  • Publication number: 20210386419
    Abstract: A positioning device for positioning an abnormal tissue is provided. The positioning device comprises a positioning tube and a positioning suture accommodated in the positioning tube. When the positioning suture is injected into the abnormal tissue, a head portion and a portion of a body portion of the positioning suture are retained inside the abnormal tissue while the rest of the body portion being exposed outside the abnormal tissue, thereby marking a specific area accordingly to facilitate the subsequent excision process.

  • Publication number: 20210199634
    Abstract: A rapid detection method of sulfide content is provided, which includes determining the concentration and volume of a metal ion solution, the volume of a sample, and the amount of a chemical reducing agent, depending on a threshold value. It also provides preparing the metal ion solution, sampling the sample, and mixing the metal ion solution with the sample to result in a mixture solution. The chemical reducing agent is added into the mixture solution to obtain the resulting solution. Naked-eye observation of the resulting solution is used to determine whether the sulfide content of the sample is over the threshold value. When the resulting solution is clear, this indicates that the sulfide content of the sample is greater than or equal to the threshold value. When the resulting solution contains precipitates, this indicates that the sulfide content of the sample is lower than the threshold value.
