Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment:

Shown in Fig. 1-4, this sick bed angle control alarm mainly is made up of cover 1, bottom 2, hummer 7, red alarm lamp 8, yellow alarm lamp 9, battery 11, ball switch 13, pcb board 14, and cover 1 and bottom 2 snap together; Wherein, be provided with audible alarm window 15, pilot lamp window annunciator 16, low-voltage icon 17, angle indication icon 18 on cover 1 surface, hummer (SP) 7, ball switch (S1, S2) 13, power switch 4, pcb board 14 are installed in cover 1, wherein on pcb board 14, be provided with control chip (U1) 20, red alarm pilot lamp (LED D2) 8, yellow alarm pilot lamp (LED D1) 9, in bottom 2, be provided with battery compartment 19, be provided with battery 11 in battery compartment 19, battery 11 connects power switch 4 and pcb board 14.

Purposes:

This product can place on the different sick beds, is lower than 30 when spending when the head of a bed position of sick bed drops to, and can produce sound and flash caution lamp and report to the police.Confirmed to adopt and raised the force ventilated mode of the head of a bed and can help to reduce probability at the hospital infection acquired pneumonia.This product can be pointed out and be improved the quality of looking after this class patient.

Circuit (as shown in Figure 5):

When being applied on the sick bed, this device is gone up the plane and can be installed with any parallel sided of the sick bed head of a bed, and when angle is lower than 30 when spending, two ball switch (S1, S2) are connected simultaneously, and circuit working is sounded and light warning; When angle was spent greater than 30, one of them ball switch disconnected, and entire circuit is in the OFF state, meaned first sick bed angle OK.

The circuit working principle:

Two ball switch (S1, S2) that become 30 degree angle symmetries to place with surface level are connected the back with having sound, the circuit of light warning connects, when two switches are in 30 degree angles when following simultaneously, ball switch (S1, S2) is all at the ON state, then entire circuit is in running order, send blinking light and audible alarm, more than any one ball switch wherein is in 30 degree angles when (containing), this ball switch that is in 30 degree angles above (containing) will be in the OFF state, and entire circuit will be in open-circuit condition and no longer work.Sound and blinking light are reported to the police and are also stopped thereupon.

Surpass 1 minute as the accumulative total time of fire alarming, then quiet 1 minute, its objective is that for power saving this product battery can reach 6 months serviceable life at least.

When supply voltage is lower than 2.3V, the amber light flicker, flicker frequency 0.5HZ dodges (1 second is bright, goes out in 1 second), reminding user to replace battery.

Use velcro (VELCRO colludes face (gum)) 10 to be pasted on the head of a bed, use velcro (VELCRO hair side (gum)) 10 to be pasted on bottom 2, the dismounting easy maintenance is simple.
