Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing. In some embodiments, the pump apparatus includes components configured to be laser welded together.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes applying a drive signal to a pump assembly of the pump system, the drive signal alternating between a positive amplitude and a negative amplitude and the drive signal having an offset, and sampling a pressure within a fluid flow path configured to connect the pump system to a wound dressing configured to be placed over a wound during one or more time intervals. Each of the one or more time intervals can occur when the drive signal is approximately at an amplitude equal to one or more sampling amplitudes.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.

Waste disposal devices and methods are provided. The device includes a housing, a lid, a bucket frame, a pair of members, and a foot pedal. The foot pedal is operatively associated with the lid and the pair of members so that the lid is in the closed position and the pair of members is in the non-use position when the foot pedal is in the upper position. Further, the foot pedal is operatively associated with the lid and the pair of members so that the lid is in the open position and the pair of members is in the use position when the foot pedal is in the lower position.

Systems and methods for controlling and/or calibrating a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes calculating an amplitude and an offset for a drive signal based at least in part on previously calculated parameters and a negative pressure setting, generating the drive signal, and applying the drive signal to a pump system. The pump system can be fludicially connected to a wound dressing positioned over a wound.

There is provided a sealing apparatus for forming void-fill packaging which includes a longitudinal guide path along which an edge of a part-sealed plastics film material can pass, a drive means for moving the film material along the guide path, and an air blowing or injecting means for inflating the film material. There is also provided a heating element and a rigid thermally conductive member which is thermally coupled to the heating element, the thermally conductive member having an film-contacting surface for applying thermal energy to seal the film material on the longitudinal guide path.

[Object] Provided is a tube joining device which is capable of preventing occurrence of a joining failure caused by a setting error of tubes in advance, and in which tube holding and release of the holding are realized by a simple device configuration.

[Solving Means] A tube joining device 1 includes: a first tube holding portion 160 that is capable of holding a first tube T1; a second tube holding portion 230 that is capable of holding a second tube T2; a tube superimposing portion 30 that disposes the first tube and the second tube in a superimposed manner; and a switching mechanism 240 that is capable of switching holding of the second tube by the second tube holding portion and release of the holding. The switching mechanism applies a biasing force for maintaining a state in which the second tube is held to the second tube holding portion, and applies a biasing force for maintaining a state in which the holding of the second tube is released to the second tube holding portion in accordance with relative approaching of the tube holding portions.

A station for sealing thermoformed containers for a packaging line and a method for sealing the containers includes a sealing carousel which rotates continuously about a central axis and includes sealing heads which are radially spaced apart from said central axis. Each sealing head is adapted to receive at least one container to be sealed at a first, input, peripheral region, which is outside the sealing carousel; receive at least one closing seal at a second, input, peripheral region, which is outside the sealing carousel; and hold the closing seal and the container during the rotation of the sealing carousel and couple them together.

The station further releases the container complete with the closing seal at a third, output, peripheral region, which is outside the sealing carousel and angularly spaced from the first and from the second region.
