[0002] In the field of pneumothorax treatment, the use of traditional pneumothorax needles indeed faces a series of challenges, especially in the use of puncture needles and the efficiency of gas exhaust. During the gas exhaust process, the traditional pneumothorax needle often needs to be pulled out, which not only increases the complexity of the operation of medical personnel but also brings potential safety hazards.

[0003] Specifically, when the puncture needle is pulled out, a temporary channel is formed between the chest cavity and the external environment. If this channel is not properly managed and protected, it may lead to the entry of external air, bacteria or other contaminants into the chest cavity, thereby increasing the risk of infection. For patients, this is undoubtedly an additional threat that may prolong the treatment time and even affect the recovery process.

[0004] In addition, due to the limitations of the design of traditional pneumothorax needles, their gas exhaust efficiency is often low. This means that during the treatment process, medical personnel need to spend more time to exhaust the gas in the chest cavity to achieve the treatment effect. This not only increases the pain of patients because the long gas exhaust process may make patients feel uncomfortable and anxious, but also reduces the utilization efficiency of medical resources.

[0035] The specific implementation of the present application is described below with reference to the accompanying drawings.

[0036] Referring to Figs. 1-3 The technical scheme of the present application provides an efficient pneumothorax needle, which has a delicate structure design and aims to provide a medical device capable of accurately controlling the exhaust volume, effectively preventing gas backflow, being easy to operate and significantly reducing patient pain.

[0037] As Figs. 1-3 shown, specifically, the only exhaust pneumothorax needle of the present application is mainly composed of a valve pipe 100, a catheter assembly 200, a puncture needle assembly 300, a sealing part 400 and a one-way valve assembly 500. The valve pipe 100 serves as the main part of the entire device, and has a gas guide pipe 101 inside, which extends along the axial direction of the valve pipe 100 and has both ends designed as open to facilitate the circulation of gas. The catheter assembly 200 is tightly and fixedly connected with the valve pipe 100, and its internal cavity is kept in the same straight line with the gas guide pipe 101, ensuring the smoothness of gas flow. The one-way valve assembly 500 is installed on the side wall of the valve pipe 100 and is in communication with the gas guide pipe 101, realizing the one-way discharge of gas and effectively preventing the backflow of external gas. The puncture needle assembly 300 is movably arranged in the cavity of the catheter assembly 200 and is used for puncturing the thoracic cavity of the patient to perform exhaust operation. The sealing part 400, as a key component, is detachably connected to the valve pipe 100 and is used to close the end of the gas guide pipe 101 when the puncture needle assembly 300 is retracted.

[0038] The outer surface of the valve pipe 100 is provided with anti-slip texture, which facilitates the holding and operation of medical personnel and reduces the risk of accidents caused by slippery hands. The inner wall of the gas guide pipe 101 is smooth to reduce the resistance of gas flow and improve the exhaust efficiency. A one-way valve hole 102 is specially provided on the side wall of the gas guide pipe 101, which is tightly connected with the one-way valve assembly 500 and is the only channel for gas discharge. The design of the one-way valve hole 102 needs to be accurately calculated to ensure sufficient exhaust volume and avoid gas leakage caused by excessive size.

[0039] As Fig. 2As shown, the catheter assembly 200 in the embodiment is composed of an outer sleeve 201 and several auxiliary components, which is a guide channel for the puncture needle assembly 300 to pierce into the patient's chest. The outer sleeve 201 is made of transparent or translucent material, which is convenient for medical staff to observe the situation during the puncture process. One end of the outer sleeve 201 is tightly and fixedly connected with the valve pipe 100, which ensures that the gas cannot leak from the connection. The other end is designed to be a closed shape and close to the insertion part 202 of the puncture needle 301, so as to reduce the resistance during puncture and prevent external pollutants from entering. A plurality of exhaust holes 203 are arranged on the side wall of the outer sleeve 201, which can assist in exhaust and improve exhaust efficiency during the puncture process. In addition, clear scale lines are engraved on the outer sleeve 201, so that medical staff can accurately judge the insertion depth of the puncture needle 301 according to the scale lines, and ensure the accuracy of treatment.

[0040] As shown in the drawings, Fig. 3 The puncture needle assembly 300 in the embodiment is one of the core components of the utility model. The puncture needle 301 is made of medical-grade stainless steel, which is smooth and sharp on the surface, so as to reduce the resistance during puncture and alleviate the pain of the patient. The diameter of the puncture needle 301 gradually decreases from top to bottom, which makes the puncture needle gradually reduce the damage to the tissue when it pierces into the patient's chest, and at the same time, when the puncture needle 301 is retracted into the catheter assembly 200, the flow space of the gas is increased, and the exhaust efficiency is improved. On the outer side wall of the puncture needle 301, a limiting protrusion 303 in the shape of a ring and with a circular cross section is fixedly connected, which is used in cooperation with the sealing part 400 to realize the sealing of the end of the air duct 101. The non-tipped end of the puncture needle 301 is connected with the hand-held part 302, and a female connector on the hand-held part 302 is threadedly connected with the male connector 103 at the end of the valve pipe 100, so that the puncture needle assembly 300 and the valve pipe 100 can be tightly connected or disassembled by rotating the hand-held part 302.

[0041] As shown in the drawings, Fig. 2 The sealing part 400 in the embodiment not only ensures the sealing of the end of the air duct 101, but also facilitates the entry and exit of the puncture needle assembly 300. The sealing part 400 is made of soft and good sealing material such as silica gel, which can tightly fit the inner wall of the puncture needle 301 and the air duct 101. A passage is arranged in the sealing part 400, which is communicated with the air duct 101. The diameter of the middle part of the passage is smaller than the diameter of the upper and lower openings of the passage, and the diameter of the upper and lower openings of the passage is smaller than the diameter of the puncture needle 301. This design makes the limiting protrusion 303 able to be clamped into the passage of the sealing part 400 when the puncture needle assembly 300 is retracted into the lumen, so as to realize the tight sealing of the end of the air duct 101. When the puncture needle assembly 300 exits, it can easily pass through the passage of the sealing part 400 without causing damage to it.

[0042] Meanwhile, since the sealing part 400 is made of flexible material, on one hand, the sealing effect is improved, so that exhaust can only be carried out through the one-way valve assembly 500; on the other hand, when it is necessary to drain liquid, the flexible sealing part 400 can pull out the puncture needle assembly 300 after being pulled by a large force, so that liquid can also be drained, and the sealing part 400 is detachably arranged on the side wall of the valve pipe 100, so that it can be replaced after long-term wear and tear, and the inside of the valve pipe 100 can also be conveniently cleaned and disinfected through the sealing part 400.

[0043] As shown in Fig. 2 , the one-way valve assembly 500 in the embodiment is a key component for realizing one-way exhaust of gas. The one-way valve assembly 500 is made of medical-grade material and has good corrosion resistance and durability. The one-way valve assembly 500 is internally provided with a valve core and a valve seat and the like. When the gas pressure in the thoracic cavity is greater than the external pressure, the valve core will be pushed away, allowing the gas to be exhausted through the one-way valve assembly 500. When the external pressure is greater than the gas pressure in the thoracic cavity, the valve core will be tightly pressed against the valve seat, preventing the gas from flowing back. The design of the one-way valve assembly 500 needs to ensure the sensitivity and stability of its opening and closing, so as to avoid treatment failure due to jamming or failure of the valve core.

[0044] In another embodiment, as shown in Fig. 3 , the puncture needle 301 is provided with a needle hole, and the side wall of the puncture needle 301 is further provided with a plurality of gas outlet holes 304 which are in the same plane and are annularly distributed. When the limiting protrusion 303 is engaged into the channel of the sealing part 400, the gas outlet holes 304 are in the same plane as the one-way valve hole 102, so as to further improve the exhaust effect. When the puncture needle 301 is retracted into the catheter assembly 200, the needle hole and the gas outlet hole 304 of the puncture needle 301 can also be beneficial to improve the exhaust effect.

[0045] In use of the only exhaust air needle of the utility model, medical staff first installs the suitable puncture needle assembly 300 according to the specific condition of the patient. The female joint on the hand-held part 302 is matched with the male joint 103 at the end of the valve pipe 100, the fastening connection of the puncture needle assembly 300 and the valve pipe 100 is realized. Then, the whole device is aimed at the thoracic cavity part of the patient, after confirming no mistake, the hand-held part 302 is pushed with force, the puncture needle 301 passes through the passage of the outer sleeve tube 201 and the sealing part 400, and is stabbed into the thoracic cavity of the patient, the insertion depth of the puncture needle 301 is judged through the scale line on the outer sleeve tube 201. Then the hand-held part 302 is unscrewed, the puncture needle assembly 300 is pulled out a section outward, the limiting protrusion 303 is clamped to the sealing part 400, so that the end of the air guide pipe 101 is sealed, at this time, the gas in the thoracic cavity will enter the air guide pipe 101 through the needle hole in the puncture needle 301 and the air outlet hole 304 on the side wall, and is discharged through the one-way valve hole 102 and the one-way valve assembly 500. Medical staff can judge whether the gas in the thoracic cavity has been completely discharged by observing the exhaust condition of the one-way valve assembly 500.

[0046] The utility model discloses a precise cooperation of the one-way valve assembly 500 and the air guide pipe 101, and the sensitive design of the valve core and the valve seat in the one-way valve, which ensures that when the gas pressure in the thoracic cavity reaches a certain degree, the valve core is automatically opened to allow a proper amount of gas to be discharged, and when the external pressure is greater than the pressure in the thoracic cavity, the valve core is tightly closed to prevent gas backflow. This design not only ensures the accuracy of the exhaust, but also greatly improves the safety of the treatment, avoids complications caused by improper exhaust, such as subcutaneous emphysema and atelectasis, and thus improves the overall treatment effect, enabling the patient to recover faster and more safely.

[0047] The only exhaust air needle of the utility model has many advantages and characteristics. First of all, it is designed ingeniously, simple in structure and easy to operate, and medical staff can easily master the use method. Secondly, through the design of the one-way valve assembly 500, the one-way discharge of gas is realized, effectively preventing the backflow of external gas and improving the safety of treatment. Thirdly, the movable design of the puncture needle assembly 300 enables medical staff to flexibly adjust the puncture depth according to the specific condition of the patient, improving the accuracy of treatment. In addition, the ingenious design of the sealing part 400 not only ensures the sealing of the end of the air guide pipe 101, but also facilitates the entry and exit of the puncture needle assembly 300, improving the convenience of use. Finally, the whole device is made of medical-grade materials, has good corrosion resistance and durability, and ensures the long-term effectiveness of the treatment.

[0048] The only exhaust pneumothorax needle of the utility model is widely applicable to various pneumothorax treatment scenes needing exhaust, such as spontaneous pneumothorax, traumatic pneumothorax and the like. The functions of accurately controlling exhaust volume and preventing gas backflow enable medical staff to more effectively treat patients and reduce the pain of patients. Meanwhile, the only exhaust pneumothorax needle of the utility model can also be expanded and improved according to actual needs. For example, a pressure monitoring device can be additionally arranged on the one-way valve assembly 500 to monitor the gas pressure change in the thoracic cavity in real time; or an illumination device can be additionally arranged on the outer sleeve tube 201 to provide a better vision for medical staff and the like. These expansions and improvements will further improve the practicability and application value of the utility model.

[0049] To sum up, the only exhaust pneumothorax needle of the utility model realizes the goals of accurately controlling exhaust volume, effectively preventing gas backflow, being easy to operate and significantly reducing the pain of patients through a series of ingenious designs and innovative technical solutions. The unique structural design, excellent performance and wide application scenarios enable the utility model to have a broad market prospect and great development potential in the field of pneumothorax treatment.
