Description
Technical field
The present invention relates to fluid delivery apparatus, especially a kind of precisely fine tuning infusion apparatus.
Background technology
There is a dropper in the funnel of infusion apparatus, foundation of the number of drops of outflow as flow in dropper per minute, so
Infusion apparatus is also known as dropper, and international standard 20 drips=1ml.
Infant, urgent patient or some drugs need micro infusion at a slow speed, which drips 1ml drop numbers, but the number for 60
According to it is very slow be difficult to calculate, and 60 drop 1ml cannot meet the flow of common transfusion again, and have a flow set micro- currently on the market
Regulated fluid infusion device, flow-controllable are 5-270ml per hour, which is to hang the physiological saline of 100ml in infusion bottle to test
The scale of mark setting flow under specified conditions, but the viscosity of drug, species, many factors such as blood pressure of temperature and human body all can
The flow velocity of liquid is influenced, so the error of the infusion apparatus is very big.
The content of the invention
It is an object of the invention to provide one kind precisely to finely tune infusion apparatus, has easy to operate, fine tuning accuracy rate height, structure
The advantages of simple at low cost.
The technical proposal of the invention is realized in this way：
A kind of precisely fine tuning infusion, by bottle plug puncture unit, upper conduit, liquid stopping clamp, dropper, dropping funnel, downcomer, adjuster and filtering
Device is linked in sequence composition, and bottle plug puncture unit, upper conduit, liquid stopping clamp, dropper, dropping funnel, downcomer, adjuster and filter sequence connect
It is logical, there are 2 droppers in the dropping funnel, be big dropper and small dropper respectively, big dropper is set in outside small dropper, the lower end of small dropper
It is extended to from the lower nozzle of big dropper in dropping funnel, the upper orifice of small dropper upper end from big dropper is extended in upper conduit.
The upper catheter jacket is equipped with liquid stopping clamp.
The downcomer is connected with adjuster.
The adjuster is flow set micro actuator or wheel folder flow regulator.
The big dropper is made with small dropper of hard material.
Every 20 drop of drop of the big dropper is 1ml, and every 60 drop of drop of small dropper is 1ml.
Beneficial effects of the present invention are as follows：
1. flow is accurate, error is small, and the main purpose of trace regulation is to adjust amount of infusion, and the present invention controls stream by drop
Amount does not calculate flow with graduated volumetric, is influenced from factors such as the blood pressures of the viscosity of drug, species, temperature and human body.
2. easy to operate, according to clinical needs during fine tuning, the flow needed per hour is how many just adjust it is how much per minute
Drop during common transfusion, is then operated with the big dropper of 20 drop 1ml, when especial patient is infused, then grasped with small dropper 60 ± 3 drop for 1ml
Make.
3. it is simple and practical in structure, it is of low cost, there is great market popularization value and space.

Specific embodiment
As shown in Figure 1, the present invention by bottle plug puncture unit, upper conduit, liquid stopping clamp, dropper, dropping funnel, downcomer, adjuster and
Filter sequence connection composition, bottle plug puncture unit, upper conduit, liquid stopping clamp, dropper, dropping funnel, downcomer, adjuster and filter are suitable
Sequence connects, and has 2 droppers in the dropping funnel, is big dropper and small dropper respectively, big dropper is set in outside small dropper, small dropper
The lower nozzle of lower end from big dropper is extended in dropping funnel, and the upper orifice of small dropper upper end from big dropper is extended in upper conduit.
The upper catheter jacket is equipped with liquid stopping clamp, and the downcomer is connected with adjuster, and the adjuster sets for flow
Determine micro actuator or wheel folder flow regulator, the big dropper are made with small dropper of hard material, the big dropper
Every 20 drop of drop is 1ml, and every 60 drop of drop of small dropper is 1ml.
In the use of the present invention, as shown in Figures 2 and 3, common transfusion pattern opens liquid stopping clamp, big dropper and small dropper
It being connected simultaneously with upper conduit, small dropper and big dropper export drop simultaneously, at this point, the flow is every 20 drop 1ml, fine tuning infusion
When, liquid stopping clamp is closed, and only small dropper is connected with upper conduit, at this point, the flow is every 60 drop 1ml, example：Clinic needs to be every point
Clock 1ml liquids, then observation obtains drop number per minute as 60 ± 1 drops after adjuster is opened completely.
