Description

TECHNICAL FIELD

[0002] As an invasive treatment method, acupuncture inevitably causes pain to patients. During acupuncture treatment, the pain caused by skin penetration is the main source of pain in the process of acupuncture treatment, because the subcutaneous nerve and blood vessel distribution is extremely rich. The proficiency of needle insertion technique and the stability of operation determine the degree of skin penetration pain in clinic. Obvious skin penetration pain not only increases the fear of needle in patients, but also often affects the curative effect of acupuncture. In order to reduce the pain accompanied by needle insertion, many cases in previous studies have tried to provide a quick and stable ejection needle insertion device. By analyzing a large number of domestic patents related to ejection needle insertion device, it is found that the existing technology has a complex structure of ejection box. In order to prevent the inconsistency of each force during manual needle insertion from causing the depth of needle insertion to be deep or shallow, a motor driven method is used for needle insertion, which leads to high production cost. Moreover, if the circuit fails, it will affect the safety of acupuncture, and the stability is poor. The ejection needle insertion process is complicated and prone to failure.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below in combination with the drawings.

[0035] As Figures 1-8As shown, the first aspect of the present application provides a manual ejection box for ejecting acupuncture needles in an acupuncture needle box, which comprises a third sleeve 300, a second sleeve 200, a first sleeve 100, a third elastic member 310 is arranged in the third sleeve 300, the second sleeve 200 is inserted into the third sleeve 300, the third sleeve 300 is arranged to be movable relative to the second sleeve 200, the inner side of the second sleeve 200 close to the first sleeve 100 abuts against the third elastic member 310, the end of the second sleeve 200 is connected with an ejection rod 210, the side of the second sleeve 200 is provided with a second window 220, the first sleeve 100 is sleeved on the second sleeve 200, the second sleeve 200 is arranged to be movable relative to the first sleeve 100, the ejection rod 210 penetrates through the first sleeve 100, a first elastic member 110 is arranged in the first sleeve 100, the first elastic member 110 is arranged along the direction of the first sleeve 100, one end of the first elastic member 110 abuts against the inner wall of the first sleeve 100, and the other end abuts against the end of the second sleeve 200, the side of the first sleeve 100 is provided with a clamping structure 130, the clamping structure 130 can elastically deform outward along the side of the first sleeve 100, and the clamping structure 130 is slidably arranged in the second window 220, wherein the elastic coefficient of the first elastic member 110 is greater than that of the third elastic member 310.

[0036] The clamping structure 130 is clamped with the end of the second window 220, and the clamping structure 130 can elastically deform outward along the side of the first sleeve 100 under the action of an external force to release the clamping with the end of the second window 220.

[0037] As shown, Figures 3-7 The ejection box has an ejection box extension direction A1, the third sleeve 300 is first pressed to move the third sleeve 300 to the A1 direction, thereby driving the second sleeve 200 to move to the A1 direction, in the process of moving, as Figure 4As shown, due to the clamping of the clamping structure 130 and the second window 220, the second window 220 cannot continue to move in the A1 direction, and the third sleeve 300 can continue to move in the A1 direction. Since the second sleeve 200 abuts against the third elastic member 310 near the inner side of the first sleeve 100, the third sleeve 300 will compress the third elastic member 310 in the third sleeve 300 together with the second sleeve 200 during the continuous movement of the third sleeve 300 in the A1 direction. When the clamping structure 130 is disengaged, the third elastic member 310 releases the elastic potential energy, causing the second sleeve 200 to be ejected in the A1 direction, driving the ejection rod 210 to be ejected in the A1 direction, pushing the acupuncture needle in the needle hole 520 to be ejected, and ejecting the acupuncture needle in the needle box. When the third elastic member 310 releases the elastic potential energy, the second sleeve 200 is ejected in the A1 direction, compressing the first elastic member 110. The first elastic member 110 functions to reset the second elastic member after the manual ejection box completes the ejection. At this time, the second sleeve 200 is subjected to the elastic force from the first elastic member 110 and the elastic force from the third elastic member 310, which are in opposite directions. The first elastic member 110 needs to overcome the elastic force of the third elastic member 310 during the process of resetting the second sleeve 200 to its original state, so the elastic coefficient of the first elastic member 110 needs to be greater than that of the third elastic member 310 to reset the second sleeve 200.

[0038] The clamping structure 130 is clamped with the end of the second window 220, and the clamping structure 130 can be elastically deformed outward along the side of the first sleeve 100 under the action of an external force to disengage the end of the second window 220.

[0039] As shown in Figures 1-8 The third sleeve 300 is connected with the pressing device 400, which can push the third sleeve 300 to move towards the second sleeve 200 to compress the third elastic member 310. The pressing device 400 can facilitate the doctor to push the third sleeve 300 through the pressing device 400, as shown in Figure 8 The pressing device 400 is connected with the third sleeve 300, and the end of the pressing device 400 is manually pressed, so that the third sleeve 300 is pushed by the pressing device 400 to move towards the second sleeve 200 to compress the third elastic member 310.

[0040] As shown in Figures 1-8As shown, the pressing device 400 includes a fixed part 410 connected with the third sleeve 300 and an adjusting part 420 penetrating the fixed part 410 and abutting against the third elastic member 310. The adjusting part 420 enables the pressing device 400 to have an adjustable pressure. The adjusting part 420 penetrates the fixed part 410 and abuts against the third elastic member 310. By adjusting the depth of the adjusting part 420 penetrating the fixed part 410, the third elastic member 310 can be compressed. If the depth of the adjusting part 420 penetrating the fixed part 410 is increased, the adjusting part 420 moves towards the third sleeve 300. In this way, when the pressing device 400 is not pressed, the third elastic member 310 has been compressed. When the third elastic member 310 is released, the third elastic member 310 stores more elastic potential energy, which can be released to accelerate the ejecting rod 210 at a greater acceleration, and finally eject the acupuncture needle at a greater speed. The doctor can adjust the adjusting part 420 to increase or decrease the speed of the acupuncture needle according to the actual acupuncture treatment needs.

[0041] It should be noted that in actual design, when the adjusting part 420 penetrates the fixed part 410 to the maximum depth, the third elastic member 310 has been compressed to the maximum extent. The speed of the acupuncture needle when the acupuncture needle is ejected reaches the maximum value of the speed of the acupuncture needle ejected by the manual ejecting box. The speed of the acupuncture needle cannot be too large, because when the speed of the acupuncture needle is too large, the depth of the acupuncture needle when the acupuncture needle is ejected into the human skin will be too deep, which may cause damage to the patient's subcutaneous organs and cause danger. For example, the depth of the acupuncture needle is greater than 10 mm. Therefore, the maximum depth of the adjusting part 420 penetrating the fixed part 410 should be reasonably set. When the depth of the adjusting part 420 penetrating the fixed part 410 reaches the maximum value, the speed of the acupuncture needle and the depth of the acupuncture needle are still within a safe range.

[0042] The adjusting part 420 is arranged to be movable relative to the fixed part 410. The adjusting part 420 can be fixed with the fixed part 410 at a fixed position to prevent the third elastic member 310 from ejecting the adjusting part 420 from the fixed part 410. When the adjusting part 420 penetrates the fixed part 410 to compress the third elastic member 310, the third elastic member 310 has elastic potential energy due to compression, which can generate a pushing force on the adjusting part 420. The adjusting part 420 is connected with the fixed part 410 to ensure that after the depth of the adjusting part 420 penetrating the fixed part 410 is adjusted, the adjusting part 420 will not be moved by the third elastic member 310, so as not to affect the adjusting effect.

[0043] The adjusting part 420 comprises an adjusting screw 421, and a thread is arranged in the fixing part 410 and matched with the adjusting screw 421. The adjusting screw 421 is screwed into the fixing part 410 and abuts against the third elastic member 310. By adjusting the depth of the adjusting screw 421 screwed into the fixing part 410, the third elastic member 310 can be compressed, so as to adjust the ejection pressure of the third elastic member 310 when the acupuncture needle is ejected, and adjust the ejection speed of the acupuncture needle. The screw and thread matched mode can be used to finely adjust the pressure. The adjusting screw 421 can be slightly rotated to finely adjust the compression degree of the third elastic member 310, so as to finely adjust the ejection speed of the acupuncture needle. In other embodiments, the fixing part 410 can be provided with equidistant clamping structures 130, and the adjusting part 420 is clamped with the clamping structures 130. In this way, the compression degree of the third elastic member 310 can be adjusted step by step, so as to adjust the ejection speed of the acupuncture needle step by step.

[0044] As shown in Figures 2-7 The adjusting screw 421 is provided with an adjusting plate 422 at one end penetrating the fixing part 410. The adjusting plate 422 abuts against the third elastic member 310. When the adjusting screw 421 is rotated, the adjusting plate 422 is also moved. The adjusting plate 422 abuts against the third elastic member 310, so that the movement of the adjusting plate 422 can compress the third elastic member 310. The one end of the adjusting screw 421 penetrating the fixing part 410 is connected with a fixing rod 423. The fixing rod 423 penetrates the adjusting plate 422 and is inserted into the third elastic member 310 to fix the shape of the third elastic member 310, so as to avoid that the third elastic member 310 is compressed and deviated to one side. The fixing rod 423 is inserted into the middle of the third elastic member 310 to fix the third elastic member 310. When the third elastic member 310 is compressed, the third elastic member 310 is easily deviated to one side due to the extrusion force. In this way, when the elastic potential energy is released, the direction of the force applied to the acupuncture needle is also deviated to one side. The direction of the acupuncture needle ejected can be affected, the stability of the acupuncture needle ejected is affected, and the stability of the acupuncture needle ejected is affected. Therefore, the fixing rod 423 is arranged to penetrate the adjusting plate 422 and be inserted into the third elastic member 310, so as to fix the shape of the third elastic member 310 and play a guiding role when the third elastic member 310 is compressed.

[0045] It should be noted that the length of the fixing rod 423 cannot be too long. During the process that the third sleeve 300 is moved to the second sleeve 200 direction to compress the third elastic member 310, the inner wall of the second sleeve 200 can not be able to continue to move and compress the third elastic member 310 due to the end of the fixing rod 423.

[0046] As shown in Figure 8As shown, the end of the adjusting screw 421 away from the fixed part 410 is provided with a screw cap 424, the surface of the screw cap 424 is provided with anti-skid lines 425, the screw cap 424 is convenient for the user to hold, the screw cap 424 is twisted to drive the adjusting screw 421 to screw into the fixed part 410, the surface of the screw cap 424 is provided with uneven lines, when the user twists the screw cap 424, the anti-skid lines 425 on the surface can increase the friction between the skin of the user and the surface of the screw cap 424, so that the user can more easily twist the screw cap 424 to adjust the screwing depth of the adjusting screw 421.

[0047] The length of the first elastic member 110 when not compressed is greater than the distance between the second window 220 and the end of the third sleeve 300, and the length of the first elastic member 110 when not compressed is greater than the distance from the edge of the second window 220 close to the third sleeve 300 to the end of the third sleeve 300 close to the second window 220, so as to avoid that the first elastic member 110 is too short to cause the clamping structure 130 to be still located between the second window 220 and the third sleeve 300 after reset, and the clamping structure 130 cannot be reset to the position capable of being clamped with the edge of the second window 220 after ejection, thereby affecting the next ejection.

[0048] As shown in Figure 1 and Figures 3-8 The clamping structure 130 is provided with a strip-shaped slot 120 on each side, the clamping structure 130 includes a clamping concave part 131 and a clamping convex part 132, the clamping concave part 131 and the clamping convex part 132 are fixedly connected, the clamping concave part 131 is slidingly arranged in the second window 220, and is clamped and locked with the end of the second window 220 when sliding to the end of the second window 220, thereby limiting the second sleeve 200 from moving towards the first sleeve 100, and the clamping convex part 132 is outwardly inclined. The strip-shaped slot 120 enables the clamping structure 130 to move inwardly or outwardly on the side of the first sleeve 100, the clamping concave part 131 is inwardly recessed, and when sliding to the end of the second window 220, the inwardly recessed clamping concave part 131 contacts the end of the second window 220, thereby clamping the second window 220, so that the second sleeve 200 cannot continue to move in the A1 direction.

[0049] It should be noted that the length of the strip-shaped slot 120 affects the difficulty of the clamping structure 130 moving inwardly or outwardly on the side of the first sleeve 100, when the strip-shaped slot 120 is relatively short, that is, the distance from the clamping structure 130 to the end of the strip-shaped slot 120 is relatively short, the moment arm is relatively short, and the clamping structure 130 is not easy to deform, so a larger force needs to be applied to the clamping structure 130 to move the clamping structure 130, and vice versa, when the strip-shaped slot 120 is relatively long, the clamping structure 130 is easy to deform, and a smaller force can move the clamping structure 130 inwardly or outwardly.

[0050] When the engaging protrusion 132 slides to the edge of the end of the third sleeve 300 near the second sleeve 200, the edge of the end of the third sleeve 300 can push the engaging protrusion 132 outward along the engaging protrusion 132, thereby driving the engaging recess 131 to release its engagement and leave the second window 220, thereby unlocking the second sleeve 200. Because the engaging protrusion 132 and the engaging recess 131 are fixedly connected, when the engaging protrusion 132 is pushed outward by the end of the third sleeve 300, the engaging recess 131 is also driven to move outward, causing the engaging recess 131 to leave the second window 220 and release its engagement and lock. At this time, the compressed third elastic member 310 releases its elastic potential energy, causing the second sleeve 200 to move in the direction A1, pushing the ejection rod 210 to eject.

[0051] The engaging protrusion 132 is inclined outwards and plays a guiding role when contacting the end edge of the third sleeve 300, so that the end edge of the third sleeve 300 can push the engaging protrusion 132 outwards.

[0052] like Figures 1-8 As shown, a third window 320 is formed on the side of the third sleeve 300. The second sleeve 200 is inserted into one end of the third sleeve 300 and provided with a limiting structure 230. The limiting structure 230 engages with the third window 320. The limiting structure 230 prevents the second sleeve 200 from being ejected from the second sleeve 200 and separating from the third sleeve 300 during the ejection process.

[0053] The limiting structure 230 protrudes outward and engages with the edge of the third window 320. The outward protrusion and engagement with the edge of the third window 320 simplify the structure of the limiting structure 230 and facilitate manufacturing. In other embodiments, the limiting structure 230 can also be set on the third window 320 and recessed inward to engage the second sleeve 200 for positioning.

[0054] According to a second aspect of the present invention, an acupuncture needle box is provided for cooperating with an ejection box, comprising a box body 500, wherein the first direction is parallel to the extension direction A1 of the ejection box, the box body 500 comprises a needle clamping cavity 510 and a push needle through hole 520 connected to the needle clamping cavity 510, the push needle through hole 520 is arranged in the extension direction of the ejection rod 210, the push needle through hole 520 is aligned with the ejection rod 210, the push needle through hole 520 is used to place the acupuncture needle to be launched, the push needle through hole 520 is formed with a pin hole 521 and a needle outlet hole 522 on the box body 500 along the first direction; the acupuncture needle is ejected from the needle outlet hole 522 after being subjected to an external force at one end thereof; the external force is applied through the pin hole 521, a plurality of placement positions for placing the acupuncture needles are arranged in sequence in the needle clamping cavity 510, at least one of the plurality of placement positions is adjacent to the push needle through hole 520, and the acupuncture needle in at least one of the plurality of placement positions can be moved into the push needle through hole 520.

[0055] The acupuncture needle box can be placed on a support surface 530 and can accommodate multiple acupuncture needles. As shown in Figures 3-8 The box body 500 includes a needle clamping cavity 510 and a needle pushing through hole 520 communicating with the needle clamping cavity 510. The needle pushing through hole 520 penetrates through both ends of the box body 500 in the extension direction thereof and forms a needle tip hole 521 and a needle outlet hole 522 at both ends thereof, respectively. The needle clamping cavity 510 includes a bottom surface 511 placed parallel to the support surface 530 and communicating with the needle pushing through hole 520. The acupuncture needles can be arranged in the needle pushing through hole 520.

[0056] The needle clamping cavity 510 has the bottom surface 511, and multiple placement positions are arranged in sequence and side by side on the bottom surface 511 and parallel to the first direction.

[0057] The box body 500 includes an elastic element 600, which continuously applies an elastic force to the acupuncture needles arranged in sequence in the needle clamping cavity 510, so that the acupuncture needles can move or have a tendency to move towards the needle pushing through hole 520.

The box body 500 has a needle insertion end 550 at one end of the needle outlet hole 522. The needle clamping cavity 510 includes a bottom surface 511 for accommodating the acupuncture needles, and the acupuncture needles are located in the needle pushing through hole 520. The bottom surface 511 is parallel to the support surface 530. The acupuncture needles are launched from the needle outlet hole 522 after being subjected to an external force at one end thereof; the external force is applied to the acupuncture needles through the needle tip hole 521.

[0059] The above-mentioned acupuncture needle box can be sterilized after being loaded with acupuncture needles, for example, by ethylene oxide gas sterilization, after being placed in a sterilization bag. In use, the sterilization bag is opened, the acupuncture needle box is taken out, and the acupuncture needle box is assembled in a launching box, and then the acupuncture needle box can be used.

[0060] Preferably, an elastic element 600, specifically a spring, is further included. The spring continuously applies an elastic force to the acupuncture needles in the needle clamping cavity 510 to move the acupuncture needles in the direction of the needle pushing through hole 520, or makes the acupuncture needles have a tendency to move in the direction of the needle pushing through hole 520. This facilitates the movement of the acupuncture needles in the direction of the needle pushing through hole 520, so that when the acupuncture needle in the needle pushing through hole 520 is launched, other acupuncture needles can continuously fill the position of the acupuncture needle to be launched in the needle pushing through hole 520.

[0061] The box body 500 comprises a plug-in end 540 and a needle piercing end 550; the top needle hole 521 is arranged on the plug-in end 540, and the needle outlet hole 522 is arranged on the needle piercing end 550; the box body 500 further comprises a needle piercing head 560, the needle piercing head 560 is connected to the needle piercing end 550, and an inner hole 561 arranged in the needle piercing head 560 is in communication with the needle pushing hole 520 through the needle outlet hole 522, and the inner hole 561 is arranged in the extension direction of the needle pushing hole 520.

[0062] Preferably, as shown in the drawings, the acupuncture needle box further comprises a needle piercing head 560. The needle piercing head 560 is connected to the needle piercing end 550. An inner hole 561 is formed in the needle piercing head 560 and is in communication with the needle pushing hole 520. The inner hole 561 is arranged in the extension direction of the needle pushing hole 520. Thus, when the needle tip of the acupuncture needle is pierced out of the inner hole 561, better guidance can be provided for the needle tip, and the need for needle piercing at various angles can be ensured. Figures 3-8

[0063] As shown in the drawings, the inner wall of the first sleeve 100 is provided with an ejection hole 140, and the ejection rod 210 extends outwardly through the ejection hole 140. The ejection hole 140 plays a guiding role, so that the ejection rod 210 can only be ejected along the extension direction corresponding to the ejection hole 140, thereby ensuring that the ejection rod 210 can be aligned with the needle pushing hole 520. Figure 2 The ejection hole 140 is arranged in the extension direction of the needle pushing hole 520, and the ejection rod 210 is aligned with the needle pushing hole 520. The ejection rod 210 can only eject the acupuncture needle to be launched in the needle pushing hole 520 when the ejection rod 210 is aligned with the needle pushing hole 520.

[0064] According to a third aspect of the present application, an acupuncture needle insertion device is provided, which comprises the manual ejection box of the first aspect of the present application and the acupuncture needle box of the second aspect of the present application, the acupuncture needle box is used in cooperation with the manual ejection box, and the acupuncture needle box comprises a box body 500, the box body 500 comprises a needle clamping cavity 510 and a needle pushing hole 520 in communication with the needle clamping cavity 510; the needle pushing hole 520 is arranged in the extension direction of the ejection rod 210, the needle pushing hole 520 is aligned with the ejection rod 210, and the needle pushing hole 520 is used for placing the acupuncture needle to be launched;

[0065] The needle pushing hole 520 is formed with a top needle hole 521 and a needle outlet hole 522 on the box body 500 in a first direction; the acupuncture needle is ejected from the needle outlet hole 522 after the acupuncture needle is subjected to an external force at one end thereof; and the external force is applied through the top needle hole 521;

[0066]

[0067] ​​The needle clip cavity 510 has a plurality of needle placement positions for placing acupuncture needles in sequence, at least one of the plurality of needle placement positions is adjacent to the needle pushing through hole 520, and the acupuncture needle in at least one of the plurality of needle placement positions can be moved into the needle pushing through hole 520. The acupuncture needle box is installed at the end of the manual ejection box box body 500, and the thimble hole 521 of the acupuncture needle box corresponds to the ejection rod 210 of the manual ejection box. The ejection rod 210 enters the thimble hole 521 to apply force to the acupuncture needle.

[0068] The working process of the present application is: the acupuncture needle box is installed on the manual ejection box, the thimble hole 521 of the acupuncture needle box is aligned with the ejection rod 210 of the manual ejection box, the ejection rod 210 enters the acupuncture needle box from the thimble hole 521, the initial state is as shown in Figure 3 Then press the third sleeve 300 or drive the third sleeve 300 to move towards the second sleeve 200 by pressing the pressing device 400. After pressing, the third sleeve 300 moves towards the second sleeve 200, which also pushes the second sleeve 200 to move towards the first sleeve 100. Since the second sleeve 200 moves and the first sleeve 100 is fixed in position, the second sleeve 200 will move to the position where the clamping structure 130 is clamped with the edge of the second window 220, as shown in Figure 4 When the clamping structure 130 is clamped with the edge of the second window 220, the second sleeve 200 cannot continue to move towards the first sleeve 100, but the third sleeve 300 can continue to move towards the second sleeve 200. Since the inner side of the second sleeve 200 close to the first sleeve 100 abuts against the third elastic member 310, the third sleeve 300 will compress the third elastic member 310 in the third sleeve 300 during the process of continuing to move towards the second sleeve 200, as shown in Figure 5 The third sleeve 300 will continue to move to the position where it contacts the clamping structure 130. When the third sleeve 300 contacts the clamping structure 130, the end of the third sleeve 300 that contacts the clamping structure 130 will push the clamping structure 130 outward, so that the clamping structure 130 is disengaged from the clamping of the edge of the second window 220, as shown in Figure 6As shown, after the clamping structure 130 is released from clamping the edge of the second window 220, the compressed third elastic member 310 releases the elastic potential energy and propels the second sleeve 200 and the ejection rod 210 on the second sleeve 200 in the direction of the first sleeve 100. The ejection rod 210 enters the needle hole 521 and exerts a pushing force on the acupuncture needle to accelerate the ejection of the acupuncture needle. Since the second sleeve 200 also moves in the direction of the first sleeve 100 during ejection, the second sleeve 200 and the second sleeve 200 compress the first elastic member 110 during ejection. After ejection, the first elastic member 110 releases the elastic potential energy and pushes the second sleeve 200 to reset the second sleeve 200 and the ejection rod 210. The second sleeve 200 pushes the third sleeve 300 to reset, as shown in FIG. 6. Figure 7 As shown, after the first elastic member 110 releases the ejection potential energy to reset the second sleeve 200, the elastic rod, and the third sleeve 300, the manual ejection box returns to its original state. The distance of compression of the third elastic member 310 is the same each time the button is pressed, so the ejection force on the acupuncture needle is also the same. The acupuncture needle can be ejected with a stable pressure to ensure consistent needle insertion depth each time. The elastic force of the third elastic member 310 when released can be adjusted by the adjustment portion 420 to achieve different needle insertion speeds, making it convenient for doctors to perform acupuncture treatment on patients and reducing the pain felt by patients during acupuncture treatment. The safety is high. Compared with the automatic needle insertion device, the manual needle insertion method avoids circuit failure and does not use electronic components, so the structure is simple, the production cost is low, the stability is good, the ejection process is simple, and faults are less likely to occur.

[0069] The above only describes some embodiments of the present application. Those skilled in the art can make several modifications and improvements without departing from the inventive concept, and these are within the scope of the present application.
