Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a restraint aid with adjustable activity space and a method of using the restraint aid. Background Art

[0002] In the field of medical device technology, restraint aids, as auxiliary medical equipment, play a vital role in various examinations and treatments, especially in the field of gastroscopy. Since the patient needs to maintain a specific posture during the examination and body movements are subject to certain restrictions, it is particularly important to design a restraint aid that can effectively restrain the patient's body while ensuring that the examination proceeds smoothly and the patient is comfortable.

[0003] Traditional gastroscopy restraint aids mostly adopt a fixed design, that is, the size and shape of the aids are fixed, which makes it difficult to adapt to patients of different body shapes. Fixed restraint aids cannot be flexibly adjusted according to the patient's body shape, resulting in poor restraint effects and may even cause discomfort to patients due to excessive restraint. Secondly, traditional aids lack the necessary adjustment mechanism during the restraint process, making it difficult for doctors to make fine adjustments according to the patient's actual situation during the operation, thereby affecting the accuracy and safety of the examination and resulting in poor use of the device, so staff need to improve it. Summary of the invention

[0022] S6. After the examination, remove the restraint device in reverse order to ensure that it does not cause any harm to the patient, and clean and disinfect all parts of the assistive device in accordance with the hygiene requirements of medical equipment for next use.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) By installing the sleeve frame, winding rod, restraint belt, limit frame, limit clamping teeth, connecting toothed disc, extrusion spring and handle, when in use, the multiple installation sleeve frames slidably connected on the first connecting frame can be adjusted to suit patients of different sizes. The restraint belt wrapped around the surface of the winding rod is used for actual restraint, and its length can be adjusted by rotating the winding rod. The limit clamping teeth on the inner wall of the limit frame mesh with the connecting toothed disc on the surface of the winding rod, thereby realizing the self-locking function after the winding rod is rotated to prevent the restraint belt from being accidentally loosened. One end of the extrusion spring overlaps the connecting toothed disc to provide elastic support for the meshing of the connecting toothed disc and the limit clamping teeth, thereby ensuring the reliability of the self-locking function. By squeezing the handle to push the winding rod forward, the connecting toothed disc on the surface of the winding rod compresses the extrusion spring, thereby making the connecting toothed disc free from the restriction of the limit clamping teeth, thereby facilitating the convenient retraction and release of the restraint belt on the surface of the winding rod, thereby realizing the flexible adjustment of the length of the restraint belt, and ensuring the stability and safety during the restraint process.

[0025] (2) By setting the installation sleeve, the first positioning column, the positioning groove, the sliding groove, the sliding block, the fixed block, the second positioning column, the second traction plate and the second compression spring, when in use, the first positioning column cooperates with the positioning groove so that the installation sleeve can slide and position stably in the first connecting frame, thereby ensuring the stability of the auxiliary tool during use. The setting of the first traction plate and the first compression spring provides a reset force for the installation sleeve, so that the user can easily restore the installation sleeve to its initial state after adjusting the position of the installation sleeve. The design of the sliding groove and the sliding block further enhances the smoothness of the sliding of the installation sleeve in the first connecting frame. The fixing block serves as the fixing structure at the front end of the restraint belt, and is slidably connected to the inner wall of the second connecting frame, so that the length and position of the restraint belt can be adjusted as needed. The insertion of the second positioning column and the inner wall of the fixing block, as well as the cooperation of the second traction plate and the second compression spring, provide stable support and reset force for the fixing block, so that the restraint belt can maintain stable tension after adjustment, and the fixing structures at both ends of the restraint belt can be moved and fixed synchronously, thereby achieving the stability and flexibility of the assistive device, and allowing the user to easily adjust the length and position of the restraint belt according to actual needs to meet the usage requirements in different scenarios.

[0026] (3) Through the arrangement of the first connecting frame, the second connecting frame, the mounting clamp, the threaded rod, the rotating handle and the extrusion plate, when in use, the mounting clamps at the bottom of the first connecting frame and the second connecting frame are plugged into the two sides of the bed, and the user can adjust the extension length of the threaded rod by rotating the rotating handle, thereby controlling the pressure of the extrusion plate on the mounting surface. The surface of the extrusion plate is plugged into the inner wall of the mounting clamp and moves with the lifting and lowering of the threaded rod, thereby realizing fine adjustment of the installation firmness of the assistive device, which not only ensures the stability of the assistive device during use, but also facilitates the user to fine-tune the position according to actual needs, thereby improving the adaptability and ease of use of the assistive device, thereby ensuring the stable installation of the assistive device and facilitating the user to adjust the position of the assistive device.

[0048] Embodiment 4:

[0049] See also Figures 1 to 6 As shown, a method for using a restraint assistive device capable of adjusting an activity space comprises the following steps:

[0050] S1. Connect the first connecting frame and the second connecting frame to the two sides of the gastroscopy examination bed through the mounting clamps at the bottom, respectively, to ensure that the auxiliary device is firmly clamped in the appropriate position of the bed, and use a threaded rod to penetrate the mounting clamps, and adjust the extension length of the threaded rod by rotating the handle, so as to finely adjust the pressure of the extrusion plate on the mounting surface to ensure the stability of the auxiliary device during use;

[0051] S2. According to the patient's body shape and gastroscopy requirements, slide the multiple mounting frames on the first connecting frame to appropriate positions, so that the assistive device can adapt to patients of different sizes and ensure that the restraint belt can correctly apply restraint;

[0052] S3. Rotate the winding rod inside the mounting frame to adjust the length of the restraint belt wrapped around its surface. By rotating the winding rod, the restraint belt can be released or tightened to meet the restraint requirements of different patients. After adjusting the length of the restraint belt, the self-locking function of the winding rod is realized by using the meshing relationship between the limit teeth on the inner wall of the limit frame and the connecting toothed disc on the surface of the winding rod to prevent the restraint belt from being accidentally loosened.

[0053] S4. Fix the adjusted restraint belt to the patient's body to ensure that it does not move at will during the gastroscopy. Push the winding rod forward by squeezing the handle so that the restraint belt can maintain stable tension after adjustment, ensuring the safety of the patient and the smooth progress of the examination.

[0054] S5. During the gastroscopy, regularly check the tension of the restraint belt and the patient's comfort to ensure the correct use of the restraint device and the patient's safety. If adjustments are needed, repeat S3 and S4 to meet different needs during the examination.

[0055] S6. After the examination, remove the restraint device in reverse order to ensure that it does not cause any harm to the patient, and clean and disinfect all parts of the assistive device in accordance with the hygiene requirements of medical equipment for next use.

[0056] Embodiment five:

[0057] See also Figures 1 to 6 As shown, during gastroscopy, patients usually need to maintain a certain body position so that the doctor can clearly observe the stomach condition and perform necessary operations. However, due to the discomfort and tension that gastroscopy may cause, some patients may move their bodies or resist the examination, which not only affects the accuracy of the examination, but also may increase the risk to the patient and the difficulty of the doctor's operation.

[0058] First, the first connecting frame 1 and the second connecting frame 2 of the restraint auxiliary device with adjustable activity space are fixed on both sides of the gastroscopy examination bed respectively, and the auxiliary device is firmly clamped in the appropriate position of the bed by the installation clamp 23. Then, the threaded rod 24 is used to penetrate the installation clamp 23, and the extension length of the threaded rod is adjusted by rotating the handle 25. This step is used to finely adjust the pressure of the extrusion plate 26 on the installation surface to ensure the stability of the auxiliary device during use. According to the patient's body shape and examination requirements, the multiple installation sleeves 3 on the first connecting frame 1 are slid to the appropriate position. The winding rod 4 that is rotatably connected inside the installation sleeve 3 is wrapped with a restraint belt 5, which is used to properly restrain the patient's body. By rotating the winding rod 4, the length of the restraint belt 5 can be adjusted to meet the restraint requirements of different patients. At the same time, the limiting clamping teeth 9 on the inner wall of the limiting frame 8 are meshed with the connecting toothed disc 10 on the surface of the winding rod 4 to realize the self-locking function after the winding rod 4 is rotated to prevent the restraint belt 5 from being accidentally loosened.

[0059] After ensuring that the patient is comfortable and stable, the doctor begins to perform gastroscopy. At this time, the restraint belt 5 of the restraint aid can effectively limit the patient's body movement, making the examination process smoother and safer. If the patient's body position or restraint strength needs to be adjusted during the examination, the doctor can easily adjust the position of the installation frame 3, rotate the winding rod 4 to change the length of the restraint belt 5, or rotate the handle 25 to fine-tune the installation firmness of the aid.

[0060] After the gastroscopy is completed, the doctor can easily release the restraint belt 5 by reversely rotating the winding rod 4 and releasing the self-locking function, and restore the various components of the auxiliary device to their initial state. The various components of the auxiliary device are designed to be easy to clean and disinfect to ensure safety and hygiene for the next use.

[0061] By using the restraint aid with adjustable activity space, the patient's body movement can be effectively restricted during gastroscopy, improving the accuracy and safety of the examination. At the same time, the design of the aid takes into account the patient's comfort and the doctor's convenience of operation, making the examination process smoother and more efficient. In addition, the various components of the aid are easy to clean and disinfect, meeting the hygiene requirements of medical equipment.

[0062] Working principle: When in use, the multiple installation sleeves 3 slidably connected on the first connecting frame 1 can adjust their positions as needed to adapt to patients of different sizes. The winding rod 4 rotatably connected inside the installation sleeve 3 is a storage and release mechanism for the restraint belt 5. The restraint belt 5 wrapped around the surface of the winding rod 4 is used for actual restraint, and its length can be adjusted by rotating the winding rod 4. The movable groove 6 provides a rotation space for the limit plate 7 to ensure that the winding rod 4 will not be hindered during rotation. The cooperation between the limit plate 7 and the movable groove 6, and the penetration of the limit frame 8 on the winding rod 4, together limit the axial movement of the winding rod 4, enhance the stability of the structure, and the limit card on the inner wall of the limit frame 8 The teeth 9 are meshed with the connecting toothed disc 10 on the surface of the winding rod 4, realizing the self-locking function after the winding rod 4 is rotated, preventing the restraining belt 5 from being accidentally loosened. One end of the extrusion spring 11 is overlapped on the connecting toothed disc 10 to provide elastic support for the engagement of the connecting toothed disc 10 with the limiting tooth 9, ensuring the reliability of the self-locking function. The winding rod 4 is pushed forward by squeezing the handle 12, so that the connecting toothed disc 10 on the surface of the winding rod 4 compresses the extrusion spring 11, so that the connecting toothed disc 10 is free from the restriction of the limiting tooth 9, thereby facilitating the convenient retraction and release of the restraining belt 5 on the surface of the winding rod 4. The first positioning column 13 and the positioning groove 16 enable the mounting frame 3 to slide stably in the first connecting frame 1 The first traction plate 14 and the first compression spring 15 provide a reset force for the installation sleeve 3, so that the user can easily restore the installation sleeve 3 to its initial state after adjusting the position of the installation sleeve 3. The design of the sliding groove 17 and the sliding block 18 further enhances the smoothness and stability of the sliding of the installation sleeve 3 in the first connecting frame 1. The fixed block 19 is used as a sliding connection between the constraint belt 5 and the inner wall of the second connecting frame 2, so that the length and position of the constraint belt 5 can be adjusted as needed. The plugging of the second positioning column 20 with the inner wall of the fixing block 19, and the cooperation of the second traction plate 21 and the second compression spring 22 are for fixing. The fixed block 19 provides stable support and reset force, so that the restraint belt 5 can maintain stable tension after adjustment, and the fixed structures at both ends of the restraint belt 5 can be moved and fixed synchronously. The first connecting frame 1 and the second connecting frame 2 are plugged into the two sides of the bed through the mounting clamp 23 at the bottom. The threaded rod 24 passes through the mounting clamp 23 and is operated by turning the handle 25. The user can adjust the extension length of the threaded rod 24 by rotating the handle 25, and then control the pressure of the extrusion plate 26 on the installation surface. The surface of the extrusion plate 26 is plugged into the inner wall of the mounting clamp 23, and moves with the rise and fall of the threaded rod 24, thereby realizing fine adjustment of the installation firmness of the auxiliary device.

8. A method for using a restraint aid with adjustable activity space, applicable to the restraint aid with adjustable activity space according to claims 1 to 7, characterized in that: The following steps are involved: S1. Connect the first connecting frame and the second connecting frame to the two sides of the gastroscopy examination bed through the mounting clamps at the bottom, respectively, to ensure that the auxiliary device is firmly clamped in the appropriate position of the bed, and use a threaded rod to penetrate the mounting clamps, and adjust the extension length of the threaded rod by rotating the handle, so as to finely adjust the pressure of the extrusion plate on the mounting surface to ensure the stability of the auxiliary device during use; S2. According to the patient's body shape and gastroscopy requirements, slide the multiple mounting frames on the first connecting frame to appropriate positions, so that the assistive device can adapt to patients of different sizes and ensure that the restraint belt can correctly apply restraint; S3. Rotate the winding rod inside the mounting frame to adjust the length of the restraint belt wrapped around its surface. By rotating the winding rod, the restraint belt can be released or tightened to meet the restraint requirements of different patients. After adjusting the length of the restraint belt, the self-locking function of the winding rod is realized by using the meshing relationship between the limit teeth on the inner wall of the limit frame and the connecting toothed disc on the surface of the winding rod to prevent the restraint belt from being accidentally loosened. S4. Fix the adjusted restraint belt to the patient's body to ensure that it does not move at will during the gastroscopy. Push the winding rod forward by squeezing the handle so that the restraint belt can maintain stable tension after adjustment, ensuring the safety of the patient and the smooth progress of the examination. S5. During the gastroscopy, regularly check the tension of the restraint belt and the patient's comfort to ensure the correct use of the restraint device and the patient's safety. If adjustments are needed, repeat S3 and S4 to meet different needs during the examination. S6. After the examination, remove the restraint device in reverse order to ensure that it does not cause any harm to the patient, and clean and disinfect all parts of the assistive device in accordance with the hygiene requirements of medical equipment for next use.
