Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Examples
Referring to fig. 1, a simple and easy simulation training device is maintained to PICC pipeline includes: the simulated human body 10 and the simulated pipeline 20 embedded in the simulated human body 10 have the structure of the simulated human body 10 consistent with the anatomical structure of the human body.
One end of the simulated circuit 20 extends from the arm of the simulated human body 10, and is generally referred to as the distal end, where the PICC circuit is maintained, and the nursing staff is required to maintain the PICC, including: changing the transfusion joint, performing pulse type flushing, fixing and the like. The diameter of the puncture at the distal end of the simulated pipeline 20 is the same as the diameter of a natural sinus formed by the human body after the catheter is placed and the skin is expanded (approximately the diameter of the PICC pipeline), so that the condition of the simulated pipeline 20 in the simulated human body 10 blood vessel is highly similar to the condition of the simulated pipeline in the human body blood vessel. The operator can experience the feeling of the PICC pipeline in the blood vessel without any protection device during maintenance, and master the skill and the proper strength of the left-hand lifting PICC catheter, thereby improving the maintenance operation level, effectively avoiding the disconnection caused by improper maintenance, prolonging the service life of the catheter and better serving clinical patients.
The distal end of the simulation pipeline 20 is bifurcated with a basilic vein 21 elbow median vein 22 and a cephalic vein 23, and each simulation vein pipeline is consistent with the actual vein position of a human body, so that an operator can conveniently simulate the PICC pipeline maintenance at different positions.
The other end of the simulation pipeline 20 is communicated with a heart-shaped liquid bag 24, and the heart-shaped liquid bag 24 is positioned inside the simulation human body 10 and is close to the heart. The simulation human body 10 is provided with a slidable visual window 11 corresponding to the heart-shaped liquid bag 24, the visual window 11 is positioned at the 5 th to 7 th thoracic vertebrae horizontal position, so that whether the flushing and sealing tube manipulation of an operator is correct and effective or not is conveniently observed, and whether the pulse positive pressure manipulation is really achieved or not is conveniently observed, and therefore the catheter blockage caused by the backflow of blood to the catheter due to the improper tube sealing manipulation is effectively avoided.
Moreover, the visual window 11 is in sliding fit with the simulated human body 10, and the heart-shaped liquid bag 24 can be opened or closed through the sliding visual window 11, so that when the end part of the simulated pipeline 20 is pulled out due to improper maintenance, the end part of the simulated pipeline 20 can be manually and timely returned to the correct position.
The top of the heart-shaped fluid bag 24 is connected to an inlet tube 25, and the position of the inlet tube 24 is the same as the position 1/3 below the superior vena cava for simulating the great vein in the heart. The simulated tube 20 extends into the interior of the inlet tube 25 and avoids the end of the simulated tube 20 entering directly into the interior of the cardioid bag 24. The size proportion of the ingress pipe 25 relative to the simulation pipeline 20 is larger than that of the superior vena cava and the PICC pipeline, so that the training difficulty of an operator in the remote end operation of the simulation pipeline 20 is larger than the real difficulty, and the PICC pipeline maintenance level can be improved rapidly.
The top of the heart-shaped liquid bag 24 is connected with a photoelectric sensor 29, the sensing area of the photoelectric sensor 29 corresponds to the inlet pipe 25, and the simulated human body 10 is provided with an alarm 28 which is in communication connection with the photoelectric sensor 29. By arranging the photoelectric sensor 29 for detecting the inner area of the inlet pipe 25 in real time, when the end part of the simulation pipeline 10 slides out of the inlet pipe 25 or accidentally enters the heart-shaped liquid bag 24, the photoelectric sensor 29 sends an electric signal to the alarm 28, and the alarm 28 is used for sounding an alarm to warn.
A drain pipe 26 is communicated with the bottom of the heart-shaped liquid bag 24, and the drain pipe 26 penetrates through the simulated human body 10, so that the liquid in the heart-shaped liquid bag 24 can be conveniently drained. The liquid discharge pipe 26 is also detachably connected with a liquid storage mechanism 30, and can be in threaded connection or clamped connection, so that the liquid discharge pipe is convenient to assemble and disassemble. The operator can also conveniently observe the blood drawing condition and clean the liquid entering the heart-shaped liquid bag 24 from the flushing and sealing tube at any time.
The liquid storage mechanism 30 includes: a liquid storage bag 31 communicated with the liquid discharge pipe 26, a liquid stopping clamp 32 connected with the top of the liquid storage bag 31 and a switch valve 33 arranged at the outlet at the bottom of the liquid storage bag 31, wherein the liquid storage bag 31 can be used for collecting the liquid discharged from the heart-shaped liquid bag 24. The liquid stop clip 32 and the switch valve 33 are used for controlling the on-off of the inflow and outflow channels of the liquid storage bag 31.
Referring to fig. 1 and 2, a peristalsis mechanism 40 is further provided inside the simulated human body 10, the peristalsis mechanism 40 including: a driving member 41 providing a power source, a rotating head 42 connected to the driving member 41, a fixing block 43 engaged with the rotating head 42, and a peristaltic switch 44 disposed on the surface of the simulated human body 10. The peristaltic switch 44 is used to control the start and stop and forward and reverse rotation of the driving member 41, so that the driving member 41 starts to rotate and the rotating head 42 is driven to rotate. The four rotary heads 42 are respectively disposed around the driving member 41, and when the driving member 41 rotates, the rotary heads 42 can synchronously rotate along the driving member 41. The fixing block 43 is used for limiting the simulation pipeline 20, and when the rotating head 42 rotates, the side wall of the simulation pipeline 20 is squeezed, so that negative pressure is formed inside the simulation pipeline 20, and the flowing speed of fluid inside the simulation pipeline 20 can be accelerated.
