Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to an intelligent cleaning infusion port. Background Art

[0002] The intravenous infusion port provides supportive treatment by intravenously infusing drugs and nutrients. It can reduce the pain and difficulty of repeated venipunctures, prevent irritating drugs from damaging peripheral veins, has an aesthetically pleasing appearance, does not require dressing changes, and does not affect the wearer's bathing. It is widely used in the treatment of cancer.

[0003] The device is implanted in the body and cannot be cleaned directly. Existing cleaning techniques require a pulsed flushing technique, which involves rhythmically pushing the syringe piston (push-stop-push-stop), injecting 1ml at a time, with intervals of 0.8-1 second. This creates turbulent flow and eddies within the infusion station, ensuring a thorough cleansing of the inner walls of the station and the catheter.

[0004] In practice, this method may have a certain cleaning effect on the catheter wall, but it cannot achieve an ideal cleaning effect on the inner wall of the injection seat. The main reason is that manual operation is affected by the operator's physical, emotional, psychological and other factors, and cannot be truly precise. Therefore, when the injection volume is insufficient or the rhythm is not properly grasped, it is difficult to form a vortex effect with sufficient pressure; on the other hand, from a structural point of view, the inner diameter of the injection seat is about 25mm, the height is more than 15mm, and its volume reaches more than 8kml. With a push volume of 1ml, it is difficult to achieve a complete flushing of the inner wall of the injection seat; in addition, the injection seat and the catheter have a huge size gap. The inner diameter of the injection seat is 25, and the catheter is usually 1.4. It is difficult to achieve simultaneous cleaning of both through water flow.

[0005] Therefore, in clinical practice, even if the inner wall of the injection seat is professionally cleaned, there are still residual drugs. When the next injection is made, multiple drugs may be mixed together, or the same drug may be mixed twice. Due to the inconsistency of the efficacy of the previous and subsequent drugs, the result may be reduced efficacy and medication risks, especially when the previous drug has expired, which may cause a safety accident.

[0006] Therefore, it is necessary for those skilled in the art to propose a new infusion port to solve this problem, so that the entire interior of the infusion port can be thoroughly and effectively cleaned, thereby reducing the safety risks of patients and helping to reduce the workload of operating nursing staff. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an intelligent cleaning infusion port, which can intelligently clean the inner wall of the injection seat and the catheter wall without manually adjusting the liquid pushing rhythm, so as to solve the problem that the existing technology cannot effectively clean the inner wall of the injection seat and there is a risk of mixing of the front and back drugs.

The processing chip is electrically connected to the micromotor and the electromagnetic control valve, and the processing chip is wirelessly connected to the external controller. The rotating shaft is flexibly connected to the hemisphere above the main shaft of the micromotor through the flexible body, so that during the rotation process, there is a certain angle of deflection and swing, which is beneficial to the disturbance of the liquid flow and the formation of eddy currents and turbulence.

[0010] More preferably, a connecting groove is provided at the center of the rotating shaft, the mouth of the connecting groove matches the outer surface of the hemisphere so that the two can move relative to each other, and the flexible body is a silicone spring provided in the connecting groove.

[0011] More preferably, the stirring blade has a tile-like shape and is arranged at an angle of 10-20 degrees to the radial direction of the rotating shaft.

[0012] More preferably, a battery accommodating cavity and a battery cover are provided at the bottom of the base plate.

[0016] More preferably, a high-definition camera and a position sensor are provided on the inner wall of the injection seat, and both the high-definition camera and the position sensor are electrically connected to the processing chip.

[0017] More preferably, the external controller is provided with a display screen and control buttons.

[0018] The beneficial effects of the present invention are:

[0019] The present invention drives the stirring blade to rotate by a micro motor, thereby driving the cleaning liquid to clean the inner wall of the injection seat. In order to achieve the purpose of further cleaning, the electromagnetic control valve can be closed to gradually increase the amount of cleaning liquid, further expand the height range of cleaning, and achieve the purpose of comprehensively cleaning the inner wall of the injection seat; and in this embodiment, through the flexible connection between the flexible body and the hemisphere arranged above the main shaft of the micro motor, the rotating shaft has a certain angle of deflection and swing during the rotation process, which is beneficial to the disturbance of the liquid flow, and finally forms eddy currents and turbulence, thereby enhancing the flushing force and improving the cleaning effect; at the same time, when the catheter needs to be cleaned, the rotation speed can be reduced, and the electromagnetic control valve can be slowly opened, and the cleaning liquid enters the catheter and cleans the guide wall Cleaning is carried out; in addition, the present invention also controls the micro motor and the electromagnetic control valve through wireless communication between the external controller of the control component and the functional components of the injection seat, thereby realizing monitoring and management of the cleaning process, achieving the purpose of intelligent operation, and making the operation very simple. It is only necessary to inject an appropriate amount of cleaning liquid. The rest of the work is completed by the device itself, and the pressure can be properly controlled to avoid being too light and failing to achieve the cleaning effect, and to avoid being too heavy and causing impact on the catheter and veins. Compared with the existing technology, the inner wall of the injection seat can be fully cleaned, and the catheter wall can also be cleaned, thereby realizing comprehensive and intelligent cleaning, making the cleaning thorough and complete, saving operating labor and improving work efficiency.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] In the above description of the present invention, it should be noted that the terms "one side," "the other side," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0032] like Figure 1-5 As shown, this embodiment provides an intelligent cleaning infusion port, including an injection seat 1 and a catheter 2. In particular, this embodiment also includes a cleaning component and a control component. The cleaning component cleans the injection seat and the inner wall of the catheter, while the control component is used to intelligently control the cleaning operation. Specifically:

[0033] The injection seat includes a bottom plate 3 and an outer cover 4. The outer cover is sealed above the bottom plate, and a accommodating cavity is formed inside the outer cover. An opening is provided at the top of the outer cover, and a sealed membrane 5 is provided at the opening for lossless needle injection without leakage. The cleaning component includes a micro motor 6 provided on the inner bottom plate of the outer cover, a hemisphere 7 fixedly provided above the main shaft of the micro motor, and a rotating shaft 8 slidingly provided above the hemisphere. The rotating shaft and the hemisphere are connected through a flexible body 9. The circumferential surface of the rotating shaft is evenly provided with stirring blades 10. Driven by the micro motor, the hemisphere rotates with it, and then drives the flexible body to rotate, thereby driving the rotating shaft to rotate, and then drives the stirring blades to rotate, thereby stirring the cleaning liquid to form a flushing force. The flexible body and the hemisphere are not rigidly connected and have their own motion characteristics. Therefore, during the rotation process, they will deflect and swing at a certain angle, thereby enhancing the impact on the liquid flow, forming eddies and turbulence, and improving the flushing ability. The control component includes a processing chip 11 sealed in the bottom plate, an electromagnetic control valve 12 arranged in the catheter and an external controller 13 outside the human body. The processing chip is electrically connected to the micro motor and the electromagnetic control valve, and the processing chip is wirelessly connected to the external controller. The external controller sends instructions, and after receiving the instructions, the processing chip controls the start and stop of the micro motor and the electromagnetic control valve, thereby realizing the monitoring and management of the cleaning process and achieving the purpose of intelligent operation.

[0034] In this embodiment, a connecting groove 14 is provided at the center of the rotating shaft. The connecting groove is a cylindrical hole, and a certain arc-shaped contact surface is provided at the mouth of the connecting groove. The contact surface matches the outer surface of the hemisphere so that the two can move relative to each other, that is, providing freedom of axial rotation and radial movement. At the same time, the flexible body is a silicone spring, one end of which is provided in the connecting groove and the other end is provided on the sphere, thereby limiting the rotating shaft above the hemisphere with a certain degree of freedom in the axial direction.

[0035] During cleaning, the electromagnetic control valve is closed by an external controller to form an independent space inside the injection seat. A non-destructive injection needle is inserted into the injection seat. At this time, the camera takes pictures and displays them in real time on the display screen. The operator can push the injection needle to the appropriate position according to the display screen, then inject an appropriate amount of saline, start the micromotor, and under the drive of the micromotor, the hemisphere rotates, driving the flexible body to rotate, thereby driving the rotating shaft to rotate, and then driving the stirring blade to rotate, thereby stirring the saline to form a flushing force. Since the flexible body and the hemisphere are not rigidly connected and have their own motion characteristics, they will deflect and swing at a certain angle during the rotation process, thereby enhancing the impact on the liquid flow and forming eddies and turbulence. After flushing for a period of time, some saline can be added to continue cleaning until the inner wall of the injection seat is cleaned. At this time, the catheter is opened again, and saline is introduced into the catheter to clean the catheter wall. At this time, the cleaning component should continue to work to maintain a certain water pressure and improve the cleaning level of the catheter wall.

[0036] If the inner cavity of the injection seat is filled with liquid during the cleaning process, the electromagnetic control valve can be opened to release the liquid and discharge part of the mixed liquid to facilitate the injection of new saline.

[0037] In this embodiment, a pressure sensor 15 can also be set on the catheter wall. The pressure sensor is electrically connected to the processing chip and transmits information via Bluetooth, allowing the operator to grasp the liquid pressure in the tube and accurately monitor the cleaning pressure to prevent excessive pressure from damaging the catheter.

[0038] As a further improvement of this embodiment, the stirring blade has a tile-like shape, that is, a streamlined arc is provided inside, which is conducive to the outflow of the cleaning liquid. At the same time, in order to further improve the liquid flow through capacity to form a greater flow velocity, and to consider the proportional relationship between the height and width dimensions (i.e., diameter) of the injection seat itself, the inventor has conducted repeated experiments and believes that when the installation orientation of the blade is set at an angle of 10-20 degrees to the radial direction of the rotating shaft, significant vortex and turbulence characteristics can be achieved, and the cleaning effect is better.

[0039] As a further improvement of this embodiment, a battery accommodating cavity 16 and a battery cover 17 are provided at the bottom of the base plate. The battery accommodating cavity can hold multiple disposable batteries. The batteries are connected to various functional components through wires to provide electrical energy. After installation, the battery cover is used for sealing.

[0040] As a further improvement of this embodiment, a chip receiving cavity 18 and a chip cover 19 are provided at the bottom of the base plate.

[0041] As a further improvement of this embodiment, the bottom plate is provided with a sealing film 20 at each cover to completely isolate the chip and battery from the outside.

[0042] As a further improvement of this embodiment, the rotating shaft and the stirring blades are both made of silicone, which has good affinity and high deformation ability, thereby realizing the disturbance of the cleaning liquid, increasing the volatility, and achieving the effects of vortex and turbulence.

[0043] As a further improvement to this embodiment, a high-definition camera 21 and a position sensor 22 are mounted on the inner wall of the injection seat, both of which are electrically connected to the processing chip. The high-definition camera monitors the insertion position of the injection needle, facilitating direction adjustment for more precise injections. It also allows for on-the-spot control of the injection depth, preventing excessive penetration into the rotating shaft and potentially causing misoperation.

[0044] As a further improvement to this embodiment, the external controller is provided with a display screen 23 and control buttons 24. The display screen can display the parameters of each functional component, thereby more accurately understanding the operating status. At the same time, it can also display camera information, allowing accurate grasp of internal information, which helps external operators take appropriate measures in real time to respond appropriately.

[0045] In this embodiment, the micro motor is a DC motor, which is directly connected to the battery to provide driving power, thereby reducing the number of parts.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
