Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides an earphone for measuring human body vital signs, including: an earphone body 10, a connection member 30, and a detection member 20;
the connecting part 30 is detachably connected with the earphone body 10, and is used for connecting the detecting part 20 to the outside of the earphone body 10, and enabling the detecting part 20 to be close to or contacted with skin tissues of human ears when the earphone body 10 is worn;
the detection component 20 is configured to obtain a vital sign detection value of a human body when the detection component 20 is close to or in contact with skin tissue of a human ear, and transmit the obtained vital sign detection value of the human body to the earphone body 10;
the earphone body 10 is configured to send the vital sign detection value of the human body transmitted by the detection component 20 to the mobile communication device.
The embodiment of the invention provides an earphone for measuring human vital signs, because the earphone for measuring human vital signs in the prior art fixes a detection part in an earphone body, the detection part is fixed at the outer side of the earphone body through a connecting part, because the connecting part is detachably connected with the earphone body, when the human vital sign detection value needs to be obtained, the connecting part can be installed on the earphone body, so that the detection part is close to or contacts with the skin tissue of human ears, when the human vital signs do not need to be detected, the connecting part can be detached from the earphone body, thereby not only saving the internal space of the earphone body, but also not influencing the use of the earphone body; meanwhile, the earphone for measuring the human body vital signs provided by the embodiment of the invention not only can obtain the human body vital sign detection value, but also can send the human body vital sign parameter value obtained by the detection part to the mobile communication equipment through the earphone body, and the human body vital sign detection value can be stored through the mobile communication equipment, so that the statistical processing is facilitated, and people can conveniently sense the own physical health condition; the device is convenient to use and simple to operate; light weight, small volume and convenient carrying.
The vital sign detection value of the human body is obtained by the detection unit 20 from skin tissue of the human ear to obtain vital sign parameters (e.g., respiration, body temperature, heart rate, blood pressure) of the human body, and then the vital sign parameters of the human body are processed into the vital sign detection value of the human body. Preferably, the vital sign detection value of the human body according to the embodiment of the present invention is described by taking a body temperature and a heart rate of the human body as examples.
The detection component 20 is close to the skin tissue of the human ear, that is, the distance between the skin tissue of the human ear and the detection component 20 should be within a detection range of the detection component 20, in which the vital sign parameters in the skin tissue of the human ear can be sensed, which is not limited in the embodiment of the present invention, and the contact of the detection component 20 with the skin tissue of the human ear means that the skin tissue of the human ear is attached to the detection component 20.
Since the distance between the detection component 20 and the skin tissue of the human ear is too far (exceeds the detection range of the detection component 20 that can sense the vital sign parameters in the skin tissue of the human ear), the detection component 20 may not be able to acquire the vital sign parameters from the skin tissue of the human ear, at this time, the connection component 30 may be adjusted so that the detection component 20 may sense the vital sign parameters in the skin tissue of the human ear, and in order to avoid that the vital sign parameters in the skin tissue of the human ear cannot be acquired, it is preferable that the connection component 30 is adjusted so that the detection component 20 is in contact with the skin tissue of the human ear.
The earphone body 10 may be in communication connection with the mobile communication device in various ways, which is not limited in the embodiment of the present invention, and for example, the earphone body may be in communication connection with the mobile communication device through bluetooth, sound wave, WIFI, 3G network, or 4G network.

And after the mobile communication equipment generates the vital sign detection value information, the mobile communication equipment sends recommendation information to the APP on the mobile communication equipment. The user can check the vital sign detection value information after logging in the APP.
In order to facilitate a user to know a vital sign detection value within a normal range or a vital sign detection value within a very normal range in time, for example, an early warning unit may be further disposed on the APP, wherein the early warning unit compares a body temperature or heart rate detection value obtained from the detection component with a normal body temperature value and a normal heart rate detection value stored in advance, and when the vital sign detection value exceeds the normal body temperature value, the normal heart rate detection value, or is lower than the normal body temperature value and the normal heart rate detection value, sends early warning information to the user through a mobile communication device. For example, when the body temperature value of the human body detected by the detecting component 20 is 38 °, and the normal body temperature pre-stored in the APP is 36.5 °, the APP is relatively thick, and the pre-warning information can be sent to the user through a phone number or a social account number bound between the user and the APP.
The normal body temperature value or the normal heart rate value pre-stored in the APP may be manually input by a user, or may be obtained from a server after networking through the APP, which is not limited in the embodiment of the present invention.
