Description

Technical Field

[0001] The utility model relates to the field of innovative medical devices, in particular to an innovative intelligent external ventricular drainage (EVD) system and a liquid-electric dual-purpose locking connector. Background Art

[0002] External ventricular drains (EVD) are one of the most commonly used treatment techniques in neurosurgery. Specifically refers to the continuous drainage of cerebrospinal fluid in the ventricles or lumbar cistern into an external closed system. External ventricular drains (EVD) are used to manage patients who require cerebrospinal fluid drainage to control increased intracranial pressure associated with craniocerebral injury, subarachnoid hemorrhage, acute hydrocephalus secondary to cerebral aqueduct obstruction, posterior cranial fossa tumors, or purulent meningitis. Especially for patients with neurosurgical emergencies such as acute hydrocephalus and intraventricular hemorrhage. In cases of acute hydrocephalus and / or increased intracranial hypertension due to various pathologies, it is generally considered a life-saving treatment.

[0003] However, while the procedure is quick and relatively simple, it is not without the risk of complications such as infection (such as meningitis and ventriculitis), bleeding along the way, and improper placement or blockage of the catheter itself.

[0004] The existing external ventricular drainage products do not make intelligent management transformation for the patient's drainage process. They still rely on the traditional way, relying on medical staff to observe regularly and check whether the drainage catheter is blocked, and whether the color and clarity of the cerebrospinal fluid have changed. However, during the drainage period, it is necessary to identify whether the patient has intracranial infection. Routine biochemical and bacteriological examinations of cerebrospinal fluid are required, including: cerebrospinal fluid cell count, protein, glucose and chloride ion levels, cerebrospinal fluid smear analysis, and bacterial culture.

[0005] The existing design CN113577518A relates to a cerebrospinal fluid drainage device, specifically to a light-controlled constant-speed cerebrospinal fluid drainage device and a drainage system, and relates to the technical field of medical appliances, in order to solve the problems existing in the prior art of the length of cerebrospinal fluid drainage time. The daily drainage volume is closely related to complications such as brain hernia, hydrocephalus, subdural effusion / hemorrhage, and intracranial infection. The prior art believes that it is safer to set a low flow rate in the early stage of drainage and to appropriately increase the flow rate in the later stage, which lacks objective accuracy. Therefore, there is a lack of a drainage device that can accurately control the drainage speed. The device includes a drainage tube and a drainage component and a control switch connected to the drainage tube, wherein: the drainage component includes a pump body and a spectral detection element arranged inside the pump body, and the spectral detection element is used to identify the color of the liquid in the drainage tube; the pump body, the spectral detection element, and the control switch are all connected to the control unit, and the control switch is connected to the pump body to control the drainage speed of the pump body. The utility model is used to accurately control the drainage speed of cerebrospinal fluid. CN113577518A does not disclose the overall configuration of the EVD system of the present utility model, nor does it disclose the external drainage-sensing assembly and external drainage monitoring equipment of the present utility model.

[0006] The existing design CN114531852A involves monitoring of specific body fluids (such as peritoneal dialysis fluid) of patients, especially monitoring the photoelectric characteristics of the fluid to determine the turbidity / turbidity of the fluid to determine whether the patient is infected. CN114531852A does not disclose the overall configuration of the EVD system of the utility model, nor does it disclose the external drainage-sensing component and external drainage monitoring device of the utility model.

[0007] The existing technical solutions have problems and disadvantages as listed below:

[0008] (1) The management of extraventricular drainage is a nursing responsibility. During the patient's drainage treatment, the nursing staff needs to check the patient's drainage catheter from time to time, and confirm whether the drainage catheter is blocked or bleeding by visual observation and squeezing. However, the existing system is not only time-consuming and labor-intensive, but also increases the maintenance cost of nursing staff. It is also likely to delay discovery and treatment delays, causing irreversible harm to patients, and the treatment time and cost will also increase accordingly.

[0009] (2) During drainage, routine biochemical and bacteriological examinations of cerebrospinal fluid are required to identify whether the patient has intracranial infection, including: cerebrospinal fluid cell count, protein, glucose and chloride ion levels, cerebrospinal fluid smear analysis, and bacterial culture. These existing methods require sampling at the proximal port of the external ventricular drainage system (closest to the head), and sampling must be performed strictly in accordance with aseptic techniques. When sampling, suction is very slow (1ml / min). If any resistance is encountered, sampling should be stopped and the doctor should be notified immediately. Bacterial culture takes a long time, usually more than 72 hours to produce results, so it is easy to miss the best time for treatment.

[0010] Therefore, the industry needs an improved external ventricular drainage (EVD) system and innovative components thereof to alleviate or overcome the defects of the prior art and achieve more beneficial technical effects and technical progress.

[0011] The cerebrospinal fluid drainage system of the utility model can be used, for example, after cerebrospinal fluid drainage surgery, and can be adapted to cerebrospinal fluid external drainage devices / components on the market. It can perform real-time, dynamic, and continuous monitoring and management of patients during the drainage period, so as to identify the risks of complications such as intracranial infection, pipeline blockage, and bleeding as early as possible.

[0164] Intelligent external ventricular drainage system

[0165] Figure 1A FIG. 1 is a schematic diagram of the overall configuration of an intelligent external ventricular drainage system 10 according to an embodiment of the present invention. Figure 1A As shown, the intelligent external ventricular drainage system 10 according to this embodiment may include:

[0166] A ventricular end drainage catheter 300, one end of which can be inserted into the patient's brain, and the other end (external end) can be directly connected or connected to the ventricular end external drainage catheter 220 of the external drainage-sensing assembly 200 via a connector, such as a hydraulic-electric dual-use locking connector 400;

[0167] Part of the components thereof is preferably a disposable external drainage-sensing assembly 200, one end of which is fluidically connected to the ventricular end drainage catheter 300 via the ventricular end external drainage catheter 220, and the other end is connected to the collection device 600 via the collection end external drainage catheter 230 (for example, connected via the collection end drainage catheter 500, or directly connected);

[0168] Preferably, a reusable external drainage monitoring device 100 is operably connected to the external drainage-sensing assembly 200, and is used to process the sensor data / signals from the external drainage-sensing assembly 200, including A / D or D / A conversion, signal conditioning, signal transmission, signal control, data processing and storage, signal threshold setting, alarm, signal display, etc.; the external drainage monitoring device 100 can be configured to receive / interact data with the patient-side continuous blood glucose monitoring module 800 by wireless communication, for example, and can also be configured to perform wireless communication and data transmission / interaction with an external device 700, and the type and number of the external device 700 are determined according to the application and functional requirements, such as but not limited to a display, a computer, an Internet device, a monitoring device (such as an ICU monitoring device), a mobile phone, a tablet, a hospital terminal, etc.;

[0169] The collection device 600 can be connected to the external drainage-sensing assembly 200, for example, directly or via the collection end drainage catheter 500, to the collection end extracorporeal drainage catheter 230 of the external drainage-sensing assembly 200. The cerebrospinal fluid (CSF) external drainage fluid received by the collection device 600 can be used for further analysis, monitoring, sampling, storage, or for any required legal and compliant medical purpose.

[0170] Figure 1B yes Figure 1A The schematic diagram of an exemplary configuration of the ventricular end drainage catheter 300 at the patient end of the intelligent external ventricular drainage system 10 is shown, showing the connector 300B of the ventricular end drainage catheter 300, which can be directly connected to the drainage tube of the external drainage-sensing assembly 200, or can also be connected via a connector. The connector can be a common Luer connector or a connector that complies with a specific standard (such as ISO-80369-6), or a hydraulic and electrical dual-use locking connector 400 can be used, as described in detail below.

[0171] The end of the ventricular drainage catheter 300 inserted into the patient's brain can be a simple lumen, or a bougie 300A can be configured at the end inserted into the patient's brain. An example of the bougie 300A can be an intracranial monitoring bougie or bougie assembly that can sense intracranial pressure and / or intracranial temperature disclosed in the Chinese application (application number 2023102231207) filed by the same applicant on March 9, 2023, "Artificial Intelligence Assisted Intracranial Monitoring System and Bougie Assembly", or it can be an intracranial monitoring bougie or bougie assembly that can sense intracranial pressure and / or intracranial temperature disclosed in the PCT application (application number PCT / CN2023 / 108432) filed by the same applicant on July 20, 2023, "Artificial Intelligence Assisted Intracranial Monitoring System and Bougie Assembly", and the contents related to the bougie or bougie assembly in these two applications are incorporated into this application by reference, just as described in this application.

[0172] In the case where a bougie is not configured in the lumen of the ventricular end drainage catheter 300 inserted into the brain skull, if it is necessary to monitor / measure the patient's intracranial pressure (ICP), it can also be monitored / detected by the pressure sensor (module) configured by the external drainage-sensing assembly 200 (whose configuration is described in detail below). In this case, in order to make the measured intracranial pressure data as relatively accurate as possible, the valve on the side of the external drainage catheter 230 at the collection end of the external drainage-sensing assembly 200 should be closed first, so that the pressure in the lumen of the external drainage-sensing assembly 200 is as close to equal as possible to the patient's intracranial pressure (ICP) (reaching a balance, or even equal).

[0173] For the intelligent external cerebral drainage system 10, the core configuration is the external drainage-sensing assembly 200 and the external drainage monitoring device 100. Other configurations of the intelligent external cerebral drainage system 10 can be changed, increased or decreased according to needs and applications, which are all within the scope of the present invention.

[0174] External drainage monitoring equipment

[0175] Figure 2A yes Figure 1A The schematic three-dimensional view of the overall structure and configuration of an embodiment of an external drainage monitoring device 100 of an intelligent external ventricular drainage system is shown, wherein the external drainage monitoring device 100 is already together with the external drainage-sensing assembly 200. Figure 2B yes Figure 2A The schematic front view of the schematic overall structure and configuration of the external drainage monitoring device 100 is shown, wherein the flip cover of the external drainage monitoring device 100 has been opened to further display the internal configuration of the external drainage monitoring device 100 and the external drainage-sensing assembly 200 assembled therewith.

[0176] As shown in the figure, a display screen 110 connected to the MCU 180 is provided on the main body of the external drainage monitoring device 100, for example, on the upper part of the front of the main body, for displaying monitoring information. The displayed information varies according to the configuration, function and application of the external drainage monitoring device 100, including but not limited to pressure value, pressure waveform, flashing alarm, etc. A flip cover 120 that can be flipped open and closed is provided at the lower part of the front of the main body of the external drainage monitoring device 100. The external drainage-sensing assembly 200 (described in detail below) is integrated and assembled in the lower part, and the ventricular end external drainage catheter 220 and the connector 220A are exposed on one side, and the collection end external drainage catheter 230 and the connector 230A are exposed on the other side. A back clip (fixing clamp) 130 may be provided on the back of the main body of the external drainage monitoring device 100, which is used to clamp and install the external drainage monitoring device 100 on the required position / component. The connector 220A and the connector 230A may be standard Luer connectors, or connectors that comply with other standards such as ISO80369-6, and the like.

[0177] Figure 2B yes Figure 2A The front projection diagram of the external drainage monitoring device 100 is shown, in which the flip cover 120 has been opened, showing the internal configuration of the external drainage monitoring device 100 and more details of the external drainage-sensing assembly 200 assembled therewith. As shown in the figure, the external drainage monitoring device 100 (for example, on the front of the main body) can also be provided with a power indicator light 150 for indicating whether the DC power supply is connected, and an alarm light 160 for issuing an alarm signal in an emergency state, for example, when a set relevant threshold value is exceeded. The flip cover 120 can be flipped open and closed, and an example thereof is a magnetic suction type, that is, it is fixed by magnetic suction when closed and can be easily opened. Some of the beneficial effects of setting the flip cover 120 are that the spectral sensor 260 always monitors the color change of the drainage fluid in the same (dark) environment, reducing the influence of other external factors; at the same time, it prevents the external drainage-sensing assembly 200 from being accidentally pressed, resulting in looseness or poor contact. The connection method of the flip cover is not limited to snaps, magnetic suction, etc.

[0178] In addition, on the inner side of the flip cover 120, corresponding to the position for providing working lighting for the spectrum sensor 260 when closed, an LED light source 140 that cooperates with the spectrum sensor 260 can be provided to provide a working light source for the sensing work of the spectrum sensor 260. There are many benefits to arranging the working light source 140 of the spectrum sensor 260 on the flip cover 120, including saving costs for the external drainage-sensing assembly 200 containing disposable components (so that the working light source 140 can be discarded together), more convenient and reliable assembly / use, etc. Of course, it can be understood by those skilled in the art that although this is a preferred solution, the working light source 140 can also be arranged at other suitable positions, including being integrated into the spectrum sensor 260. Although not required, a magnetic interface seat 170 can also be arranged at a position on the external drainage monitoring device 100 that is connected to the base 210 of the external drainage-sensing assembly 200, so that the base 210 can be arranged as a magnetic base, as described in further detail below. According to a preferred example, the spectral sensor 260 can be configured to directly input digital signals without the need for a signal conditioning circuit, so that the spectral sensor 260 can be directly connected to the host circuit / MCU of the external drainage monitoring device 100 with a shorter communication / circuit distance. The advantage of such a configuration is that the shorter the physical communication distance between the spectral sensor 260 and the host circuit / MCU, the more stable the signal transmission, making the final sensor data output more accurate.

[0179] Figure 2C yes Figure 2A The schematic left side view of the external drainage monitoring device 100 further schematically illustrates the configuration of the rear portion and the flip cover of the external drainage monitoring device 100, and how to install the external drainage-sensing assembly 200. As shown in the figure, the flip cover 120 is flipped open along the direction indicated by the arrow R1, and then the base 210 of the external drainage-sensing assembly 200 is turned inward (i.e., the bottom communication interface 210B of the base 210 faces the outside). Figure 2C The left side shown in FIG. 1 is plugged into and matched with the corresponding interface on the external drainage monitoring device 100 along the direction indicated by the arrow R2, thereby completing the assembly of the two.

[0180] Figure 2D yes Figure 2A The schematic diagram of an example of the host (mainboard) circuit and configuration of the external drainage monitoring device 100 schematically shows an example of the architecture and configuration of the host circuit of the external drainage monitoring device 100. Figure 2DAs shown, the host circuit of the external drainage monitoring device 100 can be configured with a microprocessor (MCU) 180 preferably with wireless control. The pressure sensor module 240 can be connected to the microprocessor (MCU) 180 through the pressure sensor interface and via the signal conditioning circuit, the glucose sensor module 250 can be connected to the microprocessor (MCU) 180 through the glucose sensor interface and via the signal conditioning circuit, and the spectrum sensor 260 (which has integrated the digital output circuit of the A / D conversion function) and the LED light source 140 equipped therewith can be directly connected to the microprocessor (MCU) 180 through the spectrum sensor interface and the LED light interface respectively without the need for an additional signal conditioning circuit, thereby transmitting the sensed data / signal to the MCU 180 for processing. In addition, the MCU 180 can also transmit the set display data / parameters to the display screen 110 via the serial port display screen interface to display the required information / parameters. In addition, the MCU 180 processing can also selectively perform data transmission / data interaction with the external blood glucose monitoring module, the terminal transmitting / receiving circuit, and other external devices, such as in the form of wireless communication (including but not limited to Bluetooth, WIFI, etc.).

[0181] Figure 2E yes Figure 2A FIG. 1 is a schematic diagram of the overall system architecture of the external drainage monitoring device 100. Figure 2EAs shown, the externally drained cerebrospinal fluid (CSF) can be drained to the pressure sensor module 240 / glucose sensor module 250 of the external drainage-sensing assembly 200 extending into its pipeline outside the patient's body. The pressure sensor module 240 / glucose sensor module 250 transmits the sensed fluid pressure signal / glucose signal in the pipeline to the MCU 180 of the external drainage monitoring device 100 outside the patient's body via the signal conditioning circuit. The externally drained cerebrospinal fluid (CSF) can also be further drained to, for example, a spectral sensor 260 (which can cooperate with the LED light source set at the flip cover of the external drainage monitoring device 100 when working) installed outside the lumen of the external drainage-sensing assembly 200 and not in substantial contact with the cerebrospinal fluid in its tube for detection. The spectral sensor 260 (which can integrate digital output) can directly transmit the sensed color signal of the cerebrospinal fluid (CSF) to the MCU 180. The MCU 180 can also receive blood glucose data from the continuous blood glucose sensor (CGM) 800 in a wireless manner for processing. In addition, the MCU 180 may transmit the received and / or processed data / signals to a display module such as the display screen 110 to display at least one of the following items: extracorporeal CSF pressure value and pressure waveform, CSF pressure waveform attenuation, CSF color, CSF glucose concentration, blood glucose concentration, CSF glucose concentration / blood glucose concentration ratio, etc. In addition, the MCU 180 may also be configured to communicate with an external device, such as a remote terminal (computer, Internet terminal, ICU monitoring terminal, mobile phone, tablet, etc.), for example, through a communication module, and the communication module may be a wireless communication module, such as Bluetooth, WiFi, etc., which may be configured on the external drainage monitoring device 100 or on other locations / devices, all of which are within the scope of the present invention.

[0182] External drainage-sensing component

[0183] Figure 3A yes Figure 1A The schematic three-dimensional view of the overall structure and configuration of one embodiment of an external drainage-sensing assembly 200 of an intelligent external ventricular drainage system is shown. Figure 3B yes Figure 3A The external drainage-sensing assembly 200 is shown as a schematic three-dimensional view after being flipped 180 degrees, with the structure and configuration of the base 210 thereof being highlighted. Figure 3C yes Figure 3A-3B The schematic cross-sectional view of the external drainage-sensing assembly 200 along its central longitudinal axis shows its overall structure and the configuration and installation of its components.

[0184] As shown, this embodiment of the external drain-sensing assembly 200 may include:

[0185] (1) a base 210;

[0186] (2) a pressure sensor module 240, which is snap-fitted, for example, in a sliding-in manner (because it may make a clicking sound when sliding into the snap-fit, it may also be referred to as a sliding-in fit, a snap-fit, etc.) at one end of the base 210, and is used to sense CSF pressure parameters / signals in the pipeline of the external drainage-sensing assembly 200, such as pressure value, pressure waveform, pressure waveform attenuation, pressure waveform parameters, etc.;

[0187] (3) a glucose sensor module 250, which is snap-fitted to the other end of the base 210, for example, by sliding in, and is used to sense CSF glucose parameters / signals in the pipeline of the external drainage-sensing assembly 200. The sensed glucose parameters / signals can be processed together with the continuous blood glucose monitoring measured at the patient end, for example, calculating their ratio, etc.;

[0188] (4) A spectral sensor 260, which in this embodiment is mounted on (e.g., embedded in) the base 210 and works in conjunction with a matching LED light source 140 operably mounted on the flip cover 120 of the external drainage monitoring device 100 to monitor the color / color change of the CSF in the pipeline.

[0189] Of course, those skilled in the art will appreciate that the spectral sensor 260 (together with the working light source 140) may also be designed as an independent integrated module operably associated / connected to the CSF drainage tube, just like the pressure sensor module 240 and the glucose sensor module 250. These are all within the scope of the present invention.

[0190] Although the above embodiment of the external drainage-sensing component 200 includes the pressure sensor module 240, the glucose sensor module 250 and the spectral sensor 260 as shown in the figure, a person of ordinary skill in the art should understand that, according to the predetermined configuration and application, design and customer requirements, etc., the external drainage-sensing component 200 may also include any one or any two of the pressure sensor module 240, the glucose sensor module 250 and the spectral sensor 260, and may also include more sensors or sensor modules of other types, as well as additional functional devices or modules, etc., which are all within the scope of the present invention.

[0191] Further Figures 3A-3C As shown, the pressure sensor module 240 is mounted on one end of the base 210 (eg Figure 3CThe connector 240C at one exposed end can be connected to the extracorporeal drainage catheter 220 at the ventricular end through the connector 220B to form a fluid connection, and the working part of the pressure sensor 2401 is exposed in the lumen formed by its tubular body (e.g., medical plastic parts, such as PVC, TPU, etc.) 240B to sense the CSF fluid pressure in the lumen, and its pressure sensor connection contact 240A is connected to the corresponding electrical contact (e.g., elastic / spring electrical contact) 213 on the base 210 to form an electrical connection, and the other end can be provided with a connector (e.g., a knob connector) 240D to connect with, for example, a glucose sensor module 250 to form a fluid connection, as described below.

[0192] The glucose sensor module 250 is mounted and fitted on the other end of the base 210 (eg Figure 3C The connector (e.g., knob connector) 250D at one exposed end can be connected to the collection end extracorporeal drainage catheter 230 through the connector 230B to form fluid communication, and the working part of the glucose sensor 2501 (e.g., Figure 3C The needle-shaped / tip portion shown in the figure extends into the lumen formed by its tubular body (e.g., a medical plastic part) 250B to sense the glucose signal / data in the CSF in the lumen, and its glucose sensor connection contact 250A is connected to the corresponding electrical contact (e.g., elastic / spring electrical contact) 214 on the base 210 to form an electrical connection, and its other end (the left end shown in the figure) may be provided with a connector 250C to connect with, for example, a pressure sensor module 240 to form a fluid connection, as described below.

[0193] As shown in this embodiment, the spectral sensor 260 can be directly embedded in the base 210 and work in conjunction with, for example, an LED light source 140 operably mounted on the flip cover 120 of the external drainage monitoring device 100 and electrically / signally connected thereto to monitor the color / color changes of the CSF in the pipeline.

[0194] The signal conditioning circuits of the pressure sensor module 240 and the glucose sensor module 250 (and the spectral sensor 260, if necessary) can be integrated on the base 210, and the base 210 can be provided with a bottom communication interface 210B for electrical connection with the host circuit (including the microprocessor 180) of the external drainage monitoring device 100. As a preferred example, the base 210 can be provided with a magnetic member 210A (such as a magnet in the form of a magnetic sheet, a magnetic coating, a magnetic block, etc.) at or near the bottom communication interface 210B, so that the base 210 is constructed as a magnetic base for magnetic connection to the external drainage monitoring device 100. Of course, it is also possible to choose to set a magnet at the corresponding position of the external drainage monitoring device 100 and provide an iron component / part near the bottom communication interface 210B, or to set a magnet on both, etc., all of which are within the scope of the present invention.

[0195] Pressure sensor module

[0196] Figure 4A It can be used as Figure 3A A schematic perspective view of a pressure sensor module 240 that is a portion of a drain-sense assembly 200 is shown. Figure 4B yes Figure 4A The schematic exploded view of the pressure sensor module 240 shown in FIG. 1 shows the details of its detailed structure and components. Figures 4A-4B As shown, the pressure sensor module 240 is an independent module integrated into a whole by various components, and includes a tubular body 240B made of, for example, medical plastic material, for example, by injection molding, with one end (for example, Figure 4B The left end shown in the figure) is provided with a plug-in connector 240C, for example, and is installed at the other end (for example Figure 4B The connector 240D (as shown on the right end) may be, for example, a knob connector that can be twisted to tighten and loosen, or the like.

[0197] The pressure sensor module 240 also includes a pressure sensor 2401, which is embedded in a corresponding mounting hole at a side (circumferential) position of the tubular body 240B and fixed by a pressure sensor mounting component 241, so that a working (sensing) portion on one side is exposed to the fluid in the lumen, such as CSF, for sensing; and a pressure sensor connecting contact 240A on the opposite side is exposed through an opening provided at a corresponding position of the pressure sensor mounting component 241, and is used to connect with a corresponding electrical contact (e.g., an elastic / spring electrical contact) 213 on the base 210 to form an electrical connection.

[0198] The pressure sensor mounting member 241 of the pressure sensor module 240 can be, for example, a snap-on fixing member in the form of a plastic plate of medical material integrally injection-molded as shown in the figure, which is used to mount and fix the pressure sensor 2401 on the tubular body 240B. Along the longitudinal center line of the pressure sensor mounting plate 241, a fin with a slot hole is provided on the left and right sides thereof, namely, a fin 242A with a slot hole 243A, and a fin 242B with a slot hole 243B. These two fins 242A and 242B are used to slide into and fit and be fixed to the base 210 of the external drainage-sensing assembly 200, as described in further detail below.

[0199] Base

[0200] Figure 5A It can be used as Figure 3A A schematic perspective view of the base 210 of the external drainage-sensing assembly 200 is shown, illustrating its exemplary overall construction and configuration. Figure 5B yes Figure 5AThe schematic three-dimensional view of the base 210 after being turned 180 degrees focuses on illustrating the structure and configuration of the base 210 .

[0201] like Figure 5A-5B As shown, the main body of the base 210 can be, for example, a plastic part, preferably a main body of a medical plastic material that is integrally injection molded. In this embodiment, the front side (i.e., the side that interfaces with each sensor) of the base 210 can be provided with mounting portions for mounting sensors (modules) at both ends, which can also be integrally injection molded with the main body of the base 210.

[0202] like Figure 5A As shown, at the right end of the base 210, a mounting portion is provided on the left and right sides along the longitudinal center line of the base 210, for example, a mounting portion in the form of a left and right fixing buckle 211A and 211B. The left and right fixing buckles 211A and 211B, for example, have a substantially inverted L-shaped cross section, and form a mounting guide groove with the front of the base 210, which is used to install the corresponding mounting features arranged on the sensor module (for example, the pressure sensor module 240, the fins on the glucose sensor module 250, etc.) in the mounting guide groove, for example, in a sliding manner. At least one of the left and right fixing buckles 211A and 211B (including both), for example, one of them, as shown in the figure, is the left fixing buckle 211B, and can further include a guide rib 211C that cooperates with it, and the guide rib 211C is arranged directly below the left fixing buckle 211B and is located on the front of the base 210 (for example, it can be integrally injection molded with the base 210). Furthermore, the guide rib 211C is preferably configured to have a wedge shape or a wedge-shaped introduction end as shown in the figure, so as to facilitate smooth introduction when the sensor module (e.g., its fin) is slid into the installation. Furthermore, the shape and size of the guide rib 211C are configured so that after the corresponding fin of the sensor module is installed and matched in place, the guide rib 211C is snapped into the slot of the corresponding fin (e.g., slot 243A, 243B, 253A, 253B, etc.), thereby firmly snapping and fixing the sensor module on the base 210 without slipping off. As described above, although not shown, both the left and right fixing buckles 211A and 211B can be provided with similar guide ribs.

[0203] Similarly, if Figure 5AAs shown, at the left end of the base 210, a mounting portion is provided on both sides of the left and right sides along the longitudinal center line of the base 210, such as a mounting portion in the form of a left and a right fixing buckle 212A and 212B. The left and right fixing buckles 212A and 212B, for example, have a substantially inverted L-shaped cross section, which forms a mounting guide groove with the front of the base, and is used to install the mounting features arranged correspondingly on the sensor module (for example, the pressure sensor module 240, the fins on the glucose sensor module 250, etc.) in the mounting guide groove, for example, in a sliding manner. At least one of the left and right fixing buckles 212A and 212B (including both), for example, one of them, as shown in the figure, is the left fixing buckle 212B, and can further include a guide rib 212C that cooperates with it, and the guide rib 212C is arranged directly below the left fixing buckle 212B and is located on the front of the base 210 (for example, it can be integrally injection molded with the base 210). Furthermore, the guide rib 212C is preferably configured to have a wedge shape or a wedge-shaped introduction end as shown in the figure, so as to facilitate the smooth introduction of the corresponding sensor module fin when the sensor module is slid into the installation, and the shape and size of the guide rib 212C are set so that the guide rib 212C is inserted into the slot (e.g., slot 243A, 243B, 253A, 253B, etc.) of the corresponding fin after the corresponding fin is installed and fitted in place, thereby firmly snapping and fixing the sensor module on the base 210 without slipping. As described above, although not shown, both the left and right fixing buckles 212A and 212B can be similarly provided with guide ribs.

[0204] like Figure 5A As shown, electrical contacts are provided at the left and right ends of the front side of the base 210 (i.e., the side that docks with each sensor), such as two electrical contacts 213 and 214 in the form of springs or elastic contacts as shown in the figure, which can be used to electrically connect to the pressure sensor connection contacts and the glucose sensor connection contacts, respectively.

[0205] In addition, a spectral sensor installation portion (installation opening) may be provided on the front side of the base 210 for installing the spectral sensor 260. Figure 5A In other words, the base 210 can be equipped with a self-contained spectral sensor 260 .

[0206] As a preferred example, Figure 5A As shown, a drainage tube buckle 215 may also be provided on the front side of the base 210 (eg, integrally injection molded with the base body, etc.) for fixing the drainage tube.

[0207] Figure 5BThe structure and configuration of the bottom of the base 210 are schematically shown. As shown in the figure, the base 210 may be provided with a bottom communication interface 210B for electrical / communication connection with the host circuit (including the microprocessor 180) of the external drainage monitoring device 100. As a preferred example, the base 210 may be provided with a magnetic attraction member 210A (such as a magnet in the form of a magnetic sheet, a magnetic coating, a magnetic block, etc.) at or near the bottom communication interface 210B, so that the base 210 is configured as a magnetic attraction base for magnetic attraction connection to the external drainage monitoring device 100.

[0208] Glucose sensor module

Figure 6B yes Fig. 6A A schematic exploded view of glucose sensor module 250 is shown, illustrating details of its detailed construction and component parts.

[0211] The glucose sensor module 250 also includes a glucose sensor 2501 with a needle-shaped or columnar sensing portion, which is integrated together with a contact connector 250F, for example, made of silicone material, and a contact adapter plate 250E having a glucose sensor connecting contact 250A thereon by means of a bracket 254, for example, in the form of a plastic part, and is, for example, embedded in a corresponding mounting hole of the tubular body 250B and fixed by a glucose sensor mounting component 251, so that the needle-shaped or columnar sensing portion on one side is exposed to the fluid in the lumen, such as CSF, for glucose sensing; and the glucose sensor connecting contact 250A on the other side is exposed through an opening provided at a corresponding position of the glucose sensor mounting component 251, and is used to dock with a corresponding electrical contact (for example, an elastic / spring electrical contact) 214 on the base 210 to form an electrical connection.

[0212] The glucose sensor mounting member 251 of the glucose sensor module 250 can be, for example, a snap-fit ​​fixing member in the form of a plastic plate of medical material integrally injection-molded as shown in the figure, and is used to mount and fix the glucose sensor 2501 on the tubular body 250B in the manner described above. Along the longitudinal center line of the glucose sensor mounting plate 251, a fin with a slotted hole is provided on each of its left and right sides, i.e., a fin 252A with a slotted hole 253A, and a fin 252B with a slotted hole 253B. These two fins 252A and 252B are used to slide into (or click-fit, snap-fit) on the base 210 of the external drainage-sensing assembly 200, as described in further detail below.

[0213] Spectral sensor components

[0214] The spectral sensor assembly can be a structure of an integral module such as an integral injection molding like the glucose sensor module or the pressure sensor module described above, or can be a component composed of a spectral sensor 260 and a working light source (such as LED 140) arranged separately, all of which are within the scope of the present invention. Figure 1A-5A As shown and as described above, the spectrum sensor assembly includes a spectrum sensor 260 disposed on the base 210, and an LED light source 140 disposed inside the flip cover 120 of the external drainage monitoring device 100. The installation position of the LED light source 140 corresponds to the position that provides an illumination light source for the spectrum sensor 260 to work normally when the flip cover 120 is closed.

[0229] Hydraulic-electric dual-use locking connector for intelligent external ventricular drainage system

[0230] External ventricular drains and lumbar drains (LDs) are one of the most common treatments for critically ill neurological patients. They refer to the placement of temporary drainage tubes in the lateral ventricles of the brain and the lumbar subarachnoid space to facilitate external drainage of cerebrospinal fluid (CSF) and monitoring of CSF pressure. In this case where both liquid drainage and built-in sensors in the cavity for monitoring are required, the usual practice is to use a three-way interface, electro-hydraulic separation and sealing, which requires the sensor to pass through the three-way and then through the drainage tube before it can be implanted in the preset position; this cumbersome operation greatly increases the duration of the operation, thereby increasing the patient's pain and the risk of surgery. Currently on the market, there is no quick connector that integrates two functions into one, which can achieve both liquid connection and circuit connection, and can achieve both catheter sealing and circuit waterproofing.

[0231] In order to solve the above drawbacks, a locking joint suitable for the medical field, especially for drainage pipe connection of external ventricular drainage and lumbar drainage, is provided, which can realize liquid-electric (fluid and electricity) connection through a single joint. By configuring specially designed mating joint ends at both ends of the joint connection, the above liquid-electric (fluid and electricity) connection purpose can be achieved through one operation, which not only meets the clinical medical needs, but also simplifies the operation steps, shortens the operation time, and in some cases can also reduce the patient's pain and surgical risks.

[0232] Fig. 8A It is available for Figure 1A A schematic three-dimensional view of an exemplary embodiment of a hydraulic-electric dual-purpose locking connector 400 that can be used in an intelligent external ventricular drainage system is shown, illustrating its overall structure. Figure 8B yes Fig. 8A The schematic exploded view of the hydraulic and electric dual-purpose locking connector 400 is shown, showing the details of its detailed structure and components. Figure 8C yes Fig. 8A The schematic cross-sectional view of the hydraulic and electric dual-purpose locking connector 400 along its longitudinal centerline further illustrates the details of its detailed construction and assembly.

[0233] like Figures 8A-8C As shown, the hydraulic-electric dual-purpose locking connector 400 generally includes: a locking nut 410 (for example, made of insulating material), a connector male end 420 for example with a foolproof design, a waterproof rubber ring 430 (for example, made of silicone material) and a connector female end 440 for example with a foolproof design, which can be assembled together to form a connector as shown in FIG. Fig. 8A The main body structure of the hydraulic and electrical dual-purpose locking connector 40 is shown.

[0234] Fig.8D yes Fig. 8A The schematic diagram of the connector male end 420 of the hydraulic-electric dual-purpose locking connector 400 shows its detailed structure and component details, especially the part connected to the connector female end 440. Fig. 8E yes Fig. 8A The schematic diagram of the connector male end 420 of the hydraulic-electric dual-purpose locking connector 400 shows its detailed structure and component details, especially the structure of the side connected to the external hydraulic and electrical connection.

[0235] like Figures 8A-8E As shown, one side of the connector male end 420 ( Fig.8DThe male end 420 of the connector is provided with a generally cylindrical male end inlet body 421, for example, made of an insulating material (e.g., PE), a Luer connector concave end 422 disposed on the end face of the male end inlet body 421, and at least one electrode contact recess 423 disposed on the same end face of the male end inlet body 421, which is made of, for example, a conductive metal such as copper and may be coated with gold. This side of the male end 420 of the connector is also provided with a foolproof structure ( Fig.8D Shown as a radially inwardly concave groove) 4211.

[0236] On the other side of the male end 420 of the connector ( Fig. 8E As shown on the left side, a male end external body 424 of a tapered shape, such as a truncated cone shape (for example, shown as being on its end surface outer end surface 4241) is provided with: a fluid path interface 4212 in the form of a protruding pipeline connected to the female end 422 of the Luer connector, for example, for connecting to a fluid flow channel such as a drainage tube to form a fluid connection, which can be provided in a substantially central position as shown in the figure; and a circuit interface 4213 in the form of, for example, an electrode or a pipeline (of course, it can also be in other available forms, such as a solid wire with an outer insulation layer, etc.). In addition, in the example shown as A circle of flange 425 in the form of an outward flange is formed between the frustoconical male end external body 424 and the substantially cylindrical male end internal body 421, and a plurality of radially outwardly protruding locking nut anti-slip structures 4214 are designed along the circumferential direction of the flange 425. An example thereof is a (for example, substantially L-shaped) boss 4214, and an axial gap 4215 is formed between the boss 4214 and the flange 425 for accommodating the inward flange 411 at one end of the locking nut 410, which is used to prevent the locking nut 410 from falling off and to tighten it when it is screwed on.

[0237] Figure 8F yes Fig. 8A The schematic diagram of the female connector 440 of the hydraulic and electrical dual-purpose locking connector 400 shows its detailed structure and component details, especially the part connected to the male connector 420. As shown in the figure, the female connector 440 is Figure 8F On the outer end surface 4415 of the tapered, for example, truncated cone-shaped female end external body 441 at the right end shown (i.e., the end where the liquid-electric interface is exposed after assembly), there are provided: a liquid circuit interface 4414, for example, in the form of a protruding pipeline, which is configured to communicate with the hollow Luer connector protrusion 442442, and is used to connect with a liquid flow channel such as a drainage tube to form fluid communication, which can be arranged in a substantially central position as shown in the figure and is in liquid communication with the liquid circuit interface 4212 after assembly; and a circuit interface 4413, for example, preferably in the form of an electrode or a pipeline (of course, it can also be other available forms, such as a solid wire with an outer insulation layer, etc.), which is also in electrical communication with the circuit interface 4213 after assembly. The female end 440 of the connector is Figure 8F The left end shown, i.e., the end that is butted with the male end 420 of the connector, is formed with a female end inscribed body 444 that is substantially in the form of a hollow cylinder. At the bottom end of the cylindrical female end inscribed body 444, an axially extending hollow Luer connector male end 442 is provided for butting with the Luer connector female end 422 of the male end 420 of the connector. In this regard, as a non-limiting example, the Luer connector female end 422 may be an inner cone interface, and the Luer connector male end 442 may be an outer cone interface, and the inner and outer cones may meet the requirements of the GB / T1962.1-2005 standard. In this way, after the male end 420 of the connector is connected to the female end 440 of the connector, the two cone surfaces are in contact, and pressure is applied on both sides in the direction of approaching each other to press the cone mouth tightly, so that the pipeline is sealed to prevent leakage of liquid in the pipeline. Furthermore, at the bottom end of the female end internal body 444, at least one (as shown in the figure, multiple) electrode contact protrusion needle 443 is provided for docking with the electrode contact recess 423 of the male end 420 of the connector. In addition, on the outer periphery of the female end internal body 444 of the connector female end 440, for example, an external threaded portion 4412 is provided for mating with the internal thread 412 of the locking nut 410, and an anti-fool structure 4411 is also provided on the inner peripheral wall of the hollow inner cavity of the hollow cylindrical female end internal body 444, which is, for example, a ridge 4411 protruding radially inwardly from the inner peripheral wall for mating with the internal thread 412 of the locking nut 410. Fig.8D The outer thread portion 4412 can be a multi-threaded portion, which can reduce the number of turns required for tightening and increase the locking effect.

[0238] Figure 8C The cross-sectional view along the longitudinal axis of the further shows the detailed structure and details of the assembled hydraulic and electrical dual-purpose locking connector 400. Figure 8C As shown, during assembly, the waterproof rubber ring 430 is clamped between the male end 420 of the connector and the female end 440 of the connector, and the male end 420 of the connector is connected to the female end 440 of the connector, so that the Luer connector protrusion 442 of the female end 440 of the connector is inserted into the Luer connector concave end 422 of the male end 420 of the connector to form a liquid fluid connection of the liquid path, and the electrode contact protrusion 443 of the female end 440 of the connector is inserted into the electrode contact recess 423 of the male end 420 of the connector to form an electrical connection.

[0239] As shown in the figure, the inward flange of the locking nut 430 on the side of the male end 420 of the connector is stuck in the axial interval formed between the boss 4214 that prevents the locking nut from loosening and the flange, and on the side of the female end 440 of the connector, the nut is screwed on the external threaded portion 4412 of the female end 440 of the connector. By screwing and tightening, the waterproof rubber ring 430 can be clamped and pressed between the male end 420 of the connector and the female end 440 of the connector in the axial direction, thereby tightly fitting and connecting the Luer connector male end 442 and the Luer connector female end 422, and tightly fitting and connecting the electrode contact convex needle 443 and the electrode contact recess 423. In addition, due to the pressing pressure during screwing and tightening, the (electrically insulating) butt end faces of the male end 420 of the connector and the female end 440 of the connector are pressed together, thereby achieving a liquid-tight connection and an electrically insulating sealed connection. In addition, the insulating (e.g. silicone) waterproof rubber ring 430 tightly clamped between the two is tightly crimped to the male end 420 of the connector on one side, and the other side is pressed against the end face of the opening side of the hollow cylinder of the female end connected to the main body 444 of the female end 440 of the connector in a watertight manner due to the pressing pressure when the locking nut 410 is tightened, thereby completely sealing the hollow cylinder from the outside of the hydraulic and electrical dual-purpose locking connector 400.

[0240] Since the tight-fitting connection interface between the Luer connector convex end 442 and the Luer connector concave end 422, and the tight-fitting connection interface between the electrode contact convex needle 443 and the electrode contact concave seat 423, are all located in the hollow cylinder 444 that is completely isolated and sealed from the outside, in fact, the hydraulic-electric dual-purpose locking connector 400 can not only achieve the connection between the circuit and the liquid circuit inside, but also achieve the effect of sealing and isolating the internal circuit and liquid circuit connection parts from the outside. Not only that, as shown in the figure, as described above, since the electrically insulated butt end faces of the connector male end 420 and the connector female end 440 are pressed and abutted together, the water circuit and liquid circuit connection parts are also completely isolated and insulated from each other inside the hydraulic-electric dual-purpose locking connector 400, ensuring that there is no liquid leakage inside, and there will be no situation where liquid leakage causes internal circuit short circuit.

[0241] As described above, the dual-purpose hydraulic-electrical locking connector 400 can be used for the connection of one or both of the circuit connection and the liquid circuit connection in the medical field, especially the dual-purpose hydraulic-electrical connection, which can realize the rapid connection of the liquid circuit and the circuit with a single connector and a single connection, and at the same time meet the requirements of the liquid circuit liquid-tight sealing and the circuit leakage prevention at the connector. In addition, the connector can realize the rapid connection and disconnection of the connector through simple actions, and can realize the reliability and stability of the connector connection through the built-in locking nut, and further enhance the performance of anti-leakage and anti-leakage.

[0242] The hydraulic-electric dual-purpose locking connector of the utility model can not only be used for connecting the pipelines (such as external drainage pipelines) of the intelligent external ventricular drainage system, but also can be used in other applications in the medical field, such as but not limited to the connection of drainage pipelines for lumbar drainage, etc., and provide the technical effects as described above.

[0247] Then, the external drainage-sensing assembly 200 connected to the patient-side drainage line 300 is connected to an extracorporeal collection device such as 600 through a connector;
