Abstract

The utility model relates to a lumbar vertebra and ventricle puncturing needle for babies. The front end of the needle body of the puncturing needle has no inclined planes; the needle tip part of the front end of a needle core which is arranged in the needle body is exposed of the needle body; the tail part of the needle body is sheathed with a needle handle which is made of hard transparent plastics; a plastic foil which can move up and down is also arranged on the needle body; a set screw is arranged in a foil cover; the needle body is marked with scale lines and warning limit lines; a drainage tube is inserted in the needle handle. The puncturing needle has the advantages of small volume, light weight, the injury and the pain of the body tissues of diseased babies lightening and the success ratio of lumbar vertebra and ventricle puncture enhancing.

Description

Puncturing needle for children lumbar vertebra and brain

This utility model belongs to a kind of lumbar vertebra, the dual-purpose puncture needle of the ventricles of the brain.

Existing children's's brain puncture needle is to carry out ventricular puncture with adult's lumbar puncture needle, needle body is oversize, it is long to expose the brain outer body, the metal needle handle is overweight, and utilize the penicillin bottle cap to be fixed on the scalp and (consult 177 pages of " practical paidonosology " first volumes as stationary support, publish in Beijing, People's Health Publisher, 1985 the 4th edition), because the penicillin lid is misfitted with scalp, be difficult for fixingly, swing easily and collision and injured brain tissue, the puncture needle needle body does not have the scale sign in addition, can only transfer to the back to measure in the pin heart and understand depth of needle indirectly, so both time expand, increase sick child's misery had been polluted needle point again easily and has been caused the ventricles of the brain to infect.Also be to carry out lumbar puncture now, also have the problems referred to above with adult's lumbar puncture needle with children's's lumbar puncture needle.Now use lumbar vertebra and brain puncture needle needle body front end inclined-plane too big in addition, so a frequent inclined-plane part is in subarachnoid space or Intraventricular when puncture, another part causes puncture and is difficult for successfully flowing out not smooth with cerebrospinal fluid or ventricular fluid outside the subarachnoid space or the ventricles of the brain.

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of dual-purpose puncture needle of children's's lumbar vertebra, the ventricles of the brain of light easy row is provided.

This utility model is achieved in that it by needle body, the pin heart, and needle body handle and pin heart handle are formed, needle body front end slope-less, and the pin heart is through in the needle body, and pin apex of the heart distal process, penetrates in the skin histology with this as needle point for the needle body front end, realizes the puncture purpose.

Graduation mark and warning line are arranged on the needle body described in the utility model, be used for observing depth of needle, restriction is inserting needle blindly, has positioning component (only using when ventricular puncture) on the needle body, fix the needle body position, the connection tube of using when being used for puncture drainage is plugged in the needle body handle.

This utility model is compared following advantage with existing puncture needle: in light weight, volume is little, improved waist wears success rate and efficient with ventricular puncture, has reduced damage and misery to patient's body tissue, makes the disease can access early diagnosis and therapy.

Description of drawings:

Fig. 1 is the dual-purpose puncture needle structural representation of children's's lumbar vertebra, the ventricles of the brain.

Fig. 2 is children's's lumbar vertebra, the dual-purpose puncture needle needle body of ventricles of the brain front view.

Fig. 3 is needle handle and drainage tube partial structurtes cutaway view.

Further specify this utility model below in conjunction with accompanying drawing:

By the children's's lumbar vertebra shown in the figure (1), the dual-purpose puncture needle of the ventricles of the brain, needle body (1) is that thin metallic tubd is made, the pin heart (3) is the solid metal pin, it comprises needle point (4) and pin heart handle (5), be through in the needle body (1), cooperate closely, pin apex of the heart end (4) exposes needle body (1), realize puncture with this, needle handle (2) is that hard transparent plastic is made, and is fixed on needle body (1) afterbody, and keeper is made up of rigid plastics thin slice (6) and dog screw (7), be enclosed within on the needle body (1) and can move up and down, tighten screw and locate, needle body (1) is marked with graduation mark (8) and warning line (9) (shown in the figure (2)), is directly acquainted with depth of needle and restriction blindness inserting needle with this, figure shown in (3) is the annexation structural representation of needle handle (2) and the drainage tube (10) manufactured by lucite pipe, utilizing transparent tube is situation when being convenient to observe injectable drug and drain, when drain, transfers to the pin heart (3), drainage tube (10) inserts the afterbody of needle handle (2), can realize drain.

Claims

1, a kind of children's's lumbar vertebra, the dual-purpose puncture needle of the ventricles of the brain, it comprises the needle body (1) and the pin heart (3), it is characterized in that needle body front end slope-less, and pin apex (4) is exposed needle body (1), and needle body (1) is marked with graduation mark (8) and warning line (9).

2, children's's lumbar vertebra according to claim 1, the dual-purpose puncture needle of the ventricles of the brain is characterized in that being with on the needle body (1) a removable and plastic tab slightly concave surface (6) up and down, and dog screw (7) is housed on the thin slice.

3, children's's lumbar vertebra according to claim 1, the dual-purpose puncture needle of the ventricles of the brain is characterized in that needle handle (2) and drainage tube (10) are the relations of pegging graft, and wherein needle handle (2) is that hard transparent plastic is made, and drainage tube (10) is that transparent plastic is made.
