Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nasogastric feeding tube anti-dropout structure. Background Art

[0002] Nasogastric feeding is a procedure in which a gastric tube is artificially placed into the esophagus through the nasal cavity under special circumstances. The food is first ground into a paste using a grinder, and a large syringe is used to connect the large injection port under the gastric tube connector. After the connection is secure, a manual pressurized push rod piston is used to pump water and food into the patient's stomach to provide water and food to patients who cannot swallow independently and maintain metabolism, weight and nutrition in the body. Nasogastric feeding requires the use of a nasogastric feeding tube.

[0003] Nasogastric tubes come in different sizes, with thin tubes being less susceptible to damage and more prone to clogging. They are made of polyurethane or silicone. When a gastric tube is placed in the esophagus, the patient's original digestive tract physiological environment is changed, i.e., the placement of a nasogastric tube can cause the terminal esophageal sphincter to close loosely, making esophageal reflux more likely to occur. It is only used temporarily or for a short period of time for patients who are comatose or unable to swallow and eat by themselves.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example: Refer to Figure 1-4 As shown, a nasogastric feeding tube anti-drop structure comprises a hose 1, on which an inflatable component 4 for fixing at a nostril is sleeved, the inflatable component 4 comprises an inflatable ring 401 sleeved on the outside of the hose 1, the inflatable ring 401 is connected to an air pressure ball 403 through an air pipe 402, two rubber bands 6 are symmetrically connected to the hose 1 near the inflatable component 4 through a fixing component 5, the ends of the two rubber bands 6 are connected to earrings 9, and a throttling component 8 for controlling the flow rate of a nutrient solution is arranged near the fixing component 5 on the hose 1; the throttling component 8 comprises a fixing cylinder 801 sleeved on the outside of the hose 1, a threaded hole is provided on the fixing cylinder 801, and a bolt 802 that conflicts with the hose 1 is threadedly connected in the threaded hole;

[0026] Specifically, when nasogastric feeding is required for the patient, the hose 1 is inserted into the nose, the inflation ring 401 is placed at the nostrils, and the air pressure ball 403 is pressed. The air pressure ball 403 inflates the inflation ring 401 through the trachea 402, and then the inflation ring 401 is inflated to squeeze the nostrils and the nasogastric feeding tube, and then the two rubber bands 6 are pulled to hang the earrings 9 on the two ears, thereby achieving the effect of fixing nasogastric feeding tubes of different sizes. When the flow rate of the nutrient solution needs to be controlled, the bolt 802 is rotated so that the bolt 802 squeezes the hose 1, and then the flow rate of the nutrient solution is conveniently and quickly adjusted to reduce the possibility of discomfort to the patient caused by excessive flow of the nutrient solution.

[0027] Furthermore, the fixing assembly 5 includes a clamping ring 501 sleeved on the outside of the hose 1, and an anti-skid pad 502 is attached to the inner side of the clamping ring 501. A plurality of springs 503 are connected to the anti-skid pad 502, and the ends of the plurality of springs 503 are fixedly connected with gaskets 504. When the rubber band 6 needs to be fixed to the outside of the hose 1, the hose 1 is placed in the clamping ring 501, and under the elastic force of the spring 503, the gasket 504 is squeezed so that the gasket 504 contacts the hose 1, thereby fixing the hose 1.

[0028] Furthermore, one end of the hose 1 is connected to a hollow threaded column 2, a threaded cap 3 is threadedly connected to the threaded column 2, and a disinfectant cotton 10 is placed in the threaded cap 3. The disinfectant cotton 10 disinfects the nutrient solution, and the disinfectant cotton 10 can be replaced quickly and conveniently by rotating the threaded cap 3.

[0029] Furthermore, the hose 1 is also provided with an adhesive component 7, which includes two adhesive tapes 701 symmetrically fixedly connected to the hose 1, and a release paper 702 is provided on the back of the adhesive tapes 701. The adhesive tapes 701 are attached to the cheeks to improve the fixing effect of the hose 1.

[0030] Operation steps: When the patient needs to be fed through the nose, insert the hose 1 into the nose, place the inflatable ring 401 at the nostril, press the air pressure ball 403, and the air pressure ball 403 inflates the inflatable ring 401 through the trachea 402, so that the inflatable ring 401 is inflated to squeeze the nostril and the nasogastric tube, and then pull the two rubber bands 6 to hang the earrings 9 on the two ears, so as to achieve the effect of fixing nasogastric tubes of different sizes. When the flow rate of the nutrient solution needs to be controlled, the bolt 802 is rotated so that the bolt 802 squeezes the hose 1 to enter. The flow rate of the nutrient solution can be adjusted conveniently and quickly to reduce the possibility of discomfort to the patient caused by excessive flow of the nutrient solution. When the rubber band 6 needs to be fixed to the outside of the hose 1, the hose 1 is placed in the clamping ring 501. Under the elastic force of the spring 503, the gasket 504 is squeezed so that the gasket 504 contacts the hose 1, thereby fixing the hose 1. The disinfectant cotton 10 disinfects the nutrient solution. By turning the threaded cap 3, the disinfectant cotton 10 can be replaced conveniently and quickly, and the tape 701 is attached to the cheek to improve the fixing effect of the hose 1.
