DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a quick-to-use medical device protective cover comprises a cover body 1, the cover body 1 is made of transparent plastic, an annular strip 2 is installed at the end of the cover body 1, the annular strip 2 is made of nylon, the interior of the annular strip 2 is hollow, a sliding strip 3 is arranged inside the annular strip 2, one end of the sliding strip 3 is fixedly connected to the inner wall of the annular strip 2, and the sliding strip 3 cannot be completely pulled out from the interior of the annular strip 2, the outer surface of the sliding strip 3 is slidably connected to the inner wall of the annular strip 2, the sliding strip 3 is made of nylon, a fiber surface 4 is arranged on the inner side surface of the sliding strip 3, the fiber surface 4 is a small and soft fiber ring, the outer surface of the annular strip 2 is provided with a bristle surface 5, the bristle surface 5 is harder bristles with hooks, and the fiber surface 4 and the bristle surface 5 can adhere to each other through electrostatic adsorption when in contact to form a firm connection, and the principle is the same as Velcro.

[0025] A stopper 10 is installed on the outer surface of the sliding bar 3 to prevent the sliding bar 3 from completely sliding into the inside of the annular bar 2, making it inconvenient to remove. A first pull ring 11 is installed at one end of the sliding bar 3 away from the annular bar 2 to facilitate pulling.

[0026] The outer surface of the sleeve 1 is provided with a contraction mechanism 6, and the number of the contraction mechanism 6 is multiple. The contraction mechanism 6 includes a pull rope 601, one end of the pull rope 601 is connected to a fixed block 602, one side of the fixed block 602 is connected to the sleeve 1, and the end of the pull rope 601 is fixed to the sleeve 1 through the fixed block 602. The outer surface of the pull rope 601 is slidably connected to a limiting ring 603, and one side of the limiting ring 603 is connected to the sleeve 1. The limiting ring 603 is used to limit the pull rope 601 to prevent the distance between it and the sleeve 1 from being too large, and the pull rope 601 is away from one side of the fixed block 602. A fixing sleeve 604 is provided at the end, one side of the fixing sleeve 604 is connected to the sleeve body 1, the pull rope 601 passes through the inside of the fixing sleeve 604, and a plurality of oblique spikes 605 are provided inside the fixing sleeve 604. The outer surface of the oblique spikes 605 is slidably connected to the pull rope 601, and gradually approaches the center of the fixing sleeve 604 from one end to the other end. When the pull rope 601 slides along the oblique spikes 605, the oblique spikes 605 can slide out. When sliding against the oblique spikes 605, the oblique spikes 605 will pierce into the pull rope 601, making it impossible for the pull rope 601 to move in the reverse direction. The material of the pull rope 601 is fiber.

[0027] The inner wall of the sleeve 1 is connected with a connecting piece 7, and there are multiple connecting pieces 7. Each connecting piece 7 is separated by one end. The material of the connecting piece 7 is the same as that of the sleeve 1, and the sleeve 1 is designed as an integral part. The outer surface of the connecting piece 7 is provided with a U-shaped strip 8, and each connecting piece 7 is provided with a U-shaped strip 8. The end of the U-shaped strip 8 is connected with a sealing strip 9, and one side of the sealing strip 9 is bonded to the sleeve 1 to increase the sealing effect and prevent air leakage from multiple connecting pieces 7. When the sealing strip 9 is uncovered on the sleeve 1, the sealing strip 9 drives the U-shaped strip 8 to move away from the sleeve 1, and the connecting piece 7 is torn off by the U-shaped strip 8, thereby tearing a gap on the side of the sleeve 1, and then the sleeve 1 is removed from the medical device, achieving the effect of easy removal. One end of the sealing strip 9 is connected to the sleeve 1 and can be directly torn off. The other end of the sealing strip 9 is installed with a second pull ring 12 for easy pulling.

[0028] It should be noted that in actual use of the device, the sleeve 1 is first put on the position that needs protection, and the first pull ring 11 is pulled. The first pull ring 11 drives the sliding bar 3 to move to the outside of the annular bar 2, and then the sliding bar 3 is glued to the outer surface of the annular bar 2 so that the fiber surface 4 and the bristle surface 5 are in contact, so that the annular bar 2 and the sliding bar 3 are fixed, so that the annular bar 2 is tightened, and the sleeve 1 is fixed to the medical device. There is no need to use a thick wire rope to tie it up, so that the effect of easy installation is achieved.

[0029] When removing, it is only necessary to tear open the sliding strip 3 and then pull the second pull ring 12. The second pull ring 12 drives the sealing strip 9 to be peeled off on the sleeve 1. The sealing strip 9 drives the U-shaped strip 8 to move away from the sleeve 1, and the connecting piece 7 is torn off by the U-shaped strip 8, thereby tearing a gap on the side of the sleeve 1, and then the sleeve 1 is removed from the medical device, achieving the effect of easy removal.

[0030] According to the different thicknesses of different positions of the medical device, the pull rope 601 can be pulled, and the pull rope 601 slides from one end to the other end of the oblique thorn 605. The oblique thorn 605 prevents the pull rope 601 from moving in the opposite direction, thereby achieving a self-locking effect on the pull rope 601. The pull rope 601 tightens the sleeve 1, so that the sleeve 1 is close to the outer surface of the medical device, thereby reducing the occupied volume of the sleeve 1 and squeezing out the air between the sleeve 1 and the medical device to increase practicality.
