Description

The invention relates generally to a fluid control system and a method for administering a fluid to a patient from multi-purpose metered containers. According to the invention, a fluid control system (CTC) is adapted to automatically deliver a fluid for injection to a patient.

State of the art

In many medical situations, a patient is given a medical fluid during diagnosis or treatment. One example is the administration of a contrast agent to a patient for image enhancement during a diagnostic imaging procedure, such as computed tomography (CT), angiography, magnetic resonance imaging (MR) or ultrasound imaging using an automatic fluid injection system.

Various manual and automated administration systems are known to be used to carry out the above procedures. In the system described in the publication of international application WO 2004/091688 A2, or in the publication of international application WO 2007/033103 A1, containers from which fluid is taken during administration must be prepared for manual use, i.e. they must be manually punctured and manually set to the extraction position after piercing.

The usual procedure for the preparation, manual manipulation and regulation of the contrast medium from a multi-dose container is described as follows.

Prior to use, multi-dose containers with a contrast agent are preheated with a heater, usually located near the diagnostic imaging device. The temperature of the heater is set to normal body temperature, i.e. about 37 ° C. Then the specialist removes the container with the contrast agent from the heater. To open the rubber seal, a plastic protective cap is removed from the end of the multi-dose containers. A needle with an internal channel is connected to a syringe with a contrast medium, then a technician manually inserts it into the rubber seal on a multi-dose container to supply the syringe line. For contamination reasons, the needle must be replaced approximately every 6-8 hours. Next, a multi-dose container is placed in a container holder suspended in an IV stand, in a vertical orientation and with the downstream end of the container neck. Then, the above steps are repeated for one container filled with saline. Next, the technician collects the required contrast agent and saline from multi-dose containers in the syringe container using the user syringe interface. Remove the protective packaging for the connecting tube with the cannula for the new patient. Manually remove the cap used to clog the connector on the supply line of the patient syringe. A cannula connection connects the patient connecting tube and the patient supply line. Then the technician displaces the air from the tubes, manually activating the syringe, which then pumps saline and contrast medium into the drive. The technician then checks the tubes visually to make sure that the lines are clean and accordingly stops the syringe. Next, the packaging is removed from the new cannula connector and the connector is fixed to the end of the patient tube.

The manual procedure described above is expensive and not very effective, therefore, the objective of the present invention is to achieve a higher level of automation. The multi-purpose apparatus for administering drugs disclosed in the publication of international application WO 2008/076631 A2 shows a somewhat higher level of automation.

However, simple automation creates additional problems. With a multi-dose container, the problem is always that the container is used longer than the recommended time of use or the containers are reused from which the needle was previously removed.

Thus, it is desirable to have a fluid control system that is safe and effective in use. In particular, it would be desirable to have a system that accurately and accurately controls fluid containers and fluid recovery. It is also essential that for all the time the container is used, the fluid supply remains free from contamination.

It would also be desirable to have a fluid control system that is suitable for the use of a number of fluids, such as contrast media, saline, flushing fluids, and involving the use of containers of various sizes.

A brief description of the invention.

Based on the foregoing, the object of the present invention is to provide a fluid control system (CTC) that solves problems and eliminates the disadvantages associated with the practice of using conventional fluid injection.

A fluid control system (CTS) according to the invention is adapted to automatically supply a fluid when it is introduced to a patient. According to the invention, the CTCS comprises a fluid control device (CTC), a fluid transfer system (CTS), and a syringe.

The TCF serves to store and control fluid from multi-dose containers, although storage and control of fluid from single-dose containers is also possible. It is understood that the term "container" also includes at least a bottle, bag, casing, cartridge, or karbul. The SPTS connects the outlet of the containers stored inside the UUTS with a syringe, and the syringe draws fluid using the SPTS from the containers and injects it into the patient control device. The syringe contains at least one supercharger, and it is programmed to inject a given amount of fluid at a given flow rate.

The UUTC includes at least one rotating carousel, with a vertical axis of rotation, at least two container holders mounted on the rotating carousel, said container holders being adapted to position the container vertically with the open end of the neck facing down, and a needle holder mounted below the rotating carousel and oriented so that the needle holder will align the needle connected to the needle holder along the axis of the container immersed in the container holder, and at the same time in the puncture position.

In one embodiment of the invention, the TCB contains two rotating carousels. In another embodiment, the TCB further comprises one or more, preferably two, container holders not secured to the rotating carousel.

It would be preferable that each rotating carousel would be mounted in a separate chamber, and each container holder not mounted on the rotating carousel would also be mounted in a separate chamber. In one embodiment, the TCB has a housing frame on which one or more cameras are mounted.

The rotating carousel preferably has a carousel drive shaft located on the pivot axis.

On the drive shaft, a plate can be fixed on which container holders are vertically mounted.

In one embodiment, up to ten container holders may be attached to the rotating carousel, preferably five container holders are attached to the rotating carousel. All container holders attached to the same rotating carousel can be adapted to hold containers of equal size. Alternatively, some container holders may be adapted to hold containers of a different size from the containers of other container holders. One container holder is preferably adapted to hold a container that is made smaller in relation to other containers.

The container holders are preferably equally spaced from each other in a circle about the axis of rotation.

At least one chamber, preferably from chambers on a rotating carousel, may be temperature controlled.

Each chamber may preferably be accessible through a hinge cover or door. Such a lid or door may be transparent or have a window for visually inspecting the contents of the camera.

The TCB may further comprise, for each rotating carousel, a carousel drive device having a motor and means for transmitting rotation from the axis of the motor to the shaft of the rotating carousel. Preferably, the UUTS further comprises means for disengaging the shaft of the rotating carousel from the axis of the motor in case the lid or chamber door located in said rotating carousel is open.

Each needle holder can be movably mounted on a linear slide that allows the needle holder to slide in the vertical direction. The TCB may further comprise, for each needle holder, an automatic puncturing device having a motor and means for moving the needle holder along linear slides.

The TCB may further comprise a central electronic control system (SCEU) for controlling the carousel drive device and the automatic puncturing device. Additionally, the SCEU can be in communication communication and for monitoring / control with:

a - an information output device, such as, for example, a display;

b - a user input device similar to a touch panel or keyboard;

c - temperature in temperature controlled chambers;

d - fluid level sensors;

e - needle position control sensors;

f- rotary carousel position control sensors;

g — valves in the SPTS pipeline;

h - a two-way data transmission system for communication with an HF syringe and / or computer network;

i - a one-way data transmission system, for example, a reader for reading data from data on storage on containers or fluid transfer systems (SPTS);

j is the storage device.

The fluid transfer system comprises: a first transfer pipe with at least two first ends, each of the first ends being connected to a needle, and at least two second ends, with each second end corresponding to the first end; a manifold having at least two inlets and one outlet, wherein the second ends of the transfer pipe are connected to the inlets of the manifold; wherein the second pipeline is connected to the outlet of the collector with its first end; and a valve mounted between each first end and the second end of the first transfer pipe. By means of valves, fluid can be selectively removed from one of the punctured containers.

The second end of the second transfer pipe may be adapted to be connected to a syringe.

The fluid transfer system may further comprise means for storing data for storage — a unique identifier for the fluid transfer system. When reading, the unique identifier of the SCEU can record the operation of a particular fluid transfer system and alert the user through the information output device when the maximum needle usage time is reached.

The base of the needle includes a seat and a means of attachment for connecting the needle to the appropriate place of landing and a means of attachment with the needle holder UUTS. The upper part of the needle is adapted to enter the container wall. To ensure easy extraction of fluid through the needle, an internal channel needle is preferred. To prevent contamination, the needle may be closed before using the cuff.

The present invention is directed to a method for automatically supplying a fluid upon administration to a patient, comprising the steps of:

- providing a fluid control device adapted to place at least one fluid container in a vertical position with a downwardly facing open end of the neck and having a needle holder mounted and oriented such that the needle holder will position the needle connected to the needle holder, coaxially in line with the axis of the container loaded in the container holder, while being in the piercing position;

- providing a fluid transfer system having a transfer pipe with a first end connected to a needle and a second end adapted to be connected to a syringe;

- loading at least one container with the downward open end of the neck facing down into the fluid control device, wherein said open end of the neck is closed by a partition;

- attaching the needle to the needle holder and the second end of the transfer pipe to the syringe;

- piercing the septum with a needle;

- fluid intake from the container.

The method further comprises the step of removing the needle from the container wall. Removing the needle from the septum is carried out in response to a signal that has triggered due to the fact that either the punctured container is empty, the maximum time for using the container has been reached, or the maximum time for using the needle has been reached. These usage maximums are recorded by a timer connected to a central electronic control system (SCEU) of a fluid control device. The fluid level / volume of the punctured container can be monitored by the SCEU using appropriate level / volume sensors.

In another embodiment, at least two containers are loaded into a fluid control device. The fluid control device further has means for locating each of the containers respectively in axial alignment with the needle holder. The method further comprises the step of moving the second container to a position in which it is in axial alignment with the needle holder, pushing the needle into the septum and withdrawing fluid from the second container.

DETAILED DESCRIPTION OF THE INVENTION

First Exemplary Embodiment of a Fluid Management System

SUTS (fluid control system), according to the first embodiment of the invention described here, is adapted for automatically supplying pre-heated contrast medium (KB) and unheated physiological saline to a KV syringe, for administration to a patient from a container filled with KB (KB container) or from a container filled with saline (saline container).

According to this embodiment of the invention, the fluid management device (TCB) 100 shown in FIGS. 1-4 consists of four separate chambers 20a, 20b, 21a, 21b. The chambers 20a and 20b are temperature-controlled and are designed to accommodate HF containers 22. The chambers 20a and 20b are arranged vertically, one above the other, and mounted on the frame 14 of the housing. The chambers 21a and 21b are made with uncontrolled temperature and are designed to accommodate salt containers. The containers 21a and 21b are also mounted vertically, one above the other, and mounted on the frame 14 of the housing, next to two temperature-controlled chambers 20a, 20b. The UUTS 100 is enclosed in plastic molded parts to protect internal components from the environment. Access to each chamber 20a, 20b, 21a, 21b is provided by individual hinged doors 24a, 24b, 25a, 25b with a transparent inspection window for visual observation of the contents of each chamber.

The central electronic control system (SCEC) (not shown) is located in the middle section between two vertically mounted temperature-controlled chambers 20a, 20b and is mounted on the frame 14 of the housing.

The rotating carousel shown in detail in FIGS. 13 and 14 is fixed inside each temperature-controlled chamber 20a, 20b, namely, on the vertically located carousel drive shaft 27. The drive shaft 27 of the carousel is mounted on the axis of the bearing, and said bearing is securely mounted on the frame 14 of the housing. The carousel drive unit is mounted and positioned so as to be able to rotate the rotating carousel by means of a central electronic control system (SCEU). The carousel drive unit consists of a motor, a reduction gearbox and an auxiliary chassis (cylindrical rectangular gears, belts, etc.), of which the main gear 2, the motor gear 3 and the intermediate gear 4 can best be seen in Figs. 4, 11 and 12.

Inside each temperature-controlled chamber 20a, 20b, container holders are made for each of the five HF containers 22 (shown in detail in Figs. 13 and 14), for their location, orientation and mounting, in which they can be aligned axially with the holder 10 needles of an automatic piercing device. Each holder of the KB container is mounted evenly spaced from the holder of the KB container around the circumference around the drive shaft 27 of the carousel, and is vertically mounted on the plate 7, and the said plate 7 is mounted on the drive shaft 27 of the carousel. Each container holder contains two clamps 28 and a wire container grid 8.

Inside each temperature-controlled chamber 21a, 21b, a container holder is provided for arranging, orienting and securing the salt container 23, while it can be aligned axially with the needle holder 10 of the automatic piercing device (see, for example, FIG. 4) . The container holder is mounted vertically on the plate 18, and the said plate 18 is mounted on the frame 14 of the housing. Each container holder contains two clamps 28 and a wire container grid 8.

The automatic puncturing system, as shown in more detail in FIGS. 9 and 10, comprises a needle holder 10, a linear slide 9 for a needle holder 10, and a needle drive device 12, including a motor, a reduction gear, a lead screw. The linear slide 9 with the needle holder 10 is mounted vertically on the frame 14 of the housing, below each of the four chambers 20a, 20b and 21a, 21b. Said automatic piercing device is arranged and oriented so that the needle holder 10 is adapted to axially align the needle 11 with the axis of the container 22, 23, which must be punctured.

To ensure the possibility of fixing the UUTS 100 on the upper carrying handle 1, a crossbar 31 is mounted on the frame 14 of the housing.

As shown in FIGS. 1 and 4, the fluid transfer system (SPTS) includes a needle 11 for each chamber adapted to be inserted into the needle holder 10 under the chamber. The needle 11 shown in FIGS. 5 and 6 has a base 41 and an upper portion 42. The needle 11 is ventilated. The base 41 has two guide grooves 45 on opposite sides that are configured to support the respective slide guides 55 for the needle holder 10 (see Figs. 7 and 8). The hole 44 in the base is adapted for the mounting rod 54 of the needle holder 10 when the needle 11 is inserted into the needle holder 10. The needle 11 preferably has a cuff 43 to prevent infection before use. SPTS additionally contains a pipe 15, 16 connected to each needle 11 and adapted for supplying fluid from a punctured container to an HF syringe (see Figs. 1 and 4). Between the pipe 15 of the needle 11 of the upper temperature-controlled chamber 20a and the pipe 16 of the needle 11 of the lower temperature-controlled chamber 20b, a Y-shaped connecting element 17 is installed. A Y-shaped connecting element 17 is installed between the pipe 15 of the needle 11 of the upper temperature-controlled chamber 21a and the needle pipe 16 of the lower temperature-controlled chamber 21b. The pipe 18 connects the outlet end of the Y-shaped connecting element 17 with the connecting plug of the KV syringe. Valves (not shown) are mounted between each needle 11 and the Y-shaped connector to control fluid from a respective punctured container to a Y-shaped connector. By means of valves, the fluid can be selectively removed by a KV syringe from a punctured upper or lower container filled with KB or saline.

SUTS - Functional Description

Central electronic control system

The following describes the central electronic control system (SCEU), which is used to communicate with sensors and control units of the TCB. SCEU can also be connected to a user interface device designed to provide him with information or to receive it from him. In particular, SCEU is adapted for communication and, accordingly, launching a rotating carousel and an automatic device for piercing all cameras. SCEU can also allow data storage, one-way transfer of information between the data storage medium on containers authorized for use and authorized for use by SPTS, and two-way transfer of information with an approved HF syringe.

Preheating and temperature control

Pre-heating of KB containers to approximately 37 ° C inside each temperature-controlled chamber of the TCF is provided by forced cooling and an internal temperature control system, i.e. the ambient temperature of each temperature-controlled chamber is automatically controlled. This feature eliminates the need for the user to heat the KB container before administering the KB to the patient. In a preferred embodiment, the temperature control mechanism is adapted to automatically switch to start before starting procedures at the beginning of the day.

Storage of KB and saline fluids

Storage of up to five HF containers in each of the temperature-controlled chambers provides the UTS for patient care for approximately 1 full treatment day. HF containers (as well as saline containers) can have various sizes. Container holders are adapted to the size of the containers used in them. Inside each temperature-controlled chamber, 4 KB containers filled with 500 ml KB and one container filled with 100 ml KB are preferably mounted. Access to one smaller HF container reduces the unnecessary loss of HF fluid at the end of the working day or between treatment breaks that are longer than the recommended usage time for HF containers. After piercing an HF container, the HF fluid stored in it has a limited shelf life, which leads to a recommended usage time, which is usually about 10 hours for conventional contrast agents. Thus, if a new 500 ml KB container was used for the final treatment at the end of the day, then the remaining fluid should be removed by the next morning. The ability to more efficiently control the loss of HF fluid is appropriate. Storage of a physiological saline container filled with 500 ml of physiological saline in each of the uncontrolled temperature chambers provides up to about half of the daily supply.

Storage of containers with many compartments filled with KB or saline solution frees the user from the need to constantly replenish the supply of fluid for the HF syringe during the day.

Automatic piercing of the container wall

In order for the UTSF to provide KB and saline fluids in the HF syringe, an SPTS needle 11 is inserted into the septum of the corresponding container. To accomplish this, the user must fix the SPTS needle 11 in the needle holder 10 on the UUTS 100 by means of a special mounting and fixing structure (guide groove 45, slide slide 55, pin 54, hole 44). The needle holder 10 is designed so that good axial alignment of the needle 11 with respect to the container wall is achieved. After the FCS is brought to its initial position, the containers in the chambers are replenished and the temperature-controlled chambers are brought to a temperature, the central electronic control system (SCEU) communicates with the automatic piercing device 12 to bring the holder 10 with the needle 11 into a vertically raised position, so the needle enters through the inlet point into the corresponding chamber and is fixed in the container wall. When this happens, the corrugated tube of silicone rubber 43 is destroyed, which allows the upper part 42 of the needle to fully enter the partition of the container. Using the position of the control sensors, the SCEU introduces the needle 11 at a predetermined distance into the container wall. Once this predetermined distance has been reached, the SCEU deactivates the automatic piercing device 12 to hold the needle holder 10 in a vertical position with respect to the container baffle.

The level of the fluid or the volume of fluid inside each of the punctured containers is monitored by sensors using feedback from the SCEC. As soon as the container becomes empty to a predetermined level called “Empty”, the SCEC communicates with the automatic piercing device 12 to move the needle holder 10 vertically downward, thereby removing the needle from the corresponding container. Further, this position of the container holder 8 is marked by the SCEU as “Empty”. By registering the status of containers “empty / full”, the SCEU can signal through the user interface, for example, when the last container in the HF camera is pierced or when all containers in the camera are empty.

The fluid control device (TCB) also includes a push button that allows the user to withdraw an automatic puncturing device to keep the system from puncturing another container. In addition, it allows an action that allows the user to manually select a small HF container at the end of daytime procedures to minimize the loss of HF fluid.

Automatic rotation of a rotating carousel with a free rotation option.

To index new HF containers so that they can be accessed and punctured, the rotation of a rotating carousel inside each temperature-controlled chamber is applied. To drive a gear motor, which in turn rotates (indexes) a rotating carousel in a predetermined position, use SCEU. The angular position of the rotating carousel is monitored using position sensors and SCEU. Therefore, at any given time, the SCEU confirms the position of each HF container. Thus, it is possible to determine at what angle a rotating carousel should be rotated in order to puncture a specific HF container.

After the user opens the temperature-controlled chamber door, the sensor is contacted by feedback from the SCEU. Further, the SCEU disengages (mechanically, electrically, electronically, or otherwise) the carousel drive device from engagement, so that the rotating carousel can no longer automatically rotate. This then allows the user to “freeze” the rotating carousel, providing it with a means of simply wrapping the rotating carousel to access each individual HF container in the fastest possible way.

In one embodiment of the invention, as shown in FIGS. 11, 12 and 13, rotation from the motor is transmitted through the gear of the motor 2 and the intermediate gear 4 to the main gear 2. The intermediate gear 4 is mounted on the first end of the mounting device 61, which is made hinged, moreover, the second end of the mounting device is movably connected to the intermediate lever 6. In this case, the intermediate lever 6 is connected to the door of the temperature-controlled chamber. When opening the door of the temperature-controlled chamber, as shown in Fig. 12, the intermediate lever 6 moves with the door and rotates the fastening device 61, so that the intermediate gear 4 disengages from the gear 3 of the motor and the main gear 2.

Container and recognition of a fluid transfer system (SPTS).

Containers adapted for use with a fluid management device (TCM), the so-called standard containers, have a radio frequency identification tag (RFI tag) (or other means of storing information) attached to them. This allows the SCEU to establish by querying the RFI reader (or a reader corresponding to another storage medium) connected to the SCEU at what time and in what position the container is replenished. This also allows the SCEU to carry out individualization by requesting an RFI tag if a non-standard container is placed in one of the container holders. If the container does not have an RFI tag, then the SCEU will recognize this, trying to interrogate the container until a connection is reached. This should be the case when the response of the SCEC to the user is visual and / or sound feedback on the mismatch and then blocking the location of the container, so that it cannot be punctured. This is an important safety feature to ensure that only the correct fluids and permitted containers are stored inside the PBX for delivery to the HF syringe.

Similarly, an RFI tag is also attached to each SPTS. Further, the SCEL will be able to request each SPTS submitted to ensure that it is approved for use.

Additionally, immediately after the SPTS needle pierces the container wall, the SCEU registers the SPTS as used and starts counting down the set time, which is recommended by the time the needle was used. After that, as soon as the recommended time of use of the needle, i.e. 24 hours have elapsed, the SCEU then provides feedback on the mismatch through a visual or audio means to warn the user about the need to replace the TTS before further use of the TTS.

Fluid characteristics

Data stored on the RFI tag of each container, such as the date of manufacture, etc., can be requested and saved using the RFI reader and the SEC. The data can then be transferred to the HF syringe or stored on a mobile storage device (i.e., a USB flash drive). This feature improves the ability of operational control.

Blocking timer

As soon as the HF container is punctured, the SCEU activates the recording timer and the corresponding HF container is registered by the SCEU as a punctured container. After the recommended time for using the HF container has expired and assuming that the corresponding HF container is not set to “empty”, the SCEU blocks the corresponding contrast medium (KB) and communicates with the automatic piercing device to remove the needle from the HF container . When the individual code stored on the RFID tag of the HF container is registered as used and / or expired after the specified time of use, being punctured, the user is no longer able to reuse the HF container or replenish this HF container in the future any temperature controlled chamber.

User interface device

In one embodiment, the information related to the HF syringe (fluid delivery levels / remaining volume, temperature) is displayed on the main screen of the HF syringe user interface device. This is achieved by direct data transfer between the UUT and the HF syringe. It is envisaged that information, such as temperature, which containers are empty / with expired usage time, etc., for each temperature-controlled camera should be displayed using light-emitting diodes (LED's) or the display screen on the UUT. This feature allows the user to directly control the fluid levels inside the TCB in relation to the corresponding camera. An inspection window is also placed on each of the chamber doors as a secondary user tool for visual control of fluid levels and containers requiring replenishment. The doors of the chambers give the user access to replenish the fluid, provided that the container inside the chamber is not punctured by this time. As soon as the door to the temperature-controlled chamber is opened, the carousel drive unit is disengaged to deprive the rotating carousel of the automatic drive while the user restores. The disengagement of the carousel drive device also allows the rotating carousel to rotate freely, so that the user can easily rotate the rotating carousel to access each individual container in a faster way. After closing the door of the temperature-controlled chamber, the carousel drive device is reengaged to automatically drive the rotating carousel during operation.

Data transfer

Two-way communication between the UUTS and the HF syringe is carried out by its own information platform for computer software. This gives the user the ability to control and track a number of TCF functions directly through the HF syringe interface. Data transfer between the PBX and the HF syringe can be carried out by a number of transmission media, including, but not limited to, the following:

- wired cable - USB, LAN, or the like,

- Bluetooth

- Wireless Network.

Leakage barrier

Under the rotating carousel and above the automatic piercing device of each temperature-controlled chamber, there is one manually removable drip collector 13, so that any leakage of KV fluid from previously punctured partitions of KV containers is intercepted within the installation.

In the embodiment of the CTS, described as an example, the SCEC has the ability to determine the positions of each container in the CTS, how long they were installed in the CTS, whether they were punctured earlier or not, or the fluid has expired in a specific container. In principle, this alleviates safety issues, such as re-piercing a used container or a container with an expired shelf life by the user.

A second exemplary embodiment of a fluid control system.

According to a second embodiment of a CTC described here, adapted to automatically dispense a preheated contrast medium (KB) and preheated saline solution into a CV syringe, for administration to a patient from a container filled with KB (i.e., KB container) or a container filled with saline (saline container).

15 and 16 show a second embodiment of a TCB. The UUTS200 of this embodiment comprises two cameras 201 and 202 attached to the frame of the housing. Both chambers 201, 202 are made with adjustable temperature. Each chamber 201, 202 accommodates a rotating carousel 205, 206. Five container holders are mounted on each rotating carousel 201, 202 to hold up to five KB containers 22 and up to five salt containers 23. Each chamber 201, 202 has a protective cover 203, 204 and is adapted for loading from above. Between both cameras 201, 202, a block 215 for SCEU is mounted on the frame of the housing together with a display 217 and a printer 220.

On the frame body, below each of the two chambers 201 and 202, a vertically moving needle holder 210 is vertically mounted. Said automatic puncturing device is arranged and oriented so that each needle holder 210 is adapted to align the needle 211 in axis with the axis of the container 22, 23, which must be punctured. A tube 218 connected to each needle 211 is adapted to transfer fluid from a punctured container to an HF syringe.
