The pressure mechanism compresses the air inwardly, and under the effect of the pressure, the air is compressed toward the interior of the liquid food storage chamber through the gap portion of the first connecting plate, thereby squeezing the liquid food in the liquid food storage chamber. When the air pressure in the liquid food storage chamber is sufficient, under the effect of the pressure, the air pressure pushes the spring downward to compress, thereby pushing the second connecting plate downward, driving the disc and the connecting column downward, so that the connecting column drives the stirring device to rotate, so as to stir the liquid food in the storage chamber, thereby squeezing the air toward the interior of the liquid food storage chamber through the pressure mechanism, thereby squeezing the liquid food in the liquid food supply device while squeezing and stirring the liquid food in the process of feeding the patient with liquid food, thereby improving the patient's comfort and user experience.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A liquid food supply device for gastroenterology, comprising: a liquid food storage chamber, a stirring mechanism, a guiding mechanism, an extruding mechanism and a discharging pipe; the stirring mechanism is arranged inside the liquid food storage chamber, the top of the liquid food storage chamber is connected to the extruding mechanism, and the bottom of the liquid food storage chamber is connected to the upper end of the discharging pipe; The extrusion mechanism is connected to the guide mechanism arranged on the upper end surface of the liquid food storage cavity through a connecting pipe; The stirring mechanism is arranged at the lower end of the guiding mechanism, and the air is compressed into the guiding mechanism through the extrusion mechanism, and the guiding mechanism drives the stirring mechanism to rotate under the impetus of the air force. At the same time, the air force guides the liquid food to move downward and supplies the liquid food to the gastroenterology patient through the discharge pipe.

[0008] The present application discloses a liquid food supply device for gastroenterology. In actual use, a certain amount of liquid food is added to the liquid food storage chamber through the feed port of the liquid food storage chamber, and then the air is compressed to the guide mechanism through the extrusion mechanism. Under the action of air power, the air power drives the guide mechanism to rotate to stir the liquid food in the liquid food storage chamber. At the same time, the air power guides the liquid food to move downward to supply the liquid food to gastroenterology patients through the discharge pipe. In the process of feeding the patient with liquid food, the liquid food in the liquid food supply device is squeezed and stirred at the same time, thereby improving the patient's comfort and use experience. Through the newly designed device, the extrusion mechanism, the guide mechanism and the air pressure are combined.

One end of the spring is fixedly connected to the bottom of the blade of the first connecting plate, and the other end is connected to the second connecting plate. The disc and the connecting column are connected in turn to the bottom of the second connecting plate.

Under the extrusion action, the air is compressed into the inside of the liquid food storage chamber through the gap part of the first connecting plate, so as to squeeze the liquid food in the liquid food storage chamber. When the air pressure in the liquid food storage chamber is sufficient, under the extrusion action, the air pressure pushes the spring to move downward, and then pushes the second connecting plate to move downward, driving the disc and the connecting column to move downward, so that the connecting column drives the stirring device to rotate, so as to stir the liquid food from the storage chamber, thereby squeezing the air into the liquid food storage chamber through the extrusion mechanism, so as to squeeze and stir the liquid food in the liquid food supply device during the process of feeding the patient with liquid food, thereby improving the patient's comfort and user experience.

[0050] As attached Figure 1-7 As shown, a liquid food supply device for gastroenterology in the embodiment of the present application comprises: a liquid food storage chamber 1, a stirring mechanism 2, a guiding mechanism, an extrusion mechanism 301 and a discharge pipe 4; a feed port is provided at the upper end of the liquid food storage chamber 1, and the stirring mechanism 2 is arranged inside the liquid food storage chamber; the top of the liquid food storage chamber is connected to the extrusion mechanism, and the discharge pipe 4 is arranged at the bottom of the liquid food storage chamber, and the discharge pipe 4 is used to discharge the liquid food through the discharge pipe and finally deliver it into the patient's stomach; The squeezing mechanism 301 is connected to the guiding mechanism arranged on the upper end surface of the liquid food storage chamber 1 through the connecting pipe 302; The stirring mechanism 2 is arranged at the lower end of the guiding mechanism, and the air is compressed into the guiding mechanism through the extrusion mechanism 301. The guiding mechanism drives the stirring mechanism to rotate under the impetus of the air force, and the air force guides the liquid food to move downward.

[0051] The present application discloses a liquid food supply device for gastroenterology. In actual use, a certain amount of liquid food is added to the liquid food storage chamber through the feed port of the liquid food storage chamber, and then the air is compressed toward the guide mechanism through the extrusion mechanism. Under the action of air power, the air power drives the lower guide mechanism to rotate to stir the liquid food in the liquid food storage chamber. At the same time, the air power guides the liquid food to move downward, so that during the process of feeding the patient with liquid food, the liquid food in the liquid food supply device is squeezed and stirred, thereby improving the patient's comfort and use experience. Through the newly designed device, the extrusion mechanism, the guide mechanism and the air pressure are combined. Under the action of the air pressure, the stirring mechanism is pushed to stir, and at the same time, the air pressure also presses the liquid food into the stomach to improve the patient's experience and eating comfort.

[0052] The guiding mechanism includes a first connecting plate 303, a second connecting plate 305, a disc 306, a connecting column 307 and a plurality of springs 304; The first connecting plate 303, the second connecting plate 305, the disc 306, a plurality of connecting columns 307 and a plurality of springs 304 are arranged at the end of the connecting tube; the first connecting plate 303 is in the shape of a fan blade, one end of the spring 304 is fixedly connected to the bottom of the blade of the first connecting plate 303, and the other end is connected to the second connecting plate 305, the disc 306 and the connecting column 307 are connected in turn to the bottom of the second connecting plate, and the disc 306 and the connecting column 307 are used to drive the stirring mechanism 2 to rotate under the impetus of aerodynamic force.

[0053] Specifically, the end of the connecting tube 302 is a funnel-shaped structure, and the first connecting plate 303, the second connecting plate 305, the disc 306, a plurality of connecting columns 307 and a plurality of springs 304 are arranged in the funnel-shaped structure of the connecting tube. The first connecting plate 303 is a fan-shaped structure. The first connecting plate is used to compress the air into the liquid food storage chamber according to the pressure of the extrusion airbag and cause the air pressure to push the second connecting plate downward. One end of the spring 304 is fixedly connected to the bottom of the blade of the first connecting plate, and the other end is connected to the second connecting plate. The disc 306 and the connecting column 307 are connected to the bottom of the second connecting plate in sequence. The disc 304 and the connecting column 307 are used to control the stirring mechanism 2 to stir the liquid food according to the pushing action of the second connecting plate.

[0054] Specifically, the first connecting rod 303 is fixedly connected to the inner wall of the connecting tube 302, one end of the spring 304 is fixedly connected to the lower end of the first connecting rod 303, and the other end is fixedly connected to the second connecting plate 305, and the second connecting plate 305 is slidably connected to the tube wall of the connecting tube 302, so that the second connecting plate slides downward when dragged by air pressure, allowing the air pressure to enter the liquid food storage cavity to achieve the extrusion of the liquid food.

[0055] The present application discloses a liquid food supply device for gastroenterology. In actual use, a certain amount of liquid food is added to the liquid food storage chamber through the feed port, and then the air is compressed into the inside by squeezing the airbag. Under the squeezing action, the air is compressed into the liquid food storage chamber through the gap part of the first connecting plate, so as to squeeze the liquid food in the liquid food storage chamber. When the air pressure in the liquid food storage chamber is sufficient, under the squeezing action, the air pressure pushes the spring downward to compress, and then pushes the second connecting plate downward to move, driving the disc and the connecting column downward, so that the connecting column drives the stirring device to rotate, so as to stir the liquid food from the storage chamber, thereby squeezing the air into the liquid food storage chamber through the squeezing mechanism, so as to squeeze and stir the liquid food in the liquid food supply device during the process of feeding the patient with liquid food, thereby improving the patient's comfort and use experience. Through the newly designed squeezing mechanism, the squeezing mechanism is combined with the air pressure. While the squeezing and stirring mechanism is stirred by the air pressure, the air pressure also presses the liquid food into the stomach, thereby improving the patient's experience and eating comfort.

[0056] It should be noted that in the present application, the main function of the liquid food storage chamber for the storage tank is to store liquid food, and its shape, size, and material can be specifically designed according to the actual use scenario and needs of the liquid food supply. The existing liquid food storage chamber is usually cylindrical stainless steel. The advantage of this shape is that it is easy to manufacture and clean, and can provide a large storage capacity. In addition, the cylindrical storage chamber can also be easily connected and integrated with other components (such as a discharge pipe, a stirring mechanism, etc.). The advantages of this stainless steel material are corrosion resistance, high temperature resistance, easy cleaning and disinfection, and suitable for use in a medical environment. In addition, stainless steel also has good mechanical strength and durability, and can withstand frequent use and cleaning. Exemplarily, in an embodiment of the present invention, the liquid food storage chamber adopts a structure in which the upper section is cylindrical and the lower end is conical, and the material is stainless steel. The liquid food flows out from the tip of the conical structure of the liquid food storage chamber to the discharge pipe and is delivered to the stomach through the extrusion action of the extrusion device and the stirring action of the stirring device in the present application. In addition, the liquid food storage cavity can also be made of cylindrical, square, irregular or other materials and shapes that can store liquid food and meet actual usage requirements.

[0057] See also Figure 1 In some embodiments, a feed port is provided at the upper end of the liquid food storage chamber 1, and a sealing mechanism 101 is provided on the feed port. The feed port can be sealed through the design of the sealing mechanism, thereby preventing external impurities from entering the liquid food storage chamber, thereby increasing the overall sealing of the device.

[0058] In some embodiments, the feed port can be configured to be funnel-shaped. By designing the feed port to be funnel-shaped, food can enter the liquid food storage cavity more easily, which greatly simplifies the feeding process and improves work efficiency.

[0059] It should be noted that the sealing mechanism in the present application is used to seal the feed port of the liquid food storage chamber, and its shape, material, and size are matched according to the structure and material of the feed port. For example, the sealing mechanism can adopt a sealing cover with a threaded structure and a metal material. The sealing cover with a metal thread has the characteristics of being strong and durable, and has good sealing performance. In addition, the sealing mechanism can also use other structures such as a snap-on structure, a flip-top structure, and a rotating structure. The material can be selected from plastic, glass, rubber and other materials. As long as it can meet the user's use requirements, the feed port can be sealed and foreign impurities can be prevented from entering the liquid food storage chamber. No detailed explanation is given here.

[0060] In some embodiments, a valve 3011 is provided on the squeezing mechanism 301 , and the valve 3011 is used to control the gas to enter the interior of the guiding mechanism and increase the pressure.

[0061] Through the design of valve 3011, on the one hand, the inlet and outlet of gas can be controlled by rotating or pressing the valve to control the gas from entering the guide mechanism and increase the pressure; on the other hand, the opening of the valve can be adjusted to maintain a stable air pressure in the liquid food storage chamber to prevent gas leakage or over-inflation, thereby ensuring the stability and safety performance of the liquid food supply device for gastroenterology in this application.

[0062] It should be noted that, in some embodiments, the extrusion mechanism can use an extrusion airbag to control the gas entering the guide mechanism and increase the pressure, and the valve can adjust the opening to maintain a stable air pressure in the liquid food storage chamber to prevent gas leakage or over-inflation, thereby ensuring the stability and safety performance of the liquid food supply device for gastroenterology in the present application.

[0063] See also Figure 2-3 In some embodiments, an electric push rod 5 is provided outside the squeezing airbag, and the electric push rod is used to push the squeezing mechanism to inflate and deflate. By pushing and withdrawing the electric push rod, the valve of the squeezing mechanism and the squeezing airbag are controlled, so that the electric push control gas enters the squeezing mechanism and increases the pressure.

[0064] Through the design of the electric push rod, on the one hand, the controlled gas can be electrically pushed into the guide mechanism and increase the pressure. On the other hand, the electric push rod extrusion airbag has the advantages of precise control, high degree of automation, strong programmability, high safety and easy maintenance.

[0065] The stirring mechanism 2 is arranged inside the liquid food storage chamber 1, and the stirring mechanism 2 includes: a rotating rod 201, a plurality of stirring rods 202 and a plurality of spiral tracks 203; the plurality of stirring rods 202 are installed at fixed intervals around the outer surface of the rotating rod 201, and the plurality of spiral tracks 203 are arranged around the upper end of the rotating column 202, and the connecting column is slidably connected to the spiral track 203, and the direction of the spiral track matches the movement of the connecting column 307. The spiral track is used for the connecting column to slide in the spiral track, thereby controlling the rotation of the rotating rod, driving the stirring rod 202 to stir, and realizing the stirring of the liquid food.

[0066] In the present application, through the design of the spiral track, when the air pressure in the liquid food storage chamber is sufficient, the air pressure pushes the spring 304 to compress downward, and then pushes the second connecting plate to move downward, driving the disc and the connecting column to move downward. Since the connecting column slides on the spiral track 203 due to the downward force, it drives the spiral track 203 to rotate, so as to control the rotation of the rotating rod, drive the stirring rod 202 to stir, and realize the stirring of the liquid food.

[0067] In some embodiments, six stirring rods are installed on the outer surface of the rotating column, three spiral tracks are arranged around the upper end of the rotating column 202, and the lower end of the disc 306 is fixedly connected to three rotating columns that match the corresponding spiral tracks respectively. The air is squeezed downward by the squeezing action of the squeezing mechanism to achieve the purpose of squeezing the liquid food. The disc is pushed downward by the downward pushing action of the mechanism, and then the rotating column is driven to rotate by the sliding of the connecting column in the spiral track, thereby stirring the liquid food in the liquid food storage chamber, and finally achieving the purpose of squeezing and stirring at the same time.

[0068] In some embodiments, the stirring device 2 also includes a scraper 204, which is fixedly mounted on the end of the stirring rod 202. The end of the scraper 204 away from the stirring rod 202 contacts the inner wall of the liquid food storage chamber 1. The scraper 206 is used to scrape off the liquid food residue on the inner wall of the liquid food storage chamber as the stirring rod rotates, thereby preventing the liquid food residue from adhering to the inner wall of the storage tank and affecting the next feeding, thereby achieving a more practical effect.

[0069] In some embodiments, a backflow prevention mechanism 401 is provided at the bottom of the discharge pipe 4 .

[0070] By designing an anti-backflow mechanism at the port of the discharge pipe, on the one hand, the flow direction and pressure of the liquid food in the liquid food storage chamber can be controlled, and on the other hand, it can effectively prevent the leakage of liquid or gas, and prevent other substances such as food in the stomach from flowing back into the liquid food supply device, causing harm to the patient. In some embodiments, the anti-backflow mechanism can adopt a cross valve structure, which has a simple design, convenient operation, strong durability, and can effectively prevent other substances such as food in the stomach from flowing back into the liquid food supply device.

[0071] In some embodiments, the end of the connection tube 302 and the liquid food storage chamber 1 is connected to a bowl-shaped structure 308. The design of the bowl-shaped structure can increase the contact area of ​​the gas, effectively guide and distribute the gas flow so that it is evenly distributed in the liquid food storage chamber, and reduce eddy currents and resistance during the gas flow, thereby improving the efficiency of the gas flow.

[0072] If explanation is required, Fig.13 As shown, in some embodiments, the end of the connection between the connecting pipe 302 and the liquid food storage chamber 1 may not be provided with a bowl-shaped structure. This arrangement can also realize that under the extrusion effect, the air is compressed into the liquid food storage chamber through the gap part of the fan blade structure of the first connecting plate, thereby squeezing the liquid food in the liquid food storage chamber. When the air pressure in the liquid food storage chamber is sufficient, under the extrusion effect, the air pressure pushes the spring downward to compress, and then pushes the second connecting plate downward to move, driving the disc and the connecting column downward, so that the connecting column drives the stirring device to rotate, so as to stir the liquid food from the storage chamber, thereby squeezing the air into the liquid food storage chamber through the extrusion mechanism. However, compared with not setting a bowl-shaped structure, setting a bowl-shaped structure has a good implementation effect.

[0073] See also Figure 14-16 As shown, a liquid food supply device for gastroenterology in an embodiment of the present invention is used when nursing gastroenterology patients, and when a liquid food supply device is needed to feed liquid food to critically ill patients who are extremely weak and unable to chew food. Its specific working principle is as follows: like Fig.14 As shown, Fig.14 Schematic diagram of the internal structure of a liquid food supply device for gastroenterology in an embodiment of the present invention when no liquid food is put in. At this time, no liquid food is put in the device, the extrusion mechanism and the stirring device are both under the action of air pressure, the spring of the device is in place, and the rotating rod 307 is located at the front end of the arc track. Figure 15-16 , Fig.15 It is a schematic diagram of the internal structure of a liquid food supply device for gastroenterology in an embodiment of the present invention, in which a connecting column is pressed down to the middle of an arc track. Fig.16The invention is a schematic diagram of the internal structure of a connecting column of a liquid food supply device for gastroenterology in an embodiment of the present invention, which is pressed down to the end of the arc track. When in use, when liquid food needs to be supplied to the patient, the liquid food is manually put into the liquid food storage cavity through the feed port, and then the sealing cover is covered, and the discharge pipe is put into the patient's stomach. At this time, the air is compressed into the liquid food storage cavity by squeezing the extrusion airbag. Under the action of air pressure, the air is compressed into the liquid food storage cavity through the gap part of the first connecting plate. Then, when the air pressure in the liquid food storage cavity is sufficient, under the action of squeezing, the air pressure pushes the spring downward to compress, and then pushes the second connecting plate downward to move, driving the disc and the connecting column downward, so that the air can squeeze the liquid food into the discharge pipe 4, and at the same time, the connecting column drives the stirring device to rotate to stir the liquid food from the storage cavity, thereby realizing the squeezing of air into the liquid food storage cavity by the squeezing mechanism, and realizing the squeezing and stirring of the liquid food in the liquid food supply device during the process of feeding the patient with liquid food, thereby improving the patient's comfort and user experience.
