Definitions

  • FIG. 1 A first figure.
  • This invention relates generally to techniques for removing and temporarily collecting fluids by suction as in surgery where blood, other body excretions, medicinal fluids, and other drainage fluids are removed by a sump drain or the like, particularly a suction type device operated by motive power means or by hand.
  • this invention relates to a new and advanced device for carrying out drainage as referred to above, in which negative pressure is utilized to draw drainage fluids into a receptacle of flexible material such as' a plastic bag, in which the drainage fluids are temporary accumulated, and the drainage fluids are subsequently disposed of together with and in the flexible bag.
  • Bodily fluid suction devices presently in use are of a type comprising, essentially a glass bottle or a rigid plastic bottle, a lid such as a rubber stopper disposed in the mouth of the bottle, a suction or evacuating device connected to one of two openings in the lid, and a suction pipe connected at one end thereof to the other opening in the lid and having the function of directly sucking drainage fluids at its other end.
  • the evacuating device By operating the evacuating device to evacuate the bottle inerior, the resulting negative pressure is utilized to draw and remove the drainage fluids into the bottle. After use, the fluids within the bottle are disposed of, and the bottle is washed with water to be used again.
  • an object of this invention is to provide a safe drainage fluid suction device wherein, instead of a glass bottle, a low-price disposable bag made of a flexible plastic material is used to draw off drainage fluids by suction'into the bag for temporary storage by a simple and safe procedure, and the bag thereafter is disposed of together with the fluids contained therein, the entire work being carried out without any physical contact between the operator and the drainage fluids.
  • Another object of the invention is to provide in a device as stated above, means in and by which negative pressure is utilized to draw drainage fluids into the flexible bag, which bag is prevented from collapsing because of the high atmospheric pressure acting on its exterior surface and is held substantially in the form of a container vessel.
  • the device of this invention in which there is provided a rigid vessel having strength for withstanding atmospheric pressure applied to its outer surface and adapted to contain the flexible bag therein thereby to isolate the bag from the outside atmosphere, the interior of the bag being in communication with its exterior, that is, the interior of the rigid vessel when the interior of the bag is evacuated.
  • a drainage fluid suction device comprising a rigid outer vessel, a flexible bag accommodated within said outer vessel, a tube for conducting drainage fluids from a point outside of the device to the interior of the bag, and a vacuum-creating means for evacuating the interiors of the outer vessel and the bag thereby to draw said drainage fluid through said tube into the bag.
  • FIG. 4A is a perspective view showing an embodi- I ment of the suction device of the invention in the case where, within an ordinary outer vessel, a flexible bag with open top is held and accommodated through the use of a support frame;
  • FIG. 4B is a relatively enlarged, fragmentary elevation, view partly in vertical section, showing an embodiment of construction of the a bag rim holder on the support frame;
  • FIG. 5A is an elevation view partly cut away, showing one embodiment of a flexible bag with sealed upper edge
  • FIG. 5B is a similar elevation view showing another embodiment of a flexible bag with sealed upper edge
  • FIG. 6 is a perspective view showing the essential construction of one embodiment of a support frame for supporting a bag as illustrated in FIG. 5A or 58;
  • FIG. 7 is an elevation view showing a modification of the bag used in this invention.
  • FIG. 8 is a relatively enlarged, fragmentary view in section taken along line VIII-VIII in FIG. 7.
  • FIG. 9 is a similar view in section taken along line lX-IX in FIG. 7.
  • FIG. 10 is a fragmentary perspective view, partly cut away, of the parts shown in FIGS.B and9;
  • FIG. 11 is a perspective view, with a part shown in vertical section, showing an embodiment of support means for supporting in suspended state the bag illustrated in FIG. 7 and the upper part of an outer vessel adapted to support, in turn, the support means.
  • the device according to this invention illustrated therein has an outer vessel structure 1 made of a rigid synthetic resin or glass and having a closed bottom and an open top, which can be closed by'a bell-like cover 2 detachably secured to the outer vessel 1 by fastening means 3.
  • the outer vessel 1 and its cover 2 thus form a closed vessel adapted to accommodate therewithin a flexible bag 4 made ofa material such as a flexible synthetic resin and supported at its upper open end, the upper peripheral rim 5 thereof being bent outward and over the upper rim 6 of the vessel 1 and clamped between rim 6 and the lower rim 7 of the cover 2.
  • a rubber packing or gasket 8 is interposed between the lower rim 7 of the cover and the upper rim 6 of the vessel 1 for gas tightness therebetween.
  • the vessel 1 is provided in its side wall at the lower part thereof with a primary suction nozzle 10 having an outwardly projecting end for connection with one end of a length of suction rubber tubing 9 connected at its other end to a vacuum pump (not shown).
  • the interior of the vessel 1 can thereby be evacuated by operating the vacuum pump.
  • the space S outside of and surrounding the flexible bag 4 and formed between the outer surface of the bag 4 and inner surface of the vessel 1 is intercommunicated with the interior I of the bag 4 within the vessel 1 by a length of rubber tubing 11 connected at its lower end to the outwardly projecting end of a secondary suction nozzle 12 in the side wall of the vessel 1 at the lower end thereof.
  • the other, upper end of the rubber tubing 11 is connected to the outer end of a suction metal tube 14 inserted into the vessel interior through a stopper l3 fitted into a central opening in the uppermost part of the cover 2.
  • the inner ends of the above mentioned primary and secondary suction nozzles 10 and 12 project into the interior of the vessel 1 and have holes 10A and 12A, respectively, formed in their lower side walls.
  • the purpose of these holes is to maintain clear passage through the nozzles even when the extreme inner tips of these nozzles abut against and are closed by the bag 4 when suction is applied.
  • the above mentioned stopper 13 of the cover 2 is provided with another through hole, through which a suction metal tube 16 is inserted into the interior of the vessel 1.
  • a suction metal tube 16 is inserted into the interior of the vessel 1.
  • the other, outer end of the rubber tubing 15 is provided with a suction nozzle 15A.
  • the lower inner tip of the metal tube 16 is inserted downward into flexible bag 4 to a level somewhat below that of the upper rim of the bag.
  • the purpose of this is to prevent spattering of the drainage fluids onto the inner surface of the cover 2 ofthe vessel when these fluids injected through the lower end of the metal tube 16 strike the surface of any fluid already accumulated in the bag 4.
  • the outer vessel structure 1 is made of a transparent or translucent material so as to facilitate observation from the outside of the state of the drainage and the drainage fluids being drawn into the bag 4. Furthermore, a graduated scale 17 for indicating the volume of fluids drawn into the bag 4 is provided on the side wall of the bag.
  • the suction device of the above described arrangement operates in the following manner.
  • the aforementioned vacuum pump (not shown) is first started to evacuate the space S around the bag 4, the air being drawn out therefrom through the rubber tubing 9.
  • the negative pressure of the space S draws the air within the flexible bag 4 through the communicating rubber tubing 11, whereby although the bag 4 is flexible, its interior can be evacuated without its collapse and with its shape in its original stage because there is almost no difference in the pressures inside and outside the bag.
  • a special outer vessel provided with a connection nozzle for connection to the vacuum pump and a nozzle for pressure equalization is not used, but an ordinary rigid vessel la is used to accommodate a flexible bag 4a, into which drainage fluids are drawn.
  • the bag 4a is supported and held in opened state by an annular member 20 over and around which the upper edge part of the bag 4a is folded outward and clamped against the member 20 by another annular member 21.
  • the annular member 20 is secured to and supported by a support frame 19, while the upper annular member 21 is slidably connected to vertical members of the support frame 19.
  • the support frame 19 is mounted on a suitable base 18 resting on the bottom of the outer vessel la.
  • the outer vessel la has a gas-tightcover 20 provided with metal tubes 14 and 16 passed through the top of the cover for connection respectively to one end of a rubber tubing 9a connected at the other end to a vacuum pump (not shown) and one end of the aforementioned rubber tubing 15 for drawing drainage fluid as in the preceding embodiment.
  • the space S between the outer vessel 1a and the bag 4a disposed therein is communicative with the interior of the bag 4a through its upper open end within the outer vessel. Accordingly, when the interior of the outer vessel la is evacuated by the vacuum pump, the interior of the flexible bag 4a is simultaneously evacuated, whereby the negatives pressures inside and outside of the bag 4a are maintained in equalized state, and drainage fluids can be readily introduced into this flexible bag.
  • the device Since an outer vessel of special construction is not required by this arrangement, the device is simplified, and since the bag 4a containing drainage fluids can be taken out in its state of being held and supported by the support frame 19, the disposal of the drainage fluids is facilitated and can be accomplished in a sanitary and convenient manner.
  • FIGS. 5A and 5B an outer vessel similar to that in the preceding embodiment illustrated in FIGS. 4A and 4B is used, but, instead of a flexible bag with an open top as is used in the preceding embodiments, a flexible bag made of a material such as a platic with a sealed upper edge is used.
  • the sealed upper edge is provided with a fluid suction inlet and one or more evacuation outlets 26.
  • the fluid suction inlet 25 of the bag 4b is provided separately from at least one evacuation outlet 26, while in the embodiment shown in FIG. 5B, the inlet 25 of the bag 4c is disposed concentrically within the outlet 26 in the form of a tube of relatively large diameter.
  • FIGS. 5A and 5B are held in suspended state within the outer vessel, corresponding to that in FIG. 4, by a support frame 191) as shown in FIG. 6 having a cross beam 28 provided with spaced pins 29, fixedly embedded therein and inserted through matching holes 27, in the upper edge of the bag.
  • a swinging holding plate 30 hinged at one end to the frame 1% is provided with corresponding holes 32, to receive the outer ends of the pins 29, when the holding plate 30 is swung toward the cross beam 28 to clamp and hold the upper edge of the bag 4b (or 4c) therebetween.
