Description

Technical Field

[0001] The present invention relates to the technical field of enteral nutrition delivery, and more specifically to an enteral nutrition agent delivery device for postoperative rehabilitation of critically ill patients. Background Art

[0002] Enteral nutrition (EN) is a method of directly delivering nutrient solutions to the gastrointestinal tract through oral or tube feeding routes, and is suitable for patients who are unable to eat orally but have partial or intact gastrointestinal functions. Postoperative critically ill patients are often in a state of hypermetabolism and hypercatabolism, and nutritional support is one of the key factors affecting recovery. Enteral nutrition (EN) has significant advantages over parenteral nutrition (PN) in promoting postoperative recovery, reducing complications, and improving clinical outcomes. Clinically, delivery devices such as the existing technologies CN114831893B and CN114948741A are mostly used to deliver enteral nutrition agents to critically ill patients to maintain the intestinal function of the patients, improve the prognosis, and promote recovery.

[0003] It is known that enteral nutrition agents are special medical formula foods designed for patients who are unable to eat orally normally but have remaining gastrointestinal functions. According to dosage form classification, there are powders (which need to be brewed during use), liquid agents, and thickening agents. All types of enteral nutrition agents have a certain viscosity, which inevitably leads to the situation that some enteral nutrition agents adhere to the inner wall of the delivery pipeline during the delivery process. After too much enteral nutrition agent adheres, it is very easy to cause pipeline blockage. Therefore, when the existing delivery devices are in use, they also need to be equipped with flushing devices such as the existing technologies CN119346556A, CN113102399B, and CN113083813B to flush the enteral nutrition agent delivery pipeline. Currently, the following problems have also been found in the existing enteral nutrition agent delivery devices and flushing devices after clinical use:

[0004] First, enteral nutrition agents may easily precipitate due to some insoluble components (such as dietary fiber), fat emulsions, or protein aggregation. The aggregation of these precipitates easily blocks the pipeline and affects the normal delivery of the nutrition agent;

[0005] Second, during the flushing process, not only do medical staff need to manually connect the enteral nutrition agent delivery tube and the flushing tube, which increases the workload of medical staff;

[0006] Third, all the flushing fluids generated during the flushing process will directly flow into the patient's body. Since the length of the nutrition agent delivery tube is relatively long, a large amount of flushing fluid will be generated when flushing this part of the pipeline. If this part of the flushing fluid directly enters the patient's stomach or intestine, it is very easy to cause gastrointestinal distension in the patient and cause discomfort. Summary of the Invention

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides an enteral nutrient delivery device for the postoperative rehabilitation of critically ill patients. By means of a heat-conducting shell A and a nutrient bottle shaking assembly, the nutrient bottle is driven to shake during the heating process to prevent precipitation aggregation. By setting up a branch pipe and a pipe clamp, the automatic switching between tube flushing and nutrient delivery is realized, simplifying the tube flushing operation, so as to solve the problems appearing in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: An enteral nutrient delivery device for the postoperative rehabilitation of critically ill patients, including a mobile rack. A nutrient pump for pumping nutrients is placed in the middle layer of the mobile rack. A delivery tube is clamped inside the nutrient pump. The bottom end of the delivery tube is connected to a gastrointestinal intubation tube inserted into the patient's body. The top end of the delivery tube is connected to a nutrient bottle, and the nutrients in the nutrient bottle directly enter the patient's body through the delivery tube and the gastrointestinal intubation tube.

[0009] Branch pipe assemblies are connected to both the top end and the bottom end of the delivery tube. The branch pipe assembly includes branch pipe a connected to the top end and branch pipe b connected to the bottom end. Under the pumping of the nutrient pump, the flushing liquid enters the delivery tube through branch pipe a for tube flushing and then is discharged through branch pipe b.

[0010] A heating base for heating the nutrient and the flushing liquid is provided on the top layer of the mobile rack. The heating base includes a nutrient bottle shaking assembly for driving the nutrient bottle to shake, which is used to shake the nutrient bottle in four directions of front, back, left and right in turn while heating.

[0011] In a preferred embodiment, the heating base further includes a heat-conducting shell A and a heat-conducting shell B. The heat-conducting shell A is sleeved at the bottom end of the nutrient bottle, and the heat-conducting shell B is sleeved at the bottom end of the flushing liquid bottle. The interiors of the heat-conducting shell A and the heat-conducting shell B are both hollow-shaped. Heat-conducting liquids are filled in the inner cavities of the heat-conducting shell A and the heat-conducting shell B. A plurality of electric heating rods for heating the heat-conducting liquids are installed in the inner cavities of the heat-conducting shell A and the heat-conducting shell B. The top ends of the electric heating rods extend out from the top of the heat-conducting shell A, and the heated heat-conducting liquids heat the nutrient and the flushing liquid through the outer walls of the heat-conducting shell A and the heat-conducting shell B.

[0012] Four springs a are fixed to the outer wall of the heat-conducting shell A. One end of one spring a is fixed to the outer wall of the heat-conducting shell B, and one end of the remaining three springs a is fixedly connected to a spring fixing seat. The nutrient bottle shaking assembly is located directly above the heat-conducting shell A.

[0013] In a preferred embodiment, the nutrient bottle shaking assembly includes a rubber suction cup adsorbed on the top of the nutrient bottle. A telescopic rod is fixed to the top end of the rubber suction cup, and a ball head is fixed to the top end of the telescopic rod. Four bent rods are fixedly connected to the outer wall of the ball head. The positions of the four bent rods correspond to those of four spring a up and down. A rotating wheel is rotatably connected to one end of each bent rod away from the ball head. A cam is provided on one side of the rotating wheel. A gear drive mechanism for driving the cam to rotate is provided at the bottom of the cam. The gear drive mechanism drives the four cams to rotate one full circle in sequence. The cam after rotating half a circle contacts the outer wall of the rotating wheel and pushes the rotating wheel to drive the ball head and the nutrient bottle at its bottom end to tilt to one side. The cam after rotating another half a circle does not contact the rotating wheel. At this time, the tilted nutrient bottle is pulled back to its original position by spring a. This reciprocating motion realizes the effect of shaking the nutrient bottle.

[0014] In a preferred embodiment, the drive mechanism includes a rotating shaft passing through each cam. A gear a is fixed to the bottom end of each rotating shaft. The gear a is externally engaged with an incomplete toothed ring a;

[0015] A complete toothed ring b is fixed to the bottom end of the toothed ring a. A gear b for driving the toothed ring b to rotate is engaged on one side of the toothed ring b.

[0016] In a preferred embodiment, an infusion box is fixed to the top layer of the mobile rack. The infusion box includes a box body fixed to the top of the mobile rack. A heat conduction shell B is fixed to one side inside the box body. A heat conduction shell A is located on the other side inside the box body. The top end of the rotating shaft is movably connected to the top end inside the box body through a bearing. The outer wall of the toothed ring a is movably connected to the inner wall of the box body through a slide rail. The gear b is rotatably connected inside the box body;

[0017] A box door is movably connected to the front side of the box body through a hinge. A control panel for controlling the rotation of the gear b and starting the electric heating rod is installed on the front side of the box door.

[0018] In a preferred embodiment, an infrared temperature sensor is provided on each side inside the box body. The two infrared temperature sensors are respectively used to monitor the temperatures of the heat conduction liquid inside the heat conduction shell A and the heat conduction liquid inside the heat conduction shell B and upload the temperature monitoring results to the control panel.

[0019] In a preferred embodiment, a needle for inserting into the flushing liquid bottle is fixed to the top end of the branch pipe a. Pipeline clamps for blocking the liquid flow can be detachably connected to the outer end of the branch pipe a, the outer end of the branch pipe b, the top end of the delivery pipe, and the bottom end of the delivery pipe;

[0020] The pipe clamp includes two pipe clamp housings distributed mirror-symmetrically. On one side of the two pipe clamp housings close to each other, semi-circular holes for the pipe to pass through are provided. An electromagnet is embedded in one inner side wall of the pipe clamp housing. A iron plate is provided on one side of the electromagnet. An arched pressing plate is fixed on one side of the iron plate. Compressed spring b is fixed at both ends of the pressing plate. The end of the spring b away from the pressing plate is fixed to the inner wall of the pipe clamp housing. After the electromagnet is powered on, it magnetically attracts the iron plate to fix the pressing plate outside the pipe. After the electromagnet is powered off, the compressed spring b pushes the pressing plate to squeeze the pipe to block the liquid flow.

[0021] In a preferred embodiment, ear plates are fixed on one side of the two pipe clamp housings close to each other. The two ear plates are detachably fixed together by bolts. The detachable setting can facilitate the removal of the pipe clamp from the pipe for repeated use and improve the utilization rate.

[0022] In a preferred embodiment, a flushing liquid bag for collecting flushing liquid is connected to one end of branch pipe b, which is used to separately collect the flushing liquid after flushing the conveying pipe.

[0023] The technical effects and advantages of the present invention:

[0024] 1. The present invention uses the heat-conducting shell A to thermostatically heat the nutrient agent inside the nutrient agent bottle to avoid cold stimulation to the human body when the nutrient agent enters the patient's body. At the same time, the nutrient agent bottle shaking assembly is used to drive the nutrient agent bottle to shake in four directions of front, back, left, and right in turn while heating to prevent precipitation aggregation and reduce the probability of pipeline blockage, which is beneficial to ensuring the smooth progress of the nutrient agent infusion process.

[0025] 2. The present invention adds branch pipe a and branch pipe b to the conveying pipe. The flushing liquid is conveyed into the conveying pipe through branch pipe a for pipe flushing. The flushing liquid after pipe flushing flows into the flushing liquid bag through branch pipe b. This part of the cleaning liquid will not directly enter the patient's body, which is beneficial to reducing the volume of the flushing liquid entering the patient's body to avoid discomfort in the patient's gastrointestinal tract.

[0026] 3. The present invention directly connects the top end of branch pipe a to the flushing liquid bottle filled with flushing liquid, so that the nutrient pump can also inhale hot water into the conveying pipe when the nutrient agent pumping is paused, realizing the free switching between "pipe flushing" and "nutrient agent conveying". This pipe flushing operation can be carried out at any time without manual connection by medical staff, simplifying the operation steps and enhancing the convenience. Description of the Drawings

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Referring to the attached Figure 1-3 description, the present invention provides an enteral nutrient delivery device for postoperative rehabilitation of critically ill patients, including a mobile rack 1. The shape of the mobile rack 1 is as Figure 10 shown, which includes three layers arranged in sequence from top to bottom. Among them, a nutrient pump 2 for pumping nutrients is placed in the middle layer of the mobile rack 1. The nutrient pump is a medical device for precisely controlling the infusion speed and dose of enteral nutrient solution (EN, Enteral Nutrition), and is mainly used for patients who cannot eat orally but have normal gastrointestinal functions;

[0046] An infusion box 3 is fixed on the top layer of the mobile rack 1. The infusion box 3 includes a box body 31 fixed on the top of the mobile rack 1. The front side of the box body 31 is movably connected with a box door 32 through a hinge. A control panel 33 is fixed on the front side of the box door 32. Mobile wheels are also fixed at the bottom of the mobile rack 1, which can facilitate medical staff to push the present invention for movement and achieve use-on-demand access.

[0047] A delivery tube 4 is clamped inside the nutrient pump 2. The bottom end of the delivery tube 4 is connected to a gastrointestinal intubation 5 inserted into the patient's body. The top end of the delivery tube 4 is connected to a nutrient agent bottle. Under the pumping action of the nutrient pump 2, the nutrient agent in the nutrient agent bottle can be directly delivered into the patient's body through the delivery tube 4 and the gastrointestinal intubation 5 to achieve enteral nutrition supply.

[0048] Since the nutrient agent itself has a certain viscosity, it is inevitable that the inner wall of the delivery tube 4 for transporting nutrients will have the problem of nutrient agent adhesion. Clinically, the method of "flushing the tube" is often used to wash away the nutrient agent adhered inside the delivery tube 4. In the present invention, branch pipe assemblies 7 are connected to both the top end and the bottom end of the delivery tube 4, such as Figure 4 , Figure 5 and Figure 7As shown: The structure of the branch pipe assembly 7 includes a branch pipe a71 connected to the top end of 41 and a branch pipe b72 connected to the bottom end of 41. At the top end of the branch pipe a71, a needle for inserting into the flushing solution bottle is fixed. One end of the branch pipe b72 is connected to a flushing solution bag 8 for collecting the flushing solution. It is also possible to order the flushing solution to enter the delivery pipe 4 through the branch pipe a71 for pipe flushing under the pumping of the nutrient pump 2, and then be discharged through the branch pipe b72 and finally flow into the flushing solution bag 8 for collection. This design can not only solve the problem of pipeline blockage, but also separately collect the flushing solution after flushing the delivery pipe 4, avoiding the discomfort of the patient's gastrointestinal part caused by the direct flow of this part of the flushing solution into the patient's body, and helping to reduce the burden on the patient's gastrointestinal part;

[0049] Pipeline clamps 9 for blocking the flow of liquid are detachably connected to the outer end of the branch pipe a71, the outer end of the branch pipe b72, the top end of the delivery pipe 4, and the bottom end of the delivery pipe 4. Specifically, as Figure 8 and 9 shown: The pipeline clamp 9 includes two mirror-distributed pipeline clamp housings 91. On one side of the two pipeline clamp housings 91 that are close to each other, ear plates 92 are fixed. The two ear plates 92 are detachably fixed together by bolts. The detachable setting can facilitate the removal of the pipeline clamp 9 from the pipeline for repeated use and improve the utilization rate;

[0050] On one side of the two pipeline clamp housings 91 that are close to each other, semi-circular holes 97 for the pipeline to pass through are provided. Inside one side wall of the pipeline clamp housing 91, an electromagnet 93 is embedded. On one side of the electromagnet 93, there is an iron plate 95. On one side of the iron plate 95, an arched pressing plate 94 is fixed. At both ends of the pressing plate 94, compressed springs b96 are fixed. The ends of the springs b96 away from the pressing plate 94 are fixed to the inner wall of the pipeline clamp housing 91. During use, reference can be made to Figure 7 the position of the pipeline clamp 9 in Figure 9 for its installation. By covering the two pipeline clamp housings 91 outside the pipeline and tightening the bolts on the ear plates 92 to fix the position of the pipeline clamp 9, at this time, the electromagnet 93 is in the energized state. After being energized, the electromagnet 93 will magnetically attract the iron plate 95 to fix the pressing plate 94 outside the pipeline, as shown in

[0051] The nutrition pump 2 in the present invention can not only be used to pump nutritional agents, but also to pump flushing fluid for tube flushing. It serves multiple purposes, significantly improving the utilization efficiency of existing medical devices and reducing treatment costs. At the same time, the energization and de-energization of the electromagnet 93 in the pipe clamp 9 are both controlled by the control panel 33 on the front side of the cabinet door 32. Through the control program in the control panel 33, the tube flushing operation can be automatically performed every 4 - 6 hours. During the tube flushing operation, the control panel 33 automatically controls the electromagnet 93 at the outer end of the delivery tube 4 to be de-energized, and automatically controls the electromagnets 93 at the outer ends of the branch pipe a71 and the branch pipe b72 to be energized, so as to block the flow of nutritional agents and allow the flow of cleaning fluid, realizing the automatic switching between "tube flushing" and "nutritional agent delivery".

[0052] In addition, if a large amount of nutritional agents also adhere to the inside of the gastrointestinal intubation 5, after the inside of the delivery tube 4 is rinsed clean, the control panel 33 can also automatically control the electromagnet 93 at the bottom end of the delivery tube 4 to be energized and the electromagnet 93 at the outer end of the branch pipe b72 to be de-energized, so that the flushing fluid flowing in the delivery tube 4 can enter the inside of the gastrointestinal intubation 5 for tube flushing. Moreover, the length of the gastrointestinal intubation 5 is much smaller than the length of the delivery tube 4, and the volume of the flushing fluid in this part of the pipeline is not too much. Therefore, even if this part of the flushing fluid enters the patient's body, it will not significantly cause discomfort to the patient.

[0053] During the above process of nutritional agent delivery and tube flushing, to prevent the temperature of the nutritional agent and the flushing fluid entering the patient's body from being lower than the human body temperature and causing cold stimulation to the patient's stomach, as Figure 3 shown, a heating base 6 for heating nutritional agents and flushing fluid is provided on the top layer of the moving frame 1. Specifically, as Figure 4 and Figure 5 shown, the structure of the heating base 6 includes a heat-conducting shell A61 and a heat-conducting shell B62. The heat-conducting shell B62 is fixed on one side inside the box body 31, and the heat-conducting shell A61 is located on the other side inside the box body 31. The bottom of the heat-conducting shell A61 is in contact with the inner wall of the box body 31 to facilitate its shaking. The heat-conducting shell A61 is sleeved at the bottom end of the nutritional agent bottle, and the heat-conducting shell B62 is sleeved at the bottom end of the flushing fluid bottle. The inside of the heat-conducting shell A61 and the inside of the heat-conducting shell B62 are both set to be hollow. Heat-conducting liquid is filled in the inner cavity of the heat-conducting shell A61 and the inner cavity of the heat-conducting shell B62. In this embodiment, the heat-conducting liquid is preferably water. A plurality of electric heating rods 63 for heating the heat-conducting liquid are installed in the inner cavity of the heat-conducting shell A61 and the inner cavity of the heat-conducting shell B62. The top ends of the electric heating rods 63 extend out from the top of the heat-conducting shell A61. By starting the electric heating rods 63, the heat-conducting liquid inside the heat-conducting shell A61 and the heat-conducting shell B62 can be heated, as Figure 4 and Figure 5The nutrient bottle shown in the figure is in contact with the inner wall of the heat-conducting shell A61, and the rinsing liquid bottle is in contact with the inner wall of the heat-conducting shell B62. Therefore, the heated heat-conducting liquid can heat the nutrient and the rinsing liquid through the outer walls of the heat-conducting shell A61 and the heat-conducting shell B62 respectively, so as to ensure that the temperatures of the nutrient and the rinsing liquid entering the human body are consistent with the human body temperature, and avoid irritating the patient's stomach and intestines;

[0054] An infrared temperature sensor 66 is also provided on each side inside the box body 31. The two infrared temperature sensors 66 are respectively used to monitor the temperatures of the heat-conducting liquid inside the heat-conducting shell A61 and the heat-conducting shell B62 and upload the temperature monitoring results to the control panel 33 in real time. Under the action of the real-time temperature measurement of the infrared temperature sensor 66, the control panel 33 can conveniently and accurately control the heating temperature of the electric heating rod 63, ensuring that the temperatures of the heat-conducting liquid inside the heat-conducting shell A61 and the heat-conducting shell B62 are slightly higher than the real-time body temperature of the patient, and the maximum temperature difference is not greater than 5 °C, so as to make up for the heat loss during the heat conduction process, and make the temperature of the heated rinsing liquid in the rinsing liquid bottle and the temperature of the heated nutrient in the nutrient bottle consistent with the patient's body temperature.

[0055] In this embodiment, a nutrient bottle shaking assembly 67 for driving the nutrient bottle to shake is also provided on the top of the heat-conducting shell A61. Four springs a64 are fixed on the outer wall of the heat-conducting shell A61. One end of one spring a64 is fixed to the outer wall of the heat-conducting shell B62, and the other ends of the remaining three springs a64 are all fixedly connected with spring fixing seats 65, which are used to shake the nutrient bottle in the front, back, left and right directions in turn while heating, so as to prevent the precipitation in the nutrient from aggregating and causing pipeline blockage. Specifically, as shown in Figure 6 the figure: The nutrient bottle shaking assembly 67 includes a rubber suction cup 671 adsorbed on the top of the nutrient bottle. The top of the rubber suction cup 671 is fixed with a telescopic rod 672. The top of the telescopic rod 672 is fixed with a ball head 673. Four bent rods 674 are fixed on the outer wall of the ball head 673. The four bent rods 674 correspond to the positions of the four springs a64 up and down. One end of each bent rod 674 away from the ball head 673 is rotatably connected with a rotating wheel 675. A cam 676 is provided on one side of the rotating wheel 675. A gear driving mechanism for driving the cam 676 to rotate is provided at the bottom of the cam 676. Further, the driving mechanism includes a rotating shaft 677 passing through each cam 676. The top of the rotating shaft 677 is movably connected to the top inside the box body 31 through a bearing. A gear a678 is fixed at the bottom end of each rotating shaft 677. The gear a678 is externally meshed with an incomplete toothed ring a679. The outer wall of the toothed ring a679 is movably connected to the inner wall of the box body 31 through a slide rail. A complete toothed ring b6710 is fixed at the bottom end of the toothed ring a679. A gear b6711 for driving the toothed ring b6710 to rotate is meshed on one side of the toothed ring b6710. The gear b6711 is driven to rotate by a motor;

[0056] Before the nutrient agent is delivered, the nutrient agent bottle containing the nutrient agent needs to be placed in the heat conduction shell A61 first. Then, the telescopic rod 672 is pulled downward so that the rubber suction cup 671 at the bottom end of the telescopic rod 672 can firmly adsorb on the top end of the nutrient agent bottle. Then, the length of the telescopic rod is fixed by bolts, as Figure 4 and Figure 5 shown. At this time, the ball head 673 is fixed to the nutrient agent bottle through the rubber suction cup 671;

[0057] Then, the nutrient agent is delivered. During this process, the control panel 33 controls the motor to drive the gear b6711 to rotate. The rotating gear b6711 drives the meshing ring gear b6710 to rotate. Since the ring gear b6710 is fixed to the ring gear a679, the rotating ring gear b6710 can drive the ring gear a679 to rotate synchronously. And the ring gear a679 is an incomplete ring gear. Each time the teeth inside it mesh with a gear a678, it can drive the gear a678 to rotate a full circle. The rotation of the ring gear a679 can drive the four gears a678 to rotate in turn. After rotating half a circle, the gear a678 drives the cam 676 to rotate half a circle synchronously. At this time, the cam 676 contacts the outer wall of the rotating wheel 675 and pushes the rotating wheel 675 to drive the ball head 673 and the nutrient agent bottle at its bottom end to tilt away from the cam 676. At the same time, the spring a64 located directly below it is pulled by the heat conduction shell A61 to elongate;

[0058] Next, after the gear a678 continues to rotate half a circle, the cam 676 no longer contacts the rotating wheel 675. At this time, the stretched spring a64 will pull the tilted heat conduction shell A61 to drive the nutrient agent bottle to return to the vertical position. Repeating this process can achieve the effect of shaking the nutrient agent bottle back and forth and left and right, and then can shake the nutrient agent inside the nutrient bottle to prevent precipitation aggregation and ensure the smooth progress of the intestinal delivery process of the nutrient agent.

[0059] Finally: The above is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
