Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a nutrition tube. Background Art

[0002] Patients with various malignant tumors such as esophageal cancer, oral cancer, head and neck tumors, gastric cancer, pancreatic cancer, liver cancer, lung cancer, intensive care patients, and infants often need nutritional tubes for feeding and medication.

[0003] When placing a feeding tube, the insertion end of the feeding tube needs to be placed at the patient's jejunostomy or gastrostomy. The feeding tube is often placed with the assistance of a gastroscope, and the insertion end of the feeding tube is inserted into the gastroscope. When the insertion end of the feeding tube is placed in place, the feeding tube is easily brought out when the gastroscope is removed, which requires high technical skills of medical personnel. Utility Model Content

[0004] The technical problem to be solved by the utility model is to study a nutrition tube which is not easy to be taken out when the gastroscope is withdrawn.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A nutrition tube comprises a nutrition tube body, an elastic membrane, a limiting ring and a sleeve ring. A liquid outlet is provided at the insertion end of the nutrition tube body, and the elastic membrane and the limiting ring are sequentially arranged on the nutrition tube body at the inner end of the liquid outlet hole. The elastic membrane is an umbrella-shaped film, and a plurality of compression springs are built in along the extension direction; the opening of the elastic membrane is arranged toward the insertion end of the nutrition tube body; the sleeve ring is arranged outside the elastic membrane; and the nutrition tube body outside the elastic membrane is placed in a gastroscope.

[0007] The beneficial effect of the utility model is that when the gastroscope carries the insertion end of the nutrition tube body to the designated position, the biopsy forceps in the gastroscope clamp the ring to pre-expand the elastic membrane, and the outer wall of the elastic membrane presses against the inner wall of the port of the gastroscope. When the gastroscope is withdrawn backward, the port of the gastroscope releases the restriction on the elastic membrane, and the elastic membrane expands instantly. When the elastic membrane expands, it drives the nutrition tube body to slide out of the gastroscope, so that the insertion end of the nutrition tube body extends a long distance relative to the port of the gastroscope, and is not easily dragged out during the backward withdrawal of the gastroscope.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, there are multiple liquid outlet holes, which are symmetrically distributed.

[0010] Furthermore, a gravity block is arranged at the insertion end of the nutrition tube.

[0011] Furthermore, lubricating oil is applied outside the elastic membrane.

[0012] Furthermore, when the elastic membrane is expanded, the angle between the elastic membrane and the outer wall of the nutrition tube body is less than or equal to 15°. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figures 1 to 6 As shown, embodiment 1 of the utility model is a feeding tube, comprising a feeding tube body 2, an elastic membrane 3, a limiting ring 4 and a sleeve ring 5. A liquid outlet 6 is provided at the insertion end of the feeding tube body 2, and the elastic membrane 3 and the limiting ring 4 are sequentially arranged on the feeding tube body 2 at the inner end of the liquid outlet 6. The elastic membrane 3 is an umbrella-shaped film, and a plurality of compression springs 31 are built in along the extension direction; the opening of the elastic membrane 3 is arranged toward the insertion end of the feeding tube body 2; a sleeve ring 5 is arranged on the outer sleeve of the elastic membrane 3; the feeding tube body 2 outside the elastic membrane 3 is built in the gastroscope 1.

[0023] When the gastroscope 1 carrying the insertion end of the nutrition tube body 2 reaches the specified position, the biopsy forceps in the gastroscope 1 clamp the ring 5 to pre-expand the elastic membrane 3, and the outer wall of the elastic membrane 3 presses against the inner wall of the port of the gastroscope 1. When the gastroscope 1 is withdrawn backward, the port of the gastroscope 1 releases the restriction on the elastic membrane 3, and the elastic membrane 3 expands instantly. When the elastic membrane 3 expands, it will drive the nutrition tube body 2 to slide out of the gastroscope 1, so that the insertion end of the nutrition tube body 2 extends a long distance relative to the port of the gastroscope 1, and is not easily dragged out during the backward withdrawal of the gastroscope 1.

[0024] Embodiment 2 of the present invention is a nutrition tube, based on embodiment 1, with multiple liquid outlet holes 6, which are symmetrically distributed. The porous structure has uniform liquid outlet and is not easy to be blocked.

[0025] Embodiment 3 of the present invention is a nutrition tube. Based on embodiment 1, a gravity block 7 is provided at the insertion end of the nutrition tube. The gravity block 7 can increase the weight of the nutrition tube body 2, so that it is not easy to be carried out by the gastroscope 1. At the same time, under the action of gravity, the insertion end of the nutrition tube body 2 is always facing downwards and is not easy to get tangled.

[0026] Embodiment 4 of the present invention is a nutrition tube, based on embodiment 1, wherein lubricating oil is applied to the outside of the elastic membrane 3 to reduce the friction between the elastic membrane 3 and the end of the gastroscope 1 when the elastic membrane 3 is expanded.

[0027] Embodiment 5 of the utility model is a nutrition tube, based on any one of embodiments 1 to 4, the angle between the elastic membrane 3 and the outer wall of the nutrition tube body 2 when expanded is less than or equal to 15 degrees, so as to avoid the elastic membrane 3 from scratching the gastrointestinal tissue due to its excessive expansion, causing secondary injury to the patient.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
