Problems solved by technology

Some of these treatment methods are one-off, that is, they will not be treated for a long time after one-time treatment, but some may need to be treated repeatedly within a certain period of time. For example, in order to inject insulin, diabetic patients usually need Prick a finger or other part of the skin to collect a small amount of blood, measure the blood sugar level at this time, and then determine the amount of insulin that needs to be injected; as another example, some patients may require long-term antibiotic injections or painkiller injections

Embodiment Construction

[0018] The medical device connected in parallel with blood vessels according to the present invention will be explained in more detail below with reference to the accompanying drawings.

[0019] figure 1 It is a basic schematic diagram of the medical device, which includes a hollow cavity 3 and an inflow channel 1 and a bleeding channel 2 respectively connected thereto. The inner diameter of the blood inlet channel 1 and the bleeding channel 2 is smaller than the inner diameter of the hollow cavity 3, the inner diameter of the hollow cavity 3 is smaller than the inner diameter of the blood vessel, the length of the hollow cavity 3 is between 5mm and 150mm, and the inner diameter is between 1mm and 15mm between. As shown in the figure, the blood-inlet channel 1 and the bleeding channel 2 are respectively percutaneously pierced into blood vessels, such as venous vessels. Since the entire device is connected front and back, and the flow of blood has a certain pressure, the blood...

Abstract

The invention discloses a medical apparatus in parallel with vessels, which comprises a hollow cavity, a blood inlet channel running through the hollow cavity and a blood outlet channel running through the hollow cavity, wherein the blood inlet channel is communicated with vessels through a first opening on the vessel wall; and the blood outlet channel is used for being communicated with the vessels through a second opening on the vessel wall.

Description

technical field [0001] The invention relates to a medical device connected in parallel with blood vessels. Background technique [0002] The human vascular system is a closed blood circulation system, which is responsible for transporting the blood pumped by the heart to various tissues and organs throughout the body to meet the various nutrients required by the body's activities. The vascular system is divided into arteries, veins and capillaries. The blood vessels that transport fresh blood away from the heart are arterial blood vessels. The blood pressure in the arteries is high and the flow velocity is fast. Therefore, the walls of the arteries are thick, elastic and contractile. The blood vessels that transport used blood back to the heart are venous blood vessels. Compared with arterial blood vessels of the same level, venous blood vessels have thinner walls, larger lumens, lower blood pressure, and slower blood flow. [0003] Due to various medical needs, it is ofte...
