Description

Automated closed blood collection device with blood diagnosis function {Automated blood collection device with blood diagnosis function}

The present invention relates to an automated closed blood collection device with a blood diagnosis function. More specifically, the present invention relates to an automated closed blood collection device that automatically analyzes and diagnoses the blood of a person being collected from the patient's side through a diagnosis unit connected to a tube, and determines the patient's condition based on the diagnosis results. This relates to an automated closed blood collection device that continuously monitors blood and has a blood diagnosis function.

A-line (arterial line) is a tool for observing the patient's hemodynamic condition such as blood pressure and pulse and collecting arterial blood. It consists of an arterial tube inserted into the artery, a tube connecting a saline solution bag, and a 3-way tube installed on the tube. It is made up of valves. Additionally, a transducer that converts the pulse into an electrical signal is connected to the tube. Electrical signals generated through the transducer are transmitted to the monitor, and doctors or nurses can check the patient's condition through the monitor.

Among patients admitted to the Intensive Care Unit (ICU), those receiving an A-line for monitoring arterial pressure have internal blood collected through the ductus arteriosus when performing a blood test. There are various methods of non-invasive blood collection, and usually, internal blood is collected after discarding about 5 cc of initial blood.

Initial blood is the blood that comes out from the start of blood collection, and internal blood is the blood after the initial blood collection. The reason for discarding the first blood is that accurate test results cannot be obtained because the first blood is likely to be mixed with heparin or diluted in saline even without heparin.

Noninvasive blood collection tests may be performed at least once a day or as many as every hour, dozens of times a day, depending on the patient's condition. Therefore, the amount of blood collected per day from critically ill patients ranges from as little as about 26ml to as much as 478ml or more. And because the initial blood is discarded each time a test is performed, the actual amount of blood lost from the patient is greater than this. Anemia is inevitable in patients admitted to the intensive care unit.

In order to solve this problem of blood collection (problem of discarding initial blood), Edwards Lifesciences' VAMP (hereinafter referred to as existing product) has been known. The existing product is a blood collection device that traps the initial blood in an external reservoir without discarding it, takes internal blood, and then transfuses the initial blood back into the body. However, conventional products have problems such as generating blood clots or causing a damping phenomenon in the transducer's arterial blood pressure monitoring.

Meanwhile, among the various methods for monitoring the condition of intensive care unit patients, blood diagnostic tests are included. For blood diagnostic tests, non-invasive blood collection is performed through an arterial or venous tube, or a syringe or blood collection tube.

However, in the case of intensive care unit patients who require continuous blood collection, in most cases, non-invasive blood collection is performed because the patient is equipped with an A-line or C-line. The collected blood is transferred to a diagnostic laboratory for a blood test or is diagnosed using a point-of-care testing device (POCT).

However, in the case of critically ill patients, as explained above, a blood test must be performed dozens of times a day, depending on the patient's condition. To conduct a blood test, each time, a blood collection syringe is connected to the blood collection port to draw blood. Transporting the collected blood to a testing device is a very cumbersome task. Moreover, when there are multiple critically ill patients, the patients' blood must be separated so that they do not mix, which is also something that needs to be taken care of.

Additionally, since the method of blood collection and diagnosis described above involves analysis of the sampled blood itself, it cannot provide information on changes in the patient's condition. For example, it is not possible to tell how the patient's condition is changing compared to the time of the previous examination, how much it has changed, and the amount and speed of change.

The present invention provides an automated closed blood collection device with a blood diagnosis function that simultaneously analyzes and diagnoses the patient's blood, provides quick and accurate diagnostic results, and can continuously monitor changes in the patient's condition. There is a purpose.

The automated closed blood collection device with a blood diagnosis function of the present invention as a means of solving the problem for achieving the above object includes a diagnostic module for analyzing and diagnosing arterial blood induced into the arterial duct connected to the patient's arterial blood vessel; It is connected to the diagnostic module and has an output unit that receives and outputs the results analyzed by the diagnostic module.

In addition, a guide tube connected to the ductus arteriosus through a switching valve is further included, and the diagnostic module includes; It is installed in the arterial duct or guide tube.

Additionally, a blood collection valve providing a blood collection passage is further installed in the arterial duct, and a sampling valve is further installed in the arterial duct or guide tube to guide arterial blood in the arterial duct or guide tube to a diagnostic module.

In addition, the sampling valve is an electromagnetic valve that operates by an electric signal or can be manually operated when there is no electric signal, and further includes a controller for driving the electromagnetic valve.

Additionally, a metering pump is provided between the sampling valve and the diagnostic module and is controlled by the controller to supply arterial blood to the diagnostic module.

In addition, the output unit; It includes a monitor that continuously displays the amount of change in the analysis results at each analysis point.

In addition, the automated closed blood collection device with another blood diagnosis function of the present invention as a means of solving the problem for achieving the above object is mounted on a venous tube connected to the patient's venous blood vessel, and analyzes and diagnoses venous blood guided into the venous tube. Diagnostic module; It is connected to the diagnostic module and has an output unit that outputs the results analyzed by the diagnostic module.

In addition, the venous tube further includes a blood collection valve that provides a blood collection passage, and a sampling valve is installed on the upstream or downstream side of the blood collection valve to guide venous blood inside the venous tube to the diagnostic module.

In addition, the sampling valve is an electromagnetic valve operated by an electric signal, and further includes a controller for driving the electromagnetic valve.

Additionally, a metering pump is provided between the sampling valve and the diagnostic module, and is controlled by the controller and delivers venous blood to the diagnostic module.

Additionally, the output unit; It includes a monitor that continuously displays the amount of change in the analysis results at each analysis point.

The automated closed blood collection device with the blood diagnosis function of the present invention as described above performs analysis and diagnosis of blood simultaneously in one stop through a diagnostic unit connected to a tube, so diagnosis is quick and accurate, and it is possible to perform blood collection through a syringe. The problem can be completely resolved.

In addition, it continuously monitors changes in the patient's condition based on the results of the blood test, helping doctors make accurate medical decisions.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the attached drawings.

The automated closed blood collection device of this embodiment has a diagnostic unit that analyzes and diagnoses the blood induced into the arterial or venous duct installed in the patient's body, as it is inside the ductus arteriosus or venous duct, rather than extracting it with a syringe. Previously, blood was collected one by one with a syringe and the collected blood was moved to an analysis device to perform tests, but this inconvenience has been eliminated.

In addition, 'arterial duct' and 'venous duct' in this description may refer to a kit including a pressure transducer and tubing, excluding the part (catheter) connected to the patient.

The basic configuration of the present invention includes a diagnostic module for analyzing and diagnosing arterial blood induced into the arterial duct connected to the patient's arterial blood vessel; It is connected to the diagnostic module and has an output unit that receives and outputs the results analyzed by the diagnostic module.

In addition, the basic configuration of another example of the present invention includes a diagnostic module mounted on a venous tube connected to a patient's venous blood vessel and analyzing and diagnosing venous blood guided into the venous tube; It is connected to the diagnostic module and has an output unit that outputs the results analyzed by the diagnostic module.

Figure 1 is a diagram showing an example of an automated closed blood collection device with a blood diagnosis function according to a first embodiment of the present invention installed in an arterial duct, and Figure 2 is a diagram showing an example of an automated closed blood collection device with a blood diagnosis function shown in Figure 1. This is the configuration diagram.

The automated closed blood collection device 10 with a blood diagnosis function according to this embodiment includes a diagnostic unit 40 in a so-called preservation blood collection device, which collects the patient's internal blood and returns the initial blood back to the body. It has an applied structure.

By applying the diagnostic unit 40 to the preservation blood collection device, the patient's blood diagnosis can be performed not only irregularly but also at certain times, enabling continuous patient monitoring through automation of blood collection and diagnosis. Moreover, by continuously displaying the change in blood analysis results at each analysis time, it is possible to effectively identify trend information on the patient's condition.

As shown, the closed blood collection automation device 10 according to this embodiment includes a transfusion bag 13, an arterial tube 21, a blood collection valve 23, a switching valve 25, an induction tube 27, and a pump ( 35), a pressure accumulation chamber (37), a check valve (39), and a diagnostic unit (40).

The infusion bag 13 is a plastic bag containing saline water inside and is provided with a first port 13a and a second port 13b at the lower end. The pressure inside the IV bag 13 is maintained at about 300 mmHg. The fluid bag (13) is connected to the patient's arterial blood vessel (101) through the arterial duct (21).

In order to adjust the internal pressure of the IV bag 13 as needed, a manual compressor 15 can be connected to the IV bag 13. The manual compressor 22 is a general compression means that the user handles by holding it with his or her hand. Additionally, the saline solution in the IV bag 13 contains heparin. Heparin is pre-injected through port A or B. The infusion bag (13) is mounted on the upper side of the pole (11) like a normal saline solution bag.

The arterial duct 21 is a vinyl tube that connects the patient's arterial blood vessel 101 and the first port 13a. The inside of the arterial duct (21) is filled with saline water, and the water pressure of the saline solution and the pressure inside the IV bag (13) are transmitted to the distal end.

The arterial duct 21 is composed of a catheter 21b, a proximal tube 21d, and a distal tube 21e. The catheter 21b is a tube equipped with a blood collection needle 21a at one end, and the other end is connected to the blood collection valve 23. When the blood collection needle 21a penetrates the arterial blood vessel 101, arterial blood flows out through the blood collection needle 21a and into the catheter 21b.

The proximal tube 21d connects the blood collection valve 23 and the switching valve 25, and the distal tube 21e is a flexible tube connecting the switching valve 25 and the first port 13a. The proximal tube 21d communicates with the catheter 21b through the blood collection valve 23, and the distal tube 21e communicates with the proximal tube 21d through the switching valve 25.

Ultimately, the saline solution in the IV bag 13 passes through the first port 13a, the distal tube 21e, the switching valve 25, the proximal tube 21d, the blood collection valve 23, and the catheter 21b. It reaches the blood vessel 101.

The blood collection valve 23 is a general manual 3-way valve that opens and closes the passage of the ductus arteriosus 21. When the ductus arteriosus is opened, saline solution or blood can flow inside the ductus arteriosus, and when the ductus arteriosus is blocked, the flow path of saline solution or blood is blocked.

Blood collection is also possible through the blood collection valve (23). Blood (out of the ductus arteriosus) can be extracted by connecting the syringe 51 to the blood collection port (not shown) of the blood collection valve 23 with the ductus arteriosus blocked.

The switching valve 25 is also a manual 3-way valve with the same configuration as the blood collection valve 23. The switching valve 25 connects the proximal tube 21d, the distal tube 21e, and the guide tube 27. Through the switching valve 25, the proximal tube 21d and the distal tube 21e can be connected and the guide tube 27 can be blocked. Additionally, the proximal tube (21d) and the guide tube (27) can be connected and the distal tube (21e) can be blocked.

The switching valve 25 may have one body with the transducer 31. However, the switching valve (25) can be separated from the transducer (31) and installed separately.

The transducer 31 receives the pulse signal from the patient's artery transmitted using saline solution as a medium, converts it into an electrical signal, and transmits the converted electrical signal to the external patient monitor 33. Since the structure and function of the transducer 31 itself are general, description thereof will be omitted.

Meanwhile, the guide tube 27 is a flexible tube whose one end is connected to the switching valve 25 and the other end is connected to the second port 13c of the transfusion bag 13. The inside of the guide tube 27 is filled with saline solution. The length of the guide tube 27 may also vary depending on need.

The guide tube 27 is one tube, and for convenience of explanation, it can be divided into a first guide tube 27a and a second guide tube 27b based on the pump 33. The first guide tube (27a) is the part between the switching valve 25 and the pump 35, and the second guide tube (27b) is the part between the pump 35 and the second port (13c).

A pump 35, a check valve 39, and a pressure accumulation chamber 37 are installed in the induction tube 27.

The pump 35 is a fluid transfer means that operates when the proximal tube 21d and the guide tube 27 are connected to transfer fluid (saline solution, initial blood) to the transfusion bag 13. The pump 35 is a peristaltic pump that presses the outer peripheral surface of the guide tube 27 in the longitudinal direction and moves the fluid inside the guide tube in the longitudinal direction of the guide tube.

The check valve 39 is installed between the second port 13c and the pressure accumulation chamber 37, and prevents compressed air inside the pressure accumulation chamber 37 from penetrating into the transfusion bag 13. The saline solution in the IV bag (13) can go down to the pressure accumulation chamber (37) through the check valve (39).

The pressure accumulation chamber is a closed container that accumulates the pressure of the fluid flowing into it by operating the pump 33. The pressure accumulated in the pressure accumulation chamber 37 serves to push the fluid in the guide tube 27 when the pump 35 rotates in reverse and the fluid in the guide tube 27 moves toward the proximal tube 21d.

The diagnosis unit 40 will be described later.

The operation of the preservation blood collection device having the above configuration is performed as follows. Before collecting blood through the blood collection valve 23, the catheter 21b, the proximal tube 21d, and the proximal tube 21d and the distal tube 21e of the ductus arteriosus 21 are connected, and the inside of the ductus arteriosus 21 is connected. is filled with saline solution containing heparin.

In addition, the pressure inside the arterial duct 21 and the pressure of the arterial blood vessel are equalized through a separate zeroing process. The heartbeat is transmitted to the transducer 31 using arterial blood and saline solution inside the proximal tube 21d as a medium, and the transducer 31 converts the blood pressure and pulsation signals into electrical signals and transmits them to the patient monitor 33. .

To collect blood in the above state, switch the switching valve 25 to communicate with the proximal tube 21d and the guide tube 27, and at the same time operate the pump 33 to connect the proximal tube 21d and the guide tube 27. ) Pull the saline solution filled in and move it to the infusion bag (13). When the saline solution is pulled and transported, the blood inside the arterial blood vessel 101 flows out of the arterial blood vessel, moves along the saline solution, and passes through the blood collection valve 23.

As the above process is performed, initial blood and internal blood are induced into the proximal tube 21d and the guide tube 27. ‘Initial blood’ is blood that has been in contact with saline solution containing heparin. In other words, blood diluted with saline and mixed with heparin is initial blood. ‘Internal blood’ is blood collected after the initial blood has been drained.

If the internal blood has passed the blood collection valve 23 through the above process, the blood collection valve 23 is blocked and the syringe 51 is connected to collect the internal blood.

When blood collection is completed, open the blood collection valve (23) again and rotate the pump (33) in reverse. As the pump rotates in reverse, the pulled initial blood and saline move to the catheter (21b), and the internal blood and initial blood are retransfused into the arterial blood vessel (101).

If the internal blood and initial blood have flowed back into the arterial blood vessel 101, the switch valve 25 is operated to connect the proximal tube 21d and the distal tube 21e, and the guide tube 35 is blocked to proceed with the blood collection process. conclude.

Meanwhile, the diagnostic unit 40 samples blood through the arterial duct 21 and analyzes and diagnoses the sampled blood. The operation of the diagnostic unit 40 is performed regardless of blood collection through the blood collection valve 23 described above, but with internal blood passing through the sampling valve 41.

For reference, when a separate automatic blood collection tube is connected to the sampling valve 41, blood can be collected separately from the diagnostic unit, then the blood collection tube can be pulled out and sent to an examination room to perform a complex examination.

The diagnostic unit 40 can be installed on the upstream or downstream side of the switching valve 25, and is installed on the upstream side in FIG. 2.

The diagnostic unit includes a sampling valve 41, a diagnostic module 43, and an output unit. The sampling valve 41 is a valve that guides a portion of the internal blood (arterial blood) passing through the proximal tube 21d to the diagnostic module 43. Since internal blood can be sampled using the sampling valve 41, syringe blood collection for blood analysis and diagnosis is unnecessary.

The diagnostic module 43 is a diagnostic device that analyzes and diagnoses internal blood. The diagnostic module 43 itself is general. The test items of the diagnostic module 43 include hematocrit and hemoglobin, which are hemodynamic measurement elements such as Ph, PO2, PCO2, and TCO2b, corresponding to arterial blood gas testing, and Sodium (Na), Potassium (K), and Chloride (corresponding to electrolyte testing). Cl), Ionised Calcium (iCa), Glucose (Glu), Urea Nitrogen (BUN), Creatinine (Crea), Lactate, etc. Of course, test items can be added or subtracted depending on the disease or patient.

The diagnostic module 43 performs diagnosis by mixing diagnostic reagents with internal blood according to a general process. Liquid mixed with diagnostic reagents and internal blood is disposed of later.

The information analyzed in the diagnostic module 43 is transmitted to the output unit. The output unit is a CBM (Continuous Blood Monitoring) device 45 that receives and outputs the results analyzed by the diagnostic module. The CBM device 45 continuously displays the amount of change in the analysis results by the diagnostic module 43 at each analysis time. The display contents of the CBM device 45 can be expressed in graphs, tables, or various graphic methods. Additionally, the display contents can be displayed by connecting to another monitor by wire or wirelessly.

Through the CBM device 45, it is possible to monitor the amount of change in the patient's condition compared to the time of the previous examination, and based on this data, the doctor's treatment plan can be adjusted in more detail.

Reference numeral 47 is a wireless communication unit. The wireless communication unit 47 transmits the information output from the CBM device 45 to the external cloud 61, data server 63, or terminal 65. The terminal 65 may be a smartphone carried by the doctor.

FIG. 3 is a diagram showing a modified example of the automated device shown in FIG. 2.

As shown in FIG. 3, the diagnostic unit 40 may be installed in the first guide tube 27a. The sampling valve 41 delivers a portion of the internal blood that has risen to the first guide tube 27a to the diagnostic module 43.

FIG. 4 is a diagram for explaining another modified example of the automation device 10 shown in FIG. 3.

The closed blood collection automation device 10 with blood diagnosis function shown in FIG. 4 has a configuration that allows blood collection, analysis, and diagnosis to be performed on its own. In other words, as long as the administrator (doctor or nurse) enters the test cycle considering the patient's condition, it automatically operates to collect blood and analyze it for diagnosis when the entered time arrives. For example, if the administrator sets the blood test cycle to one hour, blood is collected and analyzed for diagnosis at hourly intervals.

For this purpose, an input unit 73 and a controller 71 are additionally installed, an electronic sampling valve 55 is installed instead of the manual sampling valve 41, and an electric switching valve 53 is installed instead of the manual switching valve 25. The electronic valve is a solenoid valve with a built-in coil and operates by receiving a control signal from the controller 71.

The sampling valve 55 takes a portion of the blood inside the proximal tube 21d in response to a signal from the controller 71 and sends it to the diagnostic module 43. In addition, the switching valve 53 operates simultaneously with the operation of the pump 35, allowing the fluid inside the ductus arteriosus to move to the guide tube 27 or blocking the ductus arteriosus and the guide tube.

In addition, the metering pump 57 is installed between the sampling valve 55 and the diagnostic module 43, and operates when the sampling valve 55 is opened to guide the required amount of blood to the diagnostic module 43. do. As described above, the supply flow rate of the metering pump 57 is preset by the input unit 73. When blood collection by the metering pump (57) is completed, the sampling valve (55) automatically closes.

The input unit 73 is a part where various information required for blood collection is input. For example, the time interval between blood collection or the amount of blood collected at one time of blood collection is entered. The controller 71 controls the pump 35, the switching valve 53, the sampling valve 55, and the metering pump 57 according to the conditions input through the input unit 73.

FIG. 5 is a diagram illustrating another modified example of the automated device of FIG. 4.

The closed blood collection automated device 10 shown in FIG. 5 has the same configuration as the automated device shown in FIG. 4, and the multi-faceted diagnostic unit 40 is installed in the first guide tube 27a. The configuration and operation of the diagnostic unit 40 are as described in FIG. 4.

Figure 6 is a diagram showing an example in which an automated closed blood collection device with a blood diagnosis function according to a second embodiment of the present invention is installed in a venous tube.

Reference numbers that are the same as those described above are the same members with the same function, so repeated description thereof will be omitted.

The non-invasive sampling device 10 with diagnostic function according to the second embodiment includes an IV bag 13, a venous tube 29, a diagnostic unit 40, and an output unit. The venous tube is a central venous tube, which is connected to the venous blood vessel 103 and is a flexible tube extending in the longitudinal direction, and has a fluid bag 13 at the end. The venous tube is equipped with a blood collection valve (23). The composition and method of use of the venous tube itself are the same as a general venous tube.

The diagnostic unit 40 analyzes and diagnoses venous blood induced into the venous tube 29 and includes a sampling valve 55, a metering pump 57, and a diagnostic module 43. The sampling valve 55 and the metering pump 57 are controlled by the controller according to conditions input through the input unit 73.

However, the diagnostic unit 40 can be implemented manually as well. In other words, the sampling valve 55 can be applied as a manual 3-way valve, and the metering pump 57 can be omitted. Of course, the unit cost of the blood collection device can be significantly reduced when implemented manually.

Venous blood that passes through the sampling valve 55 and the metering pump 57 enters the diagnostic module 43 and is analyzed. The analyzed results are delivered to the output unit, that is, the CBM device 45, so that doctors or nurses can immediately understand them on site.

Above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention.
