DETAILED DESCRIPTION OF THE INVENTION

[0021] Specific embodiments of the present invention will be described in detail below with reference to the drawings, which should be understood to be used merely for the purpose of illustrating the present invention and not to limit the present invention.

[0022] FIG. 1 is a three-dimensional exploded view of a device for securing a defibrillator according to the present invention, showing the handle and components of a locking mechanism attached to the handle. FIG. 2 is a three-dimensional view of a base assembly of the device for securing a defibrillator according to the present invention, showing the movable unit of the base assembly removed to show the internal structure. FIG. 3 is a three-dimensional view similar to FIG. 2, but with a wire guard added. FIG. 4 is a three-dimensional view of a movable unit of the device for securing a defibrillator according to the present invention. FIG. 5 is a three-dimensional bottom view of the movable unit of FIG. 4. As shown in FIGS. 1-5, a device 1 for securing a defibrillator according to the present invention generally includes a base assembly 3 and an adapter plate 5 removably held on the base assembly 3. The base assembly 3 includes a base 7, a movable unit 9, an actuating mechanism 11 for feeding the movable unit 9 toward the outside of the base 7, a locking mechanism 13 for locking the movable unit 9 in position after it has moved inside the base 7, and a stop mechanism 15 for preventing the adapter plate 5 attached to the movable unit 9 from moving.

[0023] As shown in FIGS. 1 to 3, the base 7 includes a base plate 17 and side plates 19 fixedly disposed on both sides of the base plate 17. The base plate 17 can be fixedly attached to an ambulance. For example, both sides of the base plate 17 can be provided with side wings 21 that protrude from the side plates 19, and each side wing 21 can be provided with a through-hole 23, and the base plate 17 can be fixedly attached to the ambulance by passing screws (not shown) through the through-holes 23.

[0024] 1, 4, and 5, the movable unit 9 includes a substantially flat support plate 25 that can be advanced by the actuating mechanism 11, and a plurality of mounting holes 27 are formed on both sides of the support plate 25. As shown in FIGS. 1, 2, and 3, the actuating mechanism 11 for advancing the movable unit 9 toward the outside of the base 7 includes a guide rod 29 whose ends are fixedly supported on the base plate 17 by support seats 28, a slide block 31 through which the guide rod 29 passes so that the slide block can slide along the guide rod 29, and a first spring 33 that is fitted over the guide rod 29 and applies a spring force to the slide block 31 to push the slide block 31 toward the outside of the base 7 along the guide rod 29. The actuating mechanism 11, including the guide rod 29, the slide block 31, and the first spring 33, can withstand dynamic loads with greater strength and has higher reliability. In the preferred embodiment, a pair of relatively parallel actuating mechanisms 11 is shown, but it should be understood that an arrangement of only one actuating mechanism or more than one actuating mechanism is also feasible. The support plate 25 can be fixed to the slide block 31 by screws (not shown) that pass through mounting holes 27 on the support plate 25 of the movable unit 9 and are screwed into threaded holes 35 in the slide block 31, so that the support plate 25 can move together with the slide block 31. In this way, the support plate 25 (i.e., the movable unit 9) can be automatically and quickly ejected by the action of the first spring 33.

[0025] 5 and 6, the locking mechanism 13 for locking the movable unit 9 in place after it has been moved inside the base 7 includes a lock block disposed on the base plate 17, a lock rod attached to the movable unit 9 and engageable with the lock block to lock the movable unit 9 in the operative position, and an operating component for operating the lock rod to disengage from the lock block. In a preferred embodiment, two lock blocks 37 are provided on the base plate 17, and two L-shaped lock rods 39 are attached to the movable unit 9, each having a hook 41 at a first end proximate to the corresponding lock block 37, and each L-shaped lock rod 39 is pivotally attached to the movable unit 9 by a pivot 43 at its middle corner. In a preferred embodiment, each L-shaped lock rod 39 is attached to a handle 45 for the support plate 25. The operating component includes a pressing component 47 attached to the movable unit 9, particularly the handle 45, and operable to press the second end of each L-shaped lock rod 39. Each L-shaped lock rod 39 pivots around the pivot 43 under the load of the second spring 49, causing the hook 41 formed on the first end of the lock rod to hook onto the corresponding lock block 37 and the second end of the lock rod to contact the pressing component 47. The second end of each L-shaped lock rod 39 is pressed by the pressing component 47, causing the L-shaped lock rod 39 to pivot against the action of the second spring 49, disengaging the hook 41 from the lock block 37 and allowing the movable unit 9 to move together with the slide block 31. The L-shaped lock rod 39 is designed as a spring-loaded lever that converts linear motion into rotational motion to reduce friction between the hook 41 and the lock block 37 during the unlocking process, making the unlocking operation smoother and more convenient.To facilitate movement of the hook 41 so that it passes through the lock block 37 when the movable unit 9 is pushed back inside the base 7, the hook 41 has an inclined surface 42 that contacts the lock block 37 and guides the movement of the hook 41.

[0026] A notch 48 can be formed on support plate 25 for attaching handle 45 to notch 48 for ease of gripping by medical staff, and another notch 50 can be formed in base plate 17 accordingly. Pushing component 47 is preferably located inside handle 45 to prevent accidental contact with push component 47 and allow hook 41 on the first end of L-shaped locking rod 39 to disengage from locking block 37.

[0027] As shown in FIGS. 1 to 4 and 6 , the stop mechanism 15 for preventing the adapter plate 5 attached to the movable unit 9 from moving includes a protruding post 51 disposed on the support plate 25. The protruding post 51 can be inserted into a positioning hole 53 formed in the adapter plate 5 to limit horizontal movement of the adapter plate 5 relative to the support plate 25. In a preferred embodiment, four protruding posts 51 are disposed on the support plate 25, and four corresponding positioning holes 53 are disposed on the adapter plate 5. However, it should be understood that the number of protruding posts 51 and corresponding positioning holes 53 may be less than or greater than four. The upper end of each of the protruding posts 51 may be designed hemispherically to enable the positioning holes 53 to be quickly and accurately inserted into the adapter plate 5, thereby realizing rapid installation of the defibrillator. In addition, in a preferred embodiment, the protruding post 51 is substantially cylindrical, and the positioning holes 53 are circular. The protruding post 51 may have other shapes, such as a rectangular prism, and the positioning holes 53 may be square. Furthermore, it is also possible to arrange a protruding post on the adapter plate and form a positioning hole in the support plate. The stop mechanism 15 for preventing the adapter plate 5 attached to the movable unit 9 from moving further includes stop rods 55 arranged on two side plates 19 of the base 7, respectively, and extending toward the inside of the base 7. The stop rods 55 allow the movable unit 9 and the adapter plate 5 attached to the movable unit 9 to move horizontally, and are spaced a certain distance vertically from the support plate 25 to restrict the adapter plate 5 from moving vertically relative to the support plate 25 after the adapter plate 5 moves horizontally under the stop rods 55 (i.e., after the movable unit 9 and the adapter plate 5 move toward the inside of the base 7). Therefore, two stop rods 55 can be arranged at intervals on each of the side plates 19, and the adapter plate 5 is preferably designed in an I-shape, with each arm of the I-shaped adapter plate 5 provided with a stepped recess 57.When the mobile unit 9 with the adapter plate 5 is inserted inside the base 7, each of the stop rods 55 is received in a corresponding stepped recess 57 to prevent the adapter plate 5 from moving vertically relative to the support plate 25.

[0028] FIG. 8 is a three-dimensional schematic diagram illustrating an adapter plate of a device for securing a defibrillator according to the present invention, attached to the bottom of the defibrillator. As shown in FIG. 8 , the I-shaped adapter plate 5 is fixed to the bottom of the entire defibrillator 61 by a plurality of screws 59 to connect the I-shaped adapter plate 5 to the defibrillator 61. To achieve uniform stress between the I-shaped adapter plate 5 and the defibrillator 61 when the I-shaped adapter plate 5 is connected to the defibrillator 61, a plurality of buffer pads 63 can be arranged on the surface of the I-shaped adapter plate 5 that contacts the defibrillator 61, as shown in FIG. 1 . Similarly, a plurality of additional buffer pads 65 can be arranged on the surface of the I-shaped adapter plate 5 that contacts the support plate 25, as shown in FIG. 8 . When the connected I-shaped adapter plate 5 and the defibrillator are attached to the support plate 25 together, the defibrillator affects quick alignment between the protruding posts 51 on the support plate 25 and the positioning holes 53 on the adapter plate 5. As a result, a guide groove 66 corresponding to the outer surface shape of the adapter plate 5 can be formed in the support plate 25 to facilitate quick alignment between the protruding post 51 and the positioning hole 53 .

[0029] 1 and 3, a wire guard 67 can be disposed at the rear end of the base 7, and the wire guard 67 is provided with a wire hole for passing an electric wire for supplying power to the defibrillator 61. The wire guard 67 is configured to accommodate the electric wire, to prevent medical staff from accidentally touching the power source and receiving an electric shock when the defibrillator 61 is operating, and to prevent the defibrillator from becoming unstable in the vibration environment of an ambulance.

[0030] The base 7 may further include a dustproof wall 71, and the dustproof wall 71, the base 7, and the support plate 25 define a substantially closed space for accommodating the actuating mechanism 11. As a result, as shown in FIG. 10 , the components of the actuating mechanism 11 are not exposed to the external environment. This prevents external dust from contaminating the components of the actuating mechanism, and also prevents blood or body fluids from splashing onto the surfaces of the components of the actuating mechanism, which would otherwise be difficult to clean. The dustproof wall 71 and the base 7 may be integrally formed, preferably by being integrally cast into an aluminum frame.

[0031] Although the locking mechanism 13 is provided, an independent fixing device 73 can be additionally provided to prevent incomplete fixation of the adapter plate and defibrillator attached to the mobile unit 9 due to improper operation of the handle pressing component. FIG. 7 is a partial three-dimensional schematic diagram of an independent fixing device of an apparatus for fixing a defibrillator according to the present invention. As shown in FIG. 7 , the independent fixing device 73 includes a fixing device body 77 attached to the front end plate 75 of the mobile unit 9, a bolt 79 attached to the fixing device body 77, and a stop block 81 attached to the base plate 17 of the base 7. The front end plate 75 of the mobile unit 9 is attached to the front end of the support plate 25 of the mobile unit 9. The independent fixing device 73 further includes a key 83. When not in use, the key 83 can be inserted into the key storage portion 85 of the front end plate 75. When in use, the key 83 is pulled out of the key storage portion 85 and inserted into the fixing device body 77, and the fixing device body 77 and the bolt 79 attached to the fixing device body are rotated. When the bolt 79 rotates to the rear of the stop block 81 on the base plate 17, the movable unit 9 cannot be ejected by operating the pressing component. Only after the bolt 79 rotates and moves away from the rear of the stop block 81 on the base plate 17 can the movable unit 9 be ejected by operating the pressing component, thereby preventing any possible operation errors.

[0032] FIG. 9 shows a schematic three-dimensional view of a device for immobilizing a defibrillator according to the present invention, with the mobile unit ejected from the base and the adapter plate not placed on the mobile unit. FIG. 10 shows a top view of the device for immobilizing a defibrillator in the state shown in FIG. 9. FIG. 11 shows a schematic three-dimensional view of a device for immobilizing a defibrillator according to the present invention, with the mobile unit inserted into the base and the adapter plate fixedly held to the mobile unit. The operation of the device for immobilizing a defibrillator according to the present invention will be described below with reference to FIGS. 9 to 11. To clearly show the operation of the device for immobilizing a defibrillator according to the present invention, the defibrillator 61 mounted on the adapter plate 5 has been removed in FIGS. 9 to 11.

[0033] In normal operation, the device for securing a defibrillator according to the present invention is secured to an ambulance by passing screws (not shown) through holes 23 in side wings 21 protruding from both sides of base plate 17. When it is necessary to use the defibrillator, medical staff first pull out key 83, insert it into fixture body 77, and rotate fixture body 77 and bolt 79 attached to it, so that bolt 79 moves away from the rear of stop block 81 on base plate 17. Then, medical staff grasps handle 45 and pushes in pressing component 47, pivoting L-shaped locking rod 39 against the action of second spring 49, so that hook 41 at the first end of L-shaped locking rod 39 disengages from locking block 37. As a result, due to the action of the first spring 33 contacting the slide block 31, the movable unit 9 including the support plate 25 and the front end plate 75 is automatically and quickly ejected from the base 7 to the outside of the base 7. At this time, as shown in Figures 9 and 10, the support plate 25 moves to a position where the stop rod 55 on the side plate 19 of the base 7 does not prevent the protruding posts 51 of the support plate 25 from being inserted into the positioning holes 53 on the I-shaped adapter plate 5. Then, according to the prompt of the guide groove 66, the protruding posts 51 on the support plate 25 are quickly aligned with and inserted into the positioning holes 53 on the adapter plate 5 to attach the connected I-shaped adapter plate 5 and the defibrillator together to the support plate 25. Next, against the action of the first spring 33, the I-shaped adapter plate 5 and the mobile unit 9 with the defibrillator are pushed back into the base 7 until the hooks 41 of the L-shaped locking rods 39 of the locking mechanism 13 are caught in the corresponding locking blocks 37 under the action of the second spring 49. At this time, the I-shaped adapter plate 5 and the mobile unit 9 with the defibrillator move to a position where each of the stop rods 55 on the side plates 19 of the base 7 is received in a corresponding stepped recess 57 in each of the arms of the I-shaped adapter plate 5, as shown in FIG. 11, to prevent the adapter plate 5 from moving vertically relative to the support plate 25.Finally, the bolt 79 of the fixture body 77 is rotated with the key 83 to the rear of the stop block 81 of the base plate 17. In this way, the defibrillator can be conveniently, quickly, firmly, and reliably fixed to the ambulance.

[0034] The present invention will be described in detail with reference to the preferred embodiments of the present invention, but it should be understood that the detailed description is only used to explain the present invention and is not intended to limit the present invention, and the scope of the present invention is determined by the technical solutions defined in the claims.
