ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a blood pressure cuff for a sphygmomanometer, and more particularly, the present invention relates to a blood pressure cuff which is adapted for being used in an independent-measurement type sphygmomanometer.
2. Description of the Related Art
The human body performs metabolism through blood, and therefore, it is necessary to frequently measure a blood pressure to confirm a condition of one's health. Generally, the term ‘blood pressure’ means an arterial blood pressure of the brachial artery.
The conventional blood pressure measuring method is typically implemented by wrapping a blood pressure cuff around the upper arm containing an artery, inflating the blood pressure cuff to a predetermined pressure thereby to occlude the artery, gradually reducing the pressure to allow increased blood flow through the artery, and measuring blood pressures at the times when the Korotkov sounds are generated and vanished as blood flow is restarted in the brachial artery thereby to determine a maximum blood pressure and a minimum blood pressure.
An electronic sphygmomanometer is a device in which an air bag is inflated with air supplied from an air pump to occlude the brachial artery and the air is deflated from the air bag to the outside to depressurize the air bag, and times when the Korotkov sounds are generated and vanished and blood pressures at that times are measured to render numerical expressions, thereby enabling blood pressure measurement to be conveniently carried out.
Referring to
FIG. 1
, there is shown a perspective view illustrating a construction and usage of a blood pressure cuff for a dependent-measurement type sphygmomanometer of the conventional art, which is most widely used. The blood pressure cuff
11
includes an air bag (not shown). The air bag is disposed in the blood pressure cuff
11
and is connected via an air hose
15
to a main body (not shown) of the sphygmomanometer. The blood pressure cuff
11
has a shape of an elongate rectangle. A Velcro brand hook and loop fastener strip
13
and a complementary Velcro brand hook and loop fastener strip
14
are secured to both ends of the blood pressure cuff
11
, respectively, thereby enabling the blood pressure cuff
11
to be firmly attached to the upper arm U of the human body M.
The blood pressure cuff
11
constructed as mentioned above and shown in
FIG. 1
can be used with no problem in the case that it is attached to the upper arm U of the human body M by a separate measurer M′.
However, recently, as an independent-measurement type sphygmomanometer is widely distributed as being an electronic sphygmomanometer, the blood pressure cuff
11
as shown in
FIG. 1
suffers from defects in that it is difficult for a user to independently and personally attach the blood pressure cuff
11
to the upper arm U of one arm with the hand of the other arm.
To cope with this problem, for an independent-measurement type sphygmomanometer, a blood pressure cuff
21
as shown in
FIG. 2
is used. A D-ring R is provided to one end of the blood pressure cuff
21
, and an attachment tab
22
is formed at the other end of the blood pressure cuff
21
. A Velcro brand hook and loop fastener strip
23
is secured to the attachment tab
22
, and a complementary Velcro brand hook and loop fastener strip
21
a is secured to an outer surface of the blood pressure cuff
21
. In the blood pressure cuff
21
constructed as mentioned above, a user inserts his one hand H into a loop, as shown in
FIG. 2A
, which is defined by the fact that the attachment tab
22
is passed through the D-ring R, and then, the blood pressure cuff
21
is raised to the upper arm U using the other hand H′.
Thereafter, as shown in
FIG. 2B
, the attachment tab
22
is pulled by the other hand H′ and is folded back to engage the Velcro brand hook and loop fastener strip
23
with the complementary Velcro brand hook and loop fastener strip
21
a,
thereby to complete the attachment of the blood pressure cuff
21
to the upper arm U.
Then, as shown in
FIG. 2C
, air is supplied via an air hose
24
into an air bag A disposed in the blood pressure cuff
21
, from an air pump (not shown) of a main body of the independent-measurement type sphygmomanometer, thereby pressing the upper arm U to occlude the artery.
However, since a pressure of air supplied into the air bag A must have an extent to block blood flow in the brachial artery, it causes the human body M to experience compression which leads to pain. Also, because the D-ring R is made of metal having substantial rigidity, considerably large deformation stress is induced therein. As a result, the independent-measurement type sphygmomanometer is still encountered with a problem in that the D-ring R can be deformed or detached from the blood pressure cuff
21
and the blood pressure cuff
21
can cause pain or stress to the user thereby preventing an accurate blood pressure measurement from being obtained.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a blood pressure cuff for a sphygmomanometer, which does not cause pain or stress to a user thereby not inducing an inaccurate blood pressure measurement and is not likely to be damaged thereby improving its durability.
In order to achieve the above object, according to one aspect of the present invention, there is provided a blood pressure cuff for a sphygmomanometer, adapted for attachment to the upper arm of a user to effect blood pressure measurement for the user, the blood pressure cuff comprising: an air bag disposed in the blood pressure cuff which has both ends coupled with each other to define a closed loop; an attachment tab extending from a side of the blood pressure cuff; a Velcro brand hook and loop fastener strip secured to a surface of the attachment tab; and a complementary Velcro brand hook and loop fastener strip secured to an outer surface of the blood pressure cuff such that it can be engaged with the Velcro brand hook and loop fastener strip.
By the features of the present invention, the blood pressure cuff can be attached to the upper arm of a user by the fact that the user fits the blood pressure cuff around the upper arm of himself, pulls the attachment tab and engages the Velcro brand hook and loop fastener strip with the complementary Velcro brand hook and loop fastener strip.
Therefore, the blood pressure cuff according to the present invention provides advantages in that since a D-ring made of metal is not used, possibility for the D-ring to be deformed or detached from the blood pressure cuff is eliminated in advance and irregularity of blood pressure due to pain or stress is not caused, whereby convenience and reliability in use and accuracy of a blood pressure measurement operation are ensured.
