  • the chambers 12, 14, I6 and 18 are interconnected in fluid communication by means of integral connectors and relatively short pieces of tubing in the illustrated embodiment.
  • these connections may be formed by integral connectors fitting one within the other, for example, by making each such piece of tubing an integral portion of one of the chamber members.
  • tubing 24 may be formed integrally with the connector 22a as a relatively flexible part of chamber 12, and the connector 26a, integral with liquid seal chamber 14 may be inserted directly into the integral flexible part.
  • the integral connectors and tubing elements provided a simple and effective means for manually releasably connecting the chambers in fluid communication with each other.
  • the present device provides additional means by which the members are securely held together to avoid any possible inadvertent opening in any of the fluid paths. This is accomplished in the illustrating embodiment by providing a plurality of locking or clamping elements shown as connecting pins 60 extending between adjacent portions of the chambers.
  • the chambers 8, 9, 10 and 11 are shown provided with integral tabs or extensions indicated respectively at 61a, 61b, 61c and 61d, and each tab is provided with a hole 62.
  • each of the tabs 61 on one of the members extends over a portion or tab 61 of the adjacent chamber member with the holes 62 in aligned relation to receive a connector pin 60, for example, as shown in FIG. 3.
  • a pin 60 is shown extending through a tab 61c of the regulating manometer chamber member 10 and tab 61b of the liquid seal chamber member 9.
  • Each pin 60 is enlarged intermediate its ends so that when pushed through the aligned holes 62 in the adjacent chambers, the enlarged portion forms a tight frictional engagement with hole 62 tending a hold the adjacent overlapping portions or tabs in tight frictional engagement.
  • a pin locking member 70 such as a star locking washer which may be formed of a resilient metal, over the end of each pin opposite the head with the locking member digging into the pin to further insure that the pin cannot fall out.

  • a connecting tube 87 is shown in fluid communication with tube 20 and connector 19a and has its lower end disposed below the surface of the liquid.
  • the upper connector 22a is open to atmosphere to allow air or gas to escape through the liquid to atmosphere.
  • the connector 50 may be closed by a closure cap 88. With this arrangement liquid in the chamber 12 provides a seal and drainage flows into chamber 12 due to gravity.
  • the lower end of tube 87 is positioned a predetermined distance below the water fill level 89 so that drainage liquid first fills channel 120 and then flows over partition 21a to fill the next successive channel 12b. In this way, the lower end of tube 87 is disposed a constant distance below the liquid level in channel 12a after it is filled to provide a substantially constant reaction force to the flow of fluid from the patient.

  • the outlet 30a is open to atmosphere in the case, and the connectors 50 and 34a are closed by cap 88 and another cap 89, respectively.
  • Chamber 12 is not filled with water in this case since liquid seal chamber 14 is connected to it. Fluids drain by gravity into collector chamber 12 of member 8 and gas or air passes through liquid seal chamber 14 to atmosphere.
  • the chambers 12, I4 and 16 are interconnected and the outlet 50 is sealed off the cap 88 since the direct reading manometer is not used.
  • the outlet 30a is connected to the negative source of pressure 32 by tube 33, and the pressure regulating manometer is connected to the liquid seal to limit the pressure applied to the collector chamber.
  • the operation of this system is similar to that previously mentioned herein connection with the drive shown in FIG.
