Abstract
A phlebotomy aid provides a capability to expand circulatory members for emphasizing venous appearance and accessibility on an epidermal surface. A warming sheath or sleeve extends over a patient forearm for introducing a thermal source adjacent to a patient blood vessel for emphasizing the vein appearance on the epidermal surface. A beating element in the sleeve is powered and controlled by a low voltage circuit for controlled thermal introduction for mitigating discomfort from overheating and eliminating proximity of potentially harmful electrical exposure.
Claims20
A medical device, comprising:
- a flexible, planar heating medium adapted for encircling an appendage for heat transfer, the planar heating medium forming a sleeve defining an interior volume;
- a textile base;
- the planar heating medium including a linear thermal element adhered to the textile base, the linear thermal element responsive to electricity for heat generation across the textile base,
- the linear thermal element traversing a path across the textile base, the path defining a heating zone based on an expected location of a vein in the appendage;
- the linear thermal element disposed at a distance in the heating zone for focusing heat on the expected location of the vein, the heating zone, the heating zone including a longitudinal center along at least one panel of the textile base and the heating zone generating greater heat than the planar heating medium outside the heating zone;
- an opening in the sleeve for receiving an appendage into the interior volume for warming;
- and
- an electrical source for energizing the heating medium for warming the interior volume.

A phlebotomy aid system, comprising:
- an elongated flexible sleeve having an opening, the flexible sleeve defined by a textile base and having a receptacle adapted for receiving a human forearm;
- a liner having a size based on an interior of the receptacle for insertion thereof;
- a linear thermal element attached to the sleeve for heating the receptacle, the linear thermal element adhered to the textile base, the linear thermal element responsive to electricity for heat generation across the textile base;
- the linear thermal element traversing a path across the textile base, the path defining a heating zone based on an expected location of a vein in the appendage;
- the linear thermal element disposed at a distance in the heating zone for focusing heat on the expected location of the vein, the heating zone, the heating zone including a longitudinal center along at least one panel of the textile base and the heating zone generating greater heat than the planar heating medium outside the heating zone;
- and
- a power supply connected to the thermal element for energizing the thermal element.
