Description

Technical Field

[0001] The invention relates to the technical field of sterile intradermal needles for physical therapy, and more particularly to a sterile intradermal needle that is convenient to use. Background Art

[0002] Sterile intradermal needles are micro-acupuncture needles. When used, the needle tip is pressed and buried in the corresponding acupuncture point under the skin. The needle burial time is generally 1 to 2 days, and it can be up to 6 to 7 days depending on the condition. Sterile intradermal needle treatment is the result of the combination of traditional medicine and modern electrochemical principles. Since the sterile intradermal needle tip is extremely fine, the treatment is particularly safe.

[0003] At present, when sterile intradermal needles are used, adhesive tape is pre-pasted on the outer end of the needle handle. When the sterile intradermal needle is buried subcutaneously or in an acupuncture point, the adhesive tape is immediately attached to the skin surface, which is very convenient. However, since the sterile intradermal needle needs to stay on the skin for a certain period of time, when the sterile intradermal needle is used in the arm or leg, the activity of such parts is large, and the adhesive tape surface may be detached during this process, which may cause the sterile intradermal needle to fall off. This not only affects the physical therapy effect of the sterile intradermal needle, but also the dropped sterile intradermal needle may cause certain safety problems.

[0004] Therefore, in view of this, the existing structure is studied and improved to provide a convenient-to-use sterile intradermal needle, in order to achieve a more practical purpose. Summary of the invention

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] ① In this scheme, when applying a sterile intradermal needle to a position such as an arm or leg with a large amount of activity, an adhesive film is used to provide a fulcrum for the operation. After completing the disinfection of the arm or leg, the sterile intradermal needle is inserted into the subcutaneous tissue at the corresponding position of the arm or leg. Then, the stickiness of the round breathable adhesive tape is used to make it adhere closely to the skin. Then, the arm or hand is wrapped and fixed with an auxiliary fixing component, which further greatly improves the fitting effect of the sterile intradermal needle and the skin. At the same time, the auxiliary fixing component can effectively increase the display area of ​​the sterile intradermal needle and reduce the risk of accidental collision or pressing of the sterile intradermal needle by others.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1 - Figure 7 A convenient-to-use sterile intradermal needle includes an epoxy resin needle cap 1. The epoxy resin needle cap 1 is formed by curing epoxy resin. The epoxy resin is used instead of the common acrylic resin. When the epoxy resin needle cap 1 contacts the skin, the harmful stimulation to the skin can be effectively reduced or avoided.

[0048] A needle handle 2 is fixed on an epoxy resin needle cap 1, a hollow needle rod 3 is fixedly connected to the needle handle 2, and a needle tip 4 is fixed on the hollow needle rod 3. The needle handle 2, the hollow needle rod 3, and the needle tip 4 are an integrated structure. When the entire sterile intradermal needle is in use, the needle tip 4 and most of the hollow needle rod 3 will penetrate subcutaneously and irritate the skin. Then, the needle handle 2 and a small part of the hollow needle rod 3 remain outside the skin. In this way, the penetration depth of the sterile intradermal needle can be effectively controlled, and at the same time, the needle removal operation at the end of the use of the sterile intradermal needle is convenient.

[0049] The circular breathable adhesive tape 5 fixed on the other side of the epoxy resin needle cap 1 contacts the skin surface when the needle tip 4 and the hollow needle shaft 3 of the sterile intradermal needle are inserted into the subcutaneous tissue. At the same time, the circular breathable adhesive tape 5 is adhered to the skin surface by utilizing its own viscosity.

[0050] A sticky film 6 is fixedly provided at the center position of the side of the circular breathable adhesive tape 5 away from the epoxy resin needle cap 1. A box of medical sterile intradermal needles may include six or eight sterile intradermal needles. The sticky film 6 can be used to fix a single sterile intradermal needle on the sticker plate inside the box. At the same time, the sticky film 6 is also easy to separate from the sticker plate, which is convenient for taking a single sterile intradermal needle.

[0051] Auxiliary fixing components 7 are arranged at both ends of the side of the circular breathable adhesive tape 5, and the two auxiliary fixing components 7 are respectively located on both sides of the adhesive film 6. When the sterile intradermal needle is inserted into the subcutaneous tissue and forms stimulation, the circular breathable adhesive tape 5 is attached to the skin surface. At this time, the auxiliary fixing component 7 can be used to form a secondary fixation of the entire sterile intradermal needle. When the sterile intradermal needle stays under the skin, the double fixation of the circular breathable adhesive tape 5 and the auxiliary fixing component 7 can effectively prevent the sterile intradermal needle from falling off the skin.

[0052] The interior of the hollow needle rod 3 is filled with a physiotherapy liquid bag 301, and the physiotherapy liquid in the physiotherapy liquid bag 301 can play an auxiliary effect on the physiotherapy of the sterile intradermal needle.

[0053] A transparent rubber protective cap 501 is provided on the side of the circular breathable adhesive tape 5 close to the epoxy resin needle cap 1. The transparent rubber protective cap 501 can protect the needle handle 2, the hollow needle rod 3, and the needle tip 4. At the same time, it can be observed whether the needle handle 2, the hollow needle rod 3, and the needle tip 4 are bent.

[0054] The auxiliary fixing component 7 includes a cloth storage groove 701 fixed on the circular breathable adhesive tape 5, and the cloth storage groove 701 can provide a storage space.

[0055] A partition bar 702 is fixedly provided at the inner center of the cloth storage slot 701 , and the partition bar 702 can partition the inner space of the cloth storage slot 701 , thereby ensuring that the materials on both sides of the partition bar 702 do not interfere with each other.

[0056] Patches 703 are fixedly provided at both ends of the dividing bar 702, and a transparent film strip 704 is fixedly provided on the side of the patch 703 away from the dividing bar 702. A traction head 705 is fixedly provided at one end of the transparent film strip 704. The patch 703 limits one end of the transparent film strip 704. When the traction head 705 is pulled, the patch 703 can limit the length of the transparent film strip 704 being pulled out. After the transparent film strip 704 is pulled out with the traction head 705, it can wrap the circular breathable adhesive tape 5 and the hands or legs of the physiotherapy.

[0057] A medical adhesive 706 is fixed on one of the traction heads 705, a release paper 707 is attached to the surface of the medical adhesive 706, and a binding tape 708 is fixed on the side of the traction head 705. After one of the traction heads 705 surrounds the hand or leg of the patient, the release paper 707 is removed, and the medical adhesive 706 can be used to bond with the other traction head 705 or the transparent film tape 704, thereby forming a ring-shaped binding on the hand or leg of the patient, thereby improving the effect of the circular breathable adhesive tape 5 and even the entire sterile intradermal needle being tightly attached to the skin.

[0058] Embodiment 2:

[0059] Based on the above embodiment 1, further description is given.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 Specifically, the needle handle 2 is an L-shaped structure made of stainless steel, and the volume of the needle handle 2 embedded in the epoxy resin needle cap 1 accounts for no less than 90%.

[0061] Ensure that the needle handle 2 has sufficient contact with the epoxy resin needle cap 1, thereby ensuring that the epoxy resin needle cap 1 has sufficient binding force on the needle handle 2, and ensuring that the epoxy resin needle cap 1 has sufficient binding force on the hollow needle rod 3 and the needle tip 4. When the epoxy resin needle cap 1 is in close contact with the skin, it is the maximum depth of the sterile intradermal needle inserted into the subcutaneous tissue.

[0062] See also Figure 5 Specifically, the hollow needle rod 3 is a hollow tube structure made of stainless steel, and the physiotherapy liquid bag 301 is filled inside the hollow tube of the hollow needle rod 3. The physiotherapy liquid bag 301 is stored in the hollow tube. When the hollow needle rod 3 is inserted into the subcutaneous tissue, the physiotherapy liquid bag 301 is simultaneously brought into the subcutaneous component, and the liquid in the physiotherapy liquid bag 301 is used to assist the stimulation effect of the sterile intradermal needle and improve the use effect of the sterile intradermal needle.

[0063] Six through holes 302 are formed on the side of the hollow needle rod 3, and two through holes 302 form a group, are at the same height, and are interconnected.

[0064] By using the through hole 302, the inside and outside of the hollow tube can be connected, thereby ensuring that the therapeutic liquid inside the hollow tube can flow out from the through hole 302 and remain in the subcutaneous position. At the same time, the through hole 302 has a small diameter and will not affect the process of the sterile intradermal needle being inserted into the subcutaneous tissue.

[0065] Specifically, the coating surface of the physiotherapy liquid package 301 is a fat-soluble membrane structure, and the liquid inside the physiotherapy liquid package 301 is glucocorticoid.

[0066] When the physiotherapy liquid bag 301 follows the hollow needle rod 3 to the subcutaneous tissue, the coating of the fat-soluble membrane structure will be dissolved, and then the internal glucocorticoid will be released to the subcutaneous tissue. In sterile intradermal needle treatment, glucocorticoid can reduce inflammatory response and improve symptoms, playing an auxiliary role in sterile intradermal needle treatment.

[0067] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 Specifically, the side of the circular breathable adhesive tape 5 close to the epoxy resin needle cap 1 is an adhesive surface, and a release film 502 is attached to the adhesive surface.

[0068] Specifically, the transparent rubber protective cap 501 includes a rubber disc 5011 and a rubber cap 5012. The rubber disc 5011 and the rubber cap 5012 are an integrally formed structure. The rubber disc 5011 is in close contact with the release film 502. The rubber disc 5011 and the rubber cap 5012 can provide sterile protection for the needle handle 2, the hollow needle shaft 3 and the needle tip 4 of the sterile intradermal needle. At the same time, when taking the sterile intradermal needle, the needle tip 4 of the sterile intradermal needle can be prevented from pricking the hand. When the sterile intradermal needle is in use, the transparent rubber protective cap 501 is removed, and the release film 502 can be removed at the same time by utilizing the adhesion between the rubber disc 5011 and the release film 502, thereby facilitating the circular breathable adhesive tape 5 to adhere to the skin.

[0069] The rubber cap 5012 is located outside the hollow needle rod 3 and the needle tip 4. The rubber cap 5012 is a slender structure and does not contact the hollow needle rod 3 and the needle tip 4. At the same time, it can provide good protection for the hollow needle rod 3 and the needle tip 4.

[0070] See also Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 Specifically, hard fixing strips 7011 are fixedly installed at both ends of the cloth storage groove 701, and the binding tapes 708 are attached to the hard fixing strips 7011. The number of binding tapes 708 set on each traction head 705 is four.

[0071] When the sterile intradermal needle has not been used, the positioning tape 708 is attached to the hard fixing strip 7011, which can limit the position of the other end of the transparent film tape 704 and the traction head 705, preventing the traction head 705 from accidentally pulling out the transparent film tape 704. At the same time, it can ensure that the traction head 705 is outside the cloth storage groove 701, which is convenient for the subsequent traction use of the traction head 705.

[0072] When the traction head 705 is pulled out, the binding tape 708 can be folded and attached to the side of the traction head 705 by utilizing the stickiness of the binding tape 708 , so that the use of the traction head 705 will not be affected.

[0073] Specifically, the transparent film strip 704 is stored in the cloth storage slot 701 in a folded shape, and the length of a single transparent film strip 704 is not less than six times the length of the cloth storage slot 701 .

[0074] Ensure that there are sufficient transparent film strips 704 inside the cloth storage groove 701, and when the traction head 705 drives the transparent film strips 704 to be pulled out, ensure that the total length of the two transparent film strips 704 is sufficient to wrap around the hands or legs of the person being treated.

[0075] Specifically, circular diaphragms 601 are fixedly disposed on both sides of the adhesive film 6 , and the two circular diaphragms 601 are symmetrically disposed.

[0076] When taking a sterile intradermal needle, the thumb and middle finger can be used to stick to a circular membrane 601 respectively, and then the index finger is used to block the adhesive film 6, and the two circular membranes 601 are pinched together. This can facilitate the use of the sterile intradermal needle and will not cause contamination to the hollow needle shaft 3 and needle tip 4 of the sterile intradermal needle.

[0077] Embodiment 3:

[0078] Based on the above-mentioned Embodiment 1 and Embodiment 2, further description is given.

[0079] The circular breathable adhesive tape 5, the adhesive film 6 and the cloth structure in the auxiliary fixing component 7 of the sterile intradermal needle can be bent to a certain extent and have a certain elasticity, which can fully adapt to different physical treatment parts.

[0080] When the sterile intradermal needle is applied and the needle is removed, the circular breathable adhesive tape 5 can be folded in half and attached to the outer surface of the hollow needle shaft 3 and the needle tip 4, and then the transparent film tape 704 is wrapped around the outside of the circular breathable adhesive tape 5 in circles, and finally the medical adhesive 706 at the position of the traction head 705 is used to fit the transparent film tape 704, so that the hollow needle shaft 3 and the needle tip 4 of the sterile intradermal needle can be effectively wrapped. When the sterile intradermal needle is discarded or waiting for recycling, the hollow needle shaft 3 and the needle tip 4 can be effectively avoided from causing harm to relevant personnel, thereby ensuring the safety of the sterile intradermal needle when it is discarded or waiting for recycling.

[0081] Working principle:

[0082] When taking out the sterile intradermal needle, use the sticky film 6 to detach a single sterile intradermal needle from the sticker plate inside the box, then use the thumb and middle finger to stick to a circular film 601 respectively, then use the index finger to block the sticky film 6, pinch the two circular film 601 together, and then remove the transparent rubber protective cap 501, and then you can perform sterile intradermal needle therapy on the area where the sterile intradermal needle is applied and disinfected.

[0083] The needle tip 4 and most of the hollow needle shaft 3 will penetrate into the subcutaneous tissue and irritate the skin. Then, the needle handle 2 and a small part of the hollow needle shaft 3 will remain outside the skin. At this time, the round breathable adhesive tape 5 is attached to the skin.

[0084] Then, pull the traction head 705, and the transparent film tape 704 is pulled out along with the traction head 705. When one of the traction heads 705 surrounds the hand or leg of the patient, remove the release paper 707, and use medical adhesive 706 to bond it to the other traction head 705 or the transparent film tape 704, thereby forming a ring-shaped restraint on the hand or leg of the patient, thereby improving the effect of the circular breathable adhesive tape 5 and even the entire sterile intradermal needle when they are in close contact with the skin.

[0085] As the hollow needle shaft 3 of the sterile intradermal needle remains in the subcutaneous tissue, the coating of the fat-soluble membrane structure will be dissolved, thereby releasing the internal glucocorticoid to the subcutaneous tissue. During sterile intradermal needle treatment, glucocorticoid can reduce inflammatory response and improve symptoms, playing an auxiliary role in sterile intradermal needle treatment.

[0086] In this way, the entire use of the sterile intradermal needle can be completed, and the use method is simple and quick. The sterile intradermal needle after use can be effectively attached to the skin. When removing the needle, the transparent film strip 704 and the round breathable adhesive tape 5 can be separated in sequence.

[0087] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
