Description

Feeding guide device TECHNICAL FIELD

[0001] The present invention relates to the technical field of feeding guide devices, and in particular, to a feeding guide device capable of preventing reverse flow of liquid food during feeding. BACKGROUND

[0002] To cope with dysphagia and ensure sufficient nutrition for patients, a nasogastric tube, a nasogastric-jejunal tube or a gastrostomy tube is generally considered to be installed.

[0003] In terms of feeding, a feeding guide device is mainly used to feed in two ways, i.e. the squeezing method and the gravity method. The squeezing method is prone to cause extreme discomfort for patients due to uneven force application or time pressure. Therefore, to improve the discomfort caused by the squeezing method, the gravity method is usually used for feeding.

[0004] The gravity method usually uses a feeding cylinder or a feeding bag (barrel) to load liquid food, and connects the feeding cylinder or the feeding bag (barrel) with a nasogastric tube through a guide tube body, so as to feed the liquid food in the feeding cylinder or the feeding bag (barrel) through the guide tube body and the nasogastric tube. TECHNICAL PROBLEM

[0005] During feeding by the gravity method, a caregiver usually needs to hold the feeding cylinder or the feeding bag (barrel) and pay attention to whether the liquid food has reverse flow. If reverse flow occurs, bacteria or other contaminants in the food may enter the pipeline, increasing the risk of infection.

[0006] Furthermore, after feeding is completed, the caregiver must remove the guide tube body from the nasogastric tube. If the guide tube body cannot be removed in real time, air in the feeding cylinder or the feeding bag (barrel) may enter the patient's body through the pipeline of the guide tube body, causing the patient to have abdominal distension. TECHNICAL SOLUTION

[0007] To solve the above problems, the present invention provides a feeding guide device capable of preventing excess air from entering the patient's body, reducing the possibility of patient distension, and preventing reverse flow of liquid food, thereby effectively ensuring the safety of food and reducing the risk of reverse flow.

[0076] When the continuously flowing liquid food F is transported to the check valve 60 through the guide pipe body 30, the liquid food F will enter the passage 66 from the first port 661 of the passage 66 of the seat body 61, and the valve piece 62 can be affected by the liquid food F, and can be pivoted in a single direction from the closed position to the open position, like the principle of a lever, so that the liquid food F can flow through the passage 66 towards the second end 32 of the guide pipe body 30.

[0077] Please refer to FIG. 4, in the first embodiment of the present application, the weight of the liquid food F is greater than the weight of the reset member 63, so that the valve piece 62 can be pivoted in a single direction with the pivot shaft 65 as the pivoting center, so that the second port 662 of the passage 66 is in communication with the guide pipe body 30; wherein when the liquid food F is not continuously provided, and the liquid food F is partially left in the passage 66 of the check valve 60, because the weight of the residual liquid food F cannot be greater than the weight of the reset member 63, therefore the reset member 63 drives the valve piece 62 to pivot back to the closed position from the open position by the way of the principle of a lever, and the residual liquid food F will be blocked in the passage 66, this effect can fill the gap between the valve piece 62 and the guide pipe body 30, so as to completely block the air from entering the patient's body, and reduce the possibility of bloating.

[0078] Please refer to FIG. 7, in the second embodiment of the present application, the weight of the liquid food F is greater than the elastic torsion of the reset member 63, so that the valve piece 62 can be pivoted in a single direction with the pivot shaft 65 as the pivoting center, so that the second port 662 of the passage 66 is in communication with the guide pipe body 30; wherein when the liquid food F is not continuously provided, and the liquid food F is partially left in the passage 66 of the check valve 60, because the weight of the residual liquid food F cannot be greater than the elastic torsion of the reset member 63, therefore the reset member 63 drives the valve piece 62 to pivot back to the closed position from the open position by the way of the principle of a lever, and the residual liquid food F will be blocked in the passage 66, this effect can fill the gap between the valve piece 62 and the guide pipe body 30, so as to completely block the air from entering the patient's body, and reduce the possibility of bloating.

[0079] A feeding port connector 70 is sleeved at one end of the adapter 50, and the other end of the feeding port connector 70 is connected with an extracorporeal tube 80, one end of the extracorporeal tube 80 is provided with a luer connector 81, the extracorporeal tube 80 can be connected with an intracorporeal tube (not shown in the figure) through the luer connector 81, the intracorporeal tube can be placed in the body of a patient, and the liquid food F is transported to the feeding port connector 70 through the guide tube body 30, enters the extracorporeal tube 80, and is then transported to the body of the patient through the intracorporeal tube, so that the effect of feeding is achieved.

[0080] In summary, the present application can achieve the following effects:

[0081] 1. The present application uses the check valve 60 arranged in the guide tube body 30, which can effectively ensure that only the liquid food F can open the valve plate 62 of the check valve 60, and can prevent excess air from entering the patient's body and reduce the possibility of bloating.

[0082] 2. The valve plate 62 of the check valve 60 can only be opened in one direction, which can prevent the problem of backflow of the liquid food F, thereby effectively ensuring the safety of the food and reducing the risk of backflow.

[0083] 3. The seat body 61 of the check valve 60 can be gradually reduced in diameter through the channel 66, and the buffering effect of the cutting surface 613 can effectively prevent the liquid food F from passing through the valve plate 62 in large quantities, so as to avoid the flow rate of the liquid food F being too fast, which can cause the patient to be injured by choking.

[0084] The above examples are only used to illustrate the present application and are not used to limit the protection scope of the present application.
