TECHNICAL FIELD

[0001] The present application relates to the technical field of enteral nutrition infusion, in particular to an enteral nutrition infusion device with adjustable nutrient proportion. BACKGROUND

[0002] The enteral nutrition infusion is usually performed by means of a nasogastric tube, and a semi-recumbent position is adopted. After the infusion tube is connected to the bottle mouth of a Peptamen or other enteral nutrition liquid, it is connected to an infusion pump and then connected to the nasogastric tube of the patient for infusion. However, the concentration of the nutrition liquid needs to be gradually adjusted from low to high during the process to avoid gastrointestinal discomfort of the patient. However, the set speed of the infusion pump needs to be adjusted at regular intervals, and the concentration of the nutrient proportion can only be manually adjusted, which occupies a long time of the medical staff and makes it difficult to automatically adjust the concentration of the nutrient proportion. The temperature needs to be controlled at about 37-40 degrees to ensure that the patient's gastrointestinal tract is not stimulated. However, the existing infusion pump is difficult to heat, and the temperature is difficult to automatically adjust. SUMMARY

[0003] Therefore, the present application provides an enteral nutrition infusion device with adjustable nutrient proportion. When the syringe is completed by the infusion pump quantitative and timing delivery, gradually push the screw rod to move, drive the gear to rotate through the rack plate, and rotate the indicator plate until the touch switch is started. The baffle blocks the inside of the mixing pipe, automatically stops the infusion pump on the syringe, stops the delivery of the liquid except the nutrition liquid, realizes the full proportion infusion of the nutrition liquid, and automatically realizes the adjustment of the nutrient proportion.

[0004] The present application provides an enteral nutrition infusion device with adjustable nutrient proportion, which has the purposes and effects, and specifically includes: an infusion tube; a liquid outlet pipe fixedly connected to the bottom of the infusion tube; a mixing pipe connected to the right end of the infusion tube; a temperature control device sleeved outside the liquid outlet pipe; an electric control seat installed on the top of the mixing pipe; a proportion adjusting assembly installed inside the mixing pipe; the proportion adjusting assembly includes a baffle and a connecting plate, a round rod is fixedly arranged on the top of the baffle, the round rod penetrates and is sealingly connected in the mixing pipe, and two internally threaded pipes are arranged at the end of the connecting plate; and a threaded rod is threadedly connected inside the internally threaded pipe.

[0005] Further, a rod is fixedly connected to the bottom surface of the connecting plate, the end of the rod is fixedly and perpendicularly connected with a rack plate, the rack plate is movably connected inside the mixing pipe, and the rack plate is meshingly connected with a gear.

[0006] Furthermore, the temperature control device includes a snap-fit ​​half-tube, a temperature control module, and an insulation tube. A heating element is installed inside the snap-fit ​​half-tube, and a heat-conducting plate is welded to the inner wall of the heating element. The heat-conducting plate penetrates the inner wall of the snap-fit ​​half-tube and is attached to the outer wall of the outlet tube. The end face of the first snap-fit ​​half-tube has a rod and a hole. The position of the rod and hole of the second snap-fit ​​half-tube corresponds to that of the first. A power switch and a temperature adjustment button are installed on the top surface of the temperature control module, and the power switch and temperature adjustment button are electrically connected to a controller inside the temperature control module. A temperature sensing element is connected inside the temperature control module via a circuit. The temperature sensing element is attached to the outer wall of the outlet tube and installed inside the insulation tube, which is fitted over the outside of the outlet tube.

[0007] Furthermore, a screwing block is fixedly connected to the outer end of the threaded rod, and the outer end face of the screwing block is lower than the circular plate at the end of the syringe inner push rod.

[0008] Furthermore, the outer edge of the baffle is attached to the inner wall of the mixing tube, a gear is fixedly connected to the top round rod of the baffle, and an indicator plate is fixedly connected above the gear and at the top of the round rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] During use, after the syringe completes the quantitative and timed delivery through the infusion pump, it gradually pushes the threaded rod to move, which in turn moves the connecting plate. The rack plate can drive the gear to rotate, and the gear can coaxially drive the indicator plate to indicate the rotation angle. The indicator plate gradually approaches until the touch switch is activated, so that the baffle seals the inside of the mixing tube. This automatically stops the infusion pump on the syringe, stopping the delivery of liquids other than nutrient solutions such as Bifidobacterium infantis, thus achieving full-proportion infusion of nutrient solutions and automatically adjusting the nutrient ratio.

[0013] In addition, the two snap-fit ​​half-tubes can be assembled by interlocking the plug rods and sockets. The temperature control device is installed on the outside of the outlet tube. The heating element starts heating after the temperature control device is activated. The heat conduction plate heats the nutrient solution inside the outlet tube, ensuring that the temperature is suitable when it is delivered to the patient's nasogastric tube, so as not to irritate the stomach and cause discomfort. The temperature can be automatically adjusted after the temperature is preset by the controller inside the temperature control device.

[0014] In addition, the snap ring can increase the connection stability of the connecting pipe, ensure that no leakage occurs during injection, and by designing different sizes of the connecting pipe, the device can be connected to injectors of different capacities, improving the applicability of the device.
