Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a biofeedback therapy external display device. Background Technology

[0002] Generally, biosignals are divided into two categories: electrical signals, such as electrocardiograms (ECG), electroencephalograms (EEG), electromyograms (EMG), and cellular electrical activity; and non-electrical signals, such as body temperature, blood pressure, pH levels, and respiration. EMG signals are the most widely used of these signal sources and are easier to obtain. EMG signals are generated in any tissue or organ and are a type of bioelectrical signal that accompanies muscle contraction. They are a function of a waveform whose amplitude and frequency change over time.

[0003] Currently, biofeedback therapy devices typically integrate a display directly into the device. Biosignals are displayed on the screen in real time as threshold values ​​for medical staff to observe. Because biofeedback therapy devices require power and stable communication, users are often advised to remain as still as possible during use. However, due to the limited screen size, the displayed information can only be clearly seen at close range. This means that during some surgical procedures, doctors, due to their position or operating angle, cannot directly monitor the biosignals in real time and must ask nurses for assistance. This compromises timeliness and accuracy of communication. In some applications, patients need to view the biosignals themselves, but this is sometimes difficult to achieve while simultaneously operating the device. Utility Model Content

[0004] This invention provides a biofeedback therapy external display device, which helps to solve the problem that some existing biofeedback therapy instruments have limited display screen size, making it difficult to conveniently observe biosignals in real time in some work scenarios.

[0005] This utility model is implemented as follows:

[0006] A biofeedback therapy external display device includes a support structure with a fixed component and a movable component. The movable component is longitudinally adjustable relative to the fixed component. A bracket is movably connected to the top of the movable component. The bracket and the movable component are provided with a rotation adjustment structure. A panel is provided on the top of the bracket. A detachable projector is connected to the bottom of the bracket. The bracket can drive the projector to rotate around the longitudinal axis of the support structure. The projector is communicatively connected to a biofeedback therapy device via a cable. A groove for accommodating the cable is provided on the side wall of the support structure, and an anti-detachment structure is provided at the outer opening of the groove.

[0007] Based on the above technical solution, the fixed component and the movable component of the support structure are respectively a fixed rod and a movable rod, with the bottom of the movable rod sleeved on the top of the fixed rod, and a first locking structure is provided on the side wall of the area where the movable rod and the fixed rod are sleeved.

[0008] Based on the above technical solution, the bottom of the bracket is provided with a sleeve, which is sleeved on the top of the movable rod, and a second locking structure is provided on the side wall of the area where the sleeve and the movable rod are sleeved.

[0009] Based on the above technical solution, an I-beam frame is provided at the top of the sleeve. The I-beam frame is inclined and has several connecting holes. The panel and the projector are connected to the I-beam frame through the connecting holes and fasteners, respectively.

[0010] Based on the above technical solution, the top of the projector is provided with a track groove. The track groove has an inverted "T" shape. An installation bolt is installed in the track groove. One end of the installation bolt is engaged with the track groove, and the other end passes through the connecting hole and is locked with a nut. When the installation bolt is not locked, it can slide along the track groove to form an adjustable installation position structure for the projector.

[0011] Based on the above technical solution, the long side of the settling tank is set vertically, and the anti-detachment structure adopts an anti-detachment spring. One end of the anti-detachment spring is provided with a fixing part that is fixedly connected to the outer wall of the support structure, and the other end of the anti-detachment spring is provided with a flange that is bent radially outward relative to the support structure. The flange is also provided with an abutment part that can be radially recessed and abut against the outer wall of the support structure.

[0012] Based on the above technical solution, the long side of the settling tank is vertically arranged, and the anti-detachment structure adopts an anti-detachment clip. The anti-detachment clip is composed of two elastic plates that are staggered left and right. One end of the elastic plate is connected and fixed to the left and right side walls of the settling tank, and the other end forms a stacked partition structure.

[0013] Based on the above technical solution, a pressure block is provided in the settling tank. The pressure block is made of elastic material and has a groove on its inner end. The left and right sides of the pressure block elastically abut against the left and right side walls of the settling tank.

[0014] Based on the above technical solution, a tension spring is fitted on the mounting bolt, and the two ends of the tension spring abut against the I-beam and the projector respectively in the extension and contraction direction.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This invention features a support structure with a bracket mounted on it. The bracket houses the projector and panel. Furthermore, the projector's projection direction can be adjusted vertically and flexibly via a lifting and lowering adjustment mechanism on the support structure and a rotation adjustment mechanism between the support structure and the bracket. It communicates with a biofeedback therapy device via a cable, enabling real-time projection of biosignals onto a suitable location. This addresses the problem of limited screen size in some existing biofeedback therapy devices, making real-time observation of biosignals difficult in certain work scenarios.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1: Combination Figure 1-4This embodiment discloses a biofeedback therapy external display device, including a support structure, a bracket 4, a panel 5, and a projector 6. The projector 6 is connected to the biofeedback therapy device via a cable 7 (HDM I cable), so that the biosignals on the biofeedback therapy device can be transferred and projected through the projector 6, so as to achieve the effect of flexible and clear signal presentation position.

[0033] The support structure includes 83 fixed parts and movable parts, the movable parts being capable of longitudinal position adjustment relative to the 83 fixed parts. In this embodiment, combined with... Figure 1 As shown, the fixed part 83 and the movable part of the support structure respectively adopt a fixed rod 1 and a movable rod 3. The movable rod 3 has an inner hole at its bottom. The movable rod 3 is sleeved on the top of the fixed rod 1 through the inner hole. The relative longitudinal position of the fixed rod 1 and the movable rod 3 is controlled according to the sleeve depth. That is to say, the installation height of the support structure is controlled by the sleeve position between the fixed rod 1 and the movable rod 3, thereby achieving the height adjustment effect. In order to achieve stepless flexible control, a first locking structure a is provided on the side wall of the sleeve area of ​​the movable rod 3 and the fixed rod 1. The first locking structure a specifically includes a locking threaded through hole provided on the movable rod 3 and a locking bolt. After the locking bolt passes through the locking threaded through hole and is locked, its inner end abuts against the side wall of the fixed rod 1, forming a limiting constraint structure. The number of locking bolts and locking threaded through holes can be designed and processed according to actual needs.

[0034] Furthermore, the bottom of the bracket 4 is provided with a sleeve 41, which is sleeved on the top of the movable rod 3. A second locking structure b is provided on the side wall of the area where the sleeve 41 and the movable rod 3 are sleeved. The second locking mechanism serves as a rotation adjustment structure between the bracket 4 and the movable component. The second locking structure b has the same specific structure as the first locking structure a, except that the first locking structure a is used to control the height adjustment of the support structure, while the second locking structure b is used to control the relative angle orientation between the bracket 4 and the support structure. When the bracket 4 is not locked, it can drive the projector 6 to rotate and adjust around the longitudinal axis of the support structure.

[0035] The top of the bracket 4 has a panel 5, and the bottom of the bracket 4 is connected to a detachable projector 6. Combined Figure 2 As shown, the top of the sleeve 41 is provided with an I-beam frame 42, which is inclined and has several connecting holes 43. The panel 5 and the projector 6 are connected to the I-beam frame 42 through the connecting holes 43 and fasteners (bolts).

[0036] Furthermore, the top of the projector 6 is provided with two left-right oriented track grooves 61. The outline of the track grooves 61 is an inverted "T" shape. The track grooves 61 are fitted with mounting bolts 62. One end of the mounting bolt 62 is engaged with the track groove 61, and the other end passes through the connecting hole 43 and is locked with a nut. When the mounting bolt 62 is not locked, it can slide along the track groove 61, forming an installation position adjustment structure for the projector 6. This allows the projector 6 to be finely adjusted in lateral position on the bracket 4.

[0037] In actual use, the top of panel 5 is used to place medical supplies, such as medication details, operating instructions, gauze, scalpels, surgical forceps, etc.

[0038] To ensure a more stable and reliable supporting structure that prevents it from easily tipping over, a base 2 is provided at the bottom of the fixing rod 1. The base 2 has a frustum-shaped structure, and a counterweight platform 21 is also provided at the bottom of the base 2 to lower the center of gravity of the supporting structure and improve structural stability. The counterweight platform 21 uses a water-filled counterweight structure. This structure allows the entire external display device to be moved according to the actual needs of the scenario and remain stationary during use, so as to project biosignals to the appropriate location, facilitating real-time and convenient observation by doctors and other personnel in surgical and other situations.

[0039] Since the cable 7 is used for connection, in order to avoid the cable 7 being messy and causing unnecessary trouble to the working environment, the side wall of the support structure is provided with a sink 31 to accommodate the cable 7. The outer opening of the sink 31 is provided with an anti-drop structure to store and organize the cable 7 and avoid the hidden dangers of being tripped or tangled by the cable 7.

[0040] In this embodiment, the sink trough 31 is vertically arranged along its long side, and the anti-detachment structure uses an anti-detachment spring 8 made of aluminum alloy, combined with... Figure 3 and Figure 4 One end of the anti-detachment spring 8 is provided with a fixing part 83 that is fixedly connected to the outer wall of the support structure, and the other end of the anti-detachment spring 8 is provided with a flange 81 that is bent radially outward relative to the support structure. The function of the flange 81 is to facilitate the insertion of the outer cable 7 into the recess 31. The flange 81 is also provided with an abutment part 82 that can be radially recessed to abut against the outer wall of the support structure. The function of the abutment part 82 is to improve the sealing between the anti-detachment spring 8 and the support structure and reduce the occurrence of the inner cable 7 falling off.

[0041] In a specific embodiment, combined with Figure 9As shown, in this embodiment, the biofeedback therapy external display device is connected to the biofeedback therapy instrument c via a cable. The operating end of the biofeedback therapy instrument c is connected to an air bag d and an air bladder e. During use, pressing the air bladder e injects gas into the air bag d. During this process, the biofeedback therapy instrument c can monitor the pressure in the air bag d, convert it into an electronic signal, and display it digitally. Finally, the pressure value is projected onto the target location using the projector 6 in the biofeedback therapy external display device, making it convenient for medical staff or patients to observe. In other implementation scenarios, other biosignal indicators can also be displayed.

[0042] Example 2: Based on Example 1, combined with Figure 5 As shown, in this embodiment, the long side of the sink 31 is vertically oriented. The anti-detachment structure uses an anti-detachment clip 8t, which consists of two elastic pieces offset from left to right. The elastic pieces are made of aluminum alloy. One end of the elastic piece is connected and fixed to the left and right side walls of the sink 31, and the other end forms a stacked partition structure. This stacked partition structure can be appropriately misaligned under pressure, allowing the cable 7 to enter and exit the sink 31. Compared to the structure in Embodiment 1, the anti-detachment structure in this embodiment is built into the sink 31, which can prevent the structure from being exposed and causing snagging on clothing or accidental skin scratches.

[0043] Example 3: Based on Example 2, such as Figure 4 and Figure 5 As shown in this embodiment, in order to further improve the orderliness of the cable 7, a pressure block 9 is provided in the sink 31. The pressure block 9 is made of elastic material (rubber). The inner end of the pressure block 9 is provided with a slot 91. The slot 91 is used to constrain the cable 7 in the sink 31, so that the cable 7 can maintain a stable posture in the sink 31 as much as possible and will not be easily bent and exposed. After installation, the left and right sides of the pressure block 9 elastically abut against the left and right side walls of the sink 31.

[0044] Example 4: Based on Example 1, combined with Figure 6 As shown in this embodiment, a tension spring 63 is sleeved on the mounting bolt 62. The two ends of the tension spring 63 in the extension and retraction direction respectively abut against the I-beam frame 42 and the projector 6. Its function is to provide an elastic support force so that the projector 6 can be elastically constrained to keep its relative position still. When a lateral position fine adjustment is required, the mounting bolt 62 can slide in the track groove 61 by applying appropriate pressure to the tension spring 63. There is no need to loosen the nut on the mounting bolt 62, which makes the lateral position fine adjustment of the projector 6 more convenient and practical.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
