Definitions

  • a special pediatric compartment is formed in the trap chamber.
  • the purpose of the present invention is to provide a new an improved underwater drainage apparatus which overcomes problems encountered in the use of previous underwater drainage apparatus.
  • the underwater seal chamber serves several purposes, one of which is to prevent atmospheric air and evacuated gases from passing back into the pleural cavity. Another purpose is to provide a constant pressure head against which the drainage force (either suction applied by a pump and/or positive, pressure in the pleural cavity of the patient during expiramust act. This second purpose is fulfilled by keeping relatively constant the quantity of liquid forming the underwater seal ln our previous Pat. No. 3,363,327, the phenomenon of compliance was discussed.
  • compliance could occur as the patient expanded his pleural cavity by move: ment of his rib cage and his diaphragm muscles) if the lung failed to expand with the cavity, owing to an obstruction in the patients air passage.”
  • Compliance manifests itself in the drainage apparatus by a rapid rise of liquid in the column of the underwater seal chamber adjacent the trap chamber.
  • a reservoir is provided for collecting liquid which rises in this column. Howev er, if this condition persists, bubbles will flow upwardly through the column of liquid and create a spray which will carry a substantial amount of liquid from the underwater seal over to the trap chamber, notwithstanding the provision of an enlarged reservoir at the top of the seal chamber.
  • an arrangement for preventing liquid sprayed upwardly in the underwater seal chamber from carrying over into the trap chamber is provided.
  • this result is obtained by placing a baffle arrangement in the path of the upwardly moving spray to catch the spray and direct the liquid downwardly and by placing the opening to the trap chamber away from the path of the spray.
  • the pressure regulator chamber is often employed to regulate the pressure to be applied on the side of the underwater seal chamber closest to the vacuum pump. For example, assume that it is desired to keep the common space above the leg of the pressure regulator chamber opposite from atmosphere and the leg of the underwater seal chamber opposite from atmosphere and the leg of the underwater seal chamber opposite from the trap chamber at a vacuum of -20 centimeters of water.
  • the pump itself will normally be capable of pulling a vacuum much greater than the desired -20 centimeters so-that the maximum vacuum which the pump is capable of pulling must be reduced to the desired level by the pressure regulator.
  • the pressure regulator chamber is filled with an amountof water such that when all of the water is located in the leg of the pressure regulator chamber closest to the pump, it will be at a height of 20 centimeters. Now the pump is turned on until the liquid in the leg of the pressure regulator chamber closest to the pump, does in fact rise to a level of 20 centimeters. Further pumping capacity will not further increase the vacuum in the said common space. Rather, it will draw air from the atmosphere through the pressure regulator chamber and into the pump. Meanwhile, assuming that the pressure in the pleural cavity is greater than -20 centimeters of water, the liquid in the underwater seal er will also in th o umn openin n o the ommon space.
  • the P i n lykse Esq asset ejtssn sn of gas for example, one cubic foot per minute. If the patients pleural cavity has no leaks to admit air therein the quantity of gas evacuated by the pump will be supplied entirely by the pressure regulator chamber and considerable bubbling will occur in this chamber. However, if a leak exists in the pleural cavity so that air is admitted into the cavity, the underwater seal will bubble and the bubbling through the pressure regulator chamber will be correspondingly reduced. It is important for the physician to know the amount of air leakage into the pleural cavity and also to know that the pump is capable of maintaining a sufficient degree of vacuum within the plueral cavity. Obviously, if the pressure conditions within the pleural cavity approached atmospheric, the patient would be unable to breathe and the physician must be made aware of any such approaching condition.
  • the foregoing problems are met according to the present invention by providing an airflow meter in the pressure regulator chamber and the underwater seal chamber. By reading the degree of bubbling through the underwater seal chamber the physician can determine the precise amount of leakage through the pressure regulator chamber. The physician can then be assured that the pump is maintaining the proper vacuum conditions and that the entire demand of the pump. i.e. one cubic foot per minute, is not being satisfied through the pleural cavity.
  • these flow meters each take the form of a plurality of slots arranged such that as the airflow is increased, the number of slots through which the airflow passes is increased.
  • another feature of the present invention is a bafile arrangement for preventing the water which rises in the pressure regulator chamber from being carried into the pump.
  • this arrangement takes the form of a baffle means located in the path of the stream of bubbles so that the rising water engages the baffle means where it loses its momentum, after which it falls back into the pressure regulator chamber while the gas continues its movement into the pump,
  • the column of the pressure regulator chamber closest to the pump comprises two portions in fluid communication with each other wherein the flow of bubbles is limited to only one of the two portions so that the other remains calm.
  • the level of the liquid in the column of the pressure regulator closest to the pump can then be accurately determined by observing the calm chamber.
  • the trap chamber of the apparatus is provided with a special pediatric compartment having an opening beneath the main inlet to the trap chamber so that liquid entering the trap chamber will first collect in the pediatric compartment.
  • This compartment will be sufficiently small in cross section so that fluid accumulation therein could be measured in increments of one cubic centimeter.
  • This special compartment could be arranged so that after it became full, additional liquid entering the trap chamber would flow to the remaining portion of the trap chamber.
  • FIG. I is a sectional view taken through the center plane of an underwater drainage apparatus constructed according to the present invention.
  • FIG. 2 is a horizontal sectional view taken along line 2-2 of FIG. I.
  • FIG. 3 is a horizontal sectional view taken along line 3-3 of FIG. 1.
  • FIG. 4 is a horizontal sectional view taken along line 4-of FIG. 1.
  • FIG. 5 is a horizontal sectional view taken along line 5-5 of FIG. 1.
  • FIG. 1 would represent one-half of the apparatus wherein the sectional lines represented the surface to be joined to the mating half, and wherein the plain areas represent spaces in the finished apparatus.
  • the apparatus could be constructed with its two large sides as plane surfaces wherein the parts shown in cross section in the drawings would be ribs extending inwardly from the plane sides.
  • the parts shown in cross section in FIG. I are formed as indentations from the outermost sides of the apparatus, which indentations join to form a thin seam between the various chambers along the center plane of the apparatus.
  • the areas between the various chambers will be referred to hereinafter as partitions? Referring now to FIG.
  • an improved underwater drainage apparatus I0 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, an opening I5 adapted to be connected to a vacuum source and an opening 16 to atmosphere.
  • One feature of the present invention includes a pediatric collection compartment formed by partition 20 in the main trap chamber 11.
  • An upper portion 20a of the partition 20 and a drip ledge 22 deflect the incoming liquid into the pediatric collection compartment 21.
  • 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 detennined in increments of one cubic centimeter. In a preferred embodiment of the invention this compartment will hold 250 cubic centimeters of liquid after which additional liquid will simply flow over the upper portion 200 and into the main portion of the trap chamber 11 which would normally be designed to hold approximately 3000 cubic centimeters.
  • Trap chamber 11 is also provided with a solid cross-rib 24 designed to strengthen the trap chamber to prevent implosion.
  • This rib 24 separates the bottom of the trap chamber into two parts 23:: and 23b. 23a would fill up first after which further liquid would flow over 24 to 231).
  • the underwater seal chamber 12 is formed by partitions 30, 31 and 32 which form first and second columns 12a and 12h communicating through passage 33 at their lower ends.
  • a means for preventing liquid surging upwardly in column 12a e.g. during compliance
  • a separation chamber 39 which lies in the path of, and thus is engaged by the upwardly surging column of liquid.
  • the area 35 is spaced from the main portion of column 120 by a partition 37.
  • the upper and lower openings 40 and 38 are inclined downwardly towards the area 35.
  • the flow meter 45 for determining the flow rate of gas passing through the underwater seal chamber.
  • the flow meter comprises a series of openings 46a, 46b, 46c, 46d, formed in the web partition member 47. Of course more openings could be employed if desired. Gas bubbling through opening 46a would indicate a predetermined rate of gas flow. As the gas flow increased, bubbling would be visible through the two openings 46a and 46b. A further increase in the bubbling rate would be indicated by bubbles passing through openings 46a, 46b and 46c. In a like manner additional gas flow would cause bubbling through all four openings 4611 through 46d.
  • opening 46a may represent a loss of 2 liters per minute while flow through openings 46b and 46c may represent an airflow of 4 liters per minute and 8 liters per minute respectively.
  • Air flow through opening 46d would indicated a flow greater than 8 liters per minute. 2 liters per minute is believed to be satisfactory.
  • a loss of 4 liters per minute should be called to the doctor's attention and a loss of 8 liters per minute might well represent an emergency situation.
  • the column 12b includes an enlarged reservoir area 12c 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 bronchopleural fistula.
  • the portion of the apparatus to the left of partition 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.
  • the purpose of the two portions 13b and 136 is two-fold.
  • the main purpose is to confine the bubbles rising through the pressure regulator chamber to the portion 13b so that the liquid rising with the air bubbles will engage a main baffle 53 which will deflect the liquid downwardly into either portion l3h or 134' after which the gas would continue its upward movement to the opening 15.
  • the lower opening 52 connecting the two portions 13! and [3c is directed downwardly between lower edge 50a of a partition 50 and a lower ledge 51.
  • portions 13b and 13c will tend to seek the same level, the bubbles will be confined to portion 13b.
  • Another feature of the two portion arrangement is that it provides a calm portion 13c exposed to the same pressure as 13b but relatively clam as compared to portion 13b. Consequently, the level of liquid in the second column of the pressure regulator chamber 13 can be readily determined by noting the level of liquid in portion 13c.
  • baffle 53 In the event that some liquid does flow upwardly pass baffle 53, it will be engaged by a second baffle 54. Further upward flow of water is caught by a series of drip ledges 55a, 55b and 556.
  • this flow meter 60 which clearly and visually shows the rate of airflow upwardly through the second column of the pressure regulator chamber.
  • this flow meter 60 comprises a web partition member 61 extending across the flow meter and having formed therein a plurality of airflow holes 62a, 62b, 62c and 62d.
  • the number, shape and/or size of the holes would depend upon the desired operating characteristics of the flow meter. A given force would be necessary to draw air through the hole 62a. A greater force would increase the volume of airflow so that bubbles passed through hole 62b as well as 62a.
  • the volume of airflow would increase until it flowed through openings 62cas well as opening 62a and 62b.
  • still a greater force would cause further increase in the volume of airflow so that the air passed through all four openings including opening 62d.
  • the openings could be designed to represent onefourth, one-half, threequarters and one cubic foot of airflow per minute. With this arrangement it would be possible merely by observing the airflow meter, to determine which portion of the total air passing to the vacuum pump through opening 15 is derived from the pressure regulator chamber 13 and which portion is derived from the pleural cavity through the underwater seal chamber 12.
  • the upper end of column 13a includes a funnel shaped opening 66 to facilitate placing water into the pressure regulator chamber. There is also formed a relief opening 65 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 10 is similar to the basic operation of the apparatus as described in our previous Pat. Nos. 3,363,626 and 3,363,627.
  • the features of the present invention have not changed the basic operation of the apparatus. Rather, they have been designed for the purpose of increasing the efficiency, controllability and applicability of this type of apparatus.
  • the effect that each of these individual features has on the basic operation is believed to be clear from the above description of the various features. However, for purposes of convenience, the operation of the invention will be briefly summarized at this point.
  • 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 131; and 13c).
  • portions 131; 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 62a into the portion 13b and hence through the opening 15 to the vacuum pump. Any liquid rising with the bubbles will engage baffle 53 and fall downwardly. Meanwhile the liquid in the underwater seal chamber may rise in column 12b in which case bubbles will flow upwardly through opening 46a to the opening and hence to the vacuum pump.
