Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1 to 6, the butterfly needle for an infusion port with good use effect of the present invention comprises a needle base 1, a needle head 2 and a butterfly wing 3, wherein the needle head 2 is fixedly connected to the needle base 1; the butterfly wing 3 comprises a first wing piece 31 and a second wing piece 32 which are connected with each other, and a first connecting seat 33 and a second connecting seat 34 are respectively formed on the lower surfaces of the first wing piece 31 and the second wing piece 32; the needle base 1 is provided with a first limiting groove 11 and a second limiting groove 12 which are detachably connected with the first connecting seat 33 and the second connecting seat 34 respectively.
So, through holding between the fingers first fin 31 and second fin 32 when using, at this moment first connecting seat 33 and second connecting seat 34 outside move with first spacing groove 11 and second spacing groove 12 are connected, and medical personnel can be convenient take up butterfly needle and operate. After the first wing piece 31 and the second wing piece 32 are loosened, the first wing piece 31 and the second wing piece 32 are lifted upwards under the condition that the first wing piece 31 and the second wing piece 32 are in a natural state, and the first connecting seat 33 and the second connecting seat 34 are separated from the first limiting groove 11 and the second limiting groove 12. After the butterfly wing 3 is separated from the needle 2, the needle seat 1 can be more conveniently fixed through the adhesive film, and the phenomenon that the application is incomplete with the edge of the butterfly wing 3 is avoided.
Preferably, as shown in fig. 2, a limiting clamping seat 35 is disposed on each of the sides of the first connecting seat 33 and the second connecting seat 34 that are away from each other, and a clamping groove 13 that can be clamped with the limiting clamping seat 35 is disposed in the first limiting groove 11 and the second limiting groove 12. Preferably, the butterfly wing 3 is formed with two first connecting seats 33 and two second connecting seats 34, and the needle holder 1 is provided with two first limiting grooves 11 and two second limiting grooves 12. In this way, by arranging the limiting clamping seat 35 and the clamping groove 13, the connection effect of the connecting seat and the needle seat 1 is further improved, because the first connecting seat 33 and the second connecting seat 34 are basically in a vertical state when the first wing piece 31 and the second wing piece 32 are in a natural state, the limiting clamping seat 35 is separated from the clamping groove 13, and the butterfly-shaped wing 3 can be conveniently detached from the needle seat 1 and discarded.
Preferably, an operating piece 36 is formed on the upper surface of the joint of the first wing piece 31 and the second wing piece 32. By arranging the operating piece 36, the butterfly wing 3 can be conveniently taken off from the needle seat 1 and discarded, and a new sterile butterfly wing 3 can be conveniently placed on the needle seat 1.
Preferably, the first wing piece 31 and the second wing piece 32 are made of silicone. Medical personnel are through holding between the fingers first fin 31 with second fin 32, deformation takes place for silica gel, makes first connecting seat 33 with second connecting seat 34 joint respectively is in first spacing groove 11 with in the second spacing groove 12.
Preferably, the lower surfaces of the first and second flaps 31 and 32 are provided with anti-slip patterns 37. Therefore, the situation that the butterfly needle slides and falls off the hand is not easy to happen to the medical staff in the process of applying and pulling the needle.
Preferably, as shown in fig. 4, one end of the needle 2 far away from the needle tip is embedded in the needle base 1, and an auxiliary fixing piece 21 is fixedly connected to the outer wall of the needle 2 in the needle base 1. Therefore, the needle head 2 can not rotate and shift in the process of applying the needle by medical staff, and has better stability.
In addition, as shown in fig. 6, the needle head 2 is a non-invasive needle, and the needle tip is bent at a certain angle, so that the cutting edge slope of the needle tip is parallel to the axis of the needle tube, thereby reducing the cutting damage of the cutting edge to the puncture area material in the puncture process, reducing the falling scraps and avoiding the blood vessel blockage caused by the falling scraps.
Preferably, as shown in fig. 3, a top portion 14 is formed in the middle of the upper surface of the needle holder 1, and arc-shaped transition portions 15 are formed on the needle holder 1 on both sides of the top portion 14. Therefore, when the film is pasted, the film can be pasted more tightly.
Compared with the prior art, the utility model discloses a set up and to dismantle the butterfly wing 3 that sets up on needle file 1 for can dismantle the butterfly wing 3 after the completion of syringe needle 2 puncture and abandon, make things convenient for medical personnel's pad pasting, can also be in need take off when syringe needle 2 convenient install new aseptic butterfly wing 3 on the needle file 1, thereby can take off needle file 1.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
