Medical portable stethoscope constant temperature heating device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a medical portable stethoscope constant-temperature heating device.

Background

Stethoscopes are the most commonly used diagnostic tools for doctors. Stethoscope has been improved in shape and sound transmission mode since it is applied to clinic, but its basic structure is not changed much. When the stethoscope head made of metal is lower than the body temperature at room temperature, the patient feels uncomfortable when the stethoscope head contacts with the patient, and conditional reflex, such as heart beat acceleration and other symptoms, can be caused, so that the diagnosis is inaccurate.

At present, there is a certain research progress in heating stethoscopes both domestically and abroad. On one hand, people solve the problem of cooling the stethoscope head by changing the material of the stethoscope head, such as adding an anti-cooling ring on the stethoscope head, but the lifting temperature of the device is limited; on the other hand, the heating device of the stethoscope is related to, the heating material is used for directly transferring heat, and the circuit with the heating material is electrified to achieve the purpose of heating the stethoscope, the device can be made into a heating sleeve which is directly fixed on the stethoscope head, the heating sleeve is internally sealed with heat conducting liquid, and the heating wire is positioned in the heat conducting liquid, but the materials of the heat conducting liquid and the heating wire can have a certain influence on the use effect of the stethoscope, and the heating sleeve is further improved to reduce the listening effect of the stethoscope; the heating material can be made into a portable or fixed heating device, the heating material is made into an inner core of the device, heat is generated after current is conducted, the heating material is directly contacted with the stethoscope to achieve the heating purpose, and the heating material can be covered by the heat insulation material to reduce the loss of heat, but the device is inconvenient to carry, has low safety, is complex in use method and is not popularized and used clinically. At present, a constant temperature circuit is also used for controlling the heating device of the type to keep the constant temperature of the stethoscope head, and the constant temperature is mainly controlled by a controller, a temperature sensor and a thermal switch.

The heating of the stethoscope head is also accomplished by adopting the principle of radio induction heating through a wireless transmitting circuit module, a transmitting coil, a receiving coil, a load resistor and the like. The wireless transmitting circuit module converts electric energy provided by the direct-current power supply into alternating-current signals and sends the alternating-current signals to the transmitting coil; electromagnetic waves emitted by the transmitting coil are received by a receiving coil of the stethoscope head, and the receiving coil transmits the received electric energy to a load resistor. The receiving coil and the load resistor radiate heat at the stethoscope head, so that the temperature of the stethoscope head is increased. But the device is complicated in manufacturing process and high in cost.

The stethoscope heating device needs to solve the defects of constant temperature control, portability, high cost and the like at present.
