Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figures 1 to 6, the double medium filtration Anti-bubble automatic liquid-stopping multifunctional transfusion system that the present invention proposes, comprise tube for transfusion 1, perforator 2, dropping funnel 3, flow regulator 4, female Luer 5 and transfusion needle 6, tube for transfusion 1 is also provided with an Anti-bubble Double-filtering device, this Anti-bubble Double-filtering device comprises protecgulum 7, bonnet 8 and Anti-bubble part 9.
Protecgulum 7 inside has a circular medicine and crosses admission chamber 71, and this medicine is crossed admission chamber 71 and is divided into two parts by the filter membrane installation base 72 being horizontally installed on middle part, and top is divided into discharge chamber 73, and bottom is divided into heavy sap cavity 74.
The middle part of filter membrane installation base 72 is provided with a breach 75 that discharge chamber 73 is connected with heavy sap cavity 74, discharge chamber 73 bottom surface is provided with an air discharge duct 76, the bottom of air discharge duct is provided with steam vent 77, an emptying the air film 78 and face seal of this air discharge duct is fitted, the upper end of discharge chamber 73 is also connected with the intake tunnel 10 communicated, and intake tunnel 10 lower end is provided with the inclined plane 79 preventing medicinal liquid from producing bubble.
Bonnet 8 has circular medicine and crosses out sap cavity 81, and the rear portion of bonnet is provided with the exhalant canal 11 crossed out sap cavity 81 with medicine and be connected, exhalant canal 11 extend into medicine and crosses out certain altitude in sap cavity 81, medicine crosses out in sap cavity 81 and is also provided with ring shoulder 82, and this ring shoulder is provided with a sealing fine filtering of fitting and stops liquid film 83; .
Rounded and the coupling of Anti-bubble part 9 snaps in medicine and crosses in admission chamber 71, be fixed between the top of this Anti-bubble part and filter membrane installation base 72 liquid medicine filtering membrane 91, and the top of Anti-bubble part is provided with the Anti-bubble that multiple tracks vertically arranges crosses tank 92, the bottom of Anti-bubble part is provided with the arc boss 93 that coupling snaps in heavy sap cavity 74, and the groove width that Anti-bubble crosses tank is 0.5-0.7mm.
When infusing, medicinal liquid, first from intake tunnel 10 access to plant, arrives medicine and crosses admission chamber 71, first fall in heavy sap cavity, overflowing in discharge chamber, in the process that liquid level rises, by steam vent and air-discharging membrane interaction, is exhausted process.Intake tunnel 10 lower end is provided with inclined plane 79, this makes it possible to allow medicinal liquid enter into medicine cross in admission chamber 71 through being buffered in of inclined plane 79, prevents bubble from producing.
Meanwhile, raise along with liquid level, medicinal liquid is through liquid medicine filtering membrane, sap cavity 81 crossed out by the medicine that Anti-bubble through Anti-bubble part crosses tank arrival bonnet, along with the lasting liquid level of transfusion slowly goes up, overflow in exhalant canal 11 when increasing to certain height, discharge from exhalant canal 11.
Wherein, in medicinal liquid impurity stop by liquid medicine filtering membrane and cannot pass through, Impurity deposition is in heavy sap cavity, and the width of employing is that the Anti-bubble of 0.5-0.7mm is crossed tank and can be stopped the bubble that external diameter is greater than this width, bubble cannot be passed through, accomplishes Anti-bubble.
Cross out in sap cavity 81 at medicine, the height of exhalant canal 11 is enough high, medicinal liquid needs to overflow in pipe discharges, such impurity retains precipitation medicine and crosses out bottom sap cavity 81, when transfusion will at the end of, liquid level in shell cannot continue to overflow and enters into exhalant canal 11, it is secondary filter film that the fine filtering adopted stops liquid film, during this film chance water, fenestra opens, medicinal liquid can pass through, and when medicinal liquid departs from film body, fenestra is closed, and then blocks air is passed through, and then stopping infusion, accomplish automatic liquid-stopping, counterflow-preventing, ensure transfusion stabilization safety, stopped transfusion, prevent " blood back " phenomenon to produce.
Above-described embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
