Description

Technical Field

[0001] The invention relates to the technical field of beds, and more particularly to an auxiliary frame for hysterosalpingography. Background Art

[0002] Hysterosalpingography is an examination in which a catheter is inserted into the uterine cavity through the vagina and cervix, a water-soluble contrast agent is injected, and dynamic observation and filming are performed under a gastrointestinal angiography machine to observe the morphology of the uterine cavity and whether the fallopian tubes are blocked, the location and degree of blockage, and the diffusion of the contrast agent in the pelvic cavity.

[0003] When performing a hysterosalpingography examination, the patient is required to lie on his back on the auxiliary frame and assume the lithotomy position so that the female patient's genitals can be exposed to the maximum extent, so that the required uterine cavity tube can be inserted into the female patient's uterine cavity, and then the contrast agent is injected into the female patient's uterine cavity through the corresponding uterine cavity tube. The existing auxiliary frame is not equipped with a knee support, and the patient's legs can only support themselves at the bedside. For patients with a long examination time or weak constitution, this long-term self-support may cause great discomfort and even physical exhaustion. Patients who require painless hysterosalpingography examinations are also required to lift their legs and assume the lithotomy position, so some patients may not be able to undergo catheterization.

[0004] The auxiliary frame used for hysterosalpingography generally includes a bed body and lithotomy leg supports symmetrically arranged at the middle and rear parts of both sides of the corresponding bed body. There are existing technologies for gynecological auxiliary frames with this structure, but the auxiliary frame with this structure is only suitable for uterine cavity catheterization of patients in lithotomy position, but not suitable for hysterosalpingography of patients lying flat, because the leg supports may block or interfere with hysterosalpingography. Therefore, after catheterization, the patient needs to be moved to another auxiliary frame for hysterosalpingography. During the movement, not only will the patient's pain increase, but the placed uterine cavity catheter will also be at risk of falling out. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an auxiliary frame for hysterosalpingography, wherein a fixing plate is installed on an examination bed by bolts, and the top surface of the fixing plate is flush with the bed surface of the examination bed; when a uterine cavity catheter is placed before a hysterosalpingography examination, since the fixing plate is installed at the rear of the examination bed, the patient can lie flat on the auxiliary frame above the waist during the examination, and the leg frame holds up the legs, and the patient is placed in a lithotomy position; when a hysterosalpingography examination is performed, the leg brackets can be stored on both sides of the fixing plate so that the top surface of the leg brackets is not higher than the fixing plate, and when the patient lies completely flat, the legs will not form any unnecessary bulges or obstacles due to the presence of the leg brackets, thereby effectively avoiding any influence that may be caused to the examination of the patient's uterine area.

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.

[0021] The inventors have carefully analyzed the disadvantage of the auxiliary frame in the prior art that the placed uterine tube may be at risk of falling out. The main reason for the above technical problem is that the auxiliary frame of this structure is only suitable for placing a uterine tube in the patient's lithotomy position, but not suitable for the patient to lie flat for hysterosalpingography. The leg support may block or interfere with the hysterosalpingography. Therefore, after the tube is placed, the patient needs to be moved to another auxiliary frame for angiography. During the movement, not only will the patient's pain increase, but the placed uterine tube may also be at risk of falling out.

[0022] Embodiment 1:

[0023] like Figures 1 to 3As shown, an auxiliary frame for hysterosalpingography includes two frame assemblies, which are symmetrically installed on both sides of an examination bed 2. The frame assemblies are composed of a fixed plate 1 and a leg bracket 3 installed on the fixed plate 1. The fixed plate 1 is connected to the examination bed 2 by bolts; the leg bracket 3 is erected at the rear ends of both sides of the fixed plate 1 and is used to support the patient's legs, so as to facilitate the patient to assume the lithotomy position.

[0024] The leg support 3 includes a bracket 31 and a leg-shaped jacket 32. One side of the bracket 31 is connected to the leg-shaped jacket 32, and the other side is rotatably mounted on the fixed plate 1. The leg-shaped jacket 32 ​​is L-shaped as a whole and has a groove for placing the leg joint, and the angle between the two surfaces is 120 degrees to 150 degrees. The leg-shaped jacket 32 ​​is a groove-shaped imitation of the shape of the leg, and the whole simulates the L-shape of the bent leg joint, and the angle between the two surfaces is between 120 degrees and 150 degrees, which improves the comfort of the patient.

At the same time, the angle that the rotating rod 33 can be rotated is converted into the sliding distance of the slider 5 for adjustment, and it is easier to adjust the height of the leg bracket 3. The connecting rod 37 also forms a triangular support with the rotating rod 33, strengthens the structural strength of the leg bracket 3, avoids the use of the rotating rod 33 as a cantilever beam, and the leg bracket 3 is not easy to bend and deform in the process of supporting the leg. The leg-shaped jacket 32 ​​can swing relative to the rotating rod 33. By rotating the rotating rod 33, the patient's legs can still be placed in the leg-shaped jacket 32, and the angle of placement of the legs can be adjusted, which not only enables the leg support 3 to support the legs, but also improves the patient's comfort.

[0026] Among them, a limiting device 4 is provided at the bottom of the mounting seat 35, which includes a screw 41, a pressure block and a handle 42 respectively provided at both ends of the screw 41, the screw 41 is inserted into the ball groove of the mounting seat 35 and is threadedly connected with the mounting seat 35, the pressure block is located in the ball groove of the mounting seat 35, and the handle 42 is used to press the pressure block against the ball head 36 after rotating the screw 41.
