Description

Technical Field

[0001] This invention belongs to the field of medical injection equipment technology, specifically relating to a structure and method for detecting the installation of medicine bottles. Background Technology

[0002] In many medical diagnostic and interventional procedures, doctors or other personnel inject patients with saline or contrast agents to assist in diagnosis and treatment, in conjunction with computed tomography (CT), digital subtraction angiography (DSA), and magnetic resonance imaging (MR). The contrast injection device injects contrast agents or saline into specific areas of the body to obtain enhanced images of those areas, aiding in diagnosis.

[0003] Currently, high-pressure contrast injection devices on the market are mainly divided into two categories:

[0004] One type involves directly installing a syringe on the injection device. The operator manually controls the syringe to draw in and expel the medication, thus achieving the function of drug aspiration and injection. This type of device does not require a vial holder. The operator manually controls the device, resulting in low efficiency. Each time medication is drawn, the operator needs to operate manually, which is labor-intensive.

[0005] Another type involves first installing the medicine bottle into the medicine bottle mounting structure, and then using the equipment's automatic control system to complete the suction and exhaust of the medicine, thus realizing the drug injection function. This method is simpler to operate and more efficient, and has become the mainstream application.

[0006] However, most existing mainstream high-pressure injection devices have simple structural frames that can only perform basic bottle installation functions, and have the following significant drawbacks:

[0007] First, there is a lack of reliable detection mechanisms for ensuring the correct placement of the vial. Existing technologies mostly employ contact sensors such as microswitches. During injection, highly osmotic contrast agents are prone to leakage or crystallization. Leaked medication can contaminate or even damage the sensor's mechanical contacts or circuitry, leading to detection failure, equipment malfunction, and subsequent cleaning being extremely difficult.

[0008] Secondly, there is a lack of a leak-proof design when removing the bottle. When the medicine bottle is pulled out vertically, the residual medicine inside can easily leak from the puncture needle, causing waste of medicine and environmental pollution.

[0009] Third, the system lacks an intelligent function to determine the remaining liquid in the vial. The inability to automatically determine whether the medication in the vial has been completely aspirated may result in air being drawn in, requiring additional venting, reducing injection efficiency, and even affecting image quality. Summary of the Invention

[0010] To address the aforementioned technical problems, this invention proposes a structure and method for detecting the installation of medicine bottles.

[0011] To achieve the above objectives, the technical solution of the present invention is as follows:

[0012] On one hand, this invention discloses a medicine bottle installation and detection structure, comprising: a plurality of medicine bottle installation components, each medicine bottle installation component comprising:

[0013] Medicine bottle holder, used to hold and secure medicine bottles;

[0014] The installation detection unit includes an infrared sensor and a sensor kit. The sensor kit is fixedly installed at the corresponding position of the bottle opening on the medicine bottle mounting base. The infrared sensor is installed inside the sensor kit. The installation detection unit is used to detect whether the medicine bottle is installed in place in a non-contact manner.

[0015] A rotating anti-leakage mechanism is connected to the medicine bottle mounting base and is used to drive the medicine bottle mounting base to rotate and switch between a vertical installation position and a horizontal bottle removal position.

[0016] A bubble sensor, mounted on the medicine bottle mounting base, is used to detect air bubbles in the suction tubing connected to the medicine bottle.

[0017] A gravity sensor, mounted on the medicine bottle mounting base, is used to detect the real-time weight of the medicine bottle mounted on the medicine bottle mounting base.

[0018] In view of the deficiencies of the prior art pointed out in the background art, the present invention discloses a medicine bottle installation and detection structure, which has the following beneficial effects:

[0019] First, this invention fundamentally changes the detection method by setting up a non-contact installation and detection unit. The sensor kit physically isolates the infrared sensor from the medicine bottle installation space, so that the detection process does not require direct contact with the medicine bottle. This effectively avoids contamination of sensor contacts or circuits by leakage or crystallization of hypertonic contrast agents, thereby significantly improving the long-term reliability and stability of the detection and solving the problems of detection failure and subsequent cleaning caused by sensor damage.

[0020] Secondly, the medicine bottle installation and detection structure integrates a rotating anti-leakage mechanism. This mechanism can drive the medicine bottle mounting base to rotate from a vertical working position to a horizontal bottle removal position. When the medicine bottle is removed in the horizontal position, gravity can keep the residual medicine inside away from the puncture needle interface area, greatly reducing the risk of medicine leakage from the puncture needle, reducing medicine waste, and maintaining a clean operating environment.

[0021] Third, a gravity sensor is installed on the vial mount, which can detect changes in the vial's weight in real time. By monitoring the weight decay during the aspiration process and comparing it with a pre-stored threshold, the system can automatically and accurately determine whether the medication in the vial is about to be completely drawn. This avoids the situation where air is drawn in due to the medication being completely drained, reduces unnecessary venting operations, and improves the efficiency and automation level of the injection process.

[0022] This invention systematically solves three major industry pain points—easy failure of medicine bottle detection, easy leakage when removing the bottle, and difficulty in judging the remaining amount—through an integrated structural design that combines non-contact installation detection, rotational leak prevention, and gravity sensing detection. It significantly improves the reliability, operational safety, and intelligence level of high-pressure injection devices.

[0023] Based on the above technical solution, the following improvements can be made:

[0024] As a preferred embodiment, the medicine bottle mounting base includes: a base body, a bottle holder, and at least two side plates located on the outside of the bottle holder, the side plates being used to wrap around and secure the medicine bottle from the side.

[0025] By adopting the above-mentioned preferred solution, it is ensured that the medicine bottle does not shake or loosen during the high-speed injection process of the equipment, thereby improving the mechanical stability and safety of the system.

[0026] As a preferred embodiment, the side plate is provided with a bottle clamping part, which extends at an angle towards the center of the bottle holder and can undergo elastic deformation to change the angle between itself and the side plate, thereby clamping the medicine bottle.

[0027] By adopting the above-mentioned preferred solution, a bottle clamping part that can be elastically deformed is provided on the side plate. Through the inclined extension and elastic deformation of the bottle clamping part, it can not only adapt to medicine bottles of different diameters, but also further fix the medicine bottles through elastic clamping force. This solves the problem that the traditional fixing structure can only adapt to a single size of medicine bottle and the clamping force is insufficient. At the same time, the elastic deformation design avoids hard contact damage to the outer wall of the medicine bottle.

[0028] As a preferred embodiment, the side panel has a hollow section, and the bottle clamping section is a convex strip structure located at the hollow section position.

[0029] By adopting the above-mentioned preferred solution, the hollow part provides sufficient deformation space for the T-shaped bar bottle clamping part, ensuring that the bottle clamping part can stretch and contract flexibly and improving the clamping reliability; the T-shaped bar structure makes the bottle clamping part more evenly stressed and the elastic recovery force stable. At the same time, the hollow design reduces the overall weight of the side plate, optimizes the structural layout, and balances the clamping effect with the lightweight structure.

[0030] As a preferred embodiment, the base is provided with a puncture device fixing seat for installing a puncture device and a suction tube fixing seat for fixing a suction tube; the suction tube fixing seat is provided with a slot for fixing the suction tube; the air bubble sensor is set at the slot.

[0031] By adopting the above-mentioned preferred solution, the puncture device fixing seat and the drug suction line fixing seat are integrated on the base body, realizing the integrated fixing of the puncture device and the drug suction line, reducing assembly errors caused by the scattered installation of components; the slot design makes the drug suction line more securely fixed, avoiding the displacement of the line from affecting the accuracy of bubble detection. At the same time, the bubble sensor is set at the corresponding position of the slot, shortening the detection distance, improving the bubble recognition sensitivity, and timely avoiding the risk of bubbles entering the human body or affecting the injection effect.

[0032] As a preferred embodiment, the rotating leak-proof mechanism includes:

[0033] A rotating fixing rod is inserted through a fixing hole at the bottom of the medicine bottle mounting base, which allows several medicine bottle mounting bases to rotate independently around it.

[0034] A slide key, which can be moved vertically.

[0035] The slide key fixing plate is installed on the equipment base and is used to install the slide key;

[0036] The longitudinal elastic element is connected between the equipment base and the slide key fixing plate, and is used to provide the slide key with a reset elastic force.

[0037] The fixing buckle is movable in a horizontal direction and has a fixing terminal on its side;

[0038] The retaining cover is used to accommodate the retaining buckle.

[0039] A lateral elastic element is connected between the fixing buckle and the inner wall of the fixing buckle cover.

[0040] The sliding key fixing plate is provided with a wedge-shaped protrusion, and the fixing buckle is provided with a beveled groove that matches the wedge-shaped protrusion. The beveled surface of the wedge-shaped protrusion is connected to the beveled surface of the beveled groove.

[0041] The medicine bottle mounting base is provided with slots that mate with the fixed terminals;

[0042] The up-and-down movement of the sliding key can drive the fixing buckle to move horizontally by cooperating with the inclined surface of the wedge-shaped protrusion and the inclined surface of the groove, so that the fixing terminal can be inserted into or removed from the slot of the medicine bottle mounting base, thereby realizing the locking or unlocking of the medicine bottle mounting base and the equipment base; after unlocking, the medicine bottle mounting base can rotate around the rotating fixing rod to the horizontal bottle removal position.

[0043] Using the above-mentioned preferred solution, the simple up-and-down movement of the sliding key can be reliably converted into the horizontal locking / unlocking movement of the fixed buckle via the inclined mechanism, achieving one-button operation and providing a good user experience. The self-locking mechanism utilizes the restoring force of the elastic element to ensure the stable locking of the medicine bottle mounting base in the vertical working position, preventing accidental rotation.

[0044] As a preferred embodiment, the medicine bottle installation and detection structure includes multiple medicine bottle installation components, each medicine bottle mounting base is arranged in parallel via the same rotating fixing rod, and can rotate independently.

[0045] By adopting the above-mentioned preferred scheme, multiple sets of medicine bottle mounting components are arranged side by side through the same rotating fixing rod, which not only optimizes the structural layout of multi-medicine bottle installation and reduces space occupation, but also enables each medicine bottle mounting seat to rotate independently and be controlled separately. Any medicine bottle can be flexibly used as needed without affecting the installation or use status of other medicine bottles, thereby improving the operational flexibility and efficiency in multi-medicine bottle scenarios.

[0046] As a preferred option, the sensor kit is a transparent acrylic cover.

[0047] By adopting the above-mentioned preferred solution, a transparent acrylic cover is used as the sensor kit. On the one hand, it can penetrate infrared signals without obstruction, ensuring the accuracy of non-contact detection and avoiding detection errors caused by signal attenuation. On the other hand, the acrylic cover achieves physical isolation between the infrared sensor and the installation space of the medicine bottle, completely blocking the leakage path of contrast agent and preventing the sensor or circuit board from being contaminated or damaged. At the same time, the acrylic cover material is resistant to contrast agent corrosion and easy to clean, reducing equipment maintenance costs.

[0048] On the other hand, this invention discloses a method for detecting the installation of medicine bottles, applicable to any of the above-mentioned medicine bottle installation detection structures, comprising:

[0049] An infrared sensor, located at the bottle opening of the medicine bottle mounting base and isolated by the sensor kit, detects whether the medicine bottle is installed in place in a non-contact manner.

[0050] When the medicine bottle is detected to be installed in place, the automatic medicine suction program is triggered;

[0051] During the drug inhalation process, the drug inhalation tubing is monitored in real time by a bubble sensor, and the drug inhalation is stopped when a bubble is detected.

[0052] The weight information of the medicine bottle is obtained in real time by gravity sensor and compared with the pre-stored empty bottle weight threshold corresponding to the medicine bottle specification. When the weight information is close to or reaches the empty bottle weight threshold, it is determined that the medicine liquid in the medicine bottle has been completely drawn.

[0053] When it is necessary to remove the medicine bottle, control the rotating anti-leakage mechanism to rotate the medicine bottle mounting base to the horizontal bottle removal position before removing the medicine bottle.

[0054] This invention discloses a method for testing the installation of medicine bottles. This method combines non-contact testing, automatic drug aspiration, air bubble monitoring, remaining volume judgment, and leak-proof bottle removal in an orderly manner, so that the entire injection preparation process does not require manual step-by-step judgment and operation, which greatly improves the efficiency, standardization and safety of medical operations and reduces the risks caused by differences in operator experience.

[0055] As a preferred embodiment, before acquiring the weight information of the medicine bottle in real time via a gravity sensor, the following steps are also included:

[0056] The specification information of the medicine bottle is obtained through the barcode scanning module. Based on the specification information, the pre-stored full bottle weight threshold and empty bottle weight threshold for the corresponding specification are retrieved.

[0057] By adopting the above-mentioned preferred solution, the bottle specifications are obtained through the barcode scanning module and the corresponding weight threshold is retrieved, which solves the judgment error problem caused by the weight difference of different bottle specifications. The pre-stored full / empty bottle weight threshold is used as the judgment benchmark, which makes the detection of the remaining liquid in the gravity sensor more accurate, avoids incomplete or excessive drug absorption due to unclear bottle specifications, further improves the reliability of automatic control, and reduces drug waste and ineffective equipment operation.

Detailed Implementation

[0074] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0075] 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.

[0076] The expression “includes” is an “open-ended” expression, which means that there is a corresponding component or step, and should not be interpreted as excluding additional components or steps.

[0077] To achieve the objectives of this invention, some embodiments of the medicine bottle installation detection structure, such as Figure 1-2 As shown, the medicine bottle installation detection structure a includes three independent medicine bottle installation components a.

[0078] like Figure 3-4 As shown, each medicine bottle mounting assembly a includes: a medicine bottle mounting base 1, a mounting detection unit 2, a rotating anti-leakage mechanism 3, a bubble sensor (not shown in the figure), and a gravity sensor (not shown in the figure).

[0079] The medicine bottle mounting base 1 has an overall frame structure and is used to support and fix the medicine bottle.

[0080] The detection unit 2 includes an infrared sensor 21 and a sensor kit 22. The sensor kit 22 is fixedly installed at the corresponding position of the bottle opening of the medicine bottle mounting base 1 (specifically installed at the position of the hole 121 of the bottle holder 12 described below). The infrared sensor 21 is installed inside the sensor kit 22, and the sensor kit 22 completely isolates the infrared sensor 21 from the medicine bottle mounting space.

[0081] The detection principle diagram of infrared sensor 21 is as follows: Figure 5 As shown, it integrates an infrared transmitter and receiver. When the transmitter sends out the infrared sensor signal, if the medicine bottle is not installed, the transmitted signal will not be reflected back. If the receiver cannot receive the transmitted signal, it will determine that the medicine bottle is not installed or has been removed. When the medicine bottle is installed on the medicine bottle holder, the mouth of the medicine bottle will reflect the infrared signal emitted by the transmitter of the infrared sensor to the detection board. The receiver receives the reflected signal, and the hardware automatically recognizes a level transition, thereby detecting that the medicine bottle has been installed in place.

[0082] The rotating anti-leakage mechanism 3 is connected to the medicine bottle mounting base 1 and is used to drive the medicine bottle mounting base 1 in a vertical installation position (e.g., Figure 1 (as shown) and the horizontal bottle-taking position (as shown) Figure 2 Rotate between (as shown).

[0083] A bubble sensor is installed on the medicine bottle mounting base 1 to detect air bubbles in the suction tubing connected to the medicine bottle. A gravity sensor is installed on the medicine bottle mounting base 1 to detect the real-time weight of the medicine bottle mounted on the medicine bottle mounting base 1.

[0084] Three vial mounting components a are arranged side by side and connected as a whole by the rotating anti-leakage mechanism 3 described in a subsequent embodiment, which can simultaneously install one saline bottle and two contrast agent bottles of different concentrations.

[0085] In view of the deficiencies of the prior art pointed out in the background art, the present invention discloses a medicine bottle installation and detection structure, which has the following beneficial effects:

[0086] First, this invention fundamentally changes the detection method by setting up a non-contact installation detection unit 2. The sensor kit 22 physically isolates the infrared sensor 21 from the medicine bottle installation space, so that the detection process does not require direct contact with the medicine bottle. This effectively avoids contamination of sensor contacts or circuits by leakage or crystallization of hypertonic contrast agents, thereby significantly improving the long-term reliability and stability of the detection and solving the problems of detection failure and subsequent cleaning caused by sensor damage.

[0087] Secondly, the medicine bottle installation and detection structure integrates a rotating anti-leakage mechanism 3. This mechanism can drive the medicine bottle mounting base 1 to rotate and switch from a vertical working position to a horizontal bottle removal position. When the medicine bottle is removed in a horizontal position, gravity can be used to keep the residual medicine inside the bottle away from the puncture needle interface area, which greatly reduces the risk of medicine leakage from the puncture needle, reduces medicine waste, and keeps the operating environment clean.

[0088] Third, a gravity sensor is installed on the vial mounting base 1, which can detect changes in the weight of the vial in real time. By monitoring the weight decay during the aspiration process and comparing it with a pre-stored threshold, the system can automatically and accurately determine whether the medication in the vial is about to be completely drawn. This avoids the situation where air is drawn in due to the medication being completely drawn out, reduces unnecessary venting operations, and improves the efficiency and automation level of the injection process.

[0089] This invention systematically solves three major industry pain points—easy failure of medicine bottle detection, easy leakage when removing the bottle, and difficulty in judging the remaining amount—through an integrated structural design that combines non-contact installation detection, rotational leak prevention, and gravity sensing detection. It significantly improves the reliability, operational safety, and intelligence level of high-pressure injection devices.

[0090] To further optimize the implementation effect of the present invention, in some other embodiments, the remaining technical features are the same, the difference being that, for example... Figure 6-7 As shown, the medicine bottle mounting base 1 includes: a base body 11, a bottle holder 12, and two side plates 13 located on the outside of the bottle holder 12. The side plates 13 are used to wrap around and fix the medicine bottle from the side.

[0091] Using the preferred embodiment described above, the bottle holder 12 is fixed above the base 11 with screws, and its curved surface matches the bottom contour of the medicine bottle. Two side plates 13 are respectively installed on top of the bottle holder 12 of the medicine bottle mounting base. The side plates 13 are consistent with the curvature of the upper part of the bottle holder 12. After the side plates 13 are installed, they can wrap the medicine bottle to a greater than 270°, which can firmly fix the medicine bottle inside the medicine bottle base. When the equipment is pushed, the medicine bottle will not shake, which may cause the medicine bottle to become loose from the puncture device.

[0092] Furthermore, based on the above embodiment, the side plate 13 is provided with a bottle clamping part 131, which extends inclinedly toward the center of the bottle holder 12 and can undergo elastic deformation to change the angle between itself and the side plate 13, thereby clamping the medicine bottle.

[0093] Using the preferred embodiment described above, an independent, elastically deformable bottle-clamping portion 131 is provided at the center of the inner side of each side plate 13. Its root is connected to the main body of the side plate 13, and the entire portion extends pre-tilted towards the center of the bottle holder 12. When the medicine bottle is placed in and the side plate 13 is closed, the outer wall of the medicine bottle compresses the bottle-clamping portion 131, causing it to elastically deform and generating a continuous clamping force pointing towards the center of the medicine bottle. This allows the structure to adapt to minute tolerances in the diameter of the medicine bottle and provides a more reliable fixation than a simple rigid enclosure.

[0094] By extending and deforming the bottle clamping part 131 at an angle, it can adapt to medicine bottles of different diameters and further fix the medicine bottles through elastic clamping force, solving the problem that traditional fixing structures can only adapt to a single size of medicine bottle and have insufficient clamping force. At the same time, the elastic deformation design avoids hard contact damage to the outer wall of the medicine bottle.

[0095] This device, through the adaptive deformation of the elastic bottle clamp 131, can flexibly accommodate various sizes of medicine bottles, such as 15mL, 50mL, 100mL, and 500mL. Whether it is a small-volume contrast agent bottle or a large-volume saline bottle, it can achieve stable fixation, reliable detection, and leak-proof bottle removal without the need to replace special installation parts, which greatly improves the versatility and adaptability of the device in diverse medical scenarios.

[0096] Furthermore, based on the above embodiment, the side plate 13 is provided with a hollow part 132, and the bottle clamping part 131 is a convex strip structure set at the position of the hollow part 132.

[0097] Using the preferred embodiment described above, the bottle clamping part 131 is designed as a convex-shaped strip structure, with the head of the "convex" shape serving as the clamping end and the neck as the elastic deformation area, and the entire structure is embedded within the hollow part 132. The convex-shaped structure ensures that the clamping end has sufficient width to distribute pressure and avoid damage to the medicine bottle label. Furthermore, hollow holes are also provided on the clamping end of the bottle clamping part 131.

[0098] The hollowed-out section 132 provides sufficient deformation space for the convex strip-shaped bottle clamping section 131, ensuring that the bottle clamping section 131 can stretch and contract flexibly and improve clamping reliability. The convex strip structure makes the bottle clamping section 131 more evenly stressed and the elastic recovery force stable. At the same time, the hollowed-out design reduces the overall weight of the side plate 13, optimizes the structural layout, and balances clamping effect with structural lightweighting.

[0099] To further optimize the implementation effect of the present invention, in some other embodiments, the remaining features are the same, except that the base 11 is provided with a puncture device fixing seat 111 for installing the puncture device 4, and a suction tube fixing seat 112 for fixing the suction tube; the suction tube fixing seat 112 is provided with a slot 114 for fixing the suction tube; the bubble sensor is set at the slot 114.

[0100] By adopting the above-mentioned preferred solution, the puncture device fixing seat 111 and the drug suction line fixing seat 112 are integrated on the seat body 11 to achieve integrated fixing of the puncture device and the drug suction line, reducing assembly errors caused by the scattered installation of components; the design of the slot 114 makes the drug suction line more securely fixed, avoiding the displacement of the line from affecting the accuracy of bubble detection. At the same time, the bubble sensor is set at the corresponding position of the slot 114, shortening the detection distance, improving the bubble recognition sensitivity, and timely avoiding the risk of bubbles entering the human body or affecting the injection effect.

[0101] In a preferred embodiment, the suction tubing fixing seat 112 is provided with a cylindrical circular protrusion 113. The circular protrusion 113 has a groove 114 for embedding the suction tubing. The two opposite sidewalls of the groove 114 are designed as arc-shaped walls protruding towards the center, thereby holding the tubing in place. To further enhance the fixing effect and prevent the tubing from sliding within the groove 114, multiple parallel grooves are provided on the inner surface of the arc-shaped wall to significantly increase the friction between it and the outer wall of the tubing.

[0102] Furthermore, the bottom of the circular protrusion 113 is connected to a micro-vibration module (not shown in the figure). When the system detects air bubbles in the tubing or to prevent air bubble accumulation, the micro-vibration module can be activated, causing the entire circular protrusion 113 and its groove 114 to generate high-frequency, low-amplitude mechanical vibration. This vibration is transmitted to the fixed drug suction tubing, effectively causing tiny air bubbles attached to the tubing wall or suspended in the drug solution to break up, merge, and float to the venting point, thereby achieving an auxiliary defoaming function and further improving the quality and safety of tubing preparation before injection.

[0103] To further optimize the implementation effect of the present invention, in some other embodiments, the remaining technical features are the same, the difference being that, for example... Figure 8-11 As shown, the rotating leak-proof mechanism 3 includes:

[0104] Rotary fixing rod 31, which passes through the fixing hole at the lower part of the medicine bottle mounting base 1, is used to enable several medicine bottle mounting bases 1 to rotate independently around it.

[0105] Slide key 32, slide key 32 is movably set in the vertical direction;

[0106] The slide key fixing plate 33 is installed on the equipment base and is used to install the slide key 32;

[0107] Longitudinal elastic element 34 (e.g., longitudinal spring) is connected between the equipment base and the slide key fixing plate 33 to provide a reset elastic force for the slide key 32.

[0108] The fixing buckle 35 is movable in the horizontal direction and has a fixing terminal 351 on its side;

[0109] The retaining cover 36 is used to accommodate the retaining buckle 35.

[0110] A transverse elastic element 37 (e.g., a transverse spring) is connected between the fixing buckle 35 and the inner wall of the fixing buckle cover 36.

[0111] Among them, the sliding key fixing plate 33 is provided with a wedge-shaped protrusion 331, and the fixing buckle 35 is provided with a sloping groove 352 that cooperates with the wedge-shaped protrusion 331. The sloping surface of the wedge-shaped protrusion 331 is connected to the sloping surface of the sloping groove 352.

[0112] The medicine bottle mounting base 1 is provided with a slot 14 that mates with the fixed terminal 351;

[0113] The up-and-down movement of the slide key 32 can drive the fixing buckle 35 to move horizontally against the elastic force of the transverse elastic element 37 through the wedge-shaped protrusion 331 and the inclined surface of the inclined groove 352, so that the fixing terminal 351 can be inserted into or removed from the slot 14 of the medicine bottle mounting base 1, thereby realizing the locking or unlocking of the medicine bottle mounting base 1 and the equipment base; after unlocking, the medicine bottle mounting base 1 can rotate around the rotating fixing rod 31 to the horizontal bottle removal position.

[0114] Using the preferred scheme described above, when the slide key 32 is pressed, it causes the slide key fixing plate 33 to move downwards. The protruding inclined surface drives the fixing buckle 35 to compress the transverse spring and retract inwards, causing the fixing terminal 351 on its side to exit from the slot 14 on the current medicine bottle mounting base 11, thus unlocking the device. At this time, the medicine bottle mounting base 1 can be manually rotated outwards by approximately 90 degrees to a horizontal position. After releasing the slide key 32, the longitudinal spring resets it, the protrusion retracts, the transverse spring pushes the fixing buckle 35 back to its original position, and the terminal extends out in preparation for the next locking action.

[0115] The simple up-and-down movement of the slide key 32 reliably converts to the horizontal locking / unlocking movement of the fixed buckle 35 via the inclined plane mechanism, achieving one-button operation and providing a good user experience. The self-locking mechanism utilizes the restoring force of the elastic element to ensure the stable locking of the medicine bottle mounting base 1 in the vertical working position, preventing accidental rotation. Integrating multiple functional components (slide key 32, fixed buckle 35, elastic element) into a single linkage mechanism maximizes space utilization.

[0116] To further optimize the implementation effect of the present invention, in some other embodiments, the remaining technical features are the same, the difference being that, for example... Figure 12 As shown, three vial mounting assemblies a (e.g., pre-filled with saline, contrast agent A, and contrast agent B from left to right) are mounted side-by-side on the equipment base via the same rotating fixing rod 31 and can rotate independently.

[0117] Using the preferred scheme described above, multiple sets of vial mounting components a are arranged side-by-side via the same rotating fixing rod 31. This optimizes the structural layout of the multi-vial mounting system, reduces space occupation, and allows each vial mounting base 1 to rotate independently and be controlled individually. During operation, medical personnel can press down the sliding key 32 of the corresponding vial individually to rotate it to a horizontal position for replacement or removal, without affecting the other two vials that are in a vertical working state. This greatly improves the operational flexibility when continuously injecting or replacing multiple vials.

[0118] To further optimize the implementation effect of the present invention, in some other embodiments, the remaining features are the same, except that the sensor kit 22 is a transparent acrylic cover.

[0119] By adopting the above-mentioned preferred solution, a transparent acrylic cover is used as the sensor kit 22. On the one hand, it can penetrate the infrared signal without obstruction, ensuring the accuracy of non-contact detection and avoiding detection misjudgment caused by signal attenuation. On the other hand, the acrylic cover achieves physical isolation between the infrared sensor 21 and the medicine bottle installation space, completely blocking the contrast agent leakage path and preventing the sensor or circuit board from being contaminated or damaged. At the same time, the acrylic cover material is resistant to contrast agent corrosion and easy to clean, reducing equipment maintenance costs.

[0120] In addition, such as Figure 13 As shown, this invention discloses a method for detecting the installation of medicine bottles, applicable to any of the above-mentioned medicine bottle installation detection structures, comprising:

[0121] The infrared sensor 21, located at the bottle opening of the medicine bottle mounting base 1 and isolated by the sensor kit 22, detects whether the medicine bottle is installed in place in a non-contact manner.

[0122] When the medicine bottle is detected to be installed in place, the automatic drug suction program is triggered. The main control board drives the injection motor to draw the medicine liquid from the medicine bottle through the puncture device.

[0123] During the drug inhalation process, the drug inhalation tubing is monitored in real time by a bubble sensor, and the drug inhalation is stopped when a bubble is detected.

[0124] The weight information of the medicine bottle is obtained in real time by gravity sensor and compared with the pre-stored empty bottle weight threshold corresponding to the medicine bottle specification. When the weight information is close to or reaches the empty bottle weight threshold, it is determined that the medicine liquid in the medicine bottle has been completely drawn.

[0125] When it is necessary to remove the medicine bottle, control the rotating anti-leakage mechanism 3 to rotate the medicine bottle mounting base 1 to the horizontal bottle removal position, and then remove the medicine bottle.

[0126] This invention discloses a method for detecting the installation of medicine bottles. After the medicine bottle is installed on the medicine bottle holder, an infrared sensor 21 detects the installation in place signal and sends this signal to the main control board. Upon receiving the installation in place signal, the main control board can automatically control the motor to perform the medicine suction function. During the suction process, a bubble sensor can monitor the bubble detection status in the suction tube in real time. When bubbles are detected in the tube during the suction process, the main control board will automatically control the system to stop suction to avoid sucking in too many bubbles, which would result in low exhaust efficiency. The dual sensor detection of medicine bottle installation in place and bubble sensor can realize the automatic control function of the system, which greatly facilitates the operator's operation of the equipment. The entire suction and exhaust process can be completed automatically without the operator's intervention, and the efficiency of equipment use can be improved.

[0127] This method integrates non-contact detection, automatic drug aspiration, bubble monitoring, remaining volume assessment, and leak-proof bottle removal in an orderly manner, so that the entire injection preparation process does not require manual judgment and operation, which greatly improves the efficiency, standardization and safety of medical operations and reduces the risks caused by differences in operator experience.

[0128] Furthermore, before acquiring the weight information of the medicine bottle in real time through the gravity sensor, the process also includes: acquiring the specification information of the medicine bottle (including the brand, production batch number, capacity, etc.) through the barcode scanning module, and retrieving the pre-stored full bottle weight threshold and empty bottle weight threshold for the corresponding specification based on the specification information.

[0129] By adopting the above-mentioned preferred solution, the bottle specifications are obtained through the barcode scanning module and the corresponding weight threshold is retrieved, thus solving the judgment error problem caused by the weight difference of different bottle specifications. The pre-stored full / empty bottle weight threshold is used as the judgment benchmark, making the detection of the remaining liquid volume by the gravity sensor more accurate. This avoids incomplete or excessive aspiration of medicine due to unclear bottle specifications, further improving the reliability of automatic control, reducing liquid waste and ineffective equipment operation, and avoiding unnecessary operations during the aspiration process, which may cause air bubbles to enter the tubing or syringe, requiring venting, thereby reducing the efficiency of the equipment and causing liquid waste during the venting process.

[0130] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
