Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a protective sleeve for a hemodialysis venous indwelling catheter. Background Art

[0002] Hemodialysis is a treatment method that utilizes the principle of a semipermeable membrane to remove harmful and redundant metabolic wastes and excess electrolytes from the body through diffusion and convection, thereby purifying the blood and correcting the water, electrolyte and acid-base balance. It is one of the important renal replacement therapies for patients with end-stage renal failure. Internal jugular vein catheterization is one of the safest, most effective and most commonly used temporary blood accesses for hemodialysis, and is the key to maintaining the treatment of hemodialysis patients.

[0003] Workers in this field have found that most fixation methods are to directly fix the catheter to the patient's skin with tape. Due to the long-term use of the tape, the tape surface is prone to warping, which may cause the catheter to fall off and the fixation to be loose. On the other hand, since the tape is adhered to the patient's skin for a long time, it may cause discomfort to the patient. For this reason, a protective cover for a hemodialysis venous indwelling catheter is proposed. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides a protective sleeve for a hemodialysis venous indwelling catheter, which is mainly used to solve the following problems: due to the long-term use of the adhesive tape, the surface of the adhesive tape is easy to warp, which may cause the catheter to fall off and the fixation is not firm. On the other hand, due to the long-term adhesion of the adhesive tape to the patient's skin, it may cause discomfort to the patient, and provides the following technical solutions, which will be described in detail below:

[0020] Embodiment 1:

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, an upper protective plate 1 and a lower protective plate 2 are included, the upper protective plate 1 is hinged to one end of the lower protective plate 2, a connecting rod 3 is fixed to the lower protective plate 2, a fixing mechanism 4 is provided at the other end of the connecting rod 3, and a connecting mechanism 5 for convenient connection and fixing is symmetrically provided on the lower protective plate 2; wherein the fixing mechanism 4 includes a lower sleeve 401 hinged to the other end of the connecting rod 3, an upper sleeve 402 is provided on the lower sleeve 401, and slots 403 for placing catheters are fixed at equal intervals in the lower sleeve 401 and the upper sleeve 402, cylinders 404 are fixed at equal intervals on the upper sleeve 402, and the lower sleeve 401 is provided with a fixing mechanism 404. Circular holes 405 are provided at equal intervals, and the cylinders 404 match the circular holes 405. Mounting mechanisms 9 are provided at both ends of the lower sleeve 401 and the upper sleeve 402. The mounting mechanism 9 includes an upper clamping block 901 fixedly connected to both ends of the upper sleeve 402 and a lower clamping block 902 fixedly connected to both ends of the lower sleeve 401. The upper clamping block 901 matches the lower clamping block 902. The outer walls of the upper clamping block 901 and the lower clamping block 902 are threadedly connected with a cylinder 903. The other ends of the upper clamping block 901 and the lower clamping block 902 are fixed with a clamping plate 904. A clamping head 905 is constructed at one end of the cylinder 903, and the clamping head 905 matches the clamping plate 904.

[0022] Specifically: by arranging the connecting mechanism 5 on the lower protective plate 2, the connection of the catheter can be carried out more conveniently, thereby reducing the inconvenience when connecting the catheter to the fixing mechanism 4; in addition, the fixing mechanism 4 for fixing the feeding tube also makes the catheter more firmly fixed, reducing the risk of the catheter falling off or shifting; the combined design of the upper protective plate 1 and the lower protective plate 2 provides better protection; the protective plate can protect the catheter from infection and trauma, and at the same time provide a soft surface to reduce the patient's discomfort.

[0023] The working principle here is: when the catheter needs to be protected, first unscrew the cylinder 903 that is threadedly connected to the outer wall of the upper clamping block 901 and the lower clamping block 902, then place the catheter into the clamping groove 403, and then insert the cylinders 404 fixed with equal intervals on the upper sleeve 402 into the circular holes 405 opened with equal intervals on the lower sleeve 401. Due to the matching circular holes 405 and cylinders 404, the catheter can be clamped between the upper sleeve 402 and the lower sleeve 401, thereby achieving a strong fixing effect and reducing the risk of the catheter falling off or shifting; then the clamping plate 904 of the upper clamping block 901 and the lower The clamping plate 904 of the clamping block 902 is parallel, and the cylinder 903 is threadedly inserted between the lower clamping block 902 and the upper clamping block 901, and tightened so that the clamping head 905 of the cylinder 903 contacts the clamping plate 904. The clamping head 905 presses the clamping plate 904 to fix the outer wall of the catheter, which can fix the catheter. Compared with sticking with tape, this fixation is more firm, which not only improves comfort but also avoids the formation of pressure sores. It is simple to operate and provides a soft surface to reduce the patient's discomfort; close the upper protective plate 1, and finally use the connecting mechanism 5 to fix the upper protective plate 1 and the lower protective plate 2 to the patient's neck. It should be noted that the upper protective plate 1 and the lower protective plate 2 are made of materials with good air permeability. The protective cover of this design has very good softness, can provide higher comfort, and reduce the risk of pain and discomfort caused by long-term use.

[0024] like Figure 1 , Figure 2 As shown, in some embodiments, a lock buckle 6 is fixed at the edge of the upper protective plate 1, and a lock head 7 is fixed at the edge of the lower protective plate 2, and the lock buckle 6 matches the lock head 7. The working principle here is: the lock buckle 6 on the upper protective plate 1 is used in conjunction with the lock head 7 on the lower protective plate 2. When opening the upper protective plate 1, first open the lock buckle 6 from the lock head 7, and then the upper protective plate 1 can be opened; when the upper protective plate 1 needs to be closed, first cover the upper protective plate 1, and then fasten the lock head 7 and the lock buckle 6 to close it.

[0025] like Figure 1 , Figure 2 As shown, in some embodiments, a protective cushion 8 is fixedly mounted on the outer wall of the lower protective plate 2. The working principle here is that the protective cushion 8 can also provide higher comfort and reduce the patient's discomfort. The fixation of the catheter usually takes a long time. If there is no protective cushion 8, the hard lower protective plate 2 may directly contact the patient's skin, causing discomfort or even pain.

[0026] Embodiment 2:

[0027] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0028] like Figure 1 , Figure 2 As shown, in some embodiments, the connection mechanism 5 includes a first connection belt 501 and a second connection belt 502 fixed to the side of the lower protective plate 2, a Velcro sub-surface 503 is fixed on the first connection belt 501, and a Velcro mother surface 504 is fixed on the second connection belt 502. The working principle here is: when the lower protective plate 2 needs to be fixed to the patient's neck, the first connection belt 501 is pulled out from one side of the lower protective plate 2 and closely fits the skin surface, and at the same time, the second connection belt 502 is pulled out from the other side of the lower protective plate 2 and docked with the first connection belt 501, so that the Velcro sub-surface 503 and the Velcro mother surface 504 fit each other. In this way, a firm connection is formed between the first connection belt 501 and the second connection belt 502 through the adhesion of the Velcro.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
