Vacuum blood collection tube, blood collection unit and device for discriminating test methods

Abstract

Provided are a vacuum blood collection tube, whereby, in the case of collecting blood for inspecting multiple items, each inspection treatment can be adequately carried out while minimizing the pain inflicted on a blood collection subject and thus the blood collection operation can be more efficiently conducted, a blood collection unit, and a device for discriminating test methods. The vacuum blood collection tube comprises a bottomed tubular body having an inner space with a definite capacity therein, and a stopper for air-tightly sealing the open end of said tubular body so as to maintain the inside of the inner space at a definite degree of vacuum, whereby blood is collected, via a hollow blood collection needle, one end of which is pierced into a blood vessel and the other end of which is pierced into said stopper, into the inner space of said tubular body due to the pressure difference between the blood pressure and the pressure in the inner space. The inner space of said tubular body is divided into multiple inner spaces in such a manner that the individual inner spaces respectively have definite capacities depending on the purpose of various blood inspections and the individual inner spaces are also maintained at definite degrees of vacuum respectively. Owing to this constitution, the blood can be collected via the blood collection needle having pierced into the blood vessel and the amounts of the blood collected in the individual inner spaces are respectively appropriate for the purposes of the blood inspections.

Description

technical field [0001] The invention relates to a vacuum blood collection tube, a blood collection unit using the vacuum blood collection tube and equipment for a test method for distinguishing blood collected by the vacuum blood collection tube. Background technique [0002] Blood collection methods in the medical field generally include two methods, one using a syringe and the other using a vacuum blood collection tube. The blood collection method using a syringe requires the collected blood to be dispensed before testing, which is inefficient and risks infection. Therefore, the blood collection method of vacuum blood collection tube blood collection has become the main blood collection method currently used. [0003] Vacuum blood collection tubes generally include a bottomed tube body and a plug that hermetically seals an open end of the tube body so that the internal space of the tube body is maintained at a specified depressurized state. When in use, the blood collect...

Problems solved by technology

[0010] Related to the aforementioned prior art, for the situation where three or more test items are required, it is always necessary to insert a new vacuum blood collection tube into the blood collection tube, and the subject of the blood collection will feel pain many times, so the problem of the traditional blood collection method is not not substantively resolved
