Collection tube used for cerebrospinal fluid replacement

Abstract

The invention belongs to the technical field of medical instruments and equipment, and particularly relates to a collection tube used for cerebrospinal fluid replacement. The top end of the collection tube body is connected with a collection port having a tunnel structure. Gaskets having a symmetrical structure are fixedly manufactured at the side surfaces of the collection port. A flexible handle is flexibly connected with the collection port via the two gaskets. Scales are printed on the external side wall of the middle part of the collection tube body. A liquid outlet is fixedly manufactured at the center of the lower end part of the collection tube body. A tilting type liquid outlet cover used in cooperation with the liquid outlet is manufactured at the liquid outlet. The collection tube used for cerebrospinal fluid replacement is directly hung on a puncture needle used for cerebrospinal fluid replacement via the flexible handle, and cerebrospinal fluid is directly discharged from the liquid outlet so that collection of cerebrospinal fluid specimens is facilitated, damage to cells in cerebrospinal fluid is reduced, the number of times of crossing the puncture needle used for cerebrospinal fluid replacement of the collection tube body is reduced and aseptic operation environment for cerebrospinal fluid replacement is guaranteed. The collection tube used for cerebrospinal fluid replacement is simple in main structure, convenient to operate and use, friendly in use environment and suitable for large-scale popularization and use.

Description

Technical field: [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a collection tube for cerebrospinal fluid replacement to replace the existing common collection tube. Background technique: [0002] The principle of cerebrospinal fluid replacement is to replace bloody cerebrospinal fluid or inflammatory cerebrospinal fluid in the spinal canal by injecting an equal amount of sterile normal saline into the subarachnoid space, and finally inject dexamethasone into the spinal canal. The injected normal saline can reduce intracranial Keep the pressure relatively stable, dilute the cerebrospinal fluid, speed up the clearance of subarachnoid hemorrhage, relieve the irritation of meninges and nerve roots, reduce the occurrence of cerebral vasospasm and hydrocephalus, and inject dexamethasone to reduce exudation , prevent arachnoid adhesions, reduce cerebral edema. The cerebrospinal fluid collection tube currently used clinically...
