TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a monitoring device for keeping the airway unobstructed and a use method thereof. BACKGROUND

[0002] In clinical treatment, patients in coma, patients who have not fully woken up after anesthesia, patients with swallowing dysfunction caused by nervous system diseases, etc., often have tongue root falling back due to muscle relaxation, mouth breathing, etc. Tongue root falling back will block the airway, leading to insufficient ventilation and hypoxia in patients, and even causing suffocation in severe cases, endangering life. The commonly used airway unobstructed maintenance methods in the clinic include placing oropharyngeal airway tube, nasopharyngeal airway tube, etc., but such devices are highly invasive, and long-term use can cause oral mucosa damage and infection, and cannot monitor the occurrence of tongue root falling back in real time. In the prior art, although some anti-snoring electronic products use attached sensors to monitor chin activity, such products are only suitable for mild respiratory intervention of healthy people and lack the function of fixing and timely alarming for tongue root falling back in combination with the airway support needs of clinical patients. Therefore, it is necessary to design a new technical solution to solve the problem. SUMMARY

[0003] The present application aims to provide a monitoring device for keeping the airway unobstructed and a use method thereof, which solves the problems raised in the background art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solution: a monitoring device for keeping the airway unobstructed, comprising an elastic band, the upper side of the elastic band is provided with a storage assembly for storing the elastic band, the storage assembly is connected with a driving assembly for driving the storage assembly; The inner cavity of the elastic band is fixedly installed with a cotton pad, the inner cavity of the cotton pad is installed with a plurality of evenly distributed air bag strips, the inner surface of the cotton pad is fixedly installed with an attached sensor in the middle, the storage assembly is further installed with a micro air pump, the output end of the micro air pump is communicated with a catheter, the catheter has a plurality of branches, and each branch is respectively communicated with a corresponding air bag strip.

[0005] By adopting the above technical solution, in actual use, the elastic bandage is first placed over the patient's head, and the cotton pad is placed under the patient's chin. Then, the elastic bandage is tightened using the storage component to secure it against the chin, thus helping to prevent tongue retraction. During actual use, the pressure is monitored by an attached sensor. When the pressure value fed back to the monitoring computer by the attached sensor exceeds the threshold, a buzzer is automatically activated to alarm staff, alerting them to the danger of tongue retraction and allowing staff to take timely action to prevent dangerous situations. Furthermore, gas is generated by a micro air pump and introduced into the airbag strip, causing the airbag strip to inflate. This improves the fit when the chin is fitted and limited, further reducing the risk of tongue retraction and ensuring the fit between the attached sensor and the chin, thereby ensuring the accuracy of monitoring.

[0006] In a preferred embodiment of the present invention, the inner side walls of the elastic band are provided with mesh holes, the inner side walls of the elastic band are sandwich structures, and hollow airbags are installed on the inner side of the elastic band. The inner side walls of the hollow airbags are provided with holes, and the conduit also includes two branches, which are respectively connected to two hollow airbags.

[0007] By adopting the above technical solution, a solenoid valve is installed at the connection between the hollow airbag and the catheter branch to control the gas entry. When ventilation is needed, the gas enters the hollow airbag, is then discharged through the holes, and passes through the mesh to act on the patient's face, thereby increasing breathability and improving the effect of use.

[0008] In a preferred embodiment of the present invention, the storage component includes a fixed box with a strip-shaped hole at the bottom. A scroll is rotatably mounted inside the fixed box. One end of the scroll passes through the fixed box and is connected to a drive component. One end of the elastic strap is fixedly connected to the bottom of the fixed box, and the other end movably passes through the strip-shaped hole and is fixedly wrapped around the outer wall of the scroll. The micro air pump is fixedly mounted on the top of the fixed box.

[0009] By adopting the above technical solution, the drive component can drive the roller to rotate, thereby releasing or tightening the elastic bandage, which facilitates the adjustment of tightness and can be used by different patients, thus improving adaptability.

[0010] In a preferred embodiment of the present invention, a guide roller is rotatably mounted on one side wall of the inner cavity of the strip-shaped hole.

[0011] In a preferred embodiment of the present invention, the drive assembly includes a fixed housing, which is fixedly installed on one side wall of a fixed box. A rotating shaft is rotatably installed on the inner wall of the fixed housing. The rotating shaft movably passes through the fixed housing and is fixedly connected to one end of a reel. A worm gear is fixedly fitted on the outer wall of the rotating shaft. A worm is meshed on the outer wall of the worm gear. One end of the worm is rotatably connected to the inner wall of the fixed housing. A servo motor is fixedly installed on one side of the fixed housing. The drive shaft of the servo motor movably passes through the fixed housing and is fixedly connected to the other end of the worm.

[0012] By adopting the above technical solution, the servo motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, thereby driving the rotating shaft to rotate, and indirectly driving the reel to rotate, thus realizing the winding or unwinding of the elastic strap.

[0013] In a preferred embodiment of the present invention, each branch of the conduit is fitted with a suitable solenoid valve.

[0014] In a preferred embodiment of the present invention, the surface of the cotton pad is provided with a plurality of evenly distributed strip grooves.

[0015] The present invention also relates to a method of using a monitoring device for maintaining airway patency, comprising the following steps: Step 1: First, place the elastic bandage on the patient's head and position the cotton pad under the patient's chin. The servo motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, thereby driving the rotating shaft to rotate and indirectly driving the roll to rotate. This allows the elastic bandage to be rolled up and pressed tightly against the chin, which helps to prevent the tongue from sticking back. A micro air pump generates gas and introduces it into the airbag strip, which allows the airbag strip to expand, thereby improving the fit when the chin is fitted and limited. Step 2: The pressure is monitored by an attached sensor. When the pressure value fed back to the monitoring computer by the attached sensor exceeds the threshold, the buzzer will be automatically activated to sound an alarm, alerting staff that the patient has a dangerous situation of tongue suffocation.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses an elastic band to cover the patient's head and jaw, thereby applying a certain amount of force to the jaw to help prevent the tongue from becoming posterior. It also uses an attached sensor to monitor the pressure at the location of the posterior tongue, so that when posterior tongue occurs, a signal can be fed back to the monitoring computer in a timely manner, thereby activating the alarm module to sound an alarm. Gas is generated by a micro air pump and introduced into the airbag strip, which allows the airbag strip to expand. This improves the fit when the mandible is fitted and limited, which helps to further reduce the risk of tongue base retraction and also ensures the fit between the attached sensor and the mandible, thus helping to ensure the accuracy of monitoring. The gas generated by the miniature air pump can be introduced into the inner cavity of the hollow airbag, then discharged through the holes on the inner wall of the airbag strip and through the mesh, so that it can be applied to the patient's face, thereby increasing breathability and improving the effect of use. The drive component can rotate the roller, thereby enabling the elastic straps to be stored or released, and thus adjusting the length of the elastic straps to improve adaptability.

[0019] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The model numbers of the electrical appliances provided in this invention are for reference only, and different models of electrical appliances with the same function can be replaced according to actual usage.

[0022] Please see Figures 1-6 The present invention provides a technical solution: a monitoring device for maintaining airway patency, including an elastic strap 1, a storage component is provided on the upper side of the elastic strap 1 for storing the elastic strap 1, and a driving component is connected to the storage component for driving the storage component. A cotton pad 11 is fixedly installed on the lower side of the inner cavity of the elastic strap 1. Multiple evenly distributed airbag strips 13 are installed in the inner cavity of the cotton pad 11. An adhesive sensor 14 is fixedly installed in the middle of the inner surface of the cotton pad 11. A miniature air pump 15 is also installed on the storage assembly. The output end of the miniature air pump 15 is connected to a conduit 16. The conduit 16 has multiple branches, and each branch is connected to the corresponding airbag strip 13.

[0023] It should be noted that the signal output terminal of the attached sensor 14 is connected to the signal input terminal of the monitoring computer. The output terminal of the monitoring computer is connected to an alarm module, which is a buzzer. When the pressure value fed back to the monitoring computer by the attached sensor 14 exceeds the threshold, the buzzer can be automatically activated to sound an alarm, alerting staff that the patient has a dangerous situation of tongue suffocation.

[0024] It should be understood that in actual use, the elastic bandage 1 is first placed on the patient's head, and the cotton pad 11 is placed on the patient's chin. Then, the elastic bandage 1 is tightened using the storage component to secure it against the chin, thus helping to prevent the tongue from sticking back. During actual use, the pressure is monitored by the attached sensor 14. When the pressure value fed back to the monitoring computer by the attached sensor 14 exceeds the threshold, the buzzer will automatically be activated to alarm the staff, alerting them to the danger of the patient's tongue sticking back, allowing the staff to take timely action to avoid danger. Furthermore, the micro air pump 15 generates gas and introduces it into the airbag strip 13, causing the airbag strip 13 to expand. This improves the fit when the chin is fitted and limited, further reducing the risk of tongue sticking back and ensuring the fit between the attached sensor and the chin, thereby ensuring the accuracy of the monitoring.

[0025] Furthermore, each branch of the conduit 16 is equipped with a suitable solenoid valve, which allows for individual inflation of each airbag strip 13.

[0026] Furthermore, the surface of the cotton pad 11 is provided with multiple evenly distributed strip grooves 12. The arrangement of the strip grooves 12 can increase the air circulation effect, thereby improving comfort.

[0027] like Figure 1 and 2 As shown; the inner walls of the elastic band 1 are provided with mesh holes 17. The inner walls of the elastic band 1 are sandwiched structures, and hollow airbag bands 18 are installed on the inner side. Holes are provided on the inner side walls of the hollow airbag bands 18. The conduit 16 also includes two branches, which are connected to two hollow airbag bands 18 respectively. It should be understood that a solenoid valve is installed at the branch connection of the hollow airbag belt 18 and the conduit 16 to control the gas entry. When ventilation is required, the gas enters the hollow airbag belt 18, is then discharged through the holes, and passes through the mesh 17 to act on the patient's face, thereby increasing breathability and improving the effect of use.

[0028] like Figure 1 and 4 As shown; the storage component includes a fixed box 2, with a strip hole 22 at the bottom of the fixed box 2, and a scroll 21 rotatably mounted inside the fixed box 2. One end of the scroll 21 passes through the fixed box 2 and is connected to the drive component. One end of the elastic strap 1 is fixedly connected to the bottom of the fixed box 2, and the other end movably passes through the strip hole 22 and is fixedly wrapped around the outer wall of the scroll 21. A miniature air pump 15 is fixedly mounted on the top of the fixed box 2. It should be understood that the drive component can drive the roller 21 to rotate, thereby releasing or tightening the elastic band 1, thus facilitating the adjustment of tightness and adapting it to different patients, thereby improving adaptability.

[0029] Furthermore, a guide roller 23 is rotatably mounted on one side wall of the inner cavity of the strip hole 22. The guide roller 23 is provided to guide the elastic strap 1, thereby preventing wear on the elastic strap 1.

[0030] like Figure 1 and 5 As shown; the drive assembly includes a fixed housing 3, which is fixedly installed on one side wall of the fixed box 2. A rotating shaft 31 is rotatably installed on the inner wall of the fixed housing 3. The rotating shaft 31 movably passes through the fixed housing 3 and is fixedly connected to one end of the scroll 21. A worm gear 32 is fixedly fitted on the outer wall of the rotating shaft 31. A worm 33 meshes with the outer wall of the worm gear 32. One end of the worm 33 is rotatably connected to the inner wall of the fixed housing 3. A servo motor 34 is fixedly installed on one side of the fixed housing 3. The drive shaft of the servo motor 34 movably passes through the fixed housing 3 and is fixedly connected to the other end of the worm 33.

[0031] It should be understood that in actual use, the servo motor 34 drives the worm gear 33 to rotate, which in turn drives the worm wheel 32 to rotate, thereby driving the rotating shaft 31 to rotate, which in turn drives the winding shaft 21 to rotate, thereby enabling the elastic strap 1 to be wound up or released.

[0032] A method for using a monitoring device to maintain airway patency, comprising the following specific steps: Step 1: First, place the elastic bandage 1 on the patient's head and position the cotton pad 11 under the patient's chin. The servo motor 34 drives the worm gear 33 to rotate, which in turn drives the worm wheel 32 to rotate, thereby driving the rotating shaft 31 to rotate, which in turn drives the roller 21 to rotate, thus rolling up the elastic bandage 1 and securing it against the chin. This helps to prevent the tongue from sticking back. The micro air pump 15 generates gas and introduces it into the airbag strip 13, which inflates the airbag strip 13, thereby improving the fit when fitting and limiting the chin. Step 2: The pressure is monitored by the attached sensor 14. When the pressure value fed back to the monitoring computer by the attached sensor 14 is greater than the threshold, the buzzer can be automatically activated to sound an alarm, alerting staff that the patient has a dangerous situation of tongue suffocation.

[0033] Furthermore, the components included in the monitoring device for maintaining airway patency and its usage method of the present invention are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of the device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching monitoring computer and power supply, are connected by wires. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a well-known technology in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
