Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to an ear cavity temperature probe. BACKGROUND

[0002] Body temperature is an external reaction of human health, and most of the ways to check body temperature are not isolated from the external environment. The detection device is in communication with the air outside, which leads to inaccurate detection results. The closed ear temperature measurement probe can more accurately measure body temperature.

[0003] The existing closed ear temperature measurement probe cannot contact the ear canal. The closer it is to the eardrum, the closer the measurement result is to the core temperature. When the probe contacts the eardrum, there is a risk of damaging the eardrum, reducing the user's experience. CONTENT OF THE INVENTION

[0004] The ear cavity temperature probe provided by the present application solves the problem of the risk of damaging the eardrum when measuring body temperature with a closed ear temperature measurement probe.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] An ear cavity temperature probe, comprising: a flexible earplug body comprising opposite top and tail ends;

[0007] A temperature sensor is a cylindrical structure, the temperature sensor is fixed to the side surface below the top end of the earplug body, and the temperature sensor and the surface of the earplug body are arc transitioned, and

[0008] A signal transmission component is signal interconnected with the temperature sensor to obtain temperature data collected by the temperature sensor.

[0009] By adopting the above technical scheme, the temperature sensor is fixed to the side surface below the top end of the earplug body. When using the ear cavity temperature probe, the temperature sensor can directly contact the skin of the ear canal when the flexible earplug expands, so as to measure the body temperature without contacting the eardrum. At the same time, the temperature sensor and the surface of the earplug body are arc transitioned, which can avoid scratching the ear canal by the temperature sensor, and the signal transmission of the temperature sensor can be wired transmission.

[0010] In one embodiment, the signal transmission component is a signal transmission line, which is embedded into the earplug body from the tail end of the earplug body to electrically connect with the temperature sensor.

[0011] By adopting the above technical scheme, the ear cavity temperature probe is suitable for wired signal transmission.

[0012] In one of the embodiments, the signal transmission line is two, respectively connected with the positive and negative of the temperature sensor, the signal transmission line includes a wire and an insulation layer covering the wire, wherein the cross-sectional area of the wire is less than 30 AWG.

[0013] By adopting the above technical scheme, the cross-sectional area of the wire is reduced, the wire is prevented from neutralizing with the external environment temperature, the measurement result is affected, and the measurement of the ear cavity temperature probe is more accurate.

[0014] In one of the embodiments, the part of the signal transmission line embedded in the earplug body is sleeved with a stiffening pipe, and the stiffening pipe protrudes from the earplug body by not less than 2 mm.

[0015] By adopting the above technical scheme, the ear cavity temperature probe can be more conveniently inserted into the ear cavity, and the stiffening pipe can be used as a handle to drive the earplug body to be inserted into the ear cavity.

[0016] In one of the embodiments, a limiting rib is arranged outside the stiffening pipe.

[0017] By adopting the above technical scheme, the friction between the stiffening pipe and the earplug is increased, when the ear cavity temperature probe is inserted into the ear cavity, the ear cavity temperature probe can be inserted into the ear cavity by rotating the stiffening pipe.

[0018] In one of the embodiments, a scale is marked on the surface of the flexible earplug body.

[0019] By adopting the above technical scheme, the doctor can predict the depth of the ear cavity temperature probe inserted into the ear canal according to the marked scale, and avoid inserting too deep to damage the eardrum.

[0020] In one of the embodiments, the earplug body includes an insertion section and an ear outer section, the insertion section is conical, and the ear outer section is connected with the insertion section in a necked shape.

[0021] By adopting the above technical scheme, the insertion section is conical, the resistance of the flexible earplug body inserted into the ear canal is reduced, and the necked part is convenient for fingers to pinch the flexible earplug body.

[0022] In one of the embodiments, the insertion section includes a measurement section and a transition section arranged at intervals, the temperature sensor is arranged in the measurement section, and the interval between the measurement section and the transition section is not greater than 2 mm.

[0023] By adopting the above technical scheme, an air layer is left in the middle of the flexible earplug body, the external environment temperature is prevented from being conducted through the flexible earplug body, and meanwhile, the section inserted into the ear is ensured not to be affected by the interval.

[0024] In one of the embodiments, the signal transmission part controls a chip, and the chip is wirelessly connected with the temperature sensor.

[0025] By using the above technical solution, the ear cavity temperature probe is suitable for wireless signal transmission.

[0026] In one of the embodiments, the flexible earplug body is provided with a disposable protective film, and the protective film exposes the temperature sensor.

[0027] By using the above technical solution, the ear canal is not cleaned to avoid pollution of the flexible earplug body.

[0028] In summary, the present application has at least one of the following beneficial technical effects:

[0029] 1. By setting the exposed part of the temperature sensor at the lower side of the top end of the flexible earplug body, and making the exposed part of the temperature sensor flush with the surface of the flexible earplug body, the temperature sensor can be prevented from directly contacting the eardrum and damaging the eardrum, and the temperature sensor can be prevented from scratching the ear canal when it is inserted into the ear canal.

[0030] 2. By dividing the flexible earplug body into two sections of an insertion end and an ear outer section, and connecting them in a necked shape, an air layer is left between the flexible earplug body, the external temperature is conducted to the air layer through the ear outer section, and the insertion section further insulates the external temperature, thereby reducing the conduction of the flexible earplug body to the temperature in the ear cavity and improving the measurement accuracy.

DETAILED DESCRIPTION ​

[0036] Therefore, it is necessary to provide an ear canal temperature probe with no risk of damaging eardrum.

[0037] Please see Figures 1-2 , Figure 1 The ear canal temperature probe provided in the first embodiment of the present application comprises a flexible earplug body 1, a temperature sensor 2 and a signal transmission component 3.

[0038] The flexible earplug body 1 is made of memory sponge, which can change shape by extrusion before use and slowly recover the original shape over time. The flexible earplug body 1 comprises opposite top end 11 and tail end 12. The top end 11 is arc-shaped. In this embodiment, the surface of the flexible earplug body 1 is marked with a scale 5. In use, the flexible earplug body 1 is extruded into a shape that can enter the ear canal, and then the tail end 12 of the flexible earplug body 1 is pressed against the finger, and the flexible earplug body 1 is sent into the ear canal from the top end 11. When the flexible earplug body 1 recovers its shape, its outer side can be tightly attached to the ear canal, thereby isolating the internal environment of the ear canal from the external environment. The doctor can predict the depth of the ear canal temperature probe inserted into the ear canal by the marking of the scale 5, so as to avoid inserting too deep and damaging the eardrum.

[0039] In this embodiment, the flexible earplug body 1 comprises an insertion section 13 and an external ear section 14, which are connected in a necked shape. The insertion section 13 of the flexible earplug body 1 is conical, which reduces the friction and extrusion of the ear canal during the process of entering the ear canal, so that the probe can enter the ear canal and better fit the ear canal wall. In use, the fingers can pinch the necked part to further send the flexible earplug body 1 into the ear canal.

[0040] The insertion section 13 comprises a measurement section 131 and a transition section 132. The position of the temperature sensor 2 in the flexible earplug body 1 is the measurement section 131 of the insertion section 13. The position of the insertion section 13 that adapts to the shape of the ear canal is the transition section 132. The measurement section 131 and the transition section 132 can be separated, so that there is an air layer in the middle of the flexible earplug body 1. The transition section 132 isolates the external environment from the ear canal environment, but it will conduct a part of the external temperature and neutralize with the air layer. At this time, the temperature of the air layer is close to the temperature of the ear canal. The measurement section 131 further isolates the temperature of the air layer, so that the external temperature cannot be conducted to the ear canal through the flexible earplug body 1, further reducing the influence of the external environment temperature.

[0041] If the distance between the measurement section 131 and the transition section 132 is too long, and the interval part is too soft, it will be inconvenient to send the flexible earplug body 1 into the ear canal. When the distance between the measurement section 131 and the transition section 132 is not greater than 2mm, the hardness of the flexible earplug body 1 itself is sufficient to be sent into the ear canal.

[0042] The temperature sensor 2 is in a cylindrical structure and is embedded in the flexible earplug body 1, with an exposed part on the lower side of the top end 11 of the flexible earplug body 1 and in a circular arc transition with the surface of the flexible earplug body 1, that is, flush with the surface of the flexible earplug body 1. That is, a recess can be formed on the flexible earplug body 1, and the temperature sensor 2 is fixed in the recess by adhesive, so that the surface of the temperature sensor 2 is integrated with the flexible earplug body 1. In the specific use process, the ear canal temperature probe is inserted into the ear canal, and the circular arc surface of the temperature sensor 2 and the surface of the earplug rub against the ear canal to avoid scratching the ear canal due to friction between the corners of the temperature sensor 2 and the ear canal.

[0043] The signal transmission component 3 is signal-interconnected with the temperature sensor 2 to transmit the temperature data collected by the temperature sensor 2. In this embodiment, the signal transmission component 3 is a signal transmission line 31 which is electrically connected with the temperature sensor 2 from the tail end 12 of the earplug body.

[0044] Please refer to Figure 3 , Figure 3 which is a cross-sectional view of the transmission line of the first embodiment of the present application. Two signal transmission lines 31 are respectively connected with the positive and negative electrodes of the temperature sensor 2. The insulating layer on the surface of the transmission line covers the conductive wire. The conductive wire has a high thermal conductivity and is easy to neutralize with the ambient temperature outside the ear canal, thereby affecting the measurement result. In this embodiment, the cross-sectional area of the conductive wire is less than 30 AWG. By reducing the cross-sectional area of the conductive wire, the conduction of the conductive wire to the external environment temperature is reduced, and the measurement accuracy is improved.

[0045] In this embodiment, the part of the signal transmission line 31 embedded in the earplug body is sleeved with a hardening conduit 4 made of hardening material. The hardening material is made of a material with high hardness such as PVC material or TPE material, which has high strength and certain toughness. If the conductive wire is too thin and soft, and the flexible earplug body 1 is also too soft, it is not easy to insert into the ear canal. The hardening conduit 4 can be used as a support to enable the ear canal temperature probe to be inserted straight into the ear canal. The hardening conduit 4 protrudes from the flexible earplug body 1 by not less than 2 mm, and the hardening conduit 4 can be used as a handle. In the specific use, the hardening conduit 4 can be pinched to push the ear canal temperature probe into the ear canal.

[0046] The side surface of the hardening conduit 4 is provided with a limiting rib 41 which is integrally formed with the hardening conduit 4 to strengthen the structure of the hardening conduit 4 and increase the friction between the hardening conduit 4 and the flexible earplug body 1. In the specific use process of the ear canal temperature probe, when the ear canal temperature probe is inserted into the ear canal, the hardening conduit 4 can be rotated to drive the ear canal temperature probe to rotate, so that the ear canal temperature probe is more easily inserted into the ear canal.

[0047] Specifically, in the present embodiment, the flexible earplug body 1 is first squeezed, and then sent into the ear canal. When the flexible earplug body 1 expands, the internal environment of the ear canal is isolated from the external environment. Since the ear canal is close to the eardrum, the temperature in the closed environment is close to the core temperature of the human body. The temperature sensor 2 is tightly attached to the ear canal through the expansion of the flexible earplug body 1, thereby accurately measuring the true ear temperature, i.e., the intracerebral temperature.

[0048] Embodiment 2

[0049] Please refer to Figure 3 The structure of the ear canal temperature probe provided in the second embodiment of the present application is shown in the figure. The difference between the present embodiment and the above-mentioned embodiments is that the control chip 32 and the temperature sensor 2 transmit signals by wireless means. This design makes the ear canal temperature probe unnecessary to be physically connected with a wire, thereby improving the convenience and reliability of use. The control chip 32 is designed with low power consumption and high signal processing capacity, which can efficiently process the data collected by the temperature sensor 2 and send the data to an external receiving device.

[0050] Embodiment 3

[0051] Please refer to Figure 4 The structure of the ear canal temperature probe provided in the third embodiment of the present application is shown in the figure. The difference between the present embodiment and the above-mentioned embodiments is that, in the present embodiment, the flexible earplug body 1 is sleeved with a disposable protective film 6 made of light, thin and transparent material. This design ensures the hygiene and measurement accuracy of the probe every time it is used. The protective film 6 is designed to prevent important components from directly contacting the ear canal, and to avoid the pollution of the ear canal to the flexible earplug body 1, thereby improving the overall service life and hygiene of the probe.

[0052] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
