A collection of devices and supplies used for the administration of a limited bath performed by immersing only the hips, buttocks, and the perineal region of the patient into water or a water solution (i.e., a sitz bath). It typically consists of a basin (e.g., a rigid plastic basin), an irrigation set with a bag, tubing, clamps and towels; some kits may include substances to add to the water (e.g., salts or herbs). This device is used with a sitz bath to maintain patient hygiene and for external hydrotherapy to alleviate pain and discomfort caused by haemorrhoids, uterine cramps, labour, and/or other diseases of the pelvic, abdominal and perineal area. This is a reusable device.
