The simultaneous application of vibration, pressure, and cold stimulation prevents or delays the transmission of pain signals to the brain, thereby reducing pain experienced by the patient during the injection.

Description

[0001] DESCRIPTION

[0002] MULTI-STIMULUS LOCAL ANESTHESIA ASSIST DEVICE

[0003] Technical Field

[0004] The present invention is a multi-stimulus anesthesia assist device developed for use in local anesthesia applications and aims to minimize pain. The said device is an anesthesia assist device that can simultaneously apply vibration, pressure, and cold stimuli to reduce pain during injections or other medical procedures.

[0005] State of the Art

[0006] Nowadays, the pain, anxiety, and discomfort experienced by adult and pediatric patients during local anesthesia applications pose a significant problem, especially for children and individuals sensitive to pain. Various techniques and devices have been developed to address this problem. Existing methods include separate devices that apply pressure, vibration, or cold stimuli to the injection site. However, most of these methods are insufficient to completely eliminate pain.

[0007] Currently used local anesthesia assist devices generally apply only vibration or cold stimuli to the skin in a linear fashion and with weak vibration. While these methods can provide some pain relief, they are insufficient to completely eliminate pain due to the weak vibration frequencies used and the linear distribution of the vibration. When vibration is not strong enough or when cold stimulus is applied alone, the pain signals transmitted to the nerve endings cannot be sufficiently suppressed, which fails to fully relieve patients' pain.

[0008] Another common method is needle-free anesthesia with compressed air pressure. This method aims to deliver the anesthetic agent to the tissue without an injection. However, this technique has some serious limitations. Needle-free anesthesia devices use sudden air pressure to administer the anesthetic agent. This creates a loud noise and pressure during operation of the device. This sudden noise and pressure can cause stress and anxiety in patients, making the anesthesia process more difficult. During the process of administering anesthesia with compressed air pressure, some patients may still experience pain. This pain is caused by the sudden and forceful application of pressure. Therefore, this method does not sufficiently reduce the pain experienced during local anesthesia.

[0009] The invention titled "A device for performing regional anesthesia" with the application number of 2020 / 13118 does not include features such as circular vibration and cold stimulus and therefore differs from the present invention.

[0010] Objective of the Invention

[0011] The objective of the present invention is to develop a device that can simultaneously apply vibration, pressure, and cold stimuli to minimize the pain experienced by patients during local anesthesia applications. It is designed to allow the user to easily operate it with one hand and includes powerful vibration motors built into it that can create a circular isolated injection area. In addition, the sensation of pain can be further reduced with an ice pack designed to protect the circular opening attached to the device for cold stimuli.

[0012] The stress and anxiety experienced by patients during medical procedures are often associated with the anticipation of pain. The present invention aims to reduce the stress experienced by patients before and during the procedure by making the anesthesia process less painful. Providing a painless or less painful experience, particularly for pediatric patients and adults with needle phobia, positively impacts the overall treatment process.

[0013] Finally, the objective of this invention is to improve the quality of the local anesthesia process in general. Unlike existing devices and methods, the present invention offers a multifaceted approach that better meets the needs of both medical personnel and patients. This, in turn, contributes to both improving clinical outcomes and increasing patient satisfaction.

[0016] 1. Circular Isolated Area, which is created by placing the vibration motors in a circular arrangement

[0017] 2. Ice Pack, which reduces pain and suffering by providing the application of cold stimuli

[0018] 3. Circular Opening, which provides a suitable area for conventional needle injections

[0019] Description of the Invention

[0020] One of the key features of the present invention is the ability to apply vibration in a circular pattern. The device features vibration motors arranged in a circular arrangement. This structure allows the vibrations to be concentrated within a circular isolated area (1). Circular vibration is evenly distributed across the skin surface, preventing or reducing the transmission of pain signals. Because vibration is carried through thick myelinated nerve fibers in the nervous system, it delays or suppresses pain signals from reaching the brain. This allows the patient to feel less pain during the injection.

[0021] The opening (3) in the center of the device provides a suitable area for conventional needle injections. When used in conjunction with the device's vibration motors and cold stimulus, this area minimizes pain during the injection. This same opening also allows the use of needle-free anesthesia devices. Needle-free anesthesia delivers the anesthetic agent subcutaneously using compressed air pressure. The present invention overcomes the disadvantages of needle-free anesthesia devices, such as high noise and sudden pressure, by combining vibration and cold stimulus. This reduces patient discomfort and makes the anesthesia process more comfortable.

[0022] The surface of the device that contacts the skin offers the possibility of applying cold stimulus as an additional stimulus. This surface is equipped with an ice pack (2), positioned to protect the opening in the center of the device. The cold stimulus reduces the sensitivity of nerve endings in the skin, thus reducing pain sensations. Cold stimulus also helps control inflammation and minimizes any swelling that may occur after the procedure. This feature is a key factor in increasing the effectiveness of the device in pain management.

[0023] The said device features user-controlled pressure applications. This pressure, combined with vibration motors, creates controlled pressure on the skin, making the transmission of pain signals more difficult. The device's ergonomic design features a circular opening for easy one-handed operation. This design allows medical personnel to comfortably hold the device and precisely target the application area. Furthermore, the device's user-friendly design improves the experience of both healthcare professionals and patients.

[0024] One of the most innovative aspects of this invention is the simultaneous application of vibration, pressure, and cold stimuli. These multiple stimuli simultaneously act on the skin surface and create a complex suppressive effect on the nervous system. Vibration interrupts the transmission of pain signals, while pressure helps further suppress them. Cold stimuli, on the other hand, reduce the sensitivity of nerve endings, making the perception of pain difficult. This combination significantly reduces the perceived pain of the injection and increases patient comfort.

[0025] The said device is equipped with a lithium-ion battery that powers the vibration motors. This battery ensures long-term and uninterrupted use of the device. Furthermore, thanks to its rechargeable structure, the device can be used repeatedly and keeps environmental impact to a minimum. This is a key feature that makes the device practical and economical.

[0026] The stress and anxiety experienced by patients during local anesthesia is often related to the anticipation of pain. The present invention aims to reduce the stress experienced by patients before and during the procedure by making the anesthesia process less painful. This offers a significant advantage, particularly for pediatric patients, individuals with needle phobia, and patients with generally low pain tolerance. A painless or less painful experience increases patient compliance with treatment and positively impacts the overall treatment process.

[0027] The present invention aims to offer a revolutionary solution in local anesthesia, meeting the needs of both patients and healthcare professionals. Unlike existing methods, the present invention offers a multifaceted approach and significantly improves the quality of the anesthesia process. This, in turn, contributes to improving clinical outcomes and increasing patient satisfaction.
