DETAILED DESCRIPTION

[0021] The utility model is further described below:

[0022] See also Figure 1-4 ,

[0023] The utility model discloses a wristband for recording the gas volume of a hemostatic airbag used for radial artery compression hemostasis, comprising a shell 1, a transmission wheel 2, a recording belt 3, a transmission shaft 4, a wristband disc 5 and a wristband belt 6. The shell 1 is a hollow square structure with an opening 7 at the bottom, and through holes 8 for the transmission shaft 4 to pass through are provided on both sides of the front and rear end surfaces thereof. The transmission wheel 2 is arranged on both sides of the inner cavity of the shell 1, and an axial hole 9 for the transmission shaft 4 to pass through is provided in the axial direction of the transmission wheel 2. The outer walls of the transmission wheels 2 on both sides are sleeved with the recording belt 3, and the recording belt 3 is an annular structure made of flexible material, such as rubber, etc. The transmission wheels 2 on both sides tension the recording belt 3, and the outer wall of the recording belt 3 is provided with scale lines 10. The top of the shell 1 is provided with an observation window 11, and the bottom of the shell 1 is connected to the The upper surface of the wristband disk 5 is fixedly connected, and the middle of the two side walls of the wristband disk 5 are respectively connected with the wristband strap 6, and the free ends of the two wristband straps 6 are connected by buckles or magnetic attraction. In this case, when the medical staff extracts a certain amount of gas from the hemostatic airbag each time, the transmission shaft 4 is rotated to drive the transmission wheel 2 and the recording belt 3 to rotate, and the scale line 10 set on the recording belt 3 is used to accurately record the current gas volume in the hemostatic airbag to avoid unnecessary errors; preferably, a timer and a buzzer alarm can be set on the shell 1, and the device for timed alarm by the timer and the buzzer alarm is a prior art, and its working principle will not be repeated here, and it is worn on the hands of medical staff through the wristband disk 5 and the wristband strap 6, so that the medical staff can deflate the hemostatic airbag in time to improve the comfort of the patient.

[0024] Furthermore, the observation window 11 is of a square structure, and the outer wall of the recording tape 3 is located at the rear side wall of the observation window 11, and a plurality of scale lines 10 are provided at equal intervals along the left and right directions; a reading pointer 12 is provided on the upper surface of the shell 1, and the front end of the reading pointer 12 is located at the connection between the right side wall and the rear side wall of the observation window 11, so that medical staff can record the current scale reading more accurately. In the initial state, the rightmost scale line 10 reads 20 ml, which is the maximum gas volume value of the airbag. When the recording tape 3 rotates clockwise, the reading gradually decreases.

[0025] Furthermore, six scale lines 10 are evenly spaced between the left and right walls of the observation window 11, and every six scale lines 10 form an area. A pain level expression mark 13 is provided in front of each area. When the amount of gas in the hemostatic airbag is different, the patient's pain level is different. By setting a pain level expression mark 13 in each area, medical staff can clearly know the current pain level of the patient. Preferably, the pain level expression mark 13 can be set with different colors and expressions according to different pain levels.

[0026] Furthermore, the outer wall of the transmission wheel 2 has a plurality of transmission teeth 14 in a ring array, and the inner wall of the recording tape 3 is evenly spaced with a plurality of driven teeth 15 that match and mesh with the transmission teeth 14, ensuring that the transmission wheel 2 can drive the recording tape 3 to rotate when it rotates.

[0027] Furthermore, a limit block 16 is provided on the middle outer wall of the transmission shaft 4, and a limit slot 17 matching the shape of the limit block 16 is provided on the inner walls of the through hole 8 and the shaft hole 9; by setting the limit block 16 to engage with the limit slot 17 on the shaft hole 9, it can be ensured that when the transmission shaft 4 rotates, the transmission wheel 2 can be driven to rotate with it; further, the length of the limit block 16 is not greater than the length of the shaft hole 9. When in use, it is necessary to ensure that the limit block 16 is fully inserted into the shaft hole 9, and no part of the limit block 16 will stay at the through hole 8, thereby making it impossible for the transmission shaft 4 to rotate.

[0028] Furthermore, a limit ring 18 is mounted on the front and rear sides of the outer wall of the transmission shaft 4, and a limit bolt hole for a limit bolt 19 to pass through is provided on the outer wall of the limit ring 18 and the transmission shaft 4. When the transmission shaft 4 passes through the through hole 8 and the shaft hole 9 in sequence, and the limit block 16 on the transmission shaft 4 is fully inserted into the shaft hole 9, the limit ring 18 is passed through the limit bolt hole by the limit bolt 19 and is fixed with the limit nut. The front and rear limit rings 18 can limit the axial direction of the transmission shaft 4; in addition, the limit bolt holes on the transmission shaft 4 can also play a positioning role. When the distance between the front and rear limit bolt holes and the front and rear sides of the shell 1 is equal to half the thickness of the limit ring 18, it can be ensured that the limit block 16 is fully inserted into the shaft hole 9.

[0029] Furthermore, a rotating ring 20 is fixed to the front end of the outer wall of the transmission shaft 4, and anti-slip grooves are provided on the outer wall of the rotating ring 20, so that medical staff can rotate the rotating ring 20 in time and record the current gas volume of the hemostatic airbag.

[0030] Furthermore, a square-shaped connecting frame 21 is connected to the lower part of the outer wall of the shell 1, and a plurality of bolt holes 22 for connecting bolts to pass through are provided on the connecting frame 21. A threaded hole coaxial with the bolt hole 22 is provided on the edge of the upper surface of the bracelet disk 5. The connecting bolts are threadedly connected with the threaded holes. After the connecting bolts pass through the bolt holes 22, they are threadedly connected with the threaded holes on the bracelet disk 5, which facilitates the quick installation and disassembly of the shell 1 and the bracelet disk 5.
