Description

Technical Field

[0001] This invention relates to the field of infusion management frame technology, specifically a mobile tiered infusion management frame for mass casualties. Background Technology

[0002] A mobile tiered infusion management stand is a medical device specifically designed for the emergency treatment of multiple casualties, enabling efficient and orderly management of intravenous infusion therapy for multiple patients. This device typically integrates a multi-channel infusion stand, a tiered labeling system, and mobile components to adapt to the rapid deployment needs of on-site rescue or hospital emergency departments. In cases of mass casualties, the workload increases dramatically, and staff may easily overlook whether the infusion has finished, making reminders essential. Failure to address the depletion of medication in a timely manner could lead to serious medical risks such as air embolism. However, in clinical practice, the likelihood of air embolism is relatively low. Air embolism typically stops once a certain pressure ratio is reached, and after it stops, tubing blockage can occur, causing the needle to become stuck.

[0003] A search revealed patent application number (202010479189.2), which discloses "A Multifunctional Infusion Stand," comprising a hook frame, a telescopic main support, and a support frame. The telescopic main support includes a first main column and a second main column, with the lower part of the second main column passing through and slidably connected to the first main column. The hook frame includes a hook post and a hook support, with the lower end of the hook post detachably connected to the upper end of the second main column. The upper end of the hook post is provided with a hanging hook, and the hook support is mounted on the hook post with multiple hooks. The support frame includes at least three evenly spaced support feet, the upper ends of which are rotatably connected to the lower ends of the first main column, and the lower ends of the support feet are provided with casters. Therefore, this invention has the advantages of meeting different height requirements, suspending various items, being a portable hook frame, easy to move, and having a small storage space.

[0004] However, the aforementioned devices have the following problems: Existing IV stands require patients or their families to constantly monitor the infusion process, and the difficulty of observation increases significantly due to variations in light and angle, potentially leading to air ingress after the infusion is complete. This not only places a continuous psychological burden on patients, especially elderly, children, or critically ill patients who are often physically exhausted or distracted, but also greatly increases the caregiving pressure on family members, requiring them to maintain high vigilance for extended periods. In nighttime infusion scenarios, dim lighting makes it even more difficult to observe the drip rate, and medical staff managing multiple patients simultaneously cannot conduct real-time monitoring. If the medication runs out without timely intervention, it could lead to serious medical risks such as air embolism, posing a potential threat to patient safety. Therefore, we propose a mobile, tiered IV management stand for mass casualties to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile graded infusion management frame for mass casualties, in order to solve the problem mentioned in the background art that patients or their families need to pay close attention to the infusion situation during infusion to avoid the injection of air after the infusion is completed, which poses a potential threat to the patient's life safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile triage infusion management frame for mass casualties, comprising an infusion frame, a handle connected to the outer side of the infusion frame, a placement frame movably connected to the top of the infusion frame, a reminder component provided at the bottom of the placement frame, and wheels connected to the bottom of the infusion frame. The reminder component includes a first rotating shaft, a movable groove, a steel wire rope, a guide wheel, a connecting frame, a proximity switch, and a torsion spring. The outer side of the placement frame is connected to a first rotating shaft, the inner end of the placement frame is connected to a steel wire rope, the inside of the infusion stand is provided with a movable groove, the inner wall of the movable groove is provided with a guide wheel, the other end of the steel wire rope is connected to a connecting frame, a proximity switch is installed at the bottom of the movable groove, and a torsion spring is sleeved on the outer side of the first rotating shaft.

[0007] Preferably, the top of the placement frame is provided with an indicator component, which includes a half gear, a second rotating shaft, a driven gear, and an indicator flag. The half gear is fixedly connected to the outer surface of the first rotating shaft, the top of the infusion stand is rotatably connected to the second rotating shaft, the center position of the second rotating shaft is fixedly connected to the driven gear, and the outer side of the driven gear is fixedly connected to the indicator flag.

[0008] Preferably, the bottom of the infusion stand is provided with a positioning component, which includes an external thread, a positioning ring and a tray. The outer surface of the bottom of the infusion stand is provided with an external thread, and the outer thread of the external thread is connected to the positioning ring. The bottom of the infusion stand is fixedly connected to the tray, and the inner diameter of the positioning ring is adapted to the diameter of the traveling wheel.

[0009] Preferably, an audible and visual alarm corresponding to the placement rack is fixedly installed on the surface of the infusion stand, and the bottom of the proximity switch is connected to the audible and visual alarm via a wire.

[0010] Preferably, an observation window is snapped onto the outer side of the movable groove, and the observation window is made of transparent material.

[0011] Preferably, weights are placed inside the connecting frame.

[0012] Preferably, a fixing frame is mounted on the surface of the positioning ring, and the number of fixing frames corresponds to the number of placement frames inside.

[0013] Preferably, the placement rack is distinguished by different colors, and the weights and indicator flags correspond to their colors.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of the reminder component, when the infusion bottle is suspended on the placement rack, the placement rack rotates around the first rotating axis. Through the "seesaw" principle, the steel wire rope is pulled along the guide wheel for transmission. When the infusion is nearing completion, as the amount of medicine decreases, the weight of the infusion bottle gradually decreases. Under the dual action of the torsion spring's reset force and the weight built into the connecting rack, the internal circuit is triggered to conduct, causing the corresponding audible and visual alarm to emit a high-decibel buzzer and flashing light.

[0015] 2. By setting up an indicator component, after the infusion is completed, the half gear drives the driven gear to rotate, so that the matching indicator flag changes from a horizontal, inverted state to a vertically upright state, forming a dual visual and auditory reminder mechanism, which makes it easy for staff to observe from a distance and ensures that patients, their families and medical staff can respond in a timely manner to the completion of the infusion.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Please see Figure 1-5 This invention provides an embodiment of a mobile triage infusion management frame for mass casualties, comprising an infusion frame 1, with a handle 2 connected to the outer side of the infusion frame 1. The infusion frame 1 consists of two parts connected by threads, which can be split in the middle for easy mounting on a mobile resuscitation bed, allowing it to move with the bed. It can also be connected to wheels 7 as a standalone infusion frame, usable in pre-hospital, in-hospital, and post-hospital emergency care, improving the applicability of the device. A placement frame 3 is movably connected to the top of the infusion frame 1, and a reminder component 4 is provided at the bottom of the placement frame 3. Wheels 7 are connected to the bottom of the infusion frame 1. The reminder component 4 includes a first rotating shaft 401, a movable groove 402, a steel wire rope 403, a guide wheel 404, a connecting frame 405, a proximity switch 407, and a torsion spring 408. The outer side of the placement frame 3 is connected to the first rotating shaft 401, and the inner end of the placement frame 3... The infusion stand 1 is connected by a steel wire rope 403. An internal movable groove 402 is provided, and a guide wheel 404 is installed on the inner wall of the movable groove 402. The other end of the steel wire rope 403 is connected to a connecting frame 405. A proximity switch 407 is installed at the bottom of the movable groove 402. A torsion spring 408 is sleeved on the outer side of the first rotating shaft 401. The two ends of the torsion spring 408 are connected to the infusion stand 1 and the placement rack 3, respectively. Through the setting of the reminder component 4, when the infusion bottle is placed, the connecting frame 405 is lifted upwards along the movable groove 402. During this process, the torsion spring 408 undergoes elastic deformation to store potential energy. At the same time, the connecting frame 405 moves out of the sensing range of the proximity switch 407 to avoid false alarms. When the infusion is completely finished, the connecting frame 405 slowly descends along the movable groove 402, and the bottom of the connecting frame 405 accurately touches the proximity switch 407, reminding the patient and their family. This device, through the setting of reminder component 4, solves the problems of patients or their families needing to constantly monitor the infusion process during infusion to avoid the potential threat to patient safety caused by air injection after the infusion is completed; it also avoids the problem of the transparent infusion bag surface reflecting light easily due to excessively strong ambient light, causing the boundary between the liquid surface and the container wall to be blurred; and it prevents the liquid surface from being difficult to accurately identify due to insufficient contrast between the liquid surface and the background under insufficient light or backlight conditions. Furthermore, if the observation angle is tilted, such as when the patient is lying down and looking up, the liquid surface will appear curved due to the perspective effect, further amplifying the visual error, making it impossible for medical staff or family members to accurately judge the remaining amount of medication, increasing the operational difficulty and potential risks of infusion management.

[0021] Furthermore, an indicator component 5 is provided on the top of the placement rack 3. The indicator component 5 includes a half gear 501, a second rotating shaft 502, a driven gear 503, and an indicator flag 504. The half gear 501 is fixedly connected to the outer surface of the first rotating shaft 401. The second rotating shaft 502 is rotatably connected to the top of the infusion rack 1. The driven gear 503 is fixedly connected to the center of the second rotating shaft 502, and the indicator flag 504 is fixedly connected to the outer side of the driven gear 503. Figure 5 As shown, this structure is used so that when the infusion bottle is placed at the hook of the placement rack 3, the first rotating shaft 401 rotates under the action of gravity. The half gear 501 and the driven gear 503 mesh with each other, driving the driven gear 503 to rotate, so that the indicator flag 504 is in a fallen state. When the infusion is continuous, the weight of the infusion bottle gradually decreases. Under the action of the connecting frame 405 and the torsion spring 408, the placement rack 3 is reset. When the placement rack 3 is reset, the half gear 501 drives the driven gear 503 to rotate in the opposite direction, so that the indicator flag 504 stands up, making it easy to observe from the outside.

[0022] Furthermore, a positioning component 6 is provided at the bottom of the infusion stand 1. The positioning component 6 includes an external thread 601, a positioning ring 602, and a tray 603. The external thread 601 is formed on the outer surface of the bottom of the infusion stand 1. The positioning ring 602 is connected to the outer thread of the external thread 601. The tray 603 is fixedly connected to the bottom of the infusion stand 1. The inner diameter of the positioning ring 602 is adapted to the diameter of the traveling wheel 7. Figure 2 As shown, this structure is used to move the infusion stand 1 to a designated position via the walking wheels 7, and then rotate the positioning ring 602 via the external thread 601 so that the positioning ring 602 covers the walking wheels 7 and contacts the ground, thereby lifting the walking wheels 7 off the ground and ensuring the stability of the infusion stand 1.

[0023] Furthermore, an audible and visual alarm 8 corresponding to the placement rack 3 is fixedly installed on the surface of the infusion stand 1, and the bottom of the proximity switch 407 is connected to the audible and visual alarm 8 via a wire. Figure 3 and Figure 4As shown, this structure is used to lower the connecting frame 405 under the weight of gravity after the infusion is completed via the infusion bottle, so that the connecting frame 405 contacts the proximity switch 407, thereby triggering the audible and visual alarm 8 to respond and remind the patient and staff.

[0024] Furthermore, an observation window 9 is snapped onto the outer side of the movable slot 402, facilitating disassembly. The observation window 9 is made of transparent material. Figure 3 and Figure 4 As shown, this structure is designed to allow for intuitive and indirect observation of the infusion location from the outside through the setting of the observation window 9, thereby determining the required time.

[0025] Furthermore, a weight 406 is placed inside the connecting bracket 405. For example... Figure 3 As shown, this structure is used to increase or decrease the weight 406 accordingly by using the demand.

[0026] Furthermore, a fixing bracket 604 is mounted on the surface of the positioning ring 602, and the number of fixing brackets 604 corresponds to the number of placement brackets 3. For example... Figure 2 As shown, this structure is used to facilitate the differentiation of items for different patients via the fixing bracket 604.

[0027] Furthermore, the shelf 3 is distinguished by different colors, with the weights 406 and indicator flags 504 corresponding to their colors. For example... Figure 1 and Figure 3 As shown, this structure is used to distinguish patients with different levels of health by color.

[0028] Working principle: When using, such as Figure 1 and Figure 2 As shown, first, the IV stand 1 is moved to the designated position using the wheels 7. Then, the positioning ring 602 is rotated via the external thread 601 until its bottom contacts the ground, thus positioning the IV stand 1. Then, according to different patients, the corresponding IV bottles are hung on the corresponding placement rack 3, such as... Figure 3 and Figure 5As shown, when the infusion bottle is suspended, the placement frame 3 rotates via the first rotating shaft 401, causing the torsion spring 408 to deform and pull the steel wire rope 403, which in turn drives the connecting frame 405 to rise along the movable groove 402, causing the connecting frame 405 to detach from the surface of the proximity switch 407. Simultaneously, as the first rotating shaft 401 rotates, the half-gear 501 on the surface drives the driven gear 503 to rotate, causing the indicator flag 504 to fall down. During continuous infusion, the weight of the infusion bottle gradually decreases, which is visually apparent through the external observation window 9. The infusion location is determined to estimate the required time. After the infusion is completed, the weight 406 and torsion spring 408 of the connecting frame 405 cause the connecting frame 405 to descend and the placement frame 3 to reset. When the placement frame 3 resets, the connecting frame 405 contacts the proximity switch 407 at the bottom. At the same time, the half gear 501 drives the driven gear 503 to rotate in the opposite direction, causing the indicator flag 504 to stand up for easy observation from the outside. This triggers the audible and visual alarm 8 to respond and remind the patient and staff. The above is the complete working principle of this invention.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
