Description

Simulation thoracocentesis model

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a simulation thoracocentesis model.

Background

Thoracocentesis is the process of puncturing and withdrawing fluid or gas to relieve the pressure of the fluid or gas on the lung or large blood vessels, improve respiratory or circulatory disturbance, and perform thoracocentesis for diagnosing and treating diseases. The conventional operation method is as follows:

1. the patient sits on the backrest chair in a reverse riding way, the upper limbs bend and elbow are crosswise arranged on the backrest, and the forehead is placed on the forearm.

2. Local infiltration anesthesia is performed from the skin to the pleural wall layer by inserting a needle at the upper edge of the next intercostal rib of the puncture point with 2% lidocaine, so as to avoid damaging intercostal blood vessels and nerves.

3. The latex tube is clamped by a chest puncture needle with the size of 16 or 18, the needle seat is connected with the latex tube, and the latex tube is clamped by a vascular clamp. The skin at the puncture site is fixed by an index finger and a middle finger, and the other hand-held chest puncture needle is firstly penetrated under the skin at the puncture site and then slowly penetrated along the upper edge of the rib according to a local infiltration anesthesia path, so that the skin can have a sudden falling feeling when the skin penetrates the parietal pleura. The assistant connects the end of the latex tube with an empty syringe of 50ml (or more), and the liquid can be pumped by loosening the vascular forceps for clamping the latex tube. After the syringe is full, the latex tube must be clamped by the vascular clamp, the syringe must be removed to inject the liquid into the test tube or other container, the latex tube must be connected after the syringe is emptied, and the vascular clamp must be loosened. The cyclic operation is repeated to draw liquid so as to prevent external air from entering the chest.

4. The liquid is withdrawn, the quantity, color, turbidity and the like are recorded in detail, and the sample is reserved for inspection.

5. After the puncture and suction are finished, the latex tube is clamped, the puncture needle is pulled out, the puncture point is pressed for a moment (1-2 min), sterile gauze is covered after local disinfection, and the patient is fixed by adhesive tape to rest in a static lying state.

In the clinical diagnosis and treatment process, thoracocentesis is very often used, but the operation has a certain difficulty, and the operation directly enters the clinic without practice in the learning process, so that the operation is difficult to be performed for a patient. In order to improve the clinical skill operability, high-simulation medical teaching models are generally used for operation learning and practice.
