Utility model content
Technical problem to be solved in the utility model is to provide a kind of band air bag flow-controllable lumbosacral spine puncturing drainage apparatus, the flexible catheter of this lumbosacral spine puncturing drainage apparatus more easily inserts spinal cavity, and can not fracture and slippage, accurately can also control cerebrospinal fluid flow.
This utility model solves the technical scheme that its technical problem adopts and is to provide a kind of band air bag flow-controllable lumbosacral spine puncturing drainage apparatus, comprise the trocar with outer casing needle and nook closing member, three-way valve, receive sample pipe and receive sample bag, described nook closing member is positioned at outer casing needle inside, a port of described three-way valve is connected with receipts sample pipe by mozzle, described receipts sample pipe is connected by mozzle with receipts sample bag, after described trocar puncture enters spinal cavity, exit nook closing member, the inner flexible catheter that seal wire is housed is inserted in described outer casing needle, the thickness of described seal wire and the internal diameter of flexible catheter match, after seal wire enters spinal cavity, exit outer casing needle, after guiding flexible catheter to enter spinal cavity by seal wire, exit seal wire, described flexible catheter is connected with another port of three-way valve, one end that described flexible catheter thrusts spinal cavity is provided with inflatable airbag, flow control valve is provided with between described three-way valve and receipts sample pipe.
Described flexible catheter tube wall is provided with the gas tube be communicated with air bag.
Described air bag is arranged on flexible catheter head end 6cm place.
Described seal wire front portion is the frustoconical on round and smooth top.
The stray circle center, top of described seal wire, is positioned at circumferential position.
Described flow control valve is arranged near three-way valve place.
Beneficial effect
The seal wire being furnished with thickness coupling when flexible catheter of the present utility model enters spinal cavity guides, the front portion of seal wire is pyramidal structure, flexible catheter is more easily inserted in outer casing needle, and seal wire is positioned at flexible catheter inside, can effectively prevents flexible catheter from being cut off by sharp outer casing needle syringe needle; The head end that flexible catheter thrusts spinal cavity gap arranges air bag, can play effect flexible catheter being fixed on spinal cavity gap after airbag aeration, makes flexible catheter in use slippage can not occur; Between three-way valve and receipts sample pipe, flow control valve is set, accurately can control the flow of cerebrospinal fluid, and this flow control valve can be arranged on the position near three-way valve, makes control structure in device compact.
Accompanying drawing explanation
Fig. 1 is that this utility model trocar inserts the structural representation after being furnished with the flexible catheter of seal wire.
Fig. 2 is the structural representation of this utility model puncturing drainage apparatus.
Wherein: 1 is outer casing needle, 2 is flexible catheter, and 3 is seal wire, and 4 is air bag, and 5 is gas tube, and 6 is three-way valve, and 7 is flow control valve, and 8 for receiving sample pipe, and 9 for receiving sample bag, and 10 is trocar.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth this utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of this utility model.In addition should be understood that those skilled in the art can make various changes or modifications this utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read this utility model instruction.
One band air bag flow-controllable lumbosacral spine puncturing drainage apparatus as illustrated in fig. 1 and 2, comprise trocar 10, three-way valve 6, receive sample pipe 8 and receive sample bag 9, trocar 10 is made up of outer casing needle 1 and nook closing member, it is inner that nook closing member is positioned at outer casing needle 1, a port of three-way valve 6 is connected with receipts sample pipe 8 by mozzle, receives sample pipe 8 and is connected by mozzle with receipts sample bag 9.
When carrying out lumbosacral spine puncture, after trocar 10 puncture enters spinal cavity, exit nook closing member, insert the flexible catheter 2 being furnished with seal wire 3 in outer casing needle 1, seal wire 3 is positioned at the inside of flexible catheter 2, and the internal diameter of thickness and flexible catheter 2 matches.After seal wire 3 enters spinal cavity, exit outer casing needle 1, after guiding flexible catheter 2 to enter spinal cavity by seal wire 3, exit seal wire 3, flexible catheter 2 is connected with another port of three-way valve 6.Seal wire 3 front portion is the frustoconical on round and smooth top, and the stray circle center, top of seal wire 3, be positioned at circumferential position.After being furnished with seal wire 3 in flexible catheter 2, flexible catheter 2 is not only more easily guided to enter in trocar 10, and seal wire 3 pairs of flexible catheters 2 play the effect of support, can effectively prevent from inserting, adjusting in the process of flexible catheter 2, flexible catheter 2 is cut off by the syringe needle of sharp outer casing needle 1, causes flexible catheter 2 to fracture and stays in patient's spinal cavity.
