Abstract
The utility model relates to an automatic monitoring apparatus for drip quantity of infusion, composed of a monitoring part and an alarm, wherein, the alarm can adopts the existing various audible and visual alarms. The monitoring part comprises an upper and a lower hanger frames which are connected through a plurality of springs, and simultaneously, a mechanical movement amplifying device is arranged between the two hanger frames. The input end of the mechanical movement amplifying device are respectively connected with the two hanger frames, and the output end of the mechanical movement amplifying device is provided with a movable contact. The movement trace of the movable contact is provided with a fixed contact. The utility model has the advantages of simple structure, mature technology, easy operation, strong anti-interference ability and reliable work.
Description
This utility model relates to a kind of amount of infusion automated watch-keeping facility.
Infusion treatment is a kind of popularizing very much and effective medical procedure, when still infusing, after liquid flows to end in the liquid bottle, as can not in time taking measures, can bring danger to the patient.In traditional infusion treatment process, need nurse or family numbers of patients to monitor remaining liquid measure in the liquid bottle at any time so that in time change the liquid bottle or stop transfusion.Because it is infusion process is long usually, and in case carelessness can cause serious consequence, the follow-up work of infusion process consumes useless energy very much, especially infuses at night, useless more refreshing.For realizing the automatic supervision of infusion process, the existing automatic monitor of a kind of amount of infusion, it is that an inducer is established in appropriate position on the liquid bottle, and be provided with corresponding signal processing circuit and alarm device, when liquid level dropped to this position, inducer sent signal, started alarm device after processing of circuit, its weak point is that this inducer is subject to surrounding and disturbs, and monitors and reports to the police not accurate enough.
The purpose of this utility model is to provide a kind of novel infusion amount automatic monitoring device, can improve the accuracy of amount of infusion monitor alarm effectively.
The technical scheme that this utility model adopted is that this amount of infusion automatic monitoring device is made up of monitor portion and alarm, and wherein alarm can adopt existing various audible-visual annunciators.Described monitor portion comprises upper and lower two suspension brackets, utilize several springs to connect between two suspension brackets, simultaneously, be provided with a mechanical movement amplifying device between two suspension brackets, the input of this mechanical movement amplifying device is connected with two suspension brackets respectively, establish a movable contact at its outfan, and on the movement locus of this movable contact, establish a fixed contact, connect with described alarm by the contactor that this two contact is formed.During use, over sling is hung on the drip stand, the liquid bottle hangs over down the suspension bracket below, liquid is more in when beginning transfusion liquid bottle, under the effect of its weight, above-mentionedly be connected in two springs elongations between the suspension bracket, distance between the upper and lower suspension bracket increases, along with the carrying out of infusion process, the weight of liquid bottle reduces gradually, the distance between two suspension brackets correspondingly reduce, can drive the movable contact motion by described mechanical movement amplifying device, when movable contact touches fixed contact, promptly can start warning circuit, finish actuation of an alarm.
Advantage of the present utility model is that it is simple in structure, and technical maturity is easy to implement.Its capacity of resisting disturbance is strong simultaneously, reliable operation.
Below in conjunction with drawings and Examples this utility model is further described.
Accompanying drawing 1: structural representation of the present utility model.
Embodiment: this routine described amount of infusion automated watch-keeping facility is made up of monitor portion and alarm, and wherein the structure of monitoring arrangement comprises and utilizes four springs 4 to connect between over sling 5 and following suspension bracket 1, two suspension bracket as shown in Figure 1.The mechanism kinematic amplifying device that adopts in this example is a rack and pinion drive, its middle rack 8 is hinged on down on the suspension bracket 1, the axle of gear 7 is installed on the over sling 5, movable contact 6 vertically is fixedly mounted on the axle of gear 7, also be provided with the contact supporting 9 of a circle with movable contact 6 corresponding positions, edge at this contact supporting 9 is provided with a plurality of contact receptacle 2, and fixed contact 3 can be plugged on wherein arbitrary jack 2 in this example.Contactor and alarm that above-mentioned movable contact 6 and fixed contact 3 are formed are connected in series.
