Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, in particular to a gastric lavage tube component and a negative pressure gastric lavage device. Background Art

[0002] Gastric lavage is an important measure to rescue patients with food poisoning. The cleaning time and cleaning effect of the stomach are very important for whether the poisoned patients can be successfully rescued. In the process of gastric lavage, a gastric lavage tube is usually used. The current gastric lavage tube is a rubber hose with two openings. When used, one end of the gastric lavage tube is inserted into the patient's stomach, and a cleaning agent is injected into the stomach. When a certain amount is injected, it is discharged from the other end. Its shortcomings are: the entry of the cleaning agent and the exit of food are both through the same pipeline, which is easy to block the tube. If the tube is blocked, it needs to be pulled out and cleaned before being inserted again. Repeated intubation makes the patient very painful and is more likely to damage the digestive tract mucosa and the stomach. In view of this technical problem, it is urgent to have a gastric lavage tube with simple structure, easy to use, and different pipelines for the entry of the cleaning agent and the exit of the food to avoid blocking the tube and avoiding repeated intubation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] A gastric lavage tube assembly, such as Figure 1-Figure 8 As shown, including:

[0035] A gastric lavage tube body 1, one end of which is fixedly connected to a connector 2, a side end of which is provided with a first interface 3 and a second interface 4; the first interface 3 and the second interface 4 have the same caliber;

[0037] A liquid outlet pipe 7 , one end of which is provided with a second clamping joint 8 adapted to the second interface 4 , and the liquid outlet pipe 7 is detachably connected to the connector 2 .

[0038] The gastric lavage tube body 1 in the device is directly used to be inserted into the patient's stomach, and then the liquid inlet tube 5 is connected to the first interface 3 on the connector 2. The end of the liquid inlet tube 5 away from the connector 2 is used to connect with the cleaning device. The cleaning agent is transported to the gastric lavage tube body 1 through the liquid inlet tube 5 through the cleaning device, and then flows into the patient's stomach through the gastric lavage tube body 1 to clean the patient's stomach. The liquid outlet tube 7 is connected to the second interface 4 on the connector 2. One end of the liquid outlet tube 7 is used to connect with the liquid suction and drainage device. The waste liquid in the patient's stomach and the cleaning agent used to clean the stomach are sucked out through the liquid suction and drainage device. The device can achieve cleaning first and then suction, and cleaning and suction can be performed alternately. There is no need to pull out the gastric lavage tube during cleaning and suction, thereby effectively avoiding repeated intubation.

[0039] As a preferred embodiment of the present invention, Figure 1 As shown, a plurality of slots 9 are provided at the side end of the gastric lavage tube body 1 away from the connector 2; the plurality of slots 9 are provided at the end of the gastric lavage tube body 1 away from the connector 2 mainly to facilitate rapid suction of waste liquid in the stomach through the slots 9 and the opening on the gastric lavage tube body 1 during suction.

[0040] As a preferred embodiment of the present invention, Figure 2 , Figure 3 As shown, the first interface 3 and the second interface 4 of the connector 2 are both provided with sealing plugs 10 matched with the first interface 3 and the second interface 4 .

[0041] As a preferred embodiment of the present invention, Figure 1 , Figure 8 As shown, a locking assembly 11 is installed at one end of the liquid inlet tube 5 away from the connector 2; the locking assembly 11 includes a locking outer frame 12 and a locking block 13 adapted to the locking outer frame 12. The locking assembly 11 is mainly used to lock the liquid inlet tube 5 after the cleaning agent is input into the stomach, so as to facilitate the liquid suction device to suck out the waste liquid in the stomach. If the liquid inlet tube 5 is not locked, the liquid inlet tube 5 and the inside of the gastric lavage tube body 1 are connected, which is not conducive to the liquid suction device to suck liquid through the liquid outlet tube 7.

[0042] As a preferred embodiment of the present invention, Figure 6 , Figure 7 As shown, the locking outer frame 12 is in a trapezoidal shape, a through hole 14 is provided at the side end of the locking outer frame 12, a receiving cavity 15 is provided inside the locking outer frame 12, and slide grooves 16 are provided on the inner wall of the locking outer frame 12 on both sides of the receiving cavity 15; the locking block 13 is in a square structure, the locking block 13 is adapted to the receiving cavity 15 inside the locking outer frame 12, a slider 17 adapted to the slide groove 16 is fixedly installed at the side end of the locking block 13, and the locking block 13 can slide freely in the receiving cavity 15 of the locking outer frame 12.

[0043] As a preferred embodiment of the present invention, Figure 7 , Figure 8 As shown, a groove 18 is opened at one end of the inner wall of the locking outer frame 12, and a first magnet block 19 is fixedly installed in the groove 18; a second magnet block 20 is fixedly installed on the side end of the locking block 13, the first magnet block 19 is adapted to the second magnet block 20, and the magnetic properties of the first magnet block 19 and the second magnet block 20 are opposite.

[0044] As a preferred embodiment of the present invention, Figure 8 As shown, when the locking block 13 slides to the groove 18 in the accommodating cavity 15 of the locking outer frame 12, and the second magnet block 20 at the side end of the locking block 13 fits with the first magnet block 19 in the groove 18, the locking block 13 locks the liquid inlet pipe 5, and the upper tube wall and the lower tube wall of the liquid inlet pipe 5 fit together.

[0045] It should be noted that the specific steps and principles of using the locking assembly 11 to lock the liquid inlet pipe 5 are as follows: during the locking process, first slide the locking block 13, and slide the locking block 13 in the accommodating cavity 15 toward the groove 18 inside the locking outer frame 12, and then Figure 6 and Figure 8It can be seen that the slide groove 16 in the locking outer frame 12 is in an inclined state. Therefore, when the locking block 13 slides to the groove 18, the bottom of the locking block 13 will gradually squeeze the liquid inlet pipe 5. When the locking block 13 slides to the groove 18 in the accommodating cavity 15 of the locking outer frame 12, and the second magnet block 20 at the side end of the locking block 13 fits with the first magnet block 19 in the groove 18, the locking block 13 squeezes the liquid inlet pipe 5 so that the upper tube wall and the lower tube wall of the liquid inlet pipe 5 fit together. At this time, the locking block 13 locks the liquid inlet pipe 5.

[0046] As a preferred embodiment of the present invention, Figure 1 As shown, a scale bar 21 is provided at the side end of the gastric lavage tube body 1 for easy observation.

[0047] As a preferred solution of the utility model, the gastric lavage tube body 1, the liquid inlet tube 5 and the liquid outlet tube 7 are all transparent plastic hoses. The gastric lavage tube body 1, the liquid inlet tube 5 and the liquid outlet tube 7 are all transparent plastic hoses mainly to facilitate observation of the internal conditions of the three tube bodies, and when the three tube bodies are blocked by foreign matter, they can be replaced in time.

[0048] A negative pressure gastric lavage device comprises the gastric lavage tube assembly described above.

[0049] The working principle and use process of this utility model:

[0050] When the device is in use, the gastric lavage tube body 1 is directly inserted into the patient's stomach, and then the liquid inlet tube 5 is connected to the first interface 3 on the connector 2. The end of the liquid inlet tube 5 away from the connector 2 is used to connect with the cleaning device. The cleaning agent is transported to the gastric lavage tube body 1 through the liquid inlet tube 5 through the cleaning device, and then flows into the patient's stomach through the gastric lavage tube body 1 to clean the patient's stomach. The liquid outlet tube 7 is connected to the second interface 4 on the connector 2. One end of the liquid outlet tube 7 is used to connect with the liquid suction and drainage device. The waste liquid in the patient's stomach and the cleaning agent used to clean the stomach are sucked out by the liquid suction and drainage device. The device does not need to pull out the gastric lavage tube during the cleaning and suction process, thereby effectively avoiding repeated intubation. During the suction process, the liquid outlet tube 7 needs to be locked by the locking component 11 to facilitate suction. When the cleaning agent needs to be input, the locking state of the locking component 11 on the liquid inlet tube 5 is released.
