Embodiment 1

[0012] Example 1. A kind of arterial blood bypass tube whose fixed structure is a balloon

[0013] The present invention is made of silica gel, and the blood diversion tube 1 has an outer diameter of 4mm, a wall thickness of 0.5mm, and a length of 60mm. The balloon 2 is composed of a balloon body 2.1, a balloon tube 2.2 and a one-way valve 2.3. The two balloon bodies are respectively wrapped outside the two ends of the blood diversion tube. The wall part of the blood diversion tube is 20 mm long, the inner diameter of the balloon tube is 2 mm, the free part of the tail is 20 mm long, and the outer diameter is 4 mm.

Embodiment 2

[0015] The blood diversion tube 1 of the present invention has an outer diameter of 5mm and a length of 80mm. The outer diameter of the balloon body after filling is 7mm. The wall part of the balloon tube and the blood diversion tube is 25mm long. Hemostatic film, all the other are with embodiment 1.

Embodiment 3

[0017] The blood diversion tube 1 of the present invention has an outer diameter of 7mm and a length of 150mm. After the balloon is inflated, the outer diameter is 9mm, and a color bar is set longitudinally on the tube wall and marked with a scale. The middle part of the tube wall is covered with a 50mm long self-adhesive hemostatic film, and the wall part of the balloon tube and the blood diversion tube is 30mm long. , all the other are with embodiment 1.

Abstract

The invention relates to the technical field of medical devices, which is an arteri-blood flow diverting pipe with fixed structure and for first aid of limb blood vessel wounds. The invention consists of a blood flow diverting pipe (1) and a fixed structure; pipe tops on both ends of the blood flow diverting pipe are inclined; a color strip with calibration can be arranged longitudinally on the pipe wall of the blood flow diverting pipe (1). A self-sticking blood stopper film can be coated on the pipe wall of the middle section of the blood flow diverting pipe; the fixed structure consists of two saccules (2) or two fixed rings (3); each saccule (2) consists of a saccule body (2.1), a saccule pipe (2.2) and an air supply valve (2.3); the two saccules bodies are respectively wrapped on the pipes on both ends of the blood flow diverting pipe; the fixed rings (3) are pipe wall circular heaves on both ends of the blood flow diverting pipe. The invention has the advantages of simple structure and convenience in use, plays the role of quickly stopping the blood from flowing out so as to ensure blood supply to the limbs through building temporary channels on the blood vessel breakage ends, reduces the risk of limb amputation, and meets the time requirements of diversion or sending for treatment afterwards.

Description

technical field [0001] The invention relates to the technical field of medical devices, and relates to an arterial blood diversion tube with a fixed structure used for limb vascular warfare and trauma first aid. Background technique [0002] Limb vascular trauma is a common trauma in wartime, and it is not uncommon in accidents such as car accidents and industrial injuries. If timely treatment cannot be obtained, such as in wartime, there will often be high amputation rates, many complications, serious pollution, It is easy to cause shock and limb dysfunction, which seriously threatens the life and health of the wounded. This is because the main methods of vascular trauma treatment at home and abroad are hemostasis, ligation and vascular anastomosis. Among them, hemostasis, ligation, etc. are used in field rescue, and it is necessary to race against time. The purpose is to control bleeding and save lives. However, for some important blood vessels such as the carotid artery...
