The utility model sets the simulation skin, the simulation artery, the liquid pump and the liquid storage tank, the teaching mould mainly adopts the simulation material to simulate the artery of a patient, can show the relation between the inner core and the outer sleeve of the radial artery puncture needle, enables a medical student to better simulate the training operation, and better shows how the puncture needle can be placed into the artery when reaching the space position after penetrating the artery, otherwise, the puncture needle can not be placed into the artery when understanding what unfavorable space position, and how to avoid the puncture needle, so that the student can timely find the own operation error, and the medical worker can timely correct the operation error.
Description
Technical Field
The utility model relates to the technical field of puncture catheterization teaching, in particular to a radial artery puncture catheterization teaching mould.
Background
The radial artery puncture catheter is a relatively common operation in clinic at present, is favorable for continuously monitoring blood pressure, drawing blood and measuring blood gas, and adding electrolytes, and greatly improves the control on vital signs of patients. However, due to the thin anatomical structure, the puncture difficulty is obviously increased particularly when the radial artery pulsation is weak, the pain of a patient is increased by puncturing for many times, radial artery spasm is also caused, and the clinical puncture is also more difficult. Therefore, the medical staff needs to exercise repeatedly to grasp the technique, but the practical operation chance is limited, and many novices cannot understand the relationship between the inner core and the outer cannula of the radial artery puncture needle at first, and cannot understand how the puncture needle can be placed in the puncture needle outer cannula when the puncture needle is inserted to the space position after the artery.
The prior art has the following problems:
at present, no model which can be better used for radial artery puncture catheterization teaching is available, so that explanation demonstration teaching can be rapidly performed on a new student.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a radial artery puncture catheterization teaching model, which solves the problem that no teaching model which can be better used for radial artery puncture catheterization is available at present.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a pipe teaching mould is put in radial artery puncture, includes emulation skin, the inside of emulation skin is provided with emulation artery, one side of emulation skin is provided with the liquid pump that is connected with the emulation artery, one side of liquid pump is provided with the liquid reserve tank, the upper end of liquid reserve tank is provided with the operation panel, the outside of emulation artery is provided with the pjncture needle outer tube, the inside of pjncture needle outer tube is provided with the pjncture needle inner core.
As a preferable technical solution of the present invention, the artificial artery is mainly divided into four artery units, the four artery units have different inner diameters, and the artery units are distributed in the artificial skin in an oblique straight line.
As a preferred technical scheme of the utility model, the puncture needle inner core is positioned inside the puncture needle outer sleeve, and the puncture needle inner core exceeds the puncture needle outer sleeve for a certain distance.
Compared with the prior art, the utility model provides a radial artery puncture catheterization teaching mould, which has the following beneficial effects:
1. this pipe teaching mould is put in radial artery puncture is through setting up emulation skin, emulation artery, liquid pump and liquid reserve tank, and this teaching mould is mainly through adopting emulation material simulation patient's artery, and medical personnel's accessible carries out the simulation training with puncture needle insertion emulation artery, can demonstrate the relation of radial artery puncture needle inner core and outer tube, makes the simulation training operation that carries on that medical personnel can be better, has improved the training effect.
2. This pipe teaching mould is put in radial artery puncture is through setting up emulation artery, pjncture needle outer tube and pjncture needle inner core, this teaching mould demonstrates the pjncture needle better and wears the artery after, when reaching what kind of spatial position, can put into pjncture needle outer tube to the artery in, otherwise, can't put into when understanding what kind of unfavorable spatial position, should how to go to avoid, can in time make the student discover the misoperation of oneself, the medical personnel's of being convenient for timely correction, can also simulate different artery puncture environment simultaneously, the suitability of teaching mould has been improved.
Drawings
FIG. 1 is a schematic view of a teaching mold according to the present invention;
fig. 2 is a schematic structural view showing three cases of insertion of the puncture needle into an artery.
In the figure: 1. simulating skin; 2. simulating an artery; 3. a liquid pump; 4. a liquid storage tank; 5. an operation panel; 6. a puncture needle outer sleeve; 7. an inner core of the puncture needle.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, in this embodiment: the utility model provides a pipe teaching mould is put in radial artery puncture, including emulation skin 1, the inside of emulation skin 1 is provided with emulation artery 2 for training puncture and putting the pipe training and use, one side of emulation skin 1 is provided with liquid pump 3 that is connected with emulation artery 2, a flow for driving inside liquid, the simulation blood flows, one side of liquid pump 3 is provided with liquid reserve tank 4, the upper end of liquid reserve tank 4 is provided with operation panel 5, the outside of emulation artery 2 is provided with pjncture needle outer tube 6, the inside of pjncture needle outer tube 6 is provided with pjncture needle inner core 7.
In the embodiment, the simulated artery 2 is mainly divided into four artery units, the inner diameters of the four artery units are different, and the artery units are distributed in the simulated skin 1 in an inclined straight line, so that the simulation of different artery conditions by the mold is realized, and the training interest of medical care personnel is improved; the puncture needle inner core 7 is positioned inside the puncture needle outer sleeve 6, and the puncture needle inner core 7 exceeds the puncture needle outer sleeve 6 for a certain distance, so that the puncture tube placement training is convenient to use.
