Abstract
A wound cover connecting device for the sealing connection of a drainage tube and a wound cover covering a wound has a base body for the sealing contact on an outside of the cover. According to the invention, the device comprises at least one penetration element for producing a through-passage in the cover. The device enables a simple, fast, and tight connection between the cover and the tube. In addition, it enables a treatment of the wound that is as uniform and has as large a surface as possible.
Core Innovation
The invention relates to a wound cover connecting device for sealingly connecting a drainage tube and a wound cover closing a wound, wherein the device sealingly engages an airtight wound cover while forming a connection interface to a suction or drainage tube. The device has a main body bearing sealingly on an outer face of the cover, with a sealing element extending around the main body to seal the main body against the wound cover while the main body rests with its lower end face on the wound cover.
On the wound side, the main body is closed by a contact wall, and at least one penetration element creates a through-opening in the wound cover. The penetration element has a shape that is at least one of sharp-pointed or cutting, and protrudes from the lower end face of the main body while being arranged in the contact wall, such that continuous channels are formed to a suction space.
In described embodiments, the device includes uniformly distributed multiple penetrations and a flexible or adaptive contact wall to provide a tight, simple or fast connection and uniform vacuum or treatment across a large wound area. A multipurpose embodiment further provides a second main body with separate needles for simultaneous or selective suction and medicament or liquid or gas delivery.
Claims Coverage
The document includes one independent claim. It defines a wound cover connecting device by combining sealing engagement of an airtight wound cover with a contact-wall-mounted sharp-pointed or cutting penetration that protrudes from a lower main-body end face to create through-openings and continuous channels for connection to a drainage or suction space, with additional dependent refinements adding penetration and contact-wall configurations as well as an optional multipurpose delivery concept.
Sealingly connecting a drainage tube and a wound cover
A wound cover connecting device for sealingly connecting a drainage tube and a wound cover closing a wound, wherein the device has a main body for bearing sealingly on an outer face of the wound cover.
Sealing element surrounding the main body
The connection device has a sealing element extending around the main body, the sealing element being able to seal the main body against the wound cover while the main body is resting with its lower end face on the wound cover.
Sharp-pointed or cutting penetration creating a through-opening
The device has at least one penetration element for creating a through-opening in the wound cover, wherein the at least one penetration element has a shape that is at least one of sharp-pointed or cutting, and wherein the at least one penetration element protrudes from the lower end face of the main body.
Contact wall closed on the wound side with arranged penetration
The main body, on the wound side, is closed by a contact wall, and wherein the at least one penetration element is arranged in the contact wall.
Through-channel for aspirating liquid
The at least one penetration element includes a through-channel for aspirating liquid.
Self-adhesive sealing element
The sealing element is self-adhesive.
Attachment piece with comparative surface-area relation
The device includes an attachment piece connectable to a suction source, where the main body has a surface area greater than the cross-sectional area of the attachment piece.
Contact wall automatically adapting to the cover surface
The contact wall automatically adapts to the surface of the cover.
Multiple spaced-apart penetration elements
The at least one penetration element is multiple penetration elements spaced apart, configured to pierce the cover at multiple spaced-apart locations.
Across the claim set, the main inventive concept is a sealing main body that rests on an airtight wound cover and is closed on the wound side by a contact wall, where sharp-pointed or cutting penetration elements protrude from the lower end face and are arranged in the contact wall to create through-openings leading to the suction or drainage space. Dependent claims further specify multiple penetration elements, a through-channel for aspirating liquid, adaptive contact-wall behavior, and optional sealing and attachment relationships, with multipurpose concepts described in the provided content.
Stated Advantages
Tight connection.
Simple or fast connection.
Uniform vacuum or treatment across a large wound area.
Documented Applications
A wound suction or drainage connection for a wound cover closing a wound, using through-openings and channels to provide vacuum or treatment across a wound area.
A multipurpose wound connection supporting simultaneous or selective suction and medicament or liquid or gas delivery.
