Abstract

A balloon-less anti-slip blood pressure cuff comprising a cuff body provided with a gas cavity (1). The gas cavity (1) is formed by at least two airtight sheets hermetically connected to each other at the edges. An inflation tube (2) for putting the gas cavity (1) in communication with the external environment is provided on the sheets. A friction element (3) is provided on the surface of the sheets. The cuff uses the hermetically connected sheets to constitute the gas cavity (1), thus changing the scheme in which a blood pressure cuff and a balloon are combined, obviating the need to add a balloon in the cuff, reducing the trouble of manual straightening, making blood pressure tests more accurate and convenient, and increasing efficiency. At the same time, the friction element (3) is provided on the sheets, when the gas cavity (1) is expanded, the friction element (3) comes into contact with the skin of a limb and produces friction, thus preventing the cuff from slipping and falling off.

Description

Airbag non-slip blood pressure cuff

Technical field

The present invention relates to the field of medical devices, and more particularly to a non-balloon anti-skid blood pressure cuff.

Background technique

The existing blood pressure cuffs are provided with airbags, which are mainly composed of airbags with air nozzles, hook and loop fasteners, and PVC cloth bags. The ends of the head and the tail have a female buckle, and the PVC cloth bags are wrapped inside the airbag, and the whole is strip-shaped. The strap is wrapped around the user's arm when it is used, and is bound to the user's arm through the bite cloth at both ends of the head and the tail. However, if the user does not bind with proper force when using it, it is easy to be fixed. The problem of looseness or looseness caused by loosening of the user's blood due to over-tightening, the looseness of the fixation may result in inability to measure and measure inaccurate, and the fixation is too tight, resulting in poor blood circulation, and the user feels uncomfortable. A major flaw in the existing blood pressure cuff.

At the same time, since the airbag and the blood pressure cuff are separated, the airbag is easily combined by the manner of wrapping, and the airbag is prone to displacement and sliding, which is not only troublesome in manufacturing and assembly, but also inconvenience due to sliding and displacement of the airbag in the PVC cloth bag during use. Manual straightening and correction, extremely inconvenient to use, fabric wrinkles affect precision.

Summary of the invention

In order to overcome the above problems, an object of the present invention is to provide an airbag-free anti-slip blood pressure cuff that is accurate and convenient for blood pressure detection.

The technical solution adopted by the invention is:

A non-balloon anti-slip blood pressure cuff includes a cuff body having a gas chamber formed by sealing at least two layers of gas impermeable sheets at edges thereof, the sheet being provided with a gas chamber An inflatable tube that communicates with the outside, and the surface of the sheet is provided with a friction member.

As a further improvement of the present invention, the cuff body includes an extended strip connecting the sheets, The extended strip is the same material as the sheet.

As a further improvement of the present invention, the extension strip is integrally formed with the sheet, and a sealing tape is provided at the joint end of the sheet and the extension strip.

As a further improvement of the invention, the friction member is a rubber strip.

As a further improvement of the present invention, the rubber strip is U-shaped, N-shaped Z-shaped or V-shaped.

As a further improvement of the present invention, one end of the cuff body is provided with a female buckle, and the cuff body is provided with not less than two male buckles in the direction of extension, and the cuff body is wound when the body is wound The female buckle is connected to any male buckle.

The invention has the beneficial effects that the invention uses the sealingly connected sheet to form a gas chamber, changes the combination of the blood pressure cuff and the airbag, eliminates the need to install an airbag in the cuff, reduces the trouble of artificial straightening, and makes blood pressure The detection is more accurate and convenient, and the efficiency is higher. At the same time, the friction member is arranged on the sheet, and after the gas chamber is expanded, the friction member contacts the skin of the limb to generate friction and prevent the sleeve from sliding and falling off.

DRAWINGS

The invention will now be further described with reference to the drawings and embodiments.

Figure 1 is a plan layout view of the first embodiment;

Figure 2 is a plan view of the second embodiment;

Fig. 3 is a plan layout view of the third embodiment.

detailed description

The anti-balloon anti-slip blood pressure cuff shown in FIG. 1 to FIG. 3 includes a cuff body having a gas chamber 1 formed by two layers of gas-impermeable sheets sealed at the edges, and the sheet is arranged on the sheet. There is an inflation tube 2 that communicates the gas chamber 1 with the outside. The gas chamber 1 is equivalent to an air bag, and the degree of expansion of the gas chamber 1 is adjusted by the intake and exhaust of the gas tube 2 to meet the blood pressure detection. need. The gas chamber 1 can also be enclosed by three or more layers of sheets, as long as a closed gas chamber 1 can be constructed.

In the embodiment, the sheet is directly on the cuff body, so that displacement and sliding do not occur, and the gas chamber 1 is not displaced relative to the cuff body, and no manual straightening and correction are required, which is very convenient to use and blood pressure detection. Also more accurate.

A friction member 3 is provided on the surface of one of the sheets for friction with the limb. When the cuff body is wound onto the arm, the friction member 3 comes into contact with the skin, and then inflates into the gas chamber 1, the gas chamber 1 expands, and the friction member 3 presses the skin, and the friction between the two increases. The sheet does not easily slip with the skin.

As a further preferred embodiment, the cuff body includes an extension strip 4 connecting the sheets, and the extension strip 4 is made of the same material as the sheet material, and each has a PE material having a smooth surface and a good hand feeling, and the material has a gas tightness on the one hand. On the other hand, contact with the skin does not cause discomfort.

As a further preferred embodiment, the extension strip 4 is integrally formed with the sheet material, actually extending the strip of the strip 4 and the sheet as a whole, and the extension strip 4 is also two layers, only the strip at the gas chamber 1 The belt edges are sealed and sealed by gluing. At the same time, at the joint end of the sheet and the extension strip 4, a sealing tape 5 is provided which divides the entire strip into the gas chamber 1 on the left side and the extended strip on the right side without filling the gas. 4. Of course, the extension strip 4 on the right side can also be sealed at the edges so that the blood pressure cuff is not too loose.

As a further preferred embodiment, the friction member 3 is a convex rubber strip, and the rubber strip is relatively soft and does not cause discomfort to human skin.

As a further preferred embodiment, the rubber strip is U-shaped as shown in FIG. 1; the rubber strip is N-shaped as shown in FIG. 2; the rubber strip is V-shaped as shown in FIG. 3; in the embodiment not shown, The rubber strip is Z-shaped. The rubber strip of the above shape enables a gap to be formed between the sheet and the arm to ensure blood circulation.

As a further preferred embodiment, one end of the cuff body is provided with a female buckle 6 and a cuff body There are not less than two male buckles 7 in the direction of the extension, and the female buckle 6 is connected to any of the male buckles 7 when the cuff body is wound. The segmented design allows the medical staff to choose to bond the female buckle 6 to different male buckles 7 according to the size of the arm when the blood pressure needs to be detected, without the need to replace or find a new cuff, saving The user's time.

The above is only a preferred embodiment of the present invention, and it is not intended to limit the scope of the present invention.
