Abstract
The utility model discloses a stainless steel tube needle with four inclined planes, comprising a needle tube, a main inclined plane arranged on the front portion of the needle tube, a right inclined plane and a left inclined plane arranged by the sides of the main inclined plane, a cutting edge line form at the joint point of the left inclined plane and the right inclined plane and a bottom inclined plane arranged on the bottom of the needle tube under the right inclined plane and the left inclined plane. The bottom inclined plane intersects with the cutting edge line. The utility model reduces the height of the cutting-edge line, without changing the thickness of the needle tube wall and affecting the strength of the needle tube, thereby improving the keenness of the needle tip, and reduces the feel of pain of the patient.
Description
Technical field
This utility model relates to a kind of rustless steel bobbin.
Background technology
The needle tubing of stainless steel extensively applies in the medical device product such as subcutaneous injection, venous transfusion, defeated blood sampling, in order to alleviate the pain of user, it is sharp to reduce puncture force to require needle point to try one's best, the needle point structure of existing needle tubing mostly is three inclined-plane geometries, it is main inclined plane 11 of needle point heel, the a pair of skew back face 12,13 in needle point end, the skew back face grind be main inclined plane grind finish after, along what carry out after the needle tubing axis turns over certain angle.
Generally believing that needle point thrusts patient body and makes it produce pain, mainly is owing to needle point in the needle point piercing process causes involving of skin or tissue.To same individual, the power of pain depends on the size of the degree of involving, and it is then relevant by the height of the formed puncture cutting edge of pinpoint inclined plane line to involve degree, and cutting edge line height is big more, and it is strong more to keenly feel.In order to reduce the height of puncture cutting edge line, the direct way of tool is to reduce the needle tubing wall thickness, and the needle tubing wall thickness reduces the rigidity that then can weaken needle tubing.
Summary of the invention
The purpose of this utility model is: a kind of four beveled point rustless steel bobbins are provided, this bobbin is provided with inclined-plane, the end in bottom, inclined-plane, both sides, inclined-plane, the end and cutting edge line intersect, do not changing the needle tubing wall thickness, do not influencing under the prerequisite of needle tubing rigidity, dwindled the height of cutting edge line, thereby improved the sharpness of needle point, reduced patient's pain.
The technical solution of the utility model is: a kind of four beveled point rustless steel bobbins, comprise needle tubing, the forward main inclined plane of needle tubing, the right tilted surface of main inclined plane both sides and left tilted surface, right tilted surface and left tilted surface intersect the cutting edge line that forms, the needle tubing bottom of described right tilted surface and left tilted surface below is provided with inclined-plane, the end, and the front end on inclined-plane, the end and cutting edge line intersect.
The further technical scheme of this utility model is: a kind of four beveled point rustless steel bobbins, comprise needle tubing, the forward main inclined plane of needle tubing, the right tilted surface of main inclined plane both sides and left tilted surface, right tilted surface and left tilted surface intersect the cutting edge line that forms, the needle tubing bottom of described right tilted surface and left tilted surface below is provided with inclined-plane, the end, and the front end on inclined-plane, the end and cutting edge line intersect; Inclined-plane, the described end is and is symmetrical set.
The utility model has the advantages that:
Because this utility model is provided with inclined-plane, the end in bottom, inclined-plane, needle tubing both sides, inclined-plane, the end and cutting edge line intersect, and therefore do not changing the needle tubing wall thickness, are not influencing under the prerequisite of needle tubing rigidity, have dwindled the height of cutting edge line, thereby improved the sharpness of needle point, reduced patient's pain.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is a vertical view of the present utility model;
Fig. 4 is a upward view of the present utility model;
Fig. 5 is an axonometric chart of the present utility model.
Wherein: 1 needle tubing; 11 main inclined planes; 12 right tilted surfaces; 13 left tilted surfaces; Inclined-plane, 14 end; 21 needle points; Tip position during inclined-plane, the 22 no end; 31 tube chambers; 32 tube walls; 41 cutting edge lines.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of four beveled point rustless steel bobbins, comprise needle tubing (1), the forward main inclined plane of needle tubing (1) (11), the right tilted surface (12) of main inclined plane (11) both sides and left tilted surface (13), right tilted surface (12) and left tilted surface (13) intersect the cutting edge line (41) that forms, needle tubing (1) bottom of described right tilted surface (12) and left tilted surface (13) below is provided with inclined-plane, the end (14), inclined-plane, the end (14) is and is symmetrical set, and the front end of inclined-plane, the end (14) and cutting edge line (41) intersect.
Because this utility model is provided with inclined-plane, the end (14) in bottom, needle tubing (1) inclined-plane, both sides, inclined-plane, the end (14) intersects with cutting edge line (41), therefore do not changing the needle tubing wall thickness, do not influencing under the prerequisite of needle tubing rigidity, dwindled the height of cutting edge line (41), thereby improved the sharpness of needle point, reduced patient's pain.
Claims (2)
1. beveled point rustless steel bobbin, comprise needle tubing (1), the forward main inclined plane of needle tubing (1) (11), the right tilted surface (12) of main inclined plane (11) both sides and left tilted surface (13), right tilted surface (12) and left tilted surface (13) intersect the cutting edge line (41) that forms, it is characterized in that: needle tubing (1) bottom of described right tilted surface (12) and left tilted surface (13) below is provided with inclined-plane, the end (14), and the front end of inclined-plane, the end (14) and cutting edge line (41) intersect.
2. four beveled point rustless steel bobbins according to claim 1 is characterized in that: inclined-plane, the described end (14) is and is symmetrical set.
