Description

Technical Field

[0001] This utility model relates to the field of medical cardiac pressure device technology, specifically to an auxiliary structure for a pressure gauge in a medical cardiac pressure device. Background Technology

[0002] Medical blood pressure monitoring devices generally refer to equipment used to measure blood pressure, including traditional mercury sphygmomanometers, gimbal sphygmomanometers, and modern electronic sphygmomanometers. Pressure gauge auxiliary structures refer to a series of components or designs that help these devices measure blood pressure more accurately or make operation easier.

[0003] Existing auxiliary structures can be referenced from Chinese Utility Model Patent Publication No. CN218294301U, which discloses a protective structure for a blood pressure monitor. The structure includes a blood pressure monitor, with protective plates fixedly connected to each of the four corners of the monitor's surface. A support rod is fixedly connected to the surface of the monitor. A support groove is formed on the inner side of the protective plate, slidably connected to the support rod. A movable groove is formed inside the support groove, and a support block is disposed inside the movable groove. The support block is fixedly connected to the surface of the support rod, and a spring is fixedly connected to the outer side of the support block. The outer side of the spring is fixedly connected to the inside of the movable groove. This utility model, through the coordinated use of the blood pressure monitor, protective plates, support rod, support groove, movable groove, support block, and spring, solves the problem that the protective effect of existing blood pressure monitors still needs improvement. Furthermore, if the blood pressure monitor is dropped or vibrated during use, internal parts may be damaged, posing a safety hazard and inconvenience to the user.

[0004] When the aforementioned device needs to protect the blood pressure monitor, the user can use the protective plate to protect the four corners of the monitor. When the blood pressure monitor is impacted, the protective plate can absorb and cushion the impact force. Simultaneously, the shock-absorbing pads absorb the impact force, and the support rods and blocks can limit the protective plate to prevent it from detaching from the monitor. The limiting blocks also protect the front of the monitor, thus achieving good protection. However, the above device only protects blood pressure monitors of a specific size. When changing to different sizes of blood pressure monitors, different protective structures need to be replaced. For other sizes or models of blood pressure monitors, it may be necessary to redesign or adjust components such as the protective plate and support rods, reducing its practicality and convenience. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary structure for a pressure gauge in a medical cardiac pressure device, which has the advantages of flexible adjustment and good protection. It can not only provide physical protection, but also flexibly adjust the position of the arc-shaped protective shell as needed to adapt to blood pressure monitors of different sizes or shapes, or better protect the equipment during transportation, storage and other conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary structure for a medical cardiac pressure device, comprising a sphygmomanometer and a support shell disposed at its bottom, wherein the top of the support shell is provided with four guide grooves arranged in a circumferential array, and the sphygmomanometer is provided with arc-shaped protective shells at each of its four corners. Four arc-shaped protective shells are arranged in a circumferential array on the top of the support shell. Each of the four arc-shaped protective shells has a fixed rod fixedly connected to its bottom center. The bottom of each of the four fixed rods extends into the interior of the support shell and is slidably connected to the inner wall of the guide groove. The moving path of the four fixed rods is from the four corners of the support shell to its center.

[0007] As a preferred auxiliary structure for a pressure gauge in a medical cardiac pressure device according to this utility model, each of the four arc-shaped protective shells has an arc-shaped rubber pad on its inner wall, the inner wall of each of the four arc-shaped rubber pads is fitted to the four corners of the blood pressure monitor, and each of the four arc-shaped rubber pads has an arc-shaped rubber ring inside.

[0008] As a preferred auxiliary structure of the pressure gauge of the medical cardiac pressure device of this utility model, an inflation tube is fixedly connected to one side of each of the four arc-shaped rubber rings. The four inflation tubes pass through the outside of the four arc-shaped protective shells and are fixedly connected thereto. A sealing element is movably connected to the end of each of the four inflation tubes away from the arc-shaped rubber rings.

[0009] As a preferred auxiliary structure of the pressure gauge for a medical cardiac pressure device of this utility model, the four arc-shaped protective shells are divided into left and right groups. Multiple elastic telescopic airbags are fixedly connected between the front and rear two arc-shaped rubber rings in each group. The front and rear ends of the multiple elastic telescopic airbags are fixedly connected to the front and rear two arc-shaped rubber rings on the side close to each other, and the multiple elastic telescopic airbags are slidably connected to the front and rear two arc-shaped protective shells.

[0010] As a preferred auxiliary structure of the pressure gauge for a medical cardiac pressure device according to this utility model, a bevel gear ring is rotatably connected to the bottom center of the inner wall of the support shell, a power bevel gear is meshed with the front side of the top of the bevel gear, a rotating rod is fixedly connected to the inner wall of the power bevel gear, and the end of the rotating rod away from the power bevel gear extends to the front side of the outer side of the support shell and is rotatably connected to it.

[0011] As a preferred auxiliary structure of the pressure gauge for a medical cardiac pressure device according to this utility model, the rotating rod extends to one end of the front side of the support shell and is fixedly connected to a knob. The top of the bevel gear ring is circumferentially arrayed and meshed with four driven bevel gears. The four driven bevel gears are arranged in a circumferential array inside the support shell and are rotatably connected to it.

[0012] As a preferred auxiliary structure of the pressure gauge for a medical cardiac pressure device according to this utility model, each of the four driven bevel gears has a threaded rod fixedly connected to its inner wall. The end of each of the four threaded rods away from the four driven bevel gears is rotatably connected to the four corners of the inner wall of the support shell. Each of the four threaded rods has a threaded sleeve threadedly connected to its surface, and each of the four threaded sleeves has a fixed rod fixedly connected to its top.

[0013] As a preferred auxiliary structure of the pressure gauge for a medical cardiac pressure device according to this utility model, four guide rods are arranged in a circular array at the four corners inside the support shell. The four guide rods are fixedly connected at one end close to each other to the bottom of the inner wall of the support shell, and at the other end far from each other to the four corners of the inner wall of the support shell. The four threaded sleeves are slidably connected to the four guide rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features four arc-shaped protective shells located at the four corners of the top of the support shell. These shells are connected to threaded sleeves via fixing rods, and the threaded sleeves are positioned along guide rods. In this configuration, the blood pressure monitor is surrounded by the arc-shaped protective shells and tightly fitted by arc-shaped rubber rings, providing basic protection. If further adjustment of the fit of the arc-shaped rubber rings to the blood pressure monitor is required, air can be injected into the arc-shaped rubber rings through the inflation tube and sealed with a sealant to maintain internal pressure and ensure optimal fit. In certain situations, such as impacts or vibrations, the elastic telescopic air bladder can absorb energy, reducing direct impact on the blood pressure monitor while allowing for some deformation to adapt to different usage environments.

[0015] 2. When adjusting the position or clamping force of the arc-shaped protective shell, the user rotates the external knob, which is fixedly connected to the rotating rod. The rotating rod extends into the support shell and drives the power bevel gear to rotate. The power bevel gear meshes with the bevel gear ring, so its rotation drives the bevel gear ring to rotate as well. Four driven bevel gears are arranged in a circular array on the top of the bevel gear ring, and the driven bevel gears rotate synchronously with the rotation of the bevel gear ring. A threaded rod is fixedly connected to the inner wall of each driven bevel gear. When the driven bevel gear rotates, the threaded rod also rotates. Since the threaded rod surface is threaded with a threaded sleeve, and the threaded sleeve can only slide along the guide rod, the rotation of the threaded rod causes the threaded sleeve to move along the surface of the threaded rod. The movement of the threaded sleeve directly drives the fixed rod to move along the guide groove from the periphery of the positioning shell to its center, thereby changing the position of the arc-shaped protective shell relative to the blood pressure monitor. If a tighter clamping of the blood pressure monitor is required or for transportation protection, the arc-shaped protective shell can be moved closer to the center by rotating the knob; conversely, when loosening, it expands outward.

Detailed Implementation

[0018] Please see Figures 1-4 An auxiliary structure for a medical cardiac pressure device includes a sphygmomanometer 1 and a support shell 2 located at its bottom. The top of the support shell 2 has four guide grooves 201 arranged in a circumferential array. The sphygmomanometer 1 has arc-shaped protective shells 3 at each of its four corners. Furthermore, four arc-shaped protective shells 3 are arranged in a circular array on the top of the support shell 2. Each of the four arc-shaped protective shells 3 has a fixed rod 9 fixedly connected to its bottom center. The bottom of the four fixed rods 9 extends into the interior of the support shell 2 and slides between them and the inner wall of the guide groove 201. The moving path of the four fixed rods 9 is from the four corners of the support shell 2 to its center.

[0019] The blood pressure monitor 1 is the core part of the whole device and is responsible for measuring blood pressure. The support shell 2 is located at the bottom of the blood pressure monitor 1, providing support and protection for the whole device. Four guide grooves 201 are arranged in a circular array on the top. The guide grooves 201 are used to guide the movement of the fixing rod 9, thereby adjusting the position of the arc-shaped protective shell 3.

[0020] There are four arc-shaped protective shells 3 arranged in a circular array around the blood pressure monitor 1. Their main function is to provide physical protection for the blood pressure monitor 1, preventing damage caused by impact or drops. Each arc-shaped protective shell 3 has a fixing rod 9 connected to its bottom center. The fixing rod 9 extends into the interior of the support shell 2 and slides between itself and the inner wall of the guide groove 201. Through this design, the fixing rod 9 can move within the guide groove 201, allowing the arc-shaped protective shell 3 to move closer to or away from the center of the support shell 2.

[0021] Furthermore, each of the four arc-shaped protective shells 3 has an arc-shaped rubber pad 4 on its inner wall, and each of the four arc-shaped rubber pads 4 has an arc-shaped rubber ring 5 on its inner wall. The inner walls of the four arc-shaped rubber rings 5 ​​are fitted to the four corners of the blood pressure monitor 1.

[0022] An arc-shaped rubber pad 4 is installed on the inner wall of each arc-shaped protective shell 3. The function of the arc-shaped rubber pad 4 is to increase the cushioning effect, reduce the impact of external impacts on the blood pressure monitor 1, and also prevent direct friction damage to the outer shell of the blood pressure monitor 1. An arc-shaped rubber ring 5 is installed on the inner wall of each arc-shaped rubber pad 4. The arc-shaped rubber ring 5 is designed to fit more tightly at the four corners of the blood pressure monitor 1, providing a more stable clamping force and ensuring that the blood pressure monitor 1 will not easily slip or be displaced by accidental collisions during use.

[0023] Furthermore, an inflation tube 6 is fixedly connected to one side of each of the four arc-shaped rubber rings 5. The four inflation tubes 6 pass through the outside of the four arc-shaped protective shells 3 and are fixedly connected to them. A sealing element 7 is movably connected to the end of each of the four inflation tubes 6 away from the arc-shaped rubber rings 5.

[0024] Each of the four curved rubber rings 5 ​​protecting the four corners of the blood pressure monitor 1 is equipped with an inflation tube 6. This is to adjust the internal pressure of the curved rubber ring 5 as needed to accommodate blood pressure monitors 1 of different sizes or shapes, ensuring optimal fit and stability. The seal 7 prevents gas leakage and ensures that the inflation tube 6 can effectively maintain the pressure inside the curved rubber ring 5. Furthermore, the movable connection means that users can easily open or close the seal 7 as needed, facilitating pressure adjustment or maintenance and cleaning of the curved rubber ring 5.

[0025] Furthermore, the four arc-shaped protective shells 3 are divided into left and right groups. Each group has multiple elastic telescopic airbags 8 fixedly connected between the front and rear two arc-shaped rubber rings 5. The front and rear ends of the multiple elastic telescopic airbags 8 are fixedly connected to the front and rear two arc-shaped rubber rings 5 ​​on the side close to each other, and the multiple elastic telescopic airbags 8 are slidably connected to the front and rear two arc-shaped protective shells 3.

[0026] Multiple elastic telescopic airbags 8 are arranged between the two front and rear arc-shaped rubber rings 5 ​​in each group. The function of the elastic telescopic airbags 8 is to provide additional cushioning protection and allow a certain degree of deformation to adapt to different sizes of blood pressure monitors 1 or changes in external pressure. The multiple elastic telescopic airbags 8 are slidably connected to the two front and rear arc-shaped protective shells 3, indicating that the elastic telescopic airbags 8 can not only freely expand and contract during inflation or deflation, but also slide relative to the arc-shaped protective shells 3. This design increases the flexibility of the entire system, ensuring effective protection of the blood pressure monitor 1 even under different usage conditions.

[0027] Furthermore, a bevel gear ring 10 is rotatably connected to the bottom center of the inner wall of the support shell 2, and a power bevel gear 11 is meshed with the top front side of the bevel gear ring 10. A rotating rod 12 is fixedly connected to the inner wall of the power bevel gear 11, and the end of the rotating rod 12 away from the power bevel gear 11 extends to the front side of the outer side of the support shell 2 and is rotatably connected to it.

[0028] As one of the core components of the entire mechanical transmission system, the bevel gear ring 10 can rotate around its central axis. A power bevel gear 11 meshes with the front top of the bevel gear ring 10. When the power bevel gear 11 rotates, it drives the bevel gear ring 10 to rotate as well. The power bevel gear 11 is fixed to a rotating rod 12, which extends from inside the support shell 2 to its outer front side and is rotatably connected to the support shell 2. Thus, by operating the rotating rod 12, the rotation of the power bevel gear 11 can be controlled.

[0029] Furthermore, the rotating rod 12 extends to the front side of the support shell 2 and is fixedly connected to a knob 13. The top of the bevel ring 10 is connected to four driven bevel gears 14 in a circumferential array. The four driven bevel gears 14 are arranged in a circumferential array inside the support shell 2 and are rotatably connected to it.

[0030] A knob 13 is fixedly connected to one end of the rotating rod 12 extending to the front side of the support shell 2. The user can drive the entire mechanical system by rotating this knob 13, that is, to rotate the bevel ring 10 through the rotating rod 12 and the power bevel gear 11. The top of the bevel ring 10 is also connected to four driven bevel gears 14 in a circumferential array. The driven bevel gears 14 are evenly distributed inside the support shell 2 and are rotatably connected to the support shell 2. When the bevel ring 10 rotates, it will drive these four driven bevel gears 14 to rotate synchronously.

[0031] Furthermore, each of the four driven bevel gears 14 has a threaded rod 15 fixedly connected to its inner wall. The end of each threaded rod 15 away from the four driven bevel gears 14 is rotatably connected to the four corners of the inner wall of the support shell 2. Each of the four threaded rods 15 has a threaded sleeve 16 threadedly connected to its surface. Each of the four threaded sleeves 16 has a fixed rod 9 fixedly connected to its top.

[0032] Each driven bevel gear 14 has a threaded rod 15 fixedly connected to its inner wall. When the driven bevel gear 14 rotates, the threaded rod 15 also rotates. The ends of the four threaded rods 15 away from the driven bevel gear 14 are rotatably connected to the four corners of the inner wall of the support shell 2. This ensures that the threaded rods 15 can rotate freely while maintaining their position. Each threaded rod 15 has a threaded sleeve 16 threadedly connected to its surface, and a fixing rod 9 is fixedly connected to the top of each threaded sleeve 16. When the threaded rod 15 rotates, the threaded sleeve 16 moves along the threaded rod 15 due to the action of the thread, thereby driving the fixing rod 9 to move from the periphery of the support shell 2 towards its center along the guide groove 201.

[0033] Furthermore, four guide rods 17 are arranged in a circumferential array at the four corners inside the support shell 2. The four guide rods 17 are fixedly connected at one end close to each other to the bottom of the inner wall of the support shell 2, and at the other end far from each other to the four corners of the inner wall of the support shell 2. The four threaded sleeves 16 are slidably connected to the four guide rods 17.

[0034] The guide rods 17 are designed to guide the movement path of the threaded sleeves 16, ensuring that they can move smoothly and accurately along the predetermined direction. The four threaded sleeves 16 are slidably connected to the four guide rods 17, which means that the threaded sleeves 16 can slide smoothly on the guide rods 17 while being constrained by the guide rods 17 to prevent deviation from the track or unnecessary tilting.

[0035] When not in operation, the four arc-shaped protective shells 3 are located at the four corners of the top of the support shell 2. They are connected to the threaded sleeves 16 by the fixing rods 9. The threaded sleeves 16 are positioned along the guide rods 17. At this time, the blood pressure monitor 1 is surrounded by the arc-shaped protective shells 3 and tightly fitted by the arc-shaped rubber rings 5, providing basic protection.

[0036] When it is necessary to adjust the position or clamping force of the arc-shaped protective shell 3, the user rotates the external knob 13. The knob 13 is fixedly connected to the rotating rod 12, which extends into the support shell 2 and drives the power bevel gear 11 to rotate. The power bevel gear 11 meshes with the bevel gear ring 10, so its rotation will drive the bevel gear ring 10 to rotate together. The top circumferential array of the bevel gear ring 10 has four driven bevel gears 14, which rotate synchronously with the rotation of the bevel gear ring 10.

[0037] Each driven bevel gear 14 has a threaded rod 15 fixedly connected to its inner wall. When the driven bevel gear 14 rotates, the threaded rod 15 also rotates. Since the threaded rod 15 has a threaded sleeve 16 threadedly connected to its surface, and the threaded sleeve 16 can only slide along the guide rod 17, the rotation of the threaded rod 15 will cause the threaded sleeve 16 to move along the surface of the threaded rod 15.

[0038] The movement of the threaded sleeve 16 directly drives the fixed rod 9, which is fixed to it, to move along the guide groove 201 from the periphery of the support shell 2 toward its center, thereby changing the position of the arc-shaped protective shell 3 relative to the blood pressure monitor 1. If it is necessary to clamp the blood pressure monitor 1 more tightly or to protect it during transportation, the arc-shaped protective shell 3 can be moved closer to the center by rotating the knob 13; conversely, when it is loosened, it expands outward.

[0039] If further adjustment of the fit between the curved rubber ring 5 and the blood pressure monitor 1 is required, air can be injected into the curved rubber ring 5 through the inflation tube 6 and sealed with the seal 7 to ensure internal pressure and optimal fit. In certain situations, such as impacts or vibrations, the elastic telescopic air bladder 8 can absorb energy, reducing the direct impact on the blood pressure monitor 1, while allowing a certain degree of deformation to adapt to different usage environments.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
