[0002] In respiratory therapy equipment, the dew point temperature at the patient end is a crucial parameter for humidifiers, directly impacting treatment effectiveness and patient comfort. Dew point temperature is determined by both temperature and humidity (hereinafter referred to as temperature and humidity), making accurate measurement crucial. To achieve this, temperature and humidity probes are widely used in respiratory therapy equipment.

[0003] Conventional temperature and humidity probes typically incorporate a cylindrical thermistor mounted on the outside of the probe body. As air flows through the probe, the leeward side of the thermistor faces away from the airflow, preventing it from making direct contact. This can lead to inaccurate temperature measurements.

[0029] Please refer to Figures 1 to 4The first embodiment of the present application provides a temperature and humidity probe 10 for use in respiratory therapy equipment, wherein the temperature and humidity probe includes a negative temperature coefficient thermistor 1211 and a humidity sensor 1231; first, the temperature and humidity probe 10 is set in the respiratory therapy equipment to ensure that the gas can evenly contact the temperature and humidity probe 10; when the air flows through, the windward head 1212 of the negative temperature coefficient thermistor 1211 faces the direction of the airflow, and the windward head 1212 adopts a teardrop-shaped or spherical structure to minimize turbulence and airflow interference, ensuring that the negative temperature coefficient thermistor 1211 is heated evenly and improving the temperature measurement accuracy. At the same time, the humidity sensor 1231 is set in the drainage groove 124 to avoid measurement interference caused by water vapor accumulation and prevent condensed water from adhering to the humidity sensor 1231 for a long time, affecting the test accuracy. The humidity sensor 1231 monitors the humidity changes in the surrounding environment in real time and can quickly respond to humidity fluctuations. In order to effectively handle condensed water, a first water drop slope 122 is provided under the negative temperature coefficient thermistor 1211. The first water drop slope 122 is used to guide the condensed water to flow out along a preset path to prevent moisture from accumulating around the negative temperature coefficient thermistor 1211, thereby maintaining the accuracy of temperature measurement. The humidity sensor 1231 is provided with a second water drop slope 1241. The second water drop slope 1241 is used to guide the condensed water to flow out along a preset path to prevent moisture from accumulating around the humidity sensor 1231, thereby maintaining the accuracy of humidity measurement. The humidity sensor 1231 can be set as a device such as a humidity resistor or a humidity capacitor to detect the humidity of the airflow separately. The humidity sensor 1231 can also be set as an existing temperature and humidity sensor, that is, a temperature and humidity sensor can simultaneously detect the humidity and temperature of the airflow, but only uses the humidity detection data of the temperature and humidity sensor, and does not use inaccurate temperature detection data. The temperature data detected by the negative temperature coefficient thermistor 1211 is combined with the humidity data detected by the temperature and humidity sensor 1231 to achieve accurate measurement of the airflow humidity and airflow temperature. Finally, the temperature and humidity probe 10 converts the signal of the temperature and humidity sensor 1231 into readable data through the built-in signal processing circuit, and connects to the respiratory therapy equipment through the interface to display and monitor the dew point temperature and humidity parameters at the patient end in real time.

[0031] Please refer to Figure 2 In some embodiments, the windward head 1212 is in a teardrop shape or a spherical shape, which can minimize turbulence and airflow interference in the airflow.

The fixing handle 1213 extends from the fixing groove 1214 and is arranged perpendicular to the bottom of the groove, thereby providing better structural stability and airflow guidance, not only reducing the error caused by vibration and airflow fluctuations, but also ensuring the long-term stability of the negative temperature coefficient thermistor 1211 in high temperature and high humidity environments, thereby extending the service life of the equipment.

[0033] Please refer to Figures 1 to 2 In some embodiments, a first water drop slope 122 is further provided at the top of the support member 12, and the first fixing column 121 is provided on the first water drop slope 122. The first water drop slope 122 is used to guide the condensed water condensed on the windward head 1212, thereby preventing the condensed water from accumulating on the windward head 1212, ensuring that the condensed water does not affect the measurement of the negative temperature coefficient thermistor 1211, thereby improving the accuracy and reliability of the temperature measurement.

[0034] Please refer to Figure 2 In some embodiments, an arc-shaped transition section 1221 is provided at the connection between the first fixed column 121 and the first water drop slope 122.

[0038] Please refer to Figures 3 and 4 In some embodiments, the lower side wall of the drainage groove 124 extends outward with a second water drop slope 1241, and the second water drop slope 1241 is used to guide the condensed water condensed in the drainage groove 124, thereby ensuring that the condensed water in the drainage groove 124 can be quickly discharged, further optimizing the drainage efficiency, reducing the risk of the humidity sensor 1231 being submerged by condensed water, reducing the failure rate, and extending the service life of the humidity sensor 1231.

[0039] Please refer to Figures 1 to 2In some embodiments, the base body 11 and the support member 12 are made of biocompatible materials such as silicone, polyurethane, and polypropylene, thereby increasing the biosafety and reliability of the temperature and humidity probe and preventing the patient's cardiopulmonary function from being damaged during use.

[0040] Please refer to Figures 1 to 2 In some embodiments, a gap is left between the first fixing column 121 and the second fixing column 123, so that the airflow can flow smoothly through the windward head 1212, so that the windward head 1212 is evenly heated, ensuring that the negative temperature coefficient thermistor 1211 is evenly heated, avoiding the problem of inaccurate temperature measurement caused by the traditional probe because the leeward side cannot directly contact the airflow, providing more reliable temperature data and providing an accurate basis for patient treatment.

[0041] In some embodiments, the second embodiment of the present application provides a respiratory therapy device, which includes the temperature and humidity probe as described above, thereby improving the accuracy and stability of temperature and humidity measurements of the respiratory therapy device. Since the temperature and humidity data are more accurate, medical personnel can adjust personalized treatment plans based on more accurate parameters, thereby optimizing the overall medical effect.
