[0016] By employing the above technical solution, the present invention has at least the following beneficial effects: This application provides a liquid food administration device for critically ill patients. A partition is installed within the feeding tube, dividing the chamber into a mixing chamber and a feeding chamber. These chambers are connected by a delivery pipe with a one-way guide component installed at the bottom of the partition. The one-way guide component allows liquid food to flow only from the mixing chamber to the feeding chamber. Driven by a driving component, a negative pressure is generated in the feeding chamber. Under this negative pressure, the one-way guide component opens, allowing liquid food from the mixing chamber to automatically enter the feeding chamber, balancing the pressure in both chambers. The mixing chamber then stops supplying liquid food to the feeding chamber. During this process, the one-way guide component prevents air backflow from the feeding tube side, thus avoiding air entry at the source. During feeding, the liquid food in the feeding chamber is directed to the patient's feeding end only through the feeding chamber under the pushing pressure of the driving component, preventing material backflow and air mixing. Significantly reducing the amount of air inhaled by patients during feeding can significantly reduce the incidence of gastrointestinal discomfort such as bloating and abdominal pain, while effectively avoiding the risk of aspiration pneumonia caused by air entering the airway with liquid food, thus improving the safety and comfort of liquid food feeding.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See also Figures 1 to 5 As shown in the embodiment of this application, a liquid food administration device for critically ill patients is provided, including a feeding cylinder 1, a partition 2, and a drive assembly 3. The feeding cylinder 1 is hollow to form a chamber. The partition 2 is axially disposed in the chamber to divide the chamber into a stirring chamber and a feeding chamber. A through groove 201 is provided on the end face of the partition 2, and a conveying pipe 203 is installed in the through groove 201. A one-way guiding member 202 is provided on the conveying pipe 203. The drive assembly 3 is disposed in the feeding chamber, and the driving end of the drive assembly 3 extends to the outside of the feeding cylinder 1. The drive assembly 3 is used to generate negative pressure in the feeding chamber so that the liquid food in the stirring chamber enters the feeding chamber through the one-way guiding member 202.

[0024] A partition 2 is installed in the chamber of the feeding tube 1, dividing the chamber into a stirring chamber and a feeding chamber. The stirring chamber and the feeding chamber are connected by a delivery pipe 203 with a one-way guide component 202 installed at the bottom of the partition 2. The one-way guide component 202 only allows liquid food to flow from the stirring chamber to the feeding chamber. Under the drive of the drive component 3, a negative pressure is generated in the feeding chamber. The one-way guide component 202 is opened under the negative pressure, and the liquid food in the stirring chamber is automatically replenished into the feeding chamber through the one-way guide component 202, so that the pressure in the stirring chamber and the feeding chamber reaches equilibrium. The stirring chamber stops supplying liquid food to the feeding chamber. During this process, there is no air backflow channel on the feeding chamber side due to the blocking effect of the one-way guide component 202, which prevents air from entering from the source. During the feeding stage, the liquid food in the feeding chamber can only be directionally delivered to the patient's feeding end through the feeding tube 105 under the pushing pressure of the drive component 3, without material backflow or air mixing channels. Significantly reducing the amount of air inhaled by patients during feeding can significantly reduce the incidence of gastrointestinal discomfort such as bloating and abdominal pain, while effectively avoiding the risk of aspiration pneumonia caused by air entering the airway with liquid food, thus improving the safety and comfort of liquid food feeding.

[0025] The feeding cylinder 1 is hollow inside to form a chamber; the partition 2 is arranged axially in the chamber to divide the chamber into a stirring chamber and a feeding chamber, the stirring chamber and the feeding chamber being the same size; the bottom end of the partition 2 is sealed to the bottom of the chamber to divide the chamber into a stirring chamber and a feeding chamber.

[0026] The partition 2 has a through groove 201 on its end face, and a conveying pipe 203 is installed in the through groove 201. A one-way guiding component 202 is provided on the conveying pipe 203. The installation of the conveying pipe 203 in the through groove 201 allows the mixing chamber and the feeding chamber to be connected under certain conditions. The liquid food mixed in the mixing chamber is then fed into the feeding chamber through the one-way guiding component 202 on the conveying pipe 203.

[0027] The drive assembly 3 is disposed within the feeding chamber, with its drive end extending to the outside of the feeding tube 1. The drive assembly 3 generates negative pressure within the feeding chamber, allowing liquid food from the mixing chamber to enter the feeding chamber via the one-way guide member 202. When the drive assembly 3 moves toward the top end of the feeding tube 1, it generates negative pressure within the feeding chamber, driving the one-way guide member 202 to open under the negative pressure, allowing liquid food from the mixing chamber to enter the feeding chamber. When the drive assembly 3 moves toward the bottom end of the feeding tube 1, it allows liquid food from the feeding chamber to flow out of the feeding chamber and be fed to the patient.

[0028] Specifically, the unidirectional guide component 202 is unidirectional; it only allows opening in one direction to prevent liquid food entering the feeding chamber from flowing back into the mixing chamber.

[0029] In another embodiment, the drive assembly 3 includes a push plate 303 and a connecting rod 302. The push plate 303 is disposed in the feeding chamber, and the first end of the connecting rod 302 is connected to the surface of the push plate 303, and the second end extends at least partially to the outside of the feeding tube 1.

[0030] In order to ensure the sealing between the push plate 303 and the feeding cavity, the structural shape of the push plate 303 is the same as that of the feeding cavity; and a sealing strip is pasted on the circumferential side wall of the push plate 303 to further ensure the sealing at the joint.

[0031] The push plate 303 is disposed in the feeding chamber and can move axially relative to the feeding chamber. The first end of the connecting rod 302 is connected to the surface of the push plate 303, and the second end extends at least partially to the outside of the feeding tube 1. By driving the second end of the connecting rod 302, the push plate 303 can be moved axially along the feeding chamber.

[0032] Specifically, the length of the connecting rod 302 is greater than the height of the feeding tube 1, so as to ensure that the second end of the connecting rod 302 can extend to the outer side of the top of the feeding tube 1 to form a drive end.

[0033] In another embodiment, the drive assembly 3 further includes a handle 301 located outside the feeding tube 1 and connected to the second end of the connecting rod 302.

[0034] A handle 301 is provided at the second end of the connecting rod 302. By pulling the handle 301, the push plate 303 can be moved along the axial direction of the feeding cylinder 1 via the connecting rod 302.

[0035] In another embodiment, the liquid food feeding device further includes a stirring assembly 4, which includes a stirring paddle 402 disposed within a stirring chamber. The stirring shaft of the stirring paddle 402 extends at least partially to the outside of the feeding cylinder 1, and the stirring paddle 402 rotates relative to the feeding cylinder 1. The stirring paddle 402 employs a spiral blade design, which can generate an axial vortex when rotating, ensuring uniform mixing of the liquid food and preventing nutrient solution sedimentation and stratification.

[0036] The stirring paddle 402 rotates relative to the feeding cylinder 1, and a bearing is installed between the two to reduce wear.

[0037] The stirring paddle 402 extends to the outer end of the feeding cylinder 1 and is provided with a handle 401. The stirring paddle 402 rotates relative to the stirring chamber by rotating the handle 401.

[0038] Specifically, the 401 handle has an anti-slip texture, allowing medical staff to rotate it with one hand.

[0039] Specifically, the agitator 402 is made of medical-grade silicone, which can withstand high-temperature sterilization and avoid cross-infection.

[0040] In another embodiment, the liquid food administration device further includes a temperature control component 5, which includes a controller, a heating plate 502, and a temperature measuring module 501. The heating plate 502 is disposed on the inner wall of the feeding cylinder 1 and located inside the mixing chamber. The temperature measuring module 501 is disposed at the bottom of the feeding cylinder 1 for measuring the temperature of the liquid food inside the mixing chamber. The controller is integrated on the feeding cylinder 1, and the temperature measuring module 501 and the heating plate 502 are respectively connected to the controller.

[0041] The heating plate 502 is located on the inner wall of the feeding tube 1. The heating plate 502 is arc-shaped and can fit into the inner wall of the feeding tube 1, making it easy to install and eliminating any dead corners for cleaning.

[0042] The bottom of the feeding tube 1 is equipped with a temperature measuring module 501, which is used to measure the temperature of the liquid food in the mixing chamber to ensure the temperature of the liquid food and avoid the liquid food being too low or too high, which would have an adverse effect on the patient.

[0043] The temperature measuring module 501 and the heating plate 502 are connected to the controller. The output of the temperature measuring module 501 is connected to the input of the controller, and the output of the controller is connected to the heating plate 502. When the temperature measuring module 501 detects that the temperature of the liquid food in the mixing chamber is lower than the temperature threshold, it feeds back the temperature signal to the controller. The controller then controls the heating plate 502 to start heating the liquid food in the mixing chamber to the temperature threshold. When the temperature measuring module 501 detects that the temperature of the liquid food has reached the temperature threshold again, it feeds back the temperature signal to the controller, and the controller then controls the heating plate 502 to stop heating.

[0044] Specifically, the temperature measurement module 501 is a probe-type temperature sensor with a sensing accuracy of ±0.5℃. The controller uses an STM32F103 microcontroller; the heating plate 502 is model KRS-DH with a power of 50W.

[0045] For easy observation, an indicator light is installed on the feeding cylinder 1. When the temperature is lower than the temperature threshold, the controller will activate the indicator light to alert medical staff. To ensure even temperature distribution of the liquid food, the liquid food can be stirred by rotating the stirring paddle 402 after the indicator light is on, which helps to diffuse the temperature of the liquid food and ensures that the temperature of the liquid food in the cylinder is uniform, with a temperature difference of ≤1℃, thus solving the problem of localized overheating in traditional devices.

[0046] In another embodiment, the feeding tube 1 includes a tube body 101 and a tube cover 102. The outer wall of the open end of the tube body 101 is provided with a locking assembly 6, and the tube cover 102 is placed on the tube body 101 so that the tube cover 102 is locked on the tube body 101 by the locking assembly 6.

[0047] The locking component 6 makes it easier and more convenient to open the cylinder cover 102 relative to the cylinder body 101.

[0048] In this embodiment of the application, the cross-sectional shape of both the cylinder body 101 and the cylinder cover 102 is circular.

[0049] The cylinder cover 102 has two through holes. One through hole is used to install the connecting rod 302. The diameter of the handle 301 is larger than the diameter of the connecting rod 302 to prevent the drive assembly 3 from falling off the cylinder cover 102 after the cylinder cover 102 is opened. The other through hole is used to install the stirring paddle 402. A bearing is installed between the stirring shaft of the stirring paddle 402 and the through hole of the cylinder cover 102.

[0050] Specifically, the 101 feeding tube is made of medical-grade PP material, has a volume of 500ml, and has scale lines on the surface for easy and precise control of the feeding amount.

[0051] In another embodiment, a feeding tube 105 is provided at the bottom of the tube body 101, and the feeding tube 105 communicates with the feeding cavity. Liquid food in the feeding cavity is supplied to the patient through the feeding tube 105. The feeding tube 105 is made of food-grade silicone tubing with an inner diameter of 8mm, and can be quickly connected to a nasogastric tube or feeding head.

[0052] In another embodiment, the locking assembly 6 includes a telescopic assembly and a locking tongue 603. The outer wall of the cylinder body 101 is provided with a first fixing groove 103, and the inner wall of the cylinder cover 102 is provided with a second fixing groove 104. The end of the telescopic assembly is disposed in the first fixing groove 103, and the end of the telescopic assembly opposite to the first fixing groove 103 is provided with a locking tongue 603. The locking tongue 603 is engaged in the second fixing groove 104 of the cylinder cover 102 so that the cylinder cover 102 is locked onto the cylinder body 101.

[0053] The outer wall of the cylinder body 101 has a first fixing groove 103, which is arranged opposite to each other on both sides of the outer wall of the cylinder body 101; the inner wall of the cylinder cover 102 has a second fixing groove 104, which is arranged opposite to each other on both sides of the inner wall of the cylinder cover 102. The first fixing groove 103 is used to install the telescopic component; the second fixing groove 104 is used to cooperate with the telescopic component so that the cylinder cover 102 can be detachably installed at the open end of the cylinder body 101.

[0054] In another embodiment, the telescopic assembly includes a telescopic tube 602 and an elastic element 601. The elastic element 601 is disposed inside the telescopic tube 602. One end of the telescopic tube 602 and the elastic element 601 is disposed inside the first fixing groove 103. A locking tongue 603 is provided at the end of the telescopic tube 602 and the elastic element 601 opposite to the first fixing groove 103.

[0055] The elastic element 601 is disposed inside the telescopic tube 602, that is, the elastic element 601 and the telescopic tube 602 are coaxially disposed. One end of the telescopic tube 602 and the elastic element 601 is disposed in the first fixing groove 103, that is, one end of the telescopic tube 602 and the elastic element 601 is welded to the bottom of the first fixing groove 103. A locking tongue 603 is provided at the end of the telescopic tube 602 and the elastic element 601 away from the first fixing groove 103, that is, the end of the telescopic tube 602 and the elastic element 601 away from the first fixing groove 103 is welded to the locking tongue 603. After the cap 102 is placed on the body 101, the elastic element 601 and the telescopic tube 602 extend, and the locking tongue 603 is moved towards the cap 102 so that one end of the locking tongue 603 is engaged in the second fixing groove 104 of the cap 102. When it is necessary to open the cap 102, pressing the other end of the locking tongue 603 compresses the elastic element 601 and the telescopic tube 602, separating the locking tongue 603 from the second fixing groove 104 on the cap 102, and the cap 102 opens from the body 101. This achieves quick locking and unlocking of the cap 102 and the body 101. Compared with traditional threaded connections or snap-fit ​​structures, unlocking can be completed simply by pressing the locking tongue 603, allowing medical staff to operate with one hand.

[0056] The outer surface of the cylinder 101 is provided with a sealing ring. After locking, the cylinder cover 102 and the cylinder 101 are sealed together.
