Embodiment Construction

[0010] Such as figure 1 As shown, a safety infusion set includes an infusion tube 1, a funnel 2 and a needle. The infusion tube 1 is connected to the funnel 2 and the needle respectively, and a plastic foam float 3 is arranged in the funnel 2.

[0011] When in use, operate according to the operating procedures of the normal infusion set. At this time, the liquid in the funnel 2 connected to the infusion tube 1 will hold up the plastic foam floating ball 3. After the liquid in the funnel 2 has flowed out, the plastic foam floating ball 3 will Descend until the liquid outlet below the funnel is blocked, so that even if the needle is not pulled out in time, the blood in the blood vessel will not flow back into the infusion set.

Abstract

The invention relates to a safety infusion set which comprises a perfusion tube, a funnel and a pinhead. The perfusion tube is respectively connected with the funnel and the pinhead. A plastic foam floating ball is arranged in the funnel. As the structure is adopted, when the liquid in the funnel all comes out, the floating ball stems a liquid hole at the lower part of the floating ball, in this way even though the pinhead is not plucked off in good time, the blood in veins does not flow backwards into the infusion set, the purpose of safe use is achieved.

Description

technical field [0001] The invention relates to an improvement of a medical infusion tool, in particular to a safety infusion set. Background technique [0002] If the needle of the existing infusion set is not pulled out in time after use, the blood in the blood vessel will flow back into the infusion set, causing danger. Contents of the invention [0003] The purpose of the present invention is to provide a safety infusion set, which can overcome the above-mentioned deficiencies in the prior art, and make the use of the infusion set safer and more reliable. [0004] The object of the present invention is achieved like this: a kind of safety transfusion set, comprises transfusion tube funnel and needle, and transfusion tube is connected with funnel and needle respectively, and a plastic foam floating ball is arranged in funnel. [0005] Due to the above structure, when the liquid in the funnel runs out, the floating ball will block the liquid outlet at the lower part of ...
