Foldable inflatable support pad for patient positioning in the operating room

Abstract

This utility model provides a foldable inflatable support pad for patient positioning in the operating room, relating to the field of medical device technology. It includes: a lower support plate, a rotating connecting plate hinged to the rear of the lower support plate, and an upper support plate hinged to the rotating connecting plate. The upper support plate folds over and covers the lower support plate, and has a curved structure. An inflatable air cushion is glued to the top of the upper support plate, and a support air bladder is fixedly connected to the bottom of the upper support plate. The bottom surface of the support air bladder is attached to the upper surface of the lower support plate. By inflating the air cushion, its elasticity and hardness can be controlled to provide suitable support hardness for the patient. The grooved design of the bottom support plate allows the inflatable air cushion to bend and deform downwards during leg support, providing a suitable arc-shaped fit and positioning fixation for the legs. This solves the problems of not being able to adapt to the required height, the lack of adjustable support pad hardness, and deformation under leg weight, leading to increased pressure on the legs and reduced blood circulation.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a foldable inflatable support pad for fixing the position of patients in the operating room. Background Technology

[0002] During lower limb surgery, support pads are needed to stably elevate and support the legs, thereby fully exposing the surgical field, maintaining an ideal surgical position, and effectively preventing local tissue compression. This operation helps doctors perform surgical procedures more precisely, while also promoting blood return in the lower limbs, reducing swelling, and lowering the risk of accidental neurovascular injury. It is an important step in ensuring the safety and success of the surgery.

[0003] Traditional lower limb support pads are filled with sponge or silicone, which have some elasticity but lack height adjustment. They cannot be adjusted to suit the needs of different patients, and the hardness of the support pad is not adjustable. Under the weight of the legs, the pad is squeezed and deformed, which increases the pressure on the legs and reduces the blood circulation in the legs. Utility Model Content

[0004] This utility model provides a foldable inflatable support pad for patient positioning in the operating room, which solves the problem that traditional lower limb support pads are filled with sponge or silicone, which have a certain degree of elasticity but lack height adjustment function. They cannot be adapted to different patients according to their required height, and the hardness of the support pad cannot be adjusted. Under the weight of the legs, the pad is squeezed and deformed, which increases the pressure on the legs and reduces the blood circulation in the legs.

[0005] This utility model provides a foldable inflatable support pad for patient positioning in the operating room, specifically including: a lower support plate, a rotating connecting plate hinged to the rear of the lower support plate, an upper support plate hinged to the rotating connecting plate, the upper support plate being folded over and covering the lower support plate, the upper support plate having a curved structure, an inflatable air cushion glued to the top of the upper support plate, a support airbag fixedly connected to the bottom of the upper support plate, the bottom surface of the support airbag being attached to the upper surface of the lower support plate, two inner reinforcing airbags and an outer airbag fixedly connected to the bottom of the upper support plate, the lower surfaces of the inner reinforcing airbags and the outer airbags being attached to the upper surface of the lower support plate, and a support plate through groove opened in the center of the upper support plate.

[0006] Furthermore, an air pump is fixedly connected to the center of the upper surface of the lower support plate, and the air pump is connected to a control panel via an electrical connection line. The control panel is fixedly connected to the front edge of the upper surface of the lower support plate, and the upper support plate has support plate sides on both sides.

[0007] Furthermore, the air outlet of the inflation pump is fixedly connected to a diversion air supply pipe, the diversion air supply pipe is connected to the support airbag through a flexible hose, and a support air valve is installed on the connecting pipe between the support airbag and the diversion air supply pipe. The support air valve is connected to the control panel, the inflatable air cushion, the inner reinforcing airbag and the outer airbag through an electrical connection wire.

[0008] Furthermore, an inflatable air cushion is connected to the top of the gas diversion pipe via a flexible hose. An air cushion valve is installed on the connection between the inflatable air cushion and the gas diversion pipe. The air cushion valve is connected to the control panel via an electrical connection wire.

[0009] Furthermore, the inner reinforcing airbag is connected to the shunt air supply pipe via a hose, and an inner air valve is installed on the connecting pipe between the inner reinforcing airbag and the shunt air supply pipe. The outer airbag is connected to the shunt air supply pipe via a hose, and an outer air valve is installed on the connecting pipe between the outer airbag and the shunt air supply pipe.

[0010] Furthermore, the outer airbag is located in front of the inner reinforcing airbag, and both the inner and outer air valves are connected to the control panel via electrical connection lines.

[0011] This utility model provides a foldable inflatable support pad for patient positioning in the operating room, which has the following beneficial effects: In this utility model, the surgical positioning support pad uses an inflatable air cushion to support the patient's legs and provide stable support. By inflating the air cushion, the elasticity and hardness of the air cushion can be controlled to provide the patient with appropriate support hardness. Through the setting of the groove in the bottom support plate, the air cushion bends and deforms downward during the process of supporting the legs, providing a suitable arc fit and positioning fixation for the legs.

[0012] In addition, the main body of the support pad is formed by hinged connection between the lower support plate and the upper support plate. Support airbags, inner reinforcing airbags, and outer airbags are placed inside the lower and upper support plates to maintain the shape and angle of the support pad and give it a certain degree of elasticity. The support angle can be adjusted by inflating the airbags with an air pump to increase the air pressure inside the airbags, thereby increasing the support strength of the airbags on the upper support plate and thus increasing the tilt angle of the upper support plate and changing the support angle of the support pad. Through the cooperation of multiple airbags distributed in different positions, the elasticity of the support pad can be controlled by selecting the number of inflatable airbags, thereby improving comfort.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a foldable inflatable support pad for patient positioning in the operating room, comprising: a lower support plate 1, a rotating connecting plate 101 hinged to the rear of the lower support plate 1, an upper support plate 2 hinged to the rotating connecting plate 101, the upper support plate 2 folding over and covering the lower support plate 1, the upper support plate 2 having a curved structure, an inflatable air cushion 4 glued to the top of the upper support plate 2, a support airbag 3 fixedly connected to the bottom of the upper support plate 2, the bottom surface of the support airbag 3 adhering to the upper surface of the lower support plate 1, and two inner reinforcing airbags 5 and an outer airbag 6 fixedly connected to the bottom of the upper support plate 2. The lower support plate 1 is attached to the upper surface of the upper support plate 2. The upper support plate 2 has a support plate through groove 202 in the center and support plate side edges 201 on both sides, which limit the inflatable air cushion 4. The upper support plate 2 is supported between the lower support plate 1 and the upper support plate 2 by the support air 3, the inner reinforcing air 5 and the outer air 6, which support the upper support plate 2, maintain the shape and angle of the support pad, and give the support pad a certain degree of elasticity. The support plate through groove 202 allows the inflatable air cushion 4 to bend and deform after being compressed, providing a suitable arc fit for the legs and improving the fixation stability of the legs.

[0019] In this embodiment, an air pump 7 is fixedly connected to the center of the upper surface of the lower support plate 1. The air pump 7 is connected to a control panel 8 via an electrical connection wire. The control panel 8 is fixedly connected to the front edge of the upper surface of the lower support plate 1. A diversion air supply pipe 701 is fixedly connected to the air outlet of the air pump 7. The diversion air supply pipe 701 is connected to the support airbag 3 via a flexible hose. A support air valve 301 is installed on the connecting pipe between the support airbag 3 and the diversion air supply pipe 701. The support air valve 301 is connected to the control panel via an electrical connection wire. 8. The inflatable air cushion 4, the inner reinforcing airbag 5, and the outer airbag 6 are connected to the inflatable air cushion 4 via a hose above the shunt air supply pipe 701. An air cushion valve 401 is installed on the pipe connecting the inflatable air cushion 4 and the shunt air supply pipe 701. The air cushion valve 401 is connected to the control panel 8 via an electrical connection wire. By controlling the opening of the air pump 7 and the air cushion valve 401 through the control panel 8, the internal air pressure of the inflatable air cushion 4 can be adjusted, and the elasticity and hardness of the inflatable air cushion 4 can be controlled to provide appropriate support hardness for the patient.

[0020] In Example 2, based on Example 1, the inner reinforcing airbag 5 is connected to the diversion air supply pipe 701 via a hose. An inner air valve 501 is installed on the connecting pipe between the inner reinforcing airbag 5 and the diversion air supply pipe 701. The outer airbag 6 is connected to the diversion air supply pipe 701 via a hose. An outer air valve 601 is installed on the connecting pipe between the outer airbag 6 and the diversion air supply pipe 701. The outer airbag 6 is located in front of the inner reinforcing airbag 5. Both the inner air valve 501 and the outer air valve 601 are connected to the control panel 8 via electrical connection lines. The control panel 8 can control the opening of the inflation pump 7, the support air valve 301, the inner air valve 501, and the outer air valve 601, thereby controlling the air pressure of the support airbag 3, the inner reinforcing airbag 5, and the outer airbag 6. By controlling the air pressure inside the airbags, the support force of the upper support plate 2 can be adjusted, and the folding angle of the upper support plate 2 after being compressed can be adjusted. By distributing different airbags, the elasticity of the support pad can be controlled by selecting the number of inflatable airbags, making it more comfortable to use.

[0021] The working principle of this embodiment is as follows: First, the upper support plate 2 is folded above the lower support plate 1. The air pump 7 and the air cushion valve 401 are opened through the control panel 8 to inflate the air cushion 4, so that the air cushion 4 has a suitable air pressure inside, increasing the hardness of the air cushion 4. The patient's leg is placed on the air cushion 4, so that the air cushion 4 bends and deforms into the support plate groove 202 under the action of gravity. While providing support for the patient, the arc structure provides a suitable arc fit for the leg, improving the fixation stability of the leg. Then, the support air valve 301, inner air valve 501 and outer air valve 601 are opened through the control panel 8, and the air pump 7 inflates the airbag. Under the support of the airbag, the upper support plate 2 is raised upward, and after being raised to an appropriate height, the air valve is closed to maintain an appropriate support height, so that the support has good elasticity and stability, improving comfort.
