Abstract
The utility model relates to a universal oxygen inhalation mask for an ophthalmologic operation. The universal oxygen inhalation mask for the ophthalmologic operation comprises a transparent mask body, an air storage bag, and an oxygen duct, wherein two one-way valves are arranged on the middle portions of two sides of the mask body, an oxygen connector is arranged on the upper portion of the mask body, the gas storage bag is connected with the oxygen connector though a connecting pipe, and a one-way valve is arranged inside the connecting pipe. Besides, a side opening of the oxygen connector is arranged on the side face of the connecting pipe, and the oxygen duct is connected with the side opening of the oxygen connector. An oxygen duct connector is arranged on the head end of the oxygen duct and is in conic shape, the external diameter of the oxygen duct connector is from 15.8 millimeters to 15.5 millimeters, and the inner diameter of the oxygen duct connector is from 4.5 millimeters to 8.5 millimeters. The oxygen duct connector can not only be connected with a humidification bottle or a special connector, but also be connected with an anaesthesia machine screwed pipe. Edges of the lower portion of the transparent mask body successively contact with a tip of a nose, outsides of nostrils, corners of a mouth, and a lower jaw so as to guarantee a certain distance between a transparent mask body position and an eyes position and can effectively avoid the effect to the ophthalmologic operation.
Description
Technical field
This utility model belongs to medical medical instruments field, is specifically related to the universal oxygen absorption mask of a kind of ophthalmologic operation.
Background technology
At present, oxygen absorption mask is widely used clinically, and the oxygen absorption mask in the different operations is also different clinically.Wherein, in ophthalmologic operation, the patient overwhelming majority finishes operation under local anesthesia, generally will suck for the patient provides oxygen in the operation.As use common mask oxygen-inspiration since common face shield edge far from operative region too close to, affect operation technique; As use nasal tube oxygen inhalation, and then be easy to make concentration of oxygen inhalation to descend, cause waste of oxygen.In addition, common oxygen absorption mask is general only to be connected with humidification bottle or particular interface, can't be connected with anaesthetic apparatus screwed pipe.
Summary of the invention
This utility model has overcome deficiency of the prior art, and a kind of universal oxygen absorption mask that is applicable to ophthalmologic operation is provided.The design of face shield integral outer can make the carrying out that does not affect operated eye in oxygen uptake, the design of unidirectional valve can avoid the interior oxygen of face shield excessive, improve the oxygen uptake effect, can make the carbon dioxide of exhalation in transparent cover, flow to the outside simultaneously, improve concentration of oxygen inhalation.
In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions: the universal oxygen absorption mask of ophthalmologic operation, comprise transparent cover, transparent cover two middle side parts are provided with two unidirectional valves, the transparent cover lower edge is provided with the perforation of degree of tightness frenulum, transparent cover top is provided with the oxygen interface, it is characterized in that air storage bag links to each other by a connection tube with the oxygen interface, and connection tube inside is provided with unidirectional valve, the connection tube side is provided with an oxygen interface side opening, oxygen catheter links to each other with oxygen interface side opening, and the oxygen catheter head end is provided with the oxygen catheter interface, and the oxygen catheter interface is conical, its external diameter is 15.8-15.5mm, internal diameter is 4.5-8.5mm, both can be connected with humidification bottle or particular interface, also can be connected with anaesthetic apparatus screwed pipe; Air storage bag links to each other by connection tube with the oxygen interface, and oxygen is introduced into air storage bag by oxygen catheter, and connection tube inside is provided with unidirectional valve, and oxygen enters in the transparent cover by unidirectional valve in the air storage bag; The transparent cover lower edge contacts with nose, the outside, nostril, bicker, lower jaw successively, and transparent cover contacts top section and is provided with a stator with nose, makes the face shield front end can random-shaping, fits tightr with face.
The beneficial effects of the utility model: the configuration design of transparent cover, so that certain distance is arranged between cover body and the eye, can effectively avoid the impact on operated eye; The design of oxygen catheter interface can be connected with multiple catheter interface; Two unidirectional valves of transparent cover top symmetry guarantee that in patient's oxygen uptake oxygen intake can be not excessive, improve the oxygen uptake effect, when the patient exhales, guarantee that the carbon dioxide of breathing out can only flow out from the unidirectional valve of transparent cover both sides; The unidirectional valve of connection tube inside guarantees that oxygen intake can only enter transparent cover from air storage bag, and can effectively stop the carbon dioxide of exhalation to flow in the air storage bag, improves patient's concentration of oxygen inhalation.

1. transparent covers among the figure, 2. unidirectional valve, 3. degree of tightness frenulum perforation, 4. oxygen interface, 5. air storage bag, 6. connection tube, 7. oxygen interface side opening, 8. oxygen catheter, 9. oxygen catheter interface, 10. stator, 11. unidirectional valves.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment this utility model is described in further detail: transparent cover 1 lower edge is designed to successively and nose, the outside, nostril, bicker, the lower jaw contact, make certain distance is arranged between transparent cover 1 and the eye, effectively avoid the impact on operated eye, and use the degree of tightness frenulum to fix, air storage bag 5 is connected with oxygen interface 4 by connection tube 6, oxygen interface side opening 7 is connected with oxygen catheter 8, respirator is connected with oxygen catheter interface 9, the oxygen that sucks at first enters in the air storage bag 5, when the patient is air-breathing, because air storage bag 5 internal pressures are greater than transparent cover 1 internal pressure, this pressure promotes the unidirectional valve 11 in the connection tube 6, make 11 one-tenth open modes of unidirectional valve, oxygen enters in the transparent cover 1, at this moment by unidirectional valve 11, because external pressure is greater than transparent cover 1 internal pressure, the unidirectional valve 2 that is located at transparent cover 1 both sides symmetry is close on the transparent cover 1, is avoided the excessive of oxygen intake, improve the oxygen uptake effect; When the patient exhales, because transparent cover 1 internal pressure is greater than air storage bag 5 internal pressures, this pressure promotes the unidirectional valve 11 in the connection tube 6, make unidirectional valve 11 become closed condition from open mode, the carbon dioxide of breathing out can not flow in the air storage bag 5, guarantee the purity of air storage bag 5 interior oxygen, at this moment, because transparent cover 1 internal pressure is greater than external pressure, the unidirectional valve 2 that is positioned at transparent cover 1 both sides symmetry becomes open mode by closed condition, and the carbon dioxide that the patient is breathed out can only flow out from these two unidirectional valves 2.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that produces does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
