Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a respiratory therapy device. Background Technology

[0002] Currently, negative pressure breathing therapy devices are used in clinical treatment to treat symptoms of airway obstruction such as obstructive sleep apnea and snoring. During use, the device is fixed to the subject's jaw and throat.

Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0041] The following description, in conjunction with the accompanying drawings, details a respiratory mask and ventilation therapy device provided in this application through specific embodiments and application scenarios.

[0042] Reference Figure 1 As shown, an embodiment of this application provides a respiratory therapy device, including: a collar 10; the collar 10 has a hollow main body 101, the main body 101 is volume adjustable and has a first cavity 102; the collar 10 is used to surround the neck of a subject 20, the main body 101 and at least the laryngeal region of the subject 20 form a second cavity 30; the first cavity 102 is configured to positive pressure to adjust the volume of the main body 101; the second cavity 30 is configured to negative pressure to form a negative pressure treatment zone in at least the laryngeal region of the subject 20.

[0043] Specifically, such as Figure 1 As shown, the collar 10 is used to wrap around the neck of the subject 20 and is made of at least partially flexible material, such as silicone or TPE (Thermoplastic Elastomer), which can improve the fit and sealing and wearing comfort. The collar 10 can be worn in two ways: directly through the subject 20's head to the subject 20's neck; or the collar 10 can be disassembled, placed around the subject 20's neck, and then reassembled to wrap around the neck.

[0044] The collar 10 has a hollow main body 101, which is also made of at least part of a flexible material to achieve adjustable volume. The main body 101 has a first cavity 102 inside, which can be inflated using a device such as an air pump to create positive pressure. Under this positive pressure, part of the flexible material in the main body 101 is stretched and deformed, thus achieving adjustable volume. In use, the main body 101 contacts the neck and jaw of the subject 20. By adjusting the size of the main body 101, a good fit can be achieved with different subjects 20.

[0045] The main body 101 and at least the throat region of the subject 20 form a second cavity 30. In one embodiment of this application, the main body 101 only fits against the throat region of the subject 20 to form the second cavity 30. A headband structure is used for the other parts of the collar 10, and the headband structure is connected to the main body 101 to fix the main body 101 to the throat region of the subject 20. The headband structure and the main body 101 can be connected by bonding, heat fusion, etc. The headband structure and the main body 101 can also be manufactured using an integral molding process to improve the structural strength and aesthetics of the collar 10.

[0046] In another embodiment of this application, the collar 10 is entirely hollow, and the collar 10 is the main body 101. The main body 101 surrounds the neck of the subject 20, forming a second cavity 30 around the neck of the subject 20. In this way, there is no need to set up a headband structure, and it can better fit the neck and jaw of the subject 20, improving the airtightness of the second cavity 30.

[0047] The second cavity 30 is configured to create a negative pressure treatment zone in at least the laryngeal region of the subject 20. A device such as an air pump 501 can be used to evacuate the second cavity 30 to create this negative pressure. The positive and negative pressures described above can be defined using standard atmospheric pressure. The specific extent of the negative pressure treatment zone can be determined according to the two embodiments described above. For example, if the main body 101 only fits against the laryngeal region of the subject 20, the negative pressure treatment zone is formed only in the laryngeal region of the subject 20; if the main body 101 surrounds the neck of the subject 20, the negative pressure treatment zone surrounds the neck of the subject 20, including the laryngeal region.

[0048] In this embodiment, the respiratory therapy device includes a collar 10, which has a hollow main body 101. The main body 101 is volume-adjustable and has a first cavity 102. The collar 10 is used to wrap around the neck of a subject 20, and the main body 101 and at least the throat region of the subject 20 form a second cavity 30. The first cavity 102 is configured to provide positive pressure to adjust the volume of the main body 101; the second cavity 30 is configured to provide negative pressure to form a negative pressure treatment zone in at least the throat region of the subject 20. By controlling the pressure within the first cavity 102, the volume of the main body 101 can be adjusted, adapting to different subjects 20, improving the comfort of the subject, and ensuring a good seal between the main body 101 and the neck and jaw of the subject 20, thus guaranteeing the sealing of the second cavity 30 and improving the therapeutic effect.

[0049] Optionally, refer to Figure 1 As shown, a rigid partition 103 is provided on the side of the main body 101 near the subject 20 to separate the first cavity 102 and the second cavity 30.

[0050] Specifically, such as Figure 1 As shown, when the collar 10 is worn around the neck of the subject 20, a rigid divider 103 is provided on the side of the main body 101 closest to the subject 20. The rigid divider 103 can be made of a material with high hardness and that is not easily deformed, such as PET (polyethylene terephthalate) or ABS (acrylonitrile butadiene styrene copolymer). The rigid divider 103 can be disposed inside the main body 101 or on the outer surface of the main body 101 closest to the subject 20.

[0051] When the respiratory therapy device is in use, since the first chamber 102 is under positive pressure and the second chamber 30 is under negative pressure, the rigid separator 103 allows the first chamber 102 and the second chamber 30 to operate independently. The first chamber 102, even under positive pressure, will not encroach on the space of the second chamber 30, thus avoiding any impact on the treatment effect.

[0052] On the outer surface of the main body 101 away from the subject 20, since it does not need to contact the subject 20, it can also be made of a material similar to the rigid separator 103 described above, which can prevent excessive deformation of the main body 101 from affecting the sealing effect of the second cavity 30. In this embodiment, a flexible material can be used only in the area of ​​the main body 101 that needs to contact and fit with the subject 20, while other areas are made of a material similar to the rigid separator 103 described above. When gas is introduced into the first cavity 102 to form a positive pressure, the flexible material of the main body 101 deforms, the volume of the main body 101 increases, thereby forming a good sealing fit with the subject 20.

[0053] Optionally, the area of ​​the main body 101 that fits against the subject 20 is made of a flexible material.

[0054] Specifically, the main body 101 is provided with a rigid partition 103 only between the first cavity 102 and the second cavity 30, and other areas can be made of flexible materials. In particular, the area of ​​the main body 101 used to fit with the subject 20 is made of flexible materials, such as silicone or TPE, which can ensure good fit between the main body 101 and the subject 20, improve the sealing of the second cavity 30, and thus improve the treatment effect.

[0055] Optionally, refer to Figure 1 As shown, the respiratory therapy device also includes a first sensor 40; the first sensor 40 is distributed in the area of ​​the main body 101 that is in contact with the subject 20, and is used to detect the pressure in the area where the main body 101 is in contact with the subject 20.

[0056] Specifically, such as Figure 1 As shown, the first sensor 40 can be a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. The first sensor 40 is distributed in the area of ​​the main body 101 that is in contact with the subject 20, thereby detecting the pressure in the area where the main body 101 and the subject 20 are in contact. Based on the pressure data from the first sensor 40, the control module can calculate a suitable pressure value within the first cavity 102, ensuring the sealing of the second cavity 30 while preventing excessive pressure in the first cavity 102 from affecting the subject 20.

[0057] In this embodiment, the area where the main body 101 fits against the subject 20 is made of silicone material. Flexible pressure sensors are evenly distributed on the silicone material. The flexible pressure sensors can record stress and resistance changes according to the body posture of the subject 20 and detect human physiological electrical signals. The resistance value of the flexible pressure sensors represents the pressure between the silicone material and the subject 20.

[0058] Optionally, refer to Figure 1As shown, the respiratory therapy device also includes an air pump assembly 50; the air pump assembly 50 is connected to the first cavity 102 and the second cavity 30 respectively, and is used to adjust the air pressure of the first cavity 102 or the second cavity 30.

[0059] Specifically, such as Figure 1 As shown, the first cavity 102 and the second cavity 30 utilize an air pump assembly 50 to regulate their internal air pressure. The air pump assembly 50 may include an air pump 501, a flexible ventilation tube, etc. The size and power of the air pump 501 can be selected according to actual usage requirements, and this embodiment does not limit this. The first cavity 102 and the second cavity 30 may share a single air pump 501, or they may be controlled by different air pumps 501.

[0060] Optionally, refer to Figure 1 As shown, the air pump assembly 50 includes an air pump 501 and a three-way valve 502; the three-way valve 502 has a first port, a second port and a third port, the first port is connected to the air pump 501, the second port is connected to the first cavity 102 and the third port is connected to the second cavity 30; the three-way valve 502 is used to control the air passage between the first port and the second port or between the first port and the third port.

[0061] Specifically, such as Figure 1 As shown, to reduce the number of components, the first cavity 102 and the second cavity 30 can share a single air pump 501, which is switched using a three-way valve 502. The three-way valve 502 has a first port, a second port, and a third port. The first port is connected to the air pump 501, specifically through a vent pipe; the second port is connected to the first cavity 102, and the third port is connected to the second cavity 30, also through a vent pipe.

[0062] When the respiratory therapy device is in use, if it is necessary to ventilate the first cavity 102, the switching device in the three-way valve 502 can be controlled to open the air passage between the first port and the second port, so that the gas enters the first cavity 102 through the first port and the second port, so as to form a positive pressure in the first cavity 102, the volume of the main body 101 expands, and achieves a good fit with the subject 20.

[0063] If it is necessary to evacuate air from the second chamber 30, the switching device within the three-way valve 502 can be controlled to open the air passage between the first and third ports. This allows the air pump 501 to extract air from the second chamber 30 through the third and first ports, creating a negative pressure within the second chamber 30. This stretches the collapsed airway of the subject 20, ensuring unobstructed breathing. The negative pressure value of the second chamber 30 can be preset at the factory or adjusted according to the specific circumstances of each subject 20.

[0064] The switching device inside the three-way valve 502 can be manually controlled, for example, by setting a control button or a switching switch on the outside of the three-way valve 502; or it can be automatically controlled by a control chip to make the respiratory therapy device more intelligent.

[0065] Optionally, refer to Figure 1 As shown, the main body 101 is provided with a first gas passage 60. One end of the first gas passage 60 is connected to the second cavity 30, and the other end of the first gas passage 60 is connected to the outside. A first valve body 70 is provided inside the first gas passage 60. When the pressure in the second cavity 30 is lower than the first pressure threshold, the first valve body 70 is in the open state, so that the first gas passage 60 is in the conductive state.

[0066] Specifically, such as Figure 1 As shown in one embodiment of this application, when the respiratory therapy device is used, a negative pressure needs to be formed in the second cavity 30. If the negative pressure is too high, i.e., too low, it may cause discomfort to the subject 20. Here, the negative pressure value is the absolute value of the pressure inside the second cavity 30. Therefore, a first gas channel 60 is provided on the main body 101. The first gas channel 60 can be a pre-formed perforation structure during the fabrication of the main body 101, or it can be a separately formed perforation structure on the main body 101. The cross-sectional shape of the first gas channel 60 can be circular, elliptical, etc., and the cross-section can be a variable cross-section or a uniform cross-section. One end of the first gas channel 60 is connected to the second cavity 30, and the other end is connected to the outside. The second cavity 30 can be ventilated to the outside through the first gas channel 60.

[0067] A first valve body 70 is provided within the first gas channel 60. The first valve body 70 has an open state and a closed state. When the pressure within the second cavity 30 is at a relatively comfortable and normal level for the subject 20, the first valve body 70 is in the closed state, and the first gas channel 60 is also in the closed state. Therefore, the second cavity 30 cannot communicate with the outside world through the first gas channel 60, and the second cavity 30 is in a relatively sealed state. When the pressure within the second cavity 30 is lower than a first pressure threshold, which can be determined based on the subject 20's own condition, the subject 20 may experience symptoms such as physical discomfort when the pressure is lower than this first pressure threshold. At this time, the first valve body 70 is in the open state, and the first gas channel 60 is also in the open state. Therefore, the second cavity 30 can communicate with the outside world through the first gas channel 60, allowing outside air to enter the second cavity 30 through the first gas channel 60 to increase the pressure within the second cavity 30, thus allowing the subject 20 to be in a comfortable wearing mode. When outside air enters the second chamber 30, the pressure inside the second chamber 30 will increase. When the pressure rises to the first pressure threshold, the first valve body 70 will be closed again, and the first gas passage 60 will also be closed. Thus, the second chamber 30 cannot communicate with the outside through the first gas passage 60, and the second chamber 30 is in a relatively sealed state.

[0068] Optionally, refer to Figure 1 As shown, a second gas passage 80 is provided between the first cavity 102 and the second cavity 30. One end of the second gas passage 80 is connected to the first cavity 102, and the other end of the second gas passage 80 is connected to the second cavity 30. A second valve body 90 is provided inside the second gas passage 80. When the pressure in the second cavity 30 is lower than the second pressure threshold, the second valve body 90 is in the open state, so that the second gas passage 80 is in the conductive state.

[0069] Specifically, such as Figure 1 As shown, in another embodiment of this application, to avoid excessive negative pressure in the second cavity 30 causing discomfort to the subject 20, a second gas channel 80 can be provided between the first cavity 102 and the second cavity 30. The second gas channel 80 can be a pre-formed perforation structure during the fabrication of the main body 101, or it can be a separately formed perforation structure in the main body 101. The cross-sectional shape of the second gas channel 80 can be circular, elliptical, etc., and the cross-section can be a variable cross-section or a uniform cross-section. One end of the second gas channel 80 is connected to the first cavity 102, and the other end is connected to the second cavity 30, allowing ventilation between the first cavity 102 and the second cavity 30.

[0070] A second valve body 90 is provided within the second gas channel 80. The second valve body 90 has an open state and a closed state. When the pressure within the second cavity 30 is at a relatively comfortable and normal level for the subject 20, the second valve body 90 is in the closed state, and the second gas channel 80 is also in the closed state. Therefore, the second cavity 30 cannot communicate with the first cavity 102 through the second gas channel 80, and both the first cavity 102 and the second cavity 30 are in a relatively sealed state. When the pressure within the second cavity 30 is lower than a second pressure threshold, the second pressure threshold can be determined based on the subject 20's own condition. The first pressure threshold and the second pressure threshold can be the same or different. When the pressure inside the second cavity 30 is lower than the second pressure threshold, the subject 20 may experience symptoms such as discomfort. At this time, the second valve 90 and the second gas channel 80 are open, allowing the second cavity 30 to connect with the first cavity 102 via the second gas channel 80. This allows gas from the first cavity 102 to enter the second cavity 30 through the second gas channel 80, increasing the pressure inside the second cavity 30 and providing a comfortable wearing experience for the subject 20. Once the gas from the first cavity 102 enters the second cavity 30, the pressure inside the second cavity 30 increases. When this pressure reaches the second pressure threshold, the second valve 90 closes again, and the second gas channel 80 also closes. This prevents the second cavity 30 from connecting with the first cavity 102 via the second gas channel 80, leaving the second cavity 30 in a relatively sealed state.

[0071] Optionally, the respiratory therapy device further includes a control module; the control module is electrically connected to the first sensor 40 and the air pump assembly 50 respectively; the control module is used to acquire pressure data from the first sensor 40 and control the air pump assembly 50.

[0072] Specifically, the control module may include a main control chip, control circuitry, etc. The control module is electrically connected to the first sensor 40 and the air pump assembly 50, respectively. The control module can control the air pump assembly 50 based on the pressure data from the first sensor 40. For example, the control module first controls the air pump assembly 50 to inflate the first cavity 102. When the main body 101 comes into contact with the subject 20, the first sensor 40 on the main body 101 will feed back pressure data to the control module. The control module then determines whether to continue inflating the first cavity 102 based on the pressure data. The control module can also automatically control the switching device within the three-way valve 502 to switch the air pump 501 between the first cavity 102 and the second cavity 30. By setting up the control module, the inflation and deflation processes of the first cavity 102 and the second cavity 30 can be automatically controlled, and the automatic switching of the air pump 501 can also be achieved, greatly improving the intelligence level of the respiratory therapy device.

[0073] Optionally, a second sensor is provided inside the first cavity 102; the second sensor is electrically connected to the control module, which is used to acquire the pressure data of the second sensor and control the air pump assembly 50.

[0074] Specifically, the second sensor is disposed within the first cavity 102 and can feed back the pressure within the first cavity 102 to the control module in real time. The second sensor can be a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. The second sensor can be connected to the cavity wall of the first cavity 102, and the specific connection method can be adhesive, snap-fit, etc.

[0075] The control module can simultaneously acquire pressure data from the first sensor 40 and the second sensor. Through comprehensive analysis and calculation, it can derive the optimal control scheme to control the operation of the air pump assembly 50, thereby achieving precise adjustment of the air pressure in the first cavity 102.

[0076] Optionally, a third sensor is provided in the second cavity 30; the third sensor is electrically connected to the control module, which is used to acquire the pressure data of the third sensor and control the air pump assembly 50.

[0077] Specifically, a third sensor is installed inside the second cavity 30, which can feed back the pressure inside the second cavity 30 to the control module in real time. The third sensor can be a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. The third sensor can be connected to the outer surface of the main body 101 near the second cavity 30, and the specific connection method can be adhesive, snap-fit, etc.

[0078] The control module can control the air pump assembly 50 to evacuate the second chamber 30 based on the pressure data from the third sensor. Since there is slight interference between the first chamber 102 and the second chamber 30, the control module can simultaneously acquire pressure data from the first sensor 40, the second sensor, and the third sensor. Through comprehensive analysis and calculation, it can derive the optimal control scheme to control the air pump assembly 50, thereby achieving precise adjustment of the air pressure within the first chamber 102 and the second chamber 30.

[0079] Optionally, refer to Figure 2 As shown, the respiratory therapy device also includes a positive pressure ventilation assessment device 100; the positive pressure ventilation assessment device 100 is electrically connected to the control module; the control module is used to acquire the status parameters of the positive pressure ventilation assessment device 100 and control the air pump assembly 50.

[0080] Specifically, such as Figure 2As shown, the negative pressure parameters required for the second cavity 30 vary depending on the different subjects 20 and the different treatment stages of the same subject 20. To improve the treatment effect and the comfort of the subject 20, a positive pressure ventilation assessment device 100 can be set up to detect the ventilation pressure in the airway of the subject 20 and obtain the appropriate negative pressure parameters required for the second cavity 30 based on the ventilation pressure data. In use, the positive pressure ventilation assessment device 100 is connected to the mouth and / or nose of the subject 20 and introduces gas into the airway of the subject 20. The ventilation pressure data in the airway of the subject 20 can be obtained using the pressure sensor on the positive pressure ventilation assessment device 100.

[0081] In one embodiment of this application, the ventilation pressure data of the positive pressure ventilation assessment device 100 can be matched with the negative pressure parameters required by the second chamber 30 through manual calculation, and then the negative pressure parameters of the respiratory therapy device can be modified. In another embodiment of this application, the positive pressure ventilation assessment device 100 can be directly electrically connected to the control module.
