For solving the problems of the prior art, the invention discloses following technical scheme:
The object of exhaustor (15) is the gas of deriving minute bubbles synthesis in gas collecting apparatus (3).
Filter (6) have employed a kind of novel high polymer polymeric material, and it utilizes charge forces, has adsorption to the microgranule such as antibacterial, endotoxin, completes large aperture (50 μm) filter bacteria and endotoxic function.
What wriggling region (4) adopted is composite, and internal layer is medical material PE etc.; Cladding material adopts the high-elastic silica gel of highly elastic material etc.; Adopt this material namely to ensure the elasticity of tube for transfusion, in turn ensure that infusion flow precision and conduit working life.
Heater (2) inside adopts floor, makes liquid form U-shaped flowing, allows liquid be full of utricule all the time, improves the efficiency of heating surface.Heater (2) is made up of special material, and internal layer is medical material Stainless steel 316 L, and cladding material smears elastic heat conducting silica gel etc.; Adopt this material namely to ensure heat conductivity, in turn ensure that fully contacting of transfusion device and calandria.Heater (2) adopts flat bellows structure, when cross-sectional area is certain, ensure that also contacts area.
The input of liquid collector of the present invention (1) connects many droppers; dripping (10) is wherein normal open; connect again when the dropper (11,12) of both sides needs; otherwise cover with protective cap; have two ribs in dropping funnel inside, (this transfusion device belongs to specialized transfusion system, coordinates can realize multichannel and be mixed in proportion transfusion with equipment to be used for preventing interference of light; with the flow velocity of each road pipeline of infrared detection, realize this function by feedback regulation).
Liquid collector (1) also comprises air filter (13).Primary filter (14) is had in the below of liquid collector (1), described gas collecting apparatus (3) object is that collection is along the bubble of tube wall and the issuable bubble of heating, bubble enters gas collecting apparatus (3) with medicinal liquid along feed liquor conduit, liquid flows into along ingress pipe (30) and flows out through (32), and bubble is then stayed in the chamber capsule of gas collecting apparatus (3).After collection and confinement of gases is a certain amount of, gas can flow into liquid collector (1) along with air vent (31) and exhaustor (15).
What wriggling region (4) adopted is composite, and internal layer is PE material. cladding material can select POE, TPU, PVC, SEBS, SBS etc.Adopt this tube for transfusion can improve the elasticity of tube for transfusion, the life-span of precision and the conduit of infusing can be ensured.
Compared with prior art, the invention has the beneficial effects as follows: multichannel combined transfusion can be realized; Infusion pump can be coordinated to realize multichannel infuse in proportion; Heated transfusion; Thermal energy efficiency can be improved; Can prevent from adding thermogenetic small amounts of gases enters people health with medicinal liquid.
