Abstract

Disclosed is a portable hemodialyzer, which not only can relieve a patient from the pain of putting injection needles into two portions of the patient'"'"'s body for hemodialysis, but also enables the hemodialysis to be safely performed even at home, so as to reduce the times by which the patient must visit the hospital, thereby largely reducing time and expense. In the portable hemodialyzer, an injection needle contains a separation film separating an introduction channel and a discharge channel from each other, which are formed in the injection needle. A blood exit is formed at a predetermined left side portion of the injection needle, while a blood entrance is formed at a predetermined right side portion of the injection needle. Therefore, the blood introduced through the blood entrance by the pumping operation by the driving force of the driving section is delivered through the introduction channel to the hemodialysis filter, filtered by the hemodialysis filter, and then supplied through the discharge channel and the blood exit to the blood vessel.

Claims

1. A portable hemodialyzer comprising:

an injection needle containing a separation film separating an introduction channel and a discharge channel from each other, which are formed in the injection needle;

medical tubes connected with the injection needle, so as to transport blood;

a hemodialysis filter filtering the blood supplied through the medical tubes, the blood being discharged from the hemodialysis filter after being filtered;

a sensor section disposed at one side portion of the hemodialysis filter and generating predetermined electric signals according to flowing velocities of the blood;

a driving section generating driving force which enables the blood to be hemodialyzed by the hemodialysis filter; and

a control section controlling the driving section, the control section stopping the driving section when the sensor section generates a predetermined electric signal.

2. A portable hemodialyzer as claimed in claim 1, wherein the separation film in the injection needle separates the introduction channel and the discharge channel from each other, and the injection needle has a blood entrance formed at a predetermined portion of the introduction channel, a blood exit formed at a predetermined portion of the discharge channel, a needle end formed at a lower end of the injection needle, and a connecting portion formed at an upper end of the injection needle, the blood being introduced through the blood entrance into the injection needle and discharged through the blood exit out of the injection needle, the needle end having a pointed shape which enables the injection needle to be easily put into a blood vessel, the needle end being closed so as to prevent the blood from flowing into and out of the injection needle through the needle end, the connecting portion having jaws which prevent the medical tubes from being easily separated from the connecting portion when the medical tubes are detachably assembled with the connecting portion.
