Figure 4 As shown, a positioning frame 5 is fixed on one side of the fixing plate 4, and a pressing plate 6 is arranged inside the positioning frame 5. One side of the pressing plate 6 is connected to the fixing plate 4 or the positioning frame 5, and the other side of the pressing plate 6 (the side opposite to the fixing plate 4 or the positioning frame 5) is detachably connected to the fixing plate 4, as shown in FIG. Figure 5 As shown, a pressure bag 18 is fixedly installed at the bottom of the pressing plate 6, and the pressure bag 18 is arranged in the positioning frame 5 and between the bottom of the pressing plate 6 and the fixed plate 4. A hemostatic cotton 21 is arranged on the side of the pressure bag 18 away from the pressing plate 6. The area of the hemostatic cotton 21 is set to be smaller than the area of the pressing plate 6, which can facilitate the replacement of the hemostatic cotton 21.
[0036] In this embodiment, the hemostatic cotton 21 is arranged in the positioning frame 5 and between the pressure bag 18 and the fixing plate 4. A through hole is provided on the fixing plate 4 at the middle position of the area surrounded by the positioning frame 5, and the through hole is smaller than the size of the positioning frame 5. After the pressure bag 18 is inflated, the part of the pressure bag 18 away from the side of the pressure plate 6 and located at the position of the through hole passes through the through hole, thereby pushing the part of the hemostatic cotton 21 also located at the position of the through hole out of the through hole.
[0037] like Figure 5 As shown, the pressure bag 18 is fixedly mounted with an inlet and outlet valve 13 and a pressure sensor 12, and the pressure sensor 12 and the inlet and outlet valve 13 are both fixedly mounted on the pressure plate 6. Among them, the pressure sensor 12 itself has a display screen that can display the value of the currently measured pressure.
[0038] like Figure 4 As shown, a first connecting strip 7 is fixedly mounted on the top of the fixing plate 4, a first connecting belt 8 is fixedly mounted on the first connecting strip 7, a second connecting strip 9 is fixedly mounted on the side of the first connecting belt 8 away from the first connecting strip 7, and the second connecting strip 9 is fixedly mounted on the pressing plate 6. The height of the first connecting strip 7 matches the height of the positioning frame 5.
[0039] like Figure 4 As shown, the pressure plate 6 is symmetrically fixedly installed with two third connecting strips 14, the third connecting strips 14 are fixedly installed with second connecting belts 15, and the second connecting belts 15 are rotatably installed with connecting bolts 16, and the fixing plate 4 is symmetrically fixedly installed with two connecting blocks 17, one side of the connecting bolts 16 extends into the connecting block 17 and is threadedly connected with the connecting block 17. (Wherein, the number of the third connecting strips 14, the second connecting belts 15, the connecting bolts 16, and the connecting blocks 17 is the same, and there is at least one of each)
[0040] like Figure 3 As shown, a mounting hole is provided on the top of the plastic plate 1 , an annular groove 3 is provided on the inner wall of the mounting hole, and the sides of the fixing plate 4 are fixedly installed in the annular groove 3 .
[0041] like Figure 6 As shown, a fixing hole 20 is opened on one side of the pressure bag 18 close to the pressure plate 6 , and the pressure sensor 12 is fixedly installed in the fixing hole 20 .
[0042] The pressure bag 18 is provided with a plurality of observation holes 19 distributed in an annular shape, and the observation holes 19 penetrate the upper and lower ends of the pressure bag 18, but the observation holes 19 are separated from the inside of the pressure bag 18 and are not connected. The fixed plate 4 is provided with a plurality of mounting holes 10 in an annular shape, and a transparent plate 11 is fixedly mounted in the mounting holes 10, and the position and size of the transparent plate 11 and the observation holes 19 are adapted. The transparent plate 11 and the observation holes 19 are both located in the through hole area of the fixed plate 4.
[0043] The working principle of the hemodialysis room care hemostasis device provided by the present invention is as follows:
[0044] When in use, after the patient has finished dialysis, the hemostatic cotton 21 of the device of the present invention is first spread on the patient's wound, and then the Velcro on the two straps 2 on both sides of the plastic plate 1 is used to fix the entire device of the present invention to the patient's wound (i.e., on the wrist), and then the air inlet and outlet valve 13 is connected to the inflation device (for example, an inflation pump) through a pipeline, and can also be connected to the hospital's oxygen supply pipeline to inflate the pressure bag 18. During the inflation process, the pressure in the pressure bag 18 is directly displayed by the pressure sensor 12, so that the pressure on the patient's wound can be judged. The inflated pressure bag 18 squeezes the patient's wound through the hemostatic cotton 21, so as to ensure the normal healing of the patient's wound;
[0045] During the wound healing process, the transparent plate 11 and the observation hole 19 can timely detect whether there is bleeding in the wound of the patient, and the pressure value of the wound of the patient can be adjusted according to the amount of bleeding in the wound of the patient; thus, the pressure bag 18 can be exhausted or inflated, so that the appropriate pressure intensity can be set according to the individual differences of different patients to stop bleeding;
[0046] When the hemostatic cotton 21 needs to be replaced during the healing process of the patient's wound to ensure the cleanliness of the patient's wound and avoid infection of the patient's wound, first, the pressure bag 18 is deflated through the air inlet and outlet valves 13, and then the connecting bolt 16 is rotated until the connecting bolt 16 is removed from the connecting block 17. At this time, the two second connecting belts 15 are pulled to move, and the second connecting belts 15 drive the pressure plate 6 and the pressure bag 18 to move out of the positioning frame 5. At this time, the old hemostatic cotton 21 can be removed, and then replaced with a new hemostatic cotton 21, and then the above steps are reversed to complete the replacement of the hemostatic cotton 21.
[0047] In another embodiment, the hemostatic cotton 21 in the device of the present invention is eliminated, and after the hemostatic cotton 21 is spread on the patient's wound, the device of the present invention is used to press the hemostatic cotton 21 on the patient's wound through the pressure bag 18 protruding from the through hole.
[0048] Example 2
[0049] In this embodiment, the present invention provides a hemodialysis room care hemostasis device, such as Figure 9-13As shown, it also includes a support bar 22 fixedly installed at one end of one of the straps 2, one end of two connecting ropes 23 are symmetrically fixedly installed on one side of the support bar 22, a limiting column 26, a protective cover 25 sleeved on the outside of the limiting column 26 and one end of a spring 30 are fixedly installed on the other strap 2, a brake block 27 is provided on the outer sliding sleeve of the limiting column 26, a take-up roller 28 is provided on the top of the brake block 27, the take-up roller 28 is rotatably installed in the protective cover 25, and a limiting groove matching the take-up roller 28 is provided in the protective cover 25, so that the take-up roller 28 can only rotate in the protective cover 25 and cannot slide up and down. The brake block 27 is meshed with the take-up roller 28, and a rotating column 29 is slidably installed in the take-up roller 28. The bottom end of the rotating column 29 contacts the brake block 27, and the top of the rotating column 29 extends to the protective cover 25 and is fixedly installed with a rotating knob. The spring 30 is sleeved on the outside of the limit column 26, and the other end of the spring 30 is fixedly installed on the bottom of the brake block 27. The top of the brake block 27 and the bottom of the take-up roller 28 are both fixedly installed with ring-shaped wedge-shaped teeth. The brake block 27 and the take-up roller 28 are connected by a plurality of wedge-shaped teeth, and the other end of the connecting rope 23 is fixedly wound around the outside of the take-up roller 28.
[0050] Two guide rollers 24 are symmetrically fixedly mounted on the other binding belt 2 , and the connecting rope 23 is connected to the guide rollers 24 .
[0051] like Fig.13 As shown, a cylindrical cavity 32 with a non-circular cross section is provided in the brake block 27, and a cylindrical block 31 with a cross section matching the cylindrical cavity 32 in the brake block 27 is provided at the other end of the limiting column 26. The cylindrical block 31 is arranged in the cylindrical cavity 32, and the height of the cylindrical block 31 is less than the height of the cylindrical cavity 32, so that there is a sliding space for the cylindrical block 31 in the cylindrical cavity 32. In this embodiment, the non-circular cylindrical cavity 32 in the brake block 27 is a square cavity, and the cylindrical block 31 at the other end of the limiting column 26 is a square block.
[0052] The take-up roller 28 is provided with a sliding hole, the rotating column 29 passes through the sliding hole, the inner wall of the sliding hole is provided with a sliding groove 34 , the outer side of the rotating column 29 is fixedly installed with a sliding block 33 , and the slider 33 is slidably installed in the sliding groove 34 .
[0053] In this embodiment, the bandage 2 is made of plastic material. When the entire hemostatic device needs to be installed, the entire device is firstly put on the patient, and then the hemostatic cotton 21 is spread on the patient's wound. Then the hemostatic device of the present invention is moved to make the pressure bag 18 face the hemostatic cotton 21, and then the rotating column 29 is rotated. The rotating column 29 drives the take-up roller 28 to rotate, so that the take-up roller 28 takes up the connecting rope 23. In the above process, since the wedge-shaped teeth are arranged between the brake block 27 and the take-up roller 28, when the take-up roller 28 rotates, the rotation of the take-up roller 28 causes the brake block 2 7 is continuously moved downward to engage, thereby ensuring the normal winding of the wire-receiving roller 28, until the bandage 2 and the plastic plate 1 are in contact with the patient's skin, at which time the fixing work of the entire hemostatic device is completed; when the entire device needs to be removed from the patient, it is only necessary to push down the rotating column 29, and the rotating column 29 pushes the brake block 27 to move downward on the outside of the limiting column 26 until the wedge-shaped teeth on the brake block 27 are out of contact with the wedge-shaped teeth on the wire-receiving roller 28, at which time the rotating column 29 can be rotated in the opposite direction, so that the connecting rope 23 can be loosened, until the entire device can be removed from the patient.
[0054] The above structure in this embodiment can replace the fastening method of Example 1 in which the two straps 2 are detachably connected by Velcro.
