The control of infection of patients in hospitals, clinics, and doctors' surgeries has become an ever more pressing concern with the rise of infectious bacteria resistant to multiple antibiotics, in particular methicillin-resistant staphylococcus aureus (MSRA). In the United Kingdom alone there are thought to be about 5,000 deaths a year from infections caught in hospitals but some experts believe the number could be as high as 20,000.
Research has shown that high levels of MRSA are present on everyday items in hospitals. Samples taken from an intensive care unit at a London hospital found MRSA on charts, bins, pens, medical notes, phones and computer keyboards. There was also MRSA present on staff aprons and hands. The most common route for MRSA infection is between patients or via a doctor or nurse. Hospital staff can spread MRSA by using such items after having contact with patients.
Research has also shown that if someone has MRSA on their hands, the bacteria would be left on the next four surfaces touched by that person. Once MRSA is on an item it will remain there for up to 80 days unless that item is cleaned.
Disposable medical gloves can help prevent cross-contamination, but a problem arises if external parts of the glove are touched by a person prior to or during donning of the glove. Such external parts can then become contaminated prior to use U.S. Pat. No. 4,844,293 discloses a glove dispensing system where a package of gloves is placed in an outer container, and gloves are dispensed through registering apertures in the package and the outer container. The cuffs of the gloves are not directly accessible to the user.
This arrangement encourages users to touch a glove only by the cuff and so minimise the risk of contamination, but at the cost of increased mechanical complexity and the need to apply an adhesive to the otherwise pristine external surface of the glove.
Most gloves used in hospitals and clinics are examination gloves, and these are used in large numbers such gloves are supplied not in individual sterile packages, but in relatively inexpensive cardboard dispensing boxes. One way of controlling contamination on such examination gloves is disclosed in patent document U.S. Pat. No. 5,816,440. In this disclosure, gloves are packaged with over-folded cuffs within a box having a dispensing aperture. The fingers of each glove are looped partially or interfolded around the cuff of the subsequent glove so that as each glove is pulled from the aperture, the cuff of the next glove is pulled out of the aperture to make it easy for a user to get hold of the over-folded cuff of the next glove.
Apart from the several additional manufacturing steps entailed by this arrangement, the combination of cuff over-folding and interfolding of neighbouring gloves creates voids within the stack of interfolded gloves and so reduces the number of gloves which can be packed in a given volume. Furthermore, the cuff of the next glove may not always be reliably pulled from the aperture.
Another glove dispensing system is disclosed in U.S. Pat. No. 5,921,434, in which gloves are packed flat in the same orientation one on top of another within a box having a dispensing aperture. The cuffs of the gloves are held in place by an elastic band, which passes through a hollow roller that presses on the inside surface of a part of the cuff of the next glove to be dispensed. Neighbouring gloves are partially adhered to each other so that as each glove is pulled from the box the cuff of the next glove is pulled partially out of the box by the action of the roller and adhesive between the gloves.
This arrangement encourages users to touch a glove only by the cuff and so minimise the risk of contamination, but at the cost of increased mechanical complexity and the need to apply an adhesive to the otherwise pristine external surface of the glove.
It is an object of the present invention to provide a more convenient and reliable arrangement for dispensing gloves in a medical or clinical environment or in any other environment where the control of hand borne contamination is important.
According to a first embodiment of the invention, there is provided a dispenser for disposable gloves, comprising a container and a plurality of disposable gloves, wherein:
The term “finger portion” here means the portion of the gloves for covering the four fingers of a user's hand, and optionally also the portion of the glove for covering the user's thumb.
The folded arrangement of the gloves according to the invention provides a number of benefits. First the finger portion of the glove when stacked flat will tend to have a degree of wasted space between the fingers, as compared with the cuff portion which, of course, is of one piece and so presents no such wasted space. The result is that the packed volume of a particular number of stacked gloves, when folded with the finger portion bearing against the cuff portion, is less than the packed volume of the same number of gloves when stacked in a non-folded arrangement. Here, the packed volume is the volume of an equivalent multi-sided dispensing container, which will most practically be a six sided box.
In a preferred embodiment of the invention, the container is a six-sided, approximately cubic box, and the aperture extends around a right angled edge of the box across two adjacent sides, one of which is substantially bisected by the aperture, and the other of which the aperture extends only proximate said edge.
Furthermore, because gloves are invariably longer from cuff to fingertip than they are broad, the folded arrangement according to the invention can be formed into a stack with approximately cubic proportions. This tends to minimise the volume of the stacked arrangement as compared with the surface area of the container, thus reducing the relative amount and cost of packaging necessary to form the container used for the glove dispenser. An approximately cubic packing arrangement also provides greater flexibility in terms of where the dispenser can be mounted, placed or used, owing to the reduced maximum dimensions of the container.
In a preferred embodiment of the invention, the gloves are stacked one on another between opposite ends of the stack, and the glove dispenser is arranged in use to dispense gloves preferentially from a first one of these ends. The finger portion of each glove is then folded back against a side of the cuff portion furthest away from said first end of the stack of gloves. Thus, the finger portions are covered over prior to being dispensed, so that any contamination from the user upon touching the glove will be limited to the cuff portion or region of the glove.
Preferably, in order to facilitate access to the next glove to be dispensed, the dispensing aperture includes a portion of the aperture that extends across a portion of a face of the container opposite the top side of the stack.
When vertically oriented in use, the stack will have a top side and a bottom side. The aperture may therefore be shaped to facilitate preferentially the removal of gloves cuff first from the top side of the stack, the finger portion of each glove therefore being folded underneath the cuff portion of the same glove.
In a preferred embodiment of the invention, the dispenser comprises additionally a movable plate within the container, the plate being positioned on the top side of the stack of gloves to protect the topmost glove in the stack. The movable plate preferably moves downwards under its own weight as each glove is dispensed from the top of the stack of gloves. Therefore, there are preferably no means biasing the movable plate towards the stack of gloves, which simplifies the manufacture and operation of the dispenser as compared with a dispenser having such means.
The dispensing aperture may include a portion of the aperture that extends across a portion of a face of the container opposite the top side of the stack. The movable plate may then be shaped to conform to the shape or extent of this portion of the dispensing aperture. This helps to maximise the accessibility of the next glove to be dispensed while at the same time providing protection over the stack of gloves outside the bounds of the dispensing aperture.
Also according to a second embodiment of the invention, there is provided a dispenser for disposable gloves, comprising a container and a plurality of disposable gloves, wherein:
The invention further provides a system for dispensing disposable gloves, comprising a wall-mountable holder and a dispenser for disposable gloves, the dispenser being as described above according to either the first or the second embodiments of the invention, wherein the dispenser may be securely and removeably held in the holder so that gloves can be dispensed from the dispenser when held in the holder.
The invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
The removable portion is subdivided horizontally into three sections 14, 15, 16 by means of a pair of parallel cuts 18, 19 that extend horizontally between opposite vertical sections of the perforated line 12 in the container front face 3. The cuts need not be full cuts through the container material, but may be partial cuts or perforations which are weaker than the peripheral perforation 12.
This is done so that the three sections 14, 15, 16 of the removable portion 6 can be removed one at a time. The container is opened first by removing the topmost section 14, which extends across an upper central portion of the front face and includes a central portion of the top edge and all of the semicircular area 11 on the top face 5. As will be explained below, gloves may then be removed through an aperture thus formed, and as the level of gloves inside the container 2 drops, the middle and bottom sections 15, 16 may be removed to enlarge the aperture.
Reference is now made also to
In order to produce a more evenly stacked arrangement, and minimise high spots in the stack, it is preferable if the glove thumb 35 is folded inwards between other adjacent or nearby fingers and a palm section 37 of the glove, with the long axis of the thumb 35 being angled inwards but directed mainly forwards. Optionally, the thumb little finger 34D may also be folded inwards between other adjacent or nearby fingers and the palm section 37 of the glove, with the long axis of the little finger 34D being angled inwards but directed mainly forwards in a similar fashion to the thumb.
The glove folding arrangement shown in
The upper cuff portion of each glove 22 therefore protects the lower finger portion 24 from collecting external contamination, particularly during the process of removing a glove from the container. To this end, in this embodiment, it is important that the glove finger tips 38 do not reach as far as the actual cuff opening 40, so that the glove finger tips are not inadvertently touched by a user pulling a glove 22 out from the container 2. Therefore, the finger portion 34 may preferably rest beneath the section 37 of the glove cuff portion 36 which, in use, covers a user's palm.
The protective movable plate 26 sits loosely on the topmost glove 22′, and follows the stack 20 down under its own weight as gloves 22 are removed, usually one at a time, from the container 2. The plate 26 has a semicircular cut-out 44 which matches the shape of the semicircular area 11 of the aperture 24 in the container top face 5. The semicircular cut-out 44 and area 11 are aligned so that a user can reach into the container from above and through these semicircular features to grip the cuff 38 of the topmost glove 22′. The movable plate 26 therefore prevents a user from touching parts of the glove topmost 22′ not revealed by the cut-out 44 and therefore helps prevent contamination from reaching other parts of the glove.
The folded aspect of the gloves 22 also helps the gloves to be pulled from the stack 20 one at a time without dislodging adjacent gloves, particularly the glove beneath the glove being pulled out from the container 2. This is because each part of the glove finger portion 34 of the glove being pulled out tends to remain in place until it is rotated upwards and out towards the dispensing aperture 24. This substantially eliminates rubbing against the glove below the one being dispensed, and so helps to preserve the position of the glove below. Although the top plate 26 may experience some rubbing and consequent friction, the plate is retained within the volume 28 of the container 2 by means of contact between portions 50 of the plate adjacent the semicircular cut-out 44 and an opposing inside surface 52 of the container 2.

The invention therefore provides a number of benefits and advantages. During use the finger portion of the glove 222, 122, 222 next to be dispensed is covered by the cuff portion of the same glove, which helps keep clean gloves not yet dispensed. The aperture 24 is shaped to facilitate preferentially the removal of gloves cuff first from the top side of the stack 20, the finger portion of each glove being folded underneath the cuff portion of the same glove. This helps to reduce the potential for contamination of the cuffs of gloves not yet dispensed from the container 2.
The various folding arrangements described above result in a rectangular or substantially square outline of the glove stack, as viewed in a horizontal plane. The initial height of the stack is preferably about the same as the short side of the rectangular outline or each side of the square outline. Preferably the container can have an approximately cubic shape or at least a square cross-section in one plane, thus reducing the cost and quantity of packaging needed to form the container.
The dispensing aperture preferably does not extend the complete width of that face of the box. The parts of the dispensing face retained on either side of the aperture act as retainers for the gloves remaining in the stack to prevent them being removed or dislodged as remaining gloves are dispensed. This arrangement also protects a greater portion of the glove from the external environment prior to dispensing.
The overall arrangement therefore also helps to minimise or eliminate touching of the container surfaces surrounding the gloves when a user reaches to pull out one or more gloves from the dispenser. A user can pull out a glove by the cuff without contaminating the main surface portion of the glove, either by touching the glove directly or by dragging the glove across previously contaminated aperture surfaces.
The features described above therefore help to keep the most important external surfaces of the glove used by medical, dental, veterinary or food workers free from pathological micro-organisms.
The invention therefore provides a convenient and reliable arrangement for dispensing gloves in a medical or clinical environment, or in any other environment where the control of hand borne contamination is important.
