Technical Field

[0001] The utility model relates to the field of ear canal temperature measuring devices, in particular to a disposable ear canal temperature probe. Background Art

[0002] Monitoring body temperature is an important part of clinical medical care work. The change of body temperature has very important clinical significance for clear diagnosis, judgment of the condition, and analysis of the curative effect. A disposable ear canal temperature probe consists of an instrument-end connecting plug, a signal transmission cable, a temperature probe, and a memory foam earplug. It is applicable to people in the emergency room, operating room, special care for infants, or pediatrics who need continuous body temperature measurement.

[0003] An ear canal temperature probe disclosed in Chinese Utility Model (Publication No.: CN203736169U) includes a temperature measuring end head, in which a temperature sensing chip, a connecting wire, and a whole piece of ear canal memory foam are provided. The temperature sensing chip is assembled at the top of the whole piece of ear canal memory foam, and the temperature sensing chip is connected to a plug terminal through the connecting wire. When in use, pinch the ear canal memory foam and place it in the ear canal. As time goes by, it will slowly restore its shape and fill the sealed ear canal, isolating the influence of the outside air of the ear canal, improving the existing device in which the temperature sensing memory foam and the isolation foam are separated, and the connecting wire is thin and requires cumbersome processes such as a sheath handle, thereby simplifying the cost.

[0004] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology. During the continuous body temperature measurement process, the temperature probe is always in the patient's ear canal, and the above device is not provided with a limiting device for inserting the temperature probe into the ear canal. Especially for child patients, due to their resistant psychology and active nature, it is easy for the temperature probe to be inserted too deep into the ear canal, causing damage to the ear canal. Therefore, a disposable ear canal temperature probe is now proposed. Content of the Utility Model

[0005] In order to improve the problem that the existing ear canal temperature probe is not provided with a limiting device for inserting the temperature probe into the ear canal. Especially for child patients, due to their resistant psychology and active nature, it is easy for the temperature probe to be inserted too deep into the ear canal, causing damage to the ear canal, the present utility model provides a disposable ear canal temperature probe.

[0016] By adopting the above technical solution, the setting of the scale bar facilitates the user to observe the depth of the device inserted into the ear canal.

[0017] Optionally, an elastic ring is fixedly connected to the end face of the second memory foam away from the first memory foam.

[0018] By adopting the above technical solution, after inserting the first memory sponge and the second memory sponge into the inner ear canal, an elastic ring is sleeved on the ear, and it is not easy for the device to fall out from the inner part of the ear canal.

[0019] Optionally, a silica gel sleeve is installed on the surface of the catheter near one end of the instrument connection plug.

[0031] The following will further elaborate on this application in conjunction with the attached Figures 1-3 drawings.

[0032] Please refer to Figure 1 , a disposable ear canal body temperature probe, including a catheter 1, an instrument connection plug 2 installed at one end of the catheter 1, and an NTC temperature chip 3 installed at the other end of the catheter 1. A silicone sleeve 13 is installed on the surface of the catheter 1 near the instrument connection plug 2. The setting of the silicone sleeve 13 facilitates the user to hold the entire device.

[0033] Refer to Figures 1-3 , a transmission line 4 is installed between the NTC temperature chip 3 and the instrument connection plug 2. The transmission line 4 is located inside the catheter 1. A first memory foam 5 is installed on the surface of the catheter 1 at the end where the NTC temperature chip 3 is located. The top of the first memory foam 5 is set as a hemispherical structure. This kind of structure setting facilitates the insertion of the first memory foam 5 into the patient's ear canal. A plurality of connection branches 14 are fixedly connected to the periphery of the catheter 1 at one end inside the first memory foam 5, and the plurality of connection branches 14 are distributed in a circular array inside the first memory foam 5. The setting of the connection branches 14 improves the connection effect between the catheter 1 and the first memory foam 5. Therefore, when the first memory foam 5 is taken out of the ear canal, it is not easy for the first memory foam 5 to fall off in the ear canal, improving the use safety. A second memory foam 6 is installed on the surface of the catheter 1 on one side of the first memory foam 5. A scale bar 11 is arranged on the surface of the second memory foam 6. The setting of the scale bar 11 facilitates the user to observe the depth of the device inserted into the ear canal. The NTC temperature chip 3 is located between the first memory foam 5 and the second memory foam 6. By inserting the first memory foam 5 and the second memory foam 6 into the ear canal, the NTC temperature chip 3 located in the first memory foam 5 and the second memory foam 6 measures the temperature in the ear canal. While reducing the damage to the ear canal, it can block the influence of the surrounding air environment on the temperature measurement accuracy and accurately detect the core body temperature. An elastic ring 12 is fixedly connected to the end face of the second memory foam 6 away from the first memory foam 5. After the first memory foam 5 and the second memory foam 6 are inserted into the ear canal, the elastic ring 12 is sleeved on the ear, making it not easy for the device to fall out of the ear canal.

A screw tube 8 is threadedly connected to the surface of the threaded section 7. A limiting ring plate 9 is fixedly connected to the surface of one end of the screw tube 8. After inserting the first memory sponge 5 and the second memory sponge 6 into the ear canal, by rotating the screw tube 8, the limiting ring plate 9 is driven to move horizontally. When the limiting ring plate 9 fits against the ear, stop rotating, so as to effectively limit the device from being inserted too deep into the ear canal due to external force, reducing the damage to the ear canal. Anti-slip lines 10 are provided on the surface of the screw tube 8, and the anti-slip lines 10 facilitate the rotation of the screw tube 8.

[0035] The implementation principle of the present utility model is as follows: When in use, by inserting the first memory sponge 5 and the second memory sponge 6 into the ear canal, the NTC temperature chips 3 located in the first memory sponge 5 and the second memory sponge 6 measure the temperature in the ear canal. At this time, the elastic ring 12 is sleeved on the ear, which is not easy to make the device fall out of the ear canal. Moreover, a scale bar 11 is provided on the surface of the second memory sponge 6, and the scale bar 11 facilitates the user to observe the depth of insertion of the device into the ear canal. At the same time, by rotating the screw tube 8, the limiting ring plate 9 is driven to move horizontally. When the limiting ring plate 9 fits against the ear, stop rotating, so as to effectively limit the device from being inserted too deep into the ear canal due to external force, reducing the damage to the ear canal; Finally, the connection branch 14 improves the connection effect between the catheter 1 and the first memory sponge 5, so that when the first memory sponge 5 is taken out of the ear canal, it is not easy for the first memory sponge 5 to fall off in the ear canal, improving the use safety.

[0036] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
