However, due to the urgency of the situation, the operating time of the doctor is not long. Most doctors often cannot control the force because they are too urgent, so that they will seriously scratch the patient's blood vessel wall while trying to puncture the airbag, which will cause great harm to the patient's body. Large, and some inexperienced doctors can't puncture the balloon in the best time to make the balloon return successfully, which requires high operating skills for doctors and increases the risk of patients. Therefore, we need a simple and quick method Piercing the sheath of the balloon

Embodiment Construction
[0014] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0015] Please refer to figure 1 , the present invention provides a sheath that can pierce the balloon 4, the sheath is sleeved on the outside of the balloon 4, the top of the balloon 4 is provided with a balloon 41, the sheath includes a tube body 1, a tube tip 2 and a soluble The drug film 3, the tube tip 2 used to puncture the airbag 41 is located at the end of the tube body 1, and the soluble drug film 3 is fixedly wrapped on the outside of the tube tip 2.
[0016] Before use, the soluble drug film 3 is fixed and wrapped on the outside of the tube tip 2. When the sheath tube is inserted into the inner wall of the patient's blood vessel, it will have a certain expansion effect on the blood vessel. The blood vessel wall is easily scratched and damaged. The tip 2 is ...

The invention provides a sheath that can pierce a balloon. The sheath is sleeved on the outside of the balloon. The top of the balloon is provided with an air bag. The sheath includes a tube body, a tube tip and a soluble drug film for piercing The tube tip of the balloon breaker is located at the end of the tube body, and the soluble drug film is fixedly wrapped on the outside of the tube tip. The present invention can puncture the airbag on the balloon when the balloon cannot be hugged back, so that the balloon can be taken out smoothly, and it can not only prevent the doctor from inserting the sharp guide wire into the blood vessel of the patient by subtracting the airbag at the top of the balloon When puncturing the airbag causes severe damage to the patient's blood vessels, the operation is simpler and time-saving. No matter in terms of difficulty of operation, time-consuming operation or safety of the patient, the effect has been significantly improved.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a sheath tube that can pierce a balloon. Background technique [0002] When doing heart stent surgery or puncture surgery, sheaths and balloons are used. Generally, the sheath is inserted into the patient's blood vessel along the guide wire that acts as a track, and then the balloon is inserted along the sheath. After the patient's blood vessel, the air bag on the balloon stretches out the sheath tube and reaches a suitable position, it is connected to the air gun, and the balloon is inflated into the air bag through the ventilation pipeline and the air gun, so as to stretch the blood vessel and fix it. After the balloon is used, it is necessary to use an air gun to pump air outwards, so that the balloon is hugged back, retracted on the catheter wall of the balloon, and then withdrawn from the patient's body along the sheath. The most common cause of injury is discount, which ...
