Problems solved by technology

However, since ordinary disposable infusion sets do not have an automatic closing mechanism, once the infusion is completed and the needle is not pulled out in time, it will cause blood backflow or air in the pipeline to enter the patient's vein, which can cause blood coagulation embolism, and in severe cases life threatening
Simultaneously because of this kind of reason, patient and medical staff must pay close attention to whether transfusion is finished all the time, so that pull out needle in time, bring tense pressure to patient and medical staff

Embodiment Construction

[0011] Below in conjunction with accompanying drawing description and specific embodiment, the present invention will be described in further detail:

[0012] see figure 1 , an infusion set with a floating stopper, comprising a stop clamp 1, a drip tube 2 and a flow regulator 3, a limit ring 4 is arranged inside the drop tube 2, and a cone is installed under the limit ring 4 Shaped limit sleeve 5, between the limit ring 4 and the limit sleeve 5 is provided with an ingot type or spherical floating plug 6, the maximum width of the floating plug 6 is greater than that between the two sets of walls of the limit sleeve 5 shortest distance.

[0013] The use process of the present invention is: connect the bottle insertion needle of the infusion set with the medicinal liquid, the medicinal liquid flows into the dripping tube 2 through the catheter, and then flows into the dripping tube 2 through the gap between the limiting sleeve 5 and the floating plug 6 At the lower end, when th...

Abstract

An infusion device with a floating plug includes a stop clip, a dropping tube and a flow quantity regulator and is characterized in that a limit ring is arranged in the dropping tube, a limit sleeve is arranged below a limit ring, and the floating plug is arranged between the limit ring and the limit sleeve. The maximum width of the floating plug is greater than the minimum distance between two sleeve walls of the limit sleeve, the limit sleeve is conical in shape, and the floating plug is in a shape of a shoe-shaped gold ingot or ball.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion set with a floating stopper. Background technique [0002] At present, in the medical and health field, disposable infusion sets are widely used to carry out intravenous infusion to patients, which has the advantages of convenient operation of intravenous administration, improvement of curative effect, disposable use, and positive effects of preventing cross-infection. However, since ordinary disposable infusion sets do not have an automatic closing mechanism, once the infusion is completed and the needle is not pulled out in time, it will cause blood backflow or air in the pipeline to enter the patient's vein, which can cause blood coagulation embolism, and in severe cases life threatening. Simultaneously because of this kind of reason, patient and medical staff must pay close attention to whether transfusion is finished all the time, so that pull out need...
