Auxiliary supporting device for inspection

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to an auxiliary supporting device for examination.

Background

The modern medicine is divided into various different diagnosis and treatment departments such as internal medicine, surgery, obstetrics and gynecology department, pediatrics and five sense organs, the human body parts and examination modes related to the internal parts of the different medical diagnosis and treatment departments are different, and the medicine has pertinence, wherein gynecology is mainly used for analyzing, diagnosing and preventing various etiologies and pathologies of female genital organ diseases in medicine, and plays a vital role in guaranteeing the body health of women.

In the diagnosis and treatment process of obstetrics and gynecology, a professional gynecological examination table is usually required, a patient needs to lie on the examination table before examination, two legs are diverged, and the patient is placed in a special leg support concave leg support on the examination table so as to keep a lithotomy position. The interval that the two legs of the patient of different body types are separated is different, for example, the patient of the slim body type and the big body type is because the size of crotch is different, leads to the interval difference of the two legs on crotch both sides from this, and then makes the interval that the two legs of different patients normally degree are separated various. However, in the gynecological examination table used today, the concave leg rest on the leg rest can only be adjusted in a limited rotation manner by the limitation of the universal rotary joint below the concave leg rest, the requirements of patients with different body types are difficult to adapt to, the leg lengths of the patients are various, and the distance between the different patients with different leg lengths and the requirements of the concave leg rest on the leg rest are different. During the long-time diagnosis and treatment process of a patient, the examination bed possibly has a slightly forward inclined angle due to the examination requirement, the patient is likely to gradually slide down due to the gravity action, and the patient can often tighten the body to resist the sliding, so that the diagnosis and treatment of medical staff can be hindered. After a patient is subjected to a long-time diagnosis and treatment process, the problem that the patient is difficult to get up is caused by numbness of lower limbs, and the existing gynecological examination table lacks an impetus which can be provided for the patient to assist in getting up.

The utility model provides an auxiliary device for gynaecology's inspection bed as proposed in the patent document of publication No. CN211723828U among the prior art, including first baffle, the gyro wheel, right X type support frame, left X type support frame, the brake lever, brake bolt, second baffle and support leg support, first baffle bottom is equipped with the gyro wheel, right X type support frame one end and first baffle upper surface right side swing joint, and be equipped with brake bolt on the right X type support frame, right X type support frame other end and second baffle bottom right side swing joint, left X type support frame and right X type support frame become to set up in first baffle upper surface left side in pairs, and be equipped with brake bolt on the left X type support frame, left X type support frame other end and second baffle bottom left side swing joint, the left and right both ends of brake lever alternate respectively and set up inside the brake bolt on left X type support frame and right X type support frame. Although the problem of patient's shank travelling comfort has been solved to this patent, still there is the easy landing of position in the patient's inspection process, the difficult problem of getting up after the inspection is accomplished.

The utility model discloses a make things convenient for gynaecology's inspection bed of leg and foot support like publication number CN108210226A among the prior art, including the bed body, ground slide rail assembly, foot supporting mechanism and two shank supporting mechanism, the bed body is including fixed bed board and movable bed board, the bottom surface of fixed bed board is provided with the footpost, ground slide rail assembly sets up in movable bed board one side, ground slide rail assembly includes fixed slide rail, two connecting rods and two removal slide rails, fixed slide rail includes main track and side rail, the main track passes through two connecting rods and is connected with the footpost of movable bed board one side, two shank supporting mechanism sliding connection is on the main track, foot supporting mechanism sliding connection is on two removal slide rails, the one end of two removal slide rails all is provided with the slider, slider sliding connection is on the side rail. Although the problem of patient's shank travelling comfort has been solved to this patent, there is the external ground subassembly space that is used for supporting patient's shank and foot to occupy comparatively huge, easily causes inconvenient problem in the in-service use.

In the prior art, as disclosed in patent document with publication number of CN213284066U, an anti-skid obstetric examination bed comprises a base, a foot plate and a back plate, wherein a supporting mechanism is movably arranged on the back plate, the supporting mechanism comprises a chute, a guide post with a vertical horizontal line is arranged on the inner side of the chute, a sliding block capable of sliding along the guide post is arranged on the guide post, a foam cushion is arranged at the top of the sliding block, a limit bolt for limiting the sliding block is arranged on the side wall of the sliding block, and a buttock silica gel pad is arranged at the joint of the back plate and the base; through utilizing the slider to support patient's creak nest department, buttock silica gel pad supports patient's buttock, and the height-adjustable of slider is convenient for support the patient of different statures. Although the problem of easy landing in the patient's inspection process has been solved to this patent, but the interval of slider on the width is unadjustable, does not consider the different fat thin patient to the requirement of slider interval different, and the effort of slider is too concentrated in patient's creak nest department, and the time is long also can bring painful sense for the patient.
