Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and more specifically, to a protective sleeve suitable for PICC placement. Background Technology

[0002] When a patient requires intravenous access during hospital treatment, the doctor may choose to place a PICC (Peripherally Inserted Central Catheter). A PICC is a long-term indwelling venous catheter, typically used for treatment purposes such as intravenous infusion, blood transfusion, nutritional support, and drug infusion. To protect the safety and hygiene of the PICC catheter, a protective sleeve is usually worn by the patient. This protective sleeve is a soft, tubular sleeve used to cover the insertion site and surrounding area of ​​the PICC catheter to reduce the risk of infection and catheter dislodgement. Since the PICC catheter needs to be exposed again during use, it is necessary to perform a surrounding and exposure procedure on the PICC catheter.

[0003] In related technologies, during the use of the protective sleeve, medical staff typically hold one end of the sleeve by the elastic band and pull it outwards, then move the sleeve downwards to remove it, exposing the PICC catheter for use.

[0004] However, in the current use of protective sleeves, the PICC catheter is not easily accessible due to the method of removing and covering it, which makes the operation of the PICC catheter inconvenient. In addition, different patients have different arm circumferences, and the protective sleeve may be too tight or too loose when worn with elastic bands. As a result, the protective sleeve cannot protect the PICC catheter when it is in use, which affects the adaptability, ease of use and protective effect of the protective sleeve.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Reference Figures 1-4 This utility model provides a technical solution: a protective sleeve suitable for PICC placement, including a sleeve body 1 and a tightening adjustment mechanism. Elastic bands 2 are installed at the top and bottom of the front side of the sleeve body 1. A fixing strap 3 is fixedly connected to the front side of the elastic bands 2. When the elastic bands 2 are used with the sleeve body 1, medical staff can adjust the tightness of the elastic bands 2 to tighten the sleeve body 1 according to the patient's actual arm circumference, so as to avoid the sleeve body 1 being worn too loosely or too tightly, thus improving the wearability of the sleeve body 1.

[0032] Reference Figures 1-4 In a preferred embodiment, the tightening adjustment mechanism includes a tightening sleeve 4, which is fixedly connected to the top and bottom of the front side of the sleeve 1. A connecting ring 5 is movably connected inside the tightening sleeve 4, and the connecting ring 5 is sleeved and connected to the elastic band 2. Velcro 6 is fixedly connected to the left side of the fixing band 3. Velcro 7 is fixedly connected to the top and bottom of the surface of the sleeve 1, and Velcro 8 is fixedly connected to the right side of the elastic band 2. Several Velcro 8s are provided and are evenly distributed. The opening and closing operation mechanism is fixedly connected to the left side of the sleeve 1. First, the sleeve 1 is held and placed on the outside of the PICC catheter placed in the patient's arm. Then, according to the actual arm circumference of the patient's arm, the fixing band 3 is held and the elastic band 2 is wrapped around the outside of the sleeve 1, so that the two sides of the inner side of the sleeve 1 fit the patient's arm. During this process, Velcro 6 moves with the fixing band 3. When the patient's arm circumference is large and the fixing strap 3 cannot wrap around the sleeve 1 once, the Velcro 6 and Velcro 7 are attached. When the patient's arm circumference is small and the fixing strap 3 can wrap around the sleeve 1 once, the adhesive strip and Velcro 8 are attached. The fixing strap 3 is used to wrap and position the elastic band 2, ensuring the adaptability of the sleeve 1. The opening and closing mechanism includes an opening and closing strip 9, an opening and closing plate 10, and an operating port 11. The opening and closing strip 9 is fixedly connected to the left side of the sleeve 1, the opening and closing plate 10 is fixedly connected to the bottom of the opening and closing strip 9, and the operating port 11 is located on the left side of the sleeve 1 and the right side of the opening and closing plate 10. When the adhesive strip is used with the sleeve 1, it can provide medical staff with space to open and close the sleeve 1 for medical operations, avoiding situations where it is difficult to perform medical operations when using the sleeve 1. Therefore, it improves the ease of use and protective effect of the sleeve 1.

[0033] Reference Figures 2-3 In a preferred embodiment, by providing a force-applying piece 12 at the bottom of the operating opening 11 on the left side of the sleeve 1, with the top of the force-applying piece 12 fixedly connected to the bottom of the opening and closing piece 10, the user can apply force to lift the opening and closing piece 10 and separate the hook and loop fasteners 13 and 14 when the hook and loop fasteners 4 and 5 are used together. This avoids the situation where the opening and closing piece 10 is difficult to lift when used, thus improving the ease of use of the opening and closing piece 10. The left side of the sleeve 1 is movably connected to the hook and loop fasteners 4 and 13, which is located outside the operating opening 11. The left side of the hook and loop fasteners 4 and 13 is fixedly connected to the right side of the opening and closing piece 10. This provides the medium for the opening and closing piece 10 to adhere to the sleeve 1 when used with the operating opening 11, avoiding the situation where the opening and closing piece 10 is difficult to close and connect with the sleeve 1, thus improving the ease of closing the opening and closing piece 10.

[0034] Reference Figures 2-3 In a preferred embodiment, a Velcro 5 14 is fixedly connected to the left side of the sleeve 1. The Velcro 5 14 is located outside the operating opening 11. The left side of the Velcro 5 14 is adhesively connected to the right side of the Velcro 4 13. When the Velcro 4 13 is used with the opening and closing piece 10, it provides a force-applying medium for the Velcro 4 13 to adhere to the sleeve 1, avoiding the situation where the Velcro 4 13 is difficult to effectively close and adhere to the opening and closing piece 10 and the operating opening 11. Therefore, the adhesive positioning effect of the Velcro 4 13 is improved. A Velcro 6 15 is embedded and connected to the left side of the sleeve 1. The Velcro 6 15 is located on top of the Velcro 4 13. When the Velcro 6 15 is used with the Velcro 4 13, it provides a medium for the Velcro 4 13 to be opened and for the opening and closing piece 10 to adhere and position to the sleeve 1, avoiding the situation where the opening and closing piece 10 is difficult to open and position. Therefore, the ease of opening and positioning of the opening and closing piece 10 is improved.

[0035] Reference Figure 4In a preferred embodiment, limiting rings 16 are movably connected to both the top and bottom of the sleeve body 1 surface. Several limiting rings 16 are provided, and these rings are evenly distributed in an arc shape. When the elastic band 2 is used with the sleeve body 1, the position of the wrapped elastic band 2 is limited, preventing positional deviation during operation and thus improving the stability of the elastic band 2. Connecting sleeves 17 are fixedly connected to both the top and bottom of the sleeve body 1 surface. Several connecting sleeves 17 are provided, and these sleeves are evenly distributed in an arc shape. The inner side of the limiting rings 16 is located inside the connecting sleeves 17. When the limiting rings 16 are used with the elastic band 2, they provide a medium for applying force to the sleeve body 1, preventing the limiting rings 16 from being unable to connect with the sleeve body 1 and apply limiting force to the elastic band 2. This improves the connection effect between the limiting rings 16 and the sleeve body 1.

[0036] Specifically, the working process or principle of this protective sleeve applicable to PICC placement is as follows: In use, first, hold the sleeve 1 and place it over the outside of the PICC catheter in the patient's arm. Then, according to the actual arm circumference of the patient, hold the fixing strap 3 and move the elastic band 2 through the limiting ring 16 to wrap around the outside of the sleeve 1. At this time, the limiting ring 16, in conjunction with the connecting sleeve 17, wraps and limits the elastic band 2 and the sleeve 1, and pulls the fixing strap 3 to apply tension to the elastic band 2, so that the two sides of the inner side of the sleeve 1 fit snugly against the patient's arm. During this process, the Velcro 6 moves with the fixing strap 3. When the patient's arm circumference is too large and the fixing strap 3 cannot wrap around the sleeve 1 once, Velcro 6 and Velcro 7 are attached. When the patient's arm circumference is too small and the fixing strap 3 can wrap around the sleeve 1 once, the adhesive strip and Velcro 8 are attached. The fixing strap 3 is used to wrap and position the elastic band 2, so that the elastic band 2 stably wraps and tightens the sleeve 1 around the outside of the PICC catheter in the patient's arm, protecting the PICC catheter and ensuring the wearability of the sleeve 1. When medical staff need to perform medical procedures on the patient through the PICC catheter in the patient's arm, they hold the force plate 12. Apply a lifting force to the opening and closing piece 10 to separate the hook and loop fasteners 13 and 14, opening the operating port 11. At this time, the opening and closing strip 9 flexibly connects the opened opening and closing piece 10 to the sleeve 1. Then, hold the opened opening and closing piece 10 and rotate the hook and loop fasteners 13 to contact the hook and loop fasteners 15, thus adhesively positioning the opened opening and closing piece 10 to the sleeve 1. Subsequently, treatment can be performed on the patient through the inserted PICC catheter. If the inserted PICC catheter requires long-term infusion after being connected to an external catheter, the opening and closing piece can be rotated again. 10 separates hook and loop fastener 4 13 from hook and loop fastener 6 15, and then the opening and closing piece 10 moves hook and loop fastener 4 13 to hook and loop fastener 5 14 to stick together, closing the operating port 11. At this time, the hook and loop fastener 4 13 and hook and loop fastener 5 14 can perform the sticking and positioning work on the catheter connected to the inserted PICC catheter, ensuring the protective effect of the sleeve 1 on the inserted PICC catheter during the use of the inserted PICC catheter. Since hook and loop fastener 1 and hook and loop fastener 4 are hook and loop fastener ...

[0037] It should be noted that the sleeve 1 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
