Negative pressure wound treatment device, and methods
A negative pressure (i.e., vacuum or suction) wound healing device and system incorporating the device. The device of the present disclosure is smaller, lighter, portable, and overall more manageable by both the user and the medical personnel than the conventional systems. The device could be readily worn by the user.
1. A system for applying negative pressure on a wound, the system comprising:
a device including a housing configured to be mounted on a person, the housing including an instrument panel having a display screen, a top surface, a bottom surface, a first side, a second side, a back side, and a front side, wherein an input line and a drain each extend from the bottom surface;
a flexible container disposed within the housing of the device for storing exudate obtained by the applied pressure on the wound;
a pump configured to provide negative pressure on the wound via the input line;
a dressing material sealably covering the wound, wherein the dressing material is disposed between a spray-in foam and a top layer and wherein the dressing material, via a plurality of holes, is configured to diffuse the negative pressure against the spray-in foam while maintaining a seal between the patient and the dressing material via the top layer, the input line extending between the pump and the dressing material to provide negative pressure to the wound sealably covered by the dressing material;
the spray-in foam located within the wound below the dressing material, the spray-in foam exposed to the negative pressure provided by the pump; and
a first sensor configured to monitor the wound, wherein the first sensor is an infection sensor.
2. The system of claim 1 , further comprising a second sensor configured to monitor the wound, wherein monitoring the wound further includes measuring a parameter of the wound.
3. The system of claim 2 , wherein the parameter is one of temperature, blood pressure, blood flow, O2 level, pH, and pulse rate.
4. The system of claim 1 , further comprising a second sensor configured to monitor the wound, wherein the second sensor is configured to monitor a healing rate of the wound.
5. The system of claim 1 , wherein the infection sensor includes a reagent, the reagent configured to change from a first state to a second state in response to exposure to infected exudate.
6. The system of claim 5 , wherein the change from the first state to the second state includes a change from a first color to a second color.
7. The system of claim 1 , further comprising a second sensor, wherein the second sensor is a pressure sensor, the pressure sensor configured to monitor the pressure at the wound.
8. A system for applying negative pressure on a wound, the system comprising:
a device including a housing configured to be mounted on a person, the housing including an instrument panel having a display screen, a top surface, a bottom surface, a first side, a second side, a back side, and a front side, wherein an input line and a drain each extend from the bottom surface;
a flexible container disposed within the housing of the device for storing exudate obtained by the applied pressure on the wound;
a pump configured to provide negative pressure on the wound;
a dressing material sealably covering the wound, wherein the dressing material is disposed between a spray-in foam and a top layer and wherein the dressing material, via a plurality of holes, is configured to diffuse the negative pressure against the spray-in foam while maintaining a seal between the patient and the dressing material via the top layer, the input line extending between the pump and the dressing material to provide negative pressure to the wound sealably covered by the dressing material;
a plurality of vacuum lines extending between the pump and the dressing material to provide negative pressure to the wound sealably covered by the dressing material; and
at least one sensor configured to monitor the wound, wherein at least one of the sensors is an infection sensor.
9. The system of claim 8 , wherein monitoring the wound further includes measuring a parameter of the wound.
10. The system of claim 8 , wherein the plurality of vacuum lines includes a first vacuum line and a second vacuum line, the first vacuum line configured to provide a first level of suction force and the second vacuum line configured to provide a second level of suction force, the first level of suction force being greater than the second level of suction force.
11. The system of claim 8 , wherein a first sensor of the at least one sensor is configured to monitor a healing rate of the wound.
12. The system of claim 11 , wherein the infection sensor is configured to detect an infection of the wound, and wherein the infection sensor includes a reagent, and the reagent configured to change from a first state to a second state in response to exposure to infected exudate.
13. The system of claim 12 , wherein the change from the first state to the second state includes a change from a first color to a second color.
14. A system for applying negative pressure on a wound, the system comprising:
a device including a housing configured to be mounted on a person, the housing including a pump configured to provide negative pressure on the wound via a vacuum line, the housing including a top surface, a bottom surface, a first side, a second side, a back side, and a front side, wherein the vacuum line and a drain each extend from the bottom surface, wherein the device includes an instrument panel on the top surface, wherein the instrument panel includes a display screen, and wherein one of the first side, second side, front side, and back side includes a concave portion contoured to fit a person's torso;
a dressing material sealably covering the wound, wherein the dressing material is disposed between a spray-in foam and a top layer and wherein the dressing material, via a plurality of holes, is configured to diffuse the negative pressure against the spray-in foam while maintaining a seal between the patient and the dressing material via the top layer, the vacuum line extending between the housing and the dressing material to provide negative pressure to the wound sealingly covered by the dressing material;
a flexible container disposed within the housing of the device for storing exudate obtained by the applied pressure on the wound;
the spray-in foam located within the wound below the dressing material, the spray-in foam exposed to negative pressure provided by the device; and
at least one sensor configured to monitor the wound, wherein the at least one sensor is an infection sensor.
