The device has a protection cap (1) defining a concavity, and a thin sharp-ended tubular stem (15) joined to the cap and projecting into its concavity; the tubular stem (15) is connected to means (7, 9) for penetration into the human body or into body liquid containers; the device is suitable for use in combination with sample tubes (8) to be inserted into the concavity in the cap (11) and having their interior chamber under vacuum and closed by a yieldable elastomeric plug (8) able to seal the laceration produced by the tubular stem. The tubular stem (15) is joined at one end to the interior concavity of the cap (11), and is constructed of synthetic resin in one piece with the cap (11). <IMAGE> |
