Abstract
This utility model relates to a kind of adjustable-flow oxygen hood, belongs to medical apparatus technical field.It forms primarily of face shield, adjustable face mask joint, oxygen catheter, oxygen therapy joint, and is linked in sequence successively.Face shield is covered patient's mouth and nose and fixed adjustment is good, can cure by oxygen therapy patient.Adjustable face mask joint and scalable is regulated to send oxygen speed during use.
Description
technical field
This utility model relates to a kind of medical instruments, be specially a kind of possess regulate send oxygen speed, reduce oxygen waste oxygen hood.
Background technology
When patient is as occurred hypoxic conditions or dyspnea over the course for the treatment of, oxygen hood is often used to cure by oxygen therapy for it.Current oxygen hood generally includes an oxygen catheter, one end of oxygen catheter is connected with oxygen supply equipment by oxygen therapy joint, the other end is connected with face shield by face shield joint, during use, oxygen therapy joint connected keeping equipment and open oxygen source valve oxygen supply, face shield covered patient's mouth and nose and adjust fixing, starting oxygen therapy.The patient of face shield oxygen therapy is used usually to be unable to leave the bed clinically, or it is handicapped, some patients often needs sending oxygen speed to regulate or switch according to oneself situation in addition, so a patient of convenience oneself regulates and send the oxygen hood of oxygen speed for raising patient comfort degree, economizes on oxygen, reduces nurse's labor intensity, reduces medical treatment cost and just seem particularly important.
Utility model content
For solving the problem, it is simple that this utility model provides a kind of structure, easy to use, and patient's easy adjustment can be made to send oxygen speed, saves the adjustable joint oxygen oxygen hood of oxygen.
For realizing above-mentioned technical purpose, this utility model realizes by the following technical solutions: a kind of adjustable-flow oxygen hood, be characterised in that it is primarily of face shield (1), adjustable face mask joint (2), oxygen catheter (3), oxygen therapy joint (4) is formed, it is characterized in that: adjustable face mask joint (2) is by upper cover (9), lower cover (12), sealing ring (11) forms, upper cover (9), lower cover (12) is respectively containing two through hole feeding oxygen holes (7) connected, oxygen outlet (6), the upper cover (9) of adjustable face mask joint (2) during use, lower cover (12) relatively rotates, the overlapping area of two through holes or groove changes, the effective area change that oxygen is passed through, thus oxygen speed is sent in change, and adjustable face mask joint (2) goes out oxygen interface (5) higher than passage (10).
Feature 1: the upper cover of adjustable face mask joint with lower cover contact surface comprises respectively two through holes or groove docked---feeding oxygen hole and oxygen outlet, when upper and lower cover relatively rotates, the overlapping area of two through holes or groove changes, the effective area change that oxygen is passed through, thus oxygen speed is sent in change.Wherein, feeding oxygen hole and oxygen outlet can be the geometric figure (as rectangle, circle etc.) of rule respectively, also can be irregular geometric figure (as around upper and lower covers central shaft, the figure of diametric(al) area gradual change, as accompanying drawings five)
Feature 2: different from face shield joint common on market, what adjustable face mask joint comprised go out oxygen interface and passage are not at grade, go out oxygen interface higher than passage, closer to patient's nasal cavity, carry out in oxygen therapy process, during patient breaths, go out oxygen interface and go out and first bear vacuum suction, oxygen is by patient's sucking-off, and passage supplements air in time; As the patient exhales, owing to going out oxygen interface closer to patient's nasal cavity, first bear comparatively hyperbar, the oxygen in oxygen catheter compresses temporary in face shield joint, the timely aerofluxus equilibrium air pressure of passage.Improve oxygen utilization rate with this, enter the oxygen that oxygen interface also can be avoided cross-ventilation band between passage to come into oxygen interface sending higher than the design of passage in addition, reduce oxygen and run off.
This utility model has following beneficial effect:
The lower cover of knob face shield joint gently, changes the effective area that oxygen is passed through, and regulates and send oxygen speed, and its structure is simple, easy to use, facilitates patient oneself to regulate, and improves comfort level, alleviates nurse's labor intensity, have significant practicality.
Carry out in oxygen therapy process, go out the design of oxygen interface higher than passage, improve oxygen utilization rate, reduce waste of oxygen when curing by oxygen therapy, its structure is simple, easy to use, has significant practicality.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2, accompanying drawing 3 are adjustable face mask joint design schematic diagram.
Accompanying drawing 4 is adjustable face mask joint operating diagram.
Accompanying drawing 5 is the example schematic of the irregular through hole of upper and lower covers.
In accompanying drawing: face shield (1), adjustable face mask joint (2), oxygen catheter (3), oxygen therapy joint (4), go out oxygen joint (5), oxygen outlet (6), feeding oxygen hole (7), enter oxygen joint (8), passage (10), upper cover (9), lower cover (12), sealing ring (11).
Detailed description of the invention
[0008] referring to shown in accompanying drawing, a kind of adjustable oxygen hood, comprise face shield (1), adjustable face mask joint (2), oxygen catheter (3), oxygen therapy joint (4), face shield (1) covers patient's mouth and nose, and be fixed on patient facial region, oxygen therapy joint (4) is for being connected with oxygen supply equipment, and each parts are in turn connected to form an oxygen path, cure by oxygen therapy for patient.Wherein adjustable face mask joint (2) is made up of upper cover (9), lower cover (12), sealing ring (11), includes oxygen joint (5), oxygen outlet (6), feeding oxygen hole (7), enters oxygen joint (8), passage (10).
It is characterized in that: during use, make upper cover (9) and lower cover (12) relatively rotate, oxygen outlet (6) and feeding oxygen hole (7) overlapping area are changed, the effective area change that oxygen is passed through, thus oxygen speed is sent in change.
In addition, go out the position of position higher than passage (10) of giving vent to anger of oxygen joint (5), closer to patient's nasal cavity, carry out in oxygen therapy process, during patient breaths, go out oxygen joint (5) place and first bear vacuum suction, the oxygen in oxygen catheter (3) is by the quick sucking-off of patient, and passage (10) supplements air in time; As the patient exhales, go out oxygen interface (5) and go out closer to patient's nasal cavity, first bear comparatively hyperbar, the oxygen in oxygen catheter (3) is temporary in in-passage pressure contracting, and passage (10) is aerofluxus equilibrium air pressure in time.Improve oxygen utilization rate with this, go out oxygen interface (5) in addition and cross-ventilation between passage (10) also can be avoided to take away the oxygen of oxygen uptake mouth outflow higher than the design of passage (10), reduce oxygen and run off.The operating diagram of adjustable face mask joint refers to accompanying drawing 4.
Claims (2)
1. an adjustable-flow oxygen hood, it is by face shield (1), adjustable face mask joint (2), oxygen catheter (3), oxygen therapy joint (4) is formed, it is characterized in that: adjustable face mask joint (2) is by upper cover (9), lower cover (12), sealing ring (11) forms, upper cover (9), lower cover (12) is respectively containing two through hole feeding oxygen holes (7) connected, oxygen outlet (6), the upper cover (9) of adjustable face mask joint (2) during use, lower cover (12) relatively rotates, the overlapping area of two through holes or groove changes, the effective area change that oxygen is passed through, thus oxygen speed is sent in change, and adjustable face mask joint (2) goes out oxygen interface (5) higher than passage (10).
2. a kind of adjustable-flow oxygen hood as claimed in claim 1, is characterized in that: described upper cover (9), lower cover (12) are respectively containing two grooves connected.
