Description

Technical Field

[0001] This utility model relates to the field of catheter connector technology, and in particular to a PICC catheter anti-pressure injury connector. Background Technology

[0002] Peripherally inserted central venous catheters (PICCs) are widely used in clinical treatment due to their ease of operation, safety, and ability to effectively reduce the pain caused by repeated punctures. During the use of PICCs, the connector is a key component that not only serves to fix the catheter but also provides necessary protection for the catheter connector and tubing to prevent damage from external factors. At the same time, while ensuring the connector is stable, it is important to avoid pressure injuries to the patient's skin caused by improper fixation.

[0003] In current medical settings, some PICC catheter connectors use simple adhesive tape or a single clamping device to secure the catheter. When using adhesive tape, the tape adheres tightly to the patient's skin, securing the catheter. This method is simple to operate, and medical staff can easily learn it without complex training. The clamping device, on the other hand, relies on a mechanical locking principle. The catheter can be inserted into a pre-set slot, the shape of which is adapted to the diameter of the catheter. By using the clamping device's structure to restrict the catheter's movement in the horizontal and vertical directions, a relatively stable fixation of the catheter is achieved, meeting the basic fixation requirements of PICC catheters.

[0004] Existing PICC catheter connectors, in practical use, cannot simultaneously ensure the stability of catheter fixation, protection of the patient's skin, and comprehensive protection of the catheter and connector. Due to the limitations of the fixation method, the catheter often becomes unstable, easily shifting or even falling off. This not only affects the smooth progress of intravenous infusion therapy but also increases the risk of infection for the patient. At the same time, the catheter directly contacts and compresses the patient's skin, and prolonged use can lead to skin redness, pain, or even damage, seriously affecting the patient's comfort. Therefore, a PICC catheter pressure injury prevention connector is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a PICC catheter anti-pressure injury connector, which aims to improve the problem of catheters directly compressing the skin, causing discomfort to patients and catheter instability in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PICC catheter anti-pressure injury connector includes a flexible plate with multiple vent holes arranged in an array inside the flexible plate. A binding component is provided on the side of the flexible plate, and a fixing box is fixedly connected to the top of the flexible plate. A fixing component is provided inside the fixing box.

[0008] The fixing assembly includes left and right symmetrical fixing plates. The bottom of the fixing plates is fixedly connected to the bottom of the inner wall of the fixing box. The fixing plates are rotatably connected to left and right symmetrical clamping rings inside each fixing plate. The side walls of each clamping ring are fixedly connected to connecting plates. The bottom of each connecting plate is provided with a return spring. One end of the return spring is fixedly connected to the bottom of the connecting plate, and the other end of the return spring is fixedly connected to the top of the fixing plate.

[0009] As a further description of the above technical solution:

[0010] The binding component includes symmetrical binding straps, the sidewalls of which are fixedly connected to the sidewalls of the flexible board, and each end of the binding strap is provided with Velcro.

[0011] As a further description of the above technical solution:

[0012] The fixing box has tube placement ports on both the left and right sides for placing conduit wires. The fixing box has a cover on the top. The fixing box and the cover are fixedly connected to the side walls of the fixing box and the cover, and the connecting shaft is used to connect the fixing box and the cover.

[0013] As a further description of the above technical solution:

[0014] An anti-slip strip is fixedly connected to the side wall of the lid, and the anti-slip strip is used to provide friction when opening the lid.

[0015] As a further description of the above technical solution:

[0016] A locking block is provided at the bottom of the box lid, and the top of the locking block is fixedly connected to the bottom of one side of the box lid.

[0017] As a further description of the above technical solution:

[0018] The bottom of the locking block is provided with a locking box, and the outer wall of the locking box is fixedly connected to the inside of the fixing box.

[0019] As a further description of the above technical solution:

[0020] The locking box is equipped with limit balls on the left and right sides inside, and the outer walls of the limit balls are slidably connected to the inside of the locking box.

[0021] As a further description of the above technical solution:

[0022] Each of the limiting balls is provided with a limiting spring on its side. One end of the limiting spring is fixedly connected to the side wall of the limiting ball, and the other end of the limiting spring is fixedly connected to the inside of the locking box.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, medical staff place the catheter connector and tubing into the fixing box, pass both ends of the tubing through the insertion port, and then clamp the tubing into the clamping ring. Subsequently, the medical staff place the soft plate on the patient's skin, which achieves the effect of fixing the catheter and separating it from the skin. This solves the problem of the catheter directly pressing on the skin, causing discomfort to the patient, and the catheter being unstable, thus improving the safety and stability of catheter use.

[0025] 2. In this utility model, the locking block at the bottom of the lid is inserted into the locking box. When inserted, the bottom of the locking block squeezes the limiting ball, causing the limiting ball to move inward. The limiting spring is compressed and contracts. When the locking block is fully inserted, the limiting spring returns to its original position, pushing the limiting ball into the recesses on both sides of the locking block, thus completing the lid closing. This achieves the effect of protecting pipelines and connectors, solving the problem that pipelines and connectors are easily affected by external collisions and contamination, and improving the protective performance.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a PICC catheter anti-pressure injury connector, comprising a flexible plate 1, which is made of a soft and biocompatible material such as medical-grade silicone, and has good flexibility and conformability, which can closely conform to the patient's limb skin, reduce irritation to the patient's skin, and avoid pressure on the PICC catheter. The flexible plate 1 has multiple ventilation holes 2 inside, which are made by mechanically punching holes in the flexible plate 1 during the production process. The function of the ventilation holes 2 is to ensure air circulation at the contact area between the flexible plate 1 and the patient's skin, prevent the skin from becoming stuffy and moist due to prolonged contact, and reduce the risk of complications such as pressure sores. The ventilation holes 2 are distributed in an array inside the flexible plate 1. A binding component is provided on the side of the flexible plate 1, which is used to fix the connector to the patient's limb. A fixing box 5 is fixedly connected to the top of the flexible plate 1. The fixing box 5 is made of medical-grade plastic, which can provide installation space for the fixing component and protect the catheter connector and tubing from external impact and compression. The fixing box 5 is provided with a fixing component, which is used to fix the connector and tubing of the PICC catheter.

[0034] The fixing assembly includes symmetrical fixing plates 10. The fixing plates 10 provide a mounting base for components such as clamping rings 11, connecting plates 12, and return springs 13, and limit their range of motion. The bottom of the fixing plates 10 is fixedly connected to the bottom of the inner wall of the fixing box 5. Symmetrical clamping rings 11 are rotatably connected inside each fixing plate 10. The clamping rings 11 are made of plastic with silicone embedded in their inner walls for anti-slip properties and to prevent damage to the conduit. The function of the clamping rings 11 is to clamp the conduit, fixing it within the fixing box 5 and preventing it from shaking or falling off. The side walls of the clamping rings 11 are also fixedly connected to… A connecting plate 12 is provided to connect the clamping ring 11 and the return spring 13, transmitting the rotational displacement of the clamping ring 11. Each bottom of the connecting plate 12 is equipped with a return spring 13. The function of the return spring 13 is to store elastic potential energy when the clamping ring 11 is squeezed and rotated by external force, and to release the elastic potential energy when the external force disappears, pushing the clamping ring 11 back to its initial position, thus achieving stable clamping of the catheter. One end of the return spring 13 is fixedly connected to the bottom of the connecting plate 12, and the other end of each return spring 13 is fixedly connected to the top of the fixing plate 10. The binding assembly includes symmetrical binding straps 3. 3 is made of elastic bandage, with good breathability and flexibility. The side wall of the bandage 3 is fixedly connected to the side wall of the soft plate 1. Each end of the bandage 3 is provided with Velcro 4, which consists of a hook side and a rough side, used to fix the bandage 3 to the patient's limb, so as to achieve a stable binding of the connector. The fixation box 5 has insertion ports 8 on both the left and right sides. The insertion ports 8 are formed by molding during the production of the fixation box 5. Its size is designed according to the diameter of common PICC catheters. The insertion ports 8 are used to place the catheter line and provide a channel for the catheter line to enter and exit the fixation box 5. The top of the fixation box 5 is provided with The box has a lid 6, which is made of the same medical-grade plastic as the fixation box 5. It is used to seal the fixation box 5 and protect the internal catheter connectors and tubing from dust, bacteria and other contaminants. Both the fixation box 5 and the lid 6 are fixedly connected to the side walls of the box, allowing the lid 6 to rotate around the connecting shaft 9 to open and close the fixation box 5. The connecting shaft 9 is used to connect the fixation box 5 and the lid 6. The side wall of the lid 6 is fixedly connected to an anti-slip strip 7, which is made of rubber and has a certain degree of roughness. The anti-slip strip 7 is used to provide friction for medical staff when opening the lid 6.

[0035] Specifically, when using this PICC catheter anti-pressure injury connector, the medical staff first opens the box cover 6. Holding the PICC catheter, the medical staff places the connector and tubing inside the fixing box 5. The medical staff then passes both ends of the tubing through the insertion port 8. Subsequently, the medical staff clamps the tubing between the clamps 11. The medical staff presses the clamps 11 on both sides with their fingers. Under the pressure of the medical staff's fingers, the clamps 11 rotate around the rotating connection point inside the fixing plate 10. The rotation of the clamps 11 causes the connecting plate 12 to rotate as well, which in turn causes the return spring 13 at the bottom of the connecting plate 12 to be compressed and deformed. After the tubing is fully inserted, the medical staff releases their fingers. At this time, the return spring 13, having previously been compressed and stored elastic potential energy, begins to release this elastic potential energy, pushing the connecting plate 12 to rotate. The rotation of the connecting plate 12 causes the clamping ring 11 to return to its original position, ultimately fixing the pipeline and connector, thus achieving the effect of stabilizing the catheter. After the catheter is fixed, the medical staff attaches the soft plate 1 to the patient's limb skin. Then, the medical staff picks up the strap 3 on one side and, with the patient's limb as the center, wraps it around the limb from one side to the other. Finally, the medical staff attaches the Velcro 4 at one end of the strap 3 to the corresponding part on the other side of the strap 3. The hook and loop sides of the Velcro 4 interlock, thus completing the fixation of the entire connecting seat.

[0036] Reference Figure 4 A locking block 14 is provided at the bottom of the cover 6. The locking block 14 is a plastic block with a recessed side wall. Its function is to cooperate with the locking box 15 to lock the cover 6 and the fixed box 5, preventing the cover 6 from opening accidentally and ensuring continuous protection of the PICC conduit connector and pipeline inside the fixed box 5. The top of the locking block 14 is fixedly connected to the bottom of one side of the cover 6. The locking box 15 is provided at the bottom of the locking block 14, providing installation space for the limit ball 17 and the limit spring 16, and guiding the insertion direction of the locking block 14. The outer wall is fixedly connected to the inside of the fixed box 5. Limiting balls 17 are provided on the left and right sides inside the locking box 15. Their function is to engage with the recesses on both sides of the locking block 14 when the locking block 14 is inserted into the locking box 15, fixing the locking block 14 inside the locking box 15 and locking the box cover 6 to the fixed box 5. The outer walls of the limiting balls 17 are slidably connected to the inside of the locking box 15. Limiting springs 16 are provided on the sides of the limiting balls 17. The function of the limiting springs 16 is to provide elastic force to the limiting balls 17 when the locking block 14 is inserted into the locking box 15. When the locking block 14 presses against the limiting balls 17, the limiting springs 16 are compressed and store elastic potential energy. When the locking block 14 is inserted into the correct position, the limiting springs 16 release elastic potential energy, pushing the limiting balls 17 into the recesses on both sides of the locking block 14, thus locking the box. One end of the limiting spring 16 is fixedly connected to the side wall of the limiting ball 17, and the other end of the limiting spring 16 is fixedly connected to the inside of the locking box 15.

[0037] Specifically, the medical staff then rotates the lid 6 towards the top of the fixing box 5, using the connecting shaft 9 as the central axis. From the open state, the lid 6 moves in a circular motion around the connecting shaft 9, gradually approaching the top of the fixing box 5 until the locking block 14 at the bottom of the lid 6 aligns with the entrance of the locking box 15. The medical staff continues to apply force, causing the locking block 14 at the bottom of the lid 6 to insert into the locking box 15. During insertion, the bottom of the locking block 14 contacts and presses against the limiting balls 17 on both sides. The pressing force of the limiting balls 17 against the bottom of the locking block 14... Inside the locking box 15, the locking block 14 slides inward along its sliding track. The inward displacement of the limiting ball 17 causes the limiting spring 16 to be compressed, and the elastic potential energy increases continuously. When the locking block 14 is fully inserted into the locking box 15, the recesses on both sides of the locking block 14 move to the position opposite to the limiting ball 17. At this time, the limiting spring 16, having previously been compressed and stored elastic potential energy, begins to release its elastic potential energy and pushes the limiting ball 17 into the recesses on both sides of the locking block 14, thus completing the closing operation and achieving the effect of protecting the pipeline and connector.

[0038] Working Principle: When using this PICC catheter anti-pressure injury connector, medical personnel first place the catheter connector and tubing inside the fixing box 5, and pass both ends of the tubing through the insertion port 8. Then, the medical personnel clamp the tubing between the clamping rings 11. The clamping rings 11 are compressed and rotate, causing the connecting plate 12 to rotate as well. This causes the return spring 13 at the bottom of the connecting plate 12 to compress and deform. When the tubing is fully inserted, the return spring 13 returns to its original position, pushing back the connecting plate 12, thus fixing the tubing and connector in place. This achieves the effect of stabilizing the catheter. After the tube is fixed, the medical staff attach the soft plate 1 to the patient's limb skin, wrap the strap 3 around the limb, and attach the Velcro 4 to complete the fixation of the entire connector. Then, the medical staff close the box cover 6, so that the locking block 14 at the bottom of the box cover 6 is inserted into the locking box 15. During the insertion process, the bottom of the locking block 14 presses the limiting balls 17 on both sides, causing the limiting balls 17 to move inward, which in turn causes the limiting spring 16 to be compressed. When the locking block 14 is fully inserted, the limiting spring 16 returns to its original position and pushes the limiting balls 17 into the recesses on both sides of the locking block 14, thus completing the closing operation and achieving the effect of protecting the pipeline and connector.
