Abstract
The utility model relates to a double-hole intravenous transfusion needle of a transfusion device, which comprises a skin tube, a needle base and a double-hole needle tube; wherein, the skin tube and the needle base adopt the skin tube and the needle base of the existing intravenous transfusion needle; the skin tube is jacketed on the needle base; the needle base is connected with the double-hole needle tube; the needle tube is provided with a front hole and a back hole; the front hole is an inclined hole; the back hole is a side hole and concave in the double-hole needle tube; and the front end of the double-hole needle tube is sharp. The intravenous transfusion needle can ensure that when the inclined hole at the front end is blocked, the channel of the transfusion tube can still remain smooth, so that when the needle puncturing direction is not parallel to the intravenous path, the transfusion speed can not be influenced. The utility model can be widely used in the field of the intravenous transfusion.
Description
Technical field this utility model relates to the venoclysis needle of using on a kind of transfusion device, is a kind of venoclysis needle of diplopore specifically.
Venoclysis needle on the present transfusion device of background technology is made up of leather hose, needle stand, single hole needle tubing, one inclined hole is arranged before the single hole needle tubing, during use, needle point thrusts vein, and inclined hole enters the vein inner chamber, the transfusion device inner liquid medicine flows into human vein by inclined hole, when needle tubing puncture direction and human vein moved towards not parallel, the inclined hole of unidirectional needle tubing just might get clogged or partial blockage, at this moment, transfusion device inner liquid medicine inflow vein also will be obstructed or the medicinal liquid flowing velocity slows down, and this has influenced patient infusion.
The summary of the invention the purpose of this utility model is exactly that a kind of needle tubing medicinal liquid flow velocity venoclysis needle of impregnable diplopore still when inclined hole is hindered is provided in order to solve the shortcoming that above-mentioned venoclysis needle exists.
For reaching these purposes, this utility model adopts following technical scheme:
This utility model is by leather hose, needle stand, the diplopore needle tubing is formed, leather hose, needle stand adopts the leather hose on the present venoclysis needle, needle stand, leather hose is connected on the needle stand, needle stand is connected with the diplopore needle tubing, two holes are arranged: preceding hole and metapore on the diplopore needle tubing, preceding Kong Weiyi inclined hole, inclined hole before the roughly the same present single hole needle tubing, metapore in the past hole root begins backward, is come out by the opposite side of needle tubing, and metapore is a side opening, metapore is by needle tubing tube wall indent, metapore is positioned at the opposite side rear portion in preceding hole, diplopore needle tubing front end point, and the diplopore needle tubing thrusts human vein, when needle tubing direction and vein move towards not parallel, when appearance needle tubing front end inclined hole was blocked by wall of vein, the side opening nature of opposite side added the indent of upper-side hole self away from wall of vein, the transfusion device inner liquid medicine just flow to intravenous from side opening effectively, the transfusion device inner liquid medicine flows and can not be obstructed, and can not slow down, and the medicinal liquid flow velocity is influence not.
Compare with present venoclysis needle, it replaces original single hole needle tubing with the diplopore needle tubing, makes that medicinal liquid can come out from side opening when the preceding inclined hole of needle tubing was hindered, and the transfusion device inner liquid medicine flows and can not stop, and can not slow down, and flow velocity is unaffected.
Description of drawings Fig. 1 product structure figure
Among the figure: 1, leather hose 2, needle stand 3, diplopore needle tubing 4, preceding hole 5, metapore
Specific embodiment this utility model is made up of leather hose 1, needle stand 2, diplopore needle tubing 3, leather hose and needle stand that leather hose 1, needle stand 2 adopt on the present venoclysis needle, and leather hose 1 is connected on the needle stand 2, and needle stand 2 is connected with diplopore needle tubing 3, and diplopore needle tubing 3 has 2 holes; Preceding hole 4 and metapore 5, preceding hole 4 is an inclined hole, the inclined hole on the roughly the same present venoclysis needle in preceding hole 4, metapore 5 hole 4 roots in the past begins backward, come out by diplopore needle tubing 3 sides, metapore 5 is a side opening, and metapore 5 is formed by diplopore needle tubing 3 tube wall indents, metapore 5 is positioned at the opposite side rear portion in preceding hole 4, the front end point of diplopore needle tubing 3, diplopore needle tubing 3 thrusts vein during use, and preceding hole 4 and metapore 5 all enter intravenous, fix needle stand 2, can carry out venous transfusion.
