## Abstract

This is a device, belonging to the medical and hospital artifacts industry, developed to accelerate the hemostatic process for patients undergoing radial punctures, partially compressing the artery subjected to treatment; said cryo-hemostatic device is essentially presented in the form of a wristband (1), providing end bands (2) providing velcro-based closing, interconnected by an intermediate band (3) below which a first cryogenic reservoir pad is located (4), which can be filled with a saline substance by the action of a syringe connected to the first connection nipple (5) attached to the first tube (6), flanked by the second external reservoir pad (7), also provided with a second connection nipple (8), attached to the second tube (9).

## Claims

### Claim 1

A compressive cryo-hemostatic device comprising:
a wristband (1) with end bands (2) provided with Velcro on opposite ends operable to secure the device around a wrist of a user;
an intermediate band (3) provided between the end bands (2);
a first cryogenic reservoir pad (4) configured to be filled with a saline substance through a syringe via a first connection nipple (5) attached to a first tube (6), wherein the syringe is configured to be operably connected to the first connection nipple (5); and
a second external reservoir pad (7) provided with a second connection nipple (8) attached to a second tube (9), wherein,
the first cryogenic reservoir pad (4) is disposed adjacent to the second external reservoir pad (7);
the first cryogenic reservoir pad (4) is isolated from the second external reservoir pad (7);
one end of the intermediate band (3) is connected to a portion between the first cryogenic reservoir pad (4) and the second external reservoir pad (7), and another end of the intermediate band (3) is connected to at least one of the end bands (2) such that the first cryogenic reservoir pad (4) is configured to be disposed below the intermediate band (3) thereby being exposed to the wrist of the user when the device is secured to the wrist of the user; and
the second external reservoir pad (7) is disposed over at least a portion of the end bands (2) such that the second external reservoir pad (7) remain unexposed to the wrist of the user when the device is secured to the wrist of the user.
