AI Technical Summary

Benefits of technology

This new version has several technical features compared to previous versions. Firstly, there was an improved design by adding a control socket onto the bal lobe instead of just one spotting contact point. Secondly, this modified version had better placement capabilities than older designs such as those made up entirely from plastic or rubber materials. Thirdly, the use of a lightweight polymer material called polyethylene terepthritisate (PET) could make these modifications easier to manufacturers while still maintain their effectiveness over longer periods of usage. Last but most importantly, some embodiments were able to achieve similar results without requiring more expensive equipment like X-ray fluoroscopy machines.

Problems solved by technology

This technical issue addressed in this patented text relates to treating cardiovascular conditions such as plaque buildup that can lead to blocked blood flow due to excessive accumulation over time on inner walls inside blood vessels (stenosis) after angioplasty procedures for patients with suspected acute coronary syndrome who have been treated with drugs like nitroprusside. Balloons made up mostly of plastic tubes were developed at one end to improve their effectiveness while reducing friction between them and the wall being restored. However these methods still leave some areas where there may exist potential hazards if they happen again.

Embodiment 1

[0059] like Figure 1-3 As mentioned above, the present embodiment 1 provides a balloon catheter capable of removing blood spots in coronary arteries, including a control end, a connecting rod end, and a balloon end, and the control end and the balloon end are connected by the connecting rod The two ends of the terminal are connected.

[0060] The control end includes a pressure pump port 1, a control seat 2, and a control push handle 3; the right end of the pressure pump port 1 is fixedly connected to the control seat 2, and the control push handle 3 is installed on the front of the control seat 2.

[0061] The connecting rod end includes a proximal connecting rod 4, an outer rod 5, and an inner rod 7, the right wall of the control seat 2 is fixedly connected with a proximal connecting rod 4, and the right wall of the proximal connecting rod 4 is connected with an outer rod 5, The top of the outer rod 5 is provided with a guide wire opening 6, and the right wall of the outer ro

Embodiment 2

[0067] Similar to Example 1, a balloon catheter capable of removing blood spots in coronary arteries is provided, but a cured coating is provided on the outer surface of the balloon 8 .

Embodiment 3

[0069] Similar to Example 2, a balloon catheter that can remove blood spots in coronary arteries is provided, but the raw materials of the coating include 15 parts of hydrophilic compounds, 3 parts of enhancers, 0.15 parts of photoinitiators, 65 parts of no water ethanol, 15 parts deionized water.

[0070] The hydrophilic compound is a mixture of polyvinylpyrrolidone and sodium hyaluronate in a weight ratio of 8:1. The K value of the polyvinylpyrrolidone is 15-19. It is purchased from Weifang Bomao New Material Co., Ltd., and its model is K17.

Abstract

The invention discloses a balloon catheter capable of removing blood spots of coronary artery blood vessels. The balloon catheter comprises a pressure pump port; a control base is fixedly connected tothe right end of the pressure pump port; a control pushing handle is installed on the front face of the control base; a near-end connecting rod is fixedly connected to the right wall of the control base; an outer rod is connected to the right wall of the near-end connecting rod in a penetrating mode; a guide wire opening is formed in the top of the outer rod; an inner rod is fixedly connected tothe right wall of the outer rod; a balloon is fixedly connected to the right wall of the inner rod; a catheter body is connected to an inner cavity of the balloon in a penetrating mode; an air bag isfixedly connected to the right end of the catheter body; and developing rings are fixedly connected to the two sides of the balloon. A push rod is mounted at the bottom of the catheter body, so that blood spots can be collected into the left side of the air bag due to the expanded air bag, the catheter body can be withdrawn when a guide wire is inserted into the guide wire opening, the blood spotscan be cleaned conveniently, the operation difficulty of medical staff is greatly reduced, and the health of a patient is guaranteed. Besides, a coating is arranged on the surface of the balloon andhas high lubricity and elasticity, so that the friction between the catheter balloon and a blood vessel is reduced in use, the pain of a patient is relieved, the abrasion of the catheter balloon is reduced, and the stability of the catheter balloon in use is improved.
