Abstract
The utility model relates to an adjustable alarm system for perfusion, which comprises a suspension linkage of the perfusion bottle and an acousto-optic generation circuit. The structure of the utility model as follows:(1) the suspension linkage of the perfusion bottle comprises a cover, a screw bolt, an extension spring and a hooker; the screw bolt with an adjustable knob is arranged in the cover and a mobile nut is connected with the screw bolt; two extension springs are linked with each end of the mobile nut respectively and the lower end of the extension spring is connected with a hooker through an elevating lever;(2) the acousto-optic generation circuit is arranged on the back of the cover, and control power supply and supply suspension by the normally open switch arranged at the bottom of the elevating lever. Thereby, accompanying the decrease of the liquid medicine in the bottle, the elevating lever will lift gradually by stress from the extension spring. To a certain degree, the acousto-optic generation circuit will close and the connected circuit will send an acousto-optic signal to warn the nursing personnel to handle and avoid accidents.
Description
Technical field:
This utility model belongs to medical instruments field, and a kind of adjustable infusion alarm is provided.
Background technology:
It is a kind of common medical procedure that bottle is hung in transfusion.During patient infusion, the nurse personnel must keep a close eye on liquid level in the transfusion bottle.When medicinal liquid is about to be totally lost, in time liquid feeding or removal syringe needle, otherwise air is imported in the body easily.So present stage all needs the entourage to keep an eye on transfusion bottle during patient infusion, otherwise as easy as rolling off a log having an accident.
Summary of the invention:
The purpose of this utility model provides a kind of adjustable infusion alarm, and it can send sound and light signal automatically when the infusion bottle inner liquid medicine is about to drip off, thereby reminds the nursing staff in time to handle.
The technical solution of the utility model is: a kind of adjustable infusion alarm, comprise infusion bottle suspension arrangement and acousto-optic generation circuit, it is characterized in that described infusion bottle suspension arrangement is made up of parts such as shell, screw rod, extension spring, hooks, shell is provided with is with graduated panel, screw rod is installed in the shell, and its upper end is provided with the adjusting knob that can rotate with its disjunctor; Be connected with a travelling nut in the screw rod, the bottom, two ends of travelling nut respectively connects an extension spring, and the bottom of this extension spring connects a hook by elevating lever; Acousto-optic generation circuit is installed on the back of shell, and it has a switch of often opening to be fixed on the elevating lever position of infusion bottle suspension arrangement.
Like this, when hanging infusion bottle in the hook, elevating lever moves down, the on ﹠ off switch of acousto-optic generation circuit disconnects, and along with the minimizing of infusion bottle inner liquid medicine, action of gravity reduces, elevating lever is risen by the effect of extension spring gradually, arrive to a certain degree back acousto-optic generation contactor closure, circuit is connected, and sends sound and light signal.The rotation adjusting knob is used to regulate the pulling force of extension spring, sends alarm signal with the infusion bottle that adapts to Different Weight or when being adjusted at the Different Weight residual liquid.
In sum, infusion alarm provided by the utility model sends sound and light alarm automatically when infusion bottle residual liquid amount reduces to a certain amount of, reminds the nursing staff in time to handle, and avoids unexpected.It is simple to operate, easy to use, uses when being applicable to hospital, family transfusion.
Description of drawings:
Fig. 1 is the Facad structure sketch map of this adjustable infusion alarm.
Fig. 2 is the internal structure sketch map of this adjustable infusion alarm.
Fig. 3 is the side structure sketch map of this adjustable infusion alarm.
The specific embodiment:
As shown in Figure 1, this adjustable infusion alarm is made of infusion bottle suspension arrangement and acousto-optic generation circuit.Described infusion bottle suspension arrangement is made up of parts such as shell 1, screw rod 2, extension spring 4, hooks 7.Shell is provided with is with graduated panel 8, and screw rod 2 is installed in the shell 1, and the upper end is connected with adjusting knob 3, and this adjusting knob can drive screw rod 2 and rotate synchronously.Be connected with a travelling nut 5 in the screw rod 2, two side lower parts of travelling nut respectively connect an extension spring 4.The bottom of extension spring 4 connects a hook 7 by elevating lever 6.Acousto-optic generation circuit 9 is installed on the back of shell, and it has a switch of often opening to be fixed on elevating lever 6 positions of infusion bottle suspension arrangement.
Like this, after hook 7 hangs up infusion bottle, extension spring 4 elongations, the switch of acousto-optic generation circuit disconnects.Along with the minimizing of residual liquid, the weight saving of infusion bottle, elevating lever 6 rises under the effect of extension spring 4, and then touches acousto-optic generation circuit, sends sound and light alarm.Described acousto-optic generation circuit can be connected to nurse's night shift room by circuit, is convenient to monitoring.
