Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a circulating blood clot suction system. Background Art

[0002] Esophageal and gastric varicose bleeding is a difficult treatment procedure under digestive endoscopy. Generally, it can be treated with three-chamber two-balloon tube compression hemostasis, or endoscopic band ligation therapy, esophageal varicose vein sclerosant injection and tissue adhesive. If conservative treatment is not satisfactory, intrahepatic portosystemic shunt can also be used for treatment.

[0003] Injection, electrocoagulation and ligation under digestive endoscopy are currently the most intuitive and widely used. Due to the large amount of bleeding and violent bleeding from varicose veins in the digestive tract, large areas of blood clots are often formed. Blood clots often have a large amount of fibrous tissue, which is difficult to remove by suction through the forceps channel of the endoscope. Failure to remove the blood clot means that the bleeding point cannot be found, and hemostasis cannot be performed.

[0004] The existing method of dealing with blood clots is to connect a gastric tube to a suction tube and pass it into the stomach, and then absorb the blood clot through the suction tube under observation of the gastric tube. However, under normal conditions, the space in the stomach is small. After the blood clot is absorbed by the suction tube, the air in the stomach is reduced, making it more difficult to observe the stomach, which is not convenient for eliminating the blood clot.

[0005] Therefore, we proposed a circulating blood clot aspiration system to solve the above problems. Utility Model Content

However, under normal conditions, the space in the stomach is small, and after the blood clots are absorbed by the suction tube, the air in the stomach is reduced, making it more difficult to observe the stomach, and it is not convenient to eliminate the blood clots.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1 - Figure 3 The circulating blood clot aspiration system includes a constant-pressure insufflator 1, a gastroscope assembly 2 is installed on the side of the constant-pressure insufflator 1, a mounting block 11 is fixedly installed on the side wall of the constant-pressure insufflator 1, the gastroscope assembly 2 includes an outlet pipe 22 fixedly installed on the mounting block 11, an air suction pipe 24 is fixedly installed on the side of the mounting block 11, one end of the air suction pipe 24 is fixedly connected to a receiving barrel 25, a connecting pipe 23 is fixedly installed on one side of the receiving barrel 25, and an observation unit 21 is fixedly installed between the connecting pipe 23 and the outlet pipe 22.

[0024] When surgical treatment is needed for gastric bleeding in a patient, the device can be used to clean the blood clots in the patient's stomach. First, connect the gastroscope assembly 2 to the constant-pressure pneumoperitoneum machine 1, start the observation unit 21, and with the assistance of the observation unit 21, extend the observation unit 21, the air outlet pipe 22 and the connecting pipe 23 from the patient's mouth into the patient's stomach. At this time, the constant-pressure pneumoperitoneum machine 1 can be started. The constant-pressure pneumoperitoneum machine 1 transmits airflow from the air outlet pipe 22 to the patient's stomach, so that the patient's stomach is expanded, which is convenient for the observation unit 21 to observe the internal environment of the stomach. At this time, the constant-pressure pneumoperitoneum machine 1 simultaneously suctions the stomach through the suction pipe 24, and the blood clots in the stomach are sucked in by the suction pipe 24 through the connecting pipe 23 and accumulate in the receiving bucket 25. The device can clean the blood clots in the patient's stomach through the constant-pressure pneumoperitoneum machine 1, and the constant-pressure pneumoperitoneum machine can keep the patient's stomach in an expanded state, which is convenient for the observation unit to observe the internal environment of the stomach and remove the blood clots.

[0025] Example 2

[0026] See also Figure 2 - Figure 4 A conical air outlet nozzle 221 is fixedly installed at the opening of the air outlet pipe 22, and the tip of the conical air outlet nozzle 221 faces outward. Under the cooperation between the air outlet pipe 22 and the conical air outlet nozzle 221, the air outlet of the conical air outlet nozzle 221 is smaller than the air outlet pipe 22, and the air flow blown out is more concentrated.

[0027] An air suction nozzle 231 is fixedly installed at the open end of the connecting tube 23. The air suction nozzle 231 has a large outer diameter and a small inner diameter. The inner surface of the air suction nozzle 231 is flush with the outer surface of the air suction nozzle 231. With the cooperation between the connecting tube 23 and the air suction nozzle 231, the sucked blood clots are prevented from flowing out again.

[0028] The side of the constant pressure insufflator 1 is rotatably connected to a rotating rod 12, on which a fan blade 13 is fixedly mounted, and the fan blade 13 is mounted inside the suction pipe 24. With the cooperation between the rotating rod 12, the fan blade 13 and the suction pipe 24, when the suction pipe 24 inhales air, the fan blade 13 and the rotating rod 12 are driven to rotate.

[0029] The rotating rod 12 extends into the connecting tube 23, and cutting blades 14 are fixedly installed at equal intervals on the rotating rod 12 in the connecting tube 23. With the cooperation between the rotating rod 12, the connecting tube 23 and the cutting blades 14, the cutting blades 14 on the rotating rod 12 will rotate together with the rotating rod 12 during inhalation to cut the inhaled blood clots.

[0030] The connecting tube 23 is connected with the suction tube 24 and the receiving barrel 25. The connecting tube 23 and the parts of the suction tube 24 located in the receiving barrel 25 have downward bending parts. A filter screen 241 is fixedly installed at the open end of the suction tube 24. With the cooperation between the connecting tube 23, the suction tube 24, the receiving barrel 25 and the filter screen 241, the filter screen 241 can prevent blood clots from being sucked into the constant pressure insufflator 1 when the suction tube 24 inhales.

[0031] When surgical treatment is needed for gastric bleeding in a patient, the device can be used to clean the blood clots in the patient's stomach first, and the observation unit 21, the air outlet tube 22 and the connecting tube 23 are inserted into the patient's stomach from the patient's mouth through the observation unit 21, and the constant-pressure insufflator 1 is started. At this time, the constant-pressure insufflator 1 inputs gas to the stomach through the air outlet tube 22, and the gas is ejected outward from the air outlet tube 22 through the conical air outlet nozzle 221. The outflowing airflow is more concentrated, and the blood clots can be blown through the conical air outlet nozzle 221 to facilitate the suction of the suction nozzle 231. When the air outlet tube 22 supplies air to the stomach, the suction tube 24 simultaneously inhales air into the constant-pressure insufflator 1 to achieve gas pressure maintenance in the stomach. The blood clot is sucked into the connecting tube 23 by the suction nozzle 231, and is cut into small pieces by the rotating cutting blade 14 when moving in the connecting tube 23. The pieces continue to be sucked inward until they fall into the receiving bucket 25, thereby completing the cleaning of the blood clot. The device can break up larger blood clots when sucking in the blood clots, and collect them in the receiving bucket 25 for collection, thereby preventing the blood clots from blocking the pipeline and being sucked into the constant pressure insufflator 1. The device has a simple structure and good practicality.
