Abstract
The utility model discloses an anesthesia syringe, which comprises a syringe cylinder, a syringe needle, a push-pull rod, a piston and a push framework, wherein the syringe needle is connected with the syringe cylinder, the piston is arranged in the syringe cylinder, the push-pull rod is connected with the piston, the push framework is connected with the syringe cylinder, the push framework is provided with a screw rod, the screw rod is connected with the push framework through threads, one end of the screw rod is movably connected with a retaining plate, and the other end of the screw rod is provided with a rotary knob. When the anesthesia syringe is used, firstly, an anesthetist sticks the syringe needle into the body of a patient, and then rotates the rotary knob on the screw rod of the push framework, and anesthetic is injected into the body by the push-pull rod under the action of the retaining plate, so the accuracy of the dosage of the anesthetic is greatly ensured, the pain of the patient is greatly reduced, and meanwhile, the workload of the anesthetist is reduced.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of anesthetic needle.
Background technology
At present, healthcare structure at different levels all need the patient is anaesthetized before operation, and the anaesthetist must determine required narcotic amount modestly when the patient is anaesthetized; If consumption is very few, can cause suffering to the patient, if consumption is too much, can cause the patient to go into a coma.
The anaesthetist is when using existing anesthetic needle, just simply by the anesthesia procedure of the push rod realization on the promotion anesthetic needle to the patient; Because the anaesthetist relies on the strength of finger to promote push rod on the anesthetic needle fully, is easy to occur the very few or too much problem of anesthetis consumption, has brought great misery to the patient, has increased anaesthetist's work difficulty simultaneously.
Summary of the invention
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of simple in structure, practical and can guarantee fix amount anesthetic needle accurately.
Technical scheme
A kind of anesthetic needle of the present utility model comprises syringe, syringe needle, push-pull bar and piston; Described syringe needle is connected with syringe; Described piston is arranged in the syringe; Described push-pull bar is connected with piston; Also comprise the propelling frame; Described propelling frame is connected with syringe; Described propelling frame is provided with screw rod; Described screw rod is connected with advancing frame by screw thread; Described screw rod one end is connected with baffle plate; The described screw rod other end is provided with knob.
Further, described syringe is provided with scale.
Further, described piston is rubber piston.
Further, described propelling frame, screw rod, baffle plate and knob are plastic.
(3) beneficial effect
This utility model is compared and prior art, and it has following beneficial effect:
Of the present utility model a kind of simple in structure, practical and can guarantee the anesthetic needle that the fix amount is stable; When using this utility model, at first the anaesthetist is thrust syringe needle in patient's body, gets final product by the knob that rotates on the screw rod that advances frame then; Push-pull bar can be injected into anesthetis in patient's body under the promotion of baffle plate; Because this utility model is not to rely on strength that the anaesthetist points to promote push rod on the anesthetic needle simply, has guaranteed the accuracy of anesthetis consumption to a great extent, has alleviated patient's misery to a great extent, has reduced anaesthetist's workload simultaneously.
Description of drawings
Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, wherein:
Fig. 1 is constructional device figure of the present utility model;
Wherein, the 1-syringe, 2-advances frame, 3-screw rod, 4-syringe needle, 5-baffle plate, 6-piston, 7-push-pull bar, 8-knob.
The specific embodiment
A kind of anesthetic needle as shown in Figure 1 comprises syringe 1, syringe needle 4, push-pull bar 7 and piston 6; Described syringe needle 4 is connected with syringe 1; Described piston 6 is arranged in the syringe 1; Described push-pull bar 7 is connected with piston 6; Also comprise and advance frame 2; Described propelling frame 2 is connected with syringe 1; Described propelling frame 2 is provided with screw rod 3; Described screw rod 3 is connected with advancing frame 2 by screw thread; Described screw rod 3 one ends are connected with baffle plate 5; Described screw rod 3 other ends are provided with knob 8.
Wherein, described syringe 1 is provided with scale; Described piston 6 is rubber piston; Described propelling frame 2, screw rod 3, baffle plate 5 and knob 8 are plastic.
Of the present utility model a kind of simple in structure, practical and can guarantee the anesthetic needle that the fix amount is stable; When using this utility model, at first the anaesthetist is thrust syringe needle in patient's body, gets final product by the knob that rotates on the screw rod that advances frame then; Push-pull bar can be injected into anesthetis in patient's body under the promotion of baffle plate; Because this utility model is not to rely on strength that the anaesthetist points to promote push rod on the anesthetic needle simply, has guaranteed the accuracy of anesthetis consumption to a great extent, has alleviated patient's misery to a great extent, has reduced anaesthetist's workload simultaneously.
Embodiment recited above is described preferred implementation of the present utility model, is not that design of the present utility model and scope are limited.Under the prerequisite that does not break away from this utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents that this utility model is asked for protection all is documented in claims.
