DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-4 A hemodialysis central venous catheter fixing and protecting device comprises a placement plate 1, both ends of the placement plate 1 are fixedly connected with binding belts 2, both ends of the top of the placement plate 1 are fixedly connected with limiting plates 3, tightening belts 4 are arranged inside the two limiting plates 3, and the tightening belts 4 are adhesively connected to the binding belts 2, a deformation plate 5 is fixedly connected between the two tightening belts 4, and a locking assembly 8 is arranged between the bottom ends of the two binding belts 2, and the locking assembly 8 is used to cooperate with the binding belts 2 to position the placement plate 1;

[0024] In detail, the deformation plate 5 is arched, and a sponge protective pad is fixedly connected to the inner side of the deformation plate 5. By utilizing the shape characteristics of the deformation plate 5, when the tightening belt 4 is pulled, the deformation plate 5 will be deformed until the deformation plate 5 contacts the intravenous catheter;

[0025] The bottom end of the tightening belt 4 is fixedly connected with a Velcro A surface 6, and the outer side of the binding belt 2 is fixedly connected with a Velcro B surface 7, and the Velcro A surface 6 and the Velcro B surface 7 are bonded and connected. The structural cooperation of the Velcro A surface 6 and the Velcro B surface 7 enables the tightening belt 4 and the binding belt 2 to be stably connected, and the tightening belt 4 and the binding belt 2 can be separated conveniently;

[0026] It can be understood that between the placement plate 1 and the deformation plate 5, the tightening belt 4 is then pulled to cause the deformation plate 5 to deform until the deformation plate 5 contacts the intravenous catheter. At the same time, the tightening belt 4 is bonded to the Velcro B surface 7 through the Velcro A surface 6 to lock the position of the tightening belt 4, so as to position the intravenous catheter between the placement plate 1 and the deformation plate 5 and protect the intravenous catheter.

[0027] Embodiment 2:

[0028] See also Figure 1-4, this embodiment provides a technical solution based on the first embodiment: the locking assembly 8 includes a carrying box 9, a limiting hole 10, a limiting seat 11 and a linear slide bar 12, both ends of the carrying box 9 are provided with limiting holes 10, and the two binding belts 2 are respectively assembled in the two limiting holes 10, both ends of the inside of the carrying box 9 are fixedly connected to the limiting seat 11, the middle part of the limiting seat 11 is laterally slidably connected with the linear slide bar 12, the ends of the two linear slide bars 12 away from each other are fixedly connected with the positioning plate 13, the end of the linear slide bar 12 away from the positioning plate 13 is fixedly connected with the limiting piece 14, a coil spring 15 is fixedly connected between the limiting piece 14 and the limiting seat 11, a transmission rod 17 is slidably connected to the middle part of one side of the carrying box 9, and the end of the transmission rod 17 located inside the carrying box 9 is fixedly connected with a transmission frame 18, and the two ends of the transmission frame 18 are respectively fitted with the two pressure inclined plates 16;

[0029] In summary, the transmission rod 17 is pushed to cause the transmission frame 18 to move linearly, and the transmission frame 18 is connected with the pressure inclined plate 16, so that the pressure inclined plate 16 is pressed to drive the positioning plate 13 away from the limiting hole 10 under the limit of the linear slide rod 12, thereby unlocking the binding belt 2, and then pushing the carrying box 9 to move it at the binding belt 2 until the carrying box 9 contacts the human body;

[0030] Furthermore, one end of the transmission rod 17 located outside the carrying box 9 is fixedly connected to a force-bearing pull block, and the outer side of the force-bearing pull block is fixedly connected to a protective cover. By setting the force-bearing pull block, personnel can conveniently apply force to the transmission rod 17;

[0031] Preferably, both ends of the transmission frame 18 are provided with extrusion slopes adapted to the inclined surface of the pressure inclined plate 16, and the extrusion slopes are in contact with the inclined surface of the pressure inclined plate 16. By utilizing the mutual cooperation between the extrusion slopes and the inclined surface of the pressure inclined plate 16, the positioning plate 13 can be driven to perform adaptive position adjustment while the transmission frame 18 is linearly displaced.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When working, first wear the binding belt 2 at the lead-out position of the personnel's intravenous catheter, then push the transmission rod 17 to cause the transmission frame 18 to move linearly, cooperate with the connection between the transmission frame 18 and the pressure inclined plate 16, so that the pressure inclined plate 16 is pressed to drive the positioning plate 13 away from the limiting hole 10 under the limit of the linear slide bar 12, thereby forming the unlocking of the binding belt 2, and then push the carrying box 9 to move it at the binding belt 2 until the carrying box 9 contacts the human body, and at the same time release the force on the transmission rod 17. During the displacement of the positioning plate 13, the coil spring 15 will be stretched by force, and then when the transmission rod 17 loses its pressure, the rebound of the coil spring 15 can be used to cause the positioning plate 13 to be in close contact with the binding belt 2, so as to position the binding belt 2 at the limiting hole 10, and finally form the tightening of the binding belt 2, so as to bind the placement plate 1 to the lead-out position of the personnel's intravenous catheter;

[0034] The intravenous catheter is placed between the placement plate 1 and the deformation plate 5, and then the tightening belt 4 is pulled to cause the deformation plate 5 to deform until the deformation plate 5 contacts the intravenous catheter. At the same time, the tightening belt 4 is bonded to the Velcro B surface 7 through the Velcro A surface 6 to lock the position of the tightening belt 4, so as to position the intravenous catheter between the placement plate 1 and the deformation plate 5 to protect the intravenous catheter. Since the deformation plate 5 is locked by bonding the Velcro A surface 6 to the Velcro B surface 7, before the intravenous catheter is used, it is necessary to first unlock the deformation plate 5 to keep 05 away from the intravenous catheter. When the intravenous catheter is in use, the intravenous catheter can be effectively positioned and protected by the deformation plate 5, which can effectively prevent people from unplanned tube removal.
