Abstract
The utility model discloses a transfusion needle head capable of reducing the waste of medicine liquor, comprising a tubular needle body. The front end of the tubular needle body is provided with an oblique angle needle point to be inserted into a bottle plug, and the tube wall of the tubular needle body close to the inner surface of the bottle plug is provided with a through-hole for leading the medicine liquor into the transfusion tube. The through-hole is arranged on the tube wall of the tubular needle body close to the rear end, thereby achieving the smooth outflow of the medicine liquor from the through-hole wherein the medicine liquor can not outflow from the oblique angle needle point due to that the liquor level is lower than the oblique angle needle point, and effectively reducing the waste of the medicine liquor.
Description
Technical field
This utility model relates to a kind of medical apparatus, is meant a kind of infusion needle that can reduce liquid waste especially.。
Background technology
Venous transfusion is the important measures of treatment disease, and clinical practice is very extensive.Tube for transfusion is the medical apparatus of venous transfusion indispensability.During transfusion, with the infusion bottle reversal of the natural order of things, infusion needle inserts infusion bottle by the bottle stopper of infusion bottle bottleneck, and medicinal liquid flows into tube for transfusion by infusion needle, and finally enters human vein.
The infusion needle of existing tube for transfusion generally includes a tubulose needle body, and the insertion end of this tubulose needle body is provided with an oblique angle needle point.Mainly there is following shortcoming in this infusion needle: when infusion needle passed the bottle stopper of infusion bottle, the bottle stopper of being worn very easily stopped up the oblique angle needle point, thereby causes unnecessary trouble; Often have certain distance between the medial surface of oblique angle needle point and bottle stopper, and medicinal liquid is to flow into tube for transfusion from the oblique angle needle point, so the medicinal liquid between bottle stopper medial surface and the oblique angle needle point often can not be from the outflow of oblique angle needle point, thereby cause medicinal liquid to waste in large quantities.
Summary of the invention
This utility model provides a kind of infusion needle that can reduce liquid waste, and its purpose is to overcome that oblique angle syringe needle that prior art exists stops up easily and the infusion bottle inner liquid medicine can not complete effusive defective.
The technical solution of the utility model is as follows: a kind of infusion needle that reduces liquid waste, comprise the tubulose needle body, the front end of this tubulose needle body is provided with an oblique angle needle point that is used to insert bottle stopper, and described tubulose needle body offers the through hole that the messenger drug liquid stream is gone into tube for transfusion near on the tube wall of bottle stopper inner surface.
As further improvement of the utility model, described through hole is elongated, in addition, in order to prevent that infusion needle is in inserting the infusion bottle process, since through hole along the end of tubular needle axon to length long, and cause the bottom of the through hole of medicinal liquid by not inserting bottle stopper in the infusion bottle to flow out tube for transfusion, therefore, described through hole along the end of tubular needle axon to length less than the thickness of bottle stopper.
Further improve as of the present utility model, more closely combine with bottle stopper in order to make infusion needle, the tube wall of described tubulose needle body and bottle stopper extruding is provided with protuberance.
As another kind of improvement the of the present utility model, more closely combine with bottle stopper in order to make infusion needle, the tube wall of described tubulose needle body and bottle stopper extruding is to outer lug.
Compared with prior art to description of the present utility model as can be known by above-mentioned, advantage of the present utility model is: by on the tube wall of infusion needle through hole being set, solved the problem that can not circulate owing to the blocked medicinal liquid that causes of oblique angle needle point effectively; In addition, described through hole is opened in the tubulose needle body near on the tube wall of rear end, can't flow out from through hole smoothly from the effusive medicinal liquid of oblique angle needle point thereby can make because liquid level is lower than the oblique angle needle point, thereby reduce the waste of medicinal liquid effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of B among Fig. 1;
Fig. 3 is the cross-sectional view of the A-A direction of Fig. 2.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2, a kind of infusion needle that reduces liquid waste, the tubulose needle body 1 that comprises tube for transfusion 4 front ends, the front end of this tubulose needle body 1 is provided with an oblique angle needle point 2, and described tubulose needle body 1 is gone into the through hole 3 of the strip in tube for transfusion 4 tube walls near offering the messenger drug liquid stream on the tube wall of bottle stopper 5 inner surfacies.When the liquid level of medicinal liquid was lower than oblique angle needle point 2, medicinal liquid just can not flow into tube for transfusion 4 from oblique angle needle point 2, and at this moment, medicinal liquid can also flow in the tube wall of tube for transfusion 4 from through hole 3, thereby had reduced the waste of medicinal liquid effectively.In addition, described through hole 3 also can be circular or other arbitrary shape, and the quantity of through hole 3 can suitably be adjusted according to actual needs.
When through hole 3 along the axial length of tubulose needle body 1 during greater than the thickness of bottle stopper 5, insert in the process of bottle stopper 5 at infusion needle, such situation can appear, the front-end and back-end that are through hole 3 protrude from bottle stopper 5 surfaces externally and internallies respectively, at this moment, medicinal liquid just can flow to the outside of tube for transfusion 4 tube walls from through hole 3, thereby causes waste.In order to prevent that infusion needle is in inserting infusion bottle 6 processes, because through hole 3 is long along the axial length of tubulose needle body 1, and cause the bottom of the through hole 3 of medicinal liquid by not inserting bottle stopper 5 in the infusion bottle 6 to flow out tube for transfusion 4, therefore, described through hole 3 is along the thickness of the axial length of tubulose needle body 1 less than bottle stopper 5.
With reference to Fig. 3, more closely combine with bottle stopper 5 in order to make infusion needle simultaneously, described tubulose needle body 1 is installed with four protuberances 7 with the tube wall lateral surface of bottle stopper 5 extruding.Described protuberance 7 is one group with two, is arranged at respectively on the differing heights of above-mentioned tube wall lateral surface.In addition, the shape of described protuberance 7 is any, and quantity can be regulated according to actual needs.
In addition, the tubulose needle body 1 and the tube wall of bottle stopper 5 extruding are arranged to outside projection, infusion needle is more closely combined with bottle stopper 5.
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
