Description

Novel noninvasive ventilator mask

Technical Field

The utility model relates to a face guard, especially a new-type noninvasive ventilator face guard.

Background

As is well known, respiratory masks are widely used in continuous positive pressure ventilation therapy for various respiratory diseases and sleep disorders, such as obstructive sleep apnea or other ventilation therapies such as non-invasive positive pressure ventilation, and the superior therapeutic capabilities of respiratory masks make respiratory masks the first therapeutic instrument for patients with respiratory diseases and sleep disorders.

However, the bottom end of the existing breathing machine mask is directly contacted with the face of a patient and is pressed on the face of the patient, so that the face of the patient generates indentation, the pressing time is long, and the face of the patient is pressed and injured, and the existing breathing machine mask adopts a fixed face design, so that the universality of patients with different faces is poor, and the fitting degree is low.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve above-mentioned prior art's shortcoming, provide a commonality strong, laminating degree high, to patient's face no indentation crush injury, patient comfortable new-type noninvasive ventilator face guard, satisfied the patient when using the ventilator face guard, comfortable, the commonality strong, the high demand of laminating degree.

The utility model provides a technical scheme that its technical problem adopted: the novel noninvasive ventilator mask comprises a mask body, wherein an inflatable airbag arranged along the outline of the mask body is fixed on the bottom surface of the mask body, a communicating pipe communicated with the cavity of the mask body is fixed on the mask body, the communicating pipe is a 90-degree bent pipe, and an inflation and deflation device is installed on the mask body; the inflation and deflation device comprises a needle cylinder fixed on the mask body, a first air one-way air valve and a second air one-way air valve are arranged on the side part of the needle cylinder, a communicating air pipe is arranged between the outlet of the needle cylinder and the inlet of the first air one-way air valve, a second air one-way air valve is arranged on the side part of the communicating air pipe in a communicating way, the air inlet and outlet modes of the first air one-way air valve and the second air one-way air valve are opposite, a conducting pipe is connected between the outlet end of the first air one-way air valve and the inflatable; first bandage and second bandage are installed respectively to the left and right both sides of face guard body, are fixed with father face magic subsides on the medial surface of first bandage, are fixed with mother's face magic subsides on the lateral surface of second bandage. The mask body is used for covering the mouth and the nose of a patient, so that the breathing part of the patient is covered; the inflatable air bag has the advantages that when the mask body covers the face of a patient, the mask body is in flexible contact with the face of the patient, and the face of the patient is not indented or crushed; the communicating pipe fitting is used for being in butt joint with a hose on a breathing machine in a matching mode, and the communicating pipe fitting is a 90-degree bent pipe and has the effect that when the communicating pipe fitting is in butt joint with the hose on the breathing machine, the pulling force of the breathing machine hose on the mask body is transverse rather than longitudinal, so that the situation that the mask body is easily pulled down from the face of a patient can be reduced; the inflation and deflation device has the functions of inflating the inflatable air bag or releasing part of gas so that the inflatable air bag has softness adjustment to adapt to patients with different face shapes, wherein the face of some patients has more flesh, at the moment, the inflatable air bag can be inflated with enough gas so that the inflatable air bag is matched with the face of the patient, if the face shape of the patient is thin and the bone on the face is obvious, at the moment, the inflatable air bag needs to be deflated so that the deformation of the inflatable air bag is increased, and the inflatable air bag can be completely attached to the face of the patient after the deformation of the inflatable air bag is increased; the first air one-way air valve and the second air one-way air valve are used as one-way ventilation valves, and only gas can enter in one way, wherein the first air one-way air valve and the second air one-way air valve are existing products on the market, and can be products of companies such as Flowangming plastic product factories in the moral region of Fushan City, and fluid control equipment Limited of Jinan Euride; the air release valve is used for performing air release operation on the inflatable air bag so as to enable the inflatable air bag to be softened, and is an existing product on the market, and can be selected from products of Beijing Sihai auspicious cloud vacuum technology Limited company and a Sancheng gold through-fluid equipment factory in Wenzhou city; the working principle of the inflation and deflation device is as follows: when the inflatable airbag needs to be inflated, only the needle cylinder pull rod needs to be pulled to extract air, at the moment, the first air one-way air valve is in a closed state under the air pressure, and the second air one-way air valve is in a smooth state under the air pressure, so that the outside air can be sucked into the needle cylinder cavity through the second air one-way air valve, then the needle cylinder pull rod is pressed, the air in the needle cylinder is extruded out, at the moment, the second air one-way air valve is in a closed state under the air pressure, and the first air one-way air valve is in a smooth state under the air pressure, so that the air in the needle cylinder is injected into the inflatable airbag; here, the first bandage, the second bandage, the male surface magic tape and the female surface magic tape have the effect that the mask body cannot be fixed on the face of a patient.

Further perfect, the outer end of intercommunication pipe fitting is equipped with intake pipe and joining in marriage the pipe, and the cross-section of intake pipe is greater than the cross-section of joining in marriage the pipe, installs the sealing washer on the outer terminal surface of intake pipe, and it has a set of bull stick that sets up along intake pipe center equipartition to articulate on the outer profile surface of intake pipe, and the outer end of each bull stick all is fixed with the piece that colludes, installs the torsional spring that drives the bull stick and rotate towards joining in marriage the pipe direction in the. The sealing ring plays a role in sealing the face shield joint; here, the effect of the rotating rod, the hook block and the torsion spring is that the mask joint can be conveniently fixed at the position of the communicating pipe fitting in a dismounting way (as shown in figure 5).

Further perfection, the air inlet pipe is provided with threads, the threads are connected with screwing press blocks, and pressing rings matched with the outer ends of the rotating rods are fixed at the inner ends of the screwing press blocks. The screw thread, the screwing press block and the pressing ring have the effects that when the mask joint is separated from the communicating pipe fitting, the screwing press block is only needed to be screwed and the pressing ring is pressed at the outer end of each rotating rod, so that each rotating rod rotates clockwise, and the hook block on each rotating rod is separated from the hook column, so that the mask joint can be separated from the communicating pipe fitting (as shown in figure 5).

The utility model discloses profitable effect is: the utility model has the advantages of ingenious design, it is reasonable, utilize the face guard body can cover patient's mouth and face, utilize and aerify the gasbag and can with patient's the soft contact of face, avoid making patient's face by the extrusion of hard thing and cause the indentation, the time of pressure has been prolonged can lead to the fact the condition emergence of weighing injury to patient's face, the utilization is filled and is filled the gassing device and can be filled the gassing operation to aerifing the gasbag, thereby can be applicable to different fat thin patient's face type, it is higher to patient's face type laminating degree, the comfort level is higher, the effect is better, be worth popularizing and applying.
