Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As Figure 1-4, this safe transfusion system comprises protective sleeve 1, bottle plug puncture unit 2, soft dropping funnel 5, hard dropping funnel 6, transfusion catheter 11, flow regulator 12, threeway 13, liquid injecting piece 14, two-way screw joint 15 and intravenous needle 16, bottle plug puncture unit 2 is sleeved on soft dropping funnel 5 through dropping funnel lid 2a, hard dropping funnel 6 is installed in the bottom of soft dropping funnel 5, the bottom of hard dropping funnel 6 connects transfusion catheter 11 one end, the other end of transfusion catheter 11 is through flow regulator 12 connecting tee 13, the dosing mouth of threeway 13 is arranged rubber cap 13a, the other end of threeway 13 to be connected liquid injecting piece 14 successively by transfusion catheter, two-way screw joint 15 and intravenous needle 16, protective sleeve 1 is sleeved on bottle plug puncture unit 2, overall formation safe transfusion system, it is characterized in that: bottle plug puncture unit 2 installs air-filtering membrane 4 in integrated injection molding dropping funnel lid 2a and airport 2b, airport 2b and is sealed by air filtration cap 3, hard dropping funnel 6 inner bottom surface installs liquid medicine filter 10 and is fixed by liquid medicine filter lid 9, floating plug 7 is contained in hard dropping funnel 6, and the concave surface 7a that latex cap 8 is embedded in floating plug is interior relative with the infusion port 9a of liquid medicine filter lid.
As shown in Fig. 1,3,4, the external diameter of described floating plug 7 is more smaller than hard dropping funnel 6 internal diameter, and the outside of floating plug is gear-like sidewall, and the top of floating plug is ball-type buffering convex surface, and the bottom of floating plug is concave surface 7a.
As shown in Fig. 1,3,4, described latex cap 8 is the latex ring that one side is provided with Emulsoid-film 8a, and latex cap 8 entirety plug is in the concave surface 7a of floating plug, and Emulsoid-film 8a is just to infusion port 9a.
As shown in Fig. 1,3,4, concave surface 7a inwall and latex cap 8 joint of floating plug have air channel 7b, and the size of air channel 7b ensures that medicinal liquid cannot enter floating plug cavity under normal infusion state.
As shown in Figure 1, arrange in soft dropping funnel 5 and only rise bank 5a, floating plug 7 is active in and only rises between bank 5a and infusion port 9a.
Wherein, soft dropping funnel and hard dropping funnel combination after dropping funnel capacity be respectively: 6cc, 8cc, 10cc, 12cc, 14cc.
As shown in Figure 2, another embodiment of the present utility model: flow regulator 12 is replaced as delicate flow actuator 12A, and intravenous needle 16 is replaced as scalp acupuncture 16A.
When transfusion operation starts, first take off protective sleeve 1, bottle plug puncture unit 2 is inserted in infusion vessel bottle stopper, again the air filtration cap 3 of air inlet 2b is opened, medicinal liquid automatically enters in soft dropping funnel 5 under the effect of atmospheric pressure and self gravitation, the top ball-type being first dropped in floating plug 7 cushions on convex surface and is flowed in hard dropping funnel 6 by dispersion drain through the space of gear-like sidewall, along with the accumulation gradually of medicinal liquid, comparatively medicinal liquid is light for the density of the plastic material that floating plug 7 adopts due to it, rise under the buoyancy of liquid, Emulsoid-film 8a leaves binding face and automatically opens infusion port 9a, medicinal liquid flows through liquid medicine filter 10 and enters in transfusion long duct 11 again, finally flow out from intravenous needle 16 needle tubing endoporus, air in each parts of automatic eliminating, when medicinal liquid is nearly totally lost, floating plug 7 is along with liquid level decline, when contacting to Emulsoid-film 8a with infusion port 9a, under atmospheric pressure and floating plug 7 gravity pressure, Emulsoid-film 8a just tightly blocks infusion port 9a, infusion pipeline under making air not enter into infusion port 9a, thus prevent air from entering patient's vein.
Above-mentioned only for the technical solution of the utility model is described, and be not limitation of the utility model, those skilled in the art, when not departing from the spirit and scope of utility model, can also make a variety of changes and modification, all equivalent technical schemes also belong to category of the present utility model.
