First, the model is all made of soft and semi-rigid plastics, the material is firm, durable and light to use Second, each joint of the model can be moved and rotated, and the waist can also be bent 3. This model teaches 24 basic nursing operations: 1, wash your face and bed bath; 2. Oral care; 3. Tracheotomy nursing; 4, oxygen inhalation therapy (nasal obstruction, nasal catheter method “; 5, nasal feeding method; 6. Gastric lavage; 7, intracardiac injection; 8, external chest cardiac resuscitation first aid; 9. Pneumothorax; 10. Thoracic puncture; 11. Liver puncture; 12. Kidney puncture; 13. Abdominal puncture; 14. Bone marrow puncture; 15. Lumbar puncture; 16. Deltoid injection 17. Subcutaneous injection at the lower edge of deltoid muscle; 18, intravenous injection; 19. Venipuncture; 20, intravenous infusion; 21. Venous blood transfusion; 22, female catheterization; 23, hip muscle injection; 24. Breast care; 25. Perineal care; 26, chest compression CPR, Iv. Model operation instructions: 1. All injections in the body, large and small needle blocks at the puncture site are made of soft plastic. After the small needle blocks, a small plastic bottle can be filled with 20CC liquid. 2, the mouth and nose can be used for oxygen, nasal feeding, gastric lavage (the stomach is replaced by a tubular sac) teaching practice. 3, intravenous injection, there is a large needle block in the buttock injection, there is a leather tube (intravenous tube) injection must be injected into the inner cavity of the leather tube, such as a large amount of glucose infusion, the exposed leather tube on the upper buttock should be put into the container to loosen the clamp, and then let the infusion flow out. When teaching blood drawing, inject a small amount of liquid into the tube, and then clamp the upper end of the tube 4, injection or puncture, must pay attention to the central part of the needle block 5, subcutaneous and intramuscular injection method is the same as clinical operation, can inject liquid within the cavernous body can absorb water, can also be extracted to squeeze the water dry. Do not use too much force in the operation of the needle, you can gently press the needle block with your finger, and then the needle is good 6, for external thoracic cardiac resuscitation first aid instruction, you can put your hand on 1/3 of the sternum to press, so that the compression area sank 2.5 cm, when you hear the sound in the chest, that is, let go and restore, battery exhaustion can be replaced. 5. If the injection or piercing needle block is damaged for a long time and can be replaced, as long as the waist iron nut body is divided into two sections, you can inspect the inner wall, unscrew the small plastic bottle, and then remove the damaged needle block to the outside for a new one, and then screw on the small plastic bottle, the hip, the police department, the police department needle block is damaged, you can pull it out, and then replace it with a new one. Such large and small needle blocks have spare parts in each model. 6, urinary catheterization and enema teaching, can be inserted into the leather tube only for teaching action (no liquid outflow 7.

Clamp the tubular capsular skin tube outside the rear buttocks during infusion, and release the clamp with infusion.) Eight, after the completion of the practice, check whether the water in the tube sac is drained, and wipe it clean. 9. The assembly method of the caregiver is detailed in the assembly diagram. 10. Use and maintenance of plastic models: This model is made of soft and hard plastics. 1. In order to facilitate operation at the acupuncture site, lubrication powder (i.e., talc powder) can be applied to the used part to help slip agent and cleaned with post-treatment. 2. If the model is stained with ash after use, a little cleaning agent can be used to wipe it gently or a little soapy water can be used to clean the bucuo. 3, the model should be placed in a cool place, not exposed to the sun, and covered with a cover.
