Disposable lumbar cistern drainage and multidirectional shunting device

Abstract

The invention discloses a disposable lumbar cistern drainage and multidirectional shunting device, comprising a four-way shunt device. The four-way shunt device comprises a three-way valve and an adjusting knob. The disposable lumbar cistern drainage and multidirectional shunting device is characterized in that the four-way shunt device is connected with a sample collection channel, an intrathecal injection channel, a cerebrospinal fluid collection channel and a fluid incoming channel; the intrathecal injection channel is provided with a seal rubber gasket fluid inlet; the fluid incoming channel is connected with a lumbar cistern drainage channel; the tail end of the sample collection channel is provided with a positive pressure valve; a spring is compressed on the positive pressure valve; a one-way valve is compressed to the other end of the spring through a one-way valve support cross-beam; the cerebrospinal fluid collection channel is connected with a cerebrospinal fluid collector. The disposable lumbar cistern drainage and multidirectional shunting device is capable of isolating germs, avoiding iatrogenic contaminations and preventing cerebrospinal fluid sample contamination, thereby improving accuracy of sample inspection; is convenient to operate; and has the functions of cerebrospinal fluid collecting, cerebrospinal fluid sampling and intrathecal injection.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable multidirectional shunt device for lumbar cistern drainage. Background technique [0002] Patients with cerebral hemorrhage after neurosurgery or neurology often have intracranial hemorrhage, hydrocephalus or intracranial infection, and usually need to drain the bloody or infectious cerebrospinal fluid through lumbar cistern drainage, and the cerebrospinal fluid can be retained Specimens are sent for inspection, and the treatment plan is adjusted according to the inspection results. At the same time, lumbar cistern drainage can also be injected intrathecally, which has a certain effect on controlling infection. The lumbar cistern drainage bag is a medical device connected to the lumbar cistern continuous drainage tunnel to drain and collect the cerebrospinal fluid in the lumbar cistern. It is also widely used clinically for external ventricular drainage. Lumbar drainage needs to ...

AI Technical Summary

Problems solved by technology

However, the continuous drainage bag of the lumbar cistern in the past only has the function of collecting cerebrospinal fluid. To collect specimens or intrathecal injection, the only way is to open the sterile connection between the drainage bag and the drainage tunnel. Such an operation is extremely inconvenient and prone to contamination. Allow bacteria to enter the central nervous system during operation and cause iatrogenic infection of the central nervous system

Once iatrogenic infection occurs, it will prolong the patient's hospital stay, cause the patient's physical and mental pain, and increase the patient's economic burden
