Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art. It should be understood that the embodiments described below are only some embodiments of the invention, and not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step, without departing from the spirit and scope of the present invention as defined and defined by the appended claims, fall within the scope of protection of the invention.

As shown in fig. 1 to 3, the hemodialysis tube fixing device includes a fixing base 4, a fixing cover plate 6 and two first connecting rods 14, wherein a first threaded hole 11 and a first semicircular groove 10 are formed on a first plane of the fixing base 4, a first through hole and a second semicircular groove 7 matched with the first semicircular groove 10 are formed on a second plane of the fixing cover plate 6, and the fixing cover plate 6 and the fixing base 4 are detachably connected through a bolt 9 matched with the first through hole and the first threaded hole 11.

As shown in fig. 1, two first arc-shaped grooves 16 parallel to each other are formed on a second surface of the fixed base 4 opposite to the first plane, and an L-shaped second connecting rod 3 extending out of the fixed base 4 is provided; two first connecting rods 14 run through a guiding hole that is seted up on one side that fixed baseplate 4 was kept away from to second connecting rod 3 respectively, and the one end that fixed baseplate 4 was kept away from to two first connecting rods 14 is passed through handle portion 1 and is connected, and two first connecting rods 14 are close to one side of fixed baseplate 4 and are connected through kicking block 19, and two and first arc recess 16 complex second arc recess 15 one by one are seted up to the one side that kicking block 19 is close to fixed baseplate 4.

As shown in fig. 1, the flexible layer 8 is disposed on each of the first semicircular groove 10, the second semicircular groove 7, the first arc-shaped groove 16, and the second arc-shaped groove 15.

The bed body of present hospital generally includes the frame body, places the mattress on the frame body and installs the guardrail on the frame body, and the long limit edge of frame body is rectangular tube 5 usually, and the guardrail is assembled by many circular tubes 17 usually.

Regarding the fixation of the hemodialysis tube fixing device to the bed body, as shown in fig. 2, the fixation of the hemodialysis tube fixing device to the bed body can be realized by the cooperation of the first plane, the second plane and the rectangular tube 5. As shown in 3, the fixing of the hemodialysis pipeline fixing device and the bed body can also be realized by the matching of the first semicircular groove 10 and the second semicircular groove 7.

The rectangular tube 5 may have an end portion between the first semicircular groove 10 and the second semicircular groove 7, an intermediate portion between the first semicircular groove 10 and the second semicircular groove 7, or no portion between the first semicircular groove 10 and the second semicircular groove 7, as shown in fig. 1. The flexible layer 8 on the first semicircular groove 10 and the second semicircular groove 7 increases friction force, thereby improving fixing stability.

When the device is used, the handle part 1 is moved in the direction away from the fixed base 4 (the handle part 1 drives the first connecting rod 14 and the top block 19 to move synchronously) and is kept, and then the two pipelines 12 are respectively placed into the two first arc-shaped grooves 16. Then, the external force applied to the handle portion 1 is removed, and under the action of the spring 13, the ejector block 19 moves towards the fixing base 4 (the ejector block 19 drives the first connecting rod 14 and the handle portion 1 to move synchronously) until the flexible layer 8 on the second arc-shaped groove 15 contacts and abuts against the pipeline 12, so that the fixing of the two pipelines 12 is realized under the combined action of the first arc-shaped groove 16 and the second arc-shaped groove 15. The arrangement of the flexible layer 8 on the first arc-shaped groove 16 and the second arc-shaped groove 15 increases friction force, improves fixing stability, and reduces damage to the pipeline 12.

During implementation, for further improving the stability of fixing between hemodialysis pipeline fixing device and the bed body, first through-hole, first screw hole 11 and bolt 9 are two, and the line between 11 centers of two first screw holes is parallel with the length direction of first semicircular groove 10. Meanwhile, in order to facilitate the disassembly and assembly of the fixed base 4 and the fixed cover plate 6, the bolts 9 are butterfly bolts 9.

As shown in fig. 1, the length of the first arc-shaped groove 16 is greater than or equal to the length of the second arc-shaped groove 15, a limiting seat (two protrusions 18 are symmetrical relative to the vertical plane in the first arc-shaped groove 16) matched with the first arc-shaped groove 16 is arranged on the side surface of the fixing base 4 close to the end portions of the first arc-shaped groove 16 (two protrusions), and the limiting seat comprises two protrusions 18 extending to the upper side of the second surface. The clearance between two bulges 18 in the same limiting seat is matched with the outer diameter of the pipeline 12 (can be equal), so that the possibility that the pipeline 12 is separated from the first arc-shaped groove 16 under the action of accidental external force in the period before the pipeline 12 is placed in the first arc-shaped groove 16 and is contacted with the flexible layer 8 on the second arc-shaped groove 15 and abutted against the pipeline 12 is greatly reduced.

Because the length of the first arc-shaped groove 16 is greater than or equal to the length of the second arc-shaped groove 15 (that is, the length of the fixing base is greater than or equal to the length of the fixing block), and the protrusion 18 is located on the side surface of the fixing base 4, the arrangement of the protrusion 18 does not affect the clamping of the first arc-shaped groove 16 and the second arc-shaped groove 15 with the fixing pipeline 12.

As shown in fig. 1, the first link 14 is a screw (a guide hole is not a threaded hole), a nut 2 engaged with the screw is provided on the first link 14 between the handle portion 1 and the second link 3, and the first arc-shaped groove 16 and the second arc-shaped groove 15 are non-semicircular grooves. The relative distance between the nut 2 and the handle part 1 is adjusted by rotating the nut 2, so that the distance between the jacking block 19 and the fixed base 4 (namely the distance between the first arc-shaped groove 16 and the second arc-shaped groove 15) under the action of the spring 13 in a natural state is changed, and the first arc-shaped groove 16 and the second arc-shaped groove 15 combined with non-semicircular grooves (namely the arc length is less than half of the corresponding circumference) realize the fixation of pipelines 12 with different outer diameters in a certain range.

In addition, the screw rod is provided with a marking part which is matched with one side of the second connecting rod 3 far away from the fixed base 4 and used for prompting medical staff to reasonably adjust the position of the nut 2 according to the diameter of the pipeline 12. At this time, the gap between the two protrusions 18 in the same limiting seat is matched with (can be equal to) the outer diameter of the largest pipeline 12, and when a smaller pipeline 12 is fixed, the limiting seat can also play a role in preventing the pipeline 12 from being separated from the first arc-shaped groove 16 under the action of accidental external force.
