Description

Technical Field

[0001] The utility model belongs to the technical field of clinical nursing, and in particular relates to a peripheral venous central catheter dressing support. Background Art

[0002] Peripherally inserted central catheter (PICC) is a technique that uses a catheter to puncture a vein in the arm so that the catheter reaches the large vein area close to the heart. This catheter is often called a peripheral venous central catheter in clinical practice. The dressing must be changed within the first 24 hours after the peripheral venous central catheter is inserted. If the wound heals well and there is no infection or bleeding, the dressing should be changed every 7 days. If the wound dressing is loose or damp, it should be changed at any time.

[0003] According to the operational standards for catheter placement and dressing changes, the width of the dressing used is generally at least 10 cm. After removing the old dressing, first clean the residual glue on the skin, and then disinfect the area around the puncture site. The method for removing the residual glue on the skin is usually to use a cotton swab dipped in alcohol to apply it on the patient's skin, and the method for disinfecting the skin near the puncture point is to use a cotton swab dipped in disinfectant to apply it. The diameter of the disinfection range is generally about 15 cm (centered on the puncture point), and it needs to be disinfected several times. The required operating area is relatively large, and the process is relatively delicate and cumbersome. At present, when changing dressings, the patient usually places his arm directly on the bedside or table for the nursing staff to operate. Therefore, the nursing staff needs to turn or lift the patient's arm with one hand and perform corresponding operations with the other hand, which is inconvenient. Therefore, the prior art provides some corresponding dressing change auxiliary devices, such as the Chinese utility model patents with publication numbers CN209286012U and CN215229648U. Although such auxiliary devices can improve the convenience of the aforementioned dressing change operation, they are relatively large in overall size and have many unnecessary structures, making them less flexible to use and inconvenient for nursing staff to carry and use in various wards.

[0004] The technical problem to be solved by the utility model is to provide a peripheral venous central catheter dressing change bracket which improves the operating convenience and efficiency, is foldable as a whole, is convenient for nursing staff to carry together with other instruments or operating supplies and use in various wards, and is labor-saving and more flexible.

[0005] The utility model includes two support rods 1 and two support rods 2, the middle parts of the two support rods 1 are hinged to the middle parts of the two support rods 2 to form two fork-shaped structures, and a supporting rod is respectively arranged between the upper ends of the two support rods 1 and between the upper ends of the two support rods 2, and the two supporting rods are used to support the patient's arms;

[0006] It also includes a telescopic mechanism, which is used to adjust the angle between the first support rod and the second support rod in the two fork-shaped structures.

[0007] Furthermore, the two supporting rods are both arc-shaped.

[0008] Furthermore, the two supporting rods are correspondingly hingedly arranged between the upper ends of the two support rods one and between the upper ends of the two support rods two.

[0009] Furthermore, the surfaces of the two supporting rods are both provided with soft pads.

[0010] Furthermore, a connecting rod is respectively arranged between the lower ends of the two first supporting rods and between the lower ends of the two second supporting rods.

[0011] Furthermore, the telescopic mechanism is arranged between two connecting rods, and the two connecting rods are correspondingly hinged between the lower ends of the two support rods one and between the lower ends of the two support rods two, or the two ends of the telescopic mechanism are correspondingly hinged with the two connecting rods.

[0012] Furthermore, the telescopic mechanism is arranged between one of the connecting rods and a supporting rod located above the connecting rod.

[0013] Furthermore, the telescopic mechanism includes an outer rod and an inner rod inserted into the outer rod, and a locking bolt for fixing the inner rod is arranged on the side of the outer rod.

[0014] Furthermore, the lower ends of the two support rods 1 and the lower ends of the two support rods 2 are both arc-shaped.

[0015] Furthermore, the two support rods 1, the two support rods 2 and the two supporting rods are all made of stainless steel and have a hollow structure.

[0016] The beneficial effect of the utility model is that, based on the setting mode of the two supporting rods, the two supporting rods can be used to support the patient's arm and can also be used as a connecting piece between the two fork-shaped structures, so that the two fork-shaped structures can be driven to extend simultaneously through a telescopic mechanism. The two fork-shaped structures are unfolded at a certain angle by the telescopic mechanism, and a certain distance is opened between the two supporting rods. The arm is supported by the two supporting rods, and the area between the two supporting rods forms an exposed space for the puncture position on the arm. The puncture position and the surrounding skin are in a suspended state, and the puncture position and the surrounding skin can be completely exposed without the need for the nursing staff to manually flip or lift the patient's arm. The nursing staff can directly clean and disinfect the skin around the puncture position in an all-round manner, and because the patient's arm is raised when the utility model is used, the degree of bending of the nursing staff during operation is reduced, the nursing staff's work intensity is reduced, and the dressing change operation is more labor-saving, and the convenience and efficiency of the operation are improved. And through the telescopic degree of the telescopic mechanism, the overall height of the dressing change bracket can also be adjusted by adjusting the degree of expansion of the two fork-shaped structures to adapt to the height and operation habits of different nursing staff.

[0017] The utility model is easy to use and has a simpler overall structure. After use, the utility model can be folded as a whole through the telescopic mechanism, requiring smaller storage space, being light in weight and convenient to carry, and can be convenient for nursing staff to carry it together with other instruments or operating supplies and use in various wards. There is no need to independently configure a dressing change stand in each ward, which is labor-saving and more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 3As shown, the utility model provides a peripheral venous central catheter dressing stand, including two support rods 1 and two support rods 2, the middle parts of the two support rods 1 are hinged to the middle parts of the two support rods 2, that is, the middle part of one support rod 1 is hinged to the middle part of one support rod 2, and the middle part of the other support rod 1 is hinged to the middle part of the other support rod 2, so as to form two fork-shaped structures, and a supporting rod 3 is respectively arranged between the upper ends of the two support rods 1 and between the upper ends of the two support rods 2, that is, there are two supporting rods 3 in total, and the two supporting rods 3 are used to support the patient's arms. The utility model also includes a telescopic mechanism 4, and the telescopic mechanism 4 is used to adjust the angle between the support rod 1 and the support rod 2 in the two fork-shaped structures, that is, to adjust the degree of expansion of the two fork-shaped structures so that they are as follows Figure 2 Expand at a certain angle as shown or as Figure 3 The utility model can be folded as shown, and the overall height of the utility model when in use can be adjusted thereby.

[0023] The peripheral venous central catheter dressing stand provided by the utility model is based on the arrangement of two supporting rods 3. The two supporting rods 3 can be used to support the patient's arm and can also be used as a connecting piece between two fork-shaped structures, so that the two fork-shaped structures can be driven to extend simultaneously through a telescopic mechanism 4. When in use, the whole is placed on a bed or table, with the two supporting rods 3 located at the top, and the lower ends of the two supporting rods 1 and the two supporting rods 2 are used to support the whole. Figure 2 As shown, the two fork structures are unfolded at a certain angle by the telescopic mechanism 4, and a certain distance is opened between the two supporting rods 3. The two supporting rods 3 are used to support the arm, and the puncture position on the arm is located between the two supporting rods 3. The area between the two supporting rods forms an exposed space for the puncture position on the arm, and the puncture position and the surrounding skin are suspended. The puncture position and the surrounding skin can be completely exposed without the need for the nursing staff to manually flip or lift the patient's arm. The nursing staff can directly clean and disinfect the skin around the puncture position in an all-round way. When the utility model is used, the patient's arm is raised, which reduces the degree of bending of the nursing staff during operation, reduces the nursing staff's work intensity, makes the dressing change operation more labor-saving, and improves the convenience and efficiency of the operation. And through the telescopic degree of the telescopic mechanism 4, the overall height can also be adjusted by adjusting the degree of expansion of the two fork structures to adapt to the height and operating habits of different nursing staff.

[0024] The utility model is easy to use and has a simpler overall structure. Based on the structural arrangement of the utility model, after use, the utility model can be folded as a whole through the telescopic mechanism 4 to form a Figure 3In the state shown, the required storage space is smaller, the weight is light and it is easy to carry, so that nursing staff can carry it together with other equipment or operating supplies and use it in various wards. There is no need to independently configure a dressing change stand in each ward, which saves effort and is more flexible.

[0025] In other embodiments of the present invention, the two support rods 3 may be straight. In a preferred embodiment of the present invention, the two support rods 3 are both arc-shaped. Figure 1 As shown, the two supporting rods 3 are both concave, and this arrangement can provide more stable support for the arms and prevent the arms from moving left and right on the supporting rods 3 due to the operation of the nursing staff.

[0026] In the above-mentioned embodiment where both supporting rods 3 are arc-shaped, the two ends of one supporting rod 3 are correspondingly hinged to the upper ends of the two supporting rods 1, and the axis of the hinge is parallel to or coincides with the line between the upper ends of the two supporting rods 1, and the two ends of the other supporting rod 3 are correspondingly hinged to the upper ends of the two supporting rods 2, and the axis of the hinge is parallel to or coincides with the line between the upper ends of the two supporting rods 2, so that the two supporting rods 3 are correspondingly hinged between the upper ends of the two supporting rods 1 and between the upper ends of the two supporting rods 2. In this arrangement, the two supporting rods 3 have a rotation stroke relative to the two supporting rods 1 and the two supporting rods 2, so that the two supporting rods 3 can be kept in a concave shape when the two fork-shaped structures are unfolded to different degrees, so as to ensure the support stability of the arm under different unfolding degrees.

[0027] Preferably, the surfaces of the two supporting rods 3 are both provided with cushions, and the material of the cushions can be cotton cloth, rubber or silicone, which improves the softness of the surfaces of the two supporting rods 3 and improves the comfort when the arms are placed on the two supporting rods 3.

[0028] like Figure 1 As shown, a connecting rod 5 is respectively arranged between the lower ends of the two support rods 1 and between the lower ends of the two support rods 2, that is, there are two connecting rods 5 in total, one of which is arranged between the lower ends of the two support rods 1 for connecting the lower ends of the two support rods 1, and the other connecting rod 5 is arranged between the lower ends of the two support rods 2 for connecting the lower ends of the two support rods 2, thereby improving the structural strength between the two fork-shaped structures and enhancing the stability of the overall structure of the utility model.

[0029] In the present invention, the telescopic mechanism 4 can be arranged between the support rod 1 and the support rod 2 2 of a single fork-shaped structure.

[0030] In a preferred embodiment of the present invention, the telescopic mechanism 4 is arranged between two connecting rods 5. This arrangement has better overall structural symmetry and more stable telescopic adjustment. In this arrangement, the specific connection method can be that the two ends of the telescopic mechanism 4 are fixed to the two connecting rods 5, and the two connecting rods 5 are correspondingly hinged between the lower ends of the two support rods 1 and the lower ends of the two support rods 2, that is, the two ends of one of the connecting rods 5 are correspondingly hinged to the lower ends of the two support rods 1, and the hinge axis coincides with the axis of the connecting rod 5, and the two ends of the other connecting rod 5 are correspondingly hinged to the lower ends of the two support rods 2, and the hinge axis coincides with the axis of the connecting rod 5; or, the two connecting rods 5 are fixed, and the two ends of the telescopic mechanism 4 are correspondingly hinged to the two connecting rods 5 to ensure that the telescopic mechanism 4 can perform its telescopic stroke. When the telescopic mechanism 4 is arranged in this way, its folding direction is the same as Figure 3 on the contrary.

[0031] In another preferred embodiment of the present invention, Figure 1-Figure 3 As shown, the telescopic mechanism 4 is arranged between one of the connecting rods 5 and the supporting rod 3 located above the connecting rod 5. In this arrangement, the telescopic mechanism 4 is arranged vertically on one side, which is more convenient to adjust and easy to adjust during use. In this arrangement, when the supporting rod 3 is hinged, one end of the telescopic mechanism 4 is fixed to the supporting rod 3, and the other end is hinged to the connecting rod 5 or fixed to the connecting rod 5 but the connecting rod 5 is hinged, so as to ensure that the telescopic mechanism 4 can perform its telescopic stroke.

[0032] In the present invention, the telescopic mechanism 4 preferably includes an outer rod 41 and an inner rod 42 inserted in the outer rod 41. A locking bolt 43 for fixing the inner rod 42 is provided on the side of the outer rod 41. Specifically, the locking bolt 43 is inserted in the side of the outer rod 41 and is threadedly connected with the outer rod 41, and the locking end is arranged toward the side of the inner rod 42. By loosening the locking bolt 43, the inner rod 42 can be moved to adjust the degree of expansion of the two fork-shaped structures. After adjusting in place, the locking bolt 43 can be tightened. This setting method has a simple structure and is easy to adjust. The end of the outer rod 41 and the end of the inner rod 42 are the two ends of the telescopic mechanism 4.

[0033] like Figure 1-Figure 3 As shown, the lower ends of the two support rods 1 and the lower ends of the two support rods 2 are both arc-shaped, so that when they are deployed to different degrees, the lower ends of the two support rods 1 and the lower ends of the two support rods 2 can be used to effectively support the whole.

[0034] Preferably, the two support rods 1, the two support rods 2 and the two supporting rods 3 are all made of stainless steel and are hollow structures, such as hollow tube structures, which can meet the structural strength while reducing the overall weight, making it easier to carry, less prone to rust and easier to maintain.
