Description
Technical field
This utility model relates to a kind of portable noise-monitoring equipment for medical personnel.
Background technology
Environmental Protection Agency is recommended daytime, noise level was at 40～45dB (A), 35dB at night (A).The ICU 24h noise average level of research display both at home and abroad is at 55-65dB (A), and top level is 89-90dB (A), the scope that this numerical value can bear considerably beyond the mankind, and the rehabilitation to patient affects.Research display noise may result in the negative emotions such as agitation, terrified, anxiety psychologically for ICU patient, physiologically may result in the harmful effects such as insomnia, blood pressure rising, increased heart rate, fatiguability.84 examples are moved in NSICU patient and are carried out questionnaire survey by the sounds in week etc., and result shows: the patient of 66.75% affects sleep quality because of the noise of ICU, causes sleep disorder, and the situation of control noise is in sight.
At ICU, medical worker carrying out health propaganda and education and can effectively reduce noise, but can recover level before propaganda and education after a period of time, after propaganda and education, noise level reduces the most again again.Noise is topmost impact for the rest of staff, the interference of sleep.And, the noise monitor instrument designed for medical worker currently without a kind of specialty, there is vacancy in market.
Utility model content
The purpose of this utility model is to provide a kind of portable noise-monitoring equipment for medical personnel, medical worker may utilize this noise level indicator and detects the noise in ICU, when the noise in range is higher than normal value, warning reminding can be carried out, to ensure that patient is in a health, the beneficially environment of rehabilitation.
For solving above-mentioned technical problem, this utility model provides a kind of portable noise-monitoring equipment for medical personnel, including noise monitor unit, and the surface-mounted integrated circuit being electrically connected with noise monitor unit；Surface-mounted integrated circuit is provided with battery case, on and off switch, alarm, mode control button, control valve and ann reset key；Noise monitor unit includes the rectification circuit being connected with surface-mounted integrated circuit, the audion T being connected with rectification circuit, the amplifier A being connected with audion T, and the noise probe L being connected with amplifier A.
Further, rectification circuit is full bridge rectifier.
Further, two inputs of full bridge rectifier are connected with surface-mounted integrated circuit；First outfan of full bridge rectifier is connected to the colelctor electrode of audion T, and one end of its second outfan and the first resistance R1 connects, and the other end of the first resistance R1 is connected to the emitter stage of audion T；The input of amplifier A is connected to noise probe L by the second electric capacity C2, and the outfan of amplifier A is connected to the base stage of audion T；The Vcc end of amplifier A is connected to the colelctor electrode of audion T by the second resistance R2, is connected to the Vee end of amplifier A by the first electric capacity C1；The Vee end of amplifier A is connected with the second outfan of full bridge rectifier.
Further, first input end and second input of full bridge rectifier is connected with surface-mounted integrated circuit respectively by electric connection line.
The beneficial effects of the utility model are: medical worker may utilize this noise level indicator and detects the noise in ICU, when the noise in range is higher than normal value, warning reminding can be carried out, to ensure that patient is in a health, the beneficially environment of rehabilitation.Additionally, noise monitor unit is by one two core cable transmission power supply and noise signal, circuit is simple and reliable；Having simple in construction, easy for installation, production cost is low, operates, controls, easy to use, stability advantages of higher.

Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand this utility model; it is to be understood that; this utility model is not limited to the scope of detailed description of the invention; from the point of view of those skilled in the art; as long as various changes limit and in the spirit and scope of the present utility model that determine, these changes are apparent from appended claim, all utilize innovation and creation that this utility model conceives all at the row of protection.
The portable noise-monitoring equipment for medical personnel as shown in Figure 1, including noise monitor unit, and the surface-mounted integrated circuit 3 being electrically connected with noise monitor unit.Surface-mounted integrated circuit 3 is provided with battery case 9, on and off switch 4, alarm 7, mode control button 6, control valve 5 and ann reset key 8.As in figure 2 it is shown, noise monitor unit includes the rectification circuit being connected with surface-mounted integrated circuit 3, the audion T being connected with rectification circuit, the amplifier A being connected with audion T, and the noise probe L being connected with amplifier A.
Wherein, as in figure 2 it is shown, above-mentioned rectification circuit is full bridge rectifier, two inputs of full bridge rectifier are connected with surface-mounted integrated circuit 3.First outfan of full bridge rectifier is connected to the colelctor electrode of audion T, and one end of its second outfan and the first resistance R1 connects, and the other end of the first resistance R1 is connected to the emitter stage of audion T；The input of amplifier A is connected to noise probe L by the second electric capacity C2, and the outfan of amplifier A is connected to transistor base；The Vcc end of amplifier A is connected to the colelctor electrode of audion T by the second resistance R2, is connected to the Vee end of amplifier A by the first electric capacity C1；The Vee end of amplifier A is connected with the second outfan of full bridge rectifier.The first input end of full bridge rectifier and the second input are connected with surface-mounted integrated circuit 3 respectively by electric connection line 2.
