Description

A kind of electrochemical therapeutical instrument

Technical field

This utility model relates to a kind of electrochemical therapeutical instrument, relates in particular to a kind of multi-channel portable electrochemical therapeutical instrument that is used to treat tumor.

Background technology

The electrochemical therapeutical instrument majority of using at present is the single channel electrochemical therapeutical instrument; The defective of giving prominence to below it exists: 1) diameter of tumor is greater than more than the 2cm; Treatment needs for a long time, the patient needed 8 hours to 16 hours and misery unbearably, the doctor also is unwilling to accept this method.

2) oncotherapy is incomplete, still have after the treatment a large amount of cancerous cell remaining, recovery Qu Cuncun arranged, be prone to recurrence.Treatment only at anode pH less than 4, negative electrode pH could kill cancer cells greater than 10, pH cancerous cell between 4 to 10 in its mesozone is prone to recovery makes treatment not exclusively.

3) when voltage surpassed 10 volts, the patient felt pain, was prone to take place inhomogeneous, the sudden cardiac arrest accident of mass transfer.

4) surpass 10 volts when voltage, the electric current density increase, electrode effusion energy is many, and useful effect is in the cancerous cell little energy, and clinical therapeutic efficacy is bad.

Although a lot of doctors have thought a lot of methods, cut apart therapy like employing, lump is divided into several parts; Each treatment is a part of, do not treat the method for a lump simultaneously fully, but cancerous cell increases rapidly; Make and cut apart therapy and be difficult to cure the monoblock tumor, the patient also can't connect and hold.

Summary of the invention

Problems such as this utility model has designed a kind of electrochemical therapeutical instrument, and it has solved treatment time length, the treatment gross tumor volume is limited, and clinical treatment is dangerous.

In order to solve the technical problem of above-mentioned existence, this utility model has adopted following scheme:
