Description

Technical Field

[0001] The utility model belongs to the technical field of metrological verification, and particularly relates to an auxiliary device for metrological verification of sphygmomanometers. Background Art

[0002] A sphygmomanometer is an instrument for observing the human blood pressure by an indirect measurement method in hospitals or families. By measuring two parameters of diastolic blood pressure and systolic blood pressure, it reflects the flow intensity of blood in arterial blood vessels. The measurement of blood pressure can help doctors diagnose blood pressure conditions and evaluate the cardiovascular health status of patients.

[0003] With the improvement of people's living standards, the public's pursuit of health is also more and more refined. Sphygmomanometers are commonly kept at home to observe the blood pressure values of family members at any time, especially for the elderly and patients with chronic diseases. Sphygmomanometers can provide the simplest way to detect health. Therefore, the accuracy of blood pressure values plays a crucial role in the diagnosis of diseases.

[0004] For this reason, China stipulates that sphygmomanometers are compulsory verification measuring instruments and must be compulsorily verified every six months to ensure the accuracy and reliability of their measured values. However, due to their large quantity, all the legal metrological verification institutions of sphygmomanometers in China have to operate under high load. During the verification process, the verification personnel need to press the balloon thousands of times by hand every day, which is extremely likely to cause swelling of the fingers and wrists of the verifiers and even leave occupational diseases.

[0005] Therefore, it is very necessary to design an auxiliary device for metrological verification of sphygmomanometers. Content of the Utility Model

[0006] The purpose of the utility model is to provide an auxiliary device for metrological verification of sphygmomanometers, which can squeeze and inflate the sphygmomanometer balloon placed in the semi-cylindrical groove by pressing down and lifting the upper pressing plate, and can replace the detection personnel to manually press the balloon.

[0007] The technical solution provided by the utility model is as follows:

[0008] A lower support plate, on the upper surface of which a groove is provided;

[0009] An upper pressing plate, one end of which is hinged to one end of the lower support plate, and the lower surface of the upper pressing plate is provided with a pressing block; the position of the pressing block corresponds to the position of the groove, and the shape of the pressing block matches the shape of the groove;

[0010] Wherein, the balloon of the sphygmomanometer to be measured is placed in the groove, and by reciprocally lifting or pressing down the upper pressing plate, the pressing block repeatedly presses the balloon of the sphygmomanometer to be measured.

[0011] Preferably, the lower support plate and the upper pressing plate are hinged by a pin shaft.

[0012] Preferably, the width of the lower support plate is greater than the width of the upper pressing plate.

[0013] Preferably, the width of the pressing block on the lower surface of the upper pressing plate is greater than the width of the upper pressing plate and matches the length of the sphygmomanometer balloon.

[0014] Preferably, the tail of the pin shaft is fixed by a split pin.

[0015] Preferably, a convex anti-slip handle is provided at the end of the upper pressing plate.

[0016] The beneficial effects of the present utility model are as follows:

[0017] The auxiliary device for sphygmomanometer metrological verification provided by the present utility model can replace the tester to manually press the balloon, effectively control the deformation degree of the balloon to be tested, make the verification result more accurate, and at the same time reduce the risk of occupational diseases of the tester's hands.

[0022] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0023] As Figures 1-4As shown in the figure, the utility model provides an auxiliary device for the measurement and verification of sphygmomanometers, including an upper pressing plate 110 and a lower supporting plate 120. The width of the lower supporting plate 120 is greater than that of the upper pressing plate 110 to ensure the stability of the device during the process of lifting or pressing down the upper pressing plate 110. A semi-cylindrical groove 160 is formed on the upper surface of the lower supporting plate 120. One end of the upper pressing plate 110 is hinged to one end of the lower supporting plate 120, and a semi-cylindrical pressing block 150 is provided on the lower surface of the upper pressing plate 110. The width of the pressing block 150 is greater than that of the upper pressing plate 110, and it is generally matched with the length of the common sphygmomanometer balloon. The position of the pressing block 150 corresponds to the position of the groove 160, and the shape of the pressing block 150 matches the shape of the groove 160. By pressing down the upper pressing plate 110, the sphygmomanometer balloon 130 can be squeezed. A convex anti-slip handle 180 is provided at the end of the upper pressing plate, and the thickness of the handle 180 is greater than that of the upper pressing plate 110. Since the positions and shapes of the pressing block 150 and the groove 160 match each other, pressing down the upper pressing plate can make the pressing block coincide with the groove, ensuring that the pressing height is the same each time and the deformation degree of the measured sphygmomanometer balloon 130 is the same. It is applicable to sphygmomanometer balloons of different materials or elasticities, and the verification result is more accurate than manual pressing.

[0024] The upper pressing plate 110 and the lower supporting plate 120 are hinged by a pin shaft 140, and the upper pressing plate can rotate around the pin shaft 140. A pin hole is provided at the tail of the pin shaft 140, and a split pin 170 is inserted into the pin hole to fix the pin shaft 140. The tail of the split pin is bent and wound for fixation to prevent the pin shaft 140 from loosening.

[0025] Lift the upper pressing plate 110 to separate the semi-cylindrical pressing block 150 on its lower surface from the semi-cylindrical groove 160 on the upper surface of the lower supporting plate 120 to an appropriate height. Place the measured sphygmomanometer balloon 130 in the semi-cylindrical groove 160. Press down the upper pressing plate 110 to deform the sphygmomanometer balloon 130 until the semi-cylindrical pressing block 150 is close to coinciding with the semi-cylindrical groove 160. Slowly lift the upper pressing plate 110 to make the sphygmomanometer balloon 130 automatically return to its original state. According to the sphygmomanometer balloons of different elasticities or materials, the lifting or pressing height can be appropriately adjusted. Observe whether the change in the sphygmomanometer reading meets the sphygmomanometer measurement verification standard after repeating many times.

[0026] An auxiliary device for metrological verification of a sphygmomanometer of the utility model can squeeze and inflate the sphygmomanometer balloon placed in the semi-cylindrical groove of the lower support plate by pressing down and lifting the upper pressing plate, so that the semi-cylindrical pressing block on the lower surface of the upper pressing plate can replace the tester to manually press the balloon, effectively reducing the finger and wrist soreness or swelling caused by the tester manually pressing the balloon, and greatly reducing the probability of hand joint diseases or other occupational diseases. In addition, there are many restrictions on manually pressing the balloon, and the deformation degree of the balloon cannot be controlled each time. The utility model can effectively control the same deformation degree of the balloon each time by controlling the height of pressing down the upper pressing plate, and the upper pressing plate is relatively long, so the operation is more labor-saving.

[0027] Although the embodiments of the utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the utility model is not limited to the specific details and the illustrated examples here.
