[0026] In this embodiment, one side of the bottom of the pressing block 5 engages with the middle of the knob 7, one end of the knob 7 is rotated to connect to one side of the latch 16, the outer side of the latch 16 is slidably connected to the inner wall of the pressing block 5, the inner side of the bottom of the pressing block 5 is slidably connected to the lifting block 14, the top of the lifting block 14 is fixedly connected to the top of the small spring 15, and the bottom of the small spring 15 is fixedly connected to the pressing block 5.

[0027] By turning the knob 7 , the latch 16 can be controlled to press the lifting block 14 , so that the lifting block 14 extends out from the bottom of the pressing block 5 .

[0028] In this embodiment, a slide groove is formed on the top of the lifting block 14, the other side of the latch 16 is an inclined surface, a T hole is formed in the center of the bottom of the pressing block 5, and a screw hole is formed on one side of the bottom of the pressing block 5.

[0029] The latch 16 can be used to control the lifting block 14 to maintain or release the extended state, thereby adjusting the pressure of the central part of the coverage area of ​​the pressing block 5.

[0030] In this embodiment, a hole and a circular groove are opened on the top of the shell 1, and a circular protrusion is provided on the inner top of the shell 1, and a cavity is opened inside the circular protrusion.

[0031] The circular groove on the top of the housing 1 can accommodate the turntable 8 to rotate inside, and the scale of the turntable 8 can be observed through the hole on the top of the housing 1.

[0032] In this embodiment, the front and rear parts of the housing 1 are provided with sliding grooves, and the outer side of the bottom is provided with four arc-shaped protrusions.

[0033] The housing 1 limits the ring 4 by means of four arc-shaped protrusions, so that the ring 4 can only rotate in the original position.

[0034] In this embodiment, the inner side of the ring 4 is provided with threads, and the outer side of the threaded block 6 is also provided with threads.

[0035] By rotating the ring 4 , the pressing block 5 can be controlled to rise or move downward, thereby controlling the pressure at the bottom of the pressing block 5 .

[0036] In this embodiment, a cylindrical protrusion is provided at the bottom of the rotating disk 8 , a scale line is provided at the top of the rotating disk 8 , and a round hole is opened at the top of the pressing block 5 .

[0037] The turntable 8 is connected to the worm gear 13 via a bottom protrusion. The worm gear 13 rotates while driving the turntable 8 to rotate, thereby causing the scale observed through the housing 1 to change.

[0038] It should be noted that the utility model is an arterial wound compression device after cardiovascular intervention. When in use, the compression force on the artery can be observed and adjusted. The specific implementation method is to align the bottom center of the lifting block 14 with the center of the wound and compress it, and then fix the device to the patient's body through the strap 2. During the fixing process of the device, the bottom of the pressing block 5 will contact the patient's body, and then the ring 4 will be rotated. While the ring 4 rotates, it will drive the threaded block 6 to rise and fall through the action of the thread. When the threaded block 6 rises and falls, it drives the pressing block 5 to move synchronously. While the pressing block 5 moves, the rope spring 10 is pulled to stretch it. According to Hooke's According to the principle of the law, within the elastic deformation range of the spring, the stretched length is proportional to the tensile force received, so the pressure received by the pressure block 5 can be measured by the stretched distance of the large spring 10. When the pressure block 5 moves, it drives the rack 9 to move, and when the rack 9 moves, it drives the gear 11 to rotate, and the gear 11 drives the worm 12 to rotate, and the worm 12 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the turntable 8 to rotate. After the turntable 8 rotates, the scale of the turntable 8 is observed through the hole on the top of the housing 1 to read the scale, so as to understand the pressure received by the bottom of the pressure block 5. By rotating the turntable 8, the pressure of the compression wound can be adjusted by raising or lowering the pressure block 5.

[0039] By turning the knob 7, the knob 7 will move along its own axis under the action of the thread while turning, and will drive the latch 16 to move synchronously while moving. The latch 16 is controlled by the knob 7 to move toward the lifting block 14, and one side of the inclined surface of the latch 16 will be inserted into the groove of the lifting block 14, and the lifting block 14 will be squeezed to move downward. When the lifting block 14 moves downward, its bottom will extend from the bottom of the pressing block 5, so that the position where the patient contacts the bottom of the lifting block 14 is subjected to greater pressure. By concentrating the pressure more on the position of the wound, the damage to other arteries or veins of the patient due to squeezing can be reduced.

[0040] By setting up the adjustment mechanism 3, the wound compression device can accurately observe the compression force applied to the patient's wound, so that medical staff can specifically adjust the pressure of the wound according to the pulse pressure of different patients, and can concentrate the pressure on the wound site through the lifting block 14, thereby reducing the risk of damage to other arteries and veins of the patient.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
