Abstract
A kind of lumbar puncture needle, relates generally to technical field of medical instruments.This utility model only has a nook closing member to solve existing lumbar puncture needle, and operating process cerebrospinal fluid easily sprays, and drug delivery process is complicated, and easily forms cross infection, can not accurate assurance paracentesis depth in operation, repeatedly punctures, and patient pain feels the problem such as strong.This utility model adopts L shape nook closing member, is provided with oblique glass resistance sheet, cerebrospinal fluid is not easily entered, thus not easily forms cross interference at nook closing member fore-end.Nook closing member does not need to extract out completely, then after having gathered cerebrospinal fluid, can facilitate drug delivery.Needle body lateral wall is marked with scale, can grasp paracentesis depth preferably.Surveying cranium pressure instrument can Real-Time Monitoring cerebrospinal pressure, to control its excessive flow velocity.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments---lumbar puncture needle.
Background technology
Lumbar puncture needle is the detection commonly used of doctor and medical instrument.Existing lumbar puncture needle only has a nook closing member, and in operating process, cerebrospinal fluid easily sprays, and drug delivery process is complicated, and easily forms cross infection, can not accurate assurance paracentesis depth in operation, and repeatedly puncture, patient pain feels strong.
Summary of the invention
It is simple that this utility model object is to provide a kind of structure, lumbar puncture needle easy to use.
The technical solution of the utility model is a kind of lumbar puncture needle, and it includes needle body 1, nook closing member 2 and needle stand 3, it is characterized in that: described needle body 1 is hollow circular cylinder, and its one end is bell, and the other end is fixedly connected with needle stand 3.Nook closing member 2 is L shape, and part is disposed across in needle body 1.
The technical solution of the utility model can also be that described needle body 1 outer wall is marked with scale 1-1, be equipped with and survey cranium pressure instrument 1-2, and have a chute 1-3, needle body 1 interior lower surface has 2 support 1-4, there is a draining hole 1-5 at lower surface tail end place, connect rubber tube 4 under draining hole, rubber tube 4 with soon receive collector and be connected, and to have in the built-in rubber tube of bead 4-1.
The beneficial effects of the utility model are that the described nook closing member 2 side inwall that punctures is provided with oblique glass resistance leaf 2-1, and lower end, nook closing member corner is provided with rubber blanket 2-2, and standing portion has scale 2-3.During use, promote nook closing member and puncture, control paracentesis depth by needle body chapter, the chute degree of depth is about less than the distance of nook closing member head to needle body head, and ensureing that nook closing member thrusts can not be too much.After acupuncture success, retracting the suitable distance of nook closing member, checking pressure size by surveying cranium pressure table, and overflow speed, in case cerebral hernia occurs in too fast outflow by the bead control cerebrospinal fluid controlled in drainage tube.When gathering cerebrospinal fluid, exist because there is oblique glass to hinder sheet, cerebrospinal fluid not easily enters in nook closing member, thus greatly reduces cross infection.After collecting fixed amount cerebrospinal fluid, again push nook closing member, now, the dead draining hole of rubber rubber seal of lower end, nook closing member corner, cerebrospinal fluid no longer outflows, and injection of medicine, to treat, controls injection rate by scale in pipe simultaneously from standing portion glass tubing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the beneficial effects of the utility model have a nook closing member in described needle body 1, and needle body tail end has needle stand.Nook closing member is L shape, and have oblique glass to hinder sheet in its puncturing head, corner is provided with rubber blanket.Needle body tail end has draining hole, and there is chute upper end, graduation apparatus and pressure gauge.
When using nook closing member puncture, touch and erect glass tubing to fluting place, cerebrospinal fluid namely can be excessive in rubber tube along body chamber, then collected by collecting pipe.When pressure is excessive, when spill-out is excessive, by bead controllable flow speed in rubber tube.
After collecting cerebrospinal fluid, again push nook closing member, and by erectting glass tubing injection.Dose is observed by pipe outer wall high scale, and hinder sheet because there being oblique glass at nook closing member puncturing head place and exist, its flow velocity is generally slow.There is rubber blanket lower end, nook closing member corner, cerebrospinal fluid can be stoped to continue excessive.Structure of the present invention is simple, easy to use.
