[0041] As attached Figure 1 -Attached Fig.11 As shown, the present invention provides an infusion pump door, comprising a door body 1, an infusion tube guide moving component 2 and an infusion tube limit fixing component 3;

[0042] The door body 1 is arranged on the infusion tube installation panel 41 of the infusion pump body 4. The door body 1 can be integrally formed with the infusion pump body 4, or can be a separate structural member arranged on the infusion pump body 4. The door body 1 is provided with an infusion tube installation groove 13, and the infusion tube installation groove 13 is aligned with the vertical installation position 42 on the infusion tube installation panel 41, wherein the vertical installation position 42 is at least provided with a bubble sensor 43, a peristaltic component 44, a pressure sensor 45 and a liquid stop clamp 46, and is of course not limited to the above-mentioned components. The infusion tube can be passed through the infusion pump body 4. The liquid tube installation groove 13 directly reaches the vertical installation position 42 on the infusion tube installation panel 41, wherein the infusion pump body 4, the infusion tube installation panel 41 and the vertical installation position 42 can adopt the existing conventional structure, that is, the conventional infusion pump body 4 can also be adapted to the infusion pump door provided by the present invention, and the infusion tube installation groove 13 separates the door body 1 into a mutually independent door body I11 and door body II12. It should be noted that the door body I11 and the door body II12 are not limited to two separate door body entities, and they can also be components integrally formed with the infusion pump body 4;

[0043] The infusion tube guide moving assembly 2 includes a mounting rod 21 slidably arranged on the door body Ⅰ11 along the depth direction of the infusion tube installation groove 13, a lifting driving member arranged on the door body Ⅰ11 to drive the mounting rod 21 to rise and fall, and a plurality of connecting rods 22 arranged on the mounting rod 21 at intervals along the length direction of the infusion tube installation groove 13. The other end of the connecting rod 22 is provided with an arc-shaped opening member 23, and the arc-shaped opening member 23 is in the infusion tube installation groove 13. It also includes a rotating driving structure 24 that drives the arc-shaped opening member 23 to rotate around its center of circle, wherein the opening of the arc-shaped opening member 23 is larger than the diameter of the infusion tube, and the infusion tube can be easily entered into the arc-shaped opening member 23. The lifting driving member can be driven by a combination of a micro-electric cylinder, a screw nut and a motor, etc., which is specifically the prior art. In addition, it is preferred to set a slide groove in the door body Ⅰ11, and the mounting rod 21 is slidably set in the slide groove;

[0044] The infusion tube limiting and fixing assembly 3 includes a hinged rod 31 hingedly arranged on the door body II 12, a rotating driving member I for driving the hinged rod 31 to rotate, and a limiting and fixing plate 32 arranged on the hinged rod 31, wherein the limiting and fixing plate 32 is provided with matching structures corresponding to the bubble sensor 43, the peristaltic assembly 44, the pressure sensor 45 and the liquid stop clamp 46 respectively, which can adopt the matching structure on the inner side of a conventional door body, and the rotation stroke of the limiting and fixing plate 32 can cover or move away from the infusion tube installation groove 13, that is, the limiting and fixing plate 32 can be driven to rotate to achieve the limiting of the infusion tube, and a plurality of slots 33 are provided on the end of the limiting and fixing plate 32 away from the hinged rod 31, and the slots 33 correspond one-to-one to the connecting rod 22, and the slots 33 are arranged between two adjacent matching structures.

[0045] Before the infusion pump door provided by the present invention is used to install the infusion tube, the installation rod 21 in the infusion pump door is located on the side of the infusion tube installation groove 13 away from the infusion tube installation panel 41, and the opening of the arc-shaped opening piece 23 is away from the infusion tube installation panel 41, and the limiting fixing plate 32 is rotated to a position away from the infusion tube installation groove 13. At this time, it is in the infusion tube installation preparation state. When the infusion tube needs to be installed, the medical staff holds a section of the infusion tube with both hands and initially straightens it, places the section of the infusion tube on the infusion tube installation groove 13, and embeds it into the multiple arc-shaped opening pieces 23, and then controls the rotation drive structure 24 to work, the arc-shaped opening piece 23 rotates, and the opening of the arc-shaped opening piece 23 faces the infusion tube installation panel 41. At this time, the infusion tube is blocked by the arc-shaped opening piece 23. It cannot be taken out from the infusion tube installation groove 13, and the medical staff can release the infusion tube with both hands and wait for the infusion tube to be automatically installed successfully. During the waiting period, the medical staff can set other settings of the infusion pump; then, the lifting drive member drives the mounting rod 21 to descend until the mounting rod 21, the connecting rod 22 and the arc-shaped opening member 23 move down to the extreme position, so that the arc-shaped opening member 23 and the infusion tube are close to the infusion tube installation panel 41, and finally, the rotating drive member I drives the limiting fixing plate 32 to rotate, covering the infusion tube installation groove 13 and making the infusion tube engage with the bubble sensor 43, the peristaltic component 44, the pressure sensor 45 and the liquid stop clamp 46 on the vertical installation position 42. At this time, the matching structure on the limiting fixing plate 32 can make the infusion tube close to the infusion tube installation panel 41 to complete the installation.

[0046] That is, the present invention can greatly simplify the complexity of medical personnel installing the infusion tube on the infusion pump. The medical personnel only need to hold a section of the infusion tube with both hands and initially straighten it, then move it to the infusion tube installation groove 13 and embed it into the interface of multiple arc-shaped opening parts 23 to complete the medical personnel's steps. The remaining installation steps are automatically completed by the infusion tube guide moving component 2 and the infusion tube limit fixing component 3, which can greatly improve the infusion tube installation efficiency and liberate medical personnel. In addition, the infusion tube guide moving component 2 and the infusion tube limit fixing component 3 can stably and reliably complete the subsequent installation steps, ensuring the success rate and reliability of the installation.
