Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a manometry balloon catheter for swallowing training. Background Art
[0002] The cricopharyngeal part is composed of the upper esophageal sphincter muscle (UESM), the cricopharyngeal muscle, the thyropharyngeal muscle, the circular muscle at the upper end of the esophagus, and the cartilaginous lower pharynx and cricoid cartilage. The sensation and movement of the upper esophageal sphincter and the cricopharyngeal muscle are innervated by the sensory fibers of the glossopharyngeal nerve and the voluntary motor fibers of the vagus nerve. Therefore, swallowing can be initiated voluntarily or reflexively caused by oropharyngeal stimulation. At rest, the upper esophageal sphincter is in a tense state. During swallowing, the food bolus is pushed into the pharynx by the strong contraction of the oral cavity, the tongue muscle, the pharyngeal muscle, etc. The upper esophageal sphincter relaxes, and after the food bolus enters the esophagus, it immediately contracts. This process takes about 0.3 s. After the swallowing movement, the esophageal body produces a peristaltic contraction and propels it into the stomach 0.5 - 1 s later, and then closes. Therefore, the swallowing movement is the result of the coordinated actions of the relaxation and contraction of the lower pharynx, the upper esophageal sphincter, the esophageal body, and the lower esophageal sphincter. If there is disharmony between swallowing and its relaxation during swallowing, it is difficult for the food bolus to enter the esophagus from the pharynx, resulting in dysphagia, that is, cricopharyngeal muscle relaxation inability, also known as esophageal orifice spasm. The dysfunction of the cricopharyngeal muscle group can be caused by nerve or muscle diseases.
[0003] Currently, the training of swallowing ability usually requires the repeated dilation of the cricopharyngeal muscle for many times. In the prior art, a balloon catheter is usually inserted into the patient's throat, and then the training is carried out through the patient's repeated swallowing movements and the repeated pulling of the balloon. However, this training method has a greater stimulation to the esophageal mucosa and pharynx, and is likely to cause secondary harm to the patient.
[0004] Therefore, in the prior art, there has been a continuous balloon implantation, and the training of the cricopharyngeal muscle is completed by repeatedly filling and contracting the balloon in a cycle.
[0005] However, in actual operation, since the overall length of the cricopharyngeal muscle is very short, only 1.6 - 1.9 cm, the implanted balloon is very easy to slip out of the cricopharyngeal muscle, and subsequently, the balloon needs to be pulled to reset it, so it may still cause greater stimulation to the esophageal mucosa. Content of the Utility Model
[0006] The purpose of the utility model is to provide a manometry balloon catheter for swallowing training to solve the technical problem in the prior art that a single balloon is easy to fall off and requires pulling and resetting.

Obviously, the drawings in the following description are only exemplary, and for those of ordinary skill in the art, other implementation drawings can be obtained by extending according to the provided drawings without creative efforts.

[0018] The reference numerals in the figure are respectively represented as follows:
[0019] 1. Main catheter; 2. Diversion catheter; 3. Core balloon; 4. Limiting balloon; 5. External inflation and deflation device. Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figure 1 shown, the present utility model provides a manometry balloon catheter for swallowing training, including a main catheter 1, the outside of which can be made of natural rubber, silicone rubber or polyvinyl chloride material or a soft medical-grade material for anti-adhesion. A diversion catheter 2 is arranged inside the main catheter 1, and the diversion catheter 2 is connected to an external inflation and deflation device 5. The external inflation and deflation device 5 can be set as a small device installed at the end of the main catheter 1, or can be a slightly larger device arranged on a platform and connected by the main catheter 1. At least three manometry balloons are sequentially sleeved outside the main catheter 1, and the three manometry balloons are continuously and independently installed on the outer wall of the main catheter 1. The diversion catheter 2 is connected to the manometry balloons to control the inflation and contraction of the manometry balloons through the external inflation and deflation device 5.
[0022] At least three manometry balloons include a core balloon 3 and a limiting balloon 4. The core balloon 3 is arranged in the middle, and the limiting balloons 4 are respectively arranged at both ends of the core balloon 3 to limit the core balloon 3 in the cricopharyngeal muscle. The core balloon 3 is inflated and deflated repeatedly for swallowing training.
[0023] Among them, a circulation hole can be opened on the main catheter 1 at the corresponding balloon position, and then a circulation hole is synchronously opened on the corresponding diversion catheter 2, so as to complete the one-to-one connection between the diversion catheter 2 and the corresponding balloon. The medium for controlling the inflation and contraction of the balloon can be gas or fluid. That is, the external inflation and deflation device 5 controls the inflation and contraction of the balloon by inflating and deflating or injecting and pumping water.
[0024] During specific use, after implanting the three manometry balloons into the patient's throat, the middle core balloon 3 is arranged at the cricopharyngeal muscle, and then the limiting balloon 4 is inflated to make the two of them expand and clamp at both ends of the cricopharyngeal muscle, so as to limit the core balloon 3 at the cricopharyngeal muscle.
[0025] Further, as an embodiment, there are at least three diversion tubes 2, and the three diversion tubes 2 are respectively connected to an external charging and discharging device 5, and the three diversion tubes 2 are respectively connected to each pressure measuring balloon in a one-to-one matching manner for separate charging and discharging control. The advantage of separately controlling each balloon is that it can be flexibly operated according to the actual usage situation. By separately controlling the core balloon 3, cricopharyngeal muscle training can be carried out through inflation and deflation operations. By separately controlling the upper limiting balloon 4, whose filling degree is greater than that of the core balloon 3, it can always keep the upper limiting balloon 4 above the cricopharyngeal muscle during the training process, so that the overall balloon will not drop out of the cricopharyngeal muscle due to swallowing movements.
[0026] By separately controlling the lower limiting balloon 4, it has the same effect. Making its filling degree greater than that of the core balloon 3 can always keep the lower limiting balloon 4 below the cricopharyngeal muscle during the training process, so that the overall balloon will not pop out of the cricopharyngeal muscle upward due to swallowing movements.
[0027] Most current swallowing balloons are spherical in shape. However, since the cricopharyngeal muscle is narrow and long, the contact area between the spherical balloon and the cricopharyngeal muscle is not comprehensive enough. Therefore, some muscles may not be trained properly. And if the diameter of the spherical balloon is large, it is easy to drop out of the cricopharyngeal muscle. If the diameter is small, the contact surface with the cricopharyngeal muscle will be further reduced. Therefore, the core balloon 3 of this device is set to be cylindrical. The cylindrical core balloon 3 is convenient to move in the pharynx, and its cylindrical surface can be fully contacted with the cricopharyngeal muscle, thereby improving the training effect.
[0028] In addition, hydrophilic lubricating coatings are provided on the outer surfaces of the core balloon 3 and the limiting balloon 4.
[0029] Further, a receiving and processing unit is provided inside the external charging and discharging device 5. The receiving and processing unit is signal-connected to the pressure measuring balloon, and the external charging and discharging device 5 continuously controls the filling degree of the pressure measuring balloon according to the pressure data provided by the pressure measuring balloon in real time. To detect the pressure value of the cricopharyngeal muscle during swallowing in real time, and dynamically adjust the expansion force, training duration and training frequency of the core balloon 3.
[0030] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
