The taper cuff
Technical field
This utility model provides a kind of medical appliance, especially a kind of cuff for sphygomanometer.
Background technology
At present, hyperpietic's quantity of China constantly increases.Along with the raising of common people's self health consciousness, the measurement of blood pressure is from doctor, nurse, extends to that the patient tests oneself, family members measure and the colleague measures.Existing non-invasive blood pressure measurement has upper arm measurement method and wrist formula measurement method.In the operating process of upper arm measurement method, patient is difficult for realizing introspection, will take off upper garment in the winter time, and is very inconvenient.Though wrist formula measurement method is easy to operate, be subject to the chi radius and disturb, can't measure when wrist is thick or thin.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of taper cuff, to improve convenience and the accuracy of blood pressure measurement.
This utility model is to realize like this, the taper cuff, it has the cuff lamellar body, the bottom that the top of cuff lamellar body is arcuation, cuff lamellar body also is arcuation, following length is greater than the top, and the side of cuff lamellar body is hypotenuse, in a side of cuff lamellar body air bag is arranged fixedly, be communicated with the turnover trachea on the air bag, cuff lamellar body both sides have hook face or the hair side of velcro respectively.
Adopt the taper cuff of said structure, simple and reasonable, can measure blood pressure at patient's forearm, easy to operate, the patient can test oneself, and measurement result is accurate, is not subjected to the influence of patient's forearm thickness.
Description of drawings
Fig. 1 is the sketch map of this utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies this utility model.
As shown in drawings, the taper cuff of this utility model, it has cuff lamellar body 7, the bottom 6 that the top 1 of cuff lamellar body is arcuation, cuff lamellar body also is arcuation, following length is greater than the top, and the side 5 of cuff lamellar body is hypotenuse, in a side of cuff lamellar body air bag 4 is arranged fixedly, be communicated with turnover trachea 3 on the air bag, cuff lamellar body both sides have hook face or the hair side of velcro 2 respectively.
This cuff is fan-shaped under the deployed condition, and user mode is tapered.The length of top about 31.5 centimetres, following length about 40 centimetres, the length of side is about 14 centimetres.Air bag is fan-shaped accordingly with the cuff lamellar body, and its length is 16-18 centimetres, and width is about 12 centimetres.
During use, the turnover trachea on this cuff is identical with existing sphygomanometer with the connected mode of air bag, sphygomanometer display device.During measurement, top, the top that the bottom of this cuff is in patient's forearm is in the bottom of patient's forearm, and the concrete operations mode is similar to existing upper arm measurement method, no longer describes in detail.
