Another object of the present utility model is to provide a kind of transfusion device with above-mentioned dropping funnel, and this transfusion device can effectively reduce nurse's workload while using, and the transfusion that alleviates patient is painful.
To achieve these goals, the technical solution of employing is this utility model:
A transfusion device, what comprise that above-described embodiment provides has an only dropping funnel of liquid and filtering function
The beneficial effects of the utility model:
There is the dropping funnel and the transfusion device that stop liquid and filtering function, simple in structure, easy to use, time saving and energy saving, saving medicinal liquid.This dropping funnel the function of liquid medicine filter and only liquid function combine together, by liquid filter membrane only, complete simultaneously and filter and the function of liquid only, simplified manufacturing process, automated production in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the exploded view with the dropping funnel that stops liquid and filtering function.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model embodiment is described in detail:
Embodiment 1
In conjunction with Fig. 1, there is the dropping funnel that stops liquid and filtering function, comprise superposed the first shell 2 and the second housing 7 that is positioned at bottom, the top of described second housing 7 has annular groove, insert in annular groove the bottom of the first shell 2, make the first shell 2 and second housing 7 peg graft to be integral and form dropping liquid district, the upper end of described the first shell 2 connects to splash into manages 1, and the lower end of second housing 7 connects delivery line 8.The inside of described second housing 7 is provided with only liquid filter membrane 3, and the inside of second housing 7 is provided with annular boss 4, and only liquid filter membrane 3 is fixed on annular boss 4.
Described only liquid filter membrane 3 is hydrophilic porous films, and aperture is between 2～5 microns.Described the first shell 2 is made by PVC material, splashes into pipe 1 and is made by ABS plastic or PVC material.
Described delivery line 8 stretches in second housing 7, and the top of delivery line 8 is connected with a plurality of water conservancy diversion gripper shoes 6, and water conservancy diversion gripper shoe 6 is erect radially and distributed.The upper end of described water conservancy diversion gripper shoe 6 is provided with supporting pad 5, and supporting pad 5 is supportting and stopping liquid filter membrane 3.The height of the delivery line 8 in described second housing 7 is lower than the height of water conservancy diversion gripper shoe 6.
The processing technology of dropping funnel, by the only liquid filter membrane of 16 mm dias, lie in a horizontal plane on annular boss, adopt the method for ratio-frequency welding or ultra-sonic welded to be fixed on annular boss stopping liquid filter membrane, afterwards upper Ketohexamethylene is dipped in in the lower end of the first shell, insert in the annular groove of second housing, the first shell and second housing bond together, and are loaded on other parts such as splashing into pipe, delivery line and can be made into a set of transfusion device.
Only liquid filter membrane is a kind of microporous membrane of Superhydrophilic, and because fenestra only has 2～5 microns, liquid has a filtering function through out-of-date; It is speckling with under the situation of water, and owing to having filled water in fenestra, now fenestra can not pass through air, and now only liquid filter membrane has the only function of liquid, can replace the transfusion device filter of GB8368 standard, reaches the object of dual-use material.
The object that water conservancy diversion gripper shoe and annular boss are set below liquid filter membrane is only:
To stopping liquid filter membrane, play a supportive role, reduce water conservancy diversion gripper shoe to stopping the area that stops of liquid filter membrane as far as possible, do not reduce porosity as far as possible, or reduce less porosity, do not reduce filter membrane by the total amount of liquid as far as possible.
Water conservancy diversion gripper shoe has the function of venting bubble, and principle is to utilize the principle of surface tension of liquid, first the liquid through stopping liquid filter membrane is entered to the bottom of second housing, makes air converge to central point along water conservancy diversion gripper shoe and extrudes dropping funnel.
In order to make full use of the only effective area of liquid filter membrane, prevent from when dropping funnel is infused, pushing the first shell aerofluxus, because bearing pressure in dropping funnel, be limited, if the pressure of extruding is too large, may cause only liquid filter membrane distortion, change the only aperture of liquid film, cause and can not stop liquid, or affect flow velocity and slow down.Therefore,, in order to protect only liquid filter membrane, below liquid filter membrane only, water conservancy diversion gripper shoe and annular boss are set.
The height of the delivery line in described second housing is less than 0.5 millimeter of the height of water conservancy diversion gripper shoe, and this is designed with and is beneficial to second housing aerofluxus, utilizes the surface tension of water, entering the only air of liquid filter membrane lower end, drains.
Product occupation mode:
Bleeding: when dropper is carried liquid to dropping funnel, by the outlet of the delivery line of dropping funnel upward, only liquid filter membrane does not contact medicinal liquid, and at this moment air will, by stopping liquid filter membrane, be discharged from delivery line.
Another kind method is the aerofluxus that makes progress of extruding the first shell, and bottle plug puncture unit is inserted after infusion bottle, pinches and presses the first shell, and Exhaust Gas, makes medicinal liquid enter dropping funnel, adjusts liquid level to needed height.
Medicinal liquid in infusion bottle flows to end, and the medicinal liquid in dropping funnel is when only liquid filter membrane is equal, and air contact is liquid filter membrane only, and only liquid filter membrane will stop air to enter.Only the transfusion of liquid filter membrane below will stop, and treats that nurse changes bottle.Deng changing after new bottle, at extruding the first shell, air-out, sucks dropping funnel by medicinal liquid, adjusts liquid level, drop amount, continuation transfusion.
Embodiment 2
In conjunction with Fig. 1, a kind of transfusion device, has the only dropping funnel of liquid and filtering function that has described in embodiment 1.
Certainly; above-mentioned explanation is not to restriction of the present utility model; this utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
