Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, in particular to a novel gastric tube. Background Art

[0002] Gastric tubes are used to deliver necessary water and food to patients who cannot swallow in special circumstances. Gastric tubes are divided into orogastric tubes and nasogastric tubes. The orogastric tube is about 45 cm long and can be inserted 35 to 40 cm through the mouth when used. The gastric tubes used in the prior art are prone to blockage due to dietary residues, insufficient drug grinding, and improper operation of medical staff.

[0003] The patent announcement number is CN213431782U, and the authorization announcement date is June 15, 2021. It is a new type of gastroenterology anti-blockage gastric tube, including a gastric tube body, one end of the gastric tube body is equipped with a guide port, one side of the guide port is provided with a plug, one side of the gastric tube body is provided with a flow feeding port, one end of the gastric tube body is equipped with a protective head, and the inside of the gastric tube body is provided with an anti-blockage structure; impurities are filtered through the filter layer, dilution layer, adsorption layer and precipitation layer in the anti-blockage structure. Although this structure can prevent large particles of fluid from flowing into the patient's body when in use, large particles of fluid are easy to block the filter layer, and its anti-blockage structure is small and cannot provide significant improvement. Patent publication number CN101239218A is a double-lumen gastric tube, the main lumen and the auxiliary lumen are connected at the head, so as to switch between the continuous suction system and the negative pressure ball suction. When the main lumen is blocked, the auxiliary lumen is used for flushing to keep the gastric tube and the stomach unobstructed; however, after the gastric tube is inserted into the stomach, its end will lean against the stomach wall, and the flushing and suction during the gastric lavage process can easily damage the gastric mucosa. In addition, the existing gastric tube scale is particularly easy to rub off, and the scale line is often not found when checking. Utility Model Content

[0004] In order to solve the shortcomings in the prior art, the utility model provides a novel gastric tube which is anti-blocking and anti-misaspiration and has clear scale markings on the outside of the tube.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A novel gastric tube, wherein the front end of the gastric tube is provided with a plurality of through holes of different apertures, the front end cross section of the gastric tube is transitioned from a circular tube to an ellipse, the short diameter of any elliptical cross section is not less than the diameter of the circular tube, and the front end of the gastric tube with the corresponding elliptical cross section is provided with an inflation ring arranged around its outer wall surface; the rear end tube body of the gastric tube is arranged as an internal threaded connector, and a sealing cover is sleeved on the internal threaded connector.

[0007] Preferably, the maximum value of the long diameter of the elliptical cross section is 2-2.5 times the diameter of the circular tube.

[0008] Preferably, a heart valve is provided on one side of the gastric tube body close to the internal threaded connector.

[0009] Preferably, the stomach tube is printed with a ruler along the outer surface of the tube body, and a layer of glue is adhered to the outer surface of the stomach tube body corresponding to the position of the ruler.

[0010] Preferably, the adhesive layer is arranged to avoid the through hole.

[0011] Preferably, the outer side wall of the blocking cover is connected to the rear end of the gastric tube via a colloid connecting rod.

[0012] Preferably, a branch tube connected to the stomach tube is provided on the tube body at the rear end of the stomach tube near the internal threaded connector, and the free end of the branch tube is configured as a trumpet-shaped opening.

[0013] The beneficial effects of the utility model are:

[0014] The head of the gastric tube of the utility model is designed to be an elliptical trumpet shape with gradually increasing diameter through the stomach, so as to expand the opening area; at the same time, the gas-filled ring on the outer wall surface is combined to keep the three-dimensional shape, so as to avoid the occurrence of port folding, wall sticking, etc. The gastric tube also adheres a transparent layer of the same material as the gastric tube to the outer layer of the scale line, so as to avoid the scale line from fading due to friction during long-term use.

[0017] The following is a further description of the specific implementation of the structural schematic diagram of a novel gastric tube of the utility model in combination with the embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model; ordinary technicians in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the utility model, so all equivalent technical solutions also belong to the scope of the utility model, and the patent protection scope of the utility model should be defined by each claim.

[0018] Example

[0019] Figure 1 A schematic structural diagram of an implementation scheme of a novel gastric tube of the utility model is shown.

[0020] This embodiment is a new type of gastric tube, wherein the front end of the gastric tube 1 is provided with a plurality of through holes 2 with different apertures, and the cross section of the front end 10 of the gastric tube 1 is transformed from a circular tube to an ellipse, and the short diameter of any of the ellipse cross sections is not less than the diameter of the circular tube, and the front end 10 of the gastric tube 1 corresponding to the ellipse cross section is provided with an inflatable ring 11 arranged around its outer wall surface; the head is designed to be an elliptical trumpet with a gradually increasing diameter to expand the opening area; and at the same time, the inflatable ring on its outer wall surface is combined to keep it in a three-dimensional shape to avoid the occurrence of port folding, wall adhesion, etc. In a further limited scheme, the maximum value of the long diameter of the ellipse cross section is 2-2.5 times the diameter of the circular tube.

[0021] The rear end tube body of the stomach tube 1 is provided with an internal thread connector 12 with an internal thread 19, and a plugging cover 13 is sleeved on the internal thread connector 12. The plugging head diameter at the front end of the plugging cover is slightly larger than the minimum diameter of the internal thread, so that it is tightly plugged. A heart valve 14 is provided on one side of the stomach tube 1 tube body close to the internal thread connector 12, and the heart valve structure can adopt the existing conventional structure.

[0022] The stomach tube 1 is printed with a scale 3 along the outer surface of the tube, and a layer of adhesive 15 is adhered to the outer surface of the stomach tube 1 corresponding to the position of the scale 3. Figure 2 As shown, the adhesive layer can be made by covering with a hot melt adhesive layer after printing the scale. The adhesive layer 15 is arranged to avoid the through hole 2, and the scale can also be marked after the through hole position.

[0023] The outer wall of the blocking cover 13 is connected to the rear end of the gastric tube 1 through a colloid connecting rod 16. A branch tube 18 connected to the gastric tube 1 is provided on the tube body near the internal thread connector 12 at the rear end of the gastric tube 1. The free end of the branch tube 18 is set as a trumpet-shaped opening 180 to accommodate syringes of different sizes; the branch tube is used to suck liquid. The heart valve 14 is provided at the rear end of the connection between the branch tube and the gastric tube.

[0024] The gastric tube of the utility model is inserted into the stomach when in use. Since an inflation ring is arranged at the insertion head of the gastric tube, damage to the gastric mucosa caused by gastric lavage is avoided. The diameter of the head of the gastric tube increases from small to large, thereby reducing the probability of the gastric tube being blocked.
