Abstract

A Novel anesthesia syringe is the scale that is provided with needle-insertion positioning device and shows depth of needle on needle tubing; Can and show a kind of Novel anesthesia syringe that depth of needle is accurate, controlled, adjustable to depth of needle location.It is characterized in that: on needle tubing, be provided with inserting needle scale, medicinal liquid scale, flexible sliding sleeve, the excircle of needle tubing has external screw thread, and external screw thread has the female thread of the positioning sleeve being mated, and the outer surface of positioning sleeve has convex-concave ring.This Novel anesthesia syringe, can accurately set and adjust depth of needle at any time, can conveniently observe and control depth of needle; Anaesthetic can reach the presumptive area needing most, and makes anesthesia reach optimum efficiency; Also can when inserting needle, keep needle tubing stable, syringe needle direction be constant; Make syringe needle accurately be deep into predetermined anesthesia district, anaesthetist's rapid operation, hand-held stable.Its structural design of this utility model is novel, practical, scientific and reasonable, is applicable to very much Ji Ge section office of situation of all-level hospitals Anesthesia Department and promotes the use of.

Description

Novel anesthesia syringe

Technical field

This utility model relates to a kind of anesthetic syringe, particularly relates to the scale that is provided with needle-insertion positioning device and shows depth of needle on needle tubing; Can and show a kind of Novel anesthesia syringe that depth of needle is accurate, controlled, adjustable to depth of needle location.

Background technology

Anesthesia is the forfeiture of sensation, consciousness, and the forfeiture of its sensation, consciousness can be local, can be also the forfeiture of whole body; From the angle of medical science, the meaning of anesthesia is to make the local or whole swound of human or animal by medicine, to reach painless or unconscious, for operation or medical examination provide essential condition; The quality of anaesthetic effect, the time length of anesthesia, directly impact operation or medical examination normally carries out.Anesthetic syringe is the important utensil that anaesthetist uses, and general anesthetic syringe, the bad control of depth of needle, does not have depth of needle scale; And can only rely on anaesthetist's experience and feel to remove to control depth of needle, and its operation is difficult, and it is inaccurate that depth of needle is controlled, and anaesthetist's work difficulty is strengthened.

Summary of the invention

In view of the above problems, the utility model proposes a kind of Novel anesthesia syringe; On needle tubing, be provided with the scale of depth of needle positioner and demonstration depth of needle, can and show depth of needle location; Can set again and adjust depth of needle at any time, can conveniently observe and control depth of needle; Anaesthetic can reach the presumptive area needing most, and makes anesthesia reach optimum efficiency.

The technical scheme that this utility model adopts is: Novel anesthesia syringe, has needle tubing, tube head gear, syringe needle, piston, push rod; It is characterized in that: on the outer wall of needle tubing, have inserting needle scale, medicinal liquid scale, have the excircle of one of the needle tubing of syringe needle to have flexible sliding sleeve, the needle point that flexible sliding sleeve length equals syringe needle is to the length between 0 line of inserting needle scale; The excircle of needle tubing has external screw thread, and external screw thread has the female thread of the positioning sleeve being mated; The outer surface of positioning sleeve has convex-concave ring.

This Novel anesthesia syringe, in use, first observes inserting needle scale, the scale the rotation of positioning sleeve left end to predetermined depth of needle, then the right-hand member of flexible sliding sleeve is pulled to outside 0 line of inserting needle scale; Now, arrest on the other hand flexible sliding sleeve, hold on the other hand positioning sleeve, the left end of flexible sliding sleeve is withstood on to the surface, anesthesia injection zone of choosing, hold the have gentle hands of positioning sleeve and gently exert oneself, syringe needle is thrust; The right-hand member that withstands on flexible sliding sleeve to positioning sleeve left end stops, and now, the needle point of syringe needle has reached predetermined depth of needle, then coordinates observation medicinal liquid scale, anesthetis is pushed to the dosage of regulation.As needs are deeply anaesthetized again, can rotate again positioning sleeve, coordinate and observe inserting needle scale, to the left end of positioning sleeve, rotate to the scale of the depth of needle needing, then operate more than again.

This Novel anesthesia syringe is provided with depth of needle positioner and the scale that shows depth of needle on needle tubing, can be to accurately location and demonstration of depth of needle; Its flexible sliding sleeve withstands on skin surface, also can when inserting needle, keep needle tubing stable, and syringe needle direction is constant, makes syringe needle accurately be deep into predetermined anesthesia district; The convex-concave ring of its positioning sleeve outer surface, also can increase frictional force, makes anaesthetist's rapid operation, hand-held stable.This Novel anesthesia syringe, can accurately set and adjust depth of needle at any time, can conveniently observe and control depth of needle, and depth of needle is accurate, controlled, adjustable; Anaesthetic can reach the presumptive area needing most, and makes anesthesia reach optimum efficiency; Its structural design is novel, practical, scientific and reasonable, is applicable to very much Ji Ge section office of situation of all-level hospitals Anesthesia Department and promotes the use of.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Figure of description is the overall structure figure of this utility model embodiment.

In figure: 1. syringe needle, 2. piston, 3. inserting needle scale, 4. positioning sleeve, 5. female thread, 6. external screw thread, 7. needle tubing, 8. tube head gear, 9. push rod, 10. medicinal liquid scale, 11. convex-concave rings, 12. flexible sliding sleeves.

The specific embodiment

In Figure of description, this Novel anesthesia syringe, has needle tubing, tube head gear, syringe needle, piston, push rod; It is characterized in that: on the outer wall of needle tubing (7), have inserting needle scale (3), medicinal liquid scale (10), have the excircle of (7) one of the needle tubings of syringe needle (1) to have flexible sliding sleeve (12), the needle point that the length of flexible sliding sleeve (12) equals syringe needle (1) is to the length between 0 line of inserting needle scale (3); The excircle of needle tubing (7) has external screw thread (6), and external screw thread (6) has the female thread (5) of the positioning sleeve (4) being mated; The outer surface of positioning sleeve (4) has convex-concave ring (11).

In figure, this Novel anesthesia syringe, the material of using, except syringe needle (1), is all used medicinal non-toxic transparent plastic manufacture.

In figure, this Novel anesthesia syringe, in use, first observes inserting needle scale (3), the scale the rotation of positioning sleeve (4) left end to predetermined depth of needle, then the right-hand member of flexible sliding sleeve (12) is pulled to outside 0 line of inserting needle scale (3); Now, arrest on the other hand flexible sliding sleeve (12), hold on the other hand positioning sleeve (4), the left end of flexible sliding sleeve (12) is withstood on to the surface, anesthesia injection zone of choosing, hold the have gentle hands of positioning sleeve (4) and gently exert oneself, syringe needle (1) is thrust; The right-hand member that withstands on flexible sliding sleeve (12) to positioning sleeve (4) left end stops, and now, the needle point of syringe needle (1) has reached predetermined depth of needle, then coordinates observation medicinal liquid scale (10), anesthetis is pushed to the dosage of regulation.As needs are deeply anaesthetized again, can rotate again positioning sleeve (4), coordinate and observe inserting needle scale (3), to the left end of positioning sleeve (4), rotate to the scale of the depth of needle needing, then operate more than again.
