Abstract

The utility model relates to an infusion monitoring sensor. A spring acts up and down in a plastic sleeve pipe, the sensor senses, or the power is cut off, or the current is switched on according to the weight change of an infusion bottle, and thereby, an alarm stops or works. The infusion monitoring sensor solves the problem that patients or nursing staff monitor the infusion, automatically monitors the automatic alarm, and can not cause unnecessary troubles by people' s drowsiness and inadvertency. The infusion monitoring sensor has the advantages of simple structure and low cost, is suitable for popularization and application in hospitals, and is a good assistant for medical care personnel.

Description

The monitoring infusion pick off

Affiliated technical field

This utility model relates to a kind of medical transfusion supervising device, especially a kind of monitoring infusion pick off.

Background technology

At present, transfusion is hung in medical treatment, mostly is patient or family members monitoring, informs after medicinal liquid is totally lost that the nurse handles again, and this has many drawbacks.Patient oneself monitoring, owing to infuse, handicapped, be difficult for summoning to court the medical care person of going into, family members' monitoring needs personnel to accompany and attend in the front, and the sleepy general idea of patient or family members more can be incured loss through delay the monitoring process of transfusion, and cause unnecessary trouble sometimes.Though certain monitor device has also been used in some area, structure is loaded down with trivial details, and is also reliable inadequately, is difficult for promoting the use of.

Summary of the invention

The utility model proposes a kind of monitoring infusion pick off, its property simple and reliable for structure is strong, preferably resolves the automatic monitoring problem of medical transfusion.

The technical scheme that its technical problem that solves this utility model adopts is: install following two groups of spring structures respectively in a sleeve pipe, last one group of spring structure has a hollow guide rod, the guide rod upper end connects a direction and carries button, on the guide rod, in, following each point, a crosspiece bar is installed respectively, a conductive ring is installed in the lower end of guide rod, conductive ring is spaced from each other by two halves and insulating foil and an insulating roundel are formed, roundel by two fastening nuts it with tightly fixing of guide rod, two half conductive rings are connected a lead respectively, in guide rod, pass the guide rod wall from guide rod upper end and carry button and draw.Outside the guide rod, engage a gear spring of suit; Next organizes spring structure, have about a screw mandrel runs through, long filament bar lower end is a fishhook ring, the screw mandrel of an adjusting of middle part suit, and the screw mandrel upper end is by fastening guide ring of silk medicated cap and conductive reed, outside the adjusting screw mandrel, sensing spring of suit, the sleeve pipe upper end is installed a loam cake respectively, and a lower cover is installed in the lower end, loam cake is that it is fixed with sleeve pipe by hanging, and lower cover is fixed it by staple with sleeve pipe.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is a structure principle chart of the present utility model.

Among the figure, 1. hang and be, 2. carry button, 3. draw lead, 4. loam cake, 5. guide rod, 6. engage a gear spring, 7. roundel, 8. conductive ring, 9. conductive reed, 10. guide ring, 11. regulate screw mandrels, 12. sensing spring, 13. staples, 14. lower covers, 15. screw mandrel, 16. fishhook rings, 17. nuts, 18. the crosspiece bar, 19. sleeve pipes, 20. pilot holes.

Operation principle of the present utility model is such: when hanging the bottle that fills with transfusion below the screw mandrel, because the big relation of weight, conductive reed slides along casing wall, outage at this moment, and alarm quits work, in infusion bottle, there is not transfusion, when being empty bottle, bottle is very light, and conductive reed just upwards slides into the position of conductive ring along casing wall, at this moment conducting the electric current of the lead that connects on the conductive ring, this promptly can cause alarm work.

The specific embodiment

In the drawings, carrying button (2) upwards mentions, when treating that crosspiece bar (18) is higher than loam cake (4), rotating 90 ° can fix, because pilot hole (20) is a slotted eye, when the little crosspiece bar (18) on the guide rod (5) when the major diameter direction of pilot hole (20) upwards proposes, rotated 90 °, the length of little crosspiece bar (18) just can make cross bar can not fall greater than the minor axis of oval pilot hole (20).Because plural little crosspiece bar (18) is housed above the guide rod (15), so when carrying that button (2) and guide rod (5) are upwards mentioned and when locating, just having the adjusting of a plurality of gears, thereby can adapt to the sensing of different infusion bottles, bag weight.Conductive reed (9) is a metal spring leaf that can allow current lead-through, when conductive reed (9) and two conductive rings (8) when contacting, can the conducting electric current, and impel alarm work.Regulating the effect of screw mandrel (11), mainly is when crosspiece bar (18) is located, and regulates the anastomosing best opportunity of the same conductive ring of conductive reed (8).Sleeve pipe (19) is the plastic tube of a circle, also can make shape arbitrarily.

Claims

1, a kind of monitoring infusion pick off, by spring, conductive metal sheet, sleeve pipe, block, angle and be, compositions such as guide rod, it is characterized in that: in a sleeve pipe (19), install respectively, following two groups of spring structures, last one group of spring structure has a hollow guide rod (5), guide rod (5) upper end connects a direction and carries button (2), on the guide rod (5), in, following each point, a crosspiece bar (18) is installed respectively, a conductive ring (8) is installed in the lower end of guide rod, conductive ring (8) is spaced from each other by two halves and insulating foil and an insulating roundel (7) are formed, roundel (7) by two fastening nuts (17) tightly fixing of its same guide rod (5), two half conductive ring (8) are connected a lead (3) respectively, in guide rod (5), pass the guide rod wall from guide rod (5) upper end and carry button (2) and draw.Outside the guide rod (5), an engage a gear spring of suit (6); Next organizes spring structure, have about a screw mandrel (15) runs through, long filament bar (15) lower end is a fishhook ring (16), the screw mandrel (15) of an adjusting of middle part suit, screw mandrel (15) upper end is by fastening guide ring of silk medicated cap (17) (10) and conductive reed (9), regulate outside the screw mandrel (11), a sensing spring of suit (12), sleeve pipe (19) upper end is installed a loam cake (4) respectively, a lower cover (14) is installed in the lower end, loam cake (14) is that (1) is fixing its same sleeve pipe (19) by hanging, and lower cover (14) is fixing its same sleeve pipe (19) by staple.
