Abstract

An installation for delivering calories to all or part of human or animal cell tissue via a liquid comprises: a heating unit heating the liquid; an injection unit injecting the liquid into the heating unit; a dispenser for dispensing the heated liquid; and a transporter for transporting the liquid from the heating unit to the dispenser. The installation allows the heated liquid to be dispensed from the dispensing means in a pulsed operation.

Claims (21)

1. An installation for delivering heat to all or part of human or animal cell tissue by means of a liquid, said installation comprising:

a heating unit for heating said liquid,

an injection unit for injecting liquid into the heating unit,

a means for diffusion of the heated liquid,

a means for conveying the heated liquid from the heating unit to the diffusion means,

means for delivering the heated liquid at the diffusion means in a pulsed operation;

wherein the heating unit is separated from the conveying means by a valve calibrated to a pressure at least equal to a saturation vapor pressure of the liquid to be injected.

2. The installation as claimed in claim 1 , wherein the heating unit is in the form of a metal coil incorporating an electrical resistor or a heat exchanger around which there is wound a stainless steel tube whose internal diameter is between 0.1 and 0.5 mm, a length of the tube varying between 1500 and 5000 mm.

3. The installation as claimed in claim 1 , further comprising a cold water branch circuit having a point of departure positioned between the injection unit and the heating unit, and a point of arrival positioned downstream of the valve, said branch circuit being connected at the point of departure by means of a programmable high-pressure solenoid valve.

4. The installation as claimed in claim 1 , wherein the conveying means is in the form of a hollow tube with an internal diameter of between 50 and 150 μm, and a length of the tube being between 40 and 80 cm.

5. The installation as claimed in claim 1 , wherein the diffusion means is in the form of a hollow tube whose distal end is closed off and whose walls are provided in whole or in part with substantially circular apertures having a diameter of between 30 and 70 μm, an external diameter of the tube being between 100 and 250 μm, while an internal diameter is between 50 and 150 μm.

6. The installation as claimed in claim 1 , wherein the diffusion means is in the form of a rigid needle whose distal end is closed off and whose walls have, along all or part of their length, apertures with a diameter of between 30 and 70 μm, an internal diameter of the needle being between 0.05 and 0.2 mm, while an external diameter is between 0.2 mm and 0.7 mm, length being between 100 and 200 mm.

7. The installation of claim 6 , wherein said substantially circular apertures have a diameter of 50 μm.

8. An installation for delivering heat to all or part of human or animal cell tissue by means of a liquid, said installation comprising:

a heating unit for heating said liquid,

an injection unit for injecting said liquid into the heating unit,

a means for diffusion of heated liquid,

a means for conveying the heated liquid from the heating unit to the diffusion means,

means for delivering the heated liquid at the diffusion means in a pulsed operation;

wherein the injection unit injects the liquid into the heating unit at a pressure greater by at least 50 bar, advantageously 100 bar, than the saturation vapor pressure of said liquid to be injected; and

wherein the heating unit is separated from the conveying means by a valve calibrated to a pressure at least equal to a saturation vapor pressure of the liquid to be injected.
