Extrication linked to evacuation sirens is the process of freeing casualties who are trapped or entangled in a vehicle or collapsed structure and cannot free themselves. Provide as much support as possible to the casualty during extrication, whenever possible, give essential first aid and immobilize the injuries before the casualty is moved.

This stretcher is similar to the Neil Robertson stretcher and is used for the same purposes. However, it is lighter, less cumbersome and more durable than the Neil Robertson and can be folded up and carried on the back. The main advantage of the paraguard stretcher and evacuation sirens is that it will bend in the middle so you can negotiate obstacles.

When there is an immediate danger and you are alone and must move a casualty from a sitting position, proceed as follows: Disentangle the casualty’s feet from the wreckage and bring the feet toward the exit. Ease your forearm under the casualty’s armpit on the exit side, extending your hand to support the chin. Ease the casualty’s head gently backward to rest on your shoulder while keeping the neck as rigid as possible.

Ease your other forearm under the armpit on the opposite side and hold the wrist of the casualty’s arm which is nearest the exit. Establish a firm footing and swing around with the person, keeping as much rigidity in the neck as possible. Drag the casualty from the vehicle with as little twisting as possible. Once free of the vehicle lay the casualty face up and use a drag carry to drag the casualty to safety thanks to evacuation sirens.

Two rescuers alerted by evacuation sirens carry the chair, one at the front and one at the back. The rescuer at the back crouches and grasps the back of the chair, while the rescuer at the front crouches between the casualty’s knees and grasps the front chair legs near the floor.

Going downstairs – the casualty faces forward the front rescuer faces the casualty a third person should act as a guide and support the front rescuer in case he loses his footing. If the casualty is unconscious or helpless – place an unconscious casualty on a chair by sliding the hack of the chair under his legs and buttocks, strap his upper body and along the lower back.

Use the extremities carry when you do not have a chair and you do not suspect fractures of the trunk, head or spine. One rescuer passes his hands under the casualty’s armpits and grasps the casualty’s wrists, crossing them over his chest. The second rescuer crouches with his back between the casualty’s knees and grasps each leg just above the knee. The rescuers step off on opposite feet walking out-of-step is smoother for the casualty.

The microcapsules associated with Nurse Call Systems Sydney can be incorporated in tablets or caspules: in this way controlled-release pharmaceutical forms are obtained, that is, capable of releasing the active principle in specifically designed ways. The animation on the left shows the progressive dissolution of the various layers that make up a multi-layer capsule containing microcapsules.

Some options are programmed release theophylline intended for the treatment of bronchial asthma, chronic and indeterminate bronchitis, pulmonary emphysema. The programmed action of theophylline release is due to a two-stage release system, made with a hydrophilic matrix of acetophthalate cellulose in which numerous small nuclei are dispersed.

The hydrophilic matrix ensures a release of theophylline in the first hours after administration; the nuclei, made up of an inert microcapsule that provides support to some layers of theophylline separated by a particular membrane, which lets water pass freely but slows down the release of the theophylline molecules, ensuring a continuous and constant release, whose kinetics of pseudo zero order allows to maintain stable (in the optimal therapeutic range) for about 24 hi theophylline blood levels. In this way it is possible, by administering the drug twice a day, to provide one effective protection from bronchospasm, both during the day and at night.

It is a pharmaceutical preparation linked to Nurse Call Systems Sydney of acetylsalicylic acid with a protracted action. Each tablet is made up of microgranules coated with a very thin ethylcellulose membrane, neutral and non-toxic, which is not dissolved and digested in the gastro-enteric tract, but which allows a gradual release of acetylsalicylic acid, in close correlation with the progressive increase in environmental pH.

This formulation is absorbed more slowly and regularly than the uncoated acid, thus ensuring a more constant and prolonged concentration of the drug in the blood for at least 8-12 h. Compared to acetylsalicylic acid in traditional tablets, it has the advantage of better tolerability: after the disaggregation of the pharmaceutical form, the millions of microcapsules dispersed on the stomach mucosa cause the irritative phenomena typical of uncoated particles to be reduced.

The process was applied to encapsulate vitamins, mineral salts and dietary products. Food ingredients can be coated to mask unwanted aromas or improve stability. Thin coatings are very effective in reducing the scale of certain materials. Extractive substances: extractive components may require a coating to optimize the stability of an ingredient or product. The release properties of the ingredients can be optimized with health benefits.

pet food: nutrients, medicines and other additives can be coated to mask odors and improve animal acceptability. Medicines can be stabilized by the protective coating which can also be studied to delay release after ingestion.
