Description

Technical Field

[0001] The utility model belongs to the technical field of medical supplies, and in particular relates to a flow monitoring device for a drainage tube. Background Art

[0002] Postoperative neurosurgery patients often have drainage tubes. Drainage care for ventricular and lumbar drainage tubes is particularly important, requiring accurate hourly drainage volume. Clinically, manual bedside monitoring of drainage volume is often used, which is labor-intensive and unable to effectively control the flow rate or monitor hourly drainage volume. Excessive cerebrospinal fluid drainage may lead to a series of serious complications, including headaches, altered consciousness, cranial nerve palsy, and possible brain herniation. This condition is usually associated with the rapid release of cerebrospinal fluid, which results in a pressure gradient within the cranial and spinal canal cavities, causing brain contents to shift toward the spinal canal, leading to traction and compression of cranial nerves and brain tissue, which is life-threatening.

[0003] Currently, a clamp-type infrared flow monitoring device is generally used to monitor cerebrospinal fluid flow rate. However, this type of monitoring device has the following problems: when the clamping part of the clamp-type infrared flow monitoring device is in a clamped state, if medical staff or the patient's family members accidentally apply external force to the clamping part, the clamping part will open, causing the monitoring device to detach or shift from the drainage tube, thereby affecting the monitoring effect. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a flow monitoring device for a drainage tube, which can maintain the clamping body in a closed state through a limit rod.

It can be said that the limit plate 21 is sleeved and fixed on the circumference of the limit rod 2 or is integrally formed on the circumference of the limit rod 2. The position of the limit plate 21 corresponds to the distance between the first movable end 111 and the second movable end 121 when the clamping body 1 is in the closed state; in this embodiment, the end of the limit rod 2 is connected to the rotating shaft 6 and is set at an angle to the clamping body 1, and rotates with the rotating shaft 6 as the rotation center, and the above-mentioned elastic card groove 112 is formed on one side in the longitudinal direction of the first movable end 111. The opening of the elastic card groove 112 is a narrow design.

[0037] In an optional embodiment, if Figure 2As shown, the first clamping arm 11 has a first arcuate groove 113, and the second clamping arm 12 has a second arcuate groove 123. The first arcuate groove 113 and the second arcuate groove 123 enclose the clamping cavity 13, and the wall of the clamping cavity 13 is closely arranged with the drainage tube. Specifically, the first arcuate groove 113 and the second arcuate groove 123 are designed as semicircular shapes, so that the shape of the clamping cavity 13 conforms to the drainage tube. Furthermore, the groove walls of the first arcuate groove 113 and the second arcuate groove 123 can be provided with anti-slip grooves to improve the clamping stability of the flow monitoring device and prevent the device from loosening.

After the first clamping arm 11 and the second clamping arm 12 are aligned through the connecting portion, the axle pin 15 is used to connect the first clamping arm 11, the second clamping arm 12 and the torsion spring 14. After the torsion spring 14 is partially sleeved on the axle pin 15, one end thereof abuts against the surface of the first movable end 111, and the other end abuts against the surface of the second movable end 121. By utilizing the performance of the torsion spring 14, after the external force applied to the first movable end 111 and the second movable end 121 is removed, the clamping body 1 can automatically restore from the open state to the closed state.

[0039] In an optional embodiment, the alarm 5 is an audible and visual alarm device for emitting an alarm and flashing lights. By emitting sound and flashing lights, medical staff can promptly detect abnormalities, quickly obtain alarm information, and promptly come to the patient to take countermeasures. Medical staff can turn off the alarm sound and flashing lights through the controller 3.

[0040] During use, after clamping the clamping body 1 and the drainage tube, rotate the limit rod 2 so that one end of the limit rod 2 is limitedly connected to the elastic slot 112 of the first movable end 111 or the fixed column 7, so that the clamping body 1 maintains a closed state. When it is necessary to adjust the position of the clamping body 1 on the drainage tube, the limit rod 2 is separated from the restriction of the elastic slot 112 or the fixed column 7, and the limit rod 2 is rotated in the opposite direction to release the restriction of the limit rod 2 on the clamping body 1. Medical staff can apply external force to the first movable end 111 and the second movable end 121 to bring the two together, thereby realizing the transition of the clamping body 1 from a closed state to an open state.

[0041] To sum up, after one end of the limit rod 2 is connected to the first movable end 111, the first movable end 111 and the second movable end 121 cannot approach each other, so as to realize the change of the state of limiting the clamping body 1, avoid accidental touch causing the flow monitoring device to loosen from the drainage tube, improve the connection stability of the flow monitoring device, and improve the accuracy of the device monitoring data; monitor the drainage flow rate every hour, and have an alarm function. When the flow rate of the drainage fluid is too fast, too slow or does not flow, an alarm sound and flash light are issued to remind medical staff; there is no need for manual monitoring by neurosurgery medical staff, and automatic monitoring reduces the labor intensity of neurosurgery medical staff and improves work efficiency.
