Problems solved by technology
When this kind of light-proof infusion tube is used, the light-proof additives in it will fall off, enter the liquid medicine, reduce the efficacy of the medicine, and even be brought into the human body by the liquid medicine, causing damage to the human body, and the use safety is low
[0003] In addition, most of the infusion sets currently on the market are made of medical-grade polyvinyl chloride (PVC), and some toxic additives and plasticizers are added during the manufacturing process of PVC, which will ooze or vaporize , some of the additives can interfere with biological endocrine, affect reproductive function, and some additives can cause cancer
During the infusion process, these toxic substances may enter the human body along with the drug, causing health hazards

Embodiment Construction
[0012] Such as figure 1 As shown, the double-layer casing type light-proof infusion set mainly includes an infusion tube 3 , a venous needle 1 , a drip funnel 2 , a flow rate regulator 4 and a puncture device 7 .
[0013] Its infusion tube 3 is made up of the inner tube 31 that does not contain plasticizer non-PVC flexible plastics, the outer tube 32 that light-proof material makes, and the outer tube 32 is sealed outside the inner tube 31.
[0014] The dropping funnel 2 is composed of an inner layer 21 made of non-PVC material without plasticizer and an outer layer 22 made of a light-proof material, and the outer layer 22 is hermetically coated outside the inner layer 21 .
[0015] The infusion tube between the dripping funnel 2 and the flow rate regulator 4 of the double-layer casing type light-proof infusion set is provided with a precision filter 6; the precision filter 6 is sealed and coated with an outer layer 61 made of light-proof material .
[0016] The infusion tub...

The invention relates to a double-layer sleeve-type light-shielding transfusion device, belonging to a medical appliance. The transfusion device comprises a transfusion tube, a venous needle, a dripping bucket, a flow rate adjuster and a puncture device and is characterized in that the transfusion tube is composed of an inner tube made of non-PVC (polyvinyl chloride) soft plastic free of plasticizer and an outer tube made of a light-shielding material, the outer tube is coated outside the inner tube in a sealing manner, the dripping bucket is composed of an inner layer made of non-PVC soft plastic free of plasticizer and an outer layer made of a light-shielding material, and the outer layer is coated outside the inner layer in a sealing manner. According to the invention, a double-layer sleeve-type design is adopted, the light-shielding requirements of the medicine are met by the light-shielding action of the outer tube, light-shielding additive granules are prevented from entering a medicine liquid and the use is safe; and at the same time, the inner tube of the transfusion tube can effectively prevent plasticizer and other toxic substances from harming a human body, and the patient health and safety are guaranteed to the greatest extent.
Description
technical field [0001] The invention relates to a medical infusion set, in particular to an infusion set for transporting medicine under the condition of avoiding light. Background technique [0002] At present, some drugs must be used under the condition of avoiding light clinically, such as some chemotherapy drugs, which cannot meet the requirement of protecting against light by using ordinary infusion sets to deliver such drugs. In order to solve this problem at present, the measures taken are to add light-shielding additives (mostly adopt carbon powder) in the infusion tube raw materials, and extrude after mixing to form a light-proof infusion tube. When this light-proof infusion tube is in use, the light-proof additive therein will fall off, enter the medicinal liquid, reduce the efficacy of the medicine, and even be brought into the human body by the medicinal liquid, causing damage to the human body, and the use safety is low. [0003] In addition, most of the infusi...
