Technical Field

[0001] The invention relates to the technical field of indwelling catheters, in particular to a protective sleeve for an indwelling venous catheter used in daily care of hemodialysis. Background Art

[0002] In the medical field, hemodialysis is a common treatment method for patients with renal failure or certain poisoning conditions. When performing hemodialysis, it is usually necessary to establish a connection with the dialysis machine through vascular access to facilitate blood circulation and purification. At present, commonly used vascular accesses include arteriovenous fistulas, arteriovenous grafts, and central venous catheters. For some patients who cannot establish arteriovenous fistulas or grafts, central venous catheters have become an indispensable choice. However, central venous catheters face many challenges during use, especially in daily care. For example, catheters are easily affected by external physical factors, such as collisions or friction, which may cause catheter damage or even fall off, thereby affecting the dialysis effect and increasing the risk of infection. In addition, during the daily life activities of patients between dialysis sessions, the exposed part of the catheter may be accidentally hooked by clothing or other items, increasing the risk of accidental extubation. Therefore, how to effectively protect these exposed venous indwelling catheters, reduce unnecessary medical accidents, and improve patients' comfort and quality of life has become an urgent problem to be solved.

[0003] In existing medical practices, there are some shortcomings in catheter protection devices, which directly affect the treatment effect and quality of life of patients. One of the main problems is that it is difficult to replace the limit ring of the existing device according to the needs of the patient, resulting in the device as a whole being not firm during use, causing the patient to shake during use, resulting in harm to the patient, and it is difficult to fix the catheter during use, resulting in increased discomfort and potential health risks for the patient during daily use. Based on this, the present invention designs a hemodialysis daily care venous indwelling catheter protective cover to solve the above problems. Summary of the invention

[0029] See also Figure 1-8 , the present invention provides a technical solution:

[0030] A protective sleeve for intravenous indwelling catheter for daily care of hemodialysis includes a deformable plate 1, a limiting ring 51, a replacement mechanism and a fixing mechanism. The replacement mechanism includes a through groove 42. The inside of the deformable plate 1 is symmetrically provided with the through grooves 42. The inside of the deformable plate 1 is provided with a first circular groove 41. A movable rod 43 is movably provided inside the through groove 42. A first spring 44 is fixedly installed outside the movable rod 43. The free end of the first spring 44 is installed on the inner wall of the first circular groove 41. The limiting ring 51 can be replaced by using the movable rod 43 and the first spring 44 in coordination.

[0031] The fixing mechanism includes a conduit groove 62, and a first protective plate 21 is symmetrically installed on the outside of the deformable plate 1, wherein a conduit groove 62 is opened inside one of the first protective plates 21, and a plurality of second circular grooves 63 are symmetrically opened inside the first protective plate 21, and a second spring 64 is installed inside each of the second circular grooves 63, and a second fixing rod 65 is installed at the free end of the second spring 64, and an arc groove 651 is opened at the end of each of the second fixing rods 65. The conduit can be fixed by the two-section arc groove 651;

[0032] The limiting ring 51 is arranged inside the first circular groove 41, and the limiting ring 51 is symmetrically provided with limiting grooves 52 used in conjunction with the movable rod 43, and a silicone protective pad 53 is installed inside the limiting ring 51. The silicone protective pad 53 protects the patient's neck, and the second protective plate 22 is symmetrically installed outside the deformable plate 1, and the first Velcro 23 is installed outside the first protective plate 21, and the second Velcro 24 used in conjunction with the first Velcro 23 is opened outside the second protective plate 22. The deformable plate 1 is combined by the cooperation of the first Velcro 23 and the silicone ring 34;

[0033] The first protective plate 21 and the second protective plate 22 on one side of the outer side of the deformable plate 1 have a first connecting cloth 31 on the outside, and a protrusion 35 is installed at the bottom of the first connecting cloth 31. The first connecting cloth 31 and the protrusion 35 have a fixing groove 36 inside. The second connecting cloth 32 is installed on the outside of the first protective plate 21 and the second protective plate 22 on the other side of the deformable plate 1. The first fixing rod 33 is installed on one side of the outer side of the second connecting cloth 32. The first fixing rod 33 is installed on the outside of the silicone ring 34 used in conjunction with the fixing groove 36. The first protective plate 21 on the side of the second connecting cloth 32 has a square groove 61 on the inside, and a placement plate 66 is installed inside the square groove 61. An elastic sleeve 67 is installed outside the placement plate 66, and a hollow groove 68 is opened inside the elastic sleeve 67. The connector of the front section of the catheter is placed above the placement plate 66, and is fixed by the elastic sleeve 67 at this time. When the syringe needs to be used, it can be quickly used through the hollow groove 68.

[0034] When the patient needs to use the device to protect the catheter, the limiting ring 51 needs to be replaced according to the thickness of the patient's neck, and a suitable limiting ring 51 is placed inside the first circular groove 41. At this time, the limiting groove 52 is aligned with the movable rod 43 and pressed. The movable rod 43 rises under pressure, and the limiting ring 51 enters the limiting groove 52.

[0035] After the limiting ring 51 is fixed, the catheter needs to be fixed and placed inside the catheter groove 62. At this time, one end of the catheter needs to be folded inside the catheter groove 62 to leave a length for the catheter to be driven during the rotation of the patient's neck. After the placement is completed, the catheter needs to be fixed and the catheter is pressed. The second fixing rod 65 is subjected to pressure. At this time, the second spring 64 is compressed to make the second fixing rod 65 enter the second circular groove 63. When the catheter is pressed between the two arc grooves 651, the pressure on the catheter is released. At this time, the second fixing rod 65 is reset by the elastic force of the second circular groove 63, and the catheter is fixed by the two arc grooves 651 to prevent the patient from shaking the catheter during the movement, which may cause harm to the patient. The reserved length of the catheter can ensure that the fixed catheter will not be pulled during the patient's daily rotation of the neck.

[0036] The connector of the front section of the catheter is placed above the placement plate 66 and is fixed by an elastic sleeve 67. When a syringe is needed, it can be quickly used through the hollow groove 68.

[0037] After the catheter is fixed, the device needs to be fixed on the patient. The silicone ring 34 is pressed into the inside of a suitable fixing groove 36 according to the patient's body shape. At this time, the device can be fixed on the patient through the coordinated use of the silicone ring 34 and the fixing groove 36.
