DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0017] In the prior art, after the catheter is led out of the body, it is first fixed at the leading-out site by a fixing tape, and then fixed again by an abdominal catheter fixing belt outside the body (hereinafter referred to as the second fixation) to prevent the catheter from moving relative to the body. However, due to the simple structure of the existing abdominal catheter fixing belt, after the second fixation, the catheter and the body will not move relative to each other. In this way, when the body moves, such as bending over, the change in body shape will cause the catheter between the first fixation and the second fixation to be stretched or bent. The stretching deformation will cause the catheter to be pulled out of the body, and the bending deformation will cause the catheter to extend into the body. Both deformations will cause the catheter to shift, affect the wound, and even tear the wound.

[0018] In view of the problems existing in the prior art, an embodiment of the present invention provides a abdominal catheter fixing belt. Figure 1 As shown, the abdominal catheter fixing belt includes a main connecting plate mechanism 1, and a third Velcro 4 and a fourth Velcro 5 respectively connected to opposite ends of the main connecting plate mechanism 1. The main connecting plate mechanism 1 is provided with a secondary connecting plate mechanism 2, and the secondary connecting plate mechanism 2 is provided with a catheter body 3, and the third Velcro 4 and the fourth Velcro 5 can fix the abdominal catheter fixing belt on the body. When working, the setting of the main connecting plate mechanism 1 can make the catheter body 3 move in the axial direction of the catheter body 3 relative to the third Velcro 4 and the fourth Velcro 5, and the setting of the secondary connecting plate mechanism 2 can make the catheter body 3 move in the radial direction of the catheter body 3 relative to the third Velcro 4 and the fourth Velcro 5.

[0019] The setting of the abdominal catheter fixing belt of the present invention can make the catheter body 3 move relative to the abdominal catheter fixing belt when the body bends or twists, thereby ensuring that the catheter body 3 will not shift, thereby avoiding pulling the wound or even tearing the wound.

[0020] In one embodiment, if Figure 2 As shown, the main connecting plate mechanism 1 includes a main supporting assembly 11 fixedly connected to the third Velcro 4 and the fourth Velcro 5. A first moving groove 12 is provided on the upper end surface of the main supporting assembly 11, and a moving plate 13 is arranged in the first moving groove 12. The moving plate 13 can move in the first moving groove 12 along the axial direction of the catheter body 3. The setting of this example can enable the catheter body 3 to move axially relative to the main supporting assembly 11 in the catheter body 3, and the main supporting assembly 11 is fixed to the body through the third Velcro 4 and the fourth Velcro 5. A first guide support assembly 14 is fixedly connected to the side wall of the moving plate 13, and the free end of the first guide support assembly 14 is fixedly connected to the side wall of the first moving groove 12. The setting of this embodiment, when working, can enable the catheter body 3 to move axially relative to the abdominal catheter fixing belt along the catheter body 3 when the human body moves.

[0021] In one embodiment, if Figure 3 As shown, the setting of the first guide support assembly 14 can not only play a guiding and limiting role for the movement of the movable plate 13, so that the movable plate 13 only moves in the circumferential direction of the catheter body 3, but also provide a reset force for the reset movement of the movable plate 13. In an example, the first guide support assembly 14 includes a first guide support rod 141, a first guide support cylinder 142 and a first guide support spring 143, the first guide support rod 141 is movably inserted in the first guide support cylinder 142, the first guide support spring 143 is wound and arranged outside the first guide support rod 141, and the two ends of the first guide support spring 143 are respectively fixedly connected to the side wall of the first guide support rod 141 and the outer side wall of the first guide support cylinder 142, the first guide support rod 141 is interconnected with the first moving groove 12, and the first guide support cylinder 142 is interconnected with the movable plate 13.

[0022] In order to achieve the effect that the catheter body 3 can rotate relative to the body, in one embodiment, as Figure 5 As shown, the main supporting assembly 11 includes a first supporting plate 111 and a second supporting plate 112, the second supporting plate 112 is arranged above the first supporting plate 111, and a sliding groove 113 is opened on the upper end surface of the second supporting plate 112, and the groove cavity of the sliding groove 113 is an annular structure, and the sliding groove 113 has a first side wall 1131 and a second side wall 1132 opposite to each other, and a plurality of sliding column assemblies 114 are movably arranged in the sliding groove 113, and the plurality of sliding column assemblies 114 are fixedly arranged on the lower end surface of the first supporting plate 111, and the second supporting plate 112 is connected to the first guide support assembly 14.

[0023] During operation, in one example, when the body bends sideways, since the first support plate 111 can rotate relative to the second support plate 112, the catheter body 3 will also rotate relative to the second support plate 112 through the first support plate 111, that is, rotate relative to the body, thereby preventing the catheter body 3 from shifting.

[0024] In order to reduce the friction force when the first supporting plate 111 rotates relative to the second supporting plate 112, in one embodiment, as Figure 6 As shown, the sliding column assembly 114 includes a first sliding column 1141 fixedly connected to the first supporting plate 111, a second sliding column 1143 fixedly connected to the lower end of the first sliding column 1141, a rotating shaft 1142 fixedly sleeved outside the second sliding column 1143, the rotating shaft 1142 and the second side wall 1132 are mutually abuttingly arranged, the lower ends of the rotating shaft 1142 and the second sliding column 1143 are both separated from the bottom wall of the sliding groove 113, and there is a gap 1144 between the rotating shaft 1142 and the first side wall 1131. The setting of this example can change the sliding connection between the rotating shaft 1142 and the first side wall 1131 into a rolling connection, thereby changing the sliding friction into rolling friction, and thus greatly reducing the friction force.

[0025] In an example not shown in the figure, the groove cavity of the sliding groove 113 is a T-shaped structure, the transverse section of the sliding groove 113 is arranged below the vertical section, the diameter of the rotating shaft 1142 is larger than the diameters of the first sliding column 1141 and the second sliding column 1143, the rotating shaft 1142 is arranged in the transverse section of the sliding groove 113, and the first sliding column 1141 is arranged in the vertical section of the sliding groove 113. The purpose of this arrangement is to prevent the sliding column assembly 114 from falling off from the sliding groove 113.

[0026] After the second supporting plate 112 rotates relative to the first supporting plate 111, in order to enable the second supporting plate 112 to achieve the function of automatic reset, in one embodiment, Figure 7As shown, the abdominal catheter fixing belt also includes a reset mechanism 6, which is used to support and limit the movement of the rotating shaft 1142, and drive the rotating shaft 1142 to perform reset movement, that is, drive the second support plate 112 to achieve the effect of automatic reset. In one example, the reset mechanism 6 is arranged in the transverse section of the sliding groove 113. The reset mechanism 6 includes a reset cover body 61 that is movably sleeved outside the rotating shaft 1142, and the reset cover body 61 is movably arranged in the sliding groove 113. The reset cover body 61 is provided with an opening 62, and the opening 62 is arranged toward the second side wall 1132. The purpose of such arrangement is to prevent the reset cover body 61 from contacting the sliding groove 113. A third guide support assembly 63 is fixedly connected to the outer side wall of the reset cover body 61, and the free end of the third guide support assembly 63 is fixedly connected to the baffle 64, and the baffle 64 is fixedly arranged in the sliding groove 113.

[0027] In one embodiment, if Figure 7 As shown, the third guide support assembly 63 includes a third guide support rod 631, a third guide support tube 632 and a third guide support spring 633. The third guide support rod 631 is movably inserted in the third guide support tube 632, and the third guide support spring 633 is wound outside the third guide support rod 631. The two ends of the third guide support spring 633 are respectively fixedly connected to the side wall of the third guide support rod 631 and the outer side wall of the third guide support tube 632. The third guide support rod 631 is interconnected with the reset cover body 61, and the third guide support tube 632 is interconnected with the baffle 64.

[0028] During operation, the movement of the rotating shaft 1142 will move the third guide support rod 631 into or out of the third guide support tube 632 through the reset cover 61. During the movement of the third guide support rod 631, the third guide support spring 633 will be compressed or stretched. When the body is reset, due to the action of the third guide support spring 633, the rotating shaft 1142 will be reset through the reset cover 61, thereby achieving the effect of automatic reset of the second support plate 112 through the sliding column assembly 114.

[0029] In order to enable the catheter body 3 to move in the radial direction of the catheter body 3 relative to the body. Figure 2As shown, the slave connecting plate mechanism 2 includes a second moving groove 21, which is provided on the upper end surface of the moving plate 13, and a slave supporting assembly 22 is provided in the second moving groove 21, and the slave supporting assembly 22 is provided in the second moving groove 21 along the radial movement of the catheter body 3. The setting of the slave supporting assembly 22 enables the catheter body 3 to move in the radial direction of the catheter body 3 relative to the human body. The side wall of the slave supporting assembly 22 is fixedly connected with a second guide support assembly 23, and the free end of the second guide support assembly 23 is fixedly connected to the side wall of the second moving groove 21. The setting of the second guide support assembly 23 plays a limiting role, so that the slave supporting assembly 22 can only move in the radial direction of the catheter body 3. A fixing belt 26 is fixedly connected to the upper end surface of the slave supporting component 22, and the fixing belt 26 is covered outside the catheter body 3. The free end of the fixing belt 26 is fixedly connected to the first Velcro 24, and the lower end surface of the first Velcro 24 is fitted with a second Velcro 25, and the second Velcro 25 is fixedly set on the upper end surface of the slave supporting component 22. During operation, after the abdominal catheter fixing belt is fixed to the body, the fixing belt 26 is pulled open, and the catheter body 3 is placed under the fixing belt 26, and then the fixing belt 26 is reset, and the first Velcro 24 and the second Velcro 25 are fitted together, so that the catheter body 3 is fixed to the abdominal catheter fixing belt.

[0030] In one embodiment, if Figure 4 As shown, the second guide support assembly 23 includes a second guide support rod 231, a second guide support tube 232 and a second guide support spring 233. The second guide support rod 231 is movably inserted in the second guide support tube 232, and the second guide support spring 233 is wound and arranged outside the second guide support rod 231.

The swing mechanism 7 includes a fixing seat 71 fixedly disposed on the upper end surface of the fourth support plate 222, and in one example, the fixing seat 71 is fixed to the middle of the fourth support plate 222. The fixing seat 71 is provided with a swinging groove 72, in which a swinging ball 73 is movably arranged, and a connecting rod 74 is fixedly connected to the upper end surface of the swinging ball 73. The swinging ball 73 leads the connecting rod 74 to swing in multiple directions in the swinging groove 72, so that the third supporting plate 221 can swing in multiple directions relative to the fourth supporting plate 222 through the connecting rod 74, and then the catheter body 3 can swing in multiple directions relative to the body through the third supporting plate 221, so that the abdominal catheter fixing belt has a wider range of applications. The connecting rod 74 is fixedly connected to the lower end surface of the third supporting plate 221, and preferably, the connecting rod 74 is fixed to the middle part of the third supporting plate 221. A plurality of connecting springs 75 are fixedly connected to the lower end surface of the third supporting plate 221, and the lower ends of the connecting springs 75 are fixedly connected to the upper end surface of the fourth supporting plate 222. The setting of the connecting springs 75 can be used to connect the third supporting plate 221 and the fourth supporting plate 222, and can also drive the third supporting plate 221 to automatically reset relative to the fourth supporting plate 222 after the third supporting plate 221 swings relative to the fourth supporting plate 222; specifically, in one example, when the third supporting plate 221 swings to the left, the connecting spring 75 on the left is compressed, and when the body returns to normal, the connecting spring 75 on the left will push the third supporting plate 221 to reset, and the working principles in other directions are the same and will not be repeated here.
