DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0032] Existing ventricular drainage tube fixing devices are difficult to monitor the patient's ventricular pressure and drainage volume in real time, and often require manual detection. Drainage problems cannot be discovered and adjusted in time, affecting the treatment effect.

[0033] Please refer to Figure 1 This embodiment provides a sensor-based ventricular drainage tube fixing and flow limiting device, which is connected with the drainage tube 21, and includes:

[0034] A main body 100, a pressure display 110, a flow display 210, a pressure sensor 120, a first flow sensor 221, a second flow sensor 222 and a flow limiting member 300;

[0035] The pressure display 110 and the flow display 210 are both arranged on the main body 100; the main body 100 has a connecting channel 101 penetrating therethrough, and the drainage tube 21 is arranged in the connecting channel 101;

[0036] The two ends of the connecting channel form a first opening 101a and a second opening 101b on the main body 100 respectively; in the connecting channel 101, the direction from the first opening 101a to the second opening 101b is the same as the flow direction of the liquid in the drainage tube 21;

[0037] The first flow sensor 221 is disposed on the drainage tube 21 near the first opening 101a, and the second flow sensor 222 is disposed on the drainage tube 21 near the second opening 101b; the first flow sensor 221 and the second flow sensor 222 are both connected to the flow display 210 to respectively display the flow at both ends of the drainage tube 21;

[0038] The pressure sensor 120 is configured to be connected to a patient to monitor the pressure of the patient's cerebral ventricle, and the pressure display 110 is electrically connected to the pressure sensor 120 to display the cerebral ventricle pressure;

[0039] The main body 100 is provided with a matching hole 102 communicating with the connecting channel 101 , and the flow limiting member 300 can be movably disposed in the matching hole 102 to squeeze the drainage tube 21 in the connecting channel 101 to reduce the flow in the drainage tube 21 .

[0040] It should be noted that the first flow sensor 221 and the second flow sensor 222 are used to display the flow at both ends of the drainage tube 21 on the flow display 210; the pressure display 110 is electrically connected to the pressure sensor 120 to display the ventricular pressure, so that the current patient's brain pressure and drainage volume can be understood through the display, so that medical staff can adjust the drainage flow in time to ensure the treatment effect. Compared with the method of measuring the ventricular pressure and drainage volume separately in the prior art and then adjusting the drainage tube 21, this solution has the advantages of data visualization, convenient operation and high integration. At the same time, after adjusting the flow limiter 300 so that the drainage volume of the drainage tube 21 meets the preset requirements, the adjusted ventricular pressure and flow data can also be seen in time on the two displays, thereby achieving the effect of timely feedback. Further, the pressure sensor 120, the first flow sensor 221, and the second flow sensor 222 can also be connected to the monitoring system to realize real-time remote monitoring and adjustment of the ventricular pressure and drainage volume, and improve the accuracy and safety of drainage.

[0041] from Figure 1 As can be seen in the figure, the connecting channel 101 and the matching hole 102 are both straight through holes extending in a straight direction. Optionally, the main body 100 is rectangular, and a connecting channel 101 is provided through the center of the main body 100, and the connecting channel 101 is a circular channel. The matching hole 102 is also a cylindrical through hole. A plurality of strapping bands 22 are detachably arranged on the main body 100 to fix the main body 100, thereby ensuring the stability of the sensor-based ventricular drainage tube fixing and limiting device.

[0042] The pressure sensor 120, the first flow sensor 221, and the second flow sensor 222 can be provided separately, or can be directly connected to the monitoring system by wire or wirelessly, so as to facilitate the integration of data transmission. Optionally, the pressure sensor 120 can directly collect the ventricular pressure of the monitoring system.

[0043] In an optional embodiment, the extending direction of the connecting channel 101 is at an angle to the extending direction of the matching hole 102. Specifically, in this embodiment, the extending direction of the connecting channel 101 is perpendicular to the extending direction of the matching hole 102. This approach can shorten the stroke of the flow limiting member 300, thereby improving the sensitivity and speed of flow regulation.

[0044] In an optional embodiment, the flow limiting member 300 is threadedly connected to the matching hole 102 so that the flow limiting member 300 is close to the connecting channel 101 or away from the connecting channel 101. Specifically, the cylindrical flow limiting member 300 is provided with an external thread, and the inner wall of the matching hole 102 is provided with an internal thread. The external thread of the flow limiting member 300 cooperates with the internal thread of the matching hole 102 to achieve the flow limiting member 300 close to or away from the drainage tube 21 in the connecting channel 101.

[0045] Optionally, a stroke sensor 400 is provided on the inner wall of the matching hole 102; the stroke sensor 400 is matched with the flow limiting member 300 so that the stroke sensor 400 can monitor the depth of the flow limiting member 300 penetrating into the connecting channel 101. The stroke sensor 400 can monitor the displacement of the flow limiting member 300 and feed back to the display, so that the medical staff can determine the flow limiting degree of the flow limiting member 300 according to the stroke change.

[0046] To ensure the integrity of the drainage tube 21 , in an optional embodiment, the flow limiting member 300 has a rounded head 310 at one end facing the connecting channel 101 .

[0047] from Figure 1 It can also be seen that in an optional embodiment, the sensor-based ventricular drainage tube fixing flow limiting device also includes a supporting mechanism 500, which is arranged on the inner wall of the connecting channel 101 away from the matching hole 102; the supporting mechanism 500 is used to support the drainage tube 21 to ensure that the flow limiting member 300 can squeeze the drainage tube 21 toward the supporting mechanism 500. This supporting mechanism 500 mainly ensures that when the flow limiting member 300 squeezes the drainage tube 21, the drainage tube 21 as a whole will not shake, so as to ensure the stability of adjusting the drainage amount. Optionally, the material of the supporting mechanism 500 is rubber. Because rubber has a large friction coefficient, the drainage tube 21 can be tightly attached to the supporting mechanism 500, thereby avoiding the shaking of the drainage tube 21.

[0048] In an optional embodiment, the sensor-based ventricular drainage tube fixing and flow limiting device further includes a buffer mechanism 600, which is disposed on the inner wall of the connecting channel 101 near the matching hole 102; the buffer mechanism 600 is directly opposite to the abutting mechanism 500 to define an accommodation space for the drainage tube 21 to pass through; and the buffer mechanism 600 provides elastic force so that the drainage tube 21 can be clamped between the buffer mechanism 600 and the abutting mechanism 500. Because the buffer mechanism 600 is elastic, it is convenient for the drainage tube 21 to pass through the connecting channel 101, and at the same time it can ensure that the drainage tube 21 will not slide randomly in the connecting channel 101, and can also ensure the stable connection between the drainage tube 21 and the main body 100 through the clamping force between the buffer mechanism 600 and the abutting mechanism 500. Optionally, the material of the buffer mechanism 600 is sponge.

[0049] It can also be seen from the figure that the buffer mechanism 600 is provided with a hole 610 for the matching hole 102 to pass through. The buffer mechanism 600 and the abutting mechanism 500 are both fixedly arranged on the inner wall of the connecting channel 101.

[0050] In summary, the embodiment of the utility model provides a sensor-based ventricular drainage tube fixed flow limiting device, which has the following advantages:

[0051] Such a sensor-based ventricular drainage tube 21 fixing device and drainage volume limiting device can monitor the patient's ventricular pressure and drainage volume in real time. By connecting to the monitoring system, real-time remote monitoring and adjustment of ventricular pressure and drainage volume can be achieved, thereby improving the accuracy and safety of drainage.

[0052] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
