Description
Technical field
The present invention relates to a kind of calibrating installations of Medical Instruments, more specifically, it relates to a kind of pneumoperitoneum apparatus calibrating installation.
Background technique
It needs to establish operative space in abdominal cavity when laparoscopic surgery, this just needs (to be commonly used for CO2 to Peritoneal Infusions gas
Gas), stomach wall is raised before making, in order to have the good visual field and operated with instrument.
Pneumoperitoneum apparatus is to establish and maintain the indispensable equipment of pneumoperitoneum.There are two types of its driving methods: pneumatic and electric drive.
1. air-flow is continuously conveyed in old-fashioned pneumatic type pneumoperitoneum apparatus, stop supplying gas after Intra- abdominal pressure reaches predetermined pressure.Pneumatic type gas
Abdomen machine generally up to flow velocity is only 4L/min, and there are two pressure to select knob: pressure and high flow capacity being maintained to supply gas.Intra- abdominal pressure and
The gas pressure in the bottle is controlled by analog form.When carrying out complicated laparoscopic surgery, gas flow will at least reach 6L/min.And
Pneumatic type pneumoperitoneum apparatus is only capable of reaching 4L/min, therefore is not suitable for complicated operation and uses.2. the flow velocity of supplying gas of electronic type pneumoperitoneum apparatus is long-range
In pneumatic type, peak flow rate (PFR) is up to 30L/min.Pressure selection is continuously adjustable.Number with intra-abdominal pressure, flow velocity and air inflow
Display.Most electronic type pneumoperitoneum apparatus working conditions divide two-phase: change on gas and test period.When change on gas, gas is sent through connecting conduit
People abdominal cavity；Pressure measurement is carried out after supplying gas immediately.Some pneumoperitoneum apparatus use two connection hoses, and one is used to supply gas, another
For measuring intra-abdominal pressure.There are also a kind of pneumoperitoneum apparatus can be sucked back the gas seen off through filter with another pump, from
And it is recycled.The gas recycled in this way be it is constant, can effectively eliminate black smoke when using coagulation instrument.Using following again
When ring pumps pneumoperitoneum apparatus, sensor continuously monitors the pressure and perfusion pressure for returning to gas.
It is needed when laparoscopic surgery using multiple casings, gas can be through overflowing around casing or its.Must be discharged in time makes
The smog caused by electric coagulating apparatus tool or laser burn.But also intraperitoneal blood and liquid to be sucked out in time, therefore best
Using the pneumoperitoneum apparatus of l0L/min or more flow, effectively to maintain Intra- abdominal pressure when carrying out aforesaid operations.Sometimes suction is being used
When drawing with peritoneal lavage, it is also necessary to which higher flow velocity is just able to satisfy the needs of operation.When gas being perfused under so high flow velocity,
Gas is desirable to by heating, humidifying or preferably recycling.Because excessive cold air can reduce the temperature of peritonaeum, cause obvious
Temperature decline.No matter any laparoscopic surgery, pneumoperitoneum apparatus must the operation is stable.Although most pneumoperitoneum apparatus can automatically control
Intra- abdominal pressure, but should often pay attention to the display of inspection apparatus, understand intraperitoneal actual pressure.Operation consent have to be understood that gas
Whether abdomen machine is working properly and carries out necessary calibration.
Currently, national Various Hospitalss pneumoperitoneum apparatus quantity it is very huge, since country is without corresponding pneumoperitoneum
Machine calibrating standard or vertification regulation, cause a large amount of hospitals pneumoperitoneum apparatus lose supervision, independently declared by equipment supplier completely
Claim its performance indicator whether up to standard or simple test verifying is carried out by the medical professionals department of hospital.Once pneumoperitoneum apparatus output pressure
It is out of control, the life security of patient will be threatened, and insufficient pressure or pressure instability then will lead to operative space deficiency, extend hand
The art time reduces surgical quality, increases operation risk.
Device according to the present invention can carry out the calibration of precise quantification, it is ensured that hospital is with pneumoperitoneum apparatus to pneumoperitoneum apparatus
Quality be controlled.The type approval that simultaneously can be used for pneumoperitoneum apparatus and the verifying after maintenance.
Summary of the invention
