Definitions

  • This invention relates to a collapsible bag which can be used for the collection of material suctioned from parts of the human body.
  • the present invention provides an apparatus which allows the safe use of a collapsible bag for the collection of suctioned fluids allowing for the clean, hygenic, and much more pleasant, disposal of the fluids along with the complete collapsible bag.
  • the present invention may be said to provide a rigid container with a releasable air tight lid, a collapsible bag within the container, a suction port leading through the lid into the collapsible bag, a vacuum port leading through the lid and being in fluid communication with both the bag interior and the volume between the bag and the rigid container.
  • connection to the vacuum port is via a restriction to gas flow so that the vacuum applied to the exterior of the collapsible bag is always greater than, or equal to, the vacuum applied to the interior of the collapsible bag, thus keeping the bag expanded.
  • the suction port is connected to a sterile flexible tube for insertion into the portion of the body where fluids are to be evacuated.
  • FIG. 1 which is a perspective view with internal detail of one embodiment of the invention.
  • FIG. 2 which is a sectioned view showing internal detail of an alternative device embodying the invention. Best Mode of Carrying Out the Invention
  • Fig. 1 shows a rigid container 1 with a cooperative lid 2 and an O-ring seal 3 to provide a gas tight seal therebetween.
  • the lid 2 includes an internal land 4 to which is removably ⁇ ealingly attached a collapsible bag 6 by an O-ring 7.
  • Leading into the interior of the collapsible bag 6 is the suction port 8 and the vacuum port 9.
  • Leading into the container 1, but external of the collapsible bag 6 is an auxiliary port 10. Suitable tubing runs from each of the ports 8, 9 and 10. Tubing from the suction port 8 leads off to the patient and, in use, is inserted into portions of the patient's body where fluid is to be extracted.
  • Tubing connected to the vacuum port 9 and auxiliary port 10 lead off to a common vacuum source.
  • the tubing leading from vacuum port 9 includes a restriction such as an adjustable clamp so that the vacuum applied by the vacuum source to auxiliary port 10 is always greater than or equal to the vacuum applied to vacuum port 9.
  • the tubing to auxiliary port 10 enters the tubing to vacuum port 9 via a venturi attachment so that when air flows through port 9 and past the venturi the pressure gradient across the bag equals the difference between the static and dynamic pressures of the air flow at the venturi ensuring that the collapsible bag 6 is always tending towards a maximum extended configuration even if the tubing connected to the suction port 8 becomes blocked.
  • Fig. 2 shows a container 1 generally similar to that of the previous embodiment.
  • Lid 12 fits neatly into the open end of the container 1 and is sealed therewith by seal 13.
  • Extending through the lid 12 are co-axial inner suction port 8 and outer vacuum port 9.
  • the suction port 8 extends some distance further than does the vacuum port 9.
  • a sponge rubber collar 14 Positioned over this extra length of suction port 8 is a sponge rubber collar 14. The collar 14 fits sufficiently tightly on the suction port 9 so as to prevent it from easily sliding thereof but not so tight as to prevent it from being removed by hand.
  • the plastic bag 6 has a neck 15 including two portions, a first portion 16 adhered to, and frictionally gripping the collar 14 and a second portion 17 being a number of centimetres long and being normally coiled so as not to interfere with placement of the bag 6 onto the suction port 8.
  • the outer walls of the vacuum port 9 include through holes in the region proximate the lid 12 so as to form the auxiliary port 10.
  • a vacuum is applied to the inside of the plastic bag 6 via the collar 14 which acts firstly as a filtering device and secondly as a small air restriction.
  • the filtering function ensures that only air passes up from the bag into the vacuum port 9 while the air restriction function ensures that the pressure outside of the bag 6 is always slightly less than the pressure inside of the bag 6.
  • lid 12 When the bag has been filled, or the particular operation completed, lid 12 is removed and collar 14 pulled off the suction port 8. This removal automatically wipes clean the portion of the suction port 18 which was inside the bag 6. Once the bag 6 is removed from the suction port 8 the coiled portion 17 of the neck of the bag 6 is straightened and tied so as to seal the bag for disposal.
  • the bag will be closed by the resilient contraction of the collar 14.

Abstract

La présente invention se rapporte à un récipient rigide (1) contenant un sac flexible (6). Le sac (6) comporte une seule ouverture contenant un collier en mousse élastique (14) qui s'accroche à un tube d'un orifice d'aspiration (8) et permet un écoulement limité d'air filtré entre l'intérieur et l'extérieur du sac (6). Un orifice de formation de vide (9) est ménagé dans le récipient concentriquement à l'orifice d'aspiration (8) et se termine à proximité du collier (14). Pendant le fonctionnement, l'orifice de formation de vide (9) est relié à une source de vide qui fournit une pression réduite dans l'intérieur du récipient et, par écoulement de gaz à travers l'orifice d'aspiration et le collier (14), une pression réduite dans le sac (6). L'orifice d'aspiration est ensuite relié à un tube stérile servant à l'évacuation d'un fluide corporel chez un patient.
