This invention relates to the field of gastric residual volume detection technology, specifically a Bluetooth transmission device for ultrasound monitoring of gastric residual volume during enteral nutrition for infants and young children. The device includes a main body structure and a transmission device-mounted control system. The control system includes an ultrasound signal acquisition module, a signal processing module, a Bluetooth transmission module, a residual volume calculation module, and a graded alarm module. This invention achieves this by selecting a target frequency band to match the acoustic impedance characteristics of gastric fluid, dynamically tuning the probe's transmission power based on abdominal wall thickness to reduce gas and tissue interference and improve signal accuracy. It corrects signal mapping deviations based on a three-dimensional gastric cavity model, compensates for postural shifts, generates a gastric fluid distribution model to enhance accuracy, dynamically segments data packets and embeds time-series tags to ensure complete transmission and anti-interference capabilities, combines intake rate and gastric emptying curve correction parameters to quantify volume and compensate for errors, improving calculation reliability, and generating graded alarm commands to link with clinical operations.

Intragastric device intended to be inserted into a gastric cavity to restrict its capacity. To contribute to optimal adaptation, its design is based on the principle of neutral buoyancy. The device comprises an inner core and an outer covering (2). The inner core consists of a closed chamber (1) and a first valve (4) connecting the inside of the chamber (1) to the outside, through which a pressurised fluid is introduced into the chamber (1). The outer covering (2) comprises a first cavity (5), in which the core is housed, and a second valve (7), through which a volume of fluid is introduced into the free space of the cavity not occupied by the chamber (1). This fluid in the first cavity (5) is at a different pressure to that of the fluid introduced into the chamber (1).

This invention discloses a pediatric double-balloon catheter for esophageal and gastric pressure monitoring, comprising an outer sheath and an inner core tube. Both ends of the outer sheath are open. The inner core tube is slidably inserted into and passes through the outer sheath. One end of the outer sheath is provided with a dynamic locking component for fixing the inner core tube, and the inner circumferential wall of the other end of the outer sheath is in a sealed sliding fit with the outer circumferential wall of the inner core tube. An esophageal pressure inflation / measurement connector is located on the exterior of the outer sheath near the dynamic locking component, and an esophageal pressure balloon is circumferentially sealed on the exterior of the outer sheath away from the dynamic locking component. This invention solves the clinical problem of traditional fixed-spacing catheters, which cannot simultaneously ensure accurate placement of the esophageal balloon in the lower esophagus and complete placement of the gastric balloon within the gastric cavity, making the same catheter applicable to a wide age range from newborns to adolescents.

The invention discloses a gastric emptying parameter detection system for gastric ultrasonic examination, and belongs to the field of medical images. The gastric emptying parameter detection system for the gastric ultrasonic examination comprises an ultrasonic image acquisition module, an image processing module and a gastric emptying parameter calculation module. The problem that an existing gastric emptying function detection method has limitation is solved, standard section image acquisition can be accurately carried out on the antral sinus part before and after each drinking node through the image acquisition module, and the image processing module extracts and draws gastral cavity boundaries in a time sequence ultrasonic image through an image segmentation algorithm; the gastric emptying parameter calculation module calculates gastric emptying parameters including initial emptying time, emptying curve slope, semi-emptying time, emptying rate at a specific time point and the like based on gastral cavity area data of a time sequence, and the gastric emptying parameter calculation module calculates the gastric emptying parameters including the initial emptying time, the emptying curve slope, the semi-emptying time, the emptying rate at the specific time point and the like based on the gastric cavity area data of the time sequence, so that the accuracy and reliability of gastric emptying area measurement are improved. And objective evaluation of the gastric emptying function can be realized.

Embodiments of the present application provide a gastric mucosa image positioning method, device, computer equipment and storage medium. The gastric mucosa image positioning method comprises: acquiring a gastroscope image to be positioned for gastric mucosa foreign matter; identifying a gastric cavity anatomical part and gastric mucosa foreign matter in the gastroscope image; calculating a distance value of the gastric cavity anatomical part and the gastric mucosa foreign matter; determining a reference gastric cavity anatomical part according to the distance value, the reference gastric cavity anatomical part being a reference for positioning the gastric mucosa foreign matter; and determining a relative position of the gastric mucosa foreign matter and the reference gastric cavity anatomical part. Embodiments of the present application can obtain the relative position and distance of the gastric mucosa foreign matter and the gastric cavity anatomical part, and provide an important basis for accurately judging the position of the gastric mucosa foreign matter.

The application discloses an application of an endoscopic continuous suturing device in preparation of a gastric plication suturing medical instrument, and the endoscopic continuous suturing device comprises a suture wire with uniformly distributed barbs, a plurality of titanium clips and a pushing device, the suture wire is 6-10 cm long, and the two ends of the suture wire are respectively provided with a front end connecting ring and a rear end connecting ring; a sheath pipe is arranged at the position close to the rear end connecting ring of the suture wire; the titanium clip is used for clamping and fixing the gastric mucosa tissue and the suture wire; the pushing device is used for tightening the suture wire and comprises a traction steel wire, an inner push tube and an outer sheath tube which are sleeved from inside to outside and slide; a metal hook is arranged at the front end of the traction steel wire; two operation handles are arranged at the rear end of the pushing device and are used for respectively controlling the inner push tube and the traction steel wire to move forward and backward.
