Description

Technical Field

[0001] The present invention relates to the technical field of dialysis tube fixing, and in particular to a dialysis tube fixer with a protective function. Background Art

[0002] Dialysis tubing is primarily a central venous catheter, serving as a form of temporary vascular access, primarily for patients undergoing hemodialysis for acute or chronic renal failure. To ensure proper function and prevent the tubing from vibrating during dialysis, thus minimizing the pain it can cause the patient, a simple fixator is required to secure the tubing.

[0003] For example, the Chinese invention patent with patent number 201811529577.6 provides a dialysis tube fixing device, which is used to limit the position of the dialysis tube through a lower fixing device, so that the dialysis tube can adjust the relative position in real time as needed, while ensuring the fixing effect of the dialysis tube fixing device. However, through analysis of the above patents and in combination with the prior art, it is found that traditional dialysis tube holders mostly use rigid fixation. When the patient's limbs move or medical staff pulls the dialysis tube by mistake, there is no buffering energy dissipation structure to buffer the movement of the dialysis tube, resulting in the instantaneous movement speed of the dialysis tube being too large and generating a large shear force between the clamping member, making the dialysis tube prone to breakage and damage. Therefore, in view of this, a dialysis tube holder with a protective function is provided. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The dialysis tube holder is worn on a patient's limb for use. During use, if a single dialysis tube is pulled, the second mounting shell and the shielding plate can be driven to rotate along the connecting axis. During the rotation of the second mounting shell, its movement is buffered by the first buffer assembly. When the dialysis tube is subjected to a pulling force in a direction perpendicular to the plane of the third mounting shell, the third mounting shell moves in a direction perpendicular to the plane of the second mounting shell, and the movement of the third mounting shell is buffered by the second buffer assembly. When the dialysis tube is subjected to a pulling force along the direction of its clamping axis, the two groups of clamping plates are driven to move, and the movement of the two groups of clamping plates can be buffered by the third buffer assembly. Therefore, by buffering the dialysis tube in multiple directions, the dialysis tube can be effectively protected, and the dialysis tube can be prevented from being damaged due to excessive instantaneous movement speed, thereby improving the practical value of the dialysis tube holder.

[0016] 2. When the dialysis tube holder is in use, when a single dialysis tube is pulled, the shielding plate can be driven to rotate a certain range along the connecting axis. During the rotation process, the shielding plate squeezes the first buffer springs on the two sets of arc rods through the retaining ring, thereby buffering the movement of the shielding plate to a certain extent through the elastic reset ability of the first buffer spring, and then buffering the movement of the dialysis tube, thereby preventing the dialysis tube from being damaged due to excessive instantaneous movement speed.

[0017] 3. When the dialysis tube holder is in use, when the dialysis tube is subjected to a pulling force in the vertical direction of the mounting plate and moves, the third mounting shell can be driven to move in a direction perpendicular to the mounting plate. The movement trajectory of the third mounting shell cannot be deviated due to the cooperative positioning of the positioning rod and the positioning cylinder. During the movement, the third mounting shell drives the two sets of sliding cylinders to slide on the support rod through the cooperation of the hinge seat and the two sets of connecting rods, thereby squeezing the second buffer spring. The reset ability of the two sets of second buffer springs buffers the movement of the third mounting shell, thereby buffering the movement of the dialysis tube in the other direction, thereby further avoiding damage to the dialysis tube due to excessive instantaneous movement speed.

[0018] 4. During use, when the dialysis tube holder is subjected to a pulling force along the axis of the two sets of clamping plates, causing the clamping plates to move, the friction between the clamping plates and the anti-slip pads causes the clamping plates to follow suit. During this movement, a slider on one side of the clamping plate slides laterally along the two sets of positioning ridges, and the slider can slide on the mounting rod. During this movement, the slider compresses one set of third buffer springs, thereby cushioning the movement of the clamping plate through the reset capability of the third buffer spring, effectively preventing the dialysis tube from breaking or being damaged during the pulling movement.

DETAILED DESCRIPTION

[0031] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0032] Example:

[0033] like Figure 1 、 Figures 5 to 8 As shown, the present invention provides a dialysis tube holder with a protective function, which includes a first mounting shell 101, a second mounting shell 201 and a third mounting shell 301 stacked in sequence. When the dialysis tube holder is used, it is fixed to the patient's arm through the Velcro strap 106 at the bottom of the first mounting shell 101. A mounting plate 401 is fixed in the third mounting shell 301. Two groups of fixedly mounted first connecting seats 402 and two groups of slidably connected second connecting seats 403 are provided on the mounting plate 401. Each group of first connecting seats 402 is arranged opposite to one group of second connecting seats 403. An arc-shaped shell 502 is provided on each of the first connecting seats 402 and the second connecting seat 403. A slidably connected clamping plate 601 is provided on one side of the arc-shaped shell 502. Every two groups of clamping plates 601 form a cavity for clamping the dialysis tube. The dialysis tube is stably clamped and fixed by the two groups of oppositely arranged clamping plates 601.

[0034] like Figure 7 、 8As shown, in this embodiment, a shielding plate 202 is provided on the second mounting shell 201, and the shielding plate 202 is rotatably connected to the first mounting shell 101 via a connecting shaft 206. A first buffer assembly is provided in the first mounting shell 101 and connected to the shielding plate 202. The first buffer assembly includes four groups of arc-shaped rods 102, one end of each of the four groups of arc-shaped rods 102 is welded to the inner bottom of the first mounting shell 101, and a stopper 103 is fixedly provided at the other end. The axis of the arc-shaped rod 102 coincides with the axis of the connecting shaft 206. A first buffer spring 104 is sleeved on each of the four groups of arc-shaped rods 102, and a stopper ring 105 is provided at one end of the first buffer spring 104. Four groups of through slots 205 are formed on the shielding plate 202, and the four groups of stoppers 103 are respectively disposed in the four groups of through slots 205. The bottom surface of the shielding plate 202 and the bottom surface of the stopper 103 are both in contact with the stopper ring 105.

[0035] When a single set of dialysis tubing is pulled, an outward pulling force is applied to one end of the shielding plate 202, causing it to rotate along the connecting shaft 206. During the rotation of the shielding plate 202, two sets of curved rods 102 are inserted into two sets of through slots 205, while the other two sets of curved rods 102 are released from the two sets of through slots 205. A certain gap exists between the through slots 205 and the block 103, providing space for its movement. During its movement, the shielding plate 202 cooperates with the retaining ring 105 to compress the two sets of first buffer springs 104. The reset capacity of the two sets of first buffer springs 104 cushions the movement of the shielding plate 202, reducing the instantaneous tensile force on the dialysis tubing and effectively protecting it.

[0036] like Figure 5 、 6 As shown in Figures 7 and 8, in this embodiment, the third mounting shell 301 is arranged in the second mounting shell 201, and the third mounting shell 301 is arranged parallel to the second mounting shell 201. A second buffer component is provided in the second mounting shell 201 and connected to the third mounting shell 301. The second buffer component elastically buffers the movement of the third mounting shell 301 in a direction perpendicular to its plane. The second buffer assembly includes two groups of second buffer springs 307 and four groups of connecting rods 305. Four groups of hinged seats 304 are provided at the bottom of the third mounting shell 301, and every two groups of hinged seats 304 are arranged adjacent to each other. One end of the four connecting rods 305 is hinged to the four groups of hinged seats 304 respectively, and the other end is provided with a hinged slide 306. Two groups of second slide grooves 203 are opened at the bottom of the second mounting shell 201, and a fixedly installed support rod 204 is provided at the bottom of the second slide groove 203. The four groups of slides 306 are arranged in groups of two on the two groups of support rods 204. The two groups of second buffer springs 307 are respectively arranged on the two groups of support rods 204, and the two ends of the second buffer spring 307 are respectively in contact with the two groups of slides 306.

[0037] When the dialysis tube is subjected to a pulling force perpendicular to the third mounting shell 301 and moves, it drives the third mounting shell 301 to move. During this movement, the third mounting shell 301 cooperates with the hinge seat 304 and the connecting rod 305 to control the two sets of slide cylinders 306 to move inward from their ends on one set of support rods 204. During this movement, the two sets of slide cylinders 306 squeeze the second buffer spring 307, effectively buffering the pulling force on the third mounting shell 301 and the dialysis tube, further protecting the dialysis tube.

[0038] like Figure 3 、 9 As shown, in this embodiment, the slider 602 on one side of the clamping plate 601 is connected to the arc-shaped shell 502 via a third buffer assembly, which is used to buffer the movement of the clamping plate 601 in a direction parallel to the arc-shaped shell 502. The third buffer assembly includes a mounting rod 504. A support frame 503 is provided on one side of the arc-shaped shell 502. The mounting rod 504 is inserted into the support frame 503, and one end of the mounting rod 504 is fixed to one side of the support frame 503 via a threaded fit. Two sets of third buffer springs 505 are sleeved on the mounting rod 504, and the slider 602 is sleeved on the mounting rod 504. One end of the two sets of third buffer springs 505 respectively contacts the inner wall of the support frame 503, and the other end contacts the two ends of the slider 602.

[0039] When one end of the dialysis tube is pulled, the dialysis tube tends to move along the axis of the two sets of clamping plates 601. Since the inner side of the clamping plates 601 is provided with an anti-slip pad 604 for increasing friction, the dialysis tube and the clamping plates 601 are prevented from sliding relative to each other. As the dialysis tube moves under the pulling force, the two sets of clamping plates 601 can be driven to move. During the movement of the clamping plates 601 on one side of the arcuate shell 502, the slider 602 on one side moves along the mounting rod 504, thereby squeezing one set of the third buffer springs 505. The reset ability of the third buffer springs 505 buffers the force exerted on the clamping plates 601 and the dialysis tube in the axis direction of the clamping plates 601, thereby further preventing damage to the dialysis tube. This also allows patients or medical staff to promptly sense changes in the force applied to the dialysis tube and promptly stop the current movement, effectively improving the protection of the dialysis tube.

[0040] like Figure 6 、 7As shown, in this embodiment, a positioning rod 302 is provided at the bottom of the third mounting shell 301, and a positioning cylinder 207 is provided at the bottom of the second mounting shell 201. The positioning rod 302 is inserted into the positioning cylinder 207, and two sets of stoppers 303 at one end of the positioning rod 302 are respectively retained in two sets of stop slots 208 provided in the positioning cylinder 207. The movement of the third mounting shell 301 is maintained parallel to the second mounting shell 201 by the cooperation and positioning of the positioning rod 302 at its bottom and the positioning cylinder 207 at the inner bottom of the second mounting shell 201, thereby improving the stability of the internal structure of the dialysis tube holder. The cooperation of the two sets of stoppers 303 at one end of the positioning rod 302 and the two sets of stop slots 208 provided in the positioning cylinder 207 prevents the positioning rod 302 from disengaging from the positioning cylinder 207, further improving the stability of the internal structure of the dialysis tube holder.

[0041] like Figure 9 As shown, in this embodiment, positioning grooves 603 are formed at both the upper and lower ends of the slider 602, and positioning ridges 506 are provided on both sides of the inner wall of the support frame 503. The slider 602 is slidably connected to the support frame 503 through two sets of positioning grooves 603, which are respectively engaged with two sets of positioning ridges 506. The movement of the slider 602 is fixed by the cooperation between the positioning grooves 603 and the positioning ridges 506 on both sides of the inner wall of the support frame 503, preventing the slider 602 and the clamping plate 601 from deviating, thereby improving the stability of the internal structure of the fixture.

[0042] like Figures 2 to 5 As shown, in this embodiment, the two groups of second connecting seats 403 are connected to the mounting plate 401 through an opening component, which includes a first wedge plate 405 and a second wedge plate 408. The inclined surface of the first wedge plate 405 contacts the inclined surface of the second wedge plate 408. A connecting frame 404 is provided on one side of the first wedge plate 405. Four groups of guide grooves 501 are provided on the mounting plate 401. Two groups of protrusions are provided at the bottom of the two groups of second connecting seats 403. The four groups of protrusions are clamped. In the four groups of guide grooves 501, the four groups of protrusions are fixedly connected to the connecting frame 404. A first vertical plate 406 is provided at the bottom of the connecting frame 404. A second vertical plate 308 is provided in the third mounting shell 301. An elastic frame 407 is provided between the first vertical plate 406 and the second vertical plate 308. An opening plate 410 connected by an L-shaped rod 409 is provided on one side of the second wedge plate 408. The L-shaped rod 409 is slidably clamped in the L-shaped groove 309 opened on the third mounting shell 301.

[0043] By moving the opening plate 410, the L-shaped rod 409 can be driven to slide along the L-shaped groove 309, thereby causing the second wedge plate 408 to move linearly. The second wedge plate 408 can then cooperate with the inclined surface of the first wedge plate 405 to control the lateral movement of the two sets of second connecting seats 403, thereby controlling the opening of the two clamping plates 601 until the flat surface at one end of the second wedge plate 408 contacts the flat surface at one end of the first wedge plate 405, thereby fixing the position of the two sets of second connecting seats 403 after opening, facilitating the placement or removal of the dialysis tube. By moving the opening plate 410 in the opposite direction, the fixed position of the second connecting seats 403 is released, and the elastic frame 407 controls the two sets of second connecting seats 403 to return to their original position, thus completing the stable clamping of the dialysis tube.

[0044] like Figure 9 As shown, in this embodiment, a curved plate 507 is provided on one side of the curved housing 502 and is detachably mounted via bolts. The slider 602 is slidably engaged in a first sliding groove 508 provided on the curved plate 507. The curved plate 507 is used to block an opening on one side of the curved housing 502, thereby minimizing the risk of foreign objects entering the curved housing 502 and interfering with the movement of the slider 602.

[0045] The specific working principle and beneficial effects of the present invention are as follows:

[0046] The dialysis tube holder is secured to the patient's arm via a Velcro strap 106. The elastic frame 407 pushes the two sets of second connectors 403 and first connectors 402 together, controlling the closing of the two opposing clamping plates 601 to securely clamp the dialysis tube, facilitating dialysis treatment. During clamping, one end of the tube is bent to allow for movement, preventing the tube from detaching from the patient's body.

[0047] When a single set of dialysis tubes is pulled, the movement of the dialysis tubes drives the second mounting shell 201 and the third mounting shell 301 to rotate simultaneously along the connecting shaft 206, and the shielding plate 202 on the second mounting shell 201 squeezes the first buffer spring 104, thereby buffering the movement of the dialysis tubes through the reset ability of the first buffer spring 104. When the two sets of dialysis tubes are subjected to a pulling force perpendicular to the plane of the third mounting shell 301, the two sets of slides 306 are driven to close on the support rod 204 through the cooperation of the hinge seat 304 and the connecting rod 305 to squeeze the second buffer spring 307, thereby buffering the movement of the dialysis tubes through the reset ability of the second buffer spring 307. When the dialysis tube is subjected to a pulling force along its axis and moves, the two groups of clamping plates 601 are driven to slide on the inner side of the two groups of arc-shaped shells 502. The slider 602 on one side of the clamping plate 601 squeezes the third buffer spring 505 in the arc-shaped shell 502, thereby buffering the movement of the clamping plate 601 and the dialysis tube along its axis through the reset ability of the third buffer spring 505.

[0048] This dialysis tube holder utilizes a multi-stage buffering structure to buffer and dissipate energy during the movement of the dialysis tube in all directions, effectively preventing the tube from breaking or deforming due to excessive instantaneous movement when pulled. This allows patients or medical staff to promptly sense changes in the force applied to the tube and halt its movement, protecting the tube. Furthermore, the dialysis tube holder boasts a simple and stable internal structure, is easy to use, and offers high practical value.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
