Description

Technical Field

[0001] The utility model relates to the technical field of acupuncture cannulae, in particular to a disposable adjustable acupuncture needle cannulae. Background Art

[0002] With the strong support of the state for the development of traditional Chinese medicine, the types of diseases treated and the efficacy of acupuncture have been rapidly expanded and improved, and it has also been welcomed by the majority of patients. Many diseases in clinical practice require acupuncture treatment, but most patients are afraid of pain and needles. The use of disposable acupuncture cannulas makes it easy for people who are afraid of needles to accept acupuncture treatment, improves patient compliance, expands the acupuncture population, and improves the efficacy of acupuncture. The cannula needle is a type of acupuncture needle, which is a type of acupuncture needle with fast insertion speed and less pain. It is usually suitable for patients who are afraid of needles and are sensitive to pain. Its application range is no different from that of acupuncture needles, but there are differences in shape and needling method. The cannula needle is composed of a straight-handled acupuncture needle and a plastic cannula. Place the cannula needle (the tip of the acupuncture needle does not exceed the lower end of the cannula) on the acupuncture point to be pierced, hold the cannula with the thumb and middle finger of the left hand, and gently tap the needle handle head on the upper end of the cannula with the right index finger to make the needle tip quickly penetrate the acupuncture point, thereby reducing the pain caused by the needle piercing the skin. At the same time, the cannula also has a pressing effect on the acupuncture point, which can stimulate the qi of the meridians and is more advantageous in regulating qi.

[0003] In clinical acupuncture, different thicknesses and lengths of acupuncture needles are required for different populations, diseases, and acupuncture sites, which means that different lengths of cannulas are required to match. Existing disposable cannula needles are individually packaged, and each acupuncture needle is covered with a transparent plastic cannula. Patients generally use more than 15-20 acupuncture needles of different lengths for each acupuncture treatment. Doctors need to frequently replace and disassemble different cannula needles for acupuncture of the same patient, which is time-consuming and labor-intensive, not conducive to operation, and causes waste of resources and plastic pollution. In the Chinese Patent Literature Library, the patent with the authorization announcement number CN220309418U discloses a stretchable acupuncture funnel cannula, which is convenient for adjusting the length of the cannula as needed by setting relatively adjustable inner and outer tubes, but the two tubes are fixed by the inner tube ring and the outer tube ring, and the firmness is poor. When the needle handle is tapped, the cannula is easily contracted, causing pain and discomfort to the patient; and the cannula is not disposable, and there is a risk of cross infection, affecting medical safety.

[0026] Example 1, an example provided by the present invention, please refer to Figure 1-3: A disposable adjustable acupuncture needle cannula comprises an outer tube 1 and an inner tube 2 movably inserted into the outer tube 1. Both the outer tube 1 and the inner tube 2 are hollow tubular structures with two ends penetrated. The outer diameter of the inner tube 2 is equal to the inner diameter of the outer tube 1. One end of the inner tube 2 extends to the outside of the outer tube 1. A fixing structure 3 is arranged between the outer tube 1 and the inner tube 2. The fixing structure 3 comprises vertical sections 302 symmetrically arranged vertically on both sides of the top of the inner tube 2 and positioning parts 303 respectively arranged on the outer side walls of the two vertical sections 302. The vertical sections 302 are integrally formed with the inner tube 2 and can undergo a certain elastic deformation. The upper edge of the side wall of the outer tube 1 A plurality of groups of fixing holes 301 corresponding to the two positioning parts 303 are provided in the length direction thereof. The positioning parts 303 are inserted into the fixing holes 301 to achieve relative fixation of the outer tube 1 and the inner tube 2. When the length needs to be adjusted, the two positioning parts 303 are pinched toward the middle to slightly bend the two vertical sections 302. The positioning parts 303 are separated from the fixing holes 301 to pull the inner tube 2 to adjust the length of the sleeve. In order to improve the position accuracy of the fixing holes 301 and the positioning parts 303, corresponding limiting slide rails and slide grooves (not shown in the figure) can be provided in the length direction of the inner tube 2 and the outer tube 1.

[0027] The two positioning parts 303 are both provided with a dome at one end away from the vertical section 302, so as to facilitate the inner tube 2 to slide inside the outer tube 1;

[0028] In this embodiment, the number of fixing holes 301 is set to three groups, and the acupuncture needles have three specifications, with needle body lengths of 25mm, 40mm, and 50mm respectively. The sleeve length specifications used are 45mm, 70mm, and 80mm respectively. When the two positioning parts 303 at one end of the inner tube 2 are respectively inserted into the three groups of fixing holes 301, the total sleeve lengths are 45mm, 70mm, and 80mm respectively. The length mark can be set on the outer tube 1 as needed. Clinically, a patient generally needs more than 15-20 acupuncture needles of different lengths for acupuncture treatment. When acupuncturing the same patient, the doctor can quickly adjust the length of the sleeve according to the length of the acupuncture needle, simplifying the doctor's operation. At the same time, acupuncture used to require 15-20 sleeves. Through the adjustable length structure, the same patient only needs to use one sleeve, saving costs, reducing pollution, and avoiding cross infection between different patients.

[0029] A limiting portion 201 is provided at one end of the inner tube 2 extending to the outside of the outer tube 1. Specifically, the limiting portion 201 is a circular ring structure provided on the outer wall of the inner tube 2. On the one hand, it can play a limiting role to prevent the inner tube 2 from being completely retracted into the outer tube 1, making it convenient to pull out the inner tube 2. On the other hand, it can increase the contact area with the patient's skin to reduce discomfort.

[0030] One end of the outer tube 1 is provided with an oblique section 101 for convenient needle insertion, which increases the opening size of the outer tube 1 and facilitates the insertion of acupuncture needles. The structure is simple and practical, and is convenient for production and manufacturing. At the same time, when the sleeve is packaged, the space occupied by the sleeve is reduced.

[0031] Working principle: When the length needs to be adjusted, the two positioning parts 303 are squeezed toward the middle, and the positioning parts 303 are retracted into the inner part of the outer tube 1. Then the inner tube 2 is pulled outward so that the two positioning parts 303 are inserted into different fixing holes 301, thereby realizing the length adjustment and limited fixation of the sleeve. When acupuncture is performed on the same patient, there is no need to frequently replace the sleeve, which can simplify the doctor's operation, save costs, and reduce pollution. At the same time, it is relatively firm and is not easy to cause the sleeve to shrink when tapping the needle handle.

[0032] Example 2, please refer to Figure 4 In this embodiment, based on the embodiment 1, a clamping portion 4 is provided on the outer wall of the outer tube 1. In this embodiment, the clamping portion 4 is fixedly connected to the outer tube 1, and is specifically a vertical rod-shaped structure with one end fixedly connected to the outer tube 1. A gap is provided between the clamping portion 4 and the outer tube 1, so that the sleeve can be clamped on the doctor's clothes, which is convenient for carrying when acupuncture is performed on the same patient.

[0033] Example 3, please refer to Figure 6 The difference between this embodiment and embodiment 2 is that a clamping portion 401 is fixed to one end of the clamping portion 4, the clamping portion 401 and the clamping portion 4 are integrally formed, and the clamping portion 401 is a C-shaped structure with an opening on one side and has a certain elastic deformation. The clamping portion 401 is used to be clamped and fixed on the outer side of the outer tube 1, and the clamping portion 4 is a U-shaped structure with an opening facing downward, and its open end is located at the end of the clamping portion 4 away from the clamping portion 401. The clamping portion 4 and the sleeve are detachably connected by providing the clamping portion 401. The material of the clamping portion 4 can be metal or a plastic material with a certain elastic deformation, which is not limited here. When in use, the clothes are inserted into the opening in the middle of the clamping portion 4 to clamp and fix the clamping portion 4, and then the sleeve is inserted into the inside of the clamping portion 401 from the opening of the clamping portion 401. It is convenient to take, and the clamping portion 4 can be recycled to further reduce resource waste.
