[0002] In the process of clinical medical care, critically ill patients or patients with unclear consciousness cannot eat independently. In order to maintain their vital signs, a liquid food delivery device is often used to inject liquid food into the patient's body to provide the necessary food and nutrition for the patient. At present, when delivering food and nutrition to patients, liquid food is generally used. The common specific operation is that medical staff or the patient's family members use a syringe to repeatedly draw in and push out liquid food to feed the patient's stomach. Such an operation is very frequent, inefficient, and cannot ensure the uniform delivery of liquid food, which increases the workload of medical staff. The existing technology uses a micro-infusion pump to replace manual operation, but there are problems such as high usage costs. At the same time, in order not to damage the patient's stomach and other organs, it is generally necessary to ensure that the temperature of the liquid food is cooled to within 50°C before feeding the patient. Since it is inevitable to use a variety of auxiliary components and the conveying pipeline is long in the liquid food device, the temperature of the liquid food drops during the process of flowing out of the liquid food bag to the user's body and cannot reach the required temperature for use.

[0054] Preferably, the cross-section of the filtering cylinder is U-shaped.

[0055] A through hole 323 is provided in the middle of the top 321 of the filtering cylinder. The through hole 323 communicates with the middle of the filtering cylinder 32 respectively. A plurality of outwardly extending mounting ribs 325 are provided on the outer periphery of the top 321 of the filtering cylinder. The filtering cylinder 32 is detachably arranged in the cavity 31-1 along a plurality of grooves 31-2 through a plurality of mounting ribs 325. A gap is provided between the outer periphery of the top 321 of the filtering cylinder and the inner side wall of the cavity 31-1, which is beneficial to the disassembly and assembly operation of the filtering cylinder 32.

[0056] Refer to Figure 2 、 Figure 5 As shown, a first liquid inlet 33-1 and a first delivery pipe 326 are provided on the top of the top cover 33. One end of the first delivery pipe 326 is embedded in the first liquid inlet 33-1. The first delivery pipe 326 communicates with the cavity 31-1. The top of the first delivery pipe 326 is a plug 326-1, and the plug 326-1 has an inclined socket 326-2. The first delivery pipe 326 pierces the barrier plug 12-1 of the liquid food outlet 12 through the inclined opening 326-2, so that the liquid food in the liquid food bag 1 flows into the cavity 31-1 for filtration.

[0057] At the bottom of the cylindrical container 31, there is a first liquid outlet 31-3 and a second delivery pipe 327. The second delivery pipe 327 is embedded in the first liquid outlet 31-3, and the second delivery pipe 327 communicates with the cavity 31-1. As Figure 4 shown, at the end of the second delivery pipe 327, there is a first internal thread connector 327-1.

[0058] Preferably, the surface of the filter cartridge is honeycomb-shaped.

[0059] Preferably, the number of the several grooves is at least three to ensure the connection stability of the cylindrical filter cartridge in the cavity. The number of the several installation ribs corresponds to the number of the several grooves.

[0060] Referring to Figure 8 shown, the speed regulation device 4 includes a speed regulation top cover 41, a speed regulation base 42, a base 43, and a diaphragm 44.

[0061] Combined with Figure 9 shown, at the bottom of the speed regulation top cover 41, there is a speed regulation base accommodation hole 413 that penetrates inward. At the center of the top of the speed regulation top cover 41, there is a second liquid inlet 412 and a third delivery pipe 412-2. One end of the third delivery pipe 412-2 is embedded in the second liquid inlet 412. The second liquid inlet 412 communicates with the speed regulation base accommodation hole 413, and the speed regulation base accommodation hole 413 and the speed regulation top cover 41 are coaxial.

[0062] Combined with Figure 11 shown, on the top of the speed regulation base 42, there is a downward concave diaphragm installation position 421 concentrically arranged. The diaphragm 44 is arranged in the diaphragm installation position 421. The speed regulation base 42 is sleeved on the liquid discharge convex column 432. At the bottom of the speed regulation base 42, there is a liquid discharge convex column installation hole 422. On the inner side wall of the liquid discharge convex column installation hole 422, there are limit grooves 422-1 distributed along the circumferential direction and matched with the limit columns 432-1. There is a channel 424 between the diaphragm installation position 421 and the liquid discharge convex column installation hole 422.

[0063] During use, when the liquid food flows into the diversion groove 415 from the second liquid inlet 412 and enters the liquid discharge through hole 432-2, a pressure difference is generated between the second liquid inlet 412 and the liquid discharge through hole 432-2. In the initial state, the remaining amount of liquid food in the liquid food bag is sufficient, so that the flow rate of the liquid food flowing through the diversion groove 415 is large. At this time, the outlet fluid pressure in the liquid discharge through hole 432-2 is less than the inlet fluid pressure of the second liquid inlet 412. The pressure difference between the two causes the diaphragm 44 to bend and sink downward and contact the inclined surface 433-1 of the upright rib column through the channel 424, shortening the distance between the diaphragm 44 and the liquid discharge through hole 432-2, and restricting the flow rate of the liquid food flowing into the liquid discharge through hole 432-2 through the top of the liquid discharge convex column 432. As the amount of liquid food in the liquid food bag decreases, the pressure at the second liquid inlet 412 decreases accordingly, and the pressure at the liquid discharge through hole 432-3 increases accordingly. The diaphragm 44 moves away from the liquid discharge through hole 432-2, reducing the restriction on the flow rate of the liquid food flowing into the liquid discharge through hole 432-2. During use, since the remaining amount in the liquid food bag 1 will continuously decrease, the pressure difference between the second liquid inlet 412 and the liquid discharge through hole 432-2 will continuously change, and the bending of the diaphragm 44 can establish a balanced flow rate in the speed regulating device to ensure the quantitative delivery of the liquid food.

[0064] The speed regulating device 4 is connected to the patient's gastric tube through the fourth delivery tube 435 to deliver the liquid food into the stomach. During use, the air in the patient's stomach will enter the device along with the fourth delivery tube 435. The air in the patient's stomach will cause the diaphragm 44 to move upward. The circular convex part 414 and the limit convex part 414-1 are arranged in contact with the diaphragm 44, restricting the upward movement of the diaphragm 44 and ensuring the sealing performance in the channel 424, preventing the liquid food from flowing back upward into the diaphragm mounting position 421.

[0065] An annular groove 423 is formed between the diaphragm mounting position 421 and the speed regulating base 42. A number of liquid discharge channels 422-2 that penetrate to the bottom of the speed regulating base 42 are arranged in an annular array in the annular groove 423. One side end of the bottom of the number of liquid discharge channels 422-2 is axially provided with a liquid discharge groove 422-3, and the liquid discharge groove 422-3 penetrates to the liquid discharge convex column mounting hole 422. When the speed regulating base 42 is arranged on the base 43, the liquid discharge groove 422-3 is aligned with the arc-shaped liquid rising channel 432-2, realizing the flow of the liquid food from the liquid discharge channel 422-2 to the liquid discharge through hole 432-3.

[0066] Combined with Figure 9 As shown, the inner side wall of the annular groove 423 is provided with first and second positioning convex edges 422-4 and 422-5 that limit the rotation angle of any positioning convex edge 415-1 in the speed regulating base accommodating hole 413. One side end of the first positioning convex edge 422-4 is aligned with one side of any liquid discharge channel 422-2 in the annular groove 423, and the second positioning convex edge 422-5 is symmetrically arranged with the first positioning convex edge 422-4 with the other side of the liquid discharge channel 422-2 as the center.

[0067] Preferably, the numbers of the liquid discharge channels and arc-shaped liquid lifting channels should be respectively set correspondingly, and in this embodiment, three groups are respectively set correspondingly.

[0068] Reference Figure 8 , Figure 4 As shown, an externally threaded connecting pipe 412-3 is embedded in the other end of the third delivery pipe 412-2, and the externally threaded connecting pipe 412-3 of the third delivery pipe 412-2 is threadedly connected to the first internally threaded connector 327-1 of the second delivery pipe to achieve the circulation of liquid food between the two devices.

[0069] A concave edge 413-1 for inserting the base 43 is provided on the side wall near the bottom of the speed regulating base accommodating hole 413, and the side wall from the concave edge 413-1 to the bottom of the speed regulating base accommodating hole 413 is an inclined surface 413-2 inclined outwardly, and the inclined surface 413-2 is used to guide the base 43 to insert into the concave edge 413-1.

[0070] Reference Figure 9 As shown, a circular protrusion 414 is provided at the top center of the speed regulating base accommodating hole 413, and at least three limiting protrusions 414-1 are provided in a circular array on the surface of the circular protrusion 414. A guide groove 415 is provided in an array on the top of the speed regulating base accommodating hole 413, and one side of the guide groove 415 axially penetrates to the second liquid inlet 412. The guide groove 415 is provided between any two adjacent limiting protrusions 414-1, and limiting ridges 415-1 corresponding to the annular groove 423 are provided on three sides of the bottom of the other side of the guide groove 415.

[0071] When the speed regulating base 42 is inserted into the limiting columns 432-1 of the base 43 through the limiting groove 422-1, the limiting concave edge 415-1 is inserted into the annular groove 423. In the initial state, one side of the guide groove 415 is staggered with the drainage channel 422-2. During operation, the base 43 is rotated to make the positioning convex edge 415-1 rotate along the annular groove 423 so that one side of the guide groove 415 overlaps with the drainage channel 422-2 or adjusts the overlapping angles to control the flow speed of the liquid food.

[0072] Preferably, the guide groove is fan-shaped.

[0073] Reference Figure 8 , Figure 10 , Figure 17 As shown, the top edge of the base 43 has a flange 431, and a speed regulating base installation recess 431-6 is provided on the top of the base 43, and the speed regulating base 42 is arranged in the installation recess 431-6.
