Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a portable automatic needle ejection device with a rotary sequential needle ejection mechanism. Background Technology

[0002] Acupuncture needles are the most important tool in acupuncture treatment. Currently, physicians or operators usually retrieve needles by hand from needle pouches, boxes, or tubes. This method has the following obvious drawbacks: ① Inconvenience in retrieval: Acupuncture needles are thin and smooth, especially when using disposable sterile needle sets. They need to be painstakingly pried out of plastic trays or packaging, which is inefficient and particularly inconvenient when continuous and rapid needle use is required; ② Hygiene risks: When retrieving needles by hand, fingers can easily touch the middle and rear of the needle, posing a risk of contaminating the needle and affecting aseptic technique; ③ Disorganized management: Needles are scattered, making it difficult to count them after use, which can easily lead to omissions or waste; ④ Psychological stress: For novices or patients, the process of manually handling needles may increase anxiety.

[0003] While some acupuncture auxiliary devices exist in existing technologies, they mostly focus on acupoint location or automatic needle insertion. These devices are complex, bulky, and expensive, failing to address the most fundamental and frequently encountered clinical challenge: how to conveniently, hygienically, and quickly dispense single acupuncture needles. Therefore, there is an urgent need for a sophisticated, easy-to-operate tool capable of automatically and sequentially dispensing acupuncture needles. To address this issue, this paper proposes a portable automatic acupuncture needle ejection device with a rotary table for sequential needle dispensing. Summary of the Invention

[0007] Furthermore, the anti-accidental touch mechanism includes a movable groove disposed on the side end of the needle outlet, a blocking block slidably installed inside the movable groove, sliding blocks disposed on both sides of the blocking block, a hinge hole installed on the side end of the sliding block, an adjusting disc rotatably installed on the cover, a first connecting rod rotatably connecting the eccentric position of the adjusting disc to the hinge hole at both ends, a locking groove disposed on the side end of the adjusting disc, a locking pin block slidably installed inside the locking groove, a second connecting rod rotatably connecting the eccentric position of the adjusting disc to the locking pin block at both ends, a locking pin hole disposed on the side end of the trigger button that matches the locking pin block, and a protective cover installed on the outside of the adjusting disc.

[0008] Furthermore, the movable groove is provided with sliding grooves on both sides that are adapted to the sliding block; the first connecting rod is rotatably installed with a connecting screw adapted to the hinge hole at the connection end with the hinge hole.

[0009] Furthermore, the manual dial includes a mounting base located in the middle of the bottom shell, an adjusting rod rotatably mounted inside the mounting base, adjusting handles and connecting protrusions located at both ends of the adjusting rod, and a ratchet mounted on the side of the connecting protrusion; the connecting protrusion is a square block, and a cylindrical groove is provided in the middle of the upper end of the connecting protrusion.

[0010] Furthermore, the locking mechanism includes a locking box located on the side of the mounting base, an adjusting rod rotatably installed inside the locking box, pawls and pressure plates located at both ends of the adjusting rod, a locking spring connecting the pressure plates and the locking box, a pressing rod slidably installed inside one of the through holes and in contact with the pressure plate, the pawl passing through the other through hole and being adapted to the ratchet; and the outer end of the pressing rod penetrating the bottom shell and connecting to the outside.

[0012] Furthermore, the lower end of the fixed base is provided with a cylinder that matches the cylindrical groove, the needle storage chamber is provided with a receiving groove that matches the large end of the acupuncture needle, a cylindrical slider is provided at the bottom of the receiving groove, and a second magnet block is provided in the middle of the cylindrical slider; the cylindrical slider is slidably installed inside the receiving groove; the size of the cylindrical slider matches the receiving groove.

[0013] Furthermore, the ratchet can simultaneously replace a needle reservoir aligned with the needle outlet with each rotation of one ratchet tooth, thus achieving the function of changing a needle reservoir with each rotation.

[0014] The beneficial effects of this invention are:

[0015] The beneficial effects of this invention are as follows:

[0016] 1) Achieves efficient and convenient single needle retrieval: Through the synergistic effect of the rotary needle storage and positioning drive mechanism, the operator can simply rotate the dial to sequentially switch the needle storage chambers, and can quickly and automatically eject a single acupuncture needle by triggering the button, which greatly simplifies the needle retrieval process and is especially suitable for clinical scenarios of continuous and rapid needle use, significantly improving the efficiency of acupuncture operation.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] See Figures 1 to 10 As shown, a portable automatic needle ejection device with rotary sequential needle ejection includes a rotary needle storage mechanism, a drive positioning mechanism, and a trigger control mechanism. The rotary needle storage mechanism includes a base shell 1, a needle outlet 2 located at the front end of the base shell 1, a disc-shaped needle plate 3 rotatably mounted within the internal cavity of the base shell 1, several needle storage chambers 4 on the needle plate 3, needles 5 installed inside the needle storage chambers 4, a detachable cover 6 mounted on the base shell 1, and a transparent observation window 7 on the cover 6. The drive positioning mechanism includes a manual dial 8 coaxially connected to the needle plate 3, and a locking mechanism 9 located on the side of the manual dial 8. The trigger control mechanism includes a trigger button 10 located in the middle of the cover 6, a needle pushing mechanism 11 located below the trigger button 10, and an anti-accidental activation mechanism 12 located on the side of the needle outlet 2. This invention provides an integrated and automated needle extraction tool with an overall architecture that achieves orderly needle storage through a rotary needle storage system, sequential selection through drive positioning, and single needle ejection through trigger control. The aim is to fundamentally change the traditional manual needle extraction method with a simple mechanical structure combination, achieving the basic goal of convenient, hygienic, and orderly needle extraction.

[0037] The push-pin mechanism 11 includes a mounting groove 111 on the cover 6, a trigger button 10 slidably mounted inside the mounting groove 111, a first rack 112 located at the lower end of the trigger button 10, a return spring 113 connecting the trigger button 10 and the cover 6, a fixed seat located inside the lower end of the mounting groove, a transmission rod 114 rotatably mounted inside the fixed seat, a first gear 115 and a second gear 116 mounted on the transmission rod 114, a guide groove mounted on the side end of the fixed seat, a push-out rod 117 slidably mounted inside the guide groove, a second rack located at the upper end of the push-out rod 117, a push-out arc block 118 mounted at the top of the push-out rod 117, and a first magnet block 119 located on the inner surface of the push-out arc block 118; the first gear 115 meshes with the first rack 112; and the second gear 116 meshes with the second rack. This provides an efficient, reliable, and reasonably lever-armed mechanical transmission scheme. The vertical action of pressing the button with a finger is converted into a horizontal push-pin action of the push-out rod 117 through the gear and rack mechanism, ensuring smooth operation and effective force transmission. The ejection arc block 118 and the first magnet block 119 are designed to engage with the cylindrical slider 42 and the second magnet block 43 sliding inside the receiving groove 41 in a non-contact adsorption manner, so as to achieve a gentle and precise ejection, avoid mechanical damage or slippage to the needle body, and improve the reliability of needle ejection and the protection of the needle.

[0038] The anti-accidental touch mechanism 12 includes a movable groove on the side of the needle outlet 2, a blocking block 121 slidably installed inside the movable groove, sliding blocks 122 on both sides of the blocking block 121, a hinge hole installed on the side of the sliding block 122, an adjusting plate 123 rotatably installed on the cover 6, a first connecting rod 124 rotatably connecting the eccentric position of the adjusting plate 123 to the hinge hole at both ends, a locking groove 125 on the side of the adjusting plate 123, a locking pin 126 slidably installed inside the locking groove 125, a second connecting rod 127 rotatably connecting the eccentric position of the adjusting plate 123 to the locking pin 126 at both ends, a locking pin hole 128 on the side of the trigger button 10 that matches the locking pin 126, and a protective cover 129 installed on the outside of the adjusting plate 123. When not in the needle-dispensing state, the blocking block 121 closes the needle outlet 2, preventing external contaminants from entering or the operator from accidentally touching the needle body to be dispensed. The locking pin 126, in conjunction with the trigger button 10, ensures that the trigger button 10 can only be pressed to dispense the needle when the blocking block 121 is open. This mechanical interlock design prevents the needle from being accidentally exposed before it is ready, ensuring operational safety.

[0039] The movable groove has sliding grooves on both sides that are adapted to the sliding block 122; this provides precise guidance for the sliding block, ensuring that the blocking block can smoothly and linearly perform opening and closing actions, avoiding jamming; the first connecting rod 124 is rotatably installed with a connecting screw adapted to the hinge hole at the connection end with the hinge hole. This ensures that the bottom shell 1 and the cover 6 can be disassembled and assembled.

[0040] The manual dial 8 includes a mounting base 81 located in the middle of the base shell 1, an adjusting rod 82 rotatably mounted inside the mounting base 81, adjusting handles 83 and connecting protrusions 84 located at both ends of the adjusting rod 82, and a ratchet 85 mounted on the side of the connecting protrusion 84. The connecting protrusion is a square block with a cylindrical groove in the middle of its upper end. This provides an ergonomic manual drive method with positioning feedback. The adjusting handle 83 facilitates force application and rotation. The square connecting protrusion 84 ensures reliable connection and synchronous rotation with the needle plate. The introduction of the ratchet structure is key; it works with the subsequent locking mechanism 9 to achieve unidirectional, step-by-step rotation. This allows each rotation of the ratchet to synchronously change the needle storage chamber and align it with the needle outlet 2. The ratchet mechanism emits a clear click and provides tactile feedback, ensuring that the operator can accurately and intuitively position the next needle, solving the problem of inaccurate positioning that may occur during rapid operation.

[0041] The locking mechanism 9 includes a locking box located on the side of the mounting base 81, an adjusting rod rotatably installed inside the locking box, pawls 91 and pressure plates 92 located at both ends of the adjusting rod, a locking spring 93 connecting the pressure plates 92 and the locking box, a pressing rod 94 slidably installed inside one of the through holes corresponding to the positions of the pawls and pressure plates on both sides of the locking box and in contact with the pressure plate, and the pawl 91 passing through another through hole to be adapted to the ratchet 85. The outer end of the pressing rod 94 passes through the bottom shell 1 and is connected to the outside. This mechanism enables unidirectional rotation positioning and quick release of the needle disc. Under the action of the locking spring 93, the pawl 91 engages with the ratchet tooth groove, preventing the needle disc from reversing and ensuring that the needle disc position is fixed and the needle is accurately dispensed. At the same time, the exposed pressing rod 94 presses down, driving the pawl 91 to disengage from the ratchet 85. At this time, the needle disc can rotate freely in the opposite direction, which facilitates quick reversal of the needle disc for needle loading, greatly improving the flexibility of operation and the efficiency of needle loading and resetting.

[0042] The locking mechanism 9 also includes a guide groove 95 located on the side of the locking box, a blocking rod 96 slidably installed inside the guide groove 95, a limiting plate 97 rotatably installed at the bottom of the base, a third connecting rod 98 rotatably connecting the blocking rod 96 and the limiting plate 97 at eccentric positions at both ends, and a fourth connecting rod 99 rotatably connecting the hinge hole on the side of the sliding block 122 and the limiting plate 97 at eccentric positions at both ends. This establishes a high-level linkage between the drive positioning mechanism and the anti-accidental touch mechanism; its core purpose is to achieve the intelligent safety logic of "positioning equals unlocking." When the manual dial rotates and positions the needle plate to a needle storage chamber 4, the limiting plate 97 and the linkage mechanism synchronously drive the blocking rod 96 in the anti-accidental touch mechanism to move, blocking the pawl 91 and preventing the ratchet 85 from rotating when the blocking block 121 is not open. This mechanical linkage ensures that it can only be triggered when the needle outlet 2 is open, fundamentally preventing needle dispensing failure or mechanism damage due to accidental touch, thus improving the intelligence and safety of the device.

[0043] The lower end of the fixed base is provided with a cylinder adapted to the cylindrical groove. The needle storage chamber 4 is provided with a receiving groove 41 adapted to the large end of the acupuncture needle 5. A cylindrical slider 42 is provided at the bottom of the receiving groove 41, and a second magnet block 43 is provided in the middle of the cylindrical slider 42. The cylindrical slider 42 is slidably installed inside the receiving groove 41. The size of the cylindrical slider 42 is adapted to the receiving groove 41. The assembly composed of the cylindrical slider 42 and the second magnet block 43 can use magnetic force to attract the needle tail, so that the acupuncture needle remains stable when stored in the needle plate and will not be scattered due to the movement or flipping of the device, thus ensuring the reliability of needle storage. At the same time, the assembly composed of the cylindrical slider 42 and the second magnet block 43 can perform non-contact adsorption with the ejection arc block 118 and the first magnet block 119 to achieve gentle and precise ejection of the acupuncture needle, avoiding mechanical damage or slippage to the needle body, improving the reliability of needle ejection and the protection of the needle.

[0044] The receiving groove 41 is provided with an anti-slip groove on its side end, and the cylindrical slider 42 is provided with an anti-slip slider that matches the anti-slip groove on its side end, so as to ensure that the cylindrical slider 42 will not fall off the receiving groove 41 after the needle is pushed out.

[0045] The needle storage compartment 4 is made of rigid plastic to prevent the first magnet block 119 and the second magnet block from being affected by the needle storage compartment 4 itself.

[0046] The adjustment lever 83 is equipped with a rotation direction indicator.

[0047] A locking groove is provided in the middle of the front side of the movable groove. A locking screw that is compatible with the locking groove is installed in the middle of the front side of the blocking block 121. A locking knob is threaded on the locking screw.

[0048] Example 2

[0049] The following are the specific steps for using a portable automatic needle ejection device with a rotary sequential needle ejection mechanism:

[0050] I. Preparatory Work

[0051] 1. Device inspection: Check whether the device casing is intact, whether the transparent observation window is clean, and confirm that the needle outlet is not blocked.

[0052] 2. Loading acupuncture needles:

[0053] ① Open the cover 6 to fully expose the needle plate.

[0054] ② Insert disposable sterile acupuncture needles (needle tips facing outward) into each needle storage chamber 4 in sequence, ensuring that the needle tail is magnetically fixed by the cylindrical slider 42 in the receiving groove 41;

[0055] ③ The loading quantity can be determined as needed, and can fill all needle storage compartments at most.

[0056] 3. Closing device: Close the cap 6. A "click" sound indicates that the cap 6 is locked. At this time, the status of the needle can be observed through the transparent window 7.

[0057] II. Basic Operating Procedures

[0058] Step 1: Unlock and Locate

[0059] Single needle sequence:

[0060] 1. Single-hand grip device, with the thumb or index finger placed on the adjustment handle 83 of the manual dial 8;

[0061] 2. Rotate the adjustment handle 83 clockwise (based on the rotation direction mark on the adjustment handle 83). A clear "click" sound indicates that the needle plate has rotated one notch, and one needle storage chamber 4 is aligned with the needle outlet 2.

[0062] 3. The ratchet mechanism automatically locks to prevent the needle disc from reversing.

[0063] Step 2: Needle withdrawal operation

[0064] 1. Trigger Preparation: Align the needle outlet 2 of the device with the area above the treatment zone; open the blocking block 121; release the lock on the trigger button 10.

[0065] 2. Press the button: Press the trigger button 10 in the middle of the cover with your index finger. The needle push mechanism 11 is activated. The push rod 117 pushes the acupuncture needle 5 out of the needle outlet and smoothly ejects about 2 / 3 of the needle body length for easy clamping.

[0066] 3. Picking up the acupuncture needle: Use needle pliers or your fingers to pinch the exposed needle handle and gently remove it for use.

[0067] Step 3: Reset and Continuous Use

[0068] ①After needle removal: Release the trigger button 10. Under the action of the reset spring 113, the needle pushing mechanism 11 retracts and pushes the blocking block to reset and close the needle outlet 2;

[0069] ② To use the next needle: Simply repeat step 1 and rotate the dial to the next position to prepare to use the next acupuncture needle.

[0070] III. Special Operations

[0071] 1. Quick reset (skip empty positions or return to the starting point)

[0072] ① Locate the pressing lever 84 on the side of the device;

[0073] ② Press this lever with your thumb while simultaneously rotating the manual dial 8 counterclockwise with your other hand;

[0074] ③ At this point, the pawl 91 disengages from the ratchet 85, and the needle plate can rotate freely in the opposite direction;

[0075] ④ Rotate the needle plate to the desired position (such as the starting point or skipping the used needle magazine), release the press lever, and the pawl will relock the ratchet.

[0076] 2. Needle loading techniques

[0077] ① After opening the cap 6, you can load the disposable acupuncture needles (usually 20 needles per pack) into the needle storage compartment of the needle plate and align them.

[0078] ②Using the magnetic attraction of the cylindrical slider 42, the acupuncture needle 5 can be quickly loaded into the corresponding needle storage chamber 4.

[0079] 3. Stopping midway and carrying

[0080] ① During any non-use period, the anti-accidental contact mechanism keeps the needle outlet 2 closed.

[0081] ② Before carrying, ensure that the trigger button 10 is not pressed.

[0082] ③ The magnetic fixing design inside the device ensures that the needles will not fall apart during movement.
