Description

Technical Field

[0001] The utility model relates to the field of samplers, in particular to an endocrine effusion sampler. Background Art

[0002] Endocrine system, an anatomical term, is referred to as endocrine system for short. It refers to the endocrine glands throughout the body. It is another important functional regulation system besides the nervous system. It can be divided into two categories: one is the visible organs that exist independently in morphology and structure, namely endocrine organs, such as pituitary gland, pineal gland, thyroid gland, parathyroid gland, thymus gland and adrenal gland; the other is the endocrine cell clusters dispersed in other organs and tissues, namely endocrine tissues, such as islets in the pancreas, interstitial cells in the testicles, etc. Effusion refers to the situation where there is an increase in the amount of fluid in some parts or organs of the body where there should not be fluid or there should be a small amount of fluid. When fluid accumulates in an organ or tissue in the endocrine system, it is necessary to sample it through a sampler. However, since the liquid drawn by the sampler is easily contaminated by external impurities, such as impurities in the sampler pipe, most samplers use mid-section liquid when sampling to make the results more accurate. However, it is not easy for existing samplers to select mid-section liquid, so it needs to be improved. Utility Model Content

A slope 6 is provided on the upper portion of the No. 1 sealing ring 5 between the No. 1 sealing ring 5 and the No. 2 sealing ring 7. The slope 6 is also located on the inner side of the test tube 1. An outlet 8 is fixedly installed on the connecting ring 3. The No. 1 sealing ring 5 and the No. 2 sealing ring 7 are provided on the inner and outer sides of the test tube 1 for sealing. When the test tube 1 moves upward, the inner and outer walls of the test tube 1 move on the No. 1 sealing ring 5 and the No. 2 sealing ring 7 respectively. When the mouth of the test tube 1 moves to the position of the slope 6, the sealing state between the test tube 1 and the No. 1 sealing ring 5 is released, and the sealing between the test tube 1 and the No. 2 sealing ring 7 continues to prevent the liquid from flowing to the upper position of the connecting ring 3.

[0020] A connecting tube No. 1 9 and a connecting tube No. 2 10 are fixedly connected to the middle position of the bottom plate 2, one end of the connecting tube No. 1 9 and the connecting tube No. 2 10 passes through the inner platform 4 and extends into the test tube 1, the other end of the connecting tube No. 1 9 is fixedly connected to a hose No. 11, and the connecting tube No. 1 9 is fixedly connected to a liquid-pipetting needle 12 via the hose No. 11, the other end of the connecting tube No. 2 10 is fixedly connected to a hose No. 2 13, and the connecting tube No. 2 10 is fixedly connected to a syringe 14 via the hose No. 2 13, one side of the test tube 1 is connected to the liquid-pipetting needle 12 via the connecting tube No. 1 9 and the hose No. 11, and the other side of the test tube 1 is connected to the syringe 14 via the connecting tube No. 2 10 and the hose No. 2 13, so that the syringe 14 forms a negative pressure by sucking the gas in the test tube 1, so that the test tube 1 is convenient for sucking the accumulated fluid.

[0021] It should be noted that the utility model is an endocrine effusion sampler. The test tube 1 is inserted into the connecting ring 3. The test tube 1 is movably connected to the No. 2 sealing ring 7. The No. 1 sealing ring 5 is movably connected to the outer wall of the test tube 1, so that two layers of sealing are formed on the inner and outer sides of the test tube 1 through the No. 2 sealing ring 7 and the No. 1 sealing ring 5. Then the push rod of the syringe 14 is pulled. After the push rod is pulled partially, the syringe 14 sucks part of the gas in the test tube 1 through the No. 2 hose 13, so that the gas in the test tube 1 is Negative pressure is formed, and the negative pressure in the test tube 1 causes the test tube 1 to draw the accumulated fluid in a certain organ or tissue of the endocrine system through the No. 1 hose 11 and the aspiration needle 12. The accumulated fluid enters the test tube 1 through the No. 1 hose 11 and the No. 1 connecting tube 9, and the accumulated fluid accumulates on the inner platform 4. Then the test tube 1 is pulled upward, so that the mouth of the test tube 1 moves upward to the position of the slope 6 of the No. 1 sealing ring 5, so that the sealing state between the test tube 1 and the No. 1 sealing ring 5 is released, so that the liquid in the test tube 1 flows out from between the slope 6 and the test tube 1. The liquid flows out of the gap and flows into the bottom plate 2 and is located in the connecting ring 3. The outer position of the connecting ring 3 is fixedly connected with an outlet 8, so that the liquid flows out through the outlet 8. An external container is arranged below the outlet 8 to receive the accumulated liquid. Since the sealing state of the test tube 1 and the No. 1 sealing ring 5 is released, the negative pressure in the test tube 1 is eliminated, and the power for sucking the accumulated liquid disappears. When the accumulated liquid in the test tube 1 flows out, the test tube 1 is worked downward, so that the test tube 1 moves downward on the No. 1 sealing ring 5, so that the test tube 1 The mouth of the tube moves downward and contacts the bottom surface of the bottom plate 2, so that the test tube 1 and the No. 1 sealing ring 5 are sealed again, and then the syringe 14 continues to suck the gas through the push rod, so that the gas in the test tube 1 forms a negative pressure again, so that the test tube 1 sucks the accumulated liquid again, thereby drawing the middle liquid. When an appropriate amount of accumulated liquid is drawn, the liquid aspiration needle 12 is pulled out, and the test tube 1, the bottom plate 2 and other structures are inverted to collect the accumulated liquid in the test tube 1. By detecting the accumulated liquid in the middle section of the test tube 1, the result is more accurate.
