Description

Technical Field

[0001] This utility model relates to the field of infusion pen technology, specifically to an infusion pen controlled by weight sensing. Background Technology

[0002] Currently, intravenous infusions are mostly administered using intravenous poles in hospitals and clinics. This method is not only space-saving but also convenient. When using an intravenous pole, the top of the pole is suspended from an infusion stand or the ceiling, and the infusion bottle or bag is hung on the infusion hook at the bottom of the pole before the infusion begins.

[0003] However, existing medical infusion poles often fail to deliver the infusion solution properly during use, especially for medications such as mannitol and sodium bicarbonate that require different dosages as prescribed by the doctor. The dosage is often difficult to control accurately. In addition, the infusion alarm will sound when the infusion level has already fallen below the drip chamber, making it more difficult to vent the air, and the infusion alarm is often lost.

[0004] Therefore, it is of great importance to design a weight-sensor controlled infusion pole to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention designs a weight-sensor-controlled infusion rod. This infusion rod aims to solve the technical problems of existing technologies, such as the inability to monitor and alarm the dosage of infusion fluid, the tendency to hang empty, which increases the difficulty of venting air, and the frequent loss of infusion alarms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A weight-sensor controlled infusion rod includes a telescopic rod with an alarm electronic scale suspended at its bottom. A quick-release ring is movably installed between the alarm electronic scale and the telescopic rod. Limit frames are fixedly connected to the bottom of the telescopic rod and on both sides of the alarm electronic scale. Stabilizing mechanisms are installed on the inner sides of both sets of limit frames. A lifting ring is movably installed at the bottom of the alarm electronic scale, and a hook is hung at the bottom of the lifting ring. An infusion frame is fixedly connected to the right side of the lifting ring and the hook.

[0008] As a preferred embodiment of this utility model, the telescopic boom consists of a connecting rod and a telescopic rod. The telescopic rod is slidably connected to the inside of the connecting rod. Two sets of locking blocks are symmetrically slidably connected inside the top of the telescopic rod. A first spring is movably installed at the opposite end of each of the two sets of locking blocks. Multiple sets of adjustment holes adapted to the locking blocks are opened on the outside of the connecting rod.

[0009] As a preferred embodiment of this utility model, an audible and visual alarm is fixedly installed on the top of the alarm electronic scale, and the audible and visual alarm is electrically connected to the alarm electronic scale.

[0010] As a preferred embodiment of this utility model, the quick-release ring includes a connecting ring movably installed between the telescopic rod and the alarm electronic scale. The bottom end of the connecting ring is rotatably connected to a docking post, and the top end of the connecting ring is fixedly connected to a docking block. A docking groove is provided at the top end of the docking post corresponding to the docking block. A locking sleeve is slidably connected to the outside of the docking post, and the locking sleeve is threadedly connected to the docking block.

[0011] As a preferred embodiment of this utility model, the stabilizing mechanism includes positioning plates slidably connected to the inner sides of two sets of limiting frames. The upper and lower ends of the two sets of positioning plates are slidably connected to the limiting frames through sliding columns, and a second spring is fixedly connected between the two sets of positioning plates and the limiting frames.

[0012] As a preferred embodiment of this utility model, a limiting block is fixedly connected to one end of the sliding column located outside the limiting frame, and a rubber protective plate is fixedly connected to the inner side of the positioning plate.

[0013] As a preferred embodiment of this utility model, the upper and lower ends of the left side of the infusion frame are fixedly connected with mounting rods, and the two sets of mounting rods are fixedly connected to the lifting ring and the hook respectively by fixing screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, through the coordinated design of the telescopic boom, alarm electronic scale, quick-release ring, hanging ring, hook, and infusion frame, the extension length of the telescopic boom can be adjusted as needed during infusion. The alarm electronic scale is then assembled at the bottom of the telescopic boom via the quick-release ring. After the medication bottle is placed inside the infusion frame, the weight of the medication is measured by the alarm electronic scale. An alarm weight is then set on the alarm electronic scale. When the alarm weight is higher than the zero value, the weight is reduced to the alarm weight before the medication is almost finished infused, triggering an alarm. An audible and visual alarm provides a prompt, thus monitoring the medication infusion dosage. When using large volumes of liquid (e.g., 3000 ml), the change in weight indicates how much has been used and how much remains, allowing for more accurate control of infusion and outflow, facilitating nurse shift changes, avoiding issues such as empty hangs increasing venting difficulty and frequent loss of the infusion alarm, greatly improving the safety of the infusion boom.

[0016] 2. In this utility model, through the cooperative design of the limiting frame and the stabilizing mechanism, after the alarm electronic scale is assembled at the bottom of the telescopic rod, the alarm electronic scale is located inside the limiting frame. Then, two sets of positioning plates are placed against the left and right sides of the alarm electronic scale. Under the action of the second spring, the alarm electronic scale is positioned and restricted, thereby improving the stability of the alarm electronic scale after it is assembled with the telescopic rod, and thus improving the accuracy of weighing infusion bottles.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A weight-sensor controlled infusion rod includes a telescopic rod 1, an alarm electronic scale 2 suspended at the bottom of the telescopic rod 1, a quick-release ring 3 movably installed between the alarm electronic scale 2 and the telescopic rod 1, limit frames 4 fixedly connected to the bottom of the telescopic rod 1 and on both the left and right sides of the alarm electronic scale 2, stabilizing mechanisms 5 installed on the inner sides of both sets of limit frames 4, a hanging ring 6 movably installed at the bottom of the alarm electronic scale 2, a hook 7 hanging at the bottom of the hanging ring 6, and an infusion frame 8 fixedly connected to the right side of the hanging ring 6 and the hook 7.

[0026] First, the telescopic boom 1 consists of a connecting rod 101 and a telescopic rod 102. The telescopic rod 102 is slidably connected to the inside of the connecting rod 101. Two sets of locking blocks 103 are symmetrically slidably connected to the inside of the top of the telescopic rod 102. A first spring 104 is movably installed at the opposite end of each set of locking blocks 103. Multiple sets of adjustment holes 105 adapted to the locking blocks 103 are opened on the outside of the connecting rod 101. Under the action of the first spring 104, the locking blocks 103 are pushed out from the inside of the telescopic rod 102 so that the locking blocks 103 are locked into the inside of the adjustment holes 105, thereby fixing the telescopic rod 102. Pressing the locking blocks 103 causes them to retract into the inside of the connecting rod 101, thereby releasing the fixation of the telescopic rod 102 and allowing the extension length of the telescopic rod 102 to be adjusted as needed.

[0027] Furthermore, an audible and visual alarm 201 is fixedly installed on the top of the alarm scale 2, and the audible and visual alarm 201 is electrically connected to the alarm scale 2. During the infusion process, after the medicine bottle is placed inside the infusion frame 8, the weight of the medicine is measured by the alarm scale 2. Then, the alarm scale 2 is operated to set an alarm weight. When the alarm weight is higher than the zero value, the weight can be reduced to the alarm weight before the medicine is finished being infused, and an alarm is triggered by the audible and visual alarm 201. This allows for monitoring and alarming of the infusion dosage, while avoiding the problems of empty hangers increasing the difficulty of venting and frequent loss of the infusion alarm, greatly improving the safety of the infusion pole.

[0028] Then, the quick-release ring 3 includes a connecting ring 301 movably installed between the telescopic rod 102 and the alarm electronic scale 2. The bottom end of the connecting ring 301 is rotatably connected to a docking post 302, and the top end of the connecting ring 301 is fixedly connected to a docking block 303. A docking groove 304 is opened at the top end of the docking post 302 at a position corresponding to the docking block 303. A locking sleeve 305 is slidably connected to the outside of the docking post 302, and the locking sleeve 305 is threadedly connected to the docking block 303. In use, the connecting ring 301 is hung between the telescopic rod 102 and the alarm electronic scale 2. Then, the docking post 302 is rotated to align the docking groove 304 at its top end with the docking block 303. Finally, the locking sleeve 305 is slid upward and rotated to lock the docking post 302 and the docking block 303, thereby facilitating the assembly of the alarm electronic scale 2 at the bottom end of the telescopic rod 102 and improving the ease of use.

[0029] Furthermore, the stabilizing mechanism 5 includes positioning plates 501 slidably connected to the inner sides of the two sets of limiting frames 4. The upper and lower ends of the two sets of positioning plates 501 are slidably connected to the limiting frames 4 through sliding columns 502. A second spring 503 is fixedly connected between the two sets of positioning plates 501 and the limiting frames 4. After the alarm electronic scale 2 is installed at the bottom end of the telescopic rod 102, the alarm electronic scale 2 is located inside the limiting frame 4. Then, the two sets of positioning plates 501 are pressed against the left and right sides of the alarm electronic scale 2. Under the action of the second spring 503, the alarm electronic scale 2 is positioned and restricted, thereby improving the stability of the alarm electronic scale 2 after being assembled with the telescopic rod 102, and thus improving the accuracy of weighing the infusion bottle.

[0030] Secondly, a limiting block 504 is fixedly connected to one end of the sliding column 502 located outside the limiting frame 4, and a rubber protective plate 505 is fixedly connected to the inner side of the positioning plate 501. The sliding column 502 is restricted by the limiting block 504. When the positioning plate 501 is used to position and restrict the outside of the alarm electronic scale 2, it can not only improve the friction to ensure the positioning effect, but also protect the outside of the alarm electronic scale 2 to avoid damage.

[0031] Finally, mounting rods 801 are fixedly connected to both the upper and lower ends of the left side of the infusion frame 8. Both sets of mounting rods 801 are fixedly connected to the lifting ring 6 and the hook 7 respectively by fixing screws 802. After the two sets of mounting rods 801 are pressed against the lifting ring 6 and the hook 7 respectively, the mounting rods 801 are fixed by fixing screws 802, thereby installing the infusion frame 8 under the alarm electronic scale 2. This makes it convenient for the alarm electronic scale 2 to weigh infusion bottles, and it can also weigh items normally after the infusion frame 8 is disassembled, thus improving the versatility of the alarm electronic scale 2.

[0032] In this embodiment, the specific implementation scenario is as follows: During the infusion process, the extension length of the telescopic rod 102 can be adjusted as needed. Then, the alarm electronic scale 2 is assembled to the bottom end of the telescopic rod 102 via the quick-release ring 3. The alarm electronic scale 2 is located inside the limiting frame 4. Subsequently, two sets of positioning plates 501 are placed against the left and right sides of the alarm electronic scale 2. Under the action of the second spring 503, the alarm electronic scale 2 is positioned and limited, thereby improving the stability of the alarm electronic scale 2 after being assembled with the telescopic rod 102. After the medicine bottle is placed inside the infusion frame 8, the weight of the medicine is measured by the alarm electronic scale 2. Then, the alarm electronic scale 2 is operated to set an alarm weight. When the alarm weight is higher than the zero value, the medicine bottle can be placed in the infusion frame 8. When the weight of the IV drip bottle decreases to the alarm weight just before the drip is finished, an alarm is triggered via the audible and visual alarm 201. This allows for monitoring and alarming of the infusion dosage. When using large volumes of fluid (such as 3000 ml), the change in weight indicates how much has been used and how much remains, enabling more accurate control of intake and output and facilitating nurse shift handover. The entire operation is simple and convenient. Compared with existing IV drip poles, this invention, through its design, can monitor and alarm the infusion dosage and ensure the accuracy of IV bottle weighing, thus avoiding the problems of empty hangers increasing the difficulty of venting air and frequent loss of IV alarms, greatly improving the safety of IV drip pole use.
