[0037] See also Figures 1 to 9As shown, the present application provides a medical device, which includes a socket 3, a device body 1, a locking member 12 and an upper cover 16. The socket 3 is used to connect with the cable plug 21 of the lead wire 2. The device body 1 is provided with a mounting slide 11, and the cable plug 21 can be plugged and unplugged to the device body 1. The locking member 12 is movably installed in the mounting slide 11, and the locking member 12 is provided with a limiting hole 121. When the cable plug 21 is connected to the device body 1, it is at least partially accommodated in the limiting hole 121. The locking member 12 can move relative to the device body 1 to abut against the buckled cable plug 21 or release the cable plug 21. The locking member 12 is installed in the device body 1, and the cable plug 21 can be fixedly connected in the locking member 12 accordingly. Further control of the locking member 12 can release the cable plug 21. Through the matching and snapping of the cable plug 21 and the locking member 12, the locking force between the cable plug 21 and the device body 1 can be enhanced to prevent the cable plug 21 from falling off, thereby ensuring the connection reliability of the cable plug 21. Moreover, the locking or releasing of the cable plug 21 by the locking member 12 is simple, convenient and quick to operate, and is not easy to cause wear to the cable plug 21, thereby improving the service life of the medical device. Furthermore, the medical device has no exposed redundant elastic wall structure, has a better overall appearance, is simple in shape, is easy to process, saves costs, and ensures the aesthetics of the medical device.

[0038] Specifically, refer to Figures 2 to 5 The medical device further comprises a locking groove 211 arranged on the cable plug 21, and a locking protrusion 122 is convexly arranged on the inner wall of the limiting hole 121 near the locking groove 211. The locking member 12 can move relative to the device body 1 along the first direction, and the cable plug 21 can be plugged and unplugged to the locking member 12 along the second direction, wherein the first direction and the second direction intersect or are perpendicular, the first direction is a direction perpendicular to the plane of the device body 1, and the second direction is a direction parallel to the plane of the device body 1. When the locking member 12 moves along the first direction, the locking protrusion 122 should be locked or released in the locking groove 211. When the locking groove 211 and the locking protrusion 122 have a projection overlap area in the second direction, that is, the locking groove 211 and the locking protrusion 122 are locked and connected; when the locking protrusion 122 moves in the first direction, so that the locking groove 211 and the locking protrusion 122 have no projection overlap area in the second direction, that is, the locking member 12 and the cable plug 21 are unlocked, and the cable plug 21 can be pulled out. Through the cooperating engagement of the locking groove 211 and the locking protrusion 122, the cable plug 21 and the locking member 12 can be quickly locked and released, which is convenient and quick to operate and avoids the problem that the cable plug 21 has its own elastic wall or protruding structure, which makes the lock easy to fail.

[0039] Preferably, in some embodiments, see Figure 4 and Figure 5, along the second direction, when the cable plug 21 is inserted into the locking member 12, at least any one of the end surfaces where the locking protrusion 122 contacts the locking groove 211 is provided with an inclined surface 123. The inclined surface 123 provided on the end surface where the locking protrusion 122 or the locking groove 211 contacts can play a guiding role, reduce the friction and the resisting force between the two, and facilitate the insertion of the cable plug 21. Further, along the direction in which the cable plug 21 is inserted into the locking member 12, the contact surfaces of the locking groove 211 and the locking protrusion 122 of the cable plug 21 can be provided with inclined surfaces 123, which makes it more convenient to insert the cable plug 21, so that the cable plug 21 can be inserted and installed in place with the help of the guidance of the inclined surface 123 without the locking member 12 being in the unlocked state.

[0040] Please continue reading Figure 2 The medical device further includes an elastic member 14, which is installed in the device body 1 and elastically abuts against the locking member 12 and the device body 1. The setting of the elastic member 14 allows the cable plug 21 to reset itself after being inserted into the device body 1, and at this time, the locking member 12 and the locking groove 211 of the cable plug 21 abut against each other to prevent the cable plug 21 from being released. In addition, the setting of the elastic member 14 can also ensure that the locking member 12 is in a locked state in a natural state.

[0041] For details, please refer to Figures 2 to 7 The locking member 12 includes an operating portion 124 and a locking portion 125. The operating portion 124 and the locking portion 125 are integrally formed or detachably connected. The limiting hole 121 is provided on the locking portion 125. The elastic member 14 is also provided in the mounting slot 11. The elastic member 14 includes a first sub-elastic member 141. The first sub-elastic member 141 abuts against the mounting slot 11 and the bottom of the operating portion 124 facing the locking portion 125. The first sub-elastic member 141 abuts against the mounting slot 11 and the operating portion 124. When the operating portion 124 is pressed to release the cable plug 21, the operating portion 124 can reset itself due to the elasticity of the first sub-elastic member 141, thereby improving the user experience of the product. Furthermore, a guide column 1241 is provided on the side of the operating portion 124 facing the mounting groove 11. The setting of the guide column 1241 facilitates the installation of the first sub-elastic member 141 and limits the first sub-elastic member 141 to prevent the position of the first sub-elastic member 141 from shifting, which causes the operating portion 124 to fail to reset in time and affect the product usage experience.

[0042] Preferably, the installation slot 11 passes through the top surface 15 of the device body 1, and the operating surface 1242 of the operating portion 124 facing the top surface 15 at least does not protrude from the top surface 15. The operating surface 1242 can be flush with the top surface 15 or slightly lower than the top surface 15. This arrangement can prevent the cable plug 21 from being dislodged due to accidental touching of the operating portion 124 during operation, thereby ensuring the connection stability of the medical device during operation.

[0043] Please continue to refer to Figure 3 and Figure 7 The locking portion 125 is detachably connected to the operating portion 124. The operating portion 124 includes a mounting portion 1243, and the locking portion 125 includes a connecting portion 1251. The mounting portion 1243 and the connecting portion 1251 are connected.

A stopper step 111 is provided on the inner wall of the mounting slide 11, and the stopper 1244 and the stopper step 111 stop each other. The mounting portion 1243 and the connecting portion 1251 are mutually engaged so that the operating portion 124 can be fixed on the locking portion 125, thereby enhancing the connection stability between the two. Moreover, by pressing the operating portion 124, the locking portion 125 can be driven to move in the first direction, so that there is no horizontal projection overlap between the cable body and the locking member 12, and the cable body is released. Furthermore, a stopper 1244 is protruded from both sides of one end of the side wall of the operating portion 124 facing away from the operating surface 1242, and the stopper 1244 and the stopper step 111 stop each other to prevent the operating portion 124 from detaching from the mounting groove 11, affecting operation and use, and reducing the service life of the medical device.

[0044] In some specific embodiments, the installation slot 11 is provided with a step surface 112, and the elastic member 14 further includes a second sub-elastic member 142, the second sub-elastic member 142 abuts against the bottom of the installation slot 11 and the bottom of the locking portion 125 away from the operating portion 124, and the first sub-elastic member 141 abuts against the operating portion 124 and the step surface 112. Specifically, a cavity 113 is formed between the step surface 112 and the operating portion 124, and the operating portion 124 can slide in the cavity 113 until the stopper 1244 abuts against the step surface 112, at which time the bottom of the locking member 12 also abuts against the bottom of the installation slot 11, and the cable plug 21 can be released and removed. Furthermore, the first sub-elastic member 141 abuts against the operating portion 124 and the step surface 112, and the second sub-elastic member 142 abuts against the bottom of the mounting groove 11 and the locking portion 125, so that the locking member 12 can reset itself under the elastic force of the first sub-elastic member 141 and the second sub-elastic member 142 after the cable plug 21 is pressed to release; or after the cable plug 21 is inserted, the locking groove 211 of the locking member 12 abuts against the locking protrusion 122, thereby locking the cable plug 21 in the device body 1 to prevent the cable plug 21 from loosening.

[0045] In some other embodiments, please refer to Figure 6 and Figure 7The locking part 125 also includes a fixing part 1252. The connecting part 1251 is formed by extending from the end of the locking part 125 close to the operating part 124.
