[0030] This utility model proposes an infusion pump 10.

[0031] Please see Figures 1 to 2 In one embodiment of this utility model, the infusion pump 10 includes a pump body 1, a fixing assembly 2, and an infusion tube 13; the pump body 1 includes a frame 11 and a pump body 12, the pump body 12 is disposed on the frame 11, the frame 11 is provided with a first mounting groove 111, the inner sidewall of the first mounting groove 111 is recessed to form a receiving groove 1111, the inner sidewall of the receiving groove 1111 is provided with a first locking part 1112 and a second locking part 1113 disposed opposite to each other; the fixing assembly 2 includes a first fixing member 21 and a second fixing member 22 that are detachably disposed, one side of the first fixing member 21 is provided with a first fixing groove 211, and one side of the second fixing member 22 is provided with a first fixing groove 211. A second fixing groove 221 is provided on the side. The opening of the first fixing groove 211 faces the second locking part 1113, and the opening of the second fixing groove 221 faces the first locking part 1112. The first fixing groove 211 and the second fixing groove 221 surround each other to form a mounting hole 23. The pump body 12 is connected to the infusion tube 13, and the infusion tube 13 is installed in the mounting hole 23. The first fixing member 21 and the second fixing member 22 are limited and fixed in the receiving groove 1111. The first fixing member 21 is limited and abuts against the first locking part 1112, and the second fixing member 22 is limited and abuts against the second locking part 1113.

[0032] The technical solution of this utility model adopts a fixing component 2, which includes a first fixing member 21 and a second fixing member 22 that can be detachably set. The first fixing groove 211 on the first fixing member 21 and the second fixing groove 221 on the second fixing member 22 form a mounting hole 23. The infusion tube 13 is installed in the mounting hole 23 and fixed in the receiving groove 1111 by the fixing component 2. The first locking part 1112 and the second locking part 1113 respectively limit the first fixing member 21 and the second fixing member 22, thereby preventing the infusion tube 13 from falling off the first mounting groove 111, and thus avoiding the infusion tube 13 being clamped by the front door when the user closes the pump body 12.

[0033] In this embodiment, the pump body 12 is mounted on the frame 11. The pump body 12 drives the flow of liquid in the infusion tube 13, thereby facilitating the adjustment of the liquid flow rate in the infusion tube 13. To facilitate the installation of the infusion tube 13 on the frame 11, a first mounting groove 111 is provided on the frame 11. The first mounting groove 111 is used to install the infusion tube 13, and the inner sidewall of the first mounting groove 111 is recessed to form a receiving groove 1111. To improve the stability of the infusion tube 13 installed in the first mounting groove 111, a fixing component 2 can be installed on the outer peripheral wall of the infusion tube 13. The infusion tube 13 is fixed to the receiving groove 1111 by the fixing component 2. The inner wall of the receiving groove 1111 may be provided with a first locking portion 1112 and a second locking portion 1113 arranged opposite to each other along the second direction. The first fixing groove 211 of the first fixing member 21 is limited and abutted against the first locking portion 1112. The first locking portion 1112 can restrict the first fixing member 21 from moving toward the side away from the first mounting groove 111, thereby preventing the infusion tube 13 from falling out of the first mounting groove 111. The second fixing groove 221 of the second fixing member 22 is limited and abutted against the second locking portion 1113. The second locking portion 1113 can restrict the second fixing member 22 from moving toward the side away from the first mounting groove 111, thereby further preventing the infusion tube 13 from falling out of the first mounting groove 111. The first direction and the second direction intersect. The first direction may be consistent with the left-right direction, and the second direction may be consistent with the up-down direction. Multiple fixing components 2 may be provided. Multiple fixing components 2 are arranged at intervals along the axial direction of the infusion tube 13, thereby improving the stability of the infusion tube 13 installed in the first mounting groove 111. The opening of the first fixing groove 211 faces the second locking portion 1113, thereby aligning the first fixing groove 211 and the first locking portion 1112 along the second direction, so that the first locking portion 1112 better fits the first fixing groove 211. The opening of the second fixing groove 221 faces the first locking portion 1112, thereby aligning the second fixing groove 221 and the second locking portion 1113 along the second direction, so that the second locking portion 1113 better fits the second fixing groove 221.

[0034] like Figure 2 and Figure 7 As shown, the infusion pump 10 also includes a limiting member 3, which includes a connecting section 31 and a locking section 32 connected to each other. The connecting section 31 is located in the frame 11, and the locking section 32 is located in the receiving groove 1111. The locking section 32 has a second locking part 1113.

[0035] In this embodiment, the side of the second locking part 1113 near the second fixing member 22 may have an arc surface, and the cross-section of the second fixing groove 221 along the second direction may be arc-shaped, thereby improving the fit between the second fixing groove 221 and the second locking part 1113, and thus improving the stability of the second fixing member 22 in the receiving groove 1111. By using a limiting member 3 to cooperate with the first locking part 1112 to limit and fix the fixing component 2, the second locking part 1113 on the limiting member 3 is in limiting contact with the second fixing member 22, and the first locking part 1112 is in limiting contact with the first fixing member 21, thereby preventing the infusion tube 13 from falling off. By using a limiting member 3 including a connecting section 31 and a locking section 32 that are connected to each other, the connecting section 31 and the locking section 32 can be integrally formed. The connecting section 31 is used to be installed in the frame 11, and the locking section 32 is used to be in limiting contact with the second fixing member 22, thereby making it easier for the limiting member 3 to be installed in the receiving groove 1111.

[0036] like Figure 5 As shown, the first locking part 1112 includes an abutting section 1114 and a limiting section 1115 connected to each other. The abutting section 1114 has an arc-shaped surface 1116. The limiting section 1115 and the arc-shaped surface 1116 form a buckle 1117. The first fixing member 21 is limited and abuts against the buckle 1117.

[0037] In this embodiment, the cross-section of the first fixing groove 211 along the second direction can be arc-shaped. By using the limiting segment 1115 and the arc-shaped surface 1116 to form the buckle 1117, the buckle 1117 and the groove shape of the first fixing groove 211 are adapted to each other, thereby improving the fit between the first fixing groove 211 and the first locking part 1112, thereby improving the stability of the first fixing member 21 in the receiving groove 1111, and thus better avoiding the phenomenon of the infusion tube 13 falling off the first mounting groove 111.

[0038] like Figure 4 and Figure 7 As shown, the frame 11 has a second mounting groove 112, and the inner sidewall of the receiving groove 1111 has a notch 1118. The receiving groove 1111 is connected to the second mounting groove 112 through the notch 1118. The connecting section 31 is disposed in the second mounting groove 112, and the locking section 32 passes through the notch 1118 so that the locking section 32 is located in the receiving groove 1111.

[0039] In this embodiment, the second mounting groove 112 can be disposed along the second direction on the side of the frame 11 opposite to the first locking portion 1112, so that the limiting member 3 is installed on the side of the receiving groove 1111 opposite to the first locking portion 1112, thereby better limiting and fixing the fixing component 2. The inner sidewall of the receiving groove 1111 opposite to the first locking portion 1112 along the second direction may have a notch 1118, and the receiving groove 1111 communicates with the second mounting groove 112 through the notch 1118. When the connecting section 31 is installed in the second mounting groove 112, the locking section 32 passes through the notch 1118 and extends into the receiving groove 1111, so that the second locking portion 1113 on the locking section 32 is located in the receiving groove 1111, thereby making it easier for the limiting member 3 to limit and fix the second fixing member 22.

[0040] like Figure 2 As shown, the receiving groove 1111 has a third locking part 113 on the inner sidewalls on both sides of the first direction, and the third locking part 113 respectively limits and abuts against the first fixing member 21 and the second fixing member 22.

[0041] In this embodiment, the third locking portion 113 restricts the movement of the first fixing member 21 and the second fixing member 22 along the first direction, thereby improving the stability of the first fixing member 21 and the second fixing member 22 in the receiving groove 1111. The cross-sectional surface of the third locking portion 113 along the second direction can be arc-shaped so that the shape of the third locking portion 113 matches the groove shape of the first fixing groove 211 and the second fixing groove 221, thereby improving the fit between the first fixing groove 211 and the second fixing groove 221 and the third locking portion 113, and further improving the stability of the first fixing member 21 and the second fixing member 22 in the receiving groove 1111, thereby better preventing the infusion tube 13 from falling off the first mounting groove 111.

[0042] like Figure 6 As shown, the first fixing member 21 has a connecting part 212 on the side near the first fixing groove 211, and the second fixing member 22 has a fixing hole 222 on the side near the second fixing groove 221. The connecting part 212 is inserted into the fixing hole 222 so that the first fixing member 21 is connected to the second fixing member 22.

[0043] In this embodiment, the first fixing member 21 is detachably connected to the second fixing member 22, thereby facilitating the installation and removal of the fixing assembly 2 and the infusion tube 13. By using the connecting part 212 inserted into the fixing hole 222, the stability of the connection between the first fixing member 21 and the second fixing member 22 is improved, thereby improving the stability of the connection between the infusion tube 13 and the fixing assembly 2.

[0044] like Figure 3As shown, the infusion pump 10 also includes a mounting base 4 and a fastener 41. The mounting base 4 is mounted on the side of the frame 11 away from the first mounting groove 111 by the fastener 41. The mounting base 4 is provided with a limiting part 42, which abuts against the limiting member 3 to prevent the limiting member 3 from falling off.

[0045] In this embodiment, to improve the stability of the connection between the mounting base 4 and the frame 11, the mounting base 4 is connected to the frame 11 via fasteners 41. By employing a limiting member 3, one side is installed within the second mounting groove 112, and the other side of the limiting member 3 abuts against the limiting portion 42 of the mounting base 4, the limiting member 3 is prevented from falling out of the second mounting groove 112, thereby improving the stability of the limiting member 3 within the second mounting groove 112. It should be noted that the fastener 41 can be a fastening screw or a fastening bolt, etc.

[0046] In this embodiment, the mounting base 4 can be used to install other components inside the pump body 1, such as gear transmission components and control components such as PCBs.

[0047] like Figure 3 As shown, the mounting base 4 includes a first mounting base 43 and a second mounting base 44. The first mounting base 43 is located above the second mounting base 44. The second mounting base 44 is connected to the first mounting base 43 by the fastener 41. The second mounting base 44 is connected to the frame 11 by the fastener 41. The second mounting base 44 is provided with the limiting part 42. The second mounting base 44 abuts against the limiting member 3 through the limiting part 42.

[0048] In this embodiment, the first mounting base 43 can be used to mount the driver, the transmission gear set in the transmission assembly, and the PCB. The second mounting base 44 can be used to cooperate with the first mounting base 43 to assemble components such as the driver and the transmission assembly. The second mounting base 44 may be provided with a limiting part 42 on the side near the frame 11. When the second mounting base 44 is mounted on the frame 11, the limiting part 42 of the second mounting base 44 abuts against the other side of the limiting member 3, thereby preventing the limiting member 3 from falling out of the second mounting groove 112 and improving the stability of the limiting member 3 installed in the second mounting groove 112.

[0049] like Figure 1 As shown, the infusion pump 10 also includes at least two clamping members 5, which are disposed in the first mounting groove 111 and are connected to the infusion tube 13.

[0050] In this embodiment, by employing at least two clamping members 5 disposed in the first mounting groove 111, the clamping members 5 may be provided with clamping parts, and the at least two clamping members 5 clamp the infusion tube 13 through the clamping parts, thereby further improving the stability of the connection between the infusion tube 13 and the first mounting groove 111.

[0051] In this embodiment, the limiting member 3 is an elastic member made of elastic material, which makes it easier to fix the component 2 onto the limiting member 3 and the first locking part 1112.

[0052] like Figure 1 As shown, the fixing component 2 is provided in at least two, the inner sidewall of the first mounting groove 111 has at least two receiving grooves 1111, the at least two receiving grooves 1111 are arranged at intervals along the first direction, each fixing component 2 is correspondingly disposed in one receiving groove 1111, the limiting member 3 is provided in at least two, a portion of each limiting member 3 is correspondingly disposed in one receiving groove 1111.

[0053] In this embodiment, depending on the length of the infusion tube 13, the fixing component 2, the receiving groove 1111, the limiting component 3 and the first locking part 1112 can be increased to at least two, thereby performing multiple limiting and fixing of the infusion tube 13, and further preventing the infusion tube 13 from falling off the frame 11.
