Abstract
The utility model relates to chemical filtering equipment as a mating device for intravenous infusion or intramuscular injection, providing a chemicals filter which is composed of an upper housing (1), a bottom housing (4), a fluid inlet (6) and a fluid outlet (5). The utility model is characterized in that a hydrophobic air filtering film (2) and a hydrophilic chemical filtering film (3) are included. The utility model, with the advantages of wide application range, easy operation, sound filtering performance, safety and reliability, is mainly applied to filter 2mum-5mum insoluble particles in chemicals in case of infusion under gravity, infusion with presser or injection filtering; Meanwhile, air generated during the infusion will be exhausted.
Description
Technical field
This utility model relates to a kind of medical filtration device of usefulness supporting when medical treatment is clinical carries out venous transfusion or intramuscular injection medicinal liquid for the patient.
Background technology
Current, venous transfusion and intramuscular injection are still the most quick, the valid approach of clinical treating disease, but because infusion solutions is particles contained more, add that the contained insoluble substance of medicinal liquid is quick to this, effectively treatment means brings some sorry, long-term, the harm of hiding that to be transfusion particle bring health safety this, this is extensively confirmed by current medical science.Along with the raising of people's living substance, spiritual life level, people pay attention to the health and safety of life more, recognize that gradually transfusion particle endangers human body.Because the minimum blood capillary of adult is about 6 μ m~8 μ m, the then thinner 2 μ m~3 μ m that are about of child, in case big microgranule enters human body with transfusion, circulate at body, finally cause angiemphraxis, can cause a series of diseases, some be significantly, outbreak in a short time, more secular, hide.And clinical use mostly can only filtering 20 μ m microgranule, the factor that can filtering 2 μ m~5 μ m microgranules be confined to technology and cost that really comes into operation is very few.
Continuous development along with the clinical transfusion technology, pressure fluid delivery apparatus disposable infusion set has appearred, this product can be realized the low discharge transfusion, and infusion flow is carried out precision control, and its requirement to liquid medicine filter is higher: can bear the lasting 15min of 200KPa fluid pressure and not leak.And can only bearing 50KPa fluid pressure 20s, present liquid medicine filter do not leak.
Usually have air to produce in clinical transfusion process herb liquid, on the wall of the bubble that has attached to infusion tube, what have then enters human body with medicinal liquid, and big bubble carries out human body through being circulated to pulmonary, can cause air embolism, causes patient's death by suffocation.Therefore the bubble of infusing seriously jeopardizes patient's life security, and the liquid medicine filter with degassing function of clinical real use at present has only this utility model.
Summary of the invention
This utility model technical issues that need to address provide a kind of liquid medicine filter, to overcome the above-mentioned defective that prior art exists.
The said liquid medicine filter of this utility model comprises upper casing, drain pan, hydrophobic air filter membrane, hydrophilic liquid medicine filtering membrane, inlet and liquid outlet;
The bottom face of said upper casing all round is provided with projection along upper casing, and an end of projection is provided with the discharge orifice, and upper casing is provided with steam vent.
The upper surface of said drain pan all round is provided with the bead that matches with projection along drain pan, and a side of drain pan is provided with the feed liquor runner, and the outlet of feed liquor runner is arranged on the inboard of bead, and the inlet of feed liquor runner is arranged on the sidepiece of drain pan; The opposite side of drain pan is provided with the fluid runner, and the outlet of fluid runner is arranged on the sidepiece of drain pan, and the inlet of fluid runner is arranged on the inboard of bead, and said inlet is connected with the inlet of feed liquor runner, and liquid outlet is connected with the outlet of fluid runner;
Upper casing is fixedlyed connected with drain pan is compound, and said hydrophilic liquid medicine filtering membrane is arranged between upper casing and the drain pan, covers on the inlet of the outlet of feed liquor runner and fluid runner;
Said hydrophobic air filter membrane covers on the steam vent, is sap cavity between hydrophilic liquid medicine filtering membrane and the upper casing.
Medicinal liquid enters sap cavity from inlet by the discharge orifice during use, as being arranged in the medicinal liquid, air can discharge through steam vent by the hydrophobic air filter membrane, when infusion pressure is no more than 200KPa, medicinal liquid can not flow out from steam vent, by the hydrophilic liquid medicine filtering membrane, medicinal liquid flows out from liquid outlet behind hydrophilic medical filtration membrane filtration then.Filtered liquid medicine is aseptic, particles contained conformance with standard requirement, the usefulness for infusion that can be safe.
This utility model can overcome three big problems of clinical transfusion, but the air bubble that the particulate matter of 2 μ m~5 μ m, discharge produce in infusion process in the effective filter medicinal liquid, has high resistance to pressure (bearing the lasting 15min of 200KPa fluid pressure does not leak), but gravity transfusion or cooperation pressure fluid delivery apparatus are infused, and also can adopt the usefulness of injection filtration.Its cost is low, easy to operate, safe, effectiveness is good, adopts ultrasonic technology, can realize automated machine production.Reach the filtration to particulate matter harmful in the medicinal liquid, be used for discharging the air that produces in infusion process, the flow infusion also can cooperate the pressure fluid delivery apparatus to use greatly, realizes low discharge, and infusion flow is carried out precision control.
