The medical apparatus further includes an integrated detecting device provided as a unit including the electrocardiogram-measuring device and the blood-leakage-detecting device.

Medical apparatus

A clamping device comprising: a one end portion having a locked part at a tip and an other end portion having a locking part capable of locking the locked part, wherein the one end portion or the other end portion has an interfering part, and when the one end portion is further pressed with the locked part being locked by the locking part, the interfering part interferes with an appropriate part and prevents further movement of the locked part.

Clamping device with stop points to prevent excess closure of clamp

A clamping device is provided in which an other end portion is prevented from being excessively displaced in the transition from a clamped state to an unclamped state. A clamping device includes a one end portion having a locked part at a tip, an other end portion having a locking part capable of locking the locked part, a middle portion continuous with the one end portion and with the other end portion, and an insertion hole (H, H) allowing a flexible tube T to be inserted therethrough. An unclamped state is established when the locked part locked is unlocked by bending the other end portion such that the other end portion is displaced from the one end portion. The clamping device is configured to clamp the flexible tube T in a clamped state where a first projection and a second projection are positioned close to each other and to intercept a flow of a fluid at a clamped position. The clamping device further includes displacement-restricting members capable of restricting the displacement of the other end portion in a transition from the clamped state to the unclamped state.

Clamping device

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

A fistula catheter in which an intracorporeal fixing part comprises an inner balloon and an outer balloon is disclosed, whereby it is possible to prevent removal from the fistula by means of the inner balloon, even if the outer balloon deflates.

Fistula catheter

A puncturing needle assisting tool. A first rotating portionrotates from an open to a closed position, around a first hinge connecting portionas the rotating center, to the surface side of an assisting tool main unitto close the surface opening of a first guide groove. A second rotating portionrotates from an open position to a closed position, around a second hinge connecting portionas the rotating center, to the surface side of an assisting tool main unitto close the surface openings of second guide groovesthrough. The puncturing needles move along the guide grooves to puncture into the body in a proper state, without shifting. Locking protrusionsmaintain the closed positions of the first and second rotating portionsrespectively.

Puncturing needle assisting tool

A fistula catheter which allows a supply tube to be easily connected to a body-external fixing member positioned on the body surface side, and which is only slightly invasive for a patient is provided. The fistula catheterincludes a tube bodywhich is inserted into a fistula formed in the abdominal wall and the wall of the alimentary canal; a body-external fixing partwhich is linked to one end of the tube bodyand positioned on the abdominal wall surface side of the fistula; and a body-internal fixing partwhich is linked to the other end of the tube bodyand positioned inside the wall of the alimentary canal. The body-internal fixing part, and the fistula catheter has a flow path allowing fluid to flow through the body-external and body-internal fixing members. The body-external fixing partincludes a flexible tubeand is connected substantially at right-angles to the axial direction of the tube body

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.
