Abstract
The utility model relates to a liquid cleaning bottle cork acupuncture needle of a transfusion set, which consists of a needle head (1), a needle rod (2), a buffering stage (3), a base (4) and a conduit (5), wherein the needle head (1), the needle rod (2), the buffering stage (3) and the base (4) are communicated with the conduit (5). The needle head (1) is provided with holes (6), and the lower part of the needle rod (2) is provided with a grooved hole (7). The lower edge of the grooved hole is about 2 to 3 mm away from the buffering stage. The liquid cleaning bottle cork acupuncture needle can completely drop liquid medicine inside a transfusion bottle so as to reach the dosage, to realize the medicine effect and to avoid the medicine waste during the healing of the patient. The liquid cleaning bottle cork acupuncture needle of the transfusion set can be widely used for the transfusion set and the disposable transfusion set.
Description
One, technical field:
This utility model relates to the bottle stopper puncture needle on a kind of medical Transfusion device.
Two, background technology:
Existing transfusion device bottle stopper puncture needle has all been opened the bottom aperture of the aperture, particularly shank of transfusion and can have been carried some residual medicinal liquids, but not necessarily flow to end residual medicinal liquid on syringe needle, shank.This be since in clinical the nurse with syringe needle puncture bottle stopper after, be difficult to guarantee that shank bottom aperture can accurately arrive the upper surface place of bottle stopper in the bottle, thereby can cause aperture following medicinal liquid in shank bottom can't fail clean result.
Three, summary of the invention:
At above-mentioned deficiency, the purpose of this utility model is a kind of transfusion device bottle stopper puncture needle that can flow to end the medicine bottle inner liquid medicine clinically of design.
The technical essential of finishing the clean liquid bottle stopper of transfusion device puncture needle is: be provided with one or plural groove hole is set symmetrically in the bottom of shank.The width in groove hole is the aperture of the pin hole of puncture needle approximately; Groove hole length is about 5mm～10mm.The lower edge in groove hole is about 2mm～3mm from the buffering step.This design size is so that make the lower edge in groove hole reach the upper surface place of bottle interior bottle stopper, even the lower edge in groove hole is fallen into in the bottle stopper.
Four, description of drawings:
Fig. 1, Fig. 2 are that the master of the clean liquid bottle stopper of transfusion device puncture needle looks sketch map.
Five, the specific embodiment:
Introduce the embodiment of the clean liquid bottle stopper of transfusion device puncture needle in detail below in conjunction with accompanying drawing.
Fig. 1 is that the embodiment master of the clean liquid bottle stopper of the transfusion device puncture needle made with metal tube and plastic tube looks sketch map.
The upper end of metal tube syringe needle (1) is the transfusion hole, promptly claims pin hole (6), and the bottom plastic packaging of metallic rod (2) becomes buffering step (3) and makes base (4), and is connected with plastic infusion conduit (5).
Get through one or get through two and plural groove hole (7) symmetrically in the bottom of shank (2).About 5mm～the 10mm of groove hole (7) length, width is the pinhole aperture of puncture needle approximately, generally should be less than or equal to pinhole aperture.
There are four limits, upper and lower, left and right in groove hole (7), and the lower edge in groove hole is from the about 2mm～3mm of buffering step.With groove hole (7) and shank (2) and vertical the getting through of conduit (5).Because rubber bottle cover has bigger elasticity, behind the rubber closure that punctures clinically,, the lower edge in groove hole can be moved downward because rubber closure recovers elastic deformation.After syringe needle (1) passes bottle stopper (generally about 1.5mm～3.5mm is thick for bottle stopper), can make the lower edge in groove hole (7) reach the upper surface place of bottle interior bottle stopper, even the lower edge in groove hole (7) is absorbed in the rubber bottle cover.This has just guaranteed medicinal liquid, and all stream is clean.
Fig. 2 looks sketch map with the embodiment master that plastic pipe and plastic material are made the clean liquid bottle stopper of the incorporate transfusion device of plastics puncture needle.
Get through one or more transfusion holes on the syringe needle (1), i.e. pin hole (6).Buffering step (3) and base (4) are made in the bottom of shank (2), and are connected with transfusion catheter (5).
Get through one or more grooves hole (7) in the bottom of shank (2).About 5mm～the 10mm of length in groove hole (7), width should be less than or equal to pinhole aperture.With groove hole (7) and shank (2) and vertical the getting through of conduit (5).The lower edge in groove hole (7) is from the about 2mm～3mm of buffering step (3).Because rubber bottle cover has bigger elasticity, after syringe needle (1) passed rubber bottle cover, rubber bottle cover recovered elastically-deformable result, and the lower edge in groove hole can be moved downward, and reached the upper surface place of bottle interior bottle stopper, perhaps was absorbed in the rubber bottle cover.This will make the medicinal liquid stream in the bottle clean.
Claims (3)
1. the clean liquid bottle stopper of transfusion device puncture needle, form by syringe needle (1), pin hole (6), shank (2), groove hole (7), buffering step (3), base (4), transfusion catheter (5), it is characterized in that being provided with groove hole (7) in shank (2) bottom of general infusion set bottle stopper puncture needle.
2. the clean liquid bottle stopper of transfusion device as claimed in claim 1 puncture needle is characterized in that: the about 5mm～10mm of length of groove hole (7), width should be less than or equal to the aperture of pin hole.
3. the clean liquid bottle stopper of transfusion device as claimed in claim 1 or 2 puncture needle, the lower edge that it is characterized in that at least one groove hole (7) is from the about 2mm～3mm of buffering step.
