Disposable light-proof intravenous nutrition infusion bag

Abstract

The present invention provides a disposable light-proof intravenous nutrition infusion bag. The disposable light-proof intravenous nutrition infusion bag comprises a light-proof infusion bag and an infusion catheter, a hanging hole for hanging the light-proof infusion bag is formed at an upper side of the light-proof infusion bag, an upper end of the infusion catheter communicates with the light-proof infusion bag, the infusion catheter comprises an outer layer tube and an inner layer tube, the outer layer tube sleeves an outer side of the inner layer tube, the outer layer tube and the inner layer tube are fixed relatively, light-proof substances are coated on an outer side of the outer layer tube, a precise filter for filtering large granular substances is arranged on the infusion catheter, an exhaust protective cap is arranged at a tail end of the infusion catheter, a head end of the exhaust protective cap is inwards sunken to form an exhaust hole, and a PTFE filter membrane is arranged on a step of the exhaust hole. In the provided disposable light-proof intravenous nutrition infusion bag, the used bag body has a light-proof function, is free of light-proof substances, can be directly contacted with medicines, and is high in safety and low in costs, the infusion catheter has a light-proof function, the light-proof substances are added on the outer layer and cannot penetrateinto the inner layer, so that the disposable light-proof intravenous nutrition infusion bag is high in safety and low in costs.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable light-proof intravenous nutrition infusion bag. Background technique [0002] The current general intravenous nutrition infusion bag has the following disadvantages: ①The bag body does not contain light-proof function; ②The infusion line does not contain light-proof and precision filtering functions; ③After a long-term infusion with the infusion pump, the line is squeezed and deformed and cannot be recovered , which seriously affects the accuracy of infusion; ④The end of the pipeline is not closed and exposed to the air, so it cannot maintain a sterile state. When the pipeline is exhausted, medical staff need to continue to observe, and part of the liquid medicine is wasted during the exhaust process. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the...
