In the medical literature, there is a consensus that there are not any effective treatments for capillary leak syndrome. (Eric Siddall - Capillary leak syndrome - 2017)
In the last decades, many clinical trials have tested immunomodulatory compounds designed to restore homeostasis in patients with sepsis. Despite these efforts, which cost hundreds of millions of dollars, not a single new drug has been integrated into clinical practice. Thus, it is obvious that the clinical and scientific communities need to reconsider the therapeutic approach to sepsis. New strategies to treat sepsis face serious challenges along their way to patient’s treatment in the Intensive Care Unit (Tom van der Poll - Future of sepsis therapies 2016).
The invention consists of a dry immersion bed for treating patients, which comprises: a membrane, a water tank with a floor and four walls and a bed. The four walls and the floor of the water tank form an open top water-tight container. The membrane is arranged between the patient and the external surface of the bed, separating the patient from the water below him.
The bed is capable of displaying, at least, the following degrees of freedom in relation to the water tank floor: up and down in relation to the floor; tilted forward and tilted backwards in relation to the front and rear wall; right rotation and left rotation towards the side walls; chair position and lying position.
The bed is connected to the tank’s floor using at least one vertical actuator; and is segmented into four platforms, which are: first platform; second platform; third platform; and the fourth platform; the first platform being adapted to support the patient's head and back; the second platform being adapted to support the patient's seat (buttocks); the third platform being adapted to support the patient's thighs; and the fourth platform being adapted to support the patient's legs and feet.
The platforms are (preferably) perforated and have degrees of freedom between themselves and are equipped with angular actuators, capable of providing a change in the angle defined between the different platform portions (meaning: the angle defined between the first and second platforms; the angle defined between second and third platforms; and the angle defined between the third and fourth platforms).
The vertical actuators together with the angular actuators, being able to provide the following treatment positions: fowler position; semi-fowler position; trendelenburg position; anti-trendelenburg or reverse trendelenburg position; cardiac position; anti-shock position; and inclination with head position above the feet.
For the purpose of treatment for several days in ICUs, in which the patient alternates moments out of the water with moments of immersion, it is necessary to use a mattress, preferably inflatable, to comfortably accommodate the patient. In addition, it is important that the mattress is perforated, to allow water to circulate, and made of salty water resistant material (e.g. elastomer, or polychloroprene), as it may be necessary to add salt (NaCl) to increase the density of water in periods of immersion. Additionally, it is important that the water temperature is set as close to normal body temperature (36.5°C), as ICUs are normally very cold. In addition, hyperthermia and/or hypothermia are a common occurrence, enforcing the need for water temperature control.
In order to provide the bed structure with greater safety against shocks, internal pressure and for better fixation of the transparent walls, the edges and floor of the tank are made of stainless steel, austenitic or duplex type. The combination of these characteristics allows for safe use of the equipment also assuring it is adapted to ICU conditions for several days.
