Description
Technical field
The present invention relates to technical field of medical instruments, and in particular to a kind of medical infusion device.
Background technology
Medical infusion bottle be for patient infusion fashionable dress the bottle of the liquid of medical configuration in defeated human body.Transfusion device is to use
In venous transfusion by aseptic process, set up the common disposable medical treatment consumptive materials of passage between vein and liquid.One
As by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, dropping funnel, bottle plug puncture unit, air inlet pipe, air mistake
Filter connection composition.Under atmospheric pressure effect, the infusion tube that liquid runs down is thinner in infusion bottle flows into dropping funnel, when dropping funnel water
When column pressure is more than vein pressure, the liquid runs down flexible pipe in bottle flows into vein.
The sterilization term of validity of medical worker's preoperation inspection disposable transfusion device and it is packaged with without gas leakage and other exceptions, takes
Go out transfusion device, cone joint part (bottle plug puncture unit) is inserted into infusion bottle, infusion bottle is hung on transfusion pole, be vented to liquid
Woven hose lower end is flow to, adjuster is fastened, then vein is needled into the vein for disinfecting, after fixing, untie tourniquet, adjusted
Commutating speed.
There is problems with existing transfusion device：
First, liquid flow velocity most at first in woven hose is very fast, and as liquid flows out, the fluid column in bottle slightly drops
Low, overhead gas volume slightly becomes big, and pressure is slightly reduced so that the total pressure of bottle mouth position is slightly smaller than external atmosphere pressure, outer big
Air pressure is strong just to supplement air from air inlet pipe press-in bottle, the pressure of bottle mouth position is remained essentially in an atmospheric pressure, makes medicine
Liquid energy is at the uniform velocity stably dripped, and is not changed again with gradually decreasing for bottle Chinese medicine liquid, but interior i.e. flow velocity of incipient short time is also
Before stabilization, the pressure of bottle mouth position can be slightly larger than an atmospheric pressure, so easily dripping very in a period of time for most starting
Hurry up, easily bring discomfort to patient body.
Second, when transfusion speed is very fast, the liquid level short time in infusion bottle changes greatly, because air inlet pipe is arranged on bottle stopper
On puncture outfit, the inlet channel of air inlet pipe is very thin, and air just timely cannot enter supplement in infusion bottle by air inlet pipe, from
And cause to change during the pressure at infusion bottle mouth very greatly, therefore the phenomenon dripped that liquid cannot at the uniform velocity be stablized occurs.
When how to ensure transfusion, no matter transfusion speed is fast, or slowly, it is one that what liquid can at the uniform velocity be stablized drips
The technical problem of very worth research.
The content of the invention
The technical problem to be solved in the present invention：Within a period of time for starting, liquid easily drips very existing transfusion device
Hurry up, it is impossible to which at the uniform velocity stable drips, and easily brings discomfort to patient body；In infusion process, liquid sediment easily hinders sometimes
The path of air inflow openings is filled in, along with air inlet pipe is arranged on bottle plug puncture unit, the inlet channel of air inlet pipe is very thin in itself,
Be easily caused air just timely cannot enter supplement in infusion bottle by air inlet pipe, so that during pressure at infusion bottle mouth
Change is very big, therefore the phenomenon dripped that liquid cannot at the uniform velocity be stablized occurs.
In order to solve the above technical problems, the technical solution adopted by the present invention：Medical infusion device, including cuboid holds
Device, rectangle baffle plate, the first cuboid cavernous body, the second cuboid cavernous body, infusion port, liquid inlet and air inlet；
Described rectangle baffle plate is located inside cuboid container, following table of the rectangle baffle plate parallel to cuboid container
Face；
The seamless connection in former and later two faces of described rectangle baffle plate Yu cuboid container；
Described rectangle baffle plate keeps certain spacing with the face of left and right two of cuboid container；
Described rectangle baffle plate will not be deformed upon because of the pressure of top liquid；
The first described cuboid cavernous body is identical with the second cuboid sponge shape；
Described the first cuboid cavernous body, the second cuboid cavernous body, rectangle baffle plate and cuboid lower surface one
Rise and form a closed cavity；
The first described cuboid cavernous body can ensure that liquid penetrates into another side by the one side of itself；
The second described cuboid cavernous body can ensure that liquid penetrates into another side by the one side of itself；
Described liquid inlet is arranged at the upper surface of described cuboid container, and rubber is provided with liquid inlet
Plug；
Described air inlet is arranged at the upper surface of described cuboid container, and air cleaner is provided with air inlet；
Described infusion port is arranged at the lower surface of described cuboid container, and rubber stopper is provided with infusion port.
Further more preferred technical scheme, air inlet is located at the center of cuboid container upper surface.
Further more preferred technical scheme, infusion port is located at the center of cuboid container lower surface.
Further more preferred technical scheme, it is described the first cuboid cavernous body, the second cuboid cavernous body, rectangular
Shape baffle plate and cuboid lower surface form volume of the volume size for closed cavity equivalent to cuboid container together
The 1/50. of size
Compared with prior art, the beneficial effects of the invention are as follows：
First, a kind of medical infusion device proposed by the present invention just can be at the uniform velocity steady in the very short time liquid that transfusion most starts
Fixed drips, and will not bring discomfort to patient body；Second, even if transfusion speed is very fast, air remains able to add in time
What infusion bottle Chinese medicine liquid still can at the uniform velocity be stablized drips.
