Background Art

A sphygmomanometer is a medical device used to measure human blood pressure. It usually consists of a cuff and a blood pressure monitor. There is an air bag inside the cuff and Velcro on the outside. When using a sphygmomanometer, the cuff is usually fixed to the arm with Velcro, and then manually or automatically inflated to apply pressure to the artery in the arm.

When using a blood pressure monitor with a cuff, in order to ensure the accuracy of the measurement, medical staff are usually required to wrap the cuff around the user's arm, fix it with Velcro, and then start the blood pressure monitor body for measurement.

The tension spring 8 is used to drive the support rod 11 to reset. After the measurement is completed, the connecting rod 7 is pulled outward to move the block 14 out of the card slot 12. The tension of the tension spring 8 pushes the support rod 11 upward so that the pressure plate 5 drives the splint 3 to move upward, which is convenient for the splint 3 to reset and the user to take out the arm. The upper end surfaces of the two tension springs 8 are fixedly provided with push plates 18. The two push plates 18 are fixedly provided with support rods 11 on the upper end surfaces, and pressure plates 5 are fixedly provided on the upper end surfaces of the two support rods 11. Clamps 3 are hingedly provided on both sides of the pressure plates 5. The clamps 3 are used to clamp the user's arms to prevent the user's arms from moving during measurement, and can facilitate the use of the auxiliary airbag 4, so that the airbag 4 is conveniently wrapped around the arm. The airbag 4 is fixedly provided between the two clamps 3. The front end surface of the airbag 4 is fixedly provided with a blood pressure meter body 10 at one side. After the fixing is completed, the blood pressure meter body 10 is started to measure the patient's blood pressure. The upper end surface of the support shell 1 is fixedly provided with an arc plate 2 near the lower side of the pressure plate 5;

A fixing rod 6 is fixedly arranged between the end surface of one side of the two limiting shells 15 and the supporting shell 1, and a spring cavity 16 is opened inside the two fixing rods 6 near the two limiting shells 15. A return spring 13 is fixedly arranged inside the two fixing rods 6 near the two spring cavities 16. The return spring 13 is used to drive the clamping block 14 to move toward the direction of the supporting rod 11, so that the clamping block 14 and the clamping groove 12 cooperate with each other to fix the supporting rod 11. A connecting rod 7 is fixedly arranged on the inner side of the two reset springs 13 away from the two limiting shells 15. The two reset springs 13 are fixedly provided with a clamping block 14 near one end of the two limiting shells 15. The clamping block 14 is used to cooperate with the clamping groove 12 to fix the supporting rod 11.

The two limit shells 15 are penetrated by through slots 17 near the two clamping blocks 14. The two clamping blocks 14 penetrate the two fixing rods 6 and the two through slots 17 to the internal positions of the two limit shells 15. The through slots 17 can facilitate the block 14 to enter the inside of the limit shell 15, so as to cooperate with the clamping slot 12 to fix the support rod 11. The arc plate 2 is penetrated by through holes 19 near the two support rods 11. The two support rods 11 penetrate the two limit shells 15 and the two through holes 19 to the arc plate 2. The through hole 19 is used to facilitate the up and down movement of the support rod 11 on the upper side of the shaped plate 2. At the same time, the through hole 19 can limit the moving direction of the support rod 11 to prevent the support rod 11 from tilting left and right. The two support rods 11 are both provided with a card slot 12 near the two card blocks 14. The two card blocks 14 are respectively connected to the internal positions of the two card slots 12. The card blocks 14 are connected to the inside of the card slots 12, which can limit the support rod 11 and facilitate the fixing of the support rod 11, thereby preventing the splint 3 from moving when measuring blood pressure;

The two connecting rods 7 are movably arranged at the internal positions of the two fixed rods 6, so that the connecting rod 7 can be pulled along the inside of the fixed rods 6. The fixed rods 6 are used to limit the position of the connecting rods 7, so that the connecting rods 7 can move. Pulling the pull blocks 9 can drive the connecting rods 7 to move, so that the connecting rods 7 can drive the blocking blocks 14 to move out of the blocking grooves 12. The two support rods 11 are movably arranged with the arc plate 2, so that the two support rods 11 can move up and down along the two through holes 19 inside the arc plate 2, respectively.

Working principle: when in use, put the arm between the two splints 3 on the upper side of the airbag 4 and relax the arm. The weight of the arm will push the splint 3 downward to make the two splints 3 move downward, so that they fit together with the arc-shaped plate 2 on the lower side. When the splint 3 moves downward, it will be restricted and squeezed by the arc-shaped plate 2 to rotate the splint 3, and the upper ends of the splints 3 are close to each other, so that the airbag 4 surrounds the arm. At the same time, when the splint 3 moves downward, it will drive the pressure plate 5 to move the support rod 11 downward, and the two slots 12 are close to the position of the card block 14. The tension of the reset spring 13 drives the card block 14 to be clamped into the inside of the slot 12, so as to fix the support rod 11 conveniently, thereby fixing the splint 3 to prevent the splint 3 from moving during measurement, so as to fix the user's arm conveniently.
