Abstract
An indwelling needle assembly usable in combination with an infusion system for infusion into a patient's body is disclosed.
The indwelling needle assembly is comprised of a needle having a needlepoint insertable into the patient's body; a sleeve slidably fitted on the needle; a catheter including a catheter tube slidably fitted on the sleeve; a base body fixed to a proximal end of the needle; and a slider fixed to the sleeve and slidably engaged with the base body so as to be movable between a first position to have the needlepoint projecting out of the sleeve and a second position to have the needlepoint retracted in the sleeve, wherein the needle, the sleeve, the base body and the slider are unitarily extractable from the catheter.

a needle having a needlepoint insertable into the patient's body;
a sleeve slidably fitted on the needle;
a catheter including a catheter tube slidably fitted on the sleeve;
a base body fixed to a proximal end of the needle; and a slider fixed to the sleeve and slidably engaged with the base body so as to be movable between a first position to have the needlepoint projecting out of the sleeve and a second position to have the needlepoint retracted in the sleeve, wherein the needle, the sleeve, the base body and the slider are unitarily extractable from the catheter.
a needle having a needlepoint insertable into the patient's body;
a sleeve slidably fitted on the needle;
a catheter including a catheter tube slidably fitted on the sleeve;
a base body fixed to a proximal end of the needle; and a slider fixed to the sleeve and slidably engaged with the base body so as to be movable between a first position to have the needlepoint projecting out of the sleeve and a second position to have the needlepoint retracted in the sleeve, wherein the needle, the sleeve, the base body and the slider are unitarily extractable from the catheter.
2. The indwelling needle assembly of claim 1, wherein the sleeve includes an end selected from the group of a taper end and an obliquely cutoff end, the end projecting from the catheter toward the needlepoint.
3. The indwelling needle assembly of claim 1, wherein the catheter includes a distal end portion fitted on the needle, and a taper portion continuously tapering from the catheter tube toward the distal end portion.
4. The indwelling needle assembly of claim 3, wherein the sleeve is so formed as to fill a space held between the needle and the catheter.
5. The indwelling needle assembly of any of claim 1, further comprising:
a latch configured to hold the slider at the first position.
a latch configured to hold the slider at the first position.
6. The indwelling needle assembly of any of claim 1, further comprising:
a stopper latch configured to stop the slider at the second position.
a stopper latch configured to stop the slider at the second position.
7. The indwelling needle assembly of claim 5, further comprising:
an elastic body configured to urge the slider toward the second position; and a release configured to release the slider from the first position, the release being fixed to the base body to allow operation from an exterior of the base body.
an elastic body configured to urge the slider toward the second position; and a release configured to release the slider from the first position, the release being fixed to the base body to allow operation from an exterior of the base body.
8. The indwelling needle assembly of claim 1, wherein the sleeve includes a first sleeve and a second sleeve fitting on the first sleeve.
9. The indwelling needle assembly of claim 1, wherein the needle includes a hollow piercing portion and a translucent body portion, and the sleeve includes a translucent material.
