[0029] Please see Figures 1-5 As shown, in order to stabilize the wrist-ankle needle on the wrist through the wristband 1 structure, the wrist-ankle needle fixing device provided by this utility model includes: wristband 1, fixing plate 2, guide plate 3, and cover plate 4. The wristband 1 is pivotally connected to both ends of the fixing plate 2 to form a ring that fits the wrist. The fixing plate 2 is provided with a guide window 21 at the corresponding position of the wrist. Several needle holes 5 are respectively arranged at preset positions on the guide plate 3. The guide plate 3 is located at the lower position of the guide window 21. The cover plate 4 is hinged to the fixing plate 2 and movably covers the upper position of the guide window 21, creating a sandwich space 22 between it and the guide plate to store and protect the wrist-ankle needle 6 after needle administration.
[0030] In an optional embodiment, to prevent the handle 62 of the wrist-ankle acupuncture needle 6 from wobbling with the patient's movements and causing pain, such as... Figure 4 As shown, the back of the cover plate 4 can be set in a wave-like shape. When the doctor administers the needle, the needle handle 62 will inevitably tilt upwards. At this time, by closing the cover plate 4, the needle handle 62 can be gently pressed in the interlayer space 22 and pressed against the wave-like surface, so as to limit the displacement of the needle handle 62 as much as possible and prevent it from shaking, so as to achieve the effect of fixing the position of the wrist-ankle needle 6.
[0031] Meanwhile, to prevent the cover plate 4 from opening and closing with the patient's wrist rotation rather than by human will, in an optional embodiment, a latch 23 can be provided on one side of the fixing plate 2 and a buckle 24 can be provided on one side of the cover plate 4. In this way, when the cover plate 4 covers the guide window 21, the buckle 24 can be engaged with the latch 23 of the fixing plate 2 to lock the position, thereby preventing the cover plate 4 from opening and closing arbitrarily.
[0032] Furthermore, such as Figures 2-3As shown, due to the individual differences between patients, wrist sizes vary, and in order to facilitate comfortable wearing, in the preferred example, the wristband 1 comprises: magic tape 11, buckle 12, wherein each magic tape 11 is respectively pivoted at both ends of the fixed plate 2, and the second end is respectively inserted into the belt port on both sides of the buckle 12 after winding, and the length is adjusted through self-adhesive binding, thereby realizing the size adjustment function of the wristband 1.
[0033] Further, as shown in Figure 1 , Figure 2 and Figure 4 , in order to facilitate observation of wrist acupoints during needle insertion, the guide sheet 3 is preferably made of transparent PVC material. And the guide sheet 3 can be set in a thin form to better fit the skin and reduce the sense of separation during needle insertion.
[0034] In addition, since the wrist-ankle needle 6 needs to be inserted into the skin at a certain angle and then pushed flat inward during needle insertion, in order to facilitate needle insertion, as shown in Figures 4-5 , in an optional embodiment, the needle insertion hole 5 on the guide sheet 3 can be set as a tapered hole, wherein the bottom diameter of the needle insertion hole 5 can be set to be larger than the wrist-ankle needle head and smaller than the wrist-ankle needle handle, so as to avoid over-limit needle insertion, and the top diameter of the needle insertion hole 5 is larger than the bottom diameter, so that the inclination angle of the side slope of the needle insertion hole allows the basic flat push requirement during needle insertion.
[0035] Further, in order to facilitate the adaptation of different wrist sizes of patients for needle insertion, as shown in Figures 1-2 , in the preferred embodiment, the needle insertion holes 5 on the guide sheet 3 are arranged in pairs and spaced arrays to densely cover the wrist acupoints for needle insertion.
[0036] In addition, in the corresponding embodiment, the guide sheet 3 can also be pre-made to adapt to different wrist sizes to more accurately arrange the corresponding needle insertion holes 5.
[0037] Further, in order to realize the multiplicity of the wrist-ankle needle fixing device, considering that the guide sheet 3 is in direct contact with the human body and the needle body during needle insertion, in order to ensure medical safety and hygiene, it must be discarded after use, and the remaining parts can be used again after disinfection, therefore, in order to reduce the use cost, in the example, the guide sheet 3 and the fixed plate 2 are preferably designed as a detachable and replaceable structure, as shown in Figures 4-5As shown, in the preferred embodiment, the inner wall of the guide window 21 of the fixing plate 2 is provided with a clamping part 7, which comprises a guide wall 71 and a clamping groove 72, wherein the guide wall 71 is arranged on the upper and lower sides of the clamping groove 72 in an inclined manner. Since the guide piece 3 is made of PVC material and has a thin sheet shape, it has a certain flexibility and can be appropriately bent. Therefore, the edge of the guide piece 3 can be introduced into the clamping groove 72 through the guide wall 71 to be connected with the clamping part 7. When disassembled and replaced, the guide piece 3 can be bent and taken out of the clamping groove 72 by pressing, so that a new guide piece 3 can be introduced, thereby completing the replacement and realizing the reusability of the wrist-ankle needle fixing device.
[0038] In addition, it is worth mentioning that due to the replaceability of the first guide piece 3, the guide pieces 3 of different wrist sizes pre-customized in the above example can be replaced and matched according to the situation, so as to better adapt to different patient needs.
[0039] The following examples illustrate the use process of the wrist-ankle needle fixing device. When used for the first time, according to the wrist thickness and needle insertion site requirements of the patient, the guide piece 3 corresponding to the array arrangement of the needle insertion hole 5 is matched and assembled, the size of the wrist strap 1 is adjusted, and then the part of the wrist strap 1 in contact with the skin and the guide piece 3 are disinfected and wiped. After that, the patient wears it. When the needle is inserted, the needle insertion physician inserts the needle according to the wrist acupoint corresponding to the needle insertion hole 5 until the needle is in place. After the needle insertion is completed, the cover plate 4 is closed. After the treatment is completed, the wrist-ankle needle 6 and the guide piece 3 can be discarded together, and the wrist strap 1 and the fixing plate 2 and the cover plate 4 can be disinfected and reused.
[0040] In summary, the wrist-ankle needle fixing device provided by the present application is suitable for wearing on the wrist of the human body, can assist in guiding the insertion of the wrist-ankle needle, can fix the position of the needle body after the needle is inserted, can prevent the displacement of the needle body due to the movement of the patient or the embedding of the needle body into the skin, can avoid the problems of difficulty in taking out the needle body, can also exit the needle insertion hole smoothly when taking out the needle, can avoid stirring, can reduce the pain of the patient, and can prevent the needle body from being missed after the needle body is completely taken out, thereby facilitating clinical use. On the other hand, by wearing the device, the contact between the needle insertion person and the patient's skin can be reduced when the needle is inserted, so as to ensure the sterility and hygiene and reduce the risk of disease transmission.
