Abstract: The present invention relates to a safety catheter assembly. One aspect of the present invention provides a safety catheter assembly which comprises: a catheter having a tube; and a needle assembly, wherein the needle assembly comprises: a housing which is detachably coupled to the catheter; a handle member which is provided to be movable forward and backward within the housing; a needle which is mounted on the handle member; a fixing member for fixing the handle member to the housing in a forwardly moved position of the handle member when the handle member is forwardly moved such that the needle is exposed to the outside by passing through the catheter; and an elastic member for backwardly moving the handle member such that the needle is inserted into the housing when the handle member is released from the fixed state.

Abstract: The present invention relates to a syringe-coupled safety assembly and a safety syringe including the same. According to one aspect of the present invention, provided is the syringe-coupled safety assembly comprising: a cover having a space part for allowing a syringe to enter therein, and a first through-hole through which a syringe needle passes; and a fixing unit having a second through-hole into which a syringe hub, in which the needle is mounted, is inserted, disposed inside the cover so as to be capable of proceeding in the direction becoming closer to the first through-hole and of retracting in the direction becoming farther from the first through-hole, fixed to the cover in a proceeded state, and provided so as to allow the syringe inserted into the second through-hole to retract when the fixed state thereof of the cover is released from the proceeded state.

Abstract: An oil seal apparatus and a blower including the same are disclosed. The oil seal apparatus and the blower can assemble a body pipe quickly regardless of assembling direction of the body pipe when assembling the body pipe by forming a plurality of oil return holes, i.e., forming more than four or five oil return holes at upper portion, lower portion, left portion, and right portion of an outboard surface of the body pipe. The oil seal apparatus may be mounted in a shaft through-hole formed at an oil box of a blower.

Abstract: Disclosed is a case structure for housing a fishing hook capable of holding a fishing hook in safe and being attached to a fishing rod case without movement. The case structure for housing the fishing hook includes: a case body having a fishing hook receiving part with a predetermined area for receiving and holding a fishing hook and a cover part coupled to the fishing hook receiving part to be opened and closed; and a projection formed on the fishing hook receiving part in such a manner as to be projected by a predetermined height from the top surface of the fishing hook receiving part for catching the fishing hook. The case body has an elastic fishing string mounted at one side of the case body and having a fixing ring, so that the fishing hook case can be attached to the fishing rod case without movement.
