Description

Technical Field

[0001] The present invention relates to the technical field of oral moistening medical devices, in particular to a deformable oral moistening component and a mask. Background Art

[0002] Mechanical ventilation, a process in which a mechanical device replaces or assists the work of respiratory muscles, is a supportive therapy used to maintain a patient's respiratory function and is widely used in critical care. Orotracheal intubated patients are forced to change their normal breathing pattern, unable to close their mouths and unable to consume food or water. As mechanical ventilation progresses, moisture evaporates from the oral mucosa, leading to symptoms of dry mouth and thirst.

[0003] In clinical practice, a spray bottle is often used to spray water mist into the patient's mouth to relieve thirst. However, in practice, the sprayed water mist often spreads to the back wall of the throat, irritating the throat area, which can easily trigger the patient's violent coughing and increase the risk of endotracheal tube displacement or even dislocation.

[0004] Therefore, during the oral moistening operation for patients with endotracheal intubation, how to avoid irritation to the throat area after the water mist is sprayed is a technical problem that needs to be solved urgently in the existing technology. Summary of the Invention

[0005] The purpose of the present invention is to provide a deformable mouth moistening component and a mask to address the problem in the prior art of using a spray bottle to spray water mist into the patient's mouth to relieve the patient's thirst symptoms.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. The deformable oral moistening component described in the present invention has the upper supporting component and the lower supporting component arranged on the inner side of the cover plate. In actual use, the upper airbag and the lower airbag are expanded to drive the upper bite plate and the lower bite plate to slide toward each other, so that the patient's oral cavity can be expanded, and the spray can be more evenly diffused during the moistening operation, thereby improving the moistening effect of the oral cavity; further, the annular nozzle is arranged to be connected to the endotracheal tube and extend to the root of the tongue, and cooperates with the atomization spray directed toward the cover plate, so that the water mist accurately covers the oral mucosa without The cover plate touches the back wall of the throat, avoiding irritation to the throat area and significantly reducing the risk of displacement and dislodgment of the endotracheal tube due to coughing. Furthermore, the upper supporting member and the lower supporting member are arranged on the inner side of the cover plate to directly abut against the teeth, thereby avoiding the "tube biting" phenomenon during endotracheal intubation. On the one hand, it ensures the normality of the endotracheal tube, and on the other hand, it also reduces the risk of damage to the endotracheal tube during indwelling. Furthermore, in this embodiment, the cover plate and the binding strap can cooperate to fix the endotracheal tube, thereby improving the practicality of the present invention in actual application.

[0023] 2. The deformable oral moistening assembly of the present invention comprises the isolation film and the drainage trough provided on the nozzle. During the suction operation of removing oral secretions from a patient, the infusion tube is used to push the nozzle downward along the endotracheal tube until the end of the drainage trough reaches the epiglottis of the human body. The end of the isolation film is then connected to a suction pump. Under the action of negative pressure suction, secretions accumulated between the patient's tongue root and the posterior pharyngeal wall enter the suction channel through the drainage hole and are discharged from the fitting gap of the isolation film, thereby avoiding the accumulation of secretions in the oral cavity and reducing the risk of aspiration and infection.

[0024] Further, in this embodiment, after the end of the chute plate reaches the epiglottis of the human body, gas is injected into the sealing bladder through the liquid filling channel to make it expand. At this time, on the one hand, the sealing bladder can block the airway at the epiglottis of the human body, prevent secretions from flowing into the trachea, and reduce the risk of aspiration; on the other hand, after the sealing bladder expands, it abuts against the outer wall of the tracheal intubation to generate a reaction force, driving the end of the drainage chute plate to deflect towards the inner wall of the airway. Eventually, the end of the drainage chute plate can closely adhere to the mucosa of the airway posterior wall, so that the secretions gathered in the airway posterior wall area can be aspirated, improving the clearance effect of the secretions, and further reducing the risk of aspiration and infection of the patient. At the same time, in this embodiment, after the sealing bladder expands, the end of the drainage chute plate is separated from the tracheal intubation, and the liquid guiding holes provided on the inner wall of the drainage chute plate can be more fully exposed, improving the smoothness of the secretions entering the suction channel; and, the end of the drainage chute plate abuts against the outer wall of the tracheal intubation, and at this time, an angle is formed between the drainage chute plate and the airway posterior wall surface, avoiding the risk of the liquid guiding holes provided on the outer wall of the drainage chute plate adsorbing the mucosa of the airway posterior wall and causing mucosal damage.

[0025] Furthermore, when the sealing bladder is in an expanded state, the infusion tube is pulled to drive the nozzle and the drainage chute plate to slide along the tracheal intubation. During this process, the secretions adhering to the surface of the tracheal intubation can fall off and gather in the groove of the drainage chute plate, and then the secretions enter the suction channel through the liquid guiding holes provided on the inner wall of the drainage chute plate and are aspirated, thus keeping the tracheal intubation clean and reducing the risk of infection caused by the retention of secretions in the airway after tracheal extubation.

[0026] Moreover, in this embodiment, by using the appropriate extrusion force exerted on the epiglottic tissue after the sealing bladder expands, the secretions hidden in the anatomical gaps such as the epiglottic vallecula and pyriform sinus can be promoted to flow out, thereby further improving the clearance effect of the secretions.

[0040] Example 1: As Figure 1 and Figure 2 shown, a deformable oral moistening component according to the present invention includes a shielding cover plate 1 and a strap 2. The shielding cover plate 1 is used to cover the lips of a human body. A through hole 3 is provided on the shielding cover plate 1, and an endotracheal tube can pass through the through hole 3. The strap 2 is connected to the left and right sides of the shielding cover plate 1, and the strap 2 is used to fix the shielding cover plate 1 on the head of a human body;

[0041] On one side of the shielding cover plate 1 that contacts the lips of a human body, an upper propping component 4 and a lower propping component 5 are provided. The upper propping component 4 includes an upper bite plate 6, an upper bearing plate 7 and an upper airbag 8. The upper airbag 8 is arranged between the upper bite plate 6 and the upper bearing plate 7, and the upper bite plate 6 is used to abut against the upper row of teeth of a human body. The lower propping component 5 includes a lower bite plate 9, a lower bearing plate 10 and a lower airbag 11. The lower airbag 11 is arranged between the lower bite plate 9 and the lower bearing plate 10, and the lower bite plate 9 is used to abut against the lower row of teeth of a human body. The upper bite plate 6 and the lower bite plate 9 are in a slidable connection and cooperation with the shielding cover plate 1. When the upper airbag 8 and the lower airbag 11 expand, they can respectively push the upper bite plate 6 and the lower bite plate 9 to slide in the vertical direction;

[0042] The component further includes a spraying component 12. The spraying component 12 includes a nozzle 13 and an infusion tube 14. One end of the infusion tube 14 is connected to the shielding cover plate 1, and the other end extends to the root of the tongue in the oral cavity of a human body. The infusion tube 14 is used to convey a moistening liquid to the nozzle 13. The nozzle 13 is arranged in a circular ring structure, and the nozzle 13 is sleeved on the endotracheal tube. The water mist ejected from the nozzle 13 is directed towards the shielding cover plate 1.

[0043] Adopting a deformable oral moistening component according to the present invention, the upper supporting component 4 and the lower supporting component 5 are arranged inside the cover plate 1. In actual use, the upper airbag 8 and the lower airbag 11 are inflated to drive the upper bite plate 6 and the lower bite plate 9 to slide towards each other, enabling the patient's oral cavity to form an expanded state. Thus, during the moistening operation, the spray can disperse more evenly, improving the effect of oral moistening. Further, an annular nozzle 13 is sleeved on the tracheal intubation and extends to the root of the tongue. With the atomizing spray directed towards the cover plate 1, the water mist precisely covers the oral mucosa without touching the posterior wall of the pharynx, avoiding irritation to the pharyngeal area and significantly reducing the risk of tracheal intubation displacement and removal caused by coughing. Furthermore, the upper supporting component 4 and the lower supporting component 5 are arranged inside the cover plate 1 and directly abut against the teeth, avoiding the phenomenon of "biting the tube" during tracheal intubation. On the one hand, it ensures the patency of the tracheal intubation, and on the other hand, it also reduces the risk of damage during the indwelling period of the tracheal intubation. Moreover, in this embodiment, the cover plate 1 and the strap 2 can be used together to fix the tracheal intubation, improving the practicality of the present invention in actual application.

[0044] Specifically, in actual use of the present invention, first use an oral opener to open the patient's oral cavity; then sleeve the nozzle 13 on the outer wall of the tracheal intubation, align the through hole 3 of the cover plate 1 with the tracheal intubation in the patient's oral cavity, and slowly push it along the outer wall of the intubation so that the upper supporting component 4 and the lower supporting component 5 extend into the patient's oral cavity; pass the strap 2 around the back of the patient's head and adjust the tightness through a magic tape or elastic buckle to ensure that the cover plate 1 is closely fitted with the patient's lips; after completion, slowly inflate the upper airbag 8 and the lower airbag 11 through an external air pump to drive the upper bite plate 6 to slide upward and the lower bite plate 9 to slide downward until the upper bite plate 6 and the lower bite plate 9 tightly abut against the patient's teeth, and then remove the oral opener. At this time, the patient's oral cavity can remain in an open state.

[0045] During the operation of oral moistening, inject sterile mint water into the infusion tube 14 through the joint arranged on the cover plate 1; during the spraying process, an intermittent short-pulse mode is adopted, with the single injection time ≤ 3 seconds and the total amount of single spray ≤ 2 ml; after moistening is completed, release the air in the upper airbag 8 and the lower airbag 11 to close the patient's oral cavity.

[0046] As a preferred implementation manner, on the basis of the above method, further, a limiting channel 15 is arranged inside the upper bearing plate 7 or the lower bearing plate 10, the infusion tube 14 penetrates into the limiting channel 15, and the infusion tube 14 can slide in the limiting channel 15.

[0047] In this embodiment, the infusion tube 14 and the cover plate 1 are set to be in a sliding connection and cooperation. During the actual wetting operation, the infusion tube 14 is used to drive the nozzle 13 to slide along the tracheal intubation tube, so as to change the position of the nozzle 13 in the patient's oral cavity. In this way, precise wetting of different positions in the oral cavity can be achieved, improving the wetting effect and the practicality of the present invention.

[0048] Embodiment 2: As Figures 1 to 4 shown, for a deformable oral cavity wetting component of the present invention, on the basis of the above method, further, an isolation film 16 is connected to the nozzle 13. The isolation film 16 is set to have a bilateral structure. The isolation film 16 extends from the through hole 3 to the outside. The isolation film is used to cover the tracheal intubation tube;

[0049] A drainage groove plate 17 is also connected to the nozzle 13. The drainage groove plate 17 extends in a direction away from the spray. The cross-section of the drainage groove plate 17 is set to be an arc structure. An aspiration channel 18 and a liquid filling channel 19 are arranged inside the drainage groove plate 17. The liquid filling channel 19 is communicated with the infusion tube 14. The aspiration channel 18 is communicated with the isolation film 16. Liquid guiding holes 20 communicated with the aspiration channel 18 are also arranged on the inner wall and the outer wall of the drainage groove plate 17. The liquid guiding holes 20 are arranged on one side of the end of the drainage groove plate 17. The infusion tube 14 is set to be a double-chamber structure. One chamber is used to convey wetting liquid to the nozzle 13, and the other chamber is communicated with the liquid filling channel 19;

[0050] A blocking capsule 21 communicated with the liquid filling channel 19 is also arranged on the inner wall of the drainage groove plate 17. The blocking capsule 21 is arranged at the end of the drainage groove plate 17. The blocking capsule 21 abuts against the tracheal intubation tube in an inflated state, so that the end of the drainage groove plate 17 can be in contact with the airway mucosa of the human body; and the blocking capsule 21 can block the airway at the epiglottis part of the human body in an inflated state.

[0051] In this embodiment, it is considered that during the indwelling period of the tracheal intubation tube, the secretions in the patient's oral cavity flow backward to the back of the throat due to gravity. However, due to the obstruction of swallowing by the intubation tube, liquids and mucus accumulate between the root of the tongue and the posterior pharyngeal wall. In particular, after spraying mint water into the oral cavity, it will stimulate the salivary glands to secrete saliva, further aggravating the accumulation of secretions in the oral cavity and increasing the risk of aspiration and infection for the patient.

[0052] Based on this, in this embodiment, the isolation film 16 and the drainage trough 17 are provided on the nozzle 13. In the operation of sucking out the patient's oral secretions, the infusion tube 14 is used to push the nozzle 13 to slide downward along the tracheal tube until the end of the drainage trough 17 reaches the epiglottis of the human body; then the end of the isolation film 16 is connected to the suction pump. Under the action of negative pressure suction, the secretions accumulated between the root of the patient's tongue and the posterior pharyngeal wall enter the suction channel 18 through the drainage hole 20 and are discharged from the fitting gap of the isolation film 16, thereby avoiding the accumulation of secretions in the oral cavity and reducing the risk of aspiration and infection of the patient.

[0053] Furthermore, in this embodiment, after the end of the flow trough plate is delivered to the epiglottis of the human body, gas is injected into the blocking bag 21 through the liquid-filled flow channel 19 to make it expand. At this time, the blocking bag 21 can, on the one hand, block the airway in the epiglottis of the human body, prevent secretions from flowing into the trachea, and reduce the risk of aspiration; on the other hand, after the blocking bag 21 expands, it abuts against the outer wall of the endotracheal tube to generate a reaction force, driving the end of the drainage trough plate 17 to deflect toward the inner wall of the airway. Finally, the end of the drainage trough plate 17 can fit tightly with the mucosa of the posterior wall of the airway, so that the secretions collected in the posterior wall area of the airway can be sucked away, thereby improving the secretion removal effect, thereby further reducing the risk of aspiration and infection of the patient. At the same time, in this embodiment, after the blocking bag 21 is expanded, the end of the drainage groove plate 17 is separated from the endotracheal tube, and the drainage hole 20 provided on the inner wall of the drainage groove plate 17 can be more fully exposed, thereby improving the patency of secretions entering the suction channel 18; and the end of the drainage groove plate 17 is in contact with the outer wall of the endotracheal tube. At this time, an angle is formed between the drainage groove plate 17 and the posterior wall of the airway, thereby avoiding the risk of the drainage hole 20 provided on the outer wall of the drainage groove plate 17 adsorbing the mucosa of the posterior wall of the airway and causing mucosal damage.

[0054] Furthermore, when the blocking bag 21 is in an expanded state, it pulls the infusion tube 14 so that it drives the nozzle 13 and the drainage trough 17 to slide along the tracheal tube. During this process, the secretions adhering to the surface of the tracheal tube can fall off and fall into the groove of the drainage trough 17 for collection. Then, the secretions enter the suction channel 18 through the drainage hole 20 provided on the inner wall of the drainage trough 17 and are sucked away. In this way, the tracheal tube is kept clean and the risk of infection caused by secretions remaining in the airway after tracheal removal is reduced.

[0055] Furthermore, in this embodiment, the blocking sac 21 is expanded to apply a moderate squeezing force to the epiglottis tissue, which can promote the outflow of secretions hidden in anatomical gaps such as the vallecula and pyriform sinus, thereby further improving the secretion clearing effect.

[0056] In addition, in this embodiment, the isolation film 16 is sleeved outside the tracheal intubation tube, which can also reduce the friction between the tracheal intubation tube and the oral mucosa to a certain extent and reduce the risk of oral mucosa damage during the indwelling period of the tracheal intubation tube.

[0057] As a preferred implementation manner, on the basis of the above manner, further, the end of the drainage groove plate 17 is provided with a smooth rounded corner structure. This structural setting can reduce the risk of the drainage groove plate 17 pressing and injuring the mucosa of the posterior wall of the patient's airway, and improve the practical safety of the present invention.

[0058] Embodiment 3: As Figures 1 to 5 shown, for a deformable oral moistening component of the present invention, on the basis of the above manner, further, the upper bite plate 6 and the lower bite plate 9 are provided with tooth engaging grooves 22, and the tooth engaging grooves 22 are made of flexible silicone material, and the tooth engaging grooves 22 are used to accommodate the patient's teeth. With this structural setting, it can be avoided that the upper bite plate 6 and the lower bite plate 9 slide relative to the patient's teeth during actual use. On the one hand, it ensures the stability of the oral expansion state; on the other hand, it also reduces the risk of damage caused by the friction between the patient's teeth and the upper bite plate 6 and the lower bite plate 9.

[0059] As a preferred implementation manner, on the basis of the above manner, further, the surfaces of the upper bite plate 6 and the lower bite plate 9 are provided with slideways 23, the central axes of the slideways 23 are perpendicular to the surface of the cover plate 1, the tooth engaging grooves 22 are clamped in the slideways 23, and the tooth engaging grooves 22 can slide along the slideways 23. With this structural setting, it is convenient to adjust the positions of the tooth engaging grooves 22 on the upper bite plate 6 and the lower bite plate 9, so that the tooth engaging grooves 22 can more accurately correspond to the upper row of teeth and the lower row of teeth of the patient, thereby further improving the practicality of the present invention in actual use.

[0060] As a preferred implementation manner, on the basis of the above manner, further, a water-absorbing sponge 24 is provided on the surface of the cover plate 1 that contacts the human lips.

[0061] In this embodiment, the water-absorbing sponge 24 is provided to moisten the patient's lips, avoid the situation that the patient's lips crack during long-term use of the tracheal intubation tube, and improve the treatment comfort of the patient.

[0062] Embodiment 4: As Figure 1 and Figure 6As shown, the deformable oral moistening component described in the present invention is based on the above method. Further, the side of the cover plate 1 facing away from the human lips is further provided with a reinforcement component 25, and the reinforcement component 25 includes a base 26 and an abutment screw 27. The base 26 is arranged below the through hole 3, and the abutment screw 27 is threadedly connected to the through hole 3. The end of the abutment screw 27 is rotatably connected to a clamping head 28, and the clamping head 28 is used to connect a tracheal tube. The distance between the end of the abutment screw 27 and the cover plate 1 can be adjusted by twisting the abutment screw 27.

[0063] Specifically, the clamping head 28 in this embodiment is configured as a circular plate structure, and the diameter of the arc of the clamping head 28 matches the outer diameter of the endotracheal tube. In actual use, after the endotracheal tube passes through the through hole 3, the abutment screw 27 is turned counterclockwise to move its end upward until the clamping head 28 is tightly fitted to the endotracheal tube. The reinforcement member 25 in this embodiment provides better fixation of the endotracheal tube, reducing the risk of displacement or dislodgment of the tube during indwelling.

[0064] As a preferred embodiment, based on the above approach, the cover plate 1 is further provided with a channel groove 29. The width of the channel groove 29 matches the outer diameter of the endotracheal tube. One end of the channel groove 29 communicates with the through hole 3, and the other end extends through the side of the cover plate 1. The central axis of the channel groove 29 forms an acute angle with the vertical diameter line of the through hole 3, and the opening of the channel groove 29 is offset toward the top side of the cover plate 1. This structural arrangement improves the ease with which the endotracheal tube can be inserted into the through hole 3. Furthermore, the inclined arrangement of the channel groove 29 reduces the risk of the endotracheal tube accidentally falling out of the through hole 3.

[0065] Example 5: Figure 6 As shown, the mask described in the present invention includes a mask body 30 and the above-mentioned mouth wetting component, the mask body 30 is used to cover the human face, and the mouth wetting component is detachably connected to the mask body 30.

[0066] The mask body 30 provided in this embodiment can better cover the patient's mouth. On the one hand, it can reduce the risk of external pollution entering the oral cavity; on the other hand, it can reduce the evaporation rate of oral fluid and prolong the moisturizing time of the patient's mouth after the wetting operation.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
