Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and particularly relates to an examination bed facilitating PICC dressing change. Background Art

[0002] PICC dressing change is a process of maintaining and replacing dressings for a central venous catheter inserted peripherally. This is a common intravenous therapy method for patients undergoing long-term infusion, chemotherapy, or nutritional support. During the dressing change, the patient lies on the examination bed with the arms outstretched, and may be opened at 90 degrees relative to the trunk, facilitating the medical staff to change the dressing. However, the existing examination beds are usually relatively narrow, which is not conducive to supporting the outstretched arms. For patients with a larger body size, it is even impossible to support the arms, making it inconvenient to change the dressing during PICC care. Summary of the Invention

A plurality of first vertical rods 23 are distributed on both sides of the upper groove 21 and the lower groove 22. The top end of the first vertical rod 23 is fixedly connected to the side wall of the upper groove 21, and the bottom end is fixedly connected to the side wall of the lower groove 22; the support frame 30 includes an upper slide plate 31, a lower slide plate 32 and a second vertical rod 33. A plurality of second vertical rods 33 are fixedly arranged between the upper slide plate 31 and the lower slide plate 32. The upper slide plate 31 is U-shaped. The top end and the side wall of the upper slide plate 31 are slidably connected to the upper groove 21, and the lower slide plate 32 is slidably connected to the lower groove 22. The arm pillow device 40 is installed in the upper slide plate 31. The moving frame 20 can move along the length of the bed body 10 in the bed body 10. Whether the patient's head faces the head of the bed or the foot of the bed, the moving frame 20 can be moved to the head side of the patient; the support frame 30 can slide along the width direction of the bed body 10 in the moving frame 20. Pull the support frame 30 from the moving frame 20 to one side of the bed body 10. Whether it is the patient's left arm or right arm, PICC dressing change can be carried out.

[0028] The armrest device 40 includes an armrest 41, guide posts 42, a rack 43, and a rack fixing device. A plurality of guide posts 42 are installed at the bottom end of the armrest 41. The guide posts 42 pass through the upper slide plate 31 and are movably connected to the upper slide plate 31. The rack 43 is installed in the middle of the bottom end of the armrest 41.

After the dressing change is completed, the connecting rod 4414 is pulled at the bottom end of the upper slide plate 31 by hand. The connecting rod 4414 compresses the spring 442, so that the first slide rod 4411, the second slide rod 4412, and the third slide rod 4413 slide at the bottom end of the upper slide plate 31, and further the clamping teeth 44111 are disengaged from the clamping with the rack 43. The armrest 41 is lowered into the upper slide plate 31 along the guide posts 42, and then the support frame 30 is pushed into the moving frame 20 to complete the storage.

[0030] Optionally, in an embodiment, a plurality of first sliding grooves 111 are provided on the bed board 11, and a plurality of first roller devices 50 are correspondingly provided at the top end of the upper groove 21. The first roller devices 50 are movably connected in the first sliding grooves 111; a second sliding groove 121 is provided on the support rod 12, and a plurality of second roller devices 60 are correspondingly provided at the bottom end of the lower groove 22; the second roller devices 60 are movably connected in the second sliding groove 121. The first roller device 50 includes a first roller 51 and a first bracket 52. The first roller 51 is rotatably connected to the first bracket 52; the first bracket 52 is installed at the top end of the upper groove 21 and is slidably connected to the side wall of the first sliding groove 111, and the first roller 51 is in rolling connection with the top wall of the first sliding groove 111. The second roller device 60 includes a second roller 61 and a second bracket 62. The second roller 61 is rotatably connected to the second bracket 62; the second bracket 62 is installed at the bottom end of the lower groove 22 and is slidably connected to the side wall of the second sliding groove 121, and the second roller 61 is in rolling connection with the bottom wall of the second sliding groove 121. The moving frame 20 realizes the convenient movement of the support frame 30 on the bed body 10 by means of the first roller 51 and the second roller 61 at the top end.

[0031] Optionally, in an embodiment, an examination bed convenient for PICC dressing change further includes a magnetic attraction device 70. The magnetic attraction device 70 includes a first magnet 71 and a second magnet 72. A plurality of first magnets 71 are respectively installed on the side walls of the legs of the bed body 10, and a plurality of second magnets 72 are installed on the two side walls of the lower groove 22. The first magnet 71 and the second magnet 72 are magnetically connected. By magnetically connecting the second magnet 72 on the moving frame 20 with the first magnet 71 at one end of the bed body 10, the bed body 10 can be fixed on this side.

[0032] An examination bed convenient for PICC dressing change further includes movable casters 80. A plurality of movable casters 80 are respectively installed on the legs of the bed body 10. The movable casters 80 are of the prior art and are provided with a locking function, that is, it is convenient for the movement of the vehicle body and can also fix the position of the vehicle body.

[0033] Working principle: When changing the PICC dressing for a patient, the patient lies randomly on the bed body 10. The moving frame 20 is moved to the head side of the patient, and the second magnet 72 on the moving frame 20 is magnetically connected to the first magnet 71 on this side to fix the position of the moving frame 20. The support frame 30 is moved from the moving frame 20 to the side of the patient's arm where the dressing needs to be changed. The armrest 41 is pulled up from the upper slide plate 31 to be flush with the bed surface, and the height of the rack 43 and the armrest 41 is fixed through the engagement of the engaging teeth 44111 and the rack 43 to support the patient's arm where the dressing needs to be changed. After the dressing change is completed, the connecting rod 4414 is pulled at the bottom of the upper slide plate 31 by hand. The connecting rod 4414 compresses the spring 442, causing the first slide rod 4411, the second slide rod 4412, and the third slide rod 4413 to slide at the bottom of the upper slide plate 31, so that the engaging teeth 44111 are disengaged from the engagement with the rack 43, and the armrest 41 is lowered into the upper slide plate 31 along the guide post 42. Then, the support frame 30 is pushed into the moving frame 20 to complete the storage.
