Description
Technical field
The application relates to technical field of medical instruments, adopts for being cleaned blood from intravenous more particularly to one
The hemostix of collection.The application further relates to a kind of blood collection instrument utilizing above-mentioned hemostix to carry out blood collection.
Additionally, the application further relates to a kind of blood collection method utilizing above-mentioned hemostix to be cleaned blood collection.
Background technology
In existing blood collection procedure, using and blood taking needle one end is inserted human vein, other end insertion is prefixed negative
In the blood taking tube of pressure, due to the suction function of blood taking tube, blood automatically flows in blood taking tube.But, the blood taking tube of preset negative pressure
Blood sampling volume cannot be accurately controlled when taking a blood sample, blood taking tube necessary preset negative pressure before the use, add production cost, and
There is the risk releasing negative pressure in the blood taking tube of preset negative pressure in transport or moving process, the percent defective causing blood taking tube is high.
For solving above-mentioned technical problem, such as, publication No. is that the Chinese invention patent application of CN 104783815 A is announced
Blood sampling three way cock and hemostix.Which solve the blood taking tube technical problem without preset negative pressure.So in practice, the present inventor
Find that the product using this technical scheme the most at least exists following technical problem: 1). before-mentioned products is inserting blood taking tube
Time, row's blood pin and pin spacing of bleeding are relatively big (3-3.5mm), add the diameter of two pins itself, the maximum transversal on its cross section
Distance is the biggest, therefore, will pay special attention to syringe needle and can not be inserted on the inwall of blood taking tube inserting blood taking tube when, no
Then it is easy for polluting in blood taking tube；2). before-mentioned products due to row's blood pin and bleed pin spacing relatively big (3-3.5mm) and
And syringe needle is one in front and one in back, when being inserted into blood taking tube, active force can produce a sudden change, thus operator holds when update
Being easily generated vibration causes deflection to be likely to be such that syringe needle is inserted on the inwall of blood taking tube.
Therefore, how to improve and optimize hemostix so that it is simple in construction, by means of this hemostix so that applying this blood sampling
When device is taken a blood sample easy to operate, reliability is high and blood taking tube inwall produces the probability destroyed little is technology in this area
