Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nasogastric feeding nutrient solution delivery mechanism. Background Art

[0002] Nasogastric feeding is a technique in which a tube is inserted through the nasal cavity into the stomach, and food, water, and medication are infused into the patient's stomach through this tube. It is commonly used for patients who are unable to eat independently due to coma, oral diseases, oral surgery, esophageal stenosis, esophageal tracheal fistula, certain surgeries, or tumors. Common complications of nasogastric feeding include diarrhea, nausea, vomiting, hyperglycemia or hypoglycemia, dehydration, and aspiration. To reduce the occurrence of complications, the infusion rate and amount should be strictly controlled, the temperature of food and medication should be maintained at an appropriate level, and attention should be paid to the patient's position and comfort.

[0003] Bedridden patients use nasogastric feeding to input nutrients to maintain their lives. The temperature and flow rate of the nasogastric feeding need to be appropriate to allow patients to absorb nutrients more comfortably. If the flow rate is too fast, it will cause absorption difficulties, vomiting, etc. If the nasogastric feeding temperature is too low, it will cause diarrhea, etc., so a flow rate control and temperature control structure need to be set in the nasogastric feeding device. At the same time, since the nasogastric feeding flow rate is very slow, the pipeline from the nasogastric feeding bag to the patient's body is greatly affected by the ambient temperature. If the room temperature is low, even if the nasogastric feeding liquid is at the right temperature when it flows out of the nasogastric feeding bag, the temperature has dropped a lot when it enters the patient's body. Therefore, the existing nasogastric feeding heating device is usually placed in the nasogastric feeding bag. The temperature of the infusion pipeline is measured and heated at a certain position, and the existing heating devices are mostly clamp-shaped heating devices, which are installed on the infusion pipeline to heat the infusion pipeline according to the temperature measurement data. However, when used in winter, due to the low temperature in winter, the temperature of the nutrient solution in the infusion pipeline drops rapidly, and the nutrient solution usually contains starch, protein and other substances. Then, in the front part of the clamp-shaped heating device, the temperature of the nutrient solution is relatively low. The low temperature will increase the viscosity of the nutrient solution. If there is residue in the nutrient solution, it will easily cause the pipeline to be blocked. For this reason, we propose a nasogastric nutrient solution delivery mechanism. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-11The present invention provides a technical solution: a nasogastric nutrient solution delivery mechanism. The present invention makes corresponding improvements to the technical problems mentioned in the background technology, including a barrel 1 and an inner barrel 2 fixedly mounted on the barrel 1. In the present invention, the inner barrel 2 and the barrel 1 can be fixedly connected by bolts, so that the inner barrel 2 can be separated from the barrel 1, wherein the inner barrel 2 is used to hold nutrients, and a filter disc 21 for filtering nutrients is installed at the bottom of the inner barrel 2. The filter disc 21 can block the unbroken residues in the nutrients, and a pressure pump 3 is fixedly installed at the bottom of the barrel 1, and an infusion pipe 4 is connected between the bottom of the filter disc 21 and the pressure pump 3, and the end of the infusion pipe 4 passes through the inner wall of the barrel 1 and extends The infusion pipe 4 extends to the outside and is used to deliver nutrients to the patient's stomach. A temperature detection unit 41 and a flow rate detection unit 42 are also installed on the infusion pipe 4, and a heating pipe 5 is wrapped around the outer wall of the inner tube 2. The nutrients are heated by the heating pipe 5. It is further explained that the temperature detection unit 41 and the heating pipe 5 are communicated and connected. In the present invention, when the temperature detection unit 41 detects that the temperature of the nutrients here is lower than 38 degrees, the heating pipe 5 is controlled to heat; when the temperature detection unit 41 detects that the temperature of the nutrients here is higher than 38 degrees, the heating pipe 5 is controlled to stop heating. In cold seasons, nutrients are more easily affected by the ambient temperature when passing through the infusion pipe 4. The maximum heating temperature of the heating pipe 5 is 40°C. In actual use, the existing flow rate control is only achieved by squeezing the nutrient bag, and does not take into account the relative position relationship between the pressure pump 3 and the body, the effect of indoor temperature on liquid fluidity and other factors. Therefore, the flow rate needs to be controlled within a certain range. When the temperature is appropriate, that is, when the temperature does not need to be adjusted, the pressure pump 3 communicates with the flow rate detection unit 42 to control the pressure of the pressure pump 3 according to the flow rate. If the flow rate is slow, the pressure is increased; if the flow rate is too fast, the pressure is reduced. The inner cylinder 2 is also threadedly connected to a cover plate 22, and a servo motor 23 is fixedly mounted on the cover plate 22, and the output end of the servo motor 23 passes through the cover plate 22 and extends to the inner A detachable rotating shaft 24 is installed inside the cylinder 2 and on the output end of the servo motor 23. A plurality of stirring shafts 25 are installed on the rotating shaft 24. Each stirring shaft 25 is provided with a plurality of stirring parts 6. In order to facilitate the user to clean the inner cylinder 2, the user can pick up the cover plate 22 from the inner cylinder 2. Since the servo motor 23 is fixedly connected to the cover plate 22, and the output end of the servo motor 23 is detachably connected to the rotating shaft 24, after the cover plate 22 is removed, the user can remove the rotating shaft 24 from the output end of the servo motor 23, and then clean the stirring shaft 25 and the stirring part 6 on the rotating shaft 24. The inner cylinder 2 can also be disassembled for corresponding cleaning.

[0033] The stirring part 6 includes a rhombus block 61. A plurality of rhombus blocks 61 are arranged at intervals along the axial direction of the stirring shaft 25. Figure 3As shown, the diamond block 61 is tilted on the stirring shaft 25, and the angle difference α between each diamond block 61 and the stirring shaft 25 is in the range of 30°<α<60°, so that the diamond block 61 can better stir the nutrients and achieve a better stirring effect. Figure 4 As shown, the multiple diamond blocks 61 on the stirring shaft 25 rotate with the rotating shaft 24, and each diamond block 61 corresponds to each area of ​​the solution in the inner cylinder 2, and the two sides of the diamond block 61 are provided with multiple convection holes 62, and the multiple convection holes 62 on the two sides of the diamond block 61 correspond to each other, and a through hole 63 is opened at the end of the diamond block 61, and the through hole 63 is in a connected state with the convection hole 62, and a T-shaped flow channel is formed between each two corresponding convection holes 62 and the through hole 63 (as shown in FIG. Figure 6 As shown), a detachable annular sleeve 7 is provided on one side of each diamond block 61, and the annular sleeve 7 is fixedly connected to the stirring shaft body 25, wherein a spherical member 64 is installed at the end of the diamond block 61, and a spherical groove 71 adapted to the spherical member 64 is provided inside the annular sleeve 7, and the spherical member 64 rotates in the spherical groove 71;

[0034] Combined with attachment Figure 3 and attached Figure 4 As shown, when the nutrients are placed in the inner cylinder 2, the temperature detection unit 41 first detects the temperature of the nutrients in the infusion pipe 4. If the temperature is low, the nutrients can be heated through the heating pipe 5. During the heating process, in order to heat the nutrients in the inner cylinder 2 evenly and prevent them from becoming too viscous (nutrients usually contain high-protein, high-fat and other ingredients, which may become viscous during the heating process due to protein denaturation, fat melting and other reasons), the servo motor 23 is used to rotate the rotating shaft 24. During the rotation of the rotating shaft 24, the multiple stirring shafts 25 thereon rotate synchronously with it, and the diamond block 61 will be affected by the nutrients. Obstructive force; When the diamond block 61 rotates with the rotating shaft 24, the nutrients in the inner cylinder 2 will exert a force on the surface of the diamond block 61. If one of the side surfaces of the diamond block 61 is located in a relatively viscous area and the nutrients on the other side have a lower viscosity, the diamond block 61 will rotate under the action of the spherical member 64, thereby effectively increasing the stirring efficiency. In addition, during the rotation, the convection holes 62 on the surface of the diamond block 61 will enter the nutrients. It should be noted that when the diamond block 61 is not rotating, the convection holes 62 will also flow into the nutrients accordingly. The inner walls of the convection holes 62 and the through holes 63 need to be polished smooth to reduce the viscosity of the nutrients on the inner walls of the holes.

[0035] Combined with attachment Figure 5 and attached Figure 6As shown, the nutrients will enter the convection holes 62 or the through holes 63 during the flow process and flow in a direction along the flow path, thereby realizing the replacement of nutrients in each area. For the convenience of description, when the diamond block 61 performs a circular motion with the rotating shaft 24, the nutrients located on the movement trajectory of the diamond block 61 will enter the through holes 63. At this time, if the nutrients entering the through holes 63 are relatively viscous, they will flow through the trajectory of the convection holes 62 and enter the area corresponding to the end of the convection holes 62, thereby allowing the nutrients in the inner cylinder 2 to flow. On the one hand, it solves the problem of viscous heating of nutrients, and on the other hand, it improves the uniformity of nutrient heating.

[0036] It is inevitable that there will be food residues in the nutrients due to uneven crushing. The food residues will affect the patient's absorption of nutrients and easily cause blockage of the infusion pipe 4, affecting the smooth progress of nasogastric feeding. A circular sleeve 8 is fixedly installed at the end of the rotating shaft 24, and a processing frame 81 is connected to the circular sleeve 8, wherein an annular shaft 82 rotatably connected to the inner wall of the processing frame 81 is installed inside the processing frame 81, and one end of the annular shaft 82 passes through the inner wall of the processing frame 81 and extends to the inside of the circular sleeve 8. A plastic roller 83 is also provided inside the processing frame 81, and a plurality of telescopic parts 84 connected to the plastic roller 83 are installed on the annular shaft 82. The side wall of the processing frame 81 is provided with a plurality of filter holes 811 for hindering the flow of food residues. Figure 8 As shown, in this state, the telescopic portion 84 is in a contracted state, and the telescopic portion 84 includes a shaft, a sleeve and a spring installed inside (not shown). The plastic roller 83 is in contact with the side wall of the processing frame 81 under the squeezing action of the telescopic portion 84, and a sliding plate frame 85 is installed on the side wall of the processing frame 81 to be slidably connected to its outer wall. A plurality of combing shafts 851 corresponding to the filter holes 811 are fixedly installed on each sliding plate frame 85. A magnetic sleeve 86 is also fixedly installed on one end of the annular shaft 82 located inside the circular sleeve 8, and a return spring 87 is connected between the magnetic sleeve 86 and the inner wall of the circular sleeve 8, and an electromagnetic mechanism 88 is fixedly installed on the inner wall of the circular sleeve 8. When the electromagnetic mechanism 88 is energized, a repulsive force is generated on the magnetic sleeve 86. A spiral groove 89 is also provided on the inner wall of the circular sleeve 8, and a rolling ball 861 is installed on the magnetic sleeve 86, and the rolling ball 861 slides within the spiral groove 89.

[0037] During the rotation of the rotating shaft 24, the circular sleeve 8 rotates synchronously with it, and then the processing frame 81 connected to the circular sleeve 8 rotates synchronously, and then part of the food residue blocked by the filter plate 21 enters the processing frame 81. Figure 11As shown, the interior of the filter hole 811 is conical, so that food residues will enter the filter hole 811 and be blocked by the small aperture of the filter hole 811 and cannot flow out, thereby causing the food residues to be collected in the filter hole 811. In order to facilitate pushing the food residues on the side wall of the processing frame 81 into the filter hole 811, the electromagnetic mechanism 88 can be energized, and the electromagnetic mechanism 88 generates a repulsive force on the magnetic sleeve 86, so that the rolling ball 861 on the magnetic sleeve 86 will move along the trajectory of the spiral groove 89 and squeeze the return spring 87 at the same time. Then the annular shaft 82 will rotate, and during the rotation, the plastic roller 83 will push the food residue on the side wall of the processing frame 81 into the filter hole 811, thereby realizing the collection function. When the rotating shaft 24 leaves the inner cylinder 2, the processing frame 81 also leaves the inner cylinder 2 under the action of the circular sleeve 8, and the staff can clean the processing frame 81. The food residue blocked in the filter hole 811 can push the sliding plate frame 85, so that the combing shaft 851 on the sliding plate frame 85 enters the filter hole 811 to dredge the blocked filter hole 811.
