Abstract
The utility model discloses an automatic propeller for vein infusion. An air storage tank is arranged, one end of the air storage tank is connected with an air scoop, and the other end is connected with a cylinder through an air supply conduit. A piston is arranged in the cylinder, a piston ring is fixed on the piston whose the other end is connected with a push rod on which a spring is sheathed, the other end of the push rod is fixed with a shielding head, and the front end of the cylinder is provided with an elastic clip for a needle cylinder. The manual work can be completely replaced by the utility model to process vein bolus, and uniform and stable bolus is ensured. The utility model has the advantages of convenient operation, safety and low cost. A medical care personnel's labor intensity is lightened, and work efficiency and nursing quality are enhanced.
Description
This utility model relates to a kind of medical instruments, belongs to a kind of automatic intravenous injection propeller.
Each hospital and medical institutions all have many patients need in time carry out the medicinal liquid intravenous injection, the injection liquid amount is that 10-50ml does not wait, inject required time between 5-20 minute, this work at present all is that medical personnel's hand syringes manpower is injected, because of the operating time long, firmly big and even, work difficulty and labor intensity are quite big, and is particularly more patient.Under the less situation of medical personnel, just can't in time inject more to patient.
The purpose of this utility model is that a kind of intravenous injection propeller that utilizes the gas pressure pushing syringe will be provided.
This utility model is realized in the following way: an accumulator is arranged, one end of accumulator is connecting suction nozzle, the other end connects cylinder by the conduit of supplying gas, one piston is housed in cylinder, fix a piston ring on the piston, the other end of the piston push rod of ining succession is with a spring on push rod, the other end of push rod is fixed a retaining head, at the front end of cylinder one elasticity syringe folder is arranged.
Below in conjunction with accompanying drawing this utility model is described.
Fig. 1 is a structural representation of the present utility model.
An accumulator ［ 1 ］ is arranged, one end of accumulator ［ 1 ］ connects a suction nozzle ［ 2 ］, suction nozzle ［ 2 ］ is gone up and is connected a three-way valve ［ 3 ］, one of three-way valve ［ 3 ］ leads to can directly connect oxygen tank, other one can connect an inflator ［ 4 ］ on logical, the other end of accumulator ［ 1 ］ connects cylinder ［ 9 ］ by the conduit of supplying gas ［ 5 ］, and air gauge ［ 6 ］ is housed on the conduit of supplying gas ［ 5 ］.Air inlet pressure regulator valve ［ 7 ］ and controlled pressure limiting valve ［ 8 ］, wherein air inlet pressure regulator valve ［ 7 ］ and controlled pressure limiting valve ［ 8 ］ both are interlockings.In cylinder ［ 9 ］ lining one piston ［ 10 ］ is housed, fix a piston ring ［ 11 ］ on the piston, the other end of the piston push rod ［ 12 ］ of ining succession, on push rod, be with a spring ［ 13 ］, the other end of push rod is fixed a retaining head ［ 14 ］, front end at cylinder ［ 9 ］ has elasticity syringe folder ［ 15 ］, and the syringe folder is to be used for fixing syringe ［ 16 ］.
When needs are injected, the syringe ［ 16 ］ that installs medicinal liquid earlier is fixed on the syringe folder ［ 15 ］, with the conventional puncture venous patient of the scalp acupuncture on the syringe and fix syringe needle, open air inlet pressure regulator valve ［ 7 ］ then, and regulate air inlet pressure regulator valve to suitable pressure and can inject automatically, its fltting speed can be controlled by controlled pressure limiting valve ［ 8 ］, inject finish after, take out scalp acupuncture, put gas control valve ［ 7 ］ into, open controlled pressure limiting valve ［ 8 ］, discharge the gas in the cylinder, push rod is got back to initial position automatically under the spring force effect, the gases at high pressure in the accumulator can be by manually squeezing into or inputing to certain air pressure by external source of the gas.
This utility model is to utilize inflator or source of the gas to import gases at high pressure in accumulator, gases at high pressure in the accumulator enter cylinder in the propeller by conduit, piston in the cylinder and push rod are pushed ahead under the gas pressure effect, finish action of injection with pushing syringe, air pressure in the cylinder is controlled by the air inlet pressure regulator valve, air gauge has shown the pressure size, and controlled pressure limiting valve can be regulated injection speed.Can replace artificial injector fully, simple in structure, easy to use, safe and reliable, do not need other energy, pollution-free and noise, cost is also lower, has not only reduced medical personnel's labor intensity, improved work efficiency greatly, the more important thing is and improved medical and nursing quality,, guaranteed the even of the speed of injecting for patient has striven for treatment time.Stable, be not subjected to artificial influence yet.
