Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a drug liquid volume detection device. Background Technology

[0002] In fields such as medical infusion, chemotherapy drug preparation, and laboratory drug dispensing, accurate monitoring of the remaining drug volume in drug containers is crucial. Traditional monitoring methods mainly rely on manual visual inspection, which is not only inefficient but also prone to misjudgment due to factors such as personnel fatigue and viewing angle, posing risks to medication safety.

[0003] In the existing technology, some automated liquid level detection devices have also emerged: for example, some devices detect medicine bottles of fixed specifications by installing sensors on fixed brackets, but these devices have poor versatility and cannot be adapted to medicine containers of different diameters and heights, which severely limits their application scenarios. Other devices installed at the bottle mouth are often not fixed securely enough and are prone to loosening and falling off during movement or collision, resulting in detection failure.

[0004] Therefore, we propose a liquid volume detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a liquid medicine volume detection device to solve the problems mentioned in the background art.

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

[0007] A liquid medicine volume detection device includes a conical sealing plug and an ultrasonic ranging sensor. An adjusting rod is threaded through and screwed onto the center of the conical sealing plug. The ultrasonic ranging sensor is installed at the bottom end of the adjusting rod, and a handle box is installed at the top end of the adjusting rod. An alarm, a controller, and a power supply are installed inside the handle box. Locking mechanisms are symmetrically arranged on both sides of the conical sealing plug. The locking mechanism includes a screw rotatably installed on the outer edge of the conical sealing plug, a movable plate threaded onto the outside of the screw, and an L-shaped clamp hinged below the movable plate. The L-shaped clamp flips up and down relative to the movable plate.

[0008] In a further embodiment, the conical sealing plug is further provided with a vertically penetrating vent hole, and a dustproof and breathable membrane is installed inside the vent hole.

[0009] In a further embodiment, the bottom of the conical sealing plug is provided with a receiving groove, and the inner dimension of the receiving groove is larger than the outer dimension of the ultrasonic ranging sensor.

[0010] In a further embodiment, the adjusting rod has a through groove inside, and the through groove extends through the inner bottom surface of the handle box.

[0011] In a further embodiment, a pressure cover is bolted to the top of the handle box, and the alarm extends through the top surface of the pressure cover.

[0012] In a further embodiment, a corrugated telescopic sleeve is fitted around the portion of the adjusting rod extending out of the top of the conical sealing plug. The bottom end of the corrugated telescopic sleeve is fixed to the top surface of the conical sealing plug, and the top end of the corrugated telescopic sleeve is rotatably connected to the bottom surface of the handle box through a bearing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention combines a conical sealing plug with an adjustable locking mechanism, enabling it to be securely installed on liquid medicine containers of different diameters and bottle mouth structures. This achieves multiple uses and broadens its application range. Furthermore, the locking mechanism formed by the screw, movable plate, and L-shaped clamp can tightly fasten the bottle mouth flange of the liquid medicine container from below, providing strong mechanical locking force and effectively preventing the device from falling off under vibration or accidental pulling, thus ensuring the stability of the detection process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A liquid medicine volume detection device mainly consists of a conical sealing plug 1, an adjusting rod 2, an ultrasonic ranging sensor 3, a handle box 4, and a locking mechanism.

[0025] The conical sealing plug 1 is made of medical-grade silicone material. Its conical structure allows it to fit the detection port 16 of different medicine bottles within a certain size range, achieving a preliminary seal. The adjusting rod 2 passes through the center of the conical sealing plug 1 and is screwed to it. Rotating the adjusting rod 2 can change the length of its bottom extension. The ultrasonic ranging sensor 3 is fixedly installed at the bottom of the adjusting rod 2 and is used to emit ultrasonic waves to the liquid surface and receive the echo. The handle box 4 is fixed at the top of the adjusting rod 2 and integrates an alarm 5, a controller 6 and a power supply 7. Specifically, the alarm 5 is a buzzer, the controller 6 is a microcontroller, and the power supply 7 is a button battery pack. The ultrasonic ranging sensor 3 is electrically connected to the controller 6 through a wire passing through the through slot 21.

[0026] The locking mechanisms are symmetrically arranged on both sides of the conical sealing plug 1. Each locking mechanism includes a screw 8 rotatably mounted on the plug body, a movable plate 9 screwed onto the screw 8, and an L-shaped clamp 10. The top of the L-shaped clamp 10 is hinged to the movable plate 9 by a pin, so that the L-shaped clamp 10 can flip up and down relative to the movable plate 9. When the L-shaped clamp 10 hangs down naturally, its bottom plate is parallel to the movable plate 9, forming a U-shaped clamp structure. When the screw 8 is rotated, the movable plate 9 is controlled not to rotate, so that the L-shaped clamp 10 can be driven up and down by the movable plate 9, thereby locking or releasing its bottom plate at the lower edge of the medicine bottle detection port 16.

[0027] As a preferred embodiment, the conical sealing plug 1 also has a vertically penetrating vent 11 inside, and a hydrophobic, dustproof, and breathable membrane 13 is installed inside the vent 11 to balance the air pressure while blocking microorganisms and dust.

[0028] The bottom of the conical sealing plug 1 is provided with a receiving groove 12, which is larger than the ultrasonic ranging sensor 3. When not in use, the sensor can be stored inside for protection.

[0029] The top of the handle box 4 is fitted with a cover 41 by bolts for easy battery replacement and maintenance. The sound and light components of the alarm 5 pass through the cover 41 for easy observation and hearing.

[0030] A corrugated telescopic sleeve 14 is fitted around the outer part of the adjusting rod 2, between the handle box 4 and the conical sealing plug 1. The bottom end of the telescopic sleeve is fixed to the top of the conical sealing plug 1, and the top end is rotatably connected to the bottom surface of the handle box 4 through a bearing ring 15. This design ensures both sealing and dust prevention, and does not hinder the rotation of the handle box 4 to adjust the height.

[0031] Workflow: Place the device above the detection port 16 of the medicine bottle, then flip the L-shaped clamps 10 on both sides upwards to prevent the bottom plate of the L-shaped clamps 10 from obstructing the pressing action of the conical sealing plug 1. After aligning and pressing the conical sealing plug 1 into the medicine bottle detection port 16, release the two L-shaped clamps 10. The L-shaped clamps 10 will automatically fall back under the action of gravity. At this time, the bottom plate of the L-shaped clamps 10 is under the flange of the medicine bottle detection port 16. Then rotate the screws 8 on both sides respectively. When rotating the screws 8, manually stop the movable plate 9 so that it cannot rotate with the screws 8. Thus, the movable plate 9 drives the L-shaped clamps 10 to move axially along the screws 8, causing the L-shaped clamps 10 to move upwards and tightly fasten to the lower edge of the bottle mouth, completing the stable installation of the device.

[0032] Then, according to the required liquid level height, rotate the handle box 4. The handle box 4 drives the adjusting rod 2 to rotate. Due to the thread action, the adjusting rod 2, together with the ultrasonic ranging sensor 3, rises or falls relative to the conical sealing plug 1, thereby adjusting the initial height of the sensor to the liquid surface. During this process, the corrugated telescopic sleeve 14 extends and retracts accordingly.

[0033] After the power supply 7 is turned on, the controller 6 controls the ultrasonic ranging sensor 3 to work continuously to measure the real-time distance to the liquid surface. When the medicine is consumed and the liquid level drops to the preset alarm threshold, the controller 6 immediately activates the alarm 5, issuing an audible and visual alarm to prompt medical staff to handle the situation in a timely manner.

[0034] During the dispensing of the medicine, external air enters the bottle through the dustproof and breathable membrane 13 to balance the negative pressure and ensure smooth dispensing of the medicine. After use, the locking mechanism is loosened and the device is removed from the bottle opening. The ultrasonic ranging sensor 3 can be adjusted to the position of retracting into the receiving tank 12 for protective storage.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
