Abstract
Description
Technical Field
[0001] This utility model relates to the field of acupuncture needle technology, and in particular to a fully sealed sterile cannula acupuncture needle. Background Technology
[0002] An acupuncture needle is a support device used for acupuncture treatment. An acupuncture needle generally consists of a needle body, a needle tip, and a needle handle. The front end of the needle body is the needle tip, and the rear end is the needle handle. The needle body and needle tip are smooth, while the needle handle is threaded. This is so that it can be lifted, inserted, and rotated during use. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of acupuncture needles.
[0003] Existing acupuncture needles have certain drawbacks in use. Traditional acupuncture needles are sometimes packaged individually, which seems to meet the requirements of aseptic technique. However, when the packaging is opened, the operator's hands often contaminate the needle body and handle to varying degrees. The storage method of multiple needles in the same package makes it easier to contaminate the acupuncture needles and does not meet the requirements of aseptic operation. It is like placing unisolated patients in the same ward - the bacteria-containing air that enters every time the packaging is opened, the cross-contamination caused by finger touch, and the deterioration of the instrument caused by temperature and humidity fluctuations all accumulate the risk of infection. To this end, we propose a fully sealed sterile cannula acupuncture needle. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a fully sealed sterile cannula acupuncture needle. It utilizes a medical composite plastic film to create a fully sealed barrier, allowing for immediate use after tearing at the marked location. The outer membrane of the cannula automatically forms a sterile channel when torn, isolating the fingers from contact with the needle body. This ensures that the needle body, including the handle, remains suspended within the sterile air chamber, with zero air exposure throughout the entire operation. The use of in-membrane sterile field technology reduces the risk of secondary contamination to meet sterile operation requirements, effectively solving the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fully sealed sterile cannula acupuncture needle, comprising a needle body and a composite plastic film, wherein the needle body is sealed and packaged inside the composite plastic film, a first sealing film is provided at the top of the composite plastic film, a second sealing film is provided at the bottom of the composite plastic film, a tear groove is provided on the lower side of the composite plastic film, a needle body is positioned at the lower end of the needle body, a needle tail is integrally formed at the tail of the needle body, a needle heel is integrally formed between the needle body and the needle body, and a needle tip is integrally formed at the end of the needle body.
[0006] Preferably, the needle body is one of a ring handle, a flower handle, a flat handle, and a tube handle.
[0007] Preferably, the two ends of the composite plastic film are aseptically sealed by a first sealing film and a second sealing film, respectively, and the lower end of the composite plastic film is torn open by a tear groove.
[0008] Preferably, the needle body, needle tail, needle heel, needle shaft, and needle tip are integrally formed by compression molding.
[0009] Preferably, the composite plastic film automatically forms a sterile channel when it is torn at the tear groove.
[0010] Preferably, when the composite plastic film is torn open, the needle heel (excluding the needle tip) and the needle body remain suspended within the sterile air chamber.
[0011] Compared with existing technologies, this utility model provides a fully sealed sterile cannula acupuncture needle with the following advantages: This fully sealed sterile cannula acupuncture needle uses a medical composite plastic film to create a fully sealed barrier. It can be used immediately after tearing at the marked point. When the outer film of the cannula is torn, a sterile channel is automatically formed, isolating the fingers from contact with the needle body. This ensures that the needle body, including the needle handle, except for the needle tip, is always suspended in the sterile air chamber. There is zero air exposure throughout the operation. The risk of secondary contamination is reduced to meet the requirements of sterile operation through the sterile field technology inside the membrane. The entire acupuncture needle has a simple structure, is easy to operate, and has better effects than traditional methods. Attached Figure Description

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1-8 As shown, a fully sealed sterile cannula acupuncture needle includes a needle body 1 and a composite plastic film 2. The needle body 1 is sealed inside the composite plastic film 2. A first sealing film 3 is provided at the top of the composite plastic film 2, and a second sealing film 6 is provided at the bottom of the composite plastic film 2. A tear groove 5 is provided on the lower side of the composite plastic film 2. A needle body 4 is positioned at the lower end of the needle body 1. A needle tail 7 is integrally formed at the tail of the needle body 1. A needle heel 8 is integrally formed between the needle body 1 and the needle body 4. A needle tip 10 is integrally formed at the end of the needle body 4. A fully sealed barrier is created using a medical composite plastic film. It can be used immediately after tearing at the marked location. When the outer film of the cannula is torn, a sterile channel is automatically formed, isolating the fingers from contact with the needle body. This ensures that the needle body, including the needle handle, except for the needle tip, is always suspended in the sterile air chamber. There is zero air exposure throughout the operation. The risk of secondary contamination is reduced to meet the requirements of sterile operation through the in-membrane sterile field technology.
[0023] Furthermore, the needle body 1 is one of the following: ring handle 11, flower handle 12, flat handle 13, and tube handle 9.
[0024] Furthermore, both ends of the composite plastic film 2 are aseptically sealed by the first sealing film 3 and the second sealing film 6 respectively, and the lower end of the composite plastic film 2 is torn open by the tear groove 5.
[0025] Furthermore, the needle body 1, needle tail 7, needle heel 8, needle body 4, and needle tip 10 are integrally formed by compression molding.
[0026] Furthermore, when the composite plastic film 2 is torn at the tear groove 5, it automatically forms a sterile channel.
[0027] Furthermore, when the composite plastic film 2 is torn open, the needle base 8, excluding the needle tip 10, including the needle body 1, remains suspended within the sterile air chamber.
[0028] Working Principle: This invention comprises a needle body 1, a composite plastic film 2, a first sealing film 3, a needle body 4, a tear groove 5, a second sealing film 6, a needle tail 7, a needle heel 8, a handle 9, a needle tip 10, a ring handle 11, a floral handle 12, and a flat handle 13. A fully sealed barrier is created using a medical composite plastic film. It is ready to use after tearing at the marked location. When the outer membrane of the cannula is torn, a sterile channel is automatically formed, isolating the fingers from contact with the needle body. This ensures that the needle body, including the handle, except for the needle tip, remains suspended within the sterile air chamber, resulting in zero air exposure throughout the operation. The risk of secondary contamination is reduced to meet aseptic operation requirements through the membrane-based sterile field technology. This invention aims to meet aseptic operation requirements without affecting the operator's needle insertion feel or the implementation of various tonifying and sedating acupuncture techniques, and it also does not affect the implementation of warm needling therapy. The above describes the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
