Description

Technical Field

[0001] This utility model relates to the field of body temperature measurement technology, specifically to an electronic rectal thermometer for newborns. Background Technology

[0002] Currently, most common electronic thermometers consist of three parts connected together: a temperature-sensing steel sleeve (also called a temperature-sensing head), a rigid plastic shell, and a back cover. For easy reading and operation, the rear of the rigid plastic shell features an LCD display and a rigid plastic switch button. However, using a traditional rigid plastic switch button can lead to poor mechanical contact, reducing the reliability of the switch control.

[0003] For example, CN202836773U discloses an electronic thermometer, which includes a temperature sensing head, a housing, and a rear cover. The rear end of the housing is equipped with an LCD screen and a power button. The housing also has a flexible front end, with its two ends connected to the temperature sensing head and the rear end, respectively. This electronic thermometer can be bent in multiple directions and is suitable for measurements in specific locations such as the mouth, armpit, and rectum.

[0004] However, using traditional hard plastic switches can lead to poor mechanical button contact, reducing the reliability of switch control. After prolonged use, the internal metal contacts of mechanical buttons are prone to oxidation, wear, or elasticity loss due to frequent pressing, resulting in increased contact resistance, unstable signal transmission, and even button malfunction. Especially in medical settings, neonatal rectal thermometers require frequent use and sterilization, and the humid environment accelerates the aging of mechanical buttons, affecting the normal startup and temperature measurement process of the device, and increasing the operational burden on medical staff. Therefore, those skilled in the art provide an electronic rectal thermometer for newborns to solve the problems mentioned in the background. Utility Model Content

[0005] The purpose of this invention is to provide a newborn electronic rectal thermometer that solves the problem of poor mechanical button contact caused by the use of traditional hard plastic switch buttons in the prior art, which reduces the reliability of switch control.

[0006] This utility model provides the following technical solution: a neonatal electronic rectal thermometer, including a soft grip for medical personnel to hold, one end of the soft grip being fixedly connected to a soft front end for connecting the soft grip, the end of the soft front end away from the soft grip being fixedly connected to a blunt tip for adhering to the rectal mucosa, a battery pack for providing power being provided on the side of the soft grip away from the soft front end, and the battery pack and the soft grip being detachable.

[0007] As a preferred embodiment of the above technical solution, the inner cavity at the center of the upper end of the soft grip part is provided with a display screen for displaying temperature, and the inner cavity at the side of the upper end of the soft grip part is provided with a touch switch for controlling the switch of the rectal thermometer.

[0008] As a preferred embodiment of the above technical solution, the inner cavity of the soft grip portion is fixedly connected to a control connection line for transmitting touch switch signals, and the upper end of the control connection line is electrically connected to the touch switch through the soft grip portion.

[0010] As a preferred embodiment of the above technical solution, a signal transmitter for transmitting signals to the display screen is fixedly connected to the top of the signal controller, and the signal transmitter is electrically connected to the display screen through a soft grip part.

[0011] As a preferred embodiment of the above technical solution, the end of the signal controller away from the reinforced joint is fixedly connected to a signal processor for processing infrared signals, the end of the signal processor away from the signal controller is fixedly connected to a temperature sensor for transmitting temperature, and the end of the temperature sensor away from the signal processor is fixedly connected to a signal receiver for receiving infrared signals.

[0012] As a preferred embodiment of the above technical solution, the inner cavity of the soft front end is provided with an infrared emitting groove that runs through the soft grip part and the blunt end for transmitting infrared signals, and one end of the infrared emitting groove near the soft grip part is in close contact with the signal receiver.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a touch switch. Medical staff hold the soft grip and gently insert the blunt tip into the newborn's rectum. The soft tip naturally bends with the tissue's shape. The battery pack provides power during this process. The touch switch recognizes the touch action through a capacitive sensing mechanism. Upon triggering, it generates an electrical signal that is transmitted to the signal controller via a control connection line and a reinforced connector, initiating the device's signal transmission and processing flow.

[0015] Based on the above-mentioned beneficial effects, this utility model is equipped with a signal processing component. When the touch switch is pressed, the battery power supply circuit is connected, the signal controller is started, the temperature sensor senses the temperature of the rectal wall and generates a change in resistance or voltage, the analog signal is amplified by the signal processor and converted from analog to digital signal, the signal receiver receives the infrared signal, the signal processor calibrates and calculates to generate a body temperature value, and then transmits it to the display screen through the signal controller and signal transmitter.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a neonatal electronic rectal thermometer, including a soft grip part 1 for medical personnel to hold, a soft front end 2 for connecting the soft grip part 1 fixedly connected to one end of the soft grip part 1, a blunt tip 3 for adhering to the rectal mucosa fixedly connected to the end of the soft front end 2 away from the soft grip part 1, a battery pack 4 for providing power is provided on the side of the soft grip part 1 away from the soft front end 2, and the battery pack 4 and the soft grip part 1 are detachable.

[0023] Medical staff hold the soft grip part 1 and gently insert the blunt tip 3 into the newborn's rectum. During this process, the soft tip 2 naturally bends according to the tissue shape, and the battery pack 4 powers the device. At this time, the blunt tip 3 is close to the rectal wall, and the temperature sensor 12 senses the body temperature through the internal structure of the soft tip 2. The subsequent signal is transmitted to the display screen 5 via components such as the infrared emitter 14. The detachable design ensures that battery replacement does not affect the main structure, ensuring a continuous measurement process.

[0024] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a display screen 5 for displaying temperature is provided in the inner cavity at the center of the upper end of the soft grip part 1, and a touch switch 6 for controlling the switch of the rectal thermometer is provided in the inner cavity at the side of the upper end of the soft grip part 1.

[0025] After pressing the touch switch 6, the power supply circuit of the battery pack 4 is connected, and the signal controller 9 is activated. The body temperature data collected by the temperature sensor 12 is converted into an electrical signal by the signal processor 11 and transmitted to the display screen 5 through the signal transmitter 10 for real-time digital display. The capacitive sensing mechanism of the touch switch 6 can recognize light touches, avoiding poor contact caused by frequent pressing of mechanical buttons and ensuring the reliability of switch control.

[0026] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a control connection line 7 for transmitting signals of the touch switch 6 is fixedly connected to the inner cavity of the soft grip part 1, and the upper end of the control connection line 7 is electrically connected to the touch switch 6 through the soft grip part 1.

[0027] When the touch switch 6 is triggered, the generated electrical signal is transmitted to the reinforced connector 8 through the control connection line 7. The metal contacts inside the connector are tightly connected to the input terminal of the signal controller 9, forming a complete signal transmission path.

[0028] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a reinforcing connector 8 is fixedly connected to the end of the control connection line 7 away from the soft grip part 1, and a signal controller 9 for controlling signal transmission is fixedly connected to the end of the reinforcing connector 8 away from the control connection line 7.

[0029] The reinforcement connector 8 uses injection molding or threaded fixing to fix the shielding layer of the connecting wire and the signal wire separately, preventing the signal wire from detaching from the controller when pulled, and ensuring the stability of signal transmission.

[0030] As one implementation method in this embodiment, please refer to... Figures 1-3 As shown, a signal transmitter 10 for transmitting signals to the display screen 5 is fixedly connected to the top of the signal controller 9, and the signal transmitter 10 is electrically connected to the display screen 5 through the soft grip part 1.

[0031] The signal controller 9, with its built-in microprocessor, receives the switch signal from the control connection line 7 and sends a start command to the temperature sensor 12. The temperature sensor 12 collects body temperature data and converts it into an analog signal. After being amplified and filtered by the signal processor 11, it is converted into a digital signal by the signal controller 9 and then transmitted to the display screen 5 driver chip via the signal transmitter 10, ultimately displaying the temperature value on the screen. The signal transmitter 10 uses differential signal transmission to reduce external electromagnetic interference and ensure the accuracy of data transmission.

[0032] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a signal processor 11 for processing infrared signals is fixedly connected to the end of the signal controller 9 away from the reinforcing connector 8. A temperature sensor 12 for transmitting temperature is fixedly connected to the end of the signal processor 11 away from the signal controller 9. A signal receiver 13 for receiving infrared signals is fixedly connected to the end of the temperature sensor 12 away from the signal processor 11.

[0033] Temperature sensor 12 senses the temperature of the rectal wall and generates a change in resistance or voltage. Its analog signal is amplified by the operational amplifier of signal processor 11 and then converted into a digital signal by analog-to-digital converter. Signal receiver 13 is located at the end of infrared emitting slot 14 of soft end 2 and receives infrared signal from temperature sensor 12. When the temperature is higher, the infrared radiation intensity is greater and the signal is transmitted to signal processor 11 for calibration and calculation, and finally generates an accurate body temperature value.

[0034] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the inner cavity of the soft front end 2 is provided with an infrared emitting groove 14 that passes through the soft grip part 1 and the blunt end 3 for transmitting infrared signals. The end of the infrared emitting groove 14 near the soft grip part 1 is in close contact with the signal receiver 13.

[0035] The infrared emitting slot 14 has a hollow interior and its surface is covered with reflective material to reduce the scattering and absorption of infrared signals during transmission. When the temperature sensor 12 generates an infrared signal, the signal travels directly through the emitting slot to the signal receiver 13, resulting in a short transmission path and low loss. The diameter and curvature of the emitting slot are designed according to the infrared signal wavelength to ensure signal transmission efficiency, thereby enabling real-time acquisition and display of body temperature data.

[0036] Working principle: Medical staff hold the soft grip part 1 and gently insert the blunt tip 3 into the newborn's rectum. The soft front end 2 naturally bends with the tissue shape. The battery pack 4 provides power during this process. The touch switch 6 recognizes the light touch through a capacitive sensing mechanism. After being triggered, it generates an electrical signal, which is transmitted to the signal controller 9 through the control connection line 7 and the reinforced connector 8. This initiates the equipment's signal transmission and processing process, avoiding the problem of poor contact of mechanical buttons, ensuring the reliability of switch control, and enabling the normal start and operation of signal transmission and display throughout the entire body temperature measurement process.

[0037] Then, press the touch switch 6, the power supply circuit of the battery pack 4 is turned on, the signal controller 9 is started, the temperature sensor 12 senses the temperature of the rectal wall and generates a change in resistance or voltage, the analog signal is amplified by the signal processor 11 and converted from analog to digital signal, the signal receiver 13 receives the infrared signal, the signal processor 11 calibrates and calculates to generate the body temperature value, and then transmits it to the display screen 5 through the signal controller 9 and the signal transmitter 10.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
