The glove sleeve includes externally clip-on contacts and the cuff sleeve includes bayonet type helical ramps ( 30 ). The clip-on contacts of the glove sleeve slip in the helical ramps of the cuff sleeves until the glove sleeve is latched forming, once assembled, a sealed whole called a wrist ring ( 10 ).

Description:
[0001]    The present invention relates to the interchangeability of handling gloves with or without flange, under continuous sealing containment in the following industrial fields: pharmacy, animals, chemicals, etc. More precisely, the invention relates to a bidirectional device for changing a handling glove from inside to outside a glove box or from outside to inside the glove box also called: a containment envelope or insulator. 
         [0002]    Said device is intended to replace a used glove with a new glove, including a cuff sealingly connected to a cuff sleeve and a glove of a flexible material sealingly connected to a glove sleeve. The assembly thus formed is called a wrist ring. 
         [0003]    The invention also relates to a method for replacing a used glove with a new glove by means of the device according to the present invention.
       The handling of toxic products, very volatile chemicals is commonly performed in confined media. Confined media are also used to protect the elements from outside pollution, when a handling in sterile medium is intended, for example in the case of the pharmaceutical industry for packaging injectable drugs, breeding laboratory animals under aseptic conditions, anticancer drugs handled in hospital pharmacies, agro-food industry, etc.       
 
         [0005]    These confined media include a sealed envelope. To be able to make handlings from outside the envelope, this has apertures to which gloves are attached. Thus, a person introducing his/her hand in a glove, can handle objects contained in the envelope without any risk to pollute them and without risk of being contaminated. 
         [0006]    These gloves are mounted to the envelope in several ways, for example through collars integral with the envelope, called shoulder rings for gloves attached by an envelope collar or ring for gloves mounted on an interchangeable supporting collar by an ejection mechanism, called an ejection gun, replacing the collar of the used glove by a collar of a new glove by pushing. 
         [0007]    The shoulder rings are used both for depressurised cells and pressurised cells. The shoulder rings span the hand, the arm of the operator up to the shoulder. 
         [0008]    The ejectable systems on collar are only used to date for depressurised cells because the ejection mechanism is large in volume and weight and it cannot be used from inside the containment. 
         [0009]    In particular in the animal and pharmaceutical fields in sterile containment, the glove in a single length is split into two elements, that is a top part, being more resistant, called a cuff. This is connected at the envelope to a shoulder ring that can be circular or oval and with a significant size to offer more clearance to the operator. On the other hand, the glove is split into a bottom part which is connected to a sleeve at the wrist and enables a glove suitable for each handling to be mounted. This glove can be changed with a new glove from inside the envelope using the other hand. However, the changing method is very cumbersome. This method is conceivable at a research laboratory but certainly not in an industrial environment and hospital pharmacies. 
         [0010]    From document FR 2 913 362, a method for changing a glove mounted beforehand on a glove collar accommodated in the cuff collar attached to its end is known. 
         [0011]    The interchangeability of the used glove is achieved by conveying inside the envelope of a new sterile glove. This glove is mounted in a tooling called a “support”. From inside the cuff, a second tooling called a “pusher” is fed. The glove is engaged to the cuff collar and from the internal side of the insulator, the support containing the new glove fixed to its collar is brought to engage it to the collar of the used glove. The slipping of the cuff collar from the used glove collar up to the new glove collar is operated by pushing the pusher responsive to the support. 
         [0012]    This method requires dexterity from the operator and remains complex. 
         [0013]    The specific toolings, being the pusher and the support, enable for one the used glove and for the other the new glove to be received in cavities without pinching risk, hence the fact that toolings have non-negligible overall space in cell, in particular for the pusher. 
         [0014]    The principle retained for the glove collars to afford interchangeability are of two stages. This collar consists of a first sleeve the lower diameter of which is accommodated inside the cuff collar and a second sleeve having a diameter lower than the diameter of the first sleeve enabling the glove to be mounted and attached by a collar having two diametrically opposed heads. The diameter of the heads should be lower than the inner diameter of the first sleeve in order to make it possible for the one to penetrate the other which is necessary to the interchangeability principle retained. 
         [0015]    The major drawbacks of this principle are a decrease in the dexterity of the operator because of the thickening of the glove collar consisting of two sleeves and the increase in its length generated by their superimposition. The consequence of this state is to increase the weight and overall space of the glove at the wrist of the operator, which decreases by the same amount his/her dexterity and increases by the same amount his/her tiredness. 
         [0016]    The axial stopping of the glove collar in the cuff collar is achieved using hard spots. In the case of the previously described sealing means, the interchangeability strain becomes continuous and thus makes the operator losing the feeling of passing the hard spots of the locking means being indicative of the end of attachment. Then, the operator is not ensured to have ended the transfer of the glove to the sleeve collar. He/she is at risk of taking out the pusher with the used glove before placing the new glove on the collar. 
         [0017]    The secondary drawbacks of this principle are the following ones:
       the placement of the first glove requires a mask or an appropriate tooling;   the frustro-conical shaped lid requires the increase in the piston stroke of the support by a value equal to the height of the lid, which results in increasing the overall space and weight of the toolings;   the orientation of the glove can be erroneous. Indeed, the glove can be placed a thumb upwards, which is the proper position or thumb downwards which is an improper position. There is no foolproofer enabling the proper upwardly thumb position to be surely ensured.       
 
         [0021]    Consequently, the present invention has the purpose to provide a device for changing a glove on a sleeve overcoming the abovementioned drawbacks and offering a great safety and ease of operation for operators concerning containment. 
       DISCLOSURE OF THE INVENTION 
       [0022]    A first object of the invention is a device for changing a handling glove from inside to outside a glove box and from outside to inside under confinement, said device being intended to replace a used glove with a new glove, including a sleeve sealingly connected to a shoulder ring sealingly mounted to the wall of a containment envelope sealingly connected to a cuff sleeve, and a glove of a flexible material sealingly connected to a glove sleeve. 
         [0023]    According to the invention, the glove sleeve includes externally a determined number of clip-on contacts located on the flexible sectors and the cuff sleeve whose inner surface is unobstructedly cylindrical, includes internally a same number of bayonet type helical ramps for guiding the clip-on contacts on the anchor cavities, latching the glove sleeve into the cuff sleeve, forming, once assembled, a sealed whole called a wrist ring. 
         [0024]    The clip-on contacts of the glove sleeve are engaged in the helical grooves of the cuff sleeve. The contacts mounted on flexible sectors are clipped into small cavities latching the glove sleeve in the cuff sleeve, such that the sealed whole forms an undissociable wrist ring. 
         [0025]    The glove interchangeability does not require any tooling. 
         [0026]    The interchangeability for a new glove is made by introducing the contacts of the glove sleeve body in the peripheral inlets of the helical grooves of the cuff sleeve in a synchronised manner, cancelling tenons come to cancel the contacts of the glove sleeve to be changed, releasing them and by a rotation of about 40° clockwise by following the helical grooves of the cuff sleeve come to be clipped and latch the new glove sleeve while releasing the old one. 
         [0027]    A static and dynamic sealing, during interchangeability, consists advantageously at least of a seal, for example having lobes and a O-ring, either injected or sealingly embedded in the throat of the glove sleeve provided on the glove sleeve body, in order to ensure a permanent sealing between the cuff sleeve and the glove sleeve. 
         [0028]    This sealing is continuously held upon changing the glove sleeve. 
         [0029]    The slipperiness of the seal elastomer between the cuff collar and the glove collar is improved by a surface ionisation which has the advantage to harden the elastomer only at the surface and to decrease the friction coefficient, increasing its durability and its resistance to sterilising products. Bombarding the elastomer during the surface ionisation with silver ions makes the surface active to the neutralisation of bacteria, which brings about two significant advantages: slipperiness and an antibacterial action, the combined translation/rotation movement of the glove sleeve against the inner wall of the cuff sleeve body is thus achieved without strain and enhances the integrity of the glove change by its antibacterial action. 
         [0030]    Preferably, the device for changing the glove including a seal with lobes of elastomer has undergone a surface ionisation enabling its slipperiness properties to be improved facilitating the placement of a new collar and the ejection of the old one. 
         [0031]    It includes clip-on contacts ( 49 ) and contact cancelling tenons ( 47 ) provided with a visual and mechanical foolproofing system, such that the glove is always put into the right working position. 
         [0032]    The device for changing the glove does not require any specific tool to perform the interchangeability handling by the operator, visual marks are used for facilitating displaying during interchangeability actions being performed by a translation followed by a rotation of about 40°. 
         [0033]    Preferably, the device for changing the glove includes a latching system consisting of clip-on contacts introduced into appropriate cavities. These clip-on contacts can be unclipped only when cancelling tenons are introduced into housings of the flexible sectors to cancel to inside the glove sleeve, this action resulting in unclipping these clip-on contacts. 
         [0034]    Preferably, the device for changing the glove includes a glove sleeve consisting of a glove sleeve body including the devices for guiding and latching this glove sleeve body in the cuff sleeve body. It includes a glove assembling collar of the glove into the glove sleeve body, the holding being ensured by gluing the glove assembling collar in the glove sleeve body. 
         [0035]    The sealing between the glove sleeve body and the glove assembling collar is ensured by pressing the elastomer of the glove and the gluing resin between both elements. 
         [0036]    Preferably, the device for changing the glove consists of the cuff sleeve body and a cuff assembling collar. The assembling collar comes to press the sleeve against the cusp of the cuff sleeve body, thus ensuring the sealing of the cuff sleeve, the whole being held by a resin type glue making them undissociable. 
         [0037]    Another main object of the invention is a method for replacing a used glove with a new glove by means of a device as previously described. 
         [0038]    It comprises the following phases:
       a new glove equipped with its glove sleeve is placed inside the containment envelope;   both cuff sleeve assembling and glove assembling collars are secured to each other by snapping them;   the new glove sleeve is pushed and rotated as a single piece in the used glove sleeve to the cuff sleeve until the new sleeve is latched in the helical ramps of the cuff sleeve body until the visual positioning provided is reached and a “click” for latching and full clearing of the used glove sleeve from inside the sleeve is heard.       
 
         [0042]    On the slice of the used glove sleeve body, at least three female slots are provided for accommodating the three male slots for driving the new glove sleeve in the proper position, that is thumb upwards. Three housings are also provided in the flexible sectors accommodating the tenons of the new glove sleeve for unclipping the contacts of the used glove sleeve. 
         [0043]    The interchangeability does not require any tooling in the case of a two-glove working station. It is sufficient to take the new glove sleeve with the other hand through the glove, to display it on the wrist ring along the marks provided on the cuff and glove sleeves, to engage the contacts into the helical grooves by holding the faces of the glove sleeves against each other and to push/rotate. The used glove sleeve is discharged as the translation and rotation proceed, the new glove sleeve is clipped and the used glove sleeve falls inside the cuff. 
         [0044]    Preferably, the security at the end of the cycle rotatably stops the new glove sleeve with respect to the cuff sleeve, it is ensured by locking the contacts into cavities therefor, prohibiting any radial and axial movement. The operator is ensured of the proper latching of the glove sleeve by an auditory signal being “click” and an indicator of visual positioning. Both these signals prove that the glove is actually latched in a right position. 
         [0045]    Advantageously, the seal of elastomer contains a decontaminant agent which neutralises possible bacteria that can come from inside the sleeve, advantageously the seal because of its configuration will provide sealing for the connection. 
         [0046]    According to the process for replacing a used glove with a new glove by means of a device according to the invention:
       in the case of the use of a depressurised system, the sleeve is then pulled out to outside the cell, whereas in the case of the use of a pressurised system, the used glove is pulled out to outside the cuff;   in the depressurised case, the new glove is pulled out to inside its sleeve;   a new glove equipped with its glove sleeve is placed inside the containment cell (Insulator) in the pressurised case and outside in the depressurised case;   in both cases, pressurised and depressurised, the new glove sleeve is displayed to the used glove sleeve in place in the cuff sleeve body making sure to align the mark of the new sleeve with the mark of the cuff sleeve body. The slops at the inlet of the housings enabling the tenons to be pre-centred;   the new glove sleeve is pushed to the old glove sleeve, which results in engaging the male slots in the female slots of the old glove sleeve and in the same movement, in engaging the cancelling tenons into the housings of the old glove sleeve. This results in cancelling the clip-on contacts to inside the previous glove sleeve;   both glove sleeves are rotated as a single piece (this is made possible by the male and female slots) by a rotation of about 40° in the cuff sleeve body, thus making latching the new glove sleeve into the cuff sleeve body, under the effect of the clip-on contacts in the helical ramps of the cuff sleeve body, up to the visual positioning of the new glove sleeve in alignment with the mark for the latching end located on the cuff sleeve body, indicated by a “click”.       
 
         [0053]    The used glove sleeve is cleared off the inside the cuff in the case of the use of the pressurised system. In the case of the use of the depressurised system, the used glove sleeve is cleared off inside the glove box.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0067]    Marks followed by the letter “a” designate the mounted pieces for a pressurised operation. Marks followed by the letter “b” designate the mounted pieces for a depressurised operation. 
         [0068]    The same pieces afford to make a mounting for the pressurised cells, as well as for the depressurised cells by inverting the cuff sleeve body  21   a  (pressurised mounting) or  21   b  (depressurised mounting) and the glove sleeve body  40   a ,  40   b . In the case of the depressurised cell mounting, the glove  60   b  is pulled out on its assembling collar  42   a  or  42   b.    
         [0069]    In  FIG. 1 , is represented a device for changing a pressurised handling glove. This device is attached to a shoulder ring  4  sealingly mounted to a wall  2  of a containment envelope in the present case, the cuff  6  being attached to the shoulder ring by a collar  5 . The cuff  6  can be attached to the shoulder ring by any other appropriate method, for example by anchoring in a cavity by silicone injection, by pinching the skin of the cuff  6  by a glued intermediate piece, by gluing or by welding depending on the materials present. At its end opposite to that attached to the glove ring, the cuff  6  is attached to a cuff sleeve  20   a  in which a glove sleeve  40   a  is mounted. A glove  60   a  is attached to the glove sleeve  40   a . The assembly formed by the cuff sleeve  20   a  and the glove sleeve  40   a  is called a wrist ring  10   a.    
         [0070]    The glove  60   a  is mounted to the glove sleeve  40   a  by any appropriate method, and in particular it can be mounted by anchoring and pinching by means of an assembling collar pressed and glued in the glove sleeve. 
         [0071]    The internal volume of the cuff  7  corresponds to the outer atmosphere of the glove box. 
         [0072]    In  FIG. 2 , is represented the mounting of the wrist ring affording with the same pieces an interchangeability from inside to outside, corresponding to a use of a pressurised glove box, used in particular in pharmacy. 
         [0073]    In  FIG. 3 , is represented the mounting of the wrist ring affording with the same pieces to perform an interchangeability without particular tool from outside to inside corresponding to a use of a depressurised glove box. The cuff sleeve body  21   b  is inverted, the cuff  6  is attached in a way identical to  FIG. 2 . The glove sleeve  40   b  is displayed by inside the cuff which implies to mount the glove  60   b  by turning it back to its assembling collar  42   b.    
         [0074]    Hereinafter, is considered the case of a pressurised cell (in this case, the marks of the pieces are followed by the letter a). The glove changing is thus made from inside to outside the envelope. 
         [0075]      FIG. 4 a    represents the glove sleeve  40   a  consisting of a glove sleeve body  41   a  on which a seal  43  is mounted in a throat. A glove  60   a  without a flange is fitted to its glove assembling collar  42   b , the assembly being inserted into the glove sleeve body  41   a  in a sealed manner by pressing and gluing or welding, making it undissociable from its glove assembling collar  42   b  thus forming the glove sleeve  40   a.    
         [0076]      FIG. 4 b    represents the cuff sleeve  20   a  consisting of a cuff sleeve body  21   a  on which is mounted above a cusp  23  the cuff  6 , the assembling collar of the cuff sleeve  22   a  being inserted on the cuff sleeve  21   a  in a way identical to the glove assembling collar  42   a.    
         [0077]      FIG. 4 c    represents the glove sleeve  40   a  manually placed without particular tool in the cuff sleeve  20   a  thus forming the wrist ring  10   a.    
         [0078]      FIG. 5  shows the wrist ring cuff  10   a  and glove  60   a  assembly properly mounted, thumb vertically directed upwards. 
         [0079]      FIG. 6  at an enlarged scale enables details of the wrist ring  10   a  to be viewed with the cuff sleeve  20   a  and the glove sleeve  40   a , the volume between both these sleeves enabling a proper gas penetration for fully sterilise this space. It ensures a proper decontamination of the uncovered surfaces. Depending on the operations to be performed for example in the animal field, the protection of this volume is self-evident to avoid any introduction detrimental to the system interchangeability.  FIG. 6  enables the following figures to be better apprehended.
         FIG. 7  represents the cuff sleeve body  21  alone.       
 
         [0081]    The inside includes a clearing bore  28  in which at least three inlets  29  of helical ramps  30  preferably offset by 120° are located. These does not open to outside the cuff sleeve body  21 . This clearing bore  28  is slightly greater than the bore  27  in order to avoid damaging the seal upon passing at the helical ramps  30  and enables the glove sleeve  40  a to be more readily introduced by the operator. 
         [0082]    At the end of these helical ramps is an anti-unsealing spur  31  of a rectangular shape in the circular direction followed by a cavity  37  terminating the helical ramps  30 , making possible to clip clip-on contacts  49  accommodated in the cavities  37 . The function of the anti-return spur  31  is to prevent it from being unsealed upon passing in the groove  58 . The functions of the cavity  37  are to hold in the latched position the glove sleeve body  41   a / 41   b  on the cuff sleeve body  21  and to generate the resonance of a “click” at the operator, confirming latching. Further, visual marks are located, the one  36  on the cuff sleeve body  21 , the other  51  located on the glove sleeve body  41   a / 41   b , it confirms this position by their alignment. The anti-return spurs  31  thus act as anti-return stopping any axial and radial movement between the cuff sleeve  20   a / 20   b  and the glove sleeve  40   a / 40   b.    
         [0083]    An engagement mark  38  enables the operator to bring visually the glove sleeve  40   a / 40   b  on the cuff sleeve  21 , facilitating its engagement in the clearing bore  28 . The bore  27  receives the seal  43  and ensures a continuous dynamic sealing throughout the interchangeability phase and then a static sealing. 
         [0084]    The outside of the cuff sleeve body  21  comprises a first shoulder, on which the marks  36  and  38  are found, and which includes after these marks, a throat  25  enabling the glue deposit or the flow of material to be received in the case of a welding assembly. This is followed by a second throat called a sleeve end  24  avoiding a complex mounting of the cuff  6  to its cuff body  21 . This housing is followed by a shoulder called a cusp  23  for holding the cuff. Finally, behind this cusp  23  on its outside of the ferrule  26 , is found the symmetry of the throats  24  and  25  with a cuff end throat  24 ′ and with a throat  25 ′ enabling the system to be used in the case of a depressurised glove box. 
         [0085]      FIG. 8  represents alone the collar for assembling the cuff sleeve  22  to the cuff sleeve body  21 , the centring inside bore  32  ensuring the centring on the cuff sleeve body  21 . The shoulder  33  comes against the cusp  23  enabling the cuff to be held by pressure as the gluing or welding sets. Further, this shoulder  33  has a very important second function, that of protecting the cuff  6  against shocks resulting in an increased lifetime. 
         [0086]      FIG. 9  represents alone the glove sleeve body  41 . This ferrule shaped piece ensures the following functions:
       unclipping by the three contact cancelling tenons  47  located behind the glove sleeve body  41 , when engaged in the three housing pairs  52 ;   rotatable driving by three driving male slots  46  also located behind the glove sleeve body  41  and the three driving female slots  45  located at the front of the glove sleeve body  41  enabling the male slots  46  of the new glove sleeve  41  to be received;   clipping by three clip-on contacts  49  located on the three flexible sectors  48  at the front of the glove sleeve body  41 ;   reception of the contact cancelling tenons of the new sleeve of the new glove by the three housings  52 , the gradual penetration of which during the placement of this new sleeve of a new glove by the operator results in that the tenons  47  radially cancel inside the glove sleeve body the clip-on contacts by virtue of the deformation of the flexible sectors  48 . This flexibility is made possible by the three through ports  50 ;   sealing between outside the glove sleeve  41  and inside the cuff sleeve body  21 . For this, a throat  44  makes it possible to receive the lobe type seal  43  in the example represented, but it can be lipped etc. This seal  43  should be made of a food material, rubber etc. (see  FIG. 6 ). The sealing is ensured by the compression of the lobes of the seal  43  against the smooth inner wall of the bore  27  of the cuff sleeve body  21 . The elastomer slipperiness is achieved by a surface ionisation which has the advantage to harden the elastomer of the surface and to increase the slipperiness by decreasing the friction coefficient. The ionisation can be made with auto-bactericide silver ions, which enables the part of the seal  43  in contact with inside the cuff sleeve body  21  to be kept sterile;   visual display of the glove sleeve  40  on the cuff sleeve, by virtue of a mark  51  on outside the cylindrical part of the sleeve body  41  and on the front slice;   sealing of the glove mounted on its assembling collar  42  (see  FIG. 10 ) bearing against the inner shoulder  53  of the glove sleeve body  41 ;   undissociable holding of the glove by epoxide resin type gluing or the like, depositing or injecting glue is provided in a space  55  formed by the inner cusp  54  of the glove sleeve body  41  and the centring ferrule  57  of the glove assembling collar  42 .       
 
         [0095]      FIG. 9 a   , for a better understanding, represents a magnified detail of a flexible sector  48  with its clip-on contact  49 , its housing  52  for receiving the cancelling tenons  47 , and the groove  58  and the port  50 .
