Abstract
A safety plug gravity infusion device belongs to the infusion device class, mainly comprising an infusion device and an infusion tube. The infusion device is a transparent cylinder jet molded of polyvinyl chloride plastics. The upper part of the infusion device is connected with an upper infusion tube, and the upper cover of the infusion device is firmly glued with the lower body of the infusion device through plastic adhesive. A float is arranged in the lower body of the infusion device, the upper cover of the float is firmly glued with the lower body of the float through plastic adhesive. The periphery of the upper cover of the float is provided with supporting poles to make the float keep a vertical up-down movement. A safety plug can accurately block the lower orifice of a fluid accumulating groove to stop an infusion. Due to the effects of the gravity and the suction force, the safety plug rubber is transformed to block the lower orifice of the fluid accumulating groove. The utility model has the advantages that the device has simple structure, convenient use, is scientific, reasonable and novel, improves the problem that watching over is required during an infusion for many years, ensures the safety of patients during infusion, and is popular with users.
Description
Technical field
This utility model relates to a kind of transfusion device, particularly relates to a kind of flame-arrester vent plug gravity transfusion device.
Technical background
Sell in the market, and people mostly are that flame-arrester vent plug is set on transfusion device at the transfusion device of hospital or family's use, when transfusion, nurse and relevant household will note the transfusion situation constantly, can not leave patient by the side of, because the liquid in the bottle is once drip off, as in time not finding, will cause the tube for transfusion blood back, the time one is long, and blood will be set in the tube for transfusion, for this reason, patient is caused unnecessary damages.
Summary of the invention
The purpose of this utility model is at above existing problems, and when a kind of can the liquid in transfusion device dripping off was provided, flame-arrester vent plug just can be blocked in the lower nozzle of transfusion device automatically, and transfusion is stopped, and so just can not cause the tube for transfusion blood back, and patient is damaged.
The purpose of this utility model is to realize like this, mainly comprise transfusion device and tube for transfusion, transfusion device is transparent cylindrical shape, is injection molded with igelite, top at transfusion device is connected with upper tubing, at its transfusion loam cake and transfusion device lower body, cement with plastic cement, in the transfusion device lower body, be provided with float, the body and function plastic cement cements under float loam cake and the float, is provided with pole at float loam cake periphery, makes float keep vertically moving up and down; Make the flame-arrester vent plug on the dop of float bottom, be blocked in the lower nozzle of hydrops groove, transfusion is stopped; Because the relation of gravity and suction makes the flame-arrester vent plug rubber deformation, and the tube for transfusion mouth of pipe below the hydrops groove is clogged.
Described float dop is a convex shape, and the rubber flame-arrester vent plug overlaps thereon, and the end of its rubber stopper is for thin and soft.
The utility model has the advantages that: simple in structure, scientific and reasonable, easy to use, creative, improved the trouble of very important person guard when infusing for many years, the safety when having guaranteed to give patient infusion is firmly got user's welcome.

The accompanying drawing piece number is represented:
1, upper tubing; 2, transfusion device; 3, plastic cement; 4, transfusion device loam cake; 5, transfusion device lower body; 6, float loam cake; 7, pole; 8, plastic cement; 9, float lower body; 10, float; 11, float dop; 12, rubber flame-arrester vent plug; 13, hydrops groove; 14, following tube for transfusion.
The specific embodiment
Referring to Fig. 1 Fig. 2,, describe in further detail below in conjunction with the drawings and specific embodiments.Mainly comprise transfusion device and tube for transfusion, transfusion device 2 is transparent cylindrical shape, be injection molded with igelite, be connected with upper tubing 1 on the top of transfusion device 2, at its transfusion device loam cake 4 and transfusion device lower body 5, cement with plastic cement 3, in transfusion device lower body 5, be provided with float 10, float loam cake 6 cements with float lower body 9 usefulness plastic cements 8, is provided with pole 7 on float loam cake 6 peripheries, makes float 10 maintenances vertically move up and down, make flame-arrester vent plug 12 on the float 10 bottom dops 11, be blocked in the mouth of pipe of the bottom tube for transfusion 14 of hydrops groove 13, transfusion is stopped.Because the relation of gravity and suction makes flame-arrester vent plug 12 rubber deformations, tube for transfusion 14 mouths of pipe below the hydrops groove 13 are clogged.Float dop 11 is a convex shape, and rubber flame-arrester vent plug 12 overlaps thereon, and the end of its rubber stopper 12 is for thin and soft.Make when stopping up reliable.
Claims (2)
1, a kind of flame-arrester vent plug gravity transfusion device, mainly comprise transfusion device and tube for transfusion, it is characterized in that: transfusion device is transparent cylindrical shape, is injection molded with igelite, top at transfusion device is connected with upper tubing, at its transfusion loam cake and transfusion device lower body, cement with plastic cement, in the transfusion device lower body, be provided with float, the body and function plastic cement cements under float loam cake and the float, is provided with pole at floating loam cake periphery, makes float keep vertically moving up and down; Make the flame-arrester vent plug on the dop of float bottom, be blocked in the lower nozzle of hydrops groove, transfusion is stopped; Because the relation of gravity and suction makes the flame-arrester vent plug rubber deformation, and the tube for transfusion mouth of pipe below the hydrops groove is clogged.
2, flame-arrester vent plug gravity transfusion device according to claim 1, it is characterized in that: described float dop is a convex shape, and the rubber flame-arrester vent plug overlaps thereon, and the end of its rubber stopper is for thin and soft.
