Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
With reference to Fig. 1, infusion alarm of the present utility model is spring scale formula, and it comprises housing 17, for hanging infusion bottle, and possesses the spring carrier arm assembly of Telescopic, circuit board 24, metal needle 16, buzzer 25, warning lamp 26 and power supply 23.Circuit board 24 is arranged many strip metals graduation mark 30, gear shift pointer 31 and shift switch 22, wherein, what graduated metal line 30 represented is the infusion bottle capacity of present infusion, in the present embodiment, the range of graduated metal line 30 has 50ML, 100ML, 250ML, 500ML, 1000ML, therefore on circuit board 24, need be welded with 5 strip metal graduation marks 30 according to the distance of setting; It is movable that shift switch 22 can control gear shift pointer 31, and gear shift pointer 31 optionally contacts with wherein any one graduated metal line 30, and after gear shift pointer 31 contacts with graduated metal line 30, both form electric connection.Metal needle 16 and spring carrier arm assembly 1 are interconnected, can move up and down along with the flexible of spring carrier arm assembly, metal needle 16 also points to graduated metal line 30, when metal needle 16 contacts with same graduated metal line 30 with gear shift pointer 31, metal needle 16, circuit board 24, buzzer 25, warning lamp 26 and power supply 23 form closed warning circuit, buzzer 25 and warning lamp 26 work, and sound the alarm and alarm light.
Particularly, with further reference to Fig. 1 and Fig. 2:
The outer wall of housing 17 is provided with dial plate 21, and dial plate 21 center is provided with gear 9, and gear 9 overcoat has a root pointer 20, and what dial plate 21 surrounding showed is ponderal index.Link 18 is provided with on housing 17 top.
Spring carrier arm assembly comprises regulating wheel 1, adjustment screw mandrel 3, lever 4, the gimbal lever 12, hook 15, tooth bar 7, two heavy burden springs 6, two back-moving springs 13 and a back-moving spring 10; Wherein, regulating wheel 1 is rounded, is rotatably installed on housing 17, and some exposes outside housing 17, stirs for user; Adjustment screw mandrel 3 is threaded mutually with regulating wheel 1, and is fixedly connected on the center of lever 4, turn regulating wheel 1, and adjustment screw mandrel 3 and lever 4 can be made to move up and down; Two heavy burden springs 6 are suspended on the two ends of lever 4 respectively by catch 5, without in external force situation, naturally vertical; The gimbal lever 12 is fixedly connected on the lower end of two heavy burden springs 6, is then interconnected by two back-moving springs 13 and housing 17; Hook 15 is connected to the lower end of balance bar 12, and is positioned at outside housing 17; Tooth bar 7 is connected to the centre on balance bar 12 top, and engages each other with gear 9; Back-moving spring 10 one end is connected with tooth bar 7, and the other end is connected with balance bar 12, for improving the degree of engagement of tooth bar 7 and gear 9.When hook 15 hangs without weight, housing 17 is naturally vertical with spring carrier arm assembly, and pointer 20 points to the null gravity scale on dial plate 21; When having weight to be hung on hook 15, balance bar 12 and tooth bar 7 decline, and heavy burden spring 6 stretches, and gear 9 rotates, and drive pointer 20 to rotate; Because heavy burden spring 6 possesses elastic restoring force, when weight weight reduces, heavy burden spring 6 shrinks, and balance bar 12 and tooth bar 7 rise, and pointer 20 circles round.Therefore, when hook 15 hangs infusion bottle, can read infusion bottle weight from dial plate 21, transfusion process provides visual.
Metal needle 16 is arranged on the lower end of one of them heavy burden spring 6, and therefore, metal needle 16 also can occur along with the elongation of heavy burden spring 6 or contraction to decline and rise.When infusion alarm of the present utility model uses, first according to infusion bottle capacity, rotary shifting switch 22 is selected the gear of respective volume, when infusion bottle is hung on hook 15, heavy burden spring 6 is left behind, metal needle 16 is positioned at the below of the graduated metal line end of set wire, warning circuit not conducting.Along with the minimizing of bottle inner liquid medicine amount, the weight at drag hook 15 place reduces, and spring 6 is retracted gradually, pointer 16 gradually on move.When transfusion in bottle is finished, metal needle 16 contacts with graduated metal line 30 just, now circuit ON, and buzzer 25 gives the alarm, and warning lamp 26 luminescence, prompting medical personnel infuse end, process in time.
In sum, infusion alarm of the present utility model can at the end of transfusion, warning circuit conducting, and alarm, alleviate medical personnel's burden, for user provides convenient, embodying can the advantage of intelligent monitoring transfusion process, also possesses emergency alarm simultaneously, weighs article, provides the several functions such as illumination.
It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
