Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically, it relates to a structure for a non-slip pad for fixing the arm of a patient in a hemodialysis room. Background Technology

[0002] During hemodialysis treatment, patients need to keep their puncture-side arm still for extended periods to prevent needle displacement, dislodgement, bleeding, hematoma, or even treatment interruption. The anti-slip pad for the patient's arm in the hemodialysis unit is a crucial medical auxiliary device. Its core function is to provide stable support and fixation for the patient's puncture-side arm. Its design, conforming to the arm's contour, limits the arm's range of motion, while the fixation components enhance the relative stability between the arm and the pad.

[0003] However, the existing anti-slip mats have a fixed angle and can only be laid flat on the dialysis bed. The angle cannot be adjusted. When the patient adjusts to a semi-recumbent position with the dialysis bed, the mat cannot be adjusted with the tilt of the bed surface, which makes it impossible to place the arm horizontally. This increases the difficulty of puncture, causes uneven force on the limb, and makes it easy to shift due to gravity. At the same time, it interferes with the medical staff's observation and care of the puncture point.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the problem that existing anti-slip mats have a fixed angle, can only be laid flat on the dialysis bed, and cannot be adjusted in angle, and when the patient adjusts to a semi-recumbent position with the dialysis bed, the mat cannot be adjusted to tilt with the bed surface, making it impossible to place the arm horizontally. This increases the difficulty of puncture, causes uneven force on the limb, makes it prone to shifting due to gravity, and interferes with medical staff's observation and care of the puncture site, the basic concept of the technical solution adopted in this utility model is as follows:

[0006] A structure for fixing an anti-slip pad for a patient's arm in a hemodialysis room includes an anti-slip pad, a bracket, and an adjustable fixing component. The anti-slip pad has two symmetrically connected connecting blocks at its bottom. Each connecting block has a rotational positioning structure for cooperating with the bracket to adjust and lock the angle of the anti-slip pad. The upper surface of the anti-slip pad has a placement groove for placing the arm. The adjustable fixing component includes a first fixing rod, a second fixing rod, and a fixing strap disposed on the anti-slip pad. The first and second fixing rods are respectively located on both sides of the placement groove.

[0007] In a preferred embodiment of this utility model, the rotary positioning structure includes a rotary shaft, a locking block, and a spring. The two connecting blocks are connected to the rotary shaft, and the bracket is rotatably mounted on the two rotary shafts. The bracket has two mounting slots, and a locking block is slidably mounted in each mounting slot. A guide rod is connected to the bottom of the locking block, and a spring is movably sleeved on the guide rod. Several locking slots that are adapted to the locking blocks are provided on the outer peripheral wall of the rotary shaft.

[0008] In a preferred embodiment of this utility model, a connecting rod is horizontally connected between the two card blocks.

[0009] In a preferred embodiment of the present invention, two fixing bands are slidably sleeved on the first fixing rod, and several fixing grooves are evenly distributed along the length of the second fixing rod.

[0010] In a preferred embodiment of this utility model, one end of the spring abuts against the bottom of the locking block, and the other end abuts against the bottom of the mounting groove.

[0011] In a preferred embodiment of this utility model, the placement groove is an arc-shaped groove, and the placement groove is opened in the middle of the upper surface of the anti-slip mat.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] In this invention, the bottom of the anti-slip mat has a rotational positioning structure formed by connecting blocks, rotating shafts and brackets. Combined with locking blocks, springs and connecting rods, the anti-slip mat can adjust its angle according to the patient's semi-reclining position and can automatically lock itself to prevent the position of the arm and the mat from changing due to the tilt of the bed, thus reducing the treatment risks caused by arm displacement.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 4 As shown, a patient arm fixation anti-slip mat structure in a hemodialysis room includes an anti-slip mat 1, a support 4, and an adjustable fixation component. The anti-slip mat 1 has two symmetrically connected connecting blocks 2 at its bottom. Each connecting block 2 has a rotational positioning structure for cooperating with the support 4 to adjust and lock the angle of the anti-slip mat 1. The upper surface of the anti-slip mat 1 has a placement groove 11 for placing the arm. The adjustable fixation component includes a first fixing rod 12, a second fixing rod 14, and a fixing strap 13, all mounted on the anti-slip mat 1. The first fixing rod 12 and the second fixing rod 14 are located on opposite sides of the placement groove 11. In this configuration, the two connecting blocks 2 at the bottom of the anti-slip mat 1 provide a mounting base for the rotational positioning structure, enabling the rotational positioning structure to stably connect the anti-slip mat 1 and the support 4. Combined with the support of the patient's arm from the placement groove 11, and the adjustable fixation component consisting of the first fixing rod 12, the second fixing rod 14, and the fixing strap 13, this ensures that after the arm is placed, it can be adapted to different sizes via the adjustable fixation component and its angle can be adjusted according to the tilt of the bed via the rotational positioning structure.

[0023] like Figures 1 to 4 As shown, in a specific embodiment, the rotary positioning structure includes a rotary shaft 3, a locking block 7, and a spring 9. Two connecting blocks 2 are connected to the rotary shaft 3. A bracket 4 is rotatably mounted on the two rotary shafts 3. Two mounting slots 6 are provided in the bracket 4, and a locking block 7 is slidably mounted in each mounting slot 6. A guide rod 8 is connected to the bottom of the locking block 7, and a spring 9 is movably sleeved on the guide rod 8. Several slots 5 that fit the locking blocks 7 are provided on the outer peripheral wall of the rotary shaft 3. In this configuration, the connecting blocks 2 drive the rotary shaft 3 to form a rotary engagement with the bracket 4, providing a rotational basis for adjusting the angle of the anti-slip pad 1. The mounting slots 6 provide sliding space for the locking blocks 7. The guide rod 8 limits the sliding direction of the locking blocks 7 and supports the spring 9. The spring 9, through its own deformation, pushes the locking blocks 7 to engage or disengage from the slots 5, thereby achieving locking and unlocking of the anti-slip pad 1 after angle adjustment.

[0024] like Figures 1 to 4 As shown, a connecting rod 10 is horizontally connected between the two locking blocks 7. In this configuration, the connecting rod 10 connects the two locking blocks 7, so that medical staff do not need to operate the two locking blocks 7 separately. They only need to push the connecting rod 10 to simultaneously drive the two locking blocks 7 to slide along their respective mounting slots 6.

[0025] like Figures 1 to 4As shown, furthermore, two fixing straps 13 are slidably sleeved on the first fixing rod 12, and several fixing grooves 15 are evenly distributed along its length on the second fixing rod 14. In this configuration, the fixing straps 13, through sliding cooperation with the first fixing rod 12, can adjust their position on the anti-slip mat 1 according to the length of the patient's arm. Combined with the fixing grooves 15 at different positions on the second fixing rod 14, the fixing straps 13 can fix different arms.

[0026] like Figures 1 to 4 As shown, one end of the spring 9 abuts against the bottom of the locking block 7, and the other end abuts against the bottom of the mounting groove 6. In this configuration, the bottom of the mounting groove 6 provides a fixed support end for the spring 9, allowing the spring 9 to contract when the locking block 7 is squeezed and slid by the rotating shaft 3. At the same time, when the locking groove 5 of the rotating shaft 3 is aligned with the locking block 7, the spring 9 can release its elastic force to push the locking block 7 into the locking groove 5 by means of the abutment relationship between its two ends and the locking block 7 and the bottom of the mounting groove 6 respectively, ensuring the stability of the locking and unlocking of the rotation positioning structure.

[0027] like Figures 1 to 4 As shown, the placement groove 11 is further defined as an arc-shaped groove, and is located in the middle of the upper surface of the anti-slip mat 1. In this configuration, the arc-shaped placement groove 11 in the middle of the upper surface of the anti-slip mat 1 conforms to the natural contour of the human arm, so that the arm can form a stable fit with the inner wall of the placement groove 11 after placement, reducing the sliding of the arm in the placement groove 11.

[0028] The implementation principle of the anti-slip pad structure for fixing a patient's arm in a hemodialysis room in this embodiment is as follows: When using the anti-slip pad for fixing a patient's arm in a hemodialysis room, first place the support 4 in a suitable position on the dialysis bed, so that the anti-slip pad 1 is kept in an initial horizontal state. Then guide the patient to place the puncture-side arm into the arc-shaped placement groove 11 in the middle of the upper surface of the anti-slip pad 1. If the patient needs to adopt a semi-recumbent position, the angle of the anti-slip pad 1 needs to be adjusted to adapt to the tilt of the bed. At this time, directly rotate the anti-slip pad 1. The two connecting blocks 2 symmetrically connected at the bottom of the anti-slip pad 1 will drive the rotating shaft 3 on it to rotate synchronously. During the rotation of the rotating shaft 3, the rotating shaft 3 and the slot 5 will squeeze the locking block 7 in the mounting groove 6 of the support 4. The slot 5 makes the anti-slip pad only rotate counterclockwise (towards...). Figure 4 Using the reference point, the locking block 7 slides along the mounting groove 6, and the guide rod 8 connected to the bottom of the locking block 7 moves synchronously. The spring 9 movably sleeved on the guide rod 8 is compressed and contracts. When the rotating shaft 3 rotates to the target angle, and a certain groove 5 on the outer peripheral wall of the rotating shaft 3 corresponds to the position of the locking block 7, the spring 9 is no longer compressed and returns to its original shape, pushing the locking block 7 to slide into the groove 5, thereby locking the angle of the anti-slip pad 1 and preventing the anti-slip pad 1 and the arm from changing position due to tilting force.

[0029] After the angle adjustment is completed, the adjustable fixing component is adjusted according to the length and thickness of the patient's arm. The two fixing straps 13 that are slidably sleeved on the first fixing rod 12 are pushed to move the fixing straps 13 to a suitable restraint position on the arm. Then, the end of the fixing strap 13 away from the first fixing rod 12 is wrapped around the second fixing rod 14 and embedded into the fixing groove 15 at the corresponding position on the second fixing rod 14 according to the arm size. The two ends of the fixing strap 13 are then attached and fixed by the Velcro on the fixing strap 13 to ensure that the arm is stably placed in the placement groove 11 and does not affect blood circulation.

[0030] When the treatment is finished and the support 4 needs to be stored or the anti-slip pad 1 needs to be adjusted back to a horizontal position, pull the connecting rod 10 that connects the two locking blocks 7 horizontally away from the rotating shaft 3. The connecting rod 10 will cause the two locking blocks 7 to slide synchronously along the mounting groove 6 and disengage from the locking groove 5 on the rotating shaft 3. At this time, the spring 9 will be compressed and contracted again. After the locking blocks 7 disengage from the locking groove 5, rotate the anti-slip pad 1 clockwise so that the anti-slip pad 1 drives the connecting block 2 and the rotating shaft 3 back to their initial positions. Release the connecting rod 10, and the spring 9 will restore its deformation and push the locking blocks 7 to reset. Then the support 4 can be stored, completing the entire usage process.
