Description

Technical Field

[0001] This utility model belongs to the technical field of traditional Chinese medicine pulse diagnosis, and in particular relates to an airbag for a wristband-type traditional Chinese medicine pulse diagnosis instrument. Background Technology

[0002] In the field of pulse diagnosis in Traditional Chinese Medicine, traditional methods mainly rely on the physician's fingers directly touching the patient's wrist to feel the pulse and assess the patient's health by sensing the pulse's pulsation. However, this traditional method has many limitations.

[0003] On the one hand, traditional pulse diagnosis relies heavily on the physician's experience and subjective feelings. Different physicians may have different judgments on the same pulse, leading to a lack of objectivity and accuracy in the diagnostic results. Moreover, physicians may find it difficult to accurately detect some subtle changes in the pulse, thus affecting the accuracy of the diagnosis.

[0004] On the other hand, with the development of modern medical technology, higher demands are placed on the objectivity and standardization of traditional Chinese medicine pulse diagnosis. Traditional pulse diagnosis methods are unable to meet the needs of large-scale, rapid, and accurate diagnosis, thus limiting the application and development of traditional Chinese medicine pulse diagnosis in the modern medical environment.

[0005] To overcome the shortcomings of traditional pulse diagnosis methods, some techniques and devices that utilize auxiliary tools for pulse diagnosis have emerged in recent years. Among them, the wristband-type TCM pulse diagnosis instrument, as a novel pulse diagnosis device, has received widespread attention. The wristband-type TCM pulse diagnosis instrument typically uses structures such as air bladders to simulate the process of a physician pressing the pulse with their fingers, and uses pressure sensors and other devices to collect pulse information, thereby achieving objectivity and standardization in pulse diagnosis.

[0006] However, existing wristband-type TCM pulse diagnosis instruments have some problems with their airbags. Some airbags use a single-layer membrane structure, which has poor sealing and stability, making them prone to air leakage and affecting the accurate acquisition of pulse information. Moreover, some airbags have unreasonable functional integration designs, with unscientific placement of the air inlet / outlet nozzles and pressure detection nozzles, leading to poor gas injection and discharge, or unstable connection between the pressure sensor and the airbag cavity, thus affecting the measurement accuracy and reliability of the pulse diagnosis instrument.

[0007] In addition, existing airbags lack a reasonable layout and design in their internal structure. For example, there is no dedicated wiring channel, which leads to a messy wiring arrangement inside the airbag. This not only increases the difficulty of assembly but also easily causes wiring failures and reduces the service life of the airbag.

[0008] Therefore, we need to develop an airbag for a wristband-type TCM pulse diagnosis instrument that has good sealing performance, reasonable functional integration, and optimized internal structure. Utility Model Content

[0009] In view of the problems existing in the prior art, this utility model provides a sac for a traditional Chinese medicine pulse diagnosis instrument.

[0010] This invention is implemented as follows: a gas bladder for a traditional Chinese medicine pulse diagnosis instrument, characterized by: comprising a double-layer flexible membrane, the double-layer flexible membrane being sealed around its perimeter by heat fusion to form a closed gas bladder cavity; a superimposed sealing heat-sealed area is provided in the middle of the gas bladder cavity, the two ends of the superimposed sealing heat-sealed area being connected to the gas bladder cavity, and a through wiring channel is provided within the superimposed sealing heat-sealed area; a functional integration part is provided in the middle region of the double-layer flexible membrane, the functional integration part including: an inlet / outlet nozzle, penetrating a single-layer flexible membrane and communicating with the gas bladder cavity, for gas injection and discharge; and a pressure detection nozzle, spaced apart from the inlet / outlet nozzle, penetrating the single-layer flexible membrane and communicating with the gas bladder cavity, for connecting a pressure sensor.

[0012] More preferably, the inlet / outlet nozzles and pressure detection nozzles are provided with inlet / outlet clearance grooves at their ends within the airbag cavity.

[0013] More preferably, the intake and exhaust clearance grooves are provided with N in the circumferential direction, where N is greater than or equal to 2.

[0014] In a further preferred embodiment, the line connecting the center of the air inlet / outlet nozzle and the pressure detection nozzle is perpendicular to the horizontal center line of the airbag.

[0015] More preferably, the outer diameter of the air inlet / outlet nozzle is 4-7mm, the inner diameter is 2-3mm, and the height is 3-6mm; the outer diameter of the pressure detection nozzle is 4-7mm, the inner diameter is 2-3mm, and the height is 5-10mm.

[0016] More preferably, the distance between the cable channel and the center line connecting the inlet / outlet nozzle and the pressure detection nozzle is 6-15mm.

[0017] More preferably, the width of the cabling channel is 0.1-2mm.

[0018] More preferably, the wiring channel of the overlapping and sealing heat-sealing area is provided with an insulating layer, which is preferably a flexible PVC film.

[0019] More preferably, the flexible membrane is made of PVC material, and the thickness of a single layer of flexible membrane is 0.1-0.5 mm; and the outer surface of the flexible membrane is smooth and flat, and at least the inner surface of the heat-sealed edge of the flexible membrane has a textured surface.

[0020] The advantages and technical effects of this utility model are as follows: This utility model relates to an airbag for a wristband-type traditional Chinese medicine pulse diagnosis instrument, and its overall technical effects are significant, specifically reflected in the following aspects:

[0021] First, the double-layer flexible membrane design effectively prevents gas leakage and ensures stable air pressure within the air bladder, providing a solid foundation for accurately simulating the pressure of a physician's finger pressing on the pulse. Simultaneously, the double-layer membrane enhances resistance to damage, extends the lifespan of the air bladder, and improves the reliability and durability of the pulse diagnostic instrument.

[0022] Secondly, the heat-sealing technology creates a closed inner cavity for the airbag, ensuring a tight seal, preventing gas leakage from the edges, and ensuring stable and accurate pressure control. The closed cavity provides independent space for gas injection and expulsion, improving the accuracy of pulse diagnosis.

[0023] Furthermore, the overlapping and sealing heat-sealing zone enhances the structural stability of the airbag, tightly bonding the two membrane layers, increasing overall strength, and better withstanding internal air pressure and external pressure.

[0024] In addition, the through-duct provides dedicated space for cable layout, allowing the cables to be arranged in an orderly manner, reducing mutual interference and wear, lowering the probability of failure, and facilitating cable installation and maintenance.

[0025] The design of the functional integration unit, including the air inlet and outlet nozzles and the pressure detection nozzle, enables the pulse diagnostic instrument to easily control the air pressure inside the airbag and accurately measure air pressure changes, providing accurate data support for pulse diagnosis.

[0026] Further optimized technical features, such as the extension length of the air inlet / outlet nozzle and pressure detection nozzle, the end air inlet / outlet clearance groove, the perpendicularity of the centerline to the horizontal centerline of the airbag, specific size design, the distance and width of the wiring channel to the centerline, and the insulation layer, all further improve the measurement accuracy and reliability of the pulse diagnostic instrument.

[0027] In summary, the airbag designed in this utility model has advantages such as good sealing and structural stability, and can be applied to both wristband-type TCM pulse diagnosis instruments and cylindrical pulse diagnosis instruments. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0035] Please see Figures 1 to 5 A traditional Chinese medicine pulse diagnosis instrument uses an air bladder, comprising a double-layered flexible membrane 1. The double-layered membrane effectively prevents gas leakage, ensuring stable air pressure within the air bladder cavity and providing a basis for accurately simulating the pressure of a physician's finger pressing on the pulse. Simultaneously, the double-layered flexible membrane has stronger resistance to damage when subjected to external pressure or friction, extending the lifespan of the air bladder and improving the overall reliability and durability of the pulse diagnosis instrument. The double-layered flexible membrane is sealed around its perimeter by heat fusion to form a closed air bladder cavity 11. Heat fusion sealing is a reliable and efficient sealing method, sealing the perimeter of the double-layered flexible membrane to form a closed air bladder cavity. This sealing method ensures the airtightness of the air bladder cavity, preventing gas leakage from the edges and ensuring stable and accurate control of the air pressure within the air bladder. The closed air bladder cavity provides an independent space for gas injection and discharge, enabling the pulse diagnosis instrument to precisely control the pressure applied to the wrist pulse, improving the accuracy of pulse diagnosis.

[0036] A superimposed sealing heat-sealing area 12 is provided in the middle of the airbag's inner cavity. The two ends of the superimposed sealing heat-sealing area are connected to the inner cavity of the airbag, which further enhances the structural stability of the airbag. The superimposed sealing heat-sealing allows the double-layer membrane to be tightly bonded in this area, which also increases the overall strength of the airbag, enabling it to better withstand internal air pressure and external pressure.

[0037] A through-flow cable routing channel 13 is provided within the overlapping and sealing heat-sealing area, offering dedicated space for cable arrangement. This design allows for orderly cable arrangement, preventing messy cable distribution on the airbag surface, reducing mutual interference and wear between cables, and lowering the probability of cable failure. Simultaneously, the through-flow cable routing channel facilitates cable installation and maintenance, improving production efficiency and product reliability.

[0038] The middle region of the double-layer flexible membrane is equipped with a functional integration section, which includes an air inlet / outlet nozzle 14 that penetrates the single-layer flexible membrane and communicates with the inner cavity of the air bladder for gas injection and discharge. This design allows the pulse diagnostic instrument to easily control the air pressure inside the air bladder. By injecting or expelling gas into the air bladder, it simulates the different pressures a physician applies to the pulse, thereby achieving accurate detection of different pulse patterns. The placement and structural design of the air inlet / outlet nozzles ensure smooth gas flow, guaranteeing the accuracy and stability of air pressure control.

[0039] The pressure detection nozzle 15, spaced apart from the air inlet and outlet nozzles, penetrates the single-layer flexible membrane and communicates with the inner cavity of the air bladder, serving as a connection to the pressure sensor. This spaced arrangement prevents gas flow from the air inlet and outlet nozzles from interfering with pressure detection, ensuring the pressure sensor can accurately measure pressure changes within the air bladder. The communication between the pressure detection nozzle and the air bladder's inner cavity allows the pressure sensor to acquire real-time pressure information from within the air bladder, providing accurate data support for the pulse diagnosis device and thus improving the accuracy and reliability of pulse diagnosis.

[0040] In summary, the various technical features of the airbag in this wristband-type TCM pulse diagnosis instrument work together to achieve high airtightness, stability, reasonable circuit layout, and accurate air pressure control and detection functions, providing strong support for the objectification and standardization of TCM pulse diagnosis.

[0041] Further preferably, the air inlet / outlet nozzle 14 extends 3-6 mm, preferably 5 mm, into the inner cavity of the airbag; the pressure detection nozzle 15 extends 5-10 mm, preferably 8 mm. This avoids membrane adhesion affecting its use and ensures smooth and accurate gas flow and pressure detection.

[0042] Further preferably, the inlet / outlet nozzles and pressure detection nozzles are provided with inlet / outlet clearance grooves 16 within the inner cavity of the airbag. This prevents the inlet / outlet nozzles and pressure detection nozzles from being squeezed when they are in contact with the wrist, ensuring that gas flow and pressure detection are unobstructed and improving the accuracy of pulse diagnosis.

[0043] More preferably, the intake and exhaust clearance grooves are provided with N grooves along the circumferential direction, where N is greater than or equal to 2.

[0044] Preferably, the centerlines of the air inlet / outlet nozzles and the pressure detection nozzle are perpendicular to the horizontal centerline of the airbag. This allows for precise control of the gas flow direction and pressure detection orientation, reducing interference and significantly improving the accuracy and reliability of pulse diagnosis data.

[0045] More preferably, the inlet and outlet nozzles have a diameter of 4-7 mm, an inner diameter of 2-3 mm, and a height of 3-6 mm; preferably, the outer diameter is 6 mm, the inner diameter is 2 mm, and the height is 5 mm; the pressure detection nozzle has an outer diameter of 4-7 mm, an inner diameter of 2-3 mm, and a height of 5-10 mm; preferably, the pressure detection nozzle has an outer diameter of 6 mm, an inner diameter of 2 mm, and a height of 8 mm; this ensures sufficient gas flow and pressure sensing sensitivity while also maintaining structural stability.

[0046] More preferably, the distance between the cable channel and the center line connecting the inlet / outlet nozzle and the pressure detection nozzle is 6-15mm, preferably 11mm. This avoids interference between the cable and the gas channel and detection components, ensures stable signal transmission, and improves the accuracy and reliability of the pulse diagnostic instrument.

[0047] Further preferably, the width of the cable routing channel is 0.1-2mm, with 0.2mm being the preferred width. This ensures smooth cable laying, avoids damage from excessive bending, effectively utilizes the internal space of the airbag, reduces interference between different cables, and guarantees stable signal transmission.

[0048] Further preferably, the wiring channel in the overlapping and sealed heat-sealed area is provided with an insulating isolation layer 17. This layer is made of a material with good insulation properties and flexibility (such as PVC film). The technical effects are: effectively isolating the wiring within the wiring channel, preventing short circuits or signal interference between lines, while maintaining the channel's flexibility and sealing, ensuring stable signal transmission, and improving the measurement accuracy and reliability of the pulse diagnostic instrument.

[0049] More preferably, the flexible membrane is made of PVC material, and the thickness of a single layer of flexible membrane is 0.1-0.5mm; preferably, 0.3mm; and the outer surface of the flexible membrane is smooth and flat, and at least the inner surface of the heat-sealed edge of the flexible membrane has concave and convex diagonal textures, and the convex design of the inner surface is conducive to heat-sealing connection.

[0050] In summary, the airbag designed in this utility model has the advantages of good sealing performance, structural stability, and effectively solves the problem of messy wiring harnesses.

[0051] The above description is only a preferred embodiment of the present utility model and is 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.
