The innovation disclosed herein relates to a glove donning system and a glove packaging assembly.
Disposable gloves have been utilized in the health care industry, scientific industry and elsewhere for many years. In health care, the use of gloves by a heath care provider protects the health care provider from possible contamination resulting from handling a patient. In addition, a glove that is clean on the outside protects a patient from contaminants that may reside on the hands of the health care provider. In any contamination-sensitive usage, special precautions must be taken to insure that the user does not contaminate the gloves as they are being donned and that other stored gloves are not contaminated or touched by the user.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements or to delineate the scope of the innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later.

The innovation disclosed herein dispenses and holds open a clean glove, allowing a user to don the glove without touching the outside of the glove, thus preventing possible contamination of the outside of the glove. Unlike a traditional glove box, the innovation also keeps other stored gloves that are ready to be dispensed from becoming contaminated, as these gloves remain protected until ready to don.
In alternate embodiments, the glove donning systems 10, 18 may be configured with multiple sets of grabber assemblies 69, 70 and glider assemblies 13 operating within the same housing 11, and are configured to retrieve and process at least two gloves 16 within the same donning sequence.
Still referring to
In an alternate embodiment, the lifter screw 53 may be raised and lowered in the manner of a block and tackle hoist activated by a rotating motor.
The conveyance assembly 12 may also contain a glove box loading switch 66 that includes a switch located in a position to indicate the correct loading of the back of the glove box base 144. When the switch is activated by contact with or proximity to the glove box base 144, a signal is generated to notify the user that the glove box base 144 has been positioned correctly.
In one embodiment, the track set 19 illustrated in FIG. 4C1 includes the thread surfaces of the lifter screw 53. The track set 19 cooperates with the glove insert card alignment feature 135 of
In another embodiment illustrated in
In another embodiment, the track set 192 comprising a rod or rods 191 supports the glove assembly 15, without conveyance, at the ready position for the donning sequence with the rod or rods 191 being angled, curved, flat or any combination thereof.
In another embodiment,
The alternate lifter motor assembly 231 replaces the pivotable insertion actuator 49. The motor 206 is fixedly attached to the motor mount 214. The motor shaft 208 is fixedly coupled to the screw 204 by a coupling 207. The nut 205 cooperates with the screw 204 to translate when the screw 204 rotates. The nut 205 is fixedly attached to the bracket 212, which is guided by the linear bearing 210 along the guide 209. Two bracket pins 213 on either side of the bracket 212 rotatably connect to the trunnion 203, which is rotatably pinned to the lifter arm 50A with the trunnion pin 215. Pulling or pushing motion is achieved by rotating the screw 204 with the motor 206. As the screw 204 rotates, the nut 205 translates toward or away from the motor 206, forcing the lifter arm 50A to follow.
The front-to-back driver motor 71 drives the front-to-back driver pulley 75 which drives the front-to-back belt 73 supported by the front-to-back idler pulley 74. The front-to-back belt 73 is anchored to at least one of the right or left front-to-back gliders 76, 77 and pulls the front-to-back glider assembly 67 forward and back.
In an alternate embodiment, the glider assembly 13 positioning system could be or include a pair of articulated arms.
Mounted upon the transverse glider shafts 83 is the transverse glider assembly 68 which includes a right and left transverse glider 84, 85. The right and left transverse gliders 84, 85 contain bushings or bearings 86 to facilitate low friction motion along the transverse glider shafts' 83 direction with clearance holes 87 through the right and left transverse gliders 84, 85 to allow the transverse glider shafts 83 to pass through. Mounted on the ends of the right and left transverse gliders 84, 85 are the respective right and left grabber assemblies 69, 70 and the right and left grabber assembly rotation motors 88, 89.
The transverse glider assembly 68 further includes a lead screw 90 that has a thread 91 on one side and a reverse thread 92 on the other side, and a transverse driver assembly 93 which includes a transverse driver motor 94 and a transverse driver gearbox 95. The right and left transverse gliders 84, 85 further include threaded and reverse threaded inserts 39, 96 that engage with the lead screw 90. Alternately, threaded holes 96A and reverse threaded holes 39A can be used instead of threaded and reverse threaded inserts 39, 96.
An alternate approach was previously disclosed in
The right and left transverse gliders 84, 85 are driven by the transverse driver assembly 93. The transverse driver gearbox 95 is rotationally coupled to the lead screw 90 and is driven by the transverse driver motor 94. Engagement of the thread 91 portion and the threaded insert 96 and the reverse thread 92 portion and the reverse threaded insert 39 will cause the right and left transverse gliders 84, 85 to move towards each other or away from each other when the lead screw 90 rotates. The right and left transverse gliders 84, 85 have rotation holes 97 co-radially fitted with rotation bushings 98. The right and left transverse gliders 84, 85 have rigidly attached right and left grabber assembly rotation motors 88, 89.
The right motor and belt system 233 includes a belt 222, a drive pulley 226, a motor 224, a motor shaft 229, a transverse glider block 230, right and left front-to-back glider blocks 76A, 77A, and an idler pulley 228. The motor 224 is fixedly attached to the right front-to-back glider block 76A, and includes a rotatable motor shaft 229. The drive pulley 226 is rigidly attached to the motor shaft 229. The belt 222 is rigidly attached to the right transverse glider block 230 and cooperates with the driver pulley 226 and idler pulley 228. The idler pulley 228 is rotatably fixed to the front-to-back glider block 77A. The motor shaft 229 drives the drive pulley 226, which drives the belt 222, causing the transverse glider block 230 to travel in the direction of the attached belt 222 movement. The belt 222 is supported by the idler pulley 228.
Because the right and left grabber assemblies 69, 70 are constructed and operate in a mirrored fashion, this description will proceed with the understanding that the right grabber assembly 69 descriptions will apply to the left grabber assembly 70 in a mirrored fashion.
The grabber assembly further includes a slotted tube 107 with an inner bore 108 and at least one transverse slot 109. The grabber 110 is rigidly attached to the slotted tube 107. The slotted tube 107 passes through the pincher 111 and is rigidly attached to the guide bar support 116, and rotatably passes through the right and left slotted tube bearings 105, 106. A pincher slider bushing 113 is rigidly mounted in the clearance bore 114 and rides over the slotted tube 107. A guide bar bushing 115 is rigidly mounted in the pincher 111. The guide bar 112 is rigidly mounted in the guide bar support 116 and passes through the guide bar bushing 115 and rigidly terminates in the grabber 110. The guide bar 112 is parallel to the slotted tube 107. A pincher drive screw follower 117 rides inside the slotted tube inner bore 108. The pincher drive screw follower 117 is threaded on the inside diameter and contains at least one transverse hole 118 joined with at least one pincher pin 119 to the pincher 111. The pincher pin 119 may have an orientation feature.
A pincher screw 120 inserts through the pincher screw right bearing 121, the pincher driven gear 122, and the slotted tube 107, and is supported on the end by the pincher screw bushing 123 contained in the grabber 110. The pincher screw right bearing 121 inserts into the right end of the slotted tube 107. The pincher drive screw follower 117 is threaded onto the pincher drive screw thread 124 and translates through the inner bore 108 when the pincher screw 120 rotates. The grabber driver gear 157 is rigidly affixed to the grabber raiser motor shaft 125. A pincher driver gear 126 is rigidly affixed to the pincher motor shaft 127.
The grabber belt 128 is driven by the grabber driver gear 157 and drives the grabber driven gear 142, which is rigidly attached to the slotted tube 107 and is contained between the grabber frame bearing flanges 101. The pincher belt 129 is driven by the pincher driver gear 126 and drives the pincher driven gear 122, which is rigidly attached to the pincher screw head 130. The grabber 110 and pincher 111 are raised and lowered by the rotation of the slotted tube 107. The slotted tube 107 is rotated by the grabber raiser motor 104 through the grabber driver gear 157, grabber belt 128, and grabber driven gear 142, and is supported by the right and left slotted tube bearings 105, 106.
The guide bar 112 rotates about the slotted tube 107 and maintains grabber 110 and pincher 111 alignment rigidity. The pincher 111 translates along the slotted tube 107 and guide bar 112 moving away from or towards the grabber 110. The pincher motor 103 drives the pincher driver gear 126, the pincher belt 129, the pincher driven gear 122, and the pincher screw 120. As the pincher screw 120 rotates, the pincher drive screw follower 117 is forced to translate inside the slotted tube 107 along the pincher drive screw thread 124 and pulls the pincher 111 linked to the pincher drive screw follower 117 through the pincher pin 119. The pincher pin 119 rides in the transverse slot 109 of the slotted tube 107, preventing rotation of the pincher drive screw follower 117 relative to the slotted tube 107. Alternatively, the pincher pin 119 can be any shape that will follow in the transverse slot 109.
The right grabber assembly rotation motor 88 is coupled to the grabber assembly rotation gear 102. Rotation of the right grabber assembly rotation motor 88 rotates the grabber assembly rotation gear 102 and then rotates the right grabber assembly 69.
FIGS. 6C1-6C3 illustrate an alternate pincher translation driver 234. The alternate pincher translation driver 234 includes a slotted tube 107A, which contains a slot 109A. A follower 219 is mounted on the pincher 111A and is pushed in place by a spring 220, which is held in place by a follower keeper plate 221. The follower 219 is threaded on the pincher screw 120A side with a mating thread that cooperates with the pincher screw 120A. The follower 219 is captive in the pincher 111A. Rotation of the pincher screw 120A drives the follower 219 along the pincher screw 120A, forcing the pincher 111A to follow.
The glove 16 further includes a glove wrist 188 where the glove wrist 188 is installed over the glove insert card 131 through the glove opening 187 where the glove opening perimeter 140 conforms into the area of the glove insert card insets 136.
FIGS. 8A1-8A8 and 8B disclose gloves 16 packaged in a glove container or box 143 which includes a glove box base 144 and a box lid 145. A wrapper 146 may enclose the glove box 143. In an alternative method, a seal may include adhesively bonded tape or stickers sealing the box lid 145 to the glove box base 144. The glove box 143 contains glove assemblies 15 and one or more glove assembly alignment fixtures 147 cooperating with the glove insert card alignment feature 135. Glove assembly alignment fixtures 147 may be enclosed or semi-enclosed hollow tubular fixtures. In another example embodiment, glove assembly alignment fixtures 237 that engage and align the glove assemblies 15 may be affixed to or included in the glove container. In one configuration, the box lid 145 extends over the top and sides of the glove box base 144. The glove box base 144 has box cutaway portions 148 to allow access to the gloves 16. The box back 149 may have one or more alignment fixture support features, such as notched cutaways 150 at the top to accommodate or support the glove assembly alignment fixture 147. The box lid 145 may have box lid cutaways 151 to facilitate removal of the box lid 145 from the glove box base 144. One or more insert termination cards 152 with one or more alignment features 153 may be inserted in the front, back, or front and back of the glove box 143 to protect the gloves 16 during box handling, and to allow loading of the glove box 143 into the glove donning system 10 in a front-to-back or back-to-front orientation. The glove box 143 can be a container and/or a flexible covering such as a bag or wrapper.
The glove assembly alignment fixture 147 may be an enclosed or semi-enclosed hollow tubular fixture that maintains the alignment of the glove insert card alignment features 135 of the glove insert cards 131. During packaging, both ends of the glove assembly alignment fixture 147 may be folded down towards the bottom of the glove box base 144 to allow the box lid 145 to be placed over the glove box base 144 and the glove assembly alignment fixture 147. Upon removal of the box lid 145, the user may unfold the glove assembly alignment fixture 147 to allow the user to slide the glove assembly alignment fixture 147 with accompanying glove assemblies 15 and glove box base 144 over the lifter rod 53 and track set 19.
As the user slides the glove assembly alignment fixture 147 with accompanying glove assemblies 15 and glove box base 144 over the track set 19, the proper placement of the glove box base 144 may be signaled by the activation of the glove box loading switch 66. When the glove box base 144 is in the proper position, the user presses on the insert termination card 152 and removes the glove assembly alignment fixture 147, allowing the glove assemblies 15 to transfer onto the track set 19 in the proper position. The insert termination card 152 is then removed by the user. The insert termination card 152 may have an alignment feature 153 and may contain insert termination card shoulders 154 on either side. The insert termination card 152 may contain a fold-over portion 155 and a slit 156 from the alignment feature 153 to the edge of the fold-over portion 155 to facilitate removal from the track set 19.
In one approach, the glove insert card alignment feature 135 is one or more apertures defined in the glove insert card 131, and the glove assembly alignment fixture 147 may be one or more enclosed or semi-enclosed tubular hollow fixtures. In another approach the glove insert card alignment feature 158 is shown as a pair of opposing insets on the glove insert card 160 and the glove assembly alignment fixture 159 is a structure with opposing surfaces mating to the opposing glove insert card alignment features 158.
FIGS. 9A1-9A5 illustrate a glove donning system 10 containing a card alignment assembly 172. The card alignment assembly 172 includes a card alignment bar 161 having a proximate (first) end 161A attached to the housing 11, a card alignment bar contactor 162 attached to a distal (second) end 161B of the card alignment bar 161, a card alignment frame bracket 163, a card alignment transverse frame 164, a card alignment shaft 165, a card alignment receiver bracket 166, a card alignment pin 167, a rest 168, and one or more card alignment pin bases 169.
The pair of card alignment bars 161 may be positioned on either side of the track set 19. The card alignment bar contactors 162 extend below the card alignment bars 161. The card alignment bar contactors 162 maintain glove insert card shoulder 138 alignment by resting on or near the card edge control points 189. The card alignment bars 161 terminate into the card alignment frame brackets 163.
The card alignment frame brackets 163 are rigidly connected by the card alignment transverse frame 164. The card alignment shaft 165 is rigidly connected normal to the card alignment frame bracket 163 on one side of the housing. The card alignment pin 167 is connected normal to the card alignment frame bracket 163 and is co-radial with the card alignment shaft 165 in the opposing direction.
The card alignment receiver bracket 166 is rigidly connected to the card alignment shaft 165, such that the card alignment shaft 165 extends beyond the card alignment receiver bracket 166, and is positioned to receive the card alignment hinge contactor 170. When the maintenance door hinge 47 is rotated up, the card alignment hinge contactor 170 pushes on the card alignment receiver bracket 166, rotating the card alignment shaft 165, which raises the card alignment bars 161 and provides access for maintenance and glove assembly 15 loading. When the maintenance door 26 is lowered, the card alignment hinge contactor 170 rotates clear of the card alignment receiver bracket 166 and the card alignment bars 161 rotate back to the rest position through the force of gravity.
The card alignment pin base 169 includes an opening 171 defined therein that is adapted to accept a pin or shaft. The card alignment pin base 169 is rigidly connected to the housing 11. One card alignment pin base 169 is positioned on one end of the card alignment assembly 172 and accepts the card alignment pin 167. Another card alignment pin base 169 is positioned at the opposing end of the card alignment assembly 172 and accepts the free end of the card alignment shaft 165. A rest 168 may be positioned below the card alignment frame bracket 163 and is rigidly attached to the housing 11, such that when the card alignment bar contactor 162 is in its fully down position, it rests at or near the card edge control points 189. In an alternate approach, the card alignment shaft 165 may be replaced with one or more card alignment pins 167.
The shaft 180 is co-radial to the hinge pin 200 and is rigidly attached to the maintenance door hinge 47 and the top pulley 177. The cable 179 is rotationally coupled to the top pulley 177 such that the cable 179 wraps around the circumference of the top pulley 177 as it rotates. The cable 179 extends from the top pulley 177 down to the bottom pulley 178. The bottom pulley 178 face is orthogonal to the top pulley 177 face.
The cable 179 follows the circumference of the bottom pulley 178, thus changing direction from a downward direction to a direction towards the glove box base 144, and terminates and is flexibly affixed to the tension arm 184 of the arm assembly 176. The tension arm 184 is rotatably pinned to the base 182. The spring 185 is affixed to the base 182 and to the tension arm 184 pulling the spring 185 in tension. A contactor 186 is attached to the end of the tension arm 184.
When the maintenance door 26 is raised, the maintenance door hinge 47 rotates, rotating the shaft 180, which then rotates the top pulley 177. The cable 179 winds up around the top pulley 177 and slides over the bottom pulley 178, which pulls the tension arm 184 away from the glove box base 144. When the maintenance door 26 is lowered, the tension is lessened on the cable 179 and the spring 185 pulls the arm towards the glove box base 144, engaging the contactor 186 to the side of the glove box base 144. When both the right and left contactors 186 press against the glove box base 144, the glove box base 144 deforms, thus preventing forward motion of the glove box base 144. When the tension arms 184 are pulled away from the glove box base 144, the glove box base 144 is free to move forward and backward. As illustrated in
Referring to
In the method description below, since the right and left grabber assemblies 69, 70, the right and left transverse gliders 84, 85, and the right and left front-to-back glider blocks 76, 77 operate in a mirrored fashion on opposite sides of the glove 16 in the glove donning system 10, the description below will proceed with respect to the right grabber assembly 69, the right transverse glider 84, and the right front-to-back glider block 76, with the understanding that it also applies to the left grabber assembly 70, left transverse glider 85, and left front-to-back glider block 77.
Thus, at 1302, the activation device 41 is activated by the user. At 1304, the activation device transmits a signal to the control system 236, and at 1306, the control system 236 initiates a glove donning sequence, as illustrated in
