The specific embodiment
Shown in Fig. 1-13, automatically stopped filter infusion apparatus from exhaust, comprise Y word pipe 4 and liquid medicine filter 11 that the two ends with drop tube 8 bond together by flexible pipe 16 respectively, the other end of Y word pipe 4 by two flexible pipes 16 connect respectively have Intake Cover I1-1 handle air inlet bottle pin I2-1 is arranged and has an Intake Cover II1-2 handle air inlet bottle pin II2-2 arranged, sealing card I3-1 is stuck in the outside of the flexible pipe 16 that connects between handle air inlet bottle pin I2-1 and the Y word pipe 4, sealing card II3-2 is stuck in the outside of the flexible pipe 16 that connects between handle air inlet bottle pin II2-2 and the Y word pipe 4, the other end of liquid medicine filter 11 is mutually bonding with screwed union 12, chimeric screwed union sheath 14 on the screwed union 12, water ends frame 10 and is socketed in and is used on the flexible pipe 16 that is connected between drop tube 8 and the liquid medicine filter 11 regulating, the control flow, be provided with two membranes in the liquid medicine filter side by side, be respectively air filtration film 11-1 and liquid medicine filtering membrane 11-2.Also comprise two micropore level regulators 9, air filtration film 13, two micropore level regulators 9 are circular knob base 9-6, rectangle liquid level post 9-2 and fan-shaped liquid level base for post platform 9-1 three in one molding structure, on circular knob base 9-6, be respectively equipped with semicircle groove 9-7 with the bottom surface, round recessed 9-8, outer half dog points of circular knob base 9-6 and bottom surface are provided with the inclined-plane 9-6-1 that a circle inwardly shrinks, be provided with rectangle liquid level post 9-2 on the fan-shaped liquid level base for post platform 9-1 on two micropore level regulators 9, the high 16.5mm of rectangle liquid level post 9-2, fan-shaped liquid level base for post platform 9-1 accounts for regulator base 1/4th areas, rectangle liquid level post 9-2 is a hollow structure, a circular cylindrical cavity 9-13 is established at its center, on the face of rectangle liquid level post 9-2 one end, be provided with rectangular recess 9-3, upper end in rectangular recess 9-3 is provided with the liquid level capital hole 9-4 of diameter 0.8mm, upper surface at rectangle liquid level post 9-2 is provided with open recess 9-5, on the periphery of the circular knob base of two micropore level regulators 9, be provided with rectangle blind hole 9-10, be provided with an opening 9-12 above the rectangle blind hole 9-10, the width of opening 9-12 is 0.6mm, on the inwall of rectangle blind hole 9-10, be provided with circular hole 9-10-1, the diameter 1.0mm of circular hole 9-10-1, in two micropore level regulator 9 bottom surface round recessed 9-8, be respectively equipped with hole 9-11 under the liquid level base for post platform, liquid level post bottom outlet 9-9, hole 9-11 communicates with circular hole 9-10-1 under the liquid level base for post platform, and liquid level post bottom outlet 9-9 communicates with liquid level capital hole 9-4 by circular cylindrical cavity 9-13.Screwed union sheath 14 is made of the tubular body of integrated two different-diameters, is provided with a circle platform 14-1 two intravital connecting parts of tubulose, on the circle platform 14-1 of liquid medicine filtering membrane 13 hot welds in screwed union sheath 14 pipes.Two micropore level regulators 9 are entrenched in drop tube 8 inner close fitting drop tube 8 bottoms and inwalls, and the equal driving fit in contact site is seamless.
This principle of device is, liquid level capital hole 9-4 communicates with liquid level post bottom outlet 9-9 by circular cylindrical cavity 9-13 in two micropore level regulators 9, be used for fluid injection and discharge a tube 8 interior air in earlier stage to keep an internal gas pressure balance, rectangular recess 9-3 purpose on the rectangle liquid level post 9-2 is liquid level capital hole 9-4 is surrounded, open recess 9-5 is used to dredge the medicinal liquid that splashes into tube, the effect of these two grooves is that the medicinal liquid of avoiding falling is blocked liquid level capital hole 9-4, the opening 9-12 that is positioned on the blind hole 9-10 communicates with hole 9-11 under the liquid level base for post platform, this path is the medicinal liquid path, be used for unimpeded liquid, its split shed 9-12 width 0.6mm, circular hole 9-10-1 diameter on the rectangle blind hole 9-10 inwall is 1.0mm, and this opening and circular hole are very narrow not dirty immediately when utilizing liquid tension to make liquid arrive herein at first.Two films placed side by side in the liquid medicine filter 11 are respectively air filtration film 11-1 and liquid medicine filtering membrane 11-2,11-1 gas-permeable, liquid-impermeable of air filtration film, play the effect of discharging bubble, the only saturating liquid of liquid medicine filtering membrane 11-2 is airtight, the effect of playing filtering liquid medicine and ending liquid.Weldering one air filtration film 13 in screwed union sheath 14 1 ends, this film gas-permeable, liquid-impermeable plays the effect that liquid is discharged gas in the transfusion device when dirty and liquid terminated in this sheath after medicinal liquid is full of transfusion device.
When this transfusion device uses, medical personnel at first will have handle air inlet bottle pin 2-1 and have handle air inlet bottle pin 2-2 to insert liquid bag or liquid bottle respectively, or one of them there is handle air inlet bottle pin 2-1, there is handle air inlet bottle pin 2-2 to insert liquid bag or liquid bottle, liquid begins dirty, originally flow into and dripped tube at 8 o'clock, because the tension force effect of liquid, medicinal liquid terminates in opening 9-12, discharge gas by liquid level post 9-2 simultaneously and keep tube 8 an internal gas pressure balance, liquid level rises in dripping tube 8, when liquid level rises to liquid level capital hole 9-4 and it is blocked, owing to can't discharge gas again, dripping tube 8 internal gas pressures increases, pressure surpasses the liquid tension at opening 9-12 place, force medicinal liquid from opening 9-12 by circular hole 9-10-1 9-11 outflow in hole under the liquid level base for post platform, then medicinal liquid passes through liquid medicine filter 11, flexible pipe 16, screwed union 12 arrives the air filtration film 13 that is positioned on the screwed union sheath 14, the function of this film gas-permeable, liquid-impermeable stops at herein medicinal liquid, and topping up is finished.Whole process need not medical personnel's nurse, medical personnel only need handle air inlet bottle pin 2-1 will be arranged and have handle air inlet bottle pin 2-2 to insert liquid bag or liquid bottle respectively, or one of them there is handle air inlet bottle pin 2-1, has handle air inlet bottle pin 2-2 to insert liquid bag or liquid bottle, can leave, when to be used screwed union sheath 14 is pulled up, connect corresponding scalp acupuncture, implement transfusion and get final product.After all medicinal liquid is totally lost, medicinal liquid drops to liquid medicine filter 11 places, because the liquid medicine filtering membrane 11-2 in the liquid medicine filter 11 has the only saturating air-locked function of liquid, liquid will stop at this film and no longer descend, gas behind the replacing liquid bag in the transfusion device pipeline can be discharged by air filtration film 11-1, this device has been avoided having alleviated the transfusion risk of sufferer greatly because of the careless and inadvertent or untimely sufferer blood back that causes of replacing liquid bag.
