Abstract
The invention relates to a non-setting multi-dose lever trigger type transfusion reminding device. The non-setting multi-dose lever trigger type transfusion reminding device comprises movable hooks, a buzzer and a buzzer trigger switch, and is characterized in that a horizontal lever is horizontally arranged on a bearing object through the supporting point of the lever; a weight is arranged at one end of the horizontal lever at a fixed position away from the supporting point of the lever; the more than one movable hook is arranged at the other end of the horizontal lever at different positions away from the supporting point of the lever; the buzzer trigger switch is arranged at one end or the other end of the horizontal lever; the reminding device is characterized in that 1, a reset spring is not used, so that spring fatigue is avoided, the error is very small, and precise reminding can also be achieved after long-time service; 2, the plurality of hooks are arranged at a time according to liquids of different weights, so that once arrangement lifelong service is achieved; 3, the sensitivity is relatively high, and timely reminding is achieved; 4, the structure is simple, the cost is low, the failure rate is low and the service life is long.
Description
Technical field
The present invention relates to a kind of medical instruments, particularly one and exempt from setting multiple dose lever trigger-type infusion warning device.
Background technology
Chinese patent, infusion warning device disclosed in the patent No. 2013105003444, it comprises box body, back-moving spring is provided with in box body, be respectively equipped with hook box body is upper and lower, between back-moving spring and lower draw-bar, be provided with trigger switch, and in box body, be provided with photoelectric alarm device, when in infusion bottle, liquid is totally lost, during box body weight saving, box body occurs to top offset relative to upper hook, and this displacement touches trigger switch conducting, photoelectric alarm device sends sound and light signal, reminds patient and family members.Otherwise trigger switch ends, and photoelectric alarm exports without sound and light signal, is transfusion state.But this infusion warning device exists following defect: 1, back-moving spring easily produces fatigue, use after a period of time, easily produce error, cause reminding too early or excessively late.2, alarm set can only adapt to a kind of liquid bottles of weight, can not unify to be suitable for for liquid bottles that is not of uniform size, that vary in weight, very inconvenient in using.
Summary of the invention
Setting multiple dose lever trigger-type infusion warning device is exempted from order to the defect overcoming background technology the invention provides one.
The technical scheme that the present invention solves its technical problem is:
One exempts from setting multiple dose lever trigger-type infusion warning device, it comprises: Removable hook, buzzer, buzzer trigger switch, it is characterized in that: on a supporter, be horizontally disposed with a horizontal lever by balance pivot, in the fixed position of one end of horizontal lever distance balance pivot, counterweight is set, more than one Removable hook is set respectively at the diverse location of the other end distance balance pivot of horizontal lever, buzzer trigger switch is set in one end of horizontal lever or the other end.
Aforesaid horizontal lever is horizontally disposed with, and two ends can rotate up and down an angle respectively, and its length of one end horizontal lever being arranged counterweight is less than the one end arranging Removable hook.
Aforesaid horizontal lever is set directly on described supporter.
Aforesaid horizontal lever is arranged on top or the below of described supporter.
Aforementioned levels lever is first arranged on bonded block, and bonded block is movably fixed on described supporter again.
Aforesaid bonded block is a sleeve pipe, described bonded block has the transverse shape of the transverse shape of a part, external diameter and bonded block at least, internal diameter adapts, described bonded block cover on a support, and is provided with holding screw on bonded block.
Aforesaid more than one Removable hook is fixedly installed on the other end of lever respectively by connecting ring.
Aforesaid more than one Removable hook is movably arranged on horizontal lever respectively by connecting ring, sleeve, holding screw, and the relative position of each Removable hook on horizontal lever is adjustable.
Aforesaid more than one Removable hook is combined with horizontal lever by diminished shaft, sleeve.
We know, no matter any infusion warning device, be all go to trigger alerting signal by weight change, this invention lever principle combines with advanced photogenerator, simplifying the structure complexity.During use, one of them hook of multiple hook is upper only hangs an infusion bottle, according to lever law: power × power arm=resistance × resistance arm: the hook away from balance pivot hangs lighter infusion bottle, hook near balance pivot hangs heavier infusion bottle, as long as select corresponding hook according to different infusion bottle empty bottle weight, when liquid is totally lost, liquid bottles weight, lever right-hand member falls, trigger switch conducting, buzzer will send acoustoelectric signal and remind, the setting position of each Removable hook can calculate according to lever law, or obtain by test method, once adjust, life-time service.
The invention has the beneficial effects as follows: 1, because this alarm set does not use back-moving spring, there is not spring fatigue, error is little, even if use for a long time, also can reach accurate prompting.2, multiple hook can be set according to the liquid of multiple Different Weight simultaneously, once arrange, use all the life.3, the lever shift length caused due to weight change is comparatively large, so sensitivity is higher, remind in time, error is less.4, structure is simple, with low cost, failure rate is low, long service life.
