Embodiment Construction

[0018] Oxygen uptake by the human body (O 2 ) is accomplished by breathing, that is, the human lungs can combine the inhaled oxygen with the hemoglobin in the blood [while releasing carbon dioxide (CO 2 )] become oxyhemoglobin, and oxygen (O 2 ) directly dissolves into the blood through the principle of diffusion, and then transports oxygen (O 2 ) Transport the whole body to supply organs, tissues and cells. Oxygen meter 22 is to utilize the flow process of blood in the extracorporeal circulation circuit to interact with oxygen (O 2 ) in direct contact with oxygen (O 2 ) combined with hemoglobin and oxygen (O 2 ) dissolved in the blood to reach the uptake of oxygen (O 2 )the goal of.

[0019] See attached figure 1 , is the local structure of the extracorporeal circulation pipeline: (that is, the local structure of the extracorporeal circulation pipeline used in the existing blood purification technology) the degassing pot 13 is a closed cavity body in the shape of a rou...

Abstract

The invention relates to the field of medical apparatus and instruments and in particular to a blood purification therapy oxygen supplying instrument. At present, the clinic oxygen supplying modes comprise catheter nasal oxygen inhalation, mask oxygen inhalation, artificial and mechanical ventilation, ultraviolet radiation blood infusion or high pressure oxygen bins, and the like, which are respectively a single oxygen supplying mode, and have a certain limit. The invention aims to provide the blood purification therapy oxygen supplying instrument. The instrument has a structure in which one end of a connection opening A is connected with an electromagnetic valve in serial, and is then divided into two branches, one branch is communicated with an injector through being connected with a pressure sensor in series, and the other branch is connected with the electromagnetic valve, a protective cover and a connecting opening B in series; and one end of a connecting opening C is sequentially connected with the protective cover, the pressure sensor and the electromagnetic valve through an oxygen catheter; and the other end of the electromagnetic valve is divided into two branches, one branch is communicated with the injector, and the other branch is communicated with the atmosphere after being connected with the electromagnetic valve in series. The purpose of the invention is to make up the problem that in the prior art, the blood purification oxygen therapy method of patients has limits, realize oxygen supply by a new path or two paths, improve the oxygen therapy effect, and relieve the hurt to body tissues due to oxygen deficiency.

Description

1. Technical field [0001] The invention relates to a medical device, which is an instrument or device specially used for supplying oxygen to patients in the process of blood purification treatment, that is, an oxygen supply instrument for blood purification treatment. 2. Background technology [0002] Oxygen (O 2 ) is an important substance that cannot be separated from the human body for a moment. When various diseases lead to hypoxia in the body, it will cause cell metabolism disorder, dysfunction and even death. Therefore, oxygen therapy (oxygen therapy for short) is an important means to improve or correct hypoxemia in the body. Patients with chronic renal failure (relying on blood purification therapy for survival, three times a week, 4-8 hours each time) often have hypoxia in varying degrees, and oxygen therapy during blood purification therapy is very common. At present, routine clinical oxygen supply methods include: nasal cannula or face mask oxygen inhalation, a...
