The front and rear sides of the top of the bottom pressure head 36 are respectively fixedly connected with the bottom pressure head slide rod 35. The outer walls of the two bottom pressure head slide rods 35 are respectively slidably connected to the inner walls of the two pressing tube bottom slide grooves 32. The pressing tube shell 31, the internal pressure tube 37 and the middle part of the inner wall of the bottom pressure head 36 are rotatably connected with a screw rod 39. The top of the screw rod 39 extends to the top of the inner wall of the pressing tube shell 31 and is fixedly connected with a screw shaft 310. A pentagonal joint 311 is provided on the top of the screw shaft 310. The left and right sides of the inner wall of the sliding shaft 44 are respectively fixedly connected with Sliding shaft connecting rod 45, the inner sides of the two sliding shaft connecting rods 45 extend to the inner wall of the pressing tube housing 31 through the two pressing tube top slide grooves 312 and are fixedly connected with a sleeve 46, the left and right sides of the inner wall of the sleeve 46 are respectively provided with sleeve slide grooves 47, the inner walls of the two sleeve slide grooves 47 are both slidably connected with a transmission tube 48, the inner sides of the two transmission tubes 48 are fixedly connected with a transmission tube slide rod 49, the inner wall of the transmission tube slide rod 49 is threadedly connected to the outer wall of the screw rod 39, the left and right sides of the inner wall of the pressurizing tube housing 41 are respectively fixedly connected with an inner rack rod 43, and the inner sides of the two inner rack rods 43 are respectively meshed with the outer sides of the two gears 34;

[0036] When hemostasis is required, first hold the pressing handle 1 tightly. At this time, the pressing handle 1 pushes the pressing outer tube 2 to move forward, and the pressing outer tube 2 drives the pressing tube 3 and all the structures inside the pressing tube 3 to move forward together until the bottom pressure head 36 contacts the wound, and then the bandage is put on the outer wall of the pressing handle 1 and fixed to the skin around the patient's wound. When the bottom pressure head 36 is pressed under force, the bottom pressure head 36 and the internal pressure tube 37 and rack rod 38 on its top slide upward at the bottom of the inner wall of the pressing tube shell 31. In the process of the internal pressure tube 37 and the rack rod 38 sliding upward, the rack rod 38 engages with the gear 34 to stop the bleeding. The two gears 34 rotate, and the two gears 34 rotate and then mesh with the two inner rack rods 43 on the outside to drive the pressurized tube shell 41 to move downward. When the pressurized tube shell 41 moves downward, the sleeve 46 on the inner wall thereof slides on the outer wall of the transmission tube slide rod 49 until the pressurized tube shell 41 fits with the top of the bottom pressure head 36. At this time, the pressurized tube shell 41 pressurizes the bottom pressure head 36, so that the bottom pressure head 36 applies greater pressure to the wound to achieve a better hemostasis effect. At the same time, due to the pressurization effect of the pressurized tube 4, the air in the pressing tube 3 is squeezed, further enhancing the pressure of the bottom pressure head 36 on the wound.

[0037] When it is necessary to adjust the pressure of the bottom pressure head 36, a rotating rod with the same shape as the pentagonal joint 311 opened at the top of the screw shaft 310 is connected to the pentagonal joint 311, and the screw shaft 310 is driven to rotate by rotating the rotating rod. The rotation of the screw shaft 310 drives the screw 39 to rotate in the middle of the inner wall of the pressing tube housing 31, the internal pressure tube 37 and the bottom pressure head 36. Since the inner wall of the transmission tube slide rod 49 is threadedly connected to the outer wall of the screw rod 39, when the screw rod 39 rotates, the transmission tube slide rod 49 and the transmission tube 48 inside the transmission tube slide rod 49 are driven by the action of the thread to slide in the sleeve groove on the inner wall of the sleeve 46 47 moves upward or downward, and the transmission tube 48 moves to drive the pressurized tube shell 41 and all the structures inside the pressurized tube shell 41 to move upward or downward together, thereby adjusting the distance between the pressurized tube shell 41 and the bottom pressure head 36. When the distance between the pressurized tube shell 41 and the bottom pressure head 36 decreases, the pressure force of the bottom pressure head 36 on the wound increases. When the distance between the pressurized tube shell 41 and the bottom pressure head 36 increases, the pressure force of the bottom pressure head 36 on the wound decreases. By adjusting the pressure force of the bottom pressure head 36 on the wound, the hemostatic device can adapt to the hemostatic needs of different wounds, thereby improving the practicality and applicability of the hemostatic device.

[0038] like Figure 8-10As shown, the cotton pad positioning mechanism 5 includes a cross slide plate 51, the top of the cross slide plate 51 is fixedly connected to the top of the inner wall of the bottom pressure head, the top of the cross slide plate 51 is fixedly connected to a connecting tube 53, the top of the connecting tube 53 is fitted with the bottom of the internal pressure tube 37, the middle part of the cross slide plate 51 is a hollow design, the left and right sides of the rear side of the cross slide plate 51 are respectively fixedly connected with cross slide plate connecting rods 52, the bottoms of the two cross slide plate connecting rods 52 are fixedly connected with slide plates 54, the top annular array of the slide plates 54 is provided with slide grooves 55, the slide plate 54 and the inner side of the cross slide plate 51 are movably connected with a positioning assembly 56, and the positioning assembly 56 includes a transmission shaft 561, the inner wall of the transmission shaft 561 is threadedly connected to the bottom of the outer wall of the screw rod 39, the outer wall of the transmission shaft 561 is fixedly connected to the rotating rod connecting rod 562 in an annular array, the top and bottom of the outer walls of the multiple rotating rod connecting rods 562 are rotatably connected to the rotating rod 563, the multiple groups of rotating rods 563 are rotatably connected to the side away from the rotating rod connecting rod 562, the inner tops of the multiple receiving and expanding plates 564 are fixedly connected to the receiving and expanding plate sliders 565, the outer walls of the multiple receiving and expanding plate sliders 565 are slidably connected to the inner wall of the cross slide plate 51, and the outer wall bottoms of the multiple receiving and expanding plates 564 are respectively slidably connected to the inner walls of the multiple slide grooves 55 opened by the slide groove plate 54;

[0039] When the screw rod 39 rotates, the transmission shaft 561 will perform a threaded lifting motion along the outer wall of the screw rod 39, thereby driving the rotating rod connecting rod 562 and the rotating rod 563 to lift together. As the transmission shaft 561 rises and falls, the rotating rod 563 will rotate around the axis of the rotating rod connecting rod 562, and this rotation will be converted into an expansion or contraction action of the expansion plate 564. Specifically, when the transmission shaft 561 rises, the rotating rod 563 will push the expansion plate 564 to slide outward along the slide groove 55, so that the angle between the expansion plate 564 increases, thereby achieving an expansion effect. Conversely, when the transmission shaft 561 descends, the rotating rod 563 will pull the expansion plate 564 to slide inward along the slide groove 55, so that the angle between the expansion plate 564 decreases, thereby achieving a contraction effect. Through this design, the cotton pad is accurately positioned at the patient's wound site, improving the hemostatic effect, avoiding misalignment or displacement of the alcohol cotton pad, and further ensuring the stability and reliability of hemostasis. At the same time, the expansion or contraction action of the expansion plate 564 can be controlled by adjusting the rotation direction and speed of the screw rod 39, thereby achieving precise adjustment of the pressure force of the cotton pad.

[0040] Working principle of the present invention: when it is necessary to stop bleeding, first hold the pressing handle 1 tightly, at this time the pressing handle 1 pushes the pressing outer tube 2 to move forward, the pressing outer tube 2 drives the pressing tube 3 and all the structures inside the pressing tube 3 to move forward together, until the bottom pressure head 36 contacts the wound, and then the bandage is put on the outer wall of the pressing handle 1 and fixed to the skin around the patient's wound. When the bottom pressure head 36 is pressed under force, the bottom pressure head 36 and the internal pressure tube 37 and the rack rod 38 at its top slide upward at the bottom of the inner wall of the pressing tube shell 31. In the process of the internal pressure tube 37 and the rack rod 38 sliding upward In the embodiment, the rack rod 38 is meshed with the gear 34, so that the two gears 34 rotate, and the two gears 34 rotate and mesh with the two inner rack rods 43 on the outside to drive the pressurized tube housing 41 to move downward. When the pressurized tube housing 41 moves downward, the sleeve 46 on the inner wall thereof slides on the outer wall of the transmission tube slide rod 49 until the pressurized tube housing 41 fits with the top of the bottom pressure head 36. At this time, the pressurized tube housing 41 pressurizes the bottom pressure head 36, so that the bottom pressure head 36 applies greater pressure to the wound, thereby achieving a better hemostasis effect. At the same time, due to the pressurization of the pressurized tube 4, the pressing The air in the tube 3 is squeezed, further enhancing the pressure of the bottom pressure head 36 on the wound. When the pressure of the bottom pressure head 36 needs to be adjusted, a rotating rod with the same shape as the pentagonal joint 311 opened at the top of the screw shaft 310 is connected to the pentagonal joint 311, and the screw shaft 310 is driven to rotate by rotating the rotating rod. The rotation of the screw shaft 310 drives the screw 39 to rotate in the middle of the inner wall of the pressing tube housing 31, the internal pressure tube 37 and the bottom pressure head 36. Since the inner wall of the transmission tube slide rod 49 is threadedly connected to the outer wall of the screw rod 39, when the screw rod 39 rotates, the thread The transmission tube slide bar 49 and the transmission tube 48 inside the transmission tube slide bar 49 move upward or downward in the sleeve slide groove 47 on the inner wall of the sleeve 46. The movement of the transmission tube 48 drives the pressurized tube shell 41 and all the structures inside the pressurized tube shell 41 to move upward or downward together, thereby adjusting the distance between the pressurized tube shell 41 and the bottom pressure head 36. When the distance between the pressurized tube shell 41 and the bottom pressure head 36 decreases, the pressure force of the bottom pressure head 36 on the wound increases. When the distance between the pressurized tube shell 41 and the bottom pressure head 36 increases, the pressure force of the bottom pressure head 36 on the wound decreases.

[0041] When the screw rod 39 rotates, the transmission shaft 561 will perform a threaded lifting motion along the outer wall of the screw rod 39, thereby driving the rotating rod connecting rod 562 and the rotating rod 563 to lift and lower together. As the transmission shaft 561 rises and falls, the rotating rod 563 will rotate around the axis of the rotating rod connecting rod 562, and this rotation will be converted into an expansion or contraction action of the expansion plate 564. Specifically, when the transmission shaft 561 rises, the rotating rod 563 will push the expansion plate 564 to slide outward along the slide groove 55, so that the angle between the expansion plates 564 increases, thereby achieving an expansion effect. Conversely, when the transmission shaft 561 descends, the rotating rod 563 will pull the expansion plate 564 to slide inward along the slide groove 55, so that the angle between the expansion plates 564 decreases, thereby achieving a contraction effect.
