The front side and the back side of the shell are provided with an upper guide oblique groove and a lower guide flat groove. The intersection point between the upper guide oblique groove and the lower guide oblique groove is provided with a warning line or a switch mechanism. The center part of the regulating wheel is provided with a shaft, the both ends of the shaft are respectively extended out of two end surfaces of the regulating wheel, and are respectively arranged in the guide grooves. The regulating wheel can be moved in the longitudinal direction of the wheel groove along the guide groove. The flow regulator for infusion has the advantages of simple structure, easy manufacture, convenient operation, and high successful operation rate and efficiency, can relieve the pain of patients, etc.
Description
This utility model relates to a kind of transfusion flow regulator, belongs to a kind of flow regulator that is applicable to that disposable infusion is used.
Venous patient when transfusion, judge whether syringe needle enters whether to see behind the inserting needle blood back in the vein blood vessel.But when situations such as the patient who runs into severe loss of blood, circulatory failure, Chronic consumptions and infant, adiposis patient, because the angioplerosis degree is little, pressure is on the low side, influences blood back behind the inserting needle, thereby makes troubles to operation, even causes erroneous judgement.The flow regulator that existing disposable transfusion device is provided with is equipped with regulating wheel in the race between its housing front and back sides.Only be provided with the guiding skewed slot on the housing front and back sides, when regulating wheel vertically moved in race along the guiding skewed slot, regulating wheel changed the pressure size of transfusion sebific duct thereupon, to regulate the transfusion of infusion flow and switch.And to above-mentioned special circumstances, then powerless.For this reason, medical personnel need ask the another one people to assist rib in transfusion often, with infuse sebific duct and clutching of hands opisthotonos, make the transfusion sebific duct from the syringe needle to the invagination be in closed state.After treating that needle slope enters skin fully, unclamp invagination, again syringe needle is further inserted blood vessel, whether observe blood back then, whether insert blood vessel to judge syringe needle.Whole operation is extremely inconvenient, also wastes time and energy, and efficient is low.The not situation of blood back also appears simultaneously easily.Cause operation failure, bring misery to patient.
The purpose of this utility model provides simple, the easy to operate transfusion flow regulator of a kind of new structure, the success rate and the operating efficiency of venipuncture when infusing to improve.
For achieving the above object, the technical solution of the utility model is:
This transfusion is made up of housing, regulating wheel with flow regulator.Housing is made up of bottom surface and former and later two sides.Be provided with race, race between the two sides, front and back for vertical.Regulating wheel is contained in this race.Be shaped on gathering sill respectively on the two sides before and after the housing.The center of regulating wheel is shaped on axle, the both ends of the surface that regulating wheel is stretched out at the two ends of axle respectively.And be contained in the gathering sill respectively.Regulating wheel can be along vertically moving in the race of this gathering sill between the housing front and back sides.Being produced on before and after the housing gathering sill on the two sides is risen as high as the banks by top skewed slot and bottom and combines.The bottom surface of top skewed slot and housing is in a certain angle and tilt, and the bottom is risen as high as the banks parallel with the bottom surface of housing.Two grooves intersect in the lower end of skewed slot.
Be shaped on caution line or switching mechanism on the housing of the skewed slot and the intersection of rising as high as the banks.Switching mechanism can be the concavity groove of two groove intersections, and the bottom surface of concavity groove is a little less than the bottom surface of rising as high as the banks, and the upper side of concavity groove is protruding downwards.
The utlity model has following advantage and effect.
1, simple in structure, be easy to make and promote.
2. easy and simple to handle, a people just can easily finish whole operation.When transfusion, before syringe needle does not thrust skin, only regulating wheel need be moved on to and rise as high as the banks bottom, promptly near syringe needle one end, tube for transfusion is in closed condition.After needle slope thrusts skin fully, on move regulating wheel to lead skewed slot and guiding rise as high as the banks caution line or the switching mechanism place or a certain position of its downside of intersection.Sebific duct infuse this moment owing to pressing of regulating wheel still be in closed condition, and the pipe inner liquid medicine does not flow to syringe needle.But because the variation of regulating wheel position causes this section transfusion sebific duct internal volume to increase, liquid in pipe pressure reduces, and helps blood back.After syringe needle thrusts blood vessel, can observe easily whether blood back is to determine whether operation is successful.Whole operation a people easily finish.
3. operating efficiency and success rate height were both time saving and energy saving, can alleviate patient's misery again.
Below in conjunction with drawings and Examples this utility model is described in further details.

Fig. 4: the structural representation (the local amplification) that is shaped on concavity groove switching mechanism
Flow regulator is used in this transfusion, and by housing (1), regulating wheel (4) is formed.Housing (1) is made up of former and later two sides (3) and bottom surface (8): former and later two sides are shaped on race between (3), and race is for vertical: regulating wheel (4) is contained in the race.Be shaped on gathering sill respectively on housing (1) front and back sides, gathering sill by top skewed slot (2) and bottom rise as high as the banks (6) form.Top skewed slot (2) is in a certain angle with the bottom surface (8) of housing (1) and tilt: the bottom rise as high as the banks (6) parallel with the bottom surface (8) of housing (1).Regulating wheel (4) center is shaped on axle (5), and two end faces of regulating wheel (4) are stretched out at axle (5) two ends respectively, and the two axial ends of axle (5) is contained in respectively in the gathering sill on housing (1) front and back sides (3).Regulating wheel (4) can vertically move in race along gathering sill.Skewed slot (2) intersects in the lower end of skewed slot (2) with rise as high as the banks (6).When this transfusion was contained on the tube for transfusion with flow regulator, the transfusion sebific duct was contained between the bottom surface (8) of regulating wheel (4) and housing (1), and regulating wheel (4) is pressed on the sebific duct.When regulating wheel (4) move to rise as high as the banks (6) bottom the time (the most nearby) apart from syringe needle, the transfusion sebific duct is in and is conditioned wheel (4) and presses and closed condition.This moment, available needle slope inserted skin.Move regulating wheel (4) then to caution line or a certain position of caution line downside.Regulating wheel (4) presses the transfusion sebific duct always in above-mentioned moving process, make medicinal liquid not flow to syringe needle, and the transfusion sebific duct still is in closed condition.But the change of regulating wheel (4) position makes that this section transfusion sebific duct pipe internal volume from regulating wheel (4) to syringe needle increases, and pipe inner liquid medicine pressure reduces, and is easy to blood back.This moment syringe needle is thrust blood vessel and observe the blood back situation.When the syringe needle blood back, show syringe needle intravasation, can infuse, can obtain the suitable speed of dripping this moment by regulating regulating wheel (4) at the position change regulating wheel (4) of upper guide down fold (2) pressure to the transfusion sebific duct.
Guiding skewed slot (2) can also be made a concavity groove switching mechanism (10) with guiding (6) intersection of rising as high as the banks.The bottom surface of concavity groove switching mechanism (10) is a little less than the bottom surface (9) of rise as high as the banks (6), and the upper side of concavity groove (10) is protruding downwards.
