DETAILED DESCRIPTION

[0022] Hereinafter, embodiments of the disposable cuff structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4The disposable cuff structure of an embodiment of the utility model is shown, including a cuff base 3 located at the top of the blood pressure detector 1, the top of the cuff base 3 is fixedly connected to two fixing plates 8, the inner cavity of the fixing plate 8 is fixedly connected to a fixing rod 9, the top of the pressure ring 4 is fixedly connected to a connecting piece 10, the connecting piece 10 is rotatably connected to the surface of the fixing rod 9, the front and rear sides of the surface of the fixing rod 9 are sleeved with a torsion spring 11, one end of the torsion spring 11 is buckled with the fixing plate 8, and the other end of the torsion spring 11 is buckled with the connecting piece 10, through the coordinated use of the fixing plate 8, the fixing rod 9 and the connecting piece 10, the pressure ring 4 is twisted. The pressure ring 4 can be actively flipped upward and opened after being unlocked, so that the user can easily put on the disposable cuff 6. A detection arm tube 2 is arranged on the right side of the top of the blood pressure detector 1. The cuff base 3 is fixedly connected to the front side of the detection arm tube 2. A rotatable pressure ring 4 is arranged on the front side of the cuff base 3. An annular groove 5 is provided on the front side of the surface of the cuff base 3 and the left side of the pressure ring 4. The inner cavity of the annular groove 5 is sleeved with a disposable cuff 6. An elastic rope 12 is fixedly connected to the bag mouth of the disposable cuff 6. A reserved seam 13 adapted to the elastic rope 12 is reserved between the cuff base 3 and the pressure ring 4. The elastic cord 12 and the reserved seam 13 are used in combination. After the disposable cuff 6 is unfolded, the elastic cord 12 can pop out from the reserved seam 13, so that the disposable cuff 6 can be put on the patient's arm. A fixing assembly 7 is provided at the bottom of the pressure ring 4. The fixing assembly 7 includes a fixing plate 71 fixedly connected to the bottom of the pressure ring 4. A limiting slide groove 72 is provided on the right side of the fixing plate 71. A limiting pin 74 is provided in the inner cavity of the limiting slide groove 72. The surface of the limiting pin 74 is fixedly connected to a limiting slider 73. The limiting slider 73 is slidably connected to the inner cavity of the limiting slide groove 72. The right side of the bottom of the cuff base 3 is fixedly connected to The limiting card plate 75 and the limiting pin 74 are engaged in the inner cavity of the limiting card plate 75. A spring 76 is welded to the bottom of the limiting slider 73. The bottom end of the spring 76 is welded to the inner wall of the limiting groove 72. Through the setting of the fixing component 7, the limiting pin 74 and the limiting card plate 75 are used in coordination to limit and fix the pressure ring 4, so that the pressure ring 4 can be stably engaged on the right side of the cuff base 3. At the same time, with the coordinated use of the limiting slider 73, the limiting groove 72 and the spring 76, the limiting pin 74 is elastically pushed, making the engagement of the limiting pin 74 and the limiting card plate 75 more stable.

[0024] Working principle: When the utility model is used, the user pushes the limit pin 74 downward to make the limit pin 74 disengage from the inner cavity of the limit card plate 75, and the spring 76 is compressed at the same time, and then the fixing plate 71 is loosened, and the compressed torsion spring 11 rebounds quickly to drive the pressure ring 4 to flip. At this time, the user sets the disposable cuff 6 in the inner cavity of the annular groove 5, flips the pressure ring 4 again, and pushes the limit pin 74, so that the limit pin 74 is re-engaged in the inner cavity of the limit card plate 75, and the disposable cuff 6 is between the cuff base 3 and the pressure ring 4;

[0025] Then, the patient's arm is inserted into the inner cavity from the front side of the detection arm tube 2, and the patient's palm squeezes the disposable cuff 6, causing the rolled disposable cuff 6 to gradually unfold. After the disposable cuff 6 is fully unfolded, the elastic rope 12 on the surface of the disposable cuff 6 slides out of the inner cavity of the reserved seam 13, so that the reserved seam 13 is sleeved on the user's arm. At this time, the patient's blood pressure can be tested by using the blood pressure detector 1 and the detection arm tube 2 in combination.

[0026] To sum up: the disposable cuff structure, through the coordinated use of the pressure ring 4, the annular groove 5 and the fixing assembly 7, installs the disposable cuff 6, and then extends the disposable cuff 6 on the arm through the patient's arm. Finally, with the coordinated use of the blood pressure detector 1 and the detection arm tube 2, the patient's blood pressure is tested, which can achieve the purpose of simple and convenient operation and prevention of instrument contamination, and solves the problem that the user's arm will directly contact the inner wall of the arm tube of the detector, and the inner wall of the arm tube will be contaminated to a certain extent after long-term use.
