Problems solved by technology

[0005] Aiming at the above-mentioned problems in the prior art, the present invention provides a low-temperature blood vessel protection device, which solves the problem that the existing mechanical thrombectomy method uses a localized area on the skin surface by lowering the temperature of the blood in the blood vessel and displaying the specific temperature of the cooling area. The cold compress cools the blood in the blood vessels, resulting in poor cooling effect. It is impossible to accurately evaluate the cooling effect of the blood in the blood vessels, resulting in the failure to achieve the expected effect of the operation.

Embodiment 1

[0031] Such as Figure 1~6 As shown, the present invention provides a low-temperature blood vessel protection device, which includes a catheter 1 for intervening in blood vessels, and a fluid-filled channel 2 and a fluid-return channel 3 that are independent of each other and extend axially are arranged in the thick wall layer of the catheter 1 and a lateral channel 4; the outer wall of the head end of the catheter 1 is provided with a plurality of interconnected balloons 5, and the liquid filling channel 2 and the liquid return channel 3 are all communicated with the balloon 5; the lateral channel 4 is provided with a catheter for measuring 1. A temperature measuring sensor 6 for internal temperature. The temperature measuring sensor 6 is electrically connected to the external temperature display device. The number of balloons 5 is preferably but not limited to 4, and each balloon 5 is provided with a development mark. The developing marks can be detected by X-rays, so that ...

Embodiment 2

[0034] Such as Figure 1~6 As shown, this embodiment is further limited on the basis of Example 1. As a specific implementation of the liquid-filled channel 2 and the liquid-return channel 3 in the wall thickness layer of the catheter 1, the liquid-filled channel 2 and the adjacent The balloon 5 on the outer wall of the head end of the catheter 1 communicates, and the liquid return channel 3 communicates with the balloon 5 on the outer wall near the tail end of the catheter 1, so that the cooling liquid moves from the balloon 5 on the outer wall near the head end of the catheter 1 to the catheter 1 in turn. The balloon 5 on the outer wall of the tail end is reflowed to ensure that the cooling liquid first reaches the balloon 5 on the outer wall near the head end of the catheter 1; A specific embodiment, the liquid filling channel 2 communicates with the balloon 5 on the outer wall near the end of the catheter 1, and the liquid return channel 3 communicates with the balloon 5 o...

Embodiment 3

[0039] Such as Figure 1~6 As shown, this embodiment is further limited on the basis of implementation 2. The outer wall of the proximal tube body 101 is provided with a stress relief tube section 8, which is a hollow circular platform structure. The outer wall of the small diameter end of the stress release tube section 8 is The diameter is the same as the outer diameter of the distal tube body 102, and the inner wall of the large-diameter end of the stress release tube section 8 is provided with a card slot 9, and the catheter adapter 7 is provided with a buckle 10 that matches the card slot 9, and the large diameter of the stress release tube section 8 The diameter end is connected with the catheter base 7 through the engagement of the slot 9 and the buckle 10 . The stress relief pipe section 8 is used to transition the step on the catheter adapter 7, so that the connection between the catheter adapter 7 and the proximal tube body 101 is smoother, and when the protective de...

Abstract

The invention discloses a low-temperature blood vessel protection device. The low-temperature blood vessel protection device comprises a catheter used for being inserted into a blood vessel, and a liquid filling channel, a liquid return channel and a lateral channel which are independent of one another and extend in the axial direction are formed in a wall thickness layer of the catheter; a plurality of balloons communicated with one another are arranged on the catheter, and the liquid filling channel and the liquid return channel are both communicated with the balloons; and a temperature measuring sensor electrically connected with an external temperature display device is arranged in the lateral channel. The catheter is inserted into the blood vessel, cooling liquid is injected into the liquid filling channel, flows through the balloons and then flows out of the liquid return channel, the blood temperature is reduced through liquid circulation of the liquid filling channel and the liquid return channel, and the blood temperature is reduced; and the temperature measuring sensor is used for measuring the temperature in the catheter in real time, the temperature in the catheter is visually displayed through the external temperature display device, medical staff can visually know the temperature of blood in the blood vessel conveniently, the cooling temperature can be conveniently controlled, the cooling effect of the blood in the blood vessel can be conveniently and accurately evaluated, and the expected effect of an operation is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a low-temperature blood vessel protection device. Background technique [0002] Interventional therapy is a new type of endovascular treatment of diseases, after years of development. Interventional equipment for cardiovascular and cerebrovascular diseases has been rapidly developed and innovated with the development of imaging equipment and interventional technology. [0003] Acute ischemic stroke (acute ischemic stroke, AIS) accounts for about 85% of all strokes, with high morbidity, disability, mortality and recurrence, and the annual death toll reaches 1.5 million in my country alone. For the treatment of patients with acute ischemic occlusion, from arterial thrombolysis, arteriovenous bridging thrombolysis, endovascular angioplasty, to mechanical thrombectomy, the recanalization rate of stenosis and occlusion has been significantly improved compared with before. ...
