Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a sterile single-laying device for catheter placement. Background Art
[0002] Patients can avoid direct contact between drugs and veins in the arm by inserting PICC (Peripherally Inserted Central Catheter) / arm port / chest port / CVC (central venous catheter), speed up the dilution of drugs, reduce drug stimulation to blood vessels, reduce venous puncture, and relieve pain for patients. During the insertion of PICC / arm port / chest port / CVC, in order to prevent infection and achieve the maximum sterile barrier, a sterile sheet needs to be covered on the patient's head, and the sterile sheet completely covers the patient's face.
[0003] However, when the sterile sheet is directly placed on the patient's face, the patient will feel nervous and have difficulty breathing, especially for seriously ill patients who are receiving oxygen or ventilators, which makes the situation worse. For patients with claustrophobia, these patients may even feel fear. Some patients even refuse to cover their faces with the sterile sheet due to local customs, which affects the subsequent catheterization process. Therefore, when PICC / arm port / chest wall port / CVC is placed clinically, that is, when performing catheterization surgery, because the sheet is placed on the patient's face, medical communication is difficult, and the patient feels stuffy during the catheterization process, which requires treatment, wasting time; and some patients do not cooperate during the catheterization process and remove the sheet during the catheterization process. At this time, disinfection and sterilization barrier must be re-established, which prolongs the catheterization time; some patients even refuse to be intubated after the sheet is placed, wasting medical supplies and manpower; and when the sheet is contaminated or removed during the catheterization, there is a risk of infection. Once the PICC / arm port / chest wall port / CVC catheter is infected, the tube may be removed in mild cases, and sepsis or even death may occur in severe cases.
[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0028] The utility model provides a sterile single-laying device for catheter placement. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0029] like Figure 1 and Figure 2As shown, a sterile sheet laying device for catheter placement is used to separate the patient's head from the sterile sheet to prevent the patient from lifting the sterile sheet off or contaminating it, thereby ensuring that the catheter placement process is not contaminated. The sterile sheet laying device for catheter placement includes a fixing frame 1, an adjusting frame 2, and a shielding member 3. The shielding member 3 includes two fixing rods 11 spaced apart along a first direction, wherein the first direction is longitudinal. When laying the sterile sheet, the sterile sheet covers the fixing rods 11, and the fixing rods 11 provide support for the sterile sheet, thereby separating the sterile sheet from the patient's face. The adjusting frame 2 is rotatably mounted on both ends of the fixing rods 11 in a second direction, wherein the second direction is transverse, and the second direction is perpendicular to the first direction, thereby forming four legs of the sterile sheet laying device for catheter placement, which are supported by the adjusting frame 2 so that the sterile sheet maintains a certain distance from the patient's face when it is covered on the fixing rods 11. distance; in addition, the width of the bottom of the sterile sheet laying device for catheter placement is adjusted by rotating the adjustment frame 2 around the two ends of the fixed rod 11, that is, the spacing in the second direction is adjusted. Because the head widths of different patients are different, when using the sterile sheet laying device for catheter placement to separate the sterile sheet from the patient's face, the sterile sheet laying device for catheter placement needs to be placed on top of the patient's head, and the bottom of the sterile sheet laying device for catheter placement is located on both sides of the patient's head. Therefore, it is necessary to match different patients by adjusting the width of the bottom of the sterile sheet laying device for catheter placement, so that the sterile sheet laying device for catheter placement can match all patients. The shielding member 3 is slidably installed along the second direction between the fixed rods 11 on both sides. Since there is a gap between the fixed rods 11, if the shielding member 3 is not set between the fixed rods 11, then when the sterile sheet is placed on the fixed rods 11, the sterile sheet will sink into the gap between the fixed rods 11, causing the sterile sheet to collapse in the direction of the patient's face, resulting in contact between the sterile sheet and the patient's face, affecting the patient's breathing and making the patient feel uncomfortable during the catheterization process. At the same time, since the shielding member 3 adopts a sliding design, when the sterile sheet laying device for catheterization is not in use but in a storage state, the shielding member 3 can be folded and contracted by sliding the shielding member 3 to prevent other objects from hitting the shielding member 3 and causing the sterile sheet laying device for catheterization to be damaged.
[0030] In order to allow the shielding member 3 to slide along the fixed rod 11, first slide grooves 111 are provided on opposite sides of the fixed rod 11, and the shielding member 3 is slidably installed in the first slide grooves 111. At the same time, in order to allow the shielding member 3 to be retracted and expanded, that is, when the sterile sheet laying device for intubation is required to support the laid sterile sheet, the shielding member 3 is fully expanded to ensure that the interval between the fixed rods 11 is fully filled to prevent the sterile sheet from falling from the interval between the fixed rods 11; and when the sterile sheet laying device for intubation is not in use but in a storage state, the shielding member 3 is in a retracted state to prevent other objects from falling on the shielding member 3 and damaging the sterile sheet supporting device. In this embodiment, the shielding member 3 includes a shielding cloth 31 and a plurality of adjustment rods 32, the shielding cloth 31 is installed between the adjustment rods 32, and the two ends of the adjustment rods 32 are slidably installed in the first slide grooves 111. In this embodiment, the shielding member 3 includes two adjustment rods 32 and a shielding cloth 31. The adjustment rods 32 are arranged on both sides of the shielding member 3, and the shielding cloth 31 is installed between the two adjustment rods 32. The adjustment rods 32 are slidably installed in the first slide groove 111, so that the shielding member 3 can slide along the fixed rod 11, and in order to achieve the functions of contraction and expansion, the shielding cloth 31 adopts a foldable design. That is, when the sterile sheet laying device for intubation supports the sterile sheet covering the upper part, the two adjustment rods 32 slide in opposite directions, so that the shielding cloth 31 in the folded state is fully expanded, so as to fill the gap between the fixed rods 11, and prevent the sterile sheet from falling from the gap between the fixed rods 11 and causing the sterile sheet to contact the patient's face, so as to improve the patient's comfort during intubation. When the sterile sheet laying device for catheter placement is not in use but in a storage state, the two adjustment rods 32 approach each other, so that the shielding cloth 31 in the unfolded state is folded, reducing the area of the shielding member 3, and preventing the sterile sheet laying device for catheter placement from being hit by other objects when it is stored, thereby preventing the sterile sheet laying device for catheter placement from being damaged.
[0031] Further, when the adjusting rod 32 slides in the first slide groove 111, in order to prevent the adjusting rod 32 from sliding out of the fixing rod 11 from the first slide groove 111, it is necessary to limit the sliding range of the adjusting rod 32. The fixing frame 1 also includes a first limiting member 12, which is installed in the first slide groove 111 and is used to limit the sliding of the adjusting rod 32. Specifically, the first limiting member 12 includes a first limiting rod 121 and a first limiting block 122. In this embodiment, two first limiting rods 121 are provided, which are respectively installed at both ends of the fixing rod 11. Figure 1As shown, the sliding range of the adjusting rod 32 is limited by two first limiting rods 121 to prevent the adjusting rod 32 from sliding out of the first sliding groove 111 . Meanwhile, the first limiting rods 121 also play a role in strengthening the structure to prevent the fixing frame 1 from bending and deformation. The first limit block 122 is slidably arranged in the first slide groove 111, and the sliding range of the adjustment rod 32 is further limited by the first limit block 122. At the same time, when the shielding cloth 31 is fully unfolded, the adjustment rod 32 is close to the first limit rod 121. At this time, the first limit block 122 is used to separate the first limit rod 121 and the adjustment rod 32, so that when the sterile sheet laying device for catheter placement needs to be stored later, the shielding cloth 31 can be folded by pushing the adjustment rod 32. In addition, the first limit block 122 is interference fit with the first slide groove 111, that is, a certain force is required to push the first limit block 122, thereby avoiding accidental pushing of the first limit block 122 to cause the adjustment rod 32 to slide with the limit block, avoid affecting the shielding range of the shielding cloth 31, and prevent the sterile sheet from falling from the gap between the fixed rods 11 and directly contacting the patient's face due to the sudden change in the shielding range of the shielding cloth 31.
[0032] In order to make the sterile single-sheet laying device for catheter placement suitable for different patients, it is necessary to adjust the width of the bottom of the sterile single-sheet laying device for catheter placement. Before placing the sterile single-sheet laying device for catheter placement, first adjust the appropriate width according to the conditions of different patients, and then place the sterile single-sheet laying device for catheter placement above the patient's head. In this embodiment, the width of the bottom of the sterile single-sheet laying device for catheter placement is adjusted by rotating the adjustment frame 2. In this embodiment, in order to allow the adjustment frame 2 to rotate, rotation holes 112 are provided at both ends of the fixed rod 11. The adjustment frame 2 is rotatably mounted on the rotation holes 112. Therefore, when it is necessary to adjust the width of the bottom of the sterile single-sheet laying device for catheter placement, the width is adjusted by rotating the adjustment frame 2 around the rotation hole 112.
[0033] Specifically, the adjusting frame 2 includes a plurality of rotating shafts 21 and a plurality of rotating rods 22, each rotating shaft 21 passes through a rotating hole 112, and each rotating rod 22 is rotatably mounted on a rotating shaft 21. In the present embodiment, the adjusting frame 2 includes four rotating rods 22 and four rotating shafts 21, wherein two rotating shafts 21 and rotating rods 22 are respectively mounted at both ends of a fixed rod 11, and the other two rotating shafts 21 and rotating rods 22 are respectively mounted at both ends of another fixed rod 11. Therefore, when it is necessary to adjust the bottom width of the sterile single laying device for catheter placement, the rotating rod 22 is turned left or right, and the bottom width of the sterile single laying device for catheter placement changes accordingly. Therefore, when the patient's head is narrow, the bottom width needs to be reduced. At this time, the rotating rod 22 is turned so that the two relative rotating rods 22 rotate toward each other, thereby reducing the bottom width of the sterile single-laying device for catheter placement; when the patient's head is wide, the bottom width needs to be increased. At this time, the rotating rod 22 is turned so that the two relative rotating rods 22 rotate away from each other, thereby expanding the bottom width of the sterile single-laying device for catheter placement.
[0034] At the same time, in order to ensure that the height of the sterile sheet laying device for catheter placement is consistent after the bottom width is adjusted, or to adjust the height of the sterile sheet laying device for catheter placement according to the head size of different patients, the sterile sheet laying device for catheter placement can be matched with different patients, avoiding the contact between the sterile sheet and the patient's face, and improving the patient's comfort during the catheterization process. Therefore, the adjustment frame 2 also includes a plurality of slide bars 23, each of which is slidably mounted on a rotating rod 22, and the height of the sterile sheet laying device for catheter placement is adjusted by sliding the slide bar 23 on the rotating rod 22. In this embodiment, the adjustment frame 2 includes four slide bars 23, each of which is slidably mounted on a rotating rod 22. Therefore, when the rotating rod 22 is turned to reduce the bottom width of the sterile single laying device for catheter placement, the height of the sterile single laying device for catheter placement will gradually increase. In order to maintain the height consistency of the sterile single laying device for catheter placement, the slide bar 23 is allowed to slide upward along the rotating rod 22 to gradually reduce the height of the sterile single support device, so as to keep the height of the sterile single laying device for catheter placement consistent with the height before adjusting the bottom width; and when the rotating rod 22 is turned to expand the bottom width of the sterile single laying device for catheter placement, the height of the sterile single laying device for catheter placement will gradually decrease. In order to maintain the height consistency of the sterile single laying device for catheter placement, the slide bar 23 is allowed to slide downward along the rotating rod 22 to gradually increase the height of the sterile single support device, so as to keep the height of the sterile single laying device for catheter placement consistent with the height before adjusting the bottom width. In order to allow the slide bar 23 to slide along the rotating rod 22, a second slide groove 221 is provided in the rotating rod 22, and the second slide groove 221 is provided on opposite sides of the rotating rod 22. At this time, the slide bar 23 is slidably installed in the second slide groove 221, and the slide bar 23 and the second slide groove 221 are interference fit. Only when a certain force is applied can the slide bar 23 be pushed to slide in the second slide groove 221, so that the slide bar 23 can be fixed at a certain position in the second slide groove 221 without the action of external force, so as to keep the height of the sterile sheet laying device for catheterization at a certain level, so as to avoid sudden sliding of the slide bar 23, which may cause the sterile sheet to directly contact the patient's face and affect the patient's catheterization process.
[0035] Similarly, in order to limit the sliding range of the slide bar 23 and prevent the slide bar 23 from sliding out of the second slide groove 221 and the rotating rod 22, thereby causing the sterile single laying device for catheter placement to be destroyed, the adjustment frame 2 also includes a second limit member 222, and the second limit member 222 is installed in the second slide groove 221. In the present embodiment, the second limit member 222 is installed at both ends of the second slide groove 221. When the slide bar 23 slides toward the two ends of the second slide groove 221, the second limit member 222 blocks the slide bar 23 from sliding further. Therefore, the slide bar 23 cannot slide out of the second slide groove 221 under the obstruction of the second limit member 222, thereby preventing the slide bar 23 from sliding out of the slide bar. In addition, in order to strengthen the structural strength of the adjustment frame 2 and prevent the adjustment frame 2 from deforming under the action of external force and causing the sterile catheter sheet to be damaged, the adjustment frame 2 also includes a plurality of reinforcing rods 24, which are installed between the two relative slide bars 23 to keep the interval between the two relative slide bars 23 unchanged. Therefore, in this embodiment, the adjustment frame 2 includes two reinforcing rods 24, each of which is installed between the two relative slide bars 23. At the same time, the setting of the reinforcing rods 24 also facilitates the sliding of the slide bar 23, and the slide bar 23 can be slid by toggling the reinforcing rods 24.
[0036] To summarize, when it is necessary to use the sterile sheet laying device for catheter placement in this embodiment to separate the sterile sheet from the patient's face, first slide the adjustment rod 32 to make the adjustment rod 32 slide in the opposite direction to unfold the covering cloth 31, then turn the rotating rod 22 to adjust the bottom width of the sterile sheet laying device for catheter placement, and at the same time slide the slide bar 23 to adjust the height of the sterile sheet laying device for catheter placement. After the adjustment is completed, the sterile sheet laying device for catheter placement is placed above the patient's head. After the placement is completed, the sterile sheet is covered on the covering member 3 to separate the sterile sheet from the patient's face.

For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
