Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline connector devices, and in particular relates to a device for quickly adapting and replacing a connector when a high-pressure PICC catheter is broken. Background Art

[0002] Peripherally inserted central catheters (PICCs) play an important role in clinical treatment due to their advantages of minimal trauma and long retention time. High-pressure PICC catheters, in particular, can meet the needs of complex medical operations such as high-pressure injection of contrast agents and rapid infusion of high-concentration nutrient solutions. They are widely used in scenarios such as tumor chemotherapy and treatment of critically ill patients.

[0003] However, in actual use, due to long-term indwelling in the body, PICC catheters not only have to withstand friction and bending caused by patients' daily activities, but also need to deal with repeated punctures, drug corrosion, etc., which makes catheter breakage problems frequent. Once the tube breaks, if it is not handled promptly and effectively, it will not only lead to treatment interruption, but may also cause serious complications such as drug leakage, local infection, thrombosis, phlebitis, etc. In severe cases, the catheter may even need to be removed and re-inserted, which not only increases the patient's pain and financial burden, but also increases the workload of medical staff.

[0004] At present, the traditional simple treatment method for PICC catheter breakage is adopted in clinical practice, such as manually connecting with ordinary connectors and then fixing them with tape. This method lacks reliable sealing and fixing structure. During high-pressure infusion or patient activities, leakage and tube detachment are very likely to occur, which cannot guarantee the safety of treatment and has certain shortcomings.

[0014] Furthermore, a limiting ring is provided in the connecting tube, and the limiting ring is used to limit the movement of the high-pressure PICC catheter when the high-pressure PICC catheter is inserted.

[0015] Furthermore, a sealing ring is installed on the limiting ring.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example: Refer to Figure 1-8 A high-pressure resistant PICC catheter tube broken tube quick adapter replacement joint device includes a connecting tube 1, the connecting tube 1 is provided with an inlet 101 and an outlet 102, and also includes: a plurality of groups of empty ports, which are arranged on the connecting tube 1 at equal intervals; an air bag ring 2, which is arranged in the connecting tube 1, and the outer ring wall of the air bag ring 2 is in contact with the empty ports; a movable ring 3, which is slidably connected to the connecting tube 1; a cavity 302, which is arranged in the movable ring 3; an extrusion block 304, which is slidably connected in the cavity 302, and the extrusion block 304 matches the empty ports; a spring member 303, which is fixedly connected in the cavity 302, and the other end of the spring member 303 is in contact with the extrusion block 30 4 Fixed connection; In the initial state, the squeezing block 304 in the cavity 302 is pressed against the outer wall of the connecting tube 1 under the action of the spring member 303, and one end of the broken tube of the high-pressure PICC catheter is inserted into the inlet 101. At this time, the high-pressure PICC catheter will pass through the balloon ring 2, and then the movable ring 3 is moved to move the cavity 302 above the empty port. At this time, under the action of the spring member 303, the squeezing block 304 will enter the empty port and then press against the outer ring wall of the balloon ring 2. The balloon ring 2 is squeezed and deformed accordingly, and the inner ring expands, and then squeezes the outer wall of the high-pressure PICC catheter to wrap and fix it.

[0021] Cut one end of the broken high-pressure PICC catheter tube to make the cut end horizontal and neat, then insert the cut end into the inlet 101, the catheter will pass through the balloon ring 2, and then move the movable ring 3 to move the cavity 302 above the empty opening. At this time, the spring part 303 will push the extrusion block 304 into the empty opening, and the extrusion block 304 will rest on the outer ring wall of the balloon ring 2, causing the balloon ring 2 to be squeezed and deformed, and the inner ring to expand, and then wrap the outer wall of the fixed catheter to complete the initial connection and fixation. The tight wrapping characteristics of the balloon ring 2 are used to avoid gas and liquid leakage.

[0022] A sliding block 4 is slidably connected in the remaining empty openings, one end of the sliding block 4 is located in the connecting tube 1, and multiple groups of pins are fixedly connected to one end of the sliding block 4 located in the connecting tube 1. The pins on the sliding block 4 can fix the outer wall of the high-pressure resistant PICC catheter.

[0023] After the catheter is inserted and initially fixed by the balloon ring 2, the pins on the sliding block 4 fix the outer wall of the high-pressure PICC catheter, further enhancing the connection stability and preventing the catheter from easily shifting.

[0024] A push rod 301 is fixedly connected to the movable ring 3, and a slope is provided on the sliding block 4. The hypotenuse of the slope is in contact with the push rod 301. The sliding block 4 can move in the air opening by moving the push rod 301. A connecting plate is fixedly connected to the sliding block 4, and a plurality of grooves connected to the air opening are provided on the connecting pipe 1. The connecting plate is slidably connected in the groove, and a return spring 401 is connected in the groove. The other end of the return spring 401 is connected to the connecting plate.

[0025] When the moving ring 3 is moved, the push rod 301 moves accordingly, and the push rod 301 contacts the inclined edge of the slope on the sliding block 4 and moves relative to it. By utilizing the action of the inclined surface, the push rod 301 pushes the sliding block 4 to move in the empty opening, providing power for actions such as the fixing of the catheter with the nail, thereby realizing active adjustment of the position of the sliding block 4. When the push rod 301 pushes the sliding block 4 to move, the connecting plate slides in the groove, and the reset spring 401 is stretched or compressed. When the force of the push rod 301 disappears, the elastic force of the reset spring 401 will pull the connecting plate, driving the sliding block 4 to reset, so that the sliding block 4 returns to its initial position, preparing for the next catheter fixing operation.

[0026] The movable ring 3 is rotatably connected to a rotating ring 5, which is provided with a plug with an external thread. The connecting pipe 1 is fixedly connected to a locking ring 6, which is provided with a socket with an internal thread, and the socket matches the plug.

[0027] When the movable ring 3 moves to the appropriate position and completes the preliminary fixation of the airbag ring 2, the sliding block 4 and the like on the catheter, the rotating ring 5 is rotated so that the external threaded plug on the rotating ring 5 is screwed into the internal threaded socket of the locking ring 6. The fastness of the threaded connection is utilized to relatively fix the movable ring 3 on the connecting pipe 1 to ensure the stability of the catheter fixing structure and prevent the movable ring 3 from shifting and affecting the connection effect. During this process, the sliding block 4 continues to move and the rotating ring 5 enters the locking ring 6. When it is finally unable to move, the extrusion block 304 will squeeze the airbag ring 2 through the empty port.

[0028] Anti-slip grooves are provided on both the rotating ring 5 and the moving ring 3.

[0029] When the operator rotates the rotating ring 5 or moves the moving ring 3, the anti-slip pattern can increase the friction between the hand and the rotating ring 5 or the moving ring 3, making the operation more labor-saving and convenient, avoiding slipping, and facilitating the installation, fixation and catheter connection of the device.

[0030] The connecting pipe 1 is provided with a guide slope 105 on the opening for the extrusion block 304 to slide, and the extrusion block 304 is provided with a guide surface matching the guide slope 105. Through the guide surface and the guide slope 105, the extrusion block 304 can be retracted into the cavity 302 along the guide slope 105.

[0031] When the moving ring 3 drives the cavity 302 to move and the extrusion block 304 approaches the empty opening of the connecting tube 1, the guide surface contacts the guide slope 105. As the moving ring 3 continues to move, the extrusion block 304 will gradually shrink into the cavity 302 along the guide slope 105, facilitating the movement operation of the moving ring 3 and the subsequent extrusion block 304 pops out under the action of the spring to squeeze the airbag ring.

[0032] The movable ring 3 and the connecting pipe 1 are respectively provided with a magnet 1 701 and a magnet 2 702 , and the movable ring 3 can be fixed on the connecting pipe 1 through the magnet 1 701 and the magnet 2 702 .

[0033] The first magnet 701 and the second magnet 702 attract each other, and the movable ring 3 is fixed on the connecting pipe 1 by magnetic force.

[0034] A limit ring 103 is provided in the connecting tube 1 . The limit ring 103 is used to limit the movement of the high-pressure PICC catheter when the high-pressure PICC catheter is inserted. A sealing ring 104 is installed on the limit ring 103 .

[0035] When inserting the high-pressure PICC catheter, the fracture of the high-pressure PICC catheter is cut, and the cutting surface is horizontal and neat, and then the cut catheter is passed through the inlet 101 and moved into the connecting tube 1. When the catheter cut contacts the limiting ring 103, the limiting ring 103 blocks the catheter from continuing to move, thereby limiting the moving distance of the catheter, making it convenient for the subsequent airbag ring 2, sliding block 4, etc. to fix the catheter, so that the catheter is in a suitable position in the connecting tube 1 for connection. At the same time, when the catheter is inserted and restricted by the limiting ring 103, the sealing ring 104 will fit tightly between the outer wall of the catheter and the limiting ring 103 to seal the part, preventing gas and liquid from leaking from the gap between the catheter and the limiting ring 103, thereby improving the sealing of the entire device after connection and ensuring the use effect.

[0036] Confirm whether the high-pressure PICC catheter is broken, prepare the quick-adapter replacement connector device, and check that the connecting tube 1, balloon ring 2, moving ring 3, sliding block 4, rotating ring 5, locking ring 6 and other components are not damaged and function normally.

[0037] Hold the connecting tube 1 and slowly insert one end of the broken high-pressure PICC catheter into the inlet 101 of the connecting tube 1. During the insertion process, the catheter will pass through the balloon ring 2 in the connecting tube 1. When the end of the catheter contacts the limiting ring 103 in the connecting tube 1, the limiting ring 103 limits the catheter from going deeper, so that the catheter is in a suitable connection position in the connecting tube 1. At the same time, the sealing ring 104 on the limiting ring 103 preliminarily seals the gap between the catheter and the connecting tube 1.

[0038] Push the movable ring 3 to slide along the connecting tube 1, so that the cavity 302 in the movable ring 3 moves to above the corresponding empty opening on the connecting tube 1. In the initial state, the extrusion block 304 in the cavity 302 is pressed against the outer wall of the connecting tube 1 under the action of the spring member 303. When the cavity 302 reaches the empty opening position, the spring member 303 pushes the extrusion block 304 into the empty opening, and the extrusion block 304 is pressed against the outer ring wall of the airbag ring 2.

[0039] The balloon ring 2 is deformed by extrusion, and the inner ring expands, tightly wrapping the outer wall of the high-pressure PICC catheter to achieve preliminary sealing and fixation to prevent gas and liquid leakage. During this process, the guide slope 105 on the empty opening of the connecting tube 1 cooperates with the guide surface on the extrusion block 304 to assist the extrusion block 304 in entering the empty opening smoothly. If the movable ring 3 moves back, the extrusion block 304 can also shrink into the cavity 302 along the guide slope 105.

[0040] During the movement of the movable ring 3, the push rod 301 thereon moves synchronously, and the push rod 301 contacts the sloped bevel on the sliding block 4. As the movable ring 3 continues to move, the push rod 301 uses the inclined surface to push the sliding block 4 to move in the empty opening of the connecting tube 1, so that the pin at one end of the sliding block 4 located in the connecting tube 1 is close to the catheter.

[0041] When the airbag ring 2 is initially fixed, the pins on the sliding block 4 touch the outer wall of the catheter, locking the catheter and further preventing the catheter from moving. When the sliding block 4 moves, its connecting plate slides in the groove of the connecting tube 1, and the return spring 401 in the groove is stretched or compressed. If the force of the push rod 301 disappears subsequently, the return spring 401 can drive the sliding block 4 to reset.

[0042] Turn the rotating ring 5 on the moving ring 3, and the plug with the external thread on the rotating ring 5 begins to be screwed into the internal thread socket of the locking ring 6 on the connecting pipe 1. During the rotation process, the anti-slip grooves on the rotating ring 5 and the moving ring 3 increase the friction, which facilitates the operation and enables the plug and the socket to be smoothly threaded together.

[0043] Finally, a new high-pressure PICC catheter is inserted into the outlet 102 through the thread. The new tube generally has a threaded connector, and the threaded connector can be used to achieve a stable connection between the two.

[0044] The present invention can tightly wrap and fix the outer wall of the inserted high-pressure resistant PICC catheter through the arrangement of the airbag ring 2 to prevent leakage of gas and liquid. The arrangement of the pins on the sliding block 4 can lock and fix the high-pressure resistant PICC catheter to prevent movement of the high-pressure resistant PICC catheter, thereby facilitating the rapid connection of a broken high-pressure resistant PICC catheter with a new one.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
