Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a device for measuring and treating cricopharyngeal muscle expansion. Background Technology

[0002] Dysphagia is a disease caused by damage to the structure or function of the mandible, lips, tongue, soft palate, pharynx, esophagus, etc., which prevents food from being safely and effectively transported from the mouth to the stomach. Among them, cricopharyngeal achalasia is one of the causes of dysphagia. Craniopharyngeal achalasia is a disease caused by the inability of the cricopharyngeal muscle to fully relax. The causes include brain injury, stroke in the brainstem, malignant tumors of the head and neck, scar formation secondary to radiation and surgery, and post-intubation conditions.

[0003] Balloon dilation of the cricopharyngeal muscle is a treatment method used in the rehabilitation of dysphagia. It employs a standard catheter balloon (urinary catheter) and inflates it with water to create balloons of varying sizes, mechanically dilating the cricopharyngeal muscle to relieve dysphagia caused by cricopharyngeal muscle dysphagia. It is primarily used for cricopharyngeal muscle spasm caused by brain injuries such as stroke and radiation-induced encephalopathy, as well as dysphagia caused by scarring after head and neck cancer surgery. Balloon dilation can improve the coordination of swallowing movements and re-establish the neural pathways for the swallowing reflex. It also has good efficacy in treating swallowing incoordination, delayed swallowing reflex, and difficulty in initiating swallowing. In the field of dysphagia, balloon dilation is a highly technical rehabilitation treatment method. However, current balloon inflation methods are inconvenient for observing the amount of gas inflated and for measuring the pressure exerted on the balloon after inflation at the cricopharyngeal muscle insertion site, making them inconvenient for medical staff. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a cricopharyngeal muscle dilation measurement and treatment device, which effectively solves the problems of inconvenience in controlling the amount of gas inflated during cricopharyngeal muscle balloon dilation and inconvenience in detecting the pressure of the cricopharyngeal muscle on the balloon.

[0005] The technical solution is as follows: This utility model includes an air cylinder with its opening facing downwards and its vertical direction. Inside the air cylinder is a piston plate that can move up and down. A connecting block with vertical axial direction is fixed at the upper end of the air cylinder. A connecting groove is opened in the middle of the connecting block. Through holes are opened on the upper and lower sides of the connecting block, and the two through holes are connected to the connecting groove on opposite sides. The lower end of the lower through hole is connected to the inside of the air cylinder. An insert is detachably connected to the upper end of the upper through hole. An airbag is provided at the upper end of the insert. Arc-shaped elastic plates that can block the lower through hole are fixed on the left and right sides of the connecting groove. The two elastic plates protrude upwards on opposite sides and are in contact with each other. An arc-shaped connecting pipe is connected to the right end of the air cylinder. The upper end of the connecting pipe is connected to the upper through hole. A sealing device is provided in the middle of the connecting pipe.

[0006] This invention features a clever structure and is easy to use. It allows medical staff to control the amount of gas pushed into the intubation tube, and the gas inflates the inflatable bladder to expand the cricopharyngeal muscle for therapeutic treatment. During use, the gas does not flow back, ensuring the inflatable bladder remains inflated during movement and removal, thus improving the patient's treatment outcome. It also allows medical staff to monitor the pressure on the cricopharyngeal muscle after the bladder has inflated, and the gas inside the bladder can flow back to the inflation cylinder through the connecting tube, facilitating the reuse of the device. This invention is simple in structure, easy to operate, novel in design, and highly practical. Attached Figure Description

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 5 The invention includes an air cylinder 1 with its opening facing downwards and its vertical orientation. Inside the air cylinder 1 is a piston plate 2 that can move vertically. A connecting block 3 with vertical axial orientation is fixed to the upper end of the air cylinder 1. A connecting groove 4 is opened in the middle of the connecting block 3. Through holes 5 are opened on the upper and lower sides of the connecting block 3, and the two through holes 5 are respectively connected to the connecting groove 4 on opposite sides. The lower end of the lower through hole 5 is connected to the interior of the air cylinder 1. A tube 6 is detachably connected to the upper end of the upper through hole 5. An airbag 7 is provided at the upper end of the tube 6. Arc-shaped elastic pieces 8 that can cover the lower through hole 5 are fixed on the left and right sides of the connecting groove 4, and the two elastic pieces 8 protrude upwards on opposite sides and are in contact with each other. An arc-shaped connecting pipe 9 is connected to the right end of the air cylinder 1. The upper end of the connecting pipe 9 is connected to the upper through hole 5, and a sealing device is provided in the middle of the connecting pipe 9.

[0014] To facilitate control of the movement of the piston plate 2, a fixed plate 10 located below the piston plate 2 is fixed inside the air cylinder 1. A sliding rod 11 is slidably connected to the fixed plate 10. The upper end of the sliding rod 11 is fixedly connected to the piston plate 2, and the lower end of the sliding rod 11 extends out of the air cylinder 1.

[0015] To facilitate the sliding of the slide rod 11, the lower end of the air cylinder 1 is provided with an arc-shaped retainer 12, which contacts the slide rod 11. A push plate 13 is fixed on the slide rod 11, and a compression spring 14 is provided on the upper end of the push plate 13. The upper end of the compression spring 14 is connected to the fixing plate 10.

[0016] To facilitate the measurement of the pressure of the inflatable airbag 7 after inflation, a rectangular block 15 is fixed to the left end of the connecting block 3. A rectangular groove 16 is provided on the rectangular block 15. The right end of the rectangular groove 16 is connected to the connecting groove 4. The elastic sheet 8 on the left side can cover the right side of the rectangular groove 16. A gas pressure sensor 17 is fixed to the left end of the rectangular block 15.

[0017] In order to facilitate the left elastic sheet 8 to cover the rectangular groove 16, a stop block 18 is fixed in the connecting groove 4 above the rectangular groove 16. The stop block 18 is inverted L-shaped and can contact the left elastic sheet 8.

[0018] To facilitate the use of this device, the air cylinder 1 is made of transparent material, and the front side of the air cylinder 1 is provided with scale lines, with the lowest scale line being flush with the upper end surface of the piston plate 2.

[0019] To facilitate the assembly and disassembly of the insertion tube 6, a rotating block 19 is fixed on the insertion tube 6, and the rotating block 19 is threadedly connected to the upper end of the connecting block 3.

[0020] In order to control the connection of the connecting pipe 9, the sealing device includes a ball 20, which can block the inside of the connecting pipe 9. A circular groove 21 that runs vertically through the ball 20 is provided on the ball 20. A rotating column 22 that is rotatably connected to the connecting pipe 9 is fixed at the right end of the ball 20. A rotating handle 23 is provided on the rotating column 22.

[0021] When using this utility model, first rotate the 90-degree handle 23, so that the handle 23 drives the rotating column 22 and the ball 20 to rotate. The ball 20 drives the circular groove 21 and the connecting tube 9 to be disconnected. At this time, insert the intubation tube 6 into the patient's oral cavity and move it to the cricopharyngeal muscle. At this time, the medical staff squeeze the retaining sleeve 12 upward, the retaining sleeve 12 pushes the slide rod 11 to move upward and squeezes the compression spring 14. At the same time, the slide rod 11 drives the piston plate 2 to move upward. The gas in the air cylinder 1 located above the piston plate 2 flows into the connecting groove 4 through the through hole 5.

[0022] At the same time, the gas pushes the two elastic plates 8 to swing upward. The gas flows through the connecting groove 4 and into the intubation tube 6 through the upper through hole 5, and inflates the air bag 7. The inflated air bag 7 compresses the cricopharyngeal muscle of the patient. After the elastic plate 8 on the left swings, it blocks the rectangular groove 16. When the piston plate 2 moves a certain distance, the scale line determines that the piston plate 2 has pushed in an appropriate amount of gas. The movement of the stop sleeve 12 and the slide rod 11 stops. At this time, the two elastic plates 8 are reset and block the lower through hole 5. Since the two elastic plates 8 bulge upward on opposite sides, the gas in the air bag 7 will not flow back into the air cylinder 1.

[0023] At this time, the gas inside the inflatable balloon 7 comes into contact with the gas pressure sensor 17 through the intubation tube 6, the upper through hole 5, and the rectangular groove 16. The inflatable balloon 7 is inflated by the patient's cricopharyngeal muscle. Medical staff can use the gas pressure sensor 17 to determine the pressure received by the inflatable balloon 7 at the patient's cricopharyngeal muscle. Then, the medical staff manually pull the intubation tube 6 outward to keep the inflatable balloon 7 on the intubation tube 6 in an inflated state and move it out of the patient's cricopharyngeal muscle. During the movement of the inflatable balloon 7, it squeezes the cricopharyngeal muscle and treats the cricopharyngeal muscle.

[0024] After the intubation tube 6 is removed, rotate the handle 23 to connect the circular groove 21 on the ball 20 with the connecting tube 9. At this time, under the action of the compression spring 14, push the push plate 13 to move downward. The push plate 13 drives the slide rod 11 and the piston plate 2 to return to their original position downward. The gas in the intubation tube 6 and the inflatable air bag 7 is drawn into the air cylinder 1 through the connecting tube 9. Then, through the above process, the intubation tube 6 is inserted into the cricopharyngeal muscle of the patient again. Repeat the above operation to complete the cricopharyngeal muscle rehabilitation treatment of the patient.

[0025] This invention features a clever structure and convenient operation. By incorporating an inflation cylinder, piston plate, fixing plate, sliding rod, and stop, it allows medical personnel to easily control the amount of gas pushed into the intubation tube. The gas inflates the inflatable bladder, providing dilation therapy to the patient's cricopharyngeal muscle. Furthermore, the gas does not flow back during use, ensuring the inflatable bladder remains inflated during movement and removal, thus improving the patient's treatment outcome. Simultaneously, the gas pressure sensor, elastic plate, connecting tube, and sealing device allow medical personnel to monitor the pressure exerted on the cricopharyngeal muscle by the inflated bladder after inflation. The gas inside the bladder can also flow back to the inflation cylinder through the connecting tube, facilitating the reuse of this device. This design is simple, easy to operate, innovative, and highly practical.
