Suction Drainage System

TCS System Description

  • The TRU-CLOSE Suction Drainage System is designed to be a completely closed system for abscess and other fluid drainage.
  • Compact and self-contained system allows full patient ambulation.
  • During activation, body fluids are not aerosolized because all fluids are contained in the system.
  • Closed system design reduces the chances of cross-contamination.
  • Dual anti-reflux valves prevent liquids and air from backing up into the catheter or wound drain.
  • All TCS bags come with a standard luer lock connector to fit all luer-locking drainage catheters.
  • In addition to the standard luer lock connector, the TCS300D comes with two straight connectors to be used with post surgical wound drains.
  • If the bellows fills, flow to the bag continues via gravity drainage as long as the bag is below the level of the drainage site.
  • Bag sizes: 300, 500 and 1,000 ml.
  • Available with empty port in the 300 ml and 500 ml sizes.

Patient and Nursing Information

  1. To adjust the tubing length, remove the tube from the top of the housing or pull off the luer lock connector and cut the tube with a scissors to the desired length (see Figure 1).
  2. To change the luer lock connector to a straight connector for use with a silicone wound drain, cut the tube or remove the adapter and insert the desired connector (see Figure 2).
  3. If the bag comes with an empty port, twist it closed (see Figure 3). 
  4. Attach the bag to the drainage catheter or wound drain.
  5. To ensure continous flow, attach the bag to the patient gown or bedding below the level of the drainage site.  
  6. To activate the system, compress the bellows completely (see Figure 4). Do not try to pump the bellows; it will fill as it draws fluid from the drainage site. If the bellows is not re-activated after filling, the system will convert to gravity drainage thus preventing fluid backup.
  7. To re-activate the system, compress the bellows. The fluid in the bellows will be discharged into the bag and the suction will be re-established (see Figure 4).
  8. The bag is strong enough to withstand a build up of air pressure within the bag. The bag is equipped with hydrophobic filter vents, which will vent collected air. Air can be manually forced out of the bag by gently squeezing the bag while the system is positioned vertically (housing above bag).
  9. Although the graduation marks on the bag are approximations only, approximate volumes collected can be recorded on the white "write-on" area on the bag. When recording these approximations, first empty bellows contents into the bag.

Thora Vent

Pneumothorax Kit

Thora-Vent Thoracic Vent Description:

  • The Thora-Vent Thoracic Vent is the first totally contained device that gives the doctor and patient more flexibility in treating spontaneous, traumatic, or iatrogenic, simple pneumothorax.
  • All the components necessary for immediate insertion and evacuation are completely contained in one simple tray
  • The resolution of a pneumothorax is possible anywhere, anytime.

Why is it used?

  • To treat simple pneumothorax.
  • It is small, self contained and attaches firmly to the chest.
  • It allows freedom of movement and thereby reduces the complications of immobility.
  • The one-way valve is permanently attached to the catheter.
  • When the pressure in the pleural space is greater than + 2 mm Hg the red signal diaphragm deflects upward. The pneumothorax may be resolved when the red signal diaphram stays down (intrapleural pressure less than -2 mm Hg) and the patient is asymptomatic.

Instructions for Use

{Abbreviated - see package insert for detailed instructions.}

  1. Recommended insertion site - second interspace midclavicular line.
  2. Make a small skin incision at the insertion site.
  3. Load the trocar into the catheter.
  4. Remove the paper strips from the center portion of the device to expose the adhesive.
  5. As the trocar/catheter assembly is introduced, stay immediately above the superior border of the rib.
  6. The red signal diaphragm will deflect upwards when the tip of the catheter enters the pleural cavity. When this occurs, stop advancing the trocar and advance the catheter. The red signal diaphragm will then continue to fluctuate with respiration as the intrapleural pressure varies from > +2mm Hg to < -2mm Hg. When the signal diaphragm stays in the down position and the patient is asymptomatic, the pneumothorax may be resolved.
  7. Remove the trocar. Do not reintroduce the trocar unless the catheter is completely removed from the patient.
  8. Peel away the paper on the side flaps to expose the adhesive. Adhere the device. The suture holes on the top of the device can be used for additional fixation.


Catalog number TV11-13 can be inserted over-the-wire using the separately provided insertion cannula (catalog number OTW11-13).

Manual Aspiration of Air

The aspiration cannula and 60cc syringe can be used to manually aspirate air from the pleural space. Cap the self-sealing port with the tethered cap after aspirating.

Manual Removal of Liquids

If small amounts of naturally occurring fluid accumulate in the device, the fluid can be aspirated via the drainage port at the bottom of the device using a syringe.

Continuous Air Leak Check

The occlusion plug can be inserted into the self-sealing port to occlude the catheter in order to check for a continuous air leak. The Thoracic Vent will not vent air when this plug is in place, so remove it immediately after the check is completed. Cap the port with the tethered cap after the check.

External Suction

The device can be attached to external suction using the suction tubing set. Prior to attaching the suction tubing set, close the clamp. Insert the cannula into the self-sealing port and lock it in place. Attach the funnel end to an appropriate suction system and open the clamp. Do not exceed 20 cm water vacuum. When the suction tubing set is removed from the Thoracic Vent, cap the port with the tethered cap.


  1. Do not rotate the trocar during introduction through or removal from the self-sealing port.
  2. Do not reinsert the trocar unless the catheter is completely removed from the patient.
  3. Difficult Catheter Removal. If the catheter is inadvertently introduced through the rib periosteum or the trocar is re-introduced after placement of the catheter in the chest wall, the catheter may be damaged and locked within the patient. Removal of the catheter should be unresisted. If resistance is encountered, the catheter may be restrained. It is recommended that a restrained catheter be released by direct surgical intervention or by cutting the catheter from its proximal attachment to the device, securing it and percutaneously passing dilators over the catheter until it is released from its attachment.
  4. This device is not indicated for hemothorax or other liquid drainage. The device can accomodate small amounts of liquid (5cc) but larger amounts can affect device function.
  5. Maintain a proper seal to prevent subcutaneous emphysema.
  6. In the case of a tension pneumothorax, multiple Thoracic Vents or a chest tube might be required.
  7. Continuous drainage of air over extended periods should alert a consideration for additional interventional treatment.
  8. Be aware of complications associated with the treatment of pneumothorax including re-expansion and laceration of intercostal vessels.
  9. Always clamp the suction tubing set when the suction is not being applied.
  10. Do not disinfect the Thoracic Vent with alcohol (propanol). Alcohol will degrade the Thoracic Vent.
  11. If the occlusion plug is used to perform an air leak check, remove the plug after the check is completed. The Thoracic Vent will not vent air when the plug is in place.

Removal of the Thoracic Vent

  1. When the red signal indicator stays in the down position and the patient is asymptomatic, there is a good likelihood that the pneumothorax is resolved. Take an X-ray to confirm resolution of the pneumothorax.
  2. The occlusion plug can be used to seal off the catheter and check for a continuous leak.

Nursing Instructions

  1. Avoid direct contact with water.
  2. Notify the physician if accumulation of excessive blood or other fluid is observed in the device.
  3. Small amounts of fluid can be removed via the syringe-activated port at the bottom of the device.
  4. If skin irritation is observed, notify the physician.
  5. When access to the self-sealing port is not needed, cap it with the tethered cap.
