Embodiment Construction

[0024] In the prior art, manual pressing is usually used for hemostasis of the punctured blood vessel. Medical staff use fingers to press blood vessels to achieve compression and hemostasis. Generally, it needs to press for 10-15 minutes, and then use gauze pads and bandages to pressurize and bandage. However, this method has high requirements for medical personnel, and it is difficult to control the pressing force, and it is also easy to cause bleeding or hematoma.

[0025] In addition, in the prior art, a femoral artery suturer is used to suture the blood vessel to achieve hemostasis, specifically, the puncture point is sutured through minimally invasive surgery. However, this method has high requirements on blood vessels, and if the vessel wall is diseased or hardened, it cannot be sutured. And, this equipment is expensive, increases patient operation cost. Therefore, it is urgent to propose a new hemostasis method to stop bleeding of blood vessels after surgical 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...
