Injection and hemostasis site
First Claim
1. A method of suppressing bleeding at tissue needle site which comprises:
- pressing a soft pad against the skin of a patient, said soft pad being clear for direct visualization of a bleeding site underneath the pad without having to remove the pad, said pad consisting essentially of an elastomer having a hardness of no more than about durometer 30 Shore 0;
passing a medical needle through the pad into the tissue of the patient; and
thereafter withdrawing said needle, whereby bleeding is suppressed by contact of the soft pad against the tissue needle site.

Abstract
A pad of elastomeric material having a softness of no more than about durometer 30 Shore 00. The pad may carry adhesive for adhering the pad to a surface, either directly or indirectly through an envelope which surrounds the pad and carries the adhesive. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.

- pressing a soft pad against the skin of a patient, said soft pad being clear for direct visualization of a bleeding site underneath the pad without having to remove the pad, said pad consisting essentially of an elastomer having a hardness of no more than about durometer 30 Shore 0;
- 17. A soft and non-absorbent pad of elastomeric material having a hardness of no more than about durometer 30 Shore 0, said soft pad being clear for direct visualization of a bleeding site underneath the pad without having to remove the pad, said pad carrying an adhesive or a strap member for securing the pad with a surface surrounding the bleeding site, the pad being configured to be pressed against the bleeding site, whereby bleeding or leakage through the skin of a patient or a wall of a hollow medical device is stopped by contact of the pad with the bleeding site.

32. A method of suppressing bleeding from a bleeding site from the skin of a patient, which comprises:
- providing a clear, soft and non-absorbent pad of elastomeric material having a hardness, less than about durometer 30 Shore 0; and
suppressing said bleeding, including applying in firm contact with the bleeding site of the patient the clear, soft pad whereby said clear, soft pad permits direct visualization of the bleeding site underneath the pad without having to remove the pad. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
- providing a clear, soft and non-absorbent pad of elastomeric material having a hardness, less than about durometer 30 Shore 0; and
- 49. A soft, clear and non-absorbent pad for hemostasis of elastomeric material having a hardness of no more than about durometer 30 Shore 0, said pad being configured to be pressed against a wound or cannulation site, whereby bleeding or leakage through the skin of a patient is stopped due to contact of the pad with the wound or cannulation site, and whereby the wound or cannulation site can be directly visualized through the pad without having to remove the pad.
