Clamping mechanism for dialysis tubing

Номер: GB2448374A
Принадлежит:

A clamping mechanism for dialysis tubing comprises a clamp and a pin 4. The pin 4 has a hole 5 for the tubing to pass through. It has an enlarged central portion 2 and a narrow portion 3. The clamp also has hole 10 for the tubing to pass through. The point 1 of the pin 4 passes through recesses 11 and 12 in the clamp. When the enlarged portion 2 is positioned in recess 12, the tubing is unclamped. Should a needle attached to the tubing disconnect from a patient, the pin 4 will slide into the clamp, once the pin travels more than a certain distance, the narrow portion 3 of the pin 4 will engage recess 12, causing jaws 6 to clamp the tubing, thus stopping the blood flow, in this case the venous blood flow. The jaws 6 can be opened and the pin 4 reset by pressing arms 9. The clamp has means 8 to attach the clamp to a patient.

Method for treating dialysate, dialysis system, and method for pre-evaluating dialysis patients for treatment with same

Номер: AU2015266980A1
Принадлежит: Watermark Intellectual Property Pty Ltd

A method for treating dialysate solutions used in dialysis wherein dialysate is treated in an early part of a dialysis treatment session by external infusion of bicarbonate solution into the dialysate circuit to eliminate the need for bicarbonate requirements in concentrates used for preparation of precursor dialysate (priming) solutions and/or for a solid bicarbonate layer in a sorbent cartridge. Dialysate is treated in a latter part of a dialysis treatment session by introduction of sterile dilution water to reduce sodium concentration in the dialysate. The method provides a more efficient and reduced use of dialysate fluids, electrolytes, sorbent cartridge materials, equipment scale, or any combinations of these, while maintaining purity standards and applicable physiological ranges for bicarbonate, sodium, and other dialysate solution components over the course of a dialysis treatment session.

Method and apparatus for machine error detection by combining multiple sensor inputs

Номер: US20120194335A1
Принадлежит: Nxstage Medical Inc

One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be serious. There are a number of mechanisms for detecting and preventing leaks, but none is perfect. This tends to limit the use of such equipment in unsupervised settings, such as the home will be limited. Some leak detection schemes can be made sensitive enough to detect the barest of leaks, but when this is done, they result in too many false positives. The invention combines information from multiple inputs to enhance sensitivity in leak detection and reduce the problem of false positives.

The process may be combined with the administration of gal-3 binding agents, such as modified citrus pectin, to further lower unbound gal-3 levels, to the point where gal-3 in the tissues may be addressed. This method may also be combined with removal of TNF receptors to provide an effective treatment for cancer.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on the dimensions and the distensibility of the non-occluded portion of the patient line.

LASER-BASED TREATMENT FOR MALARIA

Malaria, caused by the parasite , is a devastating disease killing more than people a year worldwide. replicates within erythrocytes by digesting hemoglobin, producing haemozoin as a byproduct which accumulates within the parasite. The development of vaccines is hampered by lack of memory immune response, while the long-term effectiveness of current anti-malaria drugs is limited due to the emergence of drug-resistant strains. Furthermore, people who are deficient of the enzyme glucose 6-phosphate dehydrogenase exhibit fatally-adverse drug effects. To overcome these hurdles, I propose a novel laserbased, non-pharmacological treatment for malaria. The treatment is based on the ability of haemozoin to convert light in the near infra-red into ultra-violet (UV) radiation via Third Harmonic Generation. The UV light produced by haemozoin can in turn kill the parasite. In experiments with infected erythrocytes we obtained a 4-log reduction in parasetemia following six passes of the blood through the laser beam. 1. An apparatus comprising a pulsed near infra-red (NIR) laser and a dialysis machine equipped with a NIR transparent window for the treatment of malaria by irradiation of the infected perfused blood through the window.2.
