Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a PICC catheter protective cover. Background Art

[0002] PICC catheterization refers to the peripherally inserted central venous catheter technology, which is performed by peripheral vein puncture and cannulation. The tip of the catheter is positioned in the superior vena cava. The PICC tube is soft and has a long retention time. PICC catheterization can reduce stimulation to peripheral veins, protect blood vessels, and reduce leakage and phlebitis.

[0003] After the PICC catheter is inserted into the patient's body, the end of the PICC catheter placed outside the patient's body is usually fixed to prevent the PICC catheter from falling off during the patient's daily life and affecting the effect. At the same time, the existing protective cover is inconvenient to fix because the PICC catheter is thin and is not suitable for PICC catheters of different sizes. Therefore, a PICC catheter protective cover is proposed. Utility Model Content

[0004] The utility model discloses a PICC catheter protective cover, which is intended to solve the technical problems that the existing PICC protective cover is inconvenient to fix and is not suitable for PICC catheters of different sizes.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0006] A PICC catheter protective cover comprises a protective cover body, wherein the protective cover body is provided with PICC catheter holes running through both ends thereof, the protective cover body is provided with a fixing assembly, the fixing assembly comprises a fixing block and a control knob, the fixing block is movably connected to the inside of the protective cover body and is provided with an inclined surface, a rack is provided on the inclined surface, the control knob part extends out of the protective cover body and is rotatably connected to the side wall of the protective cover body, the control knob is provided with teeth surrounding a circle and meshing with the rack of the fixing block, and the protective cover body is provided with a limiting block on the side where the control knob extends.

[0007] When the utility model is actually used, after the medical staff completes the insertion of the PICC catheter, the section of the PICC catheter remaining outside the patient's body is passed through the PICC catheter hole of the protective cover body, and after the protective cover body is slid to a suitable position, the control knob is turned. When the control knob is turned, the rack meshed with it is driven to move. Since the rack is arranged on the inclined surface of the fixed block, and the position of the control knob does not change, the control knob will squeeze the fixed block during the movement of the fixed block, and then the fixed block will press the PICC catheter. When the PICC catheter cannot move freely in the protective cover body, the limit block is pushed, and the limit block is stuck in the gap between the two teeth of the control knob to limit the rotation of the control knob, thereby fixing the PICC catheter, and then fixing the device on the patient's skin surface. This effectively avoids the patient's PICC catheter from always detaching from the protective cover during daily activities. At the same time, the device can be used with PICC catheters of different sizes, and has a wider applicability.

[0008] Furthermore, movable blocks are fixedly arranged on both sides of the fixed block, a groove for the movable block to move is arranged inside the protective cover body, an elastic member is arranged at the bottom of the movable block, one end of the elastic member is connected to the bottom of the movable block near the PICC catheter, and the other end is slidably connected to the groove inside the protective cover body near the bottom of the PICC catheter. In the process of fixing the PICC catheter, the fixed block does not move in a single direction, but also moves toward the direction of the PICC catheter. The movable block and the groove are arranged, and the fixed block swings, resulting in a poor fixing effect.

[0009] Furthermore, a rotating shaft is provided at the center of the control knob, and both ends of the rotating shaft are rotatably connected to the inner wall of the protective cover body. In the process of rotating the control knob to fix the PICC catheter, the control knob is ensured not to move, and after the fixation is completed, the PICC catheter can also be firmly fixed inside the protective cover body.

[0010] Furthermore, both ends of the fixed block rack are fixedly provided with stoppers, which can prevent the rack of the fixed block from being separated from the control knob due to excessive rotation when the control knob is rotated, thereby causing the device to lose its fixing effect.

[0011] Furthermore, the opposite side of the control knob of the protective cover body is provided with a concave arc surface. After the PICC catheter is fixed inside the device, the device needs to be fixed to the patient's skin surface, and the concave arc surface can better fit the patient's skin and achieve a better fixing effect.

[0012] Furthermore, a detachable pad is provided on the inner concave arc surface of the protective cover body. The pad is made of water-absorbing material, which can absorb the sweat produced by the patient's skin to prevent bacteria from growing in the humid environment of sweat due to long-term fixation.

[0013] Furthermore, the shape of the pad is in line with the inner concave arc surface. The pad with the inner concave arc surface can better contact the patient's skin, with a larger contact area, so that the pressure on the patient during fixation is smaller.

[0014] Furthermore, fixing belts are arranged on both sides of the protective cover body. After the PICC catheter is fixed inside the device, the fixing belt is used to fix the device on the patient's skin surface. Compared with other fixing methods, the integrated fixing is more stable.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] (1) The protective cover body of this Zhuang fixes the PICC catheter through a fixing component. The fixing method is simple to operate and firm. It is suitable for PICC catheters of different sizes and has a wide applicability.

[0017] (2) The contact surface between the device and the patient's skin is set as a concave arc surface, and the pad with a concave arc surface is set at the contact point. When fixed, it can better fit the patient's skin and the contact area, so that the pressure on the patient's skin is less during fixation, and the patient is more comfortable; at the same time, the pad is made of absorbent material, which can absorb excess moisture to prevent bacterial growth.

[0027] Example:

[0028] like Figure 1 to Figure 3 As shown: a PICC catheter protective cover, including a protective cover body 1, the protective cover body 1 is provided with PICC catheter holes 5 running through both ends thereof, the protective cover body 1 is provided with a fixing assembly, the fixing assembly includes a fixing block 6 and a control knob 3, the fixing block 6 is movably connected to the inside of the protective cover body 1 and is provided with an inclined surface, a rack is provided on the inclined surface, the control knob 3 partially extends out of the protective cover body 1 and is rotatably connected to the side wall of the protective cover body 1, the control knob 3 is provided with teeth surrounding a circle and meshing with the rack of the fixing block 6, and the protective cover body 1 is provided with a limiting block 2 on the side where the control knob 3 extends.

[0029] When the utility model is actually used, after the medical staff completes the insertion of the PICC catheter, the section of the PICC catheter remaining outside the patient's body is passed through the PICC catheter hole 5 of the protective cover body 1, and after the protective cover body 1 is slid to a suitable position, the control knob 3 is turned. When the control knob 3 is turned, the rack meshed with it is driven to move. Since the rack is arranged on the inclined surface of the fixed block 6, and the position of the control knob 3 does not change, the fixed block 6 will squeeze the fixed block 6 during the movement, and then the fixed block 6 will press the PICC catheter. When the PICC catheter cannot move freely in the protective cover body 1, the limit block 2 is pushed, and the limit block 2 is stuck in the gap between the two teeth of the control knob 3 to limit the rotation of the control knob 3, thereby fixing the PICC catheter, and then fixing the device on the patient's skin surface. This effectively avoids the patient's PICC catheter from always detaching from the protective cover during daily activities. At the same time, the device can be used with PICC catheters of different sizes, and has a wider applicability.

[0030] The fixed block 6 is fixedly provided with movable blocks 9 on both sides, the protective cover body 1 is provided with a groove for the movable block 9 to move, and the bottom of the movable block 9 is provided with an elastic member, one end of the elastic member is connected to the bottom of the movable block 9 near the PICC catheter, and the other end is slidably connected to the groove inside the protective cover body 1 near the bottom of the PICC catheter.

[0032] Both ends of the rack of the fixing block 6 are fixedly provided with stoppers 7. The stoppers 7 can prevent the rack of the fixing block 6 from being disengaged from the control knob 3 due to excessive rotation when the control knob 3 is rotated, thereby causing the device to lose its fixing effect.

[0033] The opposite side of the protective cover body 1 where the control knob 3 is arranged is arranged as a concave arc surface. After the PICC catheter is fixed inside the device, the device needs to be fixed to the patient's skin surface, and the arranged concave arc surface can better fit the patient's skin and achieve a better fixing effect.

[0034] The inner concave arc surface of the protective cover body 1 is provided with a detachable pad 4. The pad 4 is made of a water-absorbing material, which can absorb the sweat produced by the patient's skin to prevent bacteria from growing in the moist environment of sweat due to long-term fixation.

[0035] Furthermore, the shape of the pad 4 fits the concave arc surface. The pad 4 with the concave arc surface can better contact the patient's skin, with a larger contact area, so that the pressure on the patient during fixation is smaller.
