Abstract

The utility model relates to an automatic alarm for infusion. The utility model comprises a weight indication, an alarm tuning indicator, an alarm circuit with acoustic-optic display; according to the changes of the liquid weight, the utility model adjust the distance between a dry spring tube and a magnet; when the liquid weight is lightened, the magnet is coincident with the dry spring tube under the action of the spring tension and the circuit is switched on; so the utility model can achieve the goal of automatic alarm. Having the advantages of simple structure, convenient operation and precision, the utility model can be suitable for any hung containers for transfusion with different weights and liquid which are sealed in bottles and can be used widely for automatic warning in the hospital infusion.

Description

Automatic alarm for infusion

This utility model belongs to medical instruments field, is specially adapted to the hospital patient transfusion and reports to the police automatically.

Before this utility model, in traditional infusion process, when no those who accompany the bed guards, the bad grasp of time that fluid drips is most is to monitor with estimated time or patient oneself generally speaking, when liquid is about to drip to the greatest extent, near the ward beeper switch that is provided with the drawing sick bed, remind the nurse to remove, when being in a bad way, not only inaccurate but also inconvenient as if patient.

The purpose of this utility model is to provide a kind of can be applicable to the transfusion bottle of any Different Weight and the automatic alarm for transfusion of sealing bottling liquid, realizes accurately giving the correct time, to alleviate nursing staff's labor intensity.

Of the present utility model is to realize like this, an autoalarm is set, it is by the weight indicating structure, report to the police tuning indicating structure and acousto-optic display alarm formed, wherein, extension spring 7 in the weight indicating structure, the one end is fixed on extension spring chute 9, top and support link 1, be fixed on jointly on the shell wall 13, the other end of extension spring 7 is connected with extension spring interlock sheet 5, Magnet 8 is fixed on the extension spring double-action plate 5 with weight pointer 2, and the lower end of extension spring double-action plate 5 is provided with transfusion bottle hook 6, and weight indicating graduation dish 14 is positioned at shell wall 13 surfaces and goes up the position that can overlap with weight pointer 2, side at the weight indicating structure is provided with the adjusting indicating structure of reporting to the police, tongue tube 12 in this structure is fixed on the slide block 11 in the chute 10, and warning pointer 3 also is fixed on the slide block 11, with warning pointer regulating handle 4 interlocks, audible-visual annunciator 15 can be the alarm of selling on the market, also can be the original teleseme in ward; Connection between weight indicating structure and the acousto-optic display alarm is: weight pointer 2 overlaps with warning pointer 3, and Magnet 8 is connected audible-visual annunciator 15 with tongue tube 12 adhesives.During operation, hang up transfusion bottle, extension spring is subjected to the effect of bottle weight, and the weight pointer is moved down by zero graduation, is parked on a certain scale, regulates regulating handle, makes the indication of warning pointer and weight pointer on identical graduation.Liquid pour transfusion bottle into, the weight pointer continues to be displaced downwardly to a certain position.In infusion process, liquid constantly minimizing weight pointer under the effect of tension spring tension begins slowly to move up and is approaching gradually with the warning pointer, when between two pointers distance equal to install between Magnet and the weight pointer apart from the time, at this moment, Magnet just in time overlaps with tongue tube, tongue tube is subjected to the effect of Magnet magnetic force by adhesive, circuit turn-on, alarm device begins to report to the police, meanwhile, near ward beeper (ward existing equipment) switch that is provided with the sick bed is connected in the relay adhesive, and the acousto-optic display device of nurse's night shift room is made corresponding reflection, and prompting nursing staff liquid continues to add liquid or remove pin with needing to the greatest extent, when liquid all drips off, two pointers refer to again take empty bottle on identical scale, and the weight pointer is subjected to the pulling force of extension spring to return zero.When using the sealing bottling liquid, one hangs up bottle weight pointer will indicate downwards till can not be descending, at this moment, answer tuning warning pointer tuning handle, make its indication (be carved with different scales with 5000ml plastic bottle enclosing liquid) on the warning scale of having indicated equally when the distance of two pointers equals mounting distance between Magnet and the weight pointer as 500ml vial enclosing liquid, alarm device begins to report to the police, thereby reaches the purpose that transfusion is reported to the police automatically.

10, tongue tube chute

11, slide block

12, tongue tube

13, shell wall

14, weight indicating graduation dish

15, alarm

16, ward beeper

When transfusion liquid was about to drip to the greatest extent, alarm 15 sent alarm signal, connected ward beeper 16 by the C22 place jack in the alarm 15, and signal is reached nurse's night shift room, and alarm 15 adopts dc source.

This device is easy to use, and cost is low, and is accurate, can be suitable for the transfusion special-purpose bottle of any Different Weight.
