In order to realize these purposes and further advantage according to the present invention, a kind of safe type retention needle is provided, including:
Remaining needle main body be arranged inside puncture needle and is set in the remaining needle casing worn on the outside of the pin of side;
Telescopic sleeve is detachably connected with the remaining needle main body, to control the puncture needle when extracted not with External world's contact, the telescopic sleeve include the stretch rod that multiple diameters are sequentially increased from the inside to the outside, the multiple stretch rod A straight slot is offered on same section respectively;
Lever, is movably set in the side of the telescopic sleeve, and the lever is optionally disposed in through the straight slot Inside or outside the telescopic sleeve;
Wherein, the puncture needle is fixedly linked through the telescopic sleeve with a needle stand, and the needle stand is with being placed in outermost The stretch rod be connected.
Preferably, movable sleeve is connected to an indwelling needle shield in the remaining needle main body.
Preferably, it is provided with the sealing-plug for completely cutting off outside air in the remaining needle main body.
Preferably, the innermost stretch rod of the telescopic sleeve and remaining needle main body clamping or screw thread are placed in Connection.
Preferably, the length under the telescopic sleeve tensional state is more than the length of the puncture needle.
Preferably, the remaining needle main body is connected by a PVC hose with an infusion tee pipe.
Preferably, activity is linked with a fixed link in the PVC hose, and multiple waterproof membranes are wound in the fixed link.
Preferably, precutting is provided between the multiple waterproof membrane, in order to two waterproof UF membranes.
Preferably, the waterproof membrane is in rugosity, and the one side on the waterproof membrane is provided with double faced adhesive tape.
The beneficial effects of the invention are as follows:1) telescopic sleeve, is detachably provided in remaining needle main body, is punctured extracting During pin, telescopic sleeve stretches, and puncture needle is isolated from the outside, avoids and stabs medical worker;2), offered on telescopic sleeve logical Slot, when remaining needle is not used, lever is placed in through straight slot in telescopic sleeve, and telescopic sleeve can not stretch, and avoiding does not make Used time, puncture needle are pulled out;3), equipped with waterproof membrane patient's safe handling during washing one's face and rinsing one's mouth has been convenient for stay on remaining needle Put pin.
Description of the drawings
