The feeding system includes a peristaltic pump, a weighing instrument, a drive motor, and pipelines, etc. The pipelines in each feeding system are respectively a feeding tube and a water feeding tube, and the feeding tube is connected by a feeding hose 23 and a feeding hard tube 8. The feeding hose 23 is connected in series with the feeding peristaltic pump 25, and the suction port of the feeding tube is the port of the feeding hard tube 8. Compared with the hose, it can be squeezed and deformed, and the material of the feeding hard tube has a certain structural strength. Easy to fix and insert into food. The feeding hose forms a soft body, and the feeding tube forms a rigid straw. The same water feeding pipe is also made up of two parts, the water feeding hose 22 and the water feeding hard pipe 5, and the water feeding hose 22 is correspondingly connected in series in the water feeding peristaltic pump 24. The discharge port of the feeding hose and the water feeding hose is communicated with the connecting pipe 29 by the tee joint 28, and the connecting pipe 29 is connected to the meal feeding interface 12 at the side of the cabinet.

There are two groups of weighing instruments on the lower side of the placement cavity, and the corresponding feeding hard tubes and water feeding hard tubes are food cup weighing instruments 17 and water cup weighing instruments 16 respectively, and the upper parts of the food cup weighing instruments and water cup weighing instruments are respectively The sides are respectively a food cup placement platform 10 and a water cup placement platform 7 for placing a food cup 9 and a water cup 6 . Place the food cup 9 and the water cup 6 on the table tops of the food cup placement platform and the water cup placement platform respectively, control the feeding hard tube and the water feeding hard tube to move downwards and can extend into the corresponding cups below, and the food cup and the water cup form a container. rice container. The upper side of the placement cavity is provided with a driving mechanism for driving the feeding hard pipe and the water feeding hard pipe to move up and down. The driving mechanism includes a stepping motor, a leading screw 18, a nut and a mounting bracket 19 fixed on the nut, and the leading screw 18 moves along the The upper and lower directions are vertically arranged, and the stepper motor is arranged on the upper end of the lead screw. The stepper motor drives the lead screw to rotate so as to drive the nut to move up and down along the lead screw. The nut and the mounting frame 19 move together, and the work of the stepper motor is more accurate and convenient. Control stroke. The installation frame hangs out toward both sides of the lead screw in the horizontal direction, and the feeding hard pipe and the water feeding hard pipe are respectively fixed on the overhanging sections on both sides of the installation frame, at the upper and lower positions of the lead screw. An upper limit device 20 and a lower limit device 21 are respectively provided for limiting the moving stroke of the nut. The upper and lower limit devices are used to limit the up and down travel of the nut, preventing the feeding hard pipe and the water feeding hard pipe from moving downward. Damage the food and water cups while avoiding the feeding hose and water hose moving up past the broken feeding hose and water hose.

In the water feeding system, the control module is connected between the water cup weighing instrument, the water feeding peristaltic pump and the stepper motor, and the stepper motor is driven to move down by the control module until the nut moves to the Stop at the position of the lower limit device, control the start of the water feeding peristaltic pump, and start to suck the water in the water cup. The water enters the patient's esophagus through the water feeding hard tube, water feeding hose and IOE tube. The amount of water in the tank, and the weight signal is fed back to the control module. When the water supply calculated by the control module reaches the set value, the control module controls the water feeding peristaltic pump to stop working, and makes the stepping motor work in reverse to drive the water feeding hard pipe upward. Move until the slider moves to the position of the upper limit device and stops to complete the water feeding work. The upper limit device and the lower limit device can be travel switches, and the stepper motor can be automatically powered off by touching the nut on the travel switch, or the upper and lower limit devices can also be distance sensors. When the setting value of the distance sensor is set, the distance sensor sends a closing signal to realize the automatic power-off of the stepper motor. It can also be a pressure sensor, which realizes the automatic power-off of the stepper motor by pressing the nut on the pressure sensor. Correspondingly, the structure of the feeding system is the same as that of the water feeding system, and its control module is also communicatively connected between the food cup weighing instrument, the feeding peristaltic pump and the motor. The control method is also the same. The food in this example is all liquid food. On the one hand, liquid food is convenient for patients to digest and absorb. On the other hand, it has good fluidity and can pass through the pipeline smoothly without causing pipeline blockage. Unless otherwise specified, it should be understood as liquid food. During this process, precise and quantitative feeding can be realized for patients without the need for special medical staff to supervise the whole process. When the feeding amount reaches the set value, it will automatically end. The high degree of automation of the whole machine can reduce the workload of medical staff.

The weight of feeding water and feeding weight can be displayed on the touch screen in real time. Taking water feeding as an example, the water cup weighing instrument is connected with the logic operation module in the control module and connected with the touch screen through the control module. The water cup with quantitative water is placed on the cup placement platform, and the water cup weighing instrument weighs the original weight of the sum of the water cup and the water in the cup. The logic operation module records the original weight value measured by the water cup weighing instrument, and presses the touch screen to display The zero setting key on the screen will automatically display the water feeding weight as zero. With the progress of water feeding, the amount of water in the water cup is continuously decreasing. The water cup weighing instrument weighs the real-time weight value of the sum of the water cup and the remaining water in the cup, and the logic operation module automatically calculates the difference between the original weight value and the real-time weight value. , the water feeding weight displayed on the touch screen is the difference between the two. When the water feeding weight reaches the value set in advance, the control module controls the water feeding peristaltic pump to stop working, and makes the stepping motor drive the water feeding hard pipe to move upwards out of the water surface to complete the water feeding work. In the same way, feed weighing works on the same principle as water feed weighing.

When in use, first insert one end of the IOE tube into the patient's esophagus, and the other end of the IOE tube is exposed outside the patient's body and connected to the feeding interface of the IOE feeding machine to ensure the connection between the IOE tube and the connecting tube in the body. Good to keep food from leaking out. Place the water cup containing an appropriate amount of warm water and the food cup containing an appropriate amount of food on the corresponding placement table in the placement cavity, press the zero button on the touch screen, and the values of the water feeding weight and feeding weight are displayed as zero. According to the actual situation of the patient, set the pre-feeding water weight and pre-feeding weight. After the setting is completed, press the start button, the control module will work, and the motor will drive the water hard tube and the feeding hard tube to descend until the water hard tube and the feeding hard tube The suction port of the pipe submerges to the bottom position of the water cup and the food cup and stops near the cup body respectively, and the control module controls each pump head of the water feeding peristaltic pump and the feeding peristaltic pump to perform forward rotation. Taking the water feeding work as an example, the water feeding peristaltic pump squeezes out the air in the water feeding hose through its pump head, and forms a negative pressure to absorb water through the water feeding hard pipe, water feeding hose, tee joint, connection Tube, feeding interface and IOE tube, finally enter the patient's esophagus. During the water feeding process, the water feeding weight value on the touch screen is continuously increasing. When the pre-feeding water weight value is reached, the water cup weighing instrument sends a signal to the control module, and the control module stops the water feeding peristaltic pump. And control the stepper motor to drive the hard water feeding tube to rise to move out of the water surface, complete the whole water feeding work, and finally the IOE tube is pulled out from the feeding interface and the IOE tube is pulled out from the patient's esophagus.

There are also feeding system cleaning buttons and feeding system cleaning buttons on the touch screen. Taking feeding system cleaning as an example, the specific cleaning steps are: first pour the remaining food in the food cup into the recycling container, clean the food cup, and clean the cup After cleaning, fill the food cup with an appropriate amount of boiled water with a temperature not lower than 80°C, press the feeding system cleaning button, the control module will make the feeding hard tube dive down to the bottom of the food cup, and start the feeding peristalsis to absorb the boiled water. The waste water is discharged through the drainage pipe connected to the feeding interface, and the residual food in the pipeline and IOE pipe can be removed by pumping the boiled water. Finally, replace the boiled water with a special cleaning solution, and then clean it again in the same way. After the cleaning solution is drained, plug the plug into the feeding interface.
