Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a fixing assembly and an anesthesia device. Background Art

[0002] At present, weighing sensors are used in anesthesia devices to detect the weight of absorption tanks. The detection accuracy of weighing sensors depends on the deformation of the sensor itself. The deformation is converted into changes in electrical signals to achieve weight detection of the absorption tank above it.

[0003] The existing weighing sensors are fixed between adjacent components, and the force transmission from the adjacent components causes the sensor itself to deform. Force transmission is usually achieved by setting up stacked sheets or protruding structures on adjacent components to offset each other. No matter which method is used, the contact position and contact area between the weighing sensor and the adjacent components cannot be accurately controlled, and the deformation amount caused by the force is inaccurate, which cannot meet the requirements of the anesthesia device for weighing accuracy.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0036] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention.

Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0038] like Figures 1 to 4 As shown, in the first aspect, an embodiment of the present application provides a fixing assembly, which is applied to fix a weighing sensor 10. The weighing sensor 10 includes a first fixing section 11, a deformable connecting section 12, and a second fixing section 13 arranged in sequence. The fixing assembly includes: a mounting plate 20 and a transition structure 40, wherein:

[0039] The mounting plate body 20 is provided with a first connecting portion 21 and a first rigid connecting member 22 which are fixedly connected, and the first fixing section 11 is abutted against the first rigid connecting member 22 via a first fastener 31;

[0040] The transition structure 40 is provided with a second connecting portion 41 and a second rigid connecting member 42 which are fixedly connected. The side of the second fixing section 13 away from the first fastening member 31 abuts against the second rigid connecting member 42 through the second fastening member 32 .

[0041] The first rigid connecting piece 22 and the second rigid connecting piece 42 are respectively abutted against the weighing sensor 10, realizing the rigid fixation of the weighing sensor 10, and transmitting all the forces generated by the weight change of the load during the weighing process to the weighing sensor 10, thereby meeting the requirement of accurate measurement of weight change in the anesthesia device. At the same time, the setting of the rigid connecting piece can also meet the control of the effective contact area between it and the weighing sensor 10, thereby effectively solving the problem in the prior art that the contact area cannot be controlled, resulting in errors in the actual measurement accuracy of the weighing sensor.

[0042] It can be understood that the more concentrated the force acting received by the weighing sensor is, the more obvious the force acting effect is, and the better the measurement accuracy is. In the traditional fixing scheme, simple laminations are used for abutting. The accuracy control of the stacked sheets is poor, and it is not conducive to installation. Deviations generated during the assembly process will affect the actual effective area of force transmission, and the measurement accuracy cannot be unified. And the method of stamping convex bumps on the metal part to form a structure abutting against the weighing sensor cannot control the height and shape of the convex bumps, the position of the contact point in the vertical direction is uncertain, and the contact area cannot be controlled. However, the technical solution in the embodiment of the present application uses a rigid connecting piece with a fixed connection, which can control the processing accuracy, does not require laminations, has strong controllability, high accuracy control, and strong consistency after assembly, and is more conducive to high-precision weighing requirements.

[0043] As Figures 5 to 8 shown, in some embodiments of the present application, the first rigid connecting piece 22 and the second rigid connecting piece 42 are annular washers. The first fastener 31 is passed through the first rigid connecting piece 22, and the second fastener 32 is passed through the second rigid connecting piece 42. The setting of the annular washer can be adapted to the fastener, is convenient for assembly, and a circumferential limit is formed between its inner ring and the fastener, and the assembly accuracy is higher.

[0044] Furthermore, the inner ring of the annular washer can be provided with a structure adapted to the fastener, such as thread fit, snap fit, bevel fit, etc. Through different fitting methods, the fitting position between the two can be accurately controlled, the structure is more compact, and at the same time the assembly performance is better, which is more conducive to subsequent assembly.

[0045] As Figure 5 and Figure 7 shown, in some embodiments of the present application, the first rigid connecting piece 22 and the second rigid connecting piece 42 are metal washers in a circular ring shape. The circular ring-shaped washer is more conducive to processing and assembly, has better adaptability, and at the same time the shape of the circular ring can improve the circumferential structural strength of the washer, meeting the strength requirements for the rigid connecting piece. The washer made of metal material has high structural strength, and has high wear resistance and processability. The specific material can be chromium-containing alloy material, spring steel material, stainless steel alloy, aluminum alloy, etc.

[0046] It should be noted that in some alternative embodiments, the first rigid connecting member 22 and the second rigid connecting member 42 can be made of high-strength and high-wear-resistant non-metallic materials, such as carbon fiber materials, wear-resistant ceramic materials, polytetrafluoroethylene, etc.

[0047] In some embodiments of the present application (not shown in the figure), the first rigid connecting member 22 is fixedly welded to the first connecting portion 21; and / or, the second rigid connecting member 42 is fixedly welded to the second connecting portion 41. The welding fixing method can provide higher connection strength than riveting, bolt connection, and adhesive connection. Welding also has the advantages of high precision, versatility, cost-effectiveness, speed, flexibility, aesthetics, durability, and low maintenance. At the same time, the processing requirements for the first rigid connecting member 22 and the first connecting portion 21, as well as the second rigid connecting member 42 and the second connecting portion 41, are relatively low, and the economic benefits are better. It should be noted that when fixed by welding, the first rigid connecting member 22 and the first connecting portion 21, and / or the second rigid connecting member 42 and the second connecting portion 41 do not need to use the same materials, as long as the welding conditions can be met.

[0048] Furthermore, as Figure 6 and Figure 8 shown, in some embodiments of the present application, both the first connecting portion 21 and the second connecting portion 41 are circular through holes, and the diameter of the first connecting portion 21 is smaller than the inner diameter of the first rigid connecting member 22, and the diameter of the second connecting portion 41 is smaller than the inner diameter of the second rigid connecting member 42. Such a setting can satisfy welding at the positions of the inner and outer circles of the first rigid connecting member 22 and the second rigid connecting member 42 respectively. Such a setting makes the structural stability of the first rigid connecting member 22 and the second rigid connecting member 42 better after being fixed. At the same time, the welding position can be selected. When welding the inner and outer circles simultaneously, the internal structural stress generated by welding can be offset, improving the welding precision and the structural stability.

[0049] As Figures 2 to 8 shown, in some embodiments of the present application, the first connecting portion 21, the first rigid connecting member 22, the second connecting portion 41, and the second rigid connecting member 42 are provided in multiple numbers, and the corresponding first fasteners 31 and second fasteners 32 are provided in multiple numbers. The above setting is used to increase the contact points of the force action. For the first connecting portion 21 and the first rigid connecting member 22, increasing multiple contact points can better fix the weighing sensor 10, increase the structural stability during its installation, and at the same time, when dealing with the application of force, disperse it to multiple points to avoid the situation of force concentration between the weighing sensor 10 and the fixing failure.

[0050] As for the second connecting portion 41 and the second rigid connecting member 42, adding multiple contact points can also avoid the situation where force is concentrated and cause fixation failure. At the same time, it can also disperse the position where force acts when force is applied and reduce the torque, so that the force of the entire second fixed section 13 is more uniform and stable, and the deformation effect is more accurate, thereby making the measurement accuracy more accurate.

[0051] It should be noted that, in an optional embodiment, the first connecting portion 21 and the first rigid connecting member 22 and the corresponding second connecting portion 41 and the second rigid connecting member 42 are centrally symmetrically arranged. Such an arrangement has the same size and opposite direction of the installed components and the force points, and can concentrate the force on the middle deformable connecting section 12, thereby being more sensitive to changes in force and more accurate in detecting force.

[0052] Furthermore, if Figures 2 to 8 As shown, in some embodiments of the present application, each first connection part 21 and each second connection part 41 are sequentially arranged along the length direction of the weighing sensor 10. Such an arrangement enables the first connection part 21 and the second connection part 41 to be located in the same plane, and the force direction thereof is vertically upward, so that the deformation position generated by the force can be better controlled and the detection result can be accurately detected.

[0053] In an optional embodiment, each first connecting portion 21 and each second connecting portion 41 are located on the center line of the weighing sensor 10 in the width direction. Such a setting can better adapt to the structure of the weighing sensor 10, making its force position more accurate and the collected weight information more accurate and stable.

[0054] like Figure 2 As shown, in some embodiments of the present application, each first fastener 31 and each second fastener 32 are threaded fasteners, and are threadedly connected to the weighing sensor 10. The threaded connection assembly method can achieve tightness adjustment and self-locking, can provide fixed installation of the first rigid connector 22 and the second rigid connector 42, has a good assembly effect, and will not cause looseness and movement, provides rigid fixation of the entire weighing sensor 10, is conducive to accurate deformation detection, and thus accurate detection results.

[0055] It should be noted that a plurality of threaded connection holes are correspondingly provided on the weighing sensor 10 to facilitate the threaded connection of the fasteners.

[0056] Furthermore, Figure 4As shown, in an optional embodiment, the weighing sensor 10 is provided with four threaded through holes, which are arranged on the first fixing section 11 and the second fixing section 13 respectively. The first fixing section 11 is provided with an extension step on the side facing the mounting plate 20, and the corresponding second fixing section 13 is provided with an extension step on the side facing the adapter structure 40, so that the entire weighing sensor 10 generally presents an inverted "Z" shape. Such a setting increases the thickness of the first fixing section 11 and the second fixing section 13 in the vertical direction, which is conducive to increasing its structural strength and adapting to large weight changes. A hollow area is provided in the middle of the corresponding deformation connecting section 12, which is generally a circular area with two parts intersecting. The hollow area reduces the overall strength of the deformation area and can better adapt to deformation. At the same time, compared with the two fixed sections, the deformation connecting section 12 is thinner in the vertical direction, and the hollow area is more likely to deform. Such a setting is conducive to deformation concentration and higher detection accuracy. The weighing sensor 10 can be made of memory alloy.

[0057] like Figure 7 and Figure 8 As shown, in some embodiments of the present application, the mounting plate 20 is provided with an accommodation space 23, and the accommodation space 23 is provided corresponding to the deformable connecting section 12 and the second fixing section 13. Such a setting is used to make way for the deformable connecting section 12 and the second fixing section 13, so that the weight deformation that can be detected by the deformable connecting section 12 is amplified, thereby increasing the detection range.

[0058] It should be noted that the deformation of the deformable connecting section 12 is mainly affected by the pressure at the top noon, so the second fixed section 13 will move downward in the vertical direction, and the accommodating space 23 is used to accommodate the deformed part of the weighing sensor 10. Such a setting structure is compact and ingenious, which can increase the detection range. At the same time, the mounting plate 20 is easy to process, and the weight is reduced after the material is reduced, which is more conducive to lightweight.

[0059] Furthermore, in an optional embodiment, the accommodating space 23 is a through hole, and the projection of the accommodating space 23 in the vertical direction matches the projection gap of the second fixed section 13 and the deformable connecting section 12 in the vertical direction. Such a setting makes the accommodating space 23 more adaptable and the structural strength of the mounting plate body 20 higher.

[0060] like Figure 2 and Figure 3As shown, in some embodiments of the present application, the fixing assembly further includes an upper shell 50 and a weighing platform 60, the upper shell 50 is connected to the mounting plate 20, and the weighing platform 60 is provided with a plurality of sensor columns 61, each of which can movably pass through the upper shell 50 and be connected to the adapter structure 40. The upper shell 50 is provided to cover the various parts of the fixing assembly to prevent the intrusion of water vapor and dust from affecting the weighing sensor 10. The sensor column 61 is used to connect the adapter structure 40 to transfer the force to the adapter structure 40. The use of the sensor column 61 can control the point of force transmission so that it is concentrated on the adapter structure 40, and the force transmission effect is better.

[0061] Furthermore, if Figure 2 and Figure 3 As shown, in an optional embodiment, the upper shell 50 is provided with a plurality of assembly holes 51, and the sensing column 61 is correspondingly provided with a plurality of connection holes 43, and the connection holes 43 correspond to the sensing column 61, and the end of the sensing column 61 facing the upper shell 50 is provided with a threaded hole, and the threaded fastener passes through the connection hole and is threadedly connected with the threaded hole, so that the adapter structure 40 and the end of the sensing column 61 facing the upper shell 50 are tightly combined, and such a setting has better fixed connection, better force transmission effect, and stronger overall rigidity. There is a clearance fit between the assembly hole 51 and the sensing column 61, or an elastic seal is provided between the assembly hole 51 and the sensing column 61, and such a setting meets the sealing requirements and does not hinder force transmission.

[0062] It should be noted that if Figure 9 As shown, in an optional embodiment, the side of the weighing platform 60 away from the upper shell 50 can accommodate the placement of a tank 80, which can be a waste collection tank. In the anesthesia device, it absorbs waste gas to increase its own weight, thereby achieving weighing. At the bottom of the fixed component, that is, the side of the mounting plate 20 away from the weighing sensor 10, a sheet metal part 70 for connecting the anesthesia device system is also provided. The sheet metal part 70 is generally L-shaped, with the long side fixedly connected to the mounting plate 20 and the short side connected to the anesthesia device system.

[0063] In an optional embodiment, the fixing method of the fixing component is to weld a circular metal gasket (i.e., the second rigid connector 42) on the adapter structure 40, which can not only ensure that the force-bearing area of ​​the weighing sensor 10 is fixed, but also enhance the rigidity of the entire fixing component, so that the sampling of the weighing sensor 10 is more stable.

[0064] In the above optional embodiment, the fixing assembly is mainly composed of six parts, namely, the sheet metal part 70, the mounting plate 20, the upper shell 50, the adapter structure 40 and the weighing platform 60. The weighing sensor 10 is arranged between the mounting plate 20 and the adapter structure 40.

[0065] The short side of the sheet metal part 70 is connected to the system of the anesthesia device, and the long side is connected to the mounting plate 20;

[0066] Two circular metal gaskets (i.e., first rigid connectors 22) are welded on the mounting plate 20 and connected to the weighing sensor 10;

[0067] The upper housing 50 is fixedly provided with a circuit board structure, a wire outlet, and an assembly hole 51 for the sensor column 61 to move;

[0068] The weighing sensor 10 has four threaded holes in a Z-shaped shape after being rotated 90 degrees. The extended step of the first fixing section 11 is connected to the mounting plate 20, and the extended step of the second fixing section 13 is connected to the adapter structure 40.

[0069] A circular metal gasket (i.e., the second rigid connector 42) is welded on the adapter structure 40 and connected to the weighing sensor 10. The cross-sectional shape of the adapter structure 40 is like an inverted "X" shape.

[0070] Three sensor columns 61 are arranged on the weighing platform 60 and are respectively connected to the switching structure 40 . The side of the weighing platform 60 away from the sensor columns 61 is where the object to be weighed is placed and has no contact with the housing.

[0071] The working method of the weighing sensor 10 in the anesthesia device is as follows: the adapted tank body 80 is placed on the weighing platform 60. The tank body 80 is the absorption tank of the anesthesia device. After the absorption tank absorbs the exhaust gas, the overall mass increases. The corresponding deformation connecting section 12 of the weighing sensor 10 will undergo a certain deformation due to the increase in the mass of the weighed object. These deformations will be converted into electrical signals to output specific values. This value can be used to calculate the weight of the weighed object after a certain algorithm. Among them, the fixing system described in this patent is that after fixing the weighing sensor, the overall rigidity is sufficient to only allow the weighing sensor to deform, and the other parts will not deform or deform slightly, so that the value of the deformation of the weighing sensor after conversion is closer to the actual weight of the weighed object.

[0072] Circular metal gaskets are welded on the mounting plate 20 and the adapter structure 40 connected to the weighing sensor 10. This fixing component increases the rigidity of the weighing sensor 10 after it is fixed, making it less prone to deformation, so that the deformation amount is concentrated on the weighing sensor 10 itself, making the data measured by the weighing sensor 10 more stable and accurate.

[0073] In a second aspect, an embodiment of the present application provides an anesthesia device, the anesthesia device comprising a fixing assembly as in the above embodiment. The structure and function of the fixing assembly can be referred to in the above embodiment of the fixing assembly, and will not be described in detail here.

[0074] The anesthesia device can be an anesthesia machine, a veterinary anesthesia machine, etc., which can make the weight information collected by the weighing sensor more accurate and precise through the above-mentioned fixing components, so as to meet the precise requirements for weighing in medical scenarios such as surgeries.

[0075] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the utility model disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include well-known knowledge or conventional technical means in the technical field not disclosed in the present application.
