The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0028] A nutrition pump is an infusion device used for nasogastric feeding of patients. The nutrition pump usually needs to be fixed on a carrier, such as a hanger. The previous fixing structure is relatively complex, consisting of a fixing part and a connecting part, wherein the fixing part and the connecting part are connected to each other, and the fixing part needs to be fixedly connected to the nutrition pump by bolts, and then the connecting part is fixedly connected to the carrier by bolts. The whole assembly process is cumbersome, time-consuming and labor-intensive.

[0029] See also Figure 1-Figure 3 As shown, the nutrition pump provided in this embodiment includes: a nutrition pump body 10 and a clamping mechanism 20, wherein the nutrition pump body 10 is a device for nasogastric feeding of patients, and the clamping mechanism 20 is fixed to the nutrition pump body 10, and the clamping mechanism 20 can be clamped on the carrier in a clamping manner.

[0030] The clamping mechanism 20 includes: a fixed member 21, a movable member 22 and a driving assembly 23. The fixed member 21 is fixed to the nutrition pump body 10, specifically, the fixed member 21 is fixed to the back of the nutrition pump body 10. The movable member 22 is rotatably connected to the fixed member 21, and the fixed member 21 has a fixed clamping portion 210. The movable member 22 has a movable clamping portion 220. After the movable member 22 is rotatably connected to the fixed member 21, the fixed clamping portion 210 and the movable clamping portion 220 are positioned opposite to each other. The driving assembly 23 is fixed to the fixed member 21, and the driving assembly 23 is used to drive the movable member 22 to rotate around the rotation position between the fixed member 21 and the fixed member 21, so that the movable clamping portion 220 moves toward the fixed clamping portion 210, that is, the nutrition pump body 10 can be fixed on the carrier by the movable clamping portion 220 and the fixed clamping portion 210 that are close to each other cooperate to clamp the carrier.

[0031] In actual application, the operator can control the driving component 23 to drive the movable part 22 to rotate around the rotation position between it and the fixed part 21, so that the movable clamping part 220 moves toward the fixed clamping part 210, so that the movable clamping part 220 can move in the direction close to the fixed clamping part 210, so that it can be clamped on the carrier by the movable clamping part 220 and the fixed clamping part 210. Compared with the connection method of bolt fastening, it can effectively simplify the installation process, reduce the difficulty of assembly, and improve the assembly efficiency.

[0032] It should be noted that the operator can manually operate or automatically control the driving component 23 to drive the movable part 22 to rotate around the rotation position between it and the fixed part 21. During the rotation, the movable clamping part 220 can move toward the fixed clamping part 210 to reduce the distance between the two, so that it can be clamped on the carrier.

[0033] In one embodiment of the present application, the surfaces of the fixed clamping part 210 and the movable clamping part 220 are further provided with anti-slip parts, so as to increase the friction between the carrier and the fixed clamping part 210 and the movable clamping part 220 when clamped on the carrier, thereby ensuring the stability of clamping.

[0034] Combination Figure 4-Figure 7 As shown, the clamping mechanism 20 also includes: a reset member 24, which is arranged between the fixed member 21 and the movable member 22. The reset member 24 is used to store elastic potential energy when the movable member 22 rotates around the rotational position between it and the fixed member 21 and moves the movable clamping portion 220 toward the fixed clamping portion 210, so that the movable member 22 rotates in the opposite direction relative to the fixed member 21 and resets.

[0035] Specifically, when the driving assembly 23 drives the movable member 21 to rotate about its rotational position with the fixed member 21 from the initial state, and moves the movable clamping portion 220 toward the fixed clamping portion 210 to clamp the carrier, the reset member 24 can store elastic potential energy until the movable clamping portion 220 rotates to the terminal state of clamping the carrier with the fixed clamping portion 210. After the clamping is completed and the movable member 21 is released by the driving assembly 23, the reset member 24 releases the elastic potential energy, so that the movable member 22 rotates in the opposite direction relative to the fixed member 21, thereby resetting to the initial state.

[0036] In order to realize the rotational connection between the movable member 22 and the fixed member 21, in this embodiment, the clamping mechanism 20 further includes: a rotating shaft 25, two supports 211 are provided on the fixed member 21 at intervals, the two supports 211 are respectively provided with mounting holes 212, the two ends of the rotating shaft 25 are respectively installed in the two mounting holes 212, the movable member 22 is provided with an axial hole 221, and the rotating shaft 25 is passed through the axial hole 221, so that the movable member 22 is rotationally connected with the fixed member 21. The reset member 24 is installed on the rotating shaft 25.

[0037] In this embodiment, the reset member 24 is a torsion spring, and the rotating shaft 25 is passed through the torsion spring. One end of the torsion spring abuts against the fixed member 21, and the other end of the torsion spring abuts against the movable member 22. In this way, elastic potential energy can be stored during the rotation of the movable member 22 along the rotation position between it and the fixed member 21.

[0038] In one embodiment of the present application, in order to facilitate the installation of the reset member 24 , the movable member 22 is further provided with a notch 222 , the shaft hole 221 passes through the notch 222 , and the torsion spring is located in the notch 222 so as to avoid the torsion spring passing through the notch 222 .

[0039] In this embodiment, the driving assembly 23 includes: a driving source 231 and a pushing block 232. The driving source 231 is installed on the side of the fixed member 21 facing the movable member 22, and the pushing block 232 is movably installed on the side of the fixed member 21 facing the movable member 22. The driving source 231 is in transmission connection with the pushing block 232. The movable member 22 is also provided with a butting top portion 223. The driving source 231 is used to drive the pushing block 232 to move, so as to butt against the butting top portion 223, and enable the movable member 22 to rotate around its rotational position with the fixed member 21, so as to move the movable clamping portion 220 toward the fixed clamping portion 210, thereby making the movable clamping portion 220 and the fixed clamping portion 210 close to each other to clamp the carrier.

[0040] In one embodiment of the present application, the driving source 231 includes: a screw rod, a screw hole 233 is provided on the push block 232, the screw rod is screwed into the screw hole 233, and the screw hole 233 is specifically arranged to pass through the push block 232. The screw rod is screwed in the screw hole 233. By rotating the screw rod, the push block 232 can convert the rotational motion of the screw rod into a linear motion along the axial direction of the screw rod, thereby driving the push block 232 to move.

[0041] To ensure that the push block 232 can move linearly, the driving source 23 further includes a positioning block 234, such as Figure 5-Figure 7 As shown, a sliding portion 213 is further provided on the side of the fixed member 21 facing the movable member 22, a push block 232 is slidably arranged on the sliding portion 213, a positioning block 234 is fixed to the end of the sliding direction of the sliding portion 213, and a positioning hole 235 is further provided on the positioning block 234, and a screw rod is passed through the positioning hole 235.

[0042] To facilitate the rotation of the screw rod, the driving source 23 further includes a hand wheel 236 , the end of the screw rod is exposed outside the positioning hole 235 , and the hand wheel 236 is fixed to the exposed end of the screw rod, so that the operator can operate the screw rod to rotate through the hand wheel 236 .

[0043] To summarize, with the nutrition pump provided in this embodiment, the operator can control the driving assembly to drive the movable part to rotate around the rotation position between the movable part and the fixed part, so that the movable clamping part moves toward the fixed clamping part, and the movable clamping part can move toward the fixed clamping part, so that it can be clamped on the carrier by the movable clamping part and the fixed clamping part. Compared with the connection method of fastening with bolts, it can effectively simplify the installation process, reduce the difficulty of assembly, and improve the assembly efficiency.
