Description

Vacuum blood collection tube with holes

Technical Field

The utility model relates to a centrifugal sediment taking detection device, in particular to a vacuum blood collection tube with holes.

Background

Centrifugation is a commonly used method of separating solid phase material from a mixed liquid phase. The centrifugal tube used in the existing centrifugation is a centrifugal tube with a taper at the bottom and directly closed, and the method for taking out the separated solid-phase substances is to obtain the solid-phase substances from the pouring liquid end of the centrifugal tube, so that the centrifugal tube is inconvenient to use under certain conditions, and if the solid-phase substances are few, the solid-phase substances are often difficult to take out or even cannot be taken out from the pouring end; in addition, sometimes, the solid phase substances are not easily concentrated due to the large area of the bottom of the conical tube of some centrifuge tubes, so that the acquisition, detection, analysis and the like of the sediment after centrifugation are influenced.

Disclosure of Invention

In order to solve the above technical problems, an embodiment of the present invention provides a vacuum blood collection tube with a hole, wherein a suction hole is formed in the bottom of the vacuum blood collection tube, one end of the suction hole is connected to a tube cavity of the vacuum blood collection tube, the other end of the suction hole extends out of the bottom of the vacuum blood collection tube, and a plug is hermetically connected in the suction hole.

Wherein, the thickness of the bottom of the vacuum blood collection tube is 1 to 3 times of the thickness of the tube wall.

Preferably, the vacuum blood collection tube is made of medical rubber or silica gel, the aperture of the suction hole is 0.1mm-50mm, the height of the suction hole is 0.1mm-50mm, and the diameter of the plug is plug.

Wherein, the end cap is one of a T-shaped rubber cap and a screw cap which are arranged in the suction hole in a detachable plug mode.

The end cap is an inverted U-shaped rubber cap, a rubber convex nail is integrally formed at the inner bottom of the U shape of the inverted U-shaped rubber cap, the end part of the injector is clamped in an annular cavity formed by the rubber convex nail and the side wall of the inverted U-shaped rubber cap in a surrounding mode, and the suction needle is inserted into the tube cavity of the vacuum blood collection tube from the rubber convex nail.

The plug can also be an H-shaped end socket with a pierceable rubber pad, and the H-shaped end socket is embedded in the suction hole.

The plug is an embedded seal head with a pierceable rubber pad, and the embedded seal head is embedded into the suction hole.

The technical scheme of the utility model has the following beneficial effects: the utility model can fully obtain the solid-phase substances precipitated at the bottom of the centrifugal tube after separation, directly extract the solid-phase substances from the bottom of the centrifugal tube, and can avoid the pollution of the separated substances.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the embodiment of the utility model provides a perforated vacuum blood collection tube, the bottom of which is provided with a suction hole 1 that can be inserted into a syringe or a needle, one end of the suction hole 1 is connected with the lumen of the vacuum blood collection tube 2, the other end extends out of the bottom of the vacuum blood collection tube 2, and a plug 3 is hermetically connected in the suction hole 1.

In this embodiment, the thickness of the bottom of the vacuum blood collection tube 2 is designed to be 1-3 times of the thickness of the tube wall, which is convenient for opening the hole.

The vacuum blood collection tube is generally made of medical rubber or silica gel, and has a suction hole with a diameter of 0.1mm-50mm at the bottom, wherein the thickness of the bottom of the vacuum blood collection tube is 0.1mm-50mm, and the height of the suction hole is 0.1mm-50 mm.

As shown in fig. 2, the plug is one of a T-shaped rubber cap (fig. 2 a) and a screw cap (fig. 2 b) which can be separately plugged into the suction hole, or other commercially available caps which can be plugged into the suction hole to perform a sealing function. When the sediment is extracted, the T-shaped rubber cap or the screw cap is pulled out from the suction hole.

The plug can also be an inverted U-shaped rubber cap shown in figure 3, a rubber convex nail is integrally formed at the inner bottom of the U shape of the inverted U-shaped rubber cap, the end part of the injector is clamped and fixed in an annular cavity formed by the rubber convex nail and the side wall of the inverted U-shaped rubber cap, so that the liquid is prevented from leaking laterally, and the suction needle is inserted into the tube cavity of the vacuum blood collection tube from the rubber convex nail.

The plug is an H-shaped end enclosure with a pierceable rubber pad as shown in fig. 4, the H-shaped end enclosure is embedded in the suction hole, and the end enclosure is directly punctured by a needle head without being taken down in a removable manner.

The plug can also be an embedded sealing head with a pierceable rubber gasket as shown in fig. 5, and the embedded sealing head is embedded in the suction hole.

The working principle of the utility model is as follows: after centrifugation, solid-phase substances are precipitated at the bottom of the centrifuge tube, liquid-phase substances above the solid-phase substances are poured out from the pouring end of the centrifuge tube, then the plug is pulled out from the suction hole or the needle head punctures to the bottom of the centrifuge tube from the plug, and the solid-phase substances are extracted, so that the solid-phase substances are not polluted when being taken out.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
