The present patent specification provides a medical device including an outer tube, an operation portion and a control portion. The operation portion is at least partially located in the outer tube. The control portion has a channel communicating with the outer tube along a first direction; a second end of the control portion is coupled with a first end of the outer tube so that the channel and the outer tube communicate with each other along the first direction. The control portion includes a control module including a suction control unit, a suction, a suction valve actuator and a switching unit. The suction control unit has a stopping unit and is configured to move along a second direction which is different from the first direction. The suction valve actuator is located at a side opposite the suction control unit with the channel therebetween and the suction valve actuator is configured to be activated by the suction control unit. The switching unit is configured to switch the work status of the operation portion.

A device and a method for a lavage-type introduction of a stool transplant or of another, local or topically effective substance through the anus into the colon of a patient, wherein the substance to be introduced is flushed also into the upper parts of the colon of the patient in a torrent-like manner through correspondingly large-lumen catheters; said device comprises an ano-rectal placed head part remaining inside the patient from the beginning until the end of the application and a system of exchangeable bags, which are connectable to the head part, whereby two different types of bags can be applied, one of which is designed for the cleaning lavage, while the another is designed for the introduction of a substance or a transplant.

In some embodiments, a wound dressing includes at least one motion sensor for sensing a motion related parameter associated with motion of the wound dressing; and at least one further sensor for sensing a healing related parameter associated with wound healing at a region of tissue of a wound or proximate a wound covered by the wound dressing.

A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure wound therapy apparatus can include a wound dressing, a negative pressure source, and a controller. The negative pressure source can provide negative pressure via a fluid flow path to the wound dressing. The controller can monitor a rate of fluid removal from the wound, wirelessly communicate the rate of fluid removal to a remote device, and output an indication when the rate of fluid removal meets a threshold.

A smoke evacuator for use with a surgical access device includes an evacuation ring having an inner peripheral surface defining one or more channels therein disposed in fluid communication with an operating cavity. A connection port is disposed thereon in fluid communication with the channel(s) and adapted to connect to a smoke evacuation system. The evacuation ring includes a profile having an inner flange that forms part of the inner peripheral surface of the evacuation ring and one or more lower flanges, the inner flange is configured to mechanically engage a rim of an access device and the lower flange(s) is adapted to mechanically engage a wound guard, wherein engagement of the inner flange of the evacuation ring atop the access device and engagement of the lower flange(s) with the wound guard secures the access device, the wound guard and the smoke evacuation ring within the operating cavity.

The present invention relates to a system and method for pulse cycle pressure modulation and negative pressure therapy in a cardio synchronous manner to improve distal limb blood flow applying negative or variable pressure to a portion of the body. The invention relates to methods and apparatus for the application of a sequential and gradient pulse wave for treating wounds that are difficult to heal or livelihood limiting claudication and/or ischemic rest pain. An integral part of the present invention includes methods to determine blood flow and effects of treatments on tissue.

A method of managing a medical suction device through a network may be embodied by the management server through the steps of: storing operation information of at least one medical suction device in a storage unit provided in the management server, generating an operation start determination reference value of the medical suction device based on the operation information, receiving information on conditions of a patient from a medical suction device installed at an outside, and determining whether to start an operation of the medical suction device that has transmitted the information on conditions of the patient based on the operation start determination reference value and the information on conditions of the patient.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

A fat suction and graft syringe includes a negative pressure adjustment mechanism. The negative pressure state in a barrel can be maintained during a procedure only by pulling and releasing a plunger, and only by slightly rotating the plunger. The plunger can be pushed inside the barrel without being constrained by a multi-level holding plate and a single-surface rotation clip, whereby the syringe has enhanced convenience in the use and production thereof so that many practitioners accustomed to using a normal syringe can easily use the syringe without separately learning how to manipulate the syringe.
