Detailed ways

Embodiments of the utility model will be further described below in conjunction with the accompanying drawings.

Example:

As shown in Figures 1 to 4, the embodiment of the utility model provides a hemostatic compressor, including a connecting plate 1, an observation window 5 is provided at the center of the connecting plate 1, and a The compression sheet 6 on the bottom surface, the two ends of the connecting plate 1 are all fixedly installed with a vertically downward support 2, so that the wrist can be placed on the position between the two supports 2, and the opposite surfaces between the two supports 2 are provided with Two guide grooves 3, between the two guide grooves 3, there is a Velcro connection belt 4 that can be glued and merged at both ends, so that the Velcro connection belt 4 can pass through the guide groove 3 and then merge to form Can support the state of the wrist, so that the wrist can be relaxed and placed, the first sliding bar 8 and the second sliding bar 9 vertically upward are fixedly installed on both sides of the compression sheet 6, and both sides of the observation window 5 are equipped with Open the sliding port 7 on the connecting plate 1, and the first sliding rod 8 and the second sliding rod 9 slide on the inner walls of the two sliding ports 7 in one-to-one correspondence, and the two sliding ports 7 are arranged oppositely so that the first sliding rod 8 And the second slide bar 9 has relatively balanced stability, the top of the second slide bar 9 away from the side of the observation window 5 is fixedly connected with a threaded sliding sleeve 11 through the guide bar 10, the second slide bar 9 and the guide bar 10 form a L shape, the guide rod 10 can limit the second slide rod 9 when moving down, the inner wall of the threaded sliding sleeve 11 is screwed with a screw 12 that rotates on the connecting plate 1, and the threaded sliding sleeve 11 is located on the guide rod 10 At the protruding end, the screw mandrel 12 can be rotated away from the observation window 5 without affecting the observation environment.

The working principle of the above technical solution is as follows:

When using the device, pass the velcro connecting belt 4 through the guide groove 3 on the surface of the two brackets 2, and then use the velcro part to stick the velcro connecting belt 4 at both ends to form a semi-arc supportable shape. Then put the wrist on the upper surface of the Velcro connection belt 4 between the two brackets 2, observe the puncture opening from the observation window 5, ensure that it is located at a position away from the center of the observation window 5, and then turn the screw mandrel 12 to make the threaded sliding sleeve 11 and the rotating screw 12 produce a screw transmission, and the threaded sliding sleeve 11 in the transmission state will make the second sliding rod 9 slide down on the inner wall of the sliding port 7. When the second sliding rod 9 moves down, the other The first sliding rod 8, which is also fixedly connected to the compression piece 6 in the sliding port 7, will also move downward together, thereby realizing that the compressive force can compress the femoral artery puncture site from the outside, and can promote the hemostasis and healing of the puncture site. The device can be set to Make the wrist naturally placed on the upper surface of the Velcro connection belt 4, and then push down and press the compression piece 6 to form a resisting state, so that the blood circulation in the wrist will not be blocked, and at the same time, adjust the compression position of the compression piece 6 to be in the connection One side of the observation window 5 of the plate 1, while the screw rod 12 and the compression piece 6 are respectively located on the upper and lower sides of the connecting plate 1, and will not touch the compression piece 6 and the sheath due to adjustment.

In another embodiment, as shown in FIG. 1 , FIG. 2 and FIG. 4 , a bump 16 is fixedly installed on the top of the screw rod 12 , so that the screw rod 12 can be operated better when the screw rod 12 rotates. The joint is fixedly connected with a stopper 17, which can prevent the threaded sliding sleeve 11 from breaking away from the screw mandrel 12 when it moves up and resets. The scale plate 15 fixed on the upper surface of the connecting plate 1 can record the correct scale when using the compression sheet 6, which is convenient to check the records when the same person is followed up.

By setting the scale plate 15 on the rear side of the screw rod 12, the scale on the surface of the scale plate 15 corresponding to the guide rod 10 can be observed after the compression piece 6 is advanced, so that the patient can use the device quickly and accurately when returning to the clinic for treatment, and improve The practical effect of the device.

In another embodiment, as shown in FIG. 2, the connecting plate 1 is provided with a mounting groove 13, the inner wall of the mounting groove 13 is fixedly equipped with the outer ring of the bearing 14, and the bottom end of the screw rod 12 is fixedly mounted on the inner ring of the bearing 14. The screw mandrel 12 can be fixed at a rotatable position, which can maintain stability.

By arranging the bearing 14 to fix the screw rod 12, the rotation of the screw rod 12 can be stabilized, and at the same time, the wear caused by the screw rod 12 being directly connected to the connecting plate 1 in rotation can be avoided.

In another embodiment, as shown in FIG. 2 , a blocking piece 21 is fixedly installed on the top of the first sliding rod 8 , and the diameter of the blocking piece 21 is larger than the diameter of the sliding opening 7 , and it can move down completely when the first sliding rod 8 Hang on the upper surface of connecting plate 1 afterward.

By arranging the blocking piece 21 to be fixed on the top surface of the first slide bar 8, the downward movement of the first slide bar 8 can be limited, preventing the first slide bar 8 from slipping directly when the second slide bar 9 moves down.

In another embodiment, as shown in FIG. 3 and FIG. 4 , the protruding block 16 is provided with a slot 18, and the side of the scale plate 15 close to the top of the protruding block 16 is provided with a limiting groove 19, and an extending slot 18 is inserted inside the slot 18. To the limit bolt 20 inside the limit groove 19, the slot 18, the limit groove 19 and the limit bolt 20 are all pentagonal, and the corners have resistance, which is convenient for the limit to enhance stability.

By setting the limit bolt 20 through the slot 18 and the limit groove 19 in sequence, the screw rod 12 can be limited when it is rotated to the applicable state, so as to prevent the threaded sliding sleeve 11 from moving up due to automatic rotation, thereby affecting the compression of the compression piece 6. compression stability.

In another embodiment, as shown in FIG. 1 , brackets 22 are fixedly installed at the bottom ends of the two brackets 2 .

By providing the bracket 22, the support 2 can be more stable when supported.

The above examples only express the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be interpreted as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
