  • Publication number: 20230014924
    Abstract: A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise at least two pressure relief valves that open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

  • Publication number: 20220257311
    Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

  • Patent number: 11400258
    Abstract: A sutureless chest tube adhesion assembly configured to quickly and easily anchor a chest tube is described. The assembly generally comprises a notched flexible substrate adapted to adhere to human skin 415. A chest tube incision in a notched region of the substrate provides an entry point for the chest tube which is anchored to the substrate by way of an intermediate flexible membrane that covers and adheres to the chest tube and substrate. The intermediate flexible membrane has a matching notched region adapted to accommodate the chest tube. The chest tube and incision are adapted to be covered by a transparent cover sheet which covers and adheres to a portion of the substrate, the intermediate flexible membrane and to a portion of the human skin 415.

  • Publication number: 20220047896
    Abstract: The disclosed passive facemask embodiments having a single exchange port covered by a filter are from a family of transparent facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used, facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding the wearer's mouth and face with opaque filter material. Accordingly, some embodiments described herein present a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth by providing a filtration system along or near the periphery of the facemask.

  • Publication number: 20210345940
    Abstract: Disclosed are embodiments describing finger calipers with a pair of lever arms pivotally attached to a hand plate via a pivot point at their respective proximal ends. Each of the lever arms extend along the length of a finger and attach to the end of the respective finger via a finger cuff or some other attachment means. Accordingly, the lever arms can open and close, or otherwise splay apart, in a scissor like manner when the fingers that they are attached to open and close or otherwise splay apart. A ratchet system comprised by one of the lever arms and the hand plate allow for one-way motion of the ratcheted lever arm. The other lever arm freely pivots across the hand plate. When a medical examiner is using the finger calipers, they can reliably measure a dilated cervix by reading a corresponding dilation measurement indicium associated with the ratcheted lever arm.

  • Patent number: 11007000
    Abstract: A surgical instrument includes a reusable component and a disposable component selectively separable from and engagable with the reusable component. The disposable component includes an end effector and a mechanical actuator operable to induce mechanical movement of the end effector. The reusable component is configured for providing electrosurgical energy to the disposable component when engaged with the disposable component. A physical mating feature is configured to maintain engagement between the reusable and disposable components when the reusable and disposable components are engaged, and an electrical mating feature is configured to transmit electrical energy between the disposable and reusable components when the disposable and reusable components are engaged. All mechanical motion resulting from operation of the mechanical actuator may be contained within the disposable component.

  • Patent number: 10959770
    Abstract: A method of assembling an electrosurgical instrument includes coupling first and second shafts to each other about a pivot. Each of the shafts has an interior side facing the other shaft and an exterior side opposite the interior side. The method also includes disposing a knife blade at least partially through a passageway defined through the pivot from the exterior side of the first shaft and coupling a knife actuation mechanism to the first shaft from the exterior side of the first shaft. The knife actuation mechanism is configured to move the knife blade through the passageway.

  • Publication number: 20210069409
    Abstract: An implantable externally driven fluid delivery system for localized delivery of medical agents and drugs, such as antibiotics, may be provided herein. The fluid delivery system includes a housing that incorporates a filling septum connected to a flexible internal reservoir. The reservoir is connected to a miniature diaphragm pump with coupled magnetic components. The entire fluid delivery system is implantable into a body cavity or surgically formed location that provides for local medical agent delivery. The reservoir is filled via percutaneous injection through the skin into the septum. Fluid delivery is achieved through proximity of the external controller that generates an oscillating or reversing magnetic field suitable to actuate the pump's diaphragm resulting in controlled fluid flow. Once local drug delivery treatment is complete, the controller can be discarded.

  • Publication number: 20210038841
    Abstract: An endotracheal tube apparatus with improved deployment and long-term comfort to a patient generally includes a cap mechanism that can direct enriched oxygen towards the patient's lungs while the endotracheal tube apparatus is being inserted in a patient's trachea. Once the endotracheal tube is fully inserted in the trachea, the cap mechanism can be made to redirect the enriched oxygen to inflate an inflatable cuff integrated with the endotracheal tube thereby blocking off the vocal cord region in the patient and stabilizing the endotracheal tube in the trachea. When the cuff is inflated, the cap mechanism can be made to ventilate the patient.
