An indwelling needle is provided which has a simple structure and is capable of securely mounting a needle tip protective tool on the tip portion of an internal needle. The indwelling needle A consists of an external needleincluding a cannulaand a housing, an internal needleincluding a metal needleand a huband a needle tip protective tool. The needle tip protective toolis mounted on the housingwith the metal needleinserted into an inner section so that the metal needlecan be removed together with the internal needlefrom the external needle. A main bodyof the needle tip protective toolhas a cylindrical shape. Window sectionsare provided on opposing circumferential surfaces of the main body. On a rear end marginal section of window section, a movable gripped sectionis provided whose outer sectionextends toward the outside of the main bodyand whose end consists of a grip section. The gripped sectionand the grip sectionare latchable with each other within main body

Internal needle

The present disclosure is directed to an indwelling needle set which includes a needle tip protector device which adds a minimal length to the needle set to maintain operability of the device. To accomplish this, a needle tip protector device is provided for releasable attachment to the needle set. The protector device includes a body and a protecting sleeve which is movable through an opening in the body from an advanced position located substantially within the body to a retracted position extending rearwardly from the body. The protecting sleeve is dimensioned to slidably receive a puncturing needle which includes an increased diameter position which cannot be withdrawn through the protecting sleeve.

Needle tip protector

The present invention provides a medical suturing device structured with a retrieval puncturing needle formed with through-hole; a retrieval member able to be inserted through through-hole; an insertion puncture needle formed with through-hole; a hollow tube that can be inserted through insertion through-hole, and the distal tip of which is formed into a deformable bent portion; and a suture that can be inserted through the inside of hollow tube. The retrieval member is structured with an annular engagement member that can be deformed into a straight shape, a rod member that is connected to annular engagement member, and a grip that is provided with a mark. The mark is furnished on hollow tube, such that when retrieval puncturing needle and insertion puncture needle are in a condition where mark and mark are facing each other, the upper supporter and lower supporter can be detachably attached.

A medical valve device includes a valve unit. The valve unit includes two fluid channels and is positionable to selectably connect two inlet ports and an outlet port such that in one position, fluid introduced at a first inlet port is caused to flow in a first fluid channel to a second inlet port and thence in a second fluid channel from said second inlet port to said outlet port.

Medical valve device

An indwelling needle for reducing the deterioration of the valve by the pressure force of the elastic member. A connector part is provided so as to be moveable within the outer needle body connected to the basal portion of the cannula and provided with the space communicating with the lumen of the cannula therein. Also, within the outer needle body, the valve including the opening and closing aperture through which the tip end side portion of the connector part is liquid tightly penetrated to communicate the lumen of the cannula with the flow path of the connector part as well as the space of the front side portion and the rear side portion of the outer needle body are occluded by closing when the tip end side portion of the connector part is not penetrated therethrough.
