Description
Technical Field
The invention relates to the field of medical instruments, in particular to a cuff device for blood pressure measurement and ischemia pre-adaptation training.
Background
The change of blood pressure is one of the important indexes reflecting the human circulatory system. The blood pressure is too low, which can cause insufficient blood supply of organs, especially insufficient blood supply of important organs such as heart and cerebral vessels, and can cause serious consequences. When the blood pressure is too high, the heart and blood vessels are overloaded, and compensatory hypertrophy of the heart, cardiovascular insufficiency and even heart failure can be caused. The vessel wall is easily pathologically changed after being pressed by high pressure for a long time, and even serious consequences such as cerebral hemorrhage and the like can be caused. Therefore, it is very necessary to know the self blood pressure accurately in time.
The principle of ischemia pre-adaptation training is that repeated, transient, non-invasive and harmless ischemia pre-adaptation training is carried out on a human body, and an emergency mechanism of the immune system of the human body can be stimulated in the training process to generate and release endogenous protective substances, such as: adenosine, bradykinin, nitric oxide, and the like, which are involved in protecting cardiac muscle and energy metabolism, thereby reducing and resisting subsequent or longer-term damage due to ischemia and hypoxia in humans. The ischemia pre-adaptation training can effectively avoid the occurrence of cardiovascular and cerebrovascular diseases such as cerebral infarction, sudden cardiac death and the like.
The traditional air bag of the sphygmomanometer is a large air bag, covers the upper part of brachial artery, and is used for detecting Korotkoff sounds or collecting signals by an oscillometric method through a stethoscope after the pressurization and decompression processes of the air bag so as to judge the change of the blood pressure. However, conventional bladder designs may cause misalignment, fail to fully function as a compression, or cause uneven compression, resulting in measurement errors averaging 10-20mm Hg. The blood pressure of most of the patients with hypertension is increased within the range of 5-6 or 19-20mm Hg, so the accuracy of the measurement result of the sphygmomanometer has a non-negligible effect on accurately judging the disease condition.
Meanwhile, the cloth used by the cuff of the traditional sphygmomanometer has the defects of poor air permeability, low comfort level, easy bacteria breeding and the like, and the defects are not obvious if the cloth is only used for measuring the blood pressure. However, when used in an ischemia preconditioning training process, bacteria may grow due to a large amount of perspiration due to a long training period.
Disclosure of Invention
The invention aims to provide a cuff device for blood pressure measurement and ischemia pre-adaptation training. The device has the following features: the blood pressure measurement accuracy can be effectively improved; the state of numbness of the old due to ischemia pre-adaptation training can be quickly relieved; the air permeability and antibacterial property of the outer wrapping cloth of the cuff are enhanced.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a cuff device for blood pressure measurement and ischemia pre-adaptation training comprises a cuff, a main airbag and an auxiliary airbag, wherein the main airbag and the auxiliary airbag are parallel to each other and are positioned on the cuff;
the oversleeve is made of cloth comprising an inner layer surface cloth, a middle layer cloth and an outer layer surface cloth; the inner layer surface cloth, the middle layer cloth and the outer layer surface cloth are woven into a whole in a double-sided warp knitting mode by taking far infrared fibers as yarns; the inner layer surface cloth and the outer layer surface cloth are uniformly distributed with air holes; the middle layer cloth is far infrared fiber; the inner layer surface cloth and the outer layer surface cloth are woven by the core-spun yarn formed by blending polyester fiber, polyamide fiber and spandex fiber, and the mass proportion of the polyester fiber in the core-spun yarn is as follows: 42.34-52.14 percent of polyamide fiber, wherein the polyamide fiber accounts for the following mass percent: 20.97-27.44 percent, and the spandex fiber accounts for the following mass percentage: 26.89% -30.22%; the core-spun yarn is soaked in 1-2% of nano-silver solution for 0.5-2min, and is dried for 5-10min at the temperature of 130 ℃ after being taken out;
the far infrared fiber is formed by melting and granulating 8-14% of far infrared powder with the particle size of 2-7 mu m and polyester fiber before spinning, extruding by a screw and winding; the far infrared powder is ZrO2、MgO、SiC、TiB2、MoSi2And TiN.
The main air bag and the auxiliary air bag are positioned on the middle layer cloth.
Furthermore, a plurality of anti-skidding belts are arranged on the inner-layer surface cloth and are positioned on the side face of the main airbag.
Furthermore, two electrode massage pastes are arranged on the inner-layer surface cloth and are respectively positioned on two sides of the anti-slip belts.
Furthermore, be equipped with control unit, pressure sensor, microphone sensor, heart rate sensor on the outer table cloth, microphone sensor, heart rate sensor and pressure sensor all are connected with control unit.
Further, the oversleeve is rectangular.
Further, the core-spun yarn is soaked in a 2% nano silver solution for 2min, taken out and dried at 115 ℃ for 5 min.
Furthermore, the far infrared fiber is formed by melting and granulating far infrared powder with the particle size of 4 mu m and polyester fiber according to the proportion of 11 percent before spinning, extruding by a screw and winding.
Further, the distanceThe infrared powder is composed of SiC and TiB2Composition, SiC and TiB2Respectively adding the mixture into polyester fiber according to the proportion of 4 percent and 7 percent.
Further, the far infrared powder is made of MgO, SiC and MoSi2Composition of MgO, SiC and MoSi2Respectively adding the mixture into the polyester fiber according to the proportion of 3 percent, 4 percent and 4 percent.
Furthermore, the air holes on the inner layer surface cloth and the air holes on the outer layer surface cloth are alternately distributed.
Compared with the prior art, the invention has the following technical effects:
according to the invention, the auxiliary air bag and the anti-skid belt bulge are added, so that errors caused by air bag deviation in the measurement process are effectively prevented; the electrode massage paste is added, so that a human body can quickly recover from a paralyzed state, and the electrode massage paste has a certain health care function; meanwhile, the wrapping cloth of the cuff has good air permeability and antibacterial capability, and effectively avoids breeding bacteria due to sweating.
