Rapid warmer for blood and blood products
First Claim
1. A unitary device for warming or defrosting products for injection or perfusion, particularly blood products, contained in hermetically sealed bottles or bags, comprising:
- an upwardly opened cell for receiving at least one bottle or bag of product;
means for filling up and obtaining a continuous circulation of water in said cell comprising an inlet line and an overflow outlet line for the water; and
means for controlling the temperature and the flow rate of the water in said cell,said controlling means comprising an adjustable thermostatic tap connectable on the one hand to a cold water distribution network and on the other hand to a hot water distribution network, and an adjustable flow control valve, said adjustable thermostatic tap and said adjustable flow control valve being fitted in said inlet line of the water circulating means,said overflow outlet line forming an overflow for draining the water and having an inlet provided at an upper part of said cell,the outlet of said temperature controll water inlet line opening into a lower part of said cell adjacent a first lateral side of said cell, the inlet of said overflow outlet line being located adjacent a second lateral side of said cell opposite said first lateral side,whereby at least one bottle or bag of product introduced into said cell is submergable by temperature controlled water continuously circulating around the at least one bag or bottle.

8. A process for warming or defrosting products for injection or perfusion, particularly blood products, contained in hermetically sealed bottles or bags, comprising the steps of:
-
filling up and continuously circulating water in an upwardly opened cell by water circulating means comprising an inlet line and an overflow outlet line; controlling the temperature and the flow rate of the water by means of an adjustable thermostatic tap connectable on the one hand to a cold water distribution network and on the other hand to a hot water distribution network, and an adjustable flow control valve, said adjustable thermostatic tap and said adjustable flow control valve being fitted in said inlet line of the water circulating means, said overflow outlet line forming an overflow for draining the water and having an inlet provided at an upper part of said cell, the outlet of said temperature controlled water inlet line opening into a lower part of said cell adjacent a first lateral side of said cell, the inlet of said overflow outlet line being located adjacent a second lateral side of said cell opposite said first side; introducing at least one bottle or bag of product into said cell such that said at least one bottle or bag of product is submerged by the temperature controlled water continuously circulating around the at least one bottle or bag; and removing the at least one bottle or bag of product from the cell when the product contained therein is warmed or defrosted. - View Dependent Claims (9, 10, 11)

12. A unitary device for warming or defrosting products for injection or perfusion, particularly blood products, contained in hermetically sealed bottles or bags, comprising:
-
an upwardly opened cell for receiving at least one bottle or bag of products; means for filling up and obtaining a continuous circulation of water in said cell so that said at least one bottle or bag of product placed in the cell is submerged and the water circulates around said at least one bottle or bag; means for controlling the temperature and the flow rate of the water in said cell; an indicator for indicating the characteristics of the products introduced into the said cell; and means capable of receiving a specification card of a patient for whom the products are intended. - View Dependent Claims (13, 14, 15, 16)
