Description

Technical Field

[0001] This utility model relates to the field of intensive care technology, specifically to a liquid feeding assistance device for critically ill patients. Background Technology

[0002] Patients requiring monitoring in the intensive care unit are often bedridden and unable to care for themselves. They need assistance from hospital staff to eat and drink. Most critically ill patients can only consume liquids, and some also require oral medications. It is sometimes difficult for medical staff to feed these liquids or medications to the patients, thus increasing the workload for caregivers.

[0003] Furthermore, the process of feeding liquid food is lengthy, and the cooling of the liquid food is detrimental to the patient's health. Liquid food differs from water and may cause blockages during delivery. Current liquid feeding methods involve manually pushing the liquid food into the esophagus or using a pneumatic device. Firstly, manual pushing makes it impossible to control the amount of liquid food, causing patient discomfort. With pneumatic devices, if the piston becomes blocked, the continuously injected gas pressure increases, and when the piston suddenly becomes clear, the liquid food is pushed in rapidly, causing adverse effects. To address these issues, there is a need for a liquid food feeding aid for critically ill patients that can maintain temperature, evenly mix the liquid food, prevent blockages, and allow for controlled feeding flow. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a feeding assistance device for critically ill patients that can keep the liquid food warm, mix the liquid food evenly, prevent blockage, and control the feeding flow rate.

[0027] like Figure 1 and Figure 4 The illustrated liquid feeding aid for critically ill patients includes:

[0028] A liquid food container 1 is provided with a stirring mechanism inside. The bottom of the liquid food container 1 is provided with a liquid food outlet 102, and the top of the liquid food container 1 is provided with a vent pipe 11. A first valve 12 is provided on the vent pipe 11.

[0029] Feeding cylinder 13 is located at the bottom of the liquid feeding cylinder 1, and the liquid feeding outlet 102 is connected to the top right end of the feeding cylinder 13. A piston 16 is provided inside the feeding cylinder 13, and an electric push rod 19 is provided at the left end of the feeding cylinder 13. The movable rod 18 of the electric push rod 19 passes through the feeding cylinder 13 and is connected to the piston 16.

[0030] The feeding tube 13 is provided with a feeding tube 14 at the right end, and a second valve 15 is provided on the feeding tube 14. The feeding tube 14 is connected to the feeding hose 23.

[0031] This utility model provides a liquid feeding assistance device for critically ill patients. A stirring mechanism agitates the liquid food, preventing large volumes of food from settling at the bottom of the feeding tube 1 and preventing blockage of the feeding tube 23. This ensures the liquid food enters the patient's mouth with a suitable viscosity, facilitating swallowing. A piston-type feeding tube 13, in conjunction with a first valve 12 and a second valve 15, draws liquid food from the feeding tube 1 and injects it into the feeding tube 23 through the feeding tube 14. During feeding, a flow meter 24, in conjunction with an electric push rod 19, controls the feeding flow rate, improving feeding safety. The second valve 15 on the feeding tube 14, when closed after feeding, prevents residual liquid food from dripping from the feeding mouthpiece 25, avoiding subsequent cleaning.

[0032] In this embodiment, the liquid food tube 1 is cylindrical, and the stirring mechanism includes a stirring shaft 3 vertically arranged at the center inside the liquid food tube 1. The stirring shaft 3 is evenly arranged with multiple stirring blades 4 in the circumferential direction. The bottom of the liquid food tube 1 is provided with a rotating seat 2 that is adapted to the lower end of the stirring shaft 3. The upper end of the stirring shaft 3 is coaxially connected to the output shaft of the stirring motor 9 fixed at the top of the liquid food tube 1.

[0033] like Figures 1-3 As shown, a detachable cover 10 is provided on the top of the liquid food container 1. A stirring motor 9 is fixedly mounted on the top of the cover 10. The outer end of the output shaft of the stirring motor 9 passes through the middle of the cover 10 and is fixedly connected to a retaining sleeve 8. The retaining sleeve 8 is provided with a retaining groove 801. A retaining post 7 is fixedly mounted on the upper end of the stirring shaft 3. The retaining post 7 is adapted to the retaining groove 801. The retaining post 7 and the retaining groove 801 are polygonal prisms. The retaining sleeve 8 can drive the retaining post 7 to rotate synchronously under the drive of the stirring motor 9. A rim 1001 is provided at the bottom edge of the cover 10. The inner wall of the rim 1001 is provided with an internal thread. The outer wall of the upper end of the liquid food container 1 is provided with an external thread adapted to the internal thread. The cover 10 is threadedly connected to the liquid food container 1. As a further optimization, an annular sealing ring 28 is also provided below the cover 10.

[0034] A filter plate 5 is fixedly installed at the lower part of the stirring shaft 3 below the stirring blades 4, and the filter plate 5 has multiple filter holes 6. By setting the filter plate 5, large volumes of liquid food can be filtered.

[0035] like Figure 1 As shown, the bottom of the liquid food tube 1 is inclined with a slope 101, which is higher on the left and lower on the right. The liquid food outlet 102 is located at the lowest point of the slope 101.

[0036] The feeding tube 13 is cubical. When the piston 16 is located at the rightmost end of the feeding tube 13, it can completely block the liquid food outlet 102, preventing liquid food from entering the left side of the piston 16. As a further optimization, the piston 16 is wrapped with a silicone pad 17.

[0037] A flow meter 24 is provided on the feeding hose 13, and a feeding nozzle 25 is provided at the free end of the feeding hose 13.

[0038] The liquid food container 1 is equipped with an insulating sleeve 27 on its outer side. A heating tube 26, which is a spiral-shaped electronic heating tube, is disposed between the liquid food container 1 and the insulating sleeve 27. A temperature sensor is disposed on the inner wall of the liquid food container 1. By setting up the heating tube 26 and the temperature sensor, the liquid food in the liquid food container 1 can be kept at a constant temperature, which is beneficial to the patient's health.

[0039] The first valve 12 and the second valve 15 are either one-way valves or solenoid valves. When the first valve 12 is a one-way valve, the vent pipe 11 can only allow the medium to flow into the feed container 1. When the second valve 15 is a one-way valve, the feed outlet pipe 14 can only allow the medium to flow to the outside of the feed container 13. When the first valve 12 and the second valve 15 are solenoid valves, when the movable rod 18 of the electric push rod 19 drives the piston 16 to move to the left, the first valve 12 on the vent pipe 11 opens and the second valve 15 on the feed outlet pipe 14 closes, drawing liquid food from the feed container 1. When the movable rod 18 of the electric push rod 19 drives the piston 16 to move to the right, the first valve 12 on the vent pipe 11 closes and the second valve 15 on the feed outlet pipe 14 opens, injecting liquid food into the feeding hose 23 through the feed outlet pipe 14, and feeding is performed through the feeding mouthpiece 25.

[0040] The feeding tube 13 is mounted on the base plate 21, and support blocks 22 are provided on both sides of the feeding tube 13 between the feed container 1 and the base plate 21.
