Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-blocking nasogastric tube. Background Art

[0002] The nasojejunal feeding tube placement is a technique for enteral nutrition infusion through nasogastric feeding, which is applicable to patients with symptoms such as dysphagia and disturbance of consciousness who are unable to eat. In such situations, the gastric tube is manually inserted into the esophagus through the nasal cavity. First, the food is mashed with a grinder, and a large syringe is connected to the large food injection port below the gastric tube connector. After being firmly connected, the piston of the manual pressure push rod is used to inject water, food, and liquid medicine into the patient's stomach to help patients who cannot swallow independently provide water and food, and maintain the body's metabolism, weight, and nutrition. If the food or liquid given through the nasogastric tube is too thick, such as mashed food that is not fully stirred and contains granular solids, it is very likely to deposit in the tube, resulting in blockage.

[0003] In the prior art, in order to prevent the tube from being blocked when the patient is being infused with fluid food, the common method is: after injecting food into the patient's stomach through the nasogastric tube, a small amount of warm water is injected to wash the inner wall of the tube body through the water flow, so as to prevent the inside of the tube from being blocked. However, if the injection speed of the warm water is too fast or the injection amount is too much, it will stimulate the nasopharynx, causing discomfort or reflexive coughing in the patient. If the patient is in a semi-conscious or confused state, the warm water is easily inhaled into the respiratory tract, resulting in lung infection. Content of the Utility Model

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] An embodiment of the present invention provides an anti-blocking nasogastric tube, which includes a hose 1 for transporting liquid food and medicine, and also includes a connecting fitting 3 and a funnel-shaped connecting tube 4. A vertical connecting piece 12 and an annular connecting piece 11 are arranged inside the hose 1. The vertical connecting piece 12 fits and moves on the inner wall of the hose 1, and its length is the same as that of the hose 1. The annular connecting piece 11 is fixedly connected to one side of the vertical connecting piece 12. Among them, a plurality of annular connecting pieces 11 with the same size and equal spacing are connected to the vertical connecting piece 12. The vertical connecting piece 12 and the annular connecting piece 12 are made of a material that is relatively soft but has a certain toughness. When the two slide inside the hose 1, they fit on the inner wall of the hose 1, and during the sliding process, they can smoothly push the residues on the inner wall of the hose 1. One end of the hose 1 is connected to the connecting fitting 3. Slide grooves 13 with the same size are respectively arranged on both sides of the connecting fitting 3. Refer to the attached Figure 4 As shown, a clamping groove 15 is arranged below the inside of the connecting fitting 3. The funnel-shaped connecting tube 4 is composed of a connecting tube 16, a slider 9, and a clamping block 14. One end of the connecting tube 16 is movably connected to the inside of the connecting fitting 3. Among them, one end of the connecting tube 16 is fixedly connected to one side of the vertical connecting piece 12. The slider 9 is fixedly connected to both sides of the connecting tube 16. Among them, the slider 9 is slidably connected to the inside of the slide groove 13. By pinching the sliders 9 on both sides of the connecting tube 16 with hands and pulling up and down, the connecting tube 16 drives the vertical connecting piece 12 and the annular connecting piece 11 to slide up and down accordingly. A clamping block 14 is connected below the connecting tube 16. The clamping block 14 is snap-fitted with the clamping groove 15. The clamping block 14 is made of a rubber material with a certain elasticity. Among them, the size of the clamping block 14 is adapted to the size of the clamping groove 15.

[0023] During use, after the hose 1 is implanted into the stomach through the nasal cavity, the patient needs to receive liquid medicine treatment and eat normally. The food is crushed into a fluid state and enters from one end of the funnel-shaped connecting tube 4. During the process of the food flowing through the hose and reaching the stomach, it is easy for some food to remain on the tube wall and cause blockage. During or after feeding, pinch the sliders 9 on both sides of the connecting tube 16 with fingers and gently slide them back and forth. During the process of the connecting tube 16 being slid, it drives the vertical connecting piece 12 and the annular connecting piece 11 to move inside the hose 1. Among them, the outer surfaces of the vertical connecting piece 12 and the annular connecting piece 11 are attached to the inner wall of the hose 1. Without affecting the insertion of the hose 1 into the human body, they have a certain toughness and can cooperate with the connecting tube 16 at one end to move. Multiple annular connecting pieces 11 with equal spacing are arranged on one side of the vertical connecting piece 12. Therefore, when the annular connecting piece 11 moves, it can contact the blockage and push it to slide along the direction of the hose 1 connecting to the stomach, and help the liquid food enter the patient's stomach more quickly along the inside of the pipeline. After confirming that there is no blockage, the funnel-shaped connecting tube 4 is reset, so that the latch 14 is engaged and fixed with the card slot 15

[0024] Further, a liquid food inlet 5 is provided at one end of the funnel-shaped connecting tube 4 to convey food into the funnel-shaped connecting tube 4. A liquid food inlet plug 6 is fixedly connected to one end of the funnel-shaped connecting tube 4. Among them, the size of the liquid food inlet 5 is adapted to the size of the liquid food inlet plug 6

[0025] After the medical staff crush the liquid food into a paste, they aim a syringe with a larger needle hole at the liquid food inlet 5, and the food flows along the pipeline into the inside of the hose 1. After the food is completely conveyed, the liquid food inlet plug 6 is covered on the liquid food inlet 5. Since the size of the liquid food inlet plug 6 is adapted to the size of the liquid food inlet 5, the liquid food inlet 5 can be completely sealed to prevent air from entering the funnel-shaped connecting tube 4, resulting in flatulence in the patient and affecting the smooth flow of food

[0026] Further, a liquid medicine inlet 8 is provided in the middle of the liquid food inlet plug 6. A liquid medicine inlet plug 7 is connected to one side of the liquid food inlet plug 6. The size of the liquid medicine inlet 8 is adapted to the size of the liquid medicine inlet plug 7

[0027] When the liquid food inlet plug 6 is plugged, the liquid medicine inlet plug 7 is opened. The medical staff aim a syringe with a smaller needle hole at the liquid medicine inlet 8 and convey the liquid medicine into the funnel-shaped connecting tube 4 from the inlet. The liquid medicine flows along the pipeline into the inside of the hose 1. By providing a smaller liquid medicine inlet 8 on the liquid food inlet plug 6, it is not necessary to open the funnel-shaped connecting tube 4 every time when administering medicine, effectively preventing external air and dust impurities from entering the hose 1

[0028] Furthermore, the other end of the hose 1 is provided with a plurality of fluid outlets 2 that are the same in size and equally spaced. The liquid medicine and liquid food input from the funnel-shaped connecting pipe 4 pass through the interior of the hose and finally reach the fluid outlets 2, and flow into the patient's stomach through the fluid outlets 2.

[0029] The fluid outlets 2 provided at the tail of the hose 1 are the same in size and spacing, reducing the discomfort generated during the feeding of the patient. The design of the holes relieves pressure on the patient and keeps the patient breathing smoothly.

[0030] Furthermore, the other end of the hose 1 is fixedly connected with a blunt head 10, and the surface of the blunt head 10 is arc-shaped and relatively smooth.

[0031] When the patient needs to implant the hose through the nasal cavity, first insert the end of the hose 1 with the blunt head 10 into the nasal cavity. Due to the smooth appearance and the design with a certain hardness of the blunt head 10, the discomfort of the patient can be minimized as much as possible during the process of the hose 1 entering the patient's body. Similarly, the resistance during entry is also reduced, and the hose 1 can enter the patient's stomach faster.

[0032] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
