Embodiment 1

[0019] See Figure 1: a double-lumen gastric tube, including a tube body, the tube body is provided with a scale 8 marking the insertion depth, and the lumen of the tube body is divided into a main lumen 1 and an auxiliary lumen 2 by a diaphragm , the main lumen 1 and the auxiliary lumen 2 communicate at the head to form a common lumen 3, and side holes 4 are opened on the side wall of the common lumen 3, and the side holes 4 are arranged symmetrically. The lumen 1 and the auxiliary lumen 2 diverge at the tail, and the tail opening of the auxiliary lumen 2 is equipped with a first stopper 5 .

[0020] When in use, when the main lumen 1 is connected to the continuous negative pressure suction system, the first stopper 5 can be opened for forced suction; It is no longer connected to the atmosphere and is in a closed air cavity, so it can maintain negative pressure and can be sucked with a negative pressure ball. It can be seen that it is very convenient to switch between continu...

Embodiment 2

[0026] See Figure 2: The difference between Embodiment 2 and Embodiment 1 is that a metal guide wire 6 is inserted into the main lumen 1. Inserting the metal guide wire 6 can strengthen the hardness of the gastric tube, which is convenient for patients who are under anesthesia or cannot cooperate. use below. When the patient can cooperate in an awake state, only the metal guide wire 6 needs to be drawn out for use.

[0027] Other structures and implementations of the second embodiment are exactly the same as those of the first embodiment.

Embodiment 3

[0029] See Figure 3: The difference between Embodiment 3 and Embodiment 1 is that the tail opening of the main lumen 1 is also equipped with a second plug 7, and when the main lumen 1 is blocked, it can also be sucked from the auxiliary lumen 2 At this time, if a negative pressure ball is used for suction, the second plug 7 that matches the opening at the end of the main lumen 1 needs to be plugged.

[0030] Other structures and implementations of the third embodiment are exactly the same as those of the first embodiment.

Abstract

The present invention relates to a dual-cavity gastric tube including tube body, said tube body has scale for marking insert deepness, said tube body innner cavity is separated into main tube cavity and assistant tube cavity by dissepiment, the main tube cavity and assistant tube cavity are through on head and forms common tube cavity. Said common tube cavity has side hole on side wall, said main tube cavity and assistant tube cavity are forked on tail body, said assistant tube cavity tail body has first plug. The beneficial effects of the dual-cavity gastric tube are: (1) the continuous absorbing system and negative pressure ball absorbing system can be switched conveniently; (2) when the main tube cavity is blocked, the assistant tube cavity can flush directly, if the flush effect is poor, the assistant tube cavity processes absorbing connected with negative pressure system; so the unblocked character between the main tube cavity and stomach is better.

Description

(1) Technical field [0001] The invention relates to a gastric tube. (2) Technical background [0002] Gastric tube is a commonly used clinical device, widely used in gastrointestinal decompression and gastrointestinal nutrition. At present, most of the gastric tubes used clinically are single-lumen gastric tubes. The disadvantages are: the single-lumen gastric tubes are easy to absorb the gastric wall during drainage, causing blockage, or being blocked by gastric contents. Moreover, the suction device needs to be removed for flushing. It is very inconvenient to operate. [0003] Double-cavity stomach tubes have also appeared in the prior art, such as a double-cavity gastric lavage tube disclosed in Chinese patent 01236249.2, which adopts an inner and outer tube structure, and a liquid discharge pipe is set in the liquid inlet pipe, and the liquid inlet pipe and the liquid discharge pipe are in the same position. The entrance is bifurcated, there is a liquid outlet hole on ...
