Abstract
The utility model relates to a new electronic automatic caller for transfusion. The utility model is a device which can automatically send out audible and visual alarm signals when the transfusion is about to finish, and brings convenience for the nursing personnel to timely treat. The device has an integral structure, and is conveniently matched with an existing transfusion frame. The utility model is characterized in that the utility model is provided with a drive circuit whose conducting operation is controlled through a gravity switch comprising an upper and a lower suspension hooks connected with a tension spring through respective suspension plates; a movable contact sheet can move following the stretched length of the spring, and the static contact on the just top of the movable contact sheet can be conducted. The utility model has active meaning for improving the care level and reducing the medical negligence.
Description
This utility model belongs to a kind of medical aid, is used for giving light and sound equipment prompting when transfusion (blood) process will finish, to prevent the generation of transfusion accident.
Chinese patent 85203127 discloses a kind of medical infusion automatic monitoring device.Comprise signal lights, electric bell display alarm circuit and infusion set, to place signal lights, the electric bell of observation ward to be connected by the contact switch of lead with the ward infusion set, the compression spring of a support infusion bottle is housed in the infusion set, a liquid bottle pallet is fixed in the compression spring end, liquid changes pallet 5 in the bottle, above-mentioned spring is synchronous shift together, floatless switch contacting on the pallet, this scheme infusion support must be set up pallet, and report to the police and partly separate with pallet, implementing to use has inconvenience.
This utility model at above-mentioned deficiency provide a kind of the transfusion (blood) support directly hang with the liquid bottle, with alarm element be the automatic pager of electronic infusion of one.
Realize goal of the invention in the following manner.
This utility model comprises that one is controlled its anastomosing one group of electronic drive circuit by gravity switch, and the outfan load of circuit is sound device and display lamp, also comprises the set of cells supporting with it, on and off switch and shell thereof.Gravity switch has two hanged hooks, and the upper end hangs over infusion support, and the lower end hangs with infusion bottle.By being connected an extension spring with separately link plate, a movable contact spring is fixed in infra hanged hook link plate and spring junction to hanged hook, is a metal good conductor respectively up and down.Two stationary contacts between the supply line that is serially connected in electronic drive circuit, the uncorrelated company of moving part that lower draw-bar and spring are formed and housing are being arranged under the shell wall above this contact.
Hang infusion bottle at this utility model lower draw-bar, when the bottle inner liquid medicine drops to the precalculated position, movable contact spring is along with bottle is improved by spring, movable contact spring contact stationary contact, electronic drive circuit energized, audio device and signal lights all provide alarm signal, and the prompting nursing staff in time handles, can thoroughly stop to infuse end and not pull out the malpractice that syringe needle brings, simultaneously can alleviate medical worker's workload, when must the light blocking medicine infusing, strong assistant more is absolutely necessary.
Accompanying drawing 1 is this utility model example structure sketch map;
Accompanying drawing 2 is the electronic drive circuit power control circuit.
Introduce ins and outs below in conjunction with accompanying drawing
In the accompanying drawing 1, whole parts of the present utility model are installed in the rectangular enclosure 10, an electronic drive circuit plate 3, its output loading end connects buzzer 2 and signal lights 9, the 12(11 of hanged hook up and down of gravity switch) through connected link plate 5(13), be connected to each other by an extension spring 6, following link plate 13 has a movable contact spring 1 with spring 6 junctions, the shell internal fixation has two stationary contacts 7 that are serially connected on the electronic drive circuit above movable contact spring 1, when the infusion bottle on the lower draw-bar when liquid level drops to predetermined value, movable contact spring 1 is with moving on the spring, contact with stationary contact 7, connect the power supply of electronic drive circuit, detection system is sent the sound and light alarm signal, notifies the nursing staff in time to handle, 4 is on and off switch among the figure, 8 is set of cells, and the uncorrelated company with housing of the formed moving part of lower draw-bar and spring can move up and down with the lower draw-bar load capacity.
This utility model reduces malpractice for improving the medical treatment and nursing level, reduces nursing staff's workload and has positive effect.
Claims (1)
1, the automatic pager of a kind of electronic infusion, comprise that one is controlled its anastomosing one group of electronic drive circuit by gravity switch, its outfan load is sound device and display lamp, also comprise set of cells, on and off switch and shell thereof, it is characterized in that: described gravity switch has two hanged hooks, hanged hook is respectively by being connected an extension spring with separately link plate up and down, a movable contact spring is fixed in infra hanged hook link plate and spring junction, two stationary contacts between the supply line that is serially connected in electronic drive circuit respectively, the uncorrelated company of moving part that lower draw-bar and spring are formed and housing are being arranged under the shell wall above this movable contact spring.
