Description

Technical Field

[0001] This utility model relates to the field of blood pressure measurement technology, and in particular to a blood pressure monitor component. Background Technology

[0002] An ambulatory blood pressure monitor, also known as a blood pressure recorder or ambulatory blood pressure monitor, is a medical device used to continuously monitor a patient's blood pressure changes for 24 hours without interfering with their daily activities. An ambulatory blood pressure monitor consists of a main unit and a cuff. The main unit is attached to the cuff. To measure blood pressure, the cuff is wrapped around the patient's upper arm and inflated to a certain extent to compress the upper arm, thus stopping blood flow. The cuff is then gradually deflated until blood flow resumes. During this process, the ambulatory blood pressure monitor records the changes in blood pressure and saves the data.

[0003] After blood pressure measurement or during cleaning and maintenance, the cuff must be removed from the main unit. Current ambulatory blood pressure monitors typically use clips to secure the main unit to the cuff. This involves multiple male clips on the back panel and corresponding female clips on the main unit, with through holes in the cuff. During installation, multiple male clips need to pass through these holes and engage with the female clips. Since the female clips are located on the side of the main unit facing the cuff, and the male clips are located on the side of the back panel facing the main unit, disassembly is inconvenient. Utility Model Content

[0004] The main purpose of this invention is to propose a blood pressure monitor assembly that aims to solve the technical problem of inconvenient disassembly of the main unit and the cuff.

[0005] To achieve the above objectives, the blood pressure monitor assembly proposed in this utility model includes:

[0006] A snap fastener is configured to connect with a cuff. The snap fastener has an inlet / outlet groove, a limiting groove, and a through groove. The limiting groove is formed in the groove wall of the inlet / outlet groove. One end of the through groove is connected to the inlet / outlet groove. The depth direction of the through groove is connected to the limiting groove. The width of the through groove is smaller than the width of the limiting groove.

[0007] A locking member includes a connecting portion and a limiting portion. The width of the connecting portion is smaller than the width of the through groove. The connecting portion has a first connecting side and a second connecting side disposed opposite to each other. The first connecting side is configured to connect to the main unit of the dynamic blood pressure monitor, and the second connecting side is connected to the limiting portion. The width of the limiting portion is greater than the width of the through groove, and the width of the limiting portion is smaller than the width of the limiting groove, so that the limiting portion can enter the limiting groove through the inlet / outlet groove, and the connecting portion can enter the inlet / outlet groove, the limiting groove, and the through groove.

[0008] Optionally, the connecting portion has a stop groove that extends along the direction of the limiting portion;

[0009] The groove wall of the through groove is provided with a limiting protrusion, which corresponds to the stop groove and engages with the stop groove.

[0010] Optionally, one side of the through groove along its length has a limiting wall, and the limiting protrusion is formed in the limiting wall;

[0011] The limiting protrusion has a first convex arc surface, which transitions in an arc shape from the end of the limiting protrusion away from the limiting wall toward the limiting wall.

[0012] The stop groove has a first concave arc surface, which transitions in an arc shape from the bottom of the stop groove along the edge of the stop groove.

[0013] Optionally, there are two limiting protrusions, which are located on opposite sides of the through groove and are arranged opposite to each other.

[0014] There are two stop grooves, and the stop grooves are correspondingly provided with the limiting protrusions.

[0015] Optionally, the engaging component has a first deformation groove, which is adjacent to the limiting protrusion. The length direction of the first deformation groove is directly opposite to the limiting protrusion. The length of the first deformation groove is greater than or equal to 7 mm, and the depth of the first deformation groove is greater than the depth of the through groove.

[0016] Optionally, the distance between the first deformation groove and the through groove is greater than or equal to 1 mm and less than or equal to 2 mm.

[0017] Optionally, a second deformation groove is provided on the side of the limiting part opposite to the connecting part, and the second deformation groove extends along the length direction of the limiting part.

[0018] Optionally, there are two second deformation grooves, which are arranged at intervals along the length of the limiting portion, so that a supporting rib is formed between the two second deformation grooves, and the supporting rib is correspondingly provided with the stop groove.

[0019] Optionally, the limiting part is trapezoidal, and the limiting groove is trapezoidal corresponding to the limiting part.

[0020] Optionally, at least two abutting protrusions are also provided on one side of the groove wall along the length direction of the groove, and the two abutting protrusions are arranged at intervals along the length direction of the groove.

[0021] This utility model relates to a blood pressure monitor assembly. A locking component connects to the cuff, and the locking component has an inlet / outlet groove, a limiting groove, and a through groove. The inlet / outlet groove communicates with the outside. The limiting groove is located on one side of the inlet / outlet groove's width, preventing direct communication with the outside. The through groove is located on the side of the locking component with the inlet / outlet groove, and its depth direction communicates with the limiting groove. The through groove and the limiting groove are directly opposite each other, allowing the limiting groove to communicate with the outside. The first connecting side of the connecting part connects to the main unit, and the second connecting side connects to the limiting part. The width of the limiting part is greater than the width of the through groove, but less than the widths of the limiting groove and the inlet / outlet groove. Thus, when the limiting part is positioned in the limiting groove via the inlet / outlet groove, it cannot directly exit the limiting groove via the through groove. At this point, the main unit can be mounted on the cuff using the locking component and the fastening component. When removing the main unit from the sleeve, simply remove the limiting part from the limiting groove and the inlet / outlet groove to complete the removal of the main unit from the sleeve, which improves the convenience of installing and removing the main unit from the sleeve.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] This utility model is a blood pressure monitor assembly for use in an ambulatory blood pressure monitor, which includes a main unit 200 and a cuff 100. The blood pressure monitor assembly is used to mount the main unit 200 onto the cuff 100.

[0039] This utility model proposes a blood pressure monitor component.

[0040] In the embodiments of this utility model, such as Figures 1 to 9 As shown, the blood pressure monitor assembly includes:

[0041] The fastening component 1 is configured to connect with the cuff 100. The fastening component 1 has an inlet / outlet groove 11, a limiting groove 12, and a through groove 13. The limiting groove 12 is formed in the groove wall of the inlet / outlet groove 11. One end of the through groove 13 is connected to the inlet / outlet groove 11. The depth direction of the through groove 13 is connected to the limiting groove 12. The width of the through groove 13 is smaller than the width of the limiting groove 12.

[0042] The locking member 2 includes a connecting part 21 and a limiting part 22. The width of the connecting part 21 is smaller than the width of the through groove 13. The connecting part 21 has a first connecting side and a second connecting side disposed opposite to each other. The first connecting side is configured to connect to the main unit 200 of the dynamic blood pressure monitor. The second connecting side is connected to the limiting part 22. The width of the limiting part 22 is larger than the width of the through groove 13, and the width of the limiting part 22 is smaller than the width of the limiting groove 12, so that the limiting part 22 can enter the limiting groove 12 through the inlet / outlet groove 11. The connecting part 21 can enter the inlet / outlet groove 11, the limiting groove 12, and the through groove 13.

[0043] The locking component 1 is plate-shaped and is used to engage with the locking component 2 and to securely connect with the cuff 100 of the ambulatory blood pressure monitor. The locking component 1 can be connected to the cuff 100 by screws, adhesive, riveting, etc. The cuff 100 can be fixed to one side of the locking component 1, or it can be clamped into the locking component 1. When the locking component 1 secures the cuff 100 by clamping, the locking component 1 includes a first clamp and a second clamp, which clamp the cuff 100 by screws or adhesive.

[0044] The engaging component 1 has an inlet / outlet groove 11, a limiting groove 12, and a through groove 13 on one side. The inlet / outlet groove 11 extends along the length of the engaging component 1. A limiting groove 12 is formed on one side wall of the inlet / outlet groove 11 in the width direction. The limiting groove 12 extends along the length of the engaging component 1 in the depth direction. The width of the limiting groove 12 is directly opposite to the width of the inlet / outlet groove 11, and the width of the limiting groove 12 is approximately equal to the width of the inlet / outlet groove 11. A through groove 13 is formed on the side of the engaging member 1 with the inlet / outlet groove 11. One end of the through groove 13 is connected to one end of the inlet / outlet groove 11, and the width direction of the through groove 13 is directly opposite to the width direction of the inlet / outlet groove 11. Simultaneously, the depth direction of the through groove 13 is connected to the limiting groove 12. The through groove 13 and the limiting groove 12 are directly opposite each other, forming a T-shape after they are connected, so that the T-shaped locking member 2 can enter the limiting groove 12 through the inlet / outlet groove 11 and the through groove 13. To prevent the locking member 2 from exiting the limiting groove 12 through the through groove 13, the width of the through groove 13 is smaller than the width of the limiting part 22. The specific width of the through groove 13 only needs to restrict the limiting part 22 from exiting the limiting groove 12 through the through groove 13. It should be noted that when the cuff 100 is provided on one side of the engaging member 1, the inlet / outlet groove 11 and the through groove 13 are located on the side of the engaging member 1 opposite to the side where the cuff 100 is provided.

[0045] The overall structure of the locking member 2 can be T-shaped, L-shaped, etc., and this embodiment will use a T-shaped structure as an example. That is, the connecting part 21 and the limiting part 22 are connected in a T-shape to correspond to the shape after the through groove 13 and the limiting groove 12 are connected. The connecting part 21 is block-shaped, and its transverse cross-section is square, rectangular, or trapezoidal. The first connecting side and the second connecting side of the connecting part 21 are located on opposite sides in the height direction of the connecting part 21. The height direction of the connecting part 21 is the direction between the limiting part 22 of the connecting part 21 and the main unit 200 of the dynamic blood pressure monitor. The connection method between the connecting part 21 and the main unit 200 of the dynamic blood pressure monitor can be integrally formed, or it can be connected by glue or screws, etc. There is no specific limitation here, as long as the connecting part 21 and the main unit 200 of the dynamic blood pressure monitor can be fixedly connected.

[0046] The limiting part 22 and the connecting part 21 can be connected in one piece or by screws, etc., without specific restrictions. The length of the limiting part 22 extends along the length direction of the connecting part 21. At the same time, the width of the limiting part 22 is greater than the width of the connecting part 21. That is, after the limiting part 22 and the connecting part 21 are connected, the width edge of the limiting part 22 protrudes beyond the width edge of the connecting part 21 (that is, the connecting part 21 and the limiting part 22 are T-shaped after being connected). Furthermore, the width of the limiting part 22 is less than the groove width of the inlet / outlet groove 11 and the groove width of the limiting groove 12, so that the limiting part 22 can enter the inlet / outlet groove 11 and the limiting groove 12.

[0047] In use, the locking member 2 is inserted into the inlet / outlet slot 11. The locking member 2 enters the limiting slot 12 through the inlet / outlet slot 11 and the through slot 13. After the locking member 2 enters the limiting slot 12, because the width of the limiting part 22 of the locking member 2 is greater than the width of the through slot 13, the limiting part 22 cannot exit the limiting slot 12 through the through slot 13. At this time, the main unit 200 can be installed on the cuff 100 through the locking member 2 and the locking member 1. When the main unit 200 needs maintenance, simply move the limiting part 22 from the limiting slot 12 into the inlet / outlet slot 11 and out of the inlet / outlet slot 11 to the outside to remove the main unit 200 from the cuff 100, thus improving the convenience of installation and removal. It should be noted that there are several ways for the limiting part 22 to exit the limiting groove 12. One method is to install magnets on the groove wall of the limiting groove 12 facing the inlet / outlet groove 11, with corresponding magnets on the limiting part 22. The two magnets attract each other, causing the limiting part 22 to exit the limiting groove 12. Alternatively, a through hole can be made in the engaging part 1, penetrating the groove wall of the limiting groove 12 along its length and positioned close to the inlet / outlet groove 11. In this way, the limiting part 22 will exit the limiting groove 12 completely. After all the objects are located on the side of the through hole away from the inlet / outlet groove 11, a screw or wire or other strip-shaped object is inserted into the limiting groove 12 through the through hole. At this time, the screw or wire or other strip-shaped object can prevent the limiting part 22 from exiting the limiting groove 12, thereby achieving the purpose of limiting the limiting part 22. Alternatively, the limiting part 22 can be restricted from exiting the limiting groove 12 by a tight fit. That is, soft rubber is provided on the groove wall of the through groove 13 near the inlet / outlet groove 11 to increase the contact with the limiting part 22, thereby increasing the friction between the limiting part 22 and the limiting groove 12.

[0048] This utility model blood pressure monitor assembly connects the locking member 1 to the cuff 100. The locking member 1 has an inlet / outlet groove 11, a limiting groove 12, and a through groove 13. The inlet / outlet groove 11 communicates with the outside. The limiting groove 12 is formed on one side of the groove wall in the width direction of the inlet / outlet groove 11, so that the limiting groove 12 cannot directly communicate with the outside. The through groove 13 is formed on the side of the locking member 1 with the inlet / outlet groove 11, and the depth direction of the through groove 13 communicates with the limiting groove 12. At the same time, the through groove 13 is directly opposite the limiting groove 12, so that the limiting groove 12 can also communicate with the outside through the through groove 13. The first connecting side of the connecting part 21 is connected to the main unit 200, and the second connecting side is connected to the limiting part 22. The width of the limiting part 22 is greater than the width of the through groove 13, and the width of the limiting part 22 is less than the width of the limiting groove 12 and the inlet / outlet groove 11. Thus, when the limiting part 22 is set in the limiting groove 12 through the inlet / outlet groove 11, the limiting part 22 cannot directly exit the limiting groove 12 through the through groove 13. At this time, the main unit 200 can be installed on the cuff 100 through the engaging part 1 and the locking part 2. When removing the main unit 200 from the cuff 100, it is only necessary to remove the limiting part 22 from the limiting groove 12 and the inlet / outlet groove 11 to complete the removal of the main unit 200 from the cuff 100, which improves the convenience of installing and removing the main unit 200 from the cuff 100.

[0049] In some examples, such as Figure 7 and Figure 8 As shown, the connecting part 21 has a stop groove 211, which extends along the direction of the limiting part 22; the groove wall of the through groove 13 is provided with a limiting protrusion 131, which corresponds to the stop groove 211, and the limiting protrusion 131 engages with the stop groove 211.

[0050] The stop groove 211 is used to cooperate with the limiting protrusion 131 to limit the exit of the limiting part 22 from the limiting groove 12. The stop groove 211 extends along the height direction of the connecting part 21, which is the direction in which the connecting part 21 connects the limiting part 22 and the main unit 200. The shape of the stop groove 211 can be V-shaped or rectangular, etc., without specific limitations, as long as it can limit the exit of the limiting part 22 from the limiting groove 12 when cooperating with the limiting protrusion 131. The limiting protrusion 131 is provided on one side of the groove wall along the length direction of the inlet / outlet groove 11. The shape of the limiting protrusion 131 can be V-shaped or rectangular, etc., without specific limitations. The limiting protrusion 131 may or may not be elastic. For example, when the connecting portion 21 and the through groove 13 are in clearance fit, and the connecting portion 21 has a deformation groove on the side facing the width direction of the through groove 13, the deformation groove passes through the connecting portion 21 and extends to the main unit 200 and the limiting portion 22. In this way, when the limiting protrusion 131 abuts against the connecting portion 21, the limiting portion 22 can deform through the deformation groove, thereby reducing the width of the limiting portion 22, allowing the connecting portion 21 to enter the through groove 13. When the limiting protrusion 131 is elastic, the connecting portion 21 and the through groove 13 may also have a gap, so that the limiting portion 22 has corresponding space when the limiting protrusion 131 deforms.

[0051] In some examples, such as Figure 8 and Figure 9 As shown, the through groove 13 has a limiting wall on one side along its length, and the limiting protrusion 131 is formed on the limiting wall; the limiting protrusion 131 has a first convex arc surface 1311, which arcs from the end of the limiting protrusion 131 away from the limiting wall toward the limiting wall; the stop groove 211 has a first concave arc surface 2111, which arcs from the bottom of the stop groove 211 along the edge of the stop groove 211.

[0052] The limiting protrusion 131 is V-shaped overall, or the end of the limiting protrusion 131 away from the limiting wall is semi-circular. When the limiting protrusion 131 is V-shaped overall, the end of the limiting protrusion 131 away from the limiting wall has an arc surface, which transitions in an arc from the end of the limiting protrusion 131 away from the limiting wall toward the limiting wall. At the same time, the stop groove 211 is a V-shaped groove, and the stop groove 211 transitions in an arc from the bottom of the groove to the edge of the groove. In this way, when the limiting part 22 exits the limiting groove 12, the limiting protrusion 131 can be prevented from wearing excessively due to excessive resistance.

[0053] In some examples, as shown in the figure, there are two limiting protrusions 131, each located on opposite walls of the through groove 13, and the two limiting protrusions 131 are arranged opposite each other; there are two stop grooves 211, which are correspondingly arranged with the limiting protrusions 131. Providing two limiting protrusions 131 helps improve the stability of the limiting part 22.

[0054] In some examples, such as Figure 9 As shown, the engaging member 1 has a first deformation groove 14, which is adjacent to the limiting protrusion 131. The length direction of the first deformation groove 14 is directly opposite to the limiting protrusion 131. The length of the first deformation groove 14 is greater than or equal to 7mm, and the depth of the first deformation groove 14 is greater than the depth of the through groove 13.

[0055] In this real-time example, the limiting protrusion 131 is not elastic. The first deformation groove 14 is provided so that a deformation rib is formed between the first deformation groove 14 and the through groove 13. The first deformation groove 14 is the space for the elastic deformation of the deformation rib, so that when the limiting protrusion 131 abuts against the connecting part 21, the limiting protrusion 131 avoids the deformation of the deformation rib, which facilitates the entry of the limiting part 22 into the through groove 13. The length direction of the first deformation groove 14 is parallel to the length direction of the through groove 13, and the limiting protrusion 131 is positioned directly opposite the middle of the length direction of the first deformation groove 14. The length of the first deformation groove 14 is greater than or equal to 7mm, which can improve the flexibility of the deformation rib. At the same time, the width of the first deformation groove 14 is greater than or equal to the height of the limiting protrusion 131 (the height of the limiting protrusion 131 is the distance by which the limiting protrusion 131 protrudes through the groove wall of the groove 13). Thus, when the deformation rib deforms due to the limiting protrusion 131, the first deformation groove 14 has sufficient deformation space.

[0056] In some examples, such as Figure 8 As shown, the distance between the first deformation groove 14 and the through groove 13 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0057] When the distance between the first deformation groove 14 and the through groove 13 is less than 1mm, the groove wall rigidity of the deformation rib is insufficient, causing the limiting protrusion 131 and the stop groove 211 to be unstablely engaged. When the distance between the first deformation groove 14 and the through groove 13 is greater than 1mm, the elasticity of the deformation rib is insufficient, making it difficult for the connecting part 21 to enter the through groove 13, which is not conducive to installation and disassembly.

[0058] In some examples, such as Figure 4 As shown, the limiting part 22 has a second deformation groove 221 on the side opposite to the connecting part 21, and the second deformation groove extends along the length direction of the limiting part 22.

[0059] In this embodiment, the limiting part 22 is tightly fitted with the limiting groove 12, and a second deformation groove 221 is provided at the end of the limiting part 22 away from the connecting part 21. The second deformation groove 221 extends to the connecting part 21 in the depth direction and extends along the length direction of the limiting part 22 in the length direction. In this way, when the limiting part 22 is tightly fitted, the limiting part 22 can deform, preventing the limiting part 22 from being over-pressed, and improving the stability of the locking member 2 in the engaging member 1.

[0060] In some examples, such as Figure 4 As shown, there are two second deformation grooves 221, which are arranged at intervals along the length of the limiting part 22, so that a support rib 222 is formed between the two second deformation grooves 221. The support rib 222 is correspondingly provided with the stop groove 211. The support rib 222 is used to enhance the structural strength of the limiting part 22.

[0061] In some examples, such as Figure 3 and Figure 4 As shown, the limiting part 22 is trapezoidal, and the limiting groove 12 is trapezoidal corresponding to the limiting part 22. The trapezoidal shape of the limiting part 22 and the trapezoidal shape of the limiting groove 12 help improve the stability of the locking member 2.

[0062] In some examples, as shown in the figure, at least two abutting protrusions 133 are also provided on one side of the groove wall along the length direction of the groove 13, and the two abutting protrusions 133 are arranged at intervals along the length direction of the groove 13.

[0063] The first abutment protrusion 133 is used to prevent the engaging member 1 from loosening, thereby improving the stability of the connecting part 21.

[0064] In some examples, such as Figure 8 and Figure 9As shown, the through groove 13 has a limiting wall on one side along its length, and the abutting protrusion 133 protrudes from the limiting wall; the abutting protrusion 133 has a second convex arc surface, which extends in an arc shape from the end of the abutting protrusion 133 away from the limiting wall toward the limiting wall. The provision of the second convex arc surface helps to reduce the friction between the first abutting protrusion 133 and the connecting portion 21.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
