[0044] See also Figures 1 to 13 As shown, the present invention provides a nutrient solution delivery device for assisting the care of esophageal cancer patients, comprising a mounting seat 1, wherein a fixing portion 2 is provided inside the mounting seat 1, and the fixing portion 2 can squeeze and fix a nutrient bag placed inside to prevent the nutrient bag from shifting during the operation of the device;

[0045] A driving part 3 is provided inside the fixing part 2, and the driving part 3 reciprocates inside the mounting seat 1. During the reciprocating movement of the driving part 3, the nutrient solution inside the nutrient bag can be squeezed to flow;

[0046] The driving part 3 is also provided with a stirring part 4 for rotation. The stirring part 4 can rotate by using the power of the reciprocating movement of the driving part 3. The rotation of the stirring part 4 further promotes the flow of the nutrient solution inside the nutrient bag.

[0047] The mounting base 1 is provided with a delivery portion 5 inside, which can be connected to the inlet end of the nutrition bag and can extract the nutrition liquid inside the nutrition bag and deliver it to the patient's body;

[0048] A support portion 6 is provided at the lower end of the mounting seat 1, and the support portion 6 provides support for the mounting seat 1, so that the entire device is in an inclined state during operation, so that the nutrient solution inside the nutrient bag is always inclined in the direction of the conveying portion 5;

[0049] The conveying part 5 includes a conveying motor 501, a driving shaft 502, a conveying seat 503, a rotating frame 504, an extrusion wheel 505, a conveying tube 506 and a limit knob 507. The conveying motor 501 is fixedly connected to the inside of the mounting seat 1, and the conveying motor 501 is electrically connected to the control panel inside the mounting seat 1. The control panel is connected to the mains electricity, and the connected equipment is powered and controlled through the control panel. The lower end of the driving shaft 502 is fixedly connected to the output end of the conveying motor 501, and the conveying seat 503 is assembled on the mounting seat 1. Internally, the rotating frame 504 is rotatably set inside the conveying seat 503, and the interior of the rotating frame 504 can be inserted into the upper end of the driving shaft 502, a plurality of extrusion wheels 505 are provided, and the extrusion wheels 505 are rotatably set inside the rotating frame 504, the conveying tube 506 is set inside the conveying seat 503, and the outer edge of the conveying tube 506 contacts the outer edge of the extrusion wheel 505, and the limit knob 507 is rotatably set inside the mounting seat 1, and the upper end of the limit knob 507 cooperates with the upper end of the conveying seat 503.

[0050] Specifically, when it is necessary to deliver nutrient solution to the esophageal cancer patient, the nutrient bag needs to be placed inside the opened fixing part 2, and the output tube of the nutrient bag needs to be connected to the delivery part 5, and then the fixing part 2 needs to be rotated closed to fix the nutrient bag inside the fixing part 2.

[0051] Then, the reciprocating movement of the driving part 3 inside the fixing part 2 causes the nutrient solution inside the nutrient bag to flow, and at the same time, the driving part 3 can heat the nutrient bag in contact, so that the nutrient solution inside the nutrient bag is at an optimal delivery temperature;

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

[0053] Then, the conveying motor 501 of the conveying unit 5 drives the driving shaft 502 to rotate, and 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 squeezing wheel 505 to squeeze the outer edge of the conveying tube 506, so that the entire conveying tube 506 is deformed, so that the nutrient solution inside the conveying tube 506 is discharged into the patient's body, completing the delivery of the nutrient solution;

[0054] At the same time, after the delivery of the nutrient solution is completed, it is necessary to rotate the limit knob 507 so that the limit knob 507 releases the limit lock on the delivery seat 503, and then the delivery seat 503 can be taken out of the mounting seat 1, and a new delivery seat 503 can be replaced, so as to avoid the continuous use of the delivery tube 506 inside the delivery seat 503 and cause infection to the patient, and at the same time, the delivery part 5 can be quickly put into use, thereby improving the operation efficiency;

[0055] After the new conveying seat 503 is installed into the interior of the mounting seat 1, the rotating frame 504 is inserted into the upper end of the driving shaft 502 to complete the docking of the rotating frame 504 and the driving shaft 502, and the limit knob 507 is rotated so that the limit knob 507 limits and fixes the conveying seat 503 inside the mounting seat 1.

[0056] See also Figure 4 and Figure 5 As shown, a limit groove is provided at the upper end of the driving shaft 502, and a docking hole matching the limit groove is provided inside the rotating frame 504. By plugging the limit groove and the rotating frame 504 together, the stability of the driving shaft 502 when driving the rotating frame 504 can be ensured.

[0057] See also Figures 1 to 3 As shown, a limiting ridge is provided at the upper end of the limiting knob 507. By rotating the limiting knob 507 to the conveying seat 503, the limiting ridge and the driving shaft 502 form a diagonal limit at the conveying seat 503, thereby ensuring that the conveying seat 503 can be stably limited inside the mounting seat 1, and preventing the conveying seat 503 from detaching from the inside of the mounting seat 1 during the operation of the driving shaft 502.

[0058] See also Figures 1 to 3 as well as Figure 6 As shown, the fixing part 2 includes a fixing plate 201, a rotating plate 202, a limiting cover 203, an extrusion block 204 and an elastic extrusion member 205, the fixing plate 201 is fixedly connected to the mounting seat 1, the rotating plate 202 is rotatably connected to the fixing plate 201, the limiting cover 203 is fixedly connected to the fixing plate 201, the extrusion block 204 is slidably arranged inside the fixing plate 201, and the elastic extrusion member 205 is arranged between the fixing plate 201 and the extrusion block 204;

[0059] The rotating plate 202 can be rotated to open and close at the fixed plate 201, and the rotation and closure of the rotating plate 202 at the fixed plate 201 can be locked by the lock limit on the upper part of the mounting seat 1. At the same time, the extrusion block 204 is subjected to the elastic extrusion force of the elastic extrusion member 205. The extrusion block 204 applies pressure to the nutrient bag to achieve extrusion and fixation of the nutrient bag to avoid displacement of the nutrient bag during the operation of the equipment.

[0060] See also Figure 2 , Figure 3 as well as 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 screw 302 is driven to rotate by the driving motor 301, 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 reciprocate 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 deform slightly. 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 part 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. A plurality of racks 401 are fixedly arranged inside the mounting seat 1. The rotating gear 402 is rotatably arranged inside the driving seat 303 and the rotating seat 304, and the outer edge of the rotating gear 402 is meshed with the rack 401. The fixed seat 403 is fixedly connected with the rotating gear 402. The adjusting bolt 404 is rotatably arranged inside the fixed seat 403. The interior of the adjusting seat 405 is threadedly connected with the outer edge of the adjusting bolt 404. One end of the stirring rod 406 is slidably connected with 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 meshed 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 to deform, and the nutrient solution is further mixed and flowed.

[0065] The heating function of the electric heating rod 305 can transfer heat to the contacted nutrient bag to heat the nutrient solution in the nutrient bag. The flow of the nutrient solution can be used to mix the high-temperature nutrient solution and the low-temperature nutrient solution, so that the internal temperature of the nutrient solution is uniform, thereby improving the comfort of the patient when using the nutrient solution and helping the patient to better absorb the nutrient solution.

[0066] When the stirring amplitude of the stirring part 4 needs to be adjusted, the adjusting bolt 404 needs to be rotated. During the rotation, the adjusting bolt 404 can drive the adjusting seat 405 to slide inside the fixed seat 403. The sliding of the adjusting seat 405 can drive the stirring rod 406 to move together, thereby changing the distance between the stirring rod 406 and the electric heating rod 305, thereby changing the distance and strength of the stirring rod 406 squeezing the nutrient bag.

[0067] See also Figures 6 to 8 as well as Figures 10 to 12 As shown, the interior of the driving seat 303 and the rotating seat 304 is provided with a limiting groove that cooperates with the rack 401. The cooperation between the rack 401 and the limiting groove can provide guidance and limitation for the sliding of the driving seat 303 and the rotating seat 304, thereby ensuring the driving seat 303 and the rotating seat 304, and avoiding the driving seat 303 and the rotating seat 304 from deviating and getting stuck during the movement.

[0068] See also Fig.11 and Fig.12 As shown, the outer edge of the electric heating rod 305 is rotatably connected to the axis of the rotating gear 402, and the rotating gear 402 takes the electric heating rod 305 as the rotating axis. During the rotation of the rotating gear 402, the electric heating rod 305 will not be driven to rotate together, thereby ensuring 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 process of the driving seat 303 and the rotating seat 304 being driven by the driving screw 302, the stirring rod 406 is eccentrically arranged, and can squeeze the nutrient bag when the stirring rod 406 rotates to the nutrient bag, thereby promoting the flow of nutrient solution inside the nutrient bag, thereby promoting the uniform temperature of the nutrient solution inside the nutrient bag.

[0069] See also Fig.11 and Fig.12 As shown, compensation grooves are provided inside both ends of the stirring rod 406, and the inside of the compensation groove is slidably connected with the inside of the adjustment seat 405. When one end of the stirring rod 406 is moved by the adjustment seat 405, the stirring rod 406 is tilted, and the inside of the compensation groove slides with the inside of the adjustment seat 405 to compensate for the height difference between the adjustment seat 405, so that the stirring rod 406 is always connected with the adjustment seat 405.

[0070] See also Figure 3 and Fig.13As shown, the support portion 6 includes a support foot 601 and a support frame 602, the support foot 601 is rotatably connected to the mounting seat 1, one end of the support frame 602 is fixedly connected to the mounting seat 1, and the other end of the support frame 602 is matched with the inside of the support foot 601;

[0071] First, rotate the support foot 601 to the required support angle, and then rotate the support frame 602 to fit into the fixed groove at 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 equipment is in a tilted state during operation, and the nutrient solution inside the nutrient bag is always tilted toward the direction of the conveying part 5, ensuring that the nutrient solution can be completely discharged and avoiding waste of nutrient solution.

[0072] The working principle of the present invention is as follows: when it is necessary to deliver nutrient solution to patients with esophageal cancer, the nutrient bag needs to be placed inside the opened fixing part 2, and the output pipe of the nutrient bag needs to be connected to the delivery part 5, and then the fixing part 2 is rotated closed to fix the nutrient bag inside the fixing part 2.

[0073] Then, the reciprocating movement of the driving part 3 inside the fixing part 2 causes the nutrient solution inside the nutrient bag to flow, and at the same time, the driving part 3 can heat the nutrient bag in contact, so that the nutrient solution inside the nutrient bag is at an optimal delivery temperature;

[0074] Then, the support part 6 is rotated and adjusted to make the mounting seat 1 in an inclined state, so that the nutrient solution in the nutrient bag always flows in the direction of the conveying part 5.

[0075] Then, the conveying motor 501 of the conveying unit 5 drives the driving shaft 502 to rotate, and 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 squeezing wheel 505 to squeeze the outer edge of the conveying tube 506, so that the entire conveying tube 506 is deformed, so that the nutrient solution inside the conveying tube 506 is discharged into the patient's body, completing the delivery of the nutrient solution;

[0076] At the same time, after the delivery of the nutrient solution is completed, it is necessary to rotate the limit knob 507 so that the limit knob 507 releases the limit lock on the delivery seat 503, and then the delivery seat 503 can be taken out of the mounting seat 1, and a new delivery seat 503 can be replaced to avoid continuous use of the delivery tube 506 inside the delivery seat 503 and cause infection to the patient;

[0077] After the new conveying seat 503 is installed into the interior of the mounting seat 1, the rotating frame 504 is inserted into the upper end of the driving shaft 502 to complete the docking of the rotating frame 504 and the driving shaft 502, and the limit knob 507 is rotated so that the limit knob 507 limits and fixes the conveying seat 503 inside the mounting seat 1.

[0078] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
