Description

Technical Field

[0001] This invention relates to the field of respiratory monitoring technology, specifically to a respiratory monitoring method and a respiratory monitoring instrument. Background Technology

[0002] Comfortable healthcare refers to providing medical examinations and treatments in a safe and comfortable environment for patients, pursuing comfort and humanization in healthcare while ensuring medical safety.

[0003] Precise drug control and professional anesthesia management enable patients to complete relevant examinations and treatments under sedation, anesthesia, or painlessness, which is an important component of comfortable medical care. Doctors develop individualized anesthesia plans based on the patient's actual condition and closely monitor and manage the entire treatment process.

[0004] Respiratory depression and airway obstruction are the most common complications of anesthesia. To ensure the safety of patients, reliable and accurate respiratory airflow monitoring is the foundation for effective anesthesia management.

[0005] However, among relevant respiratory monitoring techniques, percutaneous oxygen saturation monitoring can dynamically reflect a patient's oxygen supply, but it has a certain lag. Once oxygen saturation drops, the patient may already be facing severe hypoxia. Moreover, end-tidal carbon dioxide monitoring usually needs to be used in a closed breathing circuit or under mechanical ventilation. There are also methods that indirectly reflect lung ventilation function through non-invasive dynamic respiratory monitoring devices, but these are easily interfered with and have a large error compared to the patient's actual ventilation. Summary of the Invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides a respiratory monitoring method to solve at least one of the above-mentioned technical deficiencies in the prior art, so that respiratory monitoring can provide real-time dynamic feedback on the patient's respiratory status, avoid lag, and effectively prevent the patient from facing hypoxia; it no longer needs to be monitored in a closed breathing loop or mechanical ventilation state; it is not easily affected by environmental interference, and can improve the accuracy of monitoring the patient's actual respiratory ventilation.

[0007] To achieve the objective of this invention, a respiratory monitoring method is provided, comprising the following steps:

[0008] A stethoscope base that matches the human larynx is fixed to the human larynx.

[0009] The acquisition element is placed on the stethoscope substrate to acquire the sound of human breathing;

[0010] The human breathing sound collected by the acquisition element is converted into an electrical signal and then input into the feedback element, which provides real-time feedback on the human breathing status.

[0011] Preferably, in the step of setting the acquisition element on the stethoscope substrate to acquire the sound of human breathing, a microphone is used as the acquisition element to acquire the sound of human breathing.

[0012] Preferably, in the step of converting the human breathing sound collected by the acquisition element into an electrical signal and inputting it into a feedback element, and then using the feedback element to provide real-time feedback on the human breathing status, a loudspeaker or a waveform display is used as the feedback element to provide feedback on the human breathing status.

[0013] The present invention also provides a respiratory monitor, which includes:

[0014] The auscultation matrix is ​​designed to match the shape of the human larynx;

[0015] A sound-collecting element is disposed on the stethoscope substrate to collect the sound of human breathing;

[0016] A feedback element is electrically connected to the acquisition element to provide real-time feedback on the human body's breathing status.

[0017] Preferably, it also includes a fixing member, which is connected to the stethoscope base.

[0018] Preferably, the fastener includes a first strap and a second strap.

[0019] The first end of the first strap is fixedly connected to the first end of the stethoscope base, and the first end of the second strap is fixedly connected to the second end of the stethoscope base.

[0020] The second end of the first strap is connected to the second end of the second strap after it is wrapped around the neck of the human body.

[0021] Preferably, the fixing member is a film, the first side of the film is attached and fixed to the stethoscope substrate, and the second side of the film is attached to the neck of the human body.

[0022] Preferably, it also includes an amplifier, the acquisition element is a wireless microphone, and the feedback element is a loudspeaker.

[0023] Both the amplifier and the wireless microphone are mounted on the stethoscope substrate, and the amplifier and the wireless microphone are electrically connected.

[0024] The loudspeaker includes a receiver that is paired with the wireless microphone.

[0025] Preferably, the acquisition element is a transducer, and the feedback element is a waveform display.

[0026] The conductive line electrically connects the transducer to the waveform display.

[0027] Preferably, it also includes an electron transmitter, the acquisition element is a transducer, and the feedback element is a waveform display.

[0028] The electronic transmitter is disposed on the stethoscope substrate, the electronic transmitter is electrically connected to the transducer, and the waveform display receives the signal emitted by the electronic transmitter.

[0029] The beneficial effects of this invention are as follows: The respiratory monitoring method provided by this invention involves fixing an auscultatory base that matches the human larynx at the larynx and placing a collection element on the auscultatory base to collect the sound of human breathing. The sound of human breathing collected by the collection element is then converted into an electrical signal and input into a feedback element, which provides real-time feedback on the human's breathing status. This avoids lag when monitoring a patient's breathing and effectively prevents the patient from facing hypoxia. It eliminates the need for operation in a closed breathing loop or mechanical ventilation state and is less susceptible to environmental interference, thus improving the accuracy of monitoring the patient's actual breathing and ventilation.

[0030] The respiratory monitor provided by this invention features an auscultation base that matches the shape of the human larynx, with a data acquisition element mounted on it. When the auscultation base is placed against the patient's larynx, the data acquisition element can capture the patient's breathing sounds and convert them into electrical signals, which are then transmitted to a feedback element. The feedback element can provide real-time feedback of this electrical signal. This allows the respiratory monitor to provide feedback on the patient's breathing status without lag, effectively preventing the patient from experiencing hypoxia. It eliminates the need for use in a closed breathing loop or under mechanical ventilation and is less susceptible to environmental interference, thus improving the accuracy of monitoring the patient's actual breathing and ventilation.

[0050] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings.

[0051] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] The following is combined with Figures 1 to 10 The embodiments of the present invention will be described below. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any limitation on the present invention.

[0054] Combination Figure 1 The present invention provides a respiratory monitoring method, which includes the following steps:

[0055] Step one: Fix the stethoscope base 100, which matches the human larynx, to the human larynx; this can increase the contact area between the stethoscope base 100 and the human larynx, thereby improving the accuracy of collecting human breathing sounds.

[0056] Step two: The acquisition element 200 is placed on the stethoscope base 100 to acquire human breathing sounds; a microphone can be used as the acquisition element 200 to acquire human breathing sounds. The microphone can be a wireless microphone, which converts the breathing sounds into electrical signals and transmits them to the next receiving unit (e.g., feedback element 300).

[0057] Step three: The human breathing sounds collected by the acquisition element 200 are converted into electrical signals and then input into the feedback element 300. The feedback element 300 provides real-time feedback on the human breathing status. A loudspeaker or a waveform display can be used as the feedback element 300 to provide feedback on the human breathing status.

[0058] When the feedback element 300 is an amplifier, the wireless microphone converts the patient's breathing sound into an electromagnetic signal and transmits it to the amplifier. The amplifier then provides real-time dynamic feedback of the breathing sound to medical staff, enabling them to monitor the patient's breathing status conveniently and in real time, further avoiding delays and effectively preventing the patient from facing hypoxia.

[0059] When the feedback element 300 is a waveform display, the acquisition element 200 can be a transducer. The transducer converts the sound signal into an electrical signal, which is transmitted to the waveform display through the conductive line 500. The waveform display can show the sound waveform of the patient's breathing, making the patient's breathing status visible and facilitating real-time dynamic monitoring by medical staff. The pitch value (i.e., in the Y direction) represents the respiratory gas flow rate, and the width value (i.e., in the X direction) represents the respiratory airflow duration, which includes two phases: inhalation and exhalation.

[0060] It is understood that the respiratory monitoring method provided by the embodiments of the present invention involves fixing an auscultation base 100 that matches the human larynx to the human larynx, and setting a collection element 200 on the auscultation base 100 to collect the sound of human breathing. The human breathing sound collected by the collection element 200 is then converted into an electrical signal and input into a feedback element 300, which provides real-time feedback on the human's breathing status. This avoids lag when monitoring the patient's breathing, effectively preventing the patient from facing hypoxia. It eliminates the need for operation in a closed breathing loop or mechanical ventilation state and is less susceptible to environmental interference, thus improving the accuracy of monitoring the patient's actual breathing and ventilation.

[0061] Combination Figures 2 to 10 The embodiments of the present invention also provide a respiratory monitoring device, which includes an auscultation substrate 100, a data acquisition element 200 and a feedback element 300.

[0062] The auscultation base 100 is designed to match the shape of the human larynx. The auscultation base 100 is curved to conform to the shape of the human larynx, allowing it to be placed close to the skin of the patient's larynx when respiratory monitoring is required.

[0063] The acquisition element 200 is disposed in the auscultation base 100 and can acquire the sound of a patient's breathing. The auscultation base 100 is provided with a receiving groove 110, in which the acquisition element 200 can be disposed for easy installation, disassembly, maintenance and upkeep.

[0064] The feedback element 300 is electrically connected to the acquisition element 200, which can provide real-time feedback on the patient's breathing status.

[0065] It is understood that the respiratory monitor provided in the embodiments of the present invention, by setting an auscultation base 100 that matches the shape of the human larynx and setting a acquisition element 200 on the auscultation base 100, when the auscultation base 100 is attached to the position of the patient's larynx, the acquisition element 200 can collect the patient's breathing sounds and convert the sounds into electrical signals and transmit them to the feedback element 300. The feedback element 300 can provide feedback on the electrical signals in real time. This allows the respiratory monitor to provide feedback on the patient's breathing status, avoiding lag and effectively preventing the patient from facing hypoxia. It no longer needs to be used in a closed breathing loop or mechanical ventilation state. It is also less susceptible to environmental interference and can improve the accuracy of monitoring the patient's actual breathing and ventilation.

[0066] To prevent the stethoscope base 100 from falling off during patient monitoring and to further improve monitoring accuracy, some embodiments of the present invention also include a fixing member 400 connected to the stethoscope base 100. When the stethoscope base 100 is fitted against the patient's larynx, the fixing member 400 can fix the stethoscope base 100 in place, preventing it from loosening when the patient moves or turns over.

[0067] Specifically, the fastener 400 includes a first strap 410 and a second strap 420.

[0068] The first end of the first strap 410 is fixedly connected to the first end of the auscultation base 100, and the first end of the second strap 420 is fixedly connected to the second end of the auscultation base 100.

[0069] The second end of the first strap 410 and the second end of the second strap 420 are connected after passing around the neck of the human body. Using the straps as fasteners 400 makes it simpler, more convenient and faster to fix the stethoscope base 100 to the patient's throat.

[0070] Of course, in some embodiments of the present invention, the fixing member 400 can be a film, with a first side of the film attached and fixed to the stethoscope base 100, and a second side of the film attached to the patient's neck. Using a film as the fixing member 400 makes it easier to apply and remove the film when the stethoscope base 100 is attached and fixed to the patient's throat, and the operation is faster.

[0071] To ensure more stable communication between the feedback element 300 and the acquisition element 200, and to guarantee the stability of the respiratory monitor's monitoring of the patient's breathing, in some embodiments of the present invention, the respiratory monitor further includes a conductive line 500, which electrically connects the acquisition element 200 and the feedback element 300. After the acquisition element 200 collects the patient's breathing sounds and converts them into electrical signals, it transmits them to the feedback element 300 via the conductive line 500. The feedback element 300 then provides feedback so that medical personnel can make timely judgments.

[0072] In some embodiments of the present invention, the auscultation substrate 100 further includes an amplifier 600, the acquisition element 200 can be a wireless microphone, and the feedback element 300 can be a loudspeaker.

[0073] The amplifier 600 and the wireless microphone are both located in the stethoscope base 100. The amplifier 600 is electrically connected to the wireless microphone. The amplifier includes a receiver that is matched with the wireless microphone.

[0074] The amplifier 600 amplifies the patient's breathing sounds and transmits them to a wireless microphone. The wireless microphone converts the patient's breathing sounds into electromagnetic signals and transmits them to a loudspeaker. The loudspeaker then provides real-time dynamic feedback of the breathing sounds to medical staff, enabling them to monitor the patient's breathing status conveniently and in real time, further avoiding delays and effectively preventing the patient from facing hypoxia.

[0075] Of course, in some embodiments of the present invention, the acquisition element 200 can be a transducer, the feedback element 300 can be a waveform display, and the conductive line 500 electrically connects the transducer and the waveform display. The transducer converts the sound signal into an electrical signal, which is transmitted to the waveform display through the conductive line 500. The waveform display can display the sound waveform of the patient's breathing, making the patient's breathing status visible and facilitating real-time dynamic monitoring by medical staff. The pitch value (i.e., in the Y direction) represents the respiratory gas flow rate, and the pitch width value (i.e., in the X direction) represents the respiratory airflow duration, which has two phases: inhalation and exhalation.

[0076] In some embodiments of the present invention, in order to facilitate the movement of the feedback element 300 for monitoring operations at any time, the respiratory monitor also includes an electronic transmitter 700, the acquisition element 200 can be a transducer, and the feedback element 300 can be a waveform display.

[0077] An electronic transmitter 700 is mounted on the auscultation base 100 and is electrically connected to the transducer. A waveform display receives the signal emitted by the electronic transmitter 700. After the transducer converts the sound into an electrical signal, the signal is transmitted to the waveform display via the electronic transmitter 700. The waveform display shows the patient's breathing sounds.

[0078] Combination Figure 9 In some embodiments of the present invention, the feedback element 300 may also be a patient monitor. The patient monitor may also display the waveform of the breathing sound. By connecting to the patient monitor via the plug 800 on the conductive wire 500, the patient's breathing status can be input into the patient monitor, which can be integrated with other monitoring data to reduce the workload of medical staff.

[0079] In this specification, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
