Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to a nursing liquid food supply device. Background Technology

[0002] Liquid nutrition support is an indispensable part of modern clinical medicine, mainly used for patients with neurological diseases, oral and maxillofacial trauma, post-gastric surgery, and other conditions requiring special feeding assistance. With advancements in medical technology and evolving nursing concepts, clinical requirements for nutritional support equipment have shifted from basic functionality to a more refined operational experience and a safer feeding process. Current medical equipment is developing towards intelligence, precision, and humanization. As a key device in long-term care, the technological innovation of liquid nutrition devices directly impacts patient recovery outcomes and quality of life.

[0003] Existing liquid food feeding devices generally lack heating and insulation functions, causing the food inside the device to gradually cool down during the feeding process. Low-temperature liquid food can irritate the patient's digestive tract mucosa, leading to gastrointestinal vasoconstriction, reduced digestive enzyme activity, and consequently, symptoms such as indigestion, abdominal distension, and abdominal pain. For postoperative or critically ill patients, cold liquid food may also induce intestinal spasms, delaying the recovery process. Some devices have added heating elements, but uneven heating results in excessively high local temperatures of the liquid food, affecting patient intake.

[0004] Therefore, we provide a nursing liquid food supply device to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a nursing liquid food supply device, including...

[0006] The feeding bucket has an openable and closable cover on its surface and a feeding tube on its bottom.

Several horizontal pipes are vertically distributed between the periphery walls of the rectangular pipe, and vertical pipes are horizontally distributed. A vertically upward-facing air supply pipe is connected to the periphery of the rectangular pipe.

[0008] A heating device, which is mounted on the cover plate, is used to transfer heat to the gas supply pipe;

[0009] The horizontal pipe is designed as a wavy pipe, and the diameter of the different horizontal pipes increases gradually from the upper layer to the lower layer. The vertical pipe is designed as a tapered pipe, and its diameter increases linearly from top to bottom, which is used to increase the contact area between the liquid food and heat at the bottom of the feeding bucket.

[0010] The present invention is further configured such that the vertical distribution density of the horizontal tube gradually increases from top to bottom, and the horizontal distribution density of the vertical tube gradually increases from near the central axis of the feeding bucket to away from the central axis.

[0011] The present invention is further configured such that the top end of the air supply pipe is coaxially and rotatably connected with the cover plate, the top end of the air supply pipe extends into the interior of the heating device, and a plurality of air supply holes are evenly opened at one end of the air supply pipe located in the inner cavity of the heating device, for introducing hot air into the stirring pipe to rapidly raise the pipe wall temperature.

The vertical pipe has a conical structure (the pipe diameter increases linearly from top to bottom) to ensure that the liquid food at the edge and bottom of the feeding bucket is fully heated.

[0015] 2. The spiral plate on the inner wall of the stirring pipe of this utility model changes with the contour of the pipe, guiding the hot air to move in a spiral along the pipe wall, changing the flow pattern of the hot air in the pipe, increasing the length of the airflow path, and the spiral structure destroys the straight flow, ensuring that the hot air fully contacts the entire pipe wall. The spiral angle of the spiral plate is 15°-30°, so that the hot air generates a secondary circulation, balancing the flow resistance and heat exchange performance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0026] Please see Figure 1 This utility model is a nursing liquid food supply device, including a feeding bucket 1. The feeding bucket 1 can be installed on the edge of the bed table or the edge of the nursing table through an adjustable clamp assembly (not shown in the figure). The bottom of the clamp is equipped with a rubber anti-slip pad to ensure the stability of the device. The clamp is equipped with a knob-type fastening bolt, which can flexibly adjust the clamping force according to the thickness of the table.

[0027] The surface of the food container 1 is equipped with an openable and closable cover 2. The cover 2 is sealed to the food container 1 by a ring-shaped silicone sealing ring. A U-shaped handle can be added to the top of the cover 2 to facilitate the opening and closing operation by medical staff.

[0028] The bottom surface is provided with a feeding tube 3, which is a flexible tube made of food-grade silicone. The feeding tube 3 is provided with a discharge valve 11 at the end of the feeding tube 3 near the feeding container 1. The discharge valve 11 is an electromagnetic induction valve, which can be remotely controlled to open and close via a foot switch or handheld controller to avoid contamination from manual operation. It is suitable for sterile care scenarios.

[0029] For further details, please refer to Figure 3 The mixing pipe 4 is made of 304 stainless steel with a polished outer wall to reduce the adhesion of liquid food.

[0030] The stirring pipe 4 includes a rectangular pipe 5 located inside the feeding bucket 1. Several horizontal pipes 6 are vertically distributed between the side walls of the rectangular pipe 5, and vertical pipes 7 are horizontally distributed.

[0031] The height of the rectangular pipe 5 is 3 / 4 of the height of the bucket, ensuring that both the upper and lower layers of liquid food can come into contact with the heat source, and does not adhere to the inner wall of the food bucket 1, thus avoiding friction and wear;

[0032] The horizontal pipe 6 is set as a wavy pipe, and each layer of horizontal pipe 6 is sinusoidal in shape to increase the surface area of ​​the pipe. The diameter of different horizontal pipes 6 increases gradually from the upper layer to the lower layer. The vertical distribution density of the horizontal pipes 6 gradually increases from top to bottom. The spacing of the bottom layer of horizontal pipes 6 is denser to enhance the heat conduction of the thick liquid food at the bottom of the bucket.

[0033] The vertical pipe 7 is set as a tapered pipe, and its diameter increases linearly from top to bottom to increase the contact area between the liquid food and heat at the bottom of the feeding bucket 1. The distribution density of the vertical pipe 7 in the horizontal direction gradually increases from near the central axis of the feeding bucket 1 to away from the central axis to ensure that the liquid food at the edge is fully heated.

[0034] When the heat source is delivered from the cover plate 2 to the inside of the feeding bucket 1, the liquid food on the surface comes into contact with the heat first, while the liquid food at the bottom heats up slowly. Through the shape, diameter and density distribution of the horizontal pipe 6 and the vertical pipe 7, the heating area and density of the liquid food at the bottom are increased, thereby ensuring that the liquid food in the feeding bucket 1 is heated fully and evenly.

[0035] The rectangular pipe 5 is connected to a vertically upward-facing air supply pipe 8 on its sides. The top of the air supply pipe 8 is coaxially connected to the cover plate 2 and rotates. A servo motor is installed on the surface of the cover plate 2. The servo motor drives the air supply pipe 8 to rotate, which in turn drives the stirring pipe 4 to rotate, so that the stirring pipe 4 heats and stirs the liquid food at the same time, thus optimizing the effect of uniform heating.

[0036] For further details, please refer to Figure 1-2 The heating device is mounted on the cover plate 2 and is used to transfer heat to the air supply pipe 8. A sealing frame is fixed on the surface of the cover plate 2, and a servo motor is fixed on the surface of the sealing frame. A sealed chamber is formed between the sealing frame and the surface of the cover plate 2. A resistance wire heating hot air furnace is installed inside the chamber. The built-in temperature sensor achieves constant temperature control of 30-45℃ through a PID controller. The top of the air supply pipe 8 extends into the interior of the heating device, and several air supply holes 9 are evenly opened at one end of the air supply pipe 8 located in the inner cavity of the heating device to introduce hot air into the stirring pipe 4 to quickly raise the pipe wall temperature.

[0037] For further details, please refer to Figure 4A spiral plate 10 is coaxially fixed to the inner wall of the stirring pipe 4. The spiral plate 10 changes with the inner wall contour of the wavy horizontal pipe 6 and the conical vertical pipe 7. The spiral plate 10 changes the flow pattern of hot air in the pipe, increases the airflow path length, and the spiral structure breaks the straight flow, ensuring that the hot air fully contacts the entire pipe wall. The spiral angle of the spiral plate 10 is 15°-30°, which makes the hot air generate secondary circulation, balancing the flow resistance and heat exchange performance.
