Description

Technical Field

[0001] The present application relates to the technical field of acupuncture instruments, and in particular to an acupuncture depth marking device. Background Art

[0002] Acupuncture is the general term for acupuncture and moxibustion. Acupuncture refers to inserting needles (usually filiform needles) into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, using acupuncture techniques such as twisting and lifting to stimulate specific parts of the human body to achieve the purpose of treating diseases.

[0003] In this regard, China's patent application number CN202020788065.8 discloses an acupuncture depth marking device. This scheme mainly involves inserting the acupuncture needle into the acupuncture point. The bottom arc plate is located around the acupuncture point and moves upward relative to the acupuncture needle. The side guide rod moves relatively along the measuring ruler to indicate the depth of the acupuncture needle without leaving the needle, thereby avoiding adverse consequences caused by excessive insertion of the acupuncture needle.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] Although the above scheme can see the insertion depth, the actual insertion depth and insertion speed still depend on the feel, which affects the accuracy of acupuncture. Utility Model Content

[0006] In order to make up for the above shortcomings, the present application provides an acupuncture depth marking device, which aims to improve the problems mentioned in the above background technology.

[0007] An embodiment of the present application provides an acupuncture depth marking device, comprising a shell, a needle tube being fixedly connected to the shell, a piston and a fine needle being arranged in the needle tube, the piston being detachably connected to the fine needle, an exhaust hole being provided at the lower end of the needle tube, an ejection piece being connected to the piston, a positioning ring being screwed on the shell, and the positioning ring being movably connected to the ejection piece.

[0008] In a specific embodiment, the ejection member includes a push block and a push rod, the push rod is fixedly connected to the push block, the push block is movably connected to the housing, and the lower end of the push rod is fixedly connected to the piston.

[0009] In a specific implementation manner, the ejection member further includes a spring, the spring movably presses against the push block, an inverted L-shaped slide groove is formed through the side wall of the shell, and the push block moves along the slide groove.

[0010] In the above implementation process, the push block is pulled backward and rotated to be stuck in the upper end of the slide slot. When started, the push block is pushed back, and the spring pushes the push block and the push rod to push the piston downward, thereby pushing the acupuncture needle into the human body.

[0011] In a specific implementation manner, the push block passes through the slide groove, and the positioning ring movably presses against the push block.

[0012] In the above implementation process, the push block extends out of the slide slot to facilitate hand pinching, and the positioning ring is used to provide positioning for the moving distance of the push block, thereby achieving positioning of the acupuncture depth.

[0013] In a specific embodiment, the piston is magnetically connected to the needle.

[0014] In the above implementation process, the acupuncture needle is connected to the piston by magnetic attraction, which is convenient for disassembly and replacement. In this embodiment, the magnetic attraction force is very weak as long as the acupuncture needle can be sucked and not fall off. After the acupuncture needle is inserted into the skin, the outer shell can be directly removed by utilizing the binding force of the skin on the acupuncture needle.

[0015] In a specific embodiment, the exhaust hole runs through the housing.

[0016] In a specific embodiment, two exhaust holes are provided.

[0017] In the above implementation process, one of the exhaust holes can be blocked manually, or both can be blocked, or neither can be blocked, so as to adjust the speed at which the acupuncture needle enters the human body.

[0018] In a specific embodiment, a scale is provided on the side wall of the shell.

[0019] In the above implementation process, the position of the positioning circle can be intuitively read through the scale, and the depth to which the needle will be inserted.

[0020] Compared with the prior art, the beneficial effects of the present application are: the positioning ring is used to control the ejection distance of the ejection member, thereby controlling the depth of the fine needle inserted into the skin; in addition, when the fine needle is pushed by the piston, the internal pressure of the needle tube increases, and the airflow overflows from the exhaust hole in a restricted manner, thereby controlling the speed of the fine needle inserted into the skin, which is beneficial to ensure the consistency of the acupuncture technique.

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1-Figure 4 The present application provides an acupuncture depth marking device, including a housing 10, a needle tube 20 is fixedly connected in the housing 10, a piston 30 and a fine needle 40 are arranged in the needle tube 20, the piston 30 and the fine needle 40 are detachably connected, an exhaust hole 50 is opened at the lower end of the needle tube 20, an ejection member 60 is connected to the piston 30, a positioning ring 70 is screwed on the housing 10, and the positioning ring 70 is movably connected to the ejection member 60. Among them, the positioning ring 70 is used to control the ejection distance of the ejection member 60 to control the depth of the fine needle 40 inserted into the skin. In addition, when the fine needle 40 is pushed by the piston 30, the internal pressure of the needle tube 20 increases, and the airflow overflows from the exhaust hole 50 in a restricted manner, thereby controlling the speed of the fine needle 40 inserting into the skin, which is conducive to ensuring the consistency of the acupuncture technique.

[0029] See also Figure 1-Figure 4 The ejection member 60 includes a push block 61 and a push rod 62. The push rod 62 is fixedly connected to the push block 61. The push block 61 is movably connected to the housing 10. The lower end of the push rod 62 is fixedly connected to the piston 30. The ejection member 60 also includes a spring 63. The spring 63 is movably pressed against the push block 61. An inverted L-shaped slide groove is provided through the side wall of the housing 10. The push block 61 moves along the slide groove. The push block 61 is pulled backward and rotated to be stuck at the upper end of the slide groove. When the push block 61 is started, the push block 61 is pushed back. The spring 63 pushes the push block 61 and the push rod 62 to push the piston 30 downward, thereby pushing the acupuncture needle 40 into the human body.

[0030] See also Figure 1-Figure 4The push block 61 passes through the slide groove, and the positioning ring 70 is movably pressed against the push block 61. The push block 61 extends out of the slide groove for easy hand pinching, and the positioning ring 70 is used to provide positioning for the moving distance of the push block 61, thereby realizing the positioning of the acupuncture depth.

[0031] See also Figure 1-Figure 4 The piston 30 is magnetically connected to the needle 40. The needle 40 is connected to the piston 30 by magnetic attraction, which is convenient for disassembly and replacement. In this embodiment, the magnetic attraction force is very weak, as long as the needle 40 can be attracted and not fall off. After the needle 40 is inserted into the skin, the housing 10 can be directly removed by using the binding force of the skin on the needle 40.

[0032] See also Figure 1-Figure 4 The exhaust hole 50 runs through the housing 10. Two exhaust holes 50 are provided. One of the exhaust holes 50 can be blocked manually as needed, or both of them can be blocked, or neither of them can be blocked, so as to adjust the speed at which the fine needle 40 enters the human body.

[0033] See also Figure 1-Figure 4 A scale 80 is provided on the side wall of the housing 10. The position of the positioning ring 70 can be intuitively read through the scale 80, and the depth to which the fine needle 40 will be inserted.

[0034] The working principle of the acupuncture depth marking device is: pull the push block 61 backward and rotate it to get stuck in the upper end of the slide slot, rotate the positioning ring 70 to the position of the specified scale 80, and determine the acupuncture depth. When started, push the push block 61 backward, and the spring 63 pushes the push block 61 and the push rod 62 to push the piston 30 downward, thereby pushing the needle 40 into the human body. During the movement of the piston 30, the air in the needle tube 20 is pushed out through the exhaust hole 50. The exhaust hole 50 can limit the air exhaust speed, thereby limiting the speed at which the needle 40 is inserted into the skin. The push block 61 stops after contacting the positioning ring 70, and the insertion depth is determined. Then, the binding force of the skin on the fine needle 40 can be used to directly remove the outer shell 10, and the fine needle 40 can remain on the skin. In summary, the positioning ring 70 is used to control the ejection distance of the ejection member 60, thereby controlling the insertion depth of the fine needle 40 into the skin. In addition, when the fine needle 40 is pushed by the piston 30, the internal pressure of the needle tube 20 increases, and the airflow overflows from the exhaust hole 50 in a restricted manner, thereby controlling the speed at which the fine needle 40 is inserted into the skin, which is beneficial to ensure the consistency of the acupuncture technique.
