Embodiment Construction

[0019] As shown in the accompanying drawings, the teaching simulation syringe created by the present invention consists of an outer sleeve 2, an inner sleeve 3, and a piston 1 that is movable and arranged in the inner sleeve, a one-way valve 4, and a communication valve device 6 The Unicom valve device includes a sealing plug 9, a Unicom valve main body 10, and a conduit 11, which are used to communicate and close the connection between the Unicom outer sleeve 2 and the inner sleeve 3 spaces, and can pass through the Unicom valve main body to the outer sleeve 2 and the inner sleeve. Liquid is injected into the sleeve 3; there is an air hole 12 at the top of the outer sleeve 2, the diameter of which is less than 0.1 mm; and a simulated needle 5 can be included.

[0020] Connect the analog needle 5 to the cone 13 of the inner sleeve through the one-way valve. If the one-way valve 4 allows the liquid to enter the inner sleeve 3 through the needle, the sealing plug 9 can be tightly...

Abstract

The invention discloses a teaching simulation injector, and the injector consists of an external sleeve, an internal sleeve, a piston which is disposed in the internal sleeve in a movable fit manner, a one-way valve, and a communication valve device. The communication valve device comprises a sealing plug, a communication valve main body, and a conduit. The communication valve device is used for communicating the external and internal sleeves and cutting off the connection of the external and internal sleeves, and can inject liquid into the external and internal sleeves through the communication valve main body. The injector also comprises a simulation probe. The direction of the one-way valve can be changed for use. The top of the external sleeve is provided with a gas hole, wherein the diameter of the gas hole is less than 0.1mm. The injector can effectively prevent the contact with a sensor or circuit in a model from causing the short-circuit potential safety hazard, and can simulate the clinic puncture training.

Description

technical field [0001] The invention relates to a teaching syringe, in particular to a teaching simulation syringe which can choose not to discharge liquid from an injection needle hole, but can also simulate liquid discharge. Background technique [0002] In the process of medical teaching, when students practice puncture, injection, suction and other operational skills, they must first judge the position and depth of acupuncture, so as to avoid unnecessary damage to patients. The simulation model used in the actual training is often equipped with a certain number of sensors, circuit boards and other electrification devices. In addition, the materials currently used cannot withstand multiple punctures, otherwise it will leak water. If the user does not pay attention, the circuit will be damaged. Short circuit phenomenon, resulting in certain safety hazards. For this reason, the model designer also often adjusts the position of the circuit and the sensor so that the leaking...
