Indications for Use

The Tzoar Negative Pressure Wound Therapy (NPWT) System is indicated for wound management via the application of negative pressure to the wound by the removal of wound exudate, infectious materials, and tissue debris from the wound bed. The Tzoar 207 Negative Pressure Wound Therapy (NPWT) System is indicated for the following wound types: chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic or pressure), flaps and grafts.

Device Story

Tzoar 207 NPWT System is a portable, battery-powered suction pump used with specialized dressings (foam kits or one-piece) to manage wounds. Device applies continuous or intermittent negative pressure (40-200 mmHg) to the wound bed to remove exudate, infectious material, and tissue debris, promoting healing. Operated by healthcare providers or patients in clinical or home settings. User programs pressure settings via pump interface. Output is a negative pressure environment maintained at the wound site. Clinical benefit includes wound bed preparation and exudate management. System includes a canister for fluid collection.

The Tzoar 207 NPWT pump is a portable, battery powered pump which may promote wound healing through the drainage and removal of wound exudates, {4}------------------------------------------------ infectious material, and tissue debris from the wound bed using continuous and/or intermittent negative pressure. The Tzoar NPWT One Piece Dressing and the Tzoar NPWT Foam Kits are both Tzoar Wound Dressings intended to be used with an NPWT device to manage acute and chronic wounds. Patients with chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, diabetic ulcers, neuropathic ulcers, pressure ulcers, flaps and grafts may benefit from this system. The Tzoar 207 NPWT pump and Tzoar Wound Dressings are able to produce a negative pressure environment in either Continuous or Intermittent Mode. This allows the user to program the specific pressure ranges. In Continuous Mode, the pressure is ranged from 40mmHg to 200mmHg. In Intermittent Mode, the pump will alternate between the up pressure for 5 continuous minutes and down pressure for 2 minutes. The up pressure can be selected between 40 and 200mmHg while the down pressure can be selected between 20 and 120 mmHg. The pressure is applied to the wound as long as the pump is powered on the previous settings. The factory default is 125 mmHg in Continuous Mode, unlocked. #### Indication for Use: The Tzoar 207 Negative Pressure Wound Therapy (NPWT) System is indicated for wound management via the application of negative pressure to the wound by the removal of wound exudate, infectious materials, and tissue debris from the wound bed. The Tzoar 207 Negative Pressure Wound Therapy (NPWT) System is indicated for the following wound types: chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic or pressure), flaps and grafts. ### Contraindications: The Tzoar 207 NPWT System should NOT be used in the following conditions: - . Exposed vessels, organs, or nerves. - Anastomotic sites. - Exposed arteries or veins in a wound. ● - Fistulas, unexplored or non-enteric. - Untreated osteomyelitis. - Malignancy in the wound. - Excess amount of necrotic tissue with eschar. - Wounds which are too large or too deep to be accommodated by the dressing. ● - Allergy to urethane dressings and adhesives. {5}------------------------------------------------ - Use of topical products which must be applied more frequently than the dressing change . schedule allows. ### Technological Characteristics: The manufacturer believes that the technological characteristics of the Tzoar 207 Negative Pressure Wound Therapy (NPWT) System are substantially equivalent to those of the predicate device. The Tzoar 207 NPWT System has similar components to its predicate device and has similar principles of operation. The Tzoar 207 NPWT Pump consists of an electrically generated source of vacuum and a canister. Like the predicate, vacuum, is applied for a specified period of time and intensity, according to the physician's prescription. Both Tzoar NPWT Foam Kits and Tzoar NPWT One Piece Dressings are alternatively used together with the Tzoar 207 NPWT pumps. The Tzoar NPWT Foam Kits and Tzoar NPWT One Piece Dressings use similar components and similar principles of operation to the predicate device. Like the predicate, the foam is placed into the wound and attached to a vacuum device to provide negative pressure to the wound site to promote healing by removing wound exudates. ### Performance Tests To verify that the device design meet its function and performance requirements, samples of the device underwent function and mechanical testing. | Test Report No. | Test Report Title | |-----------------|-------------------------------------------------------------------------| | TR27.0006 | Tzoar 207 NPWT Canister Presence Sensor Test Report | | TR27.0007 | Tzoar 207 NPWT Canister Hook Test | | TR27.0008 | Tzoar 207 NPWT Canister Air-Tightness Test | | TR27.0010 | Tzoar207 NPWT Canister Air filter water resistance verification Test | | TR27.0011 | Tzoar 207 NPWT Canister Solidifier Expansion Parameter Test Report | The following tests were conducted: {6}------------------------------------------------ | TR27.0013 | Tzoar 207 NPWT System Pressure Accuracy Test Report | |-----------|------------------------------------------------------------------------| | TR27.0014 | Tzoar 207 NPWT System Air Flow Rate Test | | TR27.0025 | Tzoar 207 NPWT System performance test with One Piece Dressing Test | | TR27.0027 | Tzoar 207 NPWT System Performance test with Foam Kit | | TR27.0032 | Tzoar 207 NPWT System Battery Life Test Report | | TR27.0033 | Tzoar 207 NPWT System Battery Performance Testing Report | The conclusions drawn from the performance tests demonstrate that the device is performing as intended and is substantially equivalent to the predicate. ## Biocompatibility Biocompatibility tests were conducted according to the following standards: - .
