DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please see attached Figure 1 - Attachment Figure 8 An embodiment of the present invention provides an auxiliary fixation device for critically ill patients in clinical medicine, including a supporting bed frame 1, a pressure pad 3 is arranged inside the supporting bed frame 1, which is used to support the patient's body, and multiple pressure pads 3 are connected through a rotating component 4. A lifting mechanism 5 is fixedly connected inside the supporting bed frame 1, and the output end of the lifting mechanism 5 is connected to the pressure pad 3, which is used to lift the pressure pad 3 at multiple angles. A fixing plate 6 is fixedly connected to one side of the top of the pressure pad 3, and a supporting mechanism 7 is slidably connected inside the fixing plate 6, which is used to support the patient's legs. A uniformly distributed positioning component 2 is installed on the top of the pressure pad 3.

[0031] The lifting mechanism 5 includes a servo motor 501, which is fixedly connected to one side of the inner part of the supporting bed frame 1. The output end of the servo motor 501 is fixedly connected to an end cam 502, and the outer wall of the end cam 502 is slidably connected to a positioning seat 503, and one end of the outer wall of the positioning seat 503 is fixedly connected to one end of a support rod 504. A T-slot 505 is provided at the bottom of the pressure pad 3, and a T-block 506 is slidably connected inside the T-slot 505. A rotating shaft 507 is fixedly connected to the outer wall of the T-block 506, and the other end of the support rod 504 is rotatably connected to the inside of the rotating shaft 507.

[0032] A support fork 509 is installed on the outer wall of the positioning seat 503, and rollers 508 are rotatably connected to both ends of the support fork 509, and the rollers 508 slide on the outer wall of the end face cam 502;

[0033] Specifically, when the angle of the pressure pad 3 needs to be adjusted, the servo motor 501 is started, and the servo motor 501 drives the end cam 502 to rotate. As the end cam 502 rotates, the contact position between its outer wall and the positioning seat 503 changes. Since the positioning seat 503 is restricted by the support rod 504 and cannot move at will, the roller 508 rolls along the outer wall of the end cam 502 under the support of the support fork 509. This rolling can reduce friction and make the movement of the positioning seat 503 smoother. When the end cam 502 pushes the positioning seat 503 to move, the support rod 504 drives the rotating shaft 507 to move, and the T-block 506 slides in the T-slot 505, so that the pressure pad 3 can achieve multi-angle lifting action. This lifting action can be adjusted according to the patient's body posture requirements to provide a more comfortable and appropriate support angle for the patient.

[0034] The rotating assembly 4 includes a horizontal axis 401, which is connected to a pressure pad 3 on one side, and a vertical axis 402 is rotatably connected inside the horizontal axis 401, and an outer wall of the vertical axis 402 is fixedly connected to the pressure pad 3 on the other side, and a support plate 403 is fixedly connected to the bottom of the vertical axis 402, and the support plate 403 is fixedly connected to the support bed frame 1;

[0035] Specifically, when the patient's body needs to be rotated and adjusted in the lateral direction, one side of the pressure pad 3 will rotate around the horizontal axis 401 relative to the vertical axis 402. Since the bottom of the vertical axis 402 is fixed to the supporting bed frame 1 through the support plate 403, the stability of the rotation can be guaranteed. This rotation method allows the adjacent pressure pads 3 to change angles relatively flexibly, which can assist the patient to stand up or sideways, and better adapt to the changes in the patient's body posture in different situations. For example, when the patient needs to turn sideways or the medical staff needs to perform special care operations on the patient, the rotating component 4 can conveniently adjust the layout of the pressure pad 3, and the lifting mechanisms 5 are respectively distributed at the bottom of different pressure pads 3. When the lifting mechanisms 5 lift the horizontal pressure pad 3, it can assist in lifting the patient's waist. When the lifting mechanisms 5 lift the vertical pressure pads 3 on both sides, it can assist in driving the patient's body to turn sideways, so as to facilitate treatment of various parts of the patient's body.

[0036] The support mechanism 7 includes an adjustment slot 701, which is provided inside the fixed plate 6, and an adjustment block 702 is slidably connected inside the adjustment slot 701, and one end of a telescopic rod 703 is fixedly connected to the top of the adjustment block 702, and the other end of the telescopic rod 703 is fixedly connected to a support leg ring 704, and an auxiliary component 8 is slidably connected inside the support leg ring 704, which is used to assist in strengthening the support stability of the support leg ring 704;

[0037] Arc rings 705 are fixedly connected to both sides of the outer wall of the support leg ring 704;

[0038] The outer wall of the arc ring 705 is provided with a rubber pad 707;

[0039] The supporting mechanism 7 further includes an electric push rod 706, which is fixedly connected to one side of the inner wall of the adjusting slot 701, and the output end of the electric push rod 706 is connected to the adjusting block 702;

[0040] Specifically, when it is necessary to adjust the support height for the patient's legs, start the electric push rod 706, which pushes the adjustment block 702 to slide in the adjustment slot 701, and the telescopic rod 703 can move up and down, thereby changing the height position of the support leg ring 704. Under the coordinated extension and retraction of the electric push rod 706 and the telescopic rod 703 within a certain range, it can adapt to the support requirements of legs of different lengths. The arc ring 705 can better fit the curve of the patient's legs, increase the stability and comfort of the knee joint or leg support, and the rubber pad 707 can prevent excessive friction between the patient's legs and the arc ring 705, and also has a certain anti-slip effect.

[0041] The auxiliary component 8 includes a positioning groove 801, which is provided inside the supporting leg ring 704, a positioning plate 802 is fixedly connected to the middle of the positioning groove 801, one end of a tension spring 803 is installed on both sides of the outer wall of the positioning plate 802, and the other end of the tension spring 803 is fixedly connected to a positioning block 804, the positioning block 804 is slidably connected to the inside of the positioning groove 801, and a clamping plate 805 is fixedly connected to the top of the positioning block 804;

[0042] Specifically, the auxiliary component 8 inside the support leg ring 704 further enhances the support effect on the legs. When the patient's legs are placed in the support leg ring 704, the legs will exert pressure on the splint 805, causing the splint 805 to move to both sides. The splint 805 drives the positioning block 804 to slide in the positioning groove 801, and the tension spring 803 is stretched. The elastic force of the tension spring 803 will automatically adjust according to the pressure of the legs, so that the splint 805 exerts a moderate clamping force on the legs, thereby better fixing the legs, preventing the legs from shaking in the support leg ring 704, improving the stability of the leg support, and providing reliable support for the patient's legs.

[0043] The positioning assembly 2 includes a positioning belt 201, one end of which is mounted on the top of the pressure pad 3, and the other end of the positioning belt 201 is mounted with a Velcro 202, and the top of the pressure pad 3 is mounted with evenly distributed positioning stickers 203, and the Velcro 202 corresponds to the positioning stickers 203;

[0044] Specifically, when the patient's body needs to be fixed, the positioning belt 201 is passed around the patient's body, and then the Velcro 202 is pasted on the corresponding positioning sticker 203. The matching mode of the Velcro 202 and the positioning sticker 203 is convenient and fast, and can be flexibly adjusted according to the size of the patient's body and the part that needs to be fixed. Through the fixation of multiple positioning belts 201, the movement of the patient's body on the pressure pad 3 can be effectively limited, ensuring that the patient maintains a stable posture during treatment or nursing, and at the same time, it will not cause excessive pressure on the patient's body.

[0045] Working principle: An embodiment of the present invention provides a medical clinical critically ill patient auxiliary fixation device, which aims to provide a stable, comfortable and flexibly adjustable support and fixation environment for critically ill patients to meet various needs during treatment and nursing. These functions are achieved through the coordinated work of components such as the supporting bed frame 1, the pressure pad 3, the rotating component 4, the lifting mechanism 5, the fixed plate 6, the supporting mechanism 7 and the positioning component 2.

[0046] When the servo motor 501 is started, its output end drives the end cam 502 to rotate. As the end cam 502 rotates, the contact position between its outer wall and the positioning seat 503 changes continuously. Since the positioning seat 503 is restricted by the support rod 504, it cannot move freely. However, the rollers 508 at both ends of the support fork 509 installed on the outer wall of the positioning seat 503 roll along the outer wall of the end cam 502 under the support of the support fork 509. This rolling contact mode between the rollers 508 and the end cam 502 effectively reduces friction, making the movement of the positioning seat 503 smoother. When the end cam 502 pushes the positioning seat 503 to move, the support rod 504 drives the rotating shaft 507 to move, thereby making the T-block 506 slide in the T-slot 505, and finally realizing the multi-angle lifting action of the pressure pad 3. This lifting action can be adjusted according to the patient's body posture requirements, providing the patient with a more comfortable support angle that is more in line with his or her physical condition, helping the patient to maintain a suitable body position, and reducing the body pressure and injury risk caused by body discomfort.

[0047] When the patient's body needs to be rotated and adjusted in the horizontal direction, the rotating assembly 4 starts to work, and one side of the pressure pad 3 will rotate around the horizontal axis 401 relative to the vertical axis 402. The bottom of the vertical axis 402 is firmly fixed to the supporting bed frame 1 through the support plate 403. This structure ensures the stability of the rotation. The angles between adjacent pressure pads 3 can be relatively flexibly changed, which can assist the patient to move straight or sideways. When medical staff perform special nursing operations for patients, such as sideways examination, treatment of side wounds, etc., or when the patient himself needs to adjust his position, such as turning over, the rotating assembly 4 can conveniently adjust the layout of the pressure pad 3. Moreover, the lifting mechanism 5 is respectively distributed at the bottom of different pressure pads 3. When the lifting mechanism 5 lifts the horizontal pressure pad 3, it can assist in lifting the patient's waist. When the lifting mechanism 5 lifts the vertical pressure pads 3 on both sides, it can assist in turning the patient's body sideways, which is convenient for treating various parts of the patient's body and improves the convenience and efficiency of medical operations.

[0048] The height adjustment of the support mechanism 7 relies on the electric push rod 706. When the support height of the patient's legs needs to be adjusted, the electric push rod 706 is started, and the electric push rod 706 pushes the adjustment block 702 to slide in the adjustment slot 701. The movement of the adjustment block 702 drives the telescopic rod 703 to move up and down, thereby changing the height position of the support leg ring 704. Under the coordinated expansion and contraction of the electric push rod 706 and the telescopic rod 703 within a certain range, it can adapt to the support requirements of legs of different lengths. The arc rings 705 on both sides of the outer wall of the support leg ring 704 can better fit the curve of the patient's legs, increase the stability and comfort of the knee joint or leg support. The rubber pad 707 installed on the outer wall of the arc ring 705 can prevent excessive friction between the patient's legs and the arc ring 705, and also play a certain anti-slip role, preventing the patient's legs from accidentally sliding during the support process, and ensuring the safety and effectiveness of the support.

[0049] The auxiliary component 8 is located inside the support leg ring 704 and is used to enhance the support effect on the legs. When the patient's legs are placed in the support leg ring 704, the legs will produce pressure on the splint 805. This pressure causes the splint 805 to move to both sides. The splint 805 drives the positioning block 804 to slide in the positioning groove 801. At the same time, the tension spring 803 is stretched. The elastic force of the tension spring 803 will automatically adjust according to the pressure of the legs, so that the splint 805 produces a moderate clamping force on the legs. In this way, the legs can be better fixed and prevented from shaking in the support leg ring 704, thereby improving the stability of the leg support, providing reliable support for the patient's legs, and ensuring the patient's comfort and safety during the leg support process.

[0050] The positioning component 2 is used to fix the patient's body to ensure that it maintains a stable posture during treatment or nursing. When the patient's body needs to be fixed, the positioning belt 201 is passed around the patient's body, and then the Velcro 202 is pasted on the corresponding positioning sticker 203. Through the fixation of multiple positioning belts 201, the movement of the patient's body on the pressure pad 3 can be effectively restricted without causing excessive pressure on the patient's body. Under the premise of ensuring the stability of the patient, the patient's comfort is improved, which is conducive to the smooth progress of treatment and nursing work.
