Definitions

  • ABSTRACT A' surgical drainage system including a container for collecting fluid drained from a cavity, such as a pleural cavity, and a drainage tube for placing the container in fluid communication with a cavity to be drained, is provided with a check valve in the drainage tubeJ
  • the check valve permits the flow of fluid from the cavity to the container and prevents the flow of fluid in the opposite direction thus permitting the development of a high negative pressure in the cavity.
  • the check valve comprises an elongate tapered tube which can be positioned inside the drainage tube with itswide end towards the cavity.
  • the tapered tube is provided with an elongate slot lengthwise of the tube to form a liquid flow passage, the edges defined by the slot-being sufficiently flexible to permit fluid to pass outwardly therethrough and to close on being subjected to a negative pressure within said tapered tube to permit the development of a high negative pressure therein.
  • This invention relates to surgical drainage apparatus. More particularly, the invention relates to such apparatus including a collection chamber and a drainage tube for placing the container in fluid communication with a cavity to be drained. Still more particularly, the invention relates to such apparatus wherein the collection chamber is maintained under a negative pressure to assist drainage of said cavity. In one aspect the invention relates to a check valve for such apparatus and, in another aspect, to such drainage apparatus including the check valve.
  • Surgical drainage devices are utilized to drain a cavity, such as a pleural cavity.
  • a known device is illustrated in US. Pat. No. 3,559,647 issued Feb. 2, 1971 and incorporated herein by reference.
  • the device therein disclosed includes a collection chamber, an underwater seal chamber, and a pressure regulating chamber.
  • a problem which has arisen in connection with the use of underwater drainage apparatus is in providing means which will permit the patient to develop high negativity in the pleural cavity when such condition is necessary for the patients breathing efforts. 'That is to say, if there is a blockage in the patients bronchial tubes, the patient must make a strong respiratory efiort in order ,to expand the lungs and permit air to flow around this blockage into the lung cavity. In doing this the rib cage is expanded so as to produce a very high negativity in the pleural cavity.
  • prior types of underwater drainage apparatus will defeat such respiratory efforts by permitting the air to be drawn back into the pleural cavity from the drainage apparatus.
  • a surgical drainage system comprising a collection chamber, a drainage tube adapted to place the chamber in fluid communication with a cavity to be drained, and a check valve located in said drainage tube to permit the passage of fluid from said cavity to said collection chamber and to prevent the passage of fluid from said collection chamber to said cavity to permit the development of high negative pressure in said cavity, said check valve being positioned within said drainage tube and comprising an elongate tapered tube the wide portion of said tapered tube being positioned in saiddrainage tube towards said cavity, the narrow portion of said tapered tube being positioned towards said collection chamber, said tapered tube including an elongatedslot lengthwise of the tube to form a liquid flow passage, the length of said slot being at least twice the width of said tapered tube at its widest part, the edges defined by said slot being sufficiently flexible to permit fluid drained from said cavity to pass therethrough and to close on being subject

  • FIG. 1 there is shown an underwater drainage apparatus 10 having a "trap chamber 11, an underwater seal chamber 12 comprising a first column 12a and a second column 12b, and a pressure regulator chamber 13 having a first column 13a and a second column formed in two portions, namely 13b and 13c.
  • the apparatus is completely enclosed except for an opening 14 adapted to be connected to the pleural cavity of the patient by means of tube 14a an opening 15 adapted to be connected to a vacuum source by means of tube 15a and an opening 16 to atmosphere.
  • the main feature of compartment 21 is that it is of a small enough cross section so that the amount of liquid collecting therein can be readily determined in increments of 1 cubic centimeter. In a typical embodiment this compartment will hold 250 cubic centimeters of liquid after which additional liquid will simply flow over the upper portion 20a and into the main portion of the trap chamber 1 l which would normally be designed to hold approximately 3,000 centimeters.
  • Trap chamber 11 is also provided with a solid crossrib designed to strengthen the trap chamber to prevent implosion.
  • This rib 24 separates the bottom of the trap chamber into two parts 23a and 23b. 23a would fill up first after which further liquid would flow over 24 to 23b.
  • the underwater seal chamber 12 is formed by partitions 30, 31 and 32 which form first and second columns 12a and 12b communicating through passage 33 at their lower ends.
  • the device includes a gas flow meter 45 for determining the flow rate of gas passing through the underwater seal chamber- Obviously, for gas to flow upwardly in column 12b, the level of liquid in 12a must be at the bottom thereof.
  • the flow meter comprises a series of openings formed in the web partition member 47;
  • the column 12b includes an enlarged reservoir area 120 to hold the water in the underwater seal in the event of violent bubbling of air through column 12b, as might occur in the case of a very large bronchlpleural fistula.
  • the portion of the apparatus to the left of partitionv 32 represents the pressure regulator chamber 13 having a first column 13a with its upper end exposed to atmosphere and a second column which comprises two portions 13b and 13c, each of which is exposed at its upper end to the pressure at vacuum opening 15.
  • first column 13a with its upper end exposed to atmosphere
  • second column which comprises two portions 13b and 13c, each of which is exposed at its upper end to the pressure at vacuum opening 15.
  • An important feature of the device also includes a meter which clearly and visually shows the rate of airflow upwardly through the second column of the pressure regulator chamber.
  • This flow meter comprises a web partition member extending across the flow meter and having formed therein a plurality of airflow holes 51a, 51b, 51c, and 51d.
  • the upper end of column 13a includes a funnel shaped opening 52 to facilitate placing water into the pressure regulator chamber. There is also formed a relief opening 53 to assure continued communication between column 13a and the atmosphere in the event that the opening 16 becomes obstructed.
  • the basic operation of the apparatus is similar to the basic operation of the apparatus as described in previous US. Pat. Nos. 3,363,626 and 3,363,627.
  • an amount of liquid is introduced into the pressure regulator chamber 13 through opening 16 which will give the desired vacuum after the pump is turned on, and a desired amount of liquid is introduced into the underwater seal chamber 12 through opening 15.
  • Opening 14 is then connected to the pleural cavity of the patient and opening 15 is connected to a vacuum pump.
  • the pump is then turned on gradually as the liquid rises in the second column of the pressure regulator chamber (portions 13b and 13c). As the capacity of the vacuum pump increases, the liquid rises in portions 13b and 13c until all of the liquid is contained in these portions.
  • a further increase in the capacity of the pump will cause air bubbles to be drawn through opening 51a into the portion 13b and hence through the opening 15 to the vacuum pump. Any liquid rising with the bubbles will engage a baffle and fall downwardly. Meanwhile the liquid in the underwater seal chamber may rise in column 12b in which case bubbles will flow upwardly through an opening in member 47 to the opening 15 and hence to the vacuum pump.
  • a check valve is provided in a drainage tube between the cavity to be drained and the collection chamber.
  • the check valve is preferably located close to the cavity to reduce the dead space.
  • a check valve according to the present invention has several additional inherent advantages. For example, the valve opening through which the drained fluids pass is large relative to the size of the drainage tube in which it is placed thus presenting a minimum resistance to fluid flow. Further, the tendency of the valve members to adhere after prolonged use is reduced. This is a particularly severe problemdue to the adhesive nature of the fluids being drained.
  • the opening 64 for the passage'of liquids is large relative to the size of the device and relative to the size of the drainage tube. This is accomplished by providing elongate slot 64 along tapered tube 61 in the manner shown. Slot 64 extends diagonally across the tube in which it is positioned. Preferably, slot 64 extends diagonally across the tube from a point nearthe widest portion of the tapered tube adjacent a wall of the: tube to a point near the narrowest portion of the tube adjacent the tube wall. With reference to FIG. 2, it will be seen that liquid being drained will cause flexible edges 65, 66 to part along the length of slot 64. Therefore, the opening which edges 65, 66 may assume is potentially huge relative to the size of the device and of the drainage tube. It will therefore be seen that by providing the slot 64 in a tapered tube in this manner, it is possible to provide a check valve with reduced resistance to flow.
  • FIG. 2 A check valve according to the present invention is shown in FIG. 2 positioned in a drainage tube 16 connected to collection container10 of FIG. 1. While, in this embodiment, the collection container includes a water seal chamber and operates under suction, it will be apparent that thedevice can be operated without suction, in which case'column 27 of water seal chamber 12 isopento atmosphere. Similarly, the device may be operated without a water seal in which case collection chamber 11 isopen to atmosphere or to a regulated pressure.
  • the surgical drainage system includes collection chamber 11 placed in fluid communication with a cavity to be drained by a drainage tube 16 such as a thoracotomy tube used for draining a pleural cavity.
  • a drainage tube 16 such as a thoracotomy tube used for draining a pleural cavity.
  • Che'ckvalve 60 comprises an elongate tapered tube 61 positionedin drainage tube 16 with its wide portion 62 towards said pleural cavity and its narrow portion 63 towards collection chamber 11.
  • Tapered tube 61 includes an elongate slot 64 lengthwise of the tube to form a liquid flow passage, the length of the slot being at least twice the width of the widest portion 62 of tapered tube 61.
  • edges 65, 66 defined by slot 64 are sufficiently flexible to permit fluid drained from the pleural cavity to pass therethrough and to close on being subjected to low pressure within the tube to permit development of a high negative pressure in the pleural cavity.
  • the edges 65, 66 of tapered tube 61 and the tube wall adjoining those edges are fabricated from conventional elastorn'er rubber, or other flexible material such as silicone rubber.
  • the elongate tube 61 is fabricated from such flexible material.
  • the tube portion 16' is sized to accommodate the outer dimensions of check valve 60.
  • the upper portion of check valve 60 is cylindrical and has the same inside diameter and wall thickness as drainage tube 16.
  • Tube portion 16' is thus cylindrical and has an inside diameter slightly larger than that of the wide portion of check valve 61 and larger than the outside diameter of drainage tube 16.
  • Check valve 60 is conveniently positioned in tube 16 by means of adhesive 68 located around the upper cylindrical portion of check valve 60.
  • Tube 16' is conveniently secured to tube 16 by means of adhesive 69 or I by rubber connectors of the like.
  • the taper of tube portion 61 is offset with respect to a longitudinal axis passing through the wide portion 62 of the tube. This is most easily seen with reference to F IG, 2.
  • the tube is viewed normal to a plane passing through slot 64 and a line lengthwise of the tube at 71 on the tube wall oppos'ite'slot 64.
  • Slot 64 thus extends diagonally across the inside of the drainage tube.
  • slot 64 is a straight line.
  • the slot can be curved such as by providing tube 61 with a non-linear taper.
  • valve slot ex,- tends along the tapered portion of the check valve from a point near the widest point of tapered tube 61 to a point near the narrowest point thereof.
  • Tapered tube 61 is sized to accommodate a slot 64 having a length at least twice the widest portion 62 of the tapered tube. Still more preferably, slot 64 is at least three times as long and is conveniently up to six or more times as long.
  • tapered tube 72 is similar to tapered tube 61 except that the tube is circular in cross section along its length (see FIGS. 7A, B and C) and a longitudinal sealing member 73 is located just inside the slot 74 formed by edges 75, 76 (FIG. 8B) of the tube wall.
  • Sealing member 73 (shown schematically in FIG. 5) is conveniently a cylindrical rod of a rigid material such as plastic, glass; or the like, fixed in position in tube 72 just behind slot 74 in any convenient way such as by being inserted into pockets provided for the purpose in tube 72, by being molded into the tube, or by adhesives or the like.
