Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a neurosurgical drainage device. Background Technique

[0002] Cranial fluid accumulation is one of the common diseases in clinical neurosurgery. At present, during treatment, a drainage device is usually used to extract the fluid accumulation in the cranium, so as to relieve the intracranial pressure of the patient and clarify the nature of the fluid accumulation. However, during drainage, the drainage tube may become blocked. If medical staff fail to detect the blockage of the drainage tube in time, it is likely to cause the failure of the drainage device, affect the drainage effect, and cause certain harm to the patient.

[0003] The patent with the application number 202022262434.2 discloses a neurosurgical cranial fluid accumulation drainage device, including a base. A suction pump is fixedly connected to the upper surface of the base. The air inlet end of the suction pump is fixedly communicated with a hose through a pipe joint. A cover plate is fixedly connected to the surface of the hose through a pipe joint. A bearing is fixedly connected to the surface of the cover plate, and an internally threaded ring is fixedly connected to the surface of the bearing. By setting a hollow cylinder, a pressing mechanism, a support block, a pressing switch and a buzzer, when the drainage tube is blocked, the air pressure in the bottle gradually decreases under the action of the suction pump. At this time, under the action of negative pressure, the rubber piston moves downward. When the pressing plate presses the pressing switch, the buzzer is turned on through the pressing switch. At this time, the buzzer sound generated by the buzzer plays a reminder role for the surrounding medical staff, so that medical staff can timely detect that the drainage tube is blocked.

[0004] The above-mentioned drainage device has the following deficiencies: when the drainage tube is blocked, the whole device gives an alarm for reminder. However, subsequent medical staff still need to use complex operations to replace or dredge the drainage tube. Utility Model Content

[0005] The purpose of the utility model is to provide a neurosurgical drainage device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a neurosurgical drainage device, including a base, a drainage bottle arranged on the upper surface of the base, a negative pressure pump and a drainage tube. A disinfection bottle is further arranged between the drainage bottle and the negative pressure pump on the upper surface of the base. The disinfection bottle is communicated with the drainage bottle through a first catheter, and the disinfection bottle is connected with the air inlet end of the negative pressure pump through a second catheter. One end of the drainage tube extends into the drainage bottle, and the other end of the drainage tube is provided with a suction tube through a connector, and a dredging component is arranged on the connector.

[0007] Preferably, the interior of the disinfection bottle is filled with a disinfectant solution, and the liquid level of the disinfectant solution is higher than the port of the first conduit.

[0008] Preferably, a chamber is formed inside the connector, the end of the suction tube extends into the chamber, and a one-way valve is installed at one end of the suction tube close to the chamber.

[0009] Preferably, the dredging assembly includes a third conduit and a fourth conduit. One end of the third conduit is communicated with the chamber of the connector, the other end of the third conduit is connected to the exhaust end of the negative pressure pump, the fourth conduit is connected to the third conduit, and a two-way three-way valve is installed at the connection.

[0010] Preferably, the port of the second conduit close to the disinfection bottle is above the disinfectant solution.

[0011] Preferably, the drainage bottle is entirely made of a transparent material, and a scale ruler is provided on the outer surface.

[0012] Preferably, the connector is detachably connected to the drainage tube, the suction tube, and the third conduit.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a connector at the upper end of the drainage tube, connecting the suction tube to the connector, and simultaneously providing a dredging assembly on the connector, with the two ends of the third conduit of the dredging assembly respectively connected to the chamber and the exhaust end of the negative pressure pump, during use, when the drainage tube becomes blocked, by rotating the two-way three-way valve of the dredging assembly, the air flow generated by the negative pressure pump enters the chamber and returns through the drainage tube, achieving rapid dredging of the drainage tube and avoiding the complex operation of replacing the drainage tube;

[0015] 2. By providing a disinfection bottle between the drainage bottle and the negative pressure pump, disinfecting the gas flowing out of the drainage bottle, preventing the air after contact and accumulation of liquid from entering the interior of the negative pressure pump and finally directly discharging it, ensuring clean air.
