Test tube plug for airtight body fluid retention device

Technical Field

The utility model relates to plugging equipment, in particular to a test tube plug for plugging and connecting a test tube orifice.

Background

In the open end of test tube was arranged in to prior art's test tube subassembly, but after the collection body fluid was accomplished, when detecting machine carried out physicochemical analysis and detected on the test tube subassembly, when detecting instrument's probe was in deep test tube subassembly, if the probe did not have in tangential position, had the condition of probe by test tube stopper's expansion end to block to take place often, once the probe atress was greater than 0.1N, then can cause the machine to report to the police, needs manual intervention.

Conventional solutions:

1) The thickness of the movable part is reduced, even if the thickness of the movable part is reduced by 50%, when the probe of the detection machine is clamped by the movable end of the test tube plug, the detection machine still can give an alarm, and the movable part after the thickness is reduced can not ensure that the liquid in the test tube can leak when the tube assembly is inclined or inverted.

2) The number of the movable parts is increased, but after the number of the movable parts is increased greatly, the supporting force of the movable parts is insufficient, so that when the test tube assembly is inclined or inverted, liquid in the test tube can leak, and the requirement of on-machine detection of the test tube assembly is still not met.

Therefore, how to provide a test tube plug which can ensure the smoothness of the detection process, avoid manual intervention, and effectively ensure that the liquid in the test tube assembly cannot leak after the test tube plug is matched with the test tube becomes a technical problem to be solved in the industry.

Disclosure of Invention

One of the objects of the present utility model is.

One of the objects of the utility model is achieved by:

the body of the test tube plug is provided with a movable part and a fixed part, and the movable part can move relative to the fixed part, so that the test tube plug can be used for sealing the body fluid retention device: the movable parts are formed by downwards extending the fixed parts, the number of the movable parts is not less than 6, the inner arc length of the cross section of the root part of each movable part is not more than 15.5% of the maximum circumference of the inner side surface of the fixed part, and the diameter of the circumference of the inner root part of each movable part is larger than the diameter of the minimum part of the fixed part. The number of movable parts may be 6, 7, 8, etc., but is not limited thereto.

In the above scheme, the tangent line between the movable parts extends to the connection part of the fixed part and the movable part.

In the scheme, the inner side surface of the fixing part is in a horn mouth shape with a small upper part and a big lower part; the inner side surface of the fixing part may be cylindrical.

In the above scheme, the shapes of the movable parts are the same, namely the movable parts are equally divided; the movable part can also be

In the above scheme, the distance between the root parts of the two movable parts is not less than 70% of the enclosing diameter of the movable parts.

1. When the tangent line between the movable parts extends to the joint of the fixed part and the movable part, the resistance of the movable part to the probe of the detection equipment can be effectively reduced by 30%.

2. When the number of the movable parts of the movable part is not less than 6, the resistance of the movable part to the probe of the detection equipment can be effectively reduced by 70%.

3. The diameter of the root circle of the inner side of the movable part is larger than the diameter of the minimum part of the inner side of the fixed part, so that the movable head of the movable part can be effectively guided to be touched by the probe of the detection equipment, the root of the movable part can be effectively prevented from being touched by the probe of the detection equipment, and the resistance of the movable part to the probe of the detection equipment can be effectively reduced.
