Simple negative pressure blood culture bottle for diagnosing infection pathogenic bacteria

Abstract

The invention discloses a simple negative-pressure blood culture bottle for diagnosing infection pathogenic bacteria. The simple negative-pressure blood culture bottle comprises a bottle body, a bottle cap, scales and a culture medium, the bottle cap is arranged above the bottle body; the culture medium is arranged in the bottle body, and the pH value of the culture medium is 7.4 + / -0.5; the movable ring is arranged on the outer side of the bottle body, and a rotating ring is connected to the upper portion of the outer side of the bottle body through a bearing; and the sliding piston is clamped in the bottle body in a sliding mode, upper ropes are fixed to the left side and the right side of the upper portion of the sliding piston, and the other end of the upper rope on the left side is connected with a winding disc. According to the simple negative-pressure blood culture bottle for diagnosing infection pathogenic bacteria, the total volume of blood and a culture medium is observed through scales, the interior of the bottle is convenient to observe, the situation that the internal volume is inconvenient to observe when the bottle is inclined is avoided, glue left on old labels is treated through a scraper and a water absorption sponge, and the working efficiency is improved. The glue is prevented from adhering to other objects.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simple negative pressure blood culture bottle for diagnosing infected pathogenic bacteria. Background technique [0002] Blood culture flasks are used in clinical medicine for the rapid cultivation and detection of bacteria, fungi and mycobacteria.
