Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an examination bed for obstetrics and gynecology. Background Art

[0002] With advances in medical technology, the demand for greater accuracy and patient comfort in obstetrics and gynecology examinations continues to rise, driving the evolution of examination beds from fixed structures to multifunctional, adjustable ones. Early examination beds provided only simple support for lying down, and position adjustment relied on manual patient handling, which not only increased workload for medical staff but also caused discomfort for patients. In recent years, segmented adjustable beds have emerged, using mechanical or electric drives to adjust the backrest and legrest angles. While this has improved positional adaptability to some extent, significant design flaws remain, making it difficult to meet actual clinical needs. In combination with clinical practice, the existing examination beds have obvious deficiencies in the technical problems addressed by the present invention: The leg rest has a limited range of height and angle adjustment, and the locking is unstable after adjustment, making it difficult to meet the leg support needs of special groups such as pregnant women and obese patients; the surface of the leg rest is mostly hard plastic or ordinary sponge, lacking an arc design that fits the curve of the leg, and long-term support can easily cause numbness in the patient's legs; the anti-slip structure is simple, and it is easy to slip when the patient's body position changes, posing a safety hazard. The lighting device is fixed in position or has a limited adjustment range, making it difficult to accurately focus on the examination area; there is a lack of integrated disinfection components, so doctors need to frequently use external disinfection tools, interrupting the operation process. The excrement collection structure has poor sealing and is prone to leakage; disposable consumables are cumbersome to install and not firmly fixed, which increases the workload of medical staff. It is unable to meet diverse demands such as lighting, image acquisition, and disinfection at the same time, and requires the use of multiple additional devices, which takes up diagnosis and treatment space. The above problems result in low efficiency and poor patient experience in clinical use of existing examination beds, as well as the risk of cross-infection. Therefore, there is an urgent need for an obstetrics and gynecology examination bed that is optimized in terms of posture adjustment, comfort, ease of operation, sanitary protection and functional integration to solve the above technical problems.
