Abstract
The utility model relates to a controllable propeller used for intravenous injection, which is an appliance used for medical intravenous injection and transfusion. A syringe is pushed by gravity with no need of human power and electric power. The utility model has the advantages of safety, easy maintenance and flexible and convenient use, reducing the work intensity and the workload of medical staff. The utility model can be used for intravenous injection and transfusion.
Description
The controlled propeller of this utility model intravenous injection gravity is a kind of utensil that is used for medical intravenous injection and transfusion.
Intravenous dose is often many, and the propulsive active force of hands is bigger, and the time is long, is the relatively work of hard work to numerous medical workers.Existing " intravenous injection electronic auto-control propeller " uses in some medical institutions.The problem that occurs from " intravenous injection electronic auto-control propeller " self characteristics and use has following shortcoming: the one, and do not have power supply not use, use the aneroid battery expense again than higher.The 2nd, electrical equipment is out of order easily, bad maintenance.The 3rd, flow to use inconveniently, syringe is desktop, needs suitable put place and power supply during use.
This utility model is to design according to the needs of medical work with at the shortcoming that " vein electronic auto-control propeller " exists.It is a kind of without electric power, without manual feed that the purpose of this utility model is to provide, reliably injecting propeller easily.
Fig. 1: the controlled propeller structure figure of intravenous injection gravity
The number in the figure explanation:
1, syringe needle; 2, tube for transfusion; 3, chassis; 4, cross over pipe; 5, flow speed control valve; 6, fluid box; 7, main body; 8, supporting roller; 9, syringe; 10, forward block; 11, pull rope; 12, hang bar; 13, spacing collar; 14, fixed screw; 15, gravity wheel; 16, traction wheel; 17, frame pipe; 18, gravity rope; 19, piston.
This utility model is provided by following examples and accompanying drawing:
Syringe (9) crouches and is put in the placing trough of main body (7), after forward block (10) is placed on the plunger of syringe (9), unclamp fixed screw (14), the piston (19) of hanging bar (12) and being associated in below it falls along frame pipe (17), driving gravity wheel (15) by gravity rope (18) rotates, with gravity wheel (15) concentric in parallel be that the traction wheel (16) of one also rotates thereupon, also done straight-line displacement around the pull rope of also putting on traction wheel (16) (11) by drive, just past reach of plunger of pushing syringe (9) of fixed forward block (10) is finished action of injection with medicinal liquid by tube for transfusion (2) and entry needle (1) on it.Frame pipe (17) is fixed on the chassis (3), and under the pipe inner carrier speed governing liquid being housed has cross over pipe (4) and flow speed control valve (5) in the bottom, communicates with fluid box (6), and flow speed control valve (5) plays the control injection speed, and spacing collar (13) plays the control injection volume.
Advantage of the present utility model:
(1) do not need electricity consumption, use the influence that is not subjected to short of electricity, power failure, also without battery, the capable of reducing using expense.
, reliably, be easy to maintenance (2) relatively safely.
(3) intravenous injection propelling and transfusion can be dual-purpose.
(4) mobile use is more convenient.
Claims (4)
1, a kind of controlled propeller of medical intravenous injection gravity that is used for is by hanging bar (12), piston (19), frame pipe (17), gravity rope (18), gravity wheel (15), traction wheel (16), pull rope (11), forward block (10), traction supporting roller (8), main body (7), chassis (3), cross over pipe (4), fluid box (6), spacing collar (13) is formed, its technical characterictic is: with the gravity of hanging bar (12) and piston (19) by gravity rope (18) drive gravity wheel (15) and with gravity wheel (15) concentric in parallel be traction wheel (16) rotation of one, be wound with pull rope (11) between traction wheel (16) and the supporting roller (8), be fixed with forward block (10) on the pull rope (11), above the leading portion of main body (7) placing trough of laying syringe (9) is arranged, frame pipe (17) upper end is equipped with gravity wheel (15) is installed, traction wheel (16), main body (7) lower end of supporting roller (8) is fixed on the chassis (3), and there is cross over pipe (4) frame pipe (17) lower end, flow speed control valve (5) and fluid box (6) UNICOM.
2, its technical characterictic of the utensil of intravenous injection according to claim 1 and transfusion is: with the concentric traction wheel that joins together of gravity wheel (15) (16) two both sides that are distributed in gravity wheel (15) are arranged.
3, its technical characterictic of intravenous injection according to claim 1 and infusion set is: supporting roller (8) has two skies to be enclosed within on the axis of main body (7) front end both sides, and is corresponding with traction wheel (16).
4, its technical characterictic of the utensil of intravenous injection according to claim 1 and transfusion is: the pull rope (11) on traction wheel (16) and supporting roller is two its equal in length, every all is that point schedules in traction wheel (16) groove, and circulation is on traction wheel (16), supporting roller (8).
