The specific embodiment
With reference to explanation at length below the accurate light proofing infusion apparatus work of a kind of automatic vent of 5 pairs of this utility model of Figure of description 1 to accompanying drawing.
The accurate light proofing infusion apparatus of a kind of automatic vent of this utility model; Its structure comprises tube for transfusion 5, perforator 1, dropping funnel 4, flow regulator 6 and transfusion needle 8; Described perforator 1 and transfusion needle 8 are separately positioned on the two ends of tube for transfusion 5; Described dropping funnel 4 is separately positioned on the tube for transfusion 5 with flow regulator 6, and described tube for transfusion 5 is respectively double-decker with dropping funnel 4, and described tube for transfusion 5 comprises internal layer tube for transfusion 10 and outer tube for transfusion 9; Described dropping funnel 4 comprises internal layer dropping funnel 12 and outer dropping funnel 11; Described internal layer tube for transfusion 10 is respectively transparent medical grade plastics with internal layer dropping funnel 12 and processes, and described outer tube for transfusion 9 is respectively the lucifuge material with outer dropping funnel 44 and processes, and the top of the tube for transfusion 5 of described dropping funnel 4 bottoms extend in the dropping funnel 4; At least have a gas-liquid channel 13 on the described tube wall that extend into the inner tube for transfusion 5 of dropping funnel 4; Described gas-liquid channel 13 is communicated with the inner chamber of tube for transfusion 5, fixes through adapter sleeve 14 between described dropping funnel 4 bottoms and the tube for transfusion 5, and the tube for transfusion 5 of described flow regulator 6 bottoms is provided with accurate filter 15.
The described top shape that stretches into the tube for transfusion 5 in the dropping funnel 4 is to be extended and run through the semi-closed configuration of top sidewall to the top by gas-liquid channel 13 formed notch on the tube wall of tube for transfusion 5.When such configuration gets into gas-liquid channel 13 at medicinal liquid; For the air that is built in tube for transfusion 5 inner chambers provides the passage that escapes; Help medicinal liquid to be full of the inner chamber of tube for transfusion 5 as early as possible; Make tube for transfusion 5 tops can prevent that hydraulic shock from can effectively eliminate the air that is built in the tube for transfusion 5 again, avoid causing risk.
Described tube for transfusion 5 extend into the length of dropping funnel 4 inside more than or equal to 1/2 dropping funnel, 4 inner chamber height, and the bottom of described gas-liquid channel 13 is higher than dropping funnel 4 inner chamber bottoms.
The pore size filter of described accurate filter 15 is 0.2um-5um.To the microgranule more than the 5um in the medicine and macromole rejection rate greater than 98%.Can reduce the stimulation of medicine, reduce injury and reduction expense, alleviate medical personnel's labor intensity, guarantee safe and orderly the carrying out of infusion process patient to blood vessel.
Described accurate filter 15 is provided with automatic vent hole 17.Can avoid the problem of transfusion device exhaust problem.
Be provided with filter membrane 16 between described automatic vent hole 17 and the accurate filter 15, described filter membrane 16 is a poly (ether sulfone) film.Filter membrane 16 can only make gas pass through, and can not pass through liquid.
Described perforator 1 is provided with perforator medicated cap 2, and described transfusion needle 8 is provided with pin medicated cap 7.Avoided extraneous pollution of bringing for perforator 1 and transfusion needle 8.
Tube for transfusion 5 between described perforator 1 and the dropping funnel 4 is provided with clip 3.When needs stop to infuse, can directly tube for transfusion 5 be clamped and get final product with clip 3.
Medicinal liquid gets into dropping funnel 4 under action of gravity, can flow directly into the intracavity bottom of dropping funnel 4, because tube for transfusion 5 extend in the dropping funnel 4; Extend on the tube wall of the inner tube for transfusion 5 of dropping funnel 4 and have a gas-liquid channel 13 at least, and because the cause of liquid phase and solid phase surface molecule tension force objective reality, medicinal liquid can't get into immediately; And be blocked in the dropping funnel 4; Under the stopping of the tube for transfusion 5 that stretches into dropping funnel 4 inner chambers, medicinal liquid can be accumulated and in dropping funnel 4, raise liquid level gradually, and in the process that liquid level is elevated; The liquid extruding that unnecessary air has then been got in the dropping funnel 4, and the gas-liquid channel on tube for transfusion 5 13 is discharged by tube for transfusion 5; And when medicinal liquid was accumulated to about 1/2 dropping funnel, 4 inner chamber height, himself gravity overcame that surface molecular is tensile to be stopped, and got into gas-liquid channel 13, came downwards to the completion aerofluxus through tube for transfusion 5, realized need not human intervention, can self-bleeding performance.
The bottom of the gas-liquid channel 13 on the tube for transfusion 5 is higher than dropping funnel 4 inner chamber bottoms; Its raised area is airtight; So medicinal liquid is when getting into dropping funnel 4, this airtight part can relax and eliminate medicinal liquid and impact and potential energy down, makes it can not impact turbulent flow entering tube for transfusion 5 and the gas-liquid mixed of generation because of medicinal liquid; Make above-mentioned medicinal liquid not have other external force factors when accumulating and disturb, be able to smooth completion.
All adopt transparent medical grade plastics to process with the position internal layer tube for transfusion 10 that medicinal liquid directly contacts with internal layer dropping funnel 12; Outer tube for transfusion 9 is respectively the lucifuge material with outer dropping funnel 11 and processes; Can avoid of the influence of lucifuge additive, can reach the lucifuge effect in safe ready ground again, directly not contact with medicinal liquid to infusion process; Avoid causing unnecessary damages, significantly improve the transfusion work efficiency and strengthen the infusion treatment effect to the patient.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
