Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adaptive drainage regulating device. Background Art

[0002] Neurosurgery is a common method for treating craniocerebral trauma, cerebrospinal effusion, hypertensive cerebral hemorrhage and other diseases. Due to the deep surgical site and the wide range of surgical wounds, it is often necessary to place a drainage tube to continuously drain cerebrospinal fluid after surgery to promote the growth of the surgical wound, reduce cerebrospinal fluid leakage, prevent increased intracranial pressure, and avoid secondary intracranial infection. The effect of catheter drainage directly affects the patient's postoperative recovery. The care of ventricular catheter drainage is particularly important. Among them, the adjustment of the height of the drainage tube will directly affect the change of intracranial pressure. If the drainage bag is too high, it may lead to poor drainage, and if it is too low, it will lead to excessive drainage and cause intracranial hypotension syndrome.

The support plate 100 is used to be connected to a fixed structure; the fluid accumulation component 200 is movably connected to the support plate 100; one end of the drainage pipeline 300 is connected to the fluid accumulation component 200, and the other end is used to be connected to the drainage part; the detection component 400 is connected to the drainage pipeline 300, and is used to detect the pressure of the drainage part and the external atmosphere; the detection component 400 is communicatively connected to the control unit 500; the transmission component 600 is connected to the support plate 100 and the fluid accumulation component 200 to drive the fluid accumulation component 200 to move relative to the support plate 100 to adjust the height of the fluid accumulation component 200; wherein the control unit 500 can control the operation of the transmission component 600 according to the detection result of the detection component 400.

[0044] The present technical solution provides an adaptive drainage adjustment device, in which the support plate 100 is used to be connected to a fixed structure so as to support the fluid accumulation component 200, the drainage pipeline 300, the transmission component 600, etc. on the fixed structure.

The drainage pipeline 300 is used to achieve the connection between the fluid accumulation component 200 and the drainage part, so that the drainage fluid can flow from the drainage part into the fluid accumulation component 200. By arranging a detection part 400 on the drainage pipeline 300, the pressure of the drainage part and the pressure of the external atmospheric pressure can be checked.

Through the above structure, the adaptive drainage adjustment device can adaptively adjust the height of the effusion assembly 200 according to the pressure difference between the drainage part and the external atmospheric pressure, thereby improving the drainage effect.

[0045] It is understandable that the specific structure of the fixed structure is not limited, and it can be a wall, a bracket on a hospital bed, etc. There is no limitation on the connection method between the support plate 100 and the fixed structure, and the support plate 100 includes a plate body 110. In one embodiment, a mounting hole 111 is provided on the plate body 110, and the mounting hole 111 is used to be hooked and connected with a hook on the fixed structure. Such a configuration makes the connection convenient and easy to disassemble and move. Of course, in other embodiments, a fastener 112 can also be provided on the plate body 110, and the fastener 112 is used to be threadedly fixedly connected with a threaded hole on the fixed structure. Such a connection has the advantage of stable and reliable connection.

[0046] like Figure 1 As shown, in one embodiment, the support plate 100 includes a plate body 110 and a guide rail 120, the plate body 110 is used to be connected to a fixed structure; the guide rail 120 is fixedly connected to the plate body 110, and the part of the transmission assembly 600 connected to the fluid accumulation assembly 200 is guided and cooperated with the guide rail 120.

[0047] By matching the portion where the transmission assembly 600 is connected to the fluid accumulation assembly 200 with the guide rail 120, the moving portion of the transmission assembly 600 is guided, so that the movement of the fluid accumulation assembly 200 relative to the plate body 110 is made more reliable and stable. There is no limitation on the structure of the guide rail 120, and a guide groove may be provided on a plate body, and the portion where the transmission assembly 600 is connected to the fluid accumulation assembly 200 may be slid into the guide groove. In another embodiment, the guide groove may be directly provided on the plate body 110. In the present embodiment, a scale line is provided on one side of the guide rail 120 on the plate body 110 to facilitate quantitative adjustment of the height of the fluid accumulation assembly 200.

[0048] like Figure 1 As shown, in one embodiment, the transmission assembly 600 includes a driving member 610 and a slider 620, the driving member 610 is fixedly connected to the plate body 110; the slider 620 is connected to the driving end of the driving member 610, the slider 620 is fixedly connected to the fluid accumulation assembly 200, and cooperates with the guide rail 120 for guidance.

[0049] Specifically, the driving member 610 may be a driving motor, a piston rod, a cylinder, etc. The driving end of the driving member 610 is connected to the slider 620, so that the slider 620 is driven by the driving end of the driving member 610 to move relative to the plate body 110, thereby adjusting the height of the effusion assembly 200. The slider 620 is guided by the guide rail 120 to guide the movement of the slider 620.

[0050] like Figure 1 As shown, in one embodiment, the transmission assembly 600 further includes a transmission rod 630, the transmission rod 630 is rotatably connected to the plate body 110, the transmission rod 630 is fixedly connected to the driving end of the driving member 610, and the slider 620 is threadedly connected to the transmission rod 630. In this embodiment, the driving member 610 is a driving motor, the output shaft of the driving motor is fixedly connected to the transmission rod 630, the transmission rod 630 is rotatably connected to the plate body 110 through a bearing, the transmission rod 630 is provided with an external thread, the transmission rod 630 is threadedly connected to the slider 620, when the transmission rod 630 rotates relative to the plate body 110 driven by the driving motor, the slider 620 can only move linearly along the guide rail 120 under the limit of the guide rail 120, thereby driving the effusion assembly 200 to move relative to the plate body 110. The above structure has the advantages of simple and compact structure, stable and reliable adjustment.

[0051] like Figure 1As shown, in one embodiment, the detection member 400 includes a first pressure sensor 410 and a second pressure sensor 420. The first pressure sensor 410 is disposed in the drainage pipeline 300 and is connected to the control unit 500 for communication. The first pressure sensor 410 is used to detect the pressure of the drainage part; the second pressure sensor 420 is disposed outside the drainage pipeline 300 and is connected to the control unit 500 for communication. The second pressure sensor 420 is used to detect the pressure of the external atmospheric pressure. The driving member 610 is connected to the control unit 500 for communication. The control unit 500 controls the driving member 610 to operate according to the detection results of the first pressure sensor 410 and the second pressure sensor 420, so that the driving end of the driving member 610 drives the slider 620 to move along the guide rail 120.

[0052] Such arrangement enables the control unit 500 to calculate the pressure difference between the drainage site and the external atmospheric pressure based on the detection results of the first pressure sensor 410 and the second pressure sensor 420. When the pressure difference exceeds a preset range, the control unit 500 controls the fluid accumulation component 200 to move upward so as to increase the height of the fluid accumulation component 200, thereby facilitating drainage.

[0053] like Figure 1 As shown, in one embodiment, the adaptive drainage regulating device also includes a flow detection member 700, which is arranged on the drainage pipeline 300 and is in communication connection with the control unit 500. The control unit 500 can control the flow rate in the drainage pipeline 300 according to the detection result of the flow detection member 700. By arranging the flow detection member 700 on the drainage pipeline 300, the control unit 500 can control the flow rate in the drainage pipeline 300 through the flow of the flow detection member 700, so as to accurately control the drainage rate and improve the drainage effect. Specifically, the flow detection member is a flow sensor. The flow result in the drainage pipeline detected by the flow sensor can be used to control the driving member through the control unit to adjust the height of the effusion bottle, thereby controlling the drainage rate through the siphon effect.

[0054] like Figure 1 As shown, in one embodiment, the fluid collection component 200 includes a fluid collection bottle 210, a three-way valve 220 and a drainage bag 230. The fluid collection bottle 210 is connected to the drainage pipeline 300, and the transmission component 600 is fixedly connected to the fluid collection bottle 210; one passage of the three-way valve 220 is connected to the fluid collection bottle 210, and one passage is used for sampling; the drainage bag 230 is connected to another passage of the three-way valve 220. The fluid collection component 200 also includes a two-way valve 240, and one passage of the two-way valve 240 is connected to the drainage bag 230.

[0055] The fluid collection bottle 210 is connected to the drainage bag 230 through a three-way valve, so that the drainage fluid in the fluid collection bottle 210 flows into the drainage bag 230, and the drainage fluid can be extracted for analysis through another passage of the three-way valve 220. A two-way valve 240 is provided at one end of the drainage bag 230 away from the fluid collection bottle 210, so that the drainage fluid in the drainage bag 230 can be discharged at any time through the two-way valve 240.

[0056] Reference Figure 1 It is understood that the working principle of the adaptive drainage adjustment device provided in the embodiment of the utility model is as follows:

[0057] By placing a first pressure sensor 410 in the drainage line 300 of the adaptive drainage regulating device, and arranging a second pressure sensor 420 outside the drainage line 300, the first pressure sensor 410 placed in the drainage line 300 is used to monitor the pressure of the patient's drainage site, for example, intracranial pressure; the second pressure sensor 420 placed outside the drainage line 300 is used to monitor the atmospheric pressure. The first pressure sensor 410 and the second pressure sensor 420 transmit the patient's intracranial and extracranial pressure difference data to the control unit 500 through the pressure sensor data interface, and the control unit 500 calculates the patient's actual intracranial pressure data according to the difference between the two data. The upper end of the effusion bottle 210 is connected to the drainage line 300, and the lower end is connected to the drainage bag 230 through the three-way valve 220. The three-way valve 220 is used to control the discharge of the liquid in the effusion bottle 210 to the drainage bag 230, and facilitates the suction and detection of the drainage fluid. The two-way valve is connected to the lower end of the drainage bag 230 to control the discharge of the liquid in the drainage bag 230. The upper end of the plate body 110 is provided with a mounting hole 111, which is also a hanging hole, for convenient hanging. The mounting and fixing can be achieved by a fastener 112, for example, a locking screw. The guide rail 120 is installed in the central groove of the plate body 110, the output shaft of the driving motor is fixedly connected to the transmission rod 630, the transmission rod 630 is threadedly connected to the slider 620, the slider 620 is guided and matched with the guide rail 120, and the effusion bottle 210 is installed on the slider 620. The driving motor drives the transmission rod 630 to rotate, and then drives the slider 620 to move along the guide rail 120, so as to adjust the height of the effusion bottle 210. In this way, the height difference of the drainage liquid level position in the effusion bottle 210 relative to the outlet position of the drainage pipeline 300 is controlled, and the control unit 500 adaptively adjusts the adjustment height of the slider 620 according to the real-time intracranial pressure changes collected, and then relies on the siphon effect to control the drainage speed of the device.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
