Description

Ventilated surgical gown
Technical field The present invention relates to a ventilated surgical gown.
Background art
During operations, surgeons and nurses must wear sterile surgical gowns in order to achieve a sterile barrier that prevents bacteria from the theatre staffs clothes and skin from reaching the site of the operation. In order to achieve this sterile barrier, it is necessary for the gowns to be made of non- permeable material, which is not optimal as far as comfort is concerned. In particular, during long operations lasting 2-12 hours, heat and sweat can cause severe problems that have an adverse effect on a surgeon's performance.
Devices for increasing the comfort of theatre staff wearing surgical gowns by extracting the air between the surgical gown and their clothes are known through GB 2 107 971 and EP 0 171 671 Bl. GB 2 105 971 describes a device that resembles a neckband, that hangs down over the chest and back and is connected to an air extractor. The air is extracted through a number of holes on the part of the device that extends down the user's chest. EP 0 171 671 Bl shows a waistcoat-like device with a number of ribs that extend between the waistcoat and the user's body to keep the waistcoat at a distance from the user's body. In addition, this device has one or more hoses that are located between the waistcoat and the user's body and are connected to a suction device.
The known devices are made of relatively stiff material in order to be able to withstand the negative pressures that are generated without being damaged, and are therefore relatively awkward to wear. In addition, they are relatively noisy, which can be distracting for the theatre staff. The connection to the air extraction system in the operating theatre also means that the staff who are wearing these devices cannot move around freely in the operating theatre and that the connections can get in the way of other theatre staff who are moving around in the operating theatre. There is therefore a need for a ventilation system for theatre staff that is more comfortable to wear and that does not restrict the movements of the theatre staff.
The object of the present invention is to fulfil this need.
Disclosure of invention
This object is achieved by a ventilation system for a surgical gown, characterized in that the gown is provided on the inside with a plurality of air outlets and comprises airways for taking air to the air outlets, which airways are arranged to be able to be connected to a compressed air source. As the system utilizes positive pressure instead of negative pressure to generate air currents, it is not necessary for the airways to have a certain rigidity, but instead soft materials can be used, which makes it more comfortable for the user. In addition, the airways are at least mostly integrated into the surgical gown, which makes it easier to put the system on a user and to store and handle the system before use. In addition, the integrated airways can be made of cheap material, which makes it possible to use disposable surgical gowns.
In a first preferred embodiment, the airways consist of ducts constructed in the surgical gown, which open out at the inlet end into a manifold that can be connected to the compressed air source, and of air outlets consisting of openings in the duct walls and/or the open ends of the ducts. The ducts can be constructed of elongated strips of flexible material, the long edges of which are attached to the inside of the surgical gown. Alternatively, an inner layer can be attached to the inside of the surgical gown in lines or at individual points, with the spaces between the adjacent attachment points or lines forming ducts for the air flows, in addition to which the inner layer has openings that form air outlets, for which reason the inner layer can be perforated or can be made of a material that is more permeable to air than the material of which the surgical gown is made.
In addition, the compressed air source consists of a portable apparatus, for example a portable fan or pump, that comprises fixing devices for attaching it to the surgical gown or to the wearer of the surgical gown.
Brief description of drawings
The invention will now be described with reference to the attached drawings, in which:
Figure 1 shows schematically a plan view from in front of a surgical gown provided with a ventilation system according to a first embodiment of the invention,
Figure 2 shows the surgical gown according to Figure 1 in a plan view from the back and with the back of the gown removed, and
Figure 3 shows a similar view to Figure 2 of a surgical gown provided with a ventilation system according to a second embodiment of the invention.
Mode(s) for carrying out the invention
The surgical gown 1 shown schematically in Figures 1 and 2 is provided with a ventilation system according to a first embodiment of the invention. The gown 1 is of conventional construction and can, for example, consist of - A -
a disposable surgical gown available under the brand name Klinidrape® from Molnlycke Health Care AB, Gothenburg, Sweden.
The ventilation system comprises a compressed air source and a plurality of ducts, which ducts are integrated into the surgical gown. In Figures 1 and 2, only the ducts 2-8 are illustrated that run along the front part of the gown, but the gown 1 can also be provided with similar ducts at the back. In a first variant, the ducts are formed from elongated pieces of material, the long edges of which are attached to the inside of the surgical gown 1. In this variant, the parts of the inside of the gown 1 that lie in the area between the long edges of the pieces of material form part of the ducts that are created. In a second variant, the pieces of material can be tubular and can be attached to the inside of the gown 1. The attachment of the pieces of material can be carried out in any suitable way, for example, they can be sewn on, fused on or glued on.
The pieces of material can be made of plastic material, fabric, non-woven material, or combinations or laminates of these materials.
The compressed air source consists of a portable battery-operated fan 9. The fan 9 can be of the type that is used to blow air into facemasks. The fan 9 is attached to the surgical gown 1 in such a way that it is removable, for example by the use of hook and loop fastenings or a suitable adhesive. In addition, the outlet of the fan is attached in a suitable way to the supply duct 8, in such a way that it can be removed. The duct 8 opens out into a manifold 7, to which the open inlet ends of the ducts 2-6 are connected. Even though this is not shown in the Figures 1 and 2, the manifold 7 can also run along the back of the gown 1 and there can also be ducts on the back that are similar to the ducts 2-6 and that are connected to the manifold. The ducts 2-6 and any corresponding ducts (not shown) that are integrated into the back of the surgical gown 1 have outlets for enabling there to be a flow of air in the space between the inside of the gown and the body of the wearer of the gown. The outlets can consist of holes 10 that are arranged in the side of the ducts facing towards the user's body, holes 11 arranged in the ducts but directed to the side or to the sides, open outlet ends of the ducts or combinations of these. For example, the ducts 2 and 6 can have holes 11 that face sideways, for blowing air towards the user's armpits.
To use the ventilation system that has been described above, compressed air is supplied to the ducts 2-6 from the fan 9 and is blown out via the outlets 10, 11 over the user's body or clothes. The inlet of the fan 9 can be connected to the atmosphere in a suitable way, for example by an opening in the upper part of the gown, preferably at the back of the gown, or can simply be arranged to extract air from the lower part of the gown. As a result of the blowing out of air from the fan 9, a small positive pressure is created in the area between the gown and the user at the upper part of the gown. The gown is provided with air outlets, preferably at the back, that can be provided with filters or some other type of particle trap. In certain applications, it can be expedient to ensure that the neck of the gown fits tightly around the user's neck in order to ensure that no non-sterile air escapes at the neck.
Figure 3 shows a second embodiment of a ventilation system according to the invention integrated with a gown 12. A fan 13 is arranged on the inside of the gown in the same way as in the system according to Figures 1 and 2. The outlet of the fan 13 is connected via a supply duct 14 to the space between a piece of material 15 and the inside of the gown. The piece of material 15 is attached, for example sewn, fused or glued, to the inside of the gown in a suitable way, along its edges and in a pattern of attachment points 16. In addition, the piece of material 15 comprises air outlets (not shown) in at least some of the areas between the attachment points 16.
When the fan 13 is activated, air is forced through the duct 14 and into the space between the piece of material 15 and the inside of the gown 12. The spaces between the attachment points 16 form a pattern of ducts through which the supplied air flows and is then blown out through the air outlets arranged in the piece of material. In other respects, this system works in the same way as the system shown in Figures 1 and 2.
The gown 12 can also have a piece of material at the back, similar to the piece of material 15, which is connected to the fan 13 via a branch duct (not shown) from the duct 14 or from the space between the piece of material 15 and the inside of the gown 12.
The piece of material 15 can be made of the same material that is used for the ducts 2-8 in the embodiment according to Figures 1 and 2.
It is not necessary for the material in the ducts 2-8 or the piece of material 15 to be non-permeable, but instead it can be permeable, that is air can pass through it without it being necessary to make any holes in the material. When using air-permeable material, it is also possible to obtain the required flow of air by means of holes in the duct walls and/or by the dimensioning of the open outlet ends.
The embodiments that have been described can be combined, for example by letting the ducts extend from the space between the piece of material 15 and the inside of the gown 12 into the arm holes of the gown 12 or by replacing the ducts 3-5 with a piece of material similar to the piece 15 in Figure 3 that is connected to the branching duct 7 via a branching duct. Both these applications can be suitable for ensuring that there is an air flow to the area of a user where moist air forms first. It is, of course, also possible to arrange ducts in other locations than those shown in the embodiments. However, it has been found that the production of heat is greatest at the upper part of the upper body, for which reason it is expedient to concentrate the ventilation in this area.
The embodiments that have been described above can, of course, be modified within the framework of the invention. For example, the fan can be attached to the user in such a way that it is removable, for example by hook and loop fastenings or other mechanical fixing devices, instead of only being attached to the surgical gown in such a way that it can be removed. In order to make it easier to achieve a sterile attachment to a fan that can be attached to the user, this should be able to be attached to the user by manipulating it from the outside of the gown after the gown has been put on. For this purpose, a hook and loop fastening is a suitable solution, in particular if the element worn by the user (preferably the female element) is made sufficiently large so that no great precision is required for the attachment. If the fan is attached to the user, this must not be attached to the surgical gown in such a way that it can be removed, but can hang freely on the inside of the gown where it is connected to the supply duct. In addition, the ducts and the piece of material can have other shapes and extents than those shown in the embodiments, for example the ducts can extend into the sleeves of the surgical gown. It is also possible to use other types of compressed air sources than those described in the embodiments, for example fan apparatuses of a type different to those described or consisting of a pump that can be of the type that is used for automatic inflation of cuffs for continuous monitoring of a patient's blood pressure. Such a pump can easily be adapted to produce a constant supply of compressed air. The ducts in the piece of material 15 in the second embodiment can be created by means of a pattern of attachment lines instead of attachment points 16. The invention can also be used with gowns that can be used more than once. The invention is therefore restricted only by the content of the attached claims.
