Description

Technical Field

[0001] The utility model belongs to the field of extension tubes, in particular to a filtering micro pump extension tube. Background Art

[0002] The micro pump extension tube is an important accessory for infusion, nursing and protective equipment. Its main function is to connect the micro pump with the patient or equipment to achieve liquid delivery and control.

[0003] During the use of the micropump extension tube, bubbles will be generated inside it. If the bubbles enter the patient's body, it will aggravate the patient's condition. Nowadays, the bubble removal pipeline may appear vertically downward due to the different placement of the extension tube. At this time, the bubbles will not be able to enter the bubble removal pipeline due to their buoyancy, and will follow the medicine into the patient's body. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a filtering micro pump extension tube.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a filter type micro pump extension tube, comprising a support box, characterized in that: the interior of the support box is hollow, and a support assembly is arranged inside the support box;

[0006] The support assembly includes two rotating pins rotatably connected to the center of the support box, a rotating ball is clamped between the two rotating pins, a support rod is fixed on the rotating ball, a counterweight is fixed at one end of the support rod, and a support block is fixed at the other end, and the pipe is clamped by the support block.

[0007] Optionally, a connecting hole is opened inside the rotating pin, and the connecting hole is arranged in an arc shape, with one side of the connecting hole being located at an end surface of the rotating pin away from the rotating ball, and the other side being located at an outer peripheral side of the rotating pin.

[0008] Optionally, the rotating ball is spherically set, and a spherical groove is also provided on the end face of the rotating pin close to the rotating ball. The rotating ball cooperates with the groove, and the length of the support rod close to the counterweight block with the rotating ball as the center is greater than the length close to the support block.

[0009] Optionally, the support block is arc-shaped and has an opening on its outer peripheral side.

[0010] Optionally, an extension tube is provided on the connecting holes in the support block and the rotating pin, a gas collecting tube is provided on the portion of the extension tube located at the support block, a limiting groove is provided on the inner wall of the support box, and the gas collecting tube abuts against the limiting groove.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the support component, the gravity setting of the counterweight block can be used to keep the support block in an upward state at all times. When the liquid medicine in the extension tube drives the bubbles to move to the support block, the bubbles are always on the side of the extension tube close to the gas collecting tube due to the characteristics of buoyancy. The bubbles can then enter the gas collecting tube, and the support block that is always in an upward state will prevent the bubbles from flowing back and will flow into the patient's body along with the liquid medicine, greatly enhancing its safety.

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0017] As shown in Figure 1-2, a filtering micropump extension tube includes a support box 10, which is characterized in that: the interior of the support box 10 is hollow, and a support assembly is provided inside. The support assembly includes two rotating pins 11 rotatably connected to the center of the support box 10, and a rotating ball 13 is clamped between the two rotating pins 11. A support rod 14 is fixed to the rotating ball 13. A counterweight 15 is fixed to one end of the support rod 14, and a support block 16 is fixed to the other end. The pipe is clamped by the support block 16. The support block 16 is arc-shaped and has an opening on its outer peripheral side. The rotating ball 13 is spherical, and a spherical groove is also provided on the end face of the rotating pin 11 close to the rotating ball 13. The rotating ball 13 cooperates with the groove. The length of the support rod 14 close to the counterweight 15 with the rotating ball 13 as the center is greater than the length close to the support block 16.

[0018] A connecting hole is provided inside the rotating pin 11, and the connecting hole is arranged in an arc shape, and one side of the connecting hole is located at the end face of the rotating pin 11 away from the rotating ball 13, and the other side is located at the outer peripheral side of the rotating pin 11. An extension tube 12 is provided on the connecting hole in the supporting block 16 and the rotating pin 11, and a gas collecting tube 17 is provided on the part of the extending tube 12 located at the supporting block 16. A limiting groove 18 is provided on the inner wall of the supporting box 10, and the gas collecting tube 17 abuts against the limiting groove 18. When the supporting block 16 drives the gas collecting tube 17 to move, the head of the gas collecting tube 17 always remains in the limiting groove 18.

[0019] When in use, the support box 10 can be placed at any position. When the support box 10 is placed vertically, the weight of the counterweight 15 keeps the support block 16 in an upward position at all times, so that the portion of the extension tube 12 can be driven to be always at the top. When the medicine passes through the support block 16, the bubbles on it will also be at the top due to buoyancy. When it passes through the gas collecting tube 17, the bubbles can enter the gas collecting tube 17. The support block 16, which is always in an upward state, will prevent the bubbles from flowing back and will flow into the patient's body with the medicine, greatly enhancing its safety. Moreover, when the support box 10 is placed flat, the gravity of the counterweight 15 will drive the rotating ball 13 to rotate, so that the support block 16 is supported upward. When the medicine drives the bubbles to pass through the support block 16, they will also float to the vicinity of the gas collecting tube 17 and then enter the gas collecting tube 17, further increasing its safety.

[0020] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
