Description
Technical field
This utility model relates to a kind of transfusion device, especially a kind of disposable use child precision infusion set.
Background technology
Adult's blood capillary is generally 6um-8um; Child particularly infant blood capillary is generally thinner, and general transfusion device is regardless of the adult in infusion process, the child uses, no liquid medicine filter; Microgranule in the medicinal liquid does not have filter effect; Bigger microgranule can directly cause the local circulation obstacle to cause blood vessel embolism, and severe patient causes local the obstruction and the oxygen supply deficiency, and histanoxia produces edema and inflammation; Then can directly cause thrombosis or volume increased than small particle because foreign body intrusion tissue causes erythrocyte to focus on microgranule with blood flow; Cause granuloma; And, human body is damaged, and when transfusion because how quantity can cause blood vessel embolism equally; The air that gets in the transfusion device often contains micronic dust and antibacterial, and human body is damaged.At present, good solution is not also arranged.
The utility model content
The technical assignment of this utility model is to above-mentioned deficiency of the prior art a kind of disposable use child precision infusion set to be provided; This disposable use child precision infusion set has and is provided with two medicinal liquid accurate filters, the microgranule in the medicinal liquid is filtered good filtration effect; Be provided with air filter and check valve; Adsorbable airborne micronic dust and antibacterial, and prevent that medicinal liquid is back in the air filter or the outflow air filter, can guarantee the characteristics of the lasting ventilation of air filter.
This utility model solves the technical scheme that its technical problem adopted: it comprises bottle plug puncture unit, dropping funnel, flow regulator and intravenous needle; Described bottle plug puncture unit, dropping funnel, flow regulator and intravenous needle are connected through pipeline successively; Be disposed with the first medicinal liquid accurate filter and the second medicinal liquid accurate filter on the pipeline between described dropping funnel and the flow regulator; The pore size filter of the described first medicinal liquid accurate filter is 5um; The pore size filter of the described second medicinal liquid accurate filter is 0.2um-3um, and the bottom of described bottle plug puncture unit is provided with air filter, and the material of described air filter is a politef; The pore size filter of described air filter is 0.2um, is provided with check valve between described air filter and the bottle plug puncture unit.
Be respectively arranged with the automatic vent hole on the described first medicinal liquid accurate filter and the second medicinal liquid accurate filter.
Be respectively arranged with filter membrane between the described automatic vent hole and the first medicinal liquid accurate filter and the second medicinal liquid accurate filter, described filter membrane is a poly (ether sulfone) film.
The housing of described bottle plug puncture unit, flow regulator, the first medicinal liquid accurate filter, the housing of the second medicinal liquid accurate filter and the housing of air filter are processed by acrylonitrile-butadiene-styrene copolymer, and dropping funnel and pipeline are processed by polyolefins thermoplastic elastomer.
The disposable use child precision infusion set of this utility model is compared with prior art, has following outstanding beneficial effect: be provided with two medicinal liquid accurate filters, the microgranule in the medicinal liquid is filtered; Good filtration effect; Be provided with air filter and check valve, adsorbable airborne micronic dust and antibacterial, and prevent that medicinal liquid is back in the air filter or the outflow air filter; Can guarantee the lasting ventilation of air filter; Transfusion device adopts the medical macromolecular materials of non-PVC, to the human non-toxic side effect, and characteristics such as easy to use.
