Description

Technical Field

[0001] The utility model relates to the technical field of cardiovascular dilation assistants, and particularly relates to an anti-slip cardiovascular dilation assistant. Background Technique

[0002] A blood vessel dilator is a medical device mainly used for dilating blood vessels to assist doctors in performing endovascular treatments. A blood vessel dilator usually consists of a catheter and a dilation balloon. The catheter is a flexible tube that is inserted into the body, and the dilation balloon of the catheter is used to expand the narrowed blood vessel for endovascular operations such as interventional therapy and angiography. According to different usage purposes and positions, there are various types and specifications of blood vessel dilators. The use of blood vessel dilators can avoid open surgery, reduce the pain and recovery time of patients, and at the same time has a high success rate and safety, becoming one of the indispensable important devices in modern endovascular treatments. Blood vessel dilators are widely used in the fields of cardiovascular diseases, neurovascular diseases, renal vascular diseases, etc., and have a positive impact on the treatment effect and quality of life of patients.

[0003] For example, an anti-slip cardiovascular dilation assistant disclosed in the authorized publication number CN209253052U includes a groove, a boss, a plastic box, and a water-absorbing sponge. The groove is opened at the left edge of the lower end surface of the triple three-way body. The boss is fixed in the groove, and the left end of the boss is fixed at the lower edge of the right end surface of the plastic box. The right end surface of the plastic box is attached to the lower side of the left end surface of the triple three-way body. The water-absorbing sponge is arranged inside the plastic box. Although it solves the problem that the original anti-slip cardiovascular dilation assistant has no blood absorption function, and the small amount of blood leaked at the joint when connecting the puncture needle catheter and the puncture needle connector directly flows onto the operating table, making it troublesome to clean the operating table, the anti-slip effect of the utility model is good, it is convenient to absorb blood, the operation is simple, and the practicability is strong.
