Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to an easily positioned acupuncture needle tube. Background Technology
[0002] Acupuncture is a general term for needling and moxibustion. Needling refers to inserting needles (usually filiform needles) into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, and using needling techniques such as twisting and lifting to stimulate specific parts of the body to achieve the purpose of treating diseases.
[0003] A needle insertion tube is an auxiliary tool for acupuncture. It is a small round tube made of metal or plastic that can avoid pain during needle insertion. Acupuncture needles can pass through the needle insertion tube. The tube is slightly shorter than the selected acupuncture needle. During acupuncture, the left hand presses the needle insertion tube on the acupoint, and the right hand flicks the exposed needle tail inside the tube to quickly insert the needle into the skin. Then the tube is removed and the needle is manipulated. Using a needle insertion tube can avoid pain during needle insertion.
[0004] However, conventional needle tubes are usually of a fixed length. During acupuncture, the depth of needle insertion needs to be changed according to the treatment requirements. Conventional needle tubes cannot be used for different insertion depths, and their applicability is low. At this time, users need to frequently select needle tubes of different lengths according to different insertion depths, which is cumbersome and has obvious shortcomings. Utility Model Content
[0005] To reduce the need for frequent needle replacements during acupuncture and improve the applicability of the needle, this application provides an easily locatable acupuncture needle.
[0006] The acupuncture needle insertion tube that is easy to position, as provided in this application, adopts the following technical solution:
[0007] An easily positioned acupuncture needle insertion tube includes a needle insertion tube, the end of which is provided with a threaded sleeve, and an adjustment tube is internally threaded to the threaded sleeve.
[0008] By adopting the above technical solution, when it is necessary to change the acupuncture depth, the user first inserts the acupuncture needle into the needle tube, and then rotates the adjusting tube. With the threaded engagement of the threaded sleeve and the adjusting tube, the adjusting tube will move upward along the threaded sleeve during rotation. When the adjusting tube moves to meet the acupuncture depth requirement, the user presses the acupuncture needle until the finger abuts against the end face of the adjusting tube, thereby completing the acupuncture. The setting of the threaded sleeve and the adjusting tube realizes the automatic adjustment of the length of the needle tube. When changing the acupuncture depth, the user does not need to change to a different needle tube, thus improving the applicability of the needle tube.
[0009] Optionally, a support block is provided at the end of the regulating tube. The support block is frustum-shaped and has a through hole communicating with the needle hole of the needle tube. The diameter of the support block away from the end of the regulating tube is larger than the diameter near the end of the regulating tube.
[0010] By adopting the above technical solution, before inserting the needle, the user places the larger end face of the support block against the needle insertion site of the recipient. At this time, the support block can increase the contact area between the needle tube and the human body, making the needle tube more stable on the skin and reducing the needle insertion deviation caused by the shaking of the needle tube, thereby further improving the applicability of the needle tube.
[0011] Optionally, the support block is made of a transparent material.
[0012] By adopting the above technical solution, during the acupuncture operation, the user can clearly observe the initial state of the acupuncture needle in contact with the skin and the subtle changes of the acupuncture needle on the skin surface when it is inserted, such as whether there is bleeding or whether the acupuncture needle is bent or other abnormal conditions, so as to make timely adjustments and further ensure the safety and accuracy of acupuncture treatment.
[0013] Optionally, a guide sleeve is provided on the outer surface of the needle tube, and a support hole for the needle to pass through is opened at the end of the guide sleeve away from the adjustment tube. Guide grooves are opened on the inner sidewalls of the guide sleeve, and a guide block is provided on the outer surface of the needle tube to slide with the guide groove. The length direction of the guide groove is parallel to the axial direction of the needle tube.
[0014] By adopting the above technical solution, after the acupuncture is completed, the user fixes the guide sleeve with their left hand and takes the needle tube out of the guide sleeve with their right hand. At this time, the acupuncture needle is kept in the acupuncture state under the stable support of the support hole. At the same time, under the guidance of the guide groove and the guide block, the needle tube can only slide along the axis of the guide sleeve, which effectively avoids unnecessary deviation or shaking of the needle tube in other directions and thus avoids disturbing the acupuncture needle. This reduces the impact of the needle tube removal action on the acupuncture needle state, ensures the accuracy of the acupuncture, and reduces the pain caused by the shaking of the acupuncture needle.
[0015] Optionally, an arc groove communicating with the guide groove is provided on the inner side wall of the guide sleeve.
[0016] By adopting the above technical solution, before needle insertion, the user inserts the needle tube into the guide sleeve through the guide block and guide groove. When the guide block moves to the end of the guide groove, the user rotates the needle tube, and the needle tube drives the guide block to move into the arc groove. At this time, under the restriction of the arc groove, the needle tube and the guide sleeve cannot produce relative vertical movement, so that the needle tube is fixed in the guide sleeve during the needle insertion stage, avoiding the needle tube from sliding up and down in the guide sleeve due to accidental collision or other factors, which would affect the accuracy of the initial position of needle insertion.
[0017] Optionally, the guide sleeve includes two oppositely arranged connecting sleeves, one of each of the two guide grooves and the arc groove on each of the two connecting sleeves, and grooves formed on the opposite surfaces of the two connecting sleeves. A connecting shaft is provided between the two connecting sleeves, and a connecting plate corresponding to each of the two connecting sleeves is hinged to the connecting shaft. The connecting plate is fixedly connected to the corresponding connecting sleeve. A torsion spring is sleeved on the outer surface of the connecting shaft, and the opposite ends of the torsion spring are respectively set on the two connecting plates. In the natural state, the two connecting sleeves surround to form the guide sleeve, and the two grooves surround to form the support hole.
[0018] By adopting the above technical solution, after the needle tube is removed from the guide sleeve, the acupuncture needle is supported by the support hole. At this time, the user presses the two connecting plates in opposite directions, and the two connecting plates rotate around the connecting shaft. At this time, the torsion spring is in a compressed state, and the two connecting sleeves rotate in opposite directions. The rotation of the connecting sleeves opens the support hole. Then the user moves the guide sleeve horizontally until it is completely removed from the acupuncture needle. This setting changes the traditional way of removing the guide sleeve, allowing the acupuncture needle to slide out from inside the guide sleeve. It avoids disturbing the acupuncture needle when the guide sleeve is pulled up along the acupuncture needle, thereby further improving the accuracy of acupuncture needle insertion and reducing the pain caused by the shaking of the acupuncture needle.
[0019] Optionally, the ends of the two connecting sleeves away from the connecting shaft are respectively provided with magnetic blocks of opposite magnetic properties.
[0020] By adopting the above technical solution, after the guide sleeve is removed, the user cancels the force on the connecting plate. When the torsion spring returns to its original position and pushes the two connecting sleeves to stick together and finally form the guide sleeve, the two magnetic blocks attract and stick together, thereby further improving the stability of the connection between the two connecting sleeves and avoiding the possibility of the guide sleeve being accidentally separated due to external interference during use, thus ensuring the smooth removal of the needle tube.
[0021] Optionally, the guide sleeve is made of a transparent material.
[0022] By adopting the above technical solution, during the needle removal process, the user can observe the removal of the needle through the transparent material, and at the same time observe the state of the acupuncture needle in the support hole, which helps the user control the needle insertion process.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. This application achieves automatic adjustment of the needle tube length by setting a threaded sleeve and an adjusting tube. When the needle insertion depth is changed, the user does not need to change different needle tubes, thus improving the applicability of the needle tube.
[0025] 2. By setting a support block, this application can increase the contact area between the needle tube and the human body, making the needle tube more stable on the skin and reducing the needle insertion deviation caused by the shaking of the needle tube.
[0026] 3. This application, by setting a guide sleeve composed of two connecting sleeves, ensures that the needle tube can only slide along the axis of the guide sleeve under the guidance of the guide groove and guide block. This effectively avoids unnecessary offset or shaking of the needle tube in other directions, which could disturb the acupuncture needle. After the needle tube is removed, the user presses the two connecting plates in opposite directions, causing them to rotate around the connecting shaft. At this time, the torsion spring is compressed, and the two connecting sleeves rotate in opposite directions. The rotation of the connecting sleeves opens the support hole. Then, the user moves the guide sleeve horizontally until it is completely removed from the acupuncture needle. This design changes the traditional way of removing the guide sleeve, allowing the acupuncture needle to slide out from inside the guide sleeve, avoiding disturbance of the acupuncture needle as the guide sleeve is pulled upwards along the needle, thereby further improving the accuracy of acupuncture needle insertion.

Detailed Implementation
[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0036] This application discloses an acupuncture needle insertion tube that is easy to locate.
[0037] Example 1
[0038] Reference Figure 1 and Figure 2 An easily positioned acupuncture needle insertion tube includes a needle insertion tube 1, with a threaded sleeve 2 fixedly connected to the end of the needle insertion tube 1. The threaded sleeve 2 is integrally formed with the needle insertion tube 1, and an adjusting tube 21 is internally threaded to the threaded sleeve 2. The axes of the adjusting tube 21, the threaded sleeve 2, and the needle insertion tube 1 are on the same straight line.
[0039] The implementation principle of an easily positioned acupuncture needle insertion tube according to an embodiment of this application is as follows: When it is necessary to change the needle insertion depth, the user first inserts the acupuncture needle into the needle insertion tube 1, and then rotates the adjusting tube 21. With the threaded engagement of the threaded sleeve 2 and the adjusting tube 21, the adjusting tube 21 will move upward along the threaded sleeve 2 during rotation. When the adjusting tube 21 moves to meet the needle insertion depth requirement, the user presses the acupuncture needle until the finger abuts against the end face of the adjusting tube 21, thereby completing the needle insertion. The setting of the threaded sleeve 2 and the adjusting tube 21 realizes the automatic adjustment of the length of the needle insertion tube 1. When changing the needle insertion depth, the user does not need to replace different needle insertion tubes 1, thus improving the applicability of the needle insertion tube 1.
[0040] Example 2
[0041] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that a support block 3 is fixedly connected to the end of the needle tube 1 away from the threaded sleeve 2. The support block 3 is integrally formed with the needle tube 1. The support block 3 is frustoconical in shape and made of transparent material. A through hole 31 communicating with the needle hole of the needle tube 1 is opened on the support block 3. The through hole 31 is used for the insertion of the acupuncture needle. The diameter of the end of the support block 3 away from the adjustment tube 21 is larger than the diameter of the end near the adjustment tube 21.
[0042] The implementation principle of Example 2 is as follows: Before acupuncture, the user places the larger end face of the support block 3 against the acupuncture site of the recipient. At this time, the support block 3 can increase the area of the needle tube 1 in contact with the human body, making the needle tube 1 more stable on the skin. The user can clearly observe the initial state of the needle contact with the skin and the subtle changes of the needle on the skin surface during acupuncture through the support block 3, so as to make timely adjustments.
[0043] Example 3
[0044] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that a guide sleeve 4 is provided on the outer surface of the needle tube 1. The axis of the guide sleeve 4 is in the same straight line as the axis of the needle tube 1. The guide sleeve 4 is made of transparent material so that the user can observe the acupuncture process through the guide sleeve 4.
[0045] Reference Figure 4 and Figure 5 The guide sleeve 4 includes two opposing connecting sleeves 41, both of which are semi-circular. A connecting shaft 42 is provided between the two connecting sleeves 41. Connecting plates 43, corresponding to the two connecting sleeves 41, are hinged to the connecting shaft 42. The connecting plates 43 are fixedly connected to their corresponding connecting sleeves 41. A torsion spring 44 is sleeved on the outer surface of the connecting shaft 42. The two opposite ends of the torsion spring 44 are fixedly connected to the two connecting plates 43. In its natural state, the two connecting sleeves 41 enclose each other to form the guide sleeve 4. The opposing surfaces of the connecting sleeves 41 are provided with guide grooves 411. The outer surface of the needle tube 1 is fixedly connected with a guide block 101 that slides with the guide grooves 411. The inner sidewall of each connecting sleeve 41 is provided with an arc groove 412. The center of the arc groove 412 is located on the axis of the guide sleeve 4 and is connected to the guide groove 411. The opposing surfaces of the two connecting sleeves 41 are provided with grooves 413. When the two connecting sleeves 41 are spliced to form the guide sleeve 4, the two grooves 413 surround to form a support hole 414 for inserting the acupuncture needle.
[0046] Reference Figure 5 and Figure 6 The ends of the two connecting sleeves 41 away from the connecting shaft 42 are respectively fixedly connected with magnetic blocks 5 of opposite magnetic properties. When the two connecting sleeves 41 are spliced together, the two magnetic blocks 5 attract and stick to each other, which improves the stability of the connection of the two connecting sleeves 41 and avoids the possibility of the guide sleeve 4 being accidentally separated due to external interference during use.
[0047] The implementation principle of Example 3 is as follows: Before acupuncture, the user inserts the needle tube 1 into the guide sleeve 4 through the guide block 101 and the guide groove 411. When the guide block 101 moves to the end of the guide groove 411, the user rotates the needle tube 1. The needle tube 1 drives the guide block 101 to move into the arc groove 412. At this time, under the restriction of the arc groove 412, the needle tube 1 and the guide sleeve 4 cannot produce relative vertical movement. Then the user performs the acupuncture operation.
[0048] After the acupuncture is completed, the user fixes the guide sleeve 4 with the left hand and takes the needle tube 1 out of the guide sleeve 4 with the right hand. At this time, the acupuncture needle is kept in the acupuncture state under the stable support of the support hole 414. At the same time, under the guidance of the guide groove 411 and the guide block 101, the needle tube 1 can only slide along the axis of the guide sleeve 4, which effectively avoids unnecessary deviation or shaking of the needle tube 1 in other directions, thereby reducing the impact of the needle tube 1 removal action on the acupuncture state, ensuring the accuracy of the acupuncture, and reducing the pain caused by the shaking of the acupuncture needle.
[0049] After the needle tube 1 is removed from the guide sleeve 4, the acupuncture needle is supported by the support hole 414. At this time, the user presses the two connecting plates 43 in opposite directions. The two connecting plates 43 rotate around the connecting shaft 42. At this time, the torsion spring 44 is in a compressed state. The rotation of the connecting plates 43 drives the two connecting sleeves 41 to rotate in opposite directions. The rotation of the connecting sleeves 41 opens the support hole 414. Then the user moves the guide sleeve 4 horizontally until it is completely removed from the acupuncture needle. This setting changes the traditional way of removing the guide sleeve 4, allowing the acupuncture needle to slide out from inside the guide sleeve 4. This avoids the situation where the guide sleeve 4 disturbs the acupuncture needle when it is pulled up along the acupuncture needle, thereby further improving the accuracy of acupuncture needle insertion.
[0050] After the guide sleeve 4 is removed, the user releases the force applied to the connecting plate 43. The torsion spring 44 resets and drives the two connecting plates 43 to rotate. The rotation of the connecting plates 43 drives the two connecting sleeves 41 to move closer to each other and fit together. At this time, the two magnetic blocks 5 attract each other and fit together, and the guide sleeve 4 resets.
[0051] Example 4
[0052] Reference Figure 7 The difference between this embodiment and Embodiment 1 is that a positioning rib 6 is fixedly connected to the outer surface of the needle tube 1.
[0053] The implementation principle of Example 4 is as follows: the positioning rib 6 restricts the rotation angle of the needle tube 1, thus ensuring the stability of the needle tube 1 in use.
[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
