Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an automatic installation device for connecting an infusion tube to an infusion pump. Background Art

[0002] In the medical field, as a key device for precisely controlling the delivery of drugs or nutrient solutions, the stability and accuracy of an infusion pump are directly related to the treatment effect and life safety of patients. By precisely controlling the infusion volume, the infusion pump helps the drugs to be evenly distributed in the patient's body, reducing the fluctuation of drug concentration. This can not only improve the treatment effect but also reduce the side effects caused by uneven drug concentration.

[0003] When medical staff install the infusion tube into the infusion pump, since it is manually installed, it is difficult to determine whether the infusion tube is installed in place. An infusion tube that is not installed in place will result in inaccurate infusion speed and uneven drug concentration, thus affecting the treatment effect.

[0004] Therefore, the present invention proposes an automatic installation device for connecting an infusion tube to an infusion pump to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] Aiming at the defects existing in the prior art, the present invention provides an automatic installation device for connecting an infusion tube to an infusion pump, which can effectively solve the above technical problems.

[0006] The technical implementation solution of the present invention is as follows: An automatic installation device for connecting an infusion tube to an infusion pump, including an infusion device, with an infusion tube clamped on one side of the infusion device. An auxiliary installation mechanism is provided on one side of the infusion device. The auxiliary installation mechanism includes a fixing member detachably connected to one side of the infusion device. A pushing member is threadedly connected to one side of the fixing member. The outer surface of the buckle is threadedly connected to one side of the infusion device. An electric slide rail is fixedly connected to the inside of the fixing member. A sliding member is slidably connected to the inside of the electric slide rail. A moving member is fixedly connected to one side of the sliding member. A connecting member is slidably connected to the outer surface of the moving member. The periphery of the connecting member is arc-shaped. A first spring is fixedly sleeved on the outer surface of the moving member. One end of the first spring is fixedly connected to one side of the connecting member. The connecting member away from the moving member is slidably connected to the pushing member. The lower surface of one side of the pushing member is inclined. The inclined shape on one side of the pushing member is in pressing cooperation with one side of the infusion device. When the pushing member slides downward along the outer surface of the infusion tube, it can limit the position of the infusion tube.

[0007] More preferably, a guide member is fixedly connected to the inner side of the fixing member. A rotating member is rotatably connected to one side of the guide member. The arc surface of the connecting member is in pressing fit with one side of the rotating member. One end of the rotating member is in pressing fit with the inner wall of the guide member. A first torsion spring is fixedly sleeved on the outer surface of one end of the rotating member, and the other end of the first torsion spring is fixedly connected to one side of the guide member. When the rotating member swings, the connecting member can be reset and moved.

[0008] More preferably, a second spring is fixedly sleeved on the outer surface of one side of the pushing member. One end of the second spring is fixedly connected to the inner side of the connecting member. A first rack is fixedly connected to one side of the pushing member. A first gear is meshed with one side of the first rack. The bottom of the first gear is rotatably connected to the inner side of one end of the connecting member. A second rack is meshed with the outer surface of the first gear on the side far from the first rack. The outer surface of one end of the second rack is slidably connected to the inner side of the pushing member. The end of the second rack far from the connecting member is in pressing fit with the infusion tube. When the outer surface of the infusion tube is squeezed by the second rack, the infusion tube can be clamped into one side of the infusion device.

[0009] More preferably, a centering mechanism is further included and is arranged on the upper surface of one side of the infusion device. The centering mechanism includes a third rack fixedly connected to one side of the sliding member. A second gear is meshed with one side of the third rack. A bidirectional screw rod is fixedly connected to one side of the second gear. The outer surface of the bidirectional screw rod is rotatably connected to the upper surface of one side of the infusion device. Centering members are symmetrically threadedly connected to the outer surface of the bidirectional screw rod. When the centering members slide towards each other, the infusion tube can be centered and limited.

[0010] More preferably, a guide rail is fixedly connected to the upper surface of one side of the infusion device. The bottoms of the centering members are slidably connected to the outer surface of the guide rail. When the bottoms of the centering members slide on the outer surface of the guide rail, the position of the centering members can be restricted.

[0011] More preferably, the sides of the centering members close to each other are in an inwardly concave arc shape, so as to avoid excessive squeezing of the infusion tube by the centering members.

[0012] More preferably, a smoothing mechanism is further included and is arranged on the lower surface of the connecting member. The smoothing mechanism includes a plurality of rotating shafts fixedly connected to the bottom of the connecting member. Smoothing members are rotatably connected to the outer surfaces of the rotating shafts. The sides of the smoothing members close to each other are in an unfolded state. The bottoms of the smoothing members are in pressing fit with the outer surface of the infusion tube. When the smoothing members move downward, the bent infusion tube can be smoothed.

[0013] More preferably, both ends of the top of the smoothing member are fixedly connected with second torsion springs. The inner sides of the mutually remote ends of the second torsion springs are fixedly connected to the outer surface of the rotating shaft. Through the second torsion springs, the smoothing member can be flexibly turned when squeezing the infusion tube, thereby avoiding squeezing the infusion tube.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. Through the auxiliary installation mechanism of the present invention, the infusion tube can be installed into the interior of the infusion device in the correct direction and position, greatly reducing the risk of incorrect installation caused by improper human operation, enabling the smooth progress of the infusion process, and also simplifying the installation process of the infusion tube, enabling medical staff to complete the infusion preparation work more quickly and accurately.

[0016] 2. Through the centering mechanism of the present invention, the infusion tube can be kept in a stable centered position during the installation process, and the infusion tube can be accurately aligned with the interior of the infusion device, making it easier for the infusion tube to be inserted into the correct position, avoiding installation errors caused by position deviation, improving the installation accuracy, and increasing the stable connection between the infusion device and the infusion tube.

[0017] 3. Through the smoothing mechanism of the present invention, the infusion tube can be smoothed when the infusion tube is installed into the interior of the infusion device. After being smoothed, the infusion tube can reduce or eliminate internal bending and twisting, enabling the smooth flow of liquid in the tube, helping to maintain a stable infusion speed, and avoiding changes in the flow rate caused by poor pipeline flow.

Detailed implementation manners

[0028] 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Next, the present invention will be further described in conjunction with the embodiments.

[0030] Embodiments of the present invention

[0031] Refer to Figures 1 to 6 As shown, an automatic installation device for connecting an infusion pump pipeline includes an infusion device 1. An infusion tube 101 is clamped to the front side of the infusion device 1. The infusion device 1 is used to push the liquid inside the infusion tube 101. This technology is prior art and will not be elaborated in detail in this embodiment.

[0032] When medical staff install the infusion tube 101 into the infusion device 1, since it is installed manually, it is difficult to determine whether the infusion tube 101 is installed in place. An infusion tube 101 that is not installed in place will cause inaccurate infusion speed and uneven drug concentration, thereby affecting the treatment effect. Therefore, an auxiliary installation mechanism can be used to install the infusion tube 101.

[0033] The auxiliary installation mechanism includes a fixing member 11 detachably connected to the right side of the infusion device 1. A buckle 1101 is threadedly connected to the right side of the fixing member 11. The outer surface of the left end of the buckle 1101 is threadedly connected to the right side of the infusion device 1. The buckle 1101 is used to fix the infusion device 1 and the fixing member 11. An electric slide rail 12 is fixedly connected to the inside of the fixing member 11. A sliding member 13 is slidably connected to the inside of the electric slide rail 12. The sliding member 13 is used to slide up and down inside the electric slide rail 12. A moving member 14 is fixedly connected to the front side of the sliding member 13. The sliding member 13 is used to drive the moving member 14 to move up and down. The outer surface of the top of the moving member 14 is slidably connected to a connecting member 19. The moving member 14 is used to limit the sliding position of the connecting member 19. The outer surface of the top of the moving member 14 is fixedly sleeved with a first spring 15. The front end of the first spring 15 is fixedly connected to the rear side of the connecting member 19. The first spring 15 is used to drive the connecting member 19 to move in a reset manner.

[0034] A pushing member 110 is slidably connected to the left end of the connecting member 19. The bottom of the pushing member 110 is inclined. The inclined shape at the bottom of the pushing member 110 is in extrusion fit with the front side of the infusion device 1. A second spring 111 is fixedly connected to the rear side of the pushing member 110. The front end of the second spring 111 is fixedly connected to the inside of the left end of the connecting member 19. The second spring 111 is used to drive the pushing member 110 to move in a reset manner.

[0035] A first rack 112 is fixedly connected to the right side of the front end of the pushing member 110. When the pushing member 110 moves, it is used to drive the first rack 112 to move simultaneously. The first rack 112 meshes with a first gear 113 on the right side. The bottom of the first gear 113 is rotatably connected to the inside of the left end of the connecting member 19. A second rack 114 meshes with the outer surface on the right side of the first gear 113. The rear end of the second rack 114 is in extrusion fit with the outer surface of the infusion tube 101. The rear end of the second rack 114 is used to extrude the outer surface of the infusion tube 101.

[0036] A guiding member 16 is fixedly connected to the inside of the fixing member 11. A rotating member 17 is rotatably connected to the front side of the guiding member 16. The periphery of the connecting member 19 is arc-shaped. The arc-shaped part on the front side of the connecting member 19 is in extrusion fit with the upper surface of the rotating member 17. The upper end of the rotating member 17 is in extrusion fit with the inner wall of the guiding member 16. A first torsion spring 18 is fixedly sleeved on the outer surface of the left side at the bottom of the rotating member 17. The right end of the first torsion spring 18 is fixedly connected to the left side of the guiding member 16. The first torsion spring 18 is used to drive the rotating member 17 to swing in a reset manner.

[0037] The installation principle of the infusion tube 101 by the auxiliary installation mechanism in this embodiment is as follows: In the initial state, the first spring 15, the first torsion spring 18, and the second spring 111 are all in a natural and relaxed state, and the guide member 16 and the rotating member 17 are in a closed state. When medical staff install the infusion tube 101, at this time, the outer surface of the infusion tube 101 can be aligned with the front side of the infusion device 1 and the electric slide rail 12 is started. The sliding member 13 can move downward inside the electric slide rail 12. When the electric slide rail 12 moves upward, it will drive the connecting member 19 to move simultaneously through the moving member 14. When the connecting member 19 moves downward, the arc surface on the lower surface of the connecting member 19 will be squeezed by the upper surface of the rotating member 17. As the connecting member 19 continues to move downward, the rotating member 17 will cause the connecting member 19 to slide backward and move downward. When the connecting member 19 slides backward, the first spring 15 will be moved to a compressed state. At this time, the connecting member 19 can move downward inside the bottom of the guide member 16.

[0038] When the connecting member 19 moves downward, it will drive the pushing member 110 to move simultaneously. At this time, when the pushing member 110 moves downward, it can restrict the outer surface of the infusion tube 101. And when the pushing member 110 moves downward, the inclined surface at the bottom of the pushing member 110 will be squeezed by the front side of the infusion device 1, causing the pushing member 110 to move forward inside the connecting member 19. When the pushing member 110 moves forward, it will not only drive the first rack 112 to move simultaneously but also drive the second spring 111 to move to a compressed state. As the first rack 112 moves forward, it will drive the first gear 113 to rotate counterclockwise. When the first gear 113 rotates counterclockwise, it will drive the second rack 114 to move backward. When the second rack 114 moves backward inside the pushing member 110, the rear end of the second rack 114 can squeeze the outer surface of the infusion tube 101, prompting the infusion tube 101 to be completely stuck inside the infusion device 1. Thus, it can greatly reduce the risk of incorrect installation caused by improper human operation, ensure the smooth progress of the infusion process, and also simplify the installation process of the infusion tube 101, enabling medical staff to complete the infusion preparation work more quickly and accurately.

[0039] When the inclined surface of the pushing member 110 disengages from the front side of the infusion device 1, the second spring 111 in the compressed state will drive the pushing member 110 to move backward. When the pushing member 110 moves backward inside the connecting member 19, it will drive the first rack 112 to move simultaneously. At this time, when the first rack 112 moves backward, it will drive the second rack 114 to move forward through the first gear 113. At this time, the rear end of the second rack 114 will disengage from the outer surface of the infusion tube 101. As the sliding member 13 drives the connecting member 19 to move to the bottom of the guiding member 16 through the moving member 14, the first spring 15 in the compressed state will drive the connecting member 19 to move forward on the outer surface of the moving member 14, and the sliding member 13 will drive the connecting member 19 to move upward through the moving member 14. As the connecting member 19 moves upward, the upper surface of the connecting member 19 will fit against the lower surface of the rotating member 17 and squeeze the rotating member 17. At this time, the rotating member 17 can swing counterclockwise. When the rotating member 17 swings, the first torsion spring 18 will be rotated to the energy storage state. After the rotating member 17 swings, the connecting member 19 can continue to move upward. At this time, the upper surface of the connecting member 19 will disengage from the lower surface of the rotating member 17, and the first torsion spring 18 in the energy storage state can drive the rotating member 17 to swing clockwise for reset. When the sliding member 13 drives the connecting member 19 to move upward through the moving member 14, the connecting member 19 can return to the initial state again.

[0040] Since the fixing member 11 is detachably connected to the infusion device 1, when the fixing member 11 is not needed, the fixing member 11 can be removed from the right side of the infusion device 1.

[0041] When medical staff installs the infusion tube 101, they need to manually adjust the position of the infusion tube 101. When adjusting the infusion tube 101, it is easy to slide and shift, resulting in an unstable installation position of the infusion tube 101, thereby affecting the infusion accuracy. Therefore, a centering mechanism can be used to limit the infusion tube 101.

[0042] Reference Figure 7As shown in the figure, the centering mechanism includes a third rack 2 fixedly connected to the rear side of the sliding member 13. The sliding member 13 is used to drive the smoothing member 3 to move. A second gear 21 is meshed with the rear side of the third rack 2. A bidirectional screw 22 is fixedly connected to the left side of the second gear 21. The outer surface of the bidirectional screw 22 is rotatably connected to the upper surface of the front side of the infusion device 1. The second gear 21 is used to drive the bidirectional screw 22 to rotate. Symmetrically threaded connection with the outer surface of the bidirectional screw 22 is a centering member 23. The mutually approaching sides of the centering member 23 are in an inwardly concave arc shape. The inwardly concave arc shape of the centering member 23 is used to limit the infusion tube 101. A guide rail 24 is fixedly connected between the upper surfaces of the front side of the infusion device 1. The bottom parts of the centering members 23 are slidably connected to the outer surface of the guide rail 24. The guide rail 24 is used to limit the sliding position of the centering member 23.

[0043] The principle of restricting the infusion tube 101 by the centering mechanism in this embodiment is as follows: In the initial state, the mutually approaching sides of the centering member 23 are in an unfolded state. As the electric slide rail 12 drives the sliding member 13 to move downward, the sliding member 13 can drive the third rack 2 to move simultaneously. Since the rear side of the third rack 2 is meshed with the outer surface of the second gear 21, when the third rack 2 moves downward, it will cause the second gear 21 to rotate. When the second gear 21 rotates, it will drive the bidirectional screw 22 to rotate simultaneously. When the bidirectional screw 22 rotates on the front side of the upper surface of the infusion device 1, at this time, the centering member 23 will move toward the mutually approaching sides on the outer surface of the bidirectional screw 22, and the bottom parts of the centering members 23 will slide on the outer surface of the guide rail 24. As the centering member 23 moves toward the mutually approaching sides, the inwardly concave arc shapes between the centering members 23 can limit the outer surface of the infusion tube 101, prompting the infusion tube 101 to maintain a centered state, and enabling the infusion tube 101 to accurately align with the inside of the infusion device 1, making it easier for the infusion tube 101 to be inserted into the correct position, avoiding installation errors caused by position deviation, improving the installation accuracy, and increasing the stable connection between the infusion device 1 and the infusion tube 101.

[0044] As the electric slide rail 12 drives the sliding member 13 to move upward, the third rack 2 can move simultaneously with the sliding member 13. When the third rack 2 moves upward, the rear side of the third rack 2 can be meshed with the outer surface of the second gear 21 and prompt the second gear 21 to rotate in the opposite direction. When the second gear 21 rotates in the opposite direction, it will drive the bidirectional screw 22 to rotate simultaneously. As the bidirectional screw 22 rotates, it will prompt the centering member 23 to move toward the mutually distant sides, prompting the inwardly concave arc shapes between the centering members 23 to release the restriction on the infusion tube 101.

[0045] When medical staff install the infusion tube 101, the material and softness of the infusion tube 101 are inconsistent, so the infusion tube 101 is prone to bending and twisting during installation. The bent and twisted infusion tube 101 will cause the flow of liquid to be obstructed, resulting in poor infusion or complete blockage. Therefore, a smoothing mechanism can be used to straighten the infusion tube 101.

[0046] refer to Figure 8 and Figure 9 As shown, the smoothing mechanism includes two rotating shafts 31 fixedly connected to the bottom of the connecting member 19, and the outer surfaces of the rotating shafts 31 are rotatably connected with the smoothing members 3, and the sides of the smoothing members 3 close to each other are in an unfolded state, and the sides of the smoothing members 3 close to each other are squeezed and matched with the outer surface of the infusion tube 101, and the smoothing members 3 are used to smooth the infusion tube 101, and the two ends of the top of the smoothing member 3 are fixedly connected with the second torsion spring 32, and the second torsion spring 32 is used to enable the smoothing member 3 to flexibly squeeze the infusion tube 101.

[0047] The principle of smoothing the infusion tube 101 by the smoothing mechanism in this embodiment is as follows: in the initial state, the second torsion spring 32 is in a naturally relaxed state. When the infusion tube 101 is installed on the front side of the infusion device 1 and is twisted, the connecting member 19 can drive the smoothing member 3 to move downward through the rotating shaft 31. When the smoothing member 3 moves downward, the side of the smoothing member 3 that is close to each other can squeeze the outer surface of the infusion tube 101, so that the smoothing member 3 can adjust the position of the infusion tube 101, so that the infusion tube 101 can be smoothed, and the smoothed infusion tube 101 can reduce or eliminate internal bending and twisting, so that the liquid can flow smoothly in the tube, which helps to maintain a stable infusion speed and avoid flow rate changes caused by blocked pipelines.

[0048] When the smoothing member 3 squeezes the infusion tube 101, the smoothing member 3 will swing to the side away from each other. Since the two ends of the top of the smoothing member 3 are fixedly connected to one end of the second torsion spring 32, the second torsion spring 32 will make the smoothing member 3 swing slowly, thereby preventing the smoothing member 3 from squeezing the infusion tube 101 too much and causing wear on the outer surface of the infusion tube 101.

[0049] After the smoothing member 3 has smoothed the infusion tube 101 , the second torsion spring 32 , which is in a force storage state, can drive the smoothing member 3 to reset and swing, so that the smoothing member 3 can return to the initial state.

Accordingly, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
