Description

Technical Field

[0001] This utility model belongs to the field of enteral nutrition technology, and in particular relates to a disposable one-way valve three-way feeding device. Background Technology

[0002] Currently, in enteral nutrition, tube feeding involves inserting a catheter into the gastrointestinal tract to provide patients with essential food, nutritional solutions, water, and medications. It is one of the most important methods of providing or supplementing nutrition in clinical practice. Tubes are categorized into nasogastric tubes, orogastric tubes, nasoenteric tubes, gastrostomy tubes, and jejunostomy tubes.

[0003] Currently, existing 50 ml feeding tubes have a conical interface that is narrow at the outlet and wide at the inlet, connected to a flared connector similar to a gastric tube. When administering enteral nutrition via tube feeding (taking 200 ml of feeding solution via nasogastric tube as an example), the feeding tube is connected to the end of the gastric tube and aspirated to confirm the tube's position and patency. The end of the tube is then folded back to prevent air from being introduced and causing abdominal distension. After adding a small amount of warm water using the 50 ml feeding tube, the prepared feeding solution is aspirated, and after expiring the air, the tube is connected to the end of the gastric tube and the feeding solution is slowly injected. To inject 200 ml of feeding solution using the 50 ml feeding tube, the tip of the feeding tube needs to be repeatedly dipped into the nasogastric tube to aspirate, expirate the air, and fold back the end of the tube at least four times. This process presents the following problems:

[0004] 1. Frequently inserting the tip of the feeding device into the nasal feeding solution to aspirate increases the risk of contamination and infection.

[0005] 2. After each aspiration, the end of the gastric tube needs to be folded back to prevent air from entering, which is cumbersome and can easily cause abdominal distension in patients.

[0006] 3. Repeated gas expulsion and retraction of the gastric tube increase the workload of nursing staff and reduce efficiency. Utility Model Content

[0007] This utility model addresses the shortcomings of existing technologies by providing a disposable one-way valve three-way feeding device.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a disposable one-way valve three-way feeding device, comprising a feeding connection pipe, a feeding one-way valve three-way device, and a feeding device. One end of the feeding connection pipe is provided with a stepped variable diameter interface, and the other end of the feeding connection pipe is provided with a first threaded interface. The feeding one-way valve three-way device adopts a three-way structure, with its first end connected to the first threaded interface through a first hollow plug-in post, its second end connected to a feeding tube integrally formed therewith, the feeding tube being provided with a counterweight, and its third end being provided with a second threaded interface. The upper end of the feeding device is provided with a second hollow plug-in post, which is connected to the second threaded interface.

[0009] Furthermore, a first fixing nut is sleeved on the first hollow plug-in post, the first hollow plug-in post is inserted into the first threaded interface, and the first fixing nut is screwed onto the outside of the first threaded interface; a second fixing nut is sleeved on the second hollow plug-in post, the second hollow plug-in post is inserted into the second threaded interface, and the second fixing nut is screwed onto the outside of the second threaded interface.

[0010] Furthermore, a first rubber gasket is sleeved on the first hollow plug-in post and located inside the first fixing nut. After the first fixing nut is tightened, the first rubber gasket seals the first threaded interface. A second rubber gasket is sleeved on the second hollow plug-in post and located inside the second fixing nut. After the second fixing nut is tightened, the second rubber gasket seals the second threaded interface.

[0011] Furthermore, the feeding device includes a transparent cylinder with volume markings, a piston that slides with the cylinder, and a push rod disposed on the piston.

[0012] Furthermore, the feeding connection tube and the first threaded interface are integrally formed.

[0013] Furthermore, the feeding connection pipe is equipped with a flow control clamp.

[0014] Furthermore, the feeding one-way valve three-way device is equipped with a one-way valve, which only allows the food chyme to flow unidirectionally from the feeding tube to the feeding connection tube.

[0015] Furthermore, the stepped variable diameter interface is adapted to various clinical feeding tubes, including nasogastric tubes, orogastric tubes, nasoenteric tubes, gastrostomy tubes, and jejunostomy tubes.

[0016] Furthermore, the counterweight is fixed to the free end of the feeding tube, and its density and volume are configured to allow the feeding tube to be stably immersed in the tube feeding liquid without floating.

[0017] Furthermore, the connection between the feeding one-way valve three-way device, the feeding connection pipe, and the feeding device adopts a sterile sealed threaded connection method.

[0018] Compared with the prior art, this utility model has the following advantages.

[0019] This invention allows for a single nasogastric feeding of 200 ml each time, after which the vent is expelled. The feeding tube is placed into the feeding solution until the feeding is complete. The feeding solution is then aspirated by pulling the feeding nozzle and injected into the feeding tube. This eliminates the need for frequent aspiration of the feeding nozzle tip, reducing the risk of infection. Furthermore, each 200 ml feeding only requires one vent, eliminating the need for multiple venting and refraction of the feeding tube tip, thus improving efficiency and preventing the ingestion of air and abdominal distension.
