Embodiment 1

[0025] Such as Figure 1-3 As shown, a self-regulating gastric tube for medical gastroenterology includes a gastric tube body 1, and a negative pressure tube 2 extending along the axial direction of the gastric tube body 1 is provided inside the gastric tube body 1, and the negative pressure tube 2 is made of an elastically deformable material. The end of the negative pressure pipe 2 is provided with a negative pressure mechanism 3, and the negative pressure mechanism 3 includes a liquid collection container 10 communicated with the negative pressure pipe 2. The liquid collection container 10 is connected with a negative pressure device 12 through an air guide pipe 11, and the negative pressure is activated. The device 12 can suck the gastric juice in the stomach of a gastroenterology patient into the liquid collection container 10 through the negative pressure tube 2, which is convenient and quick to use.

[0026] The gastric tube body 1 is fixedly sleeved with a ring-shaped ...

Embodiment 2

[0031] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that: the elastic airbag 18 is filled with a magnetorheological fluid 19, and the magnetorheological fluid 19 is micron-scale or nano-scale ferromagnetic particles immersed in a non-magnetic carrier liquid The formed suspension, the magnetorheological fluid 19, appears as Bingham fluid with high viscosity and low fluidity when a magnetic field is applied.

[0032] In this embodiment, the magnetorheological fluid 19 appears as a Bingham fluid with high viscosity and low fluidity under the magnetic field of the permanent magnet 16, which enhances the strength of the elastic airbag 18 and makes it difficult for the elastic airbag 18 to be easily damaged during the clamping process. Deformation occurs in patients with adverse reactions, further ensuring the stability of the clamping.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a medical self-adjusting gastric tube for the gastroenterology department. The gastric tube comprises a gastric tube body, a negative pressure tube extending in the axis direction of the gastric tube body is arranged in the gastric tube body, a negative pressure mechanism is arranged at the end part of the negative pressure tube, and an annular fixing seat fixedly sleeves the gastric tube body. A clamping and fixing mechanism is arranged on the annular fixing seat, a plurality of temperature difference pieces are longitudinally embedded in the gastric tube body at equal intervals, the high-temperature faces and the low-temperature faces of the temperature difference pieces are both coated with heat conduction coatings, an electric power storage piece is installed at the handheld end of the gastric tube body, and a plurality of liquid isolation films are arranged between the gastric tube body and the negative pressure tube in an annular array mode. The liquid isolation films are made of an electroactive polymer, the temperature difference pieces are electrically connected with the electric power storage piece, and the electric power storage piece is electrically connected with the liquid isolation films. Manual operation of medical staff is not needed, the tube diameters of the gastric tube body and the negative pressure tube can be automatically adjusted to the maximum state according to the use state, use is convenient, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a self-regulating gastric tube for medical gastroenterology. Background technique [0002] In the gastroenterology medical process, a gastric tube is needed to help patients who cannot swallow to deliver the necessary water and food. The traditional gastric tube is inserted directly from the patient's nasal cavity, through the pharynx, through the esophagus to the stomach. [0003] The traditional gastric tube is fixed with medical tape during use. However, due to the rejection of foreign bodies by the human pharynx and vent, retching is prone to occur, which leads to the problem of prolapse of the gastric tube, resulting in frequent and repeated reintubation. The patient brings great pain and discomfort; in addition, the main function of the gastric tube is to input nutrition through it, and also to perform negative pressure suction, and because the gastric tube is th...
