Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an indwelling device for direct drug administration and treatment of gastric ulcers in the gastroenterology department. Background Art

[0002] The Department of Gastroenterology includes the Department of Gastroenterology and the Department of Gastroenterology and is a clinical department set up by hospitals at all levels for the diagnosis and treatment of digestive system diseases. The diseases treated include diseases of the esophagus, stomach, intestines, liver, gallbladder, pancreas, peritoneum, mesentery, omentum and other organs. Among them, gastric ulcer is one of the treatment scopes of the Department of Gastroenterology. Gastric ulcer is a common digestive disease, most commonly referring to ulcers on the inner wall of the stomach. Its main cause is long-term Helicobacter pylori infection and excessive use of non-steroidal anti-inflammatory drugs, which cause damage to the gastric mucosa. The disease is typically manifested by symptoms such as stomach pain, decreased appetite, and weight loss. In severe cases, gastric perforation or gastric bleeding may occur. For many years, gastric ulcer has been a difficult problem in the medical community. In the prior art, oral administration is mainly used to treat gastric ulcers, but oral administration has the disadvantages of slow absorption and unclear targeting. With the increasing number of gastric ulcers in the Department of Gastroenterology, the requirements for the treatment facilities of gastric ulcers in the Department of Gastroenterology have also increased, and a therapeutic indwelling device that directly administers drugs to the location of gastric ulcers has been born.

[0003] The Chinese Patent Network discloses a "gastric tube for treating gastric ulcer", with the announcement number CN204890900U, which comprises an endoscope (3), a cleaning tube (7), and a liquid inlet and outlet tube (9). The ends of the cleaning tube (7) and the liquid inlet and outlet tube (9) are inserted into the buffer (2), the end of the endoscope (3) passes through the buffer (2), and the end is connected to a visual screen (1); the buffer (2) is connected to an air inlet tube (12), and the other end of the air inlet tube (12) is connected to a pressure device (13); the buffer (2) is equipped with a pressure gauge (11); the upper part of the endoscope (3) is equipped with a photosensitive lamp (4); the top of the endoscope (3) is equipped with a camera; the top of the cleaning tube (7) is equipped with a hard brush (6); the top of the liquid inlet and outlet tube (9) is provided with a gun head (8); the liquid inlet and outlet tube (9) is provided with an anti-backflow clamp (10). First, the liquid inlet and outlet tube is filled with liquid containing medicine for treating gastric ulcer, and then the endoscope, cleaning tube and liquid inlet and outlet tube are simultaneously inserted into the stomach of the human body through the esophageal tube, and the anti-backflow clamp is located outside the mouth; the photosensitive lamp starts to emit light because the pipeline inside the stomach is weaker than the fluorescent lamp, illuminating the environment inside the stomach, and the camera collects information inside the stomach and transmits it to the visual screen, through which the ulcer surface inside the stomach can be observed; the cleaning brush is moved, and the ulcerated part of the ulcer surface is brushed off with a hard brush; then the liquid inlet and outlet tube is moved so that the gun head is aimed at the ulcer surface that has been cleaned by the brush, the anti-backflow clamp is opened, and the pressure device is made to pressurize the liquid in the liquid inlet and outlet tube so that it can be sprayed onto the ulcer surface to apply medicine to the ulcer surface; after the application of medicine is completed, that is, the liquid in the liquid inlet and outlet tube is completely released, the pressure device is operated again to suck the ulcerated dirt washed out of the stomach into the liquid inlet and outlet tube through the gun head, and after the operation is completed, the endoscope, cleaning tube and liquid inlet and outlet tube can be taken out.

[0004] The ulcerated part of the ulcer surface is brushed out preferentially with a brush. After the medicine is applied, it is sucked into the liquid inlet and outlet tube through the gun head with the help of a pressure device. Since the ulcerated dirt is not located at the position where the liquid inlet and outlet tube is aimed when the brush is brushing the ulcerated part of the ulcer surface, the amount of ulcerated dirt attracted subsequently is limited, and the remaining ulcerated dirt will increase the risk of infection in other parts of the stomach, delaying or hindering the recovery effect.

The adjustment component changes the inclination angle of the outflow tube 104 to clean the ulcerated part of the ulcer surface. At the same time, the adjustment component can change the inclination angle of the outflow tube 104 to aim at the ulcerated dirt, thereby achieving effective attraction of the ulcerated dirt to reduce the residue of the ulcerated dirt; when the adjustment component is working, the adjustment motor 109 in the inclined direction rotates forward, thereby realizing the winding action of the adjustment motor 109 on the connecting rope 108 on its output shaft, and the other adjustment motors 109 rotate in the opposite direction, thereby realizing the winding action of the other adjustment motors 109 on their output shafts The connecting rope 108 on the outer cover realizes the unwinding action. When rewinding, the outflow tube 104 at that angle will be pulled, and when unwinding, it is adaptively adjusted to adapt to the tilt angle. A timer 130 can be set in the shell 100.

[0037] Specifically, the working principle of a direct drug delivery treatment device for gastric ulcer in the gastroenterology department provided in this application is: Put the drug powder and drug liquid into the drug storage cavity 101 through the drug inlet hole 102 in advance, and when mixing is required, start the stirring motor 121 to rotate the driving roller 122, and then drive the hollow tube 118 to rotate the stirring plate 119 through the transmission belt 123, so that the stirring plate 119 can stir the drug in the drug storage cavity 101; Then, the outflow tube 104 together with the drug delivery tube 103 is inserted into the stomach of the human body through the esophageal tube, and the information inside the stomach is collected by the camera 107 and displayed on the display screen 124. The adjustment component can be used to change the inclination angle of the outflow tube 104 to clean the ulcerated part of the ulcer surface. At the same time, the adjustment component can be used to change the inclination angle of the outflow tube 104 to align with the ulcerated dirt, thereby achieving effective suction of the ulcerated dirt to reduce the residue of the ulcerated dirt; When the adjusting component is working, the adjusting motor 109 in the tilting direction rotates forward, thereby realizing the winding action of the adjusting motor 109 on the connecting rope 108 on its output shaft, while the other adjusting motors 109 rotate in the opposite direction, thereby realizing the unwinding action of the other adjusting motors 109 on the connecting rope 108 on its output shaft. When winding, the outflow tube 104 of the angle will be pulled, and when unwinding, adaptive adjustment is made to adapt to the tilting angle. A timer 130 can be set in the shell 100. Since the rotation speed of the adjusting motor 109 is fixed, and the winding length, unwinding length and the tilting angle of the outflow tube 104 are proportional, the tilting angle can be changed by adjusting the rotation speed of the adjusting motor 109, and the indication direction of the outflow tube 104 can be adjusted by making the adjusting motors 109 in different directions rotate forward. After cleaning is completed, the speed regulating motor 114 is started, and the rotating plate 113 is driven to rotate through the rotating rod 115. The overlapping range of the No. 1 hole 116 and the No. 2 hole 117 is adjusted according to actual conditions to achieve the speed regulation effect of the liquid medicine. The liquid medicine will flow through the dosing tube 103 and the outflow tube 104 under the action of gravity to directly administer the medicine to the ulcer surface.
