenience and marketability of the product, and further configured to forcibly close the suction flow passage upon injection of the liquid medicine.

A needle structure for injecting a filler and monitoring a blood backflow situation simultaneously includes a needle, a housing and a partitioning member. The needle includes a needle chamber and a needle opening connected to the needle chamber. The housing includes a housing chamber and a housing opening connected to the housing chamber, and the housing chamber is connected to the needle chamber to form a needle housing chamber. The partitioning member is disposed in the needle housing chamber. The needle housing chamber is separated into a first chamber and a second chamber by the partitioning member. The needle opening is separated into an injection opening and a blood backflow opening by the partitioning member. The first chamber is connected to the injection opening, and the blood backflow opening and the housing opening are connected by the second chamber.
