Abstract
The utility model relates to the field of medical devices, and particularly to a multifunctional transfusion device for soup filtering, automatic air exhausting, automatic soup stopping and blood backstreaming preventing. The multifunctional transfusion device is mainly characterized in that the filter is composed of an upper cover, a base and a filtering film. The upper cover is composed of two channel pipes. A long pipe is used for exhausting air, and a short pipe is a normal soup conveying channel. The bottom of the upper cover is provided with a small hole which slightly project downwards, thereby performing functions of automatic air exhausting, automatic soup stopping and blood backstreaming preventing. Water can pass through the filtering film and air can not pass through. The base is semicircular. The pipe wall of a transfusion channel is provided with four rectangular grooves for facilitating automatic air exhausting and transfusion.
Description
Technical field
This utility model relates to the category of medical apparatus and instruments, is the infusion set of a kind of Multifunctional medicinal liquid filtration, automatic vent, automatic liquid-stopping, blood return prevention.
Background technology
Now the kind of transfusion device mainly contains 2 kinds, and a kind of is plain edition, and not with filter or filter microgranules more than 15 μ m, another kind is accurate, can filter the above granule of 5 μ m.
Have in the market the disc filter of exhausting window and the defecator that dropping funnel is windowed, these 2 kinds of modes all can not solve the problem of automatic vent and automatic liquid-stopping, blood return prevention.
Utility model content
The purpose of this utility model is to provide a kind of infusion set of multifunctional medicine liquid filter, and liquid medicine filter has filter particulates, automatic vent, automatic liquid-stopping and blood return prevention several functions simultaneously like this.
The purpose of this utility model is achieved in that
An infusion set for Multifunctional medicinal liquid filtration, automatic vent, automatic liquid-stopping, blood return prevention, is comprised of upper cover, base, filter membrane; Upper cover is by infusion channel pipe, and manage exhaust passage, blood return prevention hole, and upper cover inwall, outer wall forms; Upper cover is connected by filter membrane with base, and infusion channel pipe, exhaust passage Guan Jun are positioned at cover rim, has only liquid, blood return prevention hole in the middle of upper cover, in the middle of upper cover inwall and upper cover outer wall, is space, is convenient to install dropping funnel; Base is semicircle, and mid portion is infusion channel pipe top closure, and medicinal liquid and gas enter tube for transfusion downcomer by four rectangle grooves, and the diameter of liquid medicine filtering membrane is 14-21mm.
Infusion channel room, pipe top, exhaust passage are inclined plane, are convenient to aerofluxus and water inlet, 30 ° of-60 ° of angles of gradient; Base is semicircle, is convenient to aerofluxus; Lower cover intermediate exhaust, infusion channel tube wall have four rectangle grooves, are convenient to air exhausting transfusion.
Groove is rectangle, length 3mm-12mm, wide 1mm-5mm.
The infusion set of Multifunctional medicinal liquid filtration, automatic vent, automatic liquid-stopping, blood return prevention is for directly filtering to formula.First, when medicinal liquid when the dropping funnel because the infusion channel of upper cover is difficult for producing bubble with exhaust passage Guan Jun near dropping funnel wall, when medicinal liquid reaches the top height of infusion channel pipe, liquid produces pressure, and air pressure is managed to the exhaust passage of same pedestal.Reach automatic vent, medicinal liquid, through filter membrane, reaches and filters after object, enter base, base center-aisle You Si road groove, medicinal liquid is assembled at this, gas integral body is pressed to lower end, form automatic vent, after medicinal liquid is totally lost, upper cover liquid does not have pressure, to flow down by aperture in the middle of upper cover, because middle aperture is connected with film, liquid forms by filter membrane make progress tension force and gravity and reaches relative equilibrium, form micro-infusion mode, reach automatic liquid-stopping and blood return prevention effect.
So it is relatively simple that Multifunctional medicinal liquid filters automatic vent, the infusion set of automatic liquid-stopping blood return prevention, structure, cost is relatively cheap.
Accompanying drawing explanation
Concrete structure of the present utility model is illustrated by following accompanying drawing and embodiment.
Fig. 1 is according to the profile of the infusion set of the standby Multifunction of usual friendship.
The specific embodiment
Below in conjunction with Fig. 1, describe details and the working condition according to the concrete device the utility model proposes in detail.
The infusion set of Multifunctional medicinal liquid filtration, automatic vent, automatic liquid-stopping, blood return prevention comprises a upper cover 1, and it is by an infusion channel room 2, and exhaust passage manages 3, blood return prevention hole 9, and upper cover inwall 5, outer wall 6 form.Infusion channel room 2, exhaust passage pipe 3, all perpendicular to upper cover 1 bottom, are filter membrane 4 between upper cover 1 and base 7, base 7 semicirculars in shape, and center-aisle pipe 8 has four rectangle grooves.
Take Fig. 1 as example, and during work, liquid enters dropping funnel through needle for inserting bottle 11 and conduit 12, and liquid covered oppresses gas behind infusion channel pipe 2 tops and enter exhaust passage pipe 3, reaches aerofluxus.Liquid, through filter membrane 4 filter particulates, is reached filter effect.Liquid is through base 7 because base 7 is semicircle, and meanwhile, passage 8 has 4 grooves, and easily mineralization pressure, discharges gas integral body.Medicinal liquid and gas enter tube for transfusion downcomer 13 by four rectangle grooves.
When infusion bottle drips after sky, in dropping funnel 10, the residual liquid that upper cover 1 forms, through blood return prevention aperture 9 slow infiltration films 4, produces tension force on filter membrane 4, with liquid gravity relative equilibrium, forms micro-infusion mode, reaches automatic liquid-stopping, blood return prevention effect.
