Description

Technical Field

[0001] The invention relates to the technical field of nutrient solution infusion, and in particular to an enteral nutrient solution infusion device. Background Art

[0002] In clinical medicine, enteral nutrition support is one of the important means to ensure that patients get enough nutrition and promote recovery. For patients who cannot get enough nutrition through normal diet, such as patients in the intensive care unit (ICU), patients recovering from surgery, or individuals with digestive system diseases, the infusion of enteral nutrition solution becomes a necessary treatment method. However, in actual application, the temperature control of enteral nutrition solution is an issue that cannot be ignored. Too cold nutrition solution may cause gastrointestinal discomfort in patients, or even cause gastrointestinal dysfunction; while the appropriate temperature can help improve the patient's comfort and reduce the occurrence of complications.

[0003] In traditional enteral nutrition infusion methods, in order to make the nutrient solution reach a suitable temperature before entering the patient's body, the infusion tube is usually preheated by bringing it close to a heat source. This process often requires medical staff to manually fold the infusion tube into an S shape or other shape to increase the contact time between the liquid and the heat source, thereby achieving a better heating effect. Manual operation increases the workload of medical staff, especially when the position of the infusion tube needs to be adjusted frequently. In addition, improper operation may also cause the infusion tube to twist or become blocked, increasing the difficulty of care. Summary of the invention

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0053] Secondly, the term "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0054] Example

[0055] Reference Figure 1-Figure 7 This embodiment provides an enteral nutrition solution infusion device, the enteral nutrition solution infusion device comprising:

[0056] The housing 1 is used to carry other components. The housing 1 is provided with a through-notch 2 for the infusion tube to pass through.

[0057] The partition 3 is fixed inside the shell 1, and divides the shell 1 into chamber 1 and chamber 2, and the chamber 1 is used to place the infusion tube;

[0058] The cover plate 4 is arranged on the housing 1 and is used to open and close the chamber 1. The cover plate 4 is provided with a heating component 5, and the heating component 5 is distributed in an S shape;

[0059] A plurality of toggle assemblies 6 are arranged side by side along the height direction of the partition 3;

[0060] Reference Figure 2-Figure 4, the toggle assembly 6 comprises:

[0061] A rotating shaft 61 is rotatably mounted on the partition 3;

[0062] Two through holes 62 are formed on the partition plate 3, and the two through holes 62 are distributed in a circular array with the rotating shaft 61 as the axis;

[0063] Two sliders 63 slide along the two through holes 62 respectively; the sliders 63 are rotatably connected to the air pipe 64, and an expansion piece is provided at one end of the air pipe 64 passing through the through hole 62; the two sliders 63 are respectively located on both sides of the notch 2;

[0064] Before the infusion tube is folded into an S shape, the expansion member is in an expanded state; after the infusion tube is folded into an S shape, the expansion member is in a contracted state;

[0065] The driving rod 65 is fixed at its middle part on the rotating shaft 61, and both sides of the driving rod 65 are provided with long holes; the other end of the air pipe 64 passes through the long holes;

[0066] The enteral nutrition solution infusion set also includes:

[0067] A driving assembly, used for all the rotating shafts 61 to rotate synchronously;

[0068] The specific working process of the present invention is as follows: when it is necessary to place the infusion tube, the cover plate 4 is opened, and then the infusion tube is placed from the front of the shell 1 into the notch 2. At this time, the two expansion members of the toggle assembly 6 are respectively on both sides of the infusion tube, and the expansion members are in an expanded state. Then the drive assembly is turned on to rotate all the rotating shafts 61. As the rotating shafts 61 rotate, the driving rods 65 connected thereto will also rotate. Since the air pipe 64 passes through the long hole on the driving rod 65, the slider 63, the air pipe 64 and the expansion member are pushed to slide along the through hole 62. Since the two through holes 62 are distributed in a circular array with the rotating shaft 61 as the axis, The two expansion parts of the toggle assembly 6 move in opposite directions, and the expansion parts moving in opposite directions fold the infusion tube into an S shape; because the expansion parts squeeze the infusion tube when folding it into an S shape, which may easily cause blockage of the infusion tube, the expansion parts are then put into a contracted state, and the infusion tube will also undergo elastic deformation and return to its initial state, and no blockage will occur; then the cover plate 4 is closed, and the heating assembly 5 is turned on, the heating assembly 5 heats the chamber to heat the nutrient solution in the infusion tube; after the infusion is completed, the driving mechanism is operated to restore the rotating shaft 61 and the driving rod 65 to their initial positions, the cover plate 4 is opened, and then the infusion tube can be pulled out.

[0069] If the expansion piece is set to a non-circular shape, it is difficult for the expansion piece to rotate during the process of folding the infusion tube into an S shape, and more sliding friction will be generated between the two, causing greater damage to the infusion tube. At the same time, if only one expansion piece is set to a larger size, it is impossible to ensure that the expansion amount of each part of the expansion piece is consistent, and blockage will occur. As a preferred solution of the present invention, refer to Figure 5 , expansion parts include:

[0070] A plurality of annular rings 66 are arranged side by side on the air pipe 64 in a circular shape, and an air hole 67 communicating with the annular rings 66 is provided on the outer wall of the air pipe 64;

[0071] The specific working process of the expansion piece is as follows: when the infusion tube is folded into an S shape, the trachea 64 and the expansion piece rotate, causing less damage to the infusion tube; multiple smaller annular rings 66 are arranged side by side on the trachea 64. Compared with a large annular ring 66, the expansion amount of the smaller annular ring 66 at each position is more uniform, avoiding the problem of infusion tube blockage caused by uneven expansion of a single larger annular ring 66.

[0072] In order to be able to deliver and exhaust gas to the air pipe 64 without hindering the movement of the air pipe 64, as a preferred embodiment of the present invention, refer to Figure 3-Figure 5 , the toggle assembly 6 also includes:

[0073] Air pump 68, fixed in chamber 2;

[0074] Two rotary joints 69 are respectively slidably mounted on both sides of the driving rod 65 along the length direction; the two rotary joints 69 are respectively connected to the two air pipes 64;

[0075] The air pump 68 has two output ends, which are respectively connected to two rotary joints 69 through hoses 610;

[0076] The specific working process is as follows: when the driving rod 65 and the rotating shaft 61 rotate, the slider 63, the air pipe 64 and the expansion member move along the through hole 62, and the air pipe 64 also moves relative to the long hole. In order to adapt to this displacement, the rotary joint 69 is set to be slidably installed on the driving rod 65 along the length direction. The rotary joint 69 can slide with the air pipe 64, and because the hose 610 is set, it will not affect the operation of the air pump 68; and the rotary joint 69 will not affect the rotation of the air pipe 64;

[0077] The air pump 68 can both evacuate the air pipe 64 and inflate the air pipe 64. When inflating, air enters the annular ring 66 along the air pipe 64 and the air hole 67, causing the annular ring 66 to expand and elastically deform, thereby increasing its volume. When evacuating air, the gas in the annular ring 66 is discharged, causing the annular ring 66 to shrink and reduce its volume.

[0078] If the air pipe 64 directly contacts the inner wall of the long hole, the air pipe 64 will be greatly worn and generate noise. As a preferred embodiment of the present invention, refer to Figure 4-Figure 5 , the toggle assembly 6 also includes:

[0079] Bearing, the bearing is fixed on the air pipe 64, and the outer ring of the bearing is in contact with the inner wall of the long hole;

[0080] When the air pipe 64 needs to move in the long hole, the outer ring of the bearing will roll on the inner wall of the long hole instead of sliding directly. This rolling friction is much smaller than the sliding friction, which greatly reduces the friction between the air pipe 64 and the inner wall of the long hole.

[0081] As a preferred embodiment of the present invention, refer to Figure 4 , the toggle assembly 6 also includes:

[0082] Two baffles 611 are respectively fixed on the two air pipes 64, and the cross-sectional area of ​​the baffle 611 is larger than the cross-sectional area of ​​the expansion piece when it is expanded; the infusion tube is between the partition 3 and the baffle 611. When the air pipe 64 moves, the baffle 611 moves with the air pipe 64. Since the cross-sectional area of ​​the baffle 611 is larger than the cross-sectional area of ​​the expansion piece when it is expanded, the infusion tube can be prevented from being separated from the expansion piece.

[0083] In order to reduce the number of power configurations and reduce the cost of use, refer to Figure 3-Figure 4 As a preferred solution of the present invention, the driving assembly includes:

[0084] The power mechanism 7 is fixed in the chamber 2, and the power mechanism 7 adopts a servo motor;

[0085] The power mechanism 7 is transmission-connected to all the rotating shafts 61 . More specifically, the transmission connection between the two can be a synchronous belt or a chain, etc. When the output shaft of the power mechanism 7 rotates, all the rotating shafts 61 can be driven to rotate synchronously.

[0086] As a preferred embodiment of the present invention, refer to Figure 2 The notch 2 is in a smooth arc shape near the cover plate 4. When placing the infusion tube, the smooth arc shape will not cause damage to the infusion tube and the hands of medical staff.

[0087] If both ends of the cover plate 4 are fixedly connected, the user must completely disassemble the cover plate 4 when opening the cover plate 4, which is not only time-consuming and labor-intensive, but also easy to cause damage to the equipment. As a preferred solution of the present invention, refer to Figure 1One end of the cover 4 is rotatably connected to the shell 1 through a hinge 8; the other end of the cover 4 is detachably connected to the shell 1 through a disassembly component 9; connected through the hinge 8, the cover 4 can be easily opened and closed without complicated tools or steps, which greatly simplifies the user's operation and improves the convenience of use of the device.

[0088] If screws are used, tools are required for each removal and installation, which is time-consuming and laborious. As a preferred embodiment of the present invention, refer to Figure 2 and Figure 7 , the disassembly component 9 includes:

[0089] A fixing ring 91 is fixed on the partition plate 3;

[0090] The lock buckle 92 is fixed on the cover plate 4;

[0091] The lock buckle 92 is an elastic member, and one end of the lock buckle 92 away from the cover plate 4 extends outward to form a protrusion 93;

[0092] When the cover plate 4 is fixed, the lock buckle 92 passes through the fixing ring 91, and the protrusion 93 is stuck on the outer wall of the fixing ring 91;

[0093] The specific working process of the disassembly component 9 is as follows: when the cover 4 needs to be closed, gently press the cover 4 with your hand to make the lock buckle 92 pass through the fixing ring 91. After the lock buckle 92 passes through the fixing ring 91, the protrusion 93 of the lock buckle 92 will automatically be stuck on the outer wall of the fixing ring 91 to ensure that the cover 4 is firmly fixed; when it needs to be opened and closed, lightly press the protrusion 93 of the lock buckle 92 with your fingers or special tools to make it shrink inward, and at the same time rotate the cover 4 to make the lock buckle 92 fall out of the fixing ring 91, and the cover 4 can be easily removed without using any tools.

[0094] As a preferred solution of the present invention, a handle 10 is provided on the side of the cover 4 away from the hinge 8, and a plurality of anti-slip stripes are arranged side by side on the handle 10. When opening or closing the cover 4, by holding the anti-slip stripes on the handle 10, medical staff can open and close the cover 4 more easily without directly grabbing the edge of the cover 4, which makes the operation more convenient.

[0095] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
