[0033] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0034] In the following description, embodiments of the invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0035] To address the technical problem that traditional acupuncture needles cannot transfer accumulated gas to the patient's body during intestinal obstruction treatment, this invention provides an acupuncture device for intestinal gas expulsion. While performing acupoint stimulation therapy, it can immediately expel accumulated gas from the intestinal tract, rapidly relieve the patient's abdominal distension symptoms, and promote the relief of intestinal obstruction.

[0036] This invention provides an acupuncture device for intestinal gas relief, as described in the following embodiment. Figure 1 The device includes a needle body 1 and an anti-clogging element. For example, the anti-clogging element may be a needle core, an air bladder, a sheath, or an outer sheath.

[0037] The needle body 1 has a first puncture section 11 at its first end, and at least one first vent hole 12 on the side wall near the first puncture section 11. The needle body 1 has a venting cavity 13 inside, which communicates with the first vent hole 12 and the second end of the needle body 1. The needle body 1 can be punctured into the intestine of the patient's abdomen through the first puncture section 11. Gas in the intestine can enter the venting cavity 13 through the first vent hole 12 and finally be discharged from the second end of the needle body 1. This design allows the needle to exert its acupoint stimulation effect while directly discharging gas from the intestine after insertion, achieving direct clearance of pathological products and quickly relieving abdominal distension symptoms of intestinal obstruction. For patients with malignant intestinal obstruction, compared to surgical and drug treatments, the acupuncture device of this embodiment can better alleviate abdominal distension symptoms and is more effective. Existing acupuncture therapies are mostly water-based acupuncture and acupoint injection therapy, focusing on injecting therapeutic substances into the body. The acupuncture device of this embodiment can be used to discharge gas from the body and can be used for the treatment of intestinal obstruction and intestinal gas accumulation.

[0038] To prevent muscle fibers from easily blocking the gas passage during needle insertion, an anti-blocking element is provided on the inner or outer side of the needle body 1. The anti-blocking element extends along the axis of the needle body 1 and has continuous or spaced anti-blocking walls. The anti-blocking element is separately provided from the needle body 1 and can move relative to the needle body 1, which facilitates the switching between the closed and open states of the first exhaust hole 12. The anti-blocking element prevents the gas passage from being blocked by blocking or covering the first exhaust hole 12 through the anti-blocking walls.

[0039] For example, the anti-blocking element can be moved to a first position or a second position relative to the needle body 1. When the anti-blocking element is in the first position, the anti-blocking wall surface is in contact with the end of the first vent hole 12, which can cover the first vent hole 12 during needle insertion to prevent muscle, connective tissue, etc. from embedding or blocking the channel. When the needle body reaches the target position, the anti-blocking element can be moved to the second position, and the anti-blocking wall surface is offset from the first vent hole 12, which opens the first vent hole 12, ensuring that the accumulated air can smoothly pass through the first vent hole 12 into the venting cavity 13 and be discharged, thus ensuring the reliability of the venting function.

[0040] During the assembly process of the acupuncture device in the above embodiments, the operator can manually place the anti-blocking element in the first position. During the puncture treatment, after the puncture is completed, the medical staff can manually pull the anti-blocking element located in the first position to the second position.

[0041] The acupuncture device described in the above embodiment retains the traditional acupuncture function regulation of the gastrointestinal tract, adds a direct and effective exhaust channel, and solves the problem of easy blockage of the channel. It realizes the active and rapid elimination of gas accumulation in intestinal obstruction, thereby achieving the therapeutic goal of relieving symptoms such as abdominal distension and pain more quickly and effectively, and improving the patient's treatment experience and quality of life.

[0042] To achieve the goals of this invention, the blocking element can be placed on the inner and / or outer side of the needle body. Referring to Embodiments 1 and 2, placing the anti-blocking element on the inner side of the needle body does not affect the external dimensions of the needle body and can reduce pain during puncture. Referring to Embodiments 3 and 4, placing the anti-blocking element on the outer side of the needle body reduces the manufacturing difficulty of the anti-blocking element. Of course, a mixed arrangement of anti-blocking elements also aligns with the goals of this invention; for example, simultaneously placing anti-blocking elements on both the outer and inner sides of the needle body can further enhance the effect of preventing blockage of the first vent hole, effectively doubling the anti-blocking effect.

[0043] Example 1 This embodiment uses a built-in needle core 2 for sealing. The needle core 2 has a simple structure, strong sealing ability, and is easy to install and disassemble. (Refer to...) Figure 1 The acupuncture device also includes a first traction member 31 and an anti-clogging element including a needle core 2. The needle core 2 is made of an elastic material and is located within the exhaust cavity 13. At least a portion of the structure of the needle core 2 corresponds to the position of the first exhaust hole 12. The outer wall of the needle core 2 is used to press against the inner edge of the first exhaust hole 12. The needle core 2 can be a columnar structure or other shapes. Before being inserted into the exhaust cavity 13, its outer diameter is slightly larger than its inner diameter. After entering the exhaust cavity 13, the needle core 2 is in a taut state. The outer wall of the needle core 2 can serve as an anti-clogging wall, preventing blockage of the first exhaust hole 12 by pressing against it. Because the needle core 2 is elastic, its outer wall can adapt to the microscopic shape of the edge of the first exhaust hole 12, achieving uniform pressing even with minor unevenness, thereby improving the reliability of the seal. Simultaneously, because the needle core 2 can be made of an elastic material, it is less prone to jamming during movement, ensuring smooth switching between the first and second positions. In this embodiment, the first position can refer to the position where the core 2 completely covers all the first exhaust holes 12, and the second position can refer to the position where the core 2 is completely moved outside the exhaust cavity 13 or other positions that do not cover all the first exhaust holes 12.

[0044] The first end of the first pulling member 31 is fixedly connected to the end of the needle core 2 away from the first puncture part 11. The second end of the first pulling member 31 passes through the second end of the needle body 1 and is located outside the needle body 1. The first pulling member 31 is configured to move the needle core 2 out of the needle body 1 under the action of external force. The end of the first pulling member 31 has a pull ring 33. When it is necessary to activate the venting function, simply pull the first pulling member 31 under the action of external force to move the needle core 2 from the venting cavity 13 to the outside of the needle body 1, so that the needle core 2 is separated from the area of ​​the first venting hole 12, that is, switch from the first position to the second position. At this time, the first venting hole 12 is fully exposed, and the gas accumulated in the intestine can be smoothly discharged through the venting cavity 13.

[0045] Example 2 This embodiment uses a built-in airbag 21 for sealing. The airbag 21 can better adapt to the inner edge of the first exhaust port 12, resulting in a good sealing effect. (Refer to...) Figure 2 The acupuncture device also includes a second traction member 32, and anti-clogging elements include an airbag 21 and a sealing plug 22. The airbag 21 has an opening facing the second end of the needle body 1; at least a portion of the structure of the airbag 21 corresponds to the position of the first exhaust port 12. When the airbag 21 is filled with a filling medium, the outer wall of the airbag 21 is used to press against the inner edge of the first exhaust port 12. The outer wall of the airbag 21 can serve as an anti-clogging wall surface, and it can expand when filled with the filling medium, thereby tightly pressing against the inner edge of the first exhaust port 12.

[0046] In the above embodiment, a portion of the structure of the sealing plug 22 is adapted to the opening and is detachably connected to the opening. The first end or middle of the second pulling member 32 is fixedly connected to the sealing plug 22, used to drive the sealing plug 22 to separate from the opening. When venting is required, pulling the second pulling member 32 will cause the sealing plug 22 to separate from the opening of the airbag 21. The filling medium (e.g., air) inside the airbag 21 can be discharged through the opening, causing the airbag 21 to contract and its outer wall to separate from the first vent hole 12, thereby opening the venting channel, the first vent hole 12. The first position can refer to the position where the outer wall of the airbag 21 presses against the first vent hole 12 after inflation, and the second position can refer to the position where the outer wall of the airbag 21 moves away from the first vent hole 12 after deflation and contraction.

[0047] In some embodiments, refer to Figure 2 The sealing plug has an inflation channel 221 connecting its two ends. A spring piece 222 is provided at one end of the sealing plug for embedding into the opening. The root of the spring piece 222 is fixedly connected to the sealing plug, and the middle part of the spring piece 222 covers the end of the inflation channel 221. The inflation channel 221 and the spring piece 222 in the sealing plug form a one-way valve. During the inflation of the airbag 21, refer to... Figure 2Gas flows from the left side to the right side of the inflation channel 221. Driven by the airflow, the spring 222 is lifted, allowing gas to fill the airbag 21. After inflation, the pressure inside the airbag 21 is greater than the pressure outside, that is, the pressure on the right side of the spring 222 is greater than the pressure on the left side, thus making the spring 222 press tightly against the end of the inflation channel 221 to prevent air leakage.

[0048] In some embodiments, the airbag 21 is fixedly connected to the second traction member 32, as shown in the reference. Figure 2 The second pulling member 32 is fixedly connected to the sealing plug at its middle part and to the air bladder 21 at its end. The connection between the second pulling member 32 and the air bladder 21 has a loose pull cord. The length of this pull cord when taut is greater than the length of the sealing plug embedded in the air bladder 21. When the second pulling member 32 is pulled, it first causes the sealing plug to detach from the air bladder 21, causing the air bladder 21 to contract. Then, the loose pull cord gradually tightens, causing the air bladder 21 and the sealing plug to move out of the needle body. The second pulling member 32 includes a pull cord, and its second end has a pull ring 33, which facilitates gripping and applying force by the operator. The portion of the second pulling member 32 located outside the air bladder can also be a pull rod.

[0049] Example 3 This embodiment uses an external sheath 91 for sealing, employing a method of first puncturing and then opening the vent hole, which is simple and quick to operate. (Refer to...) Figure 3 The acupuncture device also includes a limiting member 92 and an anti-clogging element including a sheath 91. The first end of the sheath 91 has a second puncture portion 911, and the side wall of the sheath 91 has a second vent hole 912. The projection of the second vent hole 912 radially onto the sheath 91 corresponds to the position of the first vent hole 12 located on the same side. The sheath 91 is sleeved on the outside of the needle body 1 and is slidably connected to the needle body 1. A predetermined distance is reserved between the first end of the sheath 91 and the first end of the needle body 1. The inner wall of the sheath 91 serves as an anti-clogging wall surface, preventing the first vent hole 12 from becoming blocked when it covers it. The diameter of the second vent hole 912 can be set to be equal to or greater than the diameter of the first vent hole 12.

[0050] In the above embodiment, the limiting member 92 is detachably disposed on the outer wall of the needle body 1, and the limiting member 92 abuts against the second end of the sheath tube 91, as shown in the figure. Figure 4The limiting member 92 has a C-shaped cross-section and can be made of an elastic material. It can be fixed to the needle body 1 by its own deformation and can be removed from the needle body 1 by the user pulling it. When the limiting member 92 is installed and the needle body 1 is inserted into the sheath 91, the second vent hole 912 and the first vent hole 12 are offset in the axial direction of the needle body 1. When the limiting member 92 is removed and the needle body 1 is fully inserted into the sheath 91, the first vent hole 12 is fully in communication with the external environment, for example, the second vent hole 912 is directly opposite the first vent hole 12. The first position can refer to the position where the sheath 91 is sleeved on the needle body 1 and the root of the sheath 91 abuts against the limiting member 92 when the limiting member 92 is installed on the needle body 1. The second position can refer to the position where the tip of the sheath 91 abuts against the tip of the needle body when the limiting member 92 is removed.

[0051] In the above embodiment, before intestinal gas is expelled, the limiting member 92 is kept in the state of being installed on the needle body. During the puncture, the sheath 91 is inserted into the patient's intestine. Due to the protective function of the sheath 91 against the wall, it can prevent muscles and other objects from blocking the first vent hole 12. When venting is required after puncture, the limiting member 92 is removed, and the needle body is further inserted to eliminate the reserved set distance. At this time, the first vent hole 12 and the second vent hole 912 are aligned, and the gas accumulated in the intestine can be discharged.

[0052] In some embodiments, refer to Figure 3 A limiting block 14 is fixedly installed on the outer wall of the needle body 1, and a limiting groove 913 is provided on the outer wall of the sheath tube 91. The limiting groove 913 extends along the axial direction of the sheath tube 91 and corresponds to the limiting block 14. The two circumferential side walls of the limiting block 14 are respectively attached to the two circumferential side walls of the limiting groove 913. The sliding distance of the limiting block 14 in the limiting groove 913 is not less than a set distance. The limiting groove 913 provides guidance for the movement of the limiting block 14 and the needle body 1, preventing relative rotation between the needle body 1 and the sheath tube 91, which would cause the first exhaust hole 12 and the second exhaust hole 912 to be misaligned in the circumferential direction.

[0053] Example 4 This embodiment uses an external outer sleeve 10 for sealing. The outer sleeve 10 has a simple structure, low cost, convenient operation, and reliable sealing effect. (Refer to...) Figure 5 The anti-clogging element includes an outer sleeve 10, which is fitted onto the outside of the needle body 1. The outer sleeve 10 and the needle body 1 are slidably connected along the axis of the needle body 1. The inner wall of the outer sleeve 10 serves as an anti-clogging wall surface, which can cover and block the first vent holes 12 to prevent clogging. The first position can refer to the position where the outer sleeve 10 completely covers all the first vent holes 12, and the second position can refer to the position where the outer sleeve 10 slides towards the second end of the needle body until it no longer blocks any of the first vent holes 12.

[0054] In the above embodiment, when the outer tube 10 slides to the first position, the outer tube 10 covers the first vent hole 12; when the outer tube 10 slides to the second position, the first vent hole 12 communicates with the external environment of the needle body 1, allowing intestinal gas to flow into the venting cavity through the first vent hole 12.

[0055] In the above embodiment, the outer sheath 10 has a tapered structure on the side near the first puncture part 11. This tapered structure can effectively expand and push away the tissue during puncture, forming a smooth transition with the needle tip, thereby significantly reducing the overall resistance during needle insertion, making the puncture action smoother, and helping to reduce patient discomfort.

[0056] A pin 101 is detachably connected to the needle body 1, and the pin 101 abuts against the end of the outer tube 10 away from the first puncture part 11. During needle insertion, the pin 101 can prevent relative displacement between the outer tube 10 and the needle body. When air needs to be released, the pin 101 can be removed, and the outer tube 10 can be slid towards the needle tail to the second position.

[0057] In some embodiments, the first puncture portion 11 includes a needle tip with a tapered structure. Compared to a puncture needle with a beveled end, the tapered structure of the first puncture portion 11 in this embodiment prevents the severing of nerves or blood vessels at the puncture site, resulting in less trauma. (See reference...) Figure 6 The inner diameter of the needle body 1 can be selected as 0.4 mm, and the outer diameter can be selected as 0.5 mm. Those skilled in the art can also set the inner and outer diameter dimensions of the needle body 1 as needed, which can also achieve the effect of facilitating air release and reducing stinging sensation, without departing from the spirit of the present invention.

[0058] Multiple first exhaust holes 12 are provided, which are staggered, equally spaced, or irregularly arranged. This arrangement facilitates the rapid discharge of accumulated air at different heights and in different horizontal directions, thus improving exhaust efficiency. The acupuncture device also includes a needle handle 4, which is fixedly located near the second end of the needle body 1. The needle handle 4 is easy for the user to grip.

[0059] In some embodiments, refer to Figure 7 and Figure 8 The acupuncture device also includes a catheter 5 and a negative pressure bottle 6. The first end of the catheter 5 is fixedly connected to the second end of the needle body 1, and the second end of the catheter 5 is used to communicate with the negative pressure bottle 6. The negative pressure bottle 6 has an interface 7 and a pressure gauge 8. The interface 7 is used to communicate with the catheter 5, and the pressure gauge 8 is used to display the pressure inside the negative pressure bottle 6. The negative pressure bottle 6 can provide negative pressure. After the interface 7 is connected to the catheter 5, the accumulated gas in the intestine can be quickly sucked out under the action of negative pressure. The negative pressure bottle 6 can also control the volume of gas discharged, and the pressure gauge 8 can display the negative pressure value inside the negative pressure bottle 6 in real time.

[0060] The negative pressure bottle 6 can be selected in volumes of 100ml, 200ml, and 500ml, with different specifications of negative pressure bottle 6 chosen to accommodate different amounts of intestinal gas. During use, the needle 1, equipped with an anti-clogging element, is inserted into the distended intestinal tract. The appropriate volume of negative pressure bottle is then connected to the catheter. Negative pressure draws intestinal gas through the first vent hole into the venting cavity. The gas then travels along the needle and catheter into the negative pressure bottle. The operation is complete when the pressure gauge on the negative pressure bottle reaches zero.

[0061] Reference Figure 9 Normally, the inner diameter of the human colon is about 5 cm. When a tumor blocks the flow of gas or when there is intestinal adhesion and obstruction, the contents of the intestine cannot be expelled, leading to intestinal distension, intestinal dilation, and thinning of the abdominal and intestinal walls. The patient feels as if their abdomen is about to burst. Figure 9 CT scan of the mid-abdomen.

[0062] If there is no clear indication for surgery at this time, the patient needs to continue conservative treatment, such as conventional acupuncture at acupoints on the limbs like Zusanli, which indirectly promotes intestinal peristalsis, but the effect is poor. Even when using direct needling at acupoints on the abdomen like Zhongwan, ordinary acupuncture needles are solid and cannot achieve the effect of gas expulsion.

[0063] The acupuncture device in this embodiment is applied as follows: Select the area near the Zhongwan acupoint on the abdomen. Under ultrasound guidance, determine the safe position and depth for acupuncture. After disinfecting and drying the skin surface, perform aseptic procedures. Insert the needle 1, equipped with an anti-blocking element, into the distended intestinal tract. Remove the anti-blocking element. Connect an appropriate volume negative pressure bottle to the catheter. Negative pressure draws intestinal gas through the first vent into the venting cavity. The gas then travels along the needle and catheter into the negative pressure bottle. The operation is complete when the pressure gauge on the negative pressure bottle reaches zero. The operation time is controlled within 3 minutes. Remove the needle, apply pressure with a dry cotton ball for 10 minutes, and then apply a sterile dressing. This acupuncture device is disposable and poses no risk of cross-infection.
