[0001] The utility model relates to the technical field of medical devices, and particularly relates to a sphygmomanometer with auxiliary gas filling and exhausting. Background Art

[0002] Sphygmomanometers mainly include auscultatory sphygmomanometers and oscillometric sphygmomanometers. Auscultatory sphygmomanometers are further divided into manual auscultatory sphygmomanometers and automatic auscultatory sphygmomanometers. Mercury sphygmomanometers (pressure gauges) and spring dial sphygmomanometers (pressure gauges) are early manual auscultatory sphygmomanometers. Current manual auscultatory sphygmomanometers include digital sphygmomanometers, light column sphygmomanometers, optical display sphygmomanometers, liquid crystal sphygmomanometers, etc.

Detailed implementation mode

[0020] Embodiment 1

[0021] As Figures 1-4 shown, a sphygmomanometer with auxiliary air filling and exhausting proposed by the present utility model includes an inflatable belt 1, a trachea 2, a micro air pump 3, a sphygmomanometer 4, a hook surface 5 of Velcro, a protection component and an anti-pollution component. The same ends of two juxtaposed tracheas 2 are connected to the inflatable belt 1. The two sides of the inflatable belt 1 are used to connect the hook surface 5 of Velcro. The anti-pollution component is connected to the inflatable belt 1; in the use state, the anti-pollution component contacts the two sides of the inflatable belt 1, preventing the human body or external objects from directly contacting the inflatable belt 1 and thus avoiding the pollution of its surface; the other ends of the two tracheas 2 are respectively connected to the micro air pump 3 and the sphygmomanometer 4.

[0022] In an optional embodiment, a pressure relief pipe 6 is connected to the trachea 2 between the micro air pump 3 and the inflatable belt 1, and a uniform air leakage valve 7 is connected to the pressure relief pipe 6; the uniform air leakage valve 7 can leak air evenly during use to meet the needs of blood pressure measurement.

[0023] The protection component is connected to the outside of the micro air pump 3; in the use state, an accommodation cavity is formed inside the protection component for accommodating the micro air pump 3, and the protection component can also filter the air entering the accommodation cavity to prevent external dust and debris from affecting the normal use of the micro air pump 3.

[0024] Embodiment 2

[0025] As Figures 3-4 shown, a sphygmomanometer with auxiliary air filling and exhausting proposed by the present utility model, compared with Embodiment 1, in this embodiment, the detailed structure of the protection component is described. The protection component includes a fixing plate 8, a moving cylinder 9 and an edge-wrapped filter screen 10. The fixing plate 8 is connected to one end of the micro air pump 3 close to the trachea 2 through an adhesive. The moving cylinder 9 is a hollow structure and is sleeved outside the micro air pump 3. One end of the moving cylinder 9 is detachably connected to the fixing plate 8. A convex block 11 is connected to the inner wall of the other end of the moving cylinder 9. The edge-wrapped filter screen 10 is slidably connected inside the moving cylinder 9 and contacts the convex block 11; one end of the micro air pump 3 and the convex block 11 limit the position of the edge-wrapped filter screen 10, so as to filter the air inlet end of the micro air pump 3.

[0026] In an alternative embodiment, a plurality of limiting posts 12 are connected to the outer wall of the fixed plate 8, and the limiting posts 12 are slidably connected to an L-shaped limiting groove 13 formed in the inner wall of the moving cylinder 9; the sliding of the limiting posts 12 and the limiting groove 13 restricts the movement of the moving cylinder 9 along the central axis direction of the micro air pump 3.

[0027] Embodiment III

[0028] As Figures 1-2 shown, a sphygmomanometer with auxiliary air filling and exhaust proposed by the present utility model, compared with Embodiment II, the detailed structure of the anti-fouling component is described in this embodiment. The anti-fouling component includes a first protective layer 14, a magic tape round plush surface 15, a second protective layer 16 and an auxiliary member 17. One end of the first protective layer 14 and the second protective layer 16 are connected;

[0029] In an alternative embodiment, a notch is formed in the second protective layer 16 to cut it into two sections. Symmetrically arranged arc-shaped blocks 18 are connected to the notch of the second protective layer 16, and the inner wall of the arc-shaped blocks 18 is attached to the air tube 2; the arc-shaped blocks 18 are selected but not limited to rubber layers. The arc-shaped blocks 18 can impose a certain restriction on the folding and bending of the air tube 2, preventing the air tube 2 from being bent at too large an angle, resulting in cracks and air leakage in the air tube 2;

[0030] The opposite sides of the first protective layer 14 and the second protective layer 16 are used to connect the magic tape round plush surface 15, and the magic tape round plush surface 15 is adhesively bonded to the magic tape prickly surface 5 on the air inflation belt 1. The auxiliary component is slidably connected to the first protective layer 14 and the second protective layer 16;

[0031] In an alternative embodiment, the auxiliary member 17 is a U-shaped clip 19, and the U-shaped clip 19 is slidably connected to the air inflation belt 1; the U-shaped clip 19 will also contact the human body when the air inflation belt 1 is wound around the human upper arm. The volume of the U-shaped clip 19 enables the air inflation belt 1 to be neither too tight nor too loose when wound, eliminating the need for staff to adjust the tightness.

[0032] In summary, in the present utility model, when measuring blood pressure, the staff connects the device to an external power supply to supply power to the micro air pump 3. The staff unfolds the first protective layer 14 and the second protective layer 16, and then places the inflatable belt 1 between the first protective layer 14 and the second protective layer 16. The inflatable belt 1 is adhered to the magic hook surface 15 on the side walls of the first protective layer 14 and the second protective layer 16 through the magic loop surface 5 on both side walls of the inflatable belt 1, thereby forming a protective layer for the inflatable belt 1 outside the inflatable belt 1 to prevent the inflatable belt 1 from being contaminated by human sweat and grease. Then, the U-shaped clip 19 is clamped outside the first protective layer 14 and the second protective layer 16. When measuring, the staff winds the inflatable belt 1 around the outside of the human upper arm. When measuring, taking out the U-shaped clip 19 can avoid the inflatable belt 1 being wound too tightly. The staff starts the micro air pump 3 to inflate the inflatable belt 1 to measure blood pressure. After the measurement is completed, uniform air leakage can be carried out by adjusting the valve on the uniform air leakage valve 7. When the micro air pump 3 is working, the inhaled air will be preliminarily filtered by the edge filter screen 10 to prevent external fibers and dust from affecting the normal use of the micro air pump 3. At the same time, the moving cylinder 9 can also protect the micro air pump 3 to prevent it from being damaged.

[0033] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art to which the present utility model pertains.
