An example catheter includes a tubular body portion and a cuff. The tubular body portion has a proximal end portion and a distal end portion. The distal end portion defines a distal face of the tubular body portion. The cuff is mounted to the distal end portion and defines a distal face of the cuff. In certain embodiments, the tubular body portion terminates within the cuff such that the distal face of the body portion is positioned proximally of the distal face of the cuff. In certain embodiments, a pocket is formed between the cuff and the body portion. In certain embodiments, the body portion is more rigid than the cuff.

The invention discloses an auxiliary suturing device for deep perineum laceration rectum packing, and relates to the technical field of medical instruments, the auxiliary suturing device comprises a hollow tube, an air bag is fixedly connected to the outer side wall of the hollow tube, a flow guide tube is fixedly connected to the bottom end of the hollow tube, and an anus patch is fixedly connected to the outer side wall of the flow guide tube; the device is fixed by tightly adhering the anus paste to the perianal skin of a puerpera, the air bag is slowly inflated through the inflation nozzle at the tail end of the inflation tube, the inflation amount is adjusted in combination with feedback of the puerpera in the inflation process, the one-way inflation valve on the inflation nozzle can lock air in the air bag, and positioning failure caused by pressure loss is prevented; the expanded air bag is attached to the rectum wall from the interior of the rectum, when medical workers conduct perineum laceration suture, the laceration bottom can be positioned by touching the edge of the air bag, the situation that a suture needle stabs the rectum wall by mistake is avoided, and if the suture needle makes contact with the air bag accidentally, air leakage of the air bag can be caused, and the medical workers can find operation deviation in time through touch or the shape change of the air bag.

The system includes a catheter and a pressure management device. The catheter includes a cuff, a resilient device, a drain passage, and a first fitting. The cuff defines a chamber and has a deflated state and an inflated state. The resilient device is disposed within the chamber and has a compressed state and an expanded state. The resilient device is configured to expand from the compressed state to the expanded state upon transition of the cuff from the deflated state to the inflated state. The drain passage extends from the cuff to an exhaust port. The first fitting is in fluid communication with the chamber. The pressure management device includes a second fitting that engages the first fitting and at least one check valve in fluid communication with the second fitting. In this embodiment, the at least one check valve includes an inlet check valve in fluid communication with the second fitting and an outlet check valve in fluid communication with the second fitting.

The invention discloses a multifunctional anal tube compression hemostasis cannula, and relates to the technical field of medical instruments, in particular to a multifunctional anal tube compression hemostasis cannula which comprises a breather pipe, an air bag is wrapped outside the breather pipe, and an air bag inflation head is arranged at the side end of the air bag. The breather pipe is made of hard plastic, the diameter is about 1 cm, the length is 7-8 cm, and the two ends of the breather pipe are hollow. The air bag is tightly attached to the outer side of the circumference of the breather pipe, can be inserted into the anus along with the breather pipe when not inflated, and expands and compresses to stop bleeding after being inflated. After the air bag is inflated, the middle is slightly thin, the diameter is about 3cm, the two ends are expanded, the diameter is about 4cm, and the whole air bag is dumbbell-shaped. The length of the inflation tube connected with the inflation head is 3-4 cm, the size of the inflation tube is 1.5-2 cm, inflation and deflation and pressure maintaining of the air bag can be controlled, and the compression force can be adjusted. The cannula can keep the anal tube to be exhausted, is easy to insert without being inflated, and can be used for hemostasis by compression, auxiliary anal dilatation and prevention of slippage after being inflated.

A system includes a catheter and a pressure management device. The catheter includes a cuff, a resilient device, an evacuation passage, and a first fitting. The cuff defines a chamber, and has a deflated state and an inflated state. The resilient device is positioned in the chamber, and has a compressed state and an expanded state. The resilient device is configured to expand from the compressed state to the expanded state to thereby cause the cuff to move from the deflated state to the inflated state. The evacuation passage extends from the cuff to an evacuation port. The first fitting is in fluid communication with the chamber. The pressure management device includes a second fitting engaged with the first fitting, and at least one check valve in fluid communication with the second fitting. In certain embodiments, the at least one check valve includes an inlet check valve in fluid communication with the second fitting, and an outlet check valve in fluid communication with the second fitting.
