Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of safe transfusion system, include bottle plug puncture unit 1, dropping funnel 2, flow regulator 3, transfusion catheter 4, venoclysis needle 6, it is characterized in that, dropping funnel 2 is made up of dropping funnel body 8 and the dropping funnel lid 7 being positioned at dropping funnel body 8 top, dropping funnel 9, outer dropping funnel 10 two parts in dropping funnel body 8 points, dropping funnel chamber 14 in interior dropping funnel inwall 11 is combined with dropping funnel lid 7 and forms, top, interior dropping funnel chamber 14 is combined with steam vent 19, the dropping funnel lid 7 on top, interior dropping funnel chamber 14 is provided with dropping funnel feed tube 21, and interior dropping funnel liquid outlet 18 top of interior dropping funnel 9 bottom is provided with only liquid filter membrane 16; Outer dropping funnel inwall 13, dropping funnel lid 7 and interior dropping funnel outer wall 12 combine the outer dropping funnel chamber 15 of composition, and outer dropping funnel chamber 15 is combined with can the air inlet 22 of folding, and the dropping funnel liquid outlet 25 of bottom, outer dropping funnel chamber 15 is provided with automatic exhaust device 27.
Only liquid filter membrane 16 is fixed on the supporting surface 17 of interior dropping funnel 9 bottom.Steam vent 19 is provided with exhaust gas filter film 20, exhaust gas filter film 20 is fixed on dropping funnel lid 7.Air inlet 22 is arranged inlet air filtration film 23, inlet air filtration film 23 is fixed on dropping funnel lid 7.Inlet air filtration film 23 is outside equipped with gland 24, can open, close air inlet 22.The dropping funnel lid 7 on dropping funnel body 8 top is provided with liquid injection device 26.
As shown in Figure 2 and Figure 4; described automatic exhaust device 27 is made up of gas-liquid separation pipe 29 and protective cover 28; the top of gas-liquid separation pipe 29 is stretched in outer dropping funnel 10; the inside of bottom and dropping funnel liquid outlet 25 is adhesively fixed; dropping funnel 2 is stretched out in lower end; be connected with transfusion catheter 4, the top that protective cover 28 is arranged on gas-liquid separation pipe 29 is relative with interior dropping funnel liquid outlet 18.Protective cover 28 is umbrella or plane.One or more gas-liquid separation groove 30 is provided with in gas-liquid separation pipe 29.
As shown in Figure 1, transfusion catheter 4 end below flow regulator 3 is provided with precision liquid medicine filter 5.
In the embodiment of the present invention; at transfusion initial period; medicinal liquid flows into interior dropping funnel chamber by dropping funnel feed tube from dropping funnel lid; medicinal liquid flows into outer dropping funnel chamber after complete wetting stops liquid filter membrane and is full of interior dropping funnel chamber; the medicinal liquid dripped from interior dropping funnel chamber first drops in protective cover; protective cover reduces the potential energy of drop, makes drop finally can only slowly fall into outer dropping funnel chamber along the peripheral clearance of protective cover.The medicinal liquid flowing into outer dropping funnel chamber can raise gradually, and because gas-liquid separation pipe is distributed with gas-liquid separation groove vertically, because its capillary effect, in the absence of external forces, can only pass through air, medicinal liquid cannot enter.Therefore when medicinal liquid falls from protective cover, form the liquid level of certain altitude gradually around gas-liquid separation pipe, along with the rising of liquid level, the air in outer dropping funnel chamber is also concentrated from the gas-liquid separation groove of gas-liquid separation pipe and is automatically discharged.When the pressure that liquid level is elevated to medicinal liquid generation is greater than the surface tension of gas-liquid separation groove, medicinal liquid starts the inside entering gas-liquid separation pipe from gas-liquid separation groove, thus enter in the transfusion catheter of dropping funnel bottom, because the medicinal liquid in outer dropping funnel chamber is abundant, the medicinal liquid now entering transfusion catheter is continuous print.Like this, in whole infusion process, in catheter of transfusion system, there will not be the medicinal liquid of entrapped air, thus be mixed into bubble in medicinal liquid when avoiding transfusion, not needing " aerofluxus bubble " operation of transfusion, alleviating the labor intensity of medical personnel, having saved the nursing time.
When the medicinal liquid in infusion bottle completes infusion and after the only liquid filter membrane automatic liquid-stopping of interior dropping funnel bottom, as needs of patients change infusion bottle proceed infusion time, can this transfusion device directly be inserted in new infusion bottle, the air in the air in dropping funnel feed tube and interior dropping funnel chamber can be discharged to the external world by steam vent at this moment in interior dropping funnel chamber automatically, along with the discharge gradually of air in transfusion device, newly change infusion bottle herb liquid and also dropping funnel chamber in lasting inflow is realized the continuous transfusion function after automatic liquid-stopping.
After whole infusion process completes, due to the existence of automatic liquid-stopping function, medicinal liquid under dropping funnel and dropping funnel in tube for transfusion cannot continue the intravenous being infused into patient, now, the air inlet being in normally off can be opened by medical personnel, such outside air enters into outer dropping funnel chamber after being filtered by air inlet, thus the medicinal liquid in dropping funnel and its lower end transfusion catheter can be continued to be infused into patient's intravenous, realize the complete infusion of medicinal liquid truly, avoid and lessen the curative effect because of liquid waste.
Infusion pipeline end in the preferred embodiment of the present invention below flow regulator is provided with precision liquid medicine filter, precision liquid medicine filter is provided with automatic vent window, (minute bubbles are adsorbed as transfusion ambient temperature effect causes in pipeline) when bubble fails all to eliminate in some cases, by exhausting window, bubble in transfusion catheter is discharged, avoid bubble etc. to enter human body, improve the safety of transfusion device further.
