Abstract

A medical garment for use with a helmet, wherein the garment comprises a shell and a transparent face shield configured to define a barrier between the wearer and the environment. The transparent face shield may comprise a tab configured to be at least partially disposed within an alignment channel of the helmet when the medical garment is attached to the helmet to orient the shell relative to the helmet. The tab may also be separate from the transparent face shield and disposed on the shell of the medical garment. The transparent face shield may also comprise an attachment element configured to removably couple with a coupling member of the helmet, wherein the attachment element and coupling member comprise complementary coupling surfaces.

First claim

What is claimed is:

1. A surgical apparel system including a peripheral device, said surgical apparel system comprising:
a surgical helmet to be worn over the head of a wearer, said surgical helmet comprising a face frame, said face frame comprising:
a face frame having a distal surface and defining a recess in said distal surface;
a first coupling member disposed within said recess and having a distal surface positioned proximal to said distal surface of said face frame, said first coupling member comprising one of a ferromagnetic material or a magnetic material;

a surgical garment configured to be at least partially disposed over said surgical helmet to provide a microbial barrier between a medical environment and the wearer, said surgical garment comprising:
a transparent face shield;
a first attachment element comprising the other of the ferromagnetic material or the magnetic material, said first attachment element comprising a head having a proximal surface, said head configured to removably engage said first coupling member when said surgical garment is at least partially disposed over said surgical helmet; and
wherein said proximal surface of said head is positioned at least partially within the recess of said face frame when said first attachment element engages said first coupling member.

2. The surgical apparel system of claim 1 , wherein said surgical helmet further comprises a sensor disposed within said face frame and positioned to detect when said first attachment element of said surgical garment is coupled to said surgical helmet by detecting the presence of said first attachment element adjacent to said first coupling member.

3. The surgical apparel system of claim 2 , wherein said first coupling member comprises a magnetic material and said first attachment element comprises a ferromagnetic material; and
wherein said sensor is a Hall-Effect sensor configured to detect changes in the magnetic field surrounding said first coupling member based, at least in part, on the proximity of said first attachment element to said first coupling member.

4. The surgical apparel system of claim 2 , wherein said first coupling member comprises a ferromagnetic material and said first attachment element comprises a magnetic material; and
wherein said sensor is a Hall-Effect sensor configured to detect changes in the magnetic field surrounding said first coupling member based, at least in part, on the proximity of said first attachment element to said first coupling member.

5. The surgical apparel system of claim 1 , wherein said face frame comprises a chin bar, and said first coupling member is disposed within a recess defined in said chin bar such that said distal surface of said first coupling member is positioned proximal to a distal surface of said chin bar.

6. The surgical apparel system of claim 5 , wherein said surgical helmet further comprises a sensor positioned adjacent said first coupling member; and
wherein said sensor is configured to detect when said first attachment element of said surgical garment is coupled to said surgical helmet by detecting the presence of said first attachment element adjacent to said first coupling member.

7. The surgical apparel system of claim 1 , wherein said proximal surface of said first attachment element defines a coupling recess on a wearer side of said microbial barrier and is configured to removably engage said first coupling member on said surgical helmet, said coupling recess shaped to resist decoupling of said surgical garment from the surgical helmet in response to a lateral force being applied to said surgical garment.

8. The surgical apparel system of claim 1 , wherein said first attachment element further comprises a coupling recess formed in said proximal surface of said head and is configured to engage said first coupling member; and
wherein said coupling recess of said first attachment element is positioned proximal to said distal surface of said face frame when said first attachment element engages said first coupling member.

9. The surgical apparel system of claim 8 , wherein said coupling recess defines a coupling surface that opens toward said proximal surface of said head, said coupling surface having a concave shape.

10. The surgical apparel system of claim 1 , wherein said transparent face shield comprises an upper portion, a lower portion, a first surface and an opposing second surface.

11. The surgical apparel system of claim 10 , further comprising a first aperture defined in said upper portion of said face shield;
wherein said surgical helmet further comprises a top beam comprising an alignment channel; and
wherein said top beam further comprises a protrusion at least partially disposed in said alignment channel, said protrusion configured to engage said first aperture in said upper portion of said face shield.

12. The surgical apparel system of claim 11 , wherein said transparent face shield further comprises a tab extending from said upper portion of said transparent face shield, said tab comprising opposing outer edges;
wherein said first aperture of said transparent face shield is at least partially defined within said tab; and
wherein said tab is configured to be at least partially disposed within said alignment channel when said first aperture engages said protrusion.

13. The surgical apparel system of claim 10 , wherein said head of said first attachment element further comprises a distal surface opposite said proximal surface and a post extending distally from said distal surface of said head.

14. The surgical apparel system of claim 13 , wherein said post of said first attachment element further comprises a proximal portion and a distal portion;
wherein said proximal portion has a first dimension and said distal portion has a second dimension, said post configured such that said first dimension is greater than said second dimension;
wherein said transparent face shield further comprises a second aperture in said lower portion; and
wherein said distal portion of said post of said first attachment element is at least partially disposed in said second aperture and said proximal portion abuts said transparent face shield to space said distal surface of said head from said first surface of said transparent face shield.

15. The surgical apparel system of claim 1 , wherein said surgical helmet comprises a second coupling member disposed within a second recess in said distal surface of said face frame and comprising the ferromagnetic material or the magnetic material of said first coupling member;
wherein said surgical garment comprises a second attachment element comprising the other of the ferromagnetic material or the magnetic material of said first attachment element; and
wherein said second attachment element is configured to removably engage said second coupling member when said surgical garment is at least partially disposed over said surgical helmet such that a proximal surface of a head of said second coupling member is positioned proximal to said distal surface of said face frame when said second attachment element engages said second coupling member.
