of 1 to 7, sanitary samples made in accordance with the disclosure of the present invention A preferred embodiment of the management system 10 is shown. Figures 1, 2 and 7 As best illustrated, the present invention consists of four essential parts, namely: the stem part 1; 4. Assemble the stopper portion 16, orifice plate fixture 18 and clamp 20. and which, when assembled, are in direct fluid communication with a fluid-containing enclosure (not shown). together with the free end 13 of the tube 12 to form an airtight sanitary seal.

In assembling the device of the invention, one first connects the fluid enclosure (not shown). The tube 12 must be open and in fluid communication. freedom of tube 12 The end portion 13 is of standard dimensions, which allows the stem portion 14 to slide and prevent friction. The stem portion 14, which can be held in place by fitting or adhesive, is substantially It is tubular in shape and includes an outwardly extending region 69, which region 69 extends. Finally, an upper raised portion 70 is formed which has a larger diameter than the lower portion 71 directly below the region 69. do. As illustrated in FIG. 6, the top surface 72 of the stem portion 14 is It is provided with a channel 73 extending over a distance. Inner edge 7 of top surface 72 4 extends inwardly, thus opening 77 has a straight diameter smaller than the diameter of stem inner surface 76. It has a diameter. This forms a seat member 75, as shown in FIG. A stem portion 14 is attached to the tube 12 to ensure a tight seal.

Stopper portion 16 is designed to fit tightly within stem portion 14 and tube 12. It is. Stopper portion 16 has a lower tail portion 19 which is shaped like It is cylindrical in shape and has an integrally formed disc-shaped head portion 21. Ru. Various model bumps 17 are present on the outer surface 23 of the tail portion 19. The stopper portion 16 prevents the stopper portion 16 from sliding out from within the stem portion 14. similarly , a channel 73 on the top surface 72 of the stem portion 14 is connected to a stem portion 14, which will be described in more detail below. To prevent movement of the stopper portion 16 or leakage of fluid around the stopper portion 16. It is in direct contact with the lower surface 25 of the head portion 21 so as to

An orifice plate is provided on the upper surface 27 of the head portion 21 of the stopper member 16. The mounting tool 18 is the position. As illustrated in Figures 5 and 6, the orifice For mounting the base plate, the fixture 18 is substantially disc-shaped and slopes slightly upwards. It has a top surface 63 and an opening 66 extending through its center. orifice ・For plate installation, there is a channel 62 on the bottom surface 64 of the tool 18. The flannel, like the channel 73, prevents movement of the stopper portion 16 and completely Prevents fluid leakage when assembled.

The clamp 20, shown in detail in FIG. The orifice plate attachment maintains fixture 18 in tight, sealed communication. Kula The pump 2o has two parts: a main arm part 22 and an auxiliary arm part 24. It is a 360 degree clamp. The main arm portion 22 has an upwardly extending means 32 extending therethrough. comprising rod means 60 secured by the pin 30 between the extending downwardly extending means 34; There is. The free end 78 of the rod means 60 has a threaded engagement means 28 and a wing nut engaged therewith. A handle 26 is provided. The main arm portion 22 also extends upwardly extending means. 40 and an extended downwardly extending means 42 opposing the extending means 32 and 34. . The main arm section 22 is provided with a 180 degree curve, as is the case with the auxiliary arm section 24. It is growing. The auxiliary arm portions 24 are additionally binned therebetween by a bin member 44. The upwardly extending means 40 and the downwardly extending means of the main arm portion 22 act as hinges. 42 is provided with an intermediate extension body 46 that fits between the two. Middle extension of auxiliary arm portion 24 Opposing the body 46 are an upwardly extending portion 56 and a downwardly extending portion 58 . Rod member 6 0 can be positioned between upper extension 56 and lower extension 58, respectively.

When the rod member 6o is thus positioned, the butterfly handle 26 is engaged by the screwing means 28. The clamp 20 can then be tightened between the stem portion 14 and the stopper. 16 and orifice plate fixture 18. Clamp 20 When positioned such that the upper edge 36 of the main arm portion 22 and the auxiliary arm An upwardly extending edge 48 of portion 24 is located at one side of upper surface 63 of orifice plate fixture 18. overlapping parts. Similarly, the lower edge 38 of the central arm portion 22 and the auxiliary arm portion 2 The downwardly extending portion 5o of the stem portion 14 overlaps a part of the region 69 extending outwardly of the stem portion 14. Ru.

Once the clamp 20 is firmly tightened around the other three parts of the device, the The head portion 21 of the topper 16 connects to the stem portion 14 and the orifice plate fixture. It is compressed between 18 and 18. However, the stopper portion 16 is connected to the channel 73. In the area of the channel 62, the head portion 21 is not compressed and thus the channel extending into channel 73 and into channel 62 and interacting therewith as shown in FIG. Made of elastic material so as to be locked. Preventing fluid communication between the inside and outside of tube 12 This interlocking action achieves a strong hermetic seal. This is a pollutant As with leakage, fluid within the tube 12 is prevented from entering the interior.

Once assembled, the sanitary sample is then clamped onto the needle portion 80 of the syringe 82. into the upper opening 84 in the orifice plate fixture 18. 66 and the stopper 16 to be in direct communication with the fluid in the tube l. It can be collected by doing. The sample then moves the plunger 86 into the syringe housing. 88 and then pull the stock out as well as the sampling system. Removal of needle portion 80 from within par 16 allows retraction from tube 12. This method is It can be repeated many times without sample leakage or contamination.

Stop portion 16 of the preferred embodiment can be made of resilient synthetic material or natural rubber. It is. The remainder of the sanitary sampling system according to the invention is made of rigid synthetic material. materials, metals. It can be made of wood or a combination of similar solid materials.

The dimensional relationships of the present invention are standardized to be compatible with a variety of standard sized tubes.

The foregoing has been a description of preferred embodiments of the invention.

Although many specific details have been described, this description does not serve to illustrate the invention. It should be understood that the purpose is not to limit the invention. Furthermore, this specification The configuration of the sanitary sampling system proposed in this document is included in the following claims. It is also to be understood that, except as limited, it is not limited in any way.
