Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary instruments, and particularly relates to a headset-type mini portable ear thermometer. Background Art

[0002] Measuring body temperature is an important step in medical practice to determine whether there is a fever. Body temperature measurement is divided into axillary temperature, ear temperature, forehead temperature, sublingual temperature, rectal temperature, etc. Among them, axillary temperature, sublingual temperature, and rectal temperature are all measured using mercury thermometers or electronic thermometers; ear thermometers use infrared measurement technology. The probe is inserted into the ear canal, and the ear temperature is quickly measured. After adding the oral temperature compensation value, the equivalent oral temperature is displayed; the ear thermometer is a non-contact remote measurement type (although it may be less than one centimeter) temperature measuring instrument. It uses the infrared spectrum emitted by the eardrum (equivalent to the hypothalamus) to determine the body temperature. According to the blackbody radiation theory, the infrared spectra generated by objects at different temperatures are also different. Using a thermopile infrared detector that can be accurate to 0.1 °C, and then the reading is converted by a microcomputer and displayed.

[0003] Currently, when measuring body temperature with an ear thermometer, it is generally used together with a sheath (also known as an ear tip). When using it, the auricle needs to be pulled backward, and the probe is inserted into the ear canal to ensure that the probe and the eardrum are on the same horizontal line to obtain the correct value. The function of the sheath is to isolate the probe and the ear canal, prevent the ear thermometer from contacting the ear canal of the person being tested, avoid the spread of skin diseases, and avoid cross-infection.

[0004] During operation, the insertion rod with the probe is directly inserted into the ear canal for measurement. Due to operational errors, inserting the probe directly into the ear canal without using an ear tip is likely to damage the inner wall of the ear canal and the probe due to incorrect operation; when using an ear tip, the position of the probe and the eardrum may be affected due to errors between the ear tip and the probe. Therefore, when inserting into the ear canal, it needs to move forward slowly to ensure that the probe does not touch the inner wall of the ear canal and is facing the ear canal for detection, so that the detected value will be more accurate. Currently, ear thermometers are taken out for temperature measurement only when needed, and they are items for intermittent use. Therefore, there is a need for an ear thermometer that is small in size, uses Bluetooth transmission, and is portable for long-term temperature measurement. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the probe and the eardrum cannot be aligned in the prior art, and thus provide a headset-type mini portable ear thermometer.

[0032] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] A headset-type mini portable ear thermometer, as Figure 1As shown, a probe 2 is fixedly arranged on the main body 1. An ear temperature sleeve 3 is sleeved outside the probe 2. The ear temperature sleeve 3 is snap-connected with the probe 2. The top end of the ear temperature sleeve 3 is spherical, and the inside of the ear temperature sleeve 3 is hollow. This structure lacks the screen display part compared with other ear thermometers, reducing the volume and being small and compact.

[0034] As Figure 1 and Figure 2 As shown, the probe 2 includes a housing 21 and an internal component 22. The internal component 22 includes a support structure 221 and a temperature measuring column 222. The housing 21 is used to wrap the internal component 22, completely isolating the temperature measuring component from the inner ear canal environment, preventing ear canal secretions and debris from entering the internal component 22 during the use of the ear thermometer and affecting its operation, improving the accuracy of the ear thermometer for temperature measurement. A temperature measuring chip 2221 is fixedly arranged on the temperature measuring column 222. The temperature measuring chip 2221 is electrically connected to the main body 1. The support structure 221 surrounds the outside of the temperature measuring column 222. The support structure 221 includes a fixing rod 2211 and a fixing ball 2212. One end of the fixing rod 2211 is fixed on the temperature measuring column 222, and the other end is fixed on the fixing ball 2212.

[0035] As Figure 2 and Figure 3 As shown, the fixing rod 2211 is inserted and fixed with the temperature measuring column 222. A plurality of fixing rods 2211 are arranged in a circumferential array along the temperature measuring column 222. The fixing ball 2212 is ball-joint connected with the housing 21. A corresponding hinge point is arranged inside the housing 21. The fixing ball 2212 is fixed on the side wall of the temperature measuring column 222 through the fixing rod 2211, playing a protective role for the side wall of the temperature measuring column 222, effectively preventing the inner wall of the ear canal, secretions and debris from contacting the sealed tube. When the probe 2 is inserted into the ear canal, the fixing ball 2212 contacts and supports against the inner wall of the ear canal. Since the fixing rod 2211 is inserted into the temperature measuring column 222, a sliding space is left in the temperature measuring column 222, and the fixing ball 2212 is ball-joint connected with the housing 21. Thus, when the entire probe 2 enters the ear canal, the outer support structure 221 can be continuously adjusted, but the vertical setting of the middle temperature measuring column 222 is ensured, so as to ensure that the probe 2 and the eardrum are on the same horizontal line during temperature measurement.

[0036] As Figure 2 and Figure 3As shown, the ear temperature sleeve 3 is snap-connected to the probe 2. The length of the ear temperature sleeve 3 is slightly longer than that of the probe 2. The ear temperature sleeve 3 is designed as a hollow transparent film. The bottom end of the ear temperature sleeve 3 extends with a folding part 31. A strengthening structure 32 is fixedly arranged on the ear temperature sleeve 3. At least one layer of heat insulation layer is coated on the outer side of the side wall of the ear temperature sleeve 3. Since the ear temperature sleeve 3 is relatively thin, the strengthening structure 32 is provided. The strengthening structure 32 can be a raised or sunken indentation. The strengthening structure 32 is a ring-shaped or arc-shaped structure arranged along the circumference of the ear temperature sleeve 3. The ear temperature sleeve 3 is a disposable consumable. After use, it can be discarded and a new ear temperature sleeve 3 can be replaced for the next detection to avoid cross-infection. The ear temperature sleeve 3 has uniform thickness. The film-shaped ear temperature sleeve 3 has high consistency and good light transmission effect, which helps the ear thermometer to perform accurate detection and is conducive to ensuring the accuracy of detection and treatment. The top end of the ear temperature sleeve 3 is spherical, which is convenient for slow sliding in the ear canal and reduces friction with the ear canal. The heat insulation layer on the outer side of the side wall of the ear temperature sleeve 3 reduces the influence of non-temperature measurement parts on the temperature measurement part.

[0037] As Figure 2 and Figure 4 shown, the housing 21 is plugged and fixed to the main body 1. The top end of the housing 21 is provided with an opening. A ring-shaped plug-in card 211 is arranged at the bottom end of the housing 21. A ring-shaped groove 15 is formed on the main body 1. Symmetrically extending in the ring-shaped groove 15 are positioning cards 151 with inclined surfaces. A groove 2111 corresponding to the positioning card 151 is formed on the plug-in card 211. The use of the snap connection structure facilitates the installation of the housing 21 and is also conducive to the replacement of subsequent internal parts. The existence of the positioning card 151 reduces the risk of the housing 21 falling off.

[0038] As Figure 2 and Figure 5 shown, a control circuit 11, a signal transmission module 12, a battery 13 and a sensor 14 are arranged in the main body 1. The battery 13 supplies power to the main body 1. The control circuit 11 includes at least one micro programmable logic controller 111 capable of data storage. The programmable logic controller 111 controls the actions of the sensor 14 and the temperature measurement chip 2221. At the same time, the programmable logic controller 111 is used to store and remember the temperature data of the temperature measurement chip 2221 and transmit the data outward through the signal transmission module 12. With the setting of the control circuit 11, the user can control the actions of the sensor 14 and the temperature measurement chip 2221 through the logic control unit 1112. The sensor 14 is a Hall sensor 14, which is used to detect the opening of the box stored by the ear thermometer. The database unit 1111 will store and remember the temperature data measured by the temperature measurement chip 2221 each time, and can be transmitted to a personal terminal through the signal transmission module 12 (Bluetooth IC). The operation is simple and convenient. The programmable logic controller instantaneously transmits and stores to prevent data loss.

[0039] As Figure 1 and Figure 5As shown, this ear thermometer uses a signal transmission module 12 with a built-in Bluetooth headset function, which can receive electrical signals emitted by a media player or a receiver. Its wireless transmission ability can meet the needs of the vast majority of users. Moreover, no screen is added to the ear thermometer itself, so the overall volume of the ear thermometer is reduced, making it more portable, miniaturized and convenient, and capable of long-term wearing for long-term dynamic body temperature monitoring.

[0040] As Figure 4 shown, the normal operating parameters and / or service life information of each component are stored in the programmable logic controller 111. Whether a component needs to be replaced or repaired is judged according to the normal operating parameters and / or service life information of each component. If so, the alarm unit 1113 is controlled to give a local and / or remote warning, realizing the early warning function of the working state of each component, reminding the user in advance to replace or repair, and ensuring that the ear thermometer is in a good working state.

[0041] The working principle of this ear thermometer: Before use, install the probe 2, and then cover the probe 2 with a disposable ear tip 3; after installation, insert the entire probe 2 into the ear canal, and fine-tune the positions of the housing 21 and the temperature measuring column 222 through the fixing ball 2212 to ensure the vertical state of the temperature measuring column 222. After the probe 2 enters deep enough, the probe 2 and the eardrum should be on the same horizontal line before measuring the temperature; after the temperature measurement is completed, it is output to the personal terminal through the signal transmission module 12. This ear thermometer can achieve long-term continuous dynamic monitoring rather than single-use temperature measurement compared with the current ear thermometers.

[0042] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
