Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to an anti-blocking tube device for an enteral nutrition pump. Background Art

[0002] In clinical applications, enteral nutrition pumps, as an important device for providing patients with essential nutritional support, are widely used for patients who are unable or unwilling to eat. However, during the long-term delivery of nutrient solutions, pipeline blockages often occur due to factors such as the complex composition of the nutrient solution, differences in the patient's physical condition, and the material of the pipeline. This not only affects the smooth delivery of the nutrient solution, but may also endanger the patient's life and health. In clinical practice, medical staff are required to regularly use a syringe to inject saline into the pipeline for flushing. This traditional method increases the workload of medical staff, increases their workload burden, and increases medical risks. Utility Model Content

[0022] The following examples further illustrate the content of the present invention, but should not be construed as limiting the present invention. Without departing from the spirit and essence of the present invention, modifications or replacements made to the methods, steps or conditions of the present invention are within the scope of the present invention.

[0023] In some embodiments, as Figure 1 As shown, an anti-blocking tube device for an enteral nutrition pump comprises:

[0024] The saline passage 1 has an input end connected to a first container 9 filled with physiological saline. The main passage 3 includes a thickened connecting section 301 and a delivery section 302, which are connected in sequence. One end of the thickened connecting section 301 is connected to a second container 8 filled with nutrient solution. The output end of the saline passage 1 is fixedly connected to the thickened connecting section 301, and the free end of the delivery section 302 is connected to the patient's intestinal catheter via a peristaltic pump 4.

[0025] The saline passage 1 is provided with a first switch valve 101 , and the thickened connecting section 301 is provided with a second switch valve 303 on the pipeline between the second container 8 and the output end of the saline passage 1 .

[0026] In this embodiment, the pipelines all use medical-grade transparent hoses, and the diameter of the thickened connecting section 301 is larger than that of the delivery section 302. This can reduce the resistance of the nutrient solution during the delivery process and ensure that no blockage occurs in the thickened connecting section 301.

[0027] During use, when delivering nutrient solution, the first on-off valve 101 is kept closed and the second on-off valve 303 is opened. Under the action of the peristaltic pump 4, the nutrient solution is delivered from the second container 8 through the thickened connecting section 301 and the delivery section 302 to the patient's enteral catheter. After a period of operation, the second on-off valve 303 can be closed and the first on-off valve 101 opened. Under the action of the peristaltic pump 4, physiological saline is then flushed from the first container 9 through the saline passage 1 and the thickened connecting section 301 into the delivery pipeline. This method effectively removes residual nutrient solution from the pipeline and prevents blockage.

[0028] By controlling the opening and closing of the first switch valve 101 and the second switch valve 303, the salt water and nutrient solution are alternately delivered. This alternating delivery mechanism can effectively flush out residues and accumulations in the pipeline, prevent them from forming blockages, and ensure smooth delivery of the nutrient solution.

[0029] In some embodiments, as Figure 4As shown, to reduce the burden on staff, a microprocessor can be used to automatically control the opening and closing of the first and second on-off valves 101 and 303. The specific technical solution is as follows: the first and second on-off valves 101 and 303 are solenoid valves. The enteral nutrition pump anti-blocking tube device also includes a microprocessor, and the first and second on-off valves 101 and 303 are both electrically connected to the microprocessor. The microprocessor includes a timer unit, which is used to set the opening and closing times of the first and second on-off valves.

[0030] In some embodiments, as Figure 2 As shown, in order to enhance the anti-blocking effect, a pressure pump 102 is further provided on the saline passage 1. The pressure pump 102 is connected to the input end or the middle section of the saline passage 1 to provide stable pressure to the saline.

[0031] In this embodiment, in order to better flush the pipeline, a pressure pump 102 is provided on the brine passage 1. The pressure pump can significantly increase the flow rate and pressure of brine when passing through the pipeline, further enhancing the flushing effect on residues and accumulations in the pipeline.

[0032] In actual application, medical staff can set the appropriate flushing cycle and flushing duration through the user interface of the microprocessor according to the specific situation of the patient and the composition of the nutrient solution. For example, for nutrient solutions that are prone to clogging or patients with weak constitutions, the flushing cycle can be shortened or the flushing duration can be extended to improve the anti-clogging effect and reduce the patient's discomfort. In addition, in order to facilitate medical staff to observe and record the operating status of the equipment, a display screen can be set on the anti-clogging pipe device. The display screen can display information such as the delivery status of saline and nutrient solution, flushing cycle and flushing duration in real time, helping medical staff to fully understand the operation of the equipment and deal with possible abnormal situations in a timely manner. Preferably, the timer unit is configured to open the first switch valve once every 5 minutes, and the opening time is 30 seconds.

[0033] In some embodiments, as Figure 3 As shown, a flow sensor 7 is also provided on the inner wall of the main passage.

[0034] The flow sensor 7 can monitor the flow of the nutrient solution on the main passage. When an abnormal flow is detected, the first switch valve 101 can be controlled to open to flush the pipeline.

[0035] In some embodiments, the enteral nutrition pump anti-blocking tube device further comprises an alarm system electrically connected to the microprocessor. When the flow sensor 7 detects an abnormal flow of the nutrient solution, the alarm system will emit an audible and visual alarm to remind medical staff to take timely action.

[0036] In some implementations, such as Figure 5The invention also provides an anti-blocking device for an enteral nutrition pump, which includes a platform provided with a channel for accommodating the saline channel 1, the nutrient solution channel, and the main channel 3. The first switch valve 101 and the second switch valve 303 are respectively provided on both sides of the saline channel and the nutrient solution channel. In this embodiment, the first switch valve and the second switch valve are both small hose squeeze-type solenoid valves.

[0037] The small hose squeeze solenoid valve can be one of the models PSK-1015NC, PSK-1015NO, and PSK-1015W produced by Takasago Electric Co., Ltd. The flow sensor 7 is disposed in the channel of the main passage 3. In this embodiment, the flow sensor 7 is an ultrasonic flow sensor. The ultrasonic module can be one of the models TUF-2000M, Dalian Haifeng TDS-100H, and NZ-TUC-2000. The microprocessor, power supply, and other components are integrated into the device.

[0038] During use, the saline passage 1 and the nutrient solution passage are simply snapped into their corresponding grooves. Compared to the previous embodiment, this greatly simplifies the operation process and improves efficiency. Furthermore, because the solenoid valve and flow sensor are both located outside the hose, maintenance and replacement become more convenient and sanitary. Unlike the previous embodiment, the anti-blocking tube device for enteral nutrition pumps in this embodiment is reusable.

[0039] Although the present invention has been described in detail above through general explanations, specific embodiments, and tests, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
