FOOD REFLUX REDUCING TWO-PIECE NASOGASTRIC TUBE

Abstract

A food reflux reducing two-piece nasogastric tube includes a first tube body and a second tube body. The first tube body has a first connector on one end, and a protrusion edge on an outer side of the first connector in adjacent to the first positioning portion. The first connector has a through hole having a seal portion in adjacent to the first positioning portion. The seal portion has a cross break. A convex portion is on an inner edge of the through hole between the seal portion and the first positioning portion. The second tube body has one end provided with a second connector and an insertion combination tube extending therefrom. Two elastic arms extend from an outer side of the second connector and comprise a hook portion respectively. Thus, the second tube body is efficiently connected with and removed from the first tube body.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

[0018] Referring to FIG. 1 to FIG. 3, the present invention provides a food reflux reducing two-piece nasogastric tube, comprising a first tube body 10, a second tube body 20, and a fixing device 30.

[0019] The first tube body 10 comprises a first connector 11 disposed on one end thereof, and an insertion portion 12 disposed on another end thereof. A first positioning portion 111 is disposed on one end of the first connector 11 away from the first tube body 10. A ring-shaped protrusion edge 112 is disposed on an outer side of the first connector 11 in adjacent to the first positioning portion 111. The first connector 11 comprises a through hole 113 formed in an axial direction and connected with the first tube body 10. The through hole 113 comprises an elastic seal portion 114 disposed in adjacent to the first positioning portion 111, and the seal portion 114 is provided with a cross break 1141 which is normally in a sealing status. The inner edge of the through hole 113 comprises a ring-shaped convex portion 1131 disposed between the seal portion 114 and the first positioning portion 111.

[0020] The second tube body 20 comprises an irrigation portion 21 disposed on one end and a second connector 22 disposed on another end. A second positioning portion 221 is disposed on one end of the second connector 22 away from the second tube body 20, and an insertion combination tube 222 extends from the second positioning portion 221., wherein the insertion combination tube 222 is connected with the second tube body 20. The second connector 22 comprises two elastic arms 223 extending from an outer side of the second connector 22 toward the insertion combination tube 222, with a hook portion 2231 disposed on a distal end of each of the two elastic arms 223. Each of the two elastic arms 223 comprises a press portion 2232 which is disposed in adjacent to the second connector 22 and extending toward the second tube body 20, respectively. When the two press portions 2232 are pressed, the press portions 2232 drive the two elastic arms 223 to open.

[0021] The fixing device 30 comprises a fixing member 31, an adherence member 32, and a connection member 33. The fixing member 31 comprises a clamp ring 311, which detachably clamps the first tube body 10 in adjacent to or on the first connector 11 for providing a fixing effect. The adherence member 32 is able to be adhered on the nose of the patient. The connection member 33 is pivotally and adjustably connected between the fixing member 31 and the adherence member 32, so as to improve the fixing effect of the first tube body 10 which is retained in the patient body.

[0022] During the irrigation feeding operation, referring to FIG. 4, the second connector 22 is inserted into the through hole 113 of the first connector 11 through the insertion combination tube 222, such that the insertion combination tube 222 expands the cross break 1141, and the outer periphery of the insertion combination tube 222 tightly abuts against the convex portion 1131, thereby forming a sealing status. Also, with the second positioning portion 221 abutting against the first positioning portion 111, and the hook portion 2231 of the two elastic arms 223 hooking the protrusion edge 112, the second connector 22 is connected with the first connector 11, and the second tube body 20 is connected with the first tube body 10, such that insertion portion 12 of the first tube body 10 passes from the nasal cavity through the esophagus into the stomach of the patient, allowing a food fluid to be provided from a feeding syringe into the irrigation portion 21, and accordingly enter the stomach of the patient for supplying necessary nutrition.

[0023] When the irrigation feeding operation is complete, referring to FIG. 5 to FIG. 8, the two press portions 2232 are pressed to open the two elastic arms 223, such that the hook portion 2231 of the elastic arms 223 leaves the protrusion edge 112, and the second connector 22 of the second tube body 20 is disassembled from the first connector 11 of the first tube body 10. When the second connector 22 of the second tube body 20 is removed, the cross break 1141 of the first connector 11 is automatically restored to the sealing status by the elasticity of the seal portion 114, thereby preventing external matters from entering the first tube body 10 to cause infection, and also preventing the reflux of food residue in the first tube body 10. Also, with only the first tube body 10 being retained in the patient body, the aesthetic appearance and comfort of the patient after the installation of the nasogastric tube is improved, and the possibility of the nasogastric tube being accidentally pulled is significantly reduced.

[0024] With the foregoing configuration, the present invention achieves following advantages.

[0025] Regarding the food reflux reducing two-piece nasogastric tube of the present invention, when the insertion combination tube 222 of the second connector 22 is inserted into the through hole 113 of the first connector 11 for combination, the insertion combination tube 222 expands the cross break 1141, and the outer periphery of the insertion combination tube 222 tight abuts against the convex portion 1131; when the second tube body 20 is removed from the first tube body 10, the cross break 1141 of the first connector 11 is automatically sealed. Therefore, the present invention significantly increases the convenience of usage, and greatly reduces the discomfort of patient and the situation of food reflux. Also, the conditions of the cover falling or the user forgetting to put on the cover are avoided.

[0026] Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
