Abstract
The utility model relates to the range of medical instruments, in particular to a side hole lumbar puncture device. The needle point hole is closed, the needle hole is close to the side surface of the needle point, the side hole can prevent the needle tube from being blocked, so that a needle core is not needed, the opening end of the needle tube is directly communicated with a three-way tube, and a pressure measuring hole of the three-way tube and an injection hole are provided with a rubber plug which can be self-sealed. The side hole lumbar puncture device is convenient and safe to operate and low in cost.
Description
This utility model relates to the category of medical apparatus and instruments, particularly a kind of side opening lumbar puncture device.
By the lumbar puncture needle that needle tubing and nook closing member are formed, the effect of nook closing member is to prevent that needle tubing from being stopped up by soft tissue.Nook closing member must be extracted after waist is worn successfully out and pressure-measuring pipe or syringe could be connected, not only operation inconvenience, and always have the spinal fluid spray to leak phenomenon in the process of extraction nook closing member, produce unsafe factor.
Be head it off import swivel tee switch in recent years, pressure-measuring pipe or syringe can be connected by three-way cock and lumbar puncture needle.But could connect three-way cock after operation the time still will be extracted nook closing member out, and swivel tee switch complex process, cost height.
The purpose of this utility model is that a kind of improved side opening lumbar puncture device will be provided, and it is convenient to operation, and is safe, inexpensive.
The purpose of this utility model is achieved in that the needle point sealing of lumbar puncture needle, and pin hole is in the side near needle point, and side opening can avoid soft tissue to stop up needle tubing, so need not nook closing member in the needle tubing.Owing to there is not nook closing member, needle tubing just can be connected with a kind of transparent tee T before waist is worn.The pressure tap of tee T and injection orifice have the rubber stopper sealing respectively.During pressure measurement with the lancet puncture plug of pressure-measuring pipe, during injection with the syringe plug that punctures.
This utility model only needs the pin hole of lumbar puncture needle is opened in the side near needle point, and the cone head hole of the other end and tee T is connected.Because of there not being nook closing member, without the drawn needle core, leak during operation, and pressure tap all has rubber stopper self-styled with injection orifice so can prevent the spinal fluid spray, connect by puncture during operation, extract out again and seal automatically, operate easier, simple in structure, cost is low.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the side opening lumbar puncture device that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
Side opening lumbar puncture device comprises a main body needle tubing (1), and near the rarest side opening in needle point place (2), the body openings end communicates with the taper hole (4) of tee T (3) in main body.
Spinal fluid is in side opening (2) enters needle tubing (1) and transparent tee T (3) after waist is worn successfully.Pressure-measuring pipe (4) puncture pressure measuring hole plug (5) but pressure measurement, it is self-styled to extract the pressure-measuring pipe plug out.Syringe (not drawing among the figure) puncture injection hole plug (6) can be injected, and it is self-styled to extract syringe plug glue out.
Claims (3)
1, a kind of side opening lumbar puncture device, this device has a needle tubing (1) and tee T (3), it is characterized in that lumbar puncture needle has only a needle tubing (1), near the rarest pin hole in the side of needle point.
2, device according to claim 1 is characterized in that the pressure tap of tee T (3) and injection orifice use plug (5), (6) sealing respectively.
3, device according to claim 1 and 2 is characterized in that needle tubing (1) directly communicates with tee T (3).
