Description

Gastric tube auxiliary fixation device

Technical Field

The utility model belongs to the technical field of medical equipment and specifically discloses a gastric tube auxiliary fixing device.

Background Art

A nasogastric tube is a medical plastic hose that is inserted from the nostrils and reaches the stomach through the throat. In clinical practice, nasogastric tubes are often used for gastrointestinal decompression, cleaning, and enteral nutrition. In order to control the risk of infection and to improve comfort during use, unnecessary pulling or twisting of the nasogastric tube should be minimized during clinical care and daily activities of patients. Therefore, auxiliary fixation methods for nasogastric tubes are very important. At present, nasogastric tubes are generally fixed to the patient's nose with adhesive tape, but the problem of tape falling off due to sweating on the patient's face and oily nose wings often occurs.

Many special devices for fixing nasogastric tubes are disclosed in existing patents, such as an anti-falling device for fixing a gastric tube, publication number CN115778824B, a gastric tube fixing device, publication number CN115363962B, etc. However, the structures of such solutions are very complicated, and therefore there are the following problems: first, the cost is high in actual use; second, the operation is cumbersome during clinical use; third, the size is large, and fixing it on the patient's face will cause a lot of inconvenience and discomfort; fourth, it is a completely closed fixation, which is inconvenient to disassemble.

Therefore, based on the above problems, the inventors have designed a nasogastric tube auxiliary fixation device which has a simple structure and is easy to operate.

DETAILED DESCRIPTION

The following is further described in detail through specific implementation methods:

The reference numerals in the drawings of the specification include: a clamping block 1, an elastic rope 2, an earmuff 3, an opening 4, a semi-conical portion 5, a stopper 6, a semi-cylindrical portion 7, a pressing ring 8, a pressing rod 9, a first vertical plate 10, a second vertical plate 11, a first convex tooth 12, a second convex tooth 13, a clamping plate 14, a left elastic tooth 15, a right elastic tooth 16, an upper clamping group 17, and a lower clamping group 18.

As shown in FIG1 , an auxiliary fixation device for a gastric tube includes a block 1 for fixing the gastric tube. The block 1 in this embodiment is preferably made of rubber, and an elastic rope 2 connected to the block 1. The two sides of the elastic rope 2 are earmuffs 3. The earmuffs 3 are flat structures, and their material is elastic.

As shown in Figures 2 and 3, the card block 1 is a hollow structure, one side of the card block 1 is cut with an opening 4 in the vertical direction, the upper part of the card block 1 is a hollow semi-conical part 5, the lower part of the semi-conical part 5 is a raised stopper 6, the lower part of the stopper 6 is a hollow semi-cylindrical part 7, and a pressure ring 8 is hinged on one side of the semi-cylindrical part 7 located at the opening 4, and the side of the pressure ring 8 close to the semi-cylindrical part 7 is arc-shaped, and the arc-shaped side of the pressure ring 8 is processed with an anti-slip layer, and the movable end of the pressure ring 8 is hinged with a pressure rod 9, and there is also a member for fixing the pressure rod on the semi-cylindrical part 7. 9, the fixing part in this embodiment is preferably: including: a first vertical plate 10 and a second vertical plate 11 integrally formed on the semi-cylindrical portion 7, the lower part of the first vertical plate 10 away from the semi-cylindrical portion 7 and the upper part of the second vertical plate 11 away from the semi-cylindrical portion 7 are both integrally formed with a first convex tooth 12, and also include a second convex tooth 13 integrally formed on the upper and lower sides of the pressure rod 9, and the pressure rod 9 can be fixed between the first vertical plate 10 and the second vertical plate 11 through the cooperation of the first convex tooth 12 and the second convex tooth 13.
