Apparatus, system and method for providing pressurized infusion of liquids and, more particularly, providing a stable and pressurized flow of fluid to the eye during surgery. Aspiration fluid may be received via an aspiration line at a first peristaltic pump, where aspiration fluid is transferred to a Venturi tank reservoir coupled to a second peristaltic pump. Fluid from a fluid source is provided via a third peristaltic pump to a pressurized infusion tank. A determination is made if the pressure in the pressurized infusion tank is at a predetermined level, where fluid may be transferred from the pressurized infusion tank to an irrigation line when pressure in the pressurized infusion tank is determined to be at the predetermined level. Alternate activation of a plurality of aspiration and irrigation lines are also provided.

Provided herein are compositions, including products of manufacture such as formulations, and kits, and methods, for treatment, amelioration or prevention of a disease, infection or condition caused or exacerbated by a pathological or abnormal in situ microbiome space, or a gastrointestinal (GI), disease, infection or condition or a disease or condition caused by, initiated by or exacerbated by a pathological microbiome, e.g., by a pathological GI or colonic microbiome residing in a gut mucosa.

A wound therapy system includes a negative pressure circuit configured to apply negative pressure to a wound, a pump fluidly coupled to the negative pressure circuit and operable to control the negative pressure within the negative pressure circuit, a pressure sensor configured to measure the negative pressure within the negative pressure circuit or at the wound and a controller communicably coupled to the pump and the pressure sensor. The controller is configured to execute a pressure testing procedure including applying a pressure stimulus to the negative pressure circuit, observe a dynamic pressure response of the negative pressure circuit to the pressure stimulus using pressure measurements recorded by the pressure sensor, and estimate a wound volume of the wound based on the dynamic pressure response.

A system for detecting intraocular pressure events during phacoemulsification surgery having a surgical console, a handpiece having a proximal end being communicatively connected to an irrigation line and an aspiration line; a first sensor in communication with the aspiration line or the irrigation line for providing a first measurement value; and a second sensor in communication with the aspiration line for providing a second measurement value; and wherein at least one characteristic of the irrigation fluid or aspiration fluid in their respective lines is changed in accordance with the difference between the first measurement value and the second measurement value. A system for calibrating patient eye level and wound leakage; detecting occlusion or post occlusion surge; determining BSS usage or remaining in a container; and detecting a fluid line abnormality using a first sensor and a second sensor in different configurations and differences in first and second measurement values.

Methods and systems are provided for diagnosis and possibly treatment of the large intestine, using samples from at least three portions of the large intestine, including sampling the ascending proximal portion thereof. Samples from the ascending portions of the large intestine were found to differ in their microbial characteristics significantly from prior art stool samples and from samples taken from the descending and transverse parts of the large intestine—enabling more accurate diagnosis and possibly more effective treatment of diseases of the large intestine.

In one embodiment, a phacoemulsification system includes a phacoemulsification probe including a distal end including a needle, an irrigation channel to convey irrigation fluid to the distal end, an aspiration channel to convey eye fluid and waste matter away from the distal end, wherein the aspiration channel includes a first and second section, a valve including an inlet and outlet port, the first section of the aspiration channel being coupled with the inlet port and the distal end, the second section of the aspiration channel being coupled with the outlet port, the valve being configured to selectively control fluid connectivity in the aspiration channel between the inlet port and the outlet port, and a bypass channel coupled with the irrigation channel and the second section of the aspiration channel to allow a portion of the irrigation fluid in the irrigation channel to enter the second section of the aspiration channel.

The disclosed apparatus, system and method may include at least a surgical fluid container that includes a fluid reservoir capable of containing the surgical fluid and a gas pressure pocket applied to the surgical fluid therewithin; a first external port extending from outside the fluid reservoir into fluid communication with the surgical fluid within the fluid reservoir; and a second external port extending directly from outside the fluid reservoir into the gas pressure pocket.

An irrigation function-equipped suction device including a suction device body, a suction path, an irrigation path and a flexible tube. With communication or closing of the suction path and the flexible tube by a first switch mechanism, the irrigation path and the flexible tube are caused to be closed off from each other or to communicate with each other by a second switch mechanism. The first switch mechanism is provided in a first section inside the suction device body, and the second switch mechanism is provided inside the irrigation path between the conversion mechanism and the flexible tube. The closing valve included in the second switch mechanism is disposed at a position on a side opposite to the flexible tube relative to the first switch mechanism and the conversion mechanism.

A medical device is provided for irrigation of a patient wound site. The device contains a tube having a proximal portion adapted to receive an irrigation solution, a distal portion having a nozzle and an intermediate portion for transporting the solution. The tube has a barrel portion that may be manipulated by a user to position the device relative to the wound site. A distinctive nozzle has a body formed with a distally leading channel presenting a semispherical first spatial conformation and a proximally leading opening formed in the body presenting a second spatial conformation intersecting the semispherical terminus. This geometry, derived from principles of flow mechanics discussed herein, defines what will be described as an “effective diameter” of the nozzle. An assembly and system utilizing the device are also disclosed. The invention utilizes a fluid-isolating durable peristaltic pump for a continuous flow of irrigation solution, along with a single use tube set that embodies the device.

A device including a water reservoir, in which water reservoir is configured to be operable for storing water. A head portion, in which the head portion contains an ear irrigation tip, a top tubing that is configured to be operable for directing water from the water reservoir to the ear irrigation tip, a wash basin, wherein the wash basin is operable for catching water coming out of the ear irrigation tip, and a splash disk, wherein the splash disk is configured to be operable for redirecting the water and/or debris into the water basin. A main body, in which the main body contains a control interface, wherein the control interface is configured to change a flow rate of the water being pumped out of the ear irrigation tip.
