Abstract

The invention relates to the technical field of medical instruments, and discloses a hemostatic powder ejector. The hemostatic powder ejector comprises an ejector main housing and an ejector sub-housing. A gas cylinder is disposed in the ejector main housing, the bottom of the ejector main housing is provided with an end cap, and an opening of the gas cylinder is provided with an air valve. A gas-powder mixing sleeve is disposed in the ejector sub-housing, a gas-powder mixing cavity is disposed in the gas-powder mixing sleeve, the upper end of the gas-powder mixing sleeve is provided with a medicine bottle, a medicine outlet of the medicine bottle communicates with the gas-powder mixing cavity, the lower end of the gas-powder mixing sleeve comes out of the ejector sub-housing and the lower end is provided with a nozzle. A gas tube is disposed in the connecting housing, one end of the gas tube is connected with the air valve, and the other end of the gas tube communicates with the gas-powder mixing cavity. The hemostatic powder ejector is convenient to operate, the hemostatic powder can be accurately transported to a focus and uniformly spayed on the focus to stop bleeding.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemostatic powder injector. Background technique [0002] At present, for gastrointestinal bleeding caused by diseases or operations, the commonly used methods include injection of epinephrine and sclerosing agents. The injection therapy is simple to operate and has quick results, but the rebleeding rate is high; non-contact thermal coagulation therapy such as argon ion coagulation, contact Type thermocoagulation therapy such as thermal probe, bipolar electrocoagulation, thermocoagulation therapy uses heat source to burn the bleeding part to stop bleeding, which is easy to cause tissue damage, and the electrocoagulation head is easy to adhere to the tissue during contact thermocoagulation, and it is easy to cause rebleeding when it leaves the tissue; Mechanical therapy, such as ligation, titanium clips, and OTSC, is the most accurate method for treating gastrointest...
