Description

Technical Field

[0001] The utility model relates to the technical field of catheter protection patches, in particular to a breathable catheter protection patch for hemodialysis patients. Background Art

[0002] The catheter protection patch for hemodialysis patients is a specially designed patch used to protect the extracorporeal circulation catheter of hemodialysis patients and prevent catheter displacement and infection. It usually uses medical glue, can be firmly adhered to the skin, and will not cause damage to the skin when replaced. This patch can also prevent water and dirt from entering the catheter, keeping the catheter clean and dry. Hemodialysis patients can effectively reduce the occurrence of catheter-related complications and improve the treatment effect by using breathable catheter protection patches. However, the existing catheter protection patches for hemodialysis patients still have certain defects, such as:

[0003] For example, a hemodialysis catheter protective patch with a publication number of CN210904333U includes a medical patch for covering the puncture point, and an opening is provided on the medical patch for the hemodialysis catheter protective patch to extend out of the upper surface of the medical patch; a fixing patch is provided on the medical patch to adapt to the length of the hemodialysis catheter protective patch and wrap and fix the hemodialysis catheter protective patch; and a covering patch, which covers the upper surface of the medical patch and the fixing patch to waterproof the puncture point; wherein the lower surfaces of the medical patch, the fixing patch and the covering patch are all provided with an adhesive layer, and are adhered and fixed to the human skin through the adhesive layer. In this utility model, a medical patch is used to cover the puncture point, and a fixing patch is used to wrap and fix the hemodialysis catheter protective patch extending from the medical patch, so as to prevent the hemodialysis catheter protective patch from shaking, and a covering patch is adhered to the upper surfaces of the medical patch and the fixing patch to further cover the puncture point, thereby providing a double waterproof guarantee for the puncture point;

[0004] The above-mentioned hemodialysis catheter protective patch can provide double waterproof protection for the puncture point by wrapping and fixing the hemodialysis catheter protective patch extending from the medical dressing with a fixing patch. However, when the catheter protective patch is used, the protective patch is attached to the patient's skin. After a long period of adhesion, the skin is not breathable and is prone to dryness and itching, causing discomfort to the patient. At the same time, when medical staff remove the catheter, they need to press the skin, which may cause damage to the patient. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 and Figure 3 The technical solution shown in the figure, in order to solve the problem that the patient's skin is airtight, dry and itchy after the catheter protection patch is applied for a long time, discloses a breathable component: a first breathable port 2 is opened on the surface of the patch body 1, and a shell 3 is fixedly installed at the center of the upper end surface of the patch body 1, and a cover plate 4 is rotatably installed on the upper end of the shell 3, a hemodialysis catheter 6 is nested and installed inside the shell 3, a medical film 17 is fixedly installed at the bottom of the patch body 1, and a second breathable port 5 is opened at the bottom of the shell 3, and the position of the second breathable port 5 corresponds to that of the first breathable port 2;

[0033] In this example, the hemodialysis catheter 6 is placed inside the shell 3, and after the cover plate 4 is closed, the patch body 1 is aligned with the position where the patient needs to use the catheter protection patch and pasted. A first ventilation port 2 is provided on the patch body 1, and a second ventilation port 5 is provided at the bottom of the shell 3. The second ventilation port 5 at the bottom of the shell 3 corresponds to the first ventilation port 2 on the patch body 1, so that the catheter protection patch has a breathable effect when pasted, and the patient's comfort during use is improved, and it is not easy to feel stuffy. A medical film 17 is provided at the bottom of the patch body 1. The provision of the medical film 17 enables the patch body 1 to be firmly adhered to the skin and will not cause damage to the skin when replaced;

[0034] Embodiment 2:

[0035] like Figure 1-Figure 5 The technical solution shown in the figure, in order to solve the problem that the internal hemodialysis catheter 6 is easy to shake and cause discomfort to the patient when the patient uses the catheter protection patch, discloses a clamping and positioning mechanism: a knob bidirectional threaded rod 7 is rotatably installed at the bottom of the shell 3, and a clamping and positioning mechanism is provided on the surface of the knob bidirectional threaded rod 7, and the clamping and positioning mechanism can clamp the middle end of the hemodialysis catheter 6 through the rotation of the knob bidirectional threaded rod 7 to prevent it from shaking, and the clamping and positioning mechanism is provided with a movable block 8, and the connection method of the movable block 8 and the knob bidirectional threaded rod 7 is a threaded connection , and a rotating rod 9 is rotatably mounted on the upper end of the movable block 8, and a clamping plate 10 is fixedly mounted on the upper end of the rotating rod 9, the front and rear ends of the knob bidirectional threaded rod 7 have opposite threads, and the front end of the knob bidirectional threaded rod 7 penetrates the mounting housing 3, and the front end of the knob bidirectional threaded rod 7 is in the shape of a knob, a torsion spring 11 is nested and mounted on the surface of the rotating rod 9, and the upper end of the torsion spring 11 is fixedly mounted on the bottom of the clamping plate 10, and the lower end of the torsion spring 11 is fixedly mounted on the upper end of the movable block 8, and the clamping plate 10 corresponds to the position of the hemodialysis catheter 6;

[0036] In this example, when using the catheter protection patch, after the hemodialysis catheter 6 is placed inside the shell 3, the knob at the front end of the knob bidirectional threaded rod 7 can drive the knob bidirectional threaded rod 7 to rotate inside the shell 3. When the knob bidirectional threaded rod 7 rotates, the movable block 8 threadedly connected on its surface can move while being limited by the shell 3 under its rotation. The front and rear movable blocks 8 can move inward or outward at the same time due to the opposite arrangement of the surface threads of the knob bidirectional threaded rod 7. As the movable block 8 moves, the rotating rod 9 and the clamping plate 10 at the upper end of the movable block 8 move at the same time. By adjusting the distance between the front and rear clamping plates 10, the hemodialysis catheter 6 can be limited. The clamp 10 is fixed in position, and can prevent the middle end of the hemodialysis catheter 6 from shaking inside the housing 3 when the hemodialysis catheter 6 is used, thereby avoiding discomfort to the patient. At the same time, the hemodialysis catheter 6 can be clamped, thereby improving the stability of the device. When the hemodialysis catheter 6 is clamped, the rotating rod 9 at the bottom of the clamp 10 is rotatably connected to the movable block 8, and a torsion spring 11 is provided between the clamp 10 and the movable block 8, so that the clamp 10 can be squeezed and rotated when clamped, and the angle can be automatically adjusted. The angle of the clamp 10 can be adaptively adjusted to a suitable angle to clamp the hemodialysis catheter 6, thereby preventing the hemodialysis catheter 6 from deviating. At the same time, it can also be suitable for clamping different hemodialysis catheters 6, and has a wide range of uses.

[0037] Embodiment three:

[0038] like Figure 4 , Figure 6 and Figure 7The technical solution shown in the figure discloses a convenient installation and disassembly mechanism in order to solve the problem of being cumbersome when installing and removing the hemodialysis catheter 6: a clamping block 15 is provided inside the upper front end of the shell 3, and a convenient installation and disassembly mechanism is provided on the outer side of the clamping block 15, and the convenient installation and disassembly mechanism can conveniently engage and install the shell 3 and the cover plate 4 through the clamping block 15, and the convenient installation and disassembly mechanism is provided with a mounting block 12, and the mounting block 12 is fixedly installed at the lower front end of the cover plate 4, and a clamping groove 13 is provided on the outer side of the mounting block 12, and the shell 3 is conveniently engaged with the cover plate 4. A dial plate 14 is provided inside the upper end, and the shape of the dial plate 14 is an "L" shape, and a clamping block 15 is fixedly installed on the inner side of the dial plate 14, and a return spring 16 is fixedly installed on the outer side of the clamping block 15, and the return spring 16 is nested and installed on the inner side of the dial plate 14, and the outer side of the return spring 16 is fixedly installed on the housing 3, the shapes of the clamping block 15 and the clamping slot 13 are both inclined, and the clamping block 15 forms an elastic structure with the housing 3 through the return spring 16, and the clamping block 15 forms a clamping structure with the mounting block 12 through the clamping slot 13;

[0039] When the cover 4 needs to be opened and the hemodialysis catheter 6 needs to be taken out, the setting of the card block 15 and the card slot 13 allows the mounting block 12 to be embedded in the upper end of the shell 3 when the cover 4 needs to be closed. When the mounting block 12 is embedded in the shell 3, due to the inclined shape of the card block 15 itself, when it contacts the mounting block 12, it is squeezed outward to squeeze the return spring 16 until the position of the card block 15 corresponds to the position of the card slot 13. At this time, the card block 15 is automatically engaged in the card slot 13 by the elastic force of the return spring 16 to engage the cover 4 with the shell 3. When the cover 4 needs to be opened and the hemodialysis catheter 6 needs to be taken out, the card block 15 can be pulled out of the engagement of the card slot 13 by toggling the dial plate 14. When the dial plate 14 moves along the inside of the shell 3, the card block 15 is pulled out of the engagement of the card slot 13. At this time, the cover 4 can be directly lifted upward without pressing the patient's skin for leverage, which can avoid patient discomfort and improve the convenience of use for medical staff.
