the method is characterized in that: the front end of the needle sleeve is in an open conical shape; the needle sleeve handle and the needle sleeve are of an integrated structure, and the middle part of the needle sleeve is provided with a buckle; the blade is in a semicircular and trapezoidal design, and a blade protective sleeve is arranged on the cutting edge of the blade; the blade buckle is designed into a semicircular ring and a trapezoid; the pull wire is fixed on the outer surface of the needle sleeve by the pull wire fixing buckle and is connected with the blade protective sleeve.
Preferably, a blade is arranged in the blade buckle, extending edges are arranged on two sides of the blade buckle and can guide the blade to enter the blade buckle, and the blade buckle and the extending edges of the blade buckle and the inner blade form a W shape.
Preferably, the lower part of the needle sleeve is designed in parallel, and the blade buckle are vertically fixed inside the needle sleeve through the blade fixing pile.
Preferably, the blade protection sleeve is pulled out from the tail end of the needle sleeve by the pull wire.
Preferably, the needle sleeve is provided with a clamping groove, and the needle stem handle can be pulled back and forth in the clamping groove.
(III) advantageous effects
The utility model provides a venous transfusion needle cover possesses following beneficial effect:
the product optimizes the defects that the existing intravenous infusion needle is easy to cause needle stick injury, is easy to cause physical injury of medical care personnel, causes environmental pollution and the like; the needle stick injury is avoided, the environmental pollution is reduced, and the allergy or other injuries caused by the contact of medical care personnel with the infusion drug are avoided. Simple and easy operation, economy and convenience. Is a humanized, safe, green and environment-friendly design product.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a partial enlarged view of the lower half of the design of the present invention;
fig. 3 is a schematic view of the local structure of the present invention.
In the figure: 1-needle head, 2-needle stem handle, 3-needle stem, 4-needle sleeve handle, 5-transfusion thin tube, 6-blade, 7-blade fixing pile, 8-needle sleeve clamping groove, 9-needle sleeve, 10-blade protecting sleeve, 11-stay wire, 12-stay wire fixing buckle and 13-blade buckle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, the present invention provides a technical solution:
the technical scheme is as follows: when in operation, the left hand holds the needle sleeve handle 4, and the right hand holds the needle stem handle 2 to push the needle 1 out from one side of the needle sleeve 9 along the needle sleeve clamping groove 8 for transfusion. When the transfusion is finished, the left hand presses the needle sleeve handle 4, and the right hand holds the needle stalk handle 2 to return the needle 1 from one side of the needle sleeve 9 to the needle sleeve 9 along the needle sleeve clamping groove 8. After the contaminated syringe needle 1 got into needle cover 9, untie in the fixed knot 12 of acting as go-between with the acting as go-between 11, then slowly pull out the acting as go-between 11 for the blade protective sheath breaks away from blade 6 completely, then with the position of pinching two blade spud piles 7 of needle cover 9 tail ends, with the slow extrusion gently of hand alright cut off the infusion tubule 5 of connecting needle stalk handle 2, will pollute syringe needle 1 again and abandon in sharp container box, accomplish the use of this utility model design promptly.
In conclusion, the venous transfusion needle sleeve is improved on the basis of the existing disposable venous transfusion (blood sampling) needle, and is low in cost and convenient to use. When the needle is used, the needle sleeve is not separated from the needle, so that the problem that the needle sleeve is left everywhere is avoided, and the environment is maintained neatly. The needle leaves the patient body and directly enters the needle sleeve during operation, thereby avoiding the contact of the polluted needle head with the outside, protecting the nursing staff from puncture injury, and reducing the harm of the liquid medicine flowing out to the body of the medical staff and the pollution to the environment.
It is noted that in the present disclosure, unless otherwise explicitly specified or limited, a first feature "on" or "under" a second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
