Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the following description is combined with the detailed description and the accompanying drawings to further explain the preferred embodiments of the present invention.
Examples
Referring to fig. 1-3, the utility model provides an anti-clogging nasogastric tube, which comprises an injection head 1, an outer tube 2, and a lower joint 3, wherein the injection head 1 is connected with one end of the outer tube 2, and the lower joint 3 is connected with the other end of the outer tube 2; the injection head 1 is internally provided with an upper sleeve a and a lower sleeve b, the upper sleeve a is in threaded connection with the lower sleeve b, an inner tube c is arranged in the upper sleeve a, the inner tube c is clamped in the upper sleeve a, and the lower sleeve b is connected with the outer tube 2; a sealing sleeve d1 and a guide hole d2 are arranged in the lower joint 3, the sealing sleeve d1 surrounds the side edge of the lower joint 3, and the guide hole d2 is arranged in the middle of the bottom of the lower joint 3; a fixture block c1 and a filter sheet c2 are arranged in the inner tube c, the fixture block c1 is arranged at the upper end of the inner tube c, and the filter sheet c2 is arranged at the bottom of the inner tube c.
