Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood pressure cuff anti-falling device. Background Art

[0002] A blood pressure cuff is a medical device used to measure blood pressure. It measures blood pressure by inflation and deflation. A blood pressure cuff usually consists of an inflatable bag and a pressure sensor. When measuring blood pressure, the cuff will inject air into the bag through a device to inflate the cuff. When the bag is inflated to a certain degree, it will begin to compress the artery, causing the artery to be blocked. At this time, the pressure sensor can sense the pressure of the artery and transmit the pressure signal to the blood pressure measurement equipment, such as a monitor, sphygmomanometer, etc., to complete the blood pressure measurement.

[0003] When tying the cuff, it is necessary to pay attention to adjusting the tightness of the cuff to a degree that one or two fingers can be inserted. A cuff that is too tight or too loose will affect the measurement results. However, when used at home, it is mostly operated by the user alone and can only tie the cuff with one hand. It is inconvenient to use fingers to measure the tightness of the cuff when tying the cuff. The user can usually only determine the tightness of the cuff by feeling, which leads to large errors in the measurement results due to different tightness of the cuff. At the same time, the lining of the blood pressure cuff is relatively smooth. During the measurement process, if the user's arm used for measurement has a large movement, the cuff is at risk of moving or even falling off, which is not conducive to the accuracy of blood pressure detection. Therefore, the present application provides a blood pressure cuff anti-falling device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a blood pressure cuff anti-falling device to solve the problem that it is inconvenient to use fingers to check the tightness of the cuff when binding the cuff with one hand, and the cuff lining is too smooth and easy to fall off.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A blood pressure cuff anti-detachment device comprises a cuff body and a pressure airbag arranged inside the cuff body for compressing an artery. The inner wall of the cuff body is fixedly connected to a detection structure, which is communicated with the pressure airbag.

[0007] Optionally, the cuff body is made of double-layer fabrics with a cavity in the middle, and the pressure airbag is placed in the cavity of the cuff body.

[0008] Optionally, the detection structure is fixedly connected to the inner fabric of the cuff body and is connected to the pressure airbag through the fabric.

[0009] Optionally, the detection structure includes a detection airbag fixedly connected to the cuff body, the detection airbag is in a closed ring shape and the center thereof coincides with the position of the pressure airbag.

[0010] Optionally, a connecting tube is fixedly connected to the side wall of the detection airbag. Preferably, there are two groups of connecting tubes that are centrally symmetrically distributed, and the other end of the connecting tube is connected to the pressure airbag.

[0011] Optionally, the side wall of the detection airbag is further provided with an exhaust valve, and the exhaust valve is close to the inner wall of the cuff body.

[0012] Optionally, an anti-slip zone is provided in the middle of the detection airbag, the anti-slip zone is made of a thin layer of rubber, and the detection airbag is made of a thick layer of rubber.

[0013] Optionally, one-way valves are fixedly connected to both ends of the pressure airbag, and two groups of the one-way valves are correspondingly and sealedly connected to two groups of the connecting pipes.

[0014] Optionally, one side of the pressure airbag is fixedly connected to an inflation tube, and one end of the inflation tube away from the pressure airbag is fixedly connected to the inflation bag.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, the detection airbag is set to effectively replace the finger detection of the tightness of the cuff binding, which is convenient for one person to operate with one hand, reduces the difficulty of adjusting the tightness of the cuff during self-testing, reduces the error caused by inappropriate cuff tightness, and thus improves the accuracy of the measurement results.

[0017] By setting an anti-slip zone on the detection airbag and utilizing the difference in elastic modulus between the anti-slip zone and the detection airbag, the detection airbag used for measurement can be made to stick to the user's skin after expansion. After the detection airbag is deflated, the anti-slip zone contracts and squeezes the skin, so that the anti-slip zone is adsorbed on the skin, effectively increasing the stability of the cuff. At the same time, the friction between the anti-slip zone and the skin is large, which effectively prevents the cuff from sliding on the arm, further increasing the stability of the cuff and preventing the cuff from shifting or falling off.

[0032] like Figures 1 to 5 As shown, an embodiment of the utility model provides a blood pressure cuff anti-detachment device, including a cuff body 1 and a pressure airbag 2 arranged inside the cuff body 1 for compressing the artery, an inflation tube 4 is fixedly connected to one side of the pressure airbag 2, and an inflation tube 4 is fixedly connected to the end of the inflation tube 4 away from the pressure airbag 2. A detection structure 3 is fixedly connected to the inner wall of the cuff body 1, and the detection structure 3 is communicated with the pressure airbag 2. The cuff body 1 is made of double-layer fabric with a cavity in the middle, and the pressure airbag 2 is placed in the cavity of the cuff body 1. The detection structure 3 is fixedly connected to the inner layer of the fabric of the cuff body 1 and is connected to the pressure airbag 2 through the fabric. The detection structure 3 includes a detection airbag 7 fixedly connected to the cuff body 1, and the detection airbag 7 is a closed ring and the center coincides with the position of the pressure airbag 2.

[0033] like Figure 2 and Figure 4As shown, the side wall of the detection airbag 7 is fixedly connected with a connecting tube 8. Preferably, there are two groups of connecting tubes 8 and they are symmetrically distributed in the center. The other end of the connecting tube 8 is connected to the pressure airbag 2. The detection airbag 7 is communicated with the pressure airbag 2 through the connecting tube 8, so that the gas in the pressure airbag 2 can enter the detection airbag 7 to expand it. When the cuff body 1 is tied to the user's arm, the inflated detection airbag 7 will occupy a certain space. When the binding is completed, the gas in the detection airbag 7 is discharged, and the vacant space can be used for detection. By setting up the detection airbag 7, the finger detection of the tightness of the cuff binding is effectively replaced, which is convenient for one person to operate with one hand. The side wall of the detection airbag 7 is also provided with an exhaust valve 9. The exhaust valve 9 is close to the inner wall of the cuff body 1. The exhaust valve 9 extends to the edge of the cuff body 1 through a hose separated from the detection airbag 7, and is even exposed to the outside of the cuff body 1, so as to facilitate opening or closing the exhaust valve 9 and avoid the exhaust valve 9 contacting the user during use and causing discomfort.

[0034] like Figure 4 and Figure 5 As shown, an anti-slip zone 10 is provided in the middle of the detection airbag 7. The anti-slip zone 10 is made of a thin layer of rubber, and the detection airbag 7 is made of a thick layer of rubber. The anti-slip zone 10 is connected to the detection airbag 7 by hot-melt technology and becomes a whole. However, the elastic modulus of the anti-slip zone 10 is smaller than that of the detection airbag 7. When the detection airbag 7 expands and deforms, the deformation degree of the anti-slip zone 10 is greater. When the cuff body 1 is bound to the user's arm, the anti-slip zone 10 is close to the user's skin and contacts the user over a large area. When the detection airbag 7 is exhausted, the anti-slip zone 10 begins to shrink, squeezing the contacted skin, so that the anti-slip zone 10 is adsorbed on the skin, effectively increasing the stability of the cuff and preventing The friction between the detachment zone 10 and the skin is relatively large, which effectively prevents the cuff from sliding on the arm, further increases the stability of the cuff, and prevents the cuff from shifting or falling off. The two ends of the pressure airbag 2 are fixedly connected with a one-way valve 6, and the two groups of one-way valves 6 are respectively sealed and connected to the two groups of connecting pipes 8. The one-way valve 6 is a one-way airflow valve that can pass through. The airflow can only enter the detection airbag 7 from the pressure airbag 2. When the air pressure in the pressure airbag 2 reaches a certain level, the one-way valve 6 can be automatically opened, so that the gas in the pressure airbag 2 enters the detection airbag 7 through the connecting pipe 8, but the gas in the detection airbag 7 cannot re-enter the pressure airbag 2 and can only be discharged through the exhaust valve 9 on the detection airbag 7.

[0035] Finally, the inflatable bag 5 is pressed again to inflate the pressure bag 2, and the measurement is completed.

[0036] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
