An apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve providing selectable communication between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve is adapted for remote actuation and has a housing adapted to resist patient discomfort from leg-valve contact. Plumbing structure desirably maintains fluid supply and drain conduits in a substantially parallel arrangement to assist routing those conduits between a patient's legs. When the urine valve is oriented to permit communication with the fluid source, an infusion pump may be used to infuse a known quantity of fluid through the urine valve and into the patient's bladder. A pressure transducer desirably is connected in-circuit to indicate the fluid's pressure. To facilitate the infusion process, an automatic flow control device may be included in a fluid supply path and arranged to permit repetitive operation of a syringe to inject a bolus of fluid into the patient's bladder. Subsequent to a period of time in which to make a pressure measurement, preferred embodiments of the urine valve automatically return to a bladder draining position.

An anal inserting cleaning feces bag relates to a medical plastic equipment supply which adopts the physical or mechanical operation to remove feces for patients or caregivers and exempt from the harm caused by the increase of the intra-abdominal pressure which is caused by the initiative defecation of the patients or the caregivers by plugging into the anal. The whole structure is formed by connecting a casing, ancillary components and a soft transparent plastic bag. The casing is inserted into the the anal. In order to avoid the injury of the anal mucosa caused by the inserting of the casing, a casing core with the shape of a bullet on the top is inserted into the anal together with the casing. Once the casing is inserted into the anal, the casing core loses the function and is thrown into a plastic bag. The front end of the outer wall of the casing is provided with a ring sponge body sealed by a rubber film and an air duct controlling the incoming and the outgoing of air, so the tightening and the cracking off of the casing inserting into the anal are determined. After the casing is inserted into the anal, the thin feces can be discharged into the connected plastic bags by the casing directly under the peristalsis of intestines, a cleaning spoon arranged in one side of the plastic bag can be used to clean the feces which can not be discharged by the peristalsis of the intestines, or enema is inserted or medicinal oil is filled from an open hole of the other side for infiltration to help cleaning the feces.

A method for alleviating female urinary incontinence especially during episodes of increased intra-abdominal pressure is disclosed. The method includes the steps of providing a non-absorbent urinary incontinence device having an initial cross-sectional area, an insertion end and a trailing end. The urinary incontinence device also contains a compressed resilient member which is capable of increasing the cross-section area of the urinary incontinence device when expanded. The urinary incontinence device is inserted into a woman's vagina with the insertion end entering first. The vagina is a canal with an inner periphery made up of right and left lateral walls, an anterior wall and a posterior wall. The urinary incontinence device is inserted such that it contacts at least two of the walls. The urinary incontinence device is positioned in the middle third of the length of the vaginal canal with the insertion end aligned adjacent to a woman's urethral sphincter muscle. The urethral sphincter muscle is a part of the urethral tube. The urinary incontinence device cooperates with a woman's symphysis pubis to sandwich the urethral tube therebetween. The resilient member is allowed to expand within the vaginal canal such that at least a portion of the urinary incontinence device increases in cross-sectional area and contacts all four interior walls of the vaginal canal and provides a supportive backdrop for the urethral tube. The urethral tube is then permitted to be compressed upon itself between the urinary incontinence device and the symphysis pubis thereby limiting involuntary urine flow.
