Abstract
The utility model relates to the field of medical instruments, and discloses an infusion set with double-layer filtering, bidirectional automatic air exhausting, automatic liquid checking and blood return preventing functions. The infusion set is composed of a double layer filtering membrane, floating plates, an upper cover, and a lower cover. The upper cover comprises two symmetrical trapezoid bodies with a middle opening, and is covered by a filtering membrane. The upper ends of the trapezoid bodies are provided with the floating plates, and one side of each trapezoid body is provided with a normal infusion channel. The shape of the lower cover portion is special. Six symmetrical apertures are arranged near the edge of the upper portion of the lower cover, which provides convenience for liquid to flow out. The lower portion of the lower cover is convex-shaped with the four sides lower than the middle portion, which also provides convenience for liquid to flow out.
Description
Technical field
This utility model relates to the medical apparatus and instruments category, specifically is a kind of double medium filtration, two-way automatic vent, ends the infusion set of liquid, blood return prevention automatically.
Background technology
Transfusion device on the market mainly contains 2 kinds now, and a kind of is plain edition, does not filter or filter the above granule of 15 μ m, and another kind is accurate, can filter the above granule of 5 μ m.
The precision infusion set filtering function still can, but stop up easily.
The utility model content
Much have at present the filter membrane transfusion device all to face the problem of an aerofluxus, this device adopts two-way automatic vent, can reach effect preferably.Only liquid, blood return prevention also are resolved simultaneously.
The purpose of this utility model is achieved in that
A kind of double medium filtration, two-way automatic vent, end the infusion set of liquid, blood return prevention automatically, formed by loam cake, lower cover, filter membrane; It is trapezoidal that loam cake is symmetry, and loam cake is made up of loam cake filter membrane, first gas passage, kickboard, second gas passage, blood return prevention hole, loam cake substrate, loam cake normal infusion passage, loam cake inwall, last cover outer wall; Lower cover is made up of lower cover substrate, transfusion duct, arcwall face, infusion channel; Between loam cake and the lower cover filter membrane is arranged.
The kickboard that is positioned at the loam cake upper end is thin film or thin plastic sheet; The aperture of loam cake filter membrane is 10-15 μ m; The aperture of filter membrane is for equaling 10 μ m or less than 5 μ m.
The contained transfusion of lower cover duct is outstanding downwards, prevents that liquid in the middle of the initial transfusion stage flows to, is unfavorable for aerofluxus; Arcwall face totally is middle high, low all around, and the center part is downward; Infusion channel projects upwards.
At first, when medicinal liquid when the dropping funnel, because of on covered one deck filter membrane, realized filtering first, bigger because of the filter membrane aperture, can not form obstruction; In medicinal liquid enters loam cake, because of loam cake and lower cover intermediate filtered film for dredging air film, air is pressed towards loam cake top naturally, pore is arranged at top, and kickboard is light material, and gas is discharged automatically, after gas was discharged, kickboard descended because of action of gravity, and sealed porosity forms normal infusion automatically.Medicinal liquid flows to lower cover behind upper and lower cover intermediate filtered film, the lower cover periphery has the transfusion duct, outstanding slightly downwards, thereby medicinal liquid can not flow to middle, when liquid after lower cover periphery is assembled, in the middle of upwards flowing to, the infusion channel that projects upwards has slightly also been striven for the time for oppressing gas automatically, so again can automatic vent.
When dropping funnel upper end does not have fluid drips following time, kickboard and film form the relative closure space, outside gas is difficult for entering, and pin down down capillary simultaneously, and medicinal liquid can be slowly by the blood return prevention hole.Form and end liquid, blood return prevention automatically.
Description of drawings
Concrete structure of the present utility model is by following accompanying drawing and embodiment explanation.
Fig. 1 is the profile of this infusion set.
The specific embodiment
Describe details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with Fig. 1.
This infusion set comprises a kind of multifunctional filtering infusion set of being made up of loam cake 1, lower cover 16, filter membrane 15.It is trapezoidal that loam cake 1 is symmetry, and loam cake 1 is made up of loam cake filter membrane 3, first gas passage 4, kickboard 5, second gas passage 6, blood return prevention hole 7, loam cake substrate 8, loam cake normal infusion passage 9, loam cake inwall 10, last cover outer wall 11; Lower cover 16 is made up of lower cover substrate 17, transfusion duct 18, arcwall face 19, infusion channel 20.Filter membrane 15 is arranged between loam cake and the lower cover.
Be example with Fig. 1, medicinal liquid enters dropping funnel through needle for inserting bottle 12 and conduit 13 during work, after filtering, loam cake filter membrane 3 enters in the loam cake 1, medicinal liquid is oppressed air naturally and is upwards washed kickboard 5 open, discharges automatically through second gas passage 6, after not having gas pressure, kickboard 5 descends naturally, cover first gas passage 4, form confined space, medicinal liquid enters filter membrane 15 through loam cake normal infusion passage 9, and the transfusion duct 18 that enters lower cover 16 downwards is gathered in the periphery back by arcwall face 19, arrive infusion channel 20, form automatic vent.
After transfusion stopped, loam cake 1 part had covered first gas passage 4 because of kickboard 5, formed confined space, thereby formed only liquid effect, and simultaneously, residual liquor forms tension force upwards at loam cake filter membrane 3, filter membrane 15 in the loam cake 1; With downward gravity relative equilibrium, form the trace transfusion, 7 flow out through the blood return prevention hole, reach the blood return prevention effect in the certain hour.
