Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, 2 and 3, the present embodiment provides a blood culture bottle, including a bottle body, the bottle body includes a bottle body 1 and a bottle neck 11, a stopper cap 3 for sealing the bottle body is disposed on the bottle neck 11 (at the bottle neck), a bottle cap 2 is sleeved on the stopper cap 3, a piston 4 is disposed in the bottle neck 11, a first negative pressure cavity 13 is formed between the piston 4 and the bottle body 1, a second negative pressure cavity 14 is formed between the piston 4, the stopper cap 3 and the bottle neck 11, negative pressures are disposed in the first negative pressure cavity 13 and the second negative pressure cavity 14, and blood is pumped into the bottle body by the negative pressures.

In order to prevent the piston 4 from moving, the pressures in the first negative pressure cavity 13 and the second negative pressure cavity 14 are equal, the pressure of the negative pressure can be set according to the required blood volume, and if 10mL of blood volume is required to be extracted, the negative pressures capable of extracting 5mL of blood volume are arranged in the first negative pressure cavity 13 and the second negative pressure cavity 14, so that excessive or too little blood is prevented from being extracted, and the blood collection volume can be well controlled; the piston can also separate the medicine bottle in the bottle to prevent the medicine in the culture bottle from reacting before culturing blood.

In this embodiment, a clamping component for fixing the bottle cap 2 on the bottle neck 11 is disposed between the bottle neck 11 and the bottle cap 2, and the clamping component includes a clamping member 12 fixedly disposed on one of the bottle neck 11 and the bottle cap 2, and a clamping groove disposed on the other, where the clamping member 12 is located in the clamping groove; the clip 12 and the clip groove are used for preventing the bottle cap 2 from separating from the bottle body.

In another embodiment, the bottle neck 11 and the bottle cap 2 are in threaded connection, the bottle cap 2 can be removed from the bottle body, and a proper bottle cap connection mode is selected according to different application requirements.

Referring to fig. 4, in this embodiment, a through hole is formed in the bottle cap 2, the through hole is vertically penetrated, a flip 21 is detachably connected in the through hole, and a locking component is disposed between the bottle cap 2 and the flip 21.

Wherein, the locking component comprises a locking groove 20 formed on one of the bottle cap 2 and the flip 21 and a locking piece 210 positioned on the other; when the locking member 210 is in the locking position, the locking member 210 is positioned within the locking groove 20.

Referring to fig. 3 and 4, when a bleeding end of a blood drawing needle needs to be pierced through the plug cover 3 during blood drawing, the plug cover 3 is not suitable to be too thick or too thin, the plug cover 3 is difficult to pierce, the plug cover 3 is difficult to seal due to too thin, in this embodiment, a groove 30 is formed in the plug cover 3, and the thickness of the top wall of the plug cover 3 along the direction from the edge to the groove 30 tends to increase; during puncturing, the thinnest groove 30 of the plug cover 3 is punctured, so that the puncture is convenient, and the thicker part of the plug cover 3 has tightness; when the blood drawing is completed, the flip cover 21 is covered, and the bottom of the flip cover 21 is abutted on the periphery of the groove 30.

It should be noted that, as shown in fig. 3 and 4, the cross-sectional shape of the flip cover 21 is that a groove is formed at the bottom center of the flip cover 21, which not only can save material, but also can prevent blood on the stopper cover 3 from being pressed out by the flip cover 21 and being exposed to air when the flip cover 21 is covered.
