Description

Technical Field

[0001] The utility model relates to the technical fields of medical instruments and the like, and in particular to a manual gastric lavage device. Background Art

[0002] Gastric lavage is the most direct and first-choice measure to prevent further absorption of poisons and save lives. It is also the most commonly used and effective method in clinical practice. Gastric lavage is most effective within 4-6 hours after poisoning. Gastric lavage is usually performed using a gastric tube. A gastric tube is inserted into the patient's stomach, and a certain amount of solution is repeatedly injected and aspirated to flush and remove gastric contents, reducing or avoiding absorption of poisoning. Gastric lavage is a method of clearing poisons or irritants from the stomach and reducing poison absorption. Different lavage solutions can also be used for neutralization and detoxification, and are used for acute food or drug poisoning. However, in grassroots community hospitals that do not yet have gastric lavage machine facilities or when a large number of food poisoning patients require emergency gastric lavage and the gastric lavage machine cannot meet the needs, the lives of poisoned patients will be threatened.

[0003] Therefore, domestic clinical personnel need to consider introducing and independently developing a manual simple gastric lavage device, which is extremely important for grassroots community hospitals that do not have gastric lavage facilities or when a large number of food poisoning patients require emergency gastric lavage and the gastric lavage machine cannot meet the needs, and promote it for clinical use.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific implementations, but they are not intended to limit the present invention.

[0021] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose of the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0022] like Figures 1 to 3 As shown, a manual gastric lavage device of a preferred embodiment is shown, which includes: a water inlet 1, a hard tube 2, a first hose 3, an extrusion air bag 4, a second hose 5, a Y-shaped tube 6, and a first regulating valve 7.

[0023] The water inlet 1, the hard tube 2, the first hose 3, the extrusion airbag 4, and the second hose 5 are connected in sequence; the Y-shaped tube 6 is provided with a connecting port 8, a negative pressure interface 9 and a gastric tube interface 10; the first regulating valve 7 is installed at the connecting port 8; the second hose 5 is installed at the first regulating valve 7.

[0024] In actual use, put the water inlet 1 into the clean water bucket 13, open the first regulating valve, close the negative pressure interface 9, and manually squeeze the airbag 4 continuously. Due to the atmospheric pressure and siphon phenomenon, the solution in the clean water bucket 13 flows along the Figure 2 In the direction indicated by the arrow, the first hose 3, the extrusion airbag 4, the second hose 5 enter the Y-shaped tube 6, and finally enter the patient's stomach. Then the negative pressure interface of the Y-shaped tube 6 is connected to the suction bottle 14, and the second regulating valve 12 is opened. The patient's stomach solution flows along the negative pressure. Figure 3 The liquid is continuously sucked into the suction bottle 14 in the direction of the arrow.
