Description

Technical Field

[0001] The present invention relates to the technical field of mouth openers, and more specifically, to an adjustable mouth opener for oral cancer surgery rehabilitation exercise. Background Art

[0002] Existing Chinese patent: A mouth opener for rehabilitation exercise after oral cancer radiotherapy (CN216497290U), through the setting of the airbag component, the airbag is inflated and exhausted to form a squeezing force on the upper and lower teeth, so that the mouth can be opened for exercise. Through repeated inflation and exhaust, the mouth opening exercise can be repeated, which effectively promotes local blood circulation, improves the effect of rehabilitation exercise, reduces the time used for patient rehabilitation, and accelerates the patient's recovery;

[0003] However, it does not have the function of cleaning saliva. During postoperative rehabilitation exercises for oral cancer, the mouth opener is first placed in the patient's mouth, and then the patient's mouth is stretched open by the mouth opener until the patient's temporal muscles feel slightly swollen, and then the patient's mouth is kept open for ten minutes. The patient's mouth will secrete a large amount of saliva after being stimulated by the mouth opener, and the patient's mouth needs to remain open, causing the saliva in the mouth to flow to the patient's neck and chest, increasing the difficulty of care. If a hose is used to absorb the saliva in the mouth, blockage will occur when the end of the hose contacts the oral assembly, and the saliva absorption effect is low. Summary of the invention

[0037] Five grooves 91 are formed on the upper side of the cover 206 ; the grooves 91 are used to guide the saliva on the upper side of the cover 206 to the inside thereof, so as to prevent the saliva on the upper side from dripping when the cover 206 is taken out.

[0038] The adjustment assembly includes a first shift block 209, a first fixed block 2010, a first round rod 2011, a second shift block 2012, a second fixed block 2013 and a spring 2014; each of the two first connecting blocks 2 is slidably connected with a first shift block 209, and the first shift block 209 is made of alloy; the two first shift blocks 209 are bolted to the corresponding second expansion block 202; two first fixed blocks 2010 are welded to the two first shift blocks 209, and the first fixed block 2010 slides on the inner side of the corresponding first connecting block 2; the first fixed block 2010 is provided with teeth; the two first Two first round rods 2011 are slidably connected to a connecting block 2; a second shifting block 2012 is welded to each of the first round rods 2011 on the same side; a second fixed block 2013 is welded to each of the first round rods 2011 on the same side, and the second fixed block 2013 is located on the inner side of the corresponding first connecting block 2; teeth are provided on the second fixed block 2013; each first fixed block 2010 is meshed with the corresponding second fixed block 2013; two springs 2014 are welded to each of the second fixed blocks 2013, and the springs 2014 are welded to the corresponding first connecting block 2.

[0039] The adjustment component also includes a lever 2015; the lever 2015 is bolted between the two first shifting blocks 209, and the two first shifting blocks 209 can be controlled simultaneously by manually shifting the lever 2015, making the operation more convenient.

[0040] It also includes a guide component; the guide component is connected to the cover shell 206; the guide component includes a guide plate 2016 and a second pipe 2017; a guide plate 2016 is welded on the lower left and lower right sides of the cover shell 206, and the guide plate 2016 is used to limit the airflow flowing into the cover shell 206, thereby avoiding the problem of airflow flowing from the oral surface to stimulate the oral tissue and increase the saliva secretion; three second pipes 2017 are penetrated on the lower left and lower right sides of the cover shell 206, and the second pipes 2017 are located below the corresponding guide plates 2016.

[0041] First, the medical staff opens the patient's mouth, and then puts the first expansion block 201 bending part and the cover shell 206 into the patient's mouth, so that the patient's upper teeth are stuck in the upper first expansion block 201 bending part, and the patient's lower teeth are stuck in the lower first expansion block 201 bending part, so that the cover shell 206 is pressed against the lower side of the patient's tongue. At this time, the lower side of the cover shell 206 contacts the bottom of the mouth, and then the medical staff moves the thumb and index finger of the left hand to the inside of the two second shift blocks 2012, and then pushes the two second shift blocks 2012 to move back to back, the second shift block 2012 drives the first round rod 2011 to move, the first round rod 2011 drives the second fixed block 2013 to move, the second fixed block 2013 compresses the spring 2014, so that the second fixed block 2013 stops contacting the first fixed block 2010, and then The right hand manually pushes the lever 2015 to move downward, and the lever 2015 drives the two first blocks 209 to move downward, and the first block 209 drives the first fixed block 2010 and the second expansion block 202 to move downward, so that the second expansion block 202 below moves downward, and the second expansion block 202 below pushes the patient's lower teeth to move downward, thereby pushing the patient's lower jaw to open downward, until the patient's temporal muscles feel swollen. The medical staff stops pushing the two second blocks 2012, and the spring 2014 rebounds and drives the second fixed block 2013 to move back to its original position, so that the second fixed block 2013 re-fixes the first fixed block 2010, and fixes the second expansion block 202 below, thereby realizing adaptive adjustment of the patient's mouth opening size, and the patient's mouth remains open for ten minutes to complete the mouth opening exercise.

[0042] During the mouth opening exercise, the saliva secreted by the patient flows to the bottom of the mouth, and the lower side of the cover 206 contacts the bottom of the patient's mouth, so that the saliva flows to the inside of the cover 206 and contacts the first pipe 207. The water pump 203 is started to make the saliva flow through the first pipe 207, the first telescopic hose 204 and the water pump 203 to the collection box 208 for collection, completing the saliva suction operation and avoiding the problem of saliva flowing into the patient's neck and chest and causing nursing difficulties. At the same time, the first pipe 207 is isolated from the oral tissue by the cover 206, avoiding the problem of oral tissue blocking the port of the first pipe 207 and causing low saliva suction efficiency. The oral tissue can also be protected with high safety.

[0043] When the amount of saliva is small, the first pipe 207 will inhale some air. At this time, air flow from outside to inside is formed at the bottom of the cover shell 206, that is, the air flows from the bottom of the mouth to the inside of the cover shell 206. The flowing air in this process will stimulate the tissue at the bottom of the mouth, thereby causing the mouth to secrete more saliva. At this time, the air is guided and limited by the guide plate 2016, so that the air flows obliquely downward to the inside of the cover shell 206, effectively preventing the air from flowing from the bottom of the mouth to the inside of the cover shell 206 to stimulate the oral tissue, thereby greatly reducing the patient's saliva secretion. At this time, the saliva in the mouth flows from the second pipe 2017 to the cover shell 206, and is sucked away by the first pipe 207.

[0044] Implementation 2

[0045] Based on Implementation Plan 1, Figure 1-2 and Figure 8-10 As shown, it also includes a covering assembly; the covering assembly is connected to the cover shell 206; the covering assembly includes a third shift block 2020, a second round rod 2021, a stop block 2022 and a fixing unit; two second round rods 2021 are connected to the cover shell 206 in a damping sliding manner; the two second round rods 2021 are rotatably connected to a third shift block 2020, and the third shift block 2020 is set to an alloy material; the two second round rods 2021 are slidingly connected to the corresponding guide plate 2016; a stop block 2022 is welded to the lower end of the two second round rods 2021, and the second pipe 2017 is blocked by the stop block 2022 to prevent saliva on the inside of the cover shell 206 from flowing out of the second pipe 2017 when the cover shell 206 and the parts thereon are taken out; the cover shell 206 is connected to a fixing unit.

[0046] The fixing unit includes a third fixing block 2018 and a first protrusion 2019; two third fixing blocks 2018 are welded on the cover shell 206; two first protrusions 2019 are welded on the two third fixing blocks 2018, and the first protrusions 2019 are set to an alloy material; the two third shift blocks 2020 are in contact with the corresponding third fixing blocks 2018; the two third shift blocks 2020 are in contact with the corresponding first protrusions 2019.

[0047] During the exercise, some saliva will flow along the tongue on the upper side of the cover 206. After the exercise, when the cover 206 is taken out, the saliva on the upper side of the cover 206 will drip onto the patient's clothes or bed. Therefore, a groove 91 is opened on the cover 206 to allow the saliva on the upper side of the cover 206 to flow from the groove 91 to the inside of the cover 206, and then be sucked away through the first pipe 207, effectively preventing the saliva on the upper side of the cover 206 from dripping onto the patient's clothes or bed when the cover 206 is taken out, thereby reducing pollution.

[0048] After the exercise is completed, before taking out the cover shell 206, the medical staff pushes the third block 2020 to move upward, and the third block 2020 drives the second round rod 2021 to move upward, so that the third block 2020 is away from the third fixed block 2018 and the first protrusion 2019, and then drives the third block 2020 to rotate ninety degrees, and then pushes the third block 2020 to move downward, the third block 2020 drives the second round rod 2021 to move downward, and the second round rod 2021 drives the stopper 2022 to move downward, so that the stopper 2022 blocks the port of the second pipe 2017, so as to avoid the cover shell 206 and its parts being tilted when being taken out, causing the residual saliva to flow out of the second pipe 2017 to the patient's clothes or bed, thereby further reducing contamination.

[0049] Implementation 3

[0050] Based on Implementation Plan 2, Figure 1-2 and Figure 11-13 As shown, it also includes a locking assembly; the outer shell 1 is connected to the locking assembly; the locking assembly includes a third connecting block 301, a fourth connecting block 302, a universal ball 303, a first cylinder 304, a second cylinder 305, a third cylinder 306, a second protrusion 307 and an inflatable unit; the cover 206 is bolted with a third connecting block 301; a fourth connecting block 302 is welded to the third connecting block 301 and the outer shell 1; the two fourth connecting blocks 302 are rotatably connected to A universal ball 303; a first cylinder 304 is welded to the universal ball 303 located at the bottom; a second cylinder 305 is slidably connected to the first cylinder 304; a third cylinder 306 is bolted to the outside of the second cylinder 305; the third cylinder 306 is welded to the universal ball 303 located at the top; two second protrusions 307 are welded to the inside of the second cylinder 305; the two second protrusions 307 are both slidably connected to the first cylinder 304; an inflation unit is connected to the first cylinder 304.

[0051] The inflation unit includes a first rubber block 308, a second telescopic hose 309, a second rubber block 3010, a third telescopic hose 3011 and an air pump 3012; a first rubber block 308 is fixedly connected to each of the two fourth connecting blocks 302, and the first rubber block 308 is fixed to the universal ball 303 after expansion; a second telescopic hose 309 is connected to each of the two fourth connecting blocks 302, and the second telescopic hose 309 can be a round tube or a square tube; two second rubber blocks are fixedly connected to the second cylinder 305 3010, the second rubber block 3010 is expanded to fix the first cylinder 304 and the second cylinder 305; the third cylinder 306 is connected with a third telescopic hose 3011; an air pump 3012 is fixed to the inner side of the shell 1; the third telescopic hose 3011 and the two second telescopic hoses 309 pass through the shell 1 and are connected with the output end of the air pump 3012; a first cavity 92 is formed between the fourth connecting block 302 and the first rubber block 308; a second cavity 93 is formed between the second cylinder 305 and the third cylinder 306.

[0052] The inflation unit further includes a cylinder 3013 ; the cylinder 3013 is welded on the inner side of the third cylinder 306 ; and the first cylinder 304 slides on the surface of the cylinder 3013 .

[0053] For some patients with weak muscle control, the tongue will unconsciously move the cover 206, so that the cover 206 rubs against the patient's mouth, stimulates the oral tissue, and then increases the amount of saliva secretion. When the cover 206 is placed under the tongue, the cover 206 drives the third connecting block 301 to move, the third connecting block 301 drives the fourth connecting block 302 to move, and the fourth connecting block 302 drives the universal ball 303 to move and rotate, so that the universal ball 303 drives the first cylinder 304 to move and swing, so that the first cylinder 304 slides in the second cylinder 305, and at the same time, the first cylinder 304 drives the second cylinder 305 to swing, the second cylinder 305 drives the third cylinder 306 to swing, and the third cylinder 306 drives the universal ball 303 thereon to rotate. Thereby, the cover shell 206 can move freely to under the tongue. After the cover shell 206 is pressed under the tongue, the air pump 3012 supplies air to the second telescopic hose 309, and the second telescopic hose 309 supplies air to the first cavity 92, so that the second rubber block 3010 expands and presses the universal ball 303 to fix it. At the same time, the air pump 3012 supplies air to the third telescopic hose 3011, and the third telescopic hose 3011 supplies air to the second cavity 93, so that the first rubber block 308 expands and fixes the first cylinder 304 and the second cylinder 305 together, thereby fixing the cover shell 206 after the position adjustment is completed, effectively avoiding the friction between the cover shell 206 and the patient's mouth to stimulate the oral tissue, thereby reducing the amount of saliva secretion and improving the saliva cleaning efficiency.

[0054] When the first cylinder 304 slides downward inside the second cylinder 305, a relatively large space is formed between the upper side of the first cylinder 304 and the second cylinder 305. When the second rubber block 3010 expands, the position of the second rubber block 3010 corresponding to the space loses the limiting effect of the first cylinder 304, so that the expansion degree of the second rubber block 3010 corresponding to the space is much greater than that of the lower part, which makes the second rubber easily damaged. At this time, a cylinder 3013 is set in the middle of the third cylinder 306. When the first cylinder 304 slides downward inside the second cylinder 305, the upper part of the second rubber block 3010 is limited by the cylinder 3013 instead of the first cylinder 304, so as to avoid the upper part of the second rubber block 3010 from being damaged due to excessive expansion.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
