[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 6 , the utility model provides a technical solution:

[0024] A mercury sphygmomanometer comprises a base box 1 with a suction cup at the bottom, a mountain-shaped hinge seat 2 is rotatably installed at the rear end of the inner cavity of the base box 1, a mounting groove 21 is provided in the mountain-shaped hinge seat 2, a hinge rod 3 is rotatably installed in the mounting groove 21 through a hinge shaft, a movable box 4 is fixedly installed on the upper surface of the hinge rod 3, a mercury column and a liquid storage container with a manual valve are fixedly installed in the movable box 4, a reset support device 5 and a positioning mechanism 6 are installed between the hinge rod 3 and the mountain-shaped hinge seat 2, the reset support device 5 is used to straighten the deflected hinge rod 3, thereby adjusting the position of the movable box 4 to make it vertical to the base box 1, thereby ensuring the normal operation of the mercury column, and the setting of the positioning mechanism 6 can further fix this vertical state when the mercury sphygmomanometer is in use, thereby ensuring the accuracy of measurement.

[0025] It should be noted that, combined with Figure 3 As shown, an arc groove 31 is formed between the left and right surfaces of the hinge rod 3;

[0026] The resetting supporting device 5 includes a semi-ring rod 51 and two arc springs 52. The two ends of the semi-ring rod 51 are respectively fixedly connected to the mountain-shaped hinge seat 2. The center position of the semi-ring rod 51 and the position of the hinge axis on the hinge rod 3 are on the same center axis, and the semi-ring rod 51 is slidably connected to the arc groove 31. The ends of the two arc springs 52 close to the hinge rod 3 are respectively fixedly connected to the outer surface of the hinge rod 3, and the ends of the two arc springs 52 away from the hinge rod 3 are respectively fixedly connected to the upper surface of the mountain-shaped hinge seat 2. The arc springs 52 are all sleeved on the outside of the semi-ring rod 51.

[0027] The semi-circular rod 51 can guide the hinged rod 3 during the flipping process, and the arc spring 52 supports the hinged rod 3 after the force is reversed. At the same time, after the force is released, the hinged rod 3 can be reset with the help of the extension force of the arc spring 52, and the movable box 4 can return to a vertical state with the base box 1.

[0028] like Figure 3 As shown, a slot is provided on the upper surface of the middle section of the mountain-shaped hinge seat 2, and the positioning mechanism 6 includes a positioning block 61 and an L-shaped iron piece 62, both of which are fixedly installed on the front surface of the hinge rod 3, and the L-shaped iron piece 62 is located above the positioning block 61, and an L-shaped pin rod 63 is inserted and installed through the positioning block 61, and the lower end of the L-shaped pin rod 63 is inserted and installed in the slot to position the hinge rod 3, and a magnet block A64 is embedded and installed on the upper surface of the L-shaped pin rod 63, and the upper surface of the magnet block A64 is flush with the upper surface of the L-shaped pin rod 63.

[0029] Before pre-exhausting the mercury column system, you need to manually lift up the L-shaped pin 63 to disengage it from the slot of the mountain-shaped hinge seat 2, and simultaneously keep the pin in a high position through the magnetic attraction of the magnet block A64 and the L-shaped iron piece 62 to ensure that the mechanical lock between the hinge rod 3 and the mountain-shaped hinge seat 2 is released. After the system is exhausted, you must manually press down the L-shaped pin 63 to re-engage it in the positioning slot, and ensure that the movable box 4 and the base box 1 are in a standard 90° vertical state through mechanical limiting. This operation can effectively avoid the reset deviation problem of the movable box 4 caused by fatigue failure of the arc spring 52, ensure the spatial positioning accuracy of the measurement reference surface, and thus ensure the accuracy and repeatability of the blood pressure measurement data.

[0030] In addition, in order to solve the problem that the cuff of the traditional mercury sphygmomanometer needs to be manually deflated after use, which is inconvenient to operate, Figure 1 As shown, a U-shaped pressure plate 7 is slidably installed in the movable box 4, two positioning partitions 11 are fixedly installed in the base box 1, a pressure cuff is placed between the two positioning partitions 11, an air pipe is connected between the pressure cuff and the liquid storage container, and an air bag with a valve is connected to the air inlet end of the pressure cuff;

[0031] When the mercury sphygmomanometer is in use, the U-shaped pressure plate 7 is above the mercury column and will not affect the observation of the mercury column reading. After the U-shaped pressure plate 7 slides down to the end, the movable box 4 is flipped toward the base box 1, so that the position of the U-shaped pressure plate 7 can be aligned between the two positioning partitions 11, and the cuff placed between the two positioning partitions 11 can be accurately pressurized and exhausted. This setting omits the need to use both hands to exhaust the cuff after use, making the cuff storage work more convenient.

[0032] Specifically, combined Figure 4 , Figure 5 and Figure 1 As shown, two L-shaped positioning frames 41 are fixedly installed in the movable box 4, and a slide groove 42 is formed between the L-shaped positioning frame 41 and the inner surface of the movable box 4. Two sliders 71 are fixedly installed on the rear surface of the U-shaped pressure plate 7 by screws. The sliders 71 are slidably installed in the slide groove 42. The movable box 4 is an iron box body, and the rear surfaces of the sliders 71 are embedded with magnet blocks B72 and fixedly installed.

[0033] When the mercury sphygmomanometer is used normally, the U-shaped pressing plate 7 can be absorbed and fixed on the top of the inner cavity of the movable box 4 by utilizing the cooperation between the U-shaped pressing plate 7 and the magnet block B72. This position will not affect the normal reading of the mercury column.

[0034] The L-shaped positioning frame 41 can limit the sliding distance of the U-shaped pressure plate 7. When it slides to the end of the slide groove 42, it is fixed on the inner surface of the movable box 4 by adsorbing it through the magnet block B72. This can ensure that after the U-shaped pressure plate 7 is flipped and fastened in the base box 1, the U-shaped pressure plate 7 is located between the two positioning partitions 11, ensuring that the cuff placed between the two positioning partitions 11 can be squeezed, thereby discharging the residual air in the cuff.

[0035] Principle of use: First, fix the device to the desktop through the vacuum suction cup of the base box 1, then deflect the movable box 4 to the left to pre-exhaust the mercury column system; open the manual valve to release the mercury in the liquid storage container to the standard working position, and then wrap the cuff correctly around the patient's upper arm and connect the pressure balloon. Press the balloon uniformly to inflate to the mercury column scale of 150mmHg (adult standard) or 180mmHg (special case) and stop pressurizing. Use a medical stethoscope to locate the brachial artery pulsation point at the same time. Slowly open the air valve, and when the Korotkoff sound is heard for the first time, record the corresponding scale of the mercury column as the systolic blood pressure value. After the detection is completed, the cuff is placed between the two positioning partitions 11 of the base box 1, and the U-shaped pressure plate 7 is lowered to the end of the slide groove 42. The position is fixed by cooperating with the magnet block B72. Subsequently, the movable box 4 is placed in the base box 1. After flipping it over for storage, the outer surface of the movable box 4 is attached to the upper surface of the positioning partition 11, and the U-shaped pressure plate 7 is embedded between the two positioning partitions 11. The cuff is squeezed by its own structure to exhaust the residual gas in the cuff. At this point, the storage is completed.
