Description
- The present disclosure relates generally to garment support systems and more particularly body mounted apparatus to support protective apparel.
- Protective apparel may be worn by surgeons and other care givers or other medical personnel in order to protect patients from infection. Orthopedic procedures and particularly those involving exposed bone are very susceptible to infection and osteomyelitis. Therefore protective apparel may be used to create a sterile field, typically achieved by a gown, often referred to as a "toga" that provides a barrier between the healthcare professionals and the patient.
- In some cases, helmets may be worn on the head of the surgical staff supporting the protective apparel. The helmets however can be heavy and can result in a high center of gravity as they extend upwards from the head, resulting in discomfort and an un-ergonomic fit. This can lead to undue neck and back strain on the surgeon. Further, a face shield and an apparel drape can add weight and drag to a helmet. Protective apparel including a helmet, face shield, and apparel drape often restricting movement of the wearer's head due to the added weight and drag.
- Further, the face shield may result in a limited field of vision. Additionally, as a result of the contours and nature of the helmet alignment above the head, the face shield may sit close to the wearer's face and may create an uncomfortable and claustrophobic feel. Face shield size may be limited by the outer contours of the helmet. Extending portions of the face shield and/or protective apparel that hang off of the helmet may cause further drag and undue strain.
- Some solutions incorporate a chin bar on the helmet that couples to portions of the apparel; however this may further limit the field of vision of the surgeon, and may add more weight to the helmet. Typically patients are positioned below the surgeon's head and may be positioned such that the chin bar obstructs the surgeon's view of the patient.
- The protective apparel may enclose the wearer's head and may trap in air exhausted by the wearer. Fans have been incorporated into the helmet and positioned on top of the user's head, and may add even more weight to the helmet further exacerbating the weight and center of gravity issues described above. The fan may draw air in through the gown material and may result in increased current drain on the fan. This may result in reduced battery life or an increased size of the power source to effectively transport air into the interior space of the protective suit.
- In some cases the power source must be carried off-helmet in order to incorporate enough energy to power the fan. In such case, a cable may run from the helmet to the power source, typically on a belt, and may restricting the wearer's movement, may rub against the wearer and/or may become unplugged during a procedure, such as a surgery. These fans may further prevent effective air circulation as they may merely force air into the enclosed area around the wearer's head.
- Further, donning procedures may be important in maintaining the sterile field about the wearer. Current helmet systems may be cumbersome and may include unnecessary steps to don the system while maintaining sterility.

Figures 27-29 and the accompanying description. Other embodiments and features described in the application, but not consistent with the claims, are presented not as embodiments of the invention but as background art or examples useful for understanding the invention. - Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of apparatus components for a protective apparel and support system. Accordingly, the apparatus components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
- In describing the embodiments herein in detail and referring to the drawings, like numbers indicate like parts throughout the figures. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of "a," "an," and "the" includes plural reference, the meaning of "in" includes "in" and "on." Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. While some embodiments described herein reference a user or wearer, specifically a surgeon, embodiments of a protective apparel and support apparatus can be used by any user and/or wearer, for example, surgeons and/or other doctors, scientists, students, or any other user that can use protective apparel. In this manner, while some embodiments described herein can reference a patient, in other embodiments, the wearer may be working on, for example, an experiment, a hazardous material, or any other object and/or situation that may prefer protective apparel. Some embodiments described herein provide a protective apparel and support apparatus that provides a number of advantages, including but not limited to a more comfortable fit by offering a lower center of gravity, improved ergonomic design, a wider stance for improved field of vision, and an effective energy efficient airflow system. In such embodiment, the protective apparel and support apparatus ("apparatus") can be supported off of the head of a user. In such embodiments a contoured yoke support structure ("yoke") can rest upon the torso of a user, for example portions of the waist, back, shoulders and chest of a user.
- In embodiments, of the invention, the yoke of the protective apparel support apparatus can be substantially free from contact with the wearer's head. The yoke support structure can include a frame that can be shaped to fit a user's shoulders and shaped to carry and support portions of the protective apparel. The frame can carry portions of the protective apparel which may include a transparent vision shield (e.g., a face shield or shield), barrier material such as a gown, interior air replenishment devices (e.g. a fan), and can distribute the weight of the protective apparel and support apparatus about the torso of the wearer. This can provide the wearer with a comfortable, protective apparel and support apparatus that has a low center of gravity, that may not rest on the wearer's, head and that may provide an ergonomic support to improve wearability.
- In some embodiments, the yoke can include a first support portion that can be configured to rest at least partially on a first shoulder of a wearer and a second support portion that can be configured to rest at least partially on a second shoulder of the wearer. Protective apparel can be coupled to the first support portion and the second support portion of the yoke support structure, and can be configured to include a vision shield in front of the wearer's face for viewing and a protective barrier over the wearer.
- In some embodiments, an air circulation system can be configured to be coupled to the yoke, and can be configured to provide air replenishment and air conditioning. The air circulation system can include a first fan and a second fan. The first fan can be configured to draw air into or out of the interior of a barrier space and the second fan can be configured to draw air into or out of an interior barrier space. The first fan and the second fan can be disposed away from the wearer's ears and can reduce noise generated by the fans. The yoke can include one or more hollow chambers configured to communicate air within the yoke. In some embodiments, the first fan and the second fan can be disposed within, or coupled to a yoke support structure portion that can extend down the back of the wearer. In some embodiments, a single fan may be used to draw air out of the interior barrier space or to introduce outside air into the interior barrier space.
- In some embodiments, an intake fan can be configured to direct air through a yoke portion and out of a front of the yoke in a direction substantially parallel to the wearer's vision, which in some embodiments can be toward the vision shield. This can reduce an amount of air blown directly onto the wearer's face. In such an embodiment, the air may be directed around a curvature of the vision shield in front of the wear's face and to another side of the yoke. One or more inlet ports on the other side of the yoke can be directed to an exhaust fan that can create negative pressure that can result in drawing the air out of the interior of the barrier space.
- In some embodiments, the vision shield has a surface area, i.e. a field of vision, of at least 464.52 cm2 (72 inches square) and preferably one to four times greater than 464.52 cm2 (72 inches square). A lateral distance between the first yoke portion and the second yoke portion provides for a greater field of vision as the vision shield spans from the first yoke portion to the second yoke portion while the first yoke portion and the second yoke portion are supported by the wearer's shoulders.
- In other embodiments, the support apparatus couples to a harness including a waist belt and shoulder straps. The waist belt and shoulder straps may be stand alone or incorporate into wearable garments. In other embodiment, the support apparatus coupled to a torso securement device such as a jacket, vest, a shirt, etc.

An apparatus can include a yoke, one or more gowns, togas, and/or hoods (single piece and/or multi-piece), and/or a harness, etc. While each embodiment can be described as including certain element or features, it is understood that non-mutually exclusive elements and features of any embodiment can be included in any other embodiment. -
FIG. 1 depicts a yoke support structure ("yoke") 100 of a protective apparel and support apparatus according to an embodiment. Theyoke 100 is a support structure that can be configured to rest on the shoulders and upper torso region of a wearer (not shown inFIG. 1 ). Theyoke 100 includes afirst chest member 102a, asecond chest member 102b and alateral chest member 102c. Theyoke 100 further includes afirst back member 106a coupled to thefirst chest member 102a, and asecond back member 106b coupled to thesecond chest member 102b. Theyoke 100 can be configured such that theinner contours 120a, b of theyoke 100 can substantially rest on the shoulders of the wearer and can substantially rest adjacent to portions of the chest and back of the wearer. The yoke 100can be configured to rest securely on the upper torso of the wearer and can be configured to support portions of the protective apparel (not shown). Thefirst chest member 102a and thefirst back member 106a form thefirst shoulder portion 104a. Thesecond chest member 102b and thesecond back member 106b form thesecond shoulder portion 104b. - In this embodiment the
first back member 106a is hingedly coupled to thefirst chest member 102a with afirst hinge 108a; and thesecond back member 106b is hingedly coupled to thesecond chest member 102b with asecond hinge 108b. Thefirst hinge 108a and thesecond hinge 108b can allow theyoke 100 to adjust to the size of the wearer by pivoting the chest member and the back member relative to one another about hinges 108a, 108b, to change the shoulder opening size ofyoke 100. This can accommodate difference in torso thickness from one wearer to another wearer while still allowing theyoke 100 to wrap over the shoulders. In alternative embodiments, theyoke 100 is a unitary structure and may be flexible such that yoke material bends, and can allow the yoke to be "form-fit" to the wearer by bending the unitary structure. Other embodiments may incorporate a plurality of members, while some or all may be flexible or some or all may be at least semi-rigid, or a combination thereof. For example, a portion of the yoke may be a formable wire frame and another portion may be a plastic support portion. - The
yoke 100 can be configured to rest on the wearer's shoulder at thefirst shoulder portion 104a and at thesecond shoulder portion 104b. In this embodiment thechest members lateral chest member 102c. In other thechest members second chest members yoke 100 can also partially rest on the chest in varying degrees with thechest members 102a-c. -
FIG. 2 is a side view of ayoke 100 shown positioned on awearer 200. Theyoke 100 is positioned on thewearer 200's shoulders and include a substantiallytransparent vision shield 202 positioned in front of thewearer 200'sface 204. Thevision shield 202 can be configured to maintain barrier protection of the protective apparel while allowing thewearer 200 to see the patient. The weight of thevision shield 202 can be supported by theyoke 100 and can be distributed onto the shoulders 206 and can transfer the weight of thevision shield 202 to the wearer. Thevision shield 202 position relative to the wearer'sface 204 can be a function of a standoff distance (not shown) of thevision shield 202 from thechest members 102a-c and anangle 208 of a tilt away from theyoke 100 and the wearer. Having thevision shield 202 coupled to theyoke 100 can offset the vision shield 202 a distance from the wearer's face. - The
first back member 106a and thesecond back member 106b can act as counter weight configured to counteract a moment of force on the front of theyoke 100 due to the weight of thevision shield 202, a protective garment 302 (see, e.g.,FIG. 3 ), and the front portion of theyoke 100. Balancing theyoke 100 minimizes movement of theyoke 100 relative to thewearer 200. A length and a weight of theback members front chest member 102a-c. While some of the force on the front of theyoke 100 can be imparted from the chest member's 102a-c on to the wearer's chest, the counter weight effect of theback members yoke 100 can cradle the wearer's torso to minimize movement of theyoke 100 as it is worn. - As shown in
FIGS. 1-4 , theyoke 100 can include a downward u-shape that can lower the center of gravity of the overall protective apparel and support apparatus (not shown) as it sits over the shoulders of the wearer, distributing the weight to stabilize the apparatus. Although it is preferred that movement of the protective apparel and support apparatus is minimized, some movement of the apparatus relative to the wearer may be acceptable. In such embodiments, thevision shield 202 can be sized such that some movement does not hinder the wearer's line of sight. -
FIG. 3 is a side view of theyoke 100 shown positioned on awearer 200 and includes thevision shield 202 and aprotective garment 302. Theprotective garment 302 can be coupled to theyoke 100, thevision shield 202 and/or a combination thereof. In this embodiment theprotective garment 302 is coupled to thevision shield 202. Thevision shield 202 can be selectively coupled to the yoke and can be coupled to the yoke after the yoke is fitted on the wearer. In other embodiments, thevision shield 202 can be coupled to the yoke prior to the yoke being fitted to the wearer. Theprotective garment 302 can be, for example, a hood, a body toga, a gown, an upper torso gown, combinations of said protective garments, and/or the like. Theprotective garment 302 is positioned between the patient and the surgeon or care giver. Theprotective garment 302 and thevision shield 202 can be configured to form aninterior barrier space 314. Theinterior barrier space 314 is generally the space between theprotective garment 302 and the wearer. The wearer's head and at least portions of the upper body of the wearer are contained within theinterior barrier space 314. Theinterior barrier space 314 is separated from anexterior 316 of the system. -
FIG. 4 is a side view of theyoke 100 as it rests on the wearer's torso, showing the conforming fit of theyoke 100 to the wearer's upper torso according to another embodiment. Theback members 106a-b rest on aback portion 402 of the wearer's torso, theshoulder portions 104a-b, rest at least on the top of the wearer's shoulders and thechest members 102a-c rest on a front portion of the wearer's shoulders and the chest of the wearer's torso.

FIG. 13 , the internal air ports 1306 a-e are located in achest member top 130a ofyoke 100. This position in theyoke 100 allows the air to be directed parallel to the wearer's line of sight and not onto the wearer directly. The air flow is directed along thevision shield 202, beginning where thevision shield 202 meets theyoke 100 at a yoke-shield interface line 1340. The air flow generally travels along theshield 202 until the shield curves around to mate with the second chest member 102b. Said another way, the shield can include a curvilinear shape; can extend from a first side ofyoke 100 to a second side ofyoke 100; and can curve around achest portion 102a-c. The air can be diverted by thevision shield 202 and can generally travel around theshield 202 and can be directed toward the opposite side of thevision shield 202 and thesecond chest member 102b. In this embodiment, the air can travel from one of internal air ports 1306 a-e on a first side of theyoke 100 to an internal air port (not shown) on a second side of theyoke 100. - The quantity of internal air ports may be fewer than or greater than those illustrated in the present embodiment. The size of the apertures may also vary, and may further vary from port to port. The air can flow to the internal air ports 1306 a-e via one or more internal chambers, or internal chamber portions of the yoke100. The internal chamber comprises the
first chamber 532 of thechest member 102a which is in communication with thesecond chamber 536 of theback member 106a of theyoke 100. Thehinge portion 1330 of thechest member 102a and theback member 106a, is configured to couple thechest member 102a and theback member 106 a such that the air can move between thechest member 102a and the back member 106, and the internal air ports and external air ports. As shown inFIG. 13 ,yoke 100 can include a blower (e.g. a fan) 1318.Blower 1318 can be disposed within theback member 106a and can be adjacent to theexternal air port 510. In this embodiment theblower 1318 can draw air into the yoke chamber, thesecond chamber 536, which then travels through thehinge 1330 to thefirst chamber 532 and out theinternal air ports 1306a-e. - In this embodiment outlet ports 520 (see
FIG. 5 ) have a similar arrangement, as with thefirst chest member 102a of the yoke portions illustrated inFIG. 13 , in thesecond chest member 102b. A second blower can be disposed in theback member 106b however; the second blower can be configured to draw air out of theinterior barrier space 514 throughoutlet ports 520, a first and second chamber of thesecond chest member 102b, through the second blower and out the secondexternal port 512. - Also illustrated in
