[0002] B-ultrasound examination has an irreplaceable position in the clinical diagnosis of diseases. B-ultrasound examination usually requires the patient to lie down to facilitate the doctor's examination. Some special examinations, such as transvaginal color ultrasound, require the patient to take the lithotomy position with legs raised and spread apart for examination. This requires the installation of leg rests on both sides of the traditional B-ultrasound examination bed. The installation, disassembly and subsequent storage of the leg rests need to be completed in the examination room. B-ultrasound equipment usually has more lines and occupies a large area, which increases the difficulty of functional conversion of the B-ultrasound bed. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] Specific implementation examples Figure 1 and Figure 2 As shown, the present invention is a B-ultrasound multi-posture examination bed, comprising a bed frame 1 and a leg support assembly arranged at the tail of the bed frame 1, the bed frame 1 is provided with a fixed bed board 2 and a folding bed board 3, the fixed bed board 2 is fixedly connected to the front part of the bed frame 1, the folding bed board 3 is hinged at the tail of the bed frame 1, the leg support assembly is arranged below the folding bed board 3 by means of a swing mechanism, the swing mechanism comprises a fixed arm 4, a rotating seat 5 and a swing rod assembly, the fixed arm 4 is fixedly connected to the tail of the bed frame 1, the overhanging end of the fixed arm 4 is hinged to the rotating seat 5 to form a rotating shaft 6, the swing rod assembly comprises a first swing rod 7, a second swing rod 8 and a leg support plate 9, the first swing rod 7 and the second swing rod 8 are hinged between the leg support plate 9 and the rotating seat 5 to form a four-bar linkage, the second swing rod 8 is also connected to a driving telescopic cylinder 10 for driving it to swing, and the leg support plate 9 has the freedom of movement to be lifted to the plane where the fixed bed board 2 is located by the swing of the first swing rod 7 and the second swing rod 8.

[0020] The present invention adopts a swing mechanism to set the leg support assembly on the bed frame 1 and hide it under the bed board. When in use, the leg support can be raised by driving the telescopic cylinder 10 to push it out, avoiding the installation and disassembly of the leg support, and also facilitating later storage. At the same time, it can conveniently convert the form of the examination bed to facilitate multi-posture examination of patients. Specifically, when in use, the present invention extends the telescopic cylinder 10 to make the second swing rod 8 connected to the telescopic cylinder 10 swing counterclockwise, such as Figure 2 As shown, by means of the four-bar linkage formed by the first swing rod 7, the second swing rod 8, the leg support plate 9 and the rotating seat 5, the leg support plate 9 forms an upward swinging motion, and finally as shown in FIG. Figure 2 As shown in the figure, the leg support assembly is lifted onto the bed board for the patient to place his legs to form a lithotomy position. The driving telescopic cylinder 10 is an electric push rod, and the different lengths of the electric push rod can make the leg support assembly lift to different heights, thereby adapting to the examination needs of different patients.

[0021] The height of the leg support plate 9 can be controlled and adjusted by means of an electric push rod. If it is adjusted higher, it can be used for gynecological vaginal ultrasound examination. If it is adjusted slightly lower, the legs can be slightly raised so that the legs are a little away from the bed surface. Some patients with leg fractures find it difficult to move independently when examining the large blood vessels in the legs. The present invention can facilitate the examination of the leg blood vessels.

[0022] Further, such as Figure 1 and Figure 2 As shown, a raised first extension rod 11 is fixedly provided on the second swing arm 8, a second extension rod 12 is hingedly provided on the rotating seat 5, an intermediate rod 13 is hinged between the free ends of the first extension rod 11 and the second extension rod 12, and the free end of the second extension rod 12 is also hinged to the telescopic end of the driving telescopic cylinder 10, and the telescopic end of the driving telescopic cylinder 10 pushes the second swing arm 8 to produce a swinging motion with the help of the intermediate rod 13.

[0023] With the help of the intermediate rod 13, the first extension rod 11 and the second extension rod 12, the installation position of the driving telescopic cylinder 10 is placed horizontally below the rotating seat 5, so that the larger driving telescopic cylinder 10 can be installed below the relatively low bed frame 1, saving installation space. At the same time, the driving telescopic cylinder 10 and the leg support assembly are respectively located on both sides of the rotating shaft 6, which balances the force on the rotating shaft 6 and prolongs the service life.

[0024] Furthermore, a limit plate 14 is provided on the rotating seat 5, and a limit bolt 15 is threadedly connected to the limit plate 14. A limit seat 16 is provided at the lower end of the fixed arm 4, and the end of the limit bolt 15 abuts against the limit seat 16 of the fixed arm 4 to form a limit fit.

[0025] After the limit bolt 15 is unscrewed, the staff can manually push the rotating seat 5 away, so that the leg support assembly on the rotating seat 5 swings outwards. Figure 3 As shown, after adjusting to the desired angle, the limiting bolt 15 is screwed so that the end of the limiting bolt 15 abuts against the limiting seat 16 to form a limit position, thereby preventing displacement during use by the patient.

[0026] Furthermore, a rubber sheet 17 is provided on the upper end surface of the leg support plate 9, the middle part of the rubber sheet 17 is fixedly connected to the leg support plate 9, and a lifting rod 18 extending beyond the hinge point is provided at the end of the first swing arm 7, and the lifting rod 18 is located below both sides of the rubber sheet 17. When the first swing arm 7 is swung up, the lifting rod 18 lifts both sides of the rubber sheet 17 to form a groove-like structure that can accommodate the legs.

[0027] When the leg support plate 9 is raised by the first swing rod 7 and the second swing rod 8, the two sides of the rubber sheet 17 are lifted by the lifting rod 18, so as to form a leg-placement groove to prevent the patient's legs from falling during the examination and avoid accidents.

[0028] Furthermore, the folding bed board 3 includes a main folding board 19 and auxiliary folding boards 20 arranged on both sides of the main folding board 19. The main folding board 19 is hingedly connected to the tail of the bed frame 1, and the auxiliary folding boards 20 are hingedly connected to both sides of the main folding board 19 and have the freedom to swing to one side of the upper board surface of the main folding board 19.

[0029] The folding bed board 3 is provided as Figure 4 As shown, it can be folded down to make room for the doctor to operate. Figure 4 For the sake of convenience in display, the leg support assembly on the shielding side of the two symmetrically arranged leg support assemblies is hidden, and the auxiliary folding plate 20 is arranged as shown in FIG. Figure 3 As shown, it can be folded onto the main folding plate 19, so as to reduce the space occupied by the folding bed board 3 when the main folding plate 19 is lowered. At the same time, with the help of the setting of the auxiliary folding plate 20, the leg support plate 9 can be raised without lowering the main folding plate 19 and swinging outward with the help of the rotating shaft 6, thereby improving the flexibility of use.

[0030] Further, such as Figure 3 and Figure 4 As shown, a support plate 21 is hingedly provided on the rotating seat 5. The support plate 21 is hinged to the rotating seat 5 in the vertical direction and has the freedom of rotation to swing to below the main folding plate 19 and the auxiliary folding plate 20. The folding bed board 3 is supported flush with the fixed bed board 2 by the support plate 21.

[0031] With the aid of the support sheet 21, the main folding plate 19 and the auxiliary folding plate 20 can be supported, thereby retaining the function of the examination bed as a traditional lying posture examination device.

[0032] As a further improvement of the present invention, a neck pillow 22 driven by an electric push rod is also provided on the side of the fixed bed board 2 located at the patient's head. When the neck blood vessels are examined, the neck pillow 22 rises and presses against the neck, so that the neck is slightly raised, so that the head is tilted back, and it is convenient for doctors to examine the neck blood vessels and obtain clearer images. When it is not needed, the neck pillow 22 can be retracted by the electric push rod, so that the neck pillow 22 is lowered to the same height as the fixed bed board 2.

[0033] Side lying boards 23 are hinged on the left and right sides of the fixed bed board 2 respectively. The side lying boards 23 have the freedom to swing relative to the fixed bed board 2 by means of their hinge axes. Medical staff can lift the side lying boards 23 to facilitate the patient to switch between lying flat, left side lying position or right side lying position for cardiac ultrasound examination.
