Description
Technical Field
[0001] The present invention relates to the field of medical devices, and particularly to a multifunctional pediatric stethoscope. Background Art
[0002] A stethoscope is a medical device used to listen to internal sounds of the human body and is often an important auxiliary tool for diagnosing certain diseases or health conditions. The stethoscopes currently on the market have deficiencies such as single functions and inability to intuitively display heart rate data, which not only affects the diagnostic efficiency and accuracy but also brings inconvenience to medical staff. In addition, since children are often active and may feel fear and incomprehension during the medical examination process, children often show uncooperative behaviors such as wriggling their bodies or crying. These behaviors not only easily cause the displacement of the stethoscope head, increasing the difficulty of accurate auscultation, but more importantly, they will directly interfere with the sound capture effect of the stethoscope, resulting in unclear sound quality, thus further reducing the diagnostic accuracy.

Detailed implementation manners
[0030] Please refer to Figures 1 - 7, a multifunctional pediatric stethoscope, comprising a stethoscope body 1. The stethoscope body 1 includes a long catheter 11, a stethoscope head 12, a round three-way joint 13, short catheters 14, ear loops 15, earplugs 16 and a spring plate 17. The front end of the long catheter 11 is connected to the stethoscope head 12. The left and right short catheters 14 communicate with the long catheter 11 through the round three-way joint 13. The rear ends of the two short catheters 14 are both connected to the ear loops 15. The rear ends of the two ear loops 15 are both connected to the earplugs 16. A spring plate 17 is connected between the outsides of the two ear loops 15. An annular cavity 2 is opened at the bottom of the stethoscope head 12. A manual air extraction assembly is provided at the top of the stethoscope head 12 for extracting the air in the annular cavity 2, thereby fixing the stethoscope head 12 on the child. The manual air extraction assembly includes a cylinder body 31 embedded and installed on the front side of the top of the stethoscope head 12. The top of the cylinder body 31 is flush with the top of the stethoscope head 12 to hide the cylinder body 31 in the stethoscope head 12, thereby improving the overall aesthetics and the convenience of use of this stethoscope. A piston rod 32 is slidably arranged in the cylinder body 31. A compression spring 33 is connected between the bottom of the piston rod 32 and the inner bottom of the cylinder body 31. The cylinder body 31 is communicated with the annular cavity 2 through an air delivery pipe 34. There are at least two air delivery pipes 34. A sound receiver 41 is installed in the middle of the inner top of the stethoscope head 12 for capturing sound and converting it into an electrical signal. In a specific implementation, the sound receiver 41 is a microphone. The microphone comes with a built-in sound amplifier, which can enhance the intensity of the electrical signal captured by the microphone, thereby improving the clarity of the signal and the accuracy of diagnosis. The microphone with a built-in sound amplifier is a prior art and will not be elaborated here. A loudspeaker 42 is installed on the top of the round three-way joint 13. The loudspeaker 42 is electrically connected to the sound receiver 41. An optical heart rate sensor 51 is installed on the inner bottom of the stethoscope head 12. A display screen 52 is connected to the bottom of the round three-way joint 13. The display screen 52 is electrically connected to the optical heart rate sensor 51. An anti-slip sleeve 6 is connected to the outer wall of the stethoscope head 12. The anti-slip sleeve 6 is made of plastic. The plastic anti-slip sleeve 6 can not only increase the friction with the fingers to prevent slipping, making it easier for medical staff to hold the stethoscope head 12, helping to prevent the stethoscope head 12 from accidentally slipping, but also has good wear resistance and impact resistance, can withstand the wear of daily use, and protect the stethoscope head 12. Finger grooves 61 for the fingers to extend into are opened on the outer wall of the anti-slip sleeve 6. The design of the finger grooves 61 helps to enhance the friction between the hand and the anti-slip sleeve 6, so as to facilitate the medical staff to hold the stethoscope head 12 and ensure the stability and the convenience of operation of the stethoscope head 12 during use. A detachable heater for heating the stethoscope head 12 is provided at the bottom of the anti-slip sleeve 6. The detachable heater includes a mounting shell 73 adsorbed and fixed to the bottom of the anti-slip sleeve 6 through an adsorbing member. The shape of the mounting shell 73 is circular. The top of the mounting shell 73 is of an open type. The adsorbing member includes a first magnetic ring 71 and a second magnetic ring 72. Annular grooves are opened at the bottom of the anti-slip sleeve 6 and the top of the mounting shell 73. The first magnetic ring 71 is connected in the annular groove of the anti-slip sleeve 6. The second magnetic ring 72 is connected in the annular groove of the mounting shell 73. The first magnetic ring 71 and the second magnetic ring 72 attract each other.By installing the first magnetic ring 71 and the second magnetic ring 72 in the annular groove, the first magnetic ring 71 and the second magnetic ring 72 can be hidden, so that the bottom of the anti-slip sleeve 6 is in close contact with the top of the mounting shell 73, thereby improving the overall aesthetics and convenience of use of this stethoscope. A spiral heating wire 74 is installed in the mounting shell 73, and a heat conduction plate 75 is installed above the heating wire 74 in the mounting shell 73. A first switch 76 is installed on the outer wall of the mounting shell 73, and the first switch 76 is electrically connected to the heating wire 74. A second switch 8 is installed on one side of the outer wall of the mounting shell 73 near the first switch 76. The sound receiver 41, the speaker 42, the optical heart rate sensor 51 and the display screen 52 are all electrically connected to the second switch 8.
[0031] Before auscultating a child, first press the first switch 76 to turn on the heating wire 74. The heating wire 74 heats the heat conduction plate 75, and the heat conduction plate 75 then conducts the heat to the stethoscope head 12 to heat the stethoscope head 12, so that the stethoscope head 12 is heated to an appropriate temperature. This can not only improve the comfort of the child during auscultation, but also avoid the discomfort or fright of the child caused by the cold stethoscope head 12 contacting the skin, thereby making the diagnosis more accurate. After the stethoscope head 12 is heated to an appropriate temperature, press the first switch 76 again to turn off the heating wire 74. Then remove the mounting shell 73 from the anti-slip sleeve 6 to avoid hindering subsequent auscultation of the child. The second magnetic ring 72 is separated from the first magnetic ring 71 accordingly. Through the magnetic action of the first magnetic ring 71 and the second magnetic ring 72, the mounting shell 73 can be stably adsorbed and fixed at the bottom of the anti-slip sleeve 6, and the mounting shell 73 can be conveniently and quickly installed and disassembled.
[0032] Then press the piston rod 32 to push the gas in the cylinder body 31 out through the air delivery pipe 34 into the annular cavity 2. The compression spring 33 is compressed. Then place the stethoscope head 12 on the skin of a specific part (such as the chest or back) of the child's body surface. Then release the piston rod 32. Under the reset action of the compression spring 33, the piston rod 32 is pushed upward to draw the air in the annular cavity 2 into the cylinder body 31 through the air delivery pipe 34, thereby creating a negative pressure in the annular cavity 2. This negative pressure can firmly adsorb the stethoscope head 12 on the skin of a specific part (such as the chest or back) of the child's body surface, effectively preventing the stethoscope head 12 from shifting. This not only facilitates auscultation of the child, but also reduces the difficulty of accurate auscultation and improves the auscultation efficiency and accuracy. Similarly, when it is necessary to release the fixation of the stethoscope head 12, just press the piston rod 32 again.
[0033] Subsequently, press switch two 8 to turn on the sound receiver 41, speaker 42, optical heart rate sensor 51, and display screen 52. The optical heart rate sensor 51 can detect the heart beating frequency (heart rate) of a child and transmit the heart beating frequency (heart rate) data to the display screen 52 for display. The display screen 52 can also display the time at the same time. The optical heart rate sensor 51 and the display screen 52 are prior arts and will not be elaborated here. In this way, the heart rate data can be intuitively displayed, further improving the diagnostic efficiency and accuracy. The sound receiver 41 can capture the sound collected by the stethoscope head 12 and convert it into an electrical signal for transmission to the speaker 42. The speaker 42 then converts these electrical signals back into sound and amplifies it, enabling medical staff to hear the heart or lung sounds more clearly. This not only enhances the sound clarity but also further improves the diagnostic efficiency and accuracy. When the stethoscope is not needed for auscultation, press switch two 8 again to turn off the sound receiver 41, speaker 42, optical heart rate sensor 51, and display screen 52, thus saving electricity.
[0034] Please refer to Figures 7 - 9 , a disinfection mechanism is provided at the bottom of the installation shell 73. The disinfection mechanism includes a detachable liquid storage cylinder 91 connected to the bottom of the installation shell 73. The detachable liquid storage cylinder 91 includes an external thread ring 911 and a cylinder 912. The external thread ring 911 is connected to the bottom of the installation shell 73. The top of the cylinder 912 is open. The cylinder 912 is used to store the disinfectant. An internal thread 913 matching the external thread ring 911 is provided on the inner wall of the cylinder 912. The cylinder 912 is connected to the external thread ring 911 through the internal thread 913 thereon. Three electric atomizing nozzles 92 are installed at intervals along the circumference at the bottom of the installation shell 73. The electric atomizing nozzles 92 are communicated with the cylinder 912. The atomizing nozzles of the electric atomizing nozzles 92 extend into the installation shell 73 and are located above the heat conducting plate 75, and are used to spray the disinfectant on the bottom of the stethoscope head 12 to disinfect the stethoscope head 12 and prevent cross-infection. The electric atomizing nozzles 92 are prior arts and will not be elaborated here. A switch three 93 is installed on one side of the outer wall of the installation shell 73 close to the switch two 8. The switch three 93 is electrically connected to the electric atomizing nozzles 92. The colors of the switch one 76, switch two 8, and switch three 93 are different from each other, so as to facilitate quickly identifying and distinguishing the functions of each switch and reducing the risk of misoperation.
[0035] First, unscrew the cylinder 912 from the external thread ring 911, then pour the disinfectant into the cylinder 912. Next, turn the cylinder 912 back onto the external thread ring 911, and the top of the cylinder 912 will be in close contact with the bottom of the mounting shell 73 to prevent the leakage of the disinfectant. Subsequently, the electric atomizing nozzle 92 is connected to the cylinder 912. Press the switch three 93 to turn on the electric atomizing nozzle 92. The electric atomizing nozzle 92 extracts the disinfectant in the cylinder 912 and atomizes and sprays the disinfectant to the bottom of the stethoscope head 12 to disinfect the stethoscope head 12 and prevent cross-infection. Press the switch three 93 again to turn off the electric atomizing nozzle 92. Then, heat the stethoscope head 12 through the detachable heater and heat and evaporate the disinfectant remaining on the stethoscope head 12.
[0036] Please refer to Figures 10 - 11 , two inner and outer sealing rings 21 are connected to the bottom of the stethoscope head 12. The inner sealing ring 21 is located inside the annular cavity 2, and the outer sealing ring 21 is located outside the annular cavity 2. The two inner and outer sealing rings 21 can effectively seal the gap between the stethoscope head 12 and the child's skin, prevent external air from entering the annular cavity 2, and avoid the loosening of the stethoscope head 12 caused by air pressure changes, thereby enhancing the fixing stability of the stethoscope head 12 to ensure the accuracy and reliability of the auscultation process.
