Specifically, in some embodiments, the offboard power module 30 includes a power housing 31, a battery 32, and a locking assembly 33. The battery 32 and the locking assembly 33 are accommodated in the power supply housing 31. The battery 32 is used to power functional components in the medical device. And the locking component 33 is used for being matched with the clamping piece 21 on the matching part 20, so as to clamp and lock the external power supply module 30 and the matching part 20 with each other or separate from each other.

Referring specifically to fig. 3, the power supply housing 31 has a battery receiving cavity 311, a locking member receiving groove 312, and an opening 313. The battery 32 is accommodated in the battery accommodating chamber 311. The two ends of the power supply housing 31 near the opening 313 are extended with a second positive elastic sheet 315 and a second negative elastic sheet 316 which are connected to the battery 32. When the external power module 30 is engaged with the engaging portion 20, the second positive elastic piece 315 and the second negative elastic piece 316 can be accommodated in the first cavity 111 and are respectively in contact with the first positive elastic piece 51 and the first negative elastic piece 52, so that the battery 32 supplies power to the functional components of the medical device.

The extending direction of the locking device receiving slot 312 in the power housing 31 (i.e., the direction indicated by the arrow X in fig. 3) is perpendicular to the plugging direction (i.e., the direction indicated by the arrow Y in fig. 3) in which the external power module 30 is snapped or plugged into the mating portion 20, or the extending direction of the locking device receiving slot 312 is perpendicular to the direction in which the second positive electrode elastic piece 315 and the second negative electrode elastic piece 316 are received in the first cavity 111.

Referring further to fig. 3-6, the locking assembly 33 is received in the locking assembly receiving slot 312 and is removably engaged with the engaging member 21. In some embodiments, the locking assembly 33 may generally include a push plate 331, a first connecting plate 332, a second connecting plate 333, a first catch 334, and a second catch 335. The first connecting plate 332 and the second connecting plate 333 are slidably connected to the push plate 331 and are respectively disposed on two opposite sides of the push plate 331. In some embodiments, the first connecting plate 332 is disposed on a side of the pushing plate 331 close to the battery receiving cavity 311, and the second connecting plate 333 is disposed on a side of the pushing plate 331 away from the battery receiving cavity 311. The first catch 334 is disposed on the first connecting plate 332, and the second catch 335 is disposed on the second connecting plate 333. The first catch 334 and the second catch 335 each extend in a direction away from the battery receiving cavity 311. Thus, when the external power module 30 is matched with the matching part 20, the first and second retainers 334 and 335 can extend into the first chamber 111 to match with the engaging member 21 received in the first chamber 111.

Specifically, the push plate 331 has a first side surface, a second side surface, and a first active surface, which are disposed opposite to each other, and the first active surface connects the first side surface and the second side surface. The first side surface is disposed on a side of the pushing plate 331 close to the first connecting plate 332, and the second side surface is disposed on a side of the pushing plate 331 close to the second connecting plate 333. The first active surface of the push plate 331 is exposed to the external power supply module 30 through the opening 313. An external force may be applied to the acting surface of the push plate 331 to slide the push plate 331 along the extending direction of the locking member receiving groove 312.

A first push post 3312 is provided on an opposite first side of the push plate 331. The first connecting plate 332 is correspondingly provided with a first sliding slot 3321, and the first pushing post 3312 is accommodated in the first sliding slot 3321 and can slide along the first sliding slot 3321. Similarly, a second push post 3313 is provided on a second side of the push plate 331. The second connecting plate 333 is correspondingly provided with a second sliding slot 3331, and the second pushing post 3313 is accommodated in the second sliding slot 3331 and can slide along the second sliding slot 3331. In some embodiments, as shown in fig. 5, an angle between the extending direction of the sliding grooves 3321 and 3331 and the direction of the external force is acute, that is, an angle between the extending direction of the sliding grooves 3321 and 3331 and the sliding direction of the push plate 331 in the locking element receiving groove 312 is acute.

The first catch 334 includes a first extended rod 3341 and a first projection 3342. One end of the first extended rod 3341 is disposed on the first connecting plate 332, the other end extends in a direction away from the battery accommodating cavity 311, and the first protrusion 3342 is disposed at the other end of the first extended rod 3341 and substantially forms a hook shape with the first extended rod 3341. The first protrusion 3342 has a first protrusion inner surface adjacent to the battery receiving cavity 311 and facing the first connection plate 332, and the first engaging portion 211 has a first engaging portion inner surface adjacent to the receiving cavity 110. The second retaining member 335 includes a second extending rod 3351 and a second protrusion 3352, wherein one end of the second extending rod 3351 is disposed on the second connecting plate 333, the other end extends in a direction away from the battery accommodating cavity 311, and the second protrusion 3352 is disposed at the other end of the second extending rod 3351 and substantially forms a hook shape with the second extending rod 3351. The second protrusion 3352 has a second protrusion inner surface adjacent to the battery receiving cavity 311 and facing the first connection plate 332, and the second engaging portion 212 has a second engaging portion inner surface adjacent to the receiving cavity 110. As shown in fig. 4 and 6, when the locking assembly 33 and the engaging member 21 are engaged, the first protrusion inner surface abuts against the first engaging portion inner surface, and the second protrusion inner surface abuts against the second engaging portion inner surface, so as to fix the external power module 30 and the device housing 10 through the engaging portion 20, at this time, the outer surface of the external power module 30 is flush with the outer surface of the device housing 10, and the battery 32 can stably and continuously supply power to each functional element of the medical device.

Referring to fig. 7, fig. 7 is another cross-sectional view of a medical device according to an embodiment of the present application in a first assembled state. The push plate 331 includes a second active surface opposite to the first active surface, and the second active surface is also connected to the first side surface and the second side surface. The locking assembly 33 further comprises an elastic member 336, and a boss 3314 is provided on the second acting surface of the push plate 331. The elastic member 336 is sleeved on the boss 3314. In some embodiments, the elastic member 336 may be, for example, a spring, an elastic strip, or other elastic member made of an elastic material (e.g., elastic rubber).

When the external power module 30 and the device housing 10 are mutually engaged with each other through the engaging portion 20, the inner surface of the first protrusion abuts against the inner surface of the first engaging portion, the inner surface of the second protrusion abuts against the inner surface of the second engaging portion, the elastic member 336 is not elastically deformed, the first push post 3312 abuts against the side wall of the first sliding groove 3321 near the first acting surface of the push plate 331, and the second push post 3313 abuts against the side wall of the second sliding groove 3331 near the first acting surface of the push plate 331. When the external power module 30 needs to be detached from the device housing 10, a user can apply a pushing force to the first acting surface of the pushing plate 331 to slide the pushing plate 331 along the locking member receiving slot 312 away from the opening 313, so as to press the elastic member 336, such that the first pushing post 3312 applies a pushing force to the slot wall of the first sliding slot 3321, and the second pushing post 3313 applies a pushing force to the slot wall of the second sliding slot 3331. Thus, the first connecting plate 332 moves away from the first housing 11, and the second connecting plate 333 moves away from the second housing 12. When the first pushing post 3312 slides to the other end of the first sliding slot 3321 away from the first acting surface and the second pushing post 3313 slides to the other end of the second sliding slot 3331, the first protrusion 3342 disposed on the first connecting plate 332 is separated from the first engaging portion 211, and the second protrusion 3352 disposed on the second connecting plate 333 is separated from the second engaging portion 212, so as to separate the external power module 30 from the device housing 10. After the external power module 30 is separated from the device housing 10, the user can remove the pushing force applied to the first active surface of the pushing plate 331, and the elastic member 336 resets the locking assembly 33 by using the elastic force.

It can be understood that, in the present embodiment, the external power module 30 includes two connection plates, and two push posts corresponding to the two connection plates are disposed on the push plate 331. In other embodiments, the number of the connecting plates can be set according to actual requirements, for example, two connecting plates can be a connecting plate integrally arranged, or a connecting plate is arranged on only one side of the push plate 331. The number of the sliding grooves on each connecting plate can also be set according to actual requirements, for example, two or more sliding grooves can be set, and the connecting plates can move away from the clamping piece 21 under the pushing action of the pushing posts on the pushing plate 331. Similarly, the number of the retaining members disposed on the connecting plate may also be set according to actual requirements, as long as the external power module 30 can be stably connected to the device housing 10 by the cooperation of the retaining members and the engaging member 21.
