Abstract
A kind of disposable infusion set is used for the liquid medicine filter of hospital clinical transfusion, transfusion device, adopts non-polar polymeric material, foam-like structure.Profile is block cylinder.Sintering, foam process, compression molding.Through experiment confirm, technical specification is superior, meets GB GB8368-87 regulation fully, becomes to can be used for clinical, good disposable infusion set fully.
Description
The present invention is a kind of disposable infusion set, is medical appliance.
Disposable infusion set is the medical apparatus of only using as disposable infusion in the hospital clinical.According to China standard GB 8368-87 regulation, it is made up of cork perforator (1), medicine liquid channel (2), band air filter and stopper air inlet (3), dropper (4), dropping funnel (5), liquid medicine filter (6), conduit (7), liquid injecting piece (8).GB 2,23 regulation transfusion devices should no abnormal toxicity.Person's non-toxic reaction tackled medicinal liquid and is subjected to liquid by the material of GB 2,3 regulation transfusion devices.The dropping funnel of GB 2,7 regulation transfusion devices is interior or terminal should to be equipped with the liquid medicine filter that can filter the insoluble particle of 10-25 μ m, and its filterability should be not less than 80%.GB 2,13 regulation transfusion device inner chambers feed 20kpa air pressure and continue 15 hours, and leakage must not be arranged.These regulations are to the material of transfusion device, and the performance of connecting portion bond state and liquid medicine filter has all been done strict restriction.
The requirement of 2,7 pairs of medicine liquid device filterabilities of GB is strict, because filterability is bad, can endanger patient, malpractice occurs.The material of filter, technology, structure just become the object of technical research, bring in constant renewal in, and bring benefit to the mankind.
The liquid medicine filter of external report-be hard sheet by the dense knot crystal structure, this thin slice is in the lower bottom part of dropping funnel (5), plays filtration.Because the cylindrical and the dropping funnel inwall of hard sheet are always gapped, be difficult to guarantee to filter precision.Another kind then is a film type, has the filter opening that is similar to mesh structure, and filter opening is crossed detailed rules and regulations and is difficult to satisfy in the GB about the requirement of flow velocity, excessively then is difficult to guarantee filterability again.
Task of the present invention is to improve material, structure, shape and the technology of liquid medicine filter (6).A kind of once use transfusion device that meets the GB regulation is provided, and simple in structure, easy to use, cost is low.
Technical scheme of the present invention is that liquid medicine filter (6) is block cylinder, and its material is a non-polar polymeric material, adopts sintering, foam process, compression molding.Non-polar polymeric material through sintering, foam process is foam-like structure, has bigger elasticity.Elastic performance makes the border that joins between medical filtration filter (6) and dropping funnel (5) inwall keep compressing shape, can get rid of along dropping funnel (5) tube wall and leak the filter phenomenon.Bubble in the balloon-shaped structure, not of uniform size.Because it intersects in length and breadth and constitutes nonlinear type and filter at many levels, guarantees to filter precision.In the experiment confirm filter liquor, can not find the above insoluble medicine grain of 10 μ m, meet and be better than GB 2,7 regulations fully.
Because the block cylinder bodily form that technical scheme of the present invention proposes, foaming structure is a raw material with the non-polar polymeric material, sintering, foam process, compression molding have guaranteed the technical quality requirement of liquid medicine filter, meet the GB regulation, simple in structure, easy to use, finished the invention task.
Introduce the present invention in detail below in conjunction with accompanying drawing;
Fig. 1 is the structure chart of disposable infusion set.
Fig. 2 is the structure chart of dropping funnel.
Fig. 3 is liquid medicine filter structure and outline drawing.
Cork perforator (1) (seeing figure (1)) is one and inserts in the liquid holding container during use similar in appearance to the aciculiform object that medicinal liquid splashes into dropping funnel (5) along medicine liquid channel (2) through dropper (4).Filter tailing edge conduit (7) through liquid medicine filter (6) and be injected into human body through liquid injecting piece (8).Band air filter and stopper QI KOU (3) are the draught heads that needs for dropping liquid.
Dropping funnel (5) is a kind of transparent tube, can be glass tubing, also can be nontoxic, tasteless lucite pipe.(Fig. 2 a) also can be connected forms dropping funnel (5) with following dropping funnel (Fig. 2 c) by last dropping funnel (Fig. 2 b).When dropping funnel (5) adopts nontoxic, tasteless plastics, during the method that is connected of two dropping funnels, can adopt hot melt adhesive technology up and down, be tightly connected, constitute whole.Before the adhesive seal, earlier liquid medicine filter (6) is put into down in the dropping funnel.
Liquid medicine filter (6) is by non-polar polymeric material, makes block cylindrical shape.(see figure 3).The main component of this non-polar polymeric material can be a polyethylene, can be polypropylene also, adds they self additive.Through sintering, foam process, compression molding.Non-polar polymeric material through foam process is foam-like structure, has bigger elasticity, cylinder type liquid medicine filter (6) after the compression molding, its body diameter can be a bit larger tham the interior warp of pipe of dropping funnel (5), the elasticity of foam-like structure makes medicine liquid device (6) and the interior posthumous title of dropping funnel (5) waterside 3 value get over the faint-hearted ┮ of crushed rices coffin thorn Nyctereutes procyonoides third constellations flavor and penalizes) gap between inwall and liquid medicine filter (6) side surface spills, cause Lou filter phenomenon, guarantee filterability.Bubble in liquid medicine filter (6) balloon-shaped structure, not of uniform size, intersect in length and breadth, it is poroid to be linked to be crooked capillary, constitutes nonlinear type and filters at many levels, improves to filter precision.
Liquid medicine filter can be that (Fig. 3 also can be that upper surface is that circular pit (Fig. 3 b) is arranged a) to full circle cylinder shape.Pit can be conical (Fig. 3 d), and the effect of pit is mainly to filter by pit after drop splashes into dropper (5), guarantees to filter precision.The bottom of cylinder type liquid medicine filter can be designed to stepped ramp type (Fig. 3 c), and it plays a part to cooperate positioning and fixing with following dropper, and this dropper bottom has the step (9) of protrusion at present.The external form of liquid medicine filter also can be that upper surface has pit, lower bottom part that the block cylinder of step combination is arranged.
Dropping funnel (5) is transparent tube bodies nontoxic, tasteless plastics, and nontoxic, tasteless plastics can be used non-toxic polyvinyl chloride.For improving rigidity, the dropping funnel outer surface has reinforcement.It is withstand voltage that hot melt adhesive technology guarantees that sealing links the back, meets GB.Can design positioning and fixing boss step (9) in the following dropper, match, guarantee that the location is pressed fixing and raising filters precision with bottom liquid medicine filter with the level (6).Following dropper can not have positioning step yet.
Fig. 3 e is the partial enlarged drawing of liquid medicine filter (6) material structure of foam-like structure, and bubble is not of uniform size, different as seen from the figure, axially sees along cylindrical, constitutes the multi-level tortuous filter road of non-linear shape.
The other pieces of disposable infusion set of the present invention are all made with non-toxic material, use the disposable infusion set that technical solution of the present invention is made, experiment confirm meets the GB requirement fully, technical indicator is comprehensively superior, particularly leach and can not find the above insoluble particle of 0.05 μ m in the liquid, can be used for clinical fully. Its volume is little, and is in light weight, and cost is low, easy to use.
