Injector support

Abstract

The invention discloses an injector support comprising a fixing device and a speed changing device arranged in the fixing device. The fixing device includes a shell internally provided with a communicated cavity and a fixing ring arranged on the surface of the shell. The speed changing device includes two symmetrically-arranged guide rails slidably connected with a first mounting groove and a transmission gear set arranged between the two guide rails; and the transmission gear set includes a first gear, an idle wheel and a second gear. The medical staff can control the injection rate of the large-capacity injector by the speed changing device, so that a phenomenon that small-capacity injectors are replaced many times to inject liquid medicine into a patient is avoided; and thus the pain ofthe patient is relieved and the operation is simplified; and the use cost of the injector is reduced.

Description

technical field [0001] The invention relates to a syringe bracket, which belongs to the technical field of syringes. Background technique [0002] A syringe is a common medical device. As early as the 15th century, the Italian Catinelle proposed the principle of the syringe. Primarily used for the extraction or injection of gases or liquids with needles, syringes can also be used to inject medical equipment, containers, and scientific instruments such as some chromatography through rubber septums. There is a problem when using syringes in clinical medicine. For example, when a patient needs to inject 20ml of liquid medicine, it is necessary to use a syringe of 5ml or even 1ml to extract it from the liquid bottle several times and inject it into the patient. Because of the large volume For a 20ml syringe, if the needle is too thick to pierce the patient directly, the most important thing is that the 20ml syringe is difficult to achieve fine manipulation, and the injection s...

Problems solved by technology

There is a problem when using syringes in clinical medicine. For example, when a patient needs to inject 20ml of liquid medicine, it is necessary to use a syringe of 5ml or even 1ml to extract it from the liquid bottle several times and inject it into the patient. Because of the large volume For a 20ml syringe, if the needle is too thick on the one hand, it cannot directly pierce the patient. The most important thing is that the 20ml syringe is difficult to achieve fine manipulation, and the injection speed is too fast, and the patient cannot bear it.

Therefore, there is a disadvantage that multiple injections not only waste the syringe, but also cause the patient to be stabbed many times, and the experience is very bad.
