Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a simulation dummy for infusion practice. Background Art

[0002] Vascular access maintenance mainly refers to picc and port, Picc and infusion port maintenance, and chemotherapy pump maintenance are currently the main means of intravenous treatment, and infusion port puncture requires special prosthesis operation training. Only after passing the assessment and obtaining the qualification can the operation be performed on the patient, so it is necessary to use a simulated dummy for infusion practice.

[0003] Most existing training dummies use disposable infusion sets to perform puncture exercises on simulated human arm blood vessels. However, due to the lack of drainage structure, the infusion set cannot be opened to adjust the speed, which affects the quality of training. Therefore, some people use latex tubes as simulated blood vessels for practice.

[0004] However, most of the training dummies used for intravenous puncture on the market adopt an integral design. After long-term practice, the internal blood vessels are easily ruptured. Once ruptured, it will cause leakage, thus affecting normal use. Since the training dummies adopt an integral design, the internal blood vessels are fixed to the skin, which makes it difficult to replace the ruptured blood vessels, greatly reducing the practicality. Utility Model Content

[0005] The utility model aims to provide a simulation dummy for infusion practice to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simulation dummy for infusion practice, comprising a simulation dummy body, a simulation arm and a cover plate, wherein a simulation head is arranged above the simulation dummy body, simulation arms are symmetrically arranged on the sides of the simulation dummy body, simulation legs are symmetrically arranged below the simulation dummy body, a blood vessel guide groove is arranged on the simulation arm, a simulated blood vessel is arranged in the blood vessel guide groove, a cover plate is arranged above the simulated blood vessel, a simulated skin is arranged on the cover plate, a T-shaped slide groove is arranged on the side of the simulation arm, a fixing block is symmetrically arranged on both sides of the T-shaped slide groove on the side of the cover plate, a limiting slot is opened on the fixing block, a connecting plate is fixed in the middle of the T-shaped slide groove, T-shaped sliders are symmetrically arranged on both sides of the connecting plate, and each A spring is arranged between each T-shaped slider and the connecting plate, and two ends of the spring are respectively connected to the T-shaped slider and the connecting plate. A positioning plate is arranged on the T-shaped slider, and a limiting plug is arranged on the side of the positioning plate close to the fixed block, and the limiting plug is inserted in the limiting slot to fix the cover plate; by pressing the positioning plate toward the direction of the rear connecting plate and withdrawing the limiting plug on the positioning plate from the limiting slot, the restriction of the fixed block can be cancelled, and then the cover plate can be opened to replace the simulated blood vessel inside. When replacing, it is only necessary to pull the original simulated blood vessel out of the blood vessel guide groove, and then lay the new simulated blood vessel in the blood vessel guide groove. Under normal conditions, the simulated blood vessel will lift up the simulated skin to simulate the protruding blood vessels of the human body.

[0007] Preferably, a liquid storage bag is provided at the end of the simulated blood vessel, and the liquid storage bag is used to store liquid.

[0008] Preferably, the side of the cover plate away from the fixing block is hinged to the simulation arm, and the cover plate can be flipped open after the fixing of the cover plate is cancelled.

[0009] Preferably, the simulation dummy body, simulation head, simulation arms, simulation legs and simulation skin are all made of latex plastic material to simulate human skin.

[0010] Preferably, a simulated palm is provided at the end of the simulated arm to simulate a real dummy arm.

[0012] Preferably, the simulation dummy body is provided with acupuncture points according to the distribution of acupuncture points of the human body, so as to facilitate medical staff to understand the acupuncture points.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model presses the positioning plate so that the positioning plate drives the limiting plug block to move. When the limiting plug block on the positioning plate withdraws from the limiting slot, the restriction of the fixed block can be cancelled. Then the cover plate can be opened to replace the simulated blood vessel inside. After the replacement, the cover plate can be closed again. The operation is simple and easy to understand.

A positioning plate 11 is provided on the T-shaped slider 10. A limiting plug 13 is provided on the side of the positioning plate 11 close to the fixed block 7. The limiting plug 13 is inserted in the limiting slot 12 to fix the cover plate 2; by pressing the positioning plate 11 toward the rear connecting plate 8 and withdrawing the limiting plug 13 on the positioning plate 11 from the limiting slot 12, the restriction of the fixed block 7 can be cancelled, and then the cover plate 2 can be opened to replace the internal simulated blood vessel 4. When replacing, it is only necessary to pull the original simulated blood vessel 4 out of the blood vessel guide groove, and then lay the new simulated blood vessel 4 in the blood vessel guide groove. Under normal conditions, the simulated blood vessel 4 will lift the simulated skin 3 to simulate the protruding blood vessels of the human body.
