The present invention relates to a hemostatic device capable of performing a quick and safe hemostasis to a puncture site where tissue is collected after renal tissue examination.

Kidney tissues must be collected for accurate diagnosis, treatment selection, and prognosis of patients with kidney disease.

The kidney tissue extracted from the kidney was fixed with formalin solution, wrapped with paraffin, thinly sliced, and specially stained and examined under a microscope to diagnose a treatment method.

As such, retrieval of kidney tissue, which had to be collected for accurate diagnosis, treatment selection, and prognosis of a patient with kidney disease, causes local anesthesia at the puncture site.

After that, while the patient stops breathing for a while, the biopsy needle is inserted into the kidney through the puncture site, and the tissue is collected with the biopsy needle.

After retrieval of kidney tissue, the biopsy needle was removed, and the bleeding was confirmed by ultrasound.

In the process of hemostasis after renal tissue collection, it depends on the characteristics of the patient. Usually, when the puncture site is pressed for 10 minutes or more, hemostasis is frequently performed.

If hemostasis is prolonged after renal biopsy, a lot of discomforts occur in activity, so hemostasis is maintained by using a separate hemostatic band.

In particular, when the hemostatic band used to maintain the hemostasis state for a long time to the chest was inclined toward the waist from the shoulder portion, it was required to prevent the hemostatic band to be worn down to the waist side.

The present invention aims to stably pressurize the puncture portion of the chest from which kidney tissue is collected after renal biopsy to stably stop hemostasis.

In addition, the present invention has a feeling that there is no feeling of pressure on the chest area in the worn state to cover the entire chest so that only the puncture site where the kidney tissues are collected can be locally pressed to make the hemostasis efficient. .

The pressing unit 100, the opening hole 120 perforated to expose the abdomen when the chest is wrapped around the front of the weaving stand 110 is made of a stretchable cotton material, and the weave of the weave stand 110 Both ends overlap with each other in the back portion is preferably provided with a mounting member 140 that is engaged with each other to maintain a worn state.

That is, when the weave 110 is formed of a stretched fabric and wraps the weave 110 in the chest, the weave 110 is elastically pressed to the chest and forms a form in which the skin of the chest is pressed.

The weave 110 is of sufficient length to surround the chest, and both ends of the weave 110 surrounding the chest overlap at the back of the chest.

By the mounting member 140 installed in the overlapping portion, the weaving stand 110 is maintained in a state wrapped around the chest.

Since the mounting member 140 is required to have mutual coupling force on the overlapping surface, a zipper, a magnet, a hawk, a snap button, and a magic tape, which are generally used, may be applied.

In addition, in the process of wrapping the chest with the weave 110, the opening hole 120 formed in the front of the weave 110 forms a state that the navel of the chest and its peripheral position is not pressed.

This is to ensure that there is no pressure on the abdomen to the patient wearing the weave 110.

The thorax on which the weave 110 is worn is physically in the shape of an inverted triangle or gourd from the shoulder position to the waist, so that the worn weave 110 can move down to the navel area due to the movement of the body structure. Therefore, a configuration to prevent this is required.

Therefore, a configuration for preventing the weave 110 from flowing down in a state surrounding the chest in the hemostatic device according to the renal biopsy is required.

Accordingly, the framing unit 200 is made of a thin rod material having elasticity to maintain the form surrounding the upper side of the chest and the first frame 210, and maintain the form surrounding the lower chest and the first frame 210.
