- Referring to
FIG. 1A , there is shown apatient therapy system 2 according to the principles of the present disclosure. Thepatient therapy system 2 comprises a control unit 4, ahead wrap 100, and aconnector 10. In operation, a heat transfer fluid is deposited in the control unit 4 via anaperture 14. The heat transfer fluid is cooled or heated by the control unit 4 and pumped to the head wrap 100 by connector tube 6. The heat transfer fluid flows into thehead wrap 100 through an inlet port, and exits through an outlet port to the control unit 4 via theconnector 10 andconnector tube 9. Similarly, a gas may be pumped by the control unit 4 to thehead wrap 100 through the connector tube 7 and theconnector 10 to provide compression. The connector tube 7 supplying gas is positioned between the connector tube 6 and theconnector tube 9 supplying heat-transfer fluid. In this manner, the connector tube 7 supplying gas insulates the connector tube 6 from theconnector tube 9. In addition, additional connector tubes may be present to allow for both heat transfer fluid and gas to be passed to the blanket for simultaneous temperature therapy and compression therapy. - The control unit 4 receives data and manipulates any one of a plurality of therapeutic characteristics of the head wrap 100 based on the data. The
head wrap 100 is adapted for the administration of hot, cold, and/or compression therapies to a body portion of the patient. Theconnector 10 provides a fluid and/or gas connection between the control unit 4 and the head wrap 100 for the transfer of gas and heat transfer fluid. Theconnector 10 may also allow for transfer of electrical sensor signals and/or data signals between thehead wrap 100 and the control unit 4. -
FIG. 1B is an exterior plan view of anillustrative head wrap 100 in an unfolded configuration in accordance with one or more aspects of the disclosure. Thehead wrap 100 includes abody 102. Afirst arm 104 and asecond arm 106 extend laterally from thebody 102 in generally opposite directions. Thefirst arm 104 and thesecond arm 106 share a common centralhorizontal axis 110. Acenter section 108 extends from thebody 102 such that a centralvertical axis 112 of thecenter section 108 is generally perpendicular to the centralhorizontal axis 110 of thefirst arm 104 and thesecond arm 106. In various embodiments, however the centralvertical axis 112 of thecenter section 108 may be angled relative to the centralhorizontal axis 110 of thefirst arm 104 and thesecond arm 106. Afirst panel 114 and asecond panel 116 extend from thefirst arm 104 on the same side as thecenter section 108. Afirst panel axis 118 is angled relative to the centralhorizontal axis 110 such that angle α is less than approximately 90 degrees. Asecond panel axis 120 is angled relative to the centralhorizontal axis 110 opposite thefirst panel axis 118 such that an angle β is less than approximately 90 degrees. - Still referring to
FIG. 1B , athird panel 122 and afourth panel 124 extend from thesecond arm 106 on the same side as thecenter section 108. Athird panel axis 126 is angled relative to the centralhorizontal axis 110 such that an angle γ is less than approximately 90 degrees. Afourth panel axis 128 is angled relative to the centralhorizontal axis 110 opposite thethird panel axis 126 such that an angle φ is less than approximately 90 degrees. Thefirst panel axis 118 and thethird panel axis 126 are arranged generally parallel to each other. Likewise, thesecond panel axis 120 and thefourth panel axis 128 are arranged generally parallel to each other. However, thefirst panel axis 118, thesecond panel axis 120, thethird panel axis 126, and thefourth panel axis 128 could be arranged in any orientation. Afirst securement tab 130 extends from thethird panel 122 and asecond securement tab 132 extends from thefourth panel 124. In other embodiments, however, thefirst securement tab 130 could extend from thesecond panel 116 and thesecond securement tab 132 could extend from thefirst panel 114. - Still referring to
FIG. 1B , a firstfluid port 134 and a secondfluid port 136 are disposed on thebody 102 on opposite sides of the centralvertical axis 112. Acompression port 138 is disposed on thebody 102 proximate the centralvertical axis 112. The firstfluid port 134 and the secondfluid port 136 are fluidly coupled to a source of a heat-transfer fluid via afirst tube 140 and asecond tube 142, respectively. During operation, the firstfluid port 134 facilitates delivery of the heat-transfer fluid to thehead wrap 100 and the secondfluid port 136 facilitates removal of the heat-transfer fluid from thehead wrap 100. In various embodiments, however, the fluid flow is reversed such that the secondfluid port 136 facilitates delivery of the heat-transfer fluid to thehead wrap 100 and the firstfluid port 134 facilitates removal of the heat-transfer fluid from thehead wrap 100. Thecompression port 138 is fluidly coupled to a source of compressed gas via athird tube 144 and facilitates delivery of the compressed gas to thehead wrap 100. Thefirst tube 140, thesecond tube 142, and thethird tube 144 are of sufficient length to allow the wearer to position thefirst tube 140, thesecond tube 142, and thethird tube 144, for example, over the wearer's shoulder area and in front of the wearer. In other embodiments, thefirst tube 140, thesecond tube 142, and thethird tube 144 are of sufficient length such as, for example, several feet, to connect to the control unit 4. Thefirst tube 140 and thesecond tube 142 include afirst coupler 143. Thethird tube 144 includes asecond coupler 145. Use of thefirst coupler 143 and thesecond coupler 145 ensures that thefirst tube 140 and thesecond tube 142 cannot be connected to a, for example compressed gas source and, likewise, that thethird tube 144 cannot be connected to, for example, a heat-transfer fluid source. Thefirst coupler 143 and thesecond coupler 145 are, in a typical embodiment, keyed to thefirst tube 140, thesecond tube 142, and thethird tube 144, respectively. Additionally, thefirst coupler 143 and thesecond coupler 145 are, during use, within reach of the wearer, thereby allowing the wearer to disconnect thehead wrap 100 without assistance. -
FIG. 1C is a cross sectional view of theillustrative head wrap 100 in accordance with one or more aspects of the disclosure. Thehead wrap 100 includes afirst layer 153 that is formed of a flexible material such as, for example, nylon, urethane, or polyvinyl chloride (PVC). Thefirst layer 153 is adapted to be placed in contact with the wearer's scalp. Thefirst layer 153 includes a first-layer perimeter 155. Asecond layer 157 is positioned adjacent to thefirst layer 153 and includes a second-layer perimeter 159 that aligns with and is bonded to the first-layer perimeter 155 such that afluid bladder 150 is defined in the head wrap 100 between thefirst layer 153 and thesecond layer 157. A plurality ofsecond bonds 167 are formed interior of the first-layer perimeter 155 and the second-layer perimeter 159. The plurality ofsecond bonds 167 are, for example, circular in shape and join thefirst layer 153 to thesecond layer 157 at a plurality of intermediate points interior of the first-layer perimeter 155 and the second-layer perimeter 159. During operation, the plurality ofsecond bonds 167 create a plurality of fluid flow paths through thefluid bladder 150. Additionally, the plurality ofsecond bonds 167 limit an amount of heat-transfer fluid within thefluid bladder 150. Limiting the amount of heat-transfer fluid within thefluid bladder 150 reduces a weight of thehead wrap 100 and improves comfort of the wearer. Furthermore, reducing an amount of heat-transfer fluid in thefluid bladder 150 prevents the head wrap 100 from assuming a rounded shape and losing contact with the wearer's scalp. - Still referring to
FIG. 1C , in various embodiments, athird layer 161 is positioned adjacent to thesecond layer 157. Thethird layer 161 includes a third-layer perimeter 163 that aligns with and is bonded to the first-layer perimeter 155 and the second-layer perimeter 159 so as to define acompression bladder 151 between thesecond layer 157 and thethird layer 161. Thefluid bladder 150 is positioned on a scalp-facing side of the head wrap 100 such that, in use, a wearer's scalp is in contact with, and thermally exposed to, thefluid bladder 150. The firstfluid port 134 and the secondfluid port 136 are fluidly coupled to the fluid bladder. The firstfluid port 134 facilitates delivery of a heat-transfer fluid to thefluid bladder 150 and the secondfluid port 136 facilitates removal of the heat-transfer fluid from thefluid bladder 150. Afirst barrier 152 is formed in thefluid bladder 150 generally parallel to the centralvertical axis 112. Thefirst barrier 152 separates the firstfluid port 134 from the secondfluid port 136. Acompression bladder 151 is formed in thehead wrap 100. Thecompression bladder 151 is disposed outwardly of thefluid bladder 150 and fluidly coupled to thecompression port 138. When a compressed gas is introduced to thecompression bladder 151, a downward force is imparted on thefluid bladder 150. Such downward force ensures intimate contact of thefluid bladder 150 with the wearer's scalp and prevents puckering of thefluid bladder 150. Such puckering can cause areas of the wearer's scalp to not be sufficiently thermally exposed to thefluid bladder 150 resulting in small areas of alopecia on the wearer's scalp. -
FIG. 1D is a cross sectional view of the illustrative head wrap 100 showing afourth layer 170 in accordance with one or more aspects of the disclosure. In various embodiments, thehead wrap 100 includes afourth layer 170 that is positioned outwardly of thethird layer 161. Thefourth layer 170 includes a fourth-layer perimeter 172 that is bonded to the third-layer perimeter 163 such that thecompression bladder 151 is defined between thethird layer 161 and thefourth layer 170. Additionally,third bonds 174 may be formed between thethird layer 161 and thefourth layer 170 at select locations so as to selectively position compression across the wearer's scalp. -

Athird securement tab 146 is disposed on thefirst arm 104 and afourth securement tab 148 is disposed on thecenter section 108. Thefluid bladder 150 is formed on a scalp-facing side of thehead wrap 100. Thefluid bladder 150 is fluidly coupled to the firstfluid port 134 and the secondfluid port 136. Afirst barrier 152 is formed in thefluid bladder 150 generally parallel to the centralvertical axis 112. Thefirst barrier 152 separates the firstfluid port 134 from the secondfluid port 136. Asecond barrier 154 is formed in thefluid bladder 150 generally parallel to the centralhorizontal axis 110 and generally perpendicular to thefirst barrier 152. Thesecond barrier 154 extends into, and directs flow of the heat-transfer fluid into, thefirst arm 104 and thesecond arm 106. Athird barrier 156, afourth barrier 158, afifth barrier 160, and asixth barrier 162 extend from thesecond barrier 154 into thefirst panel 114, thesecond panel 116, thethird panel 122, and thefourth panel 124, respectively. In use, thethird barrier 156, thefourth barrier 158, thefifth barrier 160, and thesixth barrier 162 direct the heat-transfer fluid into thefirst panel 114, thesecond panel 116, thethird panel 122, respectively. During operation, thefirst barrier 152, thesecond barrier 154, thethird barrier 156, thefourth barrier 158, thefifth barrier 160, and thesixth barrier 162 create a serpentine heat-transfer fluid flow path through thefluid bladder 150. The heat-transfer fluid flow path is illustrated byarrows 164; however, in other embodiments, the fluid flow could be in the direction opposite thearrows 164. -

FIG. 9 is a flow diagram illustrating aprocess 900 for applying theillustrative head wrap 100 in accordance with one or more aspects of the disclosure. Atblock 904, an interior aspect of thebody 102 is aligned with an occipital region the wearer's head. Atblock 906, thefirst arm 104 is coupled to thesecond arm 106 in the region of the wearer's forehead. Atblock 908, thefourth panel 124 is coupled to thefirst panel 114 and thethird panel 122 is coupled to thesecond panel 116. Atblock 910, thecenter section 108 is folded over a top of the wearer's head and coupled to at least one of thefirst arm 104 and thesecond arm 106 in the region of the wearer's forehead. In various embodiments, blocks 904-910 may be performed in any order. Atblock 912, thecap 702 is applied to the wearer's head to secure thehead wrap 100. Atblock 916, heat-transfer fluid is circulated through thefluid bladder 150. The heat-transfer fluid is introduced to thefluid bladder 150 via the firstfluid port 134 and the heat-transfer fluid is removed from the fluid bladder via the secondfluid port 136; however, in other embodiments the fluid flow may be reversed. The heat-transfer fluid removes heat from the wearer's scalp thereby cooling the wearer's scalp to a temperature below nominal scalp temperature. Such cooling has been shown to be effective in preventing the onset of alopecia in patients undergoing treatments such as, for example chemotherapy and radiation therapy. In other embodiments, the heat-transfer fluid can be circulated through thehead wrap 100 in order to add heat to the wearer's scalp thereby warming the wearer's scalp to a temperature above nominal scalp temperature. Such treatments can be useful in the treatment of, for example, migraines and strokes. At block 917, compressed gas is introduced to thecompression bladder 151 via thecompression port 138. The compressed gas inflates thecompression bladder 151 and imparts a downward force on thefluid bladder 150. Such downward force ensures intimate contact of thefluid bladder 150 with the wearer's scalp and prevents puckering of thefluid bladder 150. Such puckering can cause areas of the wearer's scalp to not be sufficiently thermally exposed to thefluid bladder 150 resulting in small areas of alopecia developing on the wearer's scalp. - Conditional language used herein, such as, among others, “can,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or states.
