The procuratorate intervened in advance in the case of Zhejiang doctors who violated regulations and caused many people to get infected with AIDS.
Reporters learned today from the Supreme People's Procuratorate, Zhejiang, Shandong, two prosecution has bloodstream infections in patients are caused by medical procedures accident involved in the investigation of two cases of advance the cause of social concern currently violation, guiding investigation and evidence collection. In February 2017, Zhao, a technician in Zhejiang Provincial Hospital of Traditional Chinese Medicine in Hangzhou, Zhejiang Province, did not strictly implement the operating procedures, resulting in iatrogenic HIV infection. On February 8, the Shangcheng District Public Security Bureau of Hangzhou City investigated Zhao. It is ascertained that Zhao violated the “one person, one tube, one abandonment†operation procedure, repeated use of straws in the operation to cause cross-contamination, resulting in patients infected with HIV, and 5 cases were diagnosed and infected. After the case occurred, the Shangcheng District Procuratorate intervened in the case in advance and sent personnel to participate in the task force meeting to guide the investigation and evidence collection. Currently, the case is under investigation. On January 16, 2017, a patient who was dialysis in the negative area of ​​the dialysis room in the People's Hospital of Chengyang District, Qingdao City, Shandong Province, was diagnosed with hepatitis B virus antigen by hepatitis B virus markers. Hepatitis B core antibody is positive. After the People's Hospital of Houchengyang District transferred Jinmou into the dialysis room positive area for dialysis, six other patients who were dialysis in the hospital were infected six times, and eight new hepatitis B surface antigen-positive patients were newly discovered. According to a preliminary investigation by the health department, this was a serious infection caused by violation of the operating procedures in the hemodialysis room of the hospital. After the incident, the Shandong Provincial Procuratorate initiated the rapid response mechanism for major sensitive incidents, guided the Qingdao Municipal Procuratorate to investigate and verify the relevant situation, and guided the public security organs to conduct preliminary investigations.
The piston is one of the main moving parts of the
engine, is composed of combustion chamber components. Engine Piston Parts,Engine Parts ,Car Engine Parts,Parts Of Engine,Piston Engine Parts ZhouShan HeCheng Machinery Co., LTD. , https://www.hcmarineparts.com
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
