Description

Technical Field

[0001] The invention belongs to the technical field of traction frames, and in particular relates to a traction frame for conveniently replacing gauze. Background Art

[0002] Traction frames are mainly used in orthopedic surgery. By fixing the patient's body parts, the bones are pulled to achieve the purpose of reduction, fixation and treatment. In orthopedic surgeries such as fractures and joint dislocations, the traction frame plays an important role. Its design and function are to help patients with traction treatment to promote recovery from injuries. According to the patient's body shape and injuries, the height, angle and traction of the traction frame are adjusted to facilitate the patient to relax his limbs and carry and pull, so that medical staff can better provide effective medical and nursing services for patients.

[0003] According to different clinical applications, there are many types of medical traction frames, such as Brown frame, Thomas frame, ulna olecranon traction frame, and pediatric bilateral lower limb suspension traction frame, etc. These traction frames have their own characteristics and can be selected according to the patient's specific condition and needs; among them, the Brown frame can put the joints of the affected lower limb in the functional position and prevent the patient from sliding down to the traction side. In the process of contact with the patient's lower limb, this type of traction frame may come into contact with open fractures or patients with wounds, bleeding, and exudation on the affected limbs, so gauze is usually wrapped around the traction frame. After use, the gauze will be residual The gauze will become tighter as the number of layers increases during the wrapping process, making it inconvenient to replace the gauze. Medical staff have to cut off the dirty gauze and then re-wrap it each time. In this case, after the gauze is contaminated with blood, exudate, etc., it cannot be replaced in time and is more likely to become a breeding ground for bacteria, further aggravating the patient's infection or causing new infection, delaying wound healing and causing discomfort to the patient. At the same time, the inconvenient replacement of the gauze on the traction frame will increase the difficulty and workload of medical staff and reduce the efficiency of nursing.

DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0017] Example: like Figure 1-5As shown, the present embodiment provides a traction frame for conveniently replacing gauze, including a base frame 1, both ends of the base frame 1 are fixedly installed with supports 2, and both ends of the base frame 1 are respectively fixedly connected with a U-shaped frame 3 and a support member 12 through the supports 2, an auxiliary frame 4 is integrally provided on the facade of the U-shaped frame 3, and the tops of the U-shaped frame 3 and the auxiliary frame 4 are equipped with a pulley block 5, a first rotating rod 6 and a second rotating rod 7 are rotatably connected to the U-shaped frame 3, a bearing frame 8 is also fixedly connected to the first rotating rod 6, and a supporting rod 9 is fixedly connected to the second rotating rod 7, a fixing rod 10 is fixedly installed on the other end of the bearing frame 8 away from the first rotating rod 6, and a connecting rod 11 is rotatably connected to the middle of the fixing rod 10; The support member 12 has a limiting rod 13 and a support plate 14 , and gauze 15 is wound between the carrier frame 8 and the support rod 9 .

[0018] In a specific application scenario, when the traction frame for convenient gauze replacement is in use, the medical staff first winds the gauze 15 between the support frame 8 and the support rod 9 and tightens the gauze 15, so that the gauze 15 on the upper end surface of the support frame 8 remains flat to support the patient's lower limbs, and supports the end of the support frame 8 through the top of the support plate 14 to maintain the horizontal stability of the support frame 8, and then cooperates with the pulley group 5 to suspend and pull the patient's lower limbs, thereby reducing the burden on the patient's lower limbs and fixing the height of the patient's lower limbs for medical treatment and nursing; and by raising the horizontal height of the support frame 8, The end of the carrier 8 away from the first rotating rod 6 is detached from the support of the upper end surface of the support plate 14. During the lifting process, the carrier 8 is connected to the U-shaped frame 3 through the rotation of the two ends of the first rotating rod 6, driving the carrier 8 to rotate around the first rotating rod 6 as the axis, and gradually reducing the distance between the support rod 9 and the carrier 8 during the rotation, so that the gauze 15 wound between the carrier 8 and the support rod 9 can be loosened from the tightened state, making it easier for medical staff to slide the gauze 15 along the smoothly set carrier 8 and support rod 9 to take it out, and quickly and completely pull the gauze 15 off the carrier 8 for replacement. The following is a further description of the traction frame for convenient gauze replacement of the present invention in combination with this application scenario.

[0019] Further, refer to Figure 1-5 The first rotating rod 6 and the second rotating rod 7 are arranged in parallel, and the supporting frame 8 and the supporting rod 9 are arranged in parallel.

[0020] In the present embodiment, during use of the traction frame for convenient replacement of gauze, in order to enable the gauze 15 wound between the supporting frame 8 and the support rod 9 to remain evenly unfolded, the first rotating rod 6 and the second rotating rod 7 are arranged in parallel, and the supporting frame 8 and the support rod 9 are arranged in parallel, so that the spacing between the supporting frame 8 and the support rod 9 in a horizontal state is fixed, which is convenient for winding of the gauze 15 and the smoothing effect after winding. At the same time, the structure of the supporting frame 8 and the support rod 9 is more stable and can withstand greater pressure and tension, ensuring the stability of the structure, so that the supporting frame 8 can stably support the patient's lower limbs through the gauze 15, and the patient's lower limbs can be directly overlapped on the supporting frame 8, thereby improving the convenience and practicality of the traction frame during use.

[0021] For more details, see Figure 1-5 The other end of the connecting rod 11 away from the fixed rod 10 is rotatably connected to the support rod 9, and the connecting rod 11 is arranged parallel to the U-shaped frame 3.

[0022] In this embodiment, the traction frame for convenient replacement of gauze is used, by setting the other end of the connecting rod 11 to maintain rotational connection with the support rod 9, so that the two ends of the connecting rod 11 are respectively maintained in rotational connection with the support rod 9 and the fixed rod 10, and then when the supporting frame 8 is subjected to force and rotates and displaces, the connecting rod 11 drives the support rod 9 to rotate and displace synchronously, so that the supporting frame 8, the support rod 9, and the connecting rod 11 cooperate with the U-shaped frame 3 to form a movement with a parallelogram as a trajectory, thereby shortening the distance between the supporting frame 8 and the support rod 9, so that the gauze 15 wound between the supporting frame 8 and the support rod 9 is relaxed from a taut state due to the change in the distance, which is convenient for the gauze The cloth 15 is taken out by sliding; at the same time, the supporting frame 8, the support rod 9, and the connecting rod 11 cooperate with the U-shaped frame 3 to form a parallelogram as the trajectory of the movement, which can more easily realize shape change and adaptive adjustment, so that the traction frame for convenient replacement of gauze has a high degree of flexibility while still being stably supported by its stability structure. In the actual operation of medical staff, the parallelogram structure of the supporting frame 8, the support rod 9, and the connecting rod 11 in conjunction with the U-shaped frame 3 is also relatively simple and easy to understand, easy to maintain and adjust, and can adapt to the needs of various shapes and sizes, thereby improving the flexibility and adaptability of the traction frame for convenient replacement of gauze.

[0023] More preferably, referring to Figure 1-5 The support frame 8 and the support rod 9 are both cylindrical and their surfaces are polished and smooth.

[0024] In the present embodiment, during the use of the traction frame for convenient replacement of gauze, since the gauze 15 needs to be wound around the supporting frame 8 and the supporting rod 9 to form a taut state for use, when the gauze 15 needs to be replaced, the wound gauze 15 must be taken out from the supporting frame 8 and the supporting rod 9. Therefore, in the process of sliding the gauze 15 out of the supporting frame 8 and the supporting rod 9, in order to reduce the friction between the gauze 15 and the surface of the supporting frame 8 and the supporting rod 9, the supporting frame 8 and the supporting rod 9 are both cylindrical and polished, so that the gauze 15 can be slid out of the supporting frame 8 and the supporting rod 9 more smoothly, thereby improving the removal and replacement efficiency of the gauze 15 and reducing the difficulty of replacing the gauze 15, thereby improving the convenience of the traction frame for convenient replacement of gauze and the work efficiency of medical staff during use.

[0025] More preferably, referring to Figure 1-5 There are two support members 12 and the spacing between them is adapted to the width of the carrier frame 8 .

[0026] In the present embodiment, during the use of the traction frame for convenient gauze replacement, since the supporting frame 8 as a whole needs to be rotated, in order to maintain the stability of the supporting frame 8 in a horizontal state, two support members 12 are provided and the spacing between them is adapted to the width of the supporting frame 8, so that the end of the supporting frame 8 is supported by the support member 12 when the supporting frame 8 is in a horizontal state, so that it is convenient for the supporting frame 8 to overlap on the top of the support member 12, and the horizontal stability of the supporting frame 8 is maintained, so as to form a stable support for the traction frame for convenient gauze replacement, thereby improving the use effect of the traction frame for convenient gauze replacement.

[0027] Furthermore, refer to Figure 1-5 The upper end surface of the support plate 14 is flattened and provided for overlapping support of both sides of the carrier frame 8 .

[0028] In this embodiment, during the use of the traction frame that is convenient for replacing gauze, when the support member 12 supports the end of the carrier frame 8, in order to facilitate the overlapping of the carrier frame 8 and maintain horizontal stability, the upper end surface of the support plate 14 is flattened to form a stable support for the carrier frame 8, thereby further maintaining the stability of the support for the patient's lower limbs, facilitating medical staff to conduct targeted examinations and treatments, and improving the work efficiency and convenience of medical staff.

[0029] Furthermore, refer to Figure 1-5 , the horizontal height of the upper end surface of the support plate 14 is consistent with the horizontal height of the first rotating rod 6.

[0030] In the present embodiment, during the use of the traction frame for convenient replacement of gauze, since the support frame 8 needs to support the patient's lower limbs when in a horizontal state, it is necessary to maintain the support frame 8 in a balanced state in a horizontal state, and the horizontal height of the upper end surface of the support plate 14 is set to be consistent with the horizontal height of the first rotating rod 6, so that under the horizontal support of the upper end surface of the support plate 14, the support frame 8 can maintain a stable horizontal height and horizontal state, which is convenient for stable bearing of the patient's lower limbs.

[0031] More specifically, see Figure 1-5 , the horizontal height of the upper end surface of the limiting rod 13 is higher than the horizontal height of the upper end surface of the supporting plate 14.

[0032] In the present embodiment, during the use of the traction frame for convenient replacement of gauze, since the supporting frame 8, the support rod 9, and the connecting rod 11 cooperate with the U-shaped frame 3 to form a movement with a parallelogram as the trajectory, it is also necessary to maintain its stability. In order to prevent the deviation of the supporting frame 8, the support rod 9, and the connecting rod 11 when cooperating with the U-shaped frame 3 during movement, which causes the supporting frame 8 to be unable to be accurately overlapped on the support member 12, thereby causing the deviation of the supporting frame 8 and affecting the supporting effect, after the end of the supporting frame 8 is overlapped on the upper end surface of the support plate 14, in order to prevent the end of the supporting frame 8 from shaking, the horizontal height of the upper end surface of the limiting rod 13 is set to be higher than the horizontal height of the upper end surface of the support plate 14, thereby horizontally limiting the end of the supporting frame 8 and maintaining the load stability of the supporting frame 8.

[0033] Working principle: The traction frame of the present invention is convenient for replacing gauze. During use, the medical staff firstly winds the gauze 15 between the support frame 8 and the support rod 9 and tightens the gauze 15, so that the gauze 15 on the upper end surface of the support frame 8 remains flat to support the patient's lower limbs, and supports the end of the support frame 8 through the top of the support plate 14 to keep the level of the support frame 8 stable, and then cooperates with the pulley group 5 to suspend and pull the patient's lower limbs, thereby reducing the burden on the patient's lower limbs and making the patient's lower limbs highly fixed for medical treatment and nursing; When the medical staff needs to replace the gauze 15, they first lift the horizontal height of the carrier frame 8 by hand, so that the end of the carrier frame 8 away from the first rotating rod 6 is separated from the support of the upper end surface of the support plate 14. During the lifting process, the carrier frame 8 is connected to the U-shaped frame 3 at both ends of the first rotating rod 6, driving the carrier frame 8 to rotate around the first rotating rod 6 as the axis; at the same time, the support rod 9 parallel to the carrier frame 8 is also connected to the middle of the fixed rod 10 through the connecting rod 11, and then during the lifting process of the carrier frame 8, the support rod 9 is driven to rotate synchronously around the second rotating rod 7 as the axis. Finally, during the lifting process of the carrier frame 8, the support rod 9 and the connecting rod 11 are driven to move synchronously along the parallelogram trajectory, and during the displacement process, the distance between the support rod 9 and the carrier frame 8 is gradually reduced, so that the gauze 15 wound between the carrier frame 8 and the support rod 9 can be loosened from the tightened state, so that the medical staff can slide and take out the gauze 15 along the smoothly set carrier frame 8 and the support rod 9, and quickly and completely pull the gauze 15 off the carrier frame 8 for replacement.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
