Description

Novel noninvasive ventilator face guard

Technical Field

The utility model relates to a breathing machine face guard specifically is a novel noninvasive breathing machine face guard, belongs to medical instrument technical field.

Background

A noninvasive ventilator is a medical device commonly used in clinical medicine, which is connected to a patient through a mask to provide noninvasive positive airway pressure therapy for the patient. The face mask is used as an interface between the noninvasive ventilator and a patient to be in direct contact with the face of the patient, and plays an important role in the treatment process. Most noninvasive ventilator face guard that uses at present clinically is owing to structural the trompil that is used for supplying nasogastric tube to pass through that lacks, when having the treatment of noninvasive malleation to the patient who settles nasogastric tube, can only draw nasogastric tube from face guard and patient's contact surface, this moment because the direct oppression of face guard is on nasogastric tube, lead to inseparable with the laminating of patient's facial skin, the air leakage increase, in order to guarantee the effect of ventilating, need hang the head and take fixed step-up, long-time oppression will lead to the emergence that the sore was pressed to patient's part again.

For this reason, chinese patent CN 201420671375.6 discloses a respirator nose and face mask with a gastric tube insertion hole, wherein a through hole passing through the gastric tube is arranged below the corresponding part of the nose of the face mask body, and a sealing ring for sealing the gap between the gastric tube and the through hole is arranged on the through hole; the skirt edge for blocking leaked gas is arranged at the outer edge of the mask body and used for blocking gas overflowing from the mask and the skin of the head and face of a human body, so that the gas is prevented from hurting eyes of a patient, and the skirt edge can be made of cotton cloth and other materials. The technical scheme still has the following defects in clinical use:

(1) the sealing ring for sealing the gap between the gastric tube and the through hole is arranged on the through hole, the requirement on the tube diameter of the gastric tube is higher when the gastric tube is led out, the sealing ring cannot be completely sealed if the gastric tube is too thin, air leakage is easy to generate, the gastric tube with the proper tube diameter is tightly matched with the sealing ring, and the tube penetrating process is obviously retarded, time-consuming and labor-consuming.

(2) And because the perforation passing through the gastric tube lacks a corresponding plug cover, the mask can not be sealed when the gastric tube is not needed to be penetrated, and the gas leakage of the mask is caused.

(3) The skirt edge contacting with the face of the patient adopts cotton cloth material, the setting is not reasonable enough, the sealing effect is poor, and the mask is not comfortable enough to wear.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel noninvasive ventilator face guard to solve the above-mentioned defect that current noninvasive ventilator face guard exists.

The utility model discloses the technical scheme who adopts as follows:

Furthermore, the lower side edge of the mask body is provided with a skirt edge, the bottom surface of the skirt edge is provided with a circle of air bags, the air bags serve as an interface contacting with the face of a patient, and the top surface of the skirt edge is provided with a second air nozzle communicated with the air bags. Preferably, the air bag is made of a silica gel material.

Furthermore, hanging buckles and corresponding head hanging belts are further arranged on two sides of the outer portion of the mask body.

The noninvasive ventilator mask of the utility model is provided with a through hole for the nasogastric tube to pass through on the mask body, and the annular air bag is arranged below the through hole, after inflation, the nasogastric tube can be clamped and fixed through the inner ring of the annular air bag, and simultaneously, the gap between the through hole and the nasogastric tube can be sealed, so that the requirement on the pipe diameter is low when the nasogastric tube is penetrated, and the operation of penetrating the pipe is convenient for medical staff; the mask is also provided with a rubber plug for the through hole, so that the through hole can be plugged by the rubber plug when the nasogastric tube is not needed to be worn, and the use is more flexible. In addition, a circle of air bags are arranged on the bottom surface of the skirt edge at the lower side of the face mask and are used as a contact interface with the face of a patient, so that air leakage of the face mask can be effectively prevented, and pressure sores caused by long-time compression can be avoided. Therefore, the noninvasive ventilator mask has reasonable structural design and convenient use, and is very suitable for clinical popularization and use.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-5, the noninvasive ventilator mask comprises a mask body 1, wherein an airway tube 2 connected with a ventilator pipeline is arranged at the upper side of the mask body 1, and a through hole 3 for a nasogastric tube to pass through is further arranged at the position of the mask body 1 beside the airway tube 2; a hole seat 4 is arranged on the outer side surface of the mask body 1 above the through hole 3, a soft hanging belt 5 is movably sleeved on the hole seat 4, and the tail end of the soft hanging belt 5 is connected with a rubber plug 6 matched with the hole seat 4; a circle of annular air bag 7 is arranged at the position of the inner side surface of the mask body 1 below the through hole 3 along the hole edge, the inner ring aperture of the annular air bag 7 is smaller than that of the through hole 3 when the annular air bag 7 is inflated and expanded, and a first air nozzle 8 communicated with the annular air bag 7 is arranged at the position of the outer side surface of the mask body 1 above the corresponding annular air bag 7. The lower side edge of the mask body 1 is provided with a skirt edge 9, the bottom surface of the skirt edge 9 is provided with a circle of air bag 10, the air bag 10 is used as an interface contacted with the face of a patient, and the top surface of the skirt edge 9 is provided with a second air nozzle 11 communicated with the air bag 10. The air bag 10 is made of non-toxic soft silica gel material. The two sides of the outer part of the mask body 1 are also provided with a hanging buckle 12 and a corresponding head hanging belt (not shown in the figure).

When being used for settling the patient that has no malleation treatment of creating of this noninvasive ventilator face guard, only need select than face guard body 1's the little nasogastric tube in aperture 3's aperture can, it is low to the requirement of nasogastric tube pipe diameter, and the poling is convenient. Bind this noninvasive ventilator face guard at patient face back, aerify annular gasbag 7 from first air cock 8 with the syringe, the inner circle of aerifing back annular gasbag 7 can press from both sides tightly fixed to nasogastric tube, can also seal the clearance between through-hole 3 and the nasogastric tube simultaneously. The air bag 10 at the bottom of the skirt edge 9 is inflated by the injector from the second air nozzle 11, so that slight pressure is formed between the air bag 10 and the face of the patient, and the air leakage of the mask can be prevented, and pressure sores are avoided because the air bag 10 has large contact area and soft texture. When the nasogastric tube does not need to be penetrated, the hole seat 4 can be plugged by the rubber plug 6, so that the through hole 3 is sealed, and the mask can be used as a conventional mask.

The above-mentioned drawings are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications or equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
