Abstract
Description
Technical Field
[0001] This utility model relates to a medical device, specifically a protective sleeve for intravenous catheter placement. Background Technology
[0002] Intravenous catheterization refers to the surgical insertion of a catheter (usually a soft plastic tube) into a vein to establish a pathway for drug injection, nutritional infusion, blood collection, blood transfusion, or other medical procedures. Intravenous catheterization is widely used in clinical treatment, especially in cases requiring long-term or repeated drug administration, often as a necessary medical procedure. Intravenous catheter protective sleeves are medical devices used to protect intravenous catheters (usually venous catheters, central venous catheters, peripheral venous catheters, etc.) from external contamination, damage, or misoperation. They are primarily used in clinical practice to ensure the insertion site remains sterile, prevent infection, and provide a degree of physical protection during intravenous catheterization treatment.
[0003] Currently, there are various types of nursing intravenous catheter protective sleeves, such as breathable and waterproof types. However, nursing intravenous catheter protective sleeves generally cannot achieve both waterproof and breathable effects at the same time. When patients need to clean their bodies with intravenous catheters in place, they need to wear waterproof protective sleeves. However, waterproof protective sleeves have poor breathability, which affects the wearing experience during long-term wear. Therefore, it is necessary to replace them with breathable protective sleeves. Changing between different types of protective sleeves increases the workload and affects the effectiveness of use. Utility Model Content
[0004] The purpose of this invention is to provide a protective sleeve for intravenous catheter placement to solve the problems mentioned in the background art.

[0008] The rotating cylinder rotates between the two protective shells to adjust and control the orientation of the sealing mechanism and the venting mechanism. When the sealing mechanism slides to one side of the rotating cylinder, the venting mechanism is exposed. When the sealing mechanism slides to the other side of the rotating cylinder, the venting mechanism is retracted into the rotating cylinder.
[0009] The above-mentioned nursing intravenous catheter protective sleeve: the rotating cylinder is made of transparent acrylic material, and rotating rings are fixedly connected to both ends of the rotating cylinder, and the rotating rings are slidably connected in the rotating groove;

The second abutting edge is abutting against the cover plate on the side opposite to the first abutting edge. The breathable mesh panel on the side opposite to the second abutting edge is abutting against the first abutting edge.
[0016] The above-mentioned nursing intravenous catheter protective sleeve: the limiting mechanism includes a sliding frame, a sliding block slidably connected in the sliding frame, and a positioning strip fixedly connected to the sliding block;
[0017] The sliding frame is fixedly connected to the rotating cylinder on one side of the window. The sliding frame has a threaded hole, which is threadedly connected to the screw. A knob is fixedly connected to one end of the top of the screw, and the other end of the screw is rotatably connected to the sliding block.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0037] Please see Figures 1-12In this embodiment of the utility model, a nursing intravenous catheter protective sleeve includes two symmetrically arranged protective shells 1 and a connecting rod 3 connected between the two protective shells 1. A rotating groove 2 is provided on each side of the two protective shells 1, and a breathable sealing structure is provided between the two protective shells 1. The breathable sealing structure rotates and abuts against the connecting rod 3.
[0038] The breathable sealing structure includes a rotating cylinder 10 that rotates between the two protective housings 1, a sealing mechanism that is slidably connected to the rotating cylinder 10, and a breathable mechanism that is connected to the sealing mechanism and slidably connected to the rotating cylinder 10.
[0039] The rotating cylinder 10 rotates between the two protective housings 1 to adjust and control the orientation of the sealing mechanism and the venting mechanism. When the sealing mechanism slides to one side of the rotating cylinder 10, the venting mechanism is exposed. When the sealing mechanism slides to the other side of the rotating cylinder 10, the venting mechanism is retracted into the rotating cylinder 10.
[0040] In this embodiment, the connecting rod 3 is used to fix the two protective shells 1 together. The rotating groove 2 provided on the two protective shells 1 is used for the rotating connection of the rotating cylinder 10. The rotating cylinder 10 is provided with a breathable sealing structure, which is composed of a sealing mechanism and a ventilating mechanism. When the patient wears the protective cover to take a shower, the sealing mechanism can achieve the practical effect of sealing and waterproofing the protective cover, which can prevent the skin at the intravenous catheter insertion site from getting wet and improve the waterproof effect. By sliding the sealing mechanism to one side, the ventilating mechanism can be exposed, and the protective cover can achieve the effect of ventilation, avoiding the problem of discomfort caused by the long-term sealing of the protective cover. By sliding the sealing mechanism to the other side, the ventilating mechanism can be simultaneously inserted into the rotating cylinder 10. At this time, the notch at the rotating cylinder 10 is open, which facilitates the medical staff to check or operate the intravenous catheter, achieving a multi-functional use effect and improving practicality.
[0041] As a further embodiment of this utility model, the rotating cylinder 10 is made of transparent acrylic material, and rotating rings 11 are fixedly connected to both ends of the rotating cylinder 10. The rotating rings 11 are slidably connected in the rotating groove 2.
[0042] The rotating cylinder 10 has a window 12, and a storage groove 13 is provided on both sides of the rotating cylinder 10. The storage groove 13 is slidably connected to the sealing mechanism, and a limit mechanism is provided on both sides of the rotating cylinder 10.
[0043] In this embodiment, the rotating cylinder 10 made of transparent acrylic material allows medical staff to easily observe the intravenous catheter protected inside the protective sleeve when the patient is wearing the protective sleeve, improving the convenience of observation. The window 12 on the rotating cylinder 10 allows medical staff to perform operations such as inspection of the intravenous catheter without removing the protective sleeve, improving the convenience of operation. The rotating rings 11 at both ends of the rotating cylinder 10 are rotatably connected in the rotating groove 2, satisfying the rotational connection effect of the rotating cylinder 10 between the two protective shells 1 and ensuring the overall connectivity.
[0044] As a further embodiment of the present invention, the sealing mechanism includes a cover plate 20 slidably connected in the storage groove 13 and a plurality of first arc-shaped springs 22 disposed on one side of the cover plate 20.
[0045] The cover plate 20 is integrally formed with a first abutting edge 21 on one side of the first arc spring 22. The first abutting edge 21 is connected to one end of the plurality of first arc springs 22, and the other end of the first arc spring 22 is fixed to the inner wall of the storage groove 13.
[0046] The cover plate 20 is provided with anti-slip texture 23, and the cover plate 20 on both sides of the anti-slip texture 23 is provided with a first indicator head 24 and a second indicator head 25 respectively. The first contact edge 21 is connected to the ventilation mechanism, and the anti-slip texture 23 is connected to the limiting mechanism.
[0047] In this embodiment, the first contact edge 21 integrally formed on one side of the cover plate 20 is connected to one end of a plurality of first arc-shaped springs 22. When the cover plate 20 moves toward the first arc-shaped springs 22 on the rotating cylinder 10, the first arc-shaped springs 22 are compressed and contracted to maintain a rebound force. The opening function when moving in different directions can be known through the first indicator head 24 and the second indicator head 25 provided on the cover plate 20. When the cover plate 20 slides open toward the first indicator head 24, the ventilation mechanism is exposed. When the cover plate 20 slides open toward the second indicator head 25, the sealing mechanism is also retracted into the rotating cylinder 10. The limiting mechanism can limit the movement of the cover plate 20 to prevent the cover plate 20 from resetting under the rebound force of the first arc-shaped springs 22, thus meeting the usage requirements.
[0048] As a further embodiment of this utility model, the breathable mechanism includes a breathable mesh plate 26 slidably connected in the storage groove 13 on the other side and a plurality of second arc-shaped springs 28 disposed on one side of the breathable mesh plate 26.
[0049] One side of the breathable mesh panel 26 is integrally formed with a second abutting edge 27. The second abutting edge 27 is connected to one end of a plurality of second arc-shaped springs 28. The other end of the second arc-shaped springs 28 is fixed to the inner wall of the storage groove 13. The second abutting edge 27 is abutting the cover plate 20 on the side opposite to the first abutting edge 21. The breathable mesh panel 26 on the side opposite to the second abutting edge 27 is abutting the first abutting edge 21.
[0050] In this embodiment, the second contact edge 27, integrally formed on one side of the breathable mesh plate 26, abuts against one end of a plurality of second arc-shaped springs 28. When the breathable mesh plate 26 slides towards the second arc-shaped springs 28 on the rotating cylinder 10, the second arc-shaped springs 28 are compressed and retain their rebound force. Since the second contact edge 27 abuts against one side of the cover plate 20 and the first contact edge 21 abuts against one side of the breathable mesh plate 26, when the cover plate 20 moves towards the second contact edge 27, the breathable mesh plate 26 will be drawn into the rotating cylinder 10 along with the cover plate 20 when the cover plate 20 is retracted into the rotating cylinder 10. Since both the first contact edge 21 and the second contact edge 27 abut against a plurality of first arc-shaped springs 22 and second arc-shaped springs 28, and the first arc-shaped springs 22 and second arc-shaped springs 28 are in contact with each other, the breathable mesh plate 26 will be drawn into the rotating cylinder 10 along with the cover plate 20. The other end of the spring 28 is fixedly connected to the inner wall of the storage slot 13. Therefore, when the cover plate 20 carrying the breathable mesh plate 26 is retracted into the rotating cylinder 10, the second arc spring 28 will not be stretched. Similarly, when the cover plate 20 is retracted into the rotating cylinder 10 alone, the first arc spring 22 will not be stretched. When the cover plate 20 is sealed at the window 12, the protective cover is in a sealed state, which can achieve the effect of waterproofing the patient when showering. When it is necessary to allow ventilation at the intravenous catheterization site, the cover plate 20 can be slid open to expose the ventilation mechanism, which can achieve the ventilation effect. When the cover plate 20 carrying the breathable mesh plate 26 is retracted into the rotating cylinder 10, the window 12 at the rotating cylinder 10 is open, which makes it convenient for medical staff to perform intravenous catheterization examinations without removing the protective cover.
[0051] As a further embodiment of this utility model, the limiting mechanism includes a sliding frame 14, a sliding block 18 slidably connected within the sliding frame 14, and a positioning strip 19 fixedly connected to the sliding block 18.
[0052] The sliding frame 14 is fixedly connected to the rotating cylinder 10 on one side of the window 12. The sliding frame 14 has a threaded hole 15, which is threadedly connected to the screw 16. A knob 17 is fixedly connected to one end of the top of the screw 16, and the other end of the screw 16 is rotatably connected to the sliding block 18.
[0053] The positioning strip 19 is engaged with the anti-slip texture 23.
[0054] In this embodiment, when the cover plate 20 moves to any side of the rotating cylinder 10, the knob 17, which controls the direction of movement of the cover plate 20, is rotated. The knob 17 drives the screw 16 to rotate. Since one end of the screw 16 is rotatably connected to the sliding block 18, and the sliding block 18 is slidably connected to the sliding frame 14, the sliding block 18 can slide vertically within the sliding frame 14, causing the positioning strip 19 to abut against the anti-slip texture 23. This achieves the abutment positioning of the cover plate 20, preventing the cover plate 20 from shifting and achieving the positioning effect.
[0055] As a further embodiment of this utility model, a silicone sleeve 4 is provided at one end of the protective shell 1, and a plurality of silicone tightening edges 5 are provided on the outer wall of the protective shell 1 of the silicone sleeve 4. A stretch band 7 is provided on one of the silicone tightening edges 5, and a hook and loop fastener 8 is provided on one side of the end of the stretch band 7. A hook and loop fastener 6 that is attached to the hook and loop fastener 8 is provided on the plurality of silicone tightening edges 5 located on one side of the hook and loop fastener 8.
[0056] In this embodiment, by setting a silicone sleeve 4 on the protective shell 1, the protective shell 1 is placed on the patient's arm. Due to the different arm circumferences of patients, the silicone sleeve 4 may not fit tightly on the patient's arm. By pulling the stretch band 7, the hook and loop fastener 8 on the stretch band 7 is attached to the corresponding hook and loop fastener 6, which can first tighten the silicone sleeve 4, thereby enabling the protective sleeve to be worn on the patient's arm and improving the fit and sealing effect between the protective sleeve and the patient's arm.
[0057] As a further embodiment of this utility model, an elastic mesh cylinder 9 is provided between the two protective shells 1. One end of the elastic mesh cylinder 9 is fixedly connected to the inner wall of the end of one of the protective shells 1, and the other end of the elastic mesh cylinder 9 is fixedly connected to the inner wall of the end of the other protective shell 1.
[0058] In this embodiment, an elastic mesh cylinder 9 is provided between the two protective shells 1. When the protective shell 1 is fitted onto the patient's arm at the site of the intravenous catheter insertion, the elastic mesh cylinder 9 will tighten the intravenous catheter, making the intravenous catheter fit snugly against the patient's arm, thus protecting the intravenous catheter and preventing it from slipping. When the sealing mechanism on the rotating cylinder 10 is opened, exposing the ventilation mechanism, the elastic mesh cylinder 9, being a breathable mesh cylinder, can achieve a ventilation effect, meeting the usage requirements.
[0059] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
