Description

Feeding reflux detection device

The present invention relates to a detection device, and more particularly to a feeding reverse flow detection device that can improve the safety of the feeding process.

With the rapid development of science and technology, medical technology is constantly advancing, resulting in significant breakthroughs in the discovery and treatment of many diseases. These advances not only increase the survival rate of patients with injuries but also significantly improve their quality of life. However, for some patients who are unable to feed themselves due to injury, illness, or aging, they still face many challenges. These patients often need to rely on medical staff or caregivers to feed them through a nasogastric tube to ensure they receive adequate calories and nutrients.

Nasogastric tube feeding provides nutritional support and ventilation for patients with difficulty swallowing. It delivers liquid food through the nasal cavity into the stomach, meeting the patient's basic needs. However, this procedure is not without risk. During tube feeding, patients may experience reflux due to vomiting, coughing, or fluid obstruction. This reflux not only causes discomfort to the patient, but if the tube feeding is not stopped promptly, the liquid may enter the airway and cause accidental aspiration, leading to serious complications such as aspiration pneumonia. Therefore, the development of a device that can instantly detect tube feeding reflux is of great significance for improving patient safety and quality of life.

In view of the aforementioned problems, the inventors came up with the idea for this invention. After extensive research, trial production, and numerous revisions and improvements, they finally came up with the present invention.

The present invention relates to a feeding reflux detection device comprising: a feeding bag comprising a bag body and an infusion tube. The bag body has a bag cavity for containing liquid food and an outlet at its bottom that communicates with the bag cavity. One end of the infusion tube is connected to the bag body outlet; and a reflux detection device comprising a first port, a second port, a first channel, a second channel, and a pressure detector. The first port is connected to the other end of the infusion tube. The second port is used to connect to a nasogastric tube. The first channel is disposed between the first and second ports. The lower end of the second channel is connected to the first channel. The pressure detector is mounted at the upper end of the second channel and is used to automatically monitor pressure changes within the first channel.

The primary purpose of this inventive reverse flow detection device is to instantly detect reverse flow during the in-feeding process and automatically sound an alarm, effectively preventing complications such as aspiration and ensuring the safety and effectiveness of in-feeding.

Another purpose of the present invention's reflux detection device is to enable deflation via the pressure detector when not feeding, if deflation is necessary, while also triggering an alarm system to alert caregivers to take appropriate care measures.

The following is a further description of the present invention with reference to the drawings of the preferred embodiments, in the hope that those familiar with the relevant technology of the present invention can implement it according to the description in this manual.

First, please refer to Figures 1 to 5. The feeding reflux detection device of the present invention includes a feeding bag 10 and a reflux detection device 20.

The feeding bag 10 comprises a bag body 11, an infusion tube 12 and a check valve 13. The bag body 11 is provided with a bag cavity 111 for accommodating liquid food. The bag body 11 is provided with an inlet 112 connected to the bag cavity 111 on the top and equipped with a plug 113. The bag body 11 is provided with an outlet 114 connected to the bag cavity 111 on the bottom. The liquid food is injected into the bag cavity 111 through the inlet 112. 11, and is output from the outlet 114. The liquid infusion tube 12 is made of elastic plastic or silicone material. One end of the liquid infusion tube 12 is connected to the outlet 114 of the bag 11. The check valve 13 is installed on the liquid infusion tube 12 to prevent the liquid food from flowing back into the bag 11 during feeding, ensuring the one-way flow of the liquid food. The check valve 13 is a known technology and is not the focus of this case. Its detailed structure will not be described here.

The reverse flow detection device 20 includes a first port 21, a second port 22, a first channel 23, a second channel 24, and a pressure detector 25. The first port 21 is connected to the other end of the infusion tube 12. The second port 22 is connected to the inlet 31 of a nasogastric tube 30. The first channel 23 is located between the first and second ports 21, 22. The lower end of the second channel 24 is connected to the first channel 23. The pressure detector 25 is mounted at the upper end of the second channel 24 to automatically monitor pressure changes within the first channel 23. In this embodiment, the first port 21 is disposed at the upper end of a cylinder 26. The cylinder 26 is comprised of a first component 26A and a second component 26B screwed together. The second port 22 is disposed at the lower end of the cylinder 26. The first channel 23 is disposed within the cylinder 26 and communicates with both the first port 21 and the second port 22. The second channel 24 is also disposed within the cylinder 26 and separated from the first channel 23 by a partition 261. A vent 262 is provided on the cylinder 26 corresponding to the pressure detector 25. The vent 262 communicates with the pressure detector 25. The pressure detector 25 is conventional and not the focus of this invention, so its detailed structure will not be described here.

During the feeding process, as shown in Figure 6, the liquid food in the bag cavity 111 flows by gravity from the bag cavity 111 to the outlet 114, passing through the infusion tube 12, the check valve 13, the backflow detection device 20, and the nasogastric tube 30 into the patient's stomach. Due to the connecting tube principle, the liquid levels in the first channel 23 and the second channel 24 remain consistent.

As shown in Figures 7 and 8, when a patient vomits, coughs, or experiences backflow due to fluid obstruction, the liquid levels in the first and second channels 23 and 24 rise simultaneously, compressing the air in the second channel 24 and causing the air pressure therein to increase. The pressure detector 25 instantly detects this pressure change and transmits a signal to the warning device 40, sounding an alarm. The warning device 40 can be a buzzer and/or a warning light, alerting medical personnel or caregivers to stop the feeding and take necessary measures.

Furthermore, Figures 9 and 10 illustrate another embodiment of the force-feeding reflux detection device of the present invention. This embodiment differs from the aforementioned embodiment in that it further includes a mechanical feeder 50. The mechanical feeder 50 is equipped with a rotor 51 around which the liquid infusion tube 12 is wound. By adjusting the rotation of the rotor 51, the feeding speed of the liquid food can be precisely controlled. When the pressure detector 25 detects a change in pressure, it sends a signal to the mechanical feeder 50, triggering an audible and/or visual alarm and automatically stopping force-feeding.

As shown in FIG11 and FIG12, another embodiment of the feeding backflow detection device of the present invention is shown. The difference between this embodiment and the above embodiment is that the first interface 21, the second interface 22, the first channel 23, the second channel 24 and the pressure detector 25 are arranged on a connector 27. The connector 27 is composed of a connector body 27A and an extension piece 27B. The first interface 21 is arranged on the connector. The connector body 27A is located at the upper end of the connector body 27A. The second interface 22 is located at the lower end of the connector body 27A. The first channel 23 is located inside the connector body 27A and communicates with the first interface 21 and the second interface 22. The second channel 24 is located inside the extension piece 27B. The pressure detector 25 is located at the end of the extension piece 27B away from the connector body 27A and communicates with the outside world.

The structure of the above-mentioned specific embodiment can achieve the following benefits:

1. The present invention's reverse flow detection device utilizes a pressure detector 25 to instantly detect reverse flow during the feeding process. Once an abnormality is detected, an alarm mechanism is immediately activated, alerting medical personnel or caregivers to conduct prompt inspections and treatment. This effectively prevents complications such as aspiration, ensuring the safety and effectiveness of feedings for patients. Furthermore, when used in home care settings, family members can care for their patients with greater peace of mind.

2. The present invention's reflux detection device, when not in use, allows for venting of air through the pressure detector 25 if necessary. Simultaneously, the pressure detector 25 triggers an alarm system, alerting caregivers to take appropriate care measures.
