Abstract
A cold therapy system includes a cooling bath; a therapy pad; a heat exchanger; a first pathway fluidly connecting the cooling bath to the heat exchanger; a second pathway fluidly connecting the heat exchanger to an inlet of the therapy pad; a third pathway fluidly connecting an outlet of the therapy pad to the heat exchanger; and a fourth pathway fluidly connecting an outlet of the heat exchanger to the cooling bath.
Claims24
A cold therapy system comprising:
- a cooling bath;
- a therapy pad;
- a heat exchanger;
- a first pathway fluidly connecting the cooling bath to the heat exchanger;
- a second pathway fluidly connecting the heat exchanger to an inlet of the therapy pad;
- a third pathway fluidly connecting an outlet of the therapy pad to the heat exchanger;
- and
- a fourth pathway fluidly connecting an outlet of the heat exchanger to the cooling bath, wherein the first, second, third and fourth pathways are fluidly connected to the heat exchanger such that chilled fluid from the cooling bath receives heat from warmed fluid returning from the therapy pad.
5 more elements
A cold therapy system comprising:
- a cooling bath;
- a therapy pad;
- a heat exchanger positioned and arranged to exchange heat acquired from fluid exiting the therapy pad with fluid exiting the cooling bath;
- a sleeve extending between the heat exchanger and the therapy pad;
- a first pathway fluidly connecting an outlet of the heat exchanger to an inlet of the therapy pad;
- and
- a second pathway fluidly connecting an outlet of the therapy pad to an inlet of the heat exchanger, wherein the first and second fluid pathways are located within the sleeve.
4 more elements
A cold therapy system comprising:
- a cooling bath including a housing for storing a cooling fluid;
- a therapy pad for placement on a user to cool the user;
- and
- a heat exchanger for exchanging heat acquired from a user with cooling fluid flowing from the cooling bath to the therapy pad, the heat exchanger carried by a wall of the housing of the cooling bath.
1 more element
A cold therapy unit method comprising:
- (i) chilling water;
- (ii) flowing the chilled water to absorb heat from warmed water returning from a therapy pad,
- (iii) flowing the heat-absorbed chilled water through the therapy pad becoming warmed water,
- (iv) flowing the warmed water to deliver heat to incoming chilled water, and
- (v) flowing the heat delivering warmed water to be re-chilled.
