Abstract
Abstract An article to be used as an aid in the treatment of epistaxis consisting of a fluid absorbing portion which is pear shaped in cross-section for insertion into a part of the nasal cavity with a semi-rigid handle portion having along one end section a multi-spoked support structure about which the fluid absorbing portion is mounted and maintained in the pear shaped cross section. When inserted into the nasal cavity the pear shaped cross section of the fluid absorbing portion, as maintained by the support structure, provides both essentially uniform pressure for constricting blood flow and localities for aggregation of fibrin to promote blood clotting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
An epistaxis treatment device comprising a stem means, a fluid absorbing pad means affixed to one end of said stem means, and a handle means disposed at the other end of said stem means for inserting into and removing from a nasal cavity said pad means; said fluid absorbing pad means having a substantially pear shaped outer cross-section, the height of said pear shaped cross-section being about twice the maximum width thereof, and the axis of said maximum width being positioned at a location vertically spaced from the middle of the height axis; said stem means including an integral support system means which maintains the pear shaped cross-section of the pad means; whereby insertion of said pear shaped fluid absorbing pad in a nasal cavity facilitates absorption of fluid and applies pressure on the traumatized mucosa of the nasal cavity.
Claim 2
Dependent Claim
140 words
An epistaxis treatment device comprising a stem means, a fluid absorbing pad means affixed to one end of said stem means, and a handle means disposed at the other end of said stem means for inserting into and removing from a nasal cavity said pad means; said fluid absorbing pad means having a substantially pear shaped outer cross-section, the height of said pear shaped cross-section being about twice the maximum width thereof, and the axis of said maximum width being positioned at a location vertically spaced from the middle of the height axis; said stem means including an integral support system means which maintains the pear shaped cross-section of the pad means; whereby insertion of said pear shaped fluid absorbing pad in a nasal cavity facilitates absorption of fluid and applies pressure on the traumatized mucosa of the nasal cavity.
Claim 3
Dependent Claim
79 words
The epistaxis treatment device as set forth in claim 1 in which said fluid absorbing pad means is affixed to said support system means, and said stem means extends beyond the end of said fluid absorbing pad means a sufficient distance to be capable of being grasped for positioning and inserting said fluid absorbing pad means in a nasal cavity thereby providing for ease of insertion of said fluid absorbing pad into the nasal cavity and subsequent removal therefrom.
Claim 4
Dependent Claim
47 words
The epistaxis treatment device as set forth in claim 1 in which a core of absorbent cotton is mounted about said support system means, and said core of absorbent cotton is surrounded by at least one layer of cotton gauze to form said fluid absorbent pad means.
Claim 5
Dependent Claim
46 words
The epistaxis treatment device as set forth in claim 1 in which said fluid absorbing means is formed from materials capable of resiliently expanding when fluid is absorbed, thereby increasing the pressure applied by said fluid absorbing pad to the nasal mucosa as fluid is absorbed.
Claim 6
Dependent Claim
52 words
The epistaxis treatment device as set forth in claim 1 in which said support system means includes four secondary stems which branch from said stem means and extend longitudinally along the length of said stem means, said secondary stems being supported along their length by spoke elements extending from said stem means.
Claim 7
Independent Claim
107 words
A method of treating epixtaxis comprising the steps of: (i) inserting into a nasal cavity an epistaxis treatment device comprising a stem means, a fluid absorbing pad means affixed to one end of said stem means, and a handle means disposed at the other end of said stem means; said fluid absorbing pad means having a substantially pear shaped outer cross-section; said stem means including an integral support system means which maintains the pear shaped cross-section of the pad means; (ii) permitting coagulation to occur; and, (iii) removing said fluid absorbing pad by grasping said handle means and withdrawing said fluid absorbing pad from said nasal cavity.
Claim 8
Independent Claim
107 words
A method of treating epixtaxis comprising the steps of: (i) inserting into a nasal cavity an epistaxis treatment device comprising a stem means, a fluid absorbing pad means affixed to one end of said stem means, and a handle means disposed at the other end of said stem means; said fluid absorbing pad means having a substantially pear shaped outer cross-section; said stem means including an integral support system means which maintains the pear shaped cross-section of the pad means; (ii) permitting coagulation to occur; and, (iii) removing said fluid absorbing pad by grasping said handle means and withdrawing said fluid absorbing pad from said nasal cavity.
Claim 9
Dependent Claim
25 words
The method of treating epistaxis as set forth in claim 6 in which medicaments are introduced into the nasal cavity by said fluid absorbing pad.
