Description

Technical Field

[0001] The invention relates to the technical field of interventional drug delivery equipment, in particular to an interventional drug delivery equipment for treating atrophic gastritis. Background Art

[0002] Atrophic gastritis, also known as chronic atrophic gastritis, is a stomach disease mostly caused by Helicobacter pylori infection or unhealthy eating habits. It often presents with upper abdominal pain, fullness, belching or loss of appetite, and has a certain chance of canceration. It is a general term for many harmful factors to human health. Interventional treatment needs to be carried out under the guidance and monitoring of imaging equipment, which can accurately and directly reach the lesion without major trauma.

[0003] Western medicine has no specific treatment for atrophic gastritis. It advocates eating non-irritating food, giving gastric mucosal protectants, gastrokinetic drugs, antacids, and anti-Helicobacter pylori treatment for Helicobacter pylori-positive patients. However, these methods are not effective for wounds in the upper part of the stomach. The main reason is that after the medicine is dissolved in gastric acid, it is difficult for the medicine to have long-term effective contact with the upper part of the stomach, making it difficult for the medicine to reach the wound in the upper part of the stomach, thereby reducing the treatment effect. Existing equipment makes it difficult to accurately spray the medicine on the wound in the upper part of the stomach, and it is impossible to achieve precise drug delivery. Summary of the invention

[0004] The purpose of the present invention is to provide an interventional drug delivery device for treating atrophic gastritis, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When in use, the shell containing the medicine is pressed into the end block, and the shell is connected to the air pressure control structure, and then the threaded cap is screwed onto the end block. The threaded cap squeezes the shell into the end block through the limit block, so that the shell and the air pressure control structure are tightly abutted. Then the personnel inserts the insertion tube into the patient's esophagus, and the insertion tube drives the end block to move in the patient's esophagus through the deflection mechanism. During this period, the personnel obtains the picture taken by the camera through the control module. The deflection mechanism adjusts the direction of the shell discharge port by driving the end block to deflect, so that the shell discharge port is facing the stomach wound. Then the air pressure control structure inflates the shell, and the pressurized discharge part driven by air pressure is separated from the shell discharge port. Under the blowing of high-speed airflow, the medicine in the shell is blown toward the stomach wound, thereby completing the drug administration operation. When different types of medicines are needed for drug administration, the replacement of medicines is completed by actively replacing the shell and the pressurized discharge part, which is convenient and quick. The present invention directly delivers the medicine to the stomach wound by directly reaching the stomach through the esophagus and spraying the medicine on the stomach wound, thereby achieving accurate medicine delivery and avoiding excessive use of the medicine.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0024] An air pressure control structure 3 installed in the box 1;

[0025] The insertion medication structure 4 connected to the box body 1 includes an insertion tube 5 fixedly connected to the box body 1. The insertion tube 5 is a flexible hose. The insertion tube 5 provides protection for the live wires used for communication and control by covering. The end of the insertion tube 5 away from the box body 1 is fixedly installed with a deflection mechanism 6. The deflection mechanism 6 is connected to a pressurized medicine blowing mechanism 7. The pressurized medicine blowing mechanism 7 includes an end block 8 connected to the air pressure control structure 3. The end block 8 is connected to the deflection mechanism 6. A shell 9 movably connected to the air pressure control structure 3 is movably installed in the end block 8. The shell 9 is used to store therapeutic drugs, and a pressurized discharge part 10 is installed in the shell 9. When the air pressure control structure 3 inflates the shell 9, the pressurized discharge part 10 driven by the air pressure is separated from the discharge port of the shell 9. A plurality of groups of cameras 11 are fixedly installed on the end block 8, and the cameras 11 are communicatively connected with the control module 2. A threaded cover 12 is threadedly connected to the end block 8, and a hole adapted to the camera 11 is provided on the threaded cover 12. The camera 11 is communicatively connected with the control module 2, and a limit block 13 movably connected to the shell 9 is fixedly installed on the threaded cover 12.

[0026] When in use, the shell 9 filled with medicine is pressed into the end block 8, and the shell 9 is connected to the air pressure control structure 3, and then the threaded cover 12 is screwed onto the end block 8. The threaded cover 12 squeezes the shell 9 into the end block 8 through the limit block 13, so that the shell 9 and the air pressure control structure 3 are tightly abutted. Then the personnel inserts the insertion tube 5 into the patient's esophagus, and the insertion tube 5 drives the end block 8 to move in the patient's esophagus through the deflection mechanism 6. During this period, the personnel obtains the picture taken by the camera 11 through the control module 2, and the deflection mechanism 6 The driving end block 8 is deflected to adjust the direction of the discharge port of the shell 9 so that the discharge port of the shell 9 is facing the stomach wound, and then the air pressure control structure 3 inflates the shell 9, and the pressurized discharge part 10 driven by air pressure is separated from the discharge port of the shell 9. Under the blowing of high-speed airflow, the medicine in the shell 9 is blown to the stomach wound, thereby completing the drug administration operation. When different kinds of medicines are needed for drug administration, the replacement of the medicines is completed by actively replacing the shell 9 and the pressurized discharge part 10, which is convenient and fast. The present invention directly reaches the stomach through the esophagus and sprays the medicine on the stomach wound, thereby completing the direct drug administration to the stomach wound, achieving accurate drug delivery, and avoiding excessive use of medicines.

After the control valve is opened, the pressurized air in the pressurized gas cylinder 15 passes through the gas cylinder joint 14, the control valve, the hose 16, the first connector 17, and the second connector 18 in sequence, and finally the air enters the shell 9 to pressurize the inner cavity of the shell 9.

[0028] In one case of this embodiment, the deflection mechanism 6 includes a connection seat 19 fixedly connected to the insertion tube 5, the connection seat 19 is fixedly connected to a ball seat 20, a plurality of groups of first electromagnets 21 are fixedly mounted on the ball seat 20, a sphere 22 is rotatably connected to the ball seat 20, a plurality of groups of connecting strips 23 are fixedly mounted between the sphere 22 and the end block 8, a second electromagnet 24 coupled to the first electromagnet 21 is fixedly mounted on the end block 8, the second electromagnet 24 is used to drive the end block 8 to deflect, and the first electromagnet 21 and the second electromagnet 24 are both communicatively connected to the control module 2. Through the magnetic attraction of the first electromagnet 21 to the second electromagnet 24 and the control of the magnetic field strength on the first electromagnet 21 and the second electromagnet 24 at different positions, the distance between the first electromagnet 21 and the second electromagnet 24 at different positions changes, thereby controlling the deflection angle of the end block 8 relative to the ball seat 20.
