Abstract

The present invention discloses a real-time ultrasound detection drainage catheter, comprising: a drainage tube, the drainage tube comprising an insertion section inserted into the patient's brain and a reserved section reserved outside the patient's brain; a drainage port, the drainage port being opened at the head of the insertion section; an ultrasound detection module, the ultrasound detection module being inserted into the drainage tube and used to detect the position of the drainage tube in the patient's brain. After entering the brain tissue, the present invention can provide great accuracy for cranial puncture by detecting the situation and position direction in front in real time through ultrasound. Moreover, when entering the brain tissue, the drainage port can be blocked first to avoid a large amount of cerebrospinal fluid being drained, which causes changes in intracranial pressure and structural deviation, and can also protect the ultrasound probe from contamination.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a real-time ultrasound detection drainage catheter. Background Art

[0002] Cranial puncture uses CT and MRI techniques to observe the ventricles of healthy subjects and patients. Punctures in the frontal corner should be directed toward the midpoint of the line connecting the two external auditory canals, and punctures in the occipital corner should be directed between the inner end of the ipsilateral eyebrow arch and the midline. Continuous cerebrospinal fluid drainage through the lateral ventricle is valuable for improving the prognosis of patients with severe brainstem hemorrhage. Brainstem hemorrhage should be diagnosed and treated early. Severe brainstem hemorrhage should be diagnosed and treated as early as possible during the acute phase (≤72 hours), with lateral ventricle puncture and continuous cerebrospinal fluid drainage. Surgery should be performed as soon as possible before fatal complications, especially brain herniation, occur. Active comprehensive medical treatment measures, including dehydration to reduce intracranial pressure, cooling, prevention and treatment of stress-induced peptic ulcers and bleeding, anti-infection, and, if necessary, early tracheotomy and ventilator-assisted / controlled breathing, are the basis for successful rescue and treatment.

[0003] Currently, when performing deep and long-distance puncture in the brain, slight angle deviations are prone to occur, resulting in off-target phenomena, affecting the puncture effect. In addition, when performing deep and long-distance puncture in the brain, it is impossible to judge the angle direction in real time, which greatly reduces the accuracy of the puncture. Therefore, a real-time ultrasound detection drainage catheter is designed. Summary of the Invention

[0027] Figure 22 is a schematic diagram of the main cross-sectional structure of a drainage catheter in a puncture state for real-time ultrasound detection according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0029] First, combine Figures 1 and 2 A real-time ultrasound detection drainage catheter according to an embodiment of the present invention is described, which is used for deep and long-distance puncture of the brain and has a wide range of application scenarios.

[0030] like Figures 1 and 2 As shown, the real-time ultrasound detection drainage catheter according to an embodiment of the present invention comprises a drainage tube, a drainage port 2 and an ultrasound detection module.

[0031] Specifically, if Figures 1 and 2 As shown, in this embodiment, the drainage tube includes an insertion section 11 inserted into the patient's brain and a reserved section 12 reserved outside the patient's brain. The drainage port 2 is opened at the head of the insertion section 11, and the drainage port 2 is used for drainage. The ultrasonic detection module is inserted into the drainage tube to detect the position of the drainage tube in the patient's brain, so that the angular direction position of the insertion section 11 of the drainage tube can be accurately positioned in real time to prevent puncture deviation and ensure the accuracy of puncture.

[0032] Further, if Figures 1 and 2 As shown, in this embodiment, the ultrasound detection module includes an ultrasound detection component and a conduction protection component. The ultrasound detection component is placed in the drainage tube to detect the position of the drainage tube in the patient's brain. The conduction protection component is connected to the ultrasound detection component and is located between the ultrasound detection component and the drainage tube to conduct ultrasound and protect the ultrasound detection component from contamination.

[0033] Further, if Figures 1 and 2 As shown, in this embodiment, the ultrasonic detection assembly includes: an ultrasonic detection probe 311, a cable 312, and a connector 313. The ultrasonic detection probe 311 is disposed inside the insertion section 11 and is used to emit ultrasonic waves. One end of the cable 312 is connected to the ultrasonic detection probe 311, and the other end of the cable 312 is connected to the conductive protection assembly. The cable 312 is used to transmit data. One end of the connector 313 is connected to the other end of the cable 312, and the other end of the connector 313 is connected to an external host, and is used to send data detected by the ultrasonic detection probe 311 to the host for display by the host.

[0034] Further, if Figures 1 and 2As shown, in this embodiment, the conductive protection assembly includes a balloon and a filling port 322. The balloon has a contracted state and a filled state. The balloon is mounted on the ultrasonic detection assembly and positioned between the drainage tube and the ultrasonic detection assembly. The filling port 322 is located at the tail end of the balloon. During use, the balloon can be filled by injecting physiological saline through the filling port 322, which allows the balloon to conform to the inner wall of the insertion section 11 of the drainage tube and act as a coupling agent for the probe.

[0035] Further, if Figures 1 and 2 As shown, in this embodiment, the balloon includes a balloon head 3211 and a delivery tube 3212. The balloon head 3211 has a contracted state and a filled state. The balloon head 3211 is mounted on the ultrasonic detection probe 311 of the ultrasonic detection assembly and is located between the drainage tube and the ultrasonic detection probe 311 of the ultrasonic detection assembly. One end of the delivery tube 3212 is connected to the balloon head 3211. The delivery tube 3212 is mounted on the cable 312 of the ultrasonic detection assembly and the other end is connected to the other end of the cable 312 of the ultrasonic detection module. A filling port 322 is provided at the other end of the delivery tube 3212. Physiological saline is injected through the filling port 322 and delivered through the delivery tube 3212, allowing the balloon head 3211 to change from a contracted state to a filled state, so that it fits against the inner wall of the insertion section 11 of the drainage tube. This facilitates inspection by the ultrasonic detection probe 311 and ensures the accuracy of the inspection.

[0036] Further, if Figures 1 and 2 As shown, in this embodiment, the delivery tube 3212 is a hard tube, so that only the bag head 3211 is converted between the contracted state and the filled state, thereby improving efficiency and speed.

[0037] Further, if Figures 1 and 2 As shown, in this embodiment, when the balloon is inflated, the balloon head 3211 blocks the drainage port 2. This prevents large amounts of cerebrospinal fluid from being drained, which could cause changes in intracranial pressure and structural displacement, even if the balloon first passes through the lateral ventricle (filled with water) and then enters the hematoma cavity. This also protects the ultrasound probe from contamination.

[0038] Furthermore, in this embodiment, the real-time ultrasound detection drainage catheter of the embodiment of the present invention also includes: a limit block (not shown in the figure), which is connected to the ultrasound detection module and is used to limit the depth of insertion of the ultrasound detection module into the drainage tube, so that the ultrasound detection module can be inserted into the insertion section 11 of the drainage tube to ensure the accuracy of the detection.

[0039] When in use, physiological saline is filled through the filling port 322, and the physiological saline is transported through the delivery tube 3212, so that the bag head 3211 changes from a contracted state to a filled state, so that the bag head 3211 fits against the inner wall of the insertion section 11 of the drainage tube and blocks the drainage port 2, and the connector 313 is connected to the host for puncture. During puncture, the ultrasonic detection probe 311 transmits the detected real-time data to the host through the cable 312 for data display. After the puncture is completed, the bag head 3211 and the ultrasonic detection probe 311 are withdrawn together. At this time, the drainage port 2 is connected and drainage is performed.

[0040] Above, refer to Figures 1 and 2 The present invention, according to an embodiment of the present invention, can detect the situation ahead and the location and direction of the patient in real time through ultrasound after entering the brain tissue, providing extremely high accuracy for cranial puncture. Furthermore, before entering the brain tissue, drainage port 2 can be blocked to prevent excessive drainage of cerebrospinal fluid, which could cause changes in intracranial pressure and structural displacement, and to protect the ultrasound probe from contamination.
