Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model discloses the standard part that uses in all can purchase from the market, and dysmorphism piece all can be customized according to the description with the record of drawing of description, and the concrete connection mode of each part all adopts conventional means such as ripe pasting among the prior art, and simultaneously, in order to express the relation of connection and theory of operation between each component clearly, the description drawing adopts the mode of the sketch of mechanism motion to arrange in order and draws, does not detailed here again.

The utility model provides a take poisonous gas leakage prevention pathology of rotary seal piece to preserve test tube, includes test tube body 1, set up fixed block 2 in the test tube body 1,

fixed block

2 and 1 inner wall sealing connection of test tube body, 2 bottoms of fixed block or top set up sealed piece 3, rotate between sealed piece 3 and the fixed block 2 and be connected, all set up through-hole 4 on fixed block 2 and the sealed piece 3, through-hole 4 on the fixed block 2 communicates with each other with through-hole 4 on the sealed piece 3. The utility model discloses a rotary fit of fixed block and sealed piece not only can effectively soak pathology sample in formalin solution, when needs take out pathology sample moreover, can take out pathology sample from the test tube after pathology sample and formalin solution separate, reduces volatilizing of formalin solution, reduces the harm to operating personnel and environment.

Further, set up dwang 5 on the sealed

piece

3, 5 tops of dwang are located test tube body 1 outside, can dismantle fixed connection between dwang 5 and the sealed piece 3. Due to the arrangement of the rotating rod, an operator can conveniently control the rotation of the sealing block, and the convenience of rotation of the sealing block is enhanced.

Further, a damper is arranged on the sealing block 3 and is located at the position where the sealing block 3 is connected with the fixing block 2. The damper enhances the stability of the sealing block in a static state when the sealing block stops rotating, reduces interference and improves the sealing and separating effects of the solution.

Preferably, the number of the through holes 4 is multiple, the distribution of the through holes 4 on the fixed block 2 and the sealing block 3 is not more than half of the cross section area of the through holes, and the through holes 4 on the fixed block 2 are all located within the range of the outer boundary of the sealing block 3. The setting of a plurality of through-holes has strengthened the circulation efficiency of solution, has further improved the flexibility that the test tube was adjusted.

Example 1:

in this embodiment, the through-hole on fixed block and the sealed piece is stopped up respectively, and formalin solution is located sealed piece and fixed block lower part, at first opens the stopcock of test tube, puts into the test tube with pathological specimen, stops up the mouth of pipe with the stopcock afterwards. Then operating personnel holds the test tube, and the rotatory test tube of horizontal direction, under the inertial action, sealed piece is rotatory, and the through-hole on sealed piece and the fixed block communicates with each other, and operating personnel slope test tube makes formalin solution flow in test tube upper portion through the through-hole, then the rotatory test tube of horizontal direction, under the inertial action, sealed piece is rotatory, and the through-hole on sealed piece and the fixed block is closed, and pathological sample soaks in formalin solution. When pathological samples need to be taken out, the test tube is rotated in the horizontal direction, the sealing block is rotated under the action of inertia, the through holes in the sealing block and the fixing block are communicated, formalin solution flows to the lower section of the test tube, and after the pathological samples are separated from the formalin solution, the bottle plug is opened to take out the pathological samples.

Example 2:

in this embodiment, on the basis of above-mentioned embodiment, set up dwang 5 on above-mentioned sealed piece 3, dwang 5 top is located test tube body 1 outside, can dismantle fixed connection between dwang 5 and the sealed piece 3. Due to the arrangement of the rotating rod, an operator can conveniently control the rotation of the sealing block, and the convenience of rotation of the sealing block is enhanced.
