Proposed as a needle. Furthermore, when transfusing or transfusing into a blood vessel, first, puncture the puncture needle with the inner and outer needles integrated into the blood vessel, then pull out only the inner needle and connect a connector such as a blood transfusion set (or infusion set) to the outer needle. It is also proposed that the outer needle hub is provided with a wing-like material for connecting to the hub and then fixing it to the skin surface with tape or the like.

As the outer needle 10, a plastic needle made of a fluororesin such as Teflon or an olefin resin such as polypropylene or polyethylene is usually used. Such an outer needle hub 10
The outer needle hub 20 fixed to the base 11 has a pair of wings 95 extending from the substantially central portion 31 of the outer needle hub 20 to the left and right sides in the axial direction of the outer needle 10. The blade 95 is separated from the outer needle hub 20 by a notch 91 having a substantially triangular shape on the tip side from the central portion of the outer needle hub 20. Further, the wing 95 integrally extends with the outer needle hub from the bottom surface of the central portion 31 of the outer needle hub 20 as shown in FIG.
It has a predetermined angle with the axial direction of the hub. This angle is an angle when the outer needle 10 is fixed to the skin surface in a state of being left in the blood vessel, and normally, this angle θ is preferably 5 to 10 degrees. Further, the blade 95 is located substantially on the same line as the outer needle hub 20 on the axial leading end side. Also, wings 95
The central portion 31 of the outer needle hub 20 from which the
And the outer needle hub 20 is located closer to the base end side than the fixed portion. The wing 95 and the outer needle hub 20 are integrally formed by one member. Although these materials are polypropylene, soft PVC or the like may be used instead.

実に防止できる。A valve body 70 as shown in FIGS. 2 to 4 is mounted inside the outer needle hub 20 fixed to the base portion 11 of the outer needle 10. The valve body 70 has a disc-shaped portion 71 having a valve mechanism, and a ring-shaped rib portion 75 protruding from the peripheral edge of a flat surface 71a of the disc-shaped portion. The disk-shaped portion 71 has a disk shape, and has a diameter of about 5 to 10 mm and a thickness of about 1 to 1.5 mm. The means for providing the disc-shaped portion 71 with the valve mechanism is not particularly limited, but it is usually preferable to make a linear cut. More specifically, as shown in FIG. 3, for example, a disk-shaped portion 71 made of an elastic material such as silicone rubber is linearly cut from both upper and lower surfaces, and a first cut portion 72 intersects with each other at the central portion. The thing which provided the 2nd notch 73 is mentioned. Thus, it is possible to reliably prevent blood from leaking from the outer needle hub 20 during an operation of pulling out the inner needle and connecting a connector or the like as a rod-shaped body during the procedure.

The ratio (L / D) of the length L of the rib portion to the outer diameter D of the rib portion 75 is 0.15 or more, particularly 0.16 to 0.2.
It is said that If this value is less than 0.15, it is difficult to securely fix the valve body in the outer needle hub 20, and the valve body may fall off.

A ring-shaped groove 42 is provided for the purpose. The groove portion 42 is provided so as to be recessed in the axial direction, the rib portion 75 is inserted into the groove portion 42, and the outer peripheral surface and the inner peripheral surface of the rib portion 75 are sandwiched by the outer peripheral surface and the inner peripheral surface of the groove portion 42, respectively. To be done. As a result, the valve body 70 is securely fixed.

Preferably, there is an end 35 (Fig. 2) that abuts b (Fig. 4). Then, if the valve body 70 is clamped and fixed by the first outer needle hub portion 40 (in particular, the end portion 35) and the second outer needle hub portion 30 (in particular, the groove portion 42), the valve body can be significantly fixed. Certainty improves. When sandwiching the valve body 70, it is preferable to sandwich the valve body 70 in a state of being appropriately compressed by the two members 30 and 40. A suitable compression rate is 50% or less,
Especially, it is set to 20 to 30%. If this value is less than 50%, the valve body 70 may drop off. The compression ratio is (the axial length of the valve body after compression / the axial length of the valve body before compression) x
It is defined as 100. In addition, the first outer needle hub body 40
A taper surface 41, more preferably a luer taper surface, into which a rod-shaped body such as a connector described later is fitted is provided at the rear part of the inner cavity portion (Fig. 2).

First, before use, the inner needle 50 is inserted into the outer needle 10 via the outer needle hub 20 as shown in FIG. That is, when the inner needle hub 60 is completely inserted into the base end portion of the outer needle hub 20, the blade tip portion 50a of the inner needle 50 is in a state of protruding from the tip of the outer needle 10,
Enables smooth puncture of blood vessels. At this time, the inner needle 5
The relationship between 0 and the valve body 70 is closely contacted as shown in FIG. In this state, for example, while grasping the inner needle hub 60, puncture the blood vessel, introduce the outer needle 10 into the blood vessel, and after confirming that the blood vessel has been secured, the inner needle 50 is removed from the outer needle hub 20. (Fig. 6). At this time, the valve body 70 is naturally closed and leakage of the blood vessel from the outer needle hub 20 is prevented. Then, as shown in FIG. 7, the connector 100 as a rod-shaped body of a blood transfusion or infusion set (not shown) is fitted into the outer needle hub 20, and the tip of the connector 100 is inserted so as to penetrate the valve body 70. The wing 95 in the open state is fixed to the skin surface with the tape 120. At this time, since the outer needle 10 and the outer needle hub 20 are likely to move in the directions of arrows (a) and (b) around the center portion 30 as shown in FIG. 7, the bending of the tube due to body movement is buffered. , Do not apply force to the outer needle puncture part.
