Description

Head internal circulation isolation oxygen chamber

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a head internal circulation isolation oxygen chamber.

Background

The isolated oxygen cabin with the internal circulation of the head belongs to a passive two-class medical apparatus and is suitable for isolated respiration of patients infected by emergent public health events, particularly pneumonia caused by epidemic situations such as novel coronavirus (including suspected infected patients). It is proved that: the novel coronavirus pneumonia or other similar pneumonia can cause lung injury of a patient, passively increase oxygen inhalation amount of human lungs, and play a role in forced oxygen supplementation of human bodies, so that the aims of improving blood oxygen concentration, enhancing immunity of human bodies and recovering physical strength are fulfilled; the micro high pressure oxygen helps to discharge toxic substances in the human body out of the human body, and plays an extremely important role in the intake of protein and carbohydrate which are necessary for human life. In addition, the head internal circulation isolation oxygen chamber can prevent the gas exhaled by the patient from exchanging with the outside, thereby being beneficial to preventing cross infection.

Technical information relating to the oxygen isolation chamber is found in published chinese patent documents, such as CN202376582U (infant oxygen inhalation device for medical oxygen chamber), CN105919754A (soft oxygen chamber for self-adjusting chamber), and CN208942672U (hyperbaric oxygen chamber), etc., but these patent proposals are not limited to the above-mentioned ones.

CN204017084U recommends "oxygen inhalation mask for high pressure liquid oxygen chamber", which is to arrange two mesh enclosures woven by elastic material in the oxygen inhalation mask, and arrange water-absorbing cotton swabs in the mesh enclosures, so as to ensure the dryness inside the oxygen inhalation mask by virtue of the water absorption of the water-absorbing cotton swabs; CN202314830U provides an "oxygen inhalation mask in hyperbaric oxygen chamber", which is a hood-shaped hood body provided with an oxygen discharge tube and an oxygen supply tube, the oxygen discharge tube is communicated with the oxygen discharge pipeline of the hyperbaric oxygen chamber, the oxygen supply tube is communicated with the oxygen supply pipeline of the hyperbaric oxygen chamber, the oxygen supply tube is provided with an oxygen supply flowmeter and a pressure gauge on the pipeline, the top of the hood body is provided with a safety valve, and the lower edge of the hood body is sealed with the neck of the human body by a flexible sealing element positioned on the lower edge of the hood body in the use state; CN206391334U discloses a safe oxygen inhalation hood of a hyperbaric oxygen chamber, the structure and the use mode of the patent are basically similar to the CN202314830U, and the like. The three patents do not have the unique technical effects, but the requirement of simple isolation oxygen supply cannot be met because the gas exhaled by the patient diffuses to the outside due to the fact that the three patents do not have the internal circulation function. In view of the foregoing, there is a need for improvement, and the technical solutions described below are made in this context.

The function of the suction adjusting valve 2 is: when the gas circulation filtering inactivation mechanism 3 is in failure, the air suction adjusting valve 2 can be opened to allow the outside air to enter the chamber cavity 11, so as to avoid suffocation accident of the patient.

The applicant needs to state that: if the air circulation treatment chamber 13 and the head-isolated oxygen chamber body 1 form a split structure and are connected by pipelines, the method should be regarded as an equivalent technical means.

The head-isolated oxygen chamber body 1 can be divided into three specifications of large, medium and small sizes according to requirements, and can be respectively represented by L, M and S. The pressure in the cabin cavity 11 is positive pressure in the use state, and the above description shows that the pressure is not directly contacted with the outside, so that the isolation cabin can replace an expensive isolation cabin (which is conventionally called as a medical treatment isolation oxygen cabin) in the category of medical instruments equipped by medical departments, and the isolation cabin has good use convenience, so that the isolation cabin is suitable for transporting suspected or confirmed respiratory tract infectious patients in the isolation state, the infection probability of healthy public is effectively reduced, the further spread of the epidemic situation is avoided, and the isolation cabin has positive significance particularly for the use under the pneumonia epidemic situation infected by the current novel coronavirus.

The aforementioned oxygen source introduction control valve 1331 can regulate the flow rate of oxygen gas from the oxygen source, i.e., the oxygen supply source. Because the novel coronavirus pneumonia patient has the trouble of lung injury, oxygen supply can be adjusted according to needs through the oxygen source control valve, so that the lung of a human body is passively increased in oxygen inhalation amount, and the effect of forced oxygen supplementation is achieved on the human body, thereby increasing the blood oxygen concentration, enhancing the immunity of the human body and recovering physical ability. Meanwhile, the micro high-pressure oxygen introduced by the oxygen source is beneficial to discharging toxic substances in the human body out of the human body, and plays a decisive role in the intake of protein and carbohydrate which are necessary for the human body to maintain life. The gas mixture (aerosol containing carbon dioxide and the like) exhaled from the lung is filtered, adsorbed, dosed and sterilized by the gas circulating filtering and inactivating mechanism 3, and then is pressed into the cabin cavity 11 together with the pure oxygen which is connected with the outside and is not higher than 0.025MPa under the action of the circulating fan, so that the auxiliary effect of extracorporeal circulation is achieved. Meanwhile, since the respiratory gas is not exchanged with the outside, cross-infection can be effectively prevented.

In the case of emergency of non-sudden public health events, the invention can be used as 'micro high pressure oxygen therapy' or 'high pressure oxygen therapy', as an ecological treatment measure, and has good curative effect on enhancing the immune cell capacity by promoting the self-renewal process of the body, or a series of diseases caused by hypoxia and ischemia, as well as certain infectious diseases and autoimmune diseases.
