[0029] The utility model will be explained in further detail in combination with the drawings. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the structure related to the utility model, and the direction and reference (such as up, down, left, right, etc.) can be only used to help the description of the features in the drawings. Therefore, the following specific embodiments are not in the restrictive sense, and the scope of the claimed subject matter is only limited by the appended claims and their equivalents.

[0030] As shown in Figure 1 and Figure 2 , a nutrient solution storage container is connected with an infusion mechanism 3, and the infusion mechanism 3 can deliver the nutrient solution in the storage container to the patient's body, and the storage container comprises:

[0031] a liquid storage body 1 having a liquid storage cavity and a filling port 101 communicating with the liquid storage cavity, and the filling port 101 can add nutrient solution or flushing solution to the liquid storage cavity;

[0032] and a cover 2 having a first connecting port 201 and a second connecting port 202 penetrating each other, the first connecting port 201 is detachably connected with the filling port 101, the second connecting port 202 is detachably connected with the infusion mechanism 3, and the caliber of the first connecting port 201 is larger than that of the second connecting port 202 to form a stepped structure with one end large and the other end small, and correspondingly, the caliber of the filling port 101 matched with the first connecting port 201 is also larger than that of the second connecting port 202, the second connecting port 202 with small caliber is used to match with the infusion mechanism 3, and the filling port 101 with large caliber facilitates the addition of nutrient solution or flushing solution, improving the portability and efficiency of nutrient solution deployment.

[0033] When the second connection port 202 is separated from the infusion mechanism 3, the liquid reservoir body 1 can be sealed by putting a protective cap on the second connection port 202, so that it can be used as a sub-packaging container for nutrient solution or flushing solution, which is convenient for storage or carrying.

[0034] When the second connecting port 202 is connected to the infusion mechanism 3, the liquid in the liquid storage chamber can enter the infusion mechanism 3 through the feeding port 101, the first connecting port 201 and the second connecting port 202 in sequence for nutrient infusion. At this time, the feeding port 101 also serves as the liquid outlet. If the infusion mechanism 3 is blocked during the process, the storage container can be separated from the infusion mechanism 3 and the infusion mechanism 3 can be replaced separately to avoid repeated preparation of the nutrient solution caused by the overall replacement of the storage container and the infusion mechanism 3. If the infusion mechanism 3 needs to be flushed, it can be quickly replaced with a storage container filled with flushing liquid, thereby simplifying the flushing procedure of the infusion mechanism 3.

[0035] In some examples, such as Figure 2 As shown, the liquid reservoir body 1 is a soft liquid storage bag, which is roughly rectangular.

[0036] In some examples, the liquid reservoir body 1 is a liquid storage bottle, which is generally cylindrical.

[0037] In some examples, the cover 2 is provided with a vent 203 between the first connection port 201 and the second connection port 202, which is connected to the atmosphere to allow the liquid in the liquid storage bottle to drip, thereby forming a three-way pipe structure of the cover 2. The first connection port 201 and the second connection port 202 are collinear. When the storage container is used as a separate packaging container, a plug is provided on the vent 203 to seal the storage container.

[0038] During nutrient infusion, the nutrient solution in the liquid storage cavity drips to the infusion mechanism 3 under the action of gravity. When the liquid reservoir body 1 is a liquid storage soft bag, the soft liquid storage bag gradually collapses while the nutrient solution is infused, and the volume of the liquid storage cavity gradually decreases to make the pressure inside and outside the liquid storage cavity equal, and the nutrient solution therein can gradually drip until the infusion is completed; when the liquid reservoir body 1 is a liquid storage bottle, the volume of the liquid storage cavity in the hard liquid storage bottle remains unchanged while the nutrient solution is infused, resulting in a decrease in its internal pressure. The pressure difference between the inside and outside of the liquid storage cavity prevents the nutrient solution from dripping, and the setting of the vent 203 can balance the pressure difference to allow the nutrient solution to drip.

[0039] In some examples, the liquid storage soft bag is provided with a hanging hole 102 for hanging the liquid storage soft bag. The number of the hanging holes 102 can be one, two, or three, etc., which is not limited in this embodiment. When the number of the hanging hole 102 is one, it can be located on the side of the liquid storage soft bag away from the liquid filling port for the liquid storage soft bag to be inverted. When the number of the hanging holes 102 is multiple, they can be distributed at intervals along the circumference of the liquid storage soft bag.

[0040] In some examples, the first connection port 201 is spirally connected to the feeding port 101 to form a screw-on design. The spiral structure can ensure the sealing between the two to avoid leakage. The feeding port 101 is provided with a male thread, and the first connection port 201 is provided with a female thread that cooperates with the male thread, and the outer peripheral wall of the first connection port 201 is provided with a plurality of anti-slip grooves 2011 arranged at intervals along its circumference. The external anti-slip grooves 2011 correspond to the positions of the internal female threads. The male threads and the female threads cooperate to realize the spiral connection between the storage container and the infusion mechanism 3. The anti-slip grooves 2011 on the first connection port 201 can facilitate the tightening and loosening of the threads; correspondingly, a female thread can also be provided on the feeding port 101, and a male thread can be provided on the first connection port 201. At this time, in order to avoid the male thread, the anti-slip grooves 2011 need to be arranged side by side with the male thread, which will lead to an increase in the size of the cover body 2. When the storage container is used as a packaging container, it will bring inconvenience in storage and carrying.

[0041] In some examples, the second connection port 202 is a threaded port that is screwed to the infusion mechanism 3 or a bayonet port that snaps into the infusion mechanism 3 to achieve a detachable connection between the storage container and the infusion mechanism 3. Preferably, the two are threaded to prevent disengagement, thereby ensuring continuous and stable infusion. As described above, the second connection port 202 is preferably provided with a male thread, and the infusion mechanism 3 is provided with male and female threads that mate with the male thread, and the outer peripheral wall thereof is provided with an anti-slip groove.

[0042] In some examples, a nutrition infusion device includes the above-mentioned storage container and an infusion mechanism 3 connected to the storage container.

[0043] In some examples, the infusion mechanism 3 is a syringe, which has an injection connector connected to the second connection port 202. After the injection connector is connected to the storage container, the syringe can absorb the nutrient solution in the storage chamber into the injection chamber, and then separate the injection connector from the storage container. The nutrient solution in the injection chamber can be injected into the patient's body through the syringe.

[0044] In some examples, such as Figure 3 and Figure 5 As shown, the infusion mechanism 3 is a hose 306 and a nutrient pump 307 for driving the flow of liquid in the hose 306. The nutrient pump 307 includes a pump housing 3071 and a pump cover 3072 rotatably mounted on the pump housing 3071. A roller 3073 is rotatably mounted on the pump housing 3071. Part of the hose 306 is wound around the outer circumference of the roller 3073. When the roller 3073 rotates, it can drive the liquid inside the hose 306 to flow for nutrient infusion. When the roller 3073 stops rotating, the liquid inside the hose 306 stops flowing.

[0045] One end of the hose 306 is provided with a liquid inlet connector 301 connected to the second connecting port 202, and the other end is provided with a liquid outlet connector 302 connected to a nasogastric tube or a nasointestinal tube to infuse nutrient solution into the patient's body, and the middle part of the hose 306 is provided with a drip pot 303, a dosing port and a flow regulator 305. The drip pot 303 can observe the infusion status and the drip flow rate, and the flow regulator 305 can adjust the infusion flow rate. The dosing mechanism 304 divides the hose 306 into a first tube body and a second tube body, and the dosing mechanism 304 includes a tee. The first branch and the second branch of the tee are respectively connected to the first tube body and the second tube body, and the third branch of the tee has a dosing port, which can be threadedly connected to the syringe to facilitate the addition or absorption of materials. The liquid medicine added from the dosing port can enter the patient's body alone or together with the nutrient solution in the liquid storage cavity.

[0046] Figure 4 This is a schematic diagram of the use of a liquid storage bag and a hose 306. After the second connecting port 202 of the liquid storage bag is spirally connected to the liquid inlet connector 301 of the hose, the liquid storage bag is inverted for nutrient infusion. When the infusion line is blocked, the second connecting port 202 can be disconnected from the liquid inlet connector 301, and the liquid storage bag filled with nutrient solution can be replaced with a similar liquid storage bag filled with flushing liquid to complete the flushing of the infusion line. After the flushing is completed, the liquid storage bag filled with nutrient solution can be replaced for nutrient infusion to ensure the continuity of the nutrient infusion process.
