Technical Field

[0001] The invention relates to the technical field of cervical anastomotic fistula monitoring, and in particular to a cervical anastomotic fistula monitoring and collecting device. Background Art

[0002] The cervical esophageal cancer surgery will remove the diseased part of the patient's esophagus, and then suture the two ends of the esophagus together. Cervical anastomotic fistula is one of the sequelae that patients are prone to after esophageal cancer surgery. Once this sequelae occurs, the acid in the patient's stomach will easily overflow from the fistula at the suture position of the esophagus. The overflowing acid will contact the patient's internal organs and cause corrosion and burns, causing harm to the patient. Once the acid overflows, it will be difficult to clean up, which brings difficulties to postoperative care.

[0003] Currently, there is a lack of effective monitoring of cervical anastomotic fistula. Medical staff often cannot judge the occurrence of cervical anastomotic fistula until some time has passed based on the patient's reaction or physiological indicators.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] like Figure 1-6 As shown, the cervical anastomotic fistula monitoring and collecting device provided in this embodiment includes an elastic sleeve 1, a suction ring bag 2 and a cleaning mechanism 3.

[0035] See also Figure 1-Figure 3The elastic sleeve 1 can be made of elastic rubber or elastic plastic material to have a certain resilience. The elastic sleeve 1 is sleeve-shaped and the middle part is arched outward. One side of the elastic sleeve 1 is broken and separated so that the two ends can be closed or unfolded, and the elastic sleeve 1 can rely on its own elasticity to close the two ends in a natural state. Medical staff can use instruments to open the two ends of the elastic sleeve 1 to put it on the outside of the esophageal anastomosis. A certain space can be reserved at the middle outer arch of the elastic sleeve 1 to accommodate the acid overflowing from the esophageal fistula. The inner sides of the top and bottom edges of the elastic sleeve 1 are respectively surrounded by closed air bags 11 to seal the fitting between it and the esophagus.

[0036] like Figure 3-Figure 6 As shown, preferably, a groove 12 extending along the cross-sectional direction is provided at one end of the elastic sleeve 1, and a convex strip 13 adapted to the groove 12 is provided at the other end of the elastic sleeve 1. When the elastic sleeve 1 is not subjected to external force, the two ends are closed in a natural state so that the convex strip 13 is inserted into the groove 12, which is beneficial to improve the sealing of the joints of the ends of the elastic sleeve 1.

[0037] Furthermore, a clamping airbag 14 is wrapped around the outside of the convex strip 13, and the two ends of the clamping airbag 14 are respectively connected to two sealed airbags 11, and one of the sealed airbags 11 is connected to an inflation tube 15, and the inflation tube 15 is externally connected to an inflation device. In the process of wrapping the esophagus with the elastic sleeve 1, the sealed airbag 11 and the clamping airbag 14 are in an uninflated state, which is conducive to the installation of the elastic sleeve 1 and the closure of the two ends of the elastic sleeve 1. Then, gas can be filled into the inflation tube 15 to fill the sealed airbag 11 and the clamping airbag 14 with gas, so that the sealed airbag 11 can fit tightly against the outer wall of the esophagus. At the same time, gas is filled into the clamping airbag 14 to fill the gap between the convex strip 13 and the card slot 12, which greatly improves the sealing between the elastic sleeve 1 and the esophagus, which is conducive to preventing acid leakage.

[0038] See also Figure 1-Figure 3 The suction ring balloon 2 is arranged around the middle outer side of the elastic sleeve 1, and the inner side of the suction ring balloon 2 is evenly distributed with a plurality of suction ports 21 connected to the inner side of the elastic sleeve 1. The suction ring balloon 2 is connected to a suction tube 22, one end of the suction tube 22 is externally connected to a negative pressure device and a pH monitor 23 is installed thereon, and a monitoring probe 231 is installed on the pH monitor 23, and the monitoring probe 231 penetrates the inner side of the suction tube 22. When in use, the suction tube 22 is externally connected to a negative pressure device to provide continuous negative pressure attraction, so that the acid overflowed behind the esophageal fistula can be sucked into the suction tube 22 by each suction port 21 and the pH value change can be monitored by the monitoring probe 231 of the pH monitor 23, so that medical staff can grasp the status of the patient's esophageal anastomosis at any time, and can promptly suck away the acid behind the esophageal fistula to avoid acid retention causing damage to the patient's organs.

[0039] It should be noted that a pressure stabilizing port (not shown) is also provided on the outside of the suction ring capsule 2, and the pressure stabilizing port is connected to the outside to balance the pressure inside the suction ring capsule 2 and the inside of the elastic sheath 1, to prevent excessive negative pressure inside the elastic sheath 1, and under the negative pressure attraction of the suction tube 22, the acid liquid will not overflow from the pressure stabilizing port. Of course, for the sake of safety, a storage body with a safety function can also be provided outside the pressure stabilizing port, and a passage with multiple twists and turns can be provided in the storage body, one end of the passage is connected to the pressure stabilizing port and the other end is connected to the outside, which is conducive to further preventing the acid liquid from leaking to the outside.

[0040] Preferably, the pH monitor 23 is externally connected to an alarm, and when the pH monitor 23 detects a change in pH value, the alarm may be triggered to alert medical staff to promptly handle anastomotic fistula.

[0041] The cleaning mechanism 3 is used to clean the inner side of the elastic cover 1 .

[0042] like Figure 1-Figure 6 As shown, the cleaning mechanism 3 includes a switching component 31, a first air pipe 32, a second air pipe 33, a guide bin 34 and a scraper 35. The two guide bins 34 are respectively strip-shaped and surround the inner walls of the top and bottom ends of the elastic sleeve 1 in a circumferential direction, and the two ends are respectively located on the inner sides of the two broken ends of the elastic sleeve 1. A through groove 341 is opened on the guide bin 34 along its surrounding direction. The scraper 35 is close to the inner wall of the elastic sleeve 1, and the two ends of the scraper 35 are respectively slid through the through groove 341 to the two guide bins 34 and are provided with a through groove 341 adapted to fit the inner cavity of the guide bin 34. A push piece 351 is provided, one end of the first air pipe 32 is provided with two first branch pipes 321, and the two first branch pipes 321 are respectively connected to the same end of the two guide bins 34; one end of the second air pipe 33 is provided with two second branch pipes 331, and the two second branch pipes 331 are respectively connected to the other ends of the two guide bins 34; the other ends of the first air pipe 32 and the second air pipe 33 are respectively connected to the switching component 31, and the switching component 31 is externally connected to an inflation device for ventilating the first air pipe 32 or the second air pipe 33.

[0043] During specific use, the first air pipe 32 or the second air pipe 33 is ventilated through the switching component 31, so that the gas is transported from the first branch pipe 321 or the second branch pipe 331 to one end of the guide bin 34, and the gas will push the push piece 351 to move, so as to drive the scraper 35 to scrape along the inner wall of the elastic sleeve 1, and then scrape off the acid attached to the inner wall of the elastic sleeve 1, and make the scraped acid liquid be sucked away by each suction port 21, which is conducive to fully removing the acid liquid in the elastic sleeve 1 and avoiding excessive acid liquid from being retained in the elastic sleeve 1. When the scraper 35 moves to one end of the guide bin 34, the switching component 31 is switched to the second air pipe 33 or the first air pipe 32 for ventilation, so that the scraper 35 can be pushed to move to the other end of the guide bin 34, so that the inner wall of the elastic sleeve 1 can be cleaned reciprocatingly.

[0044] Specifically, the switching component 31 includes a connecting seat 311, a motor 312 and a connecting pipe 313. The other ends of the first air pipe 32 and the second air pipe 33 are respectively fixedly mounted on the connecting seat 311. The motor 312 is mounted on the connecting seat 311, and its output shaft end is located between the first air pipe 32 and the second air pipe 33. One end of the connecting pipe 313 is mounted on the output shaft end of the motor 312 through a bracket. The output shaft of the motor 312 rotates forward and counterclockwise to connect the connecting pipe 313 with the first air pipe 32 or the second air pipe 33. The other end of the connecting pipe 313 is connected to an external inflation device. By timing the output shaft of the motor 312 to rotate forward and reverse, ventilation can be respectively provided to the first air pipe 32 or the second air pipe 33.

[0045] Preferably, bags 342 are respectively provided on both sides of the push piece 351 in the guide bin 34, one end of the two bags 342 in the same guide bin 34 are respectively sealed and connected to the two sides of the push piece 351, and the other ends extend to the two ends of the guide bin 34 and are respectively connected to the first branch pipe 321 and the second branch pipe 331, and the gas will be pushed from the first branch pipe 321 or the second branch pipe 331 to the corresponding bag 342, and the bag 342 will expand to push the push piece 351 to move. At the same time, the bag 342 on the other side of the push piece 351 will be flattened and the internal gas will be discharged from the second air pipe 33 or the first air pipe 32, which is beneficial to prevent the gas from overflowing from the through groove 341 and causing the thrust to be reduced.

[0046] Preferably, concave surfaces are respectively provided on both sides of the scraper bar 35, and the deepest part of the concave surface is located in the middle of the scraper bar 35. When the scraper bar 35 moves, the scraped acid liquid will be driven to concentrate toward the deepest part of the concave surface on one side of its moving direction, so that the acid liquid is closer to each suction port 21, thereby improving the acid liquid cleaning effect.
