Disclosure of Invention
The utility model provides an infusion needle head protection device for solving the problems that the needle cap and the needle head of the existing disposable infusion needle are separated, and the injury and the like are easily caused to patients or nursing staff after the disposable infusion needle is used.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides an infusion syringe needle protection device, includes the needle handle, its characterized in that, the needle handle top is equipped with the syringe needle, the both sides of needle handle are equipped with the needle wing, be equipped with the protective sheath on the syringe needle, the bottom of protective sheath articulates at one side needle wing, realizes that the protective sheath is rotatory, the protective sheath is equipped with the needle groove, be equipped with the arch on the needle handle, the correspondence is equipped with spacing hole on the protective sheath, and the rotatory spacing hole card of protective sheath realizes spacing fixedly at protruding top.
Furthermore, a rotating shaft support is arranged at the bottom of the protective sleeve and is movably connected with the needle wing through a pin shaft.
Furthermore, the protective sheath is cylindric or square form, is equipped with the top, and the side opening is the needle groove.
Furthermore, an infusion tube is connected below the needle handle.
Furthermore, one side of the protective sleeve is a needle groove, or two sides of the protective sleeve are communicated.
Further, the protective sleeve is made of hard plastic materials.
Further, the diameter of the protective sleeve is slightly larger than that of the needle handle.
Furthermore, the protective sleeve is provided with a movable handle, so that the protective sleeve can be conveniently held and rotated.
The utility model discloses following beneficial effect has:
the utility model discloses articulate the protective sheath on the needle wing, change needle cap and syringe needle isolating construction, effectively solve the problem that the needle cap is lost, secondly, on the transfer line of rotatory needle handle rear end of protective sheath from the syringe needle through articulated structure, do not hinder infusion work, prevent to lose, on will protecting sleeve gyration to the syringe needle again after the use, when retrieving the transfusion system, prevent that the syringe needle from exposing in the outside, effectively solve the syringe needle and cause the injury to patient or nursing staff.
The utility model discloses a movable handle removes the protective sheath for the better syringe needle of keeping away from of hand prevents to stab, plays fixed spacing through the cooperation of protruding and spacing hole between needle handle and the protective sheath, prevents that protective sheath swivelling movement angle is too big, prevents that the protective sheath from breaking away from.

1. The needle comprises a needle wing, 2, a needle handle, 3, a needle head, 4, a protective sleeve, 5, a pin shaft, 6, a rotating shaft support, 7, a needle groove, 8, a transfusion tube, 9, a limiting hole, 10, a bulge, 11 and a movable handle.
Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1-6, an infusion syringe needle protection device, includes needle handle 2, its characterized in that, 2 tops of needle handle are equipped with syringe needle 3, one side of needle handle 2 is equipped with needle wing 1, be equipped with protective sheath 4 on the syringe needle 3, the bottom of protective sheath 4 articulates at needle wing 1, realizes that protective sheath 4 is rotatory, protective sheath 4 is equipped with needle groove 7, be equipped with arch 10 on the needle handle 2, the last correspondence of protective sheath 4 is equipped with spacing hole 9, and the rotatory spacing hole 9 card of protective sheath 4 realizes spacing fixedly at arch 10 tops.
The bottom of the protective sleeve 4 is provided with a rotating shaft support 6, and the rotating shaft support 6 is movably connected with the needle wing 1 through a pin shaft 5.
The protective sheath 4 is cylindric or square form, is equipped with the top, and the side opening is the needle groove 7.
The lower part of the needle handle 2 is connected with an infusion tube 8.
One side of the protective sleeve 4 is a needle groove 7, or two sides of the protective sleeve 4 are communicated.
The protective sleeve 4 is made of hard plastic materials.
The diameter of the protective sheath 4 is slightly larger than the diameter of the needle shaft 2.
The protective sheath 4 is provided with a movable handle 11, so that the handheld rotation is facilitated.
Example (b):
fig. 1 is a transfusion needle head protection device, is equipped with protective sheath 4 on the syringe needle 3, and protective sheath 4 articulates on needle wing 1, and one side of protective sheath is equipped with needle groove 7 for hold the syringe needle, during the use, as shown in fig. 4, handheld activity handle 11 is rotatory protective sheath 4 left, and protective sheath 4 drops from the syringe needle, and fig. 5 is that the protective sheath rotates 8 departments of rear end transfer lines to the needle handle, and at this moment, medical personnel just can use this transfusion system, and the device can not influence the infusion, and is safe convenient.
