A retractable adaptive blood pressure cuff

Abstract

The invention relates to a retractable self-adaptive blood pressure cuff. An airbag cover is a bagging structure with openings at both ends. Belt, the length of the retractable fixing belt is not less than the length of the airbag cover, on the retractable fixing belt is provided with an adhesive hook layer matching with the sticky hair layer, at the edge of the airbag cover outside the sticky hair layer There are two sliding slot holes symmetrically, and sliding bolts are movably installed in each sliding slot hole, and two fixing nuts matching the two sliding bolts are fixedly installed on one side of the end of the telescopic fixing belt. The two sliding bolts are respectively connected to the two fixing nuts through threaded connection; corresponding adjustments are made according to the thickness of the patient's arm, and the operation is simple and easy to ensure reasonable contact between the sticky hook and the sticky hair during measurement. Guarantee the accuracy of measurement quality and final inventory results, and improve the efficiency of measurement.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a retractable self-adaptive blood pressure cuff. Background technique [0002] A sphygmomanometer cuff belongs to the technical field of medical devices and is used for blood pressure measurement. People who have measured blood pressure generally have access to a blood pressure cuff, which is tied to the arm to help read blood pressure data. For hypertensive patients, blood pressure cuffs are used more, whether in the hospital or at home. The blood pressure cuff has two specifications of single tube and double tube. The trachea and inner liner materials are environmentally friendly, non-toxic, odorless, soft materials, and the thickness of the inner liner is 0.3mm, which is reusable and easy to sterilize. [0003] Blood pressure measurement is a relatively routine operation in clinical work, but the current measurement process using traditional blood pressure cuffs has certain defects: ...

Problems solved by technology

[0003] Measuring blood pressure is a relatively routine operation in clinical work, but there are certain defects in the use of traditional blood pressure cuffs in the current measurement process: the length of traditional blood pressure cuffs cannot be adjusted when used, and cannot adapt to different outer diameters of upper arms For all patients, some patients have thicker arms, and some patients have thinner arms. During the measurement, when the thicker patients were fastened with the cuff, due to the limitation of the length of the cuff itself, the binding operation could not even be performed, resulting in the inability to Measuring blood pressure; when used by thinner patients, the cuff is too thick due to the number of winding turns of the cuff, which will also affect the accuracy of the measurement results

In particular, when thicker patients are in use, the sticky hooks and sticky hairs of the cuff cannot be in contact, resulting in the overall cuff not being effectively restrained, resulting in measurement failures that often occur

It is not good if the cuff is too loose or too tight when measuring blood pressure, which will affect the measurement accuracy of the blood pressure monitor.

[0004] The Chinese patent number is: 201020123758.1, which discloses a cuff for a dynamic blood pressure instrument. In order to use different patient arms, an elastic body is provided, which has certain defects in use. The elastic body has elasticity, and the cuff as a whole The length of the cuff still cannot be extended. The specific performance is that when the patient's arm is thick, the cuff of this product will be wrapped too tightly. The measured value is low

This patent realizes the lengthening of the cuff, but in the specific operation, it will be found that the product is not practical. First of all, the operation is more troublesome. When using it, different numbers of lengthening sections should be set according to the thickness of the patient's arm, and The size of the extension section may not exactly meet the thickness and length of the patient's arm. During operation, it is impossible to know whether the length of the cuff is enough without adding it to the patient's arm. Only after adding it to the patient's arm can we know that the cuff length is not enough. , so after wrapping the cuff around the patient's arm, knowing that the length of the cuff is not enough and then adding an extension, the complexity of the operation can be imagined; The hook structure, when added to the patient's arm, will obviously cause discomfort, and it is easy to cause the phenomenon of over-tightening. If the cuff is too tight, the blood vessels will be compressed before the gas is injected, resulting in a low measured value.
