A microneedle having a body including a base, shaft and pointed tip, and at least one lumen disposed within the shaft. The lumen having an opening that is offset from the tip and open to the exterior of the microneedle.

The improvement device provides an oral suction system for use with endo-tracheal tubes. The device provides alternative anti-infective components and a removable and/or disposable external sleeve, both for mitigation or elimination of risks for viral and/or bacterial contamination of the patient and healthcare professional.

A method and means effectively evacuates smoke plumes, vapors, aerosol release, mists, tissue and small particles produced from an operative nasal cavity and any other gas- or air-borne materials provided in or produced in the surgical environment. To this end, an evacuator tube is placed in the contralateral (suction) nasal cavity surrounded by a sealing member which blocks the space between the evacuator tube and nares and/or nasal vestibule.

The invention provides intravascular devices for treating certain medical conditions such as edema without causing thrombosis. The intravascular devices of the disclosure include non-thrombogenic surfaces that improve blood compatibility by reducing device-related thrombus formation and inflammatory reactions. The non-thrombogenic surfaces may include surface topographies (e.g., surface roughness) and modified chemistries (e.g., coatings and/or treatments), which prevent thrombosis by reducing local shear forces and inhibiting adhesion of blood clotting factors.

A medical device for use with an associated tube inserted into an incision formed in skin or tissue of a patient includes a dressing including an opening sized to receive and allow movement of the associated tube. A valve is operatively connected with the opening of the dressing and includes a main body; and an opening formed in a portion of the main body. The opening is sized and dimensioned to accommodate the surgical tube.

Certain embodiments provide an apparatus comprising a hand-piece, an outer tube coupled to the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an adapter, a proximal end of the adapter coupled to a distal end of a valve, the valve slidably coupled to the hand-piece, and a core slidably coupled to the hand-piece and having a distal end coupled to a proximal end of the valve. To retract the soft tip, the valve is retracted, causing the adapter, the valve, and the core to slidably retract in a proximal direction in relation to the hand-piece, and to extend the soft tip, the valve is protracted, causing the adapter, the valve, and the core to slidably protract in a distal direction in relation to the hand-piece.

An alternative device to a mask that blocks a patient's aerosol and avoids contamination of the patient's surrounding environment is described. The device has a flexible arm that holds an aerosol disposal pipe with one side connected to a wall, a bed, or pole attached to a floor. The second side of the flexible arm is attached to a circular or elliptical pipe that covers the face of the patient. The elliptical or circular pipe comprises of two independent moving and rotating halves to create two aerosol sucking planes. The sucking function is provided by sucking fans attached to the two halves of the circular or elliptical pipes or by a remote pump. The sucked aerosol may be filtered and released to the environment or guided to a sink P-Trap or an inlet of sewer.

A multi-lumen catheter, for insertion into and draining a body cavity, that mitigates the risk of obstruction of the drainage ports and drainage lumen of the catheter, reduces the detrimental effects caused by the suction forces of the drainage ports on the body cavity being drained, and reduces the risk of infection of the body cavity being drained by decreasing the residual volume of fluid retained in the body cavity being drained. These advantages are achieved by the novel approach of disposing a perforated filter membrane or a membrane having a relatively large entry port(s) between membrane struts over a segmented retention element and also over the drainage port(s) of the drainage lumen of the catheter thereby creating internal interstitial drainage channels and internal interstitial drainage cavities.

A self-placeable external catheter is disclosed that includes a catheter body having at least a top side and a bottom, a wicking area disposed on the top side, a finger covering extending from the bottom side of the catheter body creating a cavity configured to receive a user finger, and an aperture formed in the bottom side of the catheter, wherein the wicking area receives urine such that the urine passes through the wicking area, through the catheter body and through the aperture. The catheter tubing may be inserted into the aperture such that the urine passes through the wicking area, through the catheter body and through the aperture into the catheter tubing. An opening of the cavity may face a proximal side of the catheter body and the wicking area may include gauze.

A time saving sit on cardio pulmonary resuscitation device and method wherein the said device for providing cpr is adopted with an arrangement to seat a person and enable the start of cpr within five minutes of a heart attack affecting a patient, comprising of a reciprocating resuscitation force applicator where a counter force to the reactive force arising on applying compression force for resuscitation, said counter force being provided by the weight of a person sitting on the seating means and a belt based drive conveyance means forming a loop from top of a enclosure box allowing cpr without latching. A very clearly understandable, unambiguous, two step method of sitting on the device placed around the patient body, no confusion, no decision steps, no mental thinking on what to do. The device takes care of most decisions automatically.
