Abstract
The utility model discloses a medical infusion alarm, it comprises electron acousto-optic generator and infusion bottle hanger, and the acousto-optic circuit has a normally open on & off switch to fix on the infusion bottle hanger, and the couple of hanger passes through the lifter and links to each other with extension spring, and the lifter has a contact that can collide above-mentioned on & off switch. When the liquid level in the bottle is lowered, the lifting rod and the contact are lifted by the action of the extension spring, when the residual liquid is lowered to a certain amount, the contact collides with the switch key to close the switch key, and the circuit is communicated to automatically send out an alarm signal.
Description
This utility model is the liquid level alarm device about medical Transfusion device.
During to patient infusion, must keep a close eye on liquid level in the bottle, when medicinal liquid was about to be totally lost, in time liquid feeding or removal syringe needle were avoided in the air input body.This liquid level generally all need have the special messenger to keep an eye on, and a carelessness tends to have an accident slightly, and is very inconvenient.
The purpose of this utility model provides a kind of infusion alarm, and it can send sound and light signal automatically when the infusion bottle inner liquid medicine will finish, and reminds the nursing staff in time to handle, and avoids causing danger.
This utility model infusion alarm is made up of electronic acoustooptic generator and infusion bottle hanger, acousto-optic circuit has an on ﹠ off switch of often opening to be fixed on the infusion bottle hanger, the hook of hanger lower end links to each other with extension spring by elevating lever, elevating lever is provided with one can make its closed contact with above-mentioned on ﹠ off switch collision, this contact be fixed on the synchronization-moving sleeve of elevating lever on, sleeve is by the pushnut location of the stage clip of upper end and lower end.When the last extension of hook hangs infusion bottle, elevating lever and contact move down, on ﹠ off switch disconnects, along with liquid level in the infusion bottle descends, action of gravity reduces, and elevating lever is risen by the effect of extension spring gradually, when residual liquid in the bottle reduces to a certain amount of, contact brushes up against on ﹠ off switch and on ﹠ off switch closure, circuit is connected, and audible-visual annunciator promptly sends sound and light signal.Pushnut is used to regulate the position of contact, can regulate the position of contact in advance by the standard residual liquid.
In sum, this utility model can send 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, and easy to use, patient is relieved, and the care-giver saves worry.
Below in conjunction with description of drawings embodiment of the present utility model.
Accompanying drawing is the embodiment of this infusion alarm.
As shown, this utility model infusion alarm is made up of infusion bottle hanger 8 and electronic acoustooptic generator 12.Acousto-optic circuit has an on ﹠ off switch of often opening 11 to be located in the infusion bottle hanger, the upper end of hanger is provided with suspension ring 1, and there is hook 7 lower end, and hook links to each other with an extension spring 2 by elevating lever 4, elevating lever is provided with sleeve 5 outward, telescopic upper end is provided with stage clip, and the last washer 9 of stage clip is fixed on the elevating lever 4, and lower gear plate 10 is fixed on the upper end of sleeve 5, in the present embodiment, lower gear plate 10 is held concurrently simultaneously and is contact, and telescopic lower end and pushnut 6 offset, and this nut is threaded with elevating lever.By the turn nut, sleeve is moved axially, on elevating lever to regulate the position of contact 10.This alarm can be suspended on the infusion bottle that leaves a small amount of residual liquid on the hook before using in advance, by turn nut 6, sleeve is moved up or down, and collides until contact 10 and on ﹠ off switch, and acousto-optic generator 12 sends sound and optic signal and gets final product.After once adjusting finishes, all applicable to the infusion bottle of same model, needn't regulate at every turn.The effect of stage clip 3 is to make the locking position of sleeve on elevating lever 4 in this device, can only move up and down under the effect of nut 6, does not rock and do not have radially.Acousto-optic generator 12 can adopt the common doorbell that display lamp is housed.
