Abstract

The invention belongs to the field of medical education, and in particular relates to a novel medical teaching simulation syringe. A medical teaching simulation syringe, comprising an empty barrel, a piston inserted into the empty barrel, a piston shaft, and a piston handle, the nipple of the empty barrel is sealed, the piston is a hollow pipe filled with liquid, and the front end of the hollow pipe is There is an opening in the center. The piston of the present invention is a hollow pipeline filled with liquid. When the piston is pulled, the liquid in the hollow pipeline is gradually sucked into the hollow tube by negative pressure; The liquid gradually decreases; it not only achieves the purpose of simulated injection, but also avoids the damage of the model caused by the liquid being discharged into the human body model, and also greatly saves the time for the liquid medicine and the operator to draw the medicine liquid.

Description

A medical teaching simulation syringe

technical field

The invention belongs to the field of medical education, and in particular relates to a novel medical teaching simulation syringe.

Background technique

When medical students practice injection, they usually operate on the human simulation model filled with sponge. During injection, the liquid medicine will be injected into the sponge inside the model. After long-term injection, the human model is easy to rot and break. At the same time, the liquid medicine in the syringe needs to be sucked again after injection, which wastes the time of the liquid medicine and the operator.

Contents of the invention

In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a medical teaching simulation syringe with simple structure and easy to use.

A medical teaching simulation syringe, comprising an empty barrel, a piston inserted into the empty barrel, a piston shaft, and a piston handle, the nipple of the empty barrel is sealed, the piston is a hollow pipe filled with liquid, and the front end of the hollow pipe is There is an opening in the center.

Preferably, the teat end of the hollow barrel is sealed by a sealing member.

Preferably, it also includes a needle mounted on the empty barrel.

More preferably, the sealing member is made of PE or PP.

Preferably, the central opening at the front end of the hollow pipe is a circular hole with a diameter of 1mm.

More preferably, the piston is made of opaque material.

In addition, the invention also provides an injection simulation system.

An injection simulation system including a medical teaching simulation syringe and a mannequin for injection practice, a medical teaching simulation syringe including an empty barrel, a piston inserted into the empty barrel, a piston shaft and a piston handle, the nipple of the empty barrel seal, the piston is a hollow pipe filled with liquid, and the center of the front end of the hollow pipe is provided with an opening.

Preferably, the teat end of the hollow barrel is sealed by a sealing member.

Preferably, it also includes a needle mounted on the empty barrel.

More preferably, the sealing member is made of PE or PP.

Preferably, the central opening at the front end of the hollow pipe is a circular hole with a diameter of 1mm.

More preferably, the piston is made of opaque material.

Preferably, the human body model is provided with a fluorescent area at the injection site.

The piston of the present invention is a hollow pipeline filled with liquid. When the piston is pulled, the liquid in the hollow pipeline is gradually sucked into the hollow tube by negative pressure; The liquid gradually decreases; it not only achieves the purpose of simulated injection, but also avoids the damage of the model caused by the liquid being discharged into the human body model, and also greatly saves the time for the liquid medicine and the operator to draw the medicine liquid.

Description of drawings

Fig. 2 is the acupoint injection model of Example 2 of the present invention.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

Example 1

As shown in Figure 1, a medical teaching simulation syringe comprises an empty barrel 1, a piston 2, a piston shaft 3 and a piston handle 3-1 arranged in the empty barrel 1, the empty barrel 1 is provided with a liquid outlet 1-1, and the outlet The liquid port 1-1 is provided with a seal 1-2 (the material of the seal 1-2 is PE or PP), the piston 2 is a hollow pipe 2-2 for holding liquid, and the hollow pipe 2-2 An opening 2-1 is arranged in the center of the front end, and liquid can flow into the hollow cylinder 1 from the hollow pipe 2-2.

The user draws back the piston handle 3-1 when practicing, sucks the liquid in the hollow pipe 2-2 into the hollow tube 1 by negative pressure, and then installs the needle on the hollow tube 1.

When simulating injection, insert the needle into the human body injection model, push the piston handle 3-1, squeeze the liquid into the hollow pipe 2-2 of the piston 2 through pressure, and simulate the process of injecting the liquid medicine into the human body.

When using again, pull the piston handle 3-1 to generate negative pressure in the empty cylinder 1, and with the pulling of the piston 2, the liquid in the hollow pipe 2-2 enters the hollow cylinder 1 through the opening 2-1 on the surface of the piston, simulating The process of pumping medicine into a syringe.

Example 2

As shown in Fig. 2, the injection simulation system composed of the medical teaching simulation syringe described in Example 1 and a human body model, wherein the human body model is an acupoint injection model 100 (the injection model can also be only a model of human upper limbs or lower limbs, or other injection sites Model), the model is the injection area 101 with fluorescent markings on the acupuncture points of the human body. By flashlight irradiation, it is detected whether the injection site is in the fluorescent area 101 to determine whether the injection site is correct.
