Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an examination bed for improving the efficiency of examining blood vessels in the lower limbs of patients. Background Art

[0002] In modern healthcare, the diagnosis and treatment of lower extremity vascular diseases are receiving increasing attention. With the accelerated aging of the population and changes in lifestyle, such as prolonged sitting and high-calorie diets, the incidence of lower extremity vascular diseases has shown an upward trend year by year. Common vascular diseases such as lower extremity arteriosclerosis obliterans, deep vein thrombosis, and varicose veins not only seriously affect patients' quality of life but, if not diagnosed and treated promptly, can also lead to serious complications and even be life-threatening. Therefore, accurate and efficient examination of lower extremity vascular conditions is crucial for early detection, precise diagnosis, and effective treatment of diseases.

[0003] In the prior art, in order to facilitate the examination of patients, patients are usually required to take off their lower clothes and then lie on the examination bed for examination. However, patients undergoing vascular examinations are usually not mobile, and the existing examination beds are not convenient for adjusting the height when in use, which makes it very difficult for patients in wheelchairs to get on the bed for examination. Moreover, when the existing examination beds are in use, patients usually need to queue up to wait for examination. After one patient is examined, the patient needs to wait until he or she is dressed before the next patient can be monitored. Some patients are not mobile and are very slow to put on clothes after the examination, which easily increases the waiting time for patients, resulting in a small number of patients who can be examined every day, affecting the efficiency of patient examinations. Summary of the Invention

[0004] The purpose of the present invention is to provide an examination bed that is convenient for improving the efficiency of examining the blood vessels in the patient's lower limbs.

[0030] Usage: When in use, connect the power supply line 48 to the power supply, and then control the bidirectional motor 22 to start as needed through the control console 47 connected by the control line 46. The bidirectional motor 22 drives the driving gear 21 to rotate, and the driving gear 21 drives the driven gear 20 to rotate. The driven gear 20 drives the second driving shaft 19 to rotate, and the second driving shaft 19 drives the driving bevel gear 23 to rotate. The driving bevel gear 23 drives the driven bevel gear 24 to rotate, and the driven bevel gear 24 drives the corresponding threaded rod 25 to rotate. The threaded rod 25 drives the corresponding connecting sleeve 26 to slide relative to the first limiting slide 29, thereby driving the connecting sleeve 26 to move in the direction of approaching or moving away from each other, and drives the first connecting rod 28 to move in the direction of approaching or moving away from each other through the connecting shaft 27, driving the support 18 to slide relative to the U-shaped support rod 17, thereby adjusting the height of the examination bed, making it convenient for the patient to lie on one side of the examination bed for examination.

[0031] The patient's upper body is supported by the lumbar support 30, and the patient's lower body is supported by the first leg support 35 and the second leg support 36. The cotton pad 41 can improve the patient's comfort. The first cylinder 34 can drive the first push rod 32 to move, and the first push rod 32 drives the second connecting rod 33 to move relative to the second limit slide 31, thereby driving the lumbar support 30 to rotate relative to the support 18, and adjusting the angle of the lumbar support 30 to support the patient's upper body. The second cylinder 40 can drive the second push rod 38 to move, and the second push rod 38 drives the third connecting rod 39 to move relative to the third limit slide 37, thereby driving the second leg support 36 to rotate relative to the support 18, and driving the patient's legs to bend and lift, which is convenient for patient examination.

[0032] After a patient is examined, the driving device is started to drive the third worm 12 to rotate, the third worm 12 mobilizes the third worm gear 11 to rotate, the third worm gear 11 drives the first driving shaft 4 to rotate, the first driving shaft 4 drives the first supporting shell 5 to rotate relative to the first worm 7, and the first worm 7 rotates relative to the first supporting shell 5 at the same time, thereby driving the first worm gear 8 to rotate through the first worm 7. When the first driving shaft 4 drives the first supporting shell 5 to rotate, the first supporting shell 5 simultaneously drives the lifting device to rotate, and the lifting device drives the second supporting shell 6 to rotate, thereby driving the patient to rotate with the first driving shaft 4, the first worm gear 8 rotates, driving the second worm 9 to rotate, the second worm 9 drives the second worm gear 101 to rotate, and the second worm gear 101 drives the transmission shaft 10 to rotate, thereby driving the lifting device to rotate with When the first drive shaft 4 rotates, it also rotates relative to the first support shell 5 to ensure that the lifting device is always in a horizontal position, driving the patient to move smoothly to the other side as the first drive shaft 4 rotates. Then the U-shaped bracket 43 is installed in the fixed sleeve 42, and the curtain 44 is pulled. The curtain 44 drives the fixed ring to slide relative to the U-shaped clamp, and a cover is formed by the curtain 44, which makes it convenient for the patient to dress on the other side. At the same time, the next patient is examined here. The third worm 12 and the third worm gear 11 can prevent the patient's own weight from pressing the first drive shaft 4 to rotate. The second worm 9 and the second worm gear 101 can prevent the patient from pressing the lifting device to rotate at will, thereby preventing the patient from falling off the examination bed. The universal wheel 49 at the lower end of the base 1 can facilitate the movement of the examination bed.
