Definitions

  • ABSTRACT An aspirated body fluid collection device comprising a transparent, graduated, cylindrical container having a flared mouth and a closure, which fits snugly within the mouth and which can be interlocked therewith, is disclosed.
  • a pair of tubes are molded integrally with the closure to define openings which pass therea through, one tube serving as an aspirated body fluid inlet and the other acting as a vacuum conduit.
  • An antisplash deflector chute is attachable to the inner end of the inlet tube to direct fluid toward the side of the container, and provision is made for an inlet filter to strain solid matter from the body fluid before it reaches the graduated container.
  • a small critical measure receptacle may be secured within'the container when accurate measurement of small amounts of fluid are required.
  • Float valve means may be connected to the inner end of the vacuum conduit to prevent withdrawal of fluid from the container after it is full.
  • the container closure includes a flared peripheral rim carrying on its outer surface a plurality of peripheral flexible ridges which engage the inner surface of the 30 Claims, 13 Drawing Figures PATENTEDAFR 23 29m SHEET 20F 5' ASPIRATOR JAR BACKGROUND OF THE INVENTION
  • the present invention relates, in general, to fluid collection jars, and more particularly to jars for receiving fluids from aspirators used in medical applications.
  • body fluids including blood, which tend to collect there. Removal of such body fluids is generally by means of an aspirator, which utilizes a vacuum to draw the fluids through a suitable tube for deposit in a collection bottle or jar.
  • body fluid storage bottles for use in such systems are well-known in the art, but have not been entirely satisfactory, since they have often been complex, difficult to assemble and use, expensive and often unreliable in operation.
  • a vacuum is produced in the fluid collection jar, thus creating a vacuum in the tube leading to the operation site from which fluids are to be withdrawn.
  • This vacuum carries the fluid through a drainage tube to the inlet port of the bottle. Since it is important in many cases to be able to monitor the flow of such fluids, it is necessary to measure the amount accumulated in the aspirator jar with some degree of accuracy.
  • the prior art has provided means for carrying this fluid to the bottom of the collection container, so that the inlet fluid does not splash and create a foam which would interfere with the volume measurements.
  • splash tubes have been found to create an additional problem, in that they can act as a syphon to carry aspirated fluids back to the operation site if the vacuum in the container is lost.
  • the prior devices have to be carefully made to try to reduce the possibility of losing the vacuum and further means had to be provided toprevent this syphon action, if a vacuum loss should occur.
  • the solutions to such problems have, in the past, resulted in an increased complexity for aspirator fluid collection containers, thus increasing their cost and reducing their reliability.
  • .It is another object of the present invention to provide a simplified aspirator container which is made of molded plastic with a minimum number of parts, where the device is inexpensive, easy to assemble and -use, and thus is reliable and safe.
  • the present invention comprises an aspirated body fluid collection jaw having a transparent, graduated, cylindrical container body portion formed with a flared upper edge, or mouth, which is adapted to receive a similarly flared closure.
  • the flared peripheral edge of the closure is provided with peripheral ridges or ribs which are adapted to engage the mouth of the container to provide an airtight seal.
  • Bayonet-type protrusions are provided around the outer edge of the closure to engage corresponding slots in the mouth of the container, whereby the closure is held firmly in place.
  • This closure arrangement not onlyprovides an airtight seal for the container, but prevents accidental opening which could break the vacuum and interrupt the operation of the aspirator.
  • Integrally molded as a part of the closure, or cover are a pair of spaced tubular ports,
  • a deflector chute Secured to the closure at the inner end of the inlet port and adapted to receive the aspirated fluid is a deflector chute, which causes the fluid flowing into the container to be deflectedagainst the sidewall of the container, to effectivelyprevent splashing and the resultant build-up of foam.
  • a critical measure receptacle may be secured to the closure when it is desired to make accurate measurements of small amounts of fluid
  • This receptacle is a small, graduated vessel arranged to receive the inlet fluid, and is connectable to the undersurface .of the closure in alignment with the inlet port.
  • a deflector may be provided for the critical measure receptacle, or the receptacle may be designed to fit over the deflector chute provided for the main container.
  • An overflow opening' is providedin the sidewall of the receptacle near its top, through which the fluid may flow or be emptied into the larger container.
  • a suitable filter may beplaced in the inlet tube to prevent the entry of solid matter into the container.
  • a float valve mechanism is secured to the inner end of the vacuum conduit to insure that the body fluids drawn into the container cannot flow out through the vacuum line to the vacuum source.
  • the aspirator jar of the present invention preferably is molded from suitable plastic materials whereby a strong, lightweight, reliable, yet economic container is provided. This container meets the requirements of 7 present aspirator systems and overcomes the difficulties of prior containers of this type.
