Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of acupuncture needle collection devices, specifically relating to a medical acupuncture needle recycling counting and sensing device. Background Technology
[0002] Acupuncture, a traditional Chinese medicine therapy, uses metal needles to stimulate specific acupoints on the body to achieve the effects of unblocking meridians, regulating qi and blood, and strengthening the body's resistance to pathogens. After treatment, the doctor needs to carefully remove the acupuncture needles, handling 20 to 50 needles. To ensure safety, the doctor often needs to check twice to ensure that the number of acupuncture needles matches the actual number used. This process is not only time-consuming but also prone to errors, especially when there are many needles, as the chance of needle slippage leading to counting errors increases significantly.
[0003] Failure to remove acupuncture needles can lead to a range of discomforts, including pain, infection, nerve damage, and qi and blood deficiency. In some cases, the needle may even break, leaving a broken needle inside the patient's body and posing medical risks. This not only affects treatment effectiveness but also poses a potential threat to patient safety. Current technology lacks an effective counting and alerting mechanism for acupuncture needle retrieval, making it easy for needles to remain in the body.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, such as Figure 1-3 As shown, a medical acupuncture needle retrieval and counting sensor device includes a cylindrical body 1, which forms the main structure. The internal space of the cylindrical body 1 is rationally arranged, providing space to accommodate other components and facilitating portability and operation. The top of the cylindrical body 1 is equipped with a display screen 2, a power switch 3, and an adjustment button. The display screen 2 is an LCD screen that can display the number of retrieved acupuncture needles in real time. Through a clear interface, operators can quickly confirm the retrieval status, improving the efficiency of retrieval management and preventing omissions. The power switch 3 allows users to easily start and stop the device, and the adjustment button allows users to adjust the parameters displayed on the display screen 2 as needed.
[0024] The display screen 2 is located at the top center of the cylinder 1. A switch button 3 is located above the display screen 2, and an adjustment button is located below it. A needle insertion cylinder 7 is located on the side wall of the cylinder 1, allowing for easy insertion and storage of acupuncture needles. A battery compartment 9 is located at the bottom center of the cylinder 1, housing batteries for easy replacement and installation, providing power. A contact electrode 10 is located on the inner wall of the needle insertion cylinder 7. When an acupuncture needle is inserted into the needle insertion cylinder 7, the contact electrode 10 forms a pathway to sense the insertion. A spring plate 11 is connected to one side of the contact electrode 10 and is attached to the outer wall of the needle insertion cylinder 7. The spring plate 11 compresses the contact electrode 10 to contact the acupuncture needle, generating a trigger signal upon needle insertion and ensuring accurate counting.
[0025] The specific design of the aforementioned key components will be discussed in detail below:
[0026] The cylinder 1 is a hollow cylinder, providing space inside to support and accommodate other components. A number of needle inserters 7 are connected to the inner wall of the cylinder 1, arranged in a circular, layered, and upward-sloping manner around the center of the cylinder 1. This design effectively utilizes space for easy insertion and removal of acupuncture needles. Furthermore, the hollow design makes the device lightweight, convenient to operate and carry, and enhances its flexibility of use.
[0027] The control buttons include a triangle button 4 and a circular button 5. The triangle button 4 can be used to switch the display, and the circular button 5 can be used to confirm settings or reset. Through the clear and intuitive button design, users can quickly get started with the operation, improving the convenience of operation and the user experience.
[0028] The top edge of the cylinder 1 is provided with an anti-collision ring 6, which effectively prevents accidental collisions during use, protects internal components from damage, and improves the durability of the equipment. The bottom edge of the cylinder 1 is provided with a wear-resistant ring 8, which improves the wear resistance of the bottom of the equipment. Both the anti-collision ring 6 and the wear-resistant ring 8 are made of silicone.
[0029] The battery compartment 9 is equipped with a cover. The battery compartment 9 is used to hold batteries, and the cover can be easily opened for battery replacement when needed.
[0030] The contact electrodes 10 are arranged in pairs, with each pair facing each other. The number of spring plates 11 corresponds to the number of contact electrodes 10. The contact electrodes 10 are responsible for detecting the insertion of the needle. When the facing contact electrodes 10 contact the acupuncture needle, they form a pathway. The number of pathways is counted in real time to ensure accurate recording of the number of needles retrieved. In normal operation, the contact electrodes 10 are open circuits. A gap smaller than the diameter of the acupuncture needle is left between each pair of contact electrodes 10. When the acupuncture needle is inserted, it acts as a contact point to connect the open circuit and form a pathway. The spring plates 11 provide pressure to the contact electrodes 10, ensuring they adhere tightly to the contact electrodes.
[0031] The side wall of the needle insertion cylinder 7 is provided with an opening corresponding to the position of the contact electrode 10. The opening is used in conjunction with the contact electrode 10 to facilitate a certain degree of displacement of the contact electrode 10. It allows the contact electrode 10 to move slightly backward after the acupuncture needle is inserted so that it can make close contact with the acupuncture needle and hold the acupuncture needle tightly after it is inserted.
[0032] It also includes a control unit, which consists of a microcontroller (MCU) responsible for data processing. The microcontroller can receive signals from the contact electrodes 10 and count the number of pathways. A low-power microcontroller is selected to extend battery life. As mentioned earlier, the contact electrodes 10 are arranged in an opposing configuration inside the needle holder 7. When an acupuncture needle is inserted, the contact electrodes 10 form a circuit pathway, which transmits an electrical signal to the control unit upon connection. The display screen 2 is used to display the number of needles retrieved in real time. The display screen 2 is connected to the microcontroller and displays the changes in the count.
