Description
Technical field
The present invention relates to the technical fields of animal physiological, more particularly, to a kind of measurement milk cow pulmonary artery and right ventricular pressure
Device and method.
Background technology
Tibet region is that traditional herding sparetime university of China saves.Recently as carrying for economic development and living standards of the people
Height, Tibet Autonomous Region increase the demand of dairy products and beef year by year.Yak adapts to High aititude low-oxygen environment, for a long time with
Become the main source of high altitude localities resident's milk and beef, but the production cycle of yak is longer and meat productivity is low, makes
The high Holstein cow of the output of milk, which must be introduced, becomes solution milk supply main path in short supply.Holstein cow is originating from Holland, with it
The feature that the output of milk is high, milk-quality is good cultivates most milk cows as the whole world.High aititude low-oxygen environment is for holstein cow
It is a huge physiology challenge, is to lead to milk cow in regional due to hypoxemia caused by pulmonary hypertension of the height above sea level higher than 2000 meters
The main reason for dead.The kinds such as holstein cow, Jersey, the Angus beef of Qinghai-Tibet Platean cultivation have generation altitude sickness
Report, especially with the incidence highest of Tibet region.Tibet Autonomous Region once repeatedly from interior ground Introduced Holstein Dairy Cow, but with
Milk cow death rate caused by altitude sickness is too high and fails.In recent years, Tibet Autonomous Region plans to introduce 10 between 2017-2022
Ten thousand cow heads are cultivated to Tibet region, but altitude sickness causes the milk cow death of higher proportion in the introducing process of early stage,
Therefore milk cow altitude sickness becomes the main reason for hindering Tibet region or even high altitude localities milk cattle cultivating industry development.
Holstein cow altitude sickness is a kind of pulmonary edema of the idiopathic under environment of low oxygen plateau, causes pulmonary artery by hypoxemia
High pressure and right heart failure lead to the disease of milk cow death.Report within 1915 that ox altitude sickness is happened at height above sea level and is higher than 1524 meters for the first time
Colorado, main feature show as right heart failure caused by pulmonary hypertension and chest oedema.Altitude sickness is height above sea level
2000 meters or more areas cause the highest disease of the ox death rate, and Chinese Qinghai-Tibet mean sea level is at 4000 meters or more, Lhasa
City's height above sea level transports the holstein cow to high altitude localities at 3658 meters, therefore from plains region, and the incidence of altitude sickness exists
60% or more, the death rate accounts for the 40% of full group.There are no effectively preventing measures for altitude sickness so far, can only find disease as early as possible
Ox simultaneously sells to reduce economic loss, or morbidity ox is transported to low altitude area and waits for its own recovery, to High aititude
The milk cattle cultivating industry development in area causes huge economic loss, and still, there are no the effective heart, lung are dynamic on milk cow at present
Pulse pressure force measuring method.

Push floating catheter that floating catheter is made to enter right ventricle, it is to be seen to arrive the right heart to floating catheter injecting heparin sodium solution
Floating catheter air bag is played after chamber pressure signature waveform；
Floating catheter inwardly is continued to press on, when floating catheter enters pulmonary artery and stable pulmonary artery signature waveform occurs, into
Row repeatedly measures, and records mean pulmonary arterial pressure.
8. the method according to claim 7 for measuring milk cow pulmonary artery and right ventricular pressure, which is characterized in that described inside
Floating catheter is continued to press on, when floating catheter enters pulmonary artery and stable pulmonary artery signature waveform occurs, records pulmonary artery
In the step of mean pressure, pressure measurement repeats 3-5 times, measures 20-30 complete waveforms every time, records mean pulmonary arterial pressure.
9. the method according to claim 8 for measuring milk cow pulmonary artery and right ventricular pressure, which is characterized in that including described
Floating catheter inwardly is continued to press on, when floating catheter enters pulmonary artery and stable pulmonary artery signature waveform occurs, records lung
The step of being carried out after the step of artery mean pressure：
By the air bag deflation of floating catheter, then floating catheter is slowly extracted out from pulmonary artery；
Floating catheter is sterilized using alcohol after jugular vein extraction after floating catheter.
10. the method according to claim 9 for measuring milk cow pulmonary artery and right ventricular pressure, which is characterized in that dynamic to lung
When pulse pressure is tested, pressure sensor and milk cor bovinum keep the same horizontal position.
