| Abstract
|
| [Objective] The compound needle-type oxygen sensor was improved in the part of reference electrode and test equipment. Its performance was tested and then used to monitor the oxygen partial pressure in vivo. [Methods] A stainless syringe was used as the reference electrode. The indicating electrode was ripped into the needle to construct the compound needle-type oxygen sensor together with the stalk of the acupuncture needle. The intelligent four-channel oxygen tester was further developed through coupling with the computer. The intelligent data processing was achieved. The oxygen pressure was monitored in the stomach acupoints in rabbit with experimental stomach-trauma. [Results] The improved compound oxygen sensor can successfully real-time monitor the oxygen partial pressure of deep tissue in vivo continually, in a fixed point with minimal trauma, and set the sensor and treatment in one procedure. The measurement in vivo showed the existence of the specific changes of oxygen pressure in the stomach Shuxue in rabbit with experimental stomach-trauma. [Conclusions] The improved compound oxygen sensor can successfully finish a real-time monitoring of partial oxygen in deep tissue in vivo continually, in a fixed point with minimal trauma. |
