Abstract
The utility model discloses an electrothermal constant temperature indirect laryngoscope, which comprises a mirror face and a handle. The utility model is characterized in that the linings of the mirror face and the handle are air cores, in which electric heating wires are arranged, and are connected with a switch and an indicating lamp which are arranged at the position of the handle. The electric heating wire is connected with an external power line through a switch. The utility model has the advantages that the heat production technique of the electric heating wire is used for the indirect laryngoscope which is heated by the external power and keeps the constant temperature; the use is convenient, and the cost of utilizing the electric heating wire to make heating is lower than that of utilizing the spirit lamp to make heating.
Description
This utility model relates to the diagnostic techniques in medical science, the hygiology, is a kind of with the chamber of visual examination human body or the instrument of pipe, specifically, is a kind of laryngoscope.
Laryngeal mirror is throat's routine examination apparatus of larynx section of hospital indispensability.Existing laryngeal mirror does not have electric heating device, has following shortcoming: the one, and the trouble of heating.Must heat to it with alcohol burner before use, and temperature control can only be grasped with feel.The 2nd, can not constant temperature.When room temperature was low, heat radiation comparatively fast in use must repeat to heat after the laryngeal mirror that process is heated left alcohol burner, and was pretty troublesome.
The purpose of this utility model provide a kind of with heating wire heat production technology be used for laryngeal mirror, heat and keep constant temperature, easy to use, than the electric heating constant temperature laryngeal mirror of heating with alcohol burner and more saving cost.
Technical solution of the present utility model is: a kind of electric heating constant temperature laryngeal mirror, comprise minute surface and handle, the difference of itself and prior art is: minute surface and handle inside for hollow, the hollow heating wire that is equipped with inside, and link with switch, the display lamp of handle part.
The utility model has the advantages that: improve at the prior art shortcoming, heating wire heat production technology is used for heating of laryngeal mirror and keeps constant temperature.It is a prerequisite with the optical texture that keeps existing laryngeal mirror, by external power supply, makes laryngeal mirror heat to 42 degree Celsius and keeps constant temperature, uses very conveniently, and heats than with alcohol burner with electricity heating and more to save cost.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the structural representation of a kind of electric heating constant temperature laryngeal mirror of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.Minute surface 1, handle 2, its optical texture of comprising existing laryngeal mirror among this embodiment keep, with being transformed into inside of minute surface 1 and handle 2 hollow after, put into the heating wire 3 of suitable specification, the switch 4, the display lamp 5 that make it and be contained in handle 2 rear portions link, by power line 6, plug 7 external power supplys, the minute surface 1 of laryngeal mirror is heated to 42 degree Celsius and maintenance constant temperature.
