Detailed implementation manners
[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0026] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.
[0027] Please refer to Figures 1 to 4 , a femoral artery injection catheter postoperative body position fixator provided by an embodiment of the present utility model, the femoral artery injection catheter postoperative body position fixator includes: a fixing device 1, the fixing device 1 includes a waist wearer 11 and a leg wearer 12, and a limiting component 4 for connection is provided between the waist wearer 11 and the leg wearer 12.
[0028] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , the limiting component 4 includes a support plate 41, the upper side of the outer wall of the support plate 41 is connected to the waist wearer 11, a rotatably connected connecting rod 42 is inserted in the lower part of the support plate 41, and the end of the connecting rod 42 is connected to the leg wearer 12; a sleeve 421 is provided on the outer wall of the connecting rod 42 away from the leg wearer 12, a rib 422 is provided on the outside of the sleeve 421, and a limiting insertion rod 44 is inserted at a position of the support side wall opposite to the rib 422, a plurality of annularly distributed connection holes 411 are provided on one side of the support plate 41 away from the leg wearer 12, the connection holes 411 are located outside the connecting rod 42, and the inner wall of the connection hole 411 is threadedly connected to the end of the limiting insertion rod 44, and an annular scale 43 is provided outside a plurality of connection holes 411 on the outer part of the support plate 41.
[0029] It should be noted that: After wearing the waist fixator and the leg fixator in the later stage, medical staff can remove the limit insertion rod 44 as needed, and insert the limit insertion rod 44 into the corresponding connection hole 411 by comparing it with the annular scale 43. Then, when the patient moves the leg in the later stage and drives the leg wearing device 12 to rotate, the convex strip 422 can be driven to rotate synchronously through the connecting rod 42. At this time, the limit insertion rod 44 on the support plate 41 can limit the rotation angle of the convex strip 422 by abutting against the convex strip 422. Thus, it can be avoided that when the patient moves the leg in the later stage, the catheter is displaced, twisted or broken due to excessive angle, and the use effect of the device in the later stage can be improved.
[0030] In an embodiment of the present invention, please refer to Figure 1 and Figure 4 , a viewing window 121 is opened inside the leg wearing device 12. A fixing frame 3 is adhered to the viewing window 121 through a magic tape, and a transparent sheet 31 is arranged inside the fixing frame 3.
[0031] It should be noted that: By opening a through window on the leg wearing device 12, it is convenient for medical staff or patients to observe the wound state in time during the wearing and use of the device in the later stage, thereby reducing the hidden danger brought by wound oozing blood and untimely treatment. Since the fixing frame 3 is connected by a magic tape, when in use, the staff can tear open one side of the fixing frame 3, which is convenient for the staff to connect the external medicine injection tube to the medicine injection catheter for medicine injection.
[0032] In an embodiment of the present invention, please refer to Figure 1 and Figure 4 , bandages 2 are arranged on the side walls of the waist wearing device 11 and the leg wearing device 12. The end of the bandage 2 is adhesively connected to the waist wearing device 11 and the leg wearing device 12 through a magic tape, and a scale bar is arranged on the outer wall of the leg bandage.
[0033] It should be noted that: By arranging a scale bar on the bandage 2, medical staff can control the wearing accuracy for the patient through the scale bar on the bandage 2 when helping the patient wear the device in the later stage, thereby improving the wearing comfort of the device in the later stage. And in the later stage, the change of the leg circumference can be known by observing the tightness of the bandage 2, so as to timely detect the formation or detachment of deep vein thrombosis of the lower extremities.
[0034] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , metal support bars are inlaid inside both the waist wearing device 11 and the leg wearing device 12. The metal support bar in the waist wearing device 11 is connected to the support plate 41, and the metal support bar in the leg wearing device 12 is connected to the connecting rod 42.
[0035] It should be noted that by setting the metal support bars (not shown in the figure), the support strength inside the waist wearer 11 and the leg wearer 12 can be increased, preventing the leg wearer 12 from rotating during later use, and thus improving the restriction on the range of movement of the patient's legs.
[0036] The working principle of the femoral artery injection catheter postoperative body position fixator provided by the present utility model is as follows;
[0037] In the later stage, when medical staff complete the operation and need to fix the pre-embedded catheter, the medical staff can first tie the waist wearer 11 and the leg wearer 12 around the patient's waist and leg respectively, and then tie and wear the waist wearer 11 and the leg wearer 12 respectively through the bandage 2. During this wearing process, the accuracy of the tying can also be controlled through the scale bar on the outer wall of the bandage 2;
[0038] After completing the wearing of the device, the pre-embedded pipeline can be adhesively fixed to the leg wearer 12 through the adhesive strip. Then, the fixing frame 3 can be adhesively fixed outside the viewing window 121 through the magic tape, which can not only seal the viewing window 121, but also enable medical staff or patients to timely observe the state of the injection catheter wound site through the transparent sheet 31 in the fixing frame 3;
[0039] Since the fixing frame 3 is adhesively fixed through the magic tape, it is also convenient for the staff to connect the external injection tube to the injection catheter for injection during use;
[0040] After completing the wearing of this device, the medical staff can also take out the limit insertion rod 44 as needed and insert the limit insertion rod 44 into the corresponding connection hole 411 through comparison with the circular scale 43. Subsequently, when the patient needs to move the leg, the leg wearer 12 can be driven to rotate. At this time, the leg wearer 12 can drive the convex strip 422 on the outer wall to rotate through the connecting rod 42. At this time, the limit insertion rod 44 outside the convex strip 422 can limit the rotation angle of the convex strip 422 by abutting against the convex strip 422, thereby preventing the catheter from being displaced, distorted or broken due to excessive angle during the patient's later leg movement, and thus improving the later use effect of this device;
[0041] In the later stage, after the medical staff removes the reserved pipeline, a pressure-fixing adhesive strip can also be pasted between the observation window and the wound site to reduce the phenomenon of bleeding and hematoma at the wound site due to movement, and thus the use of this device can be completed.
[0042] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
