[0026] Embodiment 1
[0027] Reference Figure 1The embodiment provides a stomach tube pressure reducer, which comprises a stomach tube pressure reducer body, wherein the stomach tube pressure reducer body comprises a negative pressure bottle 1, a connecting pipe 2 for connecting a stomach tube arranged on the negative pressure bottle 1, and a pouring opening 3 arranged on the negative pressure bottle 1; a flow stop clamp 6 is arranged on the connecting pipe 2 (in the embodiment, the flow stop clamp 6 is a pressing type, compared with a traditional roller type flow stop clamp, the risk that the roller is knocked open due to negative pressure inertia and cannot be completely stopped when the roller is rolled to a completely closed side is reduced, and the operation is more convenient); and an adjusting piece 4 is arranged on the pouring opening 3, and the adjusting piece 4 can be used for adjusting the opening size of the pouring opening 3. In the embodiment, the pouring opening 3 and the adjusting piece 4 are connected in a rotating clamping mode. The top of the pouring opening 3 is partially open and partially closed, and the bottom of the adjusting piece 4 is partially open and partially closed. In order to enhance the sealing effect, a sealing ring is arranged between the top of the pouring opening 3 and the bottom of the adjusting piece 4. Further, since the negative pressure bottle 1 cannot be stably placed on a plane due to the force generated by deformation of the negative pressure bottle 1 during the process from the compressed state to the original state, at least two connecting pieces 7 (two connecting pieces 7 are symmetrically arranged in the embodiment) are arranged on the negative pressure bottle 1, and the connecting pieces 7 can be used for threading a rope belt, and the rope belt is used for fixing the stomach tube pressure reducer body on different carriers. Further, in order to better observe the color, state and volume of the stomach contents of a patient, the negative pressure bottle 1 is made of transparent or translucent material, and a scale line is arranged on the negative pressure bottle 1, and the unit of the scale line is ml.
[0028] In the embodiment, the opening part and the closing part of the bottom of the adjusting piece 4 each account for half, and the opening part and the closing part of the top of the pouring opening 3 each account for half. When the stomach tube pressure reducer is used, the stomach tube is inserted into the oral cavity or the nasal cavity of a patient, the adjusting piece 4 is rotated to separate the opening part of the bottom of the adjusting piece 4 from the closing part of the top of the pouring opening 3, the negative pressure bottle 1 is squeezed to reach a compressed state, then the adjusting piece 4 is rotated to completely coincide the opening part of the bottom of the adjusting piece 4 with the closing part of the top of the pouring opening 3, so that the negative pressure bottle is sealed and kept in a negative pressure state, then the other end of the stomach tube is connected with the connecting pipe 2 by using an existing connection mode, and then the flow stop clamp 6 on the connecting pipe 2 is opened. When pouring, the situation of the stomach contents in the negative pressure bottle 1 is observed first, the adjusting piece 4 is rotated according to the size of the stomach contents to obtain different opening sizes of the pouring opening 3. Different stomach contents with different sizes can be poured correspondingly, so that the odor emitted during pouring is reduced to the greatest extent (when the opening is too large, the odor emitted is larger, so the opening needs to be matched with the size of the stomach contents, and the diffusion of the odor is reduced as much as possible under the condition of ensuring the discharge).
[0029] Embodiment 2
[0030] Reference Figure 2 、 Figure 3, In order to be more easily poured and reduce the risk of splashing of the stomach contents when pouring, the embodiment is provided with a drainage member for guiding flow on the adjusting member 4, the drainage member is threadedly connected with the adjusting member 4, and the drainage member is a drainage pipe 5, the top of the drainage pipe 5 is beveled. Further, in order to prevent the stomach contents from flowing through the closed part of the adjusting member 4 when pouring, causing the pouring to be not smooth, the top end of the top bevel of the drainage pipe 5 is on the same side as the open part of the bottom of the adjusting member 4. This design makes the flow trajectory of the liquid be constrained, and the liquid is not easy to cause splashing, which is more preferred.
[0031] The above is only a preferred embodiment of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
