Hemostasis device used after medical puncture

Abstract

The invention discloses a hemostasis device used after medical puncture. The hemostasis device comprises a first hemostasis mechanism and a second hemostasis mechanism, and the first hemostasis mechanism comprises a hemostasis bag and a filling injection pipe, wherein the hemostasis bag has a predetermined shape after filling injection, and the filling injection pipe communicates with the hemostasis bag; the second hemostasis mechanism comprises an external sleeve and a piece of hemostasis sponge, and the hemostasis sponge is arranged in the external sleeve and located at the axial end of theexternal sleeve; and the external sleeve is separably arranged outside the filling injection pipe in a sleeving mode, and the hemostasis bag not subjected to filling injection and the filling injection pipe are suitable for penetrating through the hemostasis sponge. The hemostasis bag in the first hemostasis mechanism is located at the puncture position, then the hemostasis sponge in the second hemostasis mechanism is utilized to enable the hemostasis bag to guide the hemostasis sponge to be located at the puncture position, the hemostasis sponge makes contact with a vascular wall by pulling the external sleeve, after blood makes contact with the hemostasis sponge, the hemostasis sponge adheres to the vascular wall, and thus hemostasis is achieved. The hemostasis process is relatively simple and convenient, and a puncture mouth can be subjected to hemostasis effectively and quickly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemostatic device for medical puncture. Background technique [0002] In the field of medical technology, interventional examination and treatment of blood vessel punctures have been widely used. For example, use a vascular sheath to puncture a blood vessel to draw blood and secretions in the blood vessel for laboratory tests; or use a vascular sheath to puncture a blood vessel and inject a contrast agent into the blood vessel for contrast examination; or, implant a stent into the artery through the vascular sheath To support the blood vessel wall, maintain the normal flow of blood. [0003] However, after the above-mentioned inspection or treatment is finished, the vascular sheath needs to be withdrawn. After the vascular sheath is withdrawn, a large puncture hole will be formed on the vessel wall, resulting in the outflow of fresh blood. Especially after the art...

Problems solved by technology

[0003] However, after the above-mentioned inspection or treatment is completed, the vascular sheath needs to be withdrawn. After the vascular sheath is withdrawn, a large puncture hole will be formed on the vessel wall, resulting in the outflow of fresh blood.

Especially after the puncture of the artery, due to the high blood pressure, the blood will flow out quickly, making it difficult to effectively stop the bleeding
