Description
Technical Field
The utility model relates to a dust cap technical field especially relates to an oxygen flow meter dust cap.
Background
In order to prevent hospital infection, the dustproof caps of the oxygen flow meter and the aspirator flow meter used in the hospital are all self-made by medical staff by gauze, and the dustproof caps have several disadvantages: firstly, some department gauze is very used as a medical article, and the gauze pieces are troublesome to tie and easy to cause waste; secondly, the gauze cap is easy to fall off; thirdly, the gauze cap is not easy to be sterilized and reused; fourthly, the gauze cap has unattractive appearance.
Current oxygen flow meter dust cap is like utility model patent "a flow meter dust cap" of application number "CN 201921745999.7 in, the dust cap can be through the spacing ring, stops up the quick plug of oxygen, can not drop, but most of dust caps all have its matched with plug, if the dust cap is lost carelessly, can be not good because of incompatible and dustproof effect with other dust caps, and, after the dust cap takes off, inside exposes in the air, can make inside entering dust cap such as dust, can not reach good dustproof effect.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is anticipated to provide an oxygen flow meter dustproof cap to solve current dustproof cap commonality not high, when not using, the problem of dust is easily advanced to dustproof cap inside moreover.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides an oxygen flow meter dust cap, includes the oxygen humidifying bottle, oxygen humidifying bottle circumference outer wall is equipped with gaseous quick plug, the outside cover of gaseous quick plug is equipped with dust cap, a dust cap front portion fixedly connected with elastic line, the free pot head of elastic line is located on the circumference outer wall of flowmeter, the inside foraminiferous rubber buffer in middle part that is equipped with of right-hand member of dust cap, the right-hand member outside of dust cap is equipped with an elastic webbing, the free end fixedly connected with enclosing cover of elastic webbing.
Adopt this technical scheme, when needs use the oxygen humidifying bottle, pull out the dustproof cap, cover the right-hand member of dustproof cap with the enclosing cover, to the inside protection of preventing dust of dustproof cap, later when no longer using the oxygen humidifying bottle, open the enclosing cover, establish the dustproof cap cover on gaseous quick plug, when the plug inserts, can extrude the rubber buffer, make the rubber buffer middle part outwards expand and hug closely the plug, reach good dustproof effect, and because the rubber buffer has good elasticity with the dustproof cap, can be applicable to the plug of different diameters and shape.
Preferably, two limiting rings are arranged on the inner side of the middle part of the dustproof cap.
The limiting ring can be sleeved on the quick gas plug at the dustproof cap to limit the self-sliding relative to the plug and prevent the dustproof cap from falling off.
Preferably, the outer side of the dustproof cap is provided with anti-skid lines.
The anti-slip lines can facilitate the dust cap to be sleeved on the gas quick plug.
Preferably, the dustproof cap is made of elastic silica gel materials, and the outer cover is made of hard plastic materials.
The elastic silica gel material can enable the dustproof cap to be better adapted to plugs with different shapes, the outer cover is made of hard plastics and can be sealed when the dustproof cap is not used, and dust is prevented from entering the interior of the dustproof cap.
Drawings
Fig. 1 is a schematic view of an overall structure provided by an embodiment of the present invention;
fig. 2 is a schematic sectional view of a dust cap according to an embodiment of the present invention;
fig. 3 is a schematic cross-sectional view of a dust cap according to an embodiment of the present invention in a use state.
Detailed Description
The invention will be described in further detail with reference to the following drawings and embodiments:
reference numerals in the drawings of the specification include: the oxygen humidifying bottle comprises an oxygen humidifying bottle 1, a dustproof cap 2, an elastic line 3, a limiting ring 4, a rubber plug 5, an elastic belt 6, an outer cover 7 and a gas quick plug 8.
As shown in fig. 1 to 3, a dust cap for an oxygen flow meter comprises an oxygen humidification bottle 1, a gas quick plug 8 is arranged on the outer wall of the circumference of the oxygen humidification bottle 1, a dust cap 2 made of elastic silica gel material is sleeved on the outer side of the gas quick plug 8, two limiting rings 4 are arranged on the inner side of the middle part of the dust cap 2, a rubber plug 5 with a hole in the middle part is arranged inside the right end of the dust cap 2, an elastic belt 6 is arranged on the outer side of the right end of the dust cap 2, and a hard plastic outer cover 7 is fixedly connected to the free end of the elastic belt 6; an elastic line 3 is fixed at the front part of the dustproof cap 2, and the other end of the elastic line 3 is sleeved on the circumferential outer wall of the flowmeter.
The specific implementation process is as follows:
when needing to use oxygen humidifying bottle 1, pull out dustproof cap 2, cover the right-hand member opening of dustproof cap 2 with enclosing cover 7, 2 inside dustproof protections of dustproof cap, hang under the effect of elastic line 3 on oxygen humidifying bottle 1, later when no longer using oxygen humidifying bottle 1, open enclosing cover 7, hold between the fingers dustproof cap 2 with the hand and establish dustproof cap 2 cover on gaseous quick plug 8, when the plug is inserted, can extrude rubber buffer 5, make rubber buffer 5 middle part outwards expand and hug closely the plug, reach good dustproof effect, and because rubber buffer 5 and dustproof cap 2 have good elasticity, can be applicable to the plug of different diameters and shape, and simultaneously, 2 middle part inboards of dustproof cap are equipped with spacing ring 4, can prevent better that dustproof cap 2 from droing.
The above description is only an example of the present invention, and the detailed technical solutions and/or characteristics known in the solutions are not described too much here. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
