Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a single balloon catheter with a display of balloon position. Background Technology

[0002] Currently, the proportion of benign and malignant anastomotic stenosis after various cavitary resection and anastomosis surgeries remains high, especially in gastrointestinal anastomoses, small and large intestine anastomoses, choledochoenterostomy, esophagogastric anastomoses, and urinary tract anastomoses, and these are very difficult to treat. Furthermore, if the intestinal contents are not properly managed after anastomosis, excessive accumulation or rapid passage through the anastomosis can damage the site, leading to the growth of pathogenic bacteria and anastomotic infection. This hinders anastomotic healing, causing anastomotic leakage, and even extravasation of intestinal contents leading to severe abdominal and pelvic infections, threatening the patient's life.

[0003] When using traditional single-lumen balloon catheters, if medical staff do not operate them properly, the balloon is prone to displacement during use. This can lead to the accumulation of intestinal contents or rapid passage through the anastomosis, causing anastomotic infection and hindering the healing of the intestinal anastomosis. In addition, since the balloon is located inside the body, when the balloon is displaced, medical staff cannot clearly observe its position. Summary of the Invention

[0004] This invention provides a single balloon catheter with a balloon position display function to at least solve some of the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0030] like Figure 1-7As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0031] The present invention has a support tube placed inside the intestine and located upstream of the intestinal anastomosis. A double-lumen catheter 1 is placed inside the support tube, and an airbag 2 for sealing the inner wall of the support tube is sealed on the outer wall of the double-lumen catheter 1. The delivery mechanism is connected to the airbag 2 through the double-lumen catheter 1. At the same time, a display mechanism is set on the double-lumen catheter 1 and the airbag 2. The display mechanism can determine whether the airbag 2 has shifted during use.

[0032] In use, medical staff place the double-lumen catheter 1 inside the support tube. The delivery mechanism delivers gas to the balloon 2 through the double-lumen catheter 1. During the inflation process, the outer wall of the balloon 2 is tightly attached to the inner wall of the support tube and seals the support tube, allowing intestinal contents to be discharged through the double-lumen catheter 1, thereby preventing intestinal contents from contaminating the anastomosis. At the same time, the X-ray display mechanism can display the position of the balloon 2, thereby preventing the balloon 2 from sliding on the double-lumen catheter 1. Example

[0033] like Figure 1-7 As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0034] The display mechanism includes a contrast ring A3 located on the outer wall of the double-lumen catheter 1 and at both ends of the airbag 2, and two contrast rings B4 located on the outer walls of both ends of the airbag 2.

[0035] This embodiment 2 provides a more preferred structure for the display mechanism based on embodiment 1. Specifically, the display mechanism includes a radiopaque ring A3 disposed on the outer wall of the double-lumen catheter 1 and located at both ends of the airbag 2, and two radiopaque rings B4 disposed at both ends of the airbag 2.

[0036] In this invention, two imaging rings A3 are installed on the outer wall of the double-lumen catheter 1, and the two imaging rings A3 are located at both ends of the balloon 2. At the same time, an imaging ring B4 is provided on the outer wall of both ends of the balloon 2. When the balloon 2 is displaced, the two imaging rings B4 on the outer wall of both ends of the balloon 2 move synchronously with the balloon 2. Under the irradiation of X-rays, the distance between the imaging ring B4 and the imaging ring A3 will change, which makes it easier for medical staff to observe whether the balloon 2 has been displaced.

[0037] When this invention is used, under X-ray irradiation, if the distance between the corresponding imaging rings A3 on both sides of the airbag 2 is consistent, then the airbag 2 has not shifted. If the distance between one imaging ring A3 and one of the imaging rings B4 on one side of the airbag 2 becomes longer or shorter, and the distance between the imaging ring A3 and the other imaging ring B4 on the other side of the airbag 2 becomes shorter or longer, then the airbag 2 has shifted, thus making it easier for medical personnel to determine whether the airbag 2 has shifted.

[0038] Both the developing ring A3 and the developing ring B4 of this invention are made of barium material. Example

[0039] like Figure 1-7 As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0040] The display mechanism includes a contrast ring A3 located on the outer wall of the double-lumen catheter 1 and at both ends of the airbag 2, and two contrast rings B4 located at both ends of the airbag 2.

[0042] This embodiment 3 provides a more preferred structure for the double-lumen catheter 1 based on embodiment 2. Specifically, the outer wall of the double-lumen catheter 1 is provided with an installation ring groove 5 that is adapted to the imaging ring A3, and the imaging ring A3 is installed in the installation ring groove 5.

[0043] The mounting groove 5 of this utility model is set on the outer wall of the double-lumen conduit 1. The mounting groove 5 facilitates the installation of the developing ring A3 and prevents the developing ring A3 from sliding. Example

[0044] like Figure 1-7As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0046] The outer wall of the airbag 2 is provided with a developing installation groove 6 that is adapted to the developing ring B4, and the developing ring B4 is installed in the developing installation groove 6.

[0047] This embodiment 4 provides a more preferred structure for the airbag 2 based on embodiment 2. Specifically, the outer wall of the airbag 2 is provided with a developing installation groove 6 that is adapted to the developing ring B4, and the developing ring B4 is installed in the developing installation groove 6.

[0048] The developing installation groove 6 of this utility model is set on the outer wall of the air bag 2. The developing installation groove 6 facilitates the installation of the developing ring A3, and at the same time, the developing installation groove 6 can prevent the developing ring B4 from sliding after installation. Example

[0049] like Figure 1-7 As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0050] The double-lumen catheter 1 is equipped with a drainage tube 7 and a medium delivery tube 8 that are not connected to each other. The two ends of the medium delivery tube 8 are respectively sealed to the airbag 2 and the delivery mechanism. The double-lumen catheter 1 is equipped with a drainage hole 9 that is connected to the drainage tube 7.

[0051] Based on Example 1, Example 5 provides a more preferred structure for the double-lumen catheter 1. Specifically, the double-lumen catheter 1 is provided with a drainage tube 7 and a medium delivery tube 8 that are not connected to each other. The two ends of the medium delivery tube 8 are respectively sealed and connected to the airbag 2 and the delivery mechanism. The double-lumen catheter 1 is provided with a drainage hole 9 that is connected to the drainage tube 7.

[0052] The drainage tube 7 of this utility model facilitates the drainage of intestinal contents. The double-lumen catheter 1 is provided with a drainage hole 9 that communicates with the drainage tube 7. During use, the intestinal contents enter the drainage tube 7 through the drainage hole 9, thereby facilitating the drainage of intestinal contents. At the same time, the drainage tube 7 can prevent intestinal contents from contaminating the anastomosis. Meanwhile, one end of the medium delivery tube 8 is sealed to the delivery mechanism, and the other end is connected to the air bag 2. During use, the delivery mechanism delivers gas to the air bag 2 through the medium delivery tube 8. The air bag 2 inflates, thereby sealing the outer wall of the air bag 2 with the inside of the support tube, thus preventing intestinal contents from contaminating the anastomosis. Example

[0053] like Figure 1-7 As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0054] The double-lumen catheter 1 is equipped with a drainage tube 7 and a medium delivery tube 8 that are not connected to each other. The two ends of the medium delivery tube 8 are respectively sealed to the airbag 2 and the delivery mechanism. The double-lumen catheter 1 is equipped with a drainage hole 9 that is connected to the drainage tube 7.

[0055] The medium delivery pipe 8 is provided with a medium inlet / outlet port 10 that communicates with the airbag 2.

[0056] This embodiment 6 provides a more preferred structure for the medium delivery pipe 8 based on embodiment 5, specifically: the medium delivery pipe 8 is provided with a medium inlet / outlet hole 10 that communicates with the airbag 2.

[0057] The present invention has a medium delivery tube 8 with a medium inlet / outlet hole 10 connected to the airbag 2. The medium inlet / outlet hole 10 is located on the medium delivery tube 8 and inside the airbag 2. In use, the delivery mechanism delivers gas into the medium delivery tube 8. The gas in the medium delivery tube 8 enters the airbag 2 through the medium inlet / outlet hole 10. The airbag 2 inflates, thereby sealing the outer wall of the airbag 2 with the inside of the support tube, thus preventing intestinal contents from contaminating the anastomosis. After use, the gas in the airbag 2 is sucked out by the delivery mechanism, which facilitates the removal of the double-lumen catheter 1. Example

[0058] like Figure 1-7As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0059] The delivery mechanism includes a delivery tube 11 that is sealed to the double-lumen catheter 1, a Luer connector 12 located at one end of the delivery tube 11, and an indicator balloon 13 that is sealed to and connected to the delivery tube 11.

[0060] This embodiment 7 provides a more preferred structure for the delivery mechanism based on embodiment 1. Specifically, the delivery mechanism includes a delivery tube 11 that is sealed and connected to the double-lumen catheter 1, a Luer connector 12 located at one end of the delivery tube 11, and an indicator balloon 13 that is sealed on the delivery tube 11 and connected to the delivery tube 11.

[0061] The present invention relates to a delivery tube 11 that is sealed to a media delivery tube 8, and one end of the delivery tube 11 is provided with a Luer connector 12. In use, medical personnel inject gas into the delivery tube 11 through the Luer connector 12 using a syringe. The gas in the delivery tube 11 enters the airbag 2 through the media delivery tube 8 and the media inlet / outlet port 10, causing the airbag 2 to inflate and seal the support tube. Simultaneously, the delivery tube 11 is provided with an indicator balloon 13 connected to the media delivery tube 8. The indicator balloon 13 allows medical personnel to easily determine whether there is a leak in the airbag 2. Medical staff inject gas into the delivery tube 11 through the Luer connector 12 using a syringe. Part of the gas in the delivery tube 11 enters the indicator balloon 13, causing the indicator balloon 13 to inflate. The other part of the gas enters the airbag 2 through the medium delivery tube 8 and the medium inlet / outlet port 10, causing the airbag 2 to inflate. When the airbag 2 leaks during use, the gas in the indicator balloon 13 will also leak along with the airbag 2, causing the indicator balloon 13 to deflate. By observing the state of the indicator balloon 13, medical staff can easily determine whether the airbag 2 is leaking. Example

[0062] like Figure 1-7As shown, the present invention provides a single balloon catheter with a balloon position display, including a support tube fixed in the intestine and located upstream of the intestinal anastomosis, a double-lumen catheter 1 disposed in the support tube for the discharge of intestinal contents, a balloon 2 disposed on the double-lumen catheter 1 and sealed to the inner wall of the support tube after inflation, a delivery mechanism connected to the double-lumen catheter 1 and communicating with the balloon 2 through the double-lumen catheter 1 for the delivery of gas, and a display mechanism disposed on the double-lumen catheter 1 and the balloon 2 respectively for displaying the position of the balloon 2.

[0063] The delivery mechanism includes a delivery tube 11 connected to the double-lumen catheter 1, a Luer connector 12 located at one end of the delivery tube 11, and an indicator balloon 13 sealed on and connected to the medium delivery tube 8.

[0064] The delivery pipe 11 has a medium inlet hole 14 that communicates with the indicator balloon 13.

[0065] This embodiment 8 provides a more preferred structure for the delivery pipe 11 based on embodiment 7, specifically: the delivery pipe 11 is provided with a medium inlet hole 14 that communicates with the indicator balloon 13.

[0066] The medium inlet hole 14 of this utility model is opened on the delivery pipe 11 and located in the indicator balloon 13. In use, the gas in the delivery pipe 11 can enter the indicator balloon 13 through the medium inlet hole 14, so that the indicator balloon 13 is connected to the airbag 2 through the medium inlet hole 14, the delivery pipe 11, the medium delivery pipe 8 and the medium inlet / outlet hole 10, so that the indicator balloon 13 can judge the state of the airbag 2.

[0069] This embodiment 9 provides a more preferred structure for the connector 15 based on embodiment 1. Specifically, it also includes a connector 15 installed on the double-lumen catheter 1. The connector 15 includes a connecting tube 16 installed on the double-lumen catheter 1 and a guide tube 17 connected to the connecting tube 16. The connecting tube 16 and the guide tube 17 are an integral structure.

[0070] The connector 15 of this utility model facilitates the sealed connection between the delivery tube 11 and the medium delivery tube 8, and allows the delivery tube 11 to be located outside the human body, thereby facilitating the delivery of gas. Specifically, the connecting tube 16 is installed on the outer wall of the double-lumen catheter 1, and the inner diameter of the connecting tube 16 is consistent with that of the drainage tube 7, thereby preventing the end face of the connecting tube 16 from blocking the intestinal contents after the connection between the connecting tube 16 and the double-lumen catheter 1. At the same time, the guide tube 17 is set at one end of the connecting tube 16, thereby facilitating the guidance of the intestinal contents in the connecting tube 16 and facilitating the discharge of the intestinal contents. Furthermore, the delivery tube 11 is connected to the medium delivery tube 8 through the connecting tube 16, thereby facilitating the delivery of gas by the delivery tube 11.
