Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a saliva swallowing device. Background Art

[0002] After surgery on patients in the oral and bronchial departments, due to the weakness of the patients and the decreased swallowing function of the oral cavity, a large amount of saliva will accumulate in the patient's mouth. When there is too much saliva, it will overflow to the outside of the mouth corners, or during sleep, due to the decreased swallowing function of the oral cavity, saliva will remain on the outside.

[0003] The patient's saliva is retained on the outside of the mouth. Since saliva contains a large amount of acidic substances, it will cause great damage to the skin.

[0080] The use process of the saliva swallowing device provided by the present invention is as follows:

[0081] When the patient cannot control his teeth: cover the openings of the front mouth pocket 11, the side mouth pocket 12, and the corner mouth pocket 13 of the saliva mask 1 on the outside of the patient's lips, and then the front mouth pocket 11, the side mouth pocket 12, and the corner mouth pocket 13 will completely wrap the patient's lips on the inside of the saliva mask 1 through the remaining patch 14, and then use the elastic rope 15 to fix the saliva mask 1 on the patient's head to complete the wearing.

[0082] After the saliva mask 1 is put on, if the patient's saliva is left from the mouth, the saliva will flow to the surface of the liquid-absorbing cotton towel 53, and the liquid-absorbing cotton towel 53 will absorb the saliva into the inside to prevent the saliva from accumulating and covering the lips.

[0083] When the saliva hood 1 needs to be covered on the patient's mouth for a long time, the saliva hood suction tube 5 at the bottom of the saliva hood 1 can be connected to the three-way valve 6 or directly connected to the saliva suction device, and the saliva suction device is used to provide suction for the saliva hood suction tube 5, so that the saliva absorbed by the liquid absorption cotton towel 53 is absorbed by the leakage hole 52 on the top surface of the liquid absorption leakage box 51 and enters the inside of the saliva suction device, thereby avoiding the accumulation of saliva caused by the liquid absorption cotton towel 53, while maintaining the liquid absorption function of the liquid absorption cotton towel 53.

[0084] When the patient is able to control the teeth: an oral suction tube 2 is inserted into the front mouth pocket 11 of the saliva pocket 1, and at the same time, according to the distance between the patient's lips and teeth, the adjusting knob 25 is turned to engage with the adjusting thread 22 to adjust the position of the telescopic adjusting tube 21, so that the length of the telescopic adjusting tube 21 located at the saliva pocket 1 is the same as the distance between the patient's lips and teeth, and then the two sides of the posterior teeth silicone block 3 with the trigger plate 345 are placed to the patient's tooth position and fit on the outside of the patient's teeth, and then the saliva pocket 1 is attached to the patient's lips to complete the connection between the saliva pocket 1 and the oral suction tube 2.

[0085] It should be noted that the posterior teeth silicone block 3 can be used to replace the anterior teeth silicone block 4 according to the patient's needs. The anterior teeth silicone block 4 and the posterior teeth silicone block 3 have the same function and can both absorb the patient's saliva.

[0086] It should be noted that: when the posterior teeth silicone block 3 is connected to the oral pipette 2 and the anterior teeth silicone block 4 is connected to the oral pipette 2, they can be used separately when the patient can actively control the posterior teeth silicone block 3 or the anterior teeth silicone block 4. When the saliva cover 1 is used in combination with the oral pipette 2, the oral pipette 2 and the posterior teeth silicone block 3 can be placed in the patient's mouth first to complete the installation, and then the adjustment knob 25 of the saliva cover 1 is connected to the adjustment thread 22 of the oral pipette 2, so that the saliva cover 1 can fit the patient's lips.

[0087] After the posterior teeth silicone block 3 in the patient's mouth is connected and the saliva hood 1 is fixed, one end of the oral aspiration tube 2 is connected to the oral communication port 62 at the top of the three-way valve 6. When connecting, the sealing cover 64 needs to be removed first, and then the bottom end of the hood aspiration tube 5 is connected to the hood communication port 63 of the three-way valve 6 to complete the installation.

[0088] When in use, the suction regulating shaft 65 of the three-way valve 6 can be adjusted according to the patient's usage time, and the positioning knob 655 can be turned to drive the suction regulating plate 651 to rotate, so that the large hole 652, the middle hole 653, and the small hole 654 inside the suction regulating plate 651 can be connected to the hood connecting port 63 respectively. The size of the hole position can be changed according to the needs of use to adjust the suction size. During the adjustment process, the relative position of the large hole 652 and the hood connecting port 63 can be changed when turning to the large hole 652 to adjust the suction size.

[0089] When the positioning knob 655 is rotated, the second magnetic ring 664 will be driven to rotate synchronously. When the second magnetic ring 664 rotates, it is attracted to the first magnetic sheet 662 through the smooth sliding sheet 663, so the positioning knob 655 has a certain resistance. After the positioning knob 655 is rotated, the second magnetic ring 664 and the first magnetic ring can be adsorbed to fix the positioning knob 655 to maintain the connection position of the hood connecting port 63.

[0090] It should be noted that: since the oral aspiration tube 2 has a closing function through the setting of the posterior teeth silicone block 3, the oral aspiration tube 2 will not absorb saliva from the patient's mouth under normal conditions, and the saliva pocket 1 will always maintain suction after the adjustment is completed.

[0091] After the three-way valve 6 has adjusted the suction force of the saliva pocket 1, the patient can control the bite of the teeth on the posterior silicone block 3 by feeling the amount of saliva in the mouth, and control the connection between the suction tubes 33 at both ends of the posterior silicone block 3 and the oral suction tube 2 to achieve saliva adsorption.

[0092] It should be noted that when the posterior teeth silicone block 3 is in use, the patient is in a state of swallowing weakness, and the body will be affected by its own function to swallow saliva. During the swallowing process, the patient will unconsciously control the teeth to automatically bite. Therefore, the posterior teeth silicone block 3 can be used in a state where the patient has the function to control it, so as to achieve the absorption of saliva in the patient's mouth.

[0093] It should be noted that during the patient's occlusion, pressure will be applied to the trigger plates 345 arranged on the upper and lower sides of the posterior teeth silicone block 3. Then the trigger plates 345 press down to push the transmission bar 344 to move. The transmission bar 344 pushes the bottom hinged slider 341 to slide inside the trigger sliding chamber 34. When the slider 341 slides, it drives the telescopic slider 341 to move. The displacement of the telescopic slide plate 342 drives the suction hole blocking plate 343 to separate from the suction hole 32, opening the suction hole 32 to connect with the oral suction tube 2. After that, the suction force inside the oral suction tube 2 can absorb the saliva inside the patient's mouth through the suction tube 33.

[0094] After the saliva in the patient's mouth is completely absorbed and no force is applied, the posterior teeth silicone block 3 is subjected to the elastic force of the first spring 348 and the second spring 3491 to push the trigger plate 345 to its original position, and push the suction hole blocking plate 343 to reset, thereby blocking the suction hole 32. This reciprocating movement can achieve continuous absorption of the saliva in the patient's mouth.

[0095] It should be noted that when the interior of the saliva pocket cover 1 has suction, since the absorbent cotton towel 53 is attached to the surface of the leakage hole 52, the absorbent cotton towel 53 will cause a certain obstruction to the suction inside the pocket cover suction tube 5. At the same time, a ventilation hole is opened on the top outer wall of the saliva pocket cover 1, which can maintain the long-term use of the interior of the saliva pocket cover 1 for liquid absorption.
