Description

Novel prevent pressing noninvasive face guard of sore leak protection gas

Technical Field

The utility model relates to the technical field of medical equipment, the more specifically novel prevent pressing wound face guard of sore leak protection gas that says so.

Background

At present, a noninvasive ventilator becomes an important respiratory support means for treating respiratory failure, and in clinical use, particularly for patients with facial emaciation, the mask of the noninvasive ventilator is easy to be attached and air leakage is not tight, so that the minute ventilation of the patients is low, and the treatment effect is poor; in order to use the noninvasive ventilator mask for long-time close fitting, skin erythema and damage easily occur at compression points such as the two sides of the nasal alar part, the nasal bridge, the cheekbones at the two sides, the mandible and the like, and then related pressure sores of medical instruments occur. At present, a hydrocolloid dressing or a foam dressing is clinically used to be stuck at the nose bridge and the parts, which are easy to be pressed, of the cheekbones on two sides of a patient, and the shapes of the dressings are different because of self trimming by nurses; the dressing can have adhesive residues on the face of a patient, so that the patient is easy to feel uncomfortable; the foam dressing is opaque in material, so that the change of the skin condition cannot be observed when the foam dressing is stuck on the face of a patient; and secondary skin damage such as skin peeling may occur due to pulling when the dressing is changed by tearing. At present, the O-shaped gauze pad is also cut by gauze in clinic, but because the O-shaped gauze pad cannot be fixed, the O-shaped gauze pad is easy to shift in the treatment process of the noninvasive ventilator, so that the treatment effect is influenced.

In the use process of the existing noninvasive mask, because the existing noninvasive mask is considered to be adhered to the face of a patient by using foam dressing, the cleaning is difficult, and the skin of the patient is damaged and pressed sore can be caused by long-time adhesion, in order to solve the problem, Chinese patent (No. CN 212914147U), the noninvasive mask is disclosed, the noninvasive mask comprises a mask main body, an air inlet, a buffer decompression air cushion layer, an air cushion decompression layer, an air inlet channel of the buffer decompression air cushion layer, an exhaust hole and at least 4 head belt fixing buckles, wherein the air inlet is positioned on the mask main body and communicated with the inner side of the mask main body, the air cushion decompression layer is positioned at the bottom edge of the mask main body, the buffer decompression air cushion layer is arranged at the bottom edge of the air cushion decompression layer, the air inlet channel of the buffer decompression air cushion layer is arranged at the inner side of the mask main body, and the air inlet channel of the buffer decompression air cushion layer is communicated with the air inlet and the buffer decompression air cushion layer, the exhaust hole is arranged on the buffer pressure reducing air cushion layer, and a better pressure sore prevention effect is achieved.

This scheme still has some weak points in using, because there is not the face guard of wound need be connected with the breathing machine, including the bronchus connector, stomach tube connector etc. when meetting the face guard and need connect breathing machine and stomach tube, mismatch the condition that leads to the unable using appears very easily, simultaneously, because most pressure sore takes place in the bridge of the nose, this utility model does not prevent to the bridge of the nose that pressure sore carries out effectual taking precautions against. Therefore, there is a need to further improve the utility and versatility of noninvasive masks.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a novel prevent pressing wound face guard of sore leak protection gas, its main aim at overcome the above-mentioned not enough and shortcoming that prior art exists.

The utility model adopts the technical scheme as follows:

the utility model provides a novel prevent pressing noninvasive face guard of sore leak protection gas, includes the face guard body, the face guard body is including the cover body, the fixed frame of head and solid tight area, the fixed frame symmetry of head set up in cover body upper portion both sides, solid tight area symmetry set up in cover body lower part both sides, the cover body is hollow structure, and this hollow structure is equipped with patient's facial contact side ring and prevents pressing the pad, cover body laminating nasal cavity is equipped with the nasal part pad, and this nasal part floorcloth is equipped with the through hole, upper portion is equipped with the relief pressure valve in the cover body, the cover body passes through the relief pressure valve control cover internal pressure.

Furthermore, the pressure-proof pad has three layers, namely a hydrocolloid layer, a foam absorbing pad layer and a semi-permeable waterproof film layer from inside to outside.

Further, the foam cushion layer is an absorption cushion layer using polyurethane foam without adhesive.

Furthermore, the head fixing frame is of an L-shaped glasses frame structure.

Furthermore, the front side of the mask body is provided with three connectors, namely a stomach tube connector, a sputum suction connector and a fiberbronchoscope connector.

Furthermore, the contact surface of the nose pad and the nose bridge of the patient is made of a silica gel sheet.

Through the above-mentioned right the utility model discloses a description compares with prior art, the advantage of the utility model lies in:

1. the utility model discloses a set up the cover body and establish the three-layer with patient's contact face ring and prevent pressing the pad, from the lining to outer be hydrocolloid layer, foam absorbing cushion layer and semi-permeable waterproofing membrane layer respectively, through this setting, effectually prevent the facial skin erythema of patient, the damage presses the sore, simultaneously, utilizes to be equipped with miniature through hole in cover body laminating nose pad portion, plays the effect of decompression, adopts the silica gel thin slice material with nose bridge portion contact surface moreover, and further prevent that the sore is pressed to the patient's bridge of the nose.

2. The utility model discloses an upper portion sets up adjustable relief pressure valve in the cover body, adjusts cover internal pressure through the relief pressure valve control, can carry out corresponding regulation to different patients' pathological characteristics etc. and cover internal pressure control at reasonable within range, further prevents to press sore and disease to wear the travelling comfort, and novel structure is fit for promoting.
