A kind of anesthesia procedure analogue means

Technical field

The present invention relates to a kind of anesthesia outfit, specifically is a kind of anesthesia procedure analogue means, belongs to the medical educational technical field.

Background technology

Anesthesia is clinical operation prerequisite and basis; The method of anesthesia mainly contains clinically: intravertebral anesthesia (comprising caudal anaesthesia, lumbar anesthesia, sacrum fiber crops etc.), nerve block anesthesia (comprising cervical plexus, brachial plexus, lower limb nerve retardance etc.); General anesthesia (Intravenous Anesthesia, suction anesthesia, quiet suction combined anesthesia etc.), anesthetic puncture and intravenous injection are the basic fundamentals of anesthesia procedure.

Anesthesia procedure is clinical basic skills; The operation of study anesthesia is but very difficult, and former exercise can only be at the hospital clinical operative site, by teacher's operation and to student explain; The student can not directly operate, and the realistic model of rising in recent years can effectively assist the student to carry out the anesthesia procedure exercise.Present anesthesia procedure model is divided into simple model and computer-controlled model; Simple model is only paid attention to puncture or injection exercise; But can not realize puncturing or injecting informing of putting in place, computer control only can realize sucking the simulation of anesthesia, and the both can't realize the injection of anestetic needle and the tight association of model; Can't realize the indication in each stage of process of injecting anesthetic, the sense of reality that the student participates in reduces greatly; If anesthesia liquid is adopted in puncture of injecting anesthetic simultaneously or injection exercise, because the manufacturing technology of anesthesia procedure model emulation tissue and the restriction of material are punctured several times and will be revealed through too small amount, thereby can't proceed the operation training of anesthesia procedure.How to realize that the anesthesia procedure model can stand the exercise of repeatable operation training and can inform automatically that each process of anesthesia is present urgent problem.

Summary of the invention

To the problem that above-mentioned prior art exists, the present invention provides a kind of anesthesia procedure analogue means, can use repeatedly; Need not dispose anesthesia liquid; Realize the injection of anestetic needle and the tight association of model, and the indication in each stage of process of injecting anesthetic, the sense of reality of raising simulated operation.

To achieve these goals; The present invention realizes by the following technical programs: a kind of anesthesia procedure analogue means; Comprise the anestetic needle that constitutes by piston push rod, syringe and syringe needle; And demonstration and control circuit; The side correspondence of piston push rod is provided with the piston push rod hard contact, and the inboard of syringe is provided with anesthesia liquid indication hard contact and operation completion indication hard contact, and anesthesia liquid indication hard contact, operation are accomplished and indicated hard contact and piston push rod hard contact all to be electrically connected with control circuit with demonstration by power line; Demonstration is installed on the simulation human body and by master switch with control circuit and is electrically connected with power supply; In demonstration and the control circuit; Power supply indicator directly is electrically connected with master switch; Ready light is electrically connected with power supply by anesthesia liquid indication hard contact, and the puncture indicator lamp is electrically connected with power supply by pressure sensor, and the injection indicator lamp is accomplished the indication hard contact by operation and is electrically connected with power supply.

The invention has the beneficial effects as follows: directly perceived, convenient, durable; Exercise and the anesthesia parenteral solution that can directly realize anesthesia procedure extracts, puncture puts, injects completion in place and the successful process of anesthesia is informed, realizes the injection of anestetic needle and the tight association of operation model, can use repeatedly; Need not dispose anesthesia liquid; The problem that does not exist puncture to reveal can let the student accomplish the study of anesthesia procedure in the laboratory, effectively improves the sense of reality of student's simulated operation.
