Description

Technical Field

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

[0002] Mechanical ventilation is a process in which mechanical devices replace or assist the work of respiratory muscles. It is a supportive therapy to maintain the patient's respiratory function and is widely used in the field of critical care. Patients who are intubated through the mouth cannot close their mouths and cannot eat or drink through the mouth because they are forced to change their normal breathing method. As the mechanical ventilation time increases, the water in the patient's oral mucosa evaporates, causing the patient to easily experience uncomfortable symptoms of dry mouth and thirst.

[0003] In clinical practice, a spray bottle is usually used to spray water mist into the patient's mouth to relieve the patient's thirst symptoms. However, in actual operation, the sprayed water mist often spreads to the back wall of the throat, irritating the throat area, which can easily cause the patient to cough violently, increasing the risk of endotracheal tube displacement or even dislocation.

[0004] Therefore, during the oral moistening operation for intubated patients, 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 prior art. Summary of the invention

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: 1. For a deformable oral moistening component according to the present invention, the upper supporting member and the lower supporting member are arranged on the inner side of the covering plate. In actual use, the upper airbag and the lower airbag are inflated to drive the upper bite plate and the lower bite plate to slide towards each other, which can expand the patient's oral cavity, so that the spray can be more evenly dispersed during the moistening operation, improving the effect of oral moistening. Further, an annular nozzle is sleeved on the tracheal intubation and extends to the root of the tongue. With the atomizing spray directed towards the covering plate, the water mist can accurately cover 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 dislodgment caused by coughing. Furthermore, the upper supporting member and the lower supporting member are arranged on the inner side of the covering plate 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 covering plate and the binding band can also be used to fix the tracheal intubation, improving the practicality of the present invention in actual application; 2. For a deformable oral moistening component according to the present invention, an isolation film and a drainage trough plate are arranged on the nozzle. During the operation of sucking out the patient's oral secretions, the infusion tube is used to push the nozzle to slide downward along the tracheal intubation until the end of the drainage trough plate reaches the epiglottis of the human body. Then, the end of the isolation film is connected to a suction pump. Under the action of negative pressure suction, the secretions accumulated between the patient's tongue root and the posterior pharyngeal wall enter the suction flow channel through the liquid guiding holes and are discharged from the matching gap of the isolation film, thus avoiding the accumulation of secretions in the oral cavity and reducing the risk of patient aspiration and infection; Further, after the end of the flow channel plate reaches the epiglottis part of the human body in this embodiment, gas is injected into the sealing bladder through the liquid filling flow channel to make it expand. At this time, on the one hand, the sealing bladder can block the airway at the epiglottis part of the human body, avoid the secretion 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 channel plate to deflect towards the inner wall of the airway. Finally, the end of the drainage channel plate can be closely attached to the mucosa of the airway posterior wall, so that the secretion gathered in the airway posterior wall area can be aspirated, improving the secretion clearance effect, 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 channel plate is separated from the tracheal intubation, and the liquid guiding holes provided on the inner wall of the drainage channel plate can be more fully exposed, improving the smoothness of the secretion entering the suction flow channel; and, the end of the drainage channel plate abuts against the outer wall of the tracheal intubation. At this time, an included angle is formed between the drainage channel plate and the airway posterior wall surface, avoiding the risk of the liquid guiding holes provided on the outer wall of the drainage channel plate adsorbing the airway posterior wall mucosa and causing mucosal damage.

[0017] Furthermore, when the sealing bladder is in an expanded state, pull the infusion tube so that it drives the nozzle and the drainage channel plate to slide along the tracheal intubation. During this process, the secretion adhering to the surface of the tracheal intubation can fall off and gather in the groove of the drainage channel plate. Subsequently, the secretion enters the suction flow channel through the liquid guiding holes provided on the inner wall of the drainage channel plate and is aspirated, thus keeping the tracheal intubation clean and reducing the risk of infection caused by the retention of secretion in the airway after tracheal extubation.

[0018] Even further, in this embodiment, by using the appropriate extrusion force exerted on the epiglottis tissue after the sealing bladder expands, the secretion hidden in the anatomical gaps such as the epiglottic vallecula and pyriform sinus can be promoted to flow out, thereby further improving the secretion clearance effect.

[0027] Embodiment 1: As Figure 1 and Figure 2As shown in the figure, a deformable oral moistening component according to the present invention includes a cover plate 1 and a strap 2. The cover plate 1 is used to cover the lips of a human body. A through hole 3 is provided on the 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 cover plate 1, and the strap 2 is used to fix the cover plate 1 on the head of a human body. On one side of the cover plate 1 in contact with the human lips, an upper supporting member 4 and a lower supporting member 5 are provided. The upper supporting member 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. The upper bite plate 6 is used to abut against the upper row of teeth of a human body. The lower supporting member 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. 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 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. 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 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. The nozzle 13 is sleeved on the endotracheal tube, and the water mist ejected from the nozzle 13 is directed towards the cover plate 1.

[0028] By using a deformable oral moistening component according to the present invention, the upper supporting member 4 and the lower supporting member 5 are arranged on the inner side of the cover plate 1. In actual use, the upper airbag 8 and the lower airbag 11 are used to drive the upper bite plate 6 and the lower bite plate 9 to slide towards each other when they expand, so that the oral cavity of a patient can be in an expanded state. Furthermore, during the moistening operation, the spray can be more evenly dispersed, improving the effect of moistening the oral cavity. Further, the annular nozzle 13 is sleeved on the endotracheal tube and extends to the root of the tongue, and is combined with the atomizing spray directed towards the cover plate 1, so that the water mist can accurately cover the oral mucosa without touching the posterior wall of the pharynx, avoiding irritation to the pharyngeal area and significantly reducing the risk of displacement and dislodgment of the endotracheal tube caused by coughing. Still further, the upper supporting member 4 and the lower supporting member 5 are arranged on the inner side of the cover plate 1 and directly abut against the teeth, avoiding the phenomenon of "biting the tube" during endotracheal intubation. On the one hand, it ensures the patency of the endotracheal tube, and on the other hand, it also reduces the risk of damage during the indwelling period of the endotracheal tube. Even further, in this embodiment, the cover plate 1 and the strap 2 are used in cooperation to also be able to fix the endotracheal tube, improving the practicality of the present invention in actual application.

[0029] 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 support member 4 and the lower support member 5 extend into the patient's oral cavity; bypass the strap 2 behind the patient's head, and adjust the tightness through Velcro or elastic buckles to ensure that the cover plate 1 is closely attached to the patient's lips; after completion, slowly inflate the upper airbag 8 and the lower airbag 11 through an external air pump, 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 are in close contact with the patient's teeth, then remove the oral opener, and at this time the patient's oral cavity can remain open.

[0030] During the operation of moistening the oral cavity, inject sterile mint water into the infusion tube 14 through the joint provided on the cover plate 1; during the spraying process, use an intermittent short-pulse mode, the single spraying time ≤ 3 seconds, and the total amount of single spraying ≤ 2 ml; after the moistening is completed, release the air in the upper airbag 8 and the lower airbag 11 to close the patient's oral cavity.

[0031] As a preferred embodiment, on the basis of the above method, further, a limiting channel 15 is provided 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.

[0032] In this embodiment, the connection between the infusion tube 14 and the cover plate 1 is set as a sliding connection fit. In the actual moistening operation, the infusion tube 14 is used to drive the nozzle 13 to slide along the tracheal intubation, which can change the position of the nozzle 13 in the patient's oral cavity, so as to achieve precise moistening of different positions in the oral cavity, improve the moistening effect and the practicality of the present invention.

[0033] Embodiment 2: As Figures 1 to 4 shown, for a deformable oral moistening 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 as a bilateral structure, the isolation film 16 extends from the through hole 3 to the outside, and the isolation film is used to cover the tracheal intubation; A drainage groove plate 17 is further connected to the spray head 13, and the drainage groove plate 17 extends in a direction away from the spray of the mist; the cross-section of the drainage groove plate 17 is set as an arc structure, and an attracting flow channel 18 and a liquid filling flow channel 19 are arranged inside the drainage groove plate 17. The liquid filling flow channel 19 is communicated with the infusion tube 14, and the attracting flow channel 18 is communicated with the isolation film 16; liquid guiding holes 20 communicated with the attracting flow channel 18 are further arranged on the inner wall and the outer wall of the drainage groove plate 17, and 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 as a double-chamber structure, and one chamber is used for conveying a wetting liquid to the spray head 13, and the other chamber is communicated with the liquid filling flow channel 19; A blocking capsule 21 communicated with the liquid filling flow channel 19 is further 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, and the blocking capsule 21 abuts against the tracheal intubation in an inflated state, so that the end of the drainage groove plate 17 can be attached to 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.

[0034] In this embodiment, it is considered that during the indwelling period of the tracheal intubation, 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, the liquid and mucus accumulate between the root of the tongue and the posterior pharyngeal wall. In particular, spraying mint water into the oral cavity 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 of the patient.

[0035] Based on this, in this embodiment, the isolation film 16 and the drainage groove plate 17 are arranged on the spray head 13. During the operation of sucking the oral secretions of the patient, the infusion tube 14 is used to push the spray head 13 to slide downward along the tracheal intubation until the end of the drainage groove plate 17 reaches the epiglottis part of the human body; then the end of the isolation film 16 is connected to a 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 attracting flow channel 18 through the liquid guiding holes 20 and are discharged from the matching gap of the isolation film 16, thus avoiding the accumulation of secretions in the oral cavity and reducing the risk of aspiration and infection of the patient.

[0036] Further, in this embodiment, after the end of the chute plate reaches the epiglottis of the human body, gas is injected into the blocking bladder 21 through the liquid filling channel 19 to make it expand. At this time, on the one hand, the blocking bladder 21 can block the airway of the human epiglottis part, avoid the secretion flowing into the trachea, and reduce the risk of aspiration; on the other hand, after the blocking bladder 21 expands, it abuts against the outer wall of the tracheal intubation to generate a reaction force, driving the end of the drainage chute plate 17 to deflect towards the inner wall of the airway. Finally, the end of the drainage chute plate 17 can be closely attached to the mucosa of the airway posterior wall, so that the secretion gathered in the airway posterior wall area can be aspirated, improving the clearance effect of the secretion, and further reducing the risk of aspiration and infection of the patient. At the same time, in this embodiment, after the blocking bladder 21 expands, the end of the drainage chute plate 17 is separated from the tracheal intubation, and the liquid guiding holes 20 provided on the inner wall of the drainage chute plate 17 can be more fully exposed, improving the smoothness of the secretion entering the suction channel 18; and, the end of the drainage chute plate 17 abuts against the outer wall of the tracheal intubation, and at this time, an included angle is formed between the drainage chute plate 17 and the airway posterior wall surface, avoiding the risk of the liquid guiding holes 20 provided on the outer wall of the drainage chute plate 17 adsorbing the mucosa of the airway posterior wall and causing mucosal damage.

[0037] Furthermore, when the blocking bladder 21 is in an expanded state, the infusion tube 14 is pulled to drive the nozzle 13 and the drainage chute plate 17 to slide along the tracheal intubation. During this process, the secretion adhered to the surface of the tracheal intubation can fall off and gather in the groove of the drainage chute plate 17, and then the secretion enters the suction channel 18 through the liquid guiding holes 20 provided on the inner wall of the drainage chute plate 17 and is aspirated, thus keeping the tracheal intubation clean and reducing the risk of infection caused by the retention of secretion in the airway after tracheal extubation.

[0038] Moreover, in this embodiment, by using the appropriate extrusion force exerted on the epiglottis tissue after the blocking bladder 21 expands, the secretion 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 secretion.

[0039] In addition, in this embodiment, by arranging the isolation film 16 to be sleeved outside the tracheal intubation, the friction between the tracheal intubation and the oral mucosa can be reduced to a certain extent, and the risk of damage to the oral mucosa during the indwelling period of the tracheal intubation can be reduced.

[0040] As a preferred implementation manner, on the basis of the above manner, further, the end of the drainage chute plate 17 is provided with a smooth rounded corner structure. Adopting this structural setting can reduce the risk of the drainage chute plate 17 pressing and injuring the mucosa of the airway posterior wall of the patient, and improve the practical safety of the present invention.

[0041] Example 3: As Figures 1 to 5As shown in the figure, for a deformable oral moistening component according to the present invention, on the basis of the above-described manner, further, the upper bite plate 6 and the lower bite plate 9 are provided with tooth engaging grooves 22, 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 arrangement, it is possible to avoid the upper bite plate 6 and the lower bite plate 9 from sliding relative to the patient's teeth during actual use. On the one hand, the stability of the oral expansion state is ensured; on the other hand, the risk of damage caused by friction between the patient's teeth and the upper bite plate 6 and the lower bite plate 9 is also reduced.

[0042] As a preferred embodiment, on the basis of the above-described manner, further, the surfaces of the upper bite plate 6 and the lower bite plate 9 are provided with sliding channels 23, the central axis of the sliding channels 23 is perpendicular to the surface of the covering plate 1, the tooth engaging grooves 22 are snap-connected in the sliding channels 23, and the tooth engaging grooves 22 can slide along the sliding channels 23. With this structural arrangement, 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 and lower rows of the patient's teeth, thereby further improving the practicality of the present invention during actual use.

[0043] As a preferred embodiment, on the basis of the above-described manner, further, a water-absorbing sponge 24 is provided on the side of the covering plate 1 that contacts the human lip.

[0044] In this embodiment, the provision of the water-absorbing sponge 24 can moisten the patient's lips, avoid the situation that the patient's lips crack during long-term use of the endotracheal tube, and improve the treatment comfort of the patient.

[0046] Specifically, the clamping head 28 in this embodiment is configured as a circular arc plate structure, and the diameter of the circular 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 screwed counterclockwise to move its end upward until the clamping head 28 is tightly fitted with the endotracheal tube.
