Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis auxiliary facilities and equipment, and particularly relates to a fixing and protecting component for hemodialysis tubes used in hemodialysis. Background Art

[0002] In the current method, patients generally lie in bed during hemodialysis, and then hemodialysis tubes are inserted. Generally, one end of the hemodialysis tube is used as the main tube, that is, the insertion end, and the other end is a double-branch tube, making the whole in a Y shape; one end of the double-branch tube drains venous blood, and one end is connected to a dialysis pump for reflux. The problem in the prior art is that there is almost no support and auxiliary fixation for the part of the dialysis tube between the proximal end of the patient and the distal end on the side of the dialysis pump. The common method is that the dialysis equipment is almost at the same height as the hospital bed, and the hemodialysis tube is fixed by medical adhesive stickers. Obviously, small adjustment movements or sudden movements of the patient are extremely likely to cause the stickers to fall off, and even more potential hidden danger situations.

[0040] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. It should be noted that, for the convenience of description in this application, the "left side" in the current view is the "first end", the "right side" is the "second end", the "upper side" is the "first end", and the "lower side" is the "second end". The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0041] The present utility model aims to solve the technical problem of the lack of an active protection component for hemodialysis tubes used in hemodialysis in the prior art, and provides a fixing and protecting component for hemodialysis tubes used in hemodialysis. First of all, it should be noted that: hemodialysis tubes are not suitable for the clamping method because in the current method and in clinical practice, due to too slow blood flow rate, coagulation problems will occur and need to be disposed of immediately. Therefore, this technical solution does not adopt the clamping method, but uses a support-based method. Specifically: Please refer to Figure 1 As shown, this technical solution can be placed on a medical table or a medical rack on one side of the hospital bed. The inlet end involved in this application is the side close to the patient, and the distal end is the opposite. First is the first fixed support assembly 10. The proximal end of the main tube 1 of the hemodialysis tube can be inserted into a first fixing hole 10a, and the main tube 1 can be supported by a first U-shaped support structure 10u; as shown in the attached Figure 2 、 3 As shown, that is, a part is inserted into the first fixing hole 10a for limiting, and the other part is supported by the first U-shaped support structure 10u, that is, it is not a double-insertion type. The purpose is to facilitate connection and fixation. Similarly, the same method is adopted for the arterial and venous branch tubes, that is:

[0042] Two groups of second fixed support assemblies 20. The two branch tubes 2 of the hemodialysis tube can be respectively arranged on a group of second fixed support assemblies 20; one end of the branch tube 2 can be supported by a second U-shaped structure support 20u and can penetrate into a second fixing hole 20a;

[0043] The above is the same as the fixing method of the main tube 1. In order to facilitate connection, the second U-shaped structure support 20u is configured at the distal end;

[0044] When viewed in a top-down direction, the first fixed support assembly 10 and the two groups of second fixed support assemblies 20 are arranged in a triangular shape, and the first fixed support assembly 10 and the second fixed support assembly 20 are connected to a support group 30 so that they are all in the same plane;

[0045] Through the above solution, the advantages are:

[0046] (1) It can effectively limit and protect the hemodialysis tube, and has a simple structure and convenient connection;

[0047] (2) This technical solution will not cause clamping - type limitation to the hemodialysis tube, and can also effectively prevent unnecessary displacement of the hemodialysis tube caused by the actions of patients.

[0048] In Embodiment 1, the two groups of second fixed support components 20 are arranged in the same row.

[0049] In Embodiment 2, the two groups of second fixed support components 20 are arranged staggeredly.

[0050] In both embodiments, this arrangement method can adapt to the actual models of different hemodialysis tubes, making the applicable range wider.

[0051] In a specific configuration, the first fixing hole 10a is larger than the diameter of the main pipe 1, and the second fixing hole 20a is larger than the diameter of the branch pipe 2.

[0052] In a specific embodiment, as shown in the appendix Figures 1-3 The first fixed support component 10 includes: two groups of first arrangement blocks 101, and a plurality of connecting rods 101b are arranged between the two groups of first arrangement blocks 101 and are vertically connected to the lower ends of the first arrangement blocks 101, so that the two groups of first arrangement blocks 101 are kept parallel; the plurality of connecting rods 101b play a role in maintaining strength, reduce the weight of the overall configuration, and can also play an auxiliary supporting role for the main pipe 1 when tube displacement occurs. Moreover, there is a space between the connecting rods 101b, which will not cause extrusion of the main pipe 1 to result in flow restriction.

[0053] Among them, the proximal first arrangement block 101 is provided with a first U - shaped support structure 10u, and the first U - shaped support structure 10u is a U - shaped notch;

[0054] Among them, a first fixing hole 10a concentric with the first U - shaped support structure 10u is opened on the distal first arrangement block 101.

[0055] In a specific embodiment, as shown in the appendix Figures 1-3 The purpose of the following configuration is the same as above. Specifically, each group of second fixed support components 20 includes:

[0056] Two groups of second arrangement blocks 201, and a plurality of secondary connecting rods 201b are arranged between the two groups of first arrangement blocks 101 and are vertically connected to the lower ends of the second arrangement blocks 201, so that the two groups of second arrangement blocks 201 are kept parallel;

[0057] Among them, the distal second arrangement block 201 is provided with a second U - shaped support structure 20u, and the second U - shaped support structure 20u is a U - shaped notch;

[0058] Among them, a second fixing hole 20a concentric with the second U-shaped support structure 20u is formed in the proximal second arrangement block 201.

[0059] In addition, for the support formed by the support group 30, please refer to the appendix Figure 2 、 3 As shown, support columns 301 are arranged below the first arrangement block 101 and the second arrangement block 201, and the support columns 301 are connected to a support block 302.

[0060] In addition, a transverse connecting rod column 303 can be connected between the support blocks 302 of two adjacent second fixed support assemblies 20;

[0061] Including that the support block 302 of a group of second fixed support assemblies 20 and the support block 302 of the first fixed support assembly 10 are connected by a longitudinal connecting rod column 304;

[0062] In this way, the first fixed support assembly 10 and the two groups of second fixed support assemblies 20 form a triangular configuration in the top view direction, that is, it is more stable when in use.

[0063] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
