Description
Technical Field
The invention relates to the field of ward calling equipment, in particular to a ward calling device convenient to use at night.
Background
With the development of scientific technology, the technological degree of facilities related to wards is also improved. The calling device is installed in a ward for a patient to remotely call a nurse or a doctor on duty, the calling device directly and quickly transmits the request of the inpatient to the nurse or the doctor on duty, and the calling device becomes an important device for enhancing communication between doctors and patients.
Because the basic medical resources of a hospital are limited, a plurality of patients and the accompanying family members of the patients generally live in the same ward, when the patients need to call medical care personnel or doctors at night, the indicator lamps in the ward are usually required to be turned on to find the corresponding calling devices, so that the rest of other patients is easily influenced, and the recovery of the state of illness of the patients is not facilitated; meanwhile, the indicating lamp is generally arranged at an entrance of a ward, a patient opens the indicating lamp and then presses a button or a key of the calling device, and if the patient cannot get out of the bed, the patient cannot accurately find the button of the calling device, so that the patient cannot call a nurse or a doctor in time, and the condition of delaying the treatment of the patient is easily caused.

Under the condition of weak and dim light at night, if a patient needs to call a nurse or a doctor by using the call button 2, the finger of the patient touches the temperature sensing module 3 on the surface of the call button 2, the temperature sensing module 3 sends the temperature value of the finger of the patient to the control module, because the temperature value of the finger of the patient is higher than the temperature of the call button 2, the temperature of the call button 2 does not cause interference, when the temperature value of the control module is greater than the temperature threshold value, the control module controls the motor corresponding to the first adjustable resistor 16 of the branch where the indicator lamp 5 is located to drive the adjusting sheet to rotate to reduce the resistance value, the current of the indicator lamp 5 in the branch is increased, the light brightness of the indicator lamp is enhanced, the patient is indicated to use the call button 2, meanwhile, only the light brightness of the indicator lamp 5 in part of the call button 2 is enhanced, and the patient does not need to, the rest of other patients in the same ward can not be influenced.
Before pressing call button 2, elastic airbag 13 pushes up call button 2 upwards, let support block 12 on the 8 cell walls of draw-in groove support on key seat 11, when patient pressed call button 2, the cell wall of draw-in groove 8 of call button 2 bottom inserts to patchhole 14, the cell wall extrudees sponge 15 in elastic airbag 13, extrude absorptive antiseptic solution in the sponge 15, layer 18 adsorbs the antiseptic solution that absorbs water on the cell wall simultaneously, the antiseptic solution soaks layer 18 that absorbs water and disinfects call button 2, patient is when touch press call button 2 simultaneously, layer 18 that absorbs water also can disinfect patient's finger, reduce bacterial growing in call button 2 gap.
Since the key bed 11 and the abutting block 12 separate the energized part of the wetted call button 2, the water absorbing layer 18 is not in communication with the energized part, and the call button 2 as a whole does not conduct electricity to cause a safety problem.
This embodiment is compared with the key switch of current direct built-in phosphor strip, the light reinforcing when needs use of this embodiment, call button 2's light intensity can throw light on to the minizone environment simultaneously, let patient directly find corresponding call button 2 and call out, need not to open the lamp in whole room, and when not using, call button 2's light weakens automatically, can not influence other patient's rest, current built-in phosphor strip's key switch light is too weak, patient is difficult to find the position at key switch place, if direct enhancement key switch's instruction luminous intensity, the sensitive patient's of light rest is influenced easily again, this embodiment still disinfects to patient's frequently-used call button 2 on the basis of overcoming this problem, reduce bacterial growing in call button 2 gaps.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
