Description

Technical Field

[0001] This application relates to the technical field of gastric juice reinfusion, and particularly to a gastric juice reinfusion device. Background Art

[0002] Gastric retention refers to the accumulation of gastric contents that cannot be emptied in a timely manner, usually measured by gastric residual volume. Its incidence during enteral nutrition in critically ill patients is 3% - 58%. It easily leads to the interruption or delay of enteral nutrition in critically ill patients, fails to achieve the due nutritional goals, and affects disease treatment.

[0003] Currently, in clinical practice, when gastric retention occurs during enteral nutrition for critically ill patients, if the GRV is continuously monitored > 350 ml for two consecutive times, gastric retention fluid is reinfused. When GRV ≥ 500 ml, enteral nutrition is immediately suspended, and the gastric retention fluid is discarded without reinfusion.

[0004] When performing gastric juice reinfusion, the existing technical solution is as follows: The gastric juice drawn out with a syringe is placed into a clean container, and then slowly injected through nasogastric feeding. The flocs in the gastric juice are filtered with a gauze before reinfusion. The disadvantages of this method are: ① Manual aspiration and reinfusion are time-consuming. ② The aspirated gastric juice is easily contaminated: exposed to the air, it is prone to bacterial growth. ③ It is easy to block the gastric tube. Utility Model Content

[0005] The present invention provides a gastric juice reinfusion device, which can realize the reinfusion of gastric juice in a closed environment, avoid the exposure of gastric juice to the air, and can filter the flocs in the gastric juice.

[0008] The first stop clamp is arranged on the inlet pipe, and the second stop clamp is arranged on the outlet pipe; one end of the inlet pipe is communicated with a gastric intubation tube, and the other end is communicated with the drainage fluid collection container; one end of the outlet pipe is communicated with the filtering component, and the other end is communicated with the drainage fluid collection container. The outlet end of the filtering component is communicated with the gastric intubation tube.

[0009] Among them, gastric juice is collected by the drainage fluid collection container, and after turning its orientation, it is used for reinfusing gastric juice. Compared with nasogastric reinfusion, the whole process is more convenient to operate, and the gastric juice will not be exposed to the air, avoiding the growth of pathogenic bacteria.

[0010] At the same time, the filtering component filters the flocs in the gastric juice to avoid blocking the pipeline during reinfusion.

[0011] Preferably, the filtering component includes a hollow liquid storage bladder and a filter screen cylinder. The filter screen cylinder is fixedly arranged inside the hollow of the liquid storage bladder, and the upper end opening of the filter screen cylinder is communicated with the liquid outlet pipe.

[0012] Among them, the filter screen cylinder filters the floccules in the gastric juice to prevent the tube for backfeeding gastric juice from being blocked.

[0013] Preferably, the gastric juice backfeeding device further includes a water injection container, and the water injection container is communicated with the liquid outlet pipe through a first connecting pipe.

[0014] Preferably, a third stop clamp is provided on the connecting pipe.

[0015] Preferably, the gastric juice backfeeding device further includes an infusion pump, and the liquid storage bladder is communicated with the infusion pump through a second connecting pipe.

[0016] Preferably, the gastric juice backfeeding device further includes a pipeline heater. The infusion pump and the gastric intubation tube are communicated through a third connecting pipe, and the pipeline heater is installed at the outer end of the third connecting pipe.

[0017] Preferably, a negative pressure aspirator is externally connected to the drainage fluid collection container.

[0018] Compared with the prior art, the advantages or beneficial effects of the technical solution of the present application include:

[0019] 1. It can effectively recover gastric juice and relieve the symptoms of gastric retention in patients.

[0020] 2. The operation is simple, with automatic drainage and backfeeding, saving manpower.

[0021] 3. The whole device is a closed loop, and the gastric juice will not be exposed to the air, reducing the probability of gastric juice being contaminated.

[0022] 4. By setting the filtering component, the gastric juice can be filtered to reduce the probability of the gastric tube being blocked. Description of the Drawings
