Description

Technical Field

[0001] The utility model relates to the field of compression hemostasis, in particular to an automatic compression hemostasis tool which can be used for both arterial puncture and other venous punctures. Background Art

[0002] Venipuncture and arterial puncture are common nursing procedures, performed daily by responsible nurses. In the ICUs of large, top-tier hospitals, these procedures alone can reach thousands of venous and arterial blood draws per month, representing a significant portion of the nurses' workload. Manual compression is typically performed after drawing blood or removing the needle from a patient. Venipunctures typically take 3-5 minutes, while arterial punctures can take 5-15 minutes. This can be extended for patients with poor coagulation function.

[0003] The intensive care unit is a self-service ward. After blood is drawn or needles are removed from patients, nurses are generally required to perform manual compressions. Most blood draws in the intensive care unit are from arteries, and the preferred site for arterial blood draws is the radial artery. Arterial compressions take a long time and require a significant amount of nurse time. However, patients in intensive care units are generally in serious condition, and nurses are busy. Sometimes, due to emergency treatment or the need for other urgent operations, the compression time cannot meet the requirements, resulting in local bleeding, subcutaneous hematoma, or bruising, causing harm to the patient. Therefore, there is an urgent need for an automatic compression hemostatic patch to replace manual compressions, ensuring the compression time after puncture and needle removal for patients while also reducing the workload of nurses.

[0004] In the prior art, there are also some hemostatic tools that achieve automatic compression through inflation. However, the pressing part of existing hemostatic tools is basically designed as an inflatable airbag. To ensure the quality of the compression, the airbag covers a large area. During the inflation process, the airbag presses a relatively large area. Existing hemostatic tools can be used normally for hemostasis during ordinary venous blood collection. However, for arterial blood collection, mainly arterial blood collection from the radial artery, existing hemostatic tools have significant drawbacks. Those skilled in the artery are aware that the radial artery is located at the wrist, and the ulnar artery is located adjacent to the radial artery. The ulnar artery and the radial artery are relatively close. Generally, when pressing the radial artery, it is necessary to ensure that the ulnar artery has a good blood supply to avoid affecting the blood supply to the extremities. In addition, the wristband of existing compression hemostasis tools is fixed to the compression component, so the size of the wristband is specific. However, in addition to the wrist, the blood puncture sites also include the arm, ankle and thigh. Different sites require wristbands of different lengths. If the wristband is set longer, it will not be very convenient to use when targeting thinner sites such as the wrist. If the wristband is set shorter, it cannot be used on multiple sites. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing technology and to propose an automatic pressing hemostasis tool. The hemostasis tool is mainly used for arterial puncture hemostasis of the radial artery. During the hemostasis process, it will not affect the normal blood supply of the ulnar artery. Moreover, the hemostasis tool can be used for puncture hemostasis of multiple parts of different thicknesses such as the wrist, arm, and leg, thereby reducing the workload of nurses.
