It is an auxiliary medical equipment for hospitals, clinics, family planning stations and mobile gynecological examination vehicles to conduct various gynecological examinations, diagnostic operations, etc. This series of products can adjust the various body positions of patients according to actual conditions.

[0003] For example, the Chinese utility model patent with application number CN201920692836.0 discloses a gynecological examination bed, which includes a bed body, a leg support device, a retractable bed ladder and a waste disposal box. The leg support device is provided with two, and the two leg support devices are symmetrically connected to the rear end of the bed body, the retractable bed ladder is connected to the lower end of the bed body, and the waste disposal box is connected to the lower rear end of the bed body. The utility model provides a gynecological examination bed, which can adjust the height of the patient's leg support and arbitrarily change the angle of the leg opening through the use of the bed body and the leg support device, so as to facilitate the doctor's examination. The retractable bed ladder can assist patients with limited mobility to get on the bed, and can be retracted when not in use, saving space while not affecting the doctor's close examination of the patient. The waste disposal box can be used to collect the waste generated by the doctor applying medicine or flushing the patient, so as to avoid destroying the clean environment of the gynecological examination. However, there are still some shortcomings, as described below: The examination bed used in the prior art needs to use a bed board to support the buttocks of the human body to ensure the stability of the human body after the lithotomy position is formed; however, with such a structural setting, the bed board will block a part of the skin of the human buttocks, thereby hindering the examination operation; on the other hand, during the lithotomy position examination, when it is necessary to flush the patient's vagina and vulva, the flushing liquid easily flows along the patient's body to the bed board, causing the bed board to be contaminated by the cleaning liquid, increasing the workload of medical staff in cleaning the treatment bed.

[0004] Therefore, under the premise that the examination bed board does not support the patient's buttocks, how to ensure the stability of the patient in the lithotomy position is a technical problem that needs to be solved urgently in the prior art. Summary of the invention

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The foot-operated lifting gynecological examination bed of the present invention, which is suitable for patients with limited mobility and utilizes the principle of a lever, uses the restraining component to fix the patient's torso on the bed board. After the patient forms a lithotomy position, the patient's buttocks can be outside the support range of the bed board, thereby preventing the flushing liquid from flowing onto the bed board and causing contamination when the vagina and vulva are flushed, effectively reducing the workload of medical staff in cleaning the examination bed and improving the practicability of the present invention in actual use. Furthermore, in the present embodiment, after the patient stands with his back against the surface of the bed board, the restraining component is used to tie the patient's waist, and then the bed board and the bed frame are adjusted from the first matching state to the second matching state. During this process, the patient's torso is gradually supported by the bed board, so that the patient completes the action of lying on the examination bed. Compared with the prior art method that requires patients to lie on the examination bed by themselves, the present invention improves the convenience of patients with inconvenient legs and feet lying on the examination bed; at the same time, in this embodiment, the patient can adjust the position of lying on the bed board in a standing state, avoiding the patient to move the body to adjust the body position on the examination bed, thereby further improving the practicality of the present invention in actual use; further, adopting this structural setting, during the process of the patient lying on the examination bed and leaving the examination bed after the examination, the patient's buttocks can be completely avoided from contacting the bed board, thus effectively reducing the degree of contamination of the examination bed after use, thereby further reducing the workload of medical staff in cleaning the examination bed; 2. The foot-operated lifting gynecological examination bed for patients with limited mobility using the lever principle described in the present invention is provided with the slide groove, the locking component and the fixing seat being matched. In actual use, when the patient lies on the treatment bed of the present invention to form a lithotomy position, the locking component is separated from the fixing seat, and the fixing seat slides along the slide groove under the action of the patient's own weight, thereby eliminating the matching gap formed between the patient's thigh part and the second loading plate, and the leg support frame can form a more stable support for the patient's legs, effectively offsetting the force exerted by the patient's body weight on the restraining component, thereby reducing the squeezing force of the restraining component on the patient's waist, further improving the patient's comfort during examination and treatment; at the same time, the force exerted by the patient's body weight on the restraining component is reduced, and the deformation of the fixed airbag can be correspondingly reduced, thereby reducing the risk of rupture and damage of the fixed airbag during use, thereby further improving the practicality and reliability of the present invention in actual use; 3. The foot-operated lifting gynecological examination bed for patients with limited mobility using the lever principle described in the present invention has the slide groove tilted. When the fixed seat slides along the slide groove beyond the second end of the bed board, the sliding plate can gradually move away from the supporting plane of the bed board, so that a gap is formed between the sliding plate and the bed board. In this way, under the condition of the same sliding distance, the displacement of the patient's buttocks to the side of the bottom of the examination bed can be reduced, which is more conducive to the full exposure of the patient's examination part, and further improves the practicality of the present invention in actual use; on the other hand, with this structural setting, the limiting ring plate is gradually reduced from the side close to the second end of the bed board to the side away from the second end of the bed board, and the accommodation space formed between the limiting ring plate and the bed board is shaped to be more compatible with the shape of the protrusion of the human abdomen, and the fixed airbag can more fully cover the patient's waist, thereby improving the stability of the restraining component in fixing the patient's body; Furthermore, a rotating shaft is provided between the sliding plate and the fixed seat, and the sliding plate can rotate around the rotating shaft; when the locking component is connected to the fixed seat, the rotating shaft is located on the side of the sliding groove away from the second end of the bed board, and when the fixed seat slides to the end of the sliding groove close to the second end of the bed board, the rotating shaft is located within the supporting plane of the bed board. When the fixing seat slides along the sliding groove beyond the second end of the bed board and a gap is formed between the sliding plate and the bed board, the patient's torso will press the end of the sliding plate away from the second end of the bed board. Under the action of the pressing force, the sliding plate rotates around the rotating axis, so that the end of the sliding plate away from the second end of the bed board can fit with the bed board, thereby reducing the height of the step formed between the sliding plate and the bed board, and improving the comfort of the patient during examination and treatment; on the other hand, after the sliding plate rotates, the end of the sliding plate close to the second end of the bed board can be tilted upward, which can compress the accommodation space formed between the limiting ring plate on the side of the second end of the bed board and the bed board, so as to fill the contraction of the patient's abdomen when the patient lies on the treatment bed to form a lithotomy position, thereby further improving the stability of the restraining component in fixing the patient's body; on the other hand, the end of the sliding plate close to the second end of the bed board is tilted upward, which can further reduce the displacement of the patient's buttocks to the bottom side of the examination bed, thereby being more conducive to the full exposure of the patient's examination part.

On the basis of the above scheme, further, a sliding plate 19 is connected to the fixed seat 16, and the width of the sliding plate 19 matches the width of the limiting ring plate 17. The sliding plate 19 fits the surface of the bed board 2, and a slide groove 20 is provided on the side of the bed board 2. A gap is provided between the slide groove 20 and the second end of the bed board 2. The fixed seat 16 is clamped in the slide groove 20. A locking component 21 is further provided on the bed board 2. The locking component 21 is detachably connected to the fixed seat 16. When a human body lies flat on the bed board 2, the bed board 2 and the bed frame 1 are adjusted to form a second matching state, and the locking component 21 is separated from the fixed seat 16. Under the action of gravity, the fixed seat 16 can slide along the slide groove 20 so that the end of the limiting ring plate 17 exceeds the second end of the bed board 2.

[0041] Specifically, in this embodiment, it is taken into account that different patients have different body shapes. After some patients lie on the treatment bed of the present invention to form a stone position, their thighs may not fit tightly with the second loading board 15. Furthermore, since the first end of the bed board 2 is higher than the second end when the bed board 2 and the bed frame 1 form a second matching state, the body of the patient will tend to slide down after lying on the bed board 2 in the lithotomy position, which causes the weight of the patient's body to be concentrated on the restraining component 3. On the one hand, the squeezing force applied by the restraining component 3 on the patient's waist will increase, affecting the patient's comfort during examination and treatment. On the other hand, the patient's body weight is concentrated on the restraining component 3, which will also aggravate the deformation of the fixed airbag 18 and increase the risk of rupture and damage of the fixed airbag 18 during use. On the other hand, when the patient forms a lithotomy position, the thigh of the patient does not fit tightly with the second loading board 15, which will increase the burden on the calf, thereby further reducing the patient's comfort during examination and treatment. Based on the above reasons, the slide groove 20 and the locking component 21 are arranged in cooperation with the fixing seat 16 in the present embodiment. In actual use, after the patient lies on the treatment bed of the present invention to form a lithotomy position, the locking component 21 is separated from the fixing seat 16, and the fixing seat 16 slides along the slide groove 20 under the action of the patient's own weight, thereby eliminating the matching gap formed between the patient's thigh area and the second loading plate 15, and the leg support 4 can form a more stable support for the patient's legs, effectively offsetting the force exerted by the patient's body weight on the restraining component 3, thereby reducing the squeezing force of the restraining component 3 on the patient's waist, and further improving the patient's comfort during examination and treatment; at the same time, the force exerted by the patient's body weight on the restraining component 3 is reduced, and the deformation of the fixed airbag 18 can also be reduced accordingly, thereby reducing the risk of rupture and damage of the fixed airbag 18 during use, thereby further improving the practicality and reliability of the present invention in actual use.

[0042] In this embodiment, the locking component 21 includes a fixing pin hole and a fixing pin shaft. The fixing pin hole is arranged on the fixing seat 16. When the fixing pin shaft is inserted into the fixing pin hole, the fixing seat 16 is locked, and the fixing seat 16 forms a fixed fit with the slide groove 20; when the fixing pin shaft is pulled out of the fixing pin hole, the fixing seat 16 can slide along the slide groove 20.

[0043] Example 5: Figures 3 to 7As shown, the present invention describes a foot-operated lifting gynecological examination bed that utilizes the lever principle and is suitable for patients with limited mobility. On the basis of the above scheme, further, the slide groove 20 is arranged at an angle, and the vertical distance between the end of the slide groove 20 close to the second end of the bed board 2 and the supporting plane of the bed board 2 is smaller than the vertical distance between the end of the slide groove 20 away from the second end of the bed board 2 and the supporting plane of the bed board 2.

[0044] In this embodiment, the slide groove 20 is tilted. When the fixed seat 16 slides along the slide groove 20 beyond the second end of the bed board 2, the sliding plate 19 can gradually move away from the supporting plane of the bed board 2, so that a gap is formed between the sliding plate 19 and the bed board 2. In this way, under the condition of the same sliding distance, the displacement of the patient's buttocks to the side of the bottom of the examination bed can be reduced, which is more conducive to the full exposure of the patient's examination part, and further improves the practicality of the present invention in actual use; on the other hand, with this structural setting, the limiting ring plate 17 is moved from the side close to the second end of the bed board 2 to the side away from the second end of the bed board 2, and the accommodating space formed between the limiting ring plate 17 and the bed board 2 is gradually reduced. The shape of the accommodating space formed between the limiting ring plate 17 and the bed board 2 can be more matched with the shape of the bulge of the human abdomen, and the fixed airbag 18 can more fully cover the patient's waist, thereby improving the stability of the restraining component 3 in fixing the patient's body.

[0045] As a preferred embodiment, on the basis of the above scheme, further, a rotating shaft 22 is provided between the sliding plate 19 and the fixed seat 16, and the sliding plate 19 can rotate around the rotating shaft 22; when the locking component 21 is connected to the fixed seat 16, the rotating shaft 22 is located on the side of the slide groove 20 away from the second end of the bed board 2, and when the fixed seat 16 slides to the end of the slide groove 20 close to the second end of the bed board 2, the rotating shaft 22 is located within the support plane of the bed board 2.

[0046] Specifically, in this embodiment, when the fixing seat 16 slides along the sliding groove 20 beyond the second end of the bed board 2 and a gap is formed between the sliding plate 19 and the bed board 2, the patient's torso will press the end of the sliding plate 19 away from the second end of the bed board 2. Under the action of the pressing force, the sliding plate 19 rotates around the rotating shaft 22, so that the end of the sliding plate 19 away from the second end of the bed board 2 can fit with the bed board 2, thereby reducing the height of the step formed between the sliding plate 19 and the bed board 2, thereby improving the comfort of the patient during examination and treatment. On the other hand, After the sliding plate 19 rotates, one end of the sliding plate 19 close to the second end of the bed board 2 can be tilted upward, which can compress the accommodating space formed between the limiting ring plate 17 and the bed board 2 on the side of the second end of the bed board 2, so as to fill the contraction of the patient's abdomen when the patient lies on the treatment bed to form a lithotomy position, thereby further improving the stability of the restraining component 3 in fixing the patient's body; on the other hand, the sliding plate 19 close to the second end of the bed board 2 is tilted upward, which can further reduce the displacement of the patient's buttocks to the bottom side of the examination bed, thereby being more conducive to fully exposing the patient's examination area.

[0047] It should be noted that in this embodiment, when the patient lies on the treatment bed to form a lithotomy position, most of the weight of his or her body trunk will be concentrated in the area where the waist and the backboard meet. The compressive force applied by the body trunk can effectively act on the end of the sliding plate 19 away from the second end of the bed board 2, ensuring that the sliding plate 19 rotates.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
