A method of analysis using mass and/or ion mobility spectrometry or ion mobility spectrometry is disclosed comprising: using a first device to generate aerosol, smoke or vapour from one or more regions of a first target of biological material; and el mass and/or ion mobility analysing and/or ion mobility analysing said aerosol, smoke, or vapour, or ions derived therefrom so as to obtain first spectrometric data. The method may use an ambient ionisation method.

Systems and methods are disclosed for identifying images that contain polyps. An exemplary method for identifying images includes: accessing images of a gastrointestinal tract (GIT) captured by a capsule endoscopy device, where: each image of the images is suspected to include a polyp and is associated with a probability of containing the polyp, and the images include seed images, where each seed image is associated with one or more images of the images. The image(s) associated with each seed image is identified as suspected to include the same polyp as the associated seed image. The method includes applying a polyp detection system on the seed images to identify seed images which include polyps, where the polyp detection system is applied to each seed image of based on the image(s) associated with the seed image and the probabilities associated with the seed image and with the associated image(s).

Devices used during minimally invasive surgery (sometimes called minimal access surgery or laparoscopic surgery) for implantation and fixation of various cameras, for example, to the human body. An insertable device including a housing divided into two sections, a camera, a sensor, at least two LED lights, a lens flush located above the camera lens to clean a lens of the camera, and a motor for moving the camera in relation to the housing with pan and tilt capabilities. An insertion tool for inserting devices including a cannula, a top housing, and a bottom, wherein the bottom couples with the insertable device. A capture and fixation device for capturing and fixing an insertable device to an internal body cavity wall, the device includes a cannula, at least one slideable clamp device, and a retractable loop. Once the insertable device is positioned, the retractable loop fixes the insertable device to the body cavity wall.

An apparatus for performing ambient ionization mass and/or ion mobility spectrometry is disclosed. The apparatus comprises a substantially cylindrical, tubular, rod-shaped, coil-shaped, helical or spiral-shaped collision assembly; and a first device arranged and adapted to direct analyte, smoke, fumes, liquid, gas, surgical smoke, aerosol or vapor onto said collision assembly.

An apparatus is disclosed comprising a first device for generating aerosol, smoke or vapour from one or more regions of a target, an inlet conduit to an ion analyser or mass spectrometer, the inlet conduit having an inlet through which the aerosol, smoke or vapour passes, and a Venturi pump arrangement arranged and adapted to direct the aerosol, smoke or vapour towards the inlet.

The present invention provides a capsule for fluid sampling and drug delivery comprising: an enclosure, comprising a first enclosure, a second enclosure, at least a portion of the first enclosure comprising a support body having a plurality of first openings, a liquid-proof air-permeable membrane located at the first openings; a sampling/drug delivery assembly, comprising a storage chamber at least partially enclosed by the liquid-proof air-permeable membrane, a temporary storage chamber located in the enclosure, a first one-way element connecting the temporary storage chamber to outside of the capsule, a second one-way element connecting the temporary storage chamber to the storage chamber, and a pump changing pressure in the temporary storage chamber, wherein the first one-way element and the second one-way element have same direction of access; and a control module, comprising a microprocessor in communication with the pump. The capsule can realize multiple times of sampling and drug delivery.

The present invention provides a control method and system of a vibration capsule. The control method comprising: receiving a detection command of an acceleration sensor and controlling the acceleration sensor to work; obtaining a working acceleration data and transmitting the working acceleration data to an external device; and analyzing the working acceleration data and determining the position of the vibration capsule by the external device.

The present application provides a trypsin detection film, a preparation method therefor, application thereof and a trypsin detection kit, which relates to the technical field of trypsin detection. The preparation method for the trypsin detection film comprises the following steps: providing a polymer film substrate; immersing the polymer film substrate in a dye solution to attach a dye to the polymer film substrate, so as to obtain a trypsin detection film.

A capsule-type endoscope including a battery, a camera configured to capture internal organ images, a light source configured to irradiate light to capture the internal organ images, and a light source driving power line supplying power, stored in the battery, to the light source. The light source driving power line is a loop antenna coil for reception of a control signal from an external coupled loop antenna coil for transmission.

An endoscope system has an oxygen saturation calculation unit that calculates the oxygen saturation of an observation object, and includes an image acquisition unit that acquires a preliminarily captured image that is an image of the observation object, a correction unit that corrects an LUT that the oxygen saturation calculation unit uses for the calculation of the oxygen saturation, using the preliminarily captured image, a determination unit that determines a success or failure of the correction, and a warning unit that performs warning in a case where a determination result obtained by the determination unit is a failure.
