Description

TECHNICAL FIELD OF THE INVENTION [001] The present invention relates to a hood, typically a disposable hood, of the type used by an operator, particularly a surgeon, associated with a protective helmet. FUNDAMENTALS [002] As is known, current surgical procedures establish that the surgeon uses a protective helmet, usually instrumented, over which a hood, often disposable, is worn. The latter covers the helmet and then the individual's head, as well as the neck and part of the thorax. Over the hood, or rather, over the thoracic part of it, a surgical gown is then used, usually also of the disposable type. [003] The aforementioned surgical garment aims to guarantee complete external sterility for the surgeon, and this becomes quite complex due to its nature, especially regarding the methods of donning it. In fact, the hood is supplied folded in sterile conditions and includes a lens to be positioned in a dedicated opening. When unrolling the rear portion of the hood, bringing it to cover the nape of the neck and shoulders of the individual, there is a risk that the outer part of the hood itself may be touched, by the surgeon or the assisting professional, in non-sterile conditions. For example, this portion may come into contact with the surgeon's arms or other parts of the body not protected by sterile gloves. This, in fact, invalidates the surgeon's garment in a way that is often not noticed and, therefore, not remedied. [004] Furthermore, when the surgeon dresses alone, putting on the hood becomes extremely uncomfortable, especially in the phase that requires inverting a portion of it to cover the nape of the neck and back. This procedure involves unnatural arm movements that actually cause discomfort to the surgeon himself in a phase prior to the operation, when he must remain rested and focused. [005] The same drawbacks occur even in relation to other applications of the hood of the type mentioned above, not necessarily medical applications, and other operators, not necessarily health professionals, for example, in the so-called “clean rooms” of research and experimental laboratories. SUMMARY OF THE INVENTION [006] The technical problem posed and solved by the present invention is, therefore, primarily to provide a protective hood that allows solving the inconveniences mentioned above with reference to the known art. [007] This problem is solved by a hood according to claim 1. [008] The preferred features of the present invention are presented by the dependent claims. [009] In the context of the present description, the terms "sagittal", "frontal", "anterior", "lateral", "posterior", "superior", "inferior" and derivatives are assigned to the elements of the hood or their positions and refer to the worn configuration of the hood itself, even in association with the anatomical definitions of the operator's body wearing it. [010] In general terms, the hood of the invention is of the type suitable for covering completely, or almost completely, the head, neck and upper chest of the operator. [011] The hood of the invention is equipped with a pair of cords (or “chest straps”), fixed to the back of the hood that covers the head, neck and upper chest. These cords can be held by the surgeon with sterile gloves and allow him to use the hood autonomously and easily, pulling it into position without the risk of contaminating the outer portion of the same. [012] The aforementioned cords are configured in such a way as to allow – during donning – a sufficient distance to be maintained between the individual’s arms and the main body of the hood in order to prevent interference between the arms and the outer part of the hood itself. Therefore, the risk of contamination between the outer part of the hood, which is sterile, and the individual’s body, which is not sterile, is drastically reduced. [013] Advantageously, the same two cords can be tied, or even connected to each other, at the user's chest at the end of the donning procedure. In this way, they hold the front, back and side portions of the main body of the hood in position, particularly during the subsequent donning phase of the apron. [014] Therefore, when the surgeon, or generally the operator, is fully gowned and ready for the work he/she must perform, the cords remain inside the garment, which is under the apron. [015] In other words, the cords are designed and positioned as an aid to a contamination-free placement procedure. [016] Other advantages, features and embodiments of the present invention will become apparent from the following detailed description of its embodiments, shown by way of example and not for limiting purposes.
