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.
Claim 11
Dependent Claim 25 words
A method according to claim 8, wherein said connecting step includes connecting each of said multiple inlet ports to a supply source of forced air.
Claim 12
Dependent Claim 36 words
A method according to claim 9, 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 13
Dependent Claim 25 words
A method according to claim 9, further including the step of providing a single supply source for connection to each of said multiple inlet ports.
Claim 14
Dependent Claim 43 words
A method according to claim 11, 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 15
Independent Claim 86 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 are hook and loop fastener strips; 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 16
Independent Claim 86 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 are hook and loop fastener strips; 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 17
Dependent Claim 32 words
A method according to claim 8, 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 18
Dependent Claim 25 words
A method according to claim 14, wherein said connecting step includes connecting each of said multiple inlet ports to a supply source of forced air.
Claim 19
Dependent Claim 36 words
A method according to claim 15, 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 20
