Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to a tunnel-type blood pressure monitor. Background Technology

[0002] Tunnel blood pressure monitors, also known as arm cuff blood pressure monitors, are more automated than regular electronic blood pressure monitors because they do not require manual wrapping of the cuff.

[0003] Currently, common tunnel-type blood pressure monitors on the market typically include a main unit, an arm tube assembly connected to the main unit, and a hand rest connected to the main unit. The arm tube assembly includes an arm tube, an air bladder inside the arm tube, a retainer inside the arm tube and outside the air bladder, and a drive assembly located in the arm tube. The drive assembly can drive one end of the retainer to change the diameter of the retainer, thereby causing the air bladder to press against the user's arm under the action of the retainer. However, although existing arm tube assemblies can achieve automatic air bladder pressing against the user's arm, their complex structure results in a large arm tube assembly size and high assembly difficulty, as well as a high failure rate. This, in turn, leads to a large size, high manufacturing cost, and high failure rate in tunnel-type blood pressure monitors. Utility Model Content

[0004] This application provides a tunnel-type blood pressure monitor to reduce the size of the tunnel-type blood pressure monitor, reduce the manufacturing cost of the tunnel-type blood pressure monitor, and reduce the failure rate of the tunnel-type blood pressure monitor.

[0005] The technical solution adopted in this application is as follows: A tunnel-type blood pressure monitor includes: A host computer having a first side and a second side opposite to the first side; An arm cylinder assembly is hinged to the first side. The arm cylinder assembly includes a housing with a central hole, an outer airbag located in the central hole, an annular support located inside the outer airbag, an inner airbag located inside the annular support, and a connector fixedly connected to the outer airbag and the inner airbag. The outer airbag is fixedly connected to the hole wall of the central hole, and the annular support can be rolled up and down under the expansion and contraction of the outer airbag. A handrest, which is hinged to the second side.

[0006] By adopting the above technical solution, when using the tunnel-type blood pressure timer of this application, the user first inserts their arm into the central hole, with their arm positioned inside the inner air bladder. The user's forearm is placed on the hand rest, so that the inner air bladder is located at the user's upper arm. The hand rest supports the user's forearm. Then, the main unit is activated, supplying air to the outer air bladder, causing it to inflate. The annular support deforms and retracts under the inflating effect of the outer air bladder, gradually reducing its diameter until the inner air bladder is pressed against the user's upper arm. Then, the main unit stops supplying air to the outer air bladder and supplies air to the inner air bladder, causing it to gradually inflate and apply pressure to the user's upper arm. Finally, the main unit deflates the inner air bladder and measures the user's blood pressure.

[0007] After the blood pressure measurement is completed, the main unit deflates the external airbag, which gradually reduces the volume of the external airbag and reduces the pressure exerted by the external airbag on the ring support. At this time, the ring support gradually recovers its deformation under its own elastic force, thereby gradually increasing the diameter of the ring support. Then the user can pull the arm out of the central hole.

[0008] Because the tunnel-type blood pressure monitor in this application achieves the goal of pressing the inner airbag against the user's arm by expanding the outer airbag, compared with the prior art solution of pressing the airbag against the user's arm by driving one end of the ring bracket through a drive component, it simplifies the structural design of the arm cylinder assembly, thereby reducing the volume of the arm cylinder assembly, reducing the assembly difficulty of the arm cylinder assembly, and reducing the failure rate of the arm cylinder assembly. This, in turn, reduces the volume of the tunnel-type blood pressure monitor, reduces the manufacturing cost of the tunnel-type blood pressure monitor, and reduces the failure rate of the tunnel-type blood pressure monitor, thereby increasing the service life of the tunnel-type blood pressure monitor and improving the user experience.

[0009] Meanwhile, since the outer airbag is fixedly connected to the wall of the central hole, the annular support is located between the outer and inner airbags, and the connector is fixedly connected to the outer and inner airbags, the stability of the outer airbag and the annular support is increased on the one hand, and the stability of the annular support is increased on the other hand. Furthermore, it can also ensure the driving effect of the annular support on the outer airbag when the outer airbag inflates and the driving effect of the annular support on the outer airbag when the volume of the outer airbag shrinks. At the same time, it can also increase the stability of the inner airbag, so that when the diameter of the annular support changes, the inner airbag can move with the annular support.

[0010] Furthermore, since the arm tube assembly is hinged to the first side of the main unit and the hand rest is hinged to the second side of the main unit, the arm tube assembly and hand rest can be flipped upwards after the tunnel blood pressure monitor has been used to store the arm tube assembly and hand rest, thereby reducing the space occupied by the tunnel blood pressure monitor when it is stored, thus facilitating the storage and transportation of the tunnel blood pressure monitor.

[0011] Optionally, the annular bracket has a first end fixedly connected to the connector and a second end opposite to the first end. The connector is fixedly connected to the outer airbag and the inner airbag, and a passage is formed between the inner airbag and the connector for the second end to extend into.

[0012] By adopting the above technical solution, since the first end of the annular support is fixedly connected to the connector, and the connector is fixedly connected to the outer air bladder and the inner air bladder, the fixed connection between the annular support and the outer air bladder is achieved on the one hand, and the fixed connection between the inner air bladder and the annular support is achieved on the other hand, thereby increasing the connection stability between the inner air bladder and the annular support. Furthermore, since a through-channel is formed between the inner air bladder and the connector for the second end to extend into, the second end can avoid contact with the inner side of the inner air bladder, thereby increasing the accuracy of blood pressure measurement by the tunnel-type sphygmomanometer. On the other hand, the through-channel can guide the second end, thereby increasing the stability of the second end during movement. At the same time, the through-channel can limit the second end, preventing it from protruding from the opening of the central hole, thereby increasing the stability of the annular support. Moreover, compared with the solution where the second end extends between the outer air bladder and the first end, the resistance during the movement of the second end can be reduced, thereby ensuring the smoothness of the movement of the second end and improving the measurement efficiency of the tunnel-type sphygmomanometer.

[0013] Optionally, the connector includes an inner connecting layer and an outer connecting layer, with a receiving channel formed between the inner connecting layer and the outer connecting layer, the first end extending into the receiving channel, and the external airbag fixedly connected to the outer connecting layer.

[0014] By adopting the above technical solution, since a receiving channel is formed between the inner connecting layer and the outer connecting layer, the first end extends into the receiving channel, thereby increasing the connection area between the first end and the connector, so as to increase the connection stability between the ring bracket and the connector.

[0015] Optionally, the arm sleeve assembly further includes an elastic sleeve located inside the inner airbag, with both ends of the sleeve fixedly connected to the housing.

[0016] By adopting the above technical solution, the cuff is elastic, located inside the inner air bladder, and both ends of the cuff are fixedly connected to the shell. This allows the cuff to limit the position of the annular support and the inner air bladder, preventing them from protruding from the central hole and increasing their stability. Furthermore, when the outer air bladder deflates, the elasticity of the cuff accelerates the recovery of the annular support's deformation, allowing the inner air bladder to separate from the user's arm in a shorter time, thus improving the measurement efficiency of the tunnel-type blood pressure monitor. Additionally, the cuff allows the inner air bladder to be pressed firmly against the user's arm, improving the user's comfort during blood pressure measurement.

[0017] Optionally, the housing has a hinge arm with a hinge shaft passing through the main unit, and the hinge shaft is fitted with a damping body located between the hinge arm and the main unit.

[0018] By adopting the above technical solution, since the housing has a hinge arm and the hinge arm has a hinge shaft passing through the main unit, the arm cylinder assembly and the main unit are hinged. Since the hinge shaft is fitted with a damping body located between the hinge arm and the main unit, the damping body can be used to generate a damping effect when the arm cylinder assembly and the main unit rotate relative to each other, thereby improving the product quality of the tunnel blood pressure monitor and further improving the user experience.

[0019] Optionally, the main unit includes a housing and a first inflation assembly. The top end face of the housing is inclined downward along the direction from the second side to the first side. The housing has an installation position located near the second side. The first inflation assembly is used to inflate and deflate the external airbag, and the first inflation assembly includes at least two first air pumps installed at the installation position.

[0020] By adopting the above technical solution, since the top end face of the housing is inclined downwards along the direction from the second side to the first side, the height of the second side of the housing is greater than the height of the first side, making the space inside the housing near the second side larger than the space inside the housing near the first side. Furthermore, since the housing has a mounting position near the second side, and the first inflation component includes a first air pump installed at the mounting position, this allows for efficient use of the space inside the housing near the second side, facilitating the installation of the first air pump. It also allows the first air pump to be closer to the second side, increasing the weight on the second side, thereby maximizing the weight distribution of the tunnel sphygmomanometer in its stored state. The weight distribution is even to prevent the tunnel blood pressure monitor from slipping out of the user's hand when it is stored, thus improving the user experience. Furthermore, since the first inflation component includes at least two first air pumps, it improves the inflation efficiency of the outer air bladder, allowing it to inflate quickly and press the inner air bladder firmly against the user's arm in a shorter time, thereby improving the measurement efficiency of the tunnel blood pressure monitor. Additionally, it ensures that the tunnel blood pressure monitor can continue to operate even if one of the first air pumps malfunctions, extending its lifespan.

[0021] Optionally, the first inflation assembly further includes a first connector, a first pressure sensor, and at least two first deflation valves. The first connector has a first communication port connected to the air outlet of the first air pump, a first pressure port connected to the first pressure sensor, a first deflation port connected to the first deflation valve, and a first air supply port connected to the external airbag. And / or, the host unit further includes a second inflation assembly for inflating and deflating the internal airbag, the second inflation assembly including a second air pump mounted at the mounting position.

[0022] By adopting the above technical solution, since there are at least two first vent valves, the venting efficiency of the outer airbag can be improved, allowing the outer airbag to expel the air inside in a shorter time, thereby shortening the user's waiting time and further improving the measurement efficiency of the tunnel blood pressure monitor and the user experience. Furthermore, since the first connector has a first connection port connected to the air outlet of the first air pump, a first pressure port connected to the first pressure sensor, a first vent port connected to the first vent valve, and a first air supply port connected to the outer airbag, the two first air pumps can be connected to the pressure sensor and the outer airbag through the same component, reducing the number of components required for the tunnel blood pressure monitor, thereby further improving the assembly efficiency of the tunnel blood pressure monitor and further reducing the manufacturing cost of the tunnel blood pressure monitor.

[0023] Because the second air pump is installed in the mounting position, the second air pump and the first air pump are integrated in the same position in the housing, so that the internal components of the housing are more regularly distributed, thereby facilitating the maintenance of the tunnel blood pressure monitor. At the same time, it can further make the weight distribution of the tunnel blood pressure monitor in the storage state more even.

[0024] Optionally, the housing has an internal accommodating cavity and a mounting cavity. The accommodating cavity contains a circuit board and a battery electrically connected to the circuit board. The mounting position is located in the mounting cavity. The arm cylinder assembly and the hand rest are located on opposite sides of the mounting cavity. The housing is provided with a start / stop button electrically connected to the circuit board and a charging interface electrically connected to the circuit board. The start / stop button is located at the end of the mounting cavity away from the accommodating cavity, and the charging interface is located at the end of the accommodating cavity away from the mounting cavity.

[0025] By adopting the above technical solution, since the mounting position is located in the mounting cavity, and the hand rest and arm cylinder assembly are located on opposite sides of the mounting cavity, the distance between the first and second inflation components and the arm cylinder assembly can be reduced. This shortens the length of the pipes connecting the first inflation component and the outer air bladder, as well as the length of the pipes connecting the second inflation component and the inner air bladder, further reducing the manufacturing cost of the tunnel-type blood pressure monitor. Furthermore, since the start / stop button is located at the end of the mounting cavity away from the receiving cavity, and the charging interface is located at the end of the receiving cavity away from the mounting cavity, the charging interface and the start / stop button can avoid each other, making it easier for the user to press the start / stop button and charge the battery. On the other hand, the circumferential space of the casing can be rationally utilized to facilitate the assembly of the charging interface and the start / stop button, thereby further improving the assembly efficiency of the tunnel-type blood pressure monitor and further reducing its manufacturing cost.

[0026] Optionally, the accommodating cavity is provided with an emergency stop module electrically connected to the circuit board. The emergency stop module is located near the second side and has an emergency button that extends out of the housing.

[0027] By adopting the above technical solution, since the accommodating cavity is equipped with an emergency stop module electrically connected to the circuit board, and the emergency stop module has an emergency button that extends out of the housing, the user can press the emergency button to stop the tunnel blood pressure monitor in an emergency, thereby further improving the user experience. Furthermore, since the emergency stop module is located close to the second side, the space near the second side of the accommodating cavity can be used reasonably to increase the structural compactness of the main unit, thereby achieving the effect of facilitating the miniaturization design of the tunnel blood pressure monitor.

[0028] Optionally, the handrest is provided with a handhold for the user to hold, the handhold being located at the end of the handrest away from the host.

[0029] By adopting the above technical solution, since the handrest is equipped with a handhold for the user, the user can hold the handhold when moving the tunnel blood pressure monitor, thus making it easier to move and improving the user experience. Furthermore, since the handhold is located at the end of the handrest away from the main unit, it can avoid contact with the main unit, making it easier for the user to grip and thus further improving the user experience.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The tunnel-type blood pressure monitor of this application includes a main unit, an arm cylinder assembly, and a hand rest. The main unit has a first side and a second side opposite to the first side. The arm cylinder assembly is hinged to the first side and includes a housing with a central hole, an outer air bladder located in the central hole, an annular support located inside the outer air bladder, an inner air bladder located inside the annular support, and a connector fixedly connected to the outer air bladder and the inner air bladder. The outer air bladder is fixedly connected to the wall of the central hole, and the annular support can be rolled up and down under the expansion and contraction of the outer air bladder. The hand rest is hinged to the second side. Compared with the prior art solution of driving one end of the annular support through a drive assembly to achieve the air bladder pressing against the user's arm, the structural design of the arm cylinder assembly is simplified, thereby reducing the volume of the arm cylinder assembly, reducing the assembly difficulty of the arm cylinder assembly, and reducing the failure rate of the arm cylinder assembly. This, in turn, reduces the volume of the tunnel-type blood pressure monitor, reduces the manufacturing cost of the tunnel-type blood pressure monitor, and reduces the failure rate of the tunnel-type blood pressure monitor, thereby improving the service life of the tunnel-type blood pressure monitor and achieving the effect of improving the user experience.

[0031] 2. The annular support in this application has a first end fixedly connected to the connector and a second end opposite to the first end. The connector is fixedly connected to the outer air bladder and the inner air bladder, thereby achieving a fixed connection between the annular support and the outer air bladder, and a fixed connection between the inner air bladder and the annular support, increasing the connection stability between the inner air bladder and the annular support. A through-channel is formed between the inner air bladder and the connector, allowing the second end to pass through, thus enabling the second end to avoid contact with the inner side of the inner air bladder, increasing the accuracy of blood pressure measurement by the tunnel-type sphygmomanometer. Furthermore, the through-channel guides the second end, increasing its stability during movement. It also limits the second end to prevent it from protruding from the opening of the central hole, further increasing the stability of the annular support. Moreover, compared to the scheme where the second end extends between the outer air bladder and the first end, this reduces the resistance during the movement of the second end, ensuring smooth movement and thus improving the measurement efficiency of the tunnel-type sphygmomanometer.

[0032] 3. The arm tube assembly in this application also includes an elastic cuff located inside the inner air bladder. Both ends of the cuff are fixedly connected to the housing. On the one hand, the cuff can limit the annular support and the inner air bladder to prevent them from protruding from the opening of the central hole, thereby increasing the stability of the annular support and the inner air bladder. On the other hand, when the outer air bladder deflates, the elastic force of the cuff can accelerate the speed at which the annular support recovers its deformation, allowing the inner air bladder to separate from the user's arm in a shorter time, thereby improving the measurement efficiency of the tunnel blood pressure monitor. Furthermore, the cuff can also press the inner air bladder against the user's arm, thereby improving the user's comfort when measuring blood pressure. Attached Figure Description

[0035] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0040] Reference Figures 1 to 12 A tunnel-type blood pressure monitor is disclosed, comprising a main unit 1, an arm cylinder assembly 2, and a hand rest 3. The main unit 1 has a first side and a second side opposite to the first side. The arm cylinder assembly 2 is hinged to the first side and includes a housing 21 with a central hole, an outer air bladder 22 located in the central hole, an annular support 23 located inside the outer air bladder 22, an inner air bladder 24 located inside the annular support 23, and a connector 25 fixedly connected to the outer air bladder 22 and the inner air bladder 24. The outer air bladder 22 is fixedly connected to the wall of the central hole, and the annular support 23 can be rolled up and down under the expansion and contraction of the outer air bladder 22. The hand rest 3 is hinged to the second side.

[0041] Understandably, tunnel-type blood pressure monitors have both an unfolded and a retracted state, as shown in the reference. Figure 2 When the tunnel-type blood pressure monitor is in the unfolded state, both the arm sleeve assembly 2 and the hand rest 3 are located on the side of the main unit 1; refer to Figure 1When the tunnel-type blood pressure monitor is in its retracted state, both the arm tube assembly 2 and the hand rest 3 rotate to the top of the main unit 1, with the hand rest 3 located on the side of the arm tube assembly 2. The annular support 23 is located between the outer air bladder 22 and the inner air bladder 24. When the outer air bladder 22 inflates, it applies pressure to the annular support 23, causing it to deform and coil, thus gradually reducing its diameter. Conversely, when the outer air bladder 22 deflates and contracts, the annular support 23 recovers its deformation and unwinds under its own elastic force, thus gradually increasing its diameter.

[0042] It should be noted that the inner side of the external airbag 22 refers to the side of the external airbag 22 that is away from the wall of the central hole, the inner side of the annular support 23 refers to the side of the annular support 23 that is away from the wall of the central hole, and the inner side of the internal airbag 24 refers to the side of the internal airbag 24 that is away from the wall of the central hole.

[0043] When using the tunnel-type blood pressure timer of this application, the user first inserts their arm into the central hole, with their arm positioned inside the inner air bladder 24. The user's forearm is placed on the hand rest 3, so that the inner air bladder 24 is located at the user's upper arm. The hand rest 3 supports the user's forearm. Then, the main unit 1 is activated, supplying air to the outer air bladder 22, causing the outer air bladder 22 to inflate. The annular support 23 deforms and retracts under the inflating effect of the outer air bladder 22, gradually reducing the diameter of the annular support 23. Eventually, the inner air bladder 24 presses tightly against the user's upper arm. Then, the main unit 1 stops supplying air to the outer air bladder 22 and supplies air to the inner air bladder 24, causing the inner air bladder 24 to gradually inflate and apply pressure to the user's upper arm. Finally, the main unit 1 deflates the inner air bladder 24 and measures the user's blood pressure.

[0044] After the blood pressure measurement is completed, the main unit 1 deflates the external airbag 22, thereby gradually reducing the volume of the external airbag 22. This reduces the pressure exerted by the external airbag 22 on the annular support 23. At this time, the annular support 23 gradually recovers its deformation under its own elastic force, thereby gradually increasing the diameter of the annular support 23. Then, the user can pull their arm out of the central hole.

[0045] Because the tunnel-type blood pressure monitor in this application achieves the goal of pressing the inner airbag 24 against the user's arm by inflating the outer airbag 22, compared with the prior art solution of pressing the airbag against the user's arm by driving one end of the ring bracket 23 through a drive component, it simplifies the structural design of the arm cylinder assembly 2, thereby reducing the volume of the arm cylinder assembly 2, reducing the assembly difficulty of the arm cylinder assembly 2, and also reducing the failure rate of the arm cylinder assembly 2. This, in turn, reduces the volume of the tunnel-type blood pressure monitor, reduces the manufacturing cost of the tunnel-type blood pressure monitor, and reduces the failure rate of the tunnel-type blood pressure monitor, thereby improving the service life of the tunnel-type blood pressure monitor and achieving the effect of improving the user experience.

[0046] Meanwhile, since the outer airbag 22 is fixedly connected to the wall of the central hole, the connector 25 is fixedly connected to the outer airbag 22 and the inner airbag 24, and the annular bracket 23 is located between the inner airbag 24 and the outer airbag 25, the stability of the outer airbag 22 is increased on the one hand, the stability of the annular bracket 23 is increased on the other hand, and it can also ensure the driving effect of the annular bracket 23 on the outer airbag 22 when the outer airbag 22 expands and the driving effect of the annular bracket 23 on the outer airbag 22 when the volume of the outer airbag 22 shrinks; at the same time, it also increases the stability of the inner airbag 24, so that when the diameter of the annular bracket 23 changes, the inner airbag 24 can move with the annular bracket 23.

[0047] Furthermore, since the arm tube assembly 2 is hinged to the first side of the main unit 1 and the hand rest 3 is hinged to the second side of the main unit 1, after the tunnel blood pressure monitor is used, the arm tube assembly 2 and the hand rest 3 can be flipped upwards, thereby moving the tunnel blood pressure monitor from the unfolded state to the stored state, so as to realize the storage of the arm tube assembly 2 and the hand rest 3, thereby reducing the space occupied by the tunnel blood pressure monitor when it is in the stored state, and thus achieving the effect of facilitating the storage and transportation of the tunnel blood pressure monitor.

[0048] This application does not specify a particular method for fixing the outer airbag 22 to the wall of the central hole. Preferably, the outer airbag 22 is attached to the wall of the central hole using double-sided adhesive or Velcro to reduce the assembly difficulty of the outer airbag 22, improve the assembly efficiency of the outer airbag 22, and further reduce the manufacturing cost of the tunnel-type blood pressure monitor. In other embodiments, the outer airbag 22 can also be fixedly connected to the wall of the central hole using fasteners or snap-fit ​​structures.

[0049] This application does not specifically limit the connection relationship between the annular bracket 23 and the connector 25. Preferably, refer to... Figure 5 The ring bracket 23 has a first end fixedly connected to the connector 25 and a second end opposite to the first end. The connector 25 is fixedly connected to the outer airbag 22 and the inner airbag 24, and a through-hole is formed between the inner airbag 24 and the connector 25 for the second end to extend into.

[0050] It is understood that the annular support 23 is fixedly connected to the outer airbag 22 by the connector 25, and the inner airbag 24 is fixedly connected to the annular support 23 by the connector 25; the annular support 23 is made of a flexible sheet material, and the second end being opposite to the first end mentioned above refers to the annular support 23 being in a flattened state.

[0051] Since the first end of the annular bracket 23 is fixedly connected to the connector 25, and the connector 25 is fixedly connected to the outer airbag 22 and the inner airbag 24, the fixed connection between the annular bracket 23 and the outer airbag 22 is realized on the one hand, and the fixed connection between the inner airbag 24 and the annular bracket 23 is realized on the other hand, so as to increase the connection stability between the inner airbag 24 and the annular bracket 23.

[0052] Furthermore, since a through-channel is formed between the inner air bladder 24 and the connector 25 for the second end to extend into, the second end can avoid contact with the inner side of the inner air bladder 24, thereby increasing the accuracy of blood pressure measurement by the tunnel-type blood pressure monitor. On the other hand, the through-channel can guide the second end, thereby increasing the stability of the second end during movement. At the same time, the through-channel can limit the second end to prevent it from protruding from the opening of the central hole, thereby increasing the stability of the ring bracket 23. Moreover, compared with the solution where the second end extends between the outer air bladder 22 and the first end, it can also reduce the resistance during the movement of the second end, thereby ensuring the smoothness of the movement of the second end, and thus improving the measurement efficiency and accuracy of the tunnel-type blood pressure monitor.

[0053] This application does not specifically limit the structure of the connector 25; preferably, refer to... Figure 5 The connector 25 includes an inner connecting layer 251 and an outer connecting layer 252, and a receiving channel is formed between the inner connecting layer 251 and the outer connecting layer 252. The first end extends into the receiving channel, and the outer airbag 22 is fixedly connected to the outer connecting layer 252.

[0054] It is understood that the inner connecting layer 251 is located inside the annular support 23 and between the first end and the second end, while the outer connecting layer 252 is located between the annular support 23 and the outer airbag 22.

[0055] Since a receiving channel is formed between the inner connecting layer 251 and the outer connecting layer 252, the first end extends into the receiving channel, thereby increasing the connection area between the first end and the connector 25, so as to increase the connection stability between the annular bracket 23 and the connector 25.

[0056] This application does not specifically limit the formation method of the inner connecting layer 251 and the outer connecting layer 252. Preferably, the inner connecting layer 251 is formed of fabric located between the annular support 23 and the inner airbag 24, and the outer connecting layer 252 is formed of fabric located between the annular support 23 and the outer airbag 22. That is, the connector 25 is formed of two layers of fabric, and the two layers of fabric are fixedly connected on both sides by stitching or heat fusion. In other embodiments, the inner connecting layer 251 and the outer connecting layer 252 may also be formed of flexible sheet materials.

[0057] This application does not specify the connection method between the connector 25 and the inner air bladder 24. Preferably, both sides of the connector 25 are fixedly connected to the inner air bladder 24 by stitching or heat fusion to increase the connection stability between the connector 25 and the inner air bladder 24 and improve the assembly efficiency of the tunnel-type blood pressure monitor. In other embodiments, the connector 25 can also be fixedly connected to the inner air bladder 24 by riveting or other methods.

[0058] This application does not specify the connection method between the connector 25 and the external airbag 22. Preferably, the connector 25 is fixedly connected to the external airbag 22 by stitching or heat fusion to increase the connection stability between the connector 25 and the external airbag 22 and improve the assembly efficiency of the tunnel-type blood pressure monitor. In other embodiments, the connector 25 can also be fixedly connected to the external airbag 22 by riveting or other methods.

[0059] This application does not specify the method of fixing the first end to the connector 25. Preferably, the first end is fixedly connected to the connector 25 by double-sided tape or Velcro, so as to facilitate the fixing of the first end to the connector 25 together.

[0060] Preferably, the outer connecting layer 252 is provided with a clearance opening so that the first end can be adjusted through the clearance opening to ensure the depth of the first end extending into the receiving channel, thereby ensuring the connection stability between the annular bracket 23 and the connector 25.

[0061] In other implementation examples, the first end can also be fixedly connected to the connector 25 by stitching or heat fusion.

[0062] In other embodiments, the connector 25 is a C-shaped bracket with one end fixedly connected to the outer airbag 22, and both sides of the other end of the bracket are fixedly connected to the inner airbag 24. The first end is fixedly connected to the bracket and located between the inner airbag 24 and the outer airbag 22.

[0063] In other embodiments, the annular support 23 and the connector 25 are not fixedly connected and can move relative to each other; or, the middle part of the annular support 23 in the length direction is fixedly connected to the outer airbag 22 by stitching or heat fusion, thereby achieving a fixed connection between the annular support 23 and the outer airbag 22 on the one hand, and enabling the first end and the second end of the annular support 23 to move relative to each other on the other hand, so that the diameter of the annular support 23 can change under the expansion and contraction of the outer airbag 22; or, the two sides of the first end are directly fixedly connected to the outer airbag 22 by stitching or heat fusion.

[0064] In a preferred embodiment, refer to Figure 4 The arm sleeve assembly 2 also includes an elastic sleeve 26, which is located inside the inner airbag 24, and both ends of the sleeve 26 are fixedly connected to the housing 21.

[0065] Understandably, when the annular support 23 rolls up under the expansion of the external airbag 22, the sleeve 26 can deform under the action of the annular support 23, so that the diameter of the hole structure inside the sleeve 26 decreases; when the external airbag 22 deflates, the annular support 23 rolls up, and the sleeve 26 can recover its deformation under the action of its own elastic force, so that the diameter of the hole structure inside the sleeve 26 increases.

[0066] It should be noted that the above-mentioned "both ends of the sleeve 26 are fixedly connected to the housing 21" means that one end of the sleeve 26 is fixedly connected to one end of the arm tube assembly 2 in the axial direction, and the other end of the sleeve 26 is fixedly connected to the other end of the arm tube assembly 2 in the axial direction.

[0067] Because the cuff 26 is elastic, it is located inside the inner air bladder 24, and both ends of the cuff 26 are fixedly connected to the housing 21. This allows the cuff 26 to limit the movement of the annular support 23 and the inner air bladder 24, preventing them from protruding from the central hole and increasing their stability. Furthermore, when the outer air bladder 22 deflates, the elasticity of the cuff 26 accelerates the recovery of the annular support 23's deformation, allowing the inner air bladder 24 to separate from the user's arm in a shorter time. This enables the user to quickly withdraw their arm from the central hole, improving the measurement efficiency of the tunnel-type blood pressure monitor. Additionally, the cuff 26 allows the inner air bladder 24 to be pressed firmly against the user's arm, enhancing the user's comfort during blood pressure measurement.

[0068] Preferably, the cuff 26 is made of elastic fabric to ensure user comfort when using a tunnel sphygmomanometer to measure blood pressure.

[0069] This application does not specify a particular method for fixing the sleeve 26; preferably, refer to... Figure 4 The housing 21 includes an outer shell 211, an inner shell 212 located inside the outer shell 211, and a cylindrical cap 213 located at one end of the outer shell 211. A central hole is formed inside the inner shell 212, which extends into the interior of the outer shell 211 through one end of the housing 21. Both ends of the sleeve 26 are located between the outer shell 211 and the inner shell 212, so that the sleeve 26 is pressed and fixed by the mutual compression of the outer shell 211 and the inner shell 212. The cylindrical cap 213 is fixedly connected to the end of the outer shell 211 through which the inner shell 212 passes, so that the inner shell 212 is fixed by blocking it. In other embodiments, the sleeve 26 can also be fixedly connected to the housing 21 by riveting or fasteners.

[0070] In a preferred embodiment, refer to Figure 4 The housing 21 has a hinge arm 215, the hinge arm 215 has a hinge shaft 216 passing through the main unit 1, and the hinge shaft 216 is fitted with a damping body 217 located between the hinge arm 215 and the main unit 1.

[0071] It is understandable that after the damper 217 is installed between the hinge arm 215 and the main unit 1, the damper 217 is in a deformed state.

[0072] Since the housing 21 has a hinge arm 215, and the hinge arm 215 has a hinge shaft 216 passing through the main unit 1, the arm cylinder assembly 2 and the main unit 1 are hinged. Since the hinge shaft 216 is fitted with a damping body 217 located between the hinge arm 215 and the main unit 1, the damping body 217 can be used to generate a damping effect when the arm cylinder assembly 2 and the main unit 1 rotate relative to each other, thereby improving the product quality of the tunnel blood pressure monitor and further improving the user experience.

[0073] This application does not specify the location of the articulated arm 215; preferably, refer to... Figure 4 The hinge arm 215 is disposed on the cylinder cover 213, and the outer shell 211 is provided with a support arm 214 corresponding to the hinge arm 215. The hinge arm 215 is fixedly connected to the support arm 214. On the one hand, this achieves a fixed connection between the cylinder cover 213 and the outer shell 211. On the other hand, the support arm 214 can be used to support the hinge arm 215, thereby increasing the stability of the hinge arm 215 and thus increasing the connection stability between the arm cylinder assembly 2 and the main unit 1. In other embodiments, the hinge arm 215 may also be disposed on the outer shell 211.

[0074] This application does not specify the inflation method of the main unit 1 for the outer airbag 22 and the inner airbag 24. Preferably, refer to Figure 3 , Figure 6 , Figure 7 and Figure 8The main unit 1 includes a housing 11 and a first inflation assembly 12. The top end face of the housing 11 is inclined downward along the direction from the second side to the first side. The housing 11 has an installation position located near the second side. The first inflation assembly 12 is used to inflate and deflate the external airbag 22. The first inflation assembly 12 includes at least two first air pumps 121 installed in the installation position.

[0075] It is understandable that the height of the housing 11 on the first side is less than the height of the housing 11 on the second side, so that the space inside the housing 11 near the first side is less than the space inside the housing 11 near the second side.

[0076] Because the housing 11 has a mounting position near the second side, the first inflation assembly 12 includes a first air pump 121 installed at the mounting position. This allows for efficient use of the space inside the housing 11 near the second side, facilitating the installation of the first air pump 121. Furthermore, it allows the first air pump 121 to be closer to the second side, increasing the weight on that side and ensuring a more even weight distribution for the tunnel sphygmomanometer in its stored state. This prevents the tunnel sphygmomanometer from slipping out of the user's hand due to uneven weight distribution, thus improving the user experience.

[0077] Furthermore, since the first inflation component 12 includes at least two first air pumps 121, it improves the inflation efficiency of the main unit 1 on the outer air bag 22, so that the outer air bag 22 can expand quickly, thereby allowing the inner air bag 24 to press against the user's arm in a shorter time, thus improving the measurement efficiency of the tunnel blood pressure monitor. On the other hand, it ensures that the tunnel blood pressure monitor can continue to work even if one of the first air pumps 121 fails, thereby extending the service life of the tunnel blood pressure monitor.

[0078] This application does not specify the number of first air pumps 121. Preferably, two first air pumps 121 are provided to minimize the manufacturing cost of the tunnel-type blood pressure monitor while ensuring the inflation efficiency of the external air bag 22. Of course, in other embodiments, the number of first air pumps 121 may also be different, such as three or four.

[0079] Furthermore, refer to Figure 8 The first inflation assembly 12 also includes a first connector 122, a first pressure sensor, and at least two first deflation valves 123. The first connector 122 has a first communication port connected to the air outlet of the first air pump 121, a first pressure port connected to the first pressure sensor, a first deflation port connected to the first deflation valve 123, and a first air supply port connected to the external airbag 22.

[0080] It is understandable that there are two first connecting ports, each corresponding to one of the two first air pumps 121. Each first connecting port is connected to the air outlet of its corresponding first air pump 121. The number of first vent ports is the same as the number of first vent valves 123. Each first vent port is connected to the air inlet of its corresponding first vent valve 123.

[0081] Specifically, when the outer airbag 22 is inflated so that the inner airbag 24 is pressed against the user's arm, the gas generated by the first air pump 121 enters the first connector 122 through the first connecting port. The gas entering the first connector 122 enters the outer airbag 22 through the first air supply port, causing the outer airbag 22 to gradually expand. At this time, the first pressure sensor detects the air pressure in the first connector 122. When the pressure value of the first pressure sensor reaches the set value, it indicates that the inner airbag 24 has been pressed against the user's arm, and the first air pump 121 stops working. When the outer airbag 22 is deflated, the two first deflation valves 123 open, so that the gas in the outer airbag 22 enters the first connector 122 through the first air supply port, and finally the gas entering the first connector 122 is discharged through the first deflation valves 123.

[0082] Since there are at least two first vent valves 123, the venting efficiency of the external airbag 22 can be improved, so that the external airbag 22 can expel the air inside it in a shorter time, thereby shortening the user's waiting time, further improving the measurement efficiency of the tunnel blood pressure monitor and further improving the user experience.

[0083] Furthermore, since the first connector 122 has a first communication port connected to the air outlet of the first air pump 121, a first pressure port connected to the first pressure sensor, a first vent port connected to the first vent valve 123, and a first air supply port connected to the outer air bag 22, the two first air pumps 121 can be connected to the pressure sensor and the outer air bag 22 through the same component, thereby reducing the number of components required for the tunnel blood pressure monitor, thus further improving the assembly efficiency of the tunnel blood pressure monitor and further reducing the manufacturing cost of the tunnel blood pressure monitor.

[0084] This application does not specify the number of first vent valves 123. Preferably, there are two first vent valves 123 to reduce the manufacturing cost of the tunnel-type blood pressure monitor while ensuring the efficiency of venting the external airbag 22. Of course, in other embodiments, the number of first vent valves 123 may also be different, such as three or four.

[0085] This application does not specifically limit the structure of the first connector 122. Preferably, the first connector 122 is formed by splicing multiple tubes to simplify the structural design of the first connector 122, thereby further reducing the manufacturing cost of the tunnel-type blood pressure monitor. In other embodiments, the first connector 122 can also be formed by splicing multiple tubes and multiple tee connectors.

[0086] This application does not specifically limit the connection method between the first air supply port and the outer airbag 22. Preferably, the first air supply port is connected to the outer airbag 22 through a flexible pipeline to ensure the stability of the connection between the first air pump 121 and the outer airbag 22. In other embodiments, the first air supply port can also be connected to the outer airbag 22 through other components, such as a combination of a tube and a rotary joint.

[0087] Furthermore, refer to Figure 3 , Figure 6 , Figure 7 and Figure 9 The main unit 1 also includes a second inflation assembly 13 for inflating and deflating the inner airbag 24, the second inflation assembly 13 including a second air pump 131 installed at the mounting position.

[0088] It is understood that in this embodiment, the inner airbag 24 and the outer airbag 22 are inflated and deflated by different inflation components.

[0089] Since the second air pump 131 is installed at the mounting position, the second air pump 131 and the first air pump 121 are integrated in the same position in the housing 11, so that the components inside the housing 11 are more regularly distributed, thereby facilitating the maintenance of the tunnel blood pressure monitor. At the same time, it can further make the weight distribution of the tunnel blood pressure monitor in the storage state more uniform.

[0090] Furthermore, refer to Figure 9 The second inflation assembly 13 also includes a second connector 132, a second pressure sensor, and a second deflation valve 133. The second connector 132 has a first communication port connected to the air outlet of the second air pump 131, a second pressure port connected to the second pressure sensor, a second deflation port connected to the second deflation valve 133, and a second air supply port connected to the inner airbag 24.

[0091] Specifically, when the inner airbag 24 is pressed against the user's arm under the expansion of the outer airbag 22, the first air pump 121 stops working, and the second air pump 131 starts working, so that the gas generated by the second air pump 131 enters the second connector 132. The gas entering the second connector 132 enters the inner airbag 24 through the second air supply port, so that the inner airbag 24 expands. At this time, the second pressure sensor detects the air pressure in the second connector 132. When the pressure value of the second pressure sensor reaches the required pressure value, the second air pump 131 stops working, and then the second vent valve 133 opens, so that the gas in the inner airbag 24 enters the second connector 132 through the second air supply port. The gas entering the second connector 132 is discharged through the second vent valve 133. During this process, the second pressure sensor detects the pressure to complete the measurement of the user's blood pressure.

[0092] This application does not specify the number of second vent valves 133. Preferably, there are two second vent valves 133, and the second connector 132 has two second vent ports. The second vent ports correspond one-to-one with the second vent valves 133, and each second vent valve 133 is connected to its corresponding second vent port to increase the maximum exhaust speed of the inner air bladder 24, thereby facilitating the control of the tunnel-type blood pressure monitor. Of course, in other embodiments, there may be one or other numbers of second vent valves 133.

[0093] This application does not specifically limit the structure of the second connector 132. Preferably, the second connector 132 is formed by splicing multiple tubes to simplify the structural design of the second connector 132, thereby further reducing the manufacturing cost of the tunnel-type blood pressure monitor. In other embodiments, the second connector 132 can also be formed by splicing multiple tubes and multiple tee connectors.

[0094] This application does not specifically limit the connection method between the second air supply port and the inner airbag 24. Preferably, the second air supply port is connected to the inner airbag 24 through a flexible pipe to ensure the stability of the connection between the second air pump 131 and the inner airbag 24. In other embodiments, the second air supply port can also be connected to the inner and outer airbags 22 through other components, such as a combination of a pipe and a rotary joint.

[0095] Furthermore, refer to Figure 3 , Figure 6 and Figure 7The housing 11 has an internal accommodating cavity and an mounting cavity. The accommodating cavity contains a circuit board 14 and a battery 15 electrically connected to the circuit board 14. The mounting position is located in the mounting cavity. The arm cylinder assembly 2 and the hand rest 3 are located on opposite sides of the mounting cavity. The housing 11 is provided with a start / stop button 16 electrically connected to the circuit board 14 and a charging interface 17 electrically connected to the circuit board 14. The start / stop button 16 is located at the end of the mounting cavity away from the accommodating cavity, and the charging interface 17 is located at the end of the accommodating cavity away from the mounting cavity.

[0096] It is understood that the charging interface 17 is located in the accommodating cavity, and the wall of the housing 11 is provided with a hole structure for the power cord plug to pass through the charging interface 17; the battery 15 can provide power to the host 1, and the battery 15 can be charged by plugging the power cord plug into the charging interface 17; the start / stop button 16 is located in the mounting cavity, and the wall of the housing 11 is provided with a hole interface for the start / stop button 16 to extend out; the circuit board 14 can control the operation of the first air pump 121, the second air pump 131, the first vent valve 123, and the second vent valve 133 according to the pressure values ​​of the first pressure sensor and the second pressure sensor.

[0097] Since the mounting position is located in the mounting cavity, the hand rest plate 3 and the arm cylinder assembly 2 are located on opposite sides of the mounting cavity, thereby reducing the distance between the first inflation assembly 12 and the second inflation assembly 13 and the arm cylinder assembly 2. This shortens the length of the pipe connecting the first inflation assembly 12 and the outer air bladder 22, as well as the length of the pipe connecting the second inflation assembly 13 and the inner air bladder 24, thereby further reducing the manufacturing cost of the tunnel-type blood pressure monitor.

[0098] Furthermore, since the start / stop button 16 is located at the end of the mounting cavity away from the receiving cavity, and the charging interface 17 is located at the end of the receiving cavity away from the mounting cavity, on the one hand, the charging interface 17 and the start / stop button 16 can avoid each other, so as to facilitate the user to press the start / stop button 16 and to facilitate the user to charge the battery 15. On the other hand, it can also make reasonable use of the circumferential space of the housing 11 to facilitate the assembly of the charging interface 17 and the start / stop button 16, thereby further improving the assembly efficiency of the tunnel blood pressure monitor and further reducing the production and manufacturing cost of the tunnel blood pressure monitor.

[0099] Preferably, both the first pressure sensor and the second pressure sensor are provided with a circuit board 14 to increase the stability of the first pressure sensor and the second pressure sensor, and the first pressure port is connected to the first pressure sensor through a flexible tube, and the second pressure port is connected to the second pressure sensor through a flexible tube.

[0100] Furthermore, refer to Figure 6 and Figure 7An emergency stop module 18 electrically connected to the circuit board 14 is provided in the accommodating cavity. The emergency stop module 18 is located near the second side and has an emergency button that extends out of the housing 11.

[0101] Understandably, the wall of the housing 11 is provided with a hole structure for the emergency button to extend, so that the user can stop the main unit 1 in an emergency by pressing the emergency button.

[0102] Because the accommodating cavity is equipped with an emergency stop module 18 that is electrically connected to the circuit board 14, the emergency stop module 18 has an emergency button that extends out of the housing 11. In an emergency, the user can press the emergency button to stop the tunnel blood pressure monitor from working, thereby further improving the user experience.

[0103] Furthermore, since the emergency stop module 18 is located close to the second side, the space of the accommodating cavity near the second side can be reasonably utilized to increase the structural compactness of the main unit 1, thereby achieving the effect of facilitating the miniaturization design of the tunnel-type blood pressure monitor; at the same time, the emergency button is located on the side of the main unit 1 away from the user, so as to avoid the situation where the user accidentally touches it and causes the main unit 1 to stop working.

[0104] This application does not specifically limit the formation of the mounting position. Preferably, the mounting position is formed by a rib provided in the mounting cavity. The rib is provided with a recessed groove that matches the outer contour of the first air pump 121 and the second air pump 131, so that the rib can be used to support and limit the first air pump 121 and the second air pump 131, thereby increasing the stability of the first air pump 121 and the second air pump 131. In other embodiments, the mounting position may also be formed by other structures provided in the receiving cavity.

[0105] The better one is to refer to Figure 3 The housing 11 includes a bottom shell 111 and a top cover 112. The bottom shell 111 has an internal mounting cavity and a receiving cavity. The main unit 1 also includes a display screen 19 electrically connected to the circuit board 14. The display screen 19 is located in the receiving cavity. The top cover 112 has a transparent area corresponding to the display screen 19. The circuit board 14 can process the pressure value of the second pressure sensor and generate the user's blood pressure value, which is then displayed on the display screen 19 so that the user can view the blood pressure value through the transparent area.

[0106] In other embodiments, the main unit 1 includes a housing 11 and an inflation assembly disposed inside the housing 21. The inflation assembly includes an air pump, a switching valve, two pressure sensors, and two deflation valves. The air pump is connected to the outer airbag 22 and the inner airbag 24 through the switching valve. The switching valve can switch the air pump from being connected to the outer airbag 22 to being connected to the inner airbag 24, and the switching valve can also switch the air pump from being connected to the inner airbag 24 to being connected to the outer airbag 22. One pressure sensor is connected to the outer airbag 22 to detect the air pressure in the outer airbag 22, and the other pressure sensor is connected to the inner airbag 24 to detect the air pressure in the inner airbag 24. One deflation valve is connected to the outer airbag 22 to deflate the outer airbag 22, and the other deflation valve is connected to the inner airbag 24 to deflate the inner airbag 24.

[0107] In a preferred embodiment, refer to Figure 3 and Figure 10 The handrest 3 is provided with a handhold 31 for the user to hold, and the handhold 31 is located at the end of the handrest 3 away from the main unit 1.

[0108] Since the handrest 3 is provided with a handhold 31 for the user to hold, when the user moves the tunnel blood pressure monitor, the user can hold the handhold 31 with their hand to move the tunnel blood pressure monitor by gripping the handhold 31, thereby making it easier for the user to move the tunnel blood pressure monitor and further improving the user experience.

[0109] Furthermore, since the handheld part 31 is located at the end of the hand rest 3 that is far away from the main unit 1, the handheld part 31 can avoid the main unit 1, thereby making it easier for the user to grip the handheld part 31 and further improving the user experience.

[0110] This application does not specifically limit the structure of the handheld part 31; preferably, refer to... Figure 3 and Figure 10 The handle 31 is a hand-holding hole provided on the handrest 3 to facilitate the user's grip on the handrest 3, and at the same time, it can reduce the raw materials required during the production of the handrest 3, thereby further reducing the production cost of the tunnel-type blood pressure monitor. In other embodiments, the handle 31 may also be a protruding rib provided on the back of the handrest 3 to block the user's hand.

[0111] In a preferred embodiment, refer to Figure 6 , Figure 10 , Figure 11 and Figure 12The housing 11 includes a bottom shell 111, a top cover 112, and a connecting arm 114. The bottom shell 111 has a passage 113 on the second side. The connecting arm 114 extends into the interior of the bottom shell 111 through the passage 113. The connecting arm 114 is provided with a limiting groove 115. A limiting cover 116 is fixedly connected inside the bottom shell 111. The limiting cover 116 is provided with a limiting rib 117 extending into the limiting groove 115. The hand rest 3 is hinged to the end of the connecting arm 114 located outside the bottom shell 111. This reduces the molding difficulty of the bottom shell 111, thereby reducing the manufacturing cost of the tunnel blood pressure monitor. It also facilitates the assembly of the hand rest 3, thereby improving the assembly efficiency of the tunnel blood pressure monitor.
