According to the thickness of the patient's arm, the circle formed by the wristband 12 and the matching plate 14 is first expanded to the maximum, and then the patient's arm is directly passed through the circle. After the arterial blood drawing is completed, the hemostatic frame 1 is moved to the puncture hole, and the wristband 12 is pulled through one end of the matching plate 14 to shrink the circle formed by the wristband 12 and the matching plate 14 until the diameter of the circle corresponds to the diameter of the patient's arm and can be fixed. It is also necessary to ensure that the hemostatic layer 15 is placed at the puncture hole and fits tightly through the pressing component. The hemostatic layer 15 can be composed of medical materials such as medical cotton or dressings, so as to achieve adaptive and stable pressing of the puncture hole for arms or legs of different thicknesses, thereby reducing the situation of prolonged bleeding at the puncture hole.

[0029] like Figures 1 to 3As shown, the outer side of the matching plate 14 is provided with a plug hole 2; the inner wall of the matching plate 14 is plugged with a No. 1 plug rod 21 near the plug hole 2; the plug hole 2 is fixedly connected with a No. 1 elastic member 22, and the No. 1 elastic member 22 is sleeved on the outer side of the No. 1 plug rod 21; the wristband 12 is provided with a plurality of No. 1 round holes 23, and the No. 1 round holes 23 correspond to the diameters of the No. 1 plug rod 21; after drawing blood from the artery, the medical staff first inserts the No. 1 plug rod 21 from the No. 1 plug hole 22 to the No. 1 plug rod 21; The wristband 12 is pulled out from the No. 1 round hole 23, and according to the thickness of the arm of different patients, the wristband 12 is pulled through one end of the matching plate 14, so that the circle formed by the wristband 12 and the matching plate 14 shrinks, and then the No. 1 plug rod 21 is loosened, and the No. 1 plug rod 21 is pulled by the elastic force of the No. 1 elastic member 22. The No. 1 plug rod 21 passes through the plug-in hole 2 and the No. 1 round hole 23 at the same time and is plugged into the inner wall of the matching plate 14, thereby realizing the effect of adaptive contraction and fixation of the arms of different patients.

[0030] like Figure 1 and Figure 5 As shown, the pressing assembly includes a sliding rod 3, a pressing plate 31, a fixed plate 32 and a second elastic member 33; the sliding rod 3 is arranged inside the hemostatic frame 1; the pressing plate 31 is fixedly connected to the bottom end of the sliding rod 3; the fixed plate 32 is threadedly connected to the bottom end of the pressing plate 31, and the hemostatic layer 15 is fixedly connected to the bottom end of the fixed plate 32; the second elastic member 33 is fixedly connected between the inner wall of the hemostatic frame 1 and the pressing plate 31; when pressing the patient's puncture hole, the hemostatic layer 15 is first placed at the puncture hole, and as the circle formed by the wristband 12 and the matching plate 14 shrinks, the arm squeezes the hemostatic layer 15, the second elastic member 33 is squeezed and contracted, and the fixed plate 32 fixed at the bottom of the pressing plate 31 squeezes the sliding rod 3 to slide up, so that the hemostatic layer 15 fits tightly to the puncture hole, achieving the effect of tightly pressing the puncture hole to stop bleeding.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the inner wall of the hemostatic frame 1 is slidably connected with a matching slider 4, and the sliding rod 3 is slidably connected to the inner wall of the matching slider 4; a No. 3 elastic member 41 is fixedly connected between the inner wall of the matching slider 4 and the sliding rod 3; when pressing the puncture hole to stop bleeding, the matching slider 4 is used to slide on the inner wall of the hemostatic frame 1 according to the thickness of the patient's arm, and can be supported on the end of the sliding rod 3 with the No. 3 elastic member 41. When the sliding rod 3 slides up, the position of the hemostatic layer 15 can only be slightly adjusted. If the position of the hemostatic layer 15 needs to be greatly adjusted, it is also necessary to slide the matching slider 4 to greatly adjust the position of the sliding rod 3, thereby improving the close fitting effect of the hemostatic layer 15 on the puncture hole.

[0032] The matching slider 4 is provided with a plurality of No. 2 circular holes 5; the end of the hemostatic frame 1 is fixedly connected to the No. 1 support frame 51 and the No. 2 support frame 52 on both sides close to the matching slider 4, and the No. 1 support frame 51 and the No. 2 support frame 52 are provided with holes corresponding to the No. 2 circular holes 5; the inner wall of the No. 2 support frame 52 is plugged with a No. 2 plug rod 53, and the No. 2 plug rod 53 passes through the No. 2 circular hole 5 and is plugged into the inner wall of the No. 1 support frame 51; the No. 4 elastic member 54 is sleeved on the No. 2 plug rod 53, and the No. 4 elastic member 54 is fixed to the No. 2 support frame When the matching slider 4 is slid according to the different thickness of the patient's arm, the position of the matching slider 4 is adjusted, and the No. 2 plug rod 53 is pulled out first, and the No. 4 elastic member 54 is pulled and stretched. At this time, the position of the sliding matching slider 4 is adjusted. After the sliding is completed, the No. 2 plug rod 53 is released, and the No. 4 elastic member 54 is used to pull the No. 2 plug rod 53 with its elastic force, so that the No. 2 plug rod 53 passes through the corresponding holes of the No. 2 support frame 52, the No. 2 round hole 5 and the No. 1 support frame 51, thereby achieving the effect of fixing the position of the matching slider 4.

[0033] A pressure sensor 6 is installed inside the matching slider 4; a fixed tube 61 is fixedly connected to the end of the sliding rod 3; a spring 62 is fixedly connected to the inner wall of the fixed tube 61; a squeezing rod 63 is slidably connected to the inner wall of the fixed tube 61, and the end of the squeezing rod 63 fits the bottom end of the pressure sensor 6, and the squeezing rod 63 is located on the spring 62; when the hemostatic layer 15 fits the patient's puncture hole, the patient's arm is used to squeeze the sliding rod 3 and drive the fixed tube 61 to slide up. During the sliding of the fixed tube 61, the squeezing spring 62 contracts, and the squeezing rod 63 is squeezed and slides up by the elastic force of the spring 62. The end of the squeezing rod 63 away from the spring 62 squeezes the pressure sensor 6. After the pressure sensor 6 is squeezed, it sends a signal to the controller, and the controller starts timing. When the time set by the medical staff is reached, the controller sends a signal to remind the person wearing the medical hemostatic device to remove the device, which serves as a warning and reminder of the length of time the medical hemostatic device is worn.

[0034] like Figure 1 and Figure 4As shown, the outer wall of the hemostatic frame 1 is fixedly connected with an ice box 7, and the material of the ice box 7 is metal; a cover 71 is clamped on the ice box 7; an overflow hole is opened on one side of the ice box 7; the inner wall of the overflow hole is threadedly connected with a threaded plug 72; after blood is drawn from the artery, in order to accelerate the hemostasis of the puncture hole, local cold compress can be applied, moderate pressure can be applied, and blood vessel contraction can be promoted, thereby reducing bleeding. Before blood drawing, the cover 71 is removed first, and ice cubes are placed inside the ice box 7 for temporary storage, and then the cover 71 is stuffed back into the ice box 7 to seal it. When the hemostatic layer 15 presses the puncture hole, the ice cubes transfer the low temperature to the metal ice box 7, and the ice box 7 fits one side of the puncture hole. The ice box 7 can apply cold compress to the side of the puncture hole, thereby promoting blood vessel contraction. After the medical hemostatic device is used, the threaded plug 72 is opened to discharge the ice water.

[0035] like Figures 1 to 3 As shown, the outer wall of the wristband 12 is fixedly connected to a No. 1 sponge pad 8; the outer wall of the matching plate 14 is fixedly connected to a No. 2 sponge pad 81; when the wristband 12 and the matching plate 14 form a loop around the patient's arm, the No. 1 sponge pad 8 is matched with the No. 2 sponge pad 81 to be fixed to the outer walls of the wristband 12 and the matching plate 14 respectively, and the flexibility of the No. 1 sponge pad 8 and the No. 2 sponge pad 81 is utilized to improve the comfort of the arm being tightly restrained, thereby reducing the sense of oppression caused by wearing the medical hemostatic device for a long time.

[0036] like Figure 1 and Figure 3 As shown, a guide groove 9 is provided at the bottom end of the matching plate 14; the cross-sectional shape of the guide groove 9 is trapezoidal; when the wristband 12 falls off from the inner wall of the matching plate 14 and is reinserted, the guide groove 9 provided at the bottom end of the matching plate 14 is used for guidance, and the end of the wristband 12 away from the No. 1 rotating rod 11 is close to the guide groove 9 and then directly inserted into the matching plate 14. The inclined surface of the trapezoidal guide groove 9 guides the wristband 12 to slide into the inner wall of the matching plate 14, thereby facilitating the insertion of the wristband 12 into the matching plate 14.

[0037] like Figures 1 to 3 As shown, the length of the No. 1 sponge pad 8 starts from one end of the wristband 12 and ends at the No. 1 circular hole 23 on the wristband 12; a plurality of anti-skid protrusions are fixedly connected to the No. 1 sponge pad 8 and the No. 2 sponge pad 81; when the patient wears the medical hemostatic device, the medical hemostatic device may slip off because some patients' skin may be lubricated or smooth. By providing a plurality of anti-skid protrusions on the No. 1 sponge pad 8 and the No. 2 sponge pad 81, the wearing stability of the medical hemostatic device can be improved.

[0038] Working process: When drawing blood from an artery for patients with limited limb mobility or critical illness, some patients have difficulty in adapting to the pressure on the puncture site due to the different thickness of their arms or legs. The hemostatic frame 1 is used as the core support structure of the pressing component. The wristband 12 is connected to one side of the hemostatic frame 1 by rotating with the No. 1 rotating rod 11. The wristband 12 passes through the inside of the matching plate 14 connected to the No. 2 rotating rod 13. According to the thickness of the patient's arm, the circle formed by the wristband 12 and the matching plate 14 is first expanded to the maximum, and then the patient's arm is directly passed through the circle. After the arterial blood drawing is completed, the hemostatic frame 1 is moved to the puncture site, and the wristband 12 is pulled through one end of the matching plate 14, so that the circle formed by the wristband 12 and the matching plate 14 shrinks until the diameter of the circle corresponds to the diameter of the patient's arm. It can be fixed, and it is necessary to ensure that the hemostatic layer 15 is placed at the puncture hole and fits tightly through the pressing component, so as to realize adaptive pressing of the puncture hole for arms or legs of different thicknesses, and reduce the situation of prolonged bleeding at the puncture hole; after drawing blood from the artery, the medical staff first pulls the No. 1 insertion rod 21 out of a No. 1 circular hole 23, and according to the thickness of the arm of different patients, pulls the wristband 12 through one end of the matching plate 14, so that the circle formed by the wristband 12 and the matching plate 14 shrinks, and then releases the No. 1 insertion rod 21, and relies on the elastic force of the No. 1 elastic member 22 to pull the No. 1 insertion rod 21, and the No. 1 insertion rod 21 simultaneously passes through the plug hole 2 and the No. 1 circular hole 23 and is plugged into the inner wall of the matching plate 14, so as to realize the effect of adaptive contraction and fixation of the arms of different patients;

[0039] When pressing the puncture hole of the patient, the hemostatic layer 15 is first placed at the puncture hole. As the circle formed by the wristband 12 and the matching plate 14 shrinks, the arm squeezes the hemostatic layer 15, and the No. 2 elastic member 33 is squeezed and contracted. The fixed plate 32 fixed at the bottom of the pressing plate 31 squeezes the sliding rod 3 to slide up, so that the hemostatic layer 15 fits tightly to the puncture hole, and the puncture hole is pressed tightly to stop bleeding. When pressing the puncture hole to stop bleeding, the matching slider 4 is used to slide on the inner wall of the hemostatic frame 1 according to the thickness of the patient's arm, and can cooperate with the No. 3 elastic member 41 to support the end of the sliding rod 3. When the sliding rod 3 slides up, the position of the hemostatic layer 15 can only be slightly adjusted. If the position of the hemostatic layer 15 needs to be adjusted significantly, the sliding matching slider 4 needs to be slid to adjust the position of the sliding rod 3 significantly, thereby improving the close fitting effect of the hemostatic layer 15 on the puncture hole; when the sliding matching slider 4 is slid according to the different thickness of the patient's arm, the position of the matching slider 4 is adjusted, and the No. 2 plug rod 53 is pulled out first, and the No. 4 elastic member 54 is pulled and stretched. At this time, the position of the sliding matching slider 4 is slid. After the sliding is completed, the No. 2 plug rod 53 is released, and the No. 4 elastic member 54 is used to pull the No. 2 plug rod 53 with its elastic force, so that the No. 2 plug rod 53 passes through the corresponding holes of the No. 2 support frame 52, the No. 2 round hole 5 and the No. 1 support frame 51 and is fixed, thereby achieving the effect of fixing the position of the matching slider 4;

[0040] When the hemostatic layer 15 is attached to the puncture hole of the patient, the patient's arm is used to squeeze the sliding rod 3 and drive the fixed tube 61 to slide up. During the sliding of the fixed tube 61, the squeezing spring 62 contracts, and the squeezing rod 63 is squeezed and slid up by the elastic force of the spring 62. The end of the squeezing rod 63 away from the spring 62 squeezes the pressure sensor 6. After being squeezed, the pressure sensor 6 sends a signal to the controller, and the controller starts timing. When the time set by the medical staff is reached, the controller sends a signal to remind the person wearing the medical hemostatic device to remove the device, which serves as a warning to remind the person to wear the medical hemostatic device for a long time.

[0041] After drawing blood from the artery, in order to accelerate the hemostasis of the puncture hole, local cold compress can be applied and moderate pressure can be applied to promote blood vessel contraction, thereby reducing bleeding. Before drawing blood, the cover 71 is removed first, and ice cubes are placed inside the ice box 7 for temporary storage, and then the cover 71 is plugged back into the ice box 7 to seal it. When the hemostatic layer 15 presses the puncture hole, the ice cubes transfer the low temperature to the metal ice box 7, and the ice box 7 fits one side of the puncture hole. The ice box 7 can apply cold compress to the side of the puncture hole, thereby promoting blood vessel contraction. After the medical hemostatic device is used, the threaded plug 72 is opened to discharge the ice water.

[0042] When the wristband 12 and the matching plate 14 form a loop around the patient's arm, the No. 1 sponge pad 8 is used to match the No. 2 sponge pad 81 to be fixed to the outer wall of the wristband 12 and the matching plate 14 respectively, and the flexibility of the No. 1 sponge pad 8 and the No. 2 sponge pad 81 is used to improve the comfort of tightly constricting the arm, thereby reducing the pressure caused by wearing the medical hemostatic device for a long time; when the patient wears the medical hemostatic device, because some patients' skin will be smeared with lubricants or is relatively smooth, which may cause the medical hemostatic device to slip off when worn, and multiple anti-slip bumps are provided on the No. 1 sponge pad 8 and the No. 2 sponge pad 81, which can improve the stability of wearing the medical hemostatic device;

[0043] When the wristband 12 falls off from the inner wall of the matching plate 14 and is reinserted, the guide groove 9 provided at the bottom end of the matching plate 14 is used for guidance. The end of the wristband 12 away from the No. 1 rotating rod 11 is close to the guide groove 9 and then directly inserted into the matching plate 14. The inclined surface of the trapezoidal guide groove 9 guides the wristband 12 to slide into the inner wall of the matching plate 14, thereby facilitating the insertion of the wristband 12 into the matching plate 14.
