Abstract
The utility model discloses a precise infusion tube filter, which belongs to the field of infusion filter technology. The main points of the technical scheme of the utility model comprise: the filtercomprises a shell; a secondary vent for guaranteeing infusion safety is arranged on the shell, wherein, the shell on the periphery of the secondary vent is provided with a convex ring and a sealing cover is arranged on the periphery of the convex ring. The utility model has the advantages of simple structure and convenient use and production, can prevent dropping phenomena when transfusion puncture is processed, and can be used for filtering liquid medicine of the infusion.
Description
Technical field
This utility model relates to a kind of filter, and more particularly, it relates to the effective filter of a kind of precision transfusion.
Background technology
Venous transfusion is as one of main means of clinical treatment, and its quality has direct influence to transmission of disease.In infusion process, infusion reaction happens occasionally, except that germ contamination reaction, pyrogen reaction, the particle contamination reaction that particulate matter causes also more and more is subject to people's attention, therefore, traditional precision infusion set is exactly to have increased liquid medicine filter on the basis of original common transfusion pipe, in order to guarantee the safety of infusing, also is provided with the secondary passage on filter housing.Also just because of the secondary passage that on filter housing, is provided with, medical personnel when carrying out the human body puncture, puncture draw point dropping liquid ceaselessly after pulling out needle guard, dropping liquids such as needs stop just to puncture, and are inconvenient to very much operate, and waste time.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, easy to use, can prevent the effective filter of precision transfusion that dropping liquid produces.
The technical solution of the utility model is such: the effective filter of a kind of precision transfusion, comprise shell, on shell, be provided with the secondary passage that guarantees transfusion safety, wherein, the housing of described secondary passage periphery is provided with protruding circle, is provided with seal cover in protruding circle periphery.
In the above-mentioned effective filter of a kind of precision transfusion, described seal cover can be adopted as soft material; Also can be adopted as hard material, but preferably can between seal cover and protruding circle, sealing gasket be set, to guarantee sealing effectiveness.
In the above-mentioned effective filter of a kind of precision transfusion, described seal cover side can also be hinged by brace and housing, more convenient like this operation.
This utility model utilizes seal cover to block the secondary passage after adopting said structure, and air advances less than in the filter, and when puncture, piercing needle just the ceaselessly situation of dropping liquid can not occur, not only makes things convenient for medical personnel to operate, and saves time.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing this utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of this utility model specific embodiment 1;
Fig. 2 is the structural representation of this utility model specific embodiment 2;
Fig. 3 is that embodiment 1 seal cover unplugs the structural representation that is;
Fig. 4 is a user mode sketch map of the present utility model.
Among the figure: shell 1, secondary passage 2, sealing plug 3, protruding circle 4, plastics needle for inserting bottle 5, Morphis tube 6, flow regulator 7, puncture draw point 8.
The specific embodiment
Consult Fig. 1, shown in Figure 3, the effective filter of a kind of precision transfusion of the present utility model, comprise shell 1, on shell 1, be provided with the secondary passage 2 that guarantees transfusion safety, also the housing 1 of secondary passage 2 peripheries is provided with the protruding circle 3 of annular, be provided with seal cover 4 in protruding circle 3 peripheries, seal cover 4 in the present embodiment is soft material manufacturings such as sanitary rubber, can guarantee sealing effectiveness, the effect of seal cover 4 is to stop in the air admission shell 1 in when puncture, thereby produces the long-time dropping liquid phenomenon that hinders medical personnel's operation when effectively avoiding the draw point puncture; Seal cover 4 sides are hinged by brace 6 and housing 1; Need like that seal cover 4 is unpluged shown in the image pattern 3 during normal infusion.
Consult shown in Figure 2, the effective filter of another kind of precision transfusion of the present utility model, substantially the same manner as Example 1, do not exist together is that seal cover 4 is hard materials such as health level plastics, for guaranteeing sealing effectiveness, between seal cover 4 and protruding circle 3, be provided with sealing gasket 5, its effect is basic identical with embodiment 1.
During concrete the use, consult shown in Figure 4, earlier needle for inserting bottle 7 is inserted in the infusion bottle, again with flow regulator 9 close Morphis tubes 8, be adjusted to the fluid stopping state then, push up emptying gas of Morphis tube 8, liquid in the infusion bottle is flowed into and be full of space between the fluid stopping point of Morphis tube 8 bottoms and actuator 9, regulate flow regulator 8, make liquid past dirty, by the microgranule in the accurate filter filter liquide, it is irritated to reduce transfusion, improves therapeutic effect, and liquid continues toward dirty, following gas is discharged from puncture draw point 10, during puncture, because full of liquid in the sebific duct, and the 2 usefulness seal covers 4 of the secondary passage on the accurate filter shell 1 are blocked, air can't enter, therefore ceaselessly dropping liquid phenomenon can not occur, medical personnel can make things convenient for, carry out the human body puncture quickly, after puncture is finished, pull out the seal cover 4 on the filter housing 1, can normally infuse.
