Pediatric gastric lavage apparatus convenient to slightly adjust

Abstract

The invention discloses a gastric lavage device for pediatrics which is easy to fine-tune, which comprises a handle bar, a gastric lavage tube and a cleaning solution box. The gastric lavage tube is uniformly provided with a number of concave holes, and cleaning holes are arranged in the concave holes. A dirt storage chamber and a control chamber are provided. The dirt storage chamber is connected to the gastric lavage tube through the first communication hole. A piston is arranged in the dirt storage chamber. One end of the piston is fixedly connected to a spring, and the other end of the spring is fixedly connected to the bottom of the dirt storage chamber. On the side wall, the other end of the piston is fixedly connected to the fixed pulley. There is a wire roller in the control chamber. wall and is fixedly connected to the turntable; the setting of the concave hole of the present invention makes the cleaning hole not directly contact with the wall of the gastric cavity, thereby effectively preventing the cleaning hole from being blocked; the spring can increase the resistance of the piston to move to the right, effectively preventing the piston from being online Under the action of the rope, it suddenly moves to the right, causing excessive negative pressure and secondary injury.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pediatric gastric lavage device which is convenient for fine-tuning. Background technique [0002] Gastric lavage refers to pouring a certain composition of liquid into the gastric cavity, mixing the contents of the stomach and then drawing it out, and repeating this many times. Its purpose is to remove unabsorbed poison in the stomach or clean the gastric cavity, and it is clinically used for gastric surgery and preparation before examination. For acute poisoning, such as swallowing organic phosphorus, inorganic phosphorus, alkaloids, barbiturates, etc. within a short period of time, gastric lavage is an important rescue measure. [0003] Gastric lavage is divided into emetic gastric lavage and gastric tube gastric lavage. Emetic gastric lavage, vomiting is the human body's instinctive self-defense response to eliminate toxins in the stomach. Because vomiting-inducing gas...

Problems solved by technology

[0004] The traditional gastric lavage device is simple in structure and easy to operate, but it is poor in fine control of negative pressure control, which is easy to cause harm to patients, especially when extracting gastric lavage fluid and other dirt from children, it is often used due to too fast operation. The suction force of the negative pressure is too large to cause secondary damage to the child, which is not conducive to the normal development of gastric lavage work; the traditional gastric lavage device cannot heat the cleaning liquid, resulting in a large difference between the temperature of the cleaning liquid and the body temperature Especially in winter, the difference between the temperature of the lotion and the body temperature is more obvious. The cleaning process brings a lot of discomfort to the patient, which is not conducive to the treatment of the patient's condition. In severe cases, it may even cause the patient's discomfort and induce other diseases. happen, very dangerous
