Technical field
The invention discloses a kind of transfusion device accessory, being specially a kind of disposable transfusion device with dripping kettle assembly, belonging to technical field of medical instruments.
Background technology
Disposable transfusion device be a kind of be mainly used in venous transfusion through aseptic process, the common disposable medical treatment consumptive materials of setting up passage between vein and medicinal liquid.Generally connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle, bottle plug puncture unit, air inlet pipe air filter.Its operation principle is under atmospheric pressure effect, and the infusion tube that in bottle, liquid runs down is thinner flows into dropping funnel, and when dropping funnel water column pressure is greater than venous pressure, the liquid runs down flexible pipe in bottle flows into vein.
And drip a kettle and there are 1. guiding medicinal liquids enter, 2. store medicinal liquid, 3. observe medicinal liquid flow velocity, 4. observe medicine liquid level and the effect such as how much, the current kettle assembly that drips drips kettle main body for comprising, and drips the pot lid being provided with coupling suitable for reading of kettle, pot lid is provided with upper conduit, air filter and chemical feed pipe.The bottom of dripping kettle is dropping funnel, and the cental axial position of dropping funnel is provided with aerofluxus post.
The defect of this kettle assembly is:
1, extruding dropping funnel is needed to make medicinal liquid enter dropping funnel before using;
2, liquid level in uncontrollable dropping funnel, does not control the flow of infusing;
3, have bubble to enter during transfusion into the liquid, bubble enters human body with medicinal liquid and easily causes aeroembolism.
Summary of the invention
The object of the invention is to provide a kind of disposable transfusion device with dripping kettle assembly, to solve the problems referred to above of prior art.
Object of the present invention can be achieved through the following technical solutions.
Disposable transfusion device is with dripping a kettle assembly, and comprise and drip a kettle main body, drip that kettle main body is suitable for readingly provided with pot lid, end opening is provided with dropping funnel, described drips upper conduit kettle pot lid being arranged and connects infusion tube; Described dropping funnel is made up of connecting portion and dropping funnel portion, described connecting portion is socketed for mating with a kettle main body and binds, described dropping funnel portion is infundibulate, arranges a circle step in the junction of dropping funnel portion and connecting portion, the inwall of dropping funnel is provided be no less than three convex stupefied; Described is convex stupefied concordant with step upper surface, and is pressed with liquid medicine filtering membrane at step and convex stupefied patrix; The axis of dropping funnel is provided with an aerofluxus post.
The part of described aerofluxus post in dropping funnel is feed liquor post, and the part outside dropping funnel is the downcomer be connected with infusion tube; The sidewall of described feed liquor post is provided with and is no less than two vertical long and narrow lead channel.The width of lead channel is more than 35 decimillimeters.Described downcomer oral area inside edge place is chamfering.Transfusion catheter is that outside plug type connects.
Described step is provided with a circle boss, to facilitate bonding air-filtering membrane.The height of described boss is greater than 1mm.
The described pot lid dripping kettle assembly or sidewall are provided with the air filter that blocks water be in communication with the outside, and the air filter that blocks water is supporting seal cover.What block water air filter is column air vent dripping the part in kettle.
Described dripping on kettle pot lid is also provided with chemical feed pipe, to facilitate the dosing when dropping liquid.
The dropper mouth of described upper conduit and the distance of air vent are more than 1cm, so that observe.
Described air-filtering membrane is hydrophobicity CN-CA, and its aperture from top to bottom diameter reduces successively, and diameter is 2-10nm, and more preferred diameter is 3-8nm.
The disposable transfusion device designed by the present invention, with dripping kettle assembly, has following beneficial effect:
1, without the need to extruding dropping funnel, liquid rapid and natural flows into dropping funnel;
2, air vent can control the height of liquid level in dropping funnel, effectively can control infusion flow:
3, aerofluxus post can bubble effectively in drain, prevents bubble to enter human body.
