Abstract
The automatically flowing pollution-free infusion bottle includes bottle body, bottle cap and bottle stop, and features the inside bag with mouth connected the bottle mouth and the liquefied gas inlet on the bottle body and connected to a miniature liquefied gas tank. The present invention has inside bag pressurized with the liquefied gas, and this avoid the contamination of ambient air to the medicine liquid and eliminates the infusion frame for convenient infusion. The present invention is especially suitable for field first aid.
Description
Technical field
The present invention relates to a kind of infusion bottle, particularly a kind of can pollution-free transfusion and the unrestricted infusion bottle in transfusion position.
Background technology
Traditional infusion model belongs to the gravity transfusion, needs the gas-liquid exchange could guarantee transfusion, and surrounding air will cause the pollution of bottle inner liquid medicine.Must rely on drip stand during transfusion, the patient is inconvenient to move freely, and can't implement the first aid transfusion especially in the open air.In order to reach pollution-free operation, disclose the infusion bottle of capsula interna frame mode on the existing patent documentation, its structure is to set up a soft capsula interna in normal infusion bottle, capsula interna is total to mouth with bottleneck and fixedlys connected, splendid attire medicinal liquid in the capsula interna, for medicinal liquid is input in the human body, still need suspension bracket, and passage is set on bottle communicates with atmosphere.The hole of inflating that the band check valve is set on bottle that also has, injection pressure gas between bottle and capsula interna, ensureing infuses carries out, though this mode has changed the mode of gravity transfusion, makes things convenient for patient movement to a certain extent, but carrying out along with transfusion, pressure will reduce gradually, cause medicinal liquid flow velocity inequality, even can not flow out, influenced it and promoted the use of, and implementation cost height (needing to be equipped with proprietary pump-up device).
Summary of the invention
Technical problem to be solved by this invention provides a kind of gravity flow non-contamination transfusion bottle, not only can reach pollution-free operation, and transfusion place, transfusion position be not subjected to the restriction of drip stand, and is simple in structure, easy to use, constant pressure, medicinal liquid flow speed stability.
Gravity flow non-contamination transfusion bottle of the present invention comprises bottle, bottle cap, bottle stopper, it is characterized in that being provided with in the bottle capsula interna, and the oral area of capsula interna and bottleneck mouth altogether are connected and fixed, and liquefied gas inlet is set on the bottle, and import department connects a miniature liquid gas storage tank.
The present invention sets up capsula interna in common bottle, adopt nontoxic flexible material to be made, and the major technique characteristics are to utilize liquefied gas to act on the outer wall of capsula interna, make the medicinal liquid in the capsula interna keep constant pressure, flow speed stability.
The connected mode of liquid gas storage tank and bottle can realize according to multiple enforceable mode, liquefied gas inlet place as bottle is provided with a connection piece, liquid gas storage tank tank body and connector are connected in one (can pass through thread connecting mode), and liquefied gas inlet docks with the outlet of liquid gas storage tank.The liquefied gas of splendid attire is entered between bottle and the capsula interna by the bottle import in the liquid gas storage tank, and liquid moment gasification produces pressure, and the pressure size and reaches balance rapidly on the liquefaction point of liquefied gas.Along with the carrying out of transfusion, the medicinal liquid in the capsula interna reduces gradually, and the cavity volume between bottle and the capsula interna enlarges gradually, and the liquefied gas in the liquid gas storage tank is constantly mended, and keeps constant pressure.Therefore the volume of liquid gas storage tank is advisable to finish transfusion just, or excessive a little.
Liquefied gas can adopt other enforceable products such as liquefaction normal butane, liquefied ammonia, can keep 0.5～2 kilogram/cm at normal temperatures
2Pressure.
During transfusion, after adding medicine, begin to install liquid gas storage tank, implement transfusion to capsula interna.
Infusion bottle be placed on if staff can and the position all can, can not need transfusion stand, but dropper preferably to be kept normal vertical mode, dropper can be fixed on the bottle.Keep flat the position if dropper is in, preferably make the liquid that has 2/3 volume in the dropper, prevent the air admission blood vessel in the dropper.So for safety, prevent dropper generation out of plumb phenomenon in the infusion process, when beginning to infuse, just make the liquid that has 2/3 volume in the dropper.
Advantage of the present invention:
Owing to adopt capsula interna and produce ambient pressure by liquefied gas, avoided the pollution of surrounding air to medicinal liquid, guarantee aseptic transfusion, and do not need transfusion stand during transfusion, can make things convenient for patient movement, make the patient finish infusion process more easily.The present invention especially provides convenience for field emergency.Simple in structure, easy to operate, implementation cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 bottle cap, 2 bottle stoppers, 3 bottlenecks, 4 bottles, 5 capsula internas, 6 liquefied gas inlets, 7 liquid gas storage tanks, 8 liquid gas storage tanks export 9 connectors
The specific embodiment
As Fig. 1, form common infusion bottle by bottle 4, bottle cap 1, bottle stopper 2, bottleneck 3, in bottle 4, place capsula interna 5, capsula interna is the plastic bag shape, its oral area and the bottle oral area heat seal made from rigid plastics together, total same bottleneck 3.Offer liquefied gas inlet 6 on bottle, be added with tapped connector 9 at import 6 places, the tank wall of liquid gas storage tank 7 has external screw thread and connector links together by engage thread, the liquefied gas inlet 6 of the outlet 8 of liquid gas storage tank on the bottle.Liquid gas storage tank 7 has 3～4 milliliters volume, in fill with liquefaction normal butane or liquefied ammonia, bottle is 500 milliliters.
During use, open bottle cap 1, preparating liquid is injected in the capsula interna 5 by syringe, installs transfusion device, and liquid gas storage tank 7 is installed then, comes into effect transfusion.After liquid gas storage tank is mounted, liquid in it enters the cavity between bottle and the capsula interna immediately, and the moment gasification produces pressure, impel the medicinal liquid in the capsula interna in human body, to import, along with medicinal liquid constantly reduces, the intravital liquefied gas of liquid gas storage tank jar constantly mends cavity, keeps constant pressure to act on the capsula interna outer wall.
Claims (2)
1, gravity flow non-contamination transfusion bottle comprises bottle, bottle cap, bottle stopper, it is characterized in that being provided with in the bottle capsula interna, and the oral area of capsula interna and bottleneck mouth altogether are connected and fixed, and liquefied gas inlet is set on the bottle, and import department connects a miniature liquid gas storage tank.
2, infusion bottle according to claim 1 is characterized in that the liquefied gas inlet place of described bottle is provided with a connection piece, and liquid gas storage tank tank body and connector are connected in one, and liquefied gas inlet docks with the outlet of liquid gas storage tank.
