Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a wheelchair convenient for echocardiogram examination. Background Art

[0002] Echocardiogram examination is a medical imaging examination technique that emits and receives ultrasonic signals through an ultrasonic probe (i.e., "transducer") and converts them into electrical signals, and converts information such as heart valves, heart chambers, ventricular walls, and blood flow into image information. It is the preferred examination method for evaluating cardiac structure and function clinically.

[0003] Echocardiogram examination is generally carried out on an examination bed. The long axis of the left ventricle, the short axis of the great artery, and the short axis sections at different levels of the left ventricle are collected in the left lateral decubitus position, and the apical section, subxiphoid section, and suprasternal notch section are collected in the supine position. For patients with no mobility or inconvenient mobility such as cerebral infarction and overweight, the process of moving from the wheelchair to the examination bed is very difficult, requiring the help of two or three people and taking a long time, and some patients cannot complete it; the process of returning to the wheelchair after the examination is also difficult. At this time, most patients are directly examined while sitting on the wheelchair. However, ordinary wheelchairs are neither convenient for ultrasound doctors to examine nor can patients assume various positions according to the examination requirements. The limited acoustic window of the heart can cause unclear image display, which is not conducive to the accurate evaluation of cardiac structure and function. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides the following technical solutions:

[0005] A wheelchair convenient for echocardiogram examination, the wheelchair includes a seat board, a leg board, a back board, a bracket, and armrests. The two ends of the seat board are respectively rotatably connected to the back board and the leg board, and the seat board, the leg board, and the back board are connected together through the armrests. The back board and the leg board are driven to rotate synchronously by rotating the armrests;

[0006] A seat cushion is rotatably connected to the seat board. Support plates are rotatably installed on both sides of the back board, and a side-lying assistance component is arranged at the upper end of the back board. The side-lying assistance component includes a mounting seat and a rotating block. Clamping plates are slidably arranged at both ends of the mounting seat. The rotating block is slidably connected to the mounting seat, and one end of the rotating block is rotatably connected to the back board.

[0007] Further, the bracket is fixedly installed under the seat board. There are two armrests, which are respectively located on both sides of the wheelchair. The armrests include a telescopic cross bar, a connecting rod, a pulling rod, and a supporting rod. The middle of the connecting rod is rotatably connected to the back board. The connecting rods on both sides of the wheelchair are fixedly connected through the supporting rod. The two ends of the connecting rod are respectively rotatably connected to the telescopic cross bar and the pulling rod. The other end of the telescopic cross bar is rotatably connected to the back board, and the other end of the pulling rod is rotatably connected to the leg board;

[0008] A bottom plate is arranged below the bracket, and a plurality of second electric push rods are fixedly arranged between the bottom plate and the bracket. The height of the seat plate above the bracket is adjusted by the expansion and contraction of the second electric push rods. A plurality of casters are arranged below the bottom plate.

[0009] Furthermore, a first electric push rod is rotatably installed on the bracket. The other end of the first electric push rod is rotatably connected to a support rod. The support rod is driven to move by the expansion and contraction of the first electric push rod, thereby driving the connecting rod to rotate.

[0010] Furthermore, a seat cushion motor is fixedly arranged on the bracket. The rotating shaft of the seat cushion motor is fixedly connected to the seat cushion. The seat cushion is driven to rotate by the seat cushion motor.

[0011] Furthermore, grooves are formed on both sides of the backboard. The support plate is installed in the grooves. One end of the support plate is rotatably connected to the groove, and a sector-shaped folding airbag is arranged in the groove. The lower edge of the sector-shaped folding airbag is fixedly connected to the bottom of the groove, and the upper edge of the sector-shaped folding airbag is rotatably connected to the support plate. Two air pumps are arranged on the bracket. The two air pumps are respectively communicated with the sector-shaped folding airbag through conduits. The sector-shaped folding airbag is inflated and deflated by the air pumps to control the expansion or contraction of the sector-shaped folding airbag, thereby driving the support plate to rotate.

[0012] Furthermore, a first sliding groove and a second sliding groove are formed on the mounting seat. A bidirectional lead screw is rotatably installed in the first sliding groove. Two clamping plates are respectively threadedly sleeved on both ends of the bidirectional lead screw. The two clamping plates are driven to move towards each other or away from each other by rotating the bidirectional lead screw. The rotating block slides along the second sliding groove, and a side body motor is fixedly arranged on the backboard. The rotating block is driven to rotate by the side body motor, driving the mounting seat to rotate.

[0013] Furthermore, a pillow seat is fixedly arranged at the upper end of the backboard.

By rotating a bidirectional lead screw in the mounting seat, the clamping plates move towards each other to clamp the armpits of the patient. The rotating block is driven to rotate by a side body motor on the backboard, driving the mounting seat to rotate, thereby assisting in driving the upper body of the clamped patient to rotate. The air pump on the bracket inflates the fan-shaped folding airbag in one of the grooves, driving the supporting plate to rotate, propping up one side of the patient's back, assisting the patient to turn sideways, and assisting the patient to turn to the side-lying state and maintain it, facilitating echocardiogram examination. When the backboard is in the upright state, the rotation of the mounting seat and the supporting plate can drive the sitting patient to turn sideways. The cushion is rotatably arranged on the seat board. The patient sits on the cushion, and the cushion is driven to rotate by a cushion motor on the bracket, thereby driving the patient's buttocks to rotate towards the side-lying side, enabling the entire upper body of the patient to turn sideways, avoiding the patient's body from being distorted, improving the comfort of the patient's echocardiogram examination, and also facilitating the doctor to use the ultrasonic probe for scanning.
