Description

Prevent pressure damage breathing machine face guard

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a respirator mask capable of preventing pressure damage.

Background

The respirator mask is used as an interface between the respirator and a patient, is in direct contact with the patient, is a tool for assisting the respirator in ventilation, and plays a role in the treatment process. The time of using the breathing machine by a general patient is kept at least for 6-8h, the vertical pressure is increased by long-time pressing of the face mask, the blood flow at the pressed part of the face mask is blocked, so that pressure injury is easy to occur, and the longer the pressing time is, the higher the incidence rate of ulcer caused by the pressure injury is. Retrospective investigation of patients with noninvasive positive airway pressure found that facial pressure injury occurred at 25.49% during use of noninvasive positive airway pressure.

At present, in order to reduce the pressure injury, common solutions relax patients who continuously use noninvasive ventilators for 1 time every 4 hours, or prevent the pressure injury of the nasal face of the noninvasive positive airway pressure patient by using a dressing. However, patients who go up the ventilator are in a serious condition, and need to use the noninvasive ventilator for a long time, some patients need to use the noninvasive ventilator for a plurality of days even after 24 hours each day, and some COPD patients need to wear a mask at home and use a household ventilator frequently even after being discharged. Various pressure-proof dressings which are clinically adopted at present are pasted on the face, a thin layer of soluble transparent adhesive tape is generally pasted on one face, which is in contact with the skin, of the dressing to fix the face paste to be immobile, certain stimulation is caused to the face after the pasting time is too long, discomfort is increased, the dressing needs to be frequently replaced, the cost of a patient is increased, and the dressing can not avoid pressure injury, which refers to local skin or subcutaneous soft tissue injury and generally occurs at a bone bulge or a position related to medical equipment. Is a lesion of the intact or open ulceration of the skin and may be associated with pain. Medical device-related stress injuries, the nature of the injury site is generally consistent with the nature of the medical device. The skin of the patient is wounded or even infected due to the related pressure injury of the medical apparatus generated by the mask, so that the patient cannot continuously wear the respirator mask, and the pain and medical cost of the patient are increased (the wound in the technical scheme refers to but is not limited to the wound caused by the pressure injury).

In modern medicine, there is a great need for a good mask that fully combines the characteristics of human facial engineering to ensure comfortable wearing and good sealing, thereby improving the curative effect and ensuring the accurate operation of various functions of a noninvasive ventilator, and particularly, a mask for a ventilator that wraps the wound of a patient to prevent pressure injury or protect the wound of the patient who has suffered pressure injury, and prevents the wound from being squeezed to deepen ulcer and infection is provided.

Disclosure of Invention

In order to solve the above problems, the present invention provides a respirator mask for preventing pressure injury, or protecting the wound of a patient who has suffered pressure injury, wrapping the wound of the patient to avoid the wound being pressed to deepen ulcer and infection.

In order to achieve the purpose, the technical scheme of the invention is as follows: prevent pressure nature damage breathing machine face guard, including the face guard portion that covers patient's face and the oxygen therapy machine that supplies oxygen therapy, it has the air duct to communicate between face guard portion and the oxygen therapy machine, face guard portion includes chin, pressure nose portion and oral cavity portion, the flank and the bridge of the nose end of pressing the nose portion all have the mobius loop structure, the surface of mobius loop is equipped with arc recess, and just mobius loop both ends bond with face guard portion, and the inside lax of mobius loop.

Furthermore, the surface of the air duct is provided with a notch, a sliding device is arranged in the notch and comprises a rotating pin, a connecting rod and a push plate covering the surface of the notch, the connecting rod is positioned at the bottom of the push plate, the bottom of the connecting rod is provided with a round hole, and independent rotating pins are respectively connected between any round hole and the air duct.

Further, the cross section of connecting rod is "T" font, and the connecting rod includes horizontal pole and montant, the horizontal pole bearing is in the push pedal, and horizontal pole and layer board fixed connection, the side of horizontal pole has the notch, notch and the breach department adaptation of air duct are connected.

Furthermore, a torsion spring is wound between the vertical rod and the rotating pin.

Further, the chin is convex outward, a cavity is formed between the chin and the face of the patient, a transition arc which is concave back is arranged between the outer edge of the chin and the face contour of the patient, and the transition arc is matched with the face contour in shape.

Further, the breathing machine face guard still includes the inlet channel with the air duct coincidence, and inlet channel outside laminating has guide port and locking means, it has the support to articulate between guide port and the breathing machine face guard, and the diameter of guide port is less than inlet channel.

Furthermore, the locking device comprises a hinge rod hinged on two sides of the radial direction of the guide pipe and a bulge positioned on the air inlet channel, and one side of the hinge rod facing the air inlet channel is provided with a notch matched with the bulge in shape.

Further, bellied cross section is "loudspeaker form", and the arch includes body and head, and the head is divided into 4 at least strips towards all around, and the mutual interval between the strip, and the strip is along notch to air intake channel's direction coincidence gradually, and the diameter of head is greater than body.

The noun explains: trumpet-like refers to the shape of a flower bone similar to morning glory.

After adopting above-mentioned scheme to realize following beneficial effect 1, the transition arc and the profile lock of patient face of chin to keep the fixed of breathing machine face guard, the skin or the wound of patient's chin this moment of chin evagination are wrapped up by the part of evagination afterwards, avoid skin or wound by mask oppression itself.

2. Because the Mobius structure is arranged, the skin or the wound on the two sides of the nasal wing and the nasal bridge of the patient is always positioned on the surface of the Mobius ring when being adhered with the Mobius ring structure, at the moment, the skin or the wound presses the Mobius ring inwards, the skin or the wound is in clearance fit with the arc-shaped groove, the oppressive feeling of the skin or the wound is reduced, and meanwhile, when the surface of the patient is not provided with the wound, the contact surface of the Mobius ring structure with the skin of the patient is increased by the characteristic of the single surface of the Mobius ring structure, so that the infection of the patient is avoided.

3. Owing to set up the push pedal, medical personnel will inhale the phlegm operation this moment and go on in the condition that does not need the tube drawing, prevent that patient's larynx sputum from spilling and falling and pollute medical environment, have simplified the operation flow simultaneously, and the patient has promoted operating efficiency.

4. The push plate is automatically returned under the action of the torsion spring after the sputum suction is finished, and the notch of the chin slides in along the notch of the air duct, thereby avoiding the phenomenon of dislocation caused by the vibration of the push plate and keeping the sealing property

5. The convex head is converted into a convergence process by the opening and closing process in the buckling process, the convex head is opened and closed again after the buckling is completed, the notch is limited and clamped at the moment, and the tube drawing of a patient is avoided.
