Abstract
This utility model patent discloses a kind of lens of laparoscope heater, comprise epitheca (1), inner bag (2), temperature detect switch (TDS) (3), 36V power supply (4) and resistive heater (5), it is characterized in that, the U-shaped tubular structure that described inner bag (2) is made for aluminium alloy, outside is coated with the epitheca (1) that one deck plastics are made, resistive heater (5) is equipped with in the inside of described inner bag (2), and described resistive heater (5) is connected with described 36V power supply (4) by a described temperature detect switch (TDS) (3).This utility model is by the heating of metal inner tube, plastics epitheca and the resistive heater that controlled by temperature detect switch (TDS), insulation effect, make lens of laparoscope can be heated rapidly to 50 DEG C and good insulation, heating is quick and don't cause patient to scald, and facilitates medical personnel to clamp and operate.
Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of lens of laparoscope heater.
Background technology
The general diameter 10mm of lens of laparoscope used in abdominal operation, just can put into abdominal cavity, play anti-fog function, and lens of laparoscope heater mainly plays a part lens of laparoscope to be heated to about 50 DEG C after heating.
, there is the shortcomings such as anti-fog effect is bad, use is inconvenient, heat insulation effect is not good, need to improve in the methods such as the antifog employing spray-proof oil of lens of laparoscope in the past, povidone iodine wiping or hot-water soak.
Summary of the invention
Goal of the invention: in order to overcome the defect of prior art, a kind of lens of laparoscope heater of ad hoc meter, reach heating fast, high insulating effect, the object such as easy to operate.
Technical scheme: a kind of lens of laparoscope heater, comprises epitheca 1, inner bag 2, temperature detect switch (TDS) 3,36V power supply 4 and resistive heater 5, the U-shaped tubular structure that described inner bag 2 is made for aluminium alloy, and outside is coated with the epitheca 1 that one deck plastics are made; Resistive heater 5 is equipped with in the inside of described inner bag 2, and described resistive heater 5 is connected with described 36V power supply 4 by a temperature detect switch (TDS) 3;
The closing temperature of described temperature detect switch (TDS) 3 is set as 70 DEG C, and after namely resistive heater 5 and inner bag 2 are heated to 70 DEG C, described temperature detect switch (TDS) 3 cuts out voluntarily;
Described epitheca 1 also scribbles heat-insulation layer, can power consumption be reduced, keep heater body to maintain 70 DEG C, and the also convenient gripping of plastics epitheca;
Described inner bag 2 also offers the micropore that some diameters are 2mm, is convenient to externally carry out conduction of heat;
The internal diameter of the open at one end of described inner bag 2 is consistent with the diameter of lens of laparoscope 6, is heated by resistive heater 5 and inner bag 2 pairs of lens of laparoscopes 6 and is incubated.
The beneficial effects of the utility model: this utility model is by the heating of metal inner tube, plastics epitheca and the resistive heater that controlled by temperature detect switch (TDS), insulation effect, make lens of laparoscope can be heated rapidly to 50 DEG C and good insulation, heating is quick and don't cause patient to scald, and facilitates medical personnel to clamp and operate.
Accompanying drawing explanation
Fig. 1 is that this utility model lens of laparoscope heater uses schematic diagram (containing lens of laparoscope).
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1, a kind of lens of laparoscope heater, comprises epitheca 1, inner bag 2, temperature detect switch (TDS) 3,36V power supply 4 and resistive heater 5, the U-shaped tubular structure that described inner bag 2 is made for aluminium alloy, and outside is coated with the epitheca 1 that one deck plastics are made; Resistive heater 5 is equipped with in the inside of described inner bag 2, and described resistive heater 5 is connected with described 36V power supply 4 by a temperature detect switch (TDS) 3;
The closing temperature of described temperature detect switch (TDS) 3 is set as 70 DEG C, and after namely resistive heater 5 and inner bag 2 are heated to 70 DEG C, described temperature detect switch (TDS) 3 cuts out voluntarily;
Described epitheca 1 also scribbles heat-insulation layer, can power consumption be reduced, keep heater body to maintain 70 DEG C, and the also convenient gripping of plastics epitheca;
Described inner bag 2 also offers the micropore that some diameters are 2mm, is convenient to externally carry out conduction of heat;
The internal diameter of the open at one end of described inner bag 2 is consistent with the diameter of lens of laparoscope 6, is 10mm; Heat by resistive heater 5 and inner bag 2 pairs of lens of laparoscopes 6 and be incubated.
The foregoing is only preferred embodiments of the present utility model, not in order to limit this utility model, any amendment done within spirit of the present utility model and principle, equivalent replacement, improvement etc., all should be included within system structure of the present utility model.
