Definitions

  • the invention relates to drainage of air and fluid from the thoracic cavity after thoracic surgery.
  • An alternative flutter valve drainage system (Portex Ltd) has beens hown to have several advantages over the underwater seal system. This uses a bag with a flat valve with straps pulled across a patient's chest.
  • the flutter valve drainage bag was found to be safe and effective in the post-operative situation and permitted earlier mobility. Also, the system maintains a more negative intrapleural pressure during tidal respiration without suction.
  • the flutter valve drainage bag does however have some disadvantages in that suction cannot be applied to the collapsible bag and therefore the bag cannot always be used immediately after surgery. Patients are therefore immobilised for several days postoperatively until suction can be removed.
  • a portable device for the collection of thoracic fluid comprising a collection chamber having an inlet for connection to a patient, a one-way valve that permits passage of thoracic fluid from the patient to the collection chamber through the inlet, and a portable suction unit that also co-operates with the collection chamber for evacuation of air thereform.
  • the invention uses a flutter valve rather than an underwater seal with advantages as set out about-G.
  • the container is rigid and therefore suction can be applied.
  • the portable suction unit is battery powered. This enables the patient to mobilise earlier.
  • the collection chamber and the suction unit are each of a size and weight that allow them to be carried by a patient.
  • the one-way valve, the inlet and the connection of the chamber with the suction unit are disposed on a removable lid of the chamber.
  • the lid of the container has at least two valves, one of which can be used for the evacuation of air from the container, the other valve allowing collection of thoracic fluid.
  • a conventional intercostal drainage tube can be connected directly to the unit.
  • the flutter valve is already established in clinical practice.
  • a negative suction control can be used to prevent suction greater than 5KPa.
  • a positive pressure release valve can prevent complications from system occlusion.
  • An audible plus visual indicator of low battery power on the portable suction unit can be used.
  • the size (500ml capacity) and wieght of the units allow to be positioned on the hip to permit complete mobiity.
  • Figure 1 illustrates a device according to the invention.
  • Figure 2 illustrates pump pressure with a conventional underwater drawin to validate pressure monitoring.
  • Figure 3 illustrates pump pressure in the device of the invention demonstrating that suction works.
  • FIG. 4 illustrates pump pressure in the device of the invention.
  • the MIS thoracic drainage bottle and portable suction unit is comprised of three elements :-
  • Collection chamber - the collection chamber (1) will be available in 0.51tr and 0.251tr versions with 20ml graduations (2) .
  • the shape of the chambers will be curved, as can be seen from Figure 1, to allow ease of placement on a patients hip.
  • the chambers will be rigid allowing suction levels of up to -40cms H 2 0 to be applied.
  • a clip (3) is attached to the rear of the chamber to enable a belt to be passed through it.
  • the lid section contains the working elements of the unit and is compatible with both sizes of container.
  • Portable suction unit (21) - the portable suction unit is also secured via the patient belt (4) and attached to the MIS thoracic drainage bottle via a short length of tubing.
  • the unit is battery operated, re-chargeable, having a working cycle of 18 hours between charges.
  • suction is applied the patient remains mobile by using the portable suction unit.
  • the patient is conventionally confined to a bed when wall suction is applied to the traditional drainage units, and if a drainage bag is being used it will have to be removed and replaced with a rigid unit, before wall suction can be applied.
  • MIS thoracic drainage unit After thoracic surgery, if a patient wants to be mobile, but large drainage containers or bags are being used for drainage these devices often pull and agitate the surgical wounds due to carrying arrangements and straps. If the MIS thoracic drainage unit is used its position on a belt on a patient hip provides no such inconvenience.
  • Figure 3 demonstrates that suction works on the system as suction pressure moves from lOppm (3A) to 2ppm (3B) .
  • the system is opened to air (3C) and the portable suction unit is introduced (3D) and switched off (3E) and on again (3F) .
  • Figure 4 demonstrates that the addition of water to visual air flow indicator does not impair function (4A) , that portable suction works (4B) and that "blow- out" valve works when system is occluded (4C) .

Abstract

L'invention concerne un dispositif portatif pour collecter le fluide thoracique. Ce dispositif comprend une chambre de collecte (1) comportant une entrée (16) prévue pour être reliée à un patient, une vanne à une voie (11) qui assure le passage du fluide thoracique du patient à la chambre de collecte (11) par l'entrée (16), et une unité d'aspiration portative (21) qui coopère avec la chambre de collecte (1) pour assurer l'évacuation de l'air de cette dernière. De préférence, la vanne à une voie (11), l'entrée (16) et le raccordement de la chambre (1) sont placés sur un couvercle amovible de la chambre (1). La chambre de collecte (1) et l'unité d'aspiration (21) présentent un poids et une taille qui leur permettent d'être portés par le patient.
