A means and a method is disclosed to diminish or eliminate the pain associated with a sharp object penetrating the skin, during such procedures as an injection, biopsy, or deriving a blood sample. To this end, repeated tapping, pressing, or rubbing or vibrating is performed over the skin at or near the site of penetration of the sharp object in conjunction with applying electricity on the skin. The invention discloses a method of using a skin-puncturing means, with enhanced features, to provide local anesthesia at the site of penetration of a sharp object.

A device for reducing the pain associated with an injection, the device comprising: a body configured in use to be positioned around or proximal to an injection site while allowing a user to view the injection site while performing the injection, the body comprising an 5 operative face configured to be placed against the skin of a user; the body having: a stimulus element in the form of at least one protrusion configured to extend beyond the operative face to contact the skin of the user around or proximal to the injection site and stimulate the skin of the user.

An injection apparatus includes a base, an anesthetic holder, one or more vibration motors, and a hollow cylinder. The base includes a bottom surface for placement against a patient's skin, wherein the base includes one or more apertures. The anesthetic holder extends from the base and retains an anesthetic, wherein the holder is in fluid communication with the one or more apertures located on the base. The one or more vibration motors are affixed to the holder. The hollow cylinder includes a first end and a second end, wherein the first end is configured to receive an injecting pen and the second end is located adjacent to the base and is configured to allow the injecting pen to contact the patient's skin.

An automatic administration instrument includes a syringe and a partition wall in the syringe which partitions the syringe into different rooms for respectively holding plural kinds of drug solutions or a drug and a drug solution. A partition-wall driver displaces the partition wall and an injection needle is connected to the syringe. A body cap attached to the administration instrument body so as to cover the injection needle. The syringe, the partition wall, and the body cap are configured such that displacing the partition wall dissolves or mixes the drug solutions or the drug and the drug solution in a state that the injection needle is covered by the body cap.

A single-use needle cover configured to obscure, protect, or hide at least a portion of a needle from view before, during, and/or after an injection and/or aspiration procedure is disclosed. In some embodiments, the cover includes a housing at least partially containing the needle and configured to couple to a syringe, wherein the housing includes an axis and a guide member. In some embodiments, a sleeve has a plurality of tracks configured to slidingly receive the guide member, wherein the sleeve is configured to retract, extend, and rotate with respect to the housing. In some embodiments, after the sleeve has been retracted and extended one time, a first locking member inhibits further retraction of the sleeve and a second locking member inhibits rotation of the sleeve.

A preferred method to obtain a painless or near painless needle 8 penetration is disclosed to be in the following manner: Applying electric current using a TENS device in conjunction with physically stimulating the injection site at a frequency that is dependent on the frequency of the electric current applied to the injection site, followed by a needle 8 penetration into the skin 2.

The present invention provides an infusion-patch comprising; a cannula; a base; at least one adhesive region in said base suitable for skin attachment; at least one skin-access area within said base; and at least one conduit in fluid connection with said at least one skin access area, wherein said at least one conduit in fluid connection with said at least one skin access area facilitates the transfer of an anesthetic substance within at least a first anesthetic-reservoir which may be removably attached and in fluid connection with said at least one contact area, promoting delivery of said anesthetic substance to said at least one skin-access areas, and wherein said anesthetic substance delivered to said skin-access areas may be at least partially replenished without removing said infusion-patch. Embodiments of the present invention include methods of administering a drug using the infusion-patch.

A painless infusion set has an affixed portion and may have a disposable or reusable insertion device portion. The infusion set or its inserter may have methods or mechanisms to utilize gas, liquid, gel, or solid within phase or through phase change with user-controlled variably slow insertion to reduce pain. In one example, a canister of a pain reducing material is in the insertion device. The pain reducing material can be dispensed onto the skin before, during, or after insertion of the needle or cannula to reduce pain.

Therapeutic agent delivery devices are provided. Aspects of the devices include a syringe that is not surface sterilized, a tip that includes a sterile tissue contacting surface and a needle operably coupled to the syringe and the tip. Also provided are methods of using the devices.

A needle assembly. The needle assembly enabling the analysis of fluid trapped in a flashback chamber after an insertion needle has been inserted into a patient's vein.
