Description

Nasogastric tube flow rate valve for feeding bag and method of use thereof

The present invention relates to a medical device, in particular to a nasogastric tube flow rate valve for a feeding bag and a method of using the same.

A feeding bag is a medical device designed specifically to provide nutritional support. It is mainly used for patients who are unable to eat normally, such as critically ill patients, those recovering from surgery, patients with dysphagia, or long-term bedridden patients. The main function of a feeding bag is to deliver liquid food or nutrients directly to the patient's stomach through a tube to ensure that they can get the nutrition they need. This device is usually connected to a nasogastric tube and can adjust the flow rate and formula according to the patient's needs.

A known feeding bag comprises: a bag body, with an inlet at the upper part and an outlet at the lower part, and a bag cavity connected to the inlet and the outlet, wherein liquid food is poured into the bag cavity from the inlet and discharged from the outlet; a guide tube body, having a first end and a second end, wherein the first end is connected and communicated with the outlet of the bag body; a flow rate regulator, disposed between the first end and the second end of the guide tube body, for controlling the flow rate of the liquid food in the guide tube body; a check valve, disposed between the first end and the second end of the guide tube body, for preventing the liquid food from flowing back during the feeding process; and a joint, connected and communicated with the second end of the guide tube body, for being assembled with a nasogastric tube.

However, the flow rate regulator of the known feeding bag does not have a locking function and cannot be easily adjusted to maintain the set flow rate. In addition, during use, the guide tube body and the nasogastric tube need to be disassembled, and a syringe is connected to one end of the nasogastric tube to perform back suction observation to confirm the amount and color of residual food in the patient's stomach, then the push-pull rod of the syringe is pulled out, and an appropriate amount of warm boiled water is poured into the syringe. The warm boiled water is poured into the patient's stomach along the nasogastric tube to moisten the tube wall of the nasogastric tube, and then the guide tube body and the nasogastric tube are reassembled. This series of steps is not only cumbersome, but also easily causes the operator to be in a hurry, increases the risk of air entering the patient's stomach, and may cause contamination problems.

The inventor of the present invention, in view of the above-mentioned shortcomings of known feeding bags, came up with the idea of creating a new invention. After much discussion and trial production of samples, as well as many revisions and improvements, the present invention was launched.
