[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Example 1

[0030] like Figure 1-3 The analgesic pump with a quick-release device 2 shown in the figure comprises an analgesic pump body 1 and a quick-release device 2; knobs 11 are respectively provided on both sides of the analgesic pump body 1; the quick-release device 2 comprises a first mounting end 21, a second mounting end 22 and a connecting arm 23; one end of the connecting arm 23 is fixedly connected to the first mounting end 21, and the other end is fixedly connected to the second mounting end 22; the first mounting end 21 and the second mounting end 22 are both detachably connected to the knob 11. The quick-release device 2 can simultaneously drive the knobs 11 located on both sides of the analgesic pump body 1 to rotate, so that the infusion device can be quickly disassembled and assembled on the driving device.

[0031] In some embodiments of the present application, the first mounting end 21 and the second mounting end 22 are connected to the knob 11 by gluing. The first mounting end 21 is provided with a first adhesive surface, and the second mounting end 22 is provided with a second adhesive surface. The first adhesive surface and the second adhesive surface are both facing the knob 11.

[0032] Alternatively, the first mounting end 21 and the second mounting end 22 are both connected to the knob 11 by screws. When in use, the first mounting end 21 and the second mounting end 22 are placed on both sides of the analgesic pump body 1, and the first mounting end 21 and the second mounting end 22 are kept facing the knob 11, and then the screw is inserted through the first mounting end 21 or the second mounting end 22 and then implanted into the knob 11.

[0033] Alternatively, the first mounting end portion 21 and the second mounting end portion 22 are provided with a slot, and the slot is adapted to the driving arm of the knob 11. When in use, the first mounting end portion 21 and the second mounting end portion 22 can be clamped on the knob 11.

[0034] Specifically, the connecting arm 23 is a regular plate-shaped structure. When the knob 11 is located in the locking position, the connecting arm 23 is in close contact with the side wall of the analgesic pump body 1 .

[0035] In the exemplary embodiment of the present application, the width of the connecting arm 23 is smaller than the width of the first mounting end 21 or the second mounting end 22 , so as to prevent the connecting arm 23 from hindering the rotation of the knob 11 .

[0036] In some examples of the present application, a toggle portion is provided on the side wall of the connecting arm 23. When the knob 11 is in the locked position, the connecting arm 23 is close to the side wall of the analgesic pump body 1, and the medical staff can drive the connecting arm 23 to rotate about the axis of the knob 11 through the toggle portion, so that the knob 11 enters the release position, and the infusion device can be quickly disassembled and assembled on the driving device.

[0037] Specifically, the length of the toggle portion is smaller than the length of the connecting arm 23 , and the width of the toggle portion is smaller than the width of the connecting arm 23 , so as to prevent the toggle portion from hindering the rotation of the knob 11 .

[0038] The toggle portion extends away from the analgesic pump body 1. When the knob 11 is in the locked position, the connecting arm 23 is close to the side wall of the analgesic pump body 1, and the toggle portion protrudes from the surface of the connecting arm 23, making it easy for medical staff to drive.

[0039] Example 2

[0040] like Figure 4-5 As shown, the difference between this embodiment and embodiment 1 is that:

[0041] There is a cavity between the toggle part and the analgesic pump body 1. When the knob 11 needs to be turned to release the locking state between the driving device and the infusion device, the finger can be inserted into the cavity between the toggle part and the analgesic pump body 1 to quickly drive the knob 11 to rotate.

[0042] Example 3

[0043] like Figure 6-8 As shown, the difference between this embodiment and embodiment 2 is that:

[0044] A flexible limiting structure 25 is provided inside the cavity; one end of the limiting structure 25 is fixedly connected to the toggle end, and the other end is detachably connected to the analgesic pump body 1. The flexible limiting structure 25 is a cavity structure with a working port, specifically a suction cup, and the limiting structure 25 can be adsorbed on the analgesic pump body 1 to prevent accidental contact with the quick release device 2, resulting in accidental separation of the drive device and the infusion device.

[0045] In the illustrative example of the present application, the limiting structure 25 encloses a working cavity with a working port, and the working port faces the analgesic pump body 1. When the knob 11 is in the locked position, the connecting arm 23 is in close contact with the side wall of the analgesic pump body 1, and the working port is in close contact with the side wall of the analgesic pump body 1. Atmospheric pressure is applied to limit the positional relationship between the connecting arm 23 and the analgesic pump body 1 to prevent the knob 11 from rotating due to accidental touch.

[0046] In the specific example of the present application, a force relief structure 251 is provided on the outer side of the cavity wall forming the working port. When the infusion device needs to be disassembled, the force relief structure 251 can be pulled to deform the working port, so that the outside air can enter the cavity of the limiting structure 25, and the limiting structure 25 can be removed from the analgesic pump body 1, so that the two knobs 11 can be driven to rotate at the same time through the detachable device, and the driving device and the infusion device can be quickly separated.

[0047] Specifically, the force release structure 251 is a regular columnar structure.

[0048] In the description of this specification, the description with reference to the terms "embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0049] The embodiments described in this application are only part of the embodiments of the utility model, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
