Description

Technical Field

[0001] The invention relates to the technical field of gastric lavage apparatus, and in particular to a gastric lavage apparatus for clinical use in children. Background Art

[0002] Nowadays, the safety incidents of infants and young children swallowing by mistake occur frequently. In order to provide emergency treatment for infants and young children who swallow by mistake, the method of gastric lavage is adopted. Gastric lavage is to input the cleaning liquid into the stomach through the gastric lavage device, dilute the irritants inside, and extract them, and repeat the process to achieve the effect of cleaning the stomach. In the actual use process of the current gastric lavage device, it is first necessary to insert the catheter into the patient's stomach, then connect the other end of the catheter to the sampling bottle, take out some gastric juice for detection, then remove the sampling bottle at the other end of the catheter, connect the other end of the catheter to the cleaning bucket, and transport the cleaning liquid inside the cleaning bucket to the patient's stomach, and then connect the catheter to the sewage bucket, and suck out the gastric juice inside the patient's stomach by low pressure, and repeat the process. Gastric lavage in this way requires continuous replacement of the cleaning bucket and the sewage bucket, which not only improves the labor intensity of the staff, but also reduces the efficiency of gastric lavage. On the other hand, in the process of gastric lavage, it is necessary to continuously sample the gastric juice. Since the current sampling method is slow, the overall efficiency of gastric lavage is once again reduced.

[0003] In response to the above problems, the application with publication number: CN219208398U discloses a pediatric clinical gastric lavage device, including a cleaning bucket, a cleaning pipe is fixedly connected to the top of the cleaning bucket, an adjusting component is provided at one end of the cleaning pipe, a sewage pipe is fixedly connected to one side of the adjusting component, a sewage bucket is fixedly connected to one end of the sewage pipe, a connecting pipe is fixedly connected to one end of the adjusting component, a sampling component is provided at one end of the connecting pipe, a sampling bottle is threadedly connected to the bottom end of the sampling component, and a catheter is fixedly connected to one end of the sampling component. In actual use, the device only needs to press and turn the knob to complete the infusion and extraction of the patient's stomach. Compared with the traditional method of infusion and extraction, the device not only reduces the labor burden of the staff, but also improves the gastric lavage efficiency of the patient, thereby greatly improving the practicality of the device.

[0004] However, the following problems still exist during the use of this pediatric clinical gastric lavage device: 1. This pediatric clinical gastric lavage device cannot fix the gastric tube. Children may feel uncomfortable during gastric lavage and may move around, causing the gastric tube to fall off. Re-insertion may cause additional pain and possible injury to the children. 2.
