Abstract
The utility model discloses a hydraulic intravenous syringe which comprises a machine frame, an injection needle tube arranged on the machine frame and a miniature electric pump fixed on the machine frame, wherein an oil tank and a control valve are arranged on the machine frame. The miniature electric pump is connected with an inner cavity of the oil tank through an oil suction tube. An oil outlet tube of the miniature electric pump is connected with the control valve. A piston type oil cylinder is arranged above the machine frame. The oil cylinder is connected with the control valve through a catheter. The front end of a piston of the oil cylinder is provided with a pushing rod which is tightly contacted with a push-and-pull seat of a needle pin of the injection needle tube. The utility model has the advantages of simple structure and easy use. The utility model can assist nursing personnel to automatically carry out patients' intravenous injection, and can be applied to clinic, and the nurses' labor intensity can be lightened. The utility model is an ideal intravenous injection appliance.
Description
Technical field this utility model belongs to nursing injector technology field, relates in particular to a kind of hydraulic pressure intravenous injector.
Background technology is well-known, and intravenous drug is an internal medicine nursing for treating method commonly used, be widely adopted clinical, and the medicinal liquid of injection 20ml, manual operations approximately needs 7-10 minute, makes the nurse produce feeling of fatigue easily, has increased nursing work load.
The summary of the invention the purpose of this utility model provide a kind of easy to use, can assist the nursing staff automatically patient to be carried out intravenous hydraulic pressure intravenous injector, to overcome the deficiencies in the prior art.
To achieve these goals, this utility model hydraulic pressure intravenous injector, comprise frame and be located at the injection needle on the frame and be fixed on mini electric pump on the frame, its main points are that frame is provided with fuel tank and control valve, mini electric pump links to each other with the inner chamber of fuel tank through fuel sucking pipe, the oil exit pipe of mini electric pump links to each other with control valve, and the top of frame is provided with ram cylinder, and oil cylinder links to each other with control valve through conduit; The front end of oil cylinder piston is provided with pushing ram, and pushing ram closely contacts with the pintle push-and-pull seat of injection needle.
This utility model is simple in structure, and is easy to use, can assist the nursing staff automatically patient to be carried out intravenous injection, is applied to the clinical nurse's of alleviating labor intensity, is a kind of more satisfactory arteries and veins instrument used for injection.
Description of drawings Fig. 1 is this utility model structural representation.
The specific embodiment with reference to the accompanying drawings, this utility model frame 2 is " U " type structure, its bottom is fixed with mini electric pump 5, one side of frame 2 is provided with fuel tank 6 and control valve 7, frame 2 downsides are equipped with fixing control frame 4, frame 2 tops are fixed with a ram cylinder 9 through gripper shoe, also be fixed with the on and off switch 8 of a control micromotor 5 on the support 2, the intracavity inter-connection of the fuel sucking pipe of micromotor 5 and fuel tank 6, micromotor 5 oil exit pipes link to each other with control valve 7, control valve 7 communicates with oil cylinder 9 through pipeline, and the reciprocating motion of ram cylinder 9 inner carriers can drive pushing ram 3 move left and right that are attached thereto.
When this utility model uses, at first select suitable fixed-site on the sick bed limit fixed mount 4, after then intravenous injection needle tube 1 being sequenced gas, place on the frame 2 at pushing ram 3 front end positions, the pintle push-and-pull seat of injection needle 1 is against on the pushing ram 3 of oil cylinder 9 front ends, to patient's scalp acupuncture that punctured, scalp acupuncture is connected on the nipple of intravenous injection needle tube 1 by tube for transfusion, closed on and off switch 8, mini electric pump 5 extracts liquid through oil exit pipe evenly in fuel tank 6, control valve 7 is fuel feeding in oil cylinder 9, the piston of oil cylinder 9 promotes pushing ram 3 and travels forward evenly, thereby the medicinal liquid in the quiet injection needle 1 is advanced in the vein blood vessel.
