Description

Technical Field

[0001] The utility model relates to the technical field of the airbag structure of a sphygmomanometer, and more specifically, it relates to an airbag structure of a sphygmomanometer. Background Art

[0002] At the current technical level, there are certain limitations in the airbag structures adopted by many sphygmomanometers. During use, the airbag structures of these sphygmomanometers often cannot adjust their maximum pressure values. This means that regardless of the arm circumference or blood pressure of the patient, the pressure of the airbag will be fixed at a preset level. This design ignores individual differences, which may cause excessive pressure and discomfort to some patients, while for other patients, accurate blood pressure readings may not be obtained.

[0003] In addition, the adjustment of the existing airbag structure of the sphygmomanometer during the pressure relief process is not convenient enough. After the measurement is completed, the airbag needs to relieve pressure to release the compression on the arm, but many devices lack a simple and easy-to-use pressure relief adjustment mechanism. This results in the difficulty of controlling the pressure relief speed and degree. Sometimes it may be too fast, causing discomfort to the patient, and sometimes it may be too slow, prolonging the measurement time and affecting the use experience and efficiency.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an airbag structure of a sphygmomanometer, which has the following features:

[0017] Beneficial effects:

[0018] 1. The design of the adjustment mechanism allows the user to adjust the maximum pressure of the airbag as needed. By turning the pull plate, the relative positions of the limit tube and the adjustment sleeve change, thereby changing the tension of the tension spring, thereby adjusting the sealing force between the fitting plate and the one-way plate. This design enables the user to accurately set the maximum pressure of the airbag according to different measurement requirements or the patient's specific conditions, ensuring the accuracy of the measurement results and reducing the discomfort caused by improper pressure.

[0019] 2. The pressure relief mechanism achieves fine control of the airbag pressure through the coordinated action of the pressure plate, spring, sealing block and guide plate. When pressure relief is required, the sealing block moves downward by pressing the pressure plate, releasing the seal with the pull tube, allowing the gas in the airbag to be discharged through the guide plate and the pull tube. This design allows the user to perform a single small amount of pressure relief, thereby providing more precise control during the measurement process and avoiding measurement errors or patient discomfort that may be caused by a one-time complete pressure relief.

[0020] 3. The sealing mechanism ensures the airtightness of the airbag structure during measurement through the cooperation of the sealing sleeve, push sleeve, and top ring. When continuous sealing is required, the threaded connection between the threaded sleeve and the threaded ring seals the air outlet pipe and presses on the fitting disc, thus ensuring the sealing of the one-way pipe. This design effectively prevents the leakage of gas in the airbag during measurement, ensures the accuracy and consistency of the measurement results, and improves the safety and reliability of equipment operation.

[0030] Please refer to Figures 1-5 a balloon structure of a sphygmomanometer, which includes a balloon body 1. An adjusting mechanism is provided on the balloon body 1. The adjusting mechanism includes a one-way tube 2, an air release tube 3, an air outlet tube 4, a pressure relief mechanism, a sealing mechanism, a pull tube 5, a spring 6, a pressure plate 7, a push rod 8, a guide piece 9 and a sealing block 10.

The pressure relief mechanism and the sealing mechanism are respectively installed on the one-way tube 2. The pull tube 5 is cooperatively connected to the pressure relief mechanism. The pressure plate 7 is installed on the push rod 8. Two ends of the spring 6 are respectively connected to the pressure plate 7 and the pull tube 5. A plurality of guide pieces 9 are provided, and the plurality of guide pieces 9 are respectively installed in the pull tube 5. The push rod 8 is slidably connected between the plurality of guide pieces 9. The sealing block 10 is installed on the push rod 8, and the sealing block 10 is slidably connected in the pull tube 5. The pressure relief mechanism includes a fitting disc 11, a one-way plate 12 and a pull disc 13. The one-way plate 12 is installed in the one-way tube 2. The fitting disc 11 is installed on the pull tube 5. The fitting disc 11 presses on the one-way plate 12. The pull disc 13 is installed on the pull tube 5. A limit tube 14 is provided on the fitting disc 11. A limit sleeve 15 is slidably provided on the limit tube 14. A pull spring 16 is provided on the fitting disc 11. The pull spring 16 is sleeved on the limit tube 14, and the pull spring 16 is connected to the limit sleeve 15. An adjusting sleeve 17 is provided on the limit sleeve 15.

A top ring 20 is coaxially provided in the one-way tube 2. The push sleeve 19 is slidably connected in the top ring 20. A threaded sleeve 21 is provided on the sealing sleeve 18. A threaded ring 22 is provided on the one-way plate 12.

[0031] In this embodiment, since the balloon body 1 is connected to the sphygmomanometer, when it is necessary to adjust the maximum pressure, first rotate the pull disc 13. Since the limit tube 14 is slidably connected in the limit sleeve 15, the adjusting sleeve 17 will be driven to rotate along the one-way tube 2. The adjusting sleeve 17 is threadedly connected in the one-way tube 2, so the position between the adjusting sleeve 17 and the one-way plate 12 will be changed. Since two ends of the pull spring 16 are respectively connected to the fitting disc 11 and the limit sleeve 15, the tension of the pull spring 16 will be changed, thereby changing the sealing force between the fitting disc 11 and the one-way plate 12, and further completing the adjustment of the pressure. When continuous sealing is required, only need to threadedly connect the threaded sleeve 21 to the threaded ring 22, so the air outlet tube 4 can be sealed, and the threaded sleeve 21 is pressed on the fitting disc 11, thus ensuring the sealing of the one-way tube 2.

[0032] More specifically, when a small amount of pressure relief is required at one time, first press on the pressure plate 7, which will counteract the thrust of the spring 6, and then cause the sealing block 10 to slide downward. The sealing block 10 releases the seal with the pull tube 5, and then the gas in the airbag body 1 will be discharged through the plurality of guide pieces 9 and the pull tube 5. When sealing is required, release the pressure plate 7, and then the sealing block 10 will retract into the pull tube 5 under the action of the spring 6, and then the sealing process is carried out.

[0033] In summary, when the overall device is in use or operation: Since the airbag body 1 is connected to the sphygmomanometer, when the maximum pressure needs to be adjusted, first rotate the pull plate 13. Since the limit tube 14 is slidably connected in the limit sleeve 15, it will drive the adjustment sleeve 17 to rotate along the one-way tube 2. The adjustment sleeve 17 is threadedly connected in the one-way tube 2, so the position between the adjustment sleeve 17 and the one-way plate 12 will be changed. Since the two ends of the tension spring 16 are respectively connected to the fitting plate 11 and the limit sleeve 15, the tension of the tension spring 16 will be changed, thereby changing the sealing force between the fitting plate 11 and the one-way plate 12, and thus completing the pressure adjustment. When continuous sealing is required, only thread the threaded sleeve 21 onto the threaded ring 22, so that the air outlet pipe 4 can be sealed, and the threaded sleeve 21 is pressed on the fitting plate 11, thereby ensuring the sealing of the one-way tube 2.

[0034] When a small amount of pressure relief is required at one time, first press on the pressure plate 7, which will counteract the thrust of the spring 6, and then cause the sealing block 10 to slide downward. The sealing block 10 releases the seal with the pull tube 5, and then the gas in the airbag body 1 will be discharged through the plurality of guide pieces 9 and the pull tube 5. When sealing is required, release the pressure plate 7, and then the sealing block 10 will retract into the pull tube 5 under the action of the spring 6, and then the sealing process is carried out.
