DETAILED DESCRIPTION

[0039] The technical solutions in the application will be described in detail below with reference to the drawings in the application. Obviously, the described embodiments are only some of the embodiments of the application, not all the embodiments. The components of the application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0040] It should be noted that: similar numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] As Figures 1-4 shown, a hemodialysis pipeline fixing device convenient to connect, comprising:

[0042] A fixed support 1 is fixed on a support rod 3 (the support rod 3 can be a rod on a bed fence) by a clamping unit 2;

[0043] A main fixed assembly 4 is fixedly connected with the fixed support 1, and a main guide groove unit 41 is formed at the front end of the main fixed assembly 4;

[0044] An auxiliary fixed assembly 5 is arranged in the main fixed assembly 4;

[0045] An auxiliary guide groove unit 51 is formed at the front end of the auxiliary fixed assembly 5, and when the auxiliary fixed assembly 5 moves downward and the front end surface of the main fixed assembly 4 coincides with the front end surface of the auxiliary fixed assembly 5, the main guide groove unit 41 and the auxiliary guide groove unit 51 form a complete guide groove structure in cooperation;

[0046] The main guide groove unit 41 and the auxiliary guide groove unit 51 are used to place the arterial pipeline and the venous pipeline;

[0047] The main guide groove unit 41 and the auxiliary guide groove unit 51 are further provided with a plurality of groups of guide units 6, which are used to clamp the arterial pipeline and the venous pipeline into the interior of the main guide groove unit 41 or the auxiliary guide groove unit 51.

[0048] Among them, the clamping unit 2 refers to a fixed mechanism with adjustable clamping force, which can be realized by an elastic clamping piece with anti-skid lines, and is fixed on a support rod 3 such as a bed fence through mechanical lock or magnetic attraction. The main guide groove unit 41 refers to a guide channel with a specific cross-sectional shape, which can adopt a semicircular groove structure formed by injection molding, and the groove depth can be set to 1 / 2 to 2 / 3 of the pipeline diameter. The auxiliary guide groove unit 51 refers to a complementary extension structure of the main guide groove, the curvature radius of the arc-shaped part 71 matches the main guide groove, ensuring that a continuous guide surface is formed after splicing. The guide unit 6 refers to a limiting component provided on the edge of the guide groove.

[0049] Specifically, the main fixed assembly 4 and the auxiliary fixed assembly 5 realize relative displacement through sliding fit. When it is necessary to extend the pipeline fixing length, the auxiliary fixed assembly 5 can be pulled out from the cavity of the main assembly. At this time, the main guide groove and the auxiliary guide groove form a continuous channel. The guide units 6 are distributed at intervals along the guide groove and have a segmented limiting effect when the pipeline is clamped. When the pipeline is accidentally pulled, the elastic limiting structure of the guide unit 6 allows the pipeline to have a small amount of displacement, avoiding the instantaneous pulling force acting directly on the patient's body.

[0050] Through the above technical scheme, the present application realizes the orderly storage and reliable fixation of the dialysis pipeline. The expandability of the guide groove structure adapts to the pipeline length requirement of different treatment scenes. The multi-point limiting mechanism of the guide unit 6 effectively prevents the pipeline from slipping. When the pipeline is pulled by external force, the elastic limiting structure can buffer the pulling force impact, reducing the discomfort of the patient. The adjustable characteristics of the device enable medical staff to quickly adjust the fixed position according to the actual use, improving the clinical operation efficiency.

[0051] Further, as shown in Figures 1-4 The main guide groove unit 41 and the auxiliary guide groove unit 51 respectively include two groups of guide grooves 7 arranged in parallel, one group of the guide grooves 7 is used to place the arterial pipeline, and the other group of the guide grooves 7 is used to place the venous pipeline.

[0052] Among them, the main guide groove unit 41 refers to the two groups of parallel guide grooves 7 structures opened at the front end of the main fixing component 4, which can be specifically formed on the polymer material by injection molding process. The cross-sectional shape of the groove body matches the outer diameter of the pipeline and is used to constrain the position of the arterial pipeline. The auxiliary guide groove unit 51 refers to the two groups of parallel guide grooves 7 structures opened at the front end of the auxiliary fixing component 5. The depth of the groove body can be set to be slightly larger than the diameter of the pipeline and is used to accommodate the venous pipeline. The parallel layout of the two groups of guide grooves 7 eliminates the possibility of pipeline contact through spatial isolation.

[0053] Specifically, the arterial pipeline is constrained in a group of guide grooves 7 of the main groove unit 41, and the venous pipeline is constrained in another group of guide grooves 7. The axes of the two groups of guide grooves 7 remain parallel, so that the arterial pipeline and the venous pipeline form a straight line arrangement that does not intersect each other after fixation. When the secondary fixing component 5 moves to coincide with the front end face of the main fixing component 4, the guide grooves 7 of the main groove unit 41 and the secondary guide groove unit 51 form a continuous channel. During the movement, the pipeline is always limited by the side wall of the groove body. The groove edge of the guide groove 7 is designed as a rounded transition structure to avoid wear on the pipeline surface.

[0054] Further, if Figures 3-4 As shown, the guide groove 7 includes at least one set of arc-shaped portions 71 and at least one set of straight portions 72, and the arc-shaped portions 71 and the straight portions 72 are integrally formed;

[0055] The arc-shaped portion 71 at the lower end of the main guide groove unit 41 and the arc-shaped portion 71 at the upper end of the auxiliary guide groove unit 51 are spliced ​​with each other.

[0056] Among them, the arc portion 71 refers to a trough structure with a curved contour, which can be specifically realized by an arc-shaped or parabolic surface. The bending radius can adapt to the minimum bending radius requirement of the standard dialysis tube and is used to guide the natural transition of the pipeline. The straight portion 72 refers to a trough body with a straight extension structure, which is used to provide a stable linear support segment. The arc portions 71 are spliced ​​together to form a continuous curvature transition between the arc contours of the main guide groove and the auxiliary guide groove in the closed state.

[0057] Further, if Figures 3-5 As shown, the guide unit 6 is installed between the straight portion 72 for placing the arterial line and the straight portion 72 for placing the venous line, and the front ends of the main fixing component 4 and the auxiliary fixing component 5 are respectively provided with a movable groove 42 at a position corresponding to the guide unit 6;

[0058] The guide unit 6 includes a movable part 61 clamped inside the movable groove 42, a connecting part 62 fixedly connected to the movable part 61, a first guide part 63 fixedly connected to one end of the connecting part 62 and resting on the upper end of the straight part 72 for placing the arterial line, and a second guide part 64 fixedly connected to the other end of the connecting part 62 and resting on the upper end of the straight part 72 for placing the venous line.

[0059] Among them, the guide unit 6 refers to a component used to guide the arterial line and the venous line to be placed inside the guide groove structure. It can be specifically implemented by a movable part 61 with a connecting part 62 and two guide parts. The position adjustment is achieved by the displacement of the movable part 61 in the movable groove 42. The movable groove 42 refers to a long strip groove opened on the front end surface of the main and auxiliary fixed components 5. It can be specifically implemented by a slide rail structure that matches the shape of the movable part 61 of the guide unit 6, providing lateral movement space for the guide unit 6.

[0060] Specifically, the guide unit 6 is embedded in the movable groove 42 through the movable part 61 to achieve lateral sliding. When the position of the pipeline needs to be adjusted, the operator can push the guide unit 6 to move horizontally along the movable groove 42, so that the first guide part 63 and the second guide part 64 respectively cover the straight parts 72 of the arterial pipeline and the venous pipeline. During the movement, the connecting part 62 of the guide unit 6 is always located between the two straight parts 72, ensuring that the two pipelines maintain a parallel interval to avoid cross-entanglement. The movable groove 42 opened at the front end of the main and auxiliary fixed components 5 corresponds to the position of the guide unit 6, so that the guide unit 6 is always in the middle area of ​​the two straight parts 72 during the adjustment process, maintaining a symmetrical guiding effect on the pipeline.

[0061] Further, if Figures 6-7 As shown, a sliding groove 43 is respectively provided on both sides of the main fixing component 4, and the sliding groove 43 is L-shaped. The lower ends of both sides of the main fixing component 4 are also provided with an integrally formed convex plate 44, and the horizontal section of the L-shaped sliding groove 43 is provided on the convex plate 44;

[0062] Sliding blocks 52 are fixedly provided on both sides of the auxiliary fixing component 5 at positions corresponding to the sliding slots 43 , and the sliding blocks 52 are clamped inside the sliding slots 43 .

[0063] The L-shaped sliding groove 43 refers to a guide rail structure with a vertical section and a horizontal section connected, the vertical section limits the left and right deviation of the sliding block 52 when moving up and down, and the horizontal section is supported transversely by the protruding plate 44. The protruding plate 44 refers to a plate-shaped structure extending downward from the side wall of the main fixed assembly 4, which can be integrally formed with the main fixed assembly 4 using the same material, used to bear the horizontal section of the L-shaped sliding groove 43 and increase the mechanical strength of the sliding groove 43. The sliding block 52 is fixedly connected with the secondary fixed assembly 5, and its shape matches the inner cavity profile of the L-shaped sliding groove 43, and always keeps in contact with the contact surface of the sliding groove 43 during the sliding process.

[0064] Specifically, when the secondary fixed assembly 5 moves up and down relative to the main fixed assembly 4, the sliding block 52 moves up and down along the vertical section of the L-shaped sliding groove 43. At this time, the support of the protruding plate 44 on the horizontal section of the sliding groove 43 can prevent the sliding groove 43 from deforming due to stress, wherein the inner wall of the vertical section limits the horizontal displacement of the sliding block 52, and then the sliding block 52 moves along the horizontal section, so that the front end faces of the main fixed assembly 4 and the secondary fixed assembly 5 can be coincided, facilitating the cooperation of the main guide groove unit 41 and the secondary guide groove unit 51.

[0065] This structure makes the secondary fixed assembly 5 unable to rotate or deviate laterally when moving, ensuring that the front end faces of the secondary fixed assembly 5 and the main fixed assembly 4 always keep in plane coincidence, so that the main guide groove unit 41 and the secondary guide groove unit 51 are accurately aligned to form a complete guide groove.

[0066] Further, as shown in Figure 7 The two ends of the L-shaped sliding groove 43 are respectively provided with elastic limiting blocks 8.

[0067] The elastic limiting block 8 refers to a blocking component made of compressible material, which can be realized by using rubber or silicone material. The component is fixed at the end of the sliding groove 43 by interference fit, and elastically deforms to provide a buffer resistance when the sliding block 52 contacts.

[0068] Specifically, when the secondary fixed assembly 5 drives the sliding block 52 to move along the L-shaped sliding groove 43, the elastic limiting block 8 is compressed and deformed when the sliding block 52 approaches the end of the groove. When the sliding block 52 reaches the predetermined position, the restoring force of the elastic limiting block 8 forms a reverse resistance to prevent the sliding block 52 from continuing to move, so as to ensure that the secondary fixed assembly 5 is fixedly arranged.

[0069] Further, as shown in Figure 10 The secondary fixed assembly 5 is provided with at least one group, and the multiple groups of secondary fixed assemblies 5 are connected with each other in the same way as the connection between the main fixed assembly 4 and the secondary fixed assembly 5.

[0070] Wherein, the sub-fixed assembly 5 is provided with at least one set of fixed devices, which means that in addition to the main fixed assembly 4, one or more sub-fixed units can be configured, which can be realized by the cooperation of the sliding groove 43 and the sliding block 52, and the pipeline storage space is expanded by hierarchical superposition.

[0071] The connection between multiple sets of sub-fixed assemblies 5 means that adjacent sub-fixed assemblies 5 are mechanically connected through a unified interface, which can be realized by using the same sliding groove 43 and sliding block 52 structure as the main fixed assembly 4 to ensure the structural compatibility of the expansion assembly.

[0072] The connection mode is the same as that of the main fixed assembly 4 and the sub-fixed assembly 5, which means that all expansion assemblies use a unified standard for connection interfaces, which can be realized by using the L-shaped sliding groove 43 and the sliding block 52 to realize the connection, and the position is locked by the elastic limiting block 8 to maintain the stability of the connection.

[0073] Specifically, when the pipeline storage capacity needs to be increased, a set of sub-fixed assemblies 5 can be stacked below the main fixed assembly 4, the sliding block 52 is embedded in the sliding groove 43 to complete the preliminary positioning, and the elastic limiting block 8 is automatically inserted into the end of the sliding groove 43 to realize fixation. If further expansion is needed, new sub-fixed assemblies 5 can be stacked below the installed sub-fixed assemblies 5, and the same connection steps are repeated. The guide groove unit between each assembly is spliced to form a continuous pipeline channel, and the guide unit 6 is adjusted along the moving groove 42 to adapt to different pipeline arrangement requirements.

[0074] Further, as shown in Figures 8-9 The upper end of the main fixed assembly 4 is provided with a clamping assembly 9 at a position corresponding to the main guide groove unit 41.

[0075] The clamping assembly 9 includes a support plate 91 fixedly arranged on the upper end of the main fixed assembly 4, a clamping plate 92 slidably arranged inside the support plate 91 and used for cooperating with the arterial pipeline or the venous pipeline, and a pressure sensing unit 93 connected with the clamping plate 92.

[0076] Wherein, the clamping plate 92 can be realized by using an elastic material with anti-slip lines on the surface, which can buffer the tension received by the pipeline through sliding displacement, and an anti-slip groove can be opened in the clamping plate 92, which can be realized by using a wave-shaped or zigzag-shaped pattern to increase the friction coefficient of the contact surface to prevent the pipeline from slipping off. The pressure sensing unit 93 is a sensor for detecting the force of the clamping plate 92, which can be realized by using a piezoelectric film or a strain gauge, and its signal output end is connected with the control module. When the pressure exceeds the preset threshold, an alarm is triggered.

[0077] Specifically, the clamping plate 92 is embedded inside the support plate 91 through a sliding rail structure, and remains stationary when not subjected to external force. When the pipeline is stored, the end is clamped into the anti-skid groove of the clamping plate 92, and at this time the texture of the anti-skid groove forms multi-point contact with the surface of the pipeline to avoid displacement of the pipeline after being fixed. When the pipeline is subjected to abnormal pulling, the clamping plate 92 slides along the sliding rail of the support plate 91, and the displacement causes the pressure sensing unit 93 to be compressed or stretched. The pressure sensing unit 93 converts the mechanical signal into an electrical signal and transmits it to the control module. When the electrical signal intensity exceeds the preset threshold, the control module activates the audible and visual alarm device. Since the clamping assembly 9 is located at the front end of the device, it is fixed at the end during the pipeline storage operation to avoid the risk of pulling due to shaking of the unfixed part during subsequent operations.

[0078] Working process:

[0079] First, the fixed support 1 is installed on the support rod 3 such as a bed fence through the clamping unit 2, and the clamping force is adjusted to ensure that the device is firmly fixed.

[0080] Subsequently, according to the length requirement of the pipeline, the auxiliary fixing assembly 5 is pulled out, the main guide groove unit 41 at the front end of the main fixing assembly 4 is aligned and spliced with the auxiliary guide groove unit 51 at the front end of the auxiliary fixing assembly 5, and a continuous guide groove 7 channel is formed.

[0081] Next, the arterial pipeline and the venous pipeline are respectively placed into the parallel guide grooves 7 corresponding to the main guide groove unit 41 and the auxiliary guide groove unit 51, and the guide unit 6 is used for multi-point limiting. By pushing the guide unit 6 horizontally, the first guide part 63 and the second guide part 64 are respectively rested on the arterial pipeline and the venous pipeline, ensuring that the two pipelines are arranged in parallel in the guide groove without crossing and winding.

[0082] When the auxiliary fixing assembly 5 slides into the main fixing assembly 4 front end surface, the sliding block 52 slides along the L-shaped sliding groove 43 and is clamped by the elastic limiting block 8 to realize positioning and locking, ensuring that the guide groove structure is completely connected.

[0083] If the fixed length needs to be increased, new auxiliary fixing assemblies 5 can be stacked under the installed auxiliary fixing assembly 5, and the same steps are repeated.

[0084] After the operation is completed, the clamping assembly 9 arranged at the upper end of the main fixing assembly 4 is adjusted to flexibly clamp the end of the pipeline, and the stress condition is monitored through the pressure sensing unit 93. Once the pipeline is subjected to excessive pulling force, the alarm is automatically triggered to remind medical staff.

[0085] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent ones. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
