[Device for abdominal drainage].

Abstract

A device for draining the abdominal cavity is suggested consisting of a system of 4-5 tubes with openings in the sides. The tubes of the system are joined to form a loosely coiled braid with a large coil pitch, while the axes of the side openings in the tubes are arranged on the helicoidal line with a pitch differing from that of the braid. This design of the device makes it possible to avoid obstruction of the side openings of the drain by the mobile organs and tissues of the abdominal cavity, which considerably raises the efficacy of draining in vacuum aspiration. The device is simple in design and may be easily constructed using 4-5 ordinary drainage tubes. The device was used successfully in 6 patients for abdominal drainage after resection of the liver for focal lesions.

Traditional Foley drainage systems--do they drain the bladder?

PURPOSE: Foley catheters are assumed to drain the bladder to completion. Drainage characteristics of Foley catheter systems are poorly understood. To investigate unrecognized retained urine with Foley catheter drainage systems, bladder volumes of hospitalized patients were measured with bladder scan ultrasound volumetrics. Additionally, an in vitro bench top mock bladder and urinary catheter system was developed to understand the etiology of such residual volumes. A novel drainage tube design that optimizes indwelling catheter drainage was also designed. MATERIALS AND METHODS: Bedside bladder ultrasound volumetric studies were performed on patients hospitalized in ward and intensive care unit. If residual urine was identified the drainage tubing was manipulated to facilitate drainage. An ex vivo bladder-urinary catheter model was designed to measure flow rates and pressures within the drainage tubing of a traditional and a novel drainage tube system. RESULTS: A total of 75 patients in the intensive care unit underwent bladder ultrasound volumetrics. Mean residual volume was 96 ml (range 4 to 290). In 75 patients on the hospital ward mean residual volume was 136 ml (range 22 to 647). In the experimental model we found that for every 1 cm in curl height, obstruction pressure increased by 1 cm H2O within the artificial bladder. In contrast, the novel spiral-shaped drainage tube demonstrated rapid (0.5 cc per second), continuous and complete (100%) reservoir drainage in all trials. CONCLUSIONS: Traditional Foley catheter drainage systems evacuate the bladder suboptimally. Outflow obstruction is caused by air-locks that develop within curled redundant drainage tubing segments. The novel drainage tubing design eliminates gravity dependent curls and associated air-locks, optimizes flow, and minimizes residual bladder urine.
