Foot stool for electrocardiogram equipment

Abstract

The invention belongs to the technical field of foot stools of electrocardiogram equipment, and particularly relates to a foot stool for electrocardiogram equipment, which comprises an electrocardiogram machine, supporting legs and a grip convenient to carry by hand. A medical worker carries the electrocardiograph by holding the grip. When the foot stool reaches a designated position, the downward pressing action of the trigger driving lever can be completed only by slightly expanding fingers, so that the trigger driving lever drives the trapezoidal frames at the tail ends of the two sides, when one side of each trapezoidal frame is pulled, the tight clamping force of the groove in the inner side of each trapezoidal frame is damaged, and the foot stool I and the foot stool II can be directly overturned only by slightly swinging; and the upper support arm and the lower support arm are driven to turn over at the same time during turning over. A medical worker slowly loosens a hand, so that the electrocardiograph is pressed down by virtue of the gravity of the electrocardiograph, and the diagonal bracket transmits the gravity to the hasp by clamping the hasp at the tail end of the diagonal bracket. The first foot stool and the second foot stool are shifted to rotate to the tail end of the stroke and then clamped by the stop lever, and bottom supporting can be completed.

Description

Technical Field

[0001] This invention relates to the field of electrocardiogram (ECG) equipment tripod technology, specifically to an ECG equipment tripod. Background Technology

[0002] The core function of a tripod for an electrocardiogram (ECG) device is to support the main unit and optimize workflow. It typically features a metal frame design with casters at the bottom for easy movement and a top tray for stable placement of the ECG main unit.

[0003] Existing technologies have the following shortcomings: Currently, the tripods widely used in clinical practice for electrocardiogram (ECG) equipment mostly employ rigid metal frame structures. While these structures can stably support the main unit, their design function is limited: they only meet the static usage needs within hospital wards. When facing pre-hospital emergency scenarios (such as ambulance transport or emergency care at traffic accident scenes), traditional tripods reveal significant deficiencies—their fixed bases are bulky and difficult to adapt to the confined spaces of vehicles; they lack a quick deployment / retraction mechanism, unnecessarily increasing operational time in time-sensitive emergency situations. Although the support strength of these tripods meets hospital standards, their excessive weight (generally exceeding 15kg) and non-foldable structure greatly limit their practicality in mobile emergency scenarios, forcing medical personnel to abandon tripods and instead risk placing the equipment directly on unstable surfaces (such as the edge of a stretcher), which affects detection accuracy and increases the risk of the equipment falling. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tripod for electrocardiogram (ECG) equipment, which solves the problem that current tripod structures are too bulky and heavy, making them inconvenient for temporary emergency care.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tripod for an electrocardiogram (ECG) device, comprising an ECG machine, a support leg, and a handle for easy carrying. An upper support arm and a lower support arm are provided below the support leg, so that the upper and lower support arms serve as the main support structures. A first tripod and a second tripod are rotatably provided on the side end of the lower support arm to increase the support surface, so that the ECG machine can be stably supported and used.

[0006] The support foot has a through-slot groove on both sides, and a diagonal bracket is rotatably installed inside the groove to provide stable support for the electrocardiograph.

[0007] A buckle is inserted laterally inside the upper arm.

[0008] In some embodiments, the support arm is rotatably connected to the side end of the support foot, and the side end of the upper support arm is provided with a limiting plate to prevent its rotation angle from being too large.

[0009] In some embodiments, a strip-shaped through slot is provided between the grip and the electrocardiograph for accommodating the insertion of a finger.

[0010] In some embodiments, a shaft is provided at the end of the diagonal bracket on one side of the contact support foot. The shaft passes through both sides of the slide groove. This design allows the diagonal bracket to rotate via the shaft and also move horizontally along the slide groove via the shaft.

[0011] In some embodiments, the first leg is designed as a single-sided single-strut, and the second leg is designed as a single-sided parallel double-strut structure.

[0012] Both the first and second legs are rotatably connected to the side of the lower support arm via a horizontal shaft.

[0013] In some embodiments, a stop bar is horizontally connected to the middle of the lower support arm to block the rotational travel of the first and second tripods. A stop buckle is provided on the outer side of the second tripod that contacts the horizontal axis. The stop buckle is restricted by the stop bar during the rotation of the second tripod and stops at the maximum support angle.

[0014] In some embodiments, the lower support arm is rotatably connected to the end of the upper support arm. The end of the upper support arm is provided with a shaft, and the end of the lower support arm is provided with a collar. When the collar is sleeved on the outside of the shaft, the upper support arm and the lower support arm can have a preliminary rotatable connection.

[0015] The collar has three sets of annular grooves inside, and a latch is provided on the side end of the collar. The latch is provided with a plate on its side end.

[0016] In some embodiments, the latch passes through an annular groove via a insert plate and is fixedly connected to the insert shaft after passing through the annular groove.

[0017] In some embodiments, a protective plate is provided between the upper and lower support arms to enhance the rigidity of the overall structure. The protective plate can also provide rear protection for the electrocardiograph after the overall structure is stowed away.

[0018] In some embodiments, the electrocardiograph is provided with a trapezoidal frame at the top, and a groove is provided in the middle of the trapezoidal frame so that the first and second legs can be inserted into the groove. A trigger lever is provided on the side of the trapezoidal frame and passes through the handle.

[0019] Compared with the prior art, the present invention provides a tripod for an electrocardiogram (ECG) device:

[0020] An electrocardiogram (ECG) device tripod is disclosed, allowing medical personnel to carry the ECG machine by gripping the handle. Upon reaching the designated position, a slight expansion of the fingers depresses the trigger lever, causing it to actuate the trapezoidal frames at both ends. Pulling one side of the trapezoidal frame breaks the tight clamping force of its inner grooves, allowing tripods one and two to flip directly with a slight wiggle. This flip also causes the upper and lower support arms to flip simultaneously. The medical personnel slowly release their grip, allowing the ECG machine to press down under its own weight, and then lock the diagonal support ends into latches to transmit weight. Rotating tripods one and two to their final stroke position, where they are then locked by a stop bar, provides bottom support.

[0021] Through the above settings and processes, this structure achieves the following beneficial effects:

[0022] 1. Quick and easy to use: The tripod structure is integrated with the ECG equipment, so there is no need to carry an extra tripod when the ECG equipment needs to be moved quickly and temporarily, making it fast and convenient.

[0023] 2. The overall structure is compact through integrated design. When used normally at the hospital bedside, its integrated stand can be folded to provide additional external protection for the electrocardiograph machine, and its presence is low and does not affect normal use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Please see Figure 1-9 In this embodiment: a tripod for an electrocardiogram (ECG) device includes an ECG machine 1, a support leg 2, and a handle 3 for easy carrying. An upper support arm 4 and a lower support arm 5 are provided below the support leg 2, so that the upper support arm 4 and the lower support arm 5 serve as the main support structure. A first tripod 15 and a second tripod 16 are rotatably provided on the side of the lower support arm 5 to increase the support surface, so that the ECG machine 1 can be stably supported and used.

[0038] The upper support arm 4 is rotatably connected to the side end of the support leg 2 (e.g.) Figure 3As shown, a limiting plate 8 is set on the side of the upper arm 4 to prevent its rotation angle from being too large. In this way, the rotation path is automatically blocked after the upper arm 4 rotates to the appropriate angle.

[0039] A strip-shaped through groove is provided between the handle 3 and the electrocardiograph 1. This through groove can accommodate the fingers of medical staff to make it easy to hold the handle 3.

[0040] Since the weight of the ECG machine 1 cannot be evenly distributed by the upper support arm 4 contacting only one end of the support leg 2, a through-slot 7 is opened on the side of the support leg 2. Inside this slot 7, a diagonal support 6 is rotatably mounted to provide stable support for the ECG machine 1. A shaft is positioned at the end of the diagonal support 6 that contacts the support leg 2, and this shaft passes through both sides of the slot 7 (e.g., ...). Figure 3 As shown), this design allows the diagonal bracket 6 to rotate via the shaft and also move horizontally along the slide groove 7 via the shaft. A latch 9 is inserted laterally inside the upper support arm 4. The latch 9 is used to limit the rotation of the diagonal bracket 6 and keep it stably supported. The other side of the diagonal bracket 6 has a concave semi-circular structure, and this structure is locked onto the outside of the latch 9, which provides support to that end (e.g., Figure 4 (As shown). Therefore, when the electrocardiograph 1 applies pressure to the support leg 2, the support leg 2 distributes the gravity to both ends, and the specific gravity transmission is as follows:

[0041] The gravity of the electrocardiograph 1 is transmitted downwards through the upper support arm 4;

[0042] The gravity of the electrocardiograph 1 is transmitted to the buckle 9 through the diagonal support 6 on the other side, and the diagonal support 6 is pressed tightly against the buckle 9.

[0043] Since the pressure of the ECG machine 1 is concentrated at the buckle 9 after being dispersed, in order to achieve the stability of the overall structure, the upper support arm 4 and the lower support arm 5 are tilted towards the ECG machine 1 as a center of gravity compensation for the main support, and the tripod 15 and tripod 2 16 are differentiated, the specific differentiated design of which is as follows:

[0044] The first tripod 15 adopts a single-sided single-strut design and is longer than the second tripod 16. This makes the distance between the ground landing point of the first tripod 15 and the end of the lower support arm 5 longer than that distance of the second tripod 16. As a result, the support area on the side where the center of gravity of the electrocardiograph 1 is offset is larger, which can provide further compensation for the center of gravity offset to improve stability.

[0045] The tripod 2.16 adopts a single-sided parallel double-bar structure design (such as...). Figure 6 (As shown), to disperse the transmission of gravity.

[0046] Both tripod 15 and tripod 2 16 are rotatably connected to the side end of the lower support arm 5 via a horizontal axis (e.g. Figure 6As shown), therefore, tripod 15 and tripod 2 16 can rotate around this axis. To ensure that their rotation angle is not too large, a stop bar 17 is horizontally connected in the middle of the lower support arm 5 to block the rotation stroke of tripod 15 and tripod 2 16 (as shown). Figure 8 As shown), since the first leg 15 passes through the middle of the lower support arm 5, it will be stopped by the stop bar 17 at the end of its rotation stroke. Since the second leg 16 does not pass through the middle of the lower support arm 5, a stop 18 is provided on its outer side that contacts the horizontal axis to achieve the same limiting effect. Figure 8 As shown), the stop 18 is restricted by the stop lever 17 during the rotation of the second tripod 16, and stops at the maximum support angle (as shown). Figure 6 (The opening angle shown).

[0047] The lower support arm 5 is rotatably connected to the end of the upper support arm 4. To ensure that the upper support arm 4 and the lower support arm 5 can provide stable support while also being foldable for storage, a shaft 10 is provided at the end of the upper support arm 4, and a collar 11 is provided at the end of the lower support arm 5. When the collar 11 is fitted onto the outside of the shaft 10, it allows the upper support arm 4 and the lower support arm 5 to have a preliminary rotatable connection. Three sets of annular grooves 12 are formed inside the collar 11 (e.g., Figure 7 (As shown), and a latch 13 is provided on the side end of the collar 11, and an insert plate 14 is provided on the side end of the latch 13. The specific assembly method is as follows:

[0048] The latch 13 passes through the annular groove 12 via the insert plate 14 and is fixedly connected to the insert shaft 10 after passing through the annular groove 12. This arrangement limits the rotation range of the insert shaft 10 and the latch 13 to the inside of the annular groove 12.

[0049] By limiting the rotation range of the insert shaft 10 and the latch 13, the upper support arm 4 and the lower support arm 5 are kept in a supported state (e.g., Figure 5 (as shown in the state) At this time, due to the tilt of the upper support arm 4 and the lower support arm 5 and the pressure applied by the electrocardiograph 1, the insertion plate 14 is pressed tightly against the end of one side of the annular groove 12. Since it is at the end of the one-way stroke of the insertion plate 14, the upper support arm 4 and the lower support arm 5 will not rotate beyond this angle. Thus, the maximum support angle of the upper support arm 4 and the lower support arm 5 is limited, and it also has the effect of rotating in the opposite direction to fold.

[0050] A protective plate 19 is provided between the upper support arm 4 and the lower support arm 5 on both sides to enhance the rigidity of the overall structure. The protective plate 19 can also be installed after the overall structure is stored (e.g., Figure 2 (As shown in the diagram) provides rear protection for ECG machine 1.

[0051] A trapezoidal frame 21 is provided at the upper end of the electrocardiograph 1. A groove is provided in the middle of the trapezoidal frame 21, which allows the first tripod 15 and the second tripod 16 to be inserted, thus ensuring that the first tripod 15 and the second tripod 16 are neatly stored in their folded state. The trapezoidal frame 21 is made of plastic, and a trigger lever 22 is provided on its side end. The trigger lever 22 passes through the handle 3 and is positioned horizontally below the handle 3 (e.g., ...). Figure 9 As shown), when the operator holds the handle 3, he only needs to slightly expand his fingers to complete the downward action of the trigger lever 22, so that the trigger lever 22 drives the trapezoidal frame 21 at both ends. When one side of the trapezoidal frame 21 is pulled, the tight clamping force of its inner groove is broken, and the first leg 15 and the second leg 16 can be directly flipped with only a slight swing.

[0052] In this embodiment, medical personnel carry the electrocardiograph 1 by holding the handle 3. Upon reaching the designated position, a slight expansion of the fingers is sufficient to press down the trigger lever 22, causing it to move the trapezoidal frames 21 at both ends. When one side of the trapezoidal frame 21 is pulled, the tight clamping force of its inner groove is broken, allowing the first and second legs 15 and 16 to flip directly with only a slight sway. This flip also causes the upper arm 4 and lower arm 5 to flip simultaneously. The medical personnel slowly release their grip, allowing the electrocardiograph 1 to press down under its own weight, and by locking the ends of the diagonal brackets 6 into the latches 9, the weight of the diagonal brackets 6 is transmitted to the latches 9. Rotating the first and second legs 15 to their end of their travel and then locking them in place by the stop lever 17 completes the bottom support.

[0053] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
