Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and provides a cleaning device for upper digestive tract bleeding. Background Art

[0002] Acute upper gastrointestinal bleeding is one of the common critical diseases in gastroenterology. It often presents with hematemesis and melena as the main clinical manifestations. The condition is serious and has a high mortality rate. According to the cause, it can be divided into non-varicose bleeding and varicose bleeding. In recent years, with the continuous development of treatment technology, its incidence has shown a significant downward trend, but its related mortality rate is still as high as 2-10%, and about 33% of patients will experience recurrent upper gastrointestinal bleeding, which is an increasingly serious public health problem in my country. Early endoscopic examination and treatment can significantly reduce the mortality rate and rebleeding rate of upper gastrointestinal bleeding. Therefore, early endoscopic examination and treatment of acute upper gastrointestinal bleeding are of great significance to public health.

[0003] Upper gastrointestinal endoscopy is an important means of diagnosis and treatment for patients with acute upper gastrointestinal bleeding. In patients with acute upper gastrointestinal bleeding, early endoscopy (performed within 24 hours) after hemodynamic resuscitation can not only accurately identify the bleeding focus, but also guide further treatment based on endoscopic grading. However, in clinical practice, when performing emergency endoscopy for acute upper gastrointestinal bleeding, the endoscopic field of view is often limited by the large amount of blood clots at the fundus of the patient's stomach, making it impossible to find the bleeding point, which significantly reduces the efficiency of early endoscopic hemostasis treatment. At the same time, the areas covered by blood clots are often high-incidence areas of gastric varicose bleeding and Dieulafoy's disease, which significantly increases the risk of recurrent bleeding. Therefore, how to better clean the blood clots at the fundus of the stomach and improve the treatment efficiency of early endoscopy is a problem that needs to be solved clinically.

[0004] At present, the specific method of how to deal with blood clots in the fundus of the stomach during early endoscopic examination of acute upper gastrointestinal bleeding is still unclear. However, the guidelines for the diagnosis and treatment of acute non-varicose upper gastrointestinal bleeding suggest that intravenous infusion of erythromycin before early endoscopic examination can promote gastric motility, thereby prompting the blood to be quickly discharged into the intestine. However, it has been found in clinical practice that this solution can only allow part of the blood to enter the intestine, and still cannot allow the blood clots that have already coagulated into clots to enter the intestine. And direct gastroscopic suction can already solve the problem of fresh blood accumulation in the fundus of the stomach. However, due to the size of the diameter of the gastroscope's own cavity, direct suction of blood clots by the gastroscope will cause blockage of the suction hole. Therefore, how to directly clean blood clots in the fundus of the stomach during endoscopic examination is still a problem that needs to be solved urgently in clinical practice.

The above scheme can effectively remove blood clots and realize endoscopic examination and treatment.

[0022] In the present embodiment, the water outlets 3 are arranged in a single row of three to five at intervals. The water outlets arranged at intervals can prevent the spraying from being too concentrated, thereby avoiding excessive flushing and damage to the blood-accumulated tissue.

[0023] In this embodiment, the ferrule 2 and the tube body 1 adopt an integrated structure, and the material is medical silicone; in this way, it can be ensured that the two are a whole, and the medical silicone as a material has good biocompatibility and durability, and can provide good comfort and safety during use.

[0024] In this embodiment, the ferrule 2 is tightly matched with the endoscope, and the front end of the ferrule is provided with a constriction to stop the endoscope. In this way, the connection between the ferrule and the endoscope can be ensured to be firm, and loosening or falling off can be avoided during operation. At the same time, the constriction at the front end of the ferrule can stop the endoscope, prevent the endoscope from being over-inserted, and ensure the stability and safety of the endoscope.

[0025] In this embodiment, the cross section of the tube body 1 except the end is in a U-like or C-like shape, and the concave surface is located on the outer wall of the tube body on the side where the ferrule is located, and a tape for bonding the endoscope wire is provided on the concave surface. In this way, the endoscope wire can extend along the concave surface of the tube body, which helps to reduce the cross-sectional diameter or area of ​​both, and is easy to operate. The position of the concave surface and the setting of the tape make the tube body attached to the endoscope wire and not easy to fall off or loosen.

[0026] In this embodiment, the ferrule 2 protrudes from the front end of the tube body 1. This design allows the two to have a staggered structure to prevent the suction port from sucking the gastric mucosa.

[0027] In the present embodiment, a spiral cone-shaped slitting wire 6 is arranged in the suction port 4 and behind the slitting wire 5, and the cone top of the slitting wire 6 is connected to the intersection of the slitting wire 5, and the cone bottom is connected to the tube body 1.

The spiral cone structure of the slitting wire can further increase the cutting force, making the blood clot easier to be dispersed and cut, which is conducive to suction.

[0028] Usage: An endoscope is embedded and fixed on the ferrule 2 on the outer wall of the front end of the tube body 1, and the concave surface of the tube body 1 is bonded to the endoscope wire, so that the tube body 1 is perfectly attached to the endoscope and enters the stomach together with the endoscope, and the water injection pipeline 8 and the suction pipeline 7 in the tube body 1 are respectively connected to the external water injection pump and the suction pump. During the operation of the endoscope, the suction port 4 of the tube body 1 is immersed in the accumulated blood and blood clots, and the suction pump is turned on to remove the accumulated blood and blood clots in the stomach from the stomach, and the blood clots sucked into the suction port can be dispersed and cut by the dividing wire 5 and the slitting wire 6 for better suction. During this period, if there is a foreign body in the stomach (such as food) that covers the accumulated blood or blood clots, the water injection pump can be turned on, and the water outlet sprays the injection fluid to push away the foreign body, so as to attract the accumulated blood and blood clots.
