Problems solved by technology

[0003] In order to overcome the current infusion sets used in clinical air-intake infusion, only a hydrophobic membrane with a pore size of ≤0.45 μm is installed on the air-intake device to prevent the liquid from flowing out through the air-intake device and to filter the air, preventing microorganisms from entering the liquid-medicine container, but the pore size is ≤ The 0.45μm hydrophobic membrane cannot filter out and prevent harmful substances in the air such as sulfur compounds, nitrogen oxides, and volatile organic compounds from entering the liquid medicine container, dissolving into the liquid medicine and entering the human body, endangering human health.

Embodiment Construction

[0008] The air-purifying infusion set of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0009] Such as figure 1 The air-purifying infusion set of the present invention is connected and penetrated by a cork piercer (1), an air intake device (2), a drip funnel (3), a filter (4), an infusion tube (6), and a venipuncture needle (5). , the infusion tube (6) is sleeved with a flow regulator (7), and the air intake device (2) is first covered with a hydrophobic membrane (8) with a fixed aperture ≤ 0.45 μm, and then covered with a membrane (cloth, felt, etc.) woven from fixed activated carbon fibers. , paper) (9) composition, it is characterized in that: be provided with the film (cloth, felt, paper) (9) that activated carbon fiber is woven into at air intake device (2). In air-intake infusion, the air is a membrane (cloth, felt, paper) (9) woven by activated carbon fibers, and a hydrophobic membrane (8) with a p...

Abstract

The invention provides an air purification infusion device. In the device, a plug puncture set, an air inlet device, a dropping funnel, an infusion tube, a filter and a venipuncture needle are connected and communicated, and a flow rate regulator is sleeved on the infusion tube; and a hydrophobic membrane with a pore diameter of less than or equal to 0.45mu m and a membrane (fabric, felt and paper) woven by activated carbon fibers are covered and fixed on the air inlet device in turn. The air purification infusion device is characterized in that: the air inlet device is provided with the membrane (fabric, felt and paper) woven by the activated carbon fibers. When air inlet type infusion is carried out, air passes through the membrane (fabric, felt and paper) woven by the activated carbon fibers and the hydrophobic membrane with the pore diameter of less than or equal to 0.45mu m to filter out microbes, sulfur-containing compounds, oxynitride, volatile organics and other harmful substances, and then enters a liquid medicine vessel.

Description

technical field [0001] The invention belongs to a medical device, in particular to an air-purifying infusion set for infusion. Background technique [0002] At present, the infusion set used in clinical air-intake infusion is only provided with a hydrophobic membrane with a pore size of ≤0.45 μm on the air intake device to prevent the outflow of the liquid medicine through the air intake device, and to filter the air to prevent microorganisms from entering the liquid medicine container, but the pore size is ≤0.45 μm. The μm hydrophobic membrane cannot filter out or prevent harmful substances in the air such as sulfur compounds, nitrogen oxides, and volatile organic compounds from entering the liquid medicine container, dissolved in the liquid medicine, and entering the human body, endangering human health. Contents of the invention [0003] In order to overcome the current infusion sets used in clinical air-intake infusion, only a hydrophobic membrane with a pore size of ≤...
