Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to an adjustable stent suitable for seated hemodialysis. Background Technology

[0002] In the current medical environment, some patients in the hemodialysis unit experience physical inconveniences. For example, some patients have abnormally swollen abdomens due to their condition. Generally, when undergoing hemodialysis, patients lie supine on the bed, which causes heavy pressure on the internal organs, making it difficult for patients to breathe and causing discomfort. Although the bed may be rocked up partially, it does not provide sufficient support for the patient's lower back and makes it easy for them to slip off. Moreover, the needles used in hemodialysis are very thick, and patients cannot move their arms freely during hemodialysis. When patients want to maintain a sitting position on the bed, there is nowhere for their arms to support them. Therefore, a technical solution is needed to solve the above problems.

The strap 124 is telescopic. In this embodiment, the base plate 1 can be placed on a hospital bed, with the two side plates 12 located on both sides of the hospital bed. The strap 124 is stretched and passes under the hospital bed. The hook 122 is hung in the buckle hole 121 located on the other side plate 12 of the hospital bed, and then the strap 124 is tightened to fix the base plate 1 to the hospital bed.

[0024] The backrest assembly 2 is mounted on the base plate 1. The backrest assembly 2 includes a cushion 22, two support frames 21, and a drive device 23. The support frames 21 are fixedly mounted on the upper surface of the base plate 1. The backrest assembly 2 is located on the back side of the seat cushion 11. The cushion 22 is mounted between the two support frames 21. The support frames 21 are provided with a shaft 211. The cushion 22 includes a connecting plate 221, which is located on the back side of the cushion 22. The connecting plate 221 is provided with a waist-shaped hole 222. The shaft 211 passes through the waist-shaped hole 222 and can move within the range of the waist-shaped hole 222. When the cushion 22 is perpendicular to the seat cushion 11, the shaft 211 is located at the lowest end of the waist-shaped hole 222. When the lower end of the cushion 22 gradually moves away from the waist-shaped hole 222, the shaft 211 moves within the range of the waist-shaped hole 222. During the process, the shaft 211 moves upward within the range of the waist-shaped hole 222. The drive device 23 is fixedly installed on the base plate 1. The drive device 23 is located on the back side of the cushion 22. The cushion 22 is provided with a hinge part 223. The push rod 231 of the drive device 23 is hinged to the hinge part 223. The cushion 22 is located above the seat cushion 11. The cushion 22 can tilt. The lower end of the cushion 22 can move in the horizontal direction. The drive device 23 is an electric telescopic rod. The drive device 23 and the shaft 211 cooperate with the waist-shaped hole 222 so that the lower end of the cushion 22 can maintain horizontal movement during the tilting adjustment of the cushion 22, so that the cushion 22 can always support the patient's lower back during the adjustment of the angle.

[0025] More preferably, this embodiment also includes a headrest 6, a backrest 22 with a guide tube 224, a telescopic rod 61 on the headrest 6, the telescopic rod 61 being inserted into the guide tube 224, the headrest 6 being installed on the upper end of the backrest 22, the headrest 6 being able to move closer to or further away from the backrest 22, the headrest 6 being able to adjust its height through a pull-out structure, increasing the height of the backrest 22, and adjusting according to the position of different patients' heads to provide comfortable head support for patients.

[0026] The upper surfaces of the base plates 1 on both sides of the seat cushion 11 are mounting areas 13. The armrest assembly 3 is detachably mounted in the mounting area 13. The armrest assembly 3 includes a base 31 and an armrest plate 32. The base 31 is mounted on the base plate 1. The lower surface of the base 31 is provided with two insert rods 314. The base plate 1 is provided with multiple through holes 131, which are arranged along the length of the mounting area 13. Each through hole 131 corresponds to a latch 4. The base plate 1 includes a mounting cavity 14, in which the latch 4 is installed. The latch 4 includes a button 41 and a retaining plate 42. At least a part of the button 41 is located on the outer side of the protruding side plate 12. A spring 5 is installed between the retaining plate 42 and the side wall of the mounting cavity 14. The side wall of the mounting cavity 14 is provided with a first fixing groove 141, and the side wall of the retaining plate 42 is provided with a second fixing groove 422. The two ends of the spring 5 are respectively installed in the first fixing groove 141 and the second fixing groove. Inside 422, the insertion rod 314 is provided with a slot 3141, and the locking plate 42 is provided with a locking block 421 corresponding to the slot 3141. The upper edge of the locking block 421 is rounded, and the lower end of the insertion rod 314 is arc-shaped. When the insertion rod 314 is inserted into the through hole 131, it can better press the locking block 421 to lock. By pressing the button 41 to move the button 41 into the mounting cavity 14, the compression spring 5 causes the locking block 421 to disengage from the slot 3141. When the button 41 locking the two insertion rods 314 is pressed at the same time, the locking blocks 421 of the two latches 4 disengage from the corresponding slots 3141 of the insertion rod 314, and the handrail assembly 3 can be removed from the base plate 1. The handrail assembly 3 can change its front and back position on the same mounting area 13 to adapt to the position of the patient's arm, and can also change its position between two mounting areas 13 to adjust according to the different arm positions of the patient when performing hemodialysis.

The guide rod 321 is at least partially located in the guide groove 311 and can move along the guide groove 311. The base 31 is provided with a plurality of limiting holes 312, which are arranged along the length of the guide groove 311. The limiting holes 312 can be used to insert pins 313, which abut against the lower end of the guide rod 321. The armrest 32 is used to support the patient's arm. By adjusting the pins 313 inserted into the limiting holes 312 at different heights, the height of the guide rod 321 is limited. The armrest 32 can be adjusted up and down according to the height of the patient's arm, making it suitable for patients of different heights to place their arms.

[0028] More preferably, an extension plate 33 is installed at the end of the armrest 32 away from the backrest 22. The extension plate 33 is rotatably connected to the armrest 32. The upper surface of the extension plate 33 is flush with the upper surface of the armrest 32. The extension plate 33 can be adjusted according to the degree of bending of the patient's arm during hemodialysis to provide a suitable arm support plane for the patient. Soft pads can be installed on the upper surfaces of both the armrest 32 and the extension plate 33 to make the arm placement more comfortable.
