[0027] like Figures 1 to 4 As shown, the nasogastric or oral feeding nutrition tube device with esophageal surface drug delivery function provided by the utility model comprises a nutrition tube 1 and a capsule tube 2, wherein: a nutrient solution channel 3 and a drug delivery channel 4 which penetrate the nutrition tube 1 are arranged in the nutrition tube 1; the nutrition tube 1 comprises a drug delivery segment tube body 5, the drug delivery segment tube body 5 is located at one end close to the stomach, a drug delivery hole 6 is opened on the drug delivery segment tube body 5, the drug delivery channel 4 is connected with the drug delivery hole 6, the drug delivery segment tube body 5 is covered with a polymer material buffer layer 7 which can permeate the drug solution, the capsule tube 2 covers the polymer material buffer layer 7, and is sleeved and installed outside the drug delivery segment tube body 5, and the capsule tube 2 is provided with micropores.

[0028] It should be noted that: the balloon tube 2 can be set within 15-40 cm from the proximal end of the stomach of the nutrition tube 1; the micropores on the balloon tube 2 include two types of pores, one is an open pore, the pore size of the balloon tube wall under natural static state is 0.1-3 mm, preferably 0.3-0.5 mm; the other is a non-open pore, the micropores of the balloon tube wall under natural static state are in a closed state, and the pores open when a certain pressure is applied to the balloon, and the drug seeps out; the two ends of the balloon tube 2 are longer than the circumferential width of the polymer material buffer layer 7; the drug outlet hole 6 can be one or two or more.

[0029] The utility model provides a nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery, comprising a nutrition tube 1 and a capsule tube 2. When the drug liquid in the drug delivery channel 4 passes through the drug delivery section tube body, the drug liquid enters the polymer material buffer layer 7 through the drug outlet hole 6, and after uniformly seeping out of the polymer material buffer layer 7, the drug liquid uniformly enters the lesion site from the micropores on the capsule tube 2. The above-mentioned drug liquid seepage process makes the drug liquid seeping out more uniformly at the distal and proximal ends of the capsule tube, thereby improving the treatment effect.

[0030] like Figure 1 and Figure 3 As shown, it also includes a positioning baffle 8 and a double-sided adhesive tape 9, and the positioning baffle 8 is attached to the upper lip in front of the nostril through the double-sided adhesive tape 9. In this embodiment, the baffle is used to fix the position of the nutrition tube 1. The positioning baffle 8 is fixed to the upper lip to avoid the disadvantage that the baffle hinders nasal breathing, thereby improving the convenience of using the nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery.

[0031] like Figure 1 As shown, the nutrition tube 1 includes a nutrient solution inlet branch 10, a drug solution inlet branch 11, and a pressure push piece 12.

When in use, a syringe or other peripheral air supply device is used to inflate the elastic rubber balloon to expand the elastic rubber balloon, and then the elastic rubber balloon relies on its own contraction to apply pressure to the liquid medicine capacity cylinder (box), thereby improving the convenience of using the nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery.

[0034] In one embodiment of the utility model, the pressure pusher 12 is a liquid medicine electric infusion pump. The liquid medicine electric infusion pump is a prior art, and any existing device that can push the medicine liquid into the medicine liquid inlet branch 11 can be used, thereby improving the convenience of using the nasogastric or oral feeding tube device with the function of esophageal surface drug delivery.

[0035] like Figure 1 As shown, it also includes a Mouphy's dropper 16 and a liquid medicine flow regulator 17, which are both installed in series between the liquid medicine inlet branch 11 and the pressure pusher 12. It should be noted that both the syringe-type and balloon-type drug delivery devices rely on flow control regulators to achieve pressure regulation of the liquid medicine flow or the balloon tube. In this embodiment, the Mouphy's dropper 16 is a prior art, which can facilitate observation of the flow rate, and the liquid medicine flow regulator 17 can facilitate adjustment of the pressure and flow rate, which is also a prior art. Any device that can adjust the pressure and flow rate can improve the convenience of use of the nasogastric or oral feeding nutrition tube device that also has the function of esophageal surface drug delivery.

[0036] In one embodiment of the utility model, the polymer material buffer layer 7 is a spunlace nonwoven fabric or a polymer foam sheet.

When the capsule tube enters the stomach, the patient's experience is better, thereby improving the convenience of using the nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery.

[0038] In one embodiment of the utility model, both ends of the capsule tube 2 are bonded and sealed to the outer wall of the medicine outlet tube 5 by a silicone rubber adhesive, so that the capsule tube 2 is more firmly installed on the outer wall of the medicine outlet tube 5, thereby improving the structural stability of the nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery.

[0039] In one embodiment of the utility model, the medicine flow regulator 17 is a knob pressurized flow regulator or a roller pressurized flow regulator. The medicine flow regulator 17 is more convenient for adjusting the medicine flow rate and can make the medicine seep out more stably and evenly, thereby improving the ease of use of the nasogastric or oral feeding tube device that also has the function of esophageal surface drug delivery.

[0040] The utility model provides a nasogastric or oral feeding nutrition tube device with the function of esophageal surface drug delivery, comprising a nutrition tube 1 and a capsule tube 2. When the drug liquid in the drug delivery channel 4 passes through the drug delivery section tube body, the drug liquid enters the polymer material buffer layer 7 through the drug outlet hole 6, and after uniformly seeping out of the polymer material buffer layer 7, the drug liquid uniformly enters the lesion site from the micropores on the capsule tube 2. The above-mentioned drug liquid seepage process makes the drug liquid seeping out more uniformly at the distal and proximal ends of the capsule tube, thereby improving the treatment effect.
