Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a portable transcranial electrical stimulator. Background Technology

[0002] Transcranial electrical stimulation (TES) is a non-invasive neuromodulation technique that uses low-intensity current to stimulate target areas of the cerebral cortex to regulate the excitability of cortical neurons, brain wave rhythms, promote neural remodeling and repair, and improve cerebral blood supply. It is a non-invasive neuromodulation technique that often uses instruments to apply current with specific parameters to the scalp surface to affect the excitability and function of brain regions. Therefore, TES devices are widely used in clinical and research fields.

[0003] In practical use, existing transcranial electrical stimulators come in both large and small sizes, but both have significant problems: 1. Due to the limited clinical area, large active devices not only occupy treatment room space but also make routine disinfection inconvenient; thus, the costly multi-integrated large devices are not suitable for small and medium-sized hospitals; 2. Existing small transcranial electrical stimulators often sacrifice functionality to reduce size, which not only reduces device availability but also makes them less portable.

[0004] Therefore, a portable transcranial electrical stimulator is proposed as a further improvement. Utility Model Content

[0045] A magnetic connection mechanism 5 is provided between the support frame 4 and the rear shell 3;

[0046] The magnetic connection mechanism 5 allows the support frame 4 to be retracted into the rear shell 3 when carried, making it easy to carry.

[0047] The front shell 1 and the rear shell 3 form an inner cavity for installing the circuit component assembly 2; so that circuit boards and electrical components with multiple functions can be installed in the inner cavity; making the size small and in a closed space, which facilitates disinfection and protection of the circuit component assembly 2 in the inner cavity.

[0048] The front shell 1 and the rear shell 3 are detachably connected. The connection method can be selected as: bolted post insertion positioning, which is fixedly connected by bolts, thus facilitating fixing and disassembly.

[0049] The circuit component assembly 2 is installed on the inner wall of the front shell 1 and the inner wall of the rear shell 3 respectively;

[0050] A battery compartment cover 31 is fixedly installed on the middle of the inner wall of the rear shell 3 away from the front shell 1. A battery 6 for power supply and maintaining the balance of the stimulator is clamped between the battery compartment cover 31 and the rear shell 3.

[0051] The battery compartment cover 31 is used to fix the battery 6 to the lower middle part of the rear shell 3 so that the center of gravity of the stimulator is low, so that it can be more stable and less likely to tip over when placed flat or supported by a support frame.

[0052] In the example: the length, width, and thickness of the stimulator are set to be 299.838*272.881*60.021mm respectively;

[0072] When the stimulator is laid flat, and the upper shell 41 of the support frame 4 is retracted into the U-shaped groove 32, the rubber plug and the anti-slip strip 100 on the rear shell 3 can play an anti-slip role.

[0073] If the support frame 4 is unfolded from the U-shaped groove 32, the anti-slip rubber strip 100 on the upper shell 41 of the support frame 4 and the anti-slip rubber strip 100 on the rear shell 3 can play an anti-slip role.

[0074] When the support frame 4 unfolds from the U-shaped groove 32, an angle is formed between the support frame 4 and the rear shell 3. In order to ensure the stability of the support, the angle between the support frame 4 and the rear shell 3 is set to be no more than 45°±1°.
