[0032] Embodiment 1:

[0033] Reference Figure 1 - Figure 6, a gastrointestinal drug delivery device with simple operation, comprises a medicine liquid tank 1, a cover body 2 is arranged on the rear side of the medicine liquid tank 1, a rear end outer wall of the medicine liquid tank 1 and a front end inner wall of the cover body 2 are both arranged with threads, the medicine liquid tank 1 and the cover body 2 are connected by threads, an observation window is arranged on one side of the outer wall of the medicine liquid tank 1, a gripping handle is fixedly connected to the other side of the outer wall of the medicine liquid tank 1, an output end of an air pressure bag 3 located on the rear side of the cover body 2 is fixedly connected to the rear side of the cover body 2, an air nozzle 4 is fixedly connected to the outer wall of the output end of the air pressure bag 3, a one-way valve sheet 5 is installed on the inner wall of the output end of the air pressure bag 3, an infusion tube is arranged on the front side of the medicine liquid tank 1, a mounting member 7 is arranged on the rear end of the infusion tube, a sealing ring 8 is fixedly connected to the rear side of the mounting member 7, and the infusion tube for conveying liquid medicine is mainly composed of an outer tube 12 and an inner tube 13, the outer tube 12 is located on the outer wall of the inner tube 13, the outer tube 12 is soft and smooth in texture to protect the esophagus of the human body, and the inner tube 13 is used to transport liquid medicine. A support portion 14 is provided on the adjacent side of the outer tube 12 and the inner tube 13. The support portion 14 is in the shape of a mesh and is made of metal iron. The mesh structure is used to support the outer tube 12 to prevent the esophagus from squeezing and reducing the diameter of the inner tube 13, thereby reducing the efficiency of infusion. The input end of the inner tube 13 is fixedly connected to the front side of the mounting member 7 and connected to the inside of the drug tank 1; the input end of the drug delivery head 6 is connected to the output end of the inner tube 13, and a liquid guide channel 10 is provided inside the drug delivery head 6. A plurality of liquid outlet holes 11 are provided on the outer wall of the drug delivery head 6, and the liquid outlet holes 11 are connected to the liquid guide channel 10;

[0034] Specifically, the cover body 2 can be removed from the medicine tank 1 by means of a thread, so that the medicine tank 1 is filled with medicine for treating the gastrointestinal tract. The observation window can be used to observe the amount of medicine in the medicine tank 1 during the process of infusion administration. The side of the one-way valve sheet 5 facing the output end is in the shape of a raised cone. When the air pressure bag 3 is squeezed, the gas in the air pressure bag 3 will exert pressure on the recessed part of the one-way valve sheet 5 to expand it, thereby allowing the gas to pass through. When the gas wants to pass through the one-way valve sheet 5 from the output end, it will be blocked by the raised pointed cone part, and pressure will be applied to it so that the pointed cone structure will support each other and avoid opening, so that the output end of the air pressure bag 3 becomes a one-way channel, and air is taken in through the air nozzle 4, rather than drawing air from the cavity of the connected medicine tank 1, to ensure the air pressure in the medicine tank 1, so as to promote the medicine to enter the infusion tube. The liquid conduit 10 inside the drug delivery head 6 is a spiral path, thereby extending the drug delivery path, and using the liquid outlet holes 11 dispersedly connected to the liquid conduit 10 to allow the drug solution to flow out from the liquid conduit 10 to be evenly released in the stomach and intestines, avoiding drug administration at the same position, thereby increasing the precision of treatment.

[0035] Embodiment 2:

[0036] As one of the optimized structural designs for Example 1, Figure 1 and Figure 4As shown, the clamping assembly includes a clamping member 9 fixedly connected to the front side of the liquid medicine tank 1, and the front sides of the mounting member 7 and the sealing ring 8 are both provided with a clamping groove, and the clamping member 9 is clamped and connected inside the clamping groove;

[0037] Specifically, the drug dispensing device has a simple structure, a simple and easy-to-use operation process, and can be used for simple and convenient medical work. The components can be disassembled and separated, so that the components can be easily replaced, and the drug dispensing device can be easily cleaned and maintained, ensuring hygiene while extending the service life, so that it meets medical regulations and hygiene standards. The card 9 has a certain elasticity, and an extension portion is provided at one end of the card 9. When the card 9 is located in the card slot, the extension portion will be connected to the edge of the card slot to fix it.

[0038] Working principle: When administering the drug, the drug liquid in the drug liquid tank 1 is filled, and then the infusion tube together with the drug administration head 6 is passed along the patient's esophagus into the patient's stomach and intestines. By squeezing the air pressure bag 3, the gas in the air pressure bag 3 will exert pressure on the depressed part of the one-way valve sheet 5 to expand it, thereby allowing the gas to pass through, increasing the air pressure in the drug liquid tank 1, thereby affecting the air pressure in the drug liquid tank and entering the inner tube 13 in the infusion tube, and then entering the liquid guide channel 10 of the drug administration head 6 along the inner tube 13. The liquid guide channel 10 follows the spiral path to extend the drug delivery path, and flows out through the dispersed and interconnected liquid outlet holes 11 of the liquid guide channel 10, and is evenly released in the stomach and intestines. When cleaning the drug dispenser, the cover body 2 can be removed from the medicine liquid tank 1 by rotating it, and the inside of the medicine liquid tank 1 can be cleaned. The clamping member 9 can be pressed to make the extended part of the clamping member 9 disengage from the edge of the clamping slot, thereby releasing the clamping member 9 fixed to the mounting member by the clamping slot, and then the connecting tube and the fixing member 7 can be removed and cleaned separately.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
