Container for testing blood and blood sampling instrument

Abstract

A container for testing blood (1A) is provided with: a main container body (2) having an internal space (3) for storing an initial blood flow to be used for testing; a blood inflow port (5) that allows the initial blood flow to flow in; a blood outflow port (6) that allows the initial blood flow to flow out; and an exhaust part (7) that has a hydrophilic bacteria-impermeable filter (12), and allows air in the internal space (3) to be discharged. The container for testing blood (1A) is characterized in that the exhaust part (7) is positioned at the upper end of the main container body (2) when the blood outflow port (6) is used in such a manner as to be in the vertical direction, and has a small-diameter tubular passage (11) that allows air in the internal space (3) to be discharged after a prescribed amount of the initial blood flow has entered.

Description

technical field [0001] The present invention relates to a blood container for testing that collects (stores) initial flow blood for testing, and a blood collection tool having the blood container for testing. Background technique [0002] Generally, a blood collection set includes a venipuncture needle, a blood donation bag for containing blood collected by the venipuncture needle, plastic tubing connecting the venipuncture needle and the blood donation bag, and a branch branched from the plastic tubing, as described in Patent Document 1, for example. Piping accessories and containers (examination blood containers) communicated with plastic piping by means of piping accessories. [0003] When using the blood collection device of Patent Document 1, before collecting (storing) blood from a donor (blood donor) into a blood donation bag, that is, before performing actual blood collection, the donated The initial bleeding of the patient is collected (the initial bleeding is made...

AI Technical Summary

Problems solved by technology

In this way, in the blood collection device of Patent Document 1, since the inflow of the initial bleeding is stopped manually, the timing of closing the clamp differs depending on the operator, and the amount of the initial bleeding collected (stored) in the blood container for inspection will vary. Sometimes taking too much, sometimes not ensuring the minimum dosage

Moreover, in the case of taking too much, it will cause damage to the donor's health and loss of residual blood.

In addition, when the minimum amount to be collected cannot be ensured, various tests cannot be performed using the first bleeding, and the safety of the blood collected into the blood donation bag cannot be ensured.

In particular, when the minimum amount of collection cannot be ensured, the blood collected by the blood collection device cannot be used to produce blood preparations, which will lead to impairment of blood preparations
