Abstract

The utility model relates to a medical timer, which comprises a shell, wherein a plurality of groups of timing circuits are installed in the shell; in each timing circuit, a reset module, a clock module and a key module are connected with the input end of a central processor, a first LED display module, a second LED display module, a first LED flashing module and a second LED flashing module are connected with the output end of the central processor, and a power supply module supplies power for each module. In the medical timer provided by the utility mode, a time is set, such as 20 minutes, then a start key is pressed for countdown, and after the time is up, the time displayed by the display modules is 00:00, and the LED flashing modules flash to remind medical personnel to examine and handle in time to avoid missing the consultation hours.

Description

Medical timer

Technical field

The utility model relates to a kind of timer, particularly a kind of medical timer of determining medical treatment or Diagnostic Time by countdown.

Background technology

At present; medical personnel are in some need diagnosis or treatment means than precise time; mostly be to adopt the method for seeing clock; for example rapid pulse is fought or is determined time of skin test; particularly the time of skin test determines; help medical personnel to avoid occurring the malpractice that causes because of irritated, guarantee patient's safety.But when the patient was more, medical personnel were easy to miss the best time, thereby can only do skin test once more, have increased patient's misery.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of medical timer, can set a countdown time at a plurality of patients easily, and after the time expired, the prompting medical personnel in time checked and dispose.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of medical timer, comprise housing, and circuit is installed in the housing during many batch totals; In the described timing circuit, reseting module, clock module and key-press module are connected with the input end of central processing unit, the one LED display module, the 2nd LED display module, LED flicker module are connected with the output terminal of central processing unit with the 2nd LED flicker module, and power module is above each module for power supply.

Described central processing unit is AT89S51.

Described key-press module is divided into two groups, and every group has initiating key, Pause key and reset key.

The surface area of described initiating key top end face greater than Pause key or reset key top end face surface area.

Described LED flicker module is near a LED display module, and the 2nd LED flicker module is near the 2nd LED display module.

Also be provided with a plurality of clips on the described housing.

The output terminal of described central processing unit also is connected with buzzer circuit.

A kind of medical timer that the utility model provides, by setting a time, for example 20 minutes, press countdown behind the initiating key then, after time expired, the LED display module demonstration time was 00:00, the flicker of LED flicker module, thereby the prompting medical personnel in time check and dispose, avoid missing consultation hours.

In timing circuit, adopted cheap AT89S51 scheme, utilize two groups of Timer in it directly to drive two groups of LED display modules, saved production cost.8 remaining IO mouths connect 6 buttons and 2 groups of LED flicker modules respectively, have made full use of the resource of AT89S51.

Fig. 2 is a logic diagram of circuit of the present utility model.

Fig. 3 is a circuit block diagram of the present utility model.

Embodiment

In Fig. 2, Fig. 3, a kind of medical timer comprises housing 1, and circuit is installed in the housing 1 during many batch totals; By the stack of timing circuit, can realize more timing.

In the described timing circuit, reseting module, clock module and key-press module are connected with the input end of central processing unit, the one LED display module, the 2nd LED display module, LED flicker module are connected with the output terminal of central processing unit with the 2nd LED flicker module, and power module is above each module for power supply.

Described central processing unit is AT89S51.

Described key-press module is divided into two groups, and every group has initiating key 4, Pause key 5 and reset key 6.

The surface area of described initiating key 4 top end faces greater than Pause key 5 or reset key 6 top end faces surface area.Thereby be convenient to operating personnel's difference in operation.

Also be provided with a plurality of clips 7 on the described housing 1.

Embodiment: in Fig. 1, circuit when in the housing 1 three batch totals being installed, be respectively equipped with 6 LED display modules 3, side at LED display module 3 is provided with initiating key 4, Pause key 5 and reset key 6, the surface area of initiating key 4 top end faces is greater than the surface area of Pause key 5 or reset key 6 top end faces, be convenient to distinguish when the paramedic operates, reduce maloperation, press Pause key 5 and can suspend countdown, press 6 present timing of reset key and restart from the time of setting, by software setting, length was pressed initiating key after 4 five seconds, enter the pattern of setting, can regulate the countdown time with Pause key 5 and reset key 6.Circuit was public when reset button was three batch totals, was installed in housing 1 side, was used for making central processing unit to reset.

Circuit connects respectively during every batch total, two groups of LED display modules 3, for example a LED display module and the 2nd LED display module, be operating as example with skin test, after medical personnel finish the skin test injection, patient's disposal singly is clipped near on the clip 7 of LED display module 3 one sides, can makes the patient corresponding one by one like this with LED display module 3.

Press initiating key 4, after the central processing unit received signal, the 3 beginning countdowns of driving LED display module, clock module is used for providing the reference clock of needs to central processing unit, after reaching the time of setting, central processing unit driving LED flashing lamp 2 begins flicker, and until pressing reset key 6, LED display module 3 is replied initial preset state simultaneously.

In timing circuit, made full use of the resource of AT89S51 central processing unit, saved production cost.Integrated two groups of Timer in the AT89S51 central processing unit, a LED display module all is to separate control by different Timer with LED flicker module with the 2nd LED display module and the 2nd LED flicker module, is independent of each other.32 integrated IO mouths, wherein 24 directly drive two groups LED display module 3 with scan pattern, and 8 remaining IO mouths connect six press keys and two groups of LED flicker modules respectively, have made full use of the resource of AT89S51 central processing unit.

Consider that hospital needs relatively quietly environment, the utility model does not recommend to be provided with hummer, but as the scheme of optimizing, being used in the one LED display module and the 2nd LED display module can be shown the shared IO mouth of data line of " point " or do not use the IO mouth, because " point " in a LED display module and the 2nd LED display module can be normal bright or the fixed frequency flicker, for example 1 second, can save 1-2 IO mouth like this, be used to connect buzzer circuit, the pulsed drive buzzer call of output characteristic frequency, because the directive property of hummer is not high, so circuit only needs to connect a hummer and gets final product during the many batch totals in the utility model.
