Abstract
The utility model discloses a self-exhausting liquid medicine filter, comprising a lower cover, an upper cover, a liquid medicine filtering membrane, an air plug and an air filtering membrane, wherein the air filtering membrane is thermally sealed on the exhaust slot hole of the upper cover, the liquid medicine filtering membrane is clamped between the upper cover and the lower cover, the joint surfaces of the upper and lower covers and the liquid medicine filtering membrane are thermally sealed, the air plug is adhered to the outer side of exhaust hole of the upper cover, the liquid inlet end of the upper cover is connected with the lower hose of the dripping bucket of an infusion apparatus, and the liquid inlet end of the lower cover is connected with the upper hose of the infusion apparatus; the self-exhausting liquid medicine filter is characterized in that the air plug is adhered to the outer side of the exhaust hole of the upper cover, when air enters into the lower hose of the infusion apparatus, the air in the lower hose of the infusion apparatus can be exhausted by opening the inner plug of the air plug, the infusion apparatus can still be sealed without leakage by inserting the inner plug, and the inner plug can be repeatedly opened and inserted. Thereby, the workload of medical staffs can be reduced, and medical staffs can conveniently and timely observe blood return when in puncturing, and thus the infusion is much safer.
Description
Technical field
This utility model relates to disposable use medical apparatus and instruments, especially relates to a kind of from exhaust liquid medicine filter.
background technology
The disposable infusion set of the clinical use of clinical unit of domestic each medical institutions, all is furnished with liquid medicine filter, on liquid medicine filter, be covered with exhausting window, to have facilitated to get rid of the air that enters dropping funnel below flexible pipe like this, but also give in clinical use and brought trouble and potential safety hazard, a lot of medical institutions by before puncture and venipuncture procedure separately carry out, as, can make Transfusion needle pipe not stop sepage, impact puncture inserting needle, in addition, as long in the dead time, medicinal liquid in the conduit of filter lower end can be walked sky, easily causes air to carry out human body; For preventing this problem, some manufacturers increase by a tongs on the flexible pipe of filter lower end, but and are difficult for finding to puncture, bringing inconvenience by blood back when having increased this tongs and making to puncture clinically.
utility model content
It is a kind of from exhaust liquid medicine filter that the purpose of this utility model is to provide, transfusion device assembles after this liquid medicine filter, without increasing tongs, can remove again and enter air in dropping funnel bottom hose, while puncturing, inserting needle does not affect, and can also find fast blood back, has so both facilitated medical personnel's operation, save time, the medical tangle that can avoid malpractice to cause again.
For achieving the above object, this utility model adopts following technical scheme: this utility model comprises lower cover, upper cover, liquid medicine filtering membrane, air lock and air-filtering membrane, air-filtering membrane is heat sealing on the aerofluxus notch of upper cover, liquid medicine filtering membrane is clipped between upper cover and lower cover, on, lower cover and liquid medicine filtering membrane composition surface heat seal sealing, air lock is bonded in row's mouth outside of upper cover, the inlet end of upper cover is connected with infusion unit titrimeter bottom hose, the liquid outlet end of lower cover is connected with transfusion device top hose, it is characterized in that: side bonds one tool plug air lock outside the air vent of upper cover, when entering after air in transfusion device bottom hose, open plug in air lock, can get rid of the air entering in transfusion device bottom hose, fill in Nei Sai and can make again its sealing without leakage, interior plug can repeatedly be opened and fill in.
Liquid medicine filtering membrane can be secondary filter film, can be also common filter membrane, and its membrane material can be plastics nucleopore thin film class film material or fibrous membrane material or polyether sulfone film material.
The air discharge duct of upper cover can be long strip type, also round.
Under cover and be provided with support film rib, rib side is medicinal liquid flow pass, after converging, from liquid outlet end, flows out.
Between liquid medicine filtering membrane and upper and lower cover, can be also to make its sealing at lower cover or upper and lower covers inner side increasing one elastic rubber fitting.
Air-filtering membrane should be the hydrophobic film that blocks water.
From exhaust liquid medicine filter, be used for substituting the liquid medicine filter on transfusion device.
This utility model is compared with conventional disposable infusion set clinically, on liquid medicine filter, cover and be provided with from air discharge duct and hole, and the air-filtering membrane of side heat seal therein, outer side bonds one tool plug air lock, when dropping funnel bottom hose enters after air, medical personnel can open plug in air lock, get rid of inner air tube, still can normal infusion during aerofluxus, after getting rid of, fills in beyond the Great Wall again air; This utility model can reduce medical personnel when routine is infused, because of after not changing in time medicine bottle air amount and entering in dropping funnel bottom hose, spend a lot of time the workload of carrying out aerofluxus, in the time of conveniently puncturing again, observe in time blood back, thereby it is safer to make to infuse, so both facilitated medical personnel easy to operate, save time, can avoid again medical tangle.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
the specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further detail.
In Fig. 1, this utility model by one from exhaust liquid medicine filter, comprise bottle plug puncture unit lower cover (1), upper cover (2), liquid medicine filtering membrane (3), air lock (4) and air-filtering membrane (5), air-filtering membrane (5) is heat sealing on the aerofluxus notch (2b) of upper cover (2), liquid medicine filtering membrane (3) be clipped in upper cover (2) and under (1) lid between, upper cover (2), lower cover (1) and liquid medicine filtering membrane (3) composition surface heat seal sealing, air lock (4) is bonded in row's mouth outside of upper cover (2), the inlet end (2a) of upper cover (2) is connected with infusion unit titrimeter bottom hose, the liquid outlet end (1a) of lower cover (1) is connected with transfusion device top hose, it is characterized in that: side bonds one tool plug air lock (4) outside the air vent of upper cover (2), when entering after air in transfusion device bottom hose, open plug in air lock (4), can get rid of the air entering in transfusion device bottom hose, fill in Nei Sai and can make again its sealing without leakage, interior plug can repeatedly be opened and fill in, liquid medicine filtering membrane (3) can be secondary filter film, can be also common filter membrane, and its membrane material can be plastics nucleopore thin film class film material or fibrous membrane material or polyether sulfone film material, the air discharge duct (2b) of upper cover (2) can be long strip type, also round, lower cover (1) is provided with support film rib (1b), and rib side is medicinal liquid flow pass, after converging, from liquid outlet end (1a), flows out, between liquid medicine filtering membrane (3) and upper and lower cover, can be to make its sealing at lower cover (1) or upper and lower covers inner side increasing one elastic rubber fitting, air-filtering membrane (5) should be the hydrophobic film that blocks water, from exhaust liquid medicine filter, be used for substituting the liquid medicine filter on transfusion device.
