Patent number: 10556055Abstract: An improved method for separating whole blood into components and collecting a desired blood component. The method allows a desired blood component to be subjected to centrifugal forces within a separator for prolonged periods of time, yielding a cleaner cut and higher yield of the desired blood component. Whole blood is drawn from a source and pumped into a separator, the undesired blood components are removed from the separator at rates so as to build up the desired blood component in the separator. The desired blood component is only removed after a predetermined amount of the desired blood component has built up in the separator. It is preferred that the desired blood component be buffy coat and that the method be used to perform photopheresis treatments. In another aspect, the invention is a method of performing a full photopheresis treatment to treat diseases in a reduced time, preferably less than about 70 minutes, and more preferably less than about 45 minutes.Type: GrantFiled: April 19, 2017Date of Patent: February 11, 2020Assignee: Mallinckrodt Hospital Products IP LimitedInventor: Dennis Briggs

Patent number: 10543334Abstract: A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.Type: GrantFiled: March 16, 2017Date of Patent: January 28, 2020Assignee: Mallinckrodt Hospital Products IP LimitedInventor: Scott I.

Patent number: 10537697Abstract: A method and system for generating and delivering nitric oxide directly to a patient. A reaction chamber is provided that is located at or in close proximity to the patient and reactants within the reaction chamber react together to produce a predetermined amount of nitric oxide. The reaction is controlled by metering at least one of the reactants into the reaction chamber to generate a predetermined quantity of nitric oxide as required by the patient. The reactants can include a nitrite salt, such as sodium nitrite, and a reductant such as ascorbic acid, maleic acid or a mixture thereof. By generating and delivering the nitric oxide directly to the patient in close proximity thereto, the formation of NO2 is minimized. One or both of the reactants may be in liquid form.Type: GrantFiled: January 27, 2016Date of Patent: January 21, 2020Assignee: MALLINCKRODT HOSPITAL PRODUCTS IP LIMITEDInventors: Frederick Montgomery, Duncan Bathe
