The "in one preferred embodiment" appearing in various places in the specification is not intended to refer to the same embodiment, nor is it intended to exclude other embodiments that can be combined with other embodiments.

[0043] Third, the present application is described in detail in conjunction with the schematic drawings, and in the detailed description of the embodiments of the present application, the sectional view of the device structure is partially enlarged without the general proportion for the convenience of illustration, and the schematic drawings are only examples, which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0044] Please refer to Figures 1 to 13 As shown in the drawings, the present application provides a nutritional liquid delivery device for assisting in the nursing of esophageal cancer patients, which comprises a mounting seat 1, and a fixed part 2 is arranged in the mounting seat 1. The fixed part 2 can extrude and fix the nutritional bag placed inside to avoid the nutritional bag from deviating during the operation of the device.

[0045] A driving part 3 is arranged in the fixed part 2, which reciprocally moves in the mounting seat 1. During the reciprocating movement of the driving part 3, the nutritional liquid in the nutritional bag can be extruded to flow.

[0046] An agitating part 4 is further arranged in the driving part 3, which can rotate by the power of the reciprocating movement of the driving part 3. The rotation of the agitating part 4 further promotes the flow of the nutritional liquid in the nutritional bag.

[0047] A delivery part 5 is arranged in the mounting seat 1, which can be connected with the inlet end of the nutritional bag and can extract the nutritional liquid in the nutritional bag to be delivered into the body of the patient.

[0048] A supporting part 6 is arranged at the lower end of the mounting seat 1, which provides support for the mounting seat 1, so that the whole device is in an inclined state during the operation, so that the nutritional liquid in the nutritional bag is always inclined to the direction of the delivery part 5.

[0049] The conveying part 5 comprises a conveying motor 501, a driving shaft 502, a conveying seat 503, a rotating frame 504, a plurality of extrusion wheels 505, a conveying pipe 506 and a limiting knob 507. The conveying motor 501 is fixedly connected to the inside of the mounting seat 1, and electrically connected to a control panel in the mounting seat 1. The control panel is connected to a commercial power supply, and supplies power and controls the connected devices through the control panel. The lower end of the driving shaft 502 is fixedly connected to the output end of the conveying motor 501. The conveying seat 503 is assembled in the inside of the mounting seat 1. The rotating frame 504 is rotatably arranged in the inside of the conveying seat 503, and the inside of the rotating frame 504 can be inserted into the upper end of the driving shaft 502. The extrusion wheels 505 are rotatably arranged in the inside of the rotating frame 504. The conveying pipe 506 is arranged in the inside of the conveying seat 503, and the outer edge of the conveying pipe 506 is in contact with the outer edge of the extrusion wheel 505. The limiting knob 507 is rotatably arranged in the inside of the mounting seat 1, and the upper end of the limiting knob 507 is matched with the upper end of the conveying seat 503.

[0050] Specifically, when the esophageal cancer patient needs to be fed, the feeding bag is placed in the inside of the opened fixing part 2, and the output pipe of the feeding bag is connected to the conveying part 5. Then, the fixing part 2 is rotated to be closed, so that the feeding bag is fixed in the inside of the fixing part 2.

[0051] Then, the reciprocating movement of the driving part 3 in the inside of the fixing part 2 promotes the flow of the nutrient solution in the inside of the feeding bag. At the same time, the driving part 3 can heat the feeding bag in contact, so that the nutrient solution in the inside of the feeding bag is at the best conveying temperature.

[0052] Then, the adjusting support part 6 is rotated to make the mounting seat 1 in an inclined state, so that the nutrient solution in the inside of the feeding bag always flows to the direction of the conveying part 5.

[0053] Then, the conveying motor 501 of the conveying part 5 drives the driving shaft 502 to rotate. The rotation of the driving shaft 502 drives the rotating frame 504 to rotate in the inside of the conveying seat 503. The rotating frame 504 drives the extrusion wheels 505 to extrude the outer edge of the conveying pipe 506, so that the whole conveying pipe 506 is deformed, and the nutrient solution in the inside of the conveying pipe 506 is discharged into the patient's body, and the feeding of the nutrient solution is completed.

[0054] At the same time, after the feeding of the nutrient solution is completed, the limiting knob 507 is rotated to release the limiting locking of the conveying seat 503. Then, the conveying seat 503 can be taken out of the inside of the mounting seat 1. A new conveying seat 503 can be replaced, so that the conveying pipe 506 in the inside of the conveying seat 503 is not continuously used to cause the infection of the patient. At the same time, the conveying part 5 can be quickly put into use, and the operation efficiency is improved.

[0055] After the new conveying seat 503 is installed into the inside of the mounting seat 1, the rotating frame 504 is inserted into the upper end of the driving shaft 502, the interface of the rotating frame 504 and the driving shaft 502 is completed, the rotating limiting knob 507 is rotated, and the conveying seat 503 is limited and fixed in the inside of the mounting seat 1.

[0056] As shown in Figure 4 and Figure 5 , the upper end of the driving shaft 502 is provided with a limiting groove, and the inside of the rotating frame 504 is provided with an interface hole matched with the limiting groove. Through the insertion of the limiting groove and the rotating frame 504, the stability of the driving shaft 502 for driving the rotating frame 504 can be ensured.

[0057] As shown in Figures 1 to 3 , the upper end of the limiting knob 507 is provided with a limiting ridge. By rotating the limiting knob 507 to the conveying seat 503, the limiting ridge and the driving shaft 502 form an angle limiting at the conveying seat 503, so that the conveying seat 503 can be stably limited in the inside of the mounting seat 1, and the conveying seat 503 is prevented from separating from the inside of the mounting seat 1 during the operation of the driving shaft 502.

[0058] As shown in Figures 1 to 3 and Figure 6 , the fixed part 2 includes a fixed plate 201, a rotating plate 202, a limiting cover 203, an extrusion block 204 and an elastic extrusion piece 205. The fixed plate 201 is fixedly connected with the mounting seat 1, the rotating plate 202 is rotatably connected with the fixed plate 201, the limiting cover 203 is fixedly connected with the fixed plate 201, the extrusion block 204 is slidably arranged in the inside of the fixed plate 201, and the elastic extrusion piece 205 is arranged between the fixed plate 201 and the extrusion block 204.

[0059] The rotating plate 202 can be rotatably opened and closed at the fixed plate 201. The rotation of the rotating plate 202 at the fixed plate 201 can be locked by the lock catch on the upper part of the mounting seat 1, and at the same time, the extrusion block 204 is elastically extruded by the elastic extrusion piece 205. The extrusion block 204 applies pressure to the nutrient bag, realizes extrusion and fixation of the nutrient bag, and avoids deviation of the nutrient bag during operation of the equipment.

[0060] As shown in Figure 2 , Figure 3 and Figures 6 to 8As shown, the driving part 3, the driving motor 301, the driving screw 302, the driving seat 303, the rotating seat 304 and the electric heating rod 305, the driving motor 301 is fixedly connected to the inside of the mounting seat 1, the driving screw 302 is rotatably set inside the mounting seat 1, and one end of the driving screw 302 is fixedly connected to the output end of the driving motor 301, the driving seat 303 is slidably set inside the mounting seat 1, and the interior of one end of the driving seat 303 is threadedly connected to the outer edge of the driving screw 302, one end of the rotating seat 304 is rotatably connected to one end of the driving seat 303, and the electric heating rod 305 is fixedly set inside the driving seat 303 and the rotating seat 304.

[0061] The driving motor 301 and the electric heating rod 305 are electrically connected to the control panel;

[0062] The driving motor 301 drives the driving screw 302 to rotate, and the rotation of the driving screw 302 drives the driving seat 303 and the rotating seat 304 to move together. As the output end of the driving motor 301 drives the driving screw 302 to rotate forward and reverse, the driving seat 303 and the rotating seat 304 move back and forth inside the mounting seat 1; the movement of the driving seat 303 and the rotating seat 304 can move along the outer edge of the nutrient bag, causing the nutrient bag to be slightly deformed. The deformation causes the heated nutrient solution inside the nutrient bag to flow, thereby promoting uniform mixing of the nutrient solution inside the nutrient bag.

[0063] See also Figures 8 to 12 As shown, the stirring portion 4 includes a rack 401, a rotating gear 402, a fixed seat 403, an adjusting bolt 404, an adjusting seat 405 and a stirring rod 406. The rack 401 is fixedly provided with a plurality of teeth inside the mounting seat 1. The rotating gear 402 is rotatably provided inside the driving seat 303 and the rotating seat 304, and the outer edge of the rotating gear 402 is engaged with the rack 401. The fixed seat 403 is fixedly connected to the rotating gear 402. The adjusting bolt 404 is rotatably provided inside the fixed seat 403. The interior of the adjusting seat 405 is threadedly connected to the outer edge of the adjusting bolt 404. One end of the stirring rod 406 is slidably connected to the interior of the adjusting seat 405.

[0064] During the movement of the driving seat 303 and the rotating seat 304, the rotating gear 402 is carried along with the movement. Since the rotating gear 402 is engaged with the rack 401, the rotating gear 402 rotates. The rotation of the rotating gear 402 can drive the stirring rod 406 to rotate on the outer edge of the electric heating rod 305. When the stirring rod 406 rotates to a position in contact with the nutrient bag, the nutrient bag is further squeezed and deformed, further promoting mixing and flow of the nutrient solution.

[0065] The heat generated by the electric heating rod 305 can be transmitted to the nutrition bag in contact, and the nutrition liquid in the nutrition bag can be heated. The mixing flow of the high-temperature nutrition liquid and the low-temperature nutrition liquid is realized by the flow of the nutrition liquid, so that the internal temperature of the nutrition liquid is uniform, and the comfort of the patient using the nutrition liquid is improved, and the patient can better absorb the nutrition liquid.

[0066] When the stirring amplitude of the stirring part 4 needs to be adjusted, the adjusting bolt 404 needs to be rotated. The adjusting bolt 404 can drive the adjusting seat 405 to slide in the fixed seat 403 during rotation. The sliding of the adjusting seat 405 can drive the stirring rod 406 to move together, change the distance between the stirring rod 406 and the electric heating rod 305, and change the distance and strength of the stirring rod 406 pressing the nutrition bag.

[0067] Please refer to Figures 6 to 8 and Figures 10 to 12 It is shown that the inside of the driving seat 303 and the rotating seat 304 is provided with a limit groove matched with the toothed rail 401. The cooperation of the toothed rail 401 and the limit groove can provide guidance and limitation for the sliding of the driving seat 303 and the rotating seat 304, so as to ensure the driving seat 303 and the rotating seat 304, and avoid the driving seat 303 and the rotating seat 304 from being offset during movement to cause jamming.

[0068] Please refer to Figure 11 and Figure 12 It is shown that the outer edge of the electric heating rod 305 is rotationally connected at the axis of the rotating gear 402. The rotating gear 402 takes the electric heating rod 305 as the rotation axis. During the rotation of the rotating gear 402, the electric heating rod 305 will not rotate together, so as to ensure the working stability of the electric heating rod 305. The stirring rod 406 is fixedly arranged at a position away from the axis of the rotating gear 402. During the driving of the driving seat 303 and the rotating seat 304 by the driving screw 302, the stirring rod 406 is arranged eccentrically, so as to press the nutrition bag when the stirring rod 406 rotates to the nutrition bag, promote the flow of the nutrition liquid in the nutrition bag, and thus promote the temperature uniformity of the nutrition liquid in the nutrition bag.

[0069] Please refer to Figure 11 and Figure 12 It is shown that the inside of the both ends of the stirring rod 406 is provided with a compensation groove. The inside of the compensation groove is slidably connected with the inside of the adjusting seat 405. During the movement of one end of the stirring rod 406 by the adjusting seat 405, the stirring rod 406 is inclined, the inside of the compensation groove is slidably connected with the inside of the adjusting seat 405 to compensate for the height difference between the adjusting seats 405, so that the stirring rod 406 is always connected with the adjusting seat 405.

[0070] Please refer to Figure 3 and Figure 13As shown, the support part 6 comprises a support foot 601 and a support frame 602, the support foot 601 is rotationally connected with the mounting base 1, one end of the support frame 602 is fixedly connected with the mounting base 1, and the other end of the support frame 602 is matched with the inside of the support foot 601;

[0071] First, the support foot 601 is rotated to the required supporting angle, then the support frame 602 is rotated and clamped into the fixed groove inside the support foot 601, so that a stable triangular structure is formed between the support frame 602 and the support foot 601, so that the device is in an inclined state during operation, so that the nutrient liquid inside the nutrient bag is always inclined to the direction of the conveying part 5, ensuring that the nutrient liquid can be completely discharged, avoiding waste of nutrient liquid.

[0072] The working principle of the present application is that when it is necessary to deliver nutrient liquid to an esophageal cancer patient, the nutrient bag needs to be placed inside the opened fixed part 2, and the output pipe of the nutrient bag is connected with the conveying part 5, then the fixed part 2 is rotated to be closed to fix the nutrient bag inside the fixed part 2,

[0073] Then the reciprocating movement of the driving part 3 inside the fixed part 2 promotes the flow of the nutrient liquid inside the nutrient bag, and the driving part 3 can heat the nutrient bag in contact, so that the nutrient liquid inside the nutrient bag is at the best delivery temperature;

[0074] Then the adjusting support part 6 is rotated to make the mounting base 1 be in an inclined state, so that the nutrient liquid inside the nutrient bag always flows to the direction of the conveying part 5

[0075] Then the conveying motor 501 of the conveying part 5 drives the driving shaft 502 to rotate, the rotation of the driving shaft 502 drives the rotating frame 504 to rotate inside the conveying seat 503, so that the rotating frame 504 drives the extrusion wheel 505 to extrude the outer edge of the conveying pipe 506, so that the whole conveying pipe 506 is deformed, thereby making the nutrient liquid inside the conveying pipe 506 be discharged into the patient's body, completing the delivery of the nutrient liquid;

[0076] At the same time, after the delivery of the nutrient liquid is completed, the limiting knob 507 needs to be rotated to release the limiting locking of the conveying seat 503 by the limiting knob 507, then the conveying seat 503 can be taken out of the inside of the mounting base 1, a new conveying seat 503 can be replaced, avoiding continuous use of the conveying pipe 506 inside the conveying seat 503 causing infection of the patient;

[0077] After the new conveying seat 503 is installed into the inside of the mounting base 1, the rotating frame 504 is inserted into the upper end of the driving shaft 502, the butt joint of the rotating frame 504 and the driving shaft 502 is completed, the limiting knob 507 is rotated to limit and fix the conveying seat 503 inside the mounting base 1.

[0078] The above merely describes the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
