Embodiment

[0009] In the figure, 1 is a piercer, 2 is a drip funnel, 3 is a flow regulator, 4 is a precision filter membrane, 5 is an infusion tube, and 6 is a light-shielding layer.

[0010] During production, a layer of light-shielding layer 6 is attached to the inner wall of the dropping funnel 2 and the infusion tube, and the light-shielding layer 6 is insoluble in medicinal liquid.

[0011] When in use, due to the existence of the light-shielding layer 6, the light-shielding wavelength range of the light-shielding infusion set can be increased to 250-550nm, so that the medicinal solution can avoid the reaction caused by too strong light energy.

Abstract

The invention relates to a broadband light-proof infusion device. The broadband light-proof infusion device comprises a puncture outfit, an infusion tube, a dripping bucket and a flow regulator and is characterized in that light-proof layers are arranged on the infusion tube and the inner wall of the dripping bucket; and the light-proof wavelength of the light-proof infusion device ranges from 250 to 550 nm. The broadband light-proof infusion device has following beneficial effects: the range of the light-roof wavelength of the light-proof infusion device can be increased to 250-550nm so that lower light transmittance is obtained; and problems of an existing light-proof infusion device such as light-proof narrow range (290-450nm) and high light transmittance in order to satisfy the higher application demand of the light-proof infusion device.

Description

technical field [0001] The invention relates to a wide-band light-proof infusion set. Background technique [0002] At present, the clinically used infusion sets are mainly ordinary non-light-proof infusion sets, but many drugs have special molecular structures, which will absorb light energy under light, especially due to the high energy of light in the ultraviolet region, decomposition and oxidation occur and other reactions, leading to changes in the composition of the drug, reducing or losing its due curative effect; and changes in these components will also produce toxic substances harmful to the human body, causing serious adverse reactions to patients, such as photodegenerative reactions, phototoxic reactions, increased Risks to patient safety and even life-threatening. Therefore light-shielding infusion has become an indispensable treatment method, and the methods mainly adopted in China at present stage have two kinds of light-shielding cover and light-shielding in...
