Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1 to 2, the embodiment provides a device for spraying powder for endoscopic therapy, comprising an injector 1 and a spraying hose 2, wherein the injector 1 comprises an injection tube 101, a piston 102 and a push rod 103, the piston 102 is arranged in the injection tube 101, the push rod 103 is connected with the piston 102, an hourglass 3 for storing medicine is further arranged in the injection tube 101, the neck of the hourglass 3 is provided with an adjusting valve 5, the opening size of the neck can be controlled by rotating the adjusting valve 5, one end of the hourglass 3 is open, the other end of the hourglass is closed, the end surface of the piston 102 opposite to one side of the push rod 103 is provided with an inner hole with a T-shaped longitudinal section, one closed end of the hourglass 3 is integrally formed with a T-shaped head 4, the T-shaped head 4 is arranged in the inner hole in a matching manner, the piston 102 is made of rubber material and has certain plasticity, so that the hourglass 3 realizes the detachable connection of the piston 102 through the matching of the inner hole and the T-shaped head 4, in order to conveniently load the medicine powder into the hourglass 3, the injection cylinder 101 comprises a cylinder body 1011 and an end head 1012, the end head 1012 is in threaded connection with the front end of the cylinder body 1011, the front end of the end head 1012 is provided with an outlet end, the spraying hose 2 is connected to the outlet end, the end head 1012 and the cylinder body 1011 are connected in a threaded connection mode, so that when the medicine powder is required to be added into the hourglass 3, the end head 1012 only needs to be suspended from the cylinder body 1011, then the medicine powder is added from one end of an opening of the hourglass 3, the medicine powder falls into one closed side, and after the medicine powder is added, the end head 1012 is screwed on.
From the above, in the device for spraying powder for endoscopic therapy provided by this embodiment, when in use, the end head 1012 is taken down from the barrel 1011, the hourglass 3 is pushed out of the barrel 1011 by the push rod 103, the powder is added into the hourglass 3 from the open end, the hourglass 3 is turned over, the neck opening of the hourglass 3 is adjusted to the maximum by adjusting the adjusting valve 5, so that the powder falls into the sealed end of the hourglass 3 quickly, the neck opening of the hourglass 3 is reduced by adjusting the adjusting valve 5, the hourglass 3 is pulled into the barrel 1011 by the push rod 103, the end head 1012 is screwed on the barrel, the spraying hose 2 is connected to the outlet end of the end head, the spraying pipe enters the affected part through the endoscopic forceps channel, the powder is slowly dropped into the injection tube 101 by the hourglass 3, the push rod 103 sprays the powder onto the affected part through the spraying hose 2, thereby preventing a large amount of powder from accumulating in the injection tube 101, causing a blockage to the syringe 101.
In addition, the general spray hose 2 is a hose having an equal diameter, and it is needless to say that the inner diameter of the spray hose 2 may be gradually reduced from one end of the syringe 101 to the end of the spray hose 2 in order to prevent the powder from being coated on the affected part in a large lump when the powder is sprayed, thereby ensuring the spraying effect.
