Description

Technical Field

[0001] This utility model relates to the field of medical call switch technology, and in particular to a portable medical call switch. Background Technology

[0002] In healthcare settings, portable medical call switches are crucial tools for ensuring patients receive timely medical assistance, especially suitable for hospitalized patients with limited mobility, post-operative recovery patients, and elderly individuals living at home. With the increasing demand for more refined medical services, higher requirements are being placed on the safety, durability, and portability of call switches. Traditional call switches often employ simple casing designs, only fulfilling basic calling functions. When faced with collisions, drops, and frequent disassembly and maintenance during daily use, they struggle to guarantee the stability of internal electronic components. Furthermore, some products lack convenient securing methods, making them prone to being dropped or lost during patient activity, leading to the failure of emergency calls and severely impacting the timeliness and reliability of medical services.

[0003] Existing medical call switches are mainly fixed types, usually consisting of a call panel in the ward, connecting lines, and a receiving device at the nurse station. The call panel is fixedly installed at the head of the bed or on the wall of the bathroom, and is connected to the call host at the nurse station via wires. When the patient presses the button on the call panel, the circuit is connected, and the indicator light and buzzer at the nurse station are activated to prompt medical staff to handle the situation.

[0004] However, while traditional fixed call switches can meet the calling needs around the hospital bed, patients lose their calling ability once they leave the fixed installation area, such as when going to the bathroom, engaging in rehabilitation activities, or moving around at home. This makes them unable to respond to sudden emergencies. Since fixed call switches cannot cover these areas, patients cannot send a help signal to medical staff or family members in time even if they encounter an emergency. Therefore, a portable medical call switch is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable medical call switch, which aims to improve the problem that the coverage area of ​​the existing fixed call switch is limited, and patients cannot send a help signal to medical staff or family members in a timely manner when they encounter an emergency outside the area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable medical call switch includes a caller, a protective shell on the outer wall of the caller, an adhesive strip fixedly connected inside the protective shell, the caller and the adhesive strip being in contact, a fixing block fixedly connected inside the protective shell, a support shaft rotatably connected inside the fixing block, a locking component on the outer wall of the support shaft, a connecting frame fixedly connected to the outer wall of the protective shell, and a portable component on one side of the connecting frame;

A spring is provided on one side of the locking rod. The two ends of the spring are fixedly connected to the locking rod and the support block, respectively.

[0009] As a further description of the above technical solution:

[0010] The portable component includes a connecting block and a hanging rope. One side of the connecting block is attached to one side of the connecting frame, and the hanging rope is fixedly connected to the other side of the connecting block.

[0011] As a further description of the above technical solution:

[0012] A limiting block is fixedly connected to one side of the connecting block, and the limiting block is slidably connected inside the connecting frame.

[0013] As a further description of the above technical solution:

[0014] A first support column is fixedly connected inside the connecting frame, and a second support column is fixedly connected inside the connecting frame.

[0015] As a further description of the above technical solution:

[0016] A slider is slidably connected to the outer wall of the first support column, and a locking block is slidably connected to the outer wall of the second support column. The limiting block is in contact with the slider and the locking block.

[0017] As a further description of the above technical solution:

[0018] Both sides of the slider are beveled, and one side of the card block is beveled while the other side is flat.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by fixing the call device inside the protective shell and using a lanyard design, the patient can carry the call switch with them. During this process, the lanyard structure drives the call device to move flexibly, enabling the patient to make a call at any time. This solves the problem that fixed call switches have limited coverage areas and patients cannot send help signals to medical staff or family members in time when encountering emergencies outside the area, thereby improving the portability of medical call switches.

[0025] 2. In this utility model, by pulling the lever, the locking block overcomes the elastic force of the third spring and slides, while the slider slides under the action of the second spring, thus realizing the disassembly of the connecting block. During installation, the limiting block pushes the slider and the locking block to slide, and after the spring returns to its original position, it locks the limiting block. These structures work together to achieve the effect of quick and convenient replacement of the hanging rope, solving the problem that the hanging rope is difficult to replace after it is fixed and cannot be flexibly adjusted according to the different usage habits, scenarios and damage of the hanging rope, thereby improving the flexibility of the medical call switch.

Detailed Implementation

[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 Figures 1-3 This utility model provides an embodiment of a portable medical call switch, including a caller 1, which is the core of the device and is responsible for actual signal transmission. It triggers a call signal through button sensing, ensuring that patients can easily send out a distress signal. A protective shell 2 is provided on the outer wall of the caller 1, and an adhesive strip 3 is fixedly connected inside the protective shell 2. The caller 1 and the adhesive strip 3 are in contact, which serves to buffer the caller 1 and prevent it from being damaged in violent collisions. A fixing block 4 is fixedly connected inside the protective shell 2, and a support shaft 5 is rotatably connected inside the fixing block 4. A locking component is provided on the outer wall of the support shaft 5. A connecting frame 10 is fixedly connected to the outer wall of the protective shell 2, and a portable component is provided on one side of the connecting frame 10.

[0035] The locking component includes a locking lever 6, which is rotatably connected to the outer wall of the support shaft 5. One side of the locking lever 6 is inclined, which can lock or release at a certain angle to ensure that the device is in a fixed state or can be freely adjusted. A support block 7 is fixedly connected inside the fixing block 4, and a push rod 8 is slidably connected inside the support block 7. One end of the push rod 8 is in contact with the locking lever 6. A spring 9 is provided on one side of the locking lever 6. The two ends of the spring 9 are fixedly connected to the inside of the locking lever 6 and the support block 7, respectively. The function of the spring 9 is to provide sufficient elasticity to maintain the stability of the locking lever 6, prevent it from loosening, and ensure the reliability of the caller 1. The portable component includes a connecting block 11 and a hanging rope 12. One side of the connecting block 11 fits against one side of the connecting frame 10, and the hanging rope 12 is fixedly connected to the other side of the connecting block 11. The hanging rope 12 allows the user to hang the caller 1 on their body, so that the patient can trigger the call signal at any time from any position.

[0036] Reference Figure 1 , Figure 4 and Figure 5A limiting block 19 is fixedly connected to one side of the connecting block 11. The limiting block 19 is slidably connected inside the connecting frame 10. A first support column 13 and a second support column 14 are fixedly connected inside the connecting frame 10. A slider 15 is slidably connected to the outer wall of the first support column 13, and a locking block 16 is slidably connected to the outer wall of the second support column 14. The limiting block 19 contacts the slider 15 and the locking block 16. Both sides of the slider 15 are inclined. The design of the inclined sides of the slider 15 ensures that the locking block 16 can maintain good contact with the limiting block 19 and move smoothly during operation. One side of the locking block 16... One side is inclined, and the other side is flat. The outer wall of the support column 13 is fitted with a spring 17, and the outer wall of the support column 14 is fitted with a spring 18. The two ends of the spring 17 are fixedly connected to the inside of the connecting frame 10 and the slider 15, respectively. The two ends of the spring 18 are fixedly connected to the inside of the connecting frame 10 and the locking block 16, respectively, to ensure that the slider 15 and the locking block 16 can automatically return to their original positions under a certain pressure when in use. A lever 20 is fixedly connected to one side of the locking block 16. The lever 20 is slidably connected to the inside of the connecting frame 10. Moving the lever 20 can drive the locking block 16 to move, thereby changing the fixed state of the hanging rope 12.

[0037] Working principle: When using this portable medical call switch, the caller 1, as the core component, is placed inside the protective shell 2. The rubber strip 3 inside the protective shell 2 contacts the caller 1. The rubber strip 3 is elastic and can act as a buffer to prevent the caller 1 from being damaged by collision or vibration inside the protective shell 2. At the same time, it can also fix the caller 1 to a certain extent and provide a relatively stable working environment for the caller 1. When it is necessary to install or remove the caller 1 into the protective shell 2, the caller 1 contacts the inclined surface of the locking rod 6, pushing the locking rod 6 to rotate around the support shaft 5 and compress the spring 9. Under the action of the spring 9, one end of the locking rod 6 will lock the caller 1, restricting its movement inside the protective shell 2. When removing, push the push rod 8 inside the support block 7, thereby releasing the locking rod 6 from locking the caller 1, which facilitates the installation and removal of the caller 1. At the same time, the hanging rope 12 makes it convenient for patients to hang the call switch on their body and make a call at any time.

[0038] When the hanging rope 12 needs to be replaced, pull the lever 20 on one side of the locking block 16. The lever 20 causes the locking block 16 to slide on the support column 14 against the elastic force of the spring 18. At the same time, the slider 15 will also slide under the action of the spring 17, so that the limiting block 19 is no longer obstructed. At this time, the connecting block 11 can be pulled out from the connecting frame 10 to remove the hanging rope 12. When the hanging rope 12 needs to be installed, insert the connecting block 11 into the connecting frame 10. During this process, the limiting block 19 pushes the slider 15 and the locking block 16. The inclined surface design on both sides of the slider 15 and one side of the locking block 16 allows them to overcome the elastic forces of the springs 17 and 18 respectively when pushed by the limiting block 19, and slide on the support column 13 and the support column 14. When the limiting block 19 slides past the slider 15 and the locking block 16, the second spring 17 and the third spring 18 return to their original positions, pushing the slider 15 and the locking block 16 to lock the limiting block 19, thereby firmly connecting the connecting block 11 to the connecting frame 10, realizing the installation of the hanging rope 12, and making it convenient to replace different types or damaged hanging ropes 12 according to actual needs.

[0039] 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.
