In an embodiment of the invention, the safety smart high pressure injector can be used for injecting contrast media into a patient.

The following describes in detail, by way of specific embodiments, the safety intelligent high pressure injector provided in the embodiments of the present application with reference to fig. 1 to 3.

Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a safe and intelligent high-pressure injector according to an embodiment of the invention; FIG. 2 is a schematic view of a part of a safety intelligent high-pressure injector according to an embodiment of the present invention; fig. 3 is a schematic structural diagram of a pressure regulating assembly of a safety intelligent high-pressure injector according to an embodiment of the present invention. The safety intelligent high-pressure injector 100 according to one embodiment of the present invention includes a housing 10, a transfusion tube, a main control panel (not shown), a bubble sensing device 30, and a loading assembly 40.

A fixing device 11 is provided on the housing 10, wherein the fixing device 11 may be located above the housing 10, and the fixing device 11 is used for fixing the medicine bottle 20, so that the medicine bottle 20 is located at a higher position, and the medicine liquid is convenient to transfer. The vial 20 may store a drug solution such as a contrast medium or physiological saline. A plurality of fixing devices 11 may be provided on the housing 10 for fixing different vials 20, respectively, and contrast medium and physiological saline are stored in the vials 20, respectively. When the infusion tube is used for transporting the liquid medicine, the contrast agent and the physiological saline which are respectively stored in each liquid medicine can be mixed so as to adjust the concentration and the viscosity of the contrast agent. By such arrangement, mixing with physiological saline can reduce the concentration of the contrast agent, making it easier for the drug to be injected into the body and spread to the area to be imaged. Such dilution may also reduce patient discomfort during injection and reduce irritation to blood vessels and tissues. In addition, the physiological saline is used as a physiological fluid which is more similar to the physiological environment of a human body, so that the mixed injection fluid is more in line with the physiological characteristics of the human body. In addition, mixing the contrast agent and physiological saline also helps to reduce possible adverse reactions. Some patients may be allergic or intolerant to pure contrast agents, but by mixing with normal saline, the risk of allergy to the patient can be reduced and the safety of the treatment improved.

With respect to the above-mentioned infusion tube, the infusion tube may include a plurality of branch pipes and a main pipe, the plurality of branch pipes are connected to the main pipe, and the plurality of branch pipes are connected to different vials 20, respectively, so as to transport different medical liquids (physiological saline or contrast agent, etc.) into the main pipe for mixing, and inject into the human body through the main pipe.

Regarding the above-mentioned main control board, the main control board is an electronic device for controlling and managing operations of other devices. In high pressure injectors, a main control board is designed to control and monitor various functions and parameters of the injector. The main control board is usually composed of a microprocessor, a memory, an input/output interface, a power management and other components. It serves as a core component of the injector and is responsible for coordinating and controlling the individual operations of the injector. The main control board can be used for controlling injection parameters, detecting injection process, controlling medicine liquid conveying and the like. The main control board allows a user to set and adjust parameters such as injection speed, pressure, volume and the like of the injector so as to meet specific injection requirements. It ensures that the drug is injected at a precise and consistent rate, thereby providing a stable therapeutic effect. The main control board monitors parameters such as pressure, flow, volume and the like in the injector through the sensor and the circuit. The system can monitor and record the working state of the injector in real time so as to ensure the normal operation of the injector and provide accurate data for subsequent analysis and recording. The main control board is responsible for controlling the injection liquid delivery of the injector, and ensures that the medicines are injected in preset dosage, speed and sequence. It can coordinate the driving components of the injector, such as motor, valve, etc., to achieve accurate delivery.

The main control boards are respectively and electrically connected with the bubble sensing devices 30. The bubble sensing means 30 is a sensor for detecting bubbles in the medical fluid. Through the electric connection with the main control board, the bubble sensing device 30 can transmit the detected bubble information to the main control board. This enables the master board to timely sense the presence of bubbles and perform corresponding processing. When the air bubble is detected by the bubble sensing device 30, the main control board receives a signal from the sensor. Through the electrical connection, the main control board can analyze the signal and trigger a corresponding alarm or exception handling procedure. This helps to find out in time a bubble problem in the syringe and alerts the operator to take appropriate action. The main control board can record the data and display or save the related information according to the requirement. This allows tracking and recording of the operating state of the injector, the time and frequency of occurrence of bubble events, and quality control of the injection process. It should be noted that, the main control board may interact with the bubble sensing device 30, and perform corresponding control according to the signal of the sensing device. For example, when the bubble sensing device 30 detects bubbles, the main control board may send instructions to stop or adjust the operation of the safety smart high pressure syringe 100 to ensure the safety and therapeutic effect of the patient. Through the arrangement, the main control board can timely sense the existence of bubbles and take corresponding control and treatment measures. This helps to improve the safety of the injection, reduces the risk that the patient may face, and ensures proper operation of the injector.

In addition, in this embodiment, the main control board is electrically connected with the loading assembly 40, the infusion tube can be loaded in the loading assembly 40, the tube wall of the infusion tube is respectively contacted with the loading assembly 40 and the inner wall of the housing 10, the loading assembly 40 is controlled to rotate by the main control board, and at this time, the loading assembly 40 and the inner wall of the housing 10 can jointly extrude the tube wall of the infusion tube, so that air bubbles in the infusion tube can be extruded back into the medicine bottle 20. By such arrangement, the air bubbles in the infusion tube can be detected by the air bubble sensing device 30, and the loading assembly 40 is controlled to rotate on the housing 10 by the main control board so as to discharge the air bubbles in the infusion tube.

The infusion tube is mounted on the housing 10, a portion of the infusion tube is mounted in the mounting groove 12, and a portion of the infusion tube is mounted in the loading assembly 40. Wherein, specifically, two ends of the infusion tube are arranged in the mounting groove 12, and the infusion tube at the middle part is arranged in the loading assembly 40.

In some embodiments, the loading assembly 40 includes a first rotary wheel 41 and a first motor, the first motor and the first rotary wheel 41 being coupled; the shell 10 is provided with a loading groove 13, and the loading groove 13 is communicated with the mounting groove 12; the first rotating wheel 41 is rotatably disposed in the loading slot 13.

The first motor can control the first rotating wheel 41 to rotate, and a loading groove 13 is formed in the shell 10, the loading groove 13 and the mounting groove 12 are communicated with each other, and the infusion tube can be mounted on the loading groove 13 and the mounting groove 12. When the infusion tube is required to be placed on the loading assembly 40, the first motor is started to drive the first rotary wheel 41 to rotate so as to apply friction force to the infusion tube, so that the infusion tube can be loaded in the loading groove 13, and the infusion tube can be installed in place in the loading assembly 40 through the friction force of the first rotary wheel 41.

Specifically, if the tube is not in place, the first wheel 41 still imparts friction to the tube when rotated to cause movement of the tube to adjust its position on the loading assembly 40; when the infusion tube is in place, the first rotating wheel 41 does not rub against the infusion tube when rotated.

In some embodiments, the loading assembly 40 further includes a second rotary wheel 42 and a second motor coupled to the second rotary wheel 42; the shell 10 is also provided with a fixed groove 14, and the fixed groove 14 is communicated with the mounting groove 12; the second rotating wheel 42 is rotatably disposed in the fixed slot 14, and a part of the infusion tube is disposed between the second rotating wheel 42 and the slot wall of the fixed slot 14.

The loading assembly 40 further includes a second rotatable wheel 42 and a second motor coupled to the second rotatable wheel 42, the second motor being operable to control rotation of the second rotatable wheel 42. The housing 10 is provided with a fixing groove 14, and the second rotary wheel 42 is mounted in the fixing groove 14. When loading the infusion tube, the second rotating wheel 42 can cooperate with the first rotating wheel 41 to load the infusion tube. When the first rotating wheel 41 rotates to push the infusion tube to be mounted in the fixed groove 14, the second motor can be started, and the second rotating wheel 42 can slowly rotate at the moment, so that friction force is applied to the infusion tube to enable the infusion tube to enter between the second rotating wheel 42 and the groove wall of the fixed groove 14. With this arrangement, the first swivel wheel 41 can be engaged to confirm that the infusion tube is in place on the loading assembly 40.

And, the second rotary wheel 42 is capable of rotating to squeeze the infusion tube, thereby squeezing the air bubbles within the infusion tube back into the vial 20. Specifically, when the second rotatable wheel 42 is rotated, the tubing can be squeezed, thereby preventing further forward transport of the air bubbles, which are forced toward the vial 20 until completely inside the vial 20. The state and position of the bubble can be detected by corresponding monitoring and control means during the extrusion process. This may be achieved by a sensor, trigger signal or other monitoring means.

In some other examples, the second rotating wheel 42 may also push contrast media within the infusion tube to move, increasing the rate of contrast media delivery. In the safety intelligent high-pressure syringe 100, the syringe and the infusion tube are communicated, and by disposing the infusion tube in the fixed groove 14, the second rotating wheel 42 and the fixed groove 14 are abutted against the infusion tube together, and when the second rotating wheel 42 rotates, the second rotating wheel 42 gives forward thrust to the contrast agent in the infusion tube through the outside of the infusion tube. With this arrangement, the second rotating wheel 42 can press the infusion tube when rotating, thereby pushing the contrast medium in the infusion tube to move and improving the conveying speed of the contrast medium.

In some embodiments, the second rotating wheels 42 are disposed in a plurality, and the rotating wheels are circularly distributed in the fixed slot 14. The plurality of second rotating wheels 42 which synchronously rotate can simultaneously squeeze different parts on the infusion tube, so that on one hand, bubbles can be pressurized, bubbles are prevented from continuously moving along with the infusion tube, and bubbles in liquid medicine are further eliminated; on the other hand, the transmission speed of the contrast agent in the infusion tube can be further improved.

The second rotating wheels 42 are distributed circularly, and the fixed slot 14 is circular.

In some embodiments, the loading assembly 40 further includes a laser sensor 43, a mounting hole is formed in an end of the mounting groove 12 near the loading groove 13, the laser sensor 43 is accommodated in the mounting hole, and the laser sensor 43 is electrically connected to the main control board.

A mounting hole is formed in a side of the mounting groove 12 adjacent to the loading groove 13, and a laser sensor 43 is mounted on the mounting hole. The laser sensor 43 may be used to detect if the infusion tube is properly installed in place to ensure the safety and accuracy of the infusion process.

Specifically, the laser sensor 43 may operate by emitting a laser beam and receiving a reflected light signal. When the infusion tube is correctly mounted in the loading groove 13, the infusion tube is opposite to the mounting hole, the light beam is reflected back by the infusion tube, and the laser sensor 43 receives the reflected light signal to judge that the infusion tube is mounted in place.

It should be noted that the laser sensor 43 typically emits a visible laser beam that can be used to locate the correct mounting position of the infusion tube. The light beam can be emitted in a straight line or in a scanning manner, and the position and angle of the light beam can also be adjusted to adapt to infusion tubes of different types and sizes. When the laser sensor 43 receives the reflected light signal, the light signal is converted into an electrical signal by an internal photoelectric element. These electrical signals are transmitted to the main control board for further processing and judgment. The laser sensor 43 is used to ensure that the tubing is properly installed to avoid possible leaks or infusion errors. When the laser sensor 43 detects that the infusion tube is not properly installed, the main control board may trigger an alarm or prevent an injection operation to ensure the safety and accuracy of the medical operation.

In some embodiments, the safety smart high pressure syringe 100 further includes a bubble sensor 44, the bubble sensor 44 being disposed on a side of the bubble sensor 44 that is disposed proximate to the vial 20 of the mounting groove 12.

Bubble sensor 44 is typically a non-contact sensor that detects and senses bubbles in a liquid by sensing principles such as optics, pressure, or vibration. The bubble sensor 44 is electrically connected with the main control board, and the bubble sensor 44 is electrically connected with the main control board, so that the bubble information sensed by the bubble sensor 44 can be transmitted to the main control board for subsequent processing and control. The bubble sensor 44 is capable of sensing the presence and quantity of bubbles by monitoring the condition of bubbles in the tubing during the flow of liquid. According to the preset threshold, the main control board can judge whether the bubble content in the infusion tube exceeds the safety range according to the feedback of the bubble sensor 44. When the content of the air bubbles exceeds the threshold value, the safe intelligent high-pressure injector 100 is closed, the injection of the liquid medicine to the human body is stopped, the safety of a patient is ensured, and the second motor is started to drive the second rotating wheel 42 to rotate, so that the air bubbles are extruded into the liquid medicine; when the bubble content does not exceed the threshold value, the second rotary wheel 42 may be turned off.

When the air bubble is completely squeezed back into the vial 20 by the loading device, the air bubble sensor 44 may signal or indicate the completion of the squeezing process. The bubble sensor 44 is electrically connected to the main control board, and can transmit the bubble state in the infusion tube detected by the bubble sensor 44 to the main control board.

Wherein a bubble sensor 44 is mounted in the mounting groove 12 on a side adjacent to the vial 20 by detecting the amount of air bubbles that are pushed back into the vial 20. When there is also a bubble in the tube, the bubble will move within the tube toward the vial 20 to be monitored by the bubble sensor 44; when there is no bubble in the tube, the bubble sensor 44 located near the vial 20 detects no bubble. Through the arrangement, whether the infusion tube also contains bubbles or not can be ensured. Preventing air bubbles elsewhere in the tubing from being undetected and making false decisions, which may result in the second rotator wheel 42 being turned off to squeeze the tubing.

In some embodiments, a first pressure sensor 50 is further included, the first pressure sensor 50 being disposed within the mounting groove 12 and in contact with the infusion tube.

Wherein, the first pressure sensor 50 is installed in the installation groove 12, and when the infusion tube is installed in the installation groove 12, the first pressure sensor 50 can be contacted with the infusion tube. Therefore, the pressure change in the infusion tube can be directly sensed, and the information is transmitted to the main control board for processing and analysis.

The first pressure sensor 50 is electrically connected to the main control board by a cable or other suitable means. The electrical connection allows the first pressure sensor 50 to transmit the detected pressure signal to the main control board so that the main control board can monitor and control the injection process of the liquid medicine in time. After receiving the pressure signal from the first pressure sensor 50, the main control board analyzes and processes the signal through an internal processing algorithm. The main control board can judge whether the pressure in the infusion tube exceeds the safety range according to the preset pressure range, and adopts corresponding control measures, such as adjusting the injection speed or stopping injection, according to the needs so as to ensure the safety and the accuracy of the injection of the liquid medicine.

The first pressure sensor 50 detects the pressure in the infusion tube by using different principles such as piezoresistance, piezoelectricity or compressed air. For example, the piezoresistive first pressure sensor 50 senses pressure changes by monitoring resistance changes; the piezoelectric first pressure sensor 50 converts pressure into an electrical signal by using a piezoelectric effect; the compressed air type first pressure sensor 50 senses the pressure change by measuring the compression degree of the compressed air.

Wherein the second pressure sensor 162 employs piezoresistive, piezoelectric, or other principles to sense pressure changes from the cover plate 16. For example, piezoresistive pressure sensors can sense pressure changes by monitoring resistance changes; piezoelectric pressure sensors utilize the piezoelectric effect to convert pressure into an electrical signal. The second pressure sensor 162 transmits this information to the main control board for processing and analysis by sensing pressure changes from the cover plate 16. The main control board can judge whether the connection between the cover plate 16 and the bottom shell 15 is tight or not according to a preset pressure range, and take corresponding control measures such as alarm or automatically adjust the rotation connection structure according to the need so as to ensure the tight connection. By such an arrangement, the pressure change between the cover plate 16 and the bottom case 15 can be monitored in real time.
