Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a diaphragmatic electrical signal acquisition catheter system. Background Art

[0002] The diaphragmatic electrical signal monitoring technology is a monitoring technology that monitors the potential changes generated when the diaphragm is excited by placing an esophageal electrode catheter for diaphragmatic electrical activity, understands the driving ability of the respiratory center, and evaluates the function of the respiratory muscles. A series of signal processing is required to design a ventilator trigger using diaphragmatic electrical signals. Among them, electrode wires are designed on the gastric tube to monitor the diaphragmatic electrical signals at the esophagus, and the position of the catheter also needs to be reasonably positioned to ensure the nasogastric function of the gastric tube and provide assistance for subsequent signal processing. When a patient undergoes magnetic resonance imaging (MRI) examination, no metal foreign objects can be carried on the body, as such items may affect the MRI examination and are not conducive to the display of lesions.

[0003] In Chinese Utility Model Patent Application No.: 202223084768.0, a monitoring type jejunal feeding tube is disclosed, which includes a feeding tube. A feeding cavity is fixed at the upper end of the feeding tube, and a pressure regulating cavity is also fixedly connected at the connection of the feeding tube and the feeding cavity. An aspiration cavity is also fixedly connected at the position where the feeding tube is provided with the pressure regulating cavity. A reference electrode is provided on the lower surface of the feeding tube where the feeding cavity is provided, and a detection electrode is also provided at the lower end of the surface of the feeding tube where the reference electrode is provided. This monitoring type jejunal feeding tube is not convenient for clamping and positioning the inner tube body of the jejunal tube during actual use, and the tube bodies cannot be freely switched. When the patient uses it for a long time, there is no sealing mechanism at the contact part between the gastric tube and the outside, resulting in germs entering the patient's body, and it is not convenient for collecting diaphragmatic electrical signals and cannot perform MRI examinations.

[0004] Therefore, it is very necessary to propose a diaphragmatic electrical signal acquisition catheter system to solve the above problems. Summary of the Invention

[0044] Embodiment 3

[0045] Please refer to Figures 1-9 , in this embodiment, the following optimizations are made on the basis of Example 1 or Example 2. Specifically, an anti-inhalation airbag 29 and an anti-gastric reflux airbag 30 are successively arranged at the bottom end of the jejunum tube body 1. Air delivery connection pipes 31 are fixedly connected inside both the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30. The bottom of the air delivery connection pipe 31 penetrates through the jejunum tube body 1 and is connected to the inflation pipe 27. First, inject air from the pressure measurement port to ensure that the airbag is intact. The device at the in-body end of the jejunum tube is composed of an inflatable anti-inhalation airbag 27 and an air delivery connection pipe 31 connected thereto. The auxiliary cavity joint 10 at the outer end of its pipeline is connected through a three-way extension pipe. The extension pipe is connected to the ventilator interface. Connect the three-way of the extension pipe to the pressure measurement pipe. Inject 8 ml of gas into the airbag, draw back 3 ml and retain 5 ml of gas. Press the patient's abdomen. A positive wave appears in the esophageal pressure waveform on the ventilator interface, while there is no corresponding change in the airway pressure, indicating that it is in the stomach. Withdraw the gastric tube. A heartbeat notch appears during the withdrawal process, indicating that it is close to the ideal position. If the patient has no spontaneous breathing, press the respiratory hold key and press the chest at the same time. Measure the change value of the airway pressure and the change value of the esophageal pressure. If the ratio is between 0.8 and 1.2, it indicates that the position is correct, and monitor the esophageal pressure.

[0046] Specifically, one end of the air delivery connection pipe 31 is fixedly connected with an annular connection pipe 32. Sector balloons 33 are symmetrically and fixedly connected to the outer side of the annular connection pipe 32. One end of the annular connection pipe 32 successively penetrates through the sector balloons 33 and is communicated with the inside of the sector balloons 33. Air leakage holes 34 are symmetrically opened on the outer side of the sector balloons 33. Both sides of the sector balloons 33 are fixedly connected to the inner wall of the anti-inhalation airbag 29. There are multiple sector balloons 33, and the multiple sector balloons 33 are distributed in a rectangular array.

[0047] Specifically, an Edi catheter 35 is arranged on one side of the Edi test plug 16 inside the fixing block 2. A linkage spring 36 is fixedly connected to the outer side of the Edi catheter 35. One end of the linkage spring 36 is fixedly connected with a connection closing plate 37. The end of the Edi catheter 35 inserted into the body is fused with the outer surface of the jejunum tube body 1. Edi is detected by 10 electrodes (one for positioning and the others for collecting the diaphragmatic electrical signals of the patient). The contraction activity of the diaphragmatic muscle generates a force on the electrodes on the catheter. The electrodes on the catheter use this force to convert electrical signals to supply the ventilator system. The tube body also contains a barium wire for X-ray examination. The electrode materials of the EDI device mainly include a titanium anode, a titanium cathode, and an ion exchange membrane, which do not affect magnetic resonance examination during the use of the patient in the body.

[0048] Specifically, an internal thread groove 38 is opened at the top of the fixing block 2 inside the connection closing plate 37. An Edi test plug 16 is threadedly connected inside the internal thread groove 38. An external thread adapted to the internal thread groove 38 is opened at the bottom end of the Edi test plug 16.

[0049] In this embodiment, an air delivery connection pipe 31 is arranged inside the inflation pipe 27 and connected to the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30 to inflate the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30. With the cooperation of the annular connection pipe 32, the sector balloon 33 and the air vent hole 34, the airbag can be pre-inflated and the patient's tolerance can be tested. After the test, the airbag can be fully inflated and clamped at a specific position for use. The end of the Edi test plug 16 is connected to the internal thread groove 38, pushing the linkage spring 36 to contract, so that the top of the connection closing plate 37 is connected to the Edi test plug 16 and the bottom is connected to the Edi catheter 35, thereby completing the connection between the Edi catheter 35 and the Edi test plug 16, and making the inside of the Edi catheter 35 communicate with the outside world, and closing the pipe orifice when not in use.

[0050] Working principle: Lubricate the outer surface of the jejunum tube body 1 with paraffin oil and lubricate the guide wire to facilitate the insertion and extraction of the jejunum tube body 1 into the patient's stomach. Hang the device by pulling out the L-shaped rod 5 from the reset groove 3, and the pulled L-shaped rod 5 can be contracted through the reset spring 4. By pressing the clamping plate 7 inward to contract the support spring 8, the clamping ring 11 on the inner side of the other end of the clamping plate 7 is connected to the clamping groove 12 at the end of the nutritional feeding joint 9 to fix one end of the nutritional feeding joint 9. When the nutritional feeding joint 9 is taken out, the closing spring 14 in the storage groove 13 pushes the two T-shaped closing plates 15 to move inward to close the internal pipeline. The U-shaped rod 20 on the outside of the auxiliary cavity joint 10 moves in the translation groove 17 on the inner wall and is limited by the limit post 18 and the limit groove 19, so that the built-in spring 21 pushes the U-shaped rod 20 to move only in a specific direction, and the outer end of the U-shaped rod 20 is clamped with the linkage groove 22 and drives the rotating plate 23 to rotate, so that the tooth groove 25 on the outer surface of the rotating plate 23 is connected to the linkage gear 28, and the rotation angle of the linkage gear 28 is the same as the rotation angle of the rotating plate 23, so that the infusion pipeline 26 and the inflation pipeline 27 can be observed externally when switching. An air delivery connection pipe 31 is arranged inside the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30 and connected to the inflation pipe 27. When the jejunum tube body 1 is placed at a specified position in the patient's body, the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30 are inflated. Under the connection of the annular connection pipe 32, the sector balloon 33 is inflated and positioned first. When the patient has no abnormal reaction, the airbag is fully inflated through the air vent hole 34 and clamped at a specific position for use. The end of the Edi test plug 16 is connected to the internal thread groove 38, pushing the linkage spring 36 to contract, so that the top of the connection closing plate 37 is connected to the Edi test plug 16 and the bottom is connected to the Edi catheter 35, thereby completing the connection between the Edi catheter 35 and the Edi test plug 16, and making the inside of the Edi catheter 35 communicate with the outside world, and is connected to the module cabin of the ventilator system through the Edi cable and the Edi module.

[0051] In summary: For the present invention, by installing the fixed block 2 at the top of the jejunum tube body 1, the reset spring 4 is made to push the L-shaped rod 5 to move within the reset groove 3, so that when the device is not in use, it can be hung at a designated position. The middle end of the clamping plate 7 is limited by the adjustment groove 6, and under the action of the support spring 8, the clamping ring 11 on the inner side of the other end of the clamping plate 7 is connected to the clamping groove 12 at the end of the nutritional feeding joint 9, ensuring that the nutritional feeding joint 9 and the fixed block 2 will not separate during use. By the closing spring 14 in the storage groove 13 pushing the two T-shaped closing plates 15 to move inwards, the internal pipeline is closed when the nutritional feeding joint 9 is taken out. By using polyurethane for the material of the part of the tube body of the jejunum tube body 1 in contact with the human body, titanium alloy for the spring material, and plastic for the threads, the patient can also undergo magnetic resonance examination during wearing, avoiding frequent tube extraction by the patient. By accommodating the U-shaped rod 20 in the translation groove 17 on the inner wall of the auxiliary cavity joint 10 and limiting it through the limit post 18 and the limit groove 19, the built-in spring 21 is made to push the U-shaped rod 20 to move only in a specific direction, so that the outer end of the U-shaped rod 20 is connected to the linkage groove 22 and drives the rotating plate 23 to rotate. The through holes 24 are respectively connected to the infusion pipeline 26 and the inflation pipeline 27 during use. By connecting the tooth grooves 25 on the outer surface of the rotating plate 23 and the linkage gear 28, the rotation angle of the linkage gear 28 is the same as the rotation angle of the rotating plate 23, facilitating observation during the adjustment process and avoiding errors during adjustment, realizing the switching and use of different functions. By arranging an air delivery connecting pipeline 31 inside the inflation pipeline 27 to be connected to the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30, the anti-inhalation airbag 29 and the anti-gastric reflux airbag 30 are inflated. With the cooperation of the annular connecting pipe 32, the sector balloon 33 and the air vent hole 34, the airbag can be pre-inflated and the patient's tolerance can be tested. After the test, the airbag can be fully inflated and clamped at a specific position for use. By connecting the end of the Edi test plug 16 and the internal thread groove 38, the linkage spring 36 is pushed to contract, so that the top of the connection closing plate 37 is connected to the Edi test plug 16 and the bottom is connected to the Edi catheter 35, thereby completing the connection between the Edi catheter 35 and the Edi test plug 16 and making the inside of the Edi catheter 35 communicate with the outside world, and closing the pipe orifice when not in use.
