  • Patent number: 11808568
    Abstract: The invention relates to a method of inner light layer illumination for optical imaging and detection in turbid media and apparatuses designed based on this method. This invention uses multiple beam interference to create destructive interference in the propagation path to reduce the illumination beam intensity and so to reduce absorption and scattering of the turbid media, and to create constructive interference to produce composite light intensity maximum which forms an inner light layer to illuminate the object. The theoretical analyses and mathematical calculations have proved the feasibility of the method. The designed apparatuses have great performances. Compared with the traditional technology, this method can enhance the signal strength more than 600 dB. The imaging depth can be over 5 cm in human body, and more than 500 m in clear seawater. The imaging resolutions are <1 ?m along object plane and approximate 1 ?m along direction of depth of field.

  • Patent number: 11471573
    Abstract: A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.

  • Patent number: 10646667
    Abstract: According to one embodiment, a method includes positioning a trocar having a primary pressure sensor in or on the trocar into a patient cavity. The method also includes supplying an insufflation fluid to the patient cavity and measuring a pressure in the patient cavity by the primary pressure sensor. The method further includes controlling the supply of insufflation fluid by an insufflator to the patient cavity based at least on the measured pressure and determining by a processor associated with the insufflator that the measured pressure may be inaccurate and in response, controlling, by the insufflator, the supply of insufflation fluid to the patient cavity based at least on a pressure measured by a backup pressure sensor rather than based on the measured pressure.

  • Patent number: 10328184
    Abstract: The current invention discloses a wound treatment device having a wound covering member, an applicator unit, and two lumens. The wound covering member may cover a wound. Sealing mechanism of the wound covering member may be used to form a sealed wound enclosure over and around the wound. The two lumens, including a negative pressure lumen and an oxygen lumen, connect the wound enclosure to the applicator unit. The applicator may be used to apply alternating and cycling negative pressure and oxygen to the wound enclosure, facilitating the wound healing process. The levels and durations of negative pressure, as well as the purity, amount, and durations of oxygen, may be adjusted by the applicator unit.

  • Patent number: 10258463
    Abstract: A novel phakic intraocular lens implantation without viscoelastics and an instrument thereof. The special designed instrument is employed to achieve a purpose of maintaining an anterior chamber only with a perfusion liquid in the surgery, so as to get rid of the influence of the viscoelastics completely. The viscoelastics are not used, so that there is no need to inject the viscoelastics or remove the viscoelastics as in traditional methods, the surgery time is shortened such that total time of surgical procedures from incision construction to incision hydration can be reduced to only 1˜3 minutes, and viscoelastic-related complications, such as postoperative high intraocular pressure and lens opacity, are completely avoided.
