Description

Technical Field

[0001] The utility model belongs to medical devices, and particularly relates to a drip-type liquid nasal feeding device for clinical nursing. Background Art

[0002] Nasogastric feeding is a medical method mainly used to provide nutrition or drugs for patients. Especially when patients are unable to eat by themselves or need special diet management, a catheter is inserted through the nasal cavity into the stomach or jejunum, and food, water, and drugs are infused through the tube to maintain the nutritional treatment of the patient.

[0003] Currently, during nasogastric feeding, after the solid and liquid components in food or nutrient solution are mixed, under the action of factors such as gravity, particle size, and density, the solid components in the container containing the liquid will gradually precipitate at the bottom of the container, while the liquid part floats on the upper part of the container. A series of problems will occur in the solid-liquid separation of the liquid. For example, the solid and liquid parts in the liquid usually contain different nutritional components. In the case of solid-liquid separation, patients may not obtain balanced nutrition, thus affecting their recovery and health; if the solid particles in the liquid are too large or too many, it may lead to an unsmooth feeding process and even blockage of the flow channel.

[0004] In response to the above problems, the Chinese utility model patent with the application number 2023215136653 discloses a nasal feeding device with controllable nasal feeding flow rate, which discloses that a servo motor is installed on the left side of the liquid bottle, and a stirring component is installed on the right side of the servo motor through an output shaft. The stirring component is placed in the liquid bottle, and the liquid in the liquid bottle is stirred by the stirring component to make the solid and liquid uniform. However, it is difficult for the stirring area of this stirring component to cover the bottom of the bottle. When the solid-liquid uniform liquid is at the bottom, a certain degree of solid-liquid separation will inevitably occur, resulting in an unsatisfactory uniformity of the outflowing liquid. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the problem of the uniformity of the liquid in the existing liquid nasal feeding device, and provide a drip-type liquid nasal feeding device that can stir the bottom of the liquid container and effectively improve the uniformity of the outflowing liquid.

[0006] The technical solution adopted by the utility model to solve its technical problems: The drip-type liquid nasal feeding device includes a non-metallic liquid container and a connecting tube. A liquid outlet is provided at the bottom of the liquid container, and the liquid outlet is communicated with the connecting tube. Several magnetic stirring components are provided on the outer bottom of the liquid container, and the magnetic stirring components are distributed around the liquid outlet. The stirring rotor of the magnetic stirring component is located on the inner bottom of the liquid container and is movably connected to the inner bottom of the liquid container. Stirring blades are provided on the stirring rotor, and the magnetic stirring component is connected to a controller through a wire.

[0007] Optionally, a hook is provided on the liquid container.

[0008] Optionally, a flow regulator is provided on the connecting pipe.

[0009] Optionally, a heating pipe group is connected in series on the connecting pipe. The heating pipe group mainly consists of a heating pipe, an induction coil sleeved outside the middle section of the heating pipe, and a housing covering the induction coil. The heating pipe group is connected to the controller through a wire. A temperature sensor with a screen display is provided on the outer wall of the fluid container, and the temperature probe of the temperature sensor is fixed in the inner cavity of the lower section of the heating pipe.

[0010] The usage method and principle of the present utility model: During use, the connecting pipe is blocked by the flow controller. The fluid is filled in the fluid container, and the fluid container is suspended by using the hook. The connecting pipe is connected to the gastric tube, and the gastric tube is inserted into the stomach through the nasal cavity. The magnetic stirring assembly is started through the controller. The motor of the magnetic stirring assembly drives the permanent magnet of the magnetic stirring assembly to rotate. The permanent magnet of the stirring assembly uses its magnetic force to attract the stirring rotor to rotate. The stirring rotor drives the stirring blades thereon to rotate. The stirring rotor continuously rotates, and the fluid at the bottom of the fluid container is stirred for a long time through the stirring blades, so that the fluid flowing out from the fluid outlet is uniform. The flow regulator is opened, and under the action of gravity, the uniform fluid slowly enters the gastric tube through the connecting pipe and then enters the patient's stomach in the form of drops through the gastric tube, thus automatically completing nasal feeding and liberating the hands of the nursing staff;

[0011] Regarding the temperature of the fluid, a heating pipe group is connected in series on the connecting pipe. The fluid enters the heating pipe of the heating pipe group through the connecting pipe. The heating pipe group is started through the controller, and the induction coil of the heating pipe group is energized. The temperature of the heating pipe is increased by using electromagnetic induction. The inner wall of the heating pipe contacts the fluid and heats the fluid. A temperature probe of the temperature sensor is provided at the lower section of the heating pipe of the heating pipe group, which can sense the fluid after heating. According to the detected temperature, the heating amount of the heating pipe group is adjusted through the controller to provide the fluid at a suitable temperature for the patient.

[0012] Compared with the prior art, the beneficial effects of the present utility model: The present utility model can stir the bottom of the fluid container, effectively improve the uniformity of the flowing-out fluid, and can heat the fluid to provide the fluid at a suitable temperature for the patient.
