Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a three-lumen electrical stimulation balloon nasogastric tube for cricopharyngeal achalasia. Background Technology

[0002] Cricopharyngeal achalasia refers to a condition where the cricopharyngeal muscle is incompletely or completely closed. The etiology of this disease is not yet clear, but contributing factors include neurological disorders, tumors, and surgical injuries to the pharynx. Clinical manifestations include aspiration and dysphagia, which can lead to aspiration pneumonia, decreased immunity, and reduced nutrient intake, impacting the patient's health and quality of life. The conventional treatment for cricopharyngeal achalasia is swallowing rehabilitation training, but its clinical efficacy has not met expectations. In recent years, balloon dilation and pharyngeal electrical stimulation have become cutting-edge treatments for cricopharyngeal achalasia.

[0003] However, patients with cricopharyngeal achalasia require daily or every-other-day balloon dilation or pharyngeal electrical stimulation. During catheter insertion, patients experience significant discomfort, which can easily lead to rejection and refusal to cooperate with treatment. Furthermore, patients with cricopharyngeal achalasia often have nasogastric tubes in place, which already occupy a certain amount of nasopharyngeal space. Inserting a latex double-lumen balloon catheter further increases the difficulty of the procedure, increasing the risk of complications such as airway obstruction, nasopharyngeal bleeding, aspiration, and respiratory distress. Moreover, the placement of the electrodes in the pharyngeal electrical stimulation catheter requires precise positioning; successfully placing the electrodes in the middle of the pharynx has become a clinical challenge. Currently, the commonly used method is to perform laryngoscopy after pharyngeal electrical stimulation catheter insertion to determine the electrode position. This method is extremely cumbersome and further increases the number of catheter insertions and risks for the patient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a three-chamber electrical stimulation balloon nasogastric tube specifically for cricopharyngeal achalasia, which can simultaneously deliver food, expand the cricopharyngeal muscle balloon, and provide pharyngeal electrical stimulation therapy.

[0005] This utility model provides a three-chamber electrical stimulation balloon nasogastric tube specifically for cricopharyngeal achalasia, comprising a tube body, a nasogastric tube channel in the middle of the tube body, a balloon channel and a pharyngeal electrical stimulation channel respectively located inside the tube body and on both sides of the nasogastric tube channel, and a balloon, a first annular electrode and a second annular electrode arranged sequentially from bottom to top on the surface of the bottom of the tube body, the first annular electrode and the second annular electrode forming a bipolar annular electrode, and a filter plate located inside the nasogastric tube channel at the lower position, the surface of the filter plate having filter holes.

[0006] This invention, by adopting the above-described structure, combines the original single-lumen nasogastric tube, balloon tube, and pharyngeal electrical stimulation pathway into one, taking into account the functions of food delivery, balloon dilation of the cricopharyngeal muscle, and pharyngeal electrical stimulation therapy. It avoids the related problems caused by using a urinary catheter alone for balloon dilation or pharyngeal electrical stimulation, such as difficulty in insertion, bleeding, repeated insertion and removal, and patient intolerance. Furthermore, by setting the positions of the balloon and bipolar ring electrode, the location of the middle of the pharynx can be accurately positioned to achieve better therapeutic effects.

[0007] In one possible implementation, a metal guide wire is provided inside the nasogastric tube channel, a filter disc is fixedly provided at the bottom end of the metal guide wire, and a handle is fixedly provided at the top end of the metal guide wire.

[0008] In one possible implementation, the tube body is fixedly provided with a conduit at the bottom end, and the inner diameter of the conduit is smaller than the inner diameter of the nasogastric tube channel, and the surface of the tube body is provided with a liquid feeding port, and an arc-shaped inlet is provided at the bottom end of the conduit.

[0009] In one possible implementation, the top end of the tube is fixedly provided with a nasogastric tube injection port, and a sealing cap is provided above the nasogastric tube injection port to engage with the top end of the nasogastric tube injection port, and the sealing cap is connected to the side of the nasogastric tube injection port by a connecting strap.

[0010] In one possible implementation, a balloon injection port corresponding to the balloon channel is fixedly provided on the top of one side of the tube body, and a connecting tube is fixedly provided on the top of the balloon injection port.

[0011] In one possible implementation, a pharyngeal electrical stimulation catheter corresponding to the pharyngeal electrical stimulation channel is fixedly provided at the top of the other side of the tube, and a connector is provided at the end of the pharyngeal electrical stimulation catheter.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] See Figure 1-4As shown in the embodiment of this application, a three-lumen electrical stimulation balloon nasogastric tube for cricopharyngeal achalasia is disclosed, including a tube body 1. A nasogastric tube channel 101 is provided in the middle of the tube body 1. A balloon channel 102 and a pharyngeal electrical stimulation channel 103 are respectively provided inside the tube body 1 and on both sides of the nasogastric tube channel 101. A balloon 104, a first annular electrode 105, and a second annular electrode 106 are arranged sequentially from bottom to top on the bottom surface of the tube body 1. The first annular electrode 105 and the second annular electrode 106 form a bipolar annular electrode. The balloon is 35 cm away from the liquid feeding opening 201, and the annular electrode 105 is 35 cm away from the balloon 104. At the upper edge, 3cm away, the second ring electrode 106 is 1cm away from the upper edge of the first ring electrode 105. When the balloon 104 encounters resistance during water injection and lifting, it is considered that the upper edge of the balloon 104 is located at the lower edge of the cricopharyngeal muscle, i.e., the upper esophageal sphincter. The upper esophageal sphincter is about 3-5cm away from the middle of the pharynx. Therefore, at this time, the first ring electrode 105 and the second ring electrode 106 can accurately perform electrical stimulation treatment on the middle of the pharynx. Inside the nasogastric tube channel 101 and located at the lower position, there is a filter plate 401. The surface of the filter plate 401 is provided with filter holes 402 to filter the injected liquid food and prevent impurities from entering.

[0023] See you again Figure 3 As shown, the nasogastric tube channel 101 is provided with a metal guide wire 4 inside, which helps to insert the tube body 1. The filter plate 401 is fixedly installed at the bottom end of the metal guide wire 4, and the top end of the metal guide wire 4 is fixedly installed with a handle 403, which is convenient to operate the metal guide wire 4 and facilitates the removal of the filter plate 401 to clean the impurities filtered out.

[0024] See you again Figure 1 As shown, a catheter 2 is fixedly provided at the bottom end of the tube body 1, and the inner diameter of the catheter 2 is smaller than the inner diameter of the nasogastric tube channel 101, so that the filter plate 401 is installed at the bottom of the tube body 1, thereby limiting the position of the filter plate 401. The surface of the tube body 1 is provided with a liquid feeding port 201, and the distal end is a liquid feeding port 201. Multiple ports help the food to flow out, so that the liquid food injected into the nasogastric tube channel 101 can be discharged through the liquid feeding port 201. An arc-shaped inlet end is provided at the bottom end of the catheter 2, which is conducive to the insertion of the catheter 2 and will not cause damage.

[0025] See you again Figure 1 As shown, a nasogastric tube injection port 3 is fixedly provided at the top of the tube body 1. Liquid food is injected into the nasogastric tube channel 101 through the nasogastric tube injection port 3. A sealing cap 301 is provided above the nasogastric tube injection port 3 and engages with the top of the nasogastric tube injection port 3. The sealing cap 301 is sealed by engaging with the top of the nasogastric tube injection port 3. The sealing cap 301 is connected to the side of the nasogastric tube injection port 3 through a connecting strap 302 to prevent the sealing cap 301 from falling off or being lost.

[0026] See you again Figure 1 As shown, a balloon injection port 5 corresponding to the balloon channel 102 is fixedly provided on the top of one side of the tube body 1. A connecting tube 501 is fixedly provided on the top of the balloon injection port 5. The connecting tube 501 is connected to the injection port of the syringe. Water is injected into the inside of the balloon 104 through the balloon channel 102. The balloon injection port 5 and the nasogastric tube injection port 3 are side by side to form a balloon nasogastric tube.

[0027] See you again Figure 1 As shown, a pharyngeal electrical stimulation catheter 6 corresponding to the pharyngeal electrical stimulation channel 103 is fixedly provided at the top of the other side of the tube body 1. The end of the pharyngeal electrical stimulation catheter 6 is provided with a connector 601, which is used to connect to the pharyngeal electrical stimulation host. The first ring electrode 105 and the second ring electrode 106 are located in the middle of the pharynx, which is the most effective stimulation site for pharyngeal electrical stimulation. The pharyngeal electrical stimulation host is used in conjunction with the first ring electrode 105 and the second ring electrode 106 to perform electrical stimulation treatment on the middle of the pharynx.

[0028] When in use, first insert the tube 1 into the patient's mouth, inject the liquid food into the nasogastric tube injection port 3, and let the liquid food be discharged through the distal liquid food port 201, and use the internal filter plate 401 to filter impurities in the food.

[0029] When performing cricopharyngeal balloon dilation, it is not necessary to repeatedly insert the catheter every day. The syringe is connected to the connecting tube 501, water is injected into the balloon injection port 5, and water is then injected into the balloon 104. Then, the tube body is slowly pulled upwards 15-10cm until it is stuck, which confirms that it is at the lower edge of the cricopharyngeal muscle, that is, the upper opening of the esophageal sphincter. Then, the cricopharyngeal balloon dilation can be performed. After the procedure, the water in the balloon 104 is drained, and the tube body 1 is withdrawn 5-10cm, and the nasogastric tube can continue to be used.

[0030] During pharyngeal electrical stimulation therapy, water needs to be injected into balloon 104, and then the tube body 1 is pulled upwards and stopped when resistance is encountered. The upper edge of balloon 104 is located at the lower edge of the cricopharyngeal muscle, that is, the upper opening of the esophageal sphincter. The bipolar ring electrode located 3cm above the upper edge of balloon 104 is located in the middle of the pharynx, which is the most effective stimulation site for pharyngeal electrical stimulation. Thus, the pharyngeal electrical stimulation host, together with ring electrode one 105 and ring electrode two 106, performs electrical stimulation therapy on the middle of the pharynx, eliminating the need to confirm the position with a laryngoscope after tube insertion, reducing the number of tube insertions and the pain caused by repeated tube insertions for the patient.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
