Description

Technical Field

[0001] The present invention relates to the technical field of injection, in particular to an auxiliary device used in conjunction with a rotary medicine-inhaling syringe. Background Art

[0002] Many diseases require the regular and quantitative administration of therapeutic agents, typically administered via syringe. Traditional syringes have needles, which inject medications, but the presence of these needles can cause pain and other discomfort to patients. The recent emergence of needle-free syringes has alleviated the pain associated with needle-assisted injections. Whether using a needle-assisted or needle-free syringe, effective management and control of the administration of therapeutic agents, such as strict control of the injection dose and timing, are crucial for patients requiring long-term injections.

[0003] However, currently available syringes generally only have drug injection functions and simple drug dosage display functions. Therefore, when users use ordinary needle-mounted and needle-free syringes for injection, they need to manually record the injection dosage and injection time for each injection, which makes it impossible to achieve effective medication management.

[0004] Therefore, there is an urgent need for a device that can be used with a syringe to achieve drug administration. Summary of the Invention

[0054] The auxiliary device for use with a rotary drug aspiration syringe of the present invention will be described in detail below with reference to the accompanying drawings. What is described herein is merely a preferred embodiment of the present invention, and those skilled in the art may conceive of other ways of implementing the present invention based on the preferred embodiment, which also fall within the scope of the present invention.

[0055] The directional terms appearing in the following detailed description, such as "front" and "back" are relative to the syringe. Specifically, "front" refers to the injection barrel side of the syringe, and "back" refers to the injection button side opposite to the injection barrel side.

[0056] The auxiliary device for use with a rotary drug-inhalation syringe of the present invention is applicable to both needle- and needle-free syringes, as long as the syringe is a commonly used syringe type that inhales drugs by rotation. For ease of description, the following describes the technical solution of the present invention using a rotary drug-inhalation needle-free syringe as an example.

[0057] Figure 1 The figure shows an existing rotary drug-inhaling syringe, which is a needle-free syringe. It was previously developed by the applicant and is also the general structure of most needle-free syringes on the market. The syringe generally comprises two parts that can rotate relative to each other and can move longitudinally relative to each other. The relative movement between the two parts realizes the functions of pressurization, drug inhalation and injection of the syringe. Figure 1 As shown, the syringe generally comprises a syringe front end portion 1, a syringe rear end portion 2, an injection tube 3 located at the front end of the syringe front end portion 1, and an injection button 4 located at the rear end of the syringe rear end portion 2, wherein a dose display window 5 is also provided on the syringe front end portion 1. When the syringe rear end portion 2 is rotated to inhale the drug, integer numbers corresponding to different doses will be displayed in sequence in the display window 5. In order to more accurately control the inhaled drug dose, the design of the internal structure of the syringe will achieve a noticeable sense of frustration at each dose unit value during the rotation of the syringe rear end portion 2 relative to the syringe front end portion 1, that is, the syringe will vibrate or feel a sense of frustration to the user's hand every time a different number is displayed in the display window 5. In this way, the user will not rotate (inhale) too much at one time, and can also more intuitively perceive the changes in the inhaled drug dose.

[0058] Figures 2A-2D Shown separately Figure 1 Various states of the syringe during use. Figure 2AFIG1 shows the initial state of the syringe before use. When the syringe needs to be used, the user can rotate the rear end portion 2 of the syringe in a first direction (e.g., clockwise). The rear end portion 2 of the syringe rotates relative to the front end portion 1 of the syringe and approaches the front end portion 1 of the syringe along the longitudinal axis of the syringe. The spiral pressurizing structure inside the syringe compresses the spring to accumulate energy for injection until the syringe reaches the position shown in FIG1 . Figure 2B The pressurization is completed as shown, and the injection button 4 will pop up. Figure 2C As shown, after the pressurization of the syringe is completed, the user can place the injection tube 3 of the syringe into the liquid medicine container, and rotate the rear end part 2 of the syringe in the second direction (such as counterclockwise) to move it away from the front end part 1 of the syringe along the longitudinal axis to draw the liquid medicine into the injection tube 3. During the drug absorption process, bubbles may be mixed in the liquid medicine. If bubbles or excess liquid medicine needs to be discharged, the rear end part 2 of the syringe can be rotated in the first direction to perform exhaust / liquid discharge operations. The user can repeat the above operations until the syringe absorbs the appropriate amount of medicine. When performing the injection operation, the user can press the injection button 4 to release the injection pressure accumulated during the pressurization process to complete the injection, as shown in FIG. Figure 2D shown.

[0059] In order to facilitate the management of the use of the syringe, the present invention provides an auxiliary device, which is independent of the syringe and can be installed and fixed on the syringe to cooperate with it. As mentioned above, the auxiliary device can also be used for a rotary drug-inhaling needle syringe. For example, Figure 1 The end of the injection tube 3 shown is provided with a needle.

[0060] According to the present invention, the auxiliary device 100 includes an injection control component capable of controlling the injection of the rotary drug-inhaling syringe and an intelligent component capable of calculating the inhaled drug dosage and recording the injection time.

[0061] Figures 3A-3C It is shown exemplarily in Figures 1 to 2D The auxiliary device 100 according to the present invention is installed in place on the rotary drug-inhaling syringe shown in FIG. Specifically, the auxiliary device 100 may include a rear end sleeve 130 that is sleeved on the syringe from the rear end portion 2 of the syringe and covers part of the front end portion 1 of the syringe. The rear end sleeve 130 is provided with an injection control component capable of controlling the injection of the rotary drug-inhaling syringe and an intelligent component capable of calculating the inhaled drug dose and recording the injection time. Figure 4As shown, the front side (left side in the figure) of the rear end sleeve 130 is an open end for receiving and holding the syringe rear end portion 2. The rear side of the rear end sleeve 130 is a closed end with an opening 131, and the opening 131 is used to set the injection control assembly. As shown in the figure, during use, the rear end sleeve 130 is assembled to the syringe rear end portion 2 of the rotary drug aspiration syringe, for example, by a tight fit, a snap connection, etc. In particular, the rear end sleeve 130 is sleeved on the syringe rear end portion 2 and can move with it. When the user uses the syringe to perform various operations, he only needs to operate the auxiliary device. For example, when the syringe is pressurized, the user only needs to rotate the rear end sleeve 130 relative to the syringe rear end portion 1. The sleeve 130 is also provided with a power supply for supplying power to the control device (for clarity, the power supply is not shown in the drawings). The power supply in the present invention can be a replaceable disposable battery or a rechargeable battery that can be recycled.

[0062] According to a preferred embodiment of the present invention, Figure 4 As shown, the rear end opening 131 of the rear end sleeve 130 is formed on the rear end wall of the sleeve and includes a groove 132 formed on the hole wall. Due to the formation of the groove 132, a front protrusion 133 and a rear protrusion 134 that are radially inwardly convex are formed at the front and rear parts of the rear end opening 131. The injection control assembly includes an additional injection button assembly arranged at the rear end opening 131 of the rear end sleeve 130. The additional injection button assembly includes an additional injection button 110 that is at least partially arranged in the opening 131 and a return spring 111 that is sleeved on the additional injection button 110 and placed in the groove 132 of the rear end opening 131. More specifically, as Figures 3A-3C As shown, the additional injection button 110 includes a hollow body 112 and a flange 113 located at the front of the body. The dimensions of the additional injection button 110 match those of the rear opening 131, such that the flange 113 of the additional injection button 110 is sized to fit within the recess 132 but is larger than the aperture defined by the front and rear raised portions 133, 134. The body 112 of the additional injection button 110 can freely move within a certain longitudinal range through the aperture defined by the rear raised portion 134. A return spring 111 is sleeved on the additional injection button 110, with its front end abutting against the rear wall of the flange 113 and its rear end abutting against the front wall of the rear raised portion 134.

[0063] During use, the rear sleeve 130 is fitted over the rear portion 2 of the syringe, and the injection button 4 at the rear end of the syringe rear portion 2 is positioned within the hollow body 112 of the additional injection button 110. This allows the additional injection button 110 and the injection button 4 to operate in sync. More specifically, in the initial state, the return spring 111 maintains the additional injection button 110 in a non-rebounded position. When the syringe is fully pressurized, the injection button 4 of the syringe rebounds, overcoming the force of the return spring 111 and causing the additional injection button 110 to rebound.

[0064] The intelligent component of the present invention includes a microcontroller unit (MCU) and a power supply for powering the auxiliary device (for clarity, the MCU and power supply are not shown in the accompanying drawings). The MCU in the present invention refers to a microcontroller, microcontroller unit, or single-chip microcomputer in the general sense familiar to those skilled in the art. It can be general-purpose or customized according to specific applications, and can be programmed to perform operations and logical judgments according to program instructions. The power supply in the present invention can be a replaceable disposable battery or a recyclable rechargeable battery. Of course, the present invention is not limited to this, and the intelligent component can also be connected to a power cord for external power supply. According to an embodiment of the present invention, the microcontroller unit may include a sensor device 125 disposed at the front end of the sleeve 130 and an intelligent component switch 120 disposed near the additional injection button 110 for controlling the operation of the sensor device 125. The sensor device 125 can be electronic or mechanical and is used to determine the syringe's drug aspiration and administration dosage by determining the movement of various parts of the syringe.

[0065] In a preferred embodiment, the sensor device 125 of the present invention is an electronic sensor device, which includes a laser sensor, such as a laser displacement sensor, a laser position sensor, etc. The laser sensor uses laser technology to perform measurements and can accurately measure changes in the position, displacement, etc. of the object being measured without contact. When the syringe completes pressurization, the injection button 4 of the syringe pops up, causing the additional injection button 110 to pop up and touch the smart component switch 120 to turn it on, thereby allowing the sensor device 125 to operate. When the additional injection button 110 is pressed, the switch 120 automatically disconnects, whereby the sensor device 125 records the movement of the relevant parts of the syringe during drug inhalation, thereby determining the drug dosage. Of course, it is conceivable that the laser sensor in the present invention can also be replaced by other suitable mechanical sensors, which are described in other embodiments of the present invention.

[0066] More specifically, in the present invention, the sensing device 125 may be a laser displacement sensor disposed at the front end of the rear sleeve 130. During the drug aspiration process, the laser displacement sensor is used to measure the circumferential displacement of the laser displacement sensor around the syringe axis and / or the axial displacement of the laser displacement sensor along the syringe axis during the rotation of the rear sleeve 130 relative to the front end portion 1 of the syringe, including the displacement length and displacement direction, so as to calculate the rotation amount of the rear end portion 2 of the syringe relative to the front end portion 1 of the syringe, and further determine the drug aspirated dose of the syringe.

[0067] In particular, the calculation of the inhaled drug dose can be achieved by an MCU communicating with the laser displacement sensor, which is configured to determine the metering zero point of the inhaled drug dose when the switch 120 is turned on, calculate the inhaled drug dose based on the metering zero point and the circumferential and / or axial displacement sensed by the laser displacement sensor, and record the injection time when the switch 120 is turned off.

[0068] In the preferred embodiment described above, the assisting device 100 may further include a display disposed within the sleeve 130 for displaying the inhaled dose calculated by the MCU. Of course, it is contemplated that the display may also display the current time, the last injection time, the next scheduled injection time, etc. Of course, the assisting device 100 of the present invention may communicate with the outside world via the MCU, thereby displaying various information on an external display.

[0069] According to another preferred embodiment of the present invention, the auxiliary device 200 includes a front sleeve 10 and a rear sleeve 20. The front sleeve 10 can be mounted on the front end portion 1 of the syringe and move therewith, and the rear sleeve 20 can be mounted on the rear end portion 2 of the syringe and move therewith. The rear sleeve 20 is similar to the rear sleeve 130 in the aforementioned embodiment. The auxiliary device 200 also includes an injection control assembly and the intelligent assembly disposed on the front sleeve 10 and the rear sleeve 20. The injection control assembly includes an additional injection button and a return spring, and the intelligent assembly includes a power supply, an MCU, and a sensor device. The sensor device is a mechanical sensor device. The sensor device includes a switch for measurement and a sensor element. The switch may include a first switch 11 and a second switch 21, and the sensor element may include a contact group 12, a first contact 22A, and a second contact 22B.

[0070] Figures 5A-5CThe auxiliary device 200 according to the present invention installed in place on the syringe is exemplarily shown. As shown in the figure, the front sleeve 10 is enclosed in the syringe front part 1 and can move with it, and the rear sleeve 20 is enclosed in the syringe rear part 2 and can move with it. The rear end structure of the rear sleeve 20 is similar to the rear end structure of the rear sleeve 130. Similarly, when the user uses the syringe to perform various operations, it is only necessary to operate the auxiliary device 200. For example, when the syringe is pressurized, the user only needs to rotate the rear end sleeve 20 relative to the front sleeve 10. An MCU and a power supply (for clarity, MCU and power supply are not shown in the accompanying drawings) for supplying power to the auxiliary device are provided in the front sleeve 10. In this preferred embodiment, a first switch 11 and a contact group 12 are also provided in the front sleeve 10. The contact group 12 is used to cooperate with the first contact 22A and the second contact 22B in the rear sleeve 20 to assist the MCU in calculating the drug dosage of the syringe, which will be described in detail below.

[0071] The contact sheet group 12 is composed of a plurality of first contact sheets 121 and a plurality of second contact sheets 122. Figure 6 As shown in the exploded view, each first contact 121 and each second contact 122 extend longitudinally on the inner circumference of the front sleeve 10. The first and second contact pieces 121, 122 are spaced apart and arranged around the longitudinal axis. Adjacent first and second contact pieces 121, 122 are insulated from each other. Each first contact piece 121 is connected to a power source, so that when the auxiliary device 200 is powered on, each first contact piece 121 has a high potential. Each second contact piece 122, insulated from the first contact piece 121, is connected to a different input point of the MCU. The first switch 11 can be turned on by the rear sleeve 20 moving forward and touching it, and automatically turns off when the rear sleeve 20 is no longer touching it. When the first switch 11 is turned on, the MCU enters the startup state.

[0072] Continue to refer to Figure 6 , a first contact 22A and a second contact 22B are provided in the rear end sleeve 20, and the first contact 22A and the second contact 22B are fixed on the inner circumference of the rear end sleeve 20 and can move with the rear end sleeve 20. The first contact 22A and the second contact 22B are positioned as follows, that is, in the process of the rear end sleeve 20 rotating relative to the front end sleeve 10 and moving forward or backward along the longitudinal axis, the first contact 22A and the second contact 22B can only contact two adjacent contact pieces at the same time. For example, when the first contact 22A contacts the first contact piece 121, since the first contact piece 121 and the second contact piece 122 are arranged at intervals, the second contact 22B only contacts a second contact piece 122 adjacent to the first contact piece 121, and vice versa. A second switch 21 connected between the first contact 22A and the second contact 22B is also provided in the rear end sleeve 20, as shown Figures 7A-7DAs shown in the simplified schematic diagram, when the second switch 21 is turned on, the first contact 22A and the second contact 22B are connected, thereby further connecting a first contact 121 in contact with the first contact 22A and the second contact 22B and an adjacent second contact 122. The rear sleeve 20 may further be provided with an additional injection button 40 and a return spring 41. The additional injection button 40 is disposed in an opening at the rear end of the rear sleeve 20 and acts synchronously with the injection button 4 of the rotary drug-inhaling syringe. In the initial state, the return spring 41 keeps the additional injection button 40 in a non-rebound state. When the syringe is pressurized, the injection button 4 of the syringe will rebound and overcome the elastic force of the return spring 41, causing the additional injection button 40 to rebound. When the additional injection button 40 rebounds, it will touch the second switch 21, turning it on. When the additional injection button 40 and the injection button 4 are pressed together, the second switch 21 is automatically disconnected. Of course, the additional injection button 40 and the return spring 41 are not necessary, and the second switch 21 can be turned on only by the pop-up of the injection button 4 of the syringe.

[0073] Now combine Figures 7A-7D The principle of calculating the amount of medication aspirated by the syringe using the auxiliary device 200 is explained below. As previously mentioned, when using a syringe to aspirate medication, the syringe's rear end portion 2 needs to rotate relative to the syringe's front end portion 1. The amount of medication aspirated by the syringe is related to the amount of rotation. The auxiliary device 200 of the present invention utilizes this characteristic to calculate the amount of medication aspirated. Figures 7A-7D The figure shows the positional relationship between the contacts and the contact group when the rear sleeve 20 rotates to different positions relative to the front sleeve 10 during the syringe drug aspiration process. According to the previous description, the auxiliary device 200 is in the activated state during the drug aspiration process, the first contact 121 has a high potential, and the second contact 122 is insulated from the first contact 121 and therefore does not have a high potential. Figure 7A In the figure, the first contact 22A contacts a first contact piece 121, and the second contact piece 22B contacts an adjacent second contact piece 122. Since the second switch 21 is turned on during the drug inhalation process, the first contact piece 121 and the second contact piece 122 form a loop through the first contact 22A and the second contact 22B, thereby making the second contact piece 122 that originally did not have a high potential have a high potential and feedback a high potential signal to an input point of the MCU to which it is connected (indicated by "+" in the figure), while the other second contacts do not have a high potential and therefore will not feedback a high potential signal to the corresponding input point of the MCU (indicated by "0" in the figure). Similarly, as the rear end sleeve 20 continues to rotate, the first contact 22A and the second contact 22B will slidably contact different contacts and correspondingly feedback high potential signals to different input points of the MCU (such as Figures 7B-7D(as shown), the MCU can calculate the rotation direction and amount of the rear sleeve 20 relative to the front sleeve 10 based on the power status of its various input points, and thus determine the syringe's inhaled drug dosage. It should be noted that the number of first and second contacts and corresponding MCU input points shown in the figure is merely exemplary and can be increased or decreased depending on the syringe type and precision requirements of the auxiliary device. For example, the number can be two, three, four, five, or more.

[0074] The working process of the auxiliary device 200 will now be described in conjunction with the use of the syringe. Figure 5A As shown, the syringe is not pressurized. At this time, the injection button 4 of the syringe and the additional injection button 40 of the auxiliary device 200 are not popped up, and the first switch 11 and the second switch 21 are both in the off state. When the syringe is pressurized, the rear sleeve 20 rotates relative to the front sleeve 10 and approaches it. As the pressurization progresses, the rear sleeve 20 touches the first switch 11 to turn it on, and the entire auxiliary device 200 enters the startup state. The multiple first contacts 121 in the front sleeve 10 are energized and have a high potential. When the pressurization is completed, as shown in FIG. Figure 5B As shown, the injection button 4 drives the additional injection button 40 to pop up, the second switch 21 is touched and turned on, and as mentioned above, one of the second contacts 122 will be energized. When the MCU first senses that a corresponding input point is energized, it confirms the metering zero point of the inhaled dose and stores the relevant data in the memory of the MCU. Of course, the metering zero point can also be set manually. When inhaling the drug, as Figure 5C As shown, the rear sleeve 20 is rotated in the opposite direction to move it away from the front sleeve 10. Since the first switch 11 is no longer touched, it will automatically disconnect. At this time, the MCU will logically determine that the auxiliary device 200 is still in operation and will not be powered off. As the rear sleeve 20 rotates, the MCU calculates the amount of medicine inhaled by the syringe in real time. During injection, as shown in FIG. Figure 5C As shown, the additional injection button 40 is pressed together with the injection button 4, and the second switch 21 is automatically disconnected because it is no longer touched. The MCU senses that the feedback signal of the corresponding input point disappears and records this time as the injection time. The MCU can be configured to enter the standby state after a delay period.

[0075] Furthermore, the front sleeve 10 may include a first section 100 and a second section 200 (eg Figure 8As shown), the inner diameter of the first section 100 is smaller than the inner diameter of the second section 200, thereby forming a step portion between the first section 100 and the second section 200, the first switch 11 is arranged at the step portion, and each first contact piece 121 and each second contact piece 122 are arranged on the inner circumferential surface of the second section. In conjunction with this, the outer diameter of the rear end sleeve 20 is smaller than the inner diameter of the second section 200, so that the rear end sleeve 20 can be inserted into the second section 200 of the front end sleeve 10 when moving toward the front end sleeve 10 and touch the first switch 11 arranged at the step portion. The auxiliary device 200 may also include a display for displaying the inhaled drug dose calculated by the MCU, which can be arranged in the front end sleeve 10 or the rear end sleeve 20. Of course, it is conceivable that the display can also display the current time, the last injection time, the next scheduled injection time, etc.

[0076] According to the preferred embodiment described above, when the rear end sleeve 20 touches the first switch 11 to turn it on, the rear end sleeve 20 of the syringe may still be some distance away from the pressurization completion position, and the distance may be, for example, 0.5 mm to 2 mm, preferably 1 mm, and the number of rotations required for the rear end sleeve 20 to move 1 mm along the longitudinal axis relative to the front end sleeve 10 may be half a turn.

[0077] According to the preferred embodiment described above, the auxiliary device can automatically calibrate the inhaled dose calculated by the MCU in response to a setback in the rotation of the rear end portion of the syringe relative to the front end portion of the syringe, so that the inhaled dose calculated by the MCU is consistent with the inhaled dose displayed in the syringe display window 5. The operator's setback in rotating the syringe at each dosage unit value will cause the speed of the rotating syringe to change, and this change can be measured by the sensor.

[0078] According to the preferred embodiment described above, the smart component may also include a user prompting device for prompting the user of the status of the syringe and the operations that the user needs to perform, etc. For example, the user can be prompted that the injection interval time is approaching and / or has been reached based on the last injection time data and the predetermined injection interval time data stored in the MCU, and the user can be prompted that the predetermined inhalation dose is approaching and / or has been reached during the syringe inhalation process based on the inhalation dose data stored in the MCU.

[0079] According to the preferred embodiment described above, the prompt mode of the user prompt device may include one or more of visual prompts, sound prompts and tactile prompts, that is, the user prompt device includes one or more of visual prompt devices, sound prompt devices and tactile prompt devices.

[0080] According to the preferred embodiment described above, the visual prompting device may include an indicator light for prompting the user through light in a changing state or a stable state, wherein the changing state of the light includes a change in brightness and / or color of the light.

[0081] According to the preferred embodiment described above, the sound prompting device may include a buzzer for prompting the user through sound.

[0082] According to the preferred embodiment described above, the tactile prompting device may include a vibrator for prompting the user through vibration.

[0083] According to the preferred embodiment described above, the intelligent component may further include a wireless module for wirelessly transmitting relevant data to a network and / or a corresponding data terminal device. The wireless module may include a Wi-Fi module and / or a Bluetooth module, and the data terminal device may include a computer and / or a smart mobile device such as a mobile phone or tablet computer. The relevant data may include one or more of injection time, injection interval, number of injections, and injection dose. Upon receiving the relevant data transmitted by the auxiliary device, the data terminal device may utilize the data to statistically analyze syringe usage and provide feedback to the user and / or individuals associated with the user, such as a physician or family member.

[0084] According to the preferred embodiment described above, the switch 120 , the first switch 11 and the second switch 21 may be micro switches, also known as sensitive switches, snap switches, etc.
