Description

A kind of intravenous transfusion device provided with elastic force type floating valve and filtering and purifying
Technical field
A kind of intravenous transfusion device is the utility model is related to, is specifically that one kind is provided with elastic force type floating valve and filtration, purification The bivalve intravenous transfusion device of device.
Background technology
Intravenous transfusion device is the visual plant of clinical treatment, and the treatment and rehabilitation to patient have played main effect, mesh The defects of preceding intravenous transfusion device used is due to structure and design, has the following disadvantages in Clinical practice, first, transfusion outpatient side During sleeping or transfusion limb elevation, the blood reflux phenomenon in infusion niidl is easily caused;Second, during transfusion, as run into infusion bottle Decoction drips light, when not changing infusion bottle in time, in dropper will air inlet or blood reflux, when change again infusion bottle continue it is defeated During liquid, the air in woven hose will enter in human vas, and the rehabilitation to human body adversely affects;Three be due to use Murphy's transfusion device drop kettle in be not provided with screen pack, before transfusion, by nurse in advance to adding medicine in transfusion bottle when, it is difficult Exempt to have in other drugs impurity or bacterium, cell entry infusion bottle, human body is inputted by transfusion device, also patient can be caused to hinder Evil.
The content of the invention
Therefore, people to provided with elastic force type floating valve and filtering and purifying intravenous transfusion device exist greatly it is expected and Demand.Up to now, it has not been found that on relevant report of the invention, the present inventor passes through development test repeatedly, finally The intravenous transfusion device provided with elastic force type floating valve and filtering and purifying successfully is developed, so as to complete the present invention.
The purpose of this utility model is just to provide a kind of resistant to blood provided with elastic force type floating valve and filtering and purifying and returned Intravenous transfusion device is flowed, to solve the problems, such as being backflowed without filter screen and blood flow for Murphy's transfusion device.
Scheme of the present utility model include drop kettle, buoyancy valve cylinder, buoyancy valve seat, bevel gear shape floating valve, drop keyholed back plate, Upper and lower woven hose, transfusion connector and scalp intravenous needle, it is structurally characterized in that described drop kettle for the transparent of a cylindrical, hollow Shell body, the outer upper end of shell body are provided with upper tubing, and the upper end of upper tubing is provided with puncture needle, be provided with drop kettle shell body with The buoyancy valve cylinder that buoyancy valve seat is connected, the interior upper end of buoyancy valve cylinder are provided with the drop keyholed back plate of observation transfusion drip speed speed, floating valve The upper middle part of cylinder is provided with buoyancy valve seat, and the middle part of buoyancy valve seat is provided with floating valve inlet opening, and the lower end of floating valve inlet opening is provided with Bevel gear shape floating valve, the upper end of gear-like floating valve are provided with spring, and spring upper end is fixed on buoyancy valve seat spring groove Interior upper end, the circumference on the outside of floating valve are provided with guide cylinder, and the circumference of guide cylinder is provided with fluid hole, the lower middle part of buoyancy valve cylinder Be provided with screen pack provided with cross base, in cross base, described guide cylinder, buoyancy valve seat, spring, cross base and Buoyancy valve cylinder is cast as one, and is combined into elastic force buoyant filter purification association, the elastic force buoyant filter purification association is fixed It is arranged in drop kettle, is fixed as one with drop kettle, the lower end for dripping kettle is provided with lower infusion tube, and the lower end of lower infusion tube is provided with transfusion and connected Joint, transfusion connector are sealed in the outer end of lower infusion tube, lower buoyancy valve rod, lower floating valve are provided with the pipeline for connector of infusing The lower end of post is provided with lower bevel gear shape floating valve, and the upper end of lower conical gear-like floating valve is provided with lower spring.Under described Buoyancy valve rod is cast as one with lower bevel gear shape floating valve, and the outside of lower buoyancy valve body is provided with lower guide cylinder, lower guide cylinder Circumference be provided with fluid hole, lower guide cylinder is used for liquid outflow and is oriented to and control elastic limit, plane on gear-like floating valve The lower infusion tube of upper end is intraoral to be provided with lower buoyancy valve seat, and upper end in buoyancy valve seat spring groove is fixed in lower spring upper end, under lead Bevel gear shape floating valve is set with spring and valve seat combination into down spring buoyancy control valve, down spring buoyancy control valve under to cylinder It is placed in transfusion connector, is closed with film, the inner side of lower transfusion connector is provided with sealing film provided with internal thread, bottom, close The lower end of sealing film is provided with standby scalp intravenous needle, and the upper end of scalp intravenous needle is provided with external screw thread.In use, open sealed thin Film, scalp intravenous needle threaded connection is arranged on to the inner of transfusion connector to infuse.
During transfusion, by the puncture needle insertion transfusion bottle of transfusion device upper end, the decoction in transfusion bottle is along upper tubing Into in drop kettle, in the presence of atmospheric pressure and liquid head pressure, liquid washes the gear-like floating valve of lower end in drop kettle open, to Lower to enter after strainer filtering purifies in lower infusion tube road, the liquid flowed downwardly into washes the lower cone in transfusion connector open again Gear-like floating valve, flowed into along scalp vein needle tract in the vein blood vessel of patient.Upper conical gear-like floating valve point simultaneously End props up overcentre above cross, to control elastic limit.When the decoction in transfusion bottle drips light, the circular cone in kettle is dripped Shape gear-like floating valve floats in the presence of spring retraction force blocks fluid hole, and liquid-transport pipe-line is closed, defeated under making Fluid in liquid pipe road stops flowing downward.While the lower bevel gear shape floating valve in connector of infusing returns in spring Floated in the presence of contracting power, upper plane blocks woven hose fluid hole upwards, and fluid hole is closed, and prevents blood from being returned to woven hose Stream, then can safety etc. next bottle of infusion vessel to be replaced continue to infuse.On described lower conical gear-like floating valve Plane and fluid hole are combined into new fluid control device, and during transfusion, decoction flows out the sky through floating valve upper end by fluid hole Between and gear grooved in space outflow, both can ensure that the smooth of transfusion, the anti-Hemostatic Oral Liquid of and can backflows.
This hair have it is simple in construction, it is ingenious in design, processing cost it is low, safe to use, positive effect.
It is described in further detail below in conjunction with the accompanying drawings.
