[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1 to 5 As shown in the illustration, this application provides an intestinal obstruction catheter kit, comprising: a catheter 1, a balloon 2, a drug supply connector 3, a suction connector 4, and an air inlet connector 5. The catheter 1 has a suction channel 13, a drug supply channel 14, and an air inlet channel 15, all extending along the length of the catheter 1. The suction channel 13 and the drug supply channel 14 are isolated from each other. The balloon 2 is fitted onto the catheter 1 and communicates with the air inlet channel 15. The drug supply connector 3 is connected to the catheter 1 and communicates with the drug supply channel 14. The drug supply connector 3 is used to connect a drug delivery device for injecting medication, such as a nutrient solution, into the patient's intestines. The suction connector 4 is connected to the catheter 1 and communicates with the suction channel 13. The suction connector 4 can be used to connect a negative pressure device to draw substances from the patient's intestines to relieve symptoms. An air inlet connector 5 is connected to the catheter 1 and communicates with the air inlet channel 15 for inflating the balloon 2 with air, causing the balloon to expand. The balloon is mainly used to fix the position of the catheter 1 (to prevent slippage) or to close the intestinal lumen (such as for decompression during the treatment of intestinal obstruction). In simple decompression mode, the balloon 2 may be inflated to assist in stabilizing the catheter 1.

[0022] The catheter 1 of this application has a drug supply channel 14, which is isolated from the suction channel 13, thus solving the problem of cross-infection in clinical practice. The intestinal obstruction catheter kit of this application supports simultaneous drug administration for intestinal obstruction and aspiration of foreign objects in the intestine, which is beneficial for accurately, safely and quickly resolving intestinal obstruction problems.

[0023] In some possible implementations, the intestinal obstruction catheter kit includes a balloon 2 and two inlet connectors 5, both connected to an inlet channel 15. The two inlet structures can be Y-shaped. One inlet connector 5 is used to supply air to the inlet channel, connecting to an inlet device to rapidly inject gas into the balloon 2, causing it to inflate. The other inlet connector 5 is used to inflate the inlet channel 15. As the balloon 2 is compressed within the intestine, the gas content decreases over time, leading to reduced inflation. Therefore, the inlet connector 5 needs to slowly inflate the inlet channel 15 to maintain the balloon 2 at the required inflation level. The inlet connector 5 can be equipped with a one-way valve, allowing gas to enter only one side of the inlet channel 15 and preventing the gas from being expelled, thus avoiding rapid deflation and flattening of the balloon.

[0024] In some possible implementations, such as Figure 5 As shown, the catheter 1 can be a one-piece molded component. The catheter 1 has an outer tube 11 and an inner septum 12. The inner septum 12 is located inside the outer tube 11 and is connected to opposite sides of the inner wall of the outer tube 11. The inner septum 12 divides the interior of the outer tube 11 to form the suction channel 13 and the drug supply channel 14. The cross-sections of both the suction channel 13 and the drug supply channel 14 are approximately semi-circular. The cross-section of the suction channel 13 is slightly larger than that of the drug supply channel 14. The intestinal obstruction catheter kit also includes a guidewire assembly 8 (described in detail below). The slightly larger cross-section of the suction channel 13 allows the guidewire assembly 8 to be easily inserted into the suction channel 13 to adjust the bending direction of the guidewire tip. The drug supply channel 14 can inject medication into the patient's intestines; for example, the medication can dissolve hard objects in the intestines. Simultaneously, the suction channel 13 can extract the dissolved substances. The arrangement of the suction channel 13 and the drug supply channel 14 reduces the risk of cross-infection. The catheter 1 of this application is not formed by nesting inner and outer tubes. The catheter 1 of this application can be an integrally molded part formed by injection molding. The suction cavity 13 and the drug supply cavity 14 are formed on the left and right sides of the interior, respectively. The manufacturing process is simple, the structure is strong, it is not easy to have leakage problems, and it has good durability.

[0025] In some possible implementations, the inner septum 12 or the outer tube 11 has a thickened section on which the air inlet channel 15 is provided. The inner diameter of the air inlet channel 15 is smaller than the inner diameter of the suction channel 13 and the drug supply channel 14. Most of the space inside the catheter 1 is used to form the suction channel 13 and the drug supply channel 14. In order to provide a smaller air inlet channel 15, a local solid part inside the catheter can be thickened to form a thickened section. The air inlet channel 15 has a small aperture and can be provided on the thickened section. The air inlet channel 15 is isolated from the suction channel 13 and the drug supply channel 14, respectively. For example, at the location where the outer tube 11 and the inner spacer 12 connect, the solid structure is relatively large and can be appropriately thickened to form a thickened section, which facilitates the installation of the air inlet channel 15. This structural design also helps to strengthen the structural strength of the transition part between the outer tube 11 and the inner spacer 12, improving the durability of the catheter 1. Moreover, the design structure of the air inlet channel 15 is simple and does not affect the arrangement of the suction channel 13 and the drug supply channel 14.

[0026] In some possible implementations, such as Figure 2 As shown, a suction port 113 is provided on the side wall of the catheter 1 away from the drug supply connector 3, and the suction port 113 connects to the suction cavity 13. It should be noted that one or more suction ports 113 can be provided. The suction port 113 can be located on the side wall of the end of the catheter 1, avoiding the placement of the camera 61. The suction port 113 can also be located on either side of the balloon 2. It should be noted that the catheter 1 can have one or multiple suction ports 113, and the placement of the suction port 113 can be varied. For example, in addition to providing a suction port 113 on the side wall of the catheter 1 near the end, depending on clinical application needs, suction ports 113 can also be intermittently distributed between the front and rear ends of the balloon 2 to promptly aspirate any refluxed foreign matter and prevent complications caused by reflux.

[0027] In some possible implementations, the intestinal obstruction catheter kit includes a camera assembly 6 connected to the catheter 1, the camera assembly 6 having a camera 61 located at the end of the catheter 1.

[0028] By installing a camera 61 on the intestinal obstruction catheter 1, real-time images of the intestinal tract can be transmitted, helping doctors to visually observe the path of the catheter 1 and accurately locate the obstruction site. Traditional X-ray or endoscopic guidance requires external equipment, while this application, by embedding a camera 61 on the catheter 1, can directly display the contact between the tip of the catheter 1 and the intestinal wall, reducing the risk of misinsertion.

[0029] When the drug is injected into the intestine through the drug outlet 112, the changes in the substances in the intestine can be observed with the help of the camera 61. When foreign objects are found to be dissolved in the intestine, the intestinal obstruction catheter kit can be controlled to perform a suction operation, so that the dissolved foreign objects are suctioned out of the human intestine through the suction channel.

[0030] like Figure 3 As shown, the suction port 113 of the catheter 1 with camera 61 is located on the side of camera 61. The suction port 113 can be used to accurately extract test specimens from obstructions. Camera 61 can accurately identify the shape and severity of the obstruction and provide a direct visual representation to the clinic, facilitating precise medication and treatment to meet clinical needs.

[0031] In some possible implementations, such as Figure 3 As shown, a drug outlet 112 is provided on the end face of the catheter 1. The drug outlet 112 is connected to the drug supply cavity 14. The camera 61 is provided on the end face and is offset from the drug outlet 112.

[0032] Multiple drug outlets 112 can be provided on the catheter 1, with each outlet 112 spaced apart sequentially along the length of the catheter 1. This allows for the rapid delivery of medication to multiple sites in the rectum, accelerating drug absorption and improving therapeutic efficacy. Of course, the drug supply cavity 14 can also be used to supply water and nutrients to the intestines, which is beneficial for restoring the patient's strength and maintaining vital signs.

[0033] In this embodiment, a drug outlet 112 is provided on the end face of the catheter 1, and the drug outlet 112 and the camera 61 are offset from each other so that they do not interfere with each other. The close proximity of the drug outlet 112 and the camera 61 facilitates precise drug administration. By placing both the camera 61 and the drug outlet 112 at the end of the tube body, this application makes full use of the space at the end of the catheter, resulting in a more reasonable structural design.

[0034] In some possible implementations, such as Figure 3 As shown, the area of ​​the end face of the catheter 1 is larger than the cross-sectional area of ​​the camera 61. The camera 61 is located on the side of the end face corresponding to the suction channel 13. An arc-shaped step surface is formed between the camera 61 and the end face, and the drug outlet 112 is disposed on the arc-shaped step surface. The camera 61 is located on the side of the end face corresponding to the suction channel 13, while a drug outlet 112 is disposed on the end face corresponding to the position of the drug supply channel 14. The extension direction of the drug outlet 112 and the drug supply channel 14 is smoothly transitioned, that is, the end of the drug supply channel 14 is straight, thereby reducing fluid flow resistance and facilitating rapid drug administration.

[0035] Optionally, such as Figure 1 and Figure 5As shown, the camera assembly 6 includes a cable 62. A lead wire groove 111 is provided on the outer wall of the conduit 1. The lead wire groove 111 extends along the length direction of the conduit 1. The cable 62 is embedded in the lead wire groove 111 and the cable 62 is fixed to the conduit 1. One end of the cable 62 is connected to the camera 61, and the other end of the cable 62 is connected to a camera data connector 63.

[0036] The camera 61 can be bonded to the end of the conduit 1 with liquid silicone. Afterwards, the camera 61 and the conduit 1 can be heat-fused and fixed with the same material (such as the same material as the conduit 1) through high temperature treatment, so that the camera 61 and the conduit have an integrated appearance.

[0037] like Figure 5 As shown, in this embodiment, a lead-wire groove 111 is formed on the outer wall of the conduit 1. The lead-wire groove 111 has an open structure, and its inner diameter roughly matches the outer diameter of the cable 62 of the camera assembly 6. The lead-wire groove 111 is exposed, allowing the cable 62 to be embedded within it during camera assembly. The cable 62 can be bonded to the inner wall of the lead-wire groove 111 using an adhesive. The adhesive fills the gap between the cable 62 and the lead-wire groove 111, ensuring a smooth transition between the outer surface of the cable 62 and the outer surface of the conduit 1, avoiding sharp edges. The adhesive can be liquid silicone.

[0038] In some possible implementations, the intestinal obstruction catheter kit includes a guidewire assembly 8, which includes an operating handle 81 and a guidewire body connected to the operating handle 81. The operating handle 81 is disposed at one end of the guidewire body, and the operating handle 81 and the guidewire body are in a driving engagement to drive the end of the guidewire body to bend and deform, so that the guidewire body can be inserted into the suction cavity 13.

[0039] The guidewire assembly 8 of this application has a structure and principle similar to that of a gastrointestinal endoscope. The bending deformation of its end can be adjusted using the operating handle 81. However, the outer diameter of the guidewire assembly 8 in this application is smaller, much smaller than that of a gastrointestinal endoscope, allowing it to be inserted into the suction cavity 13, so that the end of the guidewire body is located at or near the end of the suction cavity 13. With the help of the camera 61 and screen feedback, the doctor can instantly adjust the bending deformation direction of the end of the guidewire body, that is, adjust the bending angle of the catheter 1 end, achieving precise insertion and avoiding mechanical damage to the fragile intestinal wall, especially suitable for tortuous or severely adhered small intestinal segments. The visualization technology of the guidewire assembly 8 and the camera 61 reduces repeated attempts, shortens insertion time, improves medical efficiency, reduces patient treatment time, and the precise operation reduces nausea and vomiting caused by repeated insertion, significantly improving patient tolerance. The intestinal obstruction catheter kit with its built-in camera 61 and adjustable guidewire assembly 8 achieves a leap from "blind operation" to "visualized precision treatment" through "eye-hand synchronization" technology, making it particularly suitable for complex or high-risk cases. In this application, the guide wire assembly 8 can be a mature product provided in the prior art. This application does not need to improve its structure. It only needs to have an outer diameter smaller than the inner diameter of the suction cavity 13 of this application.

[0040] The guidewire assembly 8 can move 360 ​​degrees. By operating the operating handle 81, the bending direction of the catheter 1 can be adjusted to quickly resolve problems such as the front end of the catheter 1 being stuck at the pylorus, intestinal mucosal folds, or small intestinal loops. Guided by the guidewire assembly 8, it is pushed towards the anus with intestinal peristalsis and placed at the site of the obstruction.

[0041] It should be noted that the length of the guidewire body can be limited to no more than the length of the suction cavity 13, so that the end of the guidewire body will not protrude from the suction cavity 13 after being inserted into it, that is, it will not come into contact with the patient's intestinal wall, thus improving safety.

[0042] In some possible implementation schemes, combined Figures 1 to 3 As shown, the intestinal obstruction catheter kit includes a sensor assembly 7. The sensor of the sensor assembly 7 is located at the end of the catheter 1 opposite to the suction connector 4, that is, the sensor of the sensor assembly 7 is located at the front end of the catheter 1, but behind the camera. The sensor assembly 7 can also be located between the camera 61 and the end face of the catheter end to form an arc-shaped step surface. There is a gap between the sensor assembly 7 and the suction port 113. The sensors of the sensor assembly 7 include a temperature sensor and a pressure sensor.

[0043] By incorporating pressure sensors, pressure changes at the obstruction site within the intestine can be monitored in real time, helping doctors assess intestinal function and adjust treatment plans. Monitoring data can prevent complications such as intestinal perforation, ensuring safe and effective treatment and improving diagnostic and treatment accuracy. Temperature sensors detect changes in intestinal temperature, indirectly reflecting intestinal blood supply and peristaltic function. Combined analysis of pressure data can determine whether intestinal patency has been restored or if other pathological changes exist. Sensor data provides a basis for clinical decision-making, such as adjusting drainage rate and nutrient solution ratio, avoiding abdominal pain or tissue damage caused by sudden pressure changes, and promoting rapid patient recovery. The pressure and temperature sensors can be integrated to reduce size and fully utilize the space of catheter 1. For example, a groove can be provided on the end face of catheter 1, housing both the pressure and temperature sensors. The groove needs to be offset from the suction port 113 and camera 61, thus making full use of the limited space at the end of catheter 1.

[0044] A lead-wire cavity 16 with a small inner diameter can be provided inside the conduit. The sensor assembly 7 also includes a wire 71, which can be inserted into the lead-wire cavity 16. One end of the wire 71 is connected to the sensor assembly 7, and the other end extends out of the conduit 1 and is connected to a sensor data connector 72. The lead-wire cavity 16 can be provided on the thickened section.

[0045] In some possible implementations, the intestinal obstruction catheter kit may further include an end housing 9 disposed at the end of the catheter 1 opposite to the camera 61. The drug supply connector 3, suction connector 4, and air inlet connector 5 are all connected to the end housing 9.

[0046] An extension groove 91 can be formed on the surface of the end housing 9, which can serve as a cavity for the camera cable. The cable 62 connecting the camera 61 can extend along the extension groove 91 and eventually protrude from its end, connecting to a camera data connector 63 at its end. The camera data connector 63 can be a Type-C interface or a USB interface; this application does not limit the specific type of the camera data connector 63. The cable 62 can be bonded to the extension groove 91 with adhesive. Extension grooves 91 can be provided on both sides of the housing, allowing the cable 62 and the wire 71 connecting the sensor assembly 7 to extend out of the end housing 9 along their respective extension grooves 91. The extension groove 91 is an exposed groove on the surface of the end housing 9, and its structural design facilitates the rapid assembly of wires and cables.

[0047] In some possible implementations, such as Figure 4As shown, multiple gravity balls 10 can be installed at the end of catheter 1 opposite to the drug supply connector 3. The gravity balls 10 are located behind the camera 61, and each gravity ball 10 is arranged sequentially along the length of catheter 1. The gravity balls 10 at the front of catheter 1 in the intestinal obstruction catheter kit are mainly used for guidance and positioning to help the doctor accurately reach the target location during catheter placement. The gravity balls 10 are usually designed to be soft and smooth, which helps reduce friction on intestinal tissue, thereby reducing the risk of injury. At the same time, it provides a way for the doctor to more easily manipulate and navigate the intestinal obstruction catheter. During catheter placement, the presence of the gravity balls 10 at the front also helps maintain the stability of the intestinal obstruction catheter. Once placed, its specific shape helps reduce the possibility of movement or dislodgement. This is crucial for maintaining an effective treatment process. With the design and function of the front ball, the intestinal obstruction catheter can be placed more accurately and safely, improving treatment effectiveness and reducing related risks.

[0048] In some possible implementations, such as Figure 4 As shown, two balloons 2 can be installed on catheter 1, namely an anterior balloon 2 and a posterior balloon 2. The anterior balloon 2, when inflated, acts as a "weight," helping catheter 1 pass through the pylorus or intestinal bends, gradually advancing to the obstruction site using intestinal peristalsis. The posterior balloon 2, when inflated, stabilizes the position of catheter 1, preventing slippage. Simultaneously, the alternating inflation and deflation of the posterior balloon allows for synchronized movement of catheter 1 and the intestine, reducing damage to the intestinal wall. Its principle is similar to inchworm movement. The double-balloon design allows for smooth passage through narrowed areas even under strong intestinal obstruction pressure resistance. The double-balloon design allows for more precise positioning of the obstruction site, improving drainage efficiency and reducing intestinal pressure. In some possible implementations, catheter 1, balloon 2, and all connectors can be made of antibacterial silicone and / or antibacterial polyurethane materials, which have excellent antibacterial effects and provide sustained antibacterial activity from day 1 to day 30. The main antibacterial species are Escherichia coli and Staphylococcus aureus, with an antibacterial effect of over 99%.

[0049] The intestinal obstruction catheter kit provided in this application embodiment has a camera 61, a temperature sensor, and a pressure sensor. It supports full-process visual monitoring of intestinal changes to avoid complications such as perforation, while continuously monitoring intestinal pressure and temperature to provide clinical evidence of the effectiveness of clinical treatment. This is conducive to accurately, safely, and quickly resolving intestinal obstruction problems and improving the accuracy of diagnosis and treatment.
