Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional catheter for patients with swallowing disorders. Background Technology

[0002] Intermittent oro-esophagial tube feeding (IOE) is a nutritional support method for patients with dysphagia. The method involves inserting a tube through the mouth into the esophagus during feeding. Food is fed through the tube into the esophagus, where the patient's own gastrointestinal tract digests and absorbs the nutrients. The tube is removed after feeding. IOE is not only a nutritional support method but also an effective rehabilitation treatment for dysphagia.

[0003] Common operating procedure: The patient sits or is in a semi-recumbent position. The tip of the gastric tube is moistened with warm water and gently inserted into the middle of the esophagus through the mouth, with the insertion length about 25-30 cm from the incisors. The position of the gastric tube is checked to confirm that no air bubbles are escaping and that the patient does not experience choking or other discomfort. Then the gastric tube is fixed and liquid food is injected, 4-6 times a day, 400-500 ml each time.

[0004] Swallowing muscle balloon dilation is an effective treatment for dysphagia, especially for patients with cricopharyngeal achalasia, significantly improving swallowing function and quality of life. The procedure typically involves the patient sitting or semi-recumbent, with a suitable catheter (8-16 gauge double-lumen catheter) inserted orally into the esophagus. A certain amount of water or air is injected into the balloon to inflate it, thus dilating the cricopharyngeal muscle. The therapist mechanically pulls the catheter while guiding the patient to swallow. This achieves the therapeutic goals of inducing swallowing movements; training swallowing coordination; strengthening the swallowing muscle groups; stimulating sensation in the pharynx and cricopharyngeal muscle; and increasing the diameter of the cricopharyngeal muscle.

[0005] A search revealed Chinese patent CN 219517192 U, which discloses a multifunctional catheter for patients with swallowing disorders. This catheter delivers liquid food to the patient's stomach while simultaneously clearing food obstructing the esophagus and collecting sputum. The multifunctional catheter includes an esophagus with a sealed end and an open end. Several feeding holes communicating with the interior of the esophagus are located on the periphery near the sealed end. A bronchus is installed on the periphery near the open end. One end of a suction assembly is fitted over the esophagus, and the other end is located outside the patient's mouth. An infusion valve is fitted over the esophagus and located between the bronchus and the open end. A detachable cuff is installed at the end of the bronchus furthest from the esophagus and at the end of the suction assembly outside the patient's mouth. The cuff has an air chamber, and a removable canister is fitted over the cuff. A syringe is mounted on the canister and communicates with its interior.

[0006] The multifunctional catheter in the prior art can achieve both feeding and suctioning, but the catheter may be crushed or broken by the patient during feeding. Utility Model Content

[0007] In the aforementioned existing technology, during catheter feeding, patients may unconsciously bite down on or break the feeding catheter.

[0008] Technical approach: This application addresses the problems of existing technologies by providing a novel multifunctional catheter for patients with swallowing disorders. By detachably attaching an anti-biting tube component to the catheter body, it can effectively prevent patients from biting off the catheter. The balloon setting helps patients with oral swallowing training, and the acid-base test strip inside the catheter helps confirm whether the catheter has reached the stomach.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] This application provides a multifunctional catheter for patients with swallowing disorders, including a catheter body, an air bladder on the wall of the catheter body, an air bladder cavity and a feeding cavity that are not interconnected inside the catheter body, and an anti-biting tube assembly that is detachably connected to the catheter body.

[0011] Specifically, the tail end of the catheter body has a bifurcated structure.

[0012] Furthermore, the anti-bite tube assembly includes an anti-bite sleeve with a notch at its tail end. A locking plate is provided on one side of the anti-bite sleeve with a locking bolt on the other side, and the locking plate and the locking bolt cooperate with each other.

[0013] It should be noted that the anti-bite sleeve is truncated cone-shaped and has a through hole in the center, which is used to insert the catheter body.

[0014] Furthermore, the catheter body has multiple feeding holes penetrating the feeding cavity at its tip, and the catheter body is also provided with graduations.

[0015] Specifically, there are four feeding holes, which are arranged symmetrically in pairs.

[0016] In the above technical solution, a detachable guide wire is provided inside the feeding cavity, and an acid-base test paper is provided at the tip of the guide wire.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features a detachable anti-bite sleeve that can be attached to the outside of the catheter body. This effectively prevents patients from unconsciously biting down on or breaking the catheter body, thus preventing injury. The anti-bite sleeve can be moved freely on the catheter body, improving its practicality for patients and achieving a high degree of matching with each patient. Furthermore, the locking plate and locking bolt on the anti-bite sleeve can be used to lock the anti-bite sleeve in place after its position is adjusted, preventing the anti-bite sleeve from sliding and shifting, which would make it difficult for patients to bite down.

[0019] 2. This utility model has an independent air bladder cavity and a feeding cavity inside the catheter body, as well as an air bladder set on the wall of the catheter body. By inflating the air bladder with air or water through the air bladder cavity, the air bladder can expand. On the one hand, it can fix the catheter body and prevent the catheter body from slipping during feeding. On the other hand, it can guide the patient to swallow by mechanically pulling the catheter body. The expanded air bladder can expand the swallowing muscles and help the patient recover.

[0020] 3. This utility model, through the cooperation of the feeding cavity and the feeding hole, enables the injection of food into the lower part of the patient's esophagus and then into the stomach, thereby preserving the normal function of the gastrointestinal tract. In addition, by inserting a guidewire with acid-base test paper in the feeding cavity, the color development of the test paper can help medical staff quickly confirm whether the catheter body has reached the stomach, avoiding the catheter body from accidentally entering the trachea and causing harm to the patient.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] The inventors discovered that existing feeding tubes do not have a matching anti-bite device, which can easily lead to patients biting off the tube when it is inserted orally. The tube cannot be directly determined to be in the stomach, and medical staff need to rely on experience and a relatively complicated method to make a correct judgment. In addition, the tube does not have an air balloon, so it cannot be used for swallowing muscle balloon dilation training.

[0033] Based on the above findings, this application provides a multifunctional catheter for patients with swallowing disorders, including a catheter body 1, an air bladder 2 disposed on the wall of the catheter body 1, an air bladder cavity 3 and a feeding cavity 4 that are not interconnected inside the catheter body 1, and an anti-biting tube assembly 5 detachably connected to the catheter body 1. Example 1

[0034] Reference Figure 1-5As shown, this application provides a multifunctional catheter for patients with swallowing disorders, including a catheter body 1, an air bladder 2 disposed on the wall of the catheter body 1, an air bladder cavity 3 and a feeding cavity 4 that are not interconnected inside the catheter body 1, and an anti-biting tube assembly 5 detachably connected to the catheter body 1.

[0035] Preferably, the distance between the air bladder 2 and the tip of the catheter body 1 is 4-5 cm. Air or water is injected into the air bladder 2 through the air bladder cavity 3, causing the air bladder 2 to inflate. On the one hand, this serves to fix the catheter body 1 and prevent the catheter body 1 from sliding during feeding. On the other hand, the inflated air bladder 2 can be used to train the swallowing muscles, which is conducive to the patient's recovery.

[0036] Specifically, the catheter body 1 is 65cm long and comes in three models: F14, F16, and F18. F14 is suitable for children, while F16 and F18 are suitable for adults.

[0037] Furthermore, the anti-bite tube assembly 5 includes an anti-bite sleeve 51, the tail end of which has a notch 52. A locking piece 53 is provided on one side of the anti-bite sleeve 51 with a locking bolt 54 on the other side, and the locking piece 53 and the locking bolt 54 cooperate with each other.

[0038] In particular, the anti-bite sleeve 51 has a through hole with a diameter larger than the outer diameter of the conduit body 1, which facilitates the anti-bite sleeve 51 to slide and change position on the conduit body 1.

[0039] As an example, multiple locking holes are provided on the locking plate 53. By cooperating with the locking bolt 54 and the locking holes, the anti-bite sleeve 51 and the catheter body 1 can be locked and fixed, which makes it easier for the patient's teeth to bite the anti-bite sleeve 51 and avoids the problem of the patient biting off the catheter body 1.

[0040] Furthermore, the tip of the catheter body 1 is provided with multiple feeding holes 6 that penetrate the feeding cavity 4. The feeding holes 6 facilitate the injection of liquid food into the lower part of the patient's esophagus through the feeding cavity 4, and the liquid food flows into the patient's stomach through the lower part of the esophagus.

[0041] Preferably, there are four feeding holes 6, which are arranged symmetrically in pairs. Example 2

[0042] Based on Example 1, referring to Figure 6 As shown, in order to facilitate medical staff to determine whether the catheter body 1 has reached the patient's stomach, a scale is set on the catheter body 1, and a detachable guide wire 7 is provided in the feeding cavity 4.

[0043] Specifically, the end of the guide wire 7 is provided with acid-base test paper 8.

[0044] Specifically, the catheter body 1 is marked with graduations such as 25, 30, 35, 40, 45, 60, and 65 cm.

[0045] It should be noted that the guide wire 7 is 66cm long, which makes it easy for the guide wire 7 to be pulled out of the feeding cavity 4.

[0046] In actual use, the guidewire 7 with acid-base test paper 8 is inserted into the feeding cavity 4, and then the oral cannulation begins. After the cannulation is completed, the guidewire 7 is removed from the feeding cavity 4. The gastric juice is acidic, and the acid-base test paper 8 turns red when it comes into contact with acid, which can ensure that the catheter body 1 has been inserted into the patient's stomach.

[0047] Dysphagia refers to difficulty swallowing caused by various factors and occurring in different parts of the body. Dysphagia can affect food intake and nutrient absorption, and can also lead to aspiration pneumonia, which can be life-threatening in severe cases. It is important to identify the underlying disease causing the dysphagia and treat the cause accordingly. Rehabilitation training is a necessary measure to improve neurogenic dysphagia.

[0048] For patients with dysphagia, nutrition needs to be provided through feeding via a catheter, and cricopharyngeal muscle training is also necessary to facilitate early recovery. This application provides a multifunctional catheter for patients with dysphagia. In actual use, an anti-bite sleeve 51 is placed over the catheter body 1, and the anti-bite sleeve 51 can move along the catheter body 1 during insertion.

[0049] The guidewire 7, equipped with acid-base test paper 8, is then inserted into the catheter body 1 through the feeding cavity 4. The catheter body 1 is then inserted orally into the patient's stomach. After insertion, the guidewire 7 is removed from the feeding cavity 4. Since gastric juice is acidic, the acid-base test paper 8 turns red upon contact with the acid, confirming that the catheter body 1 has been inserted into the patient's stomach. The catheter body 1 is then withdrawn to 25-30 cm, positioning the feeding port 6 on the catheter body 1 in the lower middle segment of the esophagus.

[0050] The locking piece 53 on the anti-bite sleeve 51 is fastened to the locking bolt 54, so that the anti-bite sleeve 51 is fixed to the catheter body 1, and at this time the anti-bite sleeve 51 is in contact with the patient's teeth.

[0051] Furthermore, by filling the air bladder cavity 3 with gas or water, the air bladder 2 expands, thereby achieving the purpose of fixing the catheter body 1.

[0052] After the catheter body 1 is fixed, liquid food can be injected through the feeding cavity 4. The food in the feeding cavity 4 enters the middle and lower esophagus through the feeding port 6 and then flows into the patient's stomach, thereby providing nutrition to the patient.

[0053] During treatment, medical staff pull on the catheter body 1 and guide the patient to swallow. The inflated balloon 2 then expands the diameter of the cricopharyngeal muscle, which helps the patient recover.

[0054] In summary, although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
