Suction accumulator in rotary compressor is an important component from standpoints of compressor cost, performance, sound and ability of controlling excess liquid refrigerant. Because of its importance, it deserves its due attention to enhancement of its functions. This paper first defines functions of an accumulator, lists major design parameters and their common ranges. Then, a couple of maj...

OBJECTIVES This is a prospective study of the clinical efficacy of the V.A.C. Granufoam Bridge Dressing for the treatment of diabetic foot ulcers. MATERIALS AND METHODS Five consecutive patients with diabetic foot ulcers were treated with V.A.C. Granufoam Bridge Dressings and studied over a period of 22-48 days. The indications for treatment included diabetic patients with open ray amputation...

Background We report two unusual separate complications after uterine artery embolization for a late postpartum haemorrhage. This report appeared important to us in view of the apparent absence of any other publications on this topic. Case presentation We report the case of a 25-year-old woman, gravida 3, para 1, admitted for uterine bleeding 7 days after a spontaneous delivery at term, in ou...

Commonly encountered difficulties during decannulation are tube dependency, bleeding, and mechanical problems with cuff, aspiration, pulmonary complications, tracheomalacia, scarring of the tracheostomy wound, inversion of wound margin in skin, tracheal stenosis and also migration of granulation tissue inside the trachea through the tracheostomy wound. Patients with traumatic quadriplegia follo...

Suction valves with even thinner and narrower, used in a high efficient reciprocating compressor, are required in order to reduce suction resistances. However, low flow resistance suction valves run properly under the very severe operating condition of high periodic impact stress which can cause the compressor failure. In this study, the effects of the valve design parameters on the impact fati...

This paper reports results from an investigation into the suction caissons failure mechanisms under vertical pull-out loads. An insight to the failure mechanisms of suction caissons paves the path for developing analytical solutions to their pull-out capacity. The numerical models of suction caissons have first been calibrated by and verified against several experimental data from other researc...

Objective: The aim of this trial was to determine whether endometrial scratch-suction caused by insertion tube of (IUCD) with suction improved the probability of pregnancy in the subsequent IVF cycle in patients who had previous failed IVF outcome by removing small polyps and any hazardous materials. Design: Observational prospective cohort experimental study. Setting: Zagazig University Hospit...

BACKGROUND The established treatment for bacterial arthritis of the knee joint is arthroscopic surgery with irrigation and debridement. The aim of this article is to summarize the relevant data in treating bacterial arthritis of the knee joint, and based on these findings to present a novel irrigation suction system, tested in a cadaver study, as an additional tool in the postoperative treatmen...

BACKGROUND Total knee arthroplasty is associated with hematoma formation and extensive blood loss up to 1.5 liters. The placement of a closed suction drain to control this complication is controversial. The purpose of this study is to determine the efficacy between total knee arthroplasty without a drain and with a closed suction drain.  Methods: A retrospective cohort study was conducted betwe...

The purpose of this study was to determine the safety and cost-effectiveness of not routinely changing in-line suction catheters for patients requiring mechanical ventilation. Patients were randomly assigned to receive either no routine in-line suction catheter changes (n = 258) or in-line suction catheter changes every 24 h (n = 263). The main outcome measure was the incidence of ventilator-as...
