Electrode holder, headwear, and wire jacket adapted for use in sleep apnea testing
An electrode holder is adapted for cooperating with a strap applied to a body part of a patient to hold a surface electrode to the skin. The electrode holder includes a base and a post projecting from the base. The post is adapted for extending through the strap and into a cavity formed with the electrode. The electrode holder is releasably attached to the strap by mating hook and loop fasteners. Once attached, the post of the holder secures the electrode in position thereby reducing motion artifacts caused by disturbance of the electrode after placement against the skin of the patient.
1. An electrode holder adapted for cooperating with a strap applied to a body part of a patient to hold a surface electrode to the skin, said electrode holder comprising:
(a) a base;
(b) a post projecting from said base, and adapted for extending through the strap and into a cavity formed with the electrode, said post comprising a reinforcing member formed with said base and having a generally X-shaped cross-section; and
(c) means for attaching said electrode holder to the strap, whereby said post secures said electrode in position thereby reducing motion artifacts caused by disturbance of said electrode after placement against the skin of the patient.
2. An electrode holder according to claim 1 , wherein said post further comprises an electrode-penetrating tip extending from said reinforcing member.
3. An electrode holder according to claim 2 , wherein said electrode-penetrating tip has a rounded end to facilitate entry into the cavity of the electrode.
4. An electrode holder according to claim 1 , wherein said base comprises a thin flat disk.
5. An electrode holder according to claim 1 , wherein said means for attaching comprises hook fasteners located on said base and adapted for releasably mating with complementary loop fasteners located on the strap.
6. An electrode holder according to claim 1 , wherein said base and said post are integrally formed together of a molded polymer.
7. An electrode holder according to claim 6 , wherein said polymer comprises ABS plastic.
8. In combination with a strap adapted for being applied to a body part of a patient, an electrode holder cooperating with said strap to hold a surface electrode to the skin, said electrode holder comprising:
(a) a base;
(b) a post projecting from said base, and extending through said strap for insertion into a cavity formed with the electrode; and
(c) hook fasteners located on said base and adapted for releasably mating with complementary loop fasteners located on the strap, whereby said post secures said electrode in position thereby reducing motion artifacts caused by disturbance of said electrode after placement against the skin of the patient.
9. A combination holder according to claim 8 , wherein said post comprises a reinforcing member formed with said base.
10. A combination according to claim 9 , wherein said reinforcing member has a generally x-shaped cross-section.
11. A combination according to claim 10 , wherein said post further comprises an electrode-penetrating tip extending from said reinforcing member.
12. A combination according to claim 11 , wherein said electrode-penetrating tip has a rounded end to facilitate entry into the cavity of the electrode.
13. A combination according to claim 8 , wherein said base comprises a thin flat disk.
14. A combination according to claim 8 , wherein said base and said post are integrally formed together of a molded polymer.
15. A combination according to claim 14 , wherein said polymer comprises ABS plastic.
16. A combination according to claim 8 , wherein said strap defines a post-receiving slit accommodating passage of said post through said strap and into the cavity of the electrode.
