Abstract
The utility model discloses a special scraper for dermatology and belongs to dermatological inspection tools. The special scraper comprises a scraper handle and a scraper body, wherein an electric heating wire and a temperature sensor are arranged on the scraper body; a power supply and a controller are arranged in the scraper handle; a switch and a temperature alarm lamp are arranged at the tail of the scraper handle; the switch is provided with a first normally open contact and a second normally open contact; the controller comprises a time relay, a comparator and a triode; the power supply is sequentially connected with the electric heating wire through the first normally open contact of the switch and a normally closed contact of the time relay in sequence; the second normally open contact of the switch controls energization and deenergization of a coil of the time relay. According to the special scraper, the scraper body is sterilized at high temperature in an electric heating mode, the sterilization time is controlled by the time relay, the work of medical staff is facilitated, and the sterilization effect of the scraper body is ensured.
Description
Technical field
This utility model relates to a kind of dermatological special scraper, belongs to the department of dermatologry instruments of inspection.
Background technology
At present, dermatologist is carrying out before scraping patient skin with scraper, need to cutter hub, carry out high-temperature sterilization with alcohol burner, in disinfecting process, doctor need to hold scraper always and rock back and forth on alcohol burner, and disinfecting time is also to estimate according to doctor's experience.After sterilization, doctor can pass through the body surface multiple-contact cutter hub of oneself, and in the cooling rear ability of confirmation cutter hub, patient is carried out to scraping.Such disinfecting process is not only wasted time and energy, and Disinfection Effect is also undesirable.
Utility model content
This utility model, for the problem in background technology, proposes a kind of dermatological special scraper.
This utility model, for overcoming the above problems, adopts following technical scheme:
A dermatological special scraper, comprises handle of a knife and cutter hub; Described cutter hub is provided with heating wire and temperature sensor; In described handle of a knife, be provided with power supply and controller; Described handle of a knife afterbody is provided with a switch and a temperature alarming lamp; Described switch has the first normally opened contact and the second normally opened contact; Described controller comprises the time relay, comparator and audion; Described power supply is connected with heating wire by the first normally opened contact of switch and the normally-closed contact of the time relay successively; The second normally opened contact of described switch is controlled the coil power on/off of the time relay; An input of described comparator is connected with temperature sensor, and another input is connected with reference voltage; The output signal of described comparator is controlled temperature alarming lamp by audion and is worked.
Preferably, described power acquisition lithium battery.
Technique effect:
1, this utility model carries out high-temperature sterilization by electrically heated mode to cutter hub, and disinfecting time is controlled by the time relay, has not only facilitated medical worker's work, but also has guaranteed the Disinfection Effect of cutter hub.
2,, during cutter hub excess Temperature, temperature alarming lamp can be reminded medical worker, to avoid scalding patient skin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit structure block diagram of the present utility model.
Label title in Fig. 1: 1, handle of a knife; 2, cutter hub; 3, heating wire; 4, temperature sensor; 5, power supply; 6, controller; 7, switch; 8, temperature alarming lamp.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, comprises handle of a knife 1 and cutter hub 2; Described cutter hub 2 is provided with heating wire 3 and temperature sensor 4; In described handle of a knife 1, be provided with power supply 5 and controller 6; Described handle of a knife 1 afterbody is provided with a switch 7 and a temperature alarming lamp 8; Described switch 7 has the first normally opened contact and the second normally opened contact; Described controller 6 comprises the time relay, comparator and audion.
As shown in Figure 2, described power supply 5 is connected with heating wire 3 by the first normally opened contact of switch 7 and the normally-closed contact of the time relay circuit structure of the present utility model successively; The second normally opened contact of described switch 7 is controlled the coil power on/off of the time relay; An input of described comparator is connected with temperature sensor 4, and another input is connected with reference voltage; The output signal of described comparator is controlled 8 work of temperature alarming lamp by audion.
Described power supply 5 adopts lithium battery; Described comparator adopts the LM339 of PHILIPS Co.; Described temperature alarming lamp 8 adopts red LED lamp; The described time relay adopts the small-sized closed type time relay; Described handle of a knife 1 adopts heat-barrier material to make, and its inside is provided with cavity; Described temperature sensor 4 adopts the temperature sensor of analog output; Described reference voltage forms by electric resistance partial pressure, and the temperature value that reference voltage is corresponding is alarm temperature value.
In the time of need to sterilizing, only need press switch 7, the first normally opened contact meeting conducting of switch 7, heating wire 3 can be switched on and cutter hub 2 be carried out to heating disinfection, meanwhile, the also conducting of the second normally opened contact of switch 7, the coil of the time relay can be switched on and be started timing, when the time of advent relay setting-up time time (this time is the time of cutter hub heating disinfection), the normally-closed contact of the time relay can disconnect, and now, the power supply of heating wire 3 is cut off, heating wire 3 stops heating, and completes sterilization.After sterilization, doctor can judge that whether cutter hub 2 is cooling by temperature alarming lamp 8, concrete principle is as follows, comparator compares temperature signal and the reference voltage of temperature sensor output: when the temperature value detecting when temperature sensor is greater than temperature value corresponding to reference voltage, the output signal of comparator can be lighted temperature alarming lamp 8 by audion, higher to represent cutter hub 2 temperature, can not use; When the temperature value detecting when temperature sensor is less than temperature value corresponding to reference voltage, the output signal of comparator can be extinguished temperature alarming lamp 8 by audion, lower to represent cutter hub 2 temperature, can use.
