Abstract

The utility model relates to a four-head belt of a noninvasive ventilator, which comprises an I-shaped head belt and a frame-shaped connecting belt sleeved with a trachea plug hole of the ventilator, wherein the tail ends of four tying belts of the I-shaped head belt are respectively connected with four corners of the connecting belt, and the tying belts are sleeved with pressure reducing pipes; and the air leakage of the patient in noninvasive ventilation is greatly reduced by filling the gap between the mask and the skin, and the ventilation effect is not influenced while the pressure of the mask is not increased.

Description

Four-head belt of noninvasive ventilator

Technical Field

The utility model relates to the field of medical appliances, in particular to a four-head belt of a noninvasive ventilator.

Background

The non-invasive positive pressure ventilation (NIPPV) technique is a technique in which a ventilator is connected to a patient through a mask to complete auxiliary ventilation, and is widely used for treatment and rescue of respiratory failure. In order to prevent air leakage and ensure the ventilation effect, continuous positive pressure ventilation is needed to maintain the respiratory function of a patient during NIPPV treatment, the ventilation mask is tightly buckled on the mouth and the nose of the patient by four head bands, the facial skin is continuously pressed, erythema and damage are easy to occur, and pressure injury related to cheek and behind-the-ear appliances is formed. Meanwhile, the tolerance and the compliance of the patient to the treatment of the breathing machine are directly reduced, and the treatment of the primary disease is influenced. Prolonging the hospitalization time, increasing the medical cost and reducing the satisfaction degree of the patient.

Gauze pads, hydrocolloid dressing, transparent application, foam pastes and the like are commonly used at present, and are cut into the shapes of 'eight', 'herringbone', 'I' and the like to be pasted on the face of a patient. These methods all have certain effects, and also present certain disadvantages, such as the materials are easy to curl and fall off, need to be frequently replaced, increase the economic burden of patients, and influence the eating and comfort of patients due to continuous adhesion to the faces of patients.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a nasal mask for preventing the nasal face skin from frequently moving up, down, left and right and rubbing with a nasal mask and the like along with respiratory motion to cause pressure sores; and the space between the mask and the skin is filled, so that the noninvasive ventilation air leakage of a patient is greatly reduced, the mask pressure is not increased, and the ventilation effect is not influenced.

The utility model relates to a four-head belt of a noninvasive ventilator, which adopts the following technical scheme: the breathing machine trachea plug hole connecting strap comprises an I-shaped headband and a frame-shaped connecting strap sleeved on a breathing machine trachea plug hole, the tail ends of four tying straps of the I-shaped headband are respectively connected with four corners of the connecting strap, and the tying straps are sleeved on a decompression tube.

Furthermore, four corners on the end surface of the connecting belt are respectively provided with a convex part, and the tail ends of the four tying belts of the H-shaped head belt are provided with a plurality of adjusting holes which are clamped with the convex parts.

Further, the tube wall thickness of the decompression tube is 8mm, the length is 100mm, and the inner diameter is 10 mm.

Further, the decompression tube is molded from an elastic rubber material.

Further, the I-shaped head band is provided with a plurality of exhaust holes.

Compared with the prior art, the utility model has the following beneficial effects:

1. the high-pressure-resistant disinfection elastic pressure reducing pipe is sleeved on the lacing tape to prevent the nasal face skin from frequently moving up, down, left and right and rubbing with the nasal mask and the like along with respiratory motion to cause pressure sores; the air leakage of the patient in noninvasive ventilation is greatly reduced by filling the gap between the mask and the skin, and the ventilation effect is not influenced while the pressure of the mask is not increased;

2. the pressure reducing pipe formed by elastic rubber materials has high absorbability and hydrophobicity, the inner layer can absorb water vapor and sweat exhaled from the mask, the outermost layer adopts a hydrophobic dressing technology, liquid can be locked, liquid cannot overflow due to pressure, and the stimulation of moisture to skin is prevented, so that a barrier effect is realized on a pressed part;

3. the adoption corresponds regulation hole and convex part block, not only saves fixed time, still can be according to the patient adjustment headgear length of difference, satisfies the demand of different patient's fixed face masks.

Drawings

The accompanying drawings, which are described herein to provide a further understanding of the application, are included in the following description:

fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

Referring to fig. 1, the four-head belt of the noninvasive ventilator of the embodiment includes an i-shaped head belt 1 and a frame-shaped connecting belt 2 sleeved on a trachea plug hole of the ventilator, four corners of an end surface of the connecting belt 2 are respectively provided with a convex part 21, the ends of four lacing belts of the i-shaped head belt 1 are provided with a plurality of adjusting holes 11 clamped with the convex parts 21, the lacing belts are sleeved with a decompression tube 3, and the decompression tube 3 is formed by an elastic rubber material.

Further, the wall thickness of the decompression tube 3 was 8mm, the length was 100mm, and the inner diameter was 10 mm.

Further, the h-shaped headband 1 is provided with a plurality of vent holes 12.

The working principle of the utility model is as follows: when the noninvasive ventilator is used, the noninvasive ventilator is covered on the face, the frame-shaped connecting band 2 is sleeved on the noninvasive ventilator trachea plug hole, the I-shaped head band 1 is fixed behind the brain, the four tying bands of the I-shaped head band 1 are stretched towards the face from the back of the brain, and the adjusting hole 11 on the tail end of each tying band is clamped on the convex part 21 of the frame-shaped connecting band 2 according to proper tightness.

The pressure reducing pipe 3 is sleeved on the lacing belt, so that the stress area is increased, the pressure of the lacing belt on the face is reduced, and the nasal face skin is prevented from frequently moving up, down, left and right and rubbing with a nasal mask and the like along with respiratory motion to cause pressure sores; the air leakage of the patient in noninvasive ventilation is greatly reduced by filling the gap between the mask and the skin, and the ventilation effect is not influenced while the pressure of the mask is not increased; the pressure reducing pipe formed by elastic rubber materials has high absorbability and hydrophobicity, the inner layer can absorb water vapor and sweat exhaled in the mask, the outermost layer adopts a hydrophobic dressing technology, liquid can be locked, liquid cannot overflow due to pressure, and the moisture is prevented from stimulating the skin, so that a barrier effect is realized on a pressed part.
