[0024] Example 1

[0025] A liquid food feeding device comprises a containing barrel 1, a feeding tube 2 and a pump 4, wherein the containing barrel 1 comprises a barrel body, a vacuum cover 13 and a pull ring 133, wherein the vacuum cover 13 has the same shape as the cross section of the barrel body, a pull ring 133 is arranged on the outer side of the vacuum cover 13, and the vacuum cover 13 is also provided with a hooker 3 matched with the pull ring 133, the barrel body comprises an upper barrel body 11 and a lower barrel body 12, the upper barrel body 11 and the lower barrel body 12 are matched and installed, the lower barrel body 12 is provided with a feeding hole penetrating the bottom of the lower barrel body 12, a connecting portion 121 matched with the feeding tube 2 is also arranged at the feeding hole position on the outer side of the bottom of the lower barrel body 12, and the pump 4 is arranged on the feeding tube 2.

[0026] In this embodiment, the liquid food is pumped into the patient's stomach by the pump 4. At the same time, the pump 4 drives the vacuum cover 13 to move forward. The external atmospheric pressure will push the vacuum cover 13 forward to clean up the food residues hanging on the inner wall of the barrel as much as possible and ensure that no food is wasted.

[0027] The lower barrel body 12 in the present invention is made of food grade stainless steel.

[0028] In this embodiment, the lower barrel 12 is required to crush food, and the material of the lower barrel 12 is preferably stainless steel. Its function is that the strength of stainless steel can withstand some scratches during the crushing of food, and the barrel will not be broken due to the hammering of the cooking stick.

[0029] In the present invention, a telescopic limiting device 5 is further provided on the inner side of the upper barrel body 11 near the barrel mouth.

[0030] The telescopic limiting device 5 of the present invention comprises a spring 51 and a stainless steel ball 52 . The spring 51 is arranged in the side wall of the upper barrel body 11 , and the spring 51 is connected to the stainless steel ball 52 at a side close to the inner wall of the upper barrel body 11 .

[0031] In this embodiment, the telescopic limit device 5 is used to limit the vacuum cover 13 to prevent the vacuum cover 13 from falling out. When the vacuum cover 13 is placed horizontally on the hospital bed, the telescopic limit device 5 will limit the patient's breathing and will not affect the vacuum cover 13 from being pushed back and causing the vacuum cover 13 to fall out; at the same time, when used by the nursing staff, it will retract backward and the vacuum cover 13 can be easily pulled out through the hook 3 to fill the food into the storage bucket 1.

[0032] The holding bucket 1 of the present invention is also provided with a cooking stick that matches the shape of the holding bucket 1 and is used to crush food in the holding bucket 1 .

[0033] In this embodiment, the cooking stick is a cooking stick with a crushing blade, which can crush the food in the bucket 1 into a paste to make it more convenient for the patient to eat.

[0034] The hook 3 of the present invention comprises an integrally formed elbow 31 and a long handle 32 , and the length of the long handle 32 is not less than the depth of the containing bucket 1 .

[0035] In this embodiment, the hook 3 is used to cooperate with the pull ring 133 to pull out the vacuum cover 13. It is longer than the bucket 1 to prevent the hands from getting contaminated on the inner wall of the bucket 1. Preferably, the long handle 32 is longer than the depth of the bucket 1 by more than 10 cm. This length is convenient for the nursing staff to hold it with one hand and pull it outward. In addition, in this embodiment, when the length of the hook 3 is limited, a ring handle is provided at the end of the long handle 32 away from the elbow 31, so that the user can put his fingers into it for operation.

[0036] The pump machine 4 in the present invention is a peristaltic pump, and the peristaltic pump is provided with an external speed regulating switch 41.

[0037] In this embodiment, the preferred pump 4 is a peristaltic pump. The clean and pollution-free fluid of the peristaltic pump only passes through and contacts the hose of the peristaltic pump. Because the transported substance only contacts the hose of the peristaltic pump, it is easy to be replaced and disinfected; constant flow, high precision, adjustable flow; corrosion resistance, the peristaltic pump can transport various fluids, such as organic solvents and corrosive liquids. Some corrosive liquids will invade and decompose mechanical pumps such as impeller pumps, and the peristaltic pump can replace the pump tube of different materials to achieve the transportation of different types of liquids, which can effectively prevent the substances in the food from corroding the pipeline; good sealing, idling, dry operation, the peristaltic pump can run dry for a long time, without water transportation, and can also transport air, gas-liquid-solid three-phase mixed transportation; with self-priming ability, it can be self-priming, no need to fill the pump, no need to empty. Due to the principle of the peristaltic pump, the pump wheel will press the pump tube, and the liquid will generate negative pressure at the inlet end of the pump tube during the displacement of the pump wheel, thereby sucking in the liquid, so the peristaltic pump can be self-priming, without filling the pump and emptying. The characteristics of the peristaltic pump fully meet the standards for conveying liquid food, and as a preferred option it can achieve better results.

[0038] In this embodiment, an external speed regulating switch 41 is preferably used. The speed regulating switch controls the current and can control the frequency of the peristaltic pump. If the speed regulating switch is controlled by the patient himself, the pumping frequency can be adjusted according to his own situation to prevent choking on liquid food.

[0039] Working principle: Place the feeding tube 2 into the patient's mouth or perform nasogastric feeding according to the situation, and put liquid food or food materials into the holding bucket 1. Liquid food is fed directly. If food materials are used, a cooking stick can be inserted into the holding bucket 1 to break the food materials, and the food materials are processed until they can pass through the feeding tube 2; buckle the vacuum cover 13 at the opening of the holding bucket 1 and ensure that it passes over the position of the telescopic device; then the device can be placed on the bed, and the external speed control switch 41 of the peristaltic pump is handed over to the patient or the patient's family, who can start and stop the feeding by themselves; after the feeding is completed, use the hook 3 to hook the pull ring 133 on the vacuum cover 13 and pull it outward for cleaning.
