Description

Technical Field

[0001] The utility model belongs to the technical field of body temperature measuring instruments, and in particular relates to a fever body temperature measuring instrument. Background Art

[0002] A thermometer is used to measure the temperature of a patient with fever in a hospital. The patient's temperature can be measured by the thermometer. The thermometer is aimed at the patient's forehead and infrared radiation is emitted to the patient's forehead through the infrared measurement area on the thermometer. The infrared measurement area includes an infrared LED and a photodiode. The infrared LED emits red light to the patient's forehead, which is reflected back after touching the patient's forehead. The red light is emitted into the photodiode and then converted into a measurable electrical signal and displayed on the display.

[0003] When the existing fever thermometer is in use, under normal use, the distance between the infrared measurement area on the thermometer and the forehead should be between three centimeters and five centimeters, so that the measurement is most accurate. However, when a person holds the thermometer to measure the patient's temperature, it is easy to misjudge the distance between the infrared measurement area on the thermometer and the patient's forehead. If the distance is too close, it may affect the measurement accuracy, so that the data obtained is inaccurate. If the distance is too far, it will also affect the measurement accuracy, because the emitted red light will weaken with the increase of distance, thereby affecting the measurement result. For this reason, we propose a fever thermometer. Utility Model Content

[0020] Example

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a fever body temperature measuring instrument, including a body 100, a measuring head 103, and an auxiliary positioning laser point 105 and an infrared measuring area 104 arranged on the measuring head 103. The infrared measuring area 104 includes an infrared LED and a photodiode. When in use, the infrared measuring area 104 emits infrared radiation to the patient's forehead. The infrared measuring area 104 includes an infrared LED and a photodiode. The infrared LED emits red light to the patient's forehead, and after touching the patient's forehead, it is reflected back. The red light is emitted and enters the photodiode and then The measuring head 103 is provided with a limiting mechanism on the top of the measuring head 103, which includes a limiting member and a buffer member. The limiting member includes a fixed ring 206 and a moving rod 202. The end of the moving rod 202 passes through the interior of the fixed ring 206. When in use, the moving rod 202 can move to the left or right in the interior of the fixed ring 206. The buffer member includes a rubber plate 201, which is fixed to the end of the moving rod 202. A rubber buffer ball 200 is fixed on the rubber plate 201. The top of the fixed ring 206 is fixedly provided with an arc scale plate 203, and the outer wall of the arc scale plate 203 is provided with multiple groups of scale lines. The interior of the fixed ring 206 is provided with a screw hole, and the screw hole is connected to the screw rod 205 by a thread when in use. The screw rod 205 is provided inside the screw hole, and the bottom of the screw rod 205 extends to the surface of the moving rod 202. The top of the fixed ring 206 is fixedly provided with an extension strip 204, and the end of the extension strip 204 is fixedly provided with an indication arrow 207. Through the designed limiting mechanism, it is convenient to first move the moving rod 202 in use. Move left and right in the fixing ring 206 to adjust the position so that the distance between the rubber buffer ball 200 and the measuring head 103 is between three and five centimeters. When measuring the patient's temperature, align the infrared measuring area 104 on the thermometer with the patient's forehead and make the rubber buffer ball 200 contact the patient's forehead. At this time, the distance between the infrared measuring area 104 and the patient's forehead is between three and five centimeters, which is a suitable measurement distance. This avoids inaccurate measurement due to inaccurate distance from the patient's forehead, thereby improving the measurement effect of the thermometer.

[0022] In this embodiment, preferably, a fixing plate 300 is fixedly provided at the bottom of the fixing ring 206, and the fixing plate 300 is located on the top of the measuring head 103. The fixing plate 300 and the body 100 are fixedly connected by two sets of screws, and the limiting mechanism can be disassembled and assembled by the screws when in use.

[0023] In this embodiment, preferably, a display screen 101 is embedded and installed on the side of the body 100 , and a plurality of groups of buttons 102 are also arranged on the side of the body 100 .

[0024] In this embodiment, preferably, a button 106 is provided on the machine body 100 , and the measuring head 103 is fixed on the machine body 100 .

[0025] The working principle and use process of this utility model:

[0026] The model of the thermometer used in the utility model is ST390A. When in use, the screw rod 205 is rotated upward to loosen it. At this time, the bottom of the screw rod 205 is no longer in contact with the surface of the moving rod 202. Then the moving rod 202 is moved to the left or right, driving the arc scale plate 203, the rubber plate 201 and the rubber buffer ball 200 to move. Then, the indicating arrow 207 at the bottom of the extension strip 204 is aligned with the corresponding scale line on the lower arc scale plate 203, so that the distance between the rubber buffer ball 200 and the measuring head 103 is three to five centimeters. At this time, the distance can be adjusted, and then the distance between the rubber buffer ball 200 and the infrared measurement area 104 is three to five centimeters. Then, the screw rod 205 is tightened downward, and then when measuring, the thermometer is picked up by hand and aimed at the patient's forehead, so that the rubber buffer ball 200 is in contact with the patient's forehead. At this time, the distance between the patient's forehead and the infrared measurement area 104 is three to five centimeters. At this time, the measurement distance can be accurately grasped, and the accuracy of the measurement structure is increased.

[0027] The fixing plate 300 can be removed by unscrewing the screws on the fixing plate 300 , and then the limiting mechanism can be removed. The limiting mechanism can be installed by operating according to the reverse principle.
