The air inlet of the input end of an open type infusion container or the air inlet of the output end of a closed type infusion container is provided with an air disinfecting sterilizer for the air going into the container to conduct the disinfecting process; the air disinfecting sterilizer is composed of a sealing cover whose lower part is filled with the solid disinfectant and the filtered foam and a container whose upper part is filled with the sterilized solution. The utility model has the non-toxic and the sterile characters; the method of the utility model used for vein liquid treatment is safe; the air disinfecting sterilizer of the utility model can be arranged on the general medical injector, which can reach the non-toxic and sterile treatment effect.

Description

Sterile infusion device

This utility model is a kind of medical treatment device.

Before the utility model proposes, the infusion set of Shi Yonging has two types of enclosed and open types clinically.They all are made up of liquid container (or claim saline bottle) and the conduit or the syringe needle that are connected on the container, and what they were different is: the enclosed infusion set is that the input and output of liquid and the air intake that enters container all are arranged on same end; The open type infusion set is the upper end that the adding of liquid and the air intake that enters container is arranged on container, and the outfan of liquid is arranged on spill place, container lower end.These two kinds of infusion sets all have a common defective: not to entering air in the liquid container sterilization treatment that carries out disinfection, waited that the liquid of importing human body pollutes easily, produce bad medical effect, so that bring unnecessary sensual misery and loss economically to the patient.For example: the enclosed infusion set adopts the direct suck air of common air inlet syringe needle, and miscellaneous dust, pathogenic bacteria will together enter in the liquid container in the air, so that pollutes the liquid of waiting to import human body; The open type infusion set is an antiseptic gauze on the upper end of container feed liquor and air intake port cover, and this is to the filtration on the superficial phenomenon that enters of air, but still can not stop and be free in entering of the dust that is small molecule in the air and pathogenic microorganism.Simultaneously, the Soft flocks of antiseptic gauze, Cotton Gossypii also might fall in the infusion vessel, thereby pollute the liquid of waiting to import human body.Moreover the outfan of container is arranged on the spill place of the bottom minimum point of container, and all impurity greater than liquid ratio all can at first be imported (as glass granules, plastic particles, cotton yarn measuring fiber bits etc.) in patient's body.

In order to overcome the existing common defects of above-mentioned two class infusion sets, the inventor has designed a kind of infusion set that has the air sterillization steriliser, this infusion set not only can will enter the sterilization that carries out disinfection of air in the container, and can make container interior greater than the unlikely human body that enters of the impurity of liquid.

This utility model is at the input air inlet of open type infusion vessel or at the outfan air inlet place of enclosed infusion vessel an air sterillization steriliser to be set, with to entering air in the container sterilization treatment that carries out disinfection.

Fig. 1 is the sketch map of existing infusion set.

Fig. 2 is a sketch map of the present utility model.

Fig. 3 is the cutaway view of air sterillization steriliser of the present utility model.

In the accompanying drawings, Fig. 1 (a) is an open type infusion set of the prior art, and Fig. 1 (b) is an enclosed infusion set of the prior art.1 expression infusion vessel among the figure, 2 is that container cover and liquid add end and enters the interior air intake of container, 3 is transfusion catheter, 4 for waiting to import the liquid of human body in the container, 5 for entering the space of air in the container, 6 for entering the impurity in the container, and 7 is the air inlet syringe needle of enclosed infusion vessel; Fig. 2 (a) is an open type infusion set of the present utility model, and Fig. 2 (b) is an enclosed infusion set of the present utility model.8 is the transfusion container sealing pad among the figure, and 9 is convex container cover and the air intake handled through disinfection sterilization device, and 10 be the conduit of carrying air between infusion vessel and the disinfection sterilization device, and 11 is the air sterillization steriliser, and 12 is to the projecting inward glass tubule of container; Among Fig. 3,13 is the termination, gas outlet of disinfection sterilization device, in order to connect the air induction conduit or the air inlet syringe needle of infusion vessel, 14 is the rubber upper shield of termination, gas outlet, 15 is cleaned air passes, and 16 is sterilized liquid, and 17 is the sterilized solution container, 18 are rubber packing isolation and connection gasket, 19 is the space, and 20 is solid disinfecting agent, and 21 is seal cover, 22 is non-toxic foam, and 23,24 is air inlet.

In conjunction with the accompanying drawings embodiment of the present utility model is further described again below:

Air sterillization steriliser 11 of the present utility model is seal covers 21 that solid disinfecting agent 20 and filter foam 22 are housed by the bottom, and the container 17 that sterilized liquid 16 is housed with top is formed.Seal cover 21 usefulness glass and plastics are made, the interior non-toxic foam 22 of topped one deck 5 millimeters thick up and down of lid, middle active carbon 20 or other solid disinfecting agents of filling.The upper outer layer of air sterillization steriliser is made with glass, isolate and connection gaskets 18 composition sterilization containers 17 together with the rubber packings below the sterilized liquid 16, in volume is arranged is ethanol 16 or other sterilized solutions and the clearance space 19 of 1/2-2/3.Isolate connection gasket 18 and run through the air admission hole 23,24 that a diameter is the 0.5-5 millimeter with place, the low centre of lid, one air outlet slit termination 13 is arranged at the top of sterilization container 17, in order to connect conduit 10 or the air inlet syringe needle 7 of carrying air, the air behind the sterilization is carried or is inserted in open type or the enclosed infusion vessel 1 with air inlet syringe needle 7 through conduit 10.

Compared with prior art, outstanding feature of the present utility model is to have carried out strict sterilization and process entering air in the infusion vessel, and the liquid of human body to be entered is not polluted, and makes the intravenous fluids treatment safe and reliable and perfect. Simultaneously, also air sterillization sterilizer of the present utility model can be arranged on the medical general syringe, can reach equally the effect of nontoxic aseptic injection treatment.
