Technical Field

[0001] This utility model relates to the field of call device technology, and in particular to a call device for nursing care. Background Technology

[0002] Medical call devices are key equipment in medical institutions used by patients to call medical staff in emergencies. Modern medical call devices generally adopt wireless transmission technology and have functions such as two-way intercom, hierarchical alarm, and location display.

[0003] A search revealed that Chinese Patent Publication No. CN217157408U discloses a novel medical nursing call device. This device uses screws installed into the T-shaped holes on the four corner round blocks to fix the filter screen to the call device. The filter screen covers the sound holes on the call device, preventing the sound holes from being blocked by dust and affecting the sound transmission. This solves the problem that the voice broadcast port of the device becomes blocked by dust and affects the sound transmission due to long-term use.

[0004] While the filter structure of this patent effectively prevents the sound holes from being clogged by dust, it has been found in actual use that a large amount of dust gradually accumulates on the surface of the filter as the equipment runs for a long time. The filter of this patent is installed with the caller by multiple sets of screws. When it is necessary to remove the filter and clean the dust, multiple screws need to be removed one by one, which is not only cumbersome and time-consuming, but also increases the workload of daily maintenance. Therefore, a caller device for nursing care is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 6This utility model provides an embodiment of a nursing call device, including a caller 1. The caller 1 has a sound outlet 2 on its front side. A positioning block 3 is fixedly installed on the front side of the caller 1. The side of the positioning block 3 away from the sound outlet 2 is open. A locking block 61 extends into the interior of the positioning block 3 through the opening. A loudspeaker cover 4 is snapped onto the outer wall of the positioning block 3. The loudspeaker cover 4 has a trapezoidal structure. The loudspeaker cover 4 can constrain the diffused sound waves in a specific direction, which helps to extend the sound propagation distance so that nursing staff can detect the sound in time. A dustproof net 5 is fixedly installed on the inner wall of the loudspeaker cover 4. The dustproof net 5 on the inner wall of the loudspeaker cover 4 can prevent dust from accumulating inside the sound outlet 2. The loudspeaker cover 4 is provided with a disassembly and assembly mechanism 6. A protective mechanism 7 is provided inside the caller 1.

[0035] Reference Figure 3 - Figure 5 The disassembly and assembly mechanism 6 includes a locking block 61. When the locking block 61 enters the interior of the positioning block 3 through the opening of the positioning block 3, it can limit the loudspeaker cover 4 and the positioning block 3 together. The locking block 61 is slidably connected to the inner wall of the loudspeaker cover 4. A return spring 62 is fixedly installed on the outer wall of the locking block 61. The end of the return spring 62 away from the locking block 61 is fixedly installed on the inner wall of the loudspeaker cover 4. The elasticity of the return spring 62 can drive the locking block 61 to slide and return to its original position. A ball joint rod 63 is fixedly installed on the side wall of the locking block 61. When the ball joint rod 63 pushes the locking block 61, the locking block 61 will gradually slide into the interior of the loudspeaker cover 4 and compress the return spring 62. At the same time, the locking block 61 will gradually move out of the interior of the positioning block 3. An inclined block 64 is slidably connected to the inner wall of the loudspeaker cover 4. An inclined plate is fixedly installed on the top of the inclined block 64. The faceplate 65 has an inclined surface at the end away from the button 67. The end of the ball joint 63 away from the locking block 61 is attached to the inclined surface of the faceplate 65. As the faceplate 65 moves, its inclined surface will squeeze the ball joint 63, causing the ball joint 63 to push the locking block 61. A first spring 66 is fixedly installed on the side wall of the inclined block 64. As the inclined block 64 gradually moves away from the button 67, it will drive the faceplate 65 to move synchronously and compress the first spring 66. The inner wall of the amplifier cover 4 is slidably connected to the button 67. The end of the inclined block 64 near the button 67 is inclined. The bottom of the button 67 is attached to the inclined surface of the inclined block 64. Pressing the button 67 will cause the button 67 to squeeze the inclined surface of the inclined block 64. At this time, the inclined block 64 will slide on the inner wall of the amplifier cover 4 and gradually move away from the button 67.

[0036] Reference Figure 2 - Figure 3The protective mechanism 7 includes a baffle 71, which is slidably connected to the inner wall of the loudspeaker cover 4. When the baffle 71 slides back to its original position on the inner wall of the caller 1, it can cover the sound outlet 2, preventing impurities from entering the interior of the sound outlet 2 after the dustproof net 5 is removed. A second spring 72 is fixedly installed on the side wall of the baffle 71. The end of the second spring 72 away from the baffle 71 is fixedly installed on the inner wall of the loudspeaker cover 4. When the loudspeaker cover 4 is separated from the positioning block 3, the second spring 72 can drive the baffle 71 to slide back to its original position on the inner wall of the caller 1. An L-rod 73 is fixedly installed on the side wall of the baffle 71. The end of the L-rod 73 away from the baffle 71 is attached to the outer wall of the loudspeaker cover 4. When the loudspeaker cover 4 and the positioning block 3 are gradually connected, since the loudspeaker cover 4 has a trapezoidal structure, the inclined surface of the loudspeaker cover 4 will squeeze the L-rod 73, causing the L-rod 73 to push the baffle 71.

[0037] Working principle: When in use, the loudspeaker cover 4 can confine the diffused sound waves in a specific direction, which helps to extend the sound propagation distance so that nursing staff can detect it in time. At the same time, the dustproof net 5 on the inner wall of the loudspeaker cover 4 can prevent dust from accumulating inside the sound outlet 2.

[0038] When it is necessary to disassemble the loudspeaker cover 4 to clean the dust filter 5, press the two sets of buttons 67 on the loudspeaker cover 4 to slide the buttons 67 into the interior of the loudspeaker cover 4. At the same time, the buttons 67 will press the inclined surface of the inclined block 64, causing the inclined block 64 to slide on the inner wall of the loudspeaker cover 4 and gradually move away from the buttons 67. Simultaneously, the inclined block 64 will drive the inclined platform 65 to move synchronously and compress the first reed 66. As the inclined platform 65 moves, its inclined surface will press the ball head rod 63, causing the ball head rod 63 to push the locking block 61. At this time, the locking block 61 will gradually slide into the interior of the loudspeaker cover 4 and compress the return spring 62. At the same time, the locking block 61 will gradually move out of the interior of the positioning block 3. When the locking block 61 is completely removed from the interior of the positioning block 3, the loudspeaker cover 4 can be separated from the positioning block 3, so that the dust filter 5 can be disassembled to clean the dust on the dust filter 5.

[0039] After the loudspeaker cover 4 separates from the positioning block 3, the loudspeaker cover 4 will release the pressure on the L rod 73. At this time, the second reed 72 will push the baffle 71, so that the baffle 71 slides on the inner wall of the pager 1 and gradually covers the sound hole 2. When the two sets of baffles 71 are attached together, they will block the sound hole 2, preventing impurities from entering the interior of the sound hole 2 after the dustproof net 5 is removed, thereby protecting the equipment inside the pager 1.

[0040] As the loudspeaker cover 4 and the positioning block 3 gradually come together, the slope of the loudspeaker cover 4 will press the L rod 73 due to its trapezoidal structure, causing the L rod 73 to push the baffle 71. At this time, the baffle 71 will slide on the inner wall of the caller 1 and compress the second reed 72. As the baffle 71 slides, the sound hole 2 will gradually be exposed so that the sound hole 2 can make a sound.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
