A flexible medical intubation instrument provided for placement into an animal or human patient comprises a catheter with at least a pair of longitudinally extending lumens or channels including a sensor and/or actuator channel and a working channel. In the sensor/actuator channel is provided a fixed or slideably removable sensor cable having a sensor for sensing a characteristic or condition including any of the following: a visual sensor for optical viewing, a chemical sensor, a pH sensor, a pressure sensor, an infection sensor, an audio sensor, or a temperature sensor. The sensors are coupled by the sensor/actuator cable through light transmission, electric current, or radio transmission to a viewing instrument or other output device such as a meter or video screen for displaying the condition that is sensed within the body of the patient while the flexibility of the composite structure comprising the catheter and cable enable the entire instrument to flex laterally as it moves through curved passages or around obstructions during insertion or removal. While making observations through the sensor channel, the working channel simultaneously functions as a drain or an irrigation duct, a feeding tube, or to provide a passage for the insertion of one or a succession of surgical devices such that the catheter serves as a protective artificial tract or liner as surgical devices are inserted and removed through it in succession so as to minimize tissue trauma, infection, and pain experienced by the patient. The instrument can be used in urology, as well as a visually directed nasogastric tube, as a visually directed external gastrostomy tube, or as a visually directed internal gastric tube or percutaneous endoscopic gastrostomy tube and in other applications.

A gastrostomy device having an external inflationary indicator is disclosed which comprises an external retention member having a tubular member extending therefrom for providing a fluid pathway to a patient's gastrointestinal tract. The external retention member includes a fluid conduit in communication with a inflationary lumen for providing fluid to inflate a balloon member attached to the tubular member. The inflationary indicator includes a thin wall section of the external retention member which forms a flexible membrane that defines first and second portions divided by a separating bar. The flexible membrane assumes a convex shape when the balloon member is in an inflated condition, while it assumes a concave shape when in the deflated condition. The shape in shape of the flexible membrane provides the user with a visual and tactile indication as to the inflationary state of the balloon member.

A gastrostomy tube including a body having a hub portion and a tubular portion. The body defines a primary lumen having a first end in communication with an opening in the hub portion.

The port is adapted to engage an end of a luer tip syringe. The tube includes an external balloon located at a proximal end of the body. The tube has an internal balloon located distally from the external balloon. The internal and external balloons are in fluid communication with the port via the secondary lumen such that each is inflatable. The internal and external balloons enable a clinician to indirectly observe the internal balloon by observing the external balloon.

The engaging member 22 is also provided with a lower engaging portion 25 which can engage with an outer fixing member 10a and an upper engaging portion 26 which can engage one of the engaging step portions 24a of the rod 21.

A nutritional composition for gastrostomy-tube patients who are at an increased development risk of aspiration pneumonia and require careful risk management, which can be more safely consumed by gastrostomy-tube patients while suppressing the development of aspiration pneumonia, is administered to those patients who require risk management for aspiration pneumonia, and contains a protein source, a carbohydrate source, and a lipid source, the protein source including only amino acids.

A medical instrument provides assistance in reinserting a gastrostoma tube easily. The instrument includes a searching bar and a fistula expander. A main body of the searching bar is a tubular body, a front end of the searching bar presents a hemispherical shape, and a side hole is defined near the front end. The fistula expander includes a funnel-shaped portion divided into two portions at a front end portion of the fistula expander, two grip bars secured to both sides of the funnel-shaped portion respectively, and a spring portion secured to rear ends of the grip bars. One may visually identify, and take photographs of, the location of the front end portion and/or side portion of the searching bar while light from an light source through optical fibers is radiated outwardly via a lens aperture or apertures in the front end and/or front end portion.
