Description
Technical field
The utility model relates to the technical fields of animal physiological, more particularly, to a kind of measurement milk cow pulmonary artery and right ventricle
The device of pressure.
Background technique
Tibet region is that traditional herding sparetime university, China saves.Recently as mentioning 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 becomes the whole world and cultivates most milk cows.High aititude low-oxygen environment is for holstein cow
It is a huge physiology challenge, is to lead to milk in regional due to hypoxemia caused by pulmonary hypertension of the height above sea level higher than 2000 meters
The main reason for ox is dead.The kinds such as holstein cow, Jersey, the Angus beef of Qinghai-Tibet Platean cultivation have generation plateau
The report of disease, especially with the disease 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 between 2017-2022
100000 cow heads are cultivated to Tibet region, but in the introducing process of early stage altitude sickness cause higher proportion milk cow it is dead
It dies, 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 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 ox altitude sickness generation for the first time in 1915 is higher than 1524 meters in height above sea level
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 drawn at 4000 meters or more
Sa city height above sea level transports the holstein cow to high altitude localities at 3658 meters, therefore from plains region, and the disease incidence of altitude sickness exists
60% or more, the 40% of death rate Zhan Quanqun.There are no effectively preventing measures for altitude sickness so far, can only find as early as possible
Infected cattle 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 hearts, lung on milk cow at present
Arterial pressure measurement method.

After the utility model is by measuring pulmonary artery and right ventricular pressure to yak, hiding ox, catalo, holstein cow etc.
It was found that: the present apparatus can quickly and accurately measure the pulmonary artery and right ventricular pressure of each kind ox, and can accurately diagnose
With identification plateau infected cattle and altitude acclimatization milk cow.
The cost calculation of 30,000 yuan of a cow head is introduced according to Lhasa city:
The pasture of one 2000 cow head, the nearly 30% altitude sickness death rate, if it is possible to by measuring pulmonary arterial pressure
Power early detection infected cattle simultaneously sells infected cattle as early as possible, is equivalent to the death for reducing 600 cow heads, directly reduces 18,000,000 yuan
Economic loss.
The method of measurement milk cow pulmonary artery and right ventricular pressure provided by the embodiment of the utility model, comprising steps of firstly,
The jugular vein of milk cow, and fixed puncture needle are punctured using puncture needle, form the extraneous and intracorporal interface channel of milk cow；Then, will
Floating catheter 400 introduces jugular vein along puncture needle, pushes floating catheter 400 that floating catheter 400 is made to enter right ventricle, to
400 injecting heparin sodium solution of floating catheter, anti-Hemostatic Oral Liquid solidify in floating catheter 400, to be seen to the right side by display 200
400 air bag of floating catheter is played after ventricular pressure characteristics waveform；Floating catheter 400 inwardly is continued to press on, to floating catheter 400
It when into pulmonary artery and there is stable pulmonary artery signature waveform, takes multiple measurements, records mean pulmonary arterial pressure.This is practical new
The method of measurement milk cow pulmonary artery and right ventricular pressure that type embodiment provides is easy to operate, measurement is accurate, can Early Identification and
It was found that plateau infected cattle (pulmonary artery pressure is greater than 49mmHg), pasture can sell or treat as early as possible altitude sickness, to reduce height
