  The present invention relates to a medical device having a function of preventing erroneous withdrawal of needles and a function of hemostasis in a long-time treatment operation using a puncture needle such as dialysis, blood transfusion, and drip. In particular, the present invention relates to a medical device having a function of preventing erroneous erroneous needle removal during dialysis treatment and a function of fixing a hemostatic material at the end of dialysis.

  In order to treat a disease, for example, hemodialysis treatment for the treatment of kidney disease, or a long-term treatment operation using a puncture needle such as blood transfusion or infusion may be performed. For example, in order to carry out hemodialysis, it is necessary to circulate blood outside the body. Therefore, at the start of dialysis treatment, two blood vessel indwelling needles are inserted to take out blood and return it to the body. At the start of dialysis treatment, it was necessary to fix the blood circuit near the vascular indwelling needle using a bandage or the like so that the vascular indwelling needle is not accidentally removed during dialysis treatment. At the end of dialysis treatment, the two blood vessel indwelling needles are withdrawn. However, the needle used for hemodialysis is larger in diameter than the needle used for normal injection, so immediately apply a hemostatic material to the puncture hole. In order to fix the hemostatic material, blood loss prevention measures such as winding a hemostatic belt are necessary.

  As described above, in hemodialysis treatment, not only blood loss prevention treatment is necessary at the end of dialysis treatment, but also indwelling needles and multiple places in the blood circuit must be fixed at the start of dialysis treatment, and further use There is a problem in that it requires complicated operations for hemodialysis treatment personnel, such as it is necessary to prepare and store a plurality of adhesive bandages in appropriate lengths before dialysis treatment. In addition, during dialysis treatment, there is a risk that the adhesive bandage with the indwelling needle or blood circuit fixed may be peeled off due to patient movement, and the needle may be accidentally pulled out. There was also a problem that there was.
