A sheath for a medical instrument includes an elongate body extending from a proximal end to a distal face. The elongate body may be configured to axially extend from a first length to a second length greater than the first length. The sheath may include a first hollow lumen extending from a first end proximate the proximal end to a second end proximate the distal face, and a second hollow lumen extending from the proximal end to the distal face. The second lumen may be open at the distal face. The sheath may also include a transparent window positioned at the second end of the first lumen to seal the first lumen at the second end. The transparent window may be configured to transmit light therethrough.

An otoscope, comprising: (a) a flexible speculum, operable to be inserted into an ear canal; (b) a stopper, coupled to the flexible speculum, operable to limit penetration depth of the flexible speculum into the ear canal; and (c) an imaging sensor, located inside the flexible speculum, operable to capture an image of an eardrum of the ear canal; wherein a flexibility of the flexible speculum allows alignment of the imaging sensor according to a shape of the ear canal.

The present invention relates to a cover having a plurality of moveable, external, angled projecting elements for use with flexible medical scoping devices such as endoscopes or enteroscopes. The invention includes the cover with an over cuff and use of the disposable removable covering in methods of medical scoping procedures or examinations. The invention also includes an applicator for assisting in placing the covering about or over a medical device and a kit of parts.

A laparoscopic medical device includes an oximeter sensor at its tip, which allows the making of oxygen saturation measurements laparoscopically. The device can be a unitary design, wherein a laparoscopic element includes electronics for the oximeter sensor at a distal end (e.g., opposite the tip). The device can be a multiple piece design (e.g., two-piece design), where some electronics is in a separate housing from the laparoscopic element, and the pieces (or portions) are removably connected together. The laparoscopic element can be removed and disposed of; so, the electronics can be reused multiple times with replacement laparoscopic elements. The electronics can include a processing unit for control, computation, or display, or any combination of these. However, in an implementation, the electronics can connect wirelessly to other electronics (e.g., another processing unit) for further control, computation, or display, or any combination of these.

A suction ring for mounting close to the mouth opening of a dental patient, comprising an extraoral tensioning element. The tensioning element is realised as a suction tensioning element and forms or spans a negative pressure space with a film element. The negative pressure space extends annularly or partially annularly, and the negative pressure space has at least one suction nozzle, in particular pointing radially inwards.

A laryngoscope blade which improves the transmission of light from the laryngoscope to enhance the amount of light reflected from an area of interest in a patient. The laryngoscope blade has a channel which extends at least partially though the blade and receives a light source. The channel has a substantially transparent end face which is situated towards the blade end and has an optical clement adapted to reduce the ambient light signal from the light source in the channel.

An adjustable endoscope fixing device, comprises a tail bed, a three-way connector and a locking screw; an outer wall surface of a straight column section of the tail bed is provided with a rectangular slot; and an outer wall surface of a first connecting end of the three-way connector is provided with a locking structure, and the straight column section of the tail bed is connected to the first connecting end of the three-way connector, and the tail bed is fixed to the three-way connector by the locking structure.

A steering assembly of a medical device may comprise a handle having a recess and first and second wire guides disposed within the recess. At least one of the first or second wire guides may be keyed to the recess to prevent rotation of the first or second wire guide within the recess. First and second wire segments may be configured to steer a sheath coupled to the steering assembly in first and second directions. The first wire segment may pass through a first gap between the first wire guide and the second wire guide. The second wire segment may pass through a second gap between the first wire guide and the second wire guide. Neither of the first nor the second gap may occupy any overlapping space.

An applicator for positioning a sleeve accessory on a medical speculum, and a method for using the applicator, is provided. The applicator has a flat, oblong shape with a distal end and a proximal end, the proximal end being broader than the distal end. The distal end of the applicator includes a first prong and a second prong. At least a portion of the distal end of the applicator is configured to slide into a lumen of a sleeve accessory to facilitate positioning of the sleeve accessory on a medical speculum.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.
