Before measurement: by this device as horizontal table top, regulate the second three-way cock 7, will be with ambient atmosphere phase
Logical extraneous port 9 is connected (measurement port 8 is closed) with abdominal cavity connecting tube 4；Regulate the one or three to open up
Closing 3, with water column, abdominal cavity connecting tube 4 is measured pipe 1 and is connected, now water column is measured pipe 1 two ends and is borrowed the external world
Perforate 10 above port 9 and right side all communicates (mercury column is measured pipe 2 and closed) with ambient atmosphere, by noting
Water/osculum 16 injects recommended dose test distilled water, makes water column measure the VERTICAL TUBE on both sides in pipe 1 and goes out
Liquid high for the most about 4-5cm is put down, and the rule 12 of regulation water column measurement pipe 1 makes its liquid put down and is classified as 0cm.
During measurement: regulate the second three-way cock 7, measurement port 8 is connected with abdominal cavity connecting tube 4 (outer
Boundary's port 9 is closed), the measurement port 8 with abdominal paracentesis syringe needle is inserted laboratory animal abdominal cavity, according to
Animal abdominal pressure during experiment, the liquid of water column measurement pipe 1 is flat to change, as intraperitoneal is malleation, then
Left side intraluminal fluid is flat to be declined, and the right intraluminal fluid is flat to be risen, and puts down upper floating colour according to the right intraluminal fluid and floats
Mark 14, with reference to the scale made zero before, records reading.Left side pipe liquid is put down the height of decline and is added the right pipe liquid
Put down the height risen, or pipe read scale in the right is multiplied by 2, is laboratory animal intra-abdominal pressure numerical value this moment.
Part II: mercury column measures (unit: millimetres of mercury, mmHg)
Before measurement: by this device as horizontal table top, regulate the second three-way cock 7, will be with ambient atmosphere phase
Logical extraneous port 9 is connected (measurement port 8 is closed) with abdominal cavity connecting tube 4；Regulate the one or three to open up
Close 3, abdominal cavity connecting tube 4 measured pipe 2 with mercury column and is connected, open closing flap valve 13 by means of universal driving shaft,
There is the liquid flat (less than closing flap valve 13) of about 20mm on the both sides making mercury column measure pipe 2, and now mercury column is surveyed
Buret 2 two ends borrow the perforate 10 above measurement port 8 and the right pipe all to communicate with ambient atmosphere, regulate hydrargyrum
Rule 12 on post measurement pipe 2 makes its liquid put down and is classified as 0mm.
During measurement: regulate the second three-way cock 7, measurement port 8 is connected with abdominal cavity connecting tube 4 (outer
Boundary's port 9 is closed), the measurement port 8 with abdominal paracentesis syringe needle is inserted laboratory animal abdominal cavity, according to
Animal abdominal pressure during experiment, the liquid of mercury column measurement pipe 2 is flat to change, as intraperitoneal is malleation, then
Left side intraluminal fluid is flat to be declined, and the right intraluminal fluid is flat to be risen.Liquid according to the right pipe is put down, with reference to making zero before
Scale, record reading.Left side pipe liquid is put down the height of decline and is added the right pipe liquid and put down the height of rising, or right
Pipe read scale in limit is multiplied by 2, is laboratory animal intra-abdominal pressure numerical value this moment.
Part III: digital pressure gauge measures (unit: kPa, kPa)
Before measurement: by this device as horizontal table top, regulate the second three-way cock 7, will be with ambient atmosphere phase
Logical extraneous port 9 is connected (measurement port 8 is closed) with abdominal cavity connecting tube 4；Regulate the one or three to open up
Close 3, abdominal cavity connecting tube 4 is connected with intelligent digital Pressure gauge 6 by pressure transducer 5, calibration,
Zero piezometer.
During measurement: regulate the second three-way cock 7, measurement port 8 is connected with abdominal cavity connecting tube 4, will
Measurement port 8 with abdominal paracentesis syringe needle inserts laboratory animal abdominal cavity, according to animal abdominal cavity pressure during experiment
Power, by built-in pressure transducer 5, shows the electronic curtain at intelligent digital Pressure gauge 6 by force value
On, directly carry out reading.
Because along with the breathing of laboratory animal, abdominal pressure reaction is put down slight fluctuation up and down at liquid, is surveyed
During amount, unification is as the criterion according to scale during laboratory animal end-tidal.
Laboratory animal abdominal pressure of the present utility model detection device has been filled up and has been lacked at present for abdomen inner high voltage
Animal model is verified, the blank of metering outfit, and the concrete operations setting up animal model according to laboratory are started with,
Use engineering technology principle, three kinds of internationally recognized pressure measurement modes are merged, integrate, manifold
Road, multi-method verifies simultaneously, and metric results is directly perceived, is not required to by formula scales, and pressure limit on probation is wide.
This device instrument is small and exquisite, light, and required consumptive material is conventional, the most simple to operate, safely, quickly, it is possible to
It is widely used in zoopery detection.
This utility model above description is section Example, but this utility model is not limited to above-mentioned
Detailed description of the invention.Above-mentioned detailed description of the invention is schematic, is not restrictive.Every
Use structure of the present utility model, without departing from this utility model objective and scope of the claimed protection
In the case of, within all concrete expansions all belong to protection domain of the present utility model.
