Abstract

The utility model provides a medical respirator, including face guard body (1), face guard body (1) including the arc face guard that corresponds human nasal part, mouth and lower jaw position, face guard body (1) go up nasal part cover body both sides and open porose (5), clearing hole (5) are connected with oxygen therapy nasal catheter (3), respirator mandibular department position cover body bottom seted up gas outlet (2). The utility model discloses simple structure, convenient to use, through with the high increase of face guard main part to and set up the face guard gas outlet in face guard lower jaw bottom of a matter portion, increase patient's the invalid chamber of ventilating, thereby it inhales CO2 concentration to increase the patient, respiratory alkalosis that prevention and correction were excessively ventilated and is caused.

Description

A kind of medical respiratory masks

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of medical respiratory masks.

Background technology

Medical respiratory masks provides a side that the oxygen of besoin de respirer can be transferred to from storage tank human lung Method, existing medical respiratory masks typically wraps up nose and face (oral cavity nose cup) or whole face (full facepiece mask), Main Function It is for dyspnea, anoxia patient oxygen therapy.But breathing mask gas outlet the most clinically is arranged on face shield both sides or just to exhaling Gas position, the gas of exhalation comparatively fast gets rid of, so existing breathing mask is mainly oxygen therapy effect, and hyperventilation is easily caused certain A little respiratory's alkalosis, it is therefore desirable to a kind of medical respiratory masks, can meet while normally curing by oxygen therapy, prevent and correct by The respiratory alkalosis that hyperventilation causes.

Utility model content

The problem existed for prior art, this utility model is to solve the technology that problems of the prior art use Scheme is as follows:

A kind of medical respiratory masks, including mask body 1, it is characterised in that: described mask body 1 includes corresponding human body The arc face shield of nose, mouth and mandibular location, in described mask body 1, nose cover body both sides have hole 5, by hole 5 even Being connected to cure by oxygen therapy nose conduit 3, described nose conduit 3 is as common oxygen supply nose guide-tube structure, and described breathing mask lower jaw position is covered Gas outlet 2 is offered, gas and extraneous ventilation in face shield bottom body.

On described mask body 1, nose cover body height is more than mouth and lower jaw position cover body height, in breathing mask Form a bigger air storing cavity.

Described mask body 1 nose height is 6cm-6.5cm, higher than common face shield so that face shield and patient facial region it Between the cavity that formed relatively big, make the gas of exhalation stay in a large number in face shield, secondary sucks, and increases ineffective ventilation chamber.

Described mask body 1 both sides are provided with frenulum 4, and frenulum 4 for being preferably fixed on patient facial region by face shield.

This utility model has the advantage that

This utility model provides a kind of medical respiratory masks, and this breathing mask is made up of mask body and nose conduit, logical Cross and mask body height is increased, and face shield gas outlet is arranged on bottom lower mask jaw end, increase the ineffective ventilation of patient Chamber, thus increase patient and suck CO₂Concentration, prevention hyperventilation patient (e.g., during allergic asthma outbreak, hysteria patient etc.) sends out Raw respiratory alkalosis is it can also be used to treat the respiratory alkalosis that a variety of causes causes.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Wherein: 1-mask body, 2-gas outlet, 3-nose conduit, 4-frenulum, 5-hole.

Detailed description of the invention

Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail, as Shown in Fig. 1, a kind of medical respiratory masks, including mask body 1, it is characterised in that: described mask body 1 includes corresponding human body The arc face shield of nose, mouth and mandibular location, in described mask body 1, nose cover body both sides have hole 5, by hole 5 even Be connected to cure by oxygen therapy nose conduit 3, offer gas outlet 2 bottom described breathing mask lower jaw position cover body, in face shield gas with Extraneous ventilation.On described mask body 1, nose cover body height is more than mouth and lower jaw position cover body height, in breathing mask Form a bigger air storing cavity.Described mask body 1 nose height is 6cm-6.5cm, higher than common face shield so that face shield And the cavity formed between patient facial region is relatively big, makes the gas of exhalation stay in a large number in face shield, secondary sucks, and increases invalid logical Air cavity.Described mask body 1 both sides are provided with frenulum 4, and frenulum 4 for being preferably fixed on patient facial region by face shield.

During use, by frenulum 4, face shield being fixed on patient facial region, internal nose conduit 3 fills in patient nostril, nose conduit 3 For oxygen supply, improve patient and suck O₂Concentration, final lifting arterial blood O₂Dividing potential drop；Mask body 1 is for increasing the invalid logical of patient Air cavity, thus increase patient and suck CO₂Concentration, final raising arterial blood CO₂Dividing potential drop, and then prevention hyperventilation patient (e.g., mistake During quick property asthma attack, hysteria patient etc.) there is respiratory alkalosis it can also be used to the respiratory alkali that causes for the treatment of a variety of causes Poisoning.

Protection domain of the present utility model is not limited to the above embodiments, it is clear that those skilled in the art can be right This utility model carries out various change and deformation without deviating from scope and spirit of the present utility model.If these are changed and deformation Belong in the range of this utility model claim and equivalent technologies thereof, intention the most of the present utility model also comprise these change and Including Bian Xing.
