2. Description of the Related Art
When a human body is exposed to contagious bacteria or viruses, the immune system of the human body fights against them, so that a body temperature is increased to a certain level. Here, if the temperature is increased over 38.3° C., we say someone have a high fever. Though not catching a disease, a human body undergoes a procedure of overcoming pathogenic bacteria by means of the immune system, which can be learned by checking whether the temperature is changed, more accurately whether the temperature is increased over a certain level.
In order to measure a body temperature, conventionally, a mercury clinical thermometer was put into the armpit. However, this method takes a relatively long time for measuring the body temperature and does not allow exact temperature detection. Thus, an infrared clinical thermometer is recently put into the ear hole and detects the infrared generated from the eardrum to measure the temperature. The eardrum shares blood with the hypothalamus of the brain that controls the temperature, so that the measurement of temperature of the eardrum is the fastest and most accurate way for checking a change in temperature.
Infrared clinical thermometers are used for measuring a body temperature not only at hospitals but also at houses. In particular, children with a weak immune system frequently have fevers, so that the infrared clinical thermometer is substantially a necessity for homes with children.
Meanwhile, in a case where an ear, nose or throat disease occurs to a child who cannot yet express his/her intention very well, for example in a case where any alien substance enters the ear or nose or the ear or nose is inflamed, the child cries to appeal his/her pain, but his/her parents often worry since they do not know why the child is crying. In such a case, the parents try to check the inside of the ear or nose of the child, but it is not easy since the child struggles to refuse the parents' action. Thus, though the symptom is not serious, the parents should bring the child to the hospital so as to check the reason.
In addition, it is not easy even for an adult to directly check a disease occurring at a dark and narrow spot such as the inside of the ear or nose, so that the adult goes to hospital though the disease is not so serious, which consumes time and cost.
The present invention is conceived to solve the aforementioned problems in the prior art. An object of the present invention is to provide a portable clinical thermometer capable of providing visual images, which has a camera module mounted at a distal end of an ear clinical thermometer commonly used in the art so as to take a body temperature and simultaneously take an image on a region that is suspected as having a disease so that any emergent situation can be easily handled.
A portable clinical thermometer capable of providing visual images according to the present invention comprises a body having an insert provided to protrude at one side thereof so that the insert is inserted into a living body; a clinical thermometer module provided at an inner distal end of the insert to detect infrared emitted from the living body and generate an electric signal corresponding to an intensity of the detected infrared; a camera module provided at the inner distal end of the insert to take an image of an interior of the living body and generate an image signal; a microprocessor for receiving the electric signal generated in the clinical thermometer module to calculate a body temperature and receiving the image signal generated in the camera module to generate an image; a memory for receiving and storing the body temperature information and the image information from the microprocessor; and a display for displaying the body temperature and the image respectively calculated and generated in the microprocessor, wherein the body temperature information and the image information are displayed when being measured, and also changes in body temperature and living body image with the passage of time are displayed using the body temperature information and the image information stored in the memory.
A portable clinical thermometer capable of providing visual images according to the present invention can be carried personally to take a body temperature, and simultaneously, a user of the clinical thermometer can obtain an inner image of the living body with a disease to primarily check occurrence or not of symptom, so that any emergent situation can be easily handled.
