Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a catheter device with pharyngeal cavity pressure measurement. BACKGROUND

[0002] Patients with swallowing disorders often have symptoms such as difficulty swallowing and unclear pronunciation. The pharyngeal cavity is the common pivot of swallowing and pronunciation, and it is affected by factors such as bolus tension and gravity, pharyngeal cavity pressure, and circopharyngeal muscle tension during the swallowing process. Insufficient pharyngeal cavity pressure can cause the swallowing process to proceed smoothly. In the clinical treatment process, the muscle groups of the pharyngeal cavity are usually trained to treat swallowing difficulties and unclear pronunciation. At this time, balloon dilation is usually used for treatment.

[0003] The existing balloon dilation generally uses a combination of a urinary catheter and a balloon. The catheter end is inserted into the balloon and fixed, inserted into the esophagus through the patient's nostrils, and the appropriate amount of water is injected into the balloon through the urinary catheter to increase the volume of the balloon. The mechanical expansion relieves the difficulty in swallowing caused by the slow loss of the circopharyngeal muscle, improves the coordination of the swallowing movement, and reconstructs the swallowing reflex nerve pathway.

[0004] However, the above-mentioned device has poor pressure sensing ability in actual use. In the prior art, the pressure of the water generated by the compression of the balloon is usually used to test the size of the swallowing pressure. When the installation position of the pressure sensor is too far from the balloon, the measurement data will be inaccurate. When it is installed inside the balloon, the external catheter will disperse the pressure when the balloon is pressed. In order to prevent backflow of the injected liquid, a clamping block is used at the tail end of the catheter to prevent backflow, which makes it difficult for the balloon to accurately obtain the pressure when less water is injected, reducing the measurement accuracy and use effect of the device. In view of this, we propose a catheter device with pharyngeal cavity pressure measurement. SUMMARY

[0028] In an embodiment of the present application, the sealing ring 75 is matched with the inner diameter of the air cavity 74, so that the sealing ring 75 can completely close the air cavity 74 to drive the sealing ring 75 to slide along the inner surface of the air cavity 74 when air is introduced or sucked into the air cavity 74, and the air cavity 74 is provided with a circular hole matched with the guide rod 76 near the end close to the balloon 6, and the guide rod 76 penetrates the circular hole, and in addition, the cross section of the stop block 77 is larger than the inner diameter of the inner sleeve 73, so that the stop block 77 can completely close the inner sleeve 73, and after enough water is injected, the inner sleeve 73 is closed by the stop block 77, so that the inner space of the balloon 6 is in a relatively independent state to better maintain its sealing performance and avoid affecting the swallowing rehabilitation training of the patient, and further, the pressure sensor 78 is electrically connected with the external display device, so that the pressure received by the pressure sensor 78 can be transmitted to the external display in real time to enable medical staff to timely know the pressure of the balloon 6 when subjected to swallowing action.

[0029] In addition, in order to reduce the influence of the continuous clamping and closing of the water injection pipe on the service life of the catheter 5, the inside of the control cabinet 1 is provided with an anti-backflow assembly 8, which comprises a shaped elastic block 81, the inside wall of the control cabinet 1 is fixedly installed with the shaped elastic block 81, the end of the communication pipe 4 is fixedly connected with the end of a silica gel hose 82, the top inside wall of the control cabinet 1 is fixedly installed with a fixed plate 83, the left side outer wall of the fixed plate 83 is fixedly connected with the right end of an extension rod 84, the left end of the extension rod 84 is fixedly connected with a transmission sliding block 85, the left side outer wall of the fixed plate 83 is fixedly connected with the right end of a return spring 86, and the left end of the return spring 86 is fixedly connected to the right side outer wall of the transmission sliding block 85.

[0030] In the embodiment of the present application, a circular hole is formed at the center of the shaped elastic block 81, and the silica gel hose 82 is arranged in the circular hole, so that when the spigot pipe 3 enters the silica gel hose 82 along the inside of the communication pipe 4, the silica gel hose 82 can be outwardly expanded, so that the spigot pipe 3-silica gel hose 82-communication pipe 4 and the inner sleeve pipe 73 keep a passage, so that the external syringe can inject and transport water into the balloon 6, at the same time, the silica gel hose 82 is under the inward pressure of the shaped elastic block 81 when it is not subjected to the force from inside to outside, and is in a closed state, thereby closing the passage between the communication pipe 4 and the spigot pipe 3, preventing the injected water from flowing back, and affecting the accuracy of the swallowing pressure test data, further, the return spring 86 is sleeved on the outside of the extension rod 84, so that the extension rod 84 can guide and limit the deformation direction of the return spring 86, specifically, the return spring 86 always keeps the horizontal direction of the deformation direction when it is subjected to extrusion or stretching, and will not be deflected in the vertical direction under the influence of its own gravity or extrusion, thereby the return spring 86 can always provide stable transmission effect for the transmission sliding block 85, in addition, the bottom end of the transmission sliding block 85 is fixedly connected to the arc-shaped outer wall of the injection pipe 2, and the top end of the transmission sliding block 85 is slidingly connected to the top inside wall of the control cabinet 1, so that when the external syringe is used to inject water, it is only needed to align the injection pipe 2 and push to the side of the control cabinet 1, thereby the spigot pipe 3 is pushed to the right along the inner wall of the communication pipe 4, until the silica gel hose 82 and the shaped elastic block 81 are opened, so as to ensure that the injected water can enter the inside of the balloon 6 through the inner sleeve pipe 73.

[0031] In addition, in order to avoid that the temperature of the injected water is too low to cause too much stimulation to the patient's cricopharyngeal muscle and pharyngeal cavity, causing the patient's discomfort, the inside of the spigot pipe 3 is provided with a preheating assembly 9, which comprises a mounting collar 91, the inner surface of the spigot pipe 3 is fixedly installed with the mounting collar 91, the inside of the mounting collar 91 is sleeved with a rotating rod 92, the rotating rod 92 penetrates a impeller 93, the impeller 93 is fixedly connected with the rotating rod 92, and the arc-shaped outer wall of the rotating rod 92 is fixedly installed with a heating pipe 94.

[0032] In the embodiment of the present application, the number of mounting collars 91 is provided with two groups, and the two groups of mounting collars 91 are respectively arranged at the left and right ends inside the plug-in pipe 3, and the inside of the mounting collar 91 is provided with a sleeve interface matched with the outer diameter of the rotating rod 92, so that the rotating rod 92 can rotate inside the mounting collar 91. Specifically, when the external syringe injects water into the plug-in pipe 3 through the injection pipe 2, the water flow drives the impeller 93 to rotate, and then drives the rotating rod 92 to rotate. In addition, the inside of the rotating rod 92 is provided with a battery to supply power to the heating pipe 94. In the process of continuous rotation of the rotating rod 92, the water passing through the plug-in pipe 3 is preheated by the movement of the heating pipe 94, so as to have a certain temperature to adapt to the temperature in the patient's oral cavity, avoid the stimulation of the water that is too cold to the patient's cricopharyngeal muscle and pharyngeal cavity, cause the patient to be injured, and thus affect the treatment effect of the patient.

[0033] In the present application, in use, the balloon 6 and the catheter 5 are stretched into the esophagus of the patient through the nasal cavity of the patient, and the balloon 6 completely passes through the cricopharyngeal muscle. At this time, the nurse uses the syringe to suck 10ml water and inject 6-9ml into the balloon 6, so that the balloon 6 expands. At this time, the syringe is pulled out, so that the silicone hose 82 is completely closed under the action of the plastic elastic block 81. At this time, the operator slowly pulls out the catheter 5 outward until the patient feels stuck or cannot be pulled out. A marker pen is used to mark the catheter 5 at the nostril as a reference point for the next expansion treatment. Then, air is introduced into the air pipe 71 to increase the air pressure in the air chamber 74, so that the sealing ring 75 moves to the right, and cooperates with the guide rod 76 to make the stop block 77 no longer shield the inner sleeve 73. At this time, the syringe is inserted into the injection pipe 2 to suck out an appropriate amount of water. According to the tension of the cricopharyngeal muscle, when the balloon 6 is pulled out, it can pass through but has a resistance, which is moderate. At this time, the balloon 6 is just at the cricopharyngeal muscle, and is continuously maintained for two minutes or the operator repeatedly pulls out the catheter 5 outward and alternately relaxes it. Once it has a sliding feeling or the pulling-out resistance sharply decreases, it indicates that the balloon 6 has slipped through the cricopharyngeal muscle. At this time, the air pump is started again to introduce air into the air chamber 74, and then the syringe is used to quickly suck out the water in the balloon 6. After that, the above operation is repeated to achieve the effect of exercising the cricopharyngeal muscle of the patient.

[0034] The above describes the present application in detail, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the protection scope of the present application.
