Description

Technical Field

[0001] This utility model relates to a novel infusion alarm device, belonging to the field of alarm device technology. Background Technology

[0002] Previously, when patients received intravenous infusions, medical staff would manually monitor the amount of medication in the infusion bottle. However, sometimes due to negligence by medical staff, the medication might run out, causing blood to flow back into the patient's body. As a result, infusion alarms were gradually developed. When the medication in the infusion bottle / bag is about to run out, the infusion alarm will sound an alarm signal. After receiving the alarm signal, medical staff will promptly replace the infusion bottle / bag to protect the patient's safety.

[0003] Chinese Patent Publication No. (CN 202236609 U) discloses a novel infusion alarm device, belonging to the field of alarm device technology. It includes an infusion stand, with an alarm triggering device at the top of the stand. The triggering device includes a guide groove, a slider on the guide groove, a spring on the top of the slider, and the other end of the spring connected to the guide groove. An alarm contact is located above the guide groove, and a metal contact is located on the slider. The alarm contact is connected in series with the alarm device and a battery via a wire, and the other end of the battery is connected to the metal contact via a wire. The metal contact corresponds to and is located below the alarm contact. This invention features a simple structure, eliminates the need for dedicated personnel during infusion, and automatically alarms upon completion of the infusion, reducing the workload of caregivers.

[0004] The aforementioned device only serves as a simple noise alarm. If medical staff or caregivers do not notice the alarm noise in time, the infusion bottle will continue to inject the residual medication into the patient. Furthermore, elderly people or young children may not be able to turn off the flow regulation switch on the infusion bottle themselves during infusion, which may still lead to blood backflow or air entering the vein, posing a safety hazard to the patient.

[0005] Therefore, a new type of infusion alarm is proposed. Utility Model Content

[0006] In view of this, the present invention provides a novel infusion alarm to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A novel infusion alarm includes a base plate, a vertical rod fixedly installed on the top of the base plate, a housing fixedly installed on the top of the vertical rod, an alarm mechanism provided on the surface of the housing, the alarm mechanism including a mounting block and a box, the mounting block being disposed in the inner cavity of the housing, a rigid spring fixedly installed on the top of the mounting block, the other end of the rigid spring being fixedly installed on the top of the inner cavity of the housing, the box being disposed on the front side of the housing, a drive motor being disposed on the top of the box, an adjusting plate being fixedly connected to the output end of the drive motor, and connecting plates being movably connected to the bottom of the adjusting plate. The bottom of each of the two connecting plates is movably connected to a movable block, the bottom of each of the two movable blocks is fixedly installed with a fixing rod, and the other end of each of the two fixing rods is fixedly installed with a clamping plate. An alarm speaker is fixedly installed on the top of the box, and a first contact sensor switch is fixedly installed on the surface of the box. The first contact sensor switch is electrically connected to the input terminal of the alarm speaker. A second contact sensor switch is fixedly installed on the top of the drive motor. The second contact sensor switch is electrically connected to the input terminal of the drive motor. A hook is fixedly installed on the bottom of the box, and both the alarm speaker and the drive motor are electrically connected to an external power supply.

[0008] More preferably, mounting rods are fixedly installed on both the left and right sides of the front side of the mounting block, and L-shaped plates are fixedly installed on the front sides of the two mounting rods. The housing is fixedly installed on the bottom of the L-shaped plate, and the drive motor is fixedly installed on the top of the L-shaped plate.

[0009] More preferably, the dimensions of the second contact sensor switch and the limit rod are consistent, and the second contact sensor switch and the limit rod are both in the same vertical direction.

[0010] More preferably, the bottom of each box is provided with a limit rod, and the two clamping plates are slidably connected to the surfaces of the two limit rods.

[0011] More preferably, the bottom of the box is provided with movable slots on both the left and right sides, and the two fixed rods pass through the inner cavity of the two movable slots and extend to the bottom of the box.

[0012] More preferably, a guide rod is fixedly installed in the inner cavity of the box, and the two moving blocks are slidably connected to the left and right sides of the guide rod surface.

[0014] More preferably, the bottom of the base plate is movably connected to U-shaped plates around its four sides via pivots, and the inner sides of the four U-shaped plates are movably connected to movable wheels.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model incorporates an alarm mechanism. When the IV drip is completely emptied, the bottle becomes lighter, causing a change in the force on the rigid spring. This causes the mounting block to move the L-shaped plate upwards, bringing the second and first contact switches into contact. The first contact switch activates the alarm speaker, while the second contact switch drives the motor to rotate the adjusting plate. This causes the fixing rod to move the clamping plate inwards, clamping the IV tubing and stopping the injection of any remaining fluid.

[0017] II. This utility model, by setting a limiting rod, can keep the infusion tube inside the clamp, preventing it from moving out of the clamp and affecting the clamping operation. By setting a moving groove, the movement of the fixed rod can be limited, preventing it from deviating during movement and affecting the stopping of injection of residual liquid in the infusion tube. By setting a guide rod, the movement of the moving block can be limited, preventing it from changing direction during movement and affecting the clamping operation of the infusion tube. By setting a sliding rod, the movement of the mounting block can be guided, preventing it from deviating during movement and affecting the clamping operation of the infusion tube. By setting a movable wheel, the entire device can be easily moved, allowing for convenient adjustment of its position according to the user's needs.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6As shown, this utility model embodiment provides a novel infusion alarm, including a base plate 1, a vertical rod 3 fixedly installed on the top of the base plate 1, a box body 4 fixedly installed on the top of the vertical rod 3, an alarm mechanism 2 provided on the surface of the box body 4, the alarm mechanism 2 including a mounting block 201 and a housing 205, the mounting block 201 being disposed in the inner cavity of the box body 4, a rigid spring 202 fixedly installed on the top of the mounting block 201, the other end of the rigid spring 202 being fixedly installed on the top of the inner cavity of the box body 4, the housing 205 being disposed on the front side of the box body 4, a drive motor 206 being disposed on the top of the housing 205, an adjusting plate 207 being fixedly connected to the output end of the drive motor 206, connecting plates 208 being movably connected to the bottom of each adjusting plate 207, moving blocks 209 being movably connected to the bottom of each of the two connecting plates 208, fixing rods 210 being fixedly installed to the bottom of each of the two moving blocks 209, and clamping plates 211 being fixedly installed to the other end of each of the two fixing rods 210, the box body 4... An alarm speaker 212 is fixedly installed on the top. A first contact sensor switch 213 is fixedly installed on the surface of the housing 4. The first contact sensor switch 213 is electrically connected to the input terminal of the alarm speaker 212. A second contact sensor switch 214 is fixedly installed on the top of the drive motor 206. The second contact sensor switch 214 is electrically connected to the input terminal of the drive motor 206. A hook 7 is fixedly installed on the bottom of the housing 205. Both the alarm speaker 212 and the drive motor 206 are electrically connected to an external power supply. Mounting rods 203 are fixedly installed on the left and right sides of the front side of the mounting block 201. An L-shaped plate 204 is fixedly installed on the front side of the two mounting rods 203. The housing 205 is fixedly installed on the bottom of the L-shaped plate 204. The drive motor 206 is fixedly installed on the top of the L-shaped plate 204. The dimensions of the second contact sensor switch 214 and the limit rod 215 are consistent with each other. The second contact sensor switch 214 and the limit rod 215 are both in the same vertical direction.

[0031] By setting up alarm mechanism 2, when the liquid in the IV drip bottle is finished, the bottle becomes lighter. At this time, the force on the rigid spring 202 changes, causing the mounting block 201 to move the L-shaped plate 204 upward. This causes the second contact sensor switch 214 and the first contact sensor switch 213 to contact each other. The first contact sensor switch 213 drives the alarm speaker 212 to emit an alarm sound, while the second contact sensor switch 214 causes the drive motor 206 to drive the adjusting plate 207 to rotate. This causes the fixing rod 210 to move the clamping plate 211 inward and clamp the IV tubing, stopping the injection of residual liquid in the IV tubing. This solves the problem of some people not knowing how to turn off the flow regulating switch, ensuring the safety of patients during IV infusion and making it convenient for operators to use.

[0032] Example 2

[0033] like Figure 1-5As shown, in one embodiment, the bottom of the box 205 is provided with a limiting rod 215, and two clamping plates 211 are slidably connected to the surfaces of the two limiting rods 215. The left and right sides of the bottom of the box 205 are provided with moving grooves 216. Two fixing rods 210 pass through the inner cavity of the two moving grooves 216 and extend to the bottom of the box 205. A guide rod 217 is fixedly installed in the inner cavity of the box 205. Two moving blocks 209 are slidably connected to the left and right sides of the surface of the guide rod 217. Sliding rods 218 are fixedly installed on the left and right sides of the inner cavity of the box 4. The mounting block 201 is slidably connected to the surface of the two sliding rods 218. U-shaped plates 5 are movably connected to the bottom of the bottom plate 1 through a rotating shaft. The inner sides of the four U-shaped plates 5 are movably connected with movable wheels 6.

[0034] By setting a limiting rod 215, the infusion tube can be kept inside the clamping plate 211, preventing it from moving out of the clamping plate 211 and affecting the clamping operation. By setting a moving groove 216, the movement of the fixed rod 210 can be limited, preventing it from shifting during movement and affecting the stopping of injection of residual liquid in the infusion tube. By setting a guide rod 217, the movement of the moving block 209 can be limited, preventing it from changing direction during movement and affecting the clamping operation of the infusion tube. By setting a sliding rod 218, the movement of the mounting block 201 can be guided, preventing it from shifting during movement and affecting the clamping operation of the infusion tube. By setting a movable wheel 6, the entire device can be easily moved, and its position can be easily adjusted according to the user's needs.

[0035] In operation, this invention involves hanging the IV drip bottle on the hook 7 with the IV tubing positioned inside the clamp 211. Due to the influence of the IV drip bottle, the housing 205 moves the L-shaped plate 204, mounting rod 203, rigid spring 202, and mounting block 201 downwards synchronously. The rigid spring 202 deforms under the influence of force. As the liquid in the IV drip bottle gradually decreases, the force on the rigid spring 202 gradually diminishes, allowing the rigid spring 202 to use its own tension to drive the mounting block 201, rigid spring 202, mounting rod 203, L-shaped plate 204, and... The equipment connected to the surface of the L-shaped plate 204 moves upward synchronously. At this time, the second contact sensor switch 214 and the first contact sensor switch 213 come into contact with each other, thereby driving the alarm speaker 212 and the drive motor 206 to output. The alarm speaker 212 emits an alarm sound, and the drive motor 206 drives the adjusting plate 207 to swing. Through the cooperation of the adjusting plate 207 and the connecting plate 208, the moving block 209 drives the fixed rod 210 and the clamping plate 211 to move inward and clamp the infusion tube. At this time, the infusion tube stops the infusion work to the patient due to the compression.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
