Detailed Description

The invention is further described below with reference to the accompanying drawings.

Please refer to fig. 1, fig. 2 and fig. 3. The utility model discloses an ear lobe blood oxygen saturation detector, including ear clip 1, light emitter 2 and photoreceiver 3 to and data processing unit. Since the oximetry and the components and circuits for data processing therein are already widely used in the prior art, for the sake of convenience of description, the part for converting the signal received by the optical receiver 3 into the required detection data is referred to as "data processing unit" herein, and the detection principle, the data processing method, the specific circuits and the connection manner of the wires thereof are not repeated herein.

The ear clip 1 comprises a first clip body 11 and a second clip body 12, wherein the first clip body 11 and the second clip body 12 are elastically pivoted, and of course, the connection mode can be realized only by an elastic structure or other structures without a pivot in the form of a pair of tweezers or a clip in daily use. The two bodies of the ear clip 1 form a pinna holding portion 18 at the upper end and an earlobe holding portion 19 at the lower end. In a specific embodiment, as shown in fig. 1, the first clip body 11 and the second clip body 12 are symmetrical C-shaped, and the two ends of the C-shape are respectively a pinna clamping part 18 and an earlobe clamping part 19. It can be understood that the first clip body 11 and the second clip body 12 can be in other similar shapes, or the shapes of the two clip bodies are asymmetric, etc., which can achieve the technical effects of the present invention.

The inner side surfaces of the two clamp bodies, which are opposite to the ear lobe clamping part 19, are respectively provided with the light emitter 2 and the light receiver 3 (see fig. 3), so that light with specific wavelength emitted by the light emitter 2 can penetrate through the ear lobe and then can be received by the light receiver 3, and the detection process is realized. Preferably, the optical transmitter 2 and the optical receiver 3 are embedded in the earlobe holding portion 19 and substantially flush with the holding surface of the earlobe holding portion 19 (rather than being protrudingly disposed on the earlobe holding portion 19), so that the optical transmitter 2 and the optical receiver 3 are not damaged by pressure and do not cause pain to the user, and meanwhile, the external influence is avoided and the measurement accuracy is improved.

Preferably, the light emitter 2 and the light receiver 3 are arranged as close to the edge as possible (in use close to the face), which facilitates the determination of the position from the outside and can be adapted to the case of small earlobes.

When the ear clip is used, the ear clip 1 is opened and clipped on the ear of a user, the light emitter 2 and the light receiver 3 on the inner side of the ear lobe clamping part 19 are ensured to be positioned at the ear lobe position of the user, and the ear guo clamping part 18 on the upper part is naturally clamped on the ear guo after the hand is loosened.

The ear clip 1 of the utility model is provided with an ear lobe clamping part 19 and an ear guo clamping part 18, thereby increasing the total area of the ear clip 1 for clamping ears, reducing the pressure intensity and ensuring that users are not easy to feel pain; meanwhile, the clamping is firmer and is not easy to fall off; and does not feel uncomfortable as the earlobe is pulled. On the other hand, because this structure, to the user that the ear size, shape are different, the utility model discloses the homoenergetic stably centre gripping detects the oxyhemoglobin saturation of its earlobe department. Specifically, for example, the product is made into the size of a normal ear, and when the product is used, the position of the pinna clamping part 18 is slightly lower when the ear is bigger; for the case of small ears, the position of the pinna clamping part 18 is slightly higher, so that the stable clamping effect can be achieved.

Preferably, as shown in fig. 2, the first clip body 11 and the second clip body 12 are curved when viewed from the side, and a space for receiving an ear is formed between the two clip bodies. Therefore, the whole pinna can not be clamped flat when in use, thereby being more comfortable to use. For this purpose, as in another embodiment, the first clip 11 and the second clip 12 may be flat plates, and a boss may be added at the position of the inner pinna holding portion 18 and/or the ear lobe holding portion 19, and the joint of the two clip ends may have a certain distance, so as to form a space for receiving ears. It will be appreciated that a design with both a radius and a boss is also possible. Of course, whichever way, the pinna clamp 18 and the earlobe clamp 19 need to be substantially flush from the side to achieve simultaneous clamping of the pinna upper end and the earlobe.

Preferably, the first clip body 11 and the second clip body 12 are provided with knobs 17. Without the proposal of the handle 17, the two clamp bodies can be separated by hands, and the whole volume is smaller and the weight is lighter; and the presence of the knob 17 makes the process of separating the clip body easier.

Preferably, all be provided with cushion 181 on the relative two medial surfaces of two clamp pinna clamping parts 18, its material such as sponge, like this, further avoided the centre gripping to produce painful sense on the one hand, the cushion 181 of on the other hand compressed can form the shape of laminating pinna to the centre gripping is more stable, more is difficult to the slippage.

Preferably, as shown in fig. 3, a movable structure 15 is provided between the ear lobe holding portion 19 and the rest of the clip body where the ear lobe holding portion is located, so that the outer side of the ear lobe holding portion 19 can be lightly pinched during use, thereby further ensuring that the optical emitter 2 and the optical receiver 3 are tightly attached to the ear lobe and improving the detection accuracy. In one embodiment, the movable structure 15 is a damping pivot, and the earlobe holder 19 is hinged to the rest of the clamp body via the damping pivot. In another embodiment, the movable structure 15 is a flexible and flexible filament/strip, such as a wire, disposed at the junction of the ear lobe retaining portion 19 and the rest of the clip body, and the outer layer is made of a flexible material, such as silicone, to prevent discomfort to the user due to the low temperature of the wire and to slow the corrosion rate of the wire.

The utility model relates to an among the concrete implementation mode, there are optical emitter 2 and optical receiver 3 on the ear clip 1, nevertheless do not contain the part of whole data processing and demonstration, through connect out the wire from ear clip 1, external in other equipment, like the ECG monitor to realize data processing and demonstration, be similar to the finger clip formula oximeter of the external watch formula wearing equipment that has used widely at present, this external device and specific circuit etc. also no longer give consideration to any more.

In a preferred embodiment, as shown in fig. 4, the electronic display screen 8 and the switch button 9 are disposed on the ear clip 1 (on the outward surface of the first clip body 11 or the second clip body 12), the first clip body 11 and/or the second clip body 12 are thickened, a cavity is disposed inside the first clip body 11 and/or the second clip body 12 for placing a power source, such as a button battery, and a data processing unit, similar to the current portable finger clip type oximeter, and the detailed circuits and the like are not repeated.

It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
