Abstract
The utility model provides a low-resistance oxygen supply device for a hyperbaric oxygen chamber, which comprises an upper shell and a lower shell. An airflow baffle is arranged between the upper shell and the lower shell, an airflow hole is arranged at the center of the airflow baffle, a lever is hinged on the inner wall of one side, which is opposite to an air inlet hole, of the lower shell, the top end of the lever penetrates through the airflow hole to contact with a metal lining, a groove is arranged at the lower end of the lever, and the top end of a valve stem is fixed in the groove. The valve stem and the lever form a force enlarging mechanism, the airflow baffle prevents airflow from directly impacting a diaphragm, during oxygen uptake of a patient, the lever shifts the valve stem so that a valve is opened, oxygen uptake resistance of the patient is effectively reduced, and the patient does not need to take larger effort during oxygen uptake. The low-resistance oxygen supply device can be conveniently used for weaker patients and children, and has the advantages of low cost, convenience in installation, safety and reliability.
Description
Technical field
This utility model designs a kind of medical apparatus and instruments, especially a kind of lower resistance hyperbaric oxygen chamber oxygen supply.
Background technology
Medical hyperbaric oxygen chamber is a kind of manned pressure vessel, patient the pressurization oxygen cabin internal respiration pure oxygen to reach the purpose of treatment.Oxygen uptake harness in the hyperbaric oxygen chamber generally all is to adopt simple rocker-type oxygen supply; It is necessary normal outside the resistance of body respiratory tract that oxygen therapic patient need overcome autonomous respiration; Also need firmly overcome pulling second depressurized device flexible sheet to the required negative pressure of lower compression rocking bar; Could open the rocking bar valve, gas is got in the lung through face shield.The shortcoming of this harness has certain resistance when being oxygen uptake, for more weak patient of body constitution and child long-time oxygen uptake meeting very tired, also have the motionless situation of inhaling.
Summary of the invention
The purpose of this utility model provides a kind of lower resistance hyperbaric oxygen chamber oxygen supply, the oxygen uptake resistance in the time of can reducing patients accepting oxygen inhalation effectively.
In order to solve the problems of the technologies described above, the technical scheme of this utility model is following: lower resistance hyperbaric oxygen chamber oxygen supply comprises upper shell, lower house; Upper shell inside is provided with pressure-sensitive diaphragm, is provided with the metal liner in the pressure-sensitive diaphragm, and the centre position on upper shell top is equipped with the adjusting bolt; One side of lower house is provided with air inlet, and air inlet is provided with valve outward, and the valve rod of valve stretches in the lower house in air inlet; The bottom of lower house is provided with the gas outlet, it is characterized in that: be provided with blast fence between said upper shell and the lower house, the blast fence center is provided with airflow hole; Be hinged with lever on the relative side inwall of lower house and air inlet; The top of lever is passed airflow hole and is contacted with the metal liner, and the lower end of lever is provided with groove, and the top of valve rod is fixed in this groove.
Beneficial effect:
Use the described lower resistance hyperbaric oxygen chamber of this utility model oxygen supply, formed the enlarger of power through valve rod and lever, the use of blast fence has avoided air-flow directly to impact diaphragm; Stir the purpose that valve rod reaches Open valve through lever during patients accepting oxygen inhalation, can reduce patient's oxygen uptake resistance effectively, needn't use big strength during personnel's oxygen uptake; Being convenient to more weak patient of body constitution and child uses; It has low, easy for installation, the safe and reliable characteristics of cost.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
This utility model lower resistance hyperbaric oxygen chamber oxygen supply as shown in Figure 1 comprises upper shell 7, lower house 8, and upper shell 7 inside are provided with pressure-sensitive diaphragm 6; Be provided with metal liner 5 in the pressure-sensitive diaphragm 6, the centre position on upper shell 7 tops is equipped with regulates bolt 4, and a side of lower house 8 is provided with air inlet 14; Be provided with valve 2 outside the air inlet 1, the valve rod 3 of valve 2 stretches in the lower house 8 in air inlet 14, and the bottom of lower house 8 is provided with gas outlet 11; Be provided with blast fence 13 between said upper shell 7 and the lower house 8; Blast fence 13 centers are provided with airflow hole 12, are hinged with lever 10 through bearing pin 9 on the relative side inwall of lower house 8 and air inlet 1, and the top of lever 10 is passed airflow hole 12 and contacted with metal liner 5; The lower end of lever 10 is provided with groove 14, and the top of valve rod 3 is fixed in the groove 14.
