Description

Technical Field

[0001] This utility model relates to the field of surgical draping technology, and in particular to a surgical draping folding device. Background Technology

[0002] In the field of medical supplies manufacturing, surgical drapes, as an important sterile barrier material, have their folding process directly affecting the packaging efficiency and ease of use of the product. Traditional surgical drape folding mainly relies on manual operation, which suffers from low efficiency, hygiene risks, and inconsistent folding standards. Existing automated folding equipment mostly adopts a mechanical clamping design, which not only easily damages the non-woven fabric material but also struggles to adapt to the flexible production needs of drapes of different specifications.

[0003] Therefore, it is essential to invent a folding device for surgical drapes. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a surgical drape folding device. This device solves the problems of low efficiency, hygiene risks, inconsistent folding standards, easy damage to non-woven fabric materials, and difficulty in adapting to the flexible production needs of drapes of different specifications. The surgical drape folding device includes a supporting outer frame, a scissor-type bracket, a connecting skeleton, a drive push rod, a folding gripper, and a surgical drape. The supporting outer frame is suspended from the building roof, and the scissor-type bracket is installed inside two sets of supporting outer frames. The connecting skeleton is rotatably mounted at the hinge point at the upper end of the scissor-type bracket. The drive push rod is rotatably mounted on the connecting skeleton, and the folding gripper is rotatably mounted at the hinge point at the lower end of the scissor-type bracket. The surgical drape is attached to the underside of the folding gripper.

[0005] The supporting outer frame includes a load-bearing frame, a rotating connecting seat, a sliding connecting seat, and a suspension steel cable. The rotating connecting seat is fixedly installed at the upper end of the load-bearing frame and is rotatably connected to the upper end of the scissor bracket. The sliding connecting seat is fixedly installed at the lower end of the load-bearing frame and is slidably connected to the lower end of the scissor bracket.

[0006] The folding gripper includes a rotating support frame, a vertical frame, an adsorption tube, and a negative pressure tube. The rotating support frame is rotatably mounted at the hinge point at the lower end of the scissor-type support, and the vertical frame is fixedly mounted below the rotating support frame. The adsorption tube is fixedly mounted at the bottom of the vertical frame. The negative pressure tube is fixedly mounted at one end of the adsorption tube.

[0007] The supporting outer frame is suspended from the top of the building by suspension steel cables, and the load-bearing frame naturally hangs downward under the action of gravity. The load-bearing frames can move away from or towards each other through the extension and retraction of the scissor brackets. When the load-bearing frames move closer to each other, the distance between them decreases, and the suspension steel cables will tilt inward. When the suspension steel cables tilt inward, they will pull the load-bearing frames and the structures connected to them upward. The whole working process can be understood as the length of the bottom side of the rectangle decreasing, and the two sides tilting inward. Under the premise that the length of the two sides remains unchanged, the bottom side moves upward, forming a trapezoid, thereby driving the folding gripper to retract and move upward.

[0008] The folding gripper can move closer to each other when the scissor-type support retracts, and the suction tube is provided with suction vents below it, and negative pressure is formed by drawing air outward through the negative pressure tube; the suction tube can hold multiple positions of the surgical drape through the suction vents, and fold the surgical drape when it retracts and moves upward.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The support frame of this utility model, through the linkage design of the support frame and the scissor bracket, combined with the negative pressure adsorption function of the adsorption tube, is specifically designed for the automated folding process of surgical drape production lines. Its roof-mounted method with suspended steel cables is suitable for cleanroom requirements, the scissor bracket controlled by the drive push rod can achieve high-speed and precise Z-shaped folding, and the combined structure of the rotating support frame and the vertical frame ensures that the drape material is not damaged during the folding process.

[0011] 2. The folding gripper of this utility model achieves non-destructive gripping and precise folding of surgical drapes through the linkage of the rotating support frame and the vertical frame and the negative pressure adsorption effect of the adsorption tube: its rotating support frame is hinged to the scissor support, and drives the vertical frame to move in space under the action of the drive push rod; the adsorption tube at the bottom of the vertical frame adsorbs the drape through the negative pressure generated by the negative pressure tube, and completes the Z-shaped folding during the retraction of the support.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1 To be continued Figure 4 As shown.

[0020] This utility model provides a surgical drape folding device, including a supporting outer frame 1, a scissor-type bracket 2, a connecting frame 3, a drive push rod 4, a folding grasping frame 5, and a surgical drape 6. The supporting outer frame 1 is suspended from the building roof, and the scissor-type bracket 2 is installed inside two sets of supporting outer frames 1. The connecting frame 3 is rotatably mounted at the hinge point at the upper end of the scissor-type bracket 2. The drive push rod 4 is rotatably mounted on the connecting frame 3, and the folding grasping frame 5 is rotatably mounted at the hinge point at the lower end of the scissor-type bracket 2. The surgical drape 6 is attached to the underside of the folding grasping frame 5.

[0021] The supporting outer frame 1 includes a load-bearing frame 11, a rotating connecting seat 12, a sliding connecting seat 13, and a suspension steel cable 14. The rotating connecting seat 12 is fixedly installed on the upper end of the load-bearing frame 11 and is rotatably connected to the upper end of the scissor bracket 2. The sliding connecting seat 13 is fixedly installed on the lower end of the load-bearing frame 11 and is slidably connected to the lower end of the scissor bracket 2.

[0022] The folding gripper 5 includes a rotating support frame 51, a vertical frame 52, an adsorption tube 53, and a negative pressure tube 54. The rotating support frame 51 is rotatably mounted at the hinge point at the lower end of the scissor bracket 2, and the vertical frame 52 is fixedly mounted below the rotating support frame 51. The adsorption tube 53 is fixedly mounted at the bottom of the vertical frame 52. The negative pressure tube 54 is fixedly mounted at one end of the adsorption tube 53.

[0023] The supporting outer frame 1 is suspended from the top of the building by the suspension steel cable 14, and the load-bearing frame 11 naturally hangs downward under the action of gravity. The load-bearing frames 11 can move away from or closer to each other by the extension and retraction of the scissor bracket 2. When the load-bearing frames 11 move closer to each other, the distance between the load-bearing frames 11 decreases, and the suspension steel cable 14 will tilt inward. When the suspension steel cable 14 tilts inward, it will pull the load-bearing frame 11 and the structure connected to the load-bearing frame 11 to move upward. The whole working process can be understood as the length of the bottom side of the rectangle decreases, and the two sides will tilt inward. Under the premise that the length of the two sides remains unchanged, the bottom side moves upward to form a trapezoid, thereby driving the folding gripping frame 5 to retract and move upward.

[0024] The folding gripper 5 can move closer to each other when the scissor-type support 2 retracts, and the suction tube 53 is provided with suction vents below it, and negative pressure is formed by drawing air out through the negative pressure tube 54; the suction tube 53 can hold multiple positions of the surgical drape 6 through the suction vents, and fold the surgical drape 6 when it retracts and moves upward.

[0025] This surgical drape folding device achieves automated and efficient folding through a mechanical linkage system: after the suspension steel cable 14 suspends and positions the supporting outer frame 1, the drive push rod 4 drives the scissor bracket 2 to extend and retract, while the folding gripper 5 uses the negative pressure of the suction tube 53 to smoothly grip the surgical drape 6; as the scissor bracket 2 retracts, the suspension steel cable 14 generates an oblique pulling force, causing the entire device to rise, and the rotating support frame 51 and the vertical frame 52 work together to complete the precise folding action. This equipment adopts a non-contact gripping design, completing standardized folding with an accuracy of ±1mm within 1 second. Its modular structure can adapt to different drape specifications, perfectly meeting the stringent requirements of medical supply production lines for efficient, clean, and precise folding.

[0026] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
