detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc. used in the present application indicate orientation or positional relationship based on the drawings The orientation or positional relationship shown is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a reference to the present invention. Utility model restrictions. In addition, the terms "first" and "second" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance.

As shown in Figures 1 and 2, the embodiment of the present application proposes a neonatal gastric tube, including: a body 1 and a net bag 2, the first end of the body 1 is open, and the first end of the body 1 is used to connect a syringe Or a negative pressure suction device, the second end of the body 1 is closed, and the body 1 is provided with at least eight holes 3 near the second end of the body 1, and the holes 3 are along the tube wall of the body 1 The front and back are arranged at intervals, the net pocket 2 is covered on the second end of the body 1, and the net pocket 2 is covered on all the holes 3, and the net pocket 2 is provided with grids 4 arranged at intervals. The aperture of the grid 4 is smaller than the aperture of the hole 3 .

Based on the above technical solution, the milk required by the newborn is injected through the opening of the first end of the main body 1 or the stomach contents are sucked out, and at least eight holes 3 are arranged at the second end of the main body 1, which greatly increases the milk injection speed and pumping. The efficiency when sucking the contents of the stomach, and the net bag 2 with the grid 4 is set on the hole 3, so that the local pressure can be relieved when the gastric tube is sucked under negative pressure without causing milk blockage Protect the gastric mucosa of newborns, drain the liquid and gas in the stomach better and faster, and reduce the occurrence of gastrointestinal bleeding.

In some embodiments of the present application, as shown in FIG. 1 , the number of holes 3 is 8-10. The number of holes 3 is preferably 8.
