Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an automatic device for removing blockages in an infusion pump pipeline. Background Art

[0002] The infusion pump pipeline is a channel for transferring drugs from a syringe or an infusion bottle to a patient's body. Through the control of the infusion pump, the drugs can be accurately infused into the patient's body at a predetermined speed and flow rate. When the infusion pump pipeline is used in conjunction with the infusion pump, precise control of the drug infusion speed and flow rate can be achieved. This is particularly important for treatment scenarios that require strict control of drug dosage and infusion speed.

[0003] When the infusion pump pipeline is injecting drugs into a patient, due to pain, the patient's arm may move involuntarily, which can easily cause the position of the needle in the blood vessel to shift. When the needle is slightly offset, the drug can still enter the blood vessel through the needle, but the flow rate will be significantly reduced. When the needle is severely offset, the drug cannot enter the blood vessel and will accumulate near the infusion pump pipeline, resulting in an obvious blockage of the infusion tube, preventing the liquid from flowing continuously and affecting the treatment effect.

[0039] refer to Figures 7 to 9 As shown, an automatic device for removing blockage of an infusion pump pipeline is shown. The inner side of the top of the pressing member 3 is slidably connected to a pushing member 4. The pressing member 3 is used to drive the pushing member 4 to move up and down.

[0040] refer to Figures 10 to 12As shown in the figure, an automatic device for removing blockage in an infusion pump pipeline is provided. An electric push rod 53 is fixedly connected to the front side of an infusion set 11. A support rod 5 is fixedly connected to the outer surface of the electric push rod 53. A pressing plate 51 is fixedly connected to the front end of the support rod 5. Both the front and rear ends of the pressing plate 51 are inclined. The output end of the electric push rod 53 is fixedly connected to a limiting frame 54. The electric push rod 53 is used to drive the limiting frame 54 to move simultaneously. A return spring 55 is fixedly sleeved on the outer surface of the left side of the limiting frame 54. The top end of the return spring 55 is fixedly connected to a sliding frame 52. The inner side of the sliding frame 52 is slidably connected to the outer surface of the top of the limiting frame 54. The return spring 55 is used to drive the sliding frame 52 to move back to its original position. The left side of the sliding frame 52 is elliptical. The upper surface of the elliptical shape of the sliding frame 52 is in pressing fit with the inclined surface of the lower surface of the front end of the pressing plate 51. The front end of the pressing plate 51 is used to urge the sliding frame 52 to slide downward. The inclined surface of the upper surface of the rear end of the pressing plate 51 is in pressing fit with the lower surface of the elliptical shape of the sliding frame 52. The inclined surface of the rear end of the pressing plate 51 is used to drive the sliding frame 52 to move upward. When the output end of the electric push rod 53 drives the limiting frame 54 to move backward, the sliding frame 52 moves downward and is pressed against the side of the front end of the limiting frame 54 that is closer to each other. Thus, the ends of the sliding frame 52 and the limiting frame 54 that are closer to each other can pull the outer surface of the infusion tube 13, preventing the infusion tube 13 from bending and enabling the infusion tube 13 to remain stable during infusion, being less susceptible to external interference or the influence of patient movement.

[0041] The complete working principle and steps of the above embodiments are as follows:

[0042] Refer to Figures 1 to 4 As shown in the figure, when the device is in the initial state, the rotating member 2 is in the unfolded state, the energy storage spring 221 is in the natural and relaxed state, the bottom of the rear end of the locking member 23 has not yet been engaged with the arc-shaped hole on the front side of the sliding member 22, and the support spring 24 is in the stretched state;

[0043] When using this device to infuse a patient, first, the syringe 12 filled with medicine is clamped to the right side of the infusion set 11, and the rear end of the infusion tube 13 is connected to the front side of the syringe 12. Then, the outer surface of the front end of the infusion tube 13 is slidably clamped to the upper surface of the first fixing member 1. Subsequently, the first fixing member 1 is placed on the patient's wrist. At this time, the bottom of the sliding member 22 can fit against the patient's wrist, and the medical staff can squeeze the first fixing member 1 downward to cause the sliding member 22 to move upward. When the sliding member 22 moves upward, it will drive the energy storage spring 221 to move simultaneously, making the energy storage spring 221 move to a compressed state. When the sliding member 22 moves upward, it will drive the first rack 25 to move simultaneously. When the first rack 25 moves upward, it will cause the left first gear 26 to rotate counterclockwise and the right first gear 26 to rotate clockwise. While the first gear 26 rotates, it will drive the rotating member 2 to swing simultaneously. While the rotating member 2 swings, it will drive the rubber pad 21 to swing simultaneously, enabling the rotating member 2 to drive the rubber pad 21 to fix the patient's wrist, thereby preventing the needle of the infusion tube 13 from bending during injection, avoiding blockage of the infusion tube 13, and enabling the medicine to be continuously and stably infused into the patient's body. Moreover, when the sliding member 22 moves upward, it will drive the limit frame 231 to move simultaneously. When the limit frame 231 moves upward, it will cause the bottom of the rear side of the locking member 23 to slide on the front side of the limit frame 231. As the upper surface of the sliding member 22 fits against the lower surface of the first fixing member 1, the arc groove on the front side of the sliding member 22 just fits against the bottom of the rear end of the locking member 23. At this time, the support spring 24 in a stretched state will drive the locking member 23 to move backward, and the bottom of the rear end of the locking member 23 can be inserted into the arc groove on the front side of the sliding member 22, thereby being able to prevent the energy storage spring 221 from driving the sliding member 22 to move and preventing the rotating member 2 from becoming loose when fixing the patient's arm.

[0044] When the patient's infusion is completed, the medical staff can pull out the locking member 23 forward, so that the bottom of the rear end of the locking member 23 disengages from the arc groove on the front side of the sliding member 22. At this time, the energy storage spring 221 in a compressed state can drive the first fixing member 1 to move upward. When the first fixing member 1 moves upward, it will drive the first gear 26 to move simultaneously through the rotating member 2. When the first gear 26 moves upward, the outer surface of the first gear 26 will move along the mutually separated side of the first rack 25, so that the left first gear 26 drives the left rotating member 2 to swing clockwise, and the right first gear 26 drives the right rotating member 2 to swing counterclockwise, prompting the rotating member 2 to release the fixation of the patient's arm and enabling the rotating member 2 to return to its initial state.

[0045] Reference Figure 5 and Figure 6 As shown, when the device is in the initial state, the rotating plate 31 and the fixing plate 32 are in a horizontal state. The outer surface of the bottom of the first screw 34 is threadedly connected to the top of the rear side of the rotating plate 31, and the torsion spring 37 is in an energy storage state;

[0046] As the sliding member 22 moves upward, the distance between the sliding member 22 and the first fixing member 1 gradually decreases, and the patient's palm can gradually fit against the lower surface of the pressing member 3. Since the depression degree of the patient's palm is different, at this time, the medical staff can rotate the first screw rod 34. When the first screw rod 34 rotates on the upper surface at the rear side of the rotating plate 31, it drives the pressing member 3 to move downward. When the pressing member 3 slides downward on the upper surface of the rotating plate 31, it drives the connecting rod 33 to move simultaneously. At this time, when the connecting rod 33 moves downward, it drives the second rack 35 to rotate clockwise. When the second rack 35 rotates clockwise, it drives the rotating plate 31 to rotate simultaneously. When the second rack 35 then moves downward and disengages from the outer surface of the second gear 36, the torsion spring 37 in the energy storage state drives the rotating plate 31 to flip further through the second gear 36. At this time, when the rotating plate 31 flips clockwise, it drives the pressing member 3 to flip simultaneously, so that the top of the pressing member 3 can fit and press against the palms of different patients, thus avoiding palm flipping, enabling the drug in the infusion tube 13 to smoothly enter the patient's body, preventing pipeline blockage, and also enabling the infusion speed to be stable, so that the drug can enter the patient's body at a predetermined speed and dose.

[0047] When the patient has finished the injection, the medical staff can rotate the first screw rod 34 in the reverse direction. When the first screw rod 34 rotates in the reverse direction, it drives the pressing member 3 to move upward. When the pressing member 3 moves upward, it drives the second rack 35 to move simultaneously through the connecting rod 33. When the second rack 35 moves upward, it meshes with the outer surface of the second gear 36 and causes the second gear 36 to rotate counterclockwise. When the second gear 36 rotates counterclockwise, it drives the rotating plate 31 to swing simultaneously, so that the upper surface between the rotating plate 31 and the fixing plate 32 returns to the horizontal state again. And when the second gear 36 rotates counterclockwise, it also drives the torsion spring 37 back to the energy storage state.

[0048] Reference Figures 7 to 9As shown, when the pressing member 3 moves downward, it can drive the pushing member 4 to move simultaneously, prompting the bottom of the pushing member 4 to contact the patient's palm. Moreover, when the pushing member 4 moves downward, it can also drive the threaded sleeve 42 to move simultaneously through the second screw rod 41. At this time, the threaded sleeve 42 can drive the third gear 43 to move simultaneously. When the third gear 43 moves downward, it can engage with the left side of the third rack 45 and prompt the third gear 43 to rotate counterclockwise. When the third gear 43 rotates counterclockwise, it can drive the threaded sleeve 42 to rotate simultaneously inside the second fixing member 44. When the threaded sleeve 42 rotates counterclockwise, it can drive the pushing member 4 to move forward through the second screw rod 41, prompting the pushing member 4 to move forward while fitting to the patient's palm, enabling the pushing member 4 to push the patient's fingers flat, thereby avoiding the blood vessels being narrowed or displaced due to the pressure or stretching caused by the bending of the fingers, and enabling the injected drug to enter the blood vessels according to the predetermined dose and time, thus improving the treatment effect.

[0049] When the injection for the patient is completed, the pressing member 3 can drive the second screw rod 41 to move upward through the pushing member 4. The second screw rod 41 can drive the third gear 43 to move simultaneously through the threaded sleeve 42. When the third gear 43 moves upward, it will fit to the left side of the third rack 45 and prompt the third gear 43 to rotate clockwise. When the third gear 43 rotates clockwise, it can drive the second screw rod 41 to move backward through the threaded sleeve 42. When the second screw rod 41 moves backward, it can drive the pushing member 4 to move simultaneously, prompting the pushing member 4 to return to the initial state.

[0050] Reference Figures 10 to 12 As shown, when the infusion tube 13 bends during the infusion process, the electric push rod 53 can be activated. At this time, the output end of the electric push rod 53 will drive the limiting frame 54 to move backward. When the limiting frame 54 moves backward, it will drive the sliding frame 52 to move simultaneously. When the sliding frame 52 moves backward, the elliptical upper surface of the sliding frame 52 will be squeezed by the inclined surface on the front side of the pressing plate 51, causing the sliding frame 52 to slide downward. When the sliding frame 52 slides downward, it will squeeze the return spring 55 into a compressed state. At this time, the mutually approaching ends on the right side of the sliding frame 52 and the limiting frame 54 can clamp the outer surface of the infusion tube 13 and drive the infusion tube 13 to move backward, thereby being able to pull the outer surface of the infusion tube 13 to avoid the bending of the infusion tube 13, enabling the infusion tube 13 to remain stable during the infusion process and being not easily affected by external forces or patient activities.

[0051] When the output end of the electric push rod 53 drives the sliding frame 52 to move backward through the limiting frame 54, the elliptical upper surface of the sliding frame 52 will separate from the bottom of the pressing plate 51. At this time, the reset spring 55 in the compressed state will drive the sliding frame 52 to move upward, so that the sliding frame 52 separates from the clamping of the infusion tube 13 at the end where the right side of the limiting frame 54 is close to each other. When the output end of the electric push rod 53 drives the sliding frame 52 to move forward through the limiting frame 54, at this time, the elliptical lower surface of the sliding frame 52 will press against the inclined surface at the rear end of the pressing plate 51, and promote the sliding frame 52 to slide upward. When the sliding frame 52 slides upward, it will cause the reset spring 55 to be moved to the stretched state. When the electric push rod 53 drives the sliding frame 52 and the limiting frame 54 to return to the initial state, the elliptical lower surface of the sliding frame 52 will separate from the upper surface of the pressing plate 51, and the reset spring 55 in the stretched state will drive the sliding frame 52 back to the initial state.
