Abstract
The utility model provides a dripping hopper filter of a large-flow infusion apparatus. A dripping hopper is combined by an upper cover and a base, the base is arranged on the lower portion of the upper cover and provided with a liquid outlet channel, a groove matching with the side wall of the upper cover is arranged on the side wall of the liquid outlet channel, the side wall of the upper cover is inserted in the groove and hermetically connected with the groove, a barrel-type filter element is disposed in the dripping hopper and comprises a filter layer, an upper end plate, a center perforated tube and a lower end plate, the filter layer is arranged outside the center perforated tube, and is closely sealed with the upper end plate and the lower end plate up and down after being in edge sealed, and the lower end plate is provided with a hole communicated with the liquid outlet channel of the base. The filter element is arranged in the dripping hopper of the dripping hopper filter, so that filter area is greatly increased in a limited space, filter quantity is added, side leakage is avoided, safety, reliability and certain economical efficiency are guaranteed, the infusion apparatus is not required to be replaced frequently, and accordingly the dripping hopper filter is particularly applicable to realizing infusion of easy-blocking liquid medicine such as Chinese herba preparation.
Description
Technical field
This utility model relates to the medical apparatus and instruments that clinical transfusion is used, and especially relates to a kind of dropping funnel filter of big flux transfusion device.
Background technology
The transfusion device of clinical use is made up of bottle plug puncture unit and protective sleeve, exhaust apparatus, transfusion upper conduit, dropper, dropping funnel, liquid medicine filter, pipeline, flow regulator and injection member.The medicine filter is located in the dropping funnel, forms by filter membrane being fixed on the dropping funnel bottom usually.The membrane filtration amount of filter is smaller, can stop up when filtering Chinese medicine preparation, makes that flow is too small and transfusion is very slow, can not adapt to many bottles of transfusions, thereby cause waste, and increase nurse's workload.The filter membrane ratio is easier to take place to become flexible simultaneously, thereby causes side leakage, influences filter effect, and causes bubble to enter infusion pipeline easily.
Publication number is that the application for a patent for invention of CN101791444A discloses a kind of safe bubble-free infusion set, employing covers the installation gas deflation assembly at dropping funnel, in the dropping funnel bottom safe bubble-free assembly is installed, the safe bubble-free assembly is made up of common liquid medicine filtering membrane, precision liquid medicine filter membrane and medicinal liquid base, common liquid medicine filtering membrane, precision liquid medicine filter membrane are fixed in the medicinal liquid base, and wherein common liquid medicine filtering membrane is positioned at precision liquid medicine filter membrane upper strata.Safe bubble-free assembly in this technical scheme is that filter exists the sealing difficulty, the problem of easy side leakage, and same processing assembling is also relatively more difficult.
Summary of the invention
This utility model provides a kind of dropping funnel filter of big flux transfusion device, and this dropping funnel filter filtration yield is big, side leakage free, the transfusion of particularly suitable Chinese medicine preparation.
A kind of dropping funnel filter of transfusion device is combined to form dropping funnel by loam cake, base, and described loam cake bottom is provided with base, and described base is provided with liquid outlet channel, and sidewall is provided with the groove that cooperates with the sidewall of loam cake, and the sidewall of loam cake inserts in the groove and is tightly connected; Be provided with cylindrical filter cartridge in the described dropping funnel, described cylindrical filter cartridge comprises filtering layer, goes up dististyle, center antipriming pipe, lower end-piece, and described filtering layer is located at outside the antipriming pipe of center, behind the banding with last dististyle, lower end-piece up and down driving fit seal; Described lower end-piece is provided with the hole that is communicated with the liquid outlet channel of base.
Described filtering layer is made up of monofilm, but also filtering layer forms by monofilm and water conservancy diversion layer are folding.
Described monofilm is accurate microporous filter membrane or common filter membrane.Adopt accurate microporous filter membrane, the aperture is in 5 microns.
Described filtering layer is collapsible core structure, sintered type structure or melts and sprays multiple structure.
The lower end-piece of described cylindrical filter cartridge adopts adhesive-free to engage with base, for example adopts high-temperature fusion, welding etc.
This utility model is provided with filtering filter element in dropping funnel, increased the area of filter course greatly, has strengthened filtration yield.The transfusion of picture Chinese medicine preparation class because its medicinal liquid viscosity is big, and has tiny granule, is stopped up easily.Therefore be particularly suitable for adopting dropping funnel filter of the present utility model to filter, do not need frequently to change transfusion device in the infusion process, save the transfusion cost, also reduced nurse's workload.

The specific embodiment
As shown in Figure 1, 2, transfusion device is made up of bottle plug puncture unit protective sleeve 1, bottle plug puncture unit 2, exhaust apparatus 3, transfusion upper conduit 4, dropper 5, loam cake 6, cylindrical filter cartridge 7, base 8, infusion pipeline 9, flow regulator 10 and injection member 11.
Dropping funnel inside is provided with cylindrical filter cartridge 7, and cylindrical filter cartridge is 7 to be formed by the 74 assembling driving fits of last dististyle 71, center antipriming pipe 72, lower end-piece 73, filtering layer, and filtering layer 74 is located at outside the center antipriming pipe 72, behind the banding with last dististyle 71, lower end-piece about in the of 73 driving fit seal.Described driving fit can adopt the mode of adhesive-frees such as fusion, welding to carry out.
After the lower end-piece 73 and the base 8 of cylindrical filter cartridge 6 carried out driving fit, the groove 81 that again loam cake 6 is inserted the cooperation of base 8 sidewalls carried out adhering and sealing.
Filtering layer 64 in the filter element 6 can adopt monofilm to make, and also can be monofilm and the water conservancy diversion layer is compound makes.Monofilm can adopt the aperture to make at the accurate microporous filter membrane such as for example polyether sulfone PES film below 5 microns, can also be that the common filter membrane of the super fine fibre of conventional polypropylene is made.
Medicinal liquid flows in the dropping funnel filter through dropper 5 by transfusion catheter 4, filters in inflow center, the back antipriming pipe 72 through the filtering layer in the cylindrical filter cartridge 7 74, and the liquid outlet channel 82 in base 8 flows out, and enters in the infusion pipeline 9.
