Abstract
The invention discloses a puncture needle for bottle corks, which prevents the puncture needle from being easily polluted by air and has the advantages of more reliable and effective operation of puncturing. The invention comprises a puncture needle and an exhaust pipe, wherein, a pipe clamp is arranged in the middle of the exhaust pipe, and the outer surface of the puncture needle is frosted. As the pipe clamp is arranged on the exhaust pipe, aerating or chocking measures can be conveniently adopted, namely that the pipe clamp can conveniently switch on and off the exhaust pipe as well as perform the function of preventing air pollution. The outer surface of the puncture needle is frosted, which increases friction force, and the puncture needle is not easy to pull out after being inserted into a bottle cork; thus, puncturing reliability is improved, and secondary pollution to liquid is reduced.
Description
Technical field
The present invention relates to a kind of puncture needle of medical infusion bottle bottle stopper.
Background technology
The present normal transfusion device that uses is nothing more than two kinds, and a kind of is the transfusion device that collection is ventilated and logical liquid function is an one, and another kind is ventilation and the isolating transfusion device of logical liquid function.When these two kinds of transfusion devices are applied to exist when non-PVC co-extrusion film packing liquid is infused many problems.When above-mentioned first kind of transfusion device and non-co-extrusion PVC film packing liquid are used, because its construction features inevitably will enter air, therefore can cause air pollution, the design original intention that this has just run counter to non-co-extrusion PVC film packing liquid promptly prevents air pollution.Therefore, when transfusion device that to adopt collection ventilation and logical liquid function be one and non-co-extrusion PVC film packing liquid were used, non-co-extrusion PVC film packing liquid had just lost meaning.In addition, 1. when being used with non-co-extrusion PVC film packing liquid, when non-PVC co-extrusion film packing liquid is about to be totally lost, the bag internal pressure appears in meeting and external atmosphere pressure is poised state, this moment, non-PVC co-extrusion film packing liquid stopped to instil in dropper, but solution also can descend automatically in the dropper, owing to have the part air in the dropper, after solution dripped off in the dropper, the air in the dropper will enter in the tube for transfusion from its underpart.When dropper internal pressure during less than atmospheric pressure, solution can instil in dropper once more, in this case, because the continuous drip once more of surplus solution in the bag can be pushed the air in the tube for transfusion of dropper bottom to blood vessel, cause the danger of air input blood vessel easily.2. when making up a prescription, if subsidiary in non-PVC co-extrusion film packing the injection air too much, it is too much perhaps to allocate medicinal liquid into, when causing bag internal pressure greater than external atmosphere pressure, will occur the phenomenon of the outside discharge of breather in the infusion process, promptly rushes down leakage.3. this transfusion device bottle stopper puncture needle is a plastic production, the head smoothness is higher, but not the rubber closure of co-extrusion PVC film package bag is less, and elasticity is bigger, be not easy to insert the syringe needle bottom when therefore puncture occurs puncturing for the first time often, easily bounce-back outward needs to insert once more, often causes easily polluting.This mainly is the exterior light slippery height of puncture needle, so frictional force is less, is difficult for being gripped by bottle stopper.When above-mentioned second kind of ventilation and the isolating transfusion device of logical liquid function and non-co-extrusion PVC film packing liquid are used, the subject matter that exists is, if be used for continuous transfusion, and when the liquid of non-PVC co-extrusion film packing and bottling liquid are used alternatingly, the breather process of preserving occurs and easily pollute, even be dropped.If be dropped, after changing bottling liquid, use scalp acupuncture or syringe needle and replace, so not only can cause the air filtered directly to enter liquid, and increase patient's financial burden.
Summary of the invention
The purpose of this invention is to provide a kind of air pollution and more reliable and effective bottle stopper puncture needle of puncture procedure of not being subject to.
Technical scheme of the present invention is: comprise puncture needle and exhaustor, the exhaustor middle part is provided with pipe clamp, and the puncture needle outer surface is the frosted shape.
Because exhaustor of the present invention is provided with pipe clamp, can take ventilation or choke measure easily, promptly can implement the break-make of gas exhaust piping easily by pipe clamp, play the air-polluting effect that stops.The outer surface of puncture needle is the frosted shape, has increased frictional force, and puncture needle is difficult for withdrawing from after inserting bottle stopper, has improved the reliability of puncture, has also reduced the secondary pollution of liquid simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not constitute any limitation of the invention.
Fig. 1 is the three-dimensional installation diagram of the embodiment of the invention.
The specific embodiment
Shown in Figure 1, the present invention includes puncture needle and exhaustor 1, exhaustor 1 middle part is provided with pipe clamp 2, and the outer surface of puncture needle is the frosted shape.During use, when needs stop exhaustor 1 ventilation, pipe clamp 2 is clamped exhaustor 1 can stop air pollution.After puncture needle thrusts bottle stopper, produce big frictional force between frosting on the puncture needle and the bottle stopper, puncture needle is difficult for rebounding out, has reduced the chance of secondary pollution.
Claims (1)
1. a bottle stopper puncture needle comprises puncture needle and exhaustor (1), and exhaustor (1) middle part is provided with pipe clamp (2), and the puncture needle outer surface is the frosted shape.
