Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with specific embodiments.

[0012] The device of the present invention includes a lumbar puncture needle sheath 1, and the lumbar puncture needle sheath 1 is marked with scales for marking the needle penetration depth. The back of the lumbar puncture needle sheath 1 has a cerebrospinal fluid replacement discharge port 2 that opens to the side, where a three-way connector 3 is connected, and the opening direction of the three-way can be adjusted as needed, so that one port of the three-way connector 3 is used for outflow of cerebrospinal fluid (or Intrathecal injection), the other port is used to connect a brain pressure gauge or a pressure tube, and the injection speed of normal saline can be adjusted according to the intracranial pressure. The end of the lumbar puncture needle sheath 1 is blocked by an elastic rubber blocking pad 4, and the rubber blocking pad 4 has a hole in the center, through which...

Abstract

The invention discloses a device for post lumbar puncture cerebrospinal fluid replacement. The device comprises a lumbar puncture needle sheath, wherein the lumbar puncture needle sheath is graduated;a cerebrospinal fluid replacement outlet opened sidewards is formed in the rear part of the lumbar puncture needle sheath and is connected with a three-way joint; the tail end of the lumbar punctureneedle sheath is blocked by an elastic rubber blocking pad; a hole is formed in the center of the rubber blocking pad; a puncture needle core and a cerebrospinal fluid replacement flusher can be penetrated from the hole in a forward direction, and the hole is elastically sealed when the puncture needle core and the cerebrospinal fluid replacement flusher have no need to be penetrated; the cerebrospinal fluid replacement flusher is a needle-shaped and hollow metal part; a plurality of holes are formed in the head end of the cerebrospinal fluid replacement flusher; the tail end of the cerebrospinal fluid replacement flusher is connected with a high-capacity injector through a PVC (Polyvinyl Chloride) connecting pipe; a liquid switch clip is also arranged on the PVC connecting pipe. The device for post lumbar puncture cerebrospinal fluid replacement provided by the invention has the beneficial effects of simple structure, simplicity and convenience in operation, and high replacement efficiency.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and relates to a device for cerebrospinal fluid replacement after lumbar puncture. Background technique [0002] Cerebrospinal fluid replacement is widely used in clinical practice and has great clinical significance. However, the traditional cerebrospinal fluid replacement operation is cumbersome. After successful lumbar puncture, the intracranial pressure needs to be injected into the subarachnoid space with a syringe (replacement fluid). The normal saline is mixed for about 1-2 minutes, and then the same amount of diluted cerebrospinal fluid is drawn back, and then discarded. Repeat this operation to meet the replacement requirements. In this process, due to repeated withdrawal and injection operations, the intracranial pressure is likely to fluctuate greatly and even induce brain herniation; in addition, the operation time is long, the patient's tolerance is poor, the medical staff is pron...
