Description

Medical catheter type electronic clinical thermometer

Technical field

This utility model relates to a kind of temperature measuring equipment, relates to a kind of Medical catheter type electronic clinical thermometer specifically.

Background technology

Though glass mercury clinical thermometer responds slowly, reading is inconvenient, easily broken, especially frangibility when child uses, poor and the hydrargyrum of safety to defects such as the pollutions that environment brings, but owing to not having better succedaneum for a long time, or relies on its cheap advantage and rules all the land.At present, along with the fast development of electronic technology, digital electronic clinical thermometer made even to this day, temperature-sensitive speed, degree of accuracy and digital display function have surmounted mercurial thermometer all widely.But, the various electronic clinical thermometers designed at present or because its price is too high, not easily sterilization and the factors such as volume is large and to be difficult to accept extensively by medical departments such as such as hospitals use.

Utility model content

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Medical catheter type electronic clinical thermometer, with solve existing electronic clinical thermometer price too high, not easily sterilization and the factors such as volume is large and be difficult to the problem accepted extensively by the medical departments such as such as hospital.

This clinical thermometer not only thermometric is accurate, and structure is simple, and cost of manufacture is low, and carries and use also very convenient.

To achieve these goals, the technical solution adopted in the utility model is: a kind of Medical catheter type electronic clinical thermometer, comprise display device, temperature sensor and connecting line, D/A converting circuit and control treatment circuit is provided with in described display device, be provided with digital display screen and socket on the display apparatus, its digital display screen is electrically connected with control treatment circuit by wire, and its socket is electrically connected with D/A converting circuit by wire; Described temperature sensor comprises the handle, insulation tube and the metal cap that connect successively, in metal cap, be provided with critesistor; One end of described connecting line is electrically connected with the critesistor in metal cap through handle and insulation tube, and its other end is equipped with the plug matched with socket, connecting line is electrically connected with the D/A converting circuit in display device by plug and socket.

Preferably, described display device is also provided with some compensating resistances, and the rotary switch of conversion compensating resistance, its compensating resistance is connected in the loop that critesistor and D/A converting circuit form, or is connected in parallel on the two ends of critesistor.

Further, described insulation tube is made up of food grade plastic.

Further, described metal cap is made up of rustless steel.

Adopt the utility model of the technical program, its beneficial effect is: clinical thermometer of the present utility model, because its temperature sensor adopts cheap brief material composition, be applicable to large-scale mass production, after temperature sensor is combined with display device, there is clear reading, safety easy to use, volume are little, reaction is fast, degree of accuracy advantages of higher, use middle temperature sensor interchangeable, reuse after can carrying out disinfecting of routine to temperature sensor, the complete alternative widely used mercurial thermometer in medical department at present of clinical thermometer of the present utility model.Certainly, the advantage that clinical thermometer of the present utility model is the most outstanding has stopped hydrargyrum evil.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Number in the figure: 1, display device; 2, temperature sensor; 3, connecting line; 4, plug; 11, digital display screen; 12, socket; 13, rotary switch; 21, hands handle; 22, insulation tube; 23, metal cap.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

See Fig. 1, Medical catheter type electronic clinical thermometer of the present utility model, comprise display device 1, temperature sensor 2 and connecting line 3, D/A converting circuit and control treatment circuit is provided with in described display device 1, display device 1 is provided with digital display screen 11 and socket 12, its digital display screen 11 is electrically connected with control treatment circuit by wire, and its socket 12 is electrically connected with D/A converting circuit by wire; Described temperature sensor 2 comprises the handle 21, insulation tube 22 and the metal cap 23 that connect successively, in metal cap 23, be provided with critesistor; One end of described connecting line 3 is electrically connected with the critesistor in metal cap 23 through handle 21 and insulation tube 22, its other end is equipped with the plug 4 matched with socket 12, connecting line 3 is electrically connected with the D/A converting circuit in display device 1 by plug 4 and socket 12.Described display device 1 is also provided with some compensating resistances, and the rotary switch 13 of conversion compensating resistance, its compensating resistance is connected in the loop that critesistor and D/A converting circuit form, or is connected in parallel on the two ends of critesistor.Described insulation tube 22 is made up of food grade plastic.Described metal cap 23 is made up of rustless steel.

Clinical thermometer of the present utility model, when actual fabrication, as long as record the resistance of each critesistor 37 DEG C time, when resistance be less than 30k Ω then compensating resistance be connected in the loop that critesistor and D/A converting circuit form; When resistance be greater than 30k Ω then compensating resistance be connected in parallel on the two ends of critesistor.Certainly, also can record the resistance of each critesistor when other temperature, the resistance of its resistance 30k Ω and compensating resistance is all comparatively speaking, and it does not specifically just repeat one by one at this.

Above are only a kind of embodiment of the present utility model, not in order to limit this utility model, all any amendments done within spirit of the present utility model and principle are equivalent to be replaced and improves, and all should be included within protection domain of the present utility model.
