Description
Technical field
The present invention relates to blood collection device technical field, specially a kind of vascular surgery blood collection device.
Background technique
Blood is flowed in the red opaque thick liquid of one of the blood vessel of people and heart.Blood is by blood plasma and blood
Cell composition contains 900-910 grams of water, 65-85 grams of protein and 20 grams of lower-molecular substance, low molecule in one liter of blood plasma
There are many electrolyte and organic compounds in substance, and haemocyte includes red blood cell and leucocyte and blood platelet three classes cell.It is red thin
Born of the same parents' average life span is 120 days, and the leucocyte service life is 9-13 days, and platelet life span is 8-9 days.Under normal circumstances, for each person every day all
There is the haemocyte aging death of 40ml.Meanwhile also there is the cell neogenesis of respective numbers.The function of blood include haemocyte function and
Blood plasma function two parts have transport, adjust human body temperature, defence, adjust four functions of human body osmotic pressure and acid-base balance.Mainly
Ingredient is blood plasma, haemocyte, inhereditary material (chromosome and gene).Belong to connective tissue, i.e. organized layer in life system
It is secondary.Contain various nutritional ingredients, such as inorganic salts, oxygen and products of cellular metabolism, hormone, enzyme and antibody in blood, it is nutritious
Tissue adjusts organ activity and defends the effect of harmful substance.Blood storage human health information, many diseases needs test
Blood.Including hereditary disease.The total amount of blood is known as blood volume in human body, is the summation of plasma volume and haemocyte, but in addition to red blood cell,
Its haemocyte quantity is seldom, often ignores.Safety blood is referred to without containing any virus, helminth, drug, alcohol, change
The blood of the foreign substance of damage, danger or disease can be brought to receptor by learning substance or other.The necessary health of blood donor,
Not also not excessively any serious disease.Ying Yin's receptor is not damaged by blood, blood donor also not Ying Yin donate blood and
Incur risk.The color of blood be it is differentiated, the red of blood comes from endoerythrocytic hemoglobin, and hemoglobin is oxygen-containing
When measuring more be in cerise (arterial blood), oxygen content it is few be in kermesinus (venous blood).Pumping of usually donating blood is venous blood, other than institute
Viewing is in kermesinus up.If blood containing it is more be ferrihemoglobin or other haemoglobin dervatives, be in atropurpureus.Blood
(or serum) is starched because containing a small amount of bilirubin, it appears that transparent faint yellow；It is in milky white muddiness if containing chylomicron；If occurring
Haemolysis, then take on a red color blood plasma.
The blood for usually requiring acquisition patient in hospital's checking process is chemically examined, and medicinal blood acquires in the prior art
Device has the disadvantage that in use
1, it needs single acquisition amount less when blood collection, is unfavorable for different department chemical examination and uses, frequently acquisition increases patient
Feeling of pain, influence its normal use.
