Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stethoscopes, in particular to a constant temperature stethoscope. Background Art
[0002] The stethoscope is one of the commonly used diagnostic tools in the medical field. It can help doctors understand the condition of the patient's heart, lungs and other organs. However, the temperature of existing stethoscopes will change due to changes in the external ambient temperature. Especially in the autumn and winter seasons, because the outside temperature is too low, it is common for the stethoscope to drop to more than ten degrees or even several degrees or below zero (outdoor diagnosis). The human body temperature is about 37°C. The large temperature difference between the stethoscope and the human body will cause a strong short-term stimulation to the human body, causing the human blood vessels to contract instantly and the heartbeat to accelerate. At the same time, the low temperature stimulation will also cause the intensity and frequency of a person's breathing to change. As a result of the above changes, the result of the stethoscope will cause a certain deviation from the actual situation, which will have an adverse effect on the doctor's judgment of the condition. The stethoscope thermostat box involved in the utility model will create a local constant temperature environment, so that the temperature of the stethoscope placed therein is consistent with or slightly higher than the human body temperature, so as to avoid the stimulation of the heartbeat and breathing of the human body due to the stethoscope being too low in temperature, and ensure the accuracy of the diagnosis result. Chinese utility model patent application number CN206534708U discloses a stethoscope thermostat. The thermostat consists of six components: a temperature sensor probe, a controller, an electric heater, a housing, a battery, and a power supply. The stethoscope housing has a two-layer structure: an upper layer houses the stethoscope, where the temperature sensor probe is mounted; and a lower layer houses the electronic components, where the controller, electric heater, and battery are mounted. The temperature sensor senses the temperature of the upper layer and transmits this data to the controller, which serves as the core of the thermostat. The controller, based on the temperature data from the temperature sensor, decides whether to power on or off the electric heater. The advantage of this thermostat is that it maintains an environment at or above 37°C (human body temperature), keeping the stethoscope's temperature at or slightly above human body temperature. This prevents the stethoscope from stimulating the heart and breathing during autumn and winter, which can be caused by the stethoscope's own low temperature.
