Description

Technical Field

[0001] The present invention relates to the technical field of surgical nursing, in particular to an auxiliary bandaging device used for surgical nursing. Background Art

[0002] Surgical nursing auxiliary bandaging devices are medical aids designed specifically for surgical care. They aim to optimize the bandaging process, improve bandaging effectiveness, and enhance patient comfort. Through scientific design, they help medical staff perform bandaging procedures more accurately and efficiently, reducing errors and inconvenience during the process. They also alleviate pain and discomfort caused by improper bandaging and promote wound healing, making them an indispensable auxiliary tool in surgical nursing.

[0003] However, existing auxiliary bandaging devices cannot automatically lift the patient's arm or leg when in use, and usually require manual operation by medical staff. This not only increases the workload of medical staff, but also makes it difficult to accurately control the force and height during the lifting process, which may cause discomfort to the patient. Moreover, when lifting the patient's arm or leg, the arm or leg is tilted, making it difficult to ensure that the bandage is always parallel to the limb during bandaging. Bandage wrinkles and overlaps are likely to occur, affecting the bandaging effect and hindering wound recovery. In addition, the bandaging process mostly relies on manual wrapping operations and lacks an effective auxiliary bandage wrapping mechanism. The bandaging efficiency is low, making it difficult to meet the needs of surgical care for fast and efficient bandaging, and there are certain disadvantages in the use process.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] like Figures 1-10As shown, this embodiment provides an auxiliary bandaging device for surgical care, including a fixed base 1, a U-shaped mounting frame 2 is fixedly installed on the top of the fixed base 1, a vertical limiting hole groove is opened on the side wall of the U-shaped mounting frame 2, a lifting bar 3 is slidably inserted in the vertical limiting hole groove, and the lifting bar 3 is connected to the U-shaped mounting frame 2 through a lifting drive member 4, a horizontal limiting groove is opened at the bottom of the lifting bar 3, a gathering clamping assembly 5 is installed in the horizontal limiting groove, and the gathering clamping assembly 5 is used to clamp and fix the patient's arm or leg, and a swing extension frame 6 is installed on the U-shaped mounting frame 2, and the swing extension frame 6 is connected to the U-shaped mounting frame 2 through a lifting drive member 4. The transmission connection assembly 7 is rotatably connected to the U-shaped mounting frame 2. A transverse driving assembly 8 is installed on the inner wall of the swing extension frame 6 on one side. A circular sleeve ring 9 is installed on the transverse driving assembly 8. The circular sleeve ring 9 is slidably clamped on the inner wall of the swing extension frame 6 on the other side through a limiting slider 10. An insertion opening is provided on the bottom of the circular sleeve ring 9. A surrounding driving assembly 11 is installed on the inner wall of the circular sleeve ring 9. A limited retracting roller 12 is installed on the surrounding driving assembly 11. The bandage roll is sleeved on the limited retracting roller 12. When in use, the patient's arm or leg is placed on the gathering clamping assembly 5 and fixed by it. Then, according to the bandaging position, the lifting drive 4 is used to adjust the height of the lifting bar 3 to achieve automatic lifting of the patient's arm or leg without the need for manual lifting operation. At the same time, when lifting the patient's arm or leg, the swing extension frame 6 is rotated synchronously through the transmission connection component 7, so that the swing extension frame 6 is at a suitable angle, so that the limit retractable roller 12 remains parallel to the patient's arm or leg, avoiding the overlapping of bandage wrinkles during the bandaging process and improving the auxiliary bandaging effect. When in use, the transverse drive component 8 is started to move the circular sleeve ring 9 to the appropriate position. The bandage roll is put on the limit retractable roller 12, and one end of the bandage is bonded near the patient's affected part to bandage the patient. During the bandaging process, the surrounding drive component 11 can drive the limit retractable roller 12 to rotate, assisting the bandage to surround, so as to achieve the automatic bandaging requirement, thereby completing the auxiliary bandaging operation of the arm or leg and improving the bandaging efficiency.

[0030] As a technical optimization solution of the present invention, specifically Figure 2 As shown, the lifting drive member 4 includes a positioning protrusion plate 401, which is fixed on the outer wall of the U-shaped mounting frame 2. A vertical telescopic rod 402 is fixedly installed on the positioning protrusion plate 401, and the lifting bar 3 is fixedly connected to the telescopic end of the vertical telescopic rod 402. When in use, the vertical telescopic rod 402 fixed on the positioning protrusion plate 401 is started. Since the lifting bar 3 is fixedly connected to the telescopic end of the vertical telescopic rod 402, the extension and contraction of the vertical telescopic rod 402 will drive the lifting bar 3 to slide in the vertical limiting hole groove, thereby realizing the adjustment of the height of the lifting bar 3, so as to automatically lift the patient's limb.

[0031] As a technical optimization solution of the present invention, specifically Figure 5 As shown, the convergent clamping assembly 5 includes a first servo motor 501 and a bidirectional threaded rod 502. The first servo motor 501 is fixed to the inner wall of one end of the transverse limiting groove. The bidirectional threaded rod 502 is rotatably mounted on the inner wall of the other end of the transverse limiting groove through a rotating joint 503. One end of the bidirectional threaded rod 502 is fixedly connected to the output shaft of the first servo motor 501. A clamping thread block 504 is installed on the bidirectional threaded rod 502. The clamping thread block 504 is slidably engaged in the transverse limiting groove. There are two clamping thread blocks 504. A first L-shaped hanging block 505 and a second L-shaped hanging block 506 are fixedly mounted on the two clamping thread blocks 504, which are respectively located at the opposite thread ends of the bidirectional threaded rod 502. A first arc-shaped clamping block 507 and a second arc-shaped clamping block 508 are fixedly mounted on one end of the bottom of the first L-shaped hanging block 505 and the second L-shaped hanging block 506, respectively. Soft fitting blocks 509 are fixedly mounted on the inner walls of the first arc-shaped clamping block 507 and the second arc-shaped clamping block 508. During use, the first servo motor 501 is activated, and its output shaft drives the bidirectional threaded rod 502 to rotate. Because the two clamping thread blocks 504 are respectively located at the opposite thread ends of the bidirectional threaded rod 502 and are slidably engaged in the transverse limiting grooves, they will move toward or away from each other as the bidirectional threaded rod 502 rotates. When moving toward each other, the first L-shaped hanging block 505 and the second L-shaped hanging block 506 are driven closer, thereby bringing the first arc-shaped clamping block 507 and the second arc-shaped clamping block 508 together, and the patient's arm or leg is clamped and fixed through the soft fitting block 509 to meet the stability requirements of the limb during bandaging.

[0032] As a technical optimization solution of the present invention, specifically Figure 3 and Figure 6 As shown, the transmission connection assembly 7 includes a rotating connection base 701 and a lifting rack 702. The rotating connection base 701 is fixed to the outer wall of the U-shaped mounting frame 2. The lifting rack 702 is fixed to the lifting bar 3 via a square column head 703. One end of the swing extension frame 6 is rotatably mounted on the rotating connection base 701 via a synchronous connection shaft 704. A drive gear 705 is fixedly mounted on one end of the synchronous connection shaft 704, and the drive gear 705 is meshed with the lifting rack 702. When the lifting bar 3 is raised or lowered, the lifting rack 702 fixed by the square column head 703 will move synchronously. Because the lifting rack 702 is meshed with the drive gear 705 at one end of the synchronous connection shaft 704, the movement of the lifting rack 702 drives the drive gear 705 to rotate, thereby rotating the synchronous connection shaft 704. One end of the swing extension frame 6 is rotatably mounted on a rotating connection seat 701 fixed to the outer wall of the U-shaped mounting frame 2 through a synchronous connecting shaft 704. Therefore, the rotation of the synchronous connecting shaft 704 will drive the swing extension frame 6 to rotate, thereby realizing the linkage of the swing extension frame 6 and the lifting block 3.

[0033] As a technical optimization solution of the present invention, specifically Figure 7 As shown, the traverse drive assembly 8 includes a second servo motor 801 and a traverse drive screw 802. The second servo motor 801 is fixed to the inner wall of one end of the swing extension frame 6. The traverse drive screw 802 is rotatably mounted on the inner wall of the other end of the swing extension frame 6 via a rotating seat 803. One end of the traverse drive screw 802 is fixedly connected to the output shaft of the second servo motor 801. A traverse slider 804 is threadedly sleeved on the traverse drive screw 802. The traverse slider 804 slides and engages in the swing extension frame 6. The circular sleeve ring 9 is fixedly connected to the traverse slider 804 via a circular positioning column 805. During use, the second servo motor 801 fixed to the inner wall of one end of the swing extension frame 6 is started, and its output shaft drives the traverse drive screw 802 to rotate. The traverse drive screw 802 is mounted on the inner wall of the other end of the swing extension frame 6 via a rotating seat 803, and rotates smoothly. The transverse slide 804 is threadedly mounted on the transverse drive screw 802 and slidably engaged in the swing extension frame 6, and moves laterally with the rotation of the transverse drive screw 802. Since the circular sleeve ring 9 is fixedly connected to the transverse slide 804 via the circular positioning post 805, the movement of the transverse slide 804 drives the circular sleeve ring 9, thereby adjusting the circular sleeve ring 9 to the appropriate position to facilitate subsequent bandaging operations.

[0034] As a technical optimization solution of the present invention, specifically Figure 8As shown, the surround drive assembly 11 includes a first mounting base plate 1101, a second mounting base plate 1102 and an open inner gear ring 1103. The first mounting base plate 1101 and the second mounting base plate 1102 are both fixed on the outer wall of the circular sleeve ring 9, and the first mounting base plate 1101 and the second mounting base plate 1102 are symmetrically distributed. The open inner gear ring 1103 is rotatably mounted on the inner wall of the circular sleeve ring 9. The limiting retractable roller 12 is fixed on the side wall of the open inner gear ring 1103. The first mounting base plate 1101 and the second mounting base plate 1102 are fixed on the outer wall of the circular sleeve ring 9. 2, respectively, are mounted with a first synchronous motor 1104 and a second synchronous motor 1105. A first connecting gear 1106 and a second connecting gear 1107 are fixedly connected to the output shafts of the first and second synchronous motors 1104 and 1105. The first and second connecting gears 1106 and 1107 respectively mesh with the open internal gear ring 1103 from both sides. During operation, the first and second synchronous motors 1104 and 1105, respectively mounted on the first and second mounting base plates 1101 and 1102, are activated. The output shafts of the motors 1104 and 1105 rotate, driving the fixedly connected first and second connecting gears 1106 and 1107 to rotate. Since the first and second connecting gears 1106 and 1107 respectively mesh with the open internal gear ring 1103, which is rotatably mounted on the inner wall of the circular sleeve ring 9, they drive the open internal gear ring 1103 to rotate. The limiting retractable roller 12 is fixed on the side wall of the open inner gear ring 1103. The rotation of the open inner gear ring 1103 drives the limiting retractable roller 12 to make a circular motion, thereby assisting the bandage to wrap around and realize the automatic bandaging function.
