Definitions

  • Surgical suction devices are primarily used in such medical procedures as cardiotomy operations and the like, which are serious operations involving a heavy loss of blood.
  • a surgical suction device is used to keep the operating field clear of blood, and thus visible to the surgeon.
  • the blood is recycled through the suction device into a socalled cardiotomy reservoir, which serves as a blood storage and filtering means, so that the blood may be re-infused to the patient during or after the operation. This reduces the amount of donated blood which has to be administered to the patient.
  • Membrane and bubble type blood oxygenators are used in many of the major surgical procedures in which surgical suction is used and the sucked blood is recirculated.
  • the hemolysis reduction in these oxygenator devices has advanced to the point where the hemolysis of blood in the surgical suction apparatus has become a significant percentage of the total hemolysis of blood during the entire operation.
  • sparkforming electrical connections anywhere in the vicinity of the surgical field, because of the presence of the pure oxygen being administered to the patient. Additionally, protection must be made against leakage of electrical current, since the device may be in contact with the heart, which can be fibrillated by even very low electrical stimulation. Furthermore, all of the equipment in the vicinity of the surgical field is desirably sterilizable and disposable, for maximum protection against infection.
  • This invention provides a device which avoids the above disadvantages, and provides a conveniently operable, disposable device for controlling a surgical suction pump from a location adjacent the suction tip in the surgical field, without requiring electrical equipment in the surgical field area.
  • the pressure varying means communicates with the pressure responsive pump control means for actuating the suction pump upon sensing a first pressure level and for shutting the pump off upon sensing a second pressure'level.
  • a pressure conduit generally provides the communication described above.
  • FIG. 4 is a schematic circuit diagram of the power and control unit of FIG. 1.
  • FIG. 5 is a fragmentary perspective view of the sucker portion of a modified version of the device of FIG. 1.
  • FIG. 6 is a fragmentary perspective view of the sucker portion of another modified version of the device of FIG. 1.
  • Tip 10 is carried on a suction tube 12, typicaily made of steel, which, in turn is carried by handle 14 with which the operator can grasp the device.
  • Suction tip 10 and tube 12 constitute an extension of suction line 16, which communicates with tube 12 at the rear of handle 14, and is generally made of flexible, plastic tubing.
  • Suction line 16 is shown to comprise an enlarged section 18, which fits in the track of a conventional medical roller pump and motor 20, such as is commercially available from Sarns, Inc. of Ann Arbor, Mich. Accordingly, the operation of the roller pump and motor 20 provides suction within line 16, tube 12 and tip 10.
  • Blood which is expelled past roller pump 20 typically passes in line 22 to a cardiotomy reservoir 24, which is a commercially available item. There, the blood is filtered and stored until the surgeon determines to reinfuse the blood to the patient through line 26. Air which is pumped into reservoir 24 by pump and motor is vented through port 25.
  • a control means for pump and motor 20 is provided so that it can be easily actuated and shut-off as often as desired, to prevent hemolysis ofthe blood in blood lines or conduits l6 and 22, for example, and to prevent the creation of microbubbles of air and small clots, which are not easily filtered.
  • FIG. 3 shows conduit 32 as conventionally connected to control unit 30, in fluid flow communication with internal flow tube 44, which communicates with pressure switch 42 for the actuation thereof.
  • Conduit 34 is likewise conventionally connected to flow tube 46 within control unit 30, which, in turn, is connected to the output of a simple fluid pump 48.
  • the pump can be an inexpensive, commercially available vibratory air pump for an aquarium, manufactured by the Metaframe Corporation of Maywood, NJ.
  • normal line alternating current (approximately I 10 v.) is provided to conductor lines 50 and 52, which may each be connected to opposite terminals of plug and cable 31.
  • Lines 50 and 52 provide an operating circuit for air pump 48, for continuous operation of the pump, while the circuit is energized.
  • Line 54 connects plug 31 to ground.
  • Rectifier diode 56 is provided in line 52 to cut the electrical current received by pump 48 by one-half wave per cycle, so that the electrical power received by the pump is reduced to a value desired for use in the specific device shown herein. This arrangement permits the use of an inexpensive, off-the-shelf pump, rather than an especially made pump of the desired power.
  • Triac 67 controls the power current flowing between lines 66 and 69.
  • Switch 42 controls the action of triac 67.
  • Triac 67 only shuts off when switch 42 is opened and the current flow through triac 67 is zero, which occurs twice per cycle with conventional alternating current as is used here.
  • Line 68 provides electrical communication through cable 28 between triac 67 aand plug 70.
  • Line 68 connects through plug 70 with a terminal of pump motor
  • Light 74 is energized when triac 67 is in open mode, since, under those circumstances, approximately a 110 volt potential exists between opposite terminals of triac 67, anti between lines 58 and 68.
  • light 74 functions as a power light, indicating the readiness of the device to operate.
  • a suitable pump 48 can be arranged to provide suction to conduits 34 and 36 rather than pressure, and the fluid communication arrangement to the pressure switch 42 can be appropriately modified with a diaghragm means or the like so that the pressure switch is actuated to permit current flow upon the sensing of a reduced pressure rather than an increased pressure.
  • a diaghragm means or the like so that the pressure switch is actuated to permit current flow upon the sensing of a reduced pressure rather than an increased pressure.
  • conduits 34, 36 could thus be somehow plugged, and accordingly pump motor 20 would continuously operate, and could only be shut off by deenergizing the circuit.
  • a circuit can be easily designed in which the pump motor ope rates only when the pressure switch 42 is in the of position, rather than the on position. This might be conveniently utilized in conjunction with the mode in which suction is provided to conduits 34, 36, rather than a positive pressure.
  • this embodiment can operate automatically, to keep a fluid level as low as desired.
  • a surgical suction pump in which the blood suction motor can be started and turned off by simple manual manipulation from a location near the suction tip, or by other pressure responsive means, without the use of electrical componentry near the surgical field.
  • the improvement of this invention can be used to substantially reduce the hemolysis of blood during the surgical operation, and disposable components can be used near the surgical field, for greater patient safety and more rapid recovery.
  • a surgical suction device which comprises a tubular suction member having a suction tip, and a mechanically-operated blood suction pump
  • pressure responsive pump control means for actuating said suction pump upon sensing a first pressure level, and for shutting said pump off upon sensing a second pressure level
  • a pressure conduit other than said suction member, communicating with said pressure responsive pump control means for providing pressure for sensing by said control means, said pressure conduit extending to a position adjacent said suction tip; and means for varying and controlling, from a position adjacent said suction tip, the pressure within said pressure conduit to correspondingly control the operation of said suction pump.
  • said pressure controlling means comprises a suction source communicating with said pressure conduit, and a manually obstructablc aperture communicating with the exterior in said pressure conduit adjacent said suction tip, whereby obstruction of said aperture causes a reduction of the pressure in said pressure conduit, to actuate said pump control means to operate said pump, and removal of said obstruction causes said pressure to rise back toward essentially ambient pressure, to actuate said pump control means to shut said pump off.
  • said pressure control means comprises a squeeze bulb connected to an aperture of said pressure conduit adjacent said suction tip, said pressure conduit being pneumatically sealed from the exterior, whereby manual pressure on said squeeze bulb elevates the pressure in said pressure conduit, to actuate said pump control means to operate said pump, and removal of said manual pressure on said squeeze bulb causes pressure to fall back to essentially ambient pressure, actuating said pump control means to shut said pump off.
  • said pressure control means comprises a source for providing pressurized gas to said pressure conduit, said pressure conduit being essentially co-extensive with said suction tip and having an open aperture positioned next to said suction tip, whereby immersion ofsaid suction tip and open aperture to a predetermined depth into a pool of liquid to be removed by suction will create a liquid pressure head against said open aperture, to correspondingly elevate the pressure within said pressure conduit, to actuate said pump control means to operate said pump, while lowering of said liquid pressure head causes the gas pressure in said pressure conduit to be reduced, actuating said pump control means to shut said pump off.
