Abstract

Embodiments of the present invention monitor resistance to the movement of the ram and detect one or more injector operation conditions based on that resistance. Some embodiments automatically detect whether a syringe is present in each syringe chamber of an injector based on ram movement resistance so that subsequent steps in the inject process can be automatically initiated or delayed based on the presence or absence of the syringe(s). Other injector operation conditions that can be detected include the injector's syringe sleeve being misaligned for operation, the syringe's wiper being misaligned within the syringe barrel, an occlusion within the syringe, overpressure during injection, and so on. A common way to measure resistance of the ram's movement is how much current is required by the motor driving the ram.

通过电机电流测量的动力注射器的监测操作 Power injector by the motor current monitoring operation of the measurement

技术领域 FIELD

[0001] 本文通常涉及医疗液体注射系统的操作。 [0001] As used herein relates generally to medical fluid injection system in operation.

背景技术 Background technique

[0002] 在许多医疗环境中,医疗液体在诊断或者治疗过程中被注射进入患者体内。 [0002] In many medical environments, a medical fluid is injected in the course of diagnostic or therapeutic into a patient. 一个实例是造影剂注射进入患者体内,以改善利用动力液体注射系统的计算机断层扫描(CO、血管造影、磁共振(MR)或超声成像。 One example is the injection of contrast media into the patient, to improve the dynamic computed tomography using a liquid injection system (CO, angiography, magnetic resonance (MR) or ultrasound imaging.

[0003] 造影剂通常通过自动注射系统注射进入导管。 [0003] Contrast agents are generally injected by automated injection system into the catheter. 当能够改变用于注射造影剂的装置时,大多数系统包括与导管可操作地连接的灌注器。 When the apparatus can be changed for the injection of contrast agent, with most systems including infusion conduit operably linked. 注射器包括包裹灌注器的灌注器腔,其通常能够被重复使用若干次。 Perfusion chamber syringe package comprises a perfusion device, which can usually be reused several times. 注射器还包括在灌注器腔内可往复移动的挤压装置。 The syringe further comprising a pressing means reciprocatingly movable in the chamber infusor. 当挤压装置移动以在灌注器内制造部分真空时,造影剂被吸入灌注器内。 When the pressing means moves in the manufacture of a partial vacuum within the infusion device, the contrast agent is sucked into the pourer. 挤压装置的相反方向首先将气体排出灌注器,之后以由挤压装置运动的速度所确定的速率和量将造影剂运送至导管。 In the opposite direction of the first pressing means irrigator gas discharge, then at a rate and an amount of movement by the speed of the extrusion device the determined contrast agent transport to the catheter.

[0004] 此外,这样的流程能够包括除造影剂以外的液体的注射。 [0004] In addition, such processes can include injection of a liquid other than the contrast agent. 例如,可能需要生理盐水冲洗和/或输液治疗注射。 For example, a saline flush may be necessary and / or injection of infusion therapy. 因此,注射器能够包括用于包裹多个灌注器的多个灌注器腔,而注射器具有相对于每个灌注器腔的挤压装置。 Accordingly, the syringe can include a plurality of wrapping a plurality of perfusion lumen perfusion filter, with the syringe pressing apparatus each filling chamber relative. 这些额外的灌注器腔和挤压装置能够起到与以上讨论的相同的作用,唯一的差别是,不同于造影剂的液体被吸入并且运送出各自的灌注器。 These additional perfusion chamber and extrusion apparatus can play the same function as discussed above, the only difference is that the contrast agent is different from the liquid is sucked and transported out of the respective irrigator. 题为Medical Fluid Injection System的美国专利申请第12/094,009号(公开号2009/0149743)教示了利用注射器容纳多个灌注器,该申请被转让给本申请的受让人,并且通过引用全面地结合于此。 Entitled Medical Fluid Injection System of U.S. Patent Application No. 12 / 094,009 (Publication No. 2009/0149743) teaches a syringe device receiving a plurality of perfusion, which application is assigned to the assignee of the present application, and incorporated by reference fully incorporated herein.

[0005] 利用医疗液体填充灌注器和注射医疗液体的过程优选尽可能地自动化,以减少与注射器安装相关联的时间的量和/或最小化操作者失误的发生率。 [0005] The use of medical fluid filling the medical fluid infusion and injection process is preferably automated as much as possible to reduce the amount of time the syringe mounting associated with and / or minimizing the incidence of operator error. 在CT应用中,提高安装速度是特别重要的。 In CT applications to improve the speed of installation is particularly important. 通常产生操作者失误的一个步骤是将灌注器装载进适当的灌注器腔中。 A step of generating operator error generally is loaded into the infusion is appropriate in the perfusion chamber. 在某些情况下,操作者将灌注器装载进错误的灌注器腔中(例如,在不是所有的灌注器腔都被使用的流程中)。 In some cases, the operator is loaded into the wrong perfusion perfusion chamber (e.g., not all flow in the perfusion chamber are used in a). 在某些情况下,操作者试图将灌注器装载在适当的灌注器腔内,但意外地未对准灌注器,留下了不适合后续过程的灌注器。 In some cases, the operator attempts to prime the perfusion is loaded in an appropriate cavity, but accidentally misaligned perfusion, a subsequent process is not suitable for leaving the infusor. 在某些情况下,操作者太全神贯注于为患者准备治疗的其他任务,以致于他/她只是忘记装载灌注器。 In some cases, the operator is too preoccupied with other tasks to prepare for the patient's treatment, so that he / she just forgot to load irrigator. 在灌注器(多个灌注器)没有适当地装载进灌注器腔(多个灌注器腔)中的情况下而自动注射过程开始时,问题就产生了。 When the pourer (s pourer) is not properly loaded into the perfusion chamber (s perfusion chamber) in the case of the injection process is started automatically, a problem arises.

发明内容 SUMMARY

[0006] 本发明的实施方案监测对注射器的挤压装置的移动的阻力并且基于该阻力检测注射器的一个或多个操作条件。 [0006] Embodiments of the invention for monitoring the resistance to movement of the pressing device based on one of the syringe and the syringe detection resistance or more operating conditions. 一些实施方案基于挤压装置的移动阻力自动地检测灌注器是否存在于注射器的一个或多个灌注器腔中,使得在灌注器填充过程中的后续步骤能够基于灌注器(多个灌注器)的存在或者不存在自动地开始或者延迟。 Some embodiments automatically detects the pourer is present in one or more perfusion chamber syringe pressing apparatus based on the resistance to movement, such that subsequent steps in the filling process can be based on the perfusion reactor infusor (s infusor) of automatically starts the presence or absence or a delay. 能够被检测其他的注射器操作条件,包括注射器的灌注器套管对于操作未对准、灌注器接触刷(wiper)在灌注器筒内未对准、灌注器内的闭塞、注射过程中的过压等等。 Syringe can be detected other operating conditions, includes a syringe perfusion cannula for misalignment operation, perfusion contact brushes (Wiper) pourer cylinder misalignment, the occlusion of the infusion device, the overvoltage during injection and many more. 测量挤压装置移动的阻力的优选方式是根据电机驱动挤压装置所需要的电流是多少。 Preferred embodiment measuring the resistance to movement of the pressing means is a motor drive current pressing apparatus required is.

[0007] 在挤压装置移动的阻力被用于检测灌注器的存在的实施方案中,注射器的挤压装置能够进入到各自的注射器的灌注器腔中(例如,就像通常在灌注器填充过程那样),并且能够基于挤压装置的移动受到了多大的阻碍来确定灌注器的存在或者不存在。 Embodiment [0007] is used to detect the infusor pressing means resistance to movement exists in the syringe pressing apparatus can enter the respective syringe perfusion chamber (e.g., as the process typically filled in the pourer above), and how much can be hindered by moving the extrusion device is determined based on the presence or absence of perfusion. 如果这样的移动受到了极大量的阻碍(例如,大于阈限量),则能够推断出灌注器的接触刷正在阻碍移动,因此灌注器存在。 If such an extremely large amount of movement is hindered (e.g., greater than a threshold amount), it is possible to infer the brush is in contact infusor hinder the movement, so infusion exists. 如果这样的移动受到了比较小量的阻碍,则能够推断出没有灌注器的接触刷来阻碍移动,因此不存在灌注器。 If such a relatively small amount of movement is hindered, it is possible to infer that there is no contact with the perfusion is to hinder the movement of the brush, so there is no irrigator.

[0008] 本发明的实施方案能够提供若干优点中的一个或多个。 [0008] The embodiments of the present invention can provide one or more of several advantages. 例如,一些这样的系统与使用光或机械传感器来检测灌注器的存在的系统相比是有利的。 For example, some such system and the present system using an optical or mechanical sensor detects the infusor is advantageous compared. 在这样的系统中,医疗液体(尤其是造影剂)能够以干扰传感器的操作的方式附着在设备上,使它们表现得不可靠。 In such a system, the medical liquid (especially contrast) can interfere with the operation of the embodiment of the sensor attached to the device, so that they exhibit unreliable. 相反,本发明的实施方案能够基于非常容易测量且可重复的参数来检测灌注器的存在。 In contrast, embodiments of the present invention can be detected based on the presence of perfusion is very easy and repeatable measurement parameters. 本发明的多个实施方案所提供的重要优点是提高了效率并且节省了时间。 An important advantage of various embodiments of the present invention is to provide improved efficiency and time savings. 事先而不是事后检测多项此处所讨论的注射器操作条件能够避免浪费大量的时间。 In advance rather than after detection of a number discussed here syringe operating conditions can avoid wasting a lot of time. 然而,增加这样的流程的自动化能够使操作者以并行而不是以顺序地方式执行各个流程。 However, such an increase in process automation enables an operator to perform various processes in parallel rather than sequentially manner. 这样的时间节省在操作者在固定的时间段内必须保持完成流程的严格安排的设置(例如,CT)中是尤其重要的。 This saves the operator time to set a strict schedule to complete the process must be kept in a fixed period of time (eg, CT) is particularly important. 本发明的一些实施方案包括监测用于注射的操作条件,以避免对注射器自身的损害(例如,监测未对准的灌注器套管)。 Some embodiments of the present invention includes monitoring operating conditions for the injection, in order to avoid damage to the syringe itself (e.g., misalignment monitoring perfusion cannula). 一些实施方案包括监测注射器操作条件,以增强患者的安全性(例如,监测在注射过程中的过压条件)。 Some embodiments include monitoring the operating condition of the syringe, to enhance the safety of the patient (e.g., during injection monitoring overvoltage conditions). 通过本发明的实施方案能够提供这些和/或其他的优点。 By the embodiments of the present invention can provide these and / or other advantages.

[0022] 图2A-2B更具体地示出了灌注器/活塞组件40、45。 [0022] More specifically, FIGS. 2A-2B illustrates the pourer / piston assembly 40, 45. 在图2A中,灌注器70被灌注器/活塞组件45的灌注器腔75包裹。 In FIG. 2A, the infusion device 70 is perfused / piston assembly 45, the perfusion chamber 75 parcels. 在图2B中,没有灌注器存在于灌注器腔75中。 In FIG. 2B, no perfusion is present in the perfusion chamber 75. 如果给定的注射流程需要灌注器70存在于灌注器腔75中,则图2A中的构造是适当的。 If a given injection process requires the presence of the pourer 70 in the perfusion chamber 75, the configuration of FIG. 2A is appropriate. 相似地,如果流程不需要灌注器存在于灌注器腔75中,则图2B中的构造是适当的。 Similarly, if the process does not require perfusion is present in the perfusion chamber 75, the configurations are suitable 2B is FIG. 而另一方面,如果流程不需要灌注器存在于灌注器腔75中,则图2A中的构造是不适当的,而如果流程需要灌注器存在于灌注器腔75中,则图2B中的构造是不适当的。 On the other hand, if the process does not require perfusion is present in the perfusion chamber 75, the configuration of FIG. 2A is not appropriate, and if required the process is present in the perfusion perfusion chamber 75, the configuration in FIG. 2B It is inappropriate. 如下面更具体地讨论的,自动地确定灌注器是否如特定的流程所需要的被装载进灌注器腔是有利的。 As discussed in more detail below, automatically determining whether a particular process such as a perfusion needed is loaded into the perfusion chamber it is advantageous.

[0023] 结合图3A-3B讨论示例性灌注器/活塞组件105的功能。 [0023] discussed in conjunction with FIGS. 3A-3B functions of the exemplary pourer / piston assembly 105. 如所示,灌注器/活塞组件105包括灌注器腔110、挤压装置115、短桩(spud) 120以及电机125。 As shown, an infusion / piston assembly 105 includes a perfusion chamber 110, the pressing device 115, the short pile (spud) 120, and a motor 125. 灌注器腔110能够包括入口126和出口127。 Perfusion chamber 110 can include an inlet 126 and an outlet 127. 在图3A中,灌注器130被包裹在灌注器腔110中。 In FIG. 3A, the perfusion 130 is wrapped in the perfusion chamber 110. 灌注器130能够包括在注射操作过程中被灌注器/活塞组件105的短桩120接合的接触刷135,如下面更具体讨论的。 130 can include an infusion perfused shot operation / contactor assembly engaging a piston 105 of 120 short pile brush 135, as discussed in more detail below. 灌注器130能够包括与灌注器腔110的入口126相符合的进水口136,连同与灌注器110的出口127相符合的出水口137。 Perfusion 130 can include an inlet 110 of the perfusion chamber inlet 136 conforming 126, together with the outlet 110 of the pourer spout 137 127 consistent. 在图3B中,在灌注器腔110中不存在 In Figure 3B, absent perfusion chamber 110

[0024] 电机125能够包括在前进方向AD以及撤回方向RD两者上驱动挤压装置115的线性致动器。 [0024] RD linear motor 125 can include a driving device 115 of the actuator in both the extrusion direction of advance and withdrawal direction AD. 电机125能够构造为经过基本上整个的灌注器腔110 (从近端111到远端112)驱动挤压装置115。 After the motor 125 can be configured to substantially the entire perfusion chamber 110 (111 from the proximal end to the distal end 112) pressing the driving device 115. 挤压装置115的移动受到的阻碍的程度能够影响电机125必须运作来驱动挤压装置115的程度,反过来,电机125需要多大的电流来驱动挤压装置115。 The degree of movement is hindered pressing means 115 can affect the degree of operation of the motor 125 to be driven extrusion device 115, in turn, require much current motor 125 drives the pressing device 115. 在许多实施方案中,电机125所需要的电流直接正比于挤压装置115的移动的阻力。 In many embodiments, the motor 125 required current is directly proportional to the resistance to movement of the pressing device 115. 例如,阻式压力(resistance pressure)的确定可涉及斜率/截距形式的公式:y=mx+b。 For example, determining the pressure resistance (resistance pressure) in the formula may involve slope / intercept form: y = mx + b. 在该公式中,y将表示电机电流,X将表示阻式压力,以及m和b将是在生产/校正过程中从每个注射器得到的常数。 In this formula, y represents the motor current, X represents a pressure barrier, and m and b are constants in the production / correcting process obtained from each syringe. 因此,求解X将得到下面的公式:x=(yb)/m。 Thus, solving the following equation X obtained: x = (yb) / m.

[0025] 参考图3A,经确认,灌注器130存在于灌注器腔110内,电机125能够在前进方向AD上驱动挤压装置115直到短桩120接合灌注器130的接触刷135。 [0025] Referring to Figure 3A, confirmed, the infusion device 130 is present in the perfusion chamber 110, the motor 125 can drive the pressing means 115 in the forward direction until AD 120 engages the contact 130 pourer short pile brush 135. 由于挤压装置115遇到接触刷135,对挤压装置115的移动的阻力增加,从而电机125所需要的电流量增加。 Since the pressing device 115 encounters contact brushes 135, to increase resistance to movement of the pressing device 115, the motor 125 so as to increase the amount of current required. 由于挤压装置115将短桩120按压进接触刷135,因此接触刷135的外围在短桩120上折叠来形成凸缘140。 Since the pressing device 115 presses the short pile 120 into contact brushes 135, so that the contact brush 135 on the periphery of the short pile 120 is folded to form a flange 140. 在这种方式中,挤压装置115能够在前进方向AD上推动接触刷135,以及在撤回方向RD上拉动接触刷135。 In this manner, the pressing device 115 can be pushed in the forward direction AD of contact brushes 135, and pulled in withdrawal direction on the contact brushes 135 RD.

[0026] 当挤压装置115已经与接触刷135接合时,灌注器130能够被医疗液体填充,并且医疗液体能够经由导管注射进入患者的脉管系统。 [0026] When the pressing means 115 has been engaged with the contact brushes 135, 130 can be perfused filled with medical fluid, and the medical fluid can enter the patient's vasculature via the injection conduit. 为了使医疗液体填充灌注器130,电机125能够在前进方向AD上驱动挤压装置115直到接触刷135的前缘接近灌注器腔110的远端112。 In order to fill the medical liquid infusion device 130, the motor 125 can drive the brush pressing device 115 until contacting the distal end of the leading edge 135 is close to 112 of the perfusion chamber 110 in the forward direction AD. 在该步骤中,在接触刷135与灌注器130的内壁之间的摩擦力阻碍挤压装置115的移动。 In this step, the contact brush frictional force between the inner wall 135 and the obstruction 130. perfusion pressing means 115 moves. 在优选实施方案中,该摩擦力可以近似为55到65磅。 In a preferred embodiment, the frictional force may be approximately 55 to 65 lbs. 灌注器腔110的出口127能够被封闭,并且入口126能够与医疗液体源液体连通。 The perfusion chamber 110 outlet 127 can be closed, and the inlet 126 can communicate with a medical liquid source liquid. 之后电机125能够在撤回方向RD上撤回挤压装置115和接触刷135,从而在接触刷135与远端112之间的灌注器130内的产生负压,负压将医疗液体经由入口126与进水口136抽进灌注器130中。 After the motor 125 can be withdrawn in a withdrawal direction RD pressing means contact brushes 135 and 115, whereby negative pressure is generated in the contact brush perfusion between the distal end 135 and 112 130, the medical fluid via the suction inlet 126 and into the 136 outlet 130 is drawn into the infusion vessel. 由于挤压装置115和接触刷135被完全撤回,灌注器130被医疗液体填充。 Since the pressing means 115 and a contact brush 135 is completely withdrawn, the perfusion 130 is filled with medical fluid. 为了将医疗液体从灌注器130经由导管注射进入患者的脉管系统,入口126能够被封闭,并且出口127能够与导管液体连通。 For the medical fluid via a catheter into the patient's vasculature injected from the infusion device 130, the inlet 126 can be closed, and the outlet conduit 127 can be in communication with the liquid. 之后电机125能够再次在前进方向AD上驱动挤压装置115和接触刷135以将医疗液体从灌注器130中经由出水口137和出口127按出。 After the motor 125 can be driven in the forward direction of the pressing device 115 and AD again contacts the brush 135 to a medical fluid via the outlet 137 and the outlet from the press pourer 130,127.

The driver 220 short piling. 不同于在其中入口126与出口127分开的图3A-3B的灌注器腔110,图4的灌注器腔210包括单个的入/出口228,经由单个的入/出口228能够在每个方向上引导医疗液体。 Unlike in which the perfusion inlet 126 and outlet 127 are separated in FIG. 3A-3B infusor chamber 110, the chamber 210 in FIG. 4 comprises a single entry / exit port 228 can be guided in each direction through a single entrance / exit 228 medical liquid.

[0028] 图5为根据本发明的实施方案的说明性的注射系统400的框图。 [0028] FIG. 5 is a block diagram of an illustrative embodiment of the injection system of the present invention 400. 注射系统能够包括注射器405和注射器控制系统410。 The injection system 405 can include a syringe and injector control system 410. 注射器405能够包括一个或多个灌注器腔,连同一个或多个挤压装置以及一个或多个电机。 Syringe 405 can comprise one or more perfusion chamber, along with one or more devices and one or more motor extruder. 灌注器腔、挤压装置以及电机具有与本文中其他处讨论的那些相同的或相似的特性。 Perfusion chamber, compression means, and a motor having the same or similar to those properties discussed elsewhere herein.

[0029] 注射器控制系统410能够包括可编程处理器415和存储装置420,存储装置420能够存储各种为特定功能设计的软件模块。 [0029] The injector control system 410 can include a programmable processor 415 and a storage device 420, storage device 420 can store various kinds of software modules designed for specific functions. 如图5所示,存储装置420包括挤压装置动作数据模块425、阻力检测模块430、操作条件检测模块435以及注射过程模块440。 5, the pressing means comprises a memory means 420 the operation of the data module 425, a resistance detection module 430, the operating condition detecting module 435 module 440 and an injection process. 通过存储装置420存储的软件模块能够依据各种因素而变化,诸如注射器405的种类、注射过程的种类等等。 Stored software modules 420 can vary depending on various factors through the storage device, such as the kind, type and the like of the injector 405 during injection. 通过存储装置420能够存储许多的附加软件模块和/或各种软件模块的功能性能够被改良以适合于特定的应用。 By storing means 420 capable of storing a plurality of additional software modules and / or functionality of the various software modules can be modified to suit a particular application.

[0030] 当被可编程处理器415执行时,挤压装置动作数据模块425能够使可编程处理器415为每个挤压装置采集表明挤压装置在灌注器腔中在前进或者撤回方向上移动的挤压装置动作信息的集合。 [0030] When performed by a programmable processor 415, the operation of the compression means data module 425 enables the programmable processor 415 for each collection indicate that pressing means pressing means moves in the forward direction or withdraw in the perfusion chamber motion information collection apparatus extruded. 注射过程模块440能够指示可编程处理器415根据注射器操作过程(例如,灌注器填充过程、初步的生理盐水注射以检查外渗,等等)来移动挤压装置。 Injection process module 440 can indicate a programmable processor 415 in accordance with the operation procedure of the syringe (e.g., irrigators filling process, to check the initial extravasation saline injection, etc.) to move the pressing means. 挤压装置动作数据模块425能够辅助可编程处理器415来确定挤压装置确实在移动。 Pressing means capable of assisting the operation of a programmable data module 425 to processor 415 determines mobile pressing means does. 在一些实施方案中,挤压装置动作信息包括挤压装置相对于参考点的位置(例如,短桩的位置)的位置,诸如灌注器腔的近端或远端。 In some embodiments, the operation of pressing means pressing means includes a position information relative to a reference point (e.g., short pile position), such as a proximal or distal end of the perfusion chamber. 例如,为了检测灌注器是否存在,注射器控制系统410能够确定短桩是否已经前进了离其静止位置足够远以使得如果灌注器存在的话,短桩将遇到灌注器的接触刷。 For example, in order to detect the presence or absence irrigators, injector control system 410 can determine whether a short piling has been advanced sufficiently far away from its rest position such that it is present if the perfusion, perfusion is short pile will encounter a contact brush. 在另一个实例中,为了检测灌注器的接触刷是否未对准,注射器控制系统410能够在短桩位于灌注器腔的远端(在此处未对准的接触刷的前缘将首先遇到灌注器的远端)附近时来估计挤压装置的阻力水平。 In another example, in order to detect whether the brush contacts infusor misalignment injector control system 410 can be located at the distal end of the perfusion chamber is a short pile (herein misaligned contact brushes encounters the leading edge of the first the distal perfusion device) to estimate the level of resistance near the extrusion apparatus. 在一些实施方案中,挤压装置动作信息包括挤压装置已经移动的持续时间(例如,从诸如当挤压装置首先从静止开始移动、当挤压装置开始撤回等等的参考时间标记)。 In some embodiments, the operation of pressing means comprises duration information has moved pressing means (e.g., such as when the pressing means is first moved from rest, when the compression means begins to withdraw the reference time mark, etc.). 例如,如果已知挤压装置开始撤回X秒到灌注器填充过程中,则注射器控制系统410能够在X秒过去后开始监测挤压装置阻力,以确定是否在灌注器腔内制造了适当的真空。 For example, if it is known pressing apparatus starts X seconds to withdraw perfusion reactor filling process, the injector control system 410 can begin to monitor the pressing means resistance past X seconds, to determine whether an infusion chamber for producing a suitable vacuum . 在一些实施方案中,挤压装置动作信息包括挤压装置移动或加速的速率。 In some embodiments, the operation information includes a pressing means pressing speed or acceleration of the mobile device. 在一些实施方案中,挤压装置动作信息包括涉及可与一个或多个注射器操作条件相关的挤压装置的移动的其他信息。 In some embodiments, the device information including the operation information of other mobile device relates to extrudable associated with one or more syringes pressing operating conditions.

[0031] 当被可编程处理器415执行时,阻力检测模块430能够使可编程模块处理器415为每个挤压装置采集表明该挤压装置的运动在前进或者撤回方向上受到了多大的阻碍的阻力信息的集合。 [0031] When executed by a programmable processor 415, a resistance detection module 430 can cause a programmable processor module 415 for each collection indicate movement of the pressing device pressing device has been much obstacles in the forward direction or withdraw the information collection resistance. 对于在其中配置了一个或多个电机以驱动一个或多个挤压装置的系统,阻力信息的第一集合能够包括电机(多个电机)需要多大的电流来驱动挤压装置(多个挤压装置)。 For a configuration in which one or more motors to drive the system of one or more pressing devices, the resistance of the first set information can include a motor (a plurality of motors) need much current to drive the pressing means (pressing a plurality of means). 在一些实施方案中,阻力信息基于例如挤压装置的加速度的参数,而不是电机电流。 In some embodiments, the resistance of the acceleration information based on parameters such as extrusion apparatus, instead of the motor current.

[0032] 当被可编程处理器415执行时,操作条件检测模块435能够使可编程处理器415检测一个或多个注射器操作条件。 [0032] When performed by a programmable processor 415, the operating condition detecting module 435 enables the programmable processor 415 detecting one or more operating conditions of the injector. 操作条件检测模块435能够使可编程处理器415接收来自于挤压装置动作数据模块425的挤压装置动作信息的集合(多个集合)以及接收来自于阻力检测模块430的阻力信息的集合(多个集合)。 Operating condition detecting module 435 enables the programmable processor 415 receives the motion data from the pressing device module apparatus set pressing operation information 425 (multiple sets) and receiving a resistance from the resistance information detecting module 430 collection of (poly sets). 之后,如由操作条件检测模块435导致的,可编程处理器415能够基于挤压装置动作信息的集合(多个集合)以及阻力信息的集合(多个集合)来确定是否存在若干个注射器操作条件中的一个或多个。 Thereafter, as indicated by the operating condition detecting module 435 caused programmable processor 415 can be set based on the motion information extrusion apparatus (multiple sets) and a set of resistance information (multiple sets) to determine whether there is a plurality of operating conditions of the injector one or more.

[0033] 操作条件检测模块435能够使可编程处理器415监测多种注射器操作条件中的一个或多个。 [0033] The operating condition detecting module 435 enables the programmable processor 415 to monitor one or more operating conditions in a variety of injectors. 例如,一个这样的条件为对于操作未对准的灌注器套管。 For example, a condition for the operation of such misalignment perfusion cannula. 灌注器套管作为允许进入灌注器腔的门。 Perfusion cannula as it allows access to the perfusion chamber door. 如果灌注器套管没有适当地关闭(例如,由于灌注器的未对准),则短桩能够在挤压装置前进期间按压它或者在挤压装置撤回期间拉动它,并引起极大的损害。 If the infusion cannula is not closed properly (e.g., due to the misalignment of the infusion device), it is capable of pressing the short pile during the extrusion apparatus or pulls it forward during the extrusion apparatus withdrawn, and cause great damage. 操作条件检测模块435能够使可编程处理器415基于挤压装置动作信息(例如,为灌注器腔的近端或远端附近的短桩?)以及阻力信息(例如,电机电流峰值已经达到不正常的高水平?)来监测挤压装置不适当地接触灌注器套管。 Operating condition detecting module 435 enables the programmable processor 415 based on the operation information pressing means (e.g., a proximal perfusion lumen near the distal short pile or?) And resistance information (e.g., the motor has reached the peak current is not normal the high level of?) to monitor the pressing device inappropriately contacting perfusion cannula. 能够被可编程处理器415观测的条件的另一个实例,如由操作条件检测模块435促进的,为在灌注器中是否存在闭塞(例如,由于陈年的对比剂、灌注器制造异常等等)。 Another example can be a programmable processor 415 conditions observed, as facilitated by the operating condition detection module 435, whether there is a perfusion vessel occlusion (e.g., due to the aging of the contrast agent perfusion abnormalities manufacturing, etc.) . 例如,如果挤压装置动作信息和阻力信息表明,当挤压装置位于通常将导致最小阻力的位置时,对挤压装置的运动存在升高的阻力,则操作条件检测模块435能够使可编程处理器415提示灌注器可能具有闭塞。 For example, if the device information and the pressing operation information indicates that the resistance, when the compression means is in the normal position will result in a minimum resistance, the presence of elevated pressing means resistance to the movement, the operating condition detecting module 435 enables the programmable processing 415 tips perfusion may have closed. 可监测条件的另一个实例为灌注器接触刷在灌注器筒内是否未对准。 Another example may be to monitor conditions in the brush contact perfusion pourer barrel if misalignment. 如以上所暗示的,如果灌注器接触刷未与灌注器筒同轴对准,则灌注器接触刷的一部分能够首先接触灌注器筒的远端。 As implied above, if the brush is not in contact with the perfusion is coaxially aligned with the filling cartridge, the filling can be in contact first contacts the distal end portion of the perfusion cartridge brush. 这能够使灌注器接触刷被压碎,由于必须重新装载新的灌注器并且重新开始过程,这导致了极大的时间浪费。 This enables the pourer contact brushes are crushed, since it is necessary to reload new infusor and restarts the process, which results in a great waste of time. 例如,如果挤压装置动作信息和阻力信息表明,由于短桩接近灌注器腔的远端而对挤压装置运动存在升高的阻力,则操作条件检测模块435能够使可编程处理器415提示灌注器接触刷是未对准的。 For example, if the device information and the pressing operation information indicates that the resistance due to the short pile proximity of the distal end of the perfusion chamber and the presence of elevated resistance to movement of the extrusion apparatus, the operation condition detection module 435 enables the programmable processor 415 prompts perfusion contact brush is misaligned.

[0034] 在优选实施方案中,操作条件检测模块435能够使可编程处理器415通过基于挤压装置在前进上受到的阻式压力得出结论而确定在灌注器腔(多个灌注器腔)中是否存在灌注器。 [0034] In a preferred embodiment, the operating condition detecting module 435 enables the programmable processor 415 determines concluded (more perfusion chamber) in the perfusion chamber by a barrier means by pressure based on the pressing forward whether there irrigator. 如果阻力信息的第一集合表明第一挤压装置的移动在前进方向上被预定量的压力或更大的压力所阻碍,则操作条件检测模块435能够使可编程处理器415得出在第一灌注器腔中存在灌注器的结论。 If the resistance of the first set of information indicates that the mobile device is first pressed in the advance direction of the pressure is a predetermined amount or more hindered, then operation condition detection module 435 can be made in the first programmable processor 415 stars perfusion chamber's conclusion there is irrigator. 在这种情况下,可以推断出由灌注器的接触刷施加了阻式压力,意味着灌注器实际存在。 In this case, the contact can be deduced from the infusor brush pressure applied to the resistive means irrigators actually exists. 如果阻力信息的第一集合表明第一挤压装置的移动在前进方向上被小于预定量的压力所阻碍,则操作条件检测模块435能够使可编程处理器415得出在第一灌注器腔中不存在灌注器的结论。 If the resistance of the first set of information indicates that the movement of the first pressing means is smaller than a predetermined amount is hampered by the pressure in the forward direction, the operating condition detecting module 435 enables the programmable processor 415 in the stars of the first filling chamber irrigators conclusion does not exist. 在这种情况下,可以推断出挤压装置在前进上未受灌注器接触刷的阻碍,意味着没有灌注器存在。 In this case, the extrusion apparatus can be inferred in the advance impede reperfusion contact brush unaffected, meaning that no perfusion is present.

·[0035] 表明灌注器存在的挤压装置阻式压力的量可以从一个实施方案到另一个实施方案发生变化。 * [0035] showed the presence of an amount of an extrusion apparatus perfusion pressure resistance may change from one embodiment to another embodiment. 在许多实施方案中,需要大约55-65磅/平方英寸(psi)来从灌注器接触刷的静止位置移动它。 In many embodiments, it requires approximately 55-65 pounds / square inch (psi) to move it from the rest position contact brushes irrigator. 因此,在这样的实施方案中,将预定的压力量设置为小于55磅/平方英寸(例如,10磅/平方英寸)能够提供所需要的效果。 Thus, in such an embodiment, the predetermined amount of pressure is set to less than 55 pounds / square inch (e.g., 10 lbs / square inch) to provide the desired effect.

[0036] 当被可编程处理器415执行时,注射过程模块440能够使可编程处理器415执行各种与将医疗液体注射进入患者的脉管系统相关的功能。 [0036] When performed by a programmable processor 415, the injection process enables the module 440 to perform various programmable processor 415 associated with the medical fluid injected into the patient's vasculature function. 如所讨论的,优选注射过程尽可能地自动化。 As discussed, preferably the injection process automation as possible. 自动检测在灌注器腔(多个灌注器腔)中灌注器存在或者不存在能够加强注射过程。 Automatically detecting the presence of perfusion in the perfusion chamber (s perfusion chamber) or can enhance the injection process does not exist. 具体而言,在一些实施方案中,如果确定了在各自的灌注器腔中存在灌注器,则注射过程模块440能够使可编程处理器415自动开始灌注器填充过程。 Specifically, in some embodiments, if it is determined in the presence of a respective perfusion chamber is perfused, the injection process module 440 can automatically cause a programmable processor 415 begins filling process is perfusion. 在一些实施方案中,如果确定了(a)在各自的灌注器腔中不存在灌注器,(b)灌注器套管未对准,(c)灌注器接触刷与灌注器筒不是同轴的,(d)在灌注器中存在闭塞,等等,则注射过程模块440能够使可编程处理器415停止注射过程并且警告操作者。 In some embodiments, if it is determined (a) is not present in the perfusion chamber in the respective infusion, (b) misalignment perfusion cannula, (c) filling the brush contact perfusion cartridge is not coaxial , (d) present in the infusion vessel occlusion, and the like, the injection process module 440 enables the programmable processor 415 stops the injection process and alert the operator.

[0037] 在一些实施方案中,当注射器将造影剂注射进入患者的脉动系统时,操作条件检测模块435能够使可编程处理器415监测注射器操作条件。 [0037] In some embodiments, when the syringe is injected into the patient a contrast agent pulsation system, the operating condition detecting module 435 enables the programmable processor 415 to monitor the operating conditions of the injector. 例如,一个这样的条件为注射过压。 For example, one such injection overpressure condition. 如果挤压装置动作信息和/或阻力信息表明在注射过程中的异常高的阻力,则注射过程模块440能够使可编程处理器415停止过程并警告操作者。 If the pressing device operation information and / or information indicates abnormally high drag resistance during injection, the injection process module 440 enables the programmable processor 415 stops the process and alert the operator. 操作条件检测模块435的这个功能和相似的功能能够提供患者显著提高的安全性。 This feature similar functions and operating condition detecting module 435 is capable of providing significantly improved safety of the patient.

[0038] 注射器控制系统410能够放置于各种位置。 [0038] The injector control system 410 can be placed in various positions. 在优选实施方案中,注射器控制系统410能够放置于注射器405自身中。 In a preferred embodiment, the injector control system 410 can be placed in a syringe 405 itself. 在一些实施方案中,注射器控制系统410能够与注射器405分开放置。 In some embodiments, the injector control system 410 and the injector 405 can be placed separately. 在一些实施方案中,注射器系统410能够放置在远离注射器405并且能够经由网络445 (例如,因特网)与注射器405沟通的服务器上。 In some embodiments, the injector system 410 can be placed away from the syringe 405 and 445 via a network (e.g., the Internet) to communicate with the server 405 of the syringe. 在这样的实施方案中,操作者能够将命令输入进控制板,注射器中的部件能够打包命名并在网络445上将其发送至注射器控制系统410,并且注射器控制系统410能够初始化响应动作并经由网络445与注射器405沟通该动作。 In such an embodiment, the operator can input commands into the control panel, the syringe can be packaged in a member name and transmits it to the injector control system 410 over the network 445, and injector control system 410 can initiate responsive actions via network 445,405 communicate the action with a syringe.

[0039] 图6示出了能够根据本发明的实施方案实施的说明性的方法。 [0039] FIG. 6 shows an illustrative embodiment of the method can in accordance with embodiments of the present invention. 如所示,该方法包括向注射器提供如在本文中其他处讨论的那些特性(505)。 As shown, the method comprising providing those features (505) as discussed elsewhere herein into the syringe. 图6的方法包括至少两个灌注器腔、电机以及挤压装置,但应当理解,本文中显示且讨论的原理能够并入使用单个灌注器的注射器的方法。 The method of FIG. 6 comprises at least two perfusion chamber, a motor and a pressing means, it should be understood that the principles of the display and discussed herein can be incorporated into a single use syringe of the infusor.

[0040] 图6的方法包括移动第一挤压装置(510)以及移动第二挤压装置(515)。 Method [0040] FIG. 6 comprises moving a first pressing means (510) and moving the second pressing means (515). 例如,该方法能够包括使第一挤压装置在注射器的第一灌注器腔中在前进方向上移动第一距离。 For example, the method includes first extruding means capable of moving a first distance in the traveling direction of the first filling chamber syringe. 相似地,该方法能够包括使第二挤压装置在注射器的第二灌注器腔中在前进方向上移动第二距离。 Similarly, the method can include moving the second pressing means in the forward direction a second distance in a second perfusion chamber syringe. 在优选实施方案中,使挤压装置(多个挤压装置)在前进方向上移动能够包括利用电机(多个电机)而驱动挤压装置(多个挤压装置)。 In a preferred embodiment, the pressing means (a plurality of pressing means) in the forward direction to drive the pressing means can comprise (a plurality of pressing means) by a motor (s motors).

[0041] 由于挤压装置被移动(510、515),该移动的阻力能够被测量。 [0041] Since the pressing device is moved (510, 515), the movement resistance can be measured. 该方法能够包括测量第一挤压装置在前进方向上受到多大的阻碍(520)。 The method can include measuring a first pressing means being much hindered (520) in the forward direction. 相似地,该方法能够包括测量第二挤压装置在前进方向上受到多大的阻碍(525)。 Similarly, the method can include measuring a second pressing means being much hindered (525) in the forward direction. 如在本文中其他处讨论的,在使挤压装置(多个挤压装置)在前进方向上移动涉及利用电机(多个电机)而驱动挤压装置(多个挤压装置)的实施方案中,测量该移动受到多大的阻碍能够包括测量电机(多个电机)需要多大的电流来驱动挤压装置(多个挤压装置)。 As discussed elsewhere herein, when the pressing means (a plurality of pressing means) directed in the forward direction to drive the pressing means (a plurality of pressing means) by the motor (s motors) embodiments measuring the movement is hindered can include a measure of how much the motor (s motors) need much current to drive the pressing means (a plurality of pressing means).

[0042] 在图6的方法中,可以确定出第一挤压装置是否已经移动了第一距离(530)以及第二挤压装置是否已经移动了第二距离(535)。 [0042] In the method of Figure 6 may be determined whether a first pressing means has moved a first distance (530) and whether a second pressing means has moved a second distance (535). 在许多实施方案中,在可以得出有关在各自的灌注器腔中存在或不存在灌注器的任何结论之前,挤压装置必须移动至少阈值距离。 In many embodiments, the before any conclusions can be drawn about the absence or presence of irrigators in the respective perfusion chamber, the pressing means must be moved at least a threshold distance. 例如,如果挤压装置的移动小于阈值距离,则其可能还没有移动到灌注器接触刷会在的地方。 For example, if a mobile pressing device less than a threshold distance, it may not have moved to contact the brush will perfusion place. 在该实例中,将得出不存在灌注器的错误结论。 In this instance, the wrong conclusion in the absence of perfusion device. 出于该原因或者相似的原因,许多实施方案包括确定是否每个挤压装置都已经移动了阈值距离。 For this reason or similar reasons, many embodiments include determining whether each of the pressing means have been moved a threshold distance. 如果第一挤压装置已经移动了第一距离,则第一挤压装置能够再次被移动(510),而如果第二挤压装置还没有移动第一距离,则第二装置能够再次被移动(515)。 If the first pressing means has moved a first distance, the first pressing means can be moved (510) again if the second pressing means has not moved a first distance, the second device can be moved again ( 515).

[0043] 如果挤压装置已经移动了阈值距离(例如,如果灌注器存在的话,足够远以遇到灌注器),则可以确定关于在各自的灌注器腔中存在/不存在灌注器。 [0043] If the pressing means has moved a threshold distance (e.g., if perfusion is present, far enough to encounter irrigator), it may be determined on the presence / absence of perfusion in perfusion chamber of each. 可以确定出是否第一挤压装置的移动的阻力超过了第一预定量(540)以及是否第二挤压装置的移动的阻力超过了第二预定量(545)。 It may determine whether the first resistance to movement of the pressing means exceeds a first predetermined amount (540) and whether a second resistance to movement of the pressing means exceeds a second predetermined amount (545). 如果第一挤压装置在前进方向上的移动被小于第一预定量的压力所阻碍,则可以得出在第一灌注器腔中不存在灌注器的结论(550)。 If the movement of the first pressing means in the forward direction is smaller than a first predetermined amount of pressure obstructed, it may be concluded (550) is not present in the perfusion chamber in the first filling. 另一方面,如果第一挤压装置在前进方向上的移动被第一预定量的压力或更大的压力所阻碍,则可以得到在第一灌注器腔中存在灌注器的结论(555)。 On the other hand, if the movement of the first pressing means in the forward direction is impeded by a first predetermined amount of pressure or more, the conclusion can be obtained in the presence of a first pourer in the perfusion chamber (555). 相似地,如果第二挤压装置在前进方向上的移动被第二预定量的压力或更大的压力所阻碍,则可以得出在第二灌注器腔中存在灌注器的结论(560)。 Similarly, if the movement of the second pressing means in the forward direction is hindered by the second predetermined amount of pressure or more, it can be concluded that the presence of perfusion in the second device in the perfusion chamber (560). 另一方面,如果第二挤压装置在前进方向上的移动被小于第二预定量的压力所阻碍,则可以得出在第二灌注器腔中不存在灌注器的结论(565)。 On the other hand, if the movement of the second pressing means in the forward direction is less than the second predetermined amount of pressure obstructed, it may be concluded in the absence of a second pourer in the perfusion chamber (565). 在一些实施方案中,第一预定量的压力和第二预定量的压力均大约为10磅/平方英寸。 In some embodiments, the second predetermined amount of pressure and the predetermined pressure of the first average amount of about 10 lbs / square inch.

[0044] 在优选实施方案中,基于在灌注器腔中是否存在灌注器的确定能够自动地采取后续动作。 [0044] In a preferred embodiment, based on the determination whether there is a perfusion in perfusion chamber is capable of automatically taking subsequent action. 如所示,如果得出在第一灌注器腔中不存在灌注器的结论(550),则操作者能够被警告(570),并且如果得出在第二灌注器腔中不存在灌注器的结论(565),则操作者能够被警告(585)。 As shown, if concluded (550) is not present in the perfusion chamber in the first filling, the operator can be warned (570), and if the results do not exist in the second infusion in the perfusion chamber Conclusion (565), the operator can be warned (585). 如果确定了在第一灌注器中存在灌注器(555),则灌注器填充过程能够自动地对该灌注器开始(575),并且如果确定了在第二灌注器腔中存在灌注器(560),则灌注器填充过程能够自动地对该灌注器开始(580 )。 If it is determined that there pourer (555) in a first perfusion reactor, the process can begin filling perfusion device (575) of the infusion device automatically, if it is determined in the presence of the second filling chamber pourer (560) , it is filled the filling process automatically starts the pourer (580). 基于在灌注器腔中是否存在灌注器,依据注射器的类型、注射流程以及各种其他的因素,可采取后续动作。 Based on whether there is perfused at the perfusion chamber, depending on the type of syringe, the injection process and various other factors, may take a subsequent action.
