Description

Artificial nose

Technical field

The field of medical instrument technology is the utility model is related to, more particularly, to a kind of artificial nose for assisted respiartion.

Background technology

On clinical medicine, there are some patientss need to be by tracheotomy, Preserving time catheter for tracheostomy.Because of catheter for tracheostomy Directly communicated with air, patient is lost human body in itself by the filtering of nasal cavity, oropharynx to air, heating, the process humidified.

Therefore, humidified, heated, filtered there is an urgent need to a kind of gas that can be sucked to patient, and carried, replace facility Artificial nasal devices.

Utility model content

The purpose of this utility model is to solve the above-mentioned problems and offer one kind is simple in structure, facilitates patient to replace at any time Artificial nose.

One side according to the present utility model, there is provided a kind of artificial nose, including housing and filter house.Shell one end is Air inlet, air inlet are equipped with filter house；The housing other end is tracheae connector, and tracheae connector connects tracheostomy cannula mouth； Filter house is formed by filter core winding, and filter core is equipped with plane layer and flex layers, and flex layers are in wavy, bending after filter core winding Multiple through holes are formed between layer and plane layer.At least one groove and protrusion are equipped with the inside of air inlet.

In some embodiments, be equipped with catch at air inlet, catch is equipped with multiple holes, the hole on catch can in advance every The dust larger from some volumes, has secondary mistake by the cooperation of catch and filter house so as to reach the air sucked to patient The effect of filter.

In some embodiments, catch is made of the material of medical mask.

In some embodiments, tracheae connector is equipped with inner groovy, and packing ring is equipped with inner groovy.Tracheae connector with When artificial respirator connects, the sealing effect of artificial nose and artificial respirator can be increased, be also prevented from artificial nose with manually Respirator is because external force easily comes off.

In some embodiments, a pair of symmetrical groove and protrusion are equipped with the inside of the air inlet.The setting of groove Easy to which filter house is placed into air inlet, after filter house places, protrusion is stuck in the marginal portion of filter house, makes filtering Portion will not easily come off.

Brief description of the drawings

Fig. 1 is the housing of one embodiment of the utility model and the structure diagram of filter house；

Fig. 2 is the structure diagram of the tracheae connector of one embodiment of the utility model；

Fig. 3 is the side schematic view of the filter house of one embodiment of the utility model；

Fig. 4 is the structure diagram of the filter core of one embodiment of the utility model.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1,2,3,4 schematically show a kind of artificial nose according to the present utility model, it includes housing 1 and filter house 2.When it is implemented, housing 1 uses transparent plastic tube body, easy to observe the real-time status of filter house 2.

1 one end of housing is air inlet 10, and air inlet 10 is equipped with filter house 2；1 other end of housing is tracheae connector 11, gas Tube connection ports 11 connect artificial respirator.Specifically, an inner groovy 12 is set at tracheae connector 11, is set in inner groovy 12 One packing ring 13.When tracheae connector 11 is connected with artificial respirator, this connection mode can increase artificial nose with manually exhaling The sealing effect of haustorium, is also prevented from artificial nose with artificial respirator because external force easily comes off.

Filter house 2 is to be wound to form by filter core 21, and filter house 2 is longitudinally inserted into air inlet 10.Filter core 21 is equipped with plane layer 210 With flex layers 211, flex layers 211 are in wavy, and filter core 21 forms multiple between flex layers 211 and plane layer 210 after winding Through hole 22.Wound by filter core 21 equipped with flex layers 211 to strengthen the filter effect of filter house 2, this winding method it is good Place is can to make to contact with each layer filter core 21 as far as possible by the air of filter house 2, so as to reduce the pollution of air, will not be caused Ventilation is not smooth.

The inner side of air inlet 10 is equipped with least one groove 101 and protrusion 102.The setting of groove 101 is easy to put filter house 2 Put in air inlet 10, after filter house 2 places, protrusion 102 is stuck in the marginal portion of filter house 2, makes filter house 2 will not Easily come off.When the utility model is implemented, the inner side of air inlet 10 is equipped with a pair of symmetrical groove 101 and protrusion 102, i.e., The effect above can be played.

When the utility model is embodied, a catch 3 can also be set at air inlet 10, set on catch 3 multiple Hole 30, catch 3 can also be placed by the groove 101 of air inlet 10, and are stuck in below protrusion 102.Hole 30 on catch 3 The larger dust of some volumes can be isolated in advance, by the cooperation of catch 3 and filter house 2 so as to reach the sky sucked to patient Gas has the effect of secondary filter.In order to improve the safe and healthy property of the utility model, catch 3 can use medical mask Material is made.Thus, sufferer can instill some distilled water, by filter house on filter house 2 in advance before using artificial nose After 2 moistenings, the humidity by 2 air of filter house can be increased, be conducive to the recovery of sufferer.

When using the utility model, tracheae connector 11 is connected with artificial respirator, artificial nose can start to work, The artificial nose is small much for the prior art, and passes through inner groovy 12 at tracheae connector 11 and packing ring 13 Setting, can both increase the sealing effect of artificial nose and artificial respirator, be also prevented from artificial nose and artificial respirator because Easily come off for external force.What catch 3 and filter core 21 can more renew at any time, the clean degree of increase sufferer suction air is more When changing, it is only necessary to inject in air inlet 10, firmly press from both sides out catch 3 and filter core 21, Zhi Houzai from groove 101 with instrument New filter core 21 and catch 3 are placed into air inlet 10, is stuck at protrusion 102, that is, completes filter core 21 and catch 3 more Change.

A kind of artificial nose provided by the utility model, its is simple in structure, small, good permeability, with artificial respirator Connection sealing can be good, not easily to fall off；And carry, replace facility.

The above is only the preferred embodiment of the utility model, it is noted that to those skilled in the art, not On the premise of departing from the utility model creation design, some similar modification and improvement can also be made, these also should be regarded as this Within the protection domain of utility model.
