[0002] In modern medicine, various types of medical tubes are widely used in the diagnosis and treatment of patients, such as infusion tubes, oxygen tubes, drainage tubes, etc. These tubes play an important role in clinical operations. They are not only related to the delivery of drugs, nutrition and oxygen, but also affect the drainage and monitoring of patients' body fluids. With the advancement of medical technology and the diversification of medical needs, the types and usage scenarios of medical tubes are increasing, and they are used more frequently in intensive care, operating rooms and general wards. However, with the increase in the number and complexity of medical tubes, their management and storage problems have gradually emerged.

[0003] Traditional medical tubing is often easily tangled together due to its long length and high flexibility, which makes operation inconvenient and increases the workload of medical staff. In the case of tangled tubing, not only does the sorting work take time, but it may also cause mechanical damage to the tubing, affecting its service life. At the same time, improperly stored tubing is prone to touch the ground or other sources of contamination, posing a risk of infection, which may adversely affect the patient's treatment effect. Especially in intensive care environments, once the complex tubing system is in disarray, it will not only reduce operating efficiency, but also significantly increase the risk of medical accidents.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] refer to Figure 1-Figure 9 , a retractable medical tube, comprising: The outer tube rack 100 includes a connecting platform a101, and a plurality of limiting vertical bars a102 are slidably connected to the connecting platform a101; An inner tube rack 103 is arranged inside the outer tube rack 100, a storage cavity 104 is formed between the outer tube rack 100 and the inner tube rack 103, the inner tube rack 103 includes a connecting platform b105 connected to the bottom of the connecting platform a101, and a plurality of limiting vertical bars b106 are connected to the bottom of the connecting platform b105; A plurality of positioning bars 107 are arranged in the inner pipe frame 103, and a positioning bar 107 is arranged between every two adjacent limiting vertical bars b106; The storage component disposed between the outer tube frame 100 and the inner tube frame 103 is used to expand and reduce the length of the storage cavity 104. The storage component can move the position of the positioning bar 107 when adjusting the length of the storage cavity 104; The storage component can move the positioning bar 107 closer to the storage cavity 104 when the length of the storage cavity 104 is expanded, and can move away from the storage cavity 104 when the length of the storage cavity 104 is reduced; By setting up the storage cavity 104, when in use, the head end of the medical tube can be inserted into the storage cavity 104, and the tube can be spirally wound in the storage cavity 104 around the annular path of the storage cavity 104, so that the tube can be stably clamped during the storage process to form a storage effect. Specifically, during the initial storage, the storage components can be used to reduce the length of the storage cavity 104 to a minimum value. At this time, the bottoms of the limiting vertical bars a102 and the limiting vertical bars b106 move toward the connecting platforms a101 and b105, and the length of the positioning bars 107 set at this time remains unchanged. The positioning bars 107 are located between two adjacent limiting vertical bars b106, forming a tube with a gap but a small gap, which is convenient for medical staff to first wind the pipelines to be stored on the outside of multiple positioning bars 107. After the winding is completed, the pipelines wound on the outside of the positioning bars 107 can be pushed, and the pipelines follow the path of the positioning bars 107 to guide the wound pipelines into the storage cavity 104 more quickly, thereby completing the pipeline storage process. In addition, when the pipeline is stored to the end position of the reduced storage chamber 104, the storage component can be used to gradually expand the length of the storage chamber 104, so as to facilitate the gradual and uniform storage of the pipeline in the entire storage chamber 104. In addition, when the length of the storage chamber 104 is expanded, the positioning bar 107 can move toward the storage chamber 104, contact the stored pipeline, and position the pipeline, thereby avoiding the phenomenon that the stored pipeline is loose due to the expansion of the storage chamber 104 affecting the stored pipeline. The storage chamber 104 can not only effectively accommodate more pipelines during the expansion process, but also perform secondary positioning and support on the stored pipeline through the dynamic adjustment of the positioning bar 107, thereby maintaining the compactness of the arrangement of the pipeline and preventing problems such as loosening, overlapping or sliding. During the movement, the positioning strip 107 contacts the stored pipeline and forms a slight compression effect. This design can ensure that the pipeline is still stably distributed in the storage cavity 104 after expansion, and prevent the pipeline from shifting due to gravity or external vibration. At the same time, the expansion operation of the storage component can be completed by precise control to meet the needs of medical pipelines of different lengths. This flexible adjustment method not only improves the scope of application of the storage device, but also further improves the efficiency and convenience of pipeline management. For pipelines that need to be frequently adjusted or replaced, medical staff can quickly expand the storage cavity 104, directly remove or re-store the pipeline, thereby significantly reducing the operation time. The present application can effectively solve the problems of inconvenient storage, entanglement and cross contamination of medical pipelines, and at the same time, through its unique dynamic adjustment function, it improves the efficiency and safety of pipeline management. This innovative design is of great significance for improving the efficiency of medical operations, reducing the work pressure of medical staff and improving patient safety, and is suitable for being widely used in hospital operating rooms, intensive care units and general wards.

[0023] The present application sets a storage chamber 104, and when in use, the head end of the medical pipeline is plugged into the storage chamber 104, and the pipeline is spirally wound in the storage chamber 104 around the annular path of the storage chamber 104, so that the pipeline can be stably clamped during the storage process, forming a good storage effect. By using the storage component to reduce the length of the storage chamber 104, the length of the storage chamber 104 is adjusted to the minimum value, and the bottom of the limit vertical bar a102 and the limit vertical bar b106 move toward the connecting platform a101 and the connecting platform b105, while the length of the positioning bar 107 remains unchanged and is between two adjacent limit vertical bars b106, so that it is convenient for medical staff to first wind the medical pipeline around the outside of multiple positioning bars 107. After the pipeline is wound, by pushing the pipeline wound around the outside of the positioning bar 107, the pipeline is guided into the storage chamber 104 along the path of the positioning bar 107, thereby realizing a fast and convenient storage operation.

[0024] In addition, when the pipeline is stored to the end of the reduced storage cavity 104, the storage component can gradually expand the length of the storage cavity 104, so that the pipeline is gradually and evenly stored in the entire storage cavity 104. During the expansion process, the positioning bar 107 can move toward the storage cavity 104, contact the stored pipeline and form a slight compression effect, perform secondary positioning and support on the pipeline, thereby effectively preventing the pipeline from loosening, overlapping or sliding due to gravity or external vibration, and ensuring the compactness and stability of the pipeline arrangement after storage.

[0025] The expansion operation of the storage component of the present application can be precisely controlled to meet the requirements of medical pipelines of different lengths, significantly improving the application range of the device and the efficiency of pipeline management. For pipelines that need to be frequently adjusted or replaced, medical staff can quickly expand the storage cavity 104 to directly complete the removal or re-storage operation of the pipeline, reducing working time and labor intensity.

[0026] Through the above design, this application effectively solves the problems of entanglement, cross contamination and inconvenience in the storage process of medical tubes, and further improves the safety and convenience of tube management through dynamic adjustment function. This innovative design helps to improve the efficiency of medical operations, reduce the work pressure of medical staff, and effectively improve the safety of patients during treatment. It is suitable for wide application in medical scenarios such as hospital operating rooms, intensive care units and general wards.

[0027] As a further solution of the present invention, the bottom of the limiting vertical bar b106 is connected to the limiting boss 108; By setting the limiting boss 108, the limiting boss 108 protrudes toward the limiting vertical bar a102, and a gap smaller than the diameter of the pipeline is formed between the two, which is convenient for the subsequent limiting of the end of the pipeline after the pipeline is stored, effectively preventing the pipeline from loosening or slipping after storage, and cooperating with the positioning bar 107 to ensure that the pipeline always maintains a stable storage state. In addition, the limiting boss 108 can also play a role in guiding the pipeline, which is convenient for medical staff to use the inclination angle of the bottom of the limiting boss 108 to push the pipeline into the storage cavity 104 when pushing the pipeline, effectively reducing the operation delay caused by resistance or jamming, and further improving the convenience and operation efficiency of pipeline storage.

[0028] As a further solution of the present invention, the storage component includes a sliding plate 200 arranged at the bottom of the limiting vertical bar b106, the limiting boss 108 is connected to the bottom of the sliding plate 200, and a connecting frame 201 is provided in the connecting platform a101, and a lead screw 202 is connected to the connecting frame 201, and a moving frame 203 connected to the sliding plate 200 is threadedly connected to the lead screw 202; By setting the sliding plate 200, the limiting vertical bar b106 and the sliding plate 200 together form a long strip structure adapted to the length of the limiting vertical bar a102. During use, the movable frame 203 is driven to move along the axial direction of the thread of the screw 202 by rotating the screw 202, thereby driving the sliding plate 200 to achieve a smooth upward movement. In this process, the limiting boss 108 can move synchronously with the sliding plate 200, thereby playing a role in pushing the end pipeline of the storage chamber 104. This design can effectively compress the pipeline in the storage chamber 104, making its arrangement more compact. The pushing effect of the limiting boss 108 can optimize the space utilization inside the storage chamber 104, avoid gaps or overlaps of the pipeline in the storage chamber 104, and help maintain the stability and neatness of the pipeline arrangement.

[0029] As a further solution of the present invention, a connecting rod a204 is connected to one side of the limiting vertical bar b106, a connecting rod b205 is slidably connected to one side of the connecting rod a204, a spring a206 is provided between the connecting rod a204 and the connecting rod b205, and a limiting shaft 207 connected to the sliding plate 200 is slidably connected to the bottom of the connecting rod b205; By setting the limit shaft 207, the cooperation between the limit shaft 207 and the connecting rod b205 can effectively limit the rotation of the sliding plate 200, ensuring that the sliding plate 200 only produces a smooth movement in the vertical direction when the lead screw 202 rotates, and the sliding plate 200 will not be deflected or rotated unnecessarily due to the rotation torque of the lead screw 202. The design of the spring a206 provides a certain elastic adjustment ability, which can avoid the position of the limit vertical bar b106 when the sliding plate 200 moves upward, and after the subsequent storage chamber 104 is fully expanded, it is ensured that a flat contact surface can be formed between the sliding plate 200 and the limit vertical bar b106, avoiding the unstable arrangement of the pipeline in the storage chamber 104 due to uneven structure.

[0030] As a further solution of the present invention, the mobile frame 203 includes a connecting rod 208 slidably connected to the mobile frame 203, and a spring b209 is connected between the connecting rod 208 and the mobile frame 203; By providing the spring b209 , the elastic adjustment function of the spring b209 can adapt to the slight lateral displacement of the sliding plate 200 .

[0031] As a further solution of the present invention, the storage component includes a synchronization rod 300 connected to the bottom of the limiting vertical bar a102, the synchronization rod 300 passes through the connection platform a101 and the connection platform b105 and extends to one side of the sliding plate 200, and one side of the sliding plate 200 is connected to a connection platform 301 slidably connected to the synchronization rod 300; By setting the synchronization rod 300, when the sliding plate 200 moves, it can achieve synchronous movement with the limiting vertical bar a102, thereby effectively expanding or shortening the length of the storage chamber 104. Specifically, when the lead screw 202 drives the sliding plate 200 to move in the vertical direction, the synchronization rod 300 also moves accordingly, thereby causing the limiting vertical bar a102 to move synchronously. Through the action of the synchronization rod 300, the limiting vertical bar a102 can maintain a consistent movement trajectory with the sliding plate 200, ensuring that the length of the storage chamber 104 can be expanded or shortened when needed. For example, in the process of storing the pipeline, when the sliding plate 200 moves upward, the limit vertical bar a102 is also driven upward with the movement of the synchronization rod 300, and the length of the storage chamber 104 is shortened. When the length of the storage chamber 104 needs to be reduced, the sliding plate 200 moves downward, and the limit vertical bar a102 also moves downward synchronously to achieve the expansion of the storage chamber 104. This synchronous movement mechanism ensures the coordinated work of the limit vertical bar a102 and the sliding plate 200, making the length change of the storage chamber 104 more accurate, avoiding the incoordination problem caused by adjusting the movement of the limit vertical bar a102 or the sliding plate 200 alone, thereby improving the stability and reliability of the overall device. In this way, the storage component can flexibly adjust the size of the storage chamber 104 to meet the storage requirements of different pipeline lengths, effectively improving the storage efficiency and management convenience of the pipeline.

[0032] As a further solution of the present invention, a traction rod 302 is connected to one side of the positioning bar 107, and the traction rod 302 is slidably connected to the connecting frame 201. A spring c303 is connected between the connecting frame 201 and the traction rod 302. A plurality of traction wheels 304 are connected to the connecting frame 201. A traction rope 305 is connected to one side of the traction rod 302. The traction rope 305 passes through the traction wheel 304 and is connected to the top of the lead screw 202. By setting the traction rod 302, the traction rod 302 is connected to the connecting frame 201 by sliding, and the traction rope 305 is passed through the traction wheel 304 and connected to the top of the lead screw 202. When the lead screw 202 rotates forward and the length of the storage chamber 104 is reduced, the traction rope 305 pulls the positioning bar 107 through the traction rod 302, so that the positioning bar 107 moves away from the storage chamber 104 along a predetermined track. When the lead screw 202 rotates forward to expand the length of the storage chamber 104, the spring c303 releases its stored potential energy, so that the traction rod 302 and the positioning bar 107 are reset under the elastic action of the spring, thereby squeezing and positioning the stored pipeline, ensuring that the pipeline remains stable and evenly distributed in the storage chamber 104, and avoiding the pipeline from being loose or disordered.

[0033] As a further solution of the present invention, a connecting shaft 400 is connected to the top of the lead screw 202, and the connecting shaft 400 is rotatably connected to the connecting frame 201. A connecting opening 401 is provided on the connecting shaft 400, and a connecting ring 402 is provided in the connecting opening 401. A traction roller 403 is provided outside the connecting ring 402, and a traction rope 305 is connected to the traction roller 403. A push rod 404 is slidably connected to the traction roller 403, and a spring d405 is connected between the push rod 404 and the traction roller 403. A top groove 406 adapted to the push rod 404 is provided on the outer wall of the connecting ring 402, and the top groove 406 is a semi-spherical groove, and one end of the push rod 404 adapted to the top groove 406 is semi-spherical, and a ratchet mechanism 407 is provided between the connecting ring 402 and the connecting opening 401; By setting the top rod 404, the top rod 404 can cooperate with the top groove 406 through the spring d405 and form a certain friction force. When the lead screw 202 rotates in the forward direction, the friction between the ratchet mechanism 407, the connecting ring 402, the top rod 404 and the top groove 406 can rotate the traction roller 403. When the traction rod 302 and the positioning bar 107 are pulled by the traction rope 305 to move, the spring c303 is compressed to generate potential energy. When the spring c303 is compressed to a preset value, the force of the spring d405 can be overcome, the top groove 406 and the top rod 404 are separated, and the connecting ring 402 can rotate inside the traction roller 403. While ensuring that the positioning rod can move and will not move for a long distance, the lead screw 202 can continue to rotate and continue to reduce the length of the storage chamber 104. The traction roller 403 is prevented from moving for a long distance due to excessive rotation of the traction roller 403, thereby ensuring the convenience of the positioning bar 107 for storing the pipeline. In addition, the ratchet mechanism 407 can rotate the connecting ring 402 in one direction. When the screw 202 rotates in the opposite direction to expand the storage chamber 104, the traction rope 305 will be released first, and then the connecting shaft 400 can idle in the connecting ring 402, thereby achieving the purpose of allowing the positioning bar 107 to slightly squeeze the pipeline to position the pipeline when expanding the storage chamber 104.

[0034] As a further solution of the present invention, a motor 408 is connected to the connecting frame 201, and a driving shaft of the motor 408 is connected to the connecting shaft 400; By providing the motor 408 , the driving shaft of the motor 408 is directly connected to the connecting shaft 400 , thereby realizing automatic driving control of the connecting shaft 400 and the lead screw 202 .

[0035] As a further solution of the present invention, a top opening 109 is provided on the top of the connecting platform a101 and the connecting platform b105; By providing the top opening 109 , it is convenient for operators to allow the head end of the pipeline to pass through the storage cavity 104 when initially storing the pipeline, thereby optimizing the initial positioning process of the pipeline.
