TECHNICAL FIELD
[0001] The utility model relates to medical care technical field, concretely relates to a pressure type nasal airflow snore sound sensor. BACKGROUND
[0002] Sleep accounts for about one third of people's life, and sleep disorders have become a health problem of most people's concern. Sleep apnea syndrome (SAS) is a sleep disorder that causes medical concern, which is snoring accompanied by sleep apnea. Since Polysomnogram (PSG) is currently the "gold standard" for diagnosing sleep apnea syndrome, in clinical practice, the PSG of patients is obtained by a polysomnogram monitor for diagnosis. Snoring sound, as an important physiological parameter for diagnosing sleep apnea, has become an essential auxiliary monitoring item of the polysomnogram monitor. Therefore, the snoring sound sensor has become a standard configuration of the polysomnogram monitor.
[0003] Currently, the oral and nasal airflow breathing movement sensors for sleep monitoring systems are mostly thermal type (thermistor, thermocouple). This type of sensor converts the temperature change of the monitored person's oral and nasal breathing gas into a change in resistance or voltage value to reflect the breathing movement waveform. For example, a sensor for measuring the oral and nasal breathing movement waveform of the human body is developed by using the giant stress impedance effect of amorphous wire, as disclosed in the patent with publication number 222. The sensor has a similar shape to a headset, and is worn on the head during monitoring. The sensor probe is fixed in front of the mouth and nose. When breathing, the airflow at the mouth and nose acts on the amorphous wire in the membrane, and the impedance of the amorphous wire changes synchronously with the force received. The breathing waveform signal is obtained through circuit processing. The snoring sound sensor for sleep monitoring systems is mostly of the microphone type and the piezoelectric crystal type. This type of sensor transmits the vibration caused by snoring to the sensor and converts it into a change in voltage value to reflect the snoring movement waveform.

It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.
[0032] In order to solve the technical problems that the sensor is easy to be corroded by humid airflow in use, the service life is short, the sensor needs to be cleaned and disinfected after use, the medical tape for fixing the sensor can be off, and the user feels uncomfortable, the utility model provides a pressure type nasal airflow snore sensor, nasal oxygen hose is used for guiding the nasal cavity gas to the detection surface of the sensor body, the sensor body is used for detecting the breathing movement state and the snoring state, the detection of the breathing movement state and the snoring movement state can be realized at the same time, the comfort of the wearer in the sleep monitoring process is improved, the contact between the sensor body and the humid oral and nasal airflow is reduced, therefore, the sensor body does not need to be cleaned and disinfected frequently, the service life of the sensor is prolonged, and the manufacturing and use costs are reduced.
[0033] Please refer to Figure 1 and Figure 2 , the pressure type nasal airflow snore sensor comprises an outer shell 1, a sensor body 2, a connecting assembly 3 and a nasal oxygen hose 4, the sensor body 2 is arranged in the inner part of the outer shell 1 and is used for detecting the breathing movement waveform and the snoring waveform, the connecting assembly 3 is connected with the outer shell 1, one end of the nasal oxygen hose 4 is used for connecting the human nasal cavity, the other end is connected with the connecting assembly 3 in a sealed mode, and the nasal cavity gas can be guided to the detection surface of the sensor body 2.
[0034] In the device, the sensor body 2 is arranged in the inner part of the outer shell 1, is connected with the nasal oxygen hose 4 through the connecting assembly 3, is connected with the human nasal cavity through the nasal oxygen hose 4, the nasal cavity gas is guided to the detection surface of the sensor body 2 through the nasal oxygen hose 4 in use, the breathing movement waveform and the snoring waveform are detected through the sensor body 2, the detection of the breathing movement waveform and the snoring movement waveform can be realized at the same time, the material of the nasal oxygen hose 4 is soft and has good biocompatibility, the human nasal cavity can be easily connected, the discomfort of the nasal cavity is not caused even if the nasal oxygen hose 4 is used for a long time, the comfort of the wearer in the sleep monitoring process is improved, the contact between the sensor body 2 and the humid oral and nasal airflow is reduced, therefore, the sensor body 2 does not need to be cleaned and disinfected frequently, the service life of the sensor is prolonged, and the manufacturing and use costs are reduced.
[0035] Preferably, in the present embodiment, the sensor body 2 comprises a piezoelectric buzzer, which is provided with a breathing output line 21 and a snoring sound output line 22. The piezoelectric buzzer is a conventional electro-acoustic device with positive and negative polarities, which is simple in structure and low in price. Generally, the piezoelectric buzzer is wrapped in a plastic shell, which has a slightly larger circular hole in the center of the front surface and a slightly smaller circular hole in the center of the bottom surface. The piezoelectric buzzer can emit sound of corresponding frequency by being excited by different frequencies, and can also convert the received pressure changes into voltage changes. The piezoelectric buzzer used in the present embodiment has a plastic shell 1 with a diameter of 22 mm and a thickness of 4.5 mm.
[0036] It can be understood that, in the present scheme, the piezoelectric buzzer realizes the simultaneous detection of the breathing motion waveform and the snoring waveform through the positive piezoelectric effect. The positive piezoelectric effect refers to the phenomenon that, in some crystals, when a positive pressure is applied, the electrical resistance of the crystal changes. This phenomenon is due to the distortion of the crystal lattice structure, which causes the change of the electric charge distribution in the crystal, thereby converting mechanical energy into electrical energy. In the process of detecting the breathing motion waveform and the snoring waveform of the human body, the user wears the nasal oxygen suction hose 4 connected with the sensor. During the breathing process of the human body, part of the gas in the nasal cavity enters the nasal oxygen suction hose 4 and flows to the piezoelectric buzzer, causing the piezoelectric sheet to produce a slight deformation and thereby generating a changing voltage. This slight deformation has a certain periodicity with the change of the breathing rhythm; when the user snores, the vibration of the nasal cavity gas will be transmitted along the nasal oxygen suction hose 4 to the piezoelectric sheet. The above two signals are output after being processed by the processing circuit on the circuit board, and there is no obvious interference between the two signals. The two signals are output through a standard electroencephalogram interface plug and can be directly connected to related equipment.
[0037] Of course, in other possible embodiments, the size of the piezoelectric buzzer is not limited to the size described above. The piezoelectric buzzer is fixed to the shell 1 by the sealing sleeve 32. When a piezoelectric buzzer of different size is used, the size of the sealing sleeve 32 can be adjusted appropriately to ensure that a good airtight connection between the sealing sleeve 32 and the piezoelectric buzzer. In this way, even if the size of the piezoelectric buzzer changes, it can still work normally and achieve the expected acoustic effect, thereby ensuring that the performance of the entire device will not be affected by the change in size.
[0038] In order to ensure the stable connection of the nasal oxygen suction hose 4 and the sensor body 2, please refer to Figures 1 to 4 In the present embodiment, the connection assembly 3 is composed of an airflow interface 31 and a sealing sleeve 32. The sealing sleeve 32 is arranged inside the shell 1 and has a clamping groove for wrapping the sensor body 2 to realize the fixed installation of the sensor body 2. One end of the airflow interface 31 is connected with the sealing sleeve 32, and the other end is connected with the nasal oxygen suction hose 4.
[0039] Specifically, in some embodiments, a gas passage groove 322 is arranged inside the clamping groove of the sealing sleeve 32, and a gas flow connecting port 324 is arranged at a position corresponding to the detection surface of the sensor body 2 on one side of the gas passage groove 322. The main purpose of the gas flow connecting port 324 is to facilitate connection to the external gas flow interface 31. Through such connection, the gas flow from the nasal cavity can be effectively guided to the detection surface of the sensor body 2. The gas flow interface 31 is composed of a hose connecting port 311 and a connecting nozzle 312. One end of the hose connecting port 311 is connected to the connecting nozzle 312 through tight insertion, and the other end of the hose connecting port 311 is designed to be tightly inserted into the nasal oxygen suction hose 4. Such design can ensure the sealing between the connecting assembly 3 and the nasal oxygen suction hose 4, preventing gas leakage. The design of the entire gas flow interface 31 takes into account the stability and sealing of the connection, thereby improving the performance of the entire system.
[0040] In these components, the connection between the gas flow interface 31, the sealing sleeve 32, and the nasal oxygen suction hose 4 is achieved through a tight insertion design, which allows users to easily disassemble and reassemble to meet different usage needs and facilitate cleaning and maintenance.
[0041] Further, in some embodiments, a wire hole 321 is arranged inside the clamping groove of the sealing sleeve 32, which is used to guide the breathing output line 21 and snoring output line 22 of the piezoelectric buzzer.
[0042] Further, in some embodiments, the outer side of the sealing sleeve 32 is designed to protrude outward, forming a plurality of connecting protrusions 323. The connecting protrusions 323 are arranged to ensure that the sealing sleeve 32 can be stably installed in the corresponding position. Specifically, the connecting protrusions 323 will be in close contact with the inner surface of the shell 1, which can effectively prevent the sealing sleeve 32 from shifting or falling off during use.
[0043] Preferably, in this embodiment, the silica gel sealing sleeve 32 is made of soft silica gel material with certain elasticity, which is convenient to fit on the piezoelectric buzzer and can also provide good sealing effect.
[0044] The design of the connecting assembly 3 not only ensures the stable connection of the nasal oxygen suction hose 4 and the sensor body 2, but also allows users to easily disassemble and replace the nasal oxygen suction hose 4, facilitating the use of users in different environments. In addition, the structural design of the connecting assembly 3 ensures the good air tightness of the entire device during use, ensuring the accuracy of the detection data and the long-term stable operation of the equipment.
[0045] Please refer to Figure 1、 Figure 5 and Figure 6 In the embodiment, one side of the shell 1 is provided with an air nozzle clamping groove 101, the air flow connecting port 324 of the sealing sleeve 32 extends out through the air nozzle clamping groove 101 and is connected with the connecting air nozzle 312 of the air flow connecting piece 31, and the hose connecting port 311 at the other end of the connecting air nozzle 312 is connected with the nasal oxygen inhalation hose 4. The other side of the shell 1 is provided with a breathing output line groove 102 and a snoring sound output line groove 103, so that the breathing output line 21 and the snoring sound output line 22 of the sensor body 2 pass through the breathing output line groove 102 and the snoring sound output line groove 103 respectively, thereby connecting with external devices.
[0046] The design of the device also considers the individual needs of users, and the shell 1 is designed to be detachable. Preferably, in the embodiment, the shell 1 comprises an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are connected with each other through a clamping structure. Specifically, the connecting edge of the upper shell 11 is provided with a protruding structure, and the connecting edge of the lower shell 12 is provided with a connecting groove matched therewith, and the two are clamped and connected through the protruding structure and the connecting groove. This connection mode not only ensures the close combination between the two shells, but also enables easy disassembly and reassembly when maintenance or replacement of parts is required. The air nozzle clamping groove 101, the breathing output line groove 102 and the snoring sound output line groove 103 are all arranged at the connecting region of the upper shell 11 and the lower shell 12, so that the wires can be arranged and fixed in order, and the wires can be easily removed when the shell 1 is opened, thereby facilitating the removal of the piezoelectric buzzer and improving the convenience during use, thereby greatly reducing the work burden of medical staff.
[0047] Preferably, in the embodiment, the shell 1 has a length of 46 mm, a width of 34 mm and a thickness of 16 mm.
[0048] Please refer to Figures 1 to 7 The positive electrode of the piezoelectric buzzer is welded with the circuit board P1, and the negative electrode is welded with the circuit board P2. Before welding, the wire is first passed through the wire hole 321 of the sealing sleeve 32, and is installed with the front face towards the bottom of the sealing sleeve 32. The connecting protrusion 323 of the sealing sleeve 32 can be pressed against the shell 1. During use, the gas enters the sealing sleeve 32 through the nasal oxygen inhalation hose 4 and the air flow connecting piece 31, and then enters the small hole of the front face of the piezoelectric buzzer through the airway groove 322 and exerts pressure on the internal piezoelectric ceramic sheet. The change in air pressure in the tube caused by the user's exhalation and inhalation will cause the piezoelectric ceramic sheet to change in pressure, thereby generating a waveform signal reflecting the breathing rhythm. According to the differences in frequency and amplitude of the breathing and snoring signals, the processing circuit can separate the breathing waveform signal and the snoring signal. The circuit board is close in size to the internal size of the shell, and the circuit board and the sealing sleeve 32 are tightly installed in the shell 1 without shaking, thereby forming good air tightness.
[0049] The utility model discloses a shell 1, sensor body 2, connecting assembly 3 and nose oxygen hose 4 are set up, sensor body 2 sets up inside the shell 1, and it is connected nose oxygen hose 4 through connecting assembly 3, and the connection with human nasal cavity is realized through nose oxygen hose 4, when using, the nasal cavity gas is guided into the detection surface of sensor body 2 by nose oxygen hose 4, and the respiratory movement waveform and the snore waveform are detected through sensor body 2, can realize the simultaneous detection of the detection respiratory movement waveform and the snore movement waveform, and the material of nose oxygen hose 4 is soft and has good biocompatibility, and it is convenient to connect human nasal cavity easily, ensures that long time use also can not cause nasal cavity discomfort. This not only improves the comfort of the wearer in the sleep monitoring process, but also reduces the contact of the sensor body with the humid oral and nasal airflow, so that the sensor body 2 does not need to be cleaned and disinfected frequently, and only the nose oxygen hose 4 needs to be replaced, which can prolong the service life of the sensor, thereby reducing the manufacturing and use cost.
[0050] The breathing monitoring device is designed with exquisite design, convenient to carry, and is particularly suitable for use during sleep. The shell 1 not only ensures the durability of the device, but also does not bring additional burden to the user. In actual application, the device can monitor the breathing state of the user in real time, and analyze the respiratory movement waveform and the snore waveform through the built-in algorithm, so as to evaluate the sleep quality.
