Embodiment

[0031] The specific embodiment of the present invention is as figure 1 and figure 2 As shown, a multi-purpose spraying conduit includes an inner tube 1, and the two ends of the inner tube 1 are respectively connected with a nozzle 2 and a first liquid injection port 4, and the nozzle 2 is provided with a first spray hole 21; The shell 5 arranged outside the inner tube 1 and in a gap with it, the end of the shell 5 close to the spray head 2 is provided with a ring-shaped second spray hole 7, and the side wall of the other end of the shell 5 is provided with a second liquid injection port 6 The first liquid injection port 4 is located outside the housing 5, and the gap between the outer wall of the spray head 2 and the inner wall of the housing 5 is arranged to form the annular second spray hole 7, and the gap width of the second spray hole 7 is larger than that of the first spray hole. The diameter of the hole 21. The distance between the outer wall of the inner tube 1 and t...

Abstract

The invention discloses a multi-role spraying pipe. The pipe comprises an inner pipe, two ends of the inner pipe are respectively connected with a spraying head and a first injection mouth, and the spraying head is provided with first spraying orifices; the spraying pipe further comprises a shell arranged at the outer side of the inner pipe, gap is reserved between the inner pipe and the shell, and one end of the shell, near the spraying head is provided with second spraying orifices in an annular form; the side wall of the other end of the shell is provided with a second injection mouth, thefirst injection mouth is located at the outer side of the shell, gap is reversed between the outer side wall of the spraying head and the inner side wall of the shell, second spraying orifices in theannular form are formed in the gap, and a gap width between two second spraying orifices is greater than the orifice diameter of each first spraying orifice. According to the multi-role spraying pipe,not only can the liquid medicine with dilute concentration be sprayed, but also the emulsion with high viscosity can be sprayed, and the blocking can not happen.

Description

technical field [0001] The invention relates to the field of medical spraying conduits, in particular to a multipurpose spraying conduit. Background technique [0002] The spraying catheter used at the present stage is the Olympus spraying catheter. The main function of the spraying catheter is dyeing, local spraying of drugs or local flushing. The clinical esophagus is often stained with iodine by the spraying catheter, and the local lesions of gastric disease are treated with methylene Indigo or indigo carmine dyeing, or local spraying of mucosal protective agents such as Javier, or local mucus that affects observation needs to be flushed with normal saline for cleaning. [0003] However, in the original Olympus spraying catheter, the diameter of the outer plastic catheter is 2 mm, and the liquid medicine can only come out from the metal hole with a diameter of 0.5 mm. When the liquid is higher, it will be difficult to spray. When it is necessary to spray a liquid with a...
