Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a balloon catheter with a flushing structure. Background Technology

[0002] If the contents of the intestines are not properly managed after anastomosis, excessive accumulation or rapid passage of contents through the anastomosis can damage the anastomosis. The growth of pathogenic bacteria can lead to anastomotic infection, hindering the healing of the intestinal anastomosis, causing anastomotic leakage, or even leakage of intestinal contents leading to severe abdominal and pelvic infections, which can threaten the patient's life.

[0003] Traditionally, after the intestinal lesion is removed, it is sutured to the anastomosis site using a blocker. At the same time, a balloon catheter is placed inside the blocker to block the intestinal contents and prevent them from passing through the anastomosis. After the anastomosis heals, the balloon catheter is pulled out through the anus. During the healing process, the anastomosis may become purulent or have natural intestinal secretions attached to it. If the purulent areas or natural intestinal secretions are not flushed, it may affect the patient's anastomosis recovery. Utility Model Content

[0029] Example 1.

[0030] like Figure 1-7As shown, the present invention provides a balloon catheter with a flushing structure, including a stopper fixed to the front end of the anastomosis, a catheter 1 disposed in the stopper for the discharge of intestinal contents, a balloon 2 disposed on the outer wall of the catheter 1 and sealed to the inner wall of the stopper after expansion, a medium delivery mechanism connected to the catheter 1 and connected to the balloon 2 for the delivery of medium, and a flushing mechanism connected to the catheter 1 and flushing the intestinal anastomosis through the catheter 1.

[0031] This invention relates to a blocking device fixed at the anastomosis end. A catheter 1 is placed inside the blocking device, allowing intestinal contents to drain out of the body without affecting intestinal patency. A balloon 2 is mounted on the outer wall of the catheter 1. A media delivery mechanism is connected to the catheter 1 and delivers media to the balloon 2 through the catheter 1, causing the balloon 2 to inflate. Once inflated, the balloon 2 seals against the inner wall of the blocking device, thus blocking the intestinal contents from flowing through the anastomosis, protecting the anastomosis, promoting healing, and reducing the incidence of anastomotic complications. A flushing mechanism is connected to the catheter 1 and delivers flushing media into the intestine through the catheter 1, flushing the intestinal anastomosis to prevent residual intestinal secretions and pus, facilitating post-anastomosis healing, and reducing the risk of anastomotic infection. The flushing media used in this invention is preferably penicillin, and the media delivered by the media delivery mechanism is preferably a fluid, preferably pure water, an inert gas, or air.

[0032] In use, the media delivery mechanism and flushing mechanism are connected to the catheter 1. The balloon 2 is inserted into the blocker. The media delivery mechanism delivers the media into the balloon 2 through the catheter 1, causing the balloon 2 to inflate. After inflation, the outer wall of the balloon 2 seals with the inner wall of the blocker, thereby blocking the intestinal contents. When suppuration or intestinal secretions occur at the anastomosis, the flushing mechanism sprays the flushing medium onto the anastomosis through the catheter 1, thereby flushing the anastomosis and preventing intestinal pus or secretions from adhering to the anastomosis and affecting its healing.

[0033] Example 2.

[0034] like Figure 1-7 As shown, the present invention provides a balloon catheter with a flushing structure, including a stopper fixed to the front end of the anastomosis, a catheter 1 disposed in the stopper for the discharge of intestinal contents, a balloon 2 disposed on the outer wall of the catheter 1 and sealed to the inner wall of the stopper after expansion, a medium delivery mechanism connected to the catheter 1 and connected to the balloon 2 for the delivery of medium, and a flushing mechanism connected to the catheter 1 and flushing the intestinal anastomosis through the catheter 1.

[0035] The catheter 1 has a drainage cavity 5, a media delivery cavity 6 and a flushing cavity 7 that are not interconnected. The media delivery cavity 6 is sealed to the media delivery mechanism and the flushing cavity 7 is sealed to the flushing mechanism.

[0036] The drainage lumen 5, media delivery lumen 6, and flushing lumen 7 of this invention are all located inside the catheter 1, and are not interconnected. The drainage lumen 5 facilitates the drainage of intestinal contents to the outside without affecting the patency of the intestines. The media delivery lumen 6 is sealed to the media delivery mechanism, which delivers the media to the balloon 2 through the media delivery lumen 6, causing the balloon 2 to inflate and seal against the inner wall of the blocker after inflation. The flushing lumen 7 is sealed to the flushing mechanism, which sprays the flushing media onto the anastomosis through the flushing lumen 7, thereby achieving flushing of the anastomosis.

[0037] Example 3.

[0038] like Figure 1-7 As shown, the present invention provides a balloon catheter with a flushing structure, including a stopper fixed to the front end of the anastomosis, a catheter 1 disposed in the stopper for the discharge of intestinal contents, a balloon 2 disposed on the outer wall of the catheter 1 and sealed to the inner wall of the stopper after expansion, a medium delivery mechanism connected to the catheter 1 and connected to the balloon 2 for the delivery of medium, and a flushing mechanism connected to the catheter 1 and flushing the intestinal anastomosis through the catheter 1.

[0040] The flushing mechanism includes a flushing pipe 3, one end of which is sealed and connected to the flushing cavity 7 and the other end of which is connected to an external flushing device, and a flushing hole 15 located on the outer wall of the conduit 1 and connected to the flushing cavity 7; the flushing hole 15 is located on one side of the balloon 2.

[0041] The flushing tube 3 of this invention is sealed at one end to the flushing cavity 7 and connected to an external flushing device at the other end. At the same time, the outer wall of the conduit 1 is provided with a flushing hole 15 that communicates with the flushing cavity 7. In use, the external flushing device delivers the flushing medium to the flushing cavity 7 through the flushing tube 3. Under pressure, the flushing medium in the flushing cavity 7 is sprayed out from the flushing hole 15 and sprayed onto the anastomosis, thereby preventing intestinal pus or intestinal secretions from adhering to the anastomosis.

[0042] The flushing hole 15 of this utility model is located on one side of the balloon 2. Specifically, the position of the flushing hole 15 can be selected according to the needs, so as to select the appropriate position of the flushing hole 15 according to the anastomosis of the patient's anastomosis, thereby facilitating flushing after anastomosis.

[0046] The medium conveying mechanism includes a conveying pipe 18, one end of which is sealed and connected to the medium conveying cavity 6, and the other end is connected to a Luer connector 9.

[0047] One end of the delivery tube 18 of this utility model is sealed and connected to the medium delivery tube cavity 6, and the other end is connected to the Luer connector 9. Specifically, the Luer connector 9 is connected to an external syringe. In use, the syringe contains a medium. Pushing the syringe, the medium in the syringe enters the balloon 2 through the delivery tube 18, causing the balloon 2 to inflate. After the balloon 2 inflates, the outer wall of the balloon 2 seals with the inner wall of the blocker. After the anastomosis heals, by pulling the syringe, the syringe draws out the medium in the balloon 2 through the delivery tube 18, causing the balloon 2 to fold, thereby facilitating the extraction of the catheter 1 and the balloon 2 from the anus to the outside of the body.

[0052] The connector 10 of this invention is disposed on the catheter 1. The connector 10 facilitates the drainage of intestinal contents to the outside. The conduit A11 is disposed on the connector 10 and is adapted to the media delivery mechanism. The media delivery mechanism is sealed inside the conduit A11 and is sealed to the media delivery cavity 6. The conduit A11 facilitates the connection between the delivery pipe 18 and the media delivery cavity 6, thereby facilitating the delivery of the media. The conduit B12 is disposed on the connector 10 and is adapted to the flushing mechanism. The flushing mechanism is sealed inside the conduit B12 and is sealed to the flushing cavity 7. The conduit B12 facilitates the connection between the flushing cavity 7 and the flushing pipe 3, thereby facilitating the flushing medium to flush the anastomosis through the flushing pipe 3 and the flushing cavity 7.

[0053] This invention also makes it easier to distinguish between the flushing pipe 3 and the delivery pipe 18 by changing the color of the conduit A11 and the conduit B12, thus facilitating operation by nursing staff.

[0077] Working principle

[0078] In use, the syringe contains a medium. Pushing the syringe allows the medium to enter the balloon 2 through the delivery tube 18 and delivery hole 17, causing the balloon 2 to inflate. Once inflated, the outer wall of the balloon 2 seals against the inner wall of the blocker. When suppuration occurs at the anastomosis site or intestinal secretions adhere to the anastomosis site, an external flushing device delivers flushing medium through the flushing tube 3 to the flushing chamber 7. Under pressure, the flushing medium in the flushing chamber 7 is ejected from the flushing hole 15, spraying onto the anastomosis site to flush the intestinal pus or intestinal secretions. After the anastomosis heals, pulling the syringe draws out the medium from the balloon 2 through the delivery tube 18 and delivery hole 17, causing the balloon 2 to fold, thus facilitating the removal of the catheter 1 and balloon 2 from the anus.

[0079] The syringe, Luer connector 9, and rinsing device used in this invention are all existing technologies and can be purchased and used directly on the market. Therefore, the structure, circuit, and principle of the syringe, Luer connector 9, and rinsing device will not be described in detail here.
