[0035] The present application will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] Embodiment 1

[0037] Please refer to Figures 1-11Among them, a dialysis pipeline bed rail fixing clip capable of detecting the recirculation rate of a hemodialysis access provided in this embodiment includes: a lower clip body 1, a top of the lower clip body 1 is rotatably connected to an upper clip body 101, a fixing block 103 is fixedly connected to one side of the lower clip body 1, an installation block 3 is connected to the top of the upper clip body 101, and a device block 6 is provided on the top of the installation block 3; a fixing component disposed between the upper clip body 1 and the lower clip body 1, the fixing component includes: an arc-shaped groove 104, a top-out groove 2, a fastening block 201 and an arc-shaped block 207; a rotating component disposed between the installation block 3 and the device block 6, the rotating component includes: a rotating groove 301, a top plate 4, a sleeve 401, a clamping block 404, a rotating plate 501 and a clamping groove 502; and a monitoring component disposed inside the device block 6, the monitoring component includes: a monitoring device 7, a fixing groove 601, a rotating cover 602 and a clamping block 603.

[0038] Among them, through the setting of the fixing component, bed rails of different sizes can be quickly clamped and fixed, facilitating the fixing of the device block 6 on bed rails of different sizes. And with the setting of the rotating component, the orientation of the device block 6 can be adjusted to make the fixing groove 601 face the direction of the dialysis pipeline, so as to facilitate the subsequent clamping of the dialysis pipeline, and the orientation of the device block 6 is limited while the fixing clip clamps the bed rail. Then, through the setting of the monitoring component, on the one hand, the dialysis pipeline can be fixed to prevent the situation of tube detachment, and on the other hand, the urea nitrogen level in the pipeline can be monitored, and then the recirculation rate can be calculated.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, one end of the upper clip body 101 is connected with a pressing plate 206, two arc-shaped blocks 207 are connected to the bottom of the pressing plate 206, two arc-shaped grooves 104 corresponding to the positions of the arc-shaped blocks 207 are opened on the fixing block 103, a plurality of rubber strips 102 are provided on the inner arc surfaces of the upper clip body 101 and the lower clip body 1, a top-out groove 2 communicated with the arc-shaped groove 104 is opened inside the fixing block 103, a fastening block 201 is provided inside the top-out groove 2, one side of the fastening block 201 is arc-shaped, ratchet teeth are provided on the arc-shaped surface of the fastening block 201 and the outer arc surface of the arc-shaped block 207, a plurality of top-out springs 202 are connected between the fastening block 201 and the top-out groove 2, a through hole 205 is opened on one side of the fixing block 103, one side of the fastening block 201 is connected with a pull rod 203, and one end of the pull rod 203 passes through the through hole 205 and is connected with a pull plate 204.

[0041] When using the fixed clip, pull the pull plate 204, so that the pull plate 204 drives the fastening block 201 to separate from the arc-shaped block 207 through the pull rod 203, thereby separating the upper clip body 101 from the lower clip body 1. Then place the clip body on the bed rail. Next, drive the upper clip body 101 to close towards the lower clip body 1 by pressing the pressing plate 206. At this time, the arc-shaped block 207 is inserted into the arc-shaped groove 104, and the fastening block 201 is pushed open by the ratchet teeth on the outer arc surface of the arc-shaped block 207 until the upper clip body 101 and the lower clip body 1 clamp and fix the bed rail. At this time, the fastening block 201 pops out under the action of the elastic force of the ejecting spring 202, so that the arc surface of the fastening block 201 closely adheres to the arc-shaped block 207. And through the setting of the ratchet teeth, it can prevent the arc-shaped block 207 from retreating, completing the position fixation of the upper clip body 101 and the lower clip body 1. Then, through the setting of multiple rubber strips 102, the clamping and fixing effect on the bed rail can be increased, avoiding the situation of slipping after the fixed clip is clamped and fixed.

[0042] Embodiment Three

[0043] On the basis of Embodiment One and Embodiment Two, further, a rotating groove 301 is opened inside the mounting block 3, a moving groove 302 is opened inside the mounting block 3, a sleeve 401 is slidably connected inside the moving groove 302, the bottom end of the sleeve 401 is fixedly connected to a top plate 4 in an arc structure, a connecting rod 402 is slidably connected to the top of the sleeve 401, a return spring 405 is sleeved outside the connecting rod 402, the top of the connecting rod 402 is fixedly connected to a fixing plate 403, a plurality of clamping blocks 404 are connected to the top of the fixing plate 403, and the plurality of clamping blocks 404 are evenly distributed in a circular array. The bottom of the device block 6 is connected to a rotating block 5, the bottom of the rotating block 5 is connected to a rotating plate 501, and the rotating plate 501 is located in the rotating groove 301. A plurality of card slots 502 are opened at the bottom of the rotating plate 501, and the plurality of card slots 502 are evenly distributed in a circular array. A plurality of rollers 503 are installed at the bottom of the rotating plate 501.

[0044] During the installation process, according to the position of the patient's hemodialysis pipeline, manually rotate the device block 6 so that the rotating cover 602 of the device block 6 faces the dialysis pipeline, and keep the orientation of the device block 6 when the upper clip body 101 and the lower clip body 1 are closed. When the device block 6 rotates, it drives the rotating block 5 and the rotating plate 501 to rotate. And through the setting of the plurality of rollers 503 at the bottom of the rotating plate 501, the device block 6 can rotate smoothly.

[0045] When the upper clamping body 101 and the lower clamping body 1 are closed, the bed rail contacts the top plate 4 and pushes the top plate 4 upward, causing the top plate 4 to drive the sleeve 401 to move upward. At this time, under the action of the elastic force of the return spring 405, the fixing plate 403 and the connecting rod 402 are driven to move upward until the latch 404 contacts the lower surface of the rotating plate 501. At this time, as the upper clamping body 101 and the lower clamping body 1 are fixed, the top plate 4 is squeezed by the bed rail to fit with the upper clamping body 101, causing the return spring 405 to be deformed and accumulate elastic force by the fixing plate 403 and the sleeve 401. After the fixing clamp is fixed, the equipment block 6 can be manually rotated, so that the equipment block 6 drives the rotating plate 501 to rotate, making the card slot 502 on the rotating plate 501 correspond to the position of the latch 404. At this time, the return spring 405 releases the elastic force and springs the latch 404 into the card slot 502 to clamp and fix the rotating plate 501, completing the orientation fixing of the rotating plate 501 and the equipment block 6. Through the setting of multiple card slots 502, the equipment block 6 can adjust the orientation according to the actual use requirements, facilitating the subsequent clamping and monitoring of the dialysis pipeline.

[0046] Embodiment 4

[0047] On the basis of Embodiment 1, two fixing grooves 601 are opened at the top of the equipment block 6. A rotating cover 602 is rotatably connected to the top of the equipment block 6. A plurality of slotted openings 604 are opened on one side of the rotating cover 602 close to the equipment block 6. A clamping spring 605 is connected inside the slotted opening 604. One end of the clamping spring 605 is connected with a clamping block 603. The top of the clamping block 603 is connected with two symmetrically arranged limiting rods 606. The rotating cover 602 is provided with limiting holes 607 that cooperate with the limiting rods 606. A second magnet 609 is connected to the top of the equipment block 6. A first magnet 608 is connected to the bottom of the rotating cover 602. A display screen 701 is installed on one side of the equipment block 6. A monitoring device 7 is installed inside the equipment block 6. A UV light source 702 and a UV detector 703 are respectively installed on the inner wall of the fixing groove 601, and the UV light source 702 and the UV detector 703 are symmetrically arranged.

[0048] When performing blood purification treatment on patients with renal failure and the like, the rotating cover 602 is unscrewed. At this time, the first magnet 608 is separated from the second magnet 609. Then, the dialysis pipeline at the blood drawing end and the dialysis pipeline at the blood return end are respectively placed in the two fixing grooves 601. Then, the rotating cover 602 is closed, so that the first magnet 608 and the second magnet 609 are reattached, and the rotating cover 602 is magnetically adsorbed and fixed.

[0049] At this time, the clamping block 603 contacts the dialysis pipeline and clings to the dialysis pipeline under the action of the elastic force of the clamping spring 605, so that the dialysis pipeline can cling to the inner wall of the fixing groove 601. At the same time, one side of the clamping block 603 is arc-shaped, and the elastic force generated by the clamping spring 605 is not enough to deform the clamped dialysis pipeline. Therefore, the liquid flow inside the dialysis pipeline will not be affected. Through the arrangement of the limiting hole 607 and the limiting rod 606, the moving direction of the clamping block 603 can be limited;

[0050] After the dialysis pipeline is clamped into the fixing groove 601, ultraviolet rays are emitted by the UV light source 702. Although urea itself has no obvious absorption peak in the ultraviolet spectrum, other small molecules in the dialysis fluid or blood (such as creatinine, uric acid, etc.) have ultraviolet absorption characteristics, and creatinine, uric acid, and urea nitrogen are all products of in vivo metabolism and will accumulate in the blood in the case of renal insufficiency. Therefore, during hemodialysis, as these substances are gradually removed, their concentrations will decrease. At this time, the ultraviolet rays passing through the dialysis pipeline are monitored by the UV detector 703, and the monitored data is converted into an electrical signal and sent to the monitoring device 7. By comparing the difference between the intensity of the original light source and the light intensity after passing through the dialysis pipeline, the level of urea nitrogen is calculated. Then, by calculating the levels of urea nitrogen in the dialysis pipeline at the blood-drawing end and the blood-return end, the recirculation rate of the vascular access is calculated, and the above calculation data is displayed through the display screen 701. The recirculation rate (%) = (Cv - Ca) / Cv * 100%, where Cv is the urea nitrogen concentration at the venous end (blood-return end), and Ca is the urea nitrogen concentration at the arterial end (blood-drawing end).

[0051] Among them, the UV light source 702 is a Thorlabs M330L3 UV LED, and the UV detector 703 is a Vishay VEMD5010X01 photodiode.

[0052] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0053] The above has introduced in detail a dialysis pipeline bed rail fixing clip capable of detecting the recirculation rate of a hemodialysis access. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
