[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-8 A blood pressure meter for physical examination provided by an embodiment of the present invention comprises a body 1, a through slot 101 for placing an arm is provided on the body 1, and the body 1 comprises a first half shell 11 and a second half shell 12; the second half shell 12 is rotatably connected to the first half shell 11 through a rotating shaft, and the second half shell 12 has a closed position in the rotation formation relative to the first half shell 11, and the through slot 101 of the body 1 is closed when the second half shell 12 is in the closed position, and a cuff 13 is movably arranged on the body 1; when the arm is placed on the first half shell 11, the second half shell 12 is rotated to the closed position through a linkage assembly 2, and when the second half shell 12 is in the closed position, the cuff 13 on the second half shell 12 contacts the arm, and specifically, the linkage assembly 2 comprises a rotating rod 21, a sliding sleeve 22, an L-shaped rod 23 and a first elastic member 24, the rotating rod 21 is coaxially fixedly connected with the rotating shaft, and a spiral groove 211 is provided on the rotating rod 21; the sliding sleeve 22 is horizontally slidably connected to the first half shell 11, and a ball rolling with the spiral groove 211 is provided on the sliding sleeve 22; the L-shaped rod 23 is vertically slidably connected to the first half shell 11, and a connecting rod 231 is hinged on the L-shaped rod 23, and the other end of the connecting rod 231 is hinged to the sliding sleeve 22; the first elastic member 24 is used to drive the L-shaped rod 23 to slide vertically upward, and the first elastic member includes a spring, one end of the spring is connected to the L-shaped rod 23, and the other end of the spring is connected to the first half shell 11. The body 1 is also provided with an air path module, a pressure measurement module, a signal processing module, a control module and a display module.

[0030] Working principle: before use, the arm needs to be placed on the first half shell 11. During the process of placing the arm on the first half shell 11, the arm will first abut against the L-shaped rod 23 to make the L-shaped rod 23 slide vertically downward, and at the same time, the L-shaped rod 23 will squeeze the spring to compress the spring. During the process of the L-shaped rod 23 sliding vertically downward, the L-shaped rod 23 will pull the sleeve 22 through the connecting rod 231 to make the sleeve 22 slide horizontally relative to the first half shell 11 (a guide rod is provided on the first half shell 11, and the sleeve 22 slides on the guide rod, thereby limiting the movement of the sleeve 22). The movement of the sleeve 22 will make the ball in the sleeve 22 cooperate with the spiral groove 211 on the rotating rod 21 to make the rotating rod 21 rotate, thereby rotating the rod The rotation of 21 drives the movement of the rotating shaft so that the second half shell 12 can rotate relative to the first half shell 11, until the second half shell 12 rotates to the closed position, the second half shell 12 stops rotating, and the arm will also fit with the cuff 13 on the first half shell 11. After the second half shell 12 rotates to the closed position, the cuff 13 on the second half shell 12 will also fit with the arm. At this time, the through slot 101 of the body 1 is closed and the arm passes through the through slot 101. The cuff 13 is inflated through the air circuit module to make the cuff 13 expand, and then the air circuit module inhales air to make the cuff 13 deflate. In this process, the pulse and other beats of the arm are analyzed through the pressure test module and the signal transmission module, and then the control module and the other modules are used to analyze the pulse of the arm. The display module obtains the result of blood pressure measurement. After the measurement is completed, due to the gap between the arm and the second half shell 12, the arm can move vertically upward. The L-shaped rod 23 of the arm moves vertically upward and is gradually reset by the elastic force of the spring, and then the second half shell 12 is moved away from the closed position through the linkage assembly 2. As the second half shell 12 moves away from the closed position, the arm can then be moved out, and it needs to be disinfected before the next user uses it. In this way, there is no need for medical staff to perform multiple steps of tying the cuff 13 on the user's arm. The user only needs to place the arm on the first half shell 11 to achieve the work of the cuff 13 fitting the arm before measurement, which greatly facilitates the user. In addition, compared with the The through slot 101 is an integrated body 1, and the user needs to align the arm with the through slot 101 before being able to insert the arm through the through slot 101. However, this device does not require the worker to align, and only needs to place the arm on the first half shell 11, which is more convenient during use. In addition, the device needs to measure the blood pressure of different people during use, and after measuring the blood pressure of each person, it is necessary to spray alcohol for disinfection. The integrated body is inconvenient for the worker to disinfect, and it is also inconvenient to observe whether the cleaning and disinfection are thorough. In addition, the device has higher flexibility. For some users with inflexible arms, it is easier to place the arm on the device than to pass the user's arm through the device. Therefore, the device has higher practical performance.

[0031] Compared with the prior art, the present invention provides a blood pressure monitor for physical examination. During the measurement process, the user first needs to place the arm on the first half shell 11. During the process of placing the user's arm on the first half shell 11, the arm triggers the linkage assembly 2 to drive the second half shell 12 to rotate to the closed position. When the second half shell 12 moves to the closed position, the through slot 101 of the body 1 is closed and the arm passes through the through slot 101. The arm passing through the through slot 101 will fit with the cuff 13 part on the first half shell 11 and the second half shell 12, and then the blood pressure of the arm is detected through the cuff 13. This reduces the steps of tying the cuff 13, making the measurement process more convenient and improving the measurement efficiency.

[0032] The cuff 13 is located at one end of the second half shell 12 and is provided with a cross bar 3. The first half shell 11 is provided with a guide groove 4, which includes a connected arc groove 41 and a cross groove 42. The first half shell 11 is provided with a plurality of elastic units 5 arranged in a staggered manner. Each elastic unit 5 includes an elastic telescopic rod 51, one end of the elastic telescopic rod 51 is fixedly connected to the body 1, and the other end is rotatably connected to a rotating rod 52; the cuff 13 is fitted with each rotating rod 52. Specifically, the elastic telescopic rod 51 includes a sleeve rod 511 and an inner sleeve rod 512. The rod 512 and the sleeve rod 511 are fixedly connected in the first half shell 11, the inner rod 512 is slidably connected to the sleeve rod 511, the rotating rod 52 is rotatably connected to the inner rod 512, and a second elastic member is arranged between the sleeve rod 511 and the inner rod 512. When the second half shell 12 moves to the closed position, the medical staff or the user pulls the cross bar 3 by themselves, so that the cross bar 3 enters the guide groove until the cross bar 3 enters the transverse groove 42 and stops pulling. In this process, taking one of the elastic units 5 as an example, the cuff 13 abuts against the rotating rod The rotating rod 52 drives the inner rod 512 of the elastic telescopic rod 51 to slide relative to the sleeve rod 511, and in this process, the inner rod 512 pulls the second elastic member. When the rotating rod 52 of each elastic unit 5 is in the vertical plane (the horizontal groove 42 in the guide groove 4 makes the cross bar 3 unable to move vertically, so that the cross bar 3 pulls the cuff 13, and the cuff 13 abuts against each rotating rod 52 so that the rotating rod 52 is in the same vertical plane and maintains this state), the cuff 13 is also in a straight state, and the rotating rod 52 is outside the body 1. The cuff 13 is extended so that the cuff 13 has a larger area in contact with the arm, thereby making the measured data more accurate. In addition, when use is finished, it is only necessary to separate the cross bar 3 from the cross groove 42, and the inner rod 512 is pulled by the second elastic member to approach the sleeve rod 511, and then the inner rod 512 drives the rotating rod 52 to move, and the rotating rod 52 abuts against the cuff 13, thereby restoring the cuff 13 to a wavy shape. In addition, the rotating rod 52 is rotatably connected to the inner rod 512 to reduce the friction generated when the cuff 13 abuts against the rotating rod 52.

[0033] Among them, a straight groove 212 connected to the spiral groove 211 is also provided on the rotating rod 21. When the arm is always against one end of the L-shaped rod 23, since the arm is on the cuff 13 of the first half shell 11, and the cuff 13 has two forms of inflation and deflation during the measurement process, the cuff 13 will drive the arm to move in a small range, so that the arm will drive the L-shaped rod 23 to move in a small range. During this process, the L-shaped rod 23 drives the connecting rod 231 to move the sliding sleeve 22, and the ball in the sliding sleeve 22 moves in the straight groove 212, which will not affect the state of the second half shell 12 being in a closed position.

[0034] Among them, an arc-shaped slide rail 121 is opened on the second half shell 12, and a slider 122 is slidably connected to the slide rail 121. The slider 122 is fixedly connected to the cuff 13. The cuff 13 can be fitted on the second half shell 12 by sliding the slider 122 on the slide rail 121 and the slider 122 is fixedly connected to the cuff 13.

[0035] The second half shell 12 is provided with a buckle 6 that cooperates with the cross bar 3 to prevent the cross bar 3 from falling off the second half shell 12 .

[0036] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
