Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an open hemodialysis catheter fixing belt. Background Art

[0002] In the prior art, hemostatic clamps are usually used to fix the hemodialysis catheter during hemodialysis. However, the following disadvantages exist when hemostatic clamps are used to fix the pipeline: 1. Since hemostatic clamps are shared instruments, they must be disinfected after use by each patient in the hemodialysis room. If the disinfection is not thorough, there will be cross-infection problems; 2. The hemostatic clamps are easy to injure the patient during use; 3. There is a risk of the hemostatic clamps falling when hung on the infusion stand of the dialysis machine, which may easily injure the patient after falling. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems and provide an open hemodialysis catheter fixing belt. To achieve the above purpose, the utility model adopts the following technical solutions:

[0004] An open hemodialysis catheter fixing belt comprises a belt body, two ends of the belt body are provided with Velcro strips that cooperate with each other, a catheter fixing piece is provided in the middle of the belt body, and the catheter fixing piece is bonded or snap-fitted to the belt body;

[0005] The catheter fixing piece is provided with a groove for clamping the catheter, and a protrusion is provided on the top of the groove. The protrusion leaves only a narrow gap at the top of the groove through which the catheter can pass after deformation.

[0006] As an improvement, the belt body is further provided with an auxiliary fixing belt, which is arranged perpendicular to the belt body and fixedly connected to the belt body at the tail, and a clip is provided at the end of the auxiliary fixing belt.

[0007] As an improvement, the number of the catheter fixing members is two, and each of the catheter fixing members is provided with two to three grooves.

[0008] As an improvement, the number of the auxiliary fixing belts is 1-2.

[0009] As an improvement, the belt body is made of elastic material.

[0010] The advantages of the utility model are:

[0011] 1. When the utility model is used, the belt body is directly fixed around the upper arm horizontally, and then the hemodialysis catheter is clamped inside the groove; it has the advantages of good fixing effect and convenient use.

[0012] 2. The utility model has low production cost and can be used by one person only, thus avoiding the risk of cross infection caused by the sharing of hemodialysis catheter fixing devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0021] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
