Abstract
Abstract The present invention relates to a method for warming a patient with a blanket used with forced air convection systems, wherein the blanket includes multiple inlet ports. By providing a blanket with multiple inlets, the user has the choice of positioning the air supply or blower unit and the supply hose on either side of the patient. In addition, in a preferred embodiment, the inlet ports are resealable, thus allowing the user to switch inlets during use.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
90 words
A method of preventing hypothermia, said method comprising: providing a blanket which may be used with a forced air convection system, wherein such blanket includes multiple inlet ports and wherein said multiple inlet ports are initially sealed closed; providing means to open said multiple inlet ports, wherein said means to open comprises a tear strip; placing said blanket over or under a patient; connecting at least one of said multiple inlet ports to a supply source of forced air; and supplying forced air from said supply source to said blanket.
Claim 2
Independent Claim
90 words
A method of preventing hypothermia, said method comprising: providing a blanket which may be used with a forced air convection system, wherein such blanket includes multiple inlet ports and wherein said multiple inlet ports are initially sealed closed; providing means to open said multiple inlet ports, wherein said means to open comprises a tear strip; placing said blanket over or under a patient; connecting at least one of said multiple inlet ports to a supply source of forced air; and supplying forced air from said supply source to said blanket.
Claim 3
Dependent Claim
25 words
A method according to claim 1, wherein said connecting step includes connecting each of said multiple inlet ports to a supply source of forced air.
Claim 4
Dependent Claim
36 words
A method according to claim 2, further including the step of providing a separate supply source for each of said multiple inlet ports, and connecting a separate supply source to each of said multiple inlet ports.
Claim 5
Dependent Claim
25 words
A method according to claim 2, further including the step of providing a single supply source for connection to each of said multiple inlet ports.
Claim 6
Dependent Claim
43 words
A method according to claim 4, wherein said blanket includes two inlet ports, and further including the step of providing a supply hose having a Y-shaped configuration and connecting one arm of said Y-shaped supply hose to each of said inlet ports respectively.
Claim 7
Dependent Claim
32 words
A method according to claim 1, further including the step of selectively choosing one of said multiple inlet ports for connection to said supply source based on surgical or medical procedure criteria.
Claim 8
Dependent Claim
13 words
A method according to claim 1, wherein said blanket includes two inlet ports.
Claim 9
Independent Claim
101 words
A method of preventing hypothermia, said method comprising: providing a blanket which may be used with a forced air convection system, wherein such blanket includes multiple inlet ports and wherein said multiple inlet ports are sealed with reversible sealing means; wherein said reversible sealing means is selected from the group consisting of an adhesive strip, double-sided tape, snaps, zippers, folding flaps, and a ziplock type seal; placing said blanket over or under a patient; connecting at least one of said multiple inlet ports to a supply source of forced air; and supplying forced air from said supply source to said blanket.
Claim 10
Independent Claim
101 words
A method of preventing hypothermia, said method comprising: providing a blanket which may be used with a forced air convection system, wherein such blanket includes multiple inlet ports and wherein said multiple inlet ports are sealed with reversible sealing means; wherein said reversible sealing means is selected from the group consisting of an adhesive strip, double-sided tape, snaps, zippers, folding flaps, and a ziplock type seal; placing said blanket over or under a patient; connecting at least one of said multiple inlet ports to a supply source of forced air; and supplying forced air from said supply source to said blanket.
