Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a gastric lavage device for clinical use. Background Art

[0002] At present, when the emergency internal medicine department rescues patients with food poisoning or drug ingestion, it is often necessary to perform gastric lavage on the patients through a gastric lavage device. During the treatment process, the cleaning liquid is transported into the patient's gastric cavity through the gastric lavage device, mixed and diluted with the reactants in the gastric cavity and then pumped out. For example, a gastric lavage device for clinical use in emergency internal medicine disclosed in the existing patent (application number: CN202121389644.6) is a device for performing gastric lavage on patients.

[0003] However, during the use of the above-mentioned gastric lavage device, since the volume of the liquid storage tank in the device is fixed and non-adjustable, it is impossible to adjust the liquid consumption according to different patients during gastric lavage, which brings inconvenience to the gastric lavage work. At the same time, for the waste liquid after suction, the sundries and gastric juice cannot be effectively separated, so when doctors further detect the pH value, drug concentration or other indicators in the gastric juice to assist in diagnosis and monitor the treatment effect, the sundries in the waste liquid will interfere with the detection results.

[0004] Therefore, we propose a gastric lavage device for clinical use to solve the above problems. Content of the Utility Model

[0029] The operating principle of the present utility model is described as follows:

[0030] When using this device, first, control the electric cylinder 51 to start through an external control switch, so that the electric cylinder 51 controls the liquid volume limiting plate 4 to move downward. The liquid volume limiting plate 4 will drive the scale rod 53 to move downward. When the scale on the scale rod 53 indicated by the pointer 52 reaches the required value, turn off the electric cylinder 51. Then, open the third solenoid valve 21, and inject cleaning liquid into the lower space of the liquid volume limiting plate 4 through the liquid injection hopper 71. The liquid storage tank 3 is made of a transparent material such as acrylic material to facilitate observing the liquid injection situation. When the liquid level of the injected cleaning liquid contacts the bottom surface of the liquid volume limiting plate 4, turn off the electric cylinder 51 and the third solenoid valve 21. Then, place a dental pad in the patient's mouth, and lubricate the front end of the gastric tube 11 with paraffin oil. Subsequently, insert the gastric tube 11 into the mouth through the opening of the dental pad until it is inserted into the stomach. Then, open the first solenoid valve 13, so that the quantitatively stored cleaning liquid in the liquid storage tank 3 passes through the three-way pipe 8, and then through the infusion tube 9 and the gastric tube 11 and is sent to the patient's stomach. During the infusion process, the electric cylinder 51 can be used to control the liquid volume limiting plate 4 to slowly move downward to apply a certain pressure to the cleaning liquid, so that the cleaning liquid can smoothly enter the patient's stomach;

[0031] After the infusion is completed, close the first solenoid valve 13, open the second solenoid valve 14, and start the suction pump 12, so that the suction pump 12 can cooperate with the gastric tube 11 to pump the gastric juice and sundries in the patient's stomach into the sewage discharge tank 17. Under the action of the filter net 19, the waste liquid can be filtered. After the liquid pumping is completed, open the valve on the sewage discharge port 20 on the lower side of the sewage discharge tank 17, and discharge the gastric juice separated by the filter net 19 into a special container for subsequent inspection and targeted treatment. After the liquid discharge is completed, close the valve on the lower sewage discharge port 20, and control the sewage discharge tank 17 to turn over through the stepper motor 18, so that the upper sewage discharge port 20 rotates to the lower side to facilitate the discharge of sundries.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
