[0035] The present application is described below in conjunction with Figures 1 to 7 The infusion pump assembly provided by the present application is described.

[0036] Referring to Figures 1 to 3 The infusion pump 10 assembly provided by the present application comprises: an infusion pump 10 and an infusion pump handle 20.

[0037] The infusion pump handle 20 comprises a handle body 210 and a transfer connecting plate 220, the handle body 210 is arranged on the transfer connecting plate 220, and the transfer connecting plate 220 is provided with a locking block 221 on both sides.

[0038] The infusion pump 10 is provided with a locking groove 110 on both sides, and the locking groove 110 is used for sliding fit with the corresponding side locking block 221, so that the transfer connecting plate 220 is detachably connected to the infusion pump 10.

[0039] The infusion pump 10 assembly provided by the present application, by setting the locking block 221 and the locking groove 110 structure between the transfer connecting plate 220 of the infusion pump handle 20 and the infusion pump 10, when transferring, the locking blocks 221 on both sides of the transfer connecting plate 220 are inserted into the locking grooves 110 on the corresponding sides of the infusion pump 10 respectively, and the transfer connecting plate 220 is detachably connected to the infusion pump 10, so that the infusion pump 10 is convenient to transfer by the handle body 210, and when used, only the locking blocks 221 on both sides of the transfer connecting plate 220 are taken out from the locking grooves 110 on the corresponding sides of the infusion pump 10, so that the defect that the existing infusion pump handle 20 structure is relatively complex, resulting in inconvenient carrying and using is solved.

[0040] Specifically, the handle body 210 is arranged at the center position of the outer surface of the transfer connecting plate 220, so that when the handle body 210 is pulled, the infusion pump 10 can be pulled stably through the transfer connecting plate 220. The handle body 210 can be arranged on the transfer connecting plate 220 by fixed connection or detachable connection. Among them, the fixed connection can be integrally arranged, fusion connection, etc., the detachable connection can be clamped, inserted or connected through a threaded connecting piece, etc.

[0041] The locking block 221 is located on the side of the transfer connecting plate 220 opposite to the handle body 210. It is elongated and can be aligned with the corresponding locking grooves 110 on the infusion pump 10 during transfer. Then, the transfer connecting plate 220 is pushed so that the locking block 221 is fully inserted into the locking groove 110. To facilitate the engagement of the locking block 221 with the locking groove 110, the two locking grooves 110 are respectively located on the top sides of the infusion pump 10.

[0042] See Figure 3 As shown, according to some embodiments of the present invention, at least one side of the infusion pump 10 is provided with a locking mechanism 120, which is used to lock the locking block 221 in the locking groove 110. By providing a locking mechanism 120 on at least one side of the infusion pump 10, the locking block 221 can be blocked after it is fully inserted into the locking groove 110, preventing the locking block 221 from coming out of the locking groove 110 during transfer, which would reduce the stability of the infusion pump 10 during transfer or even cause it to fall.

[0043] Specifically, the locking mechanism 120 can adopt a locking pin or the like, which are known in the prior art. For example, when the locking mechanism 120 adopts a locking pin, pin holes can be provided at corresponding positions on the transfer connecting plate 220 and the infusion pump 10. After the locking block 221 is fully inserted into the locking groove 110, the pin holes at corresponding positions on the transfer connecting plate 220 and the infusion pump 10 are aligned. Then, the locking pin can be inserted into the pin hole to lock the locking block 221 and prevent it from coming out of the locking groove 110.

[0044] Preferably, in this embodiment, the infusion pump 10 is symmetrically provided with the aforementioned locking mechanism 120 on both sides, which can stably lock the transfer connecting plate 220. Of course, the aforementioned locking mechanism 120 can also be provided only on one side of the infusion pump 10.

[0045] See Figure 3 and Figure 4As shown, according to some embodiments of the present application, the locking mechanism 120 comprises a mounting groove 121, a lock tongue 122 and an elastic reset member 123, the mounting groove 121 is arranged on the infusion pump 10, the lock tongue 122 is arranged in the mounting groove 121 in the vertical direction, one end of the elastic reset member 123 is connected with the mounting groove 121, and the other end of the elastic reset member 123 is connected with the lock tongue 122. By setting the locking mechanism 120 in the form of the mounting groove 121, the lock tongue 122 and the elastic reset member 123, when the locking block 221 enters the lock slot 110, the elastic reset member 123 can be pressed by the lock tongue 122, so that the elastic reset member 123 is compressed and deformed, and after the locking block 221 completely enters the lock slot 110, the lock tongue 122 can be automatically reset and lifted by the elastic reset member 123, so as to block the retreat path of the locking block 221 and prevent it from being pulled out of the lock slot 110. The structure is simple and easy to operate.

[0046] Specifically, in this embodiment, a guide member 127 is fixedly arranged in the mounting groove 121, and a guide groove is formed on the guide member 127, and the lock tongue 122 is arranged in the guide groove for guiding.

[0047] The mounting groove 121 is located on the side wall of the infusion pump 10, and does not occupy too much internal space of the infusion pump 10. The lock tongue 122 can move in the vertical direction in the mounting groove 121, so as to lock and unlock the locking block 221.

[0048] The elastic reset member 123 can be a reset spring, an elastic pad or the like. For example, when a reset spring is used, one end of the reset spring can be abutted or connected to the inner wall of the mounting groove 121, and the other end of the reset spring can be abutted or connected to the lock tongue 122. When the locking block 221 enters the lock slot 110, the reset spring can be pressed by the lock tongue 122, so that the reset spring is compressed and deformed, and after the locking block 221 completely enters the lock slot 110, the lock tongue 122 can be automatically reset and lifted by the reset spring, so as to block the retreat path of the locking block 221. When the elastic reset member 123 is an elastic pad, the working principle is similar to that of the reset spring, which will not be described here.

[0049] Referring to Figure 3 and Figure 4 As shown, according to some embodiments of the present application, the locking mechanism 120 further comprises an unlocking member 124, the unlocking member 124 is connected with the mounting groove 121 in the vertical direction, and the unlocking member 124 is connected with the lock tongue 122, so as to drive the lock tongue 122 to move in the vertical direction when the unlocking member 124 is actuated. By setting the unlocking member 124, the position of the end of the lock tongue 122 can be lowered by manually actuating the unlocking member 124, so as to release the locking of the locking block 221 by the lock tongue 122, and the locking block 221 can be easily taken out of the lock slot 110.

[0050] Specifically, the outer contour of the unlocking piece 124 is adapted to the shape of the mounting groove 121. In this embodiment, the mounting groove 121 is a U-shaped groove, and the outer contour of the unlocking piece 124 is correspondingly provided in a U-shaped form. When the unlocking piece 124 slides vertically, the two side walls thereof respectively fit the corresponding sides of the mounting groove 121, and the stability is strong. When the unlocking piece 124 is located at the initial position, the bottom thereof fits the bottom of the mounting groove 121, and also has strong stability.

[0051] Referring to Figure 3 and Figure 4 According to some embodiments of the present application, the elastic reset piece 123 is a reset spring, the lock tongue 122 includes a main body part 1221 and a connecting rod 1222 connected to each other, an abutting table 1223 is formed on the side of the main body part 1221 facing the connecting rod 1222, the reset spring is sleeved on the connecting rod 1222, and one end of the reset spring abuts against the first side of the abutting table 1223. By setting the elastic reset piece 123 as a reset spring and providing the connecting rod 1222 on the lock tongue 122, the connecting rod 1222 can limit the reset spring, preventing the axis of the reset spring from deviating.

[0052] In addition, the reset spring has the following advantages compared with the elastic pad and other elastic reset pieces 123. The reset spring can provide consistent and predictable reset force, improving the reliability of the locking mechanism. The reset spring has high fatigue strength and durability, prolonging the service life of the locking mechanism 120. At the same time, the reset spring is designed compactly, occupies less space, is easy to install and maintain, and can flexibly adjust the elasticity and reset force by adjusting the length and material. The reset spring can also provide smooth movement, has strong anti-interference ability, is cost-effective, has wide adaptability, and significantly improves overall performance and user experience.

[0053] Referring to Figure 4 According to some embodiments of the present application, two buckles 125 are provided on the side of the unlocking piece 124 facing the lock tongue 122, a clamping groove is formed between the two buckles 125, the clamping groove is clamped and matched with the main body part 1221, and the side wall of the buckle 125 abuts against the second side of the abutting table 1223. By providing the buckle structure on the side of the unlocking piece 124 facing the lock tongue 122, the unlocking piece 124 and the lock tongue 122 can be conveniently configured as a detachable buckle connection. At the same time, the side wall of the buckle 125 can abut against the second side of the abutting table 1223, which can drive the lock tongue 122 to move vertically and achieve unlocking.

[0054] Specifically, in this embodiment, a supporting protrusion 126 is provided between the two buckles 125. When the unlocking piece 124 is matched with the buckle 125 of the lock tongue 122, the supporting protrusion 126 can support and limit the lock tongue 122, preventing the lock tongue 122 from shaking and improving the stability of the locking mechanism 120.

[0055] The unlocking piece 124, the buckle 125 and the supporting protrusion 126 can be integrally arranged, facilitating processing and manufacturing.

[0056] Referring to Figure 4 and Figure 6 According to some embodiments of the present application, the first guide surface 12211 is arranged on the side of the lock tongue 122 facing the inlet end of the lock slot 110, and the second guide surface 2211 is arranged on the side of the locking block 221 facing the lock slot 110. By arranging the first guide surface 12211 and the second guide surface 2211, when the locking block 221 is pushed into the lock slot 110, the first guide surface 12211 and the second guide surface 2211 are in contact and cooperation, which can press down the lock tongue 122, facilitating the smooth entry of the locking block 221 into the lock slot 110 without the aid of external force to press down the lock tongue 122.

[0057] Specifically, in the present embodiment, the first guide surface 12211 is an inclined guide surface, and the second guide surface is a circular arc guide surface, which can ensure the smoothness and stability of the first guide surface 12211 and the second guide surface 2211 in contact and cooperation.

[0058] Referring to Figure 5 and Figure 6 According to some embodiments of the present application, the transfer connecting plate 220 is provided with a side mounting plate 222 on both sides, and the locking block 221 is arranged on the inner surface of the corresponding side mounting plate 222; the transfer connecting plate 220 is provided with a limiting baffle 223, the two ends of the limiting baffle 223 are connected with the corresponding side mounting plate 222 respectively, and the limiting baffle 223 is used for limiting the locking block 221. By arranging the side mounting plate 222, the installation position of the locking block 221 can be provided, and when the locking block 221 is pushed into the lock slot 110, the side mounting plate 222 can be attached to the side wall of the corresponding side of the infusion pump 10, improving the stability. By arranging the limiting baffle 223, the limiting effect can be achieved, and during the transfer, the locking block 221 can always be located at the designated position in the lock slot 110, and when the limiting baffle 223 abuts against the rear surface of the infusion pump 10, the limiting effect can be achieved.

[0059] In addition, since the two ends of the limiting baffle 223 are connected with the corresponding side mounting plate 222 respectively, the two side mounting plates 222 and the limiting baffle 223 can also improve the structural strength of the transfer connecting plate 220, and prevent deformation.

[0060] Preferably, the main body of the transfer connecting plate 220, the side mounting plate 222, the limiting baffle 223 and the locking block 221 can be integrally arranged, facilitating processing and manufacturing.

[0061] Referring to Figure 5 and Figure 6As shown, according to some embodiments of the present application, the infusion pump handle 20 further comprises a reinforcing plate 230, and the inner surface of the transfer connecting plate 220 is provided with a receiving groove 224, and the reinforcing plate 230 is embedded in the receiving groove 224, and the outer surface of the reinforcing plate 230 is flush with the inner surface of the transfer connecting plate 220. By setting the reinforcing plate 230, the structural strength of the transfer connecting plate 220 can be improved. In addition, by setting the outer surface of the reinforcing plate 230 flush with the inner surface of the transfer connecting plate 220 (i.e. the thickness of the reinforcing plate 230 is equal to the depth of the receiving groove 224), the reinforcing plate 230 and the infusion pump 10 can be prevented from interfering.

[0062] Specifically, in order to reduce the total weight of the infusion pump handle 20, the main body part 1221 of the transfer connecting plate 220 is made of plastic, at this time, by setting the (metal) reinforcing plate 230, the total weight of the infusion pump handle 20 can be kept at a low value under the premise of ensuring the structural strength of the infusion pump handle 20.

[0063] The reinforcing plate 230 can be fixed in the receiving groove 224 by clamping, bonding, threaded fastener connection and the like. As preferred, in the present embodiment, the reinforcing plate 230 is fixed in the receiving groove 224 by screws, which is simple in structure and facilitates disassembly and assembly.
