The level of technology

The present invention relates to respiratory masks. Respiratory masks are used in several different situations for the treatment of respiratory disorders, such as obstructive sleep apnea. When treating the patient through a mask provided with a flow of breathable gas. Current designs of masks in General, include a frame or body mask, which can be attached to the tube through which flows the flow of breathable gas. To the frame of the mask is attached to a gasket that is pressed against the patient to ensure comfort and covers the nose and/or mouth of the patient. In addition, provision may be made for the forehead pad for absorbing facial mask on the patient's forehead. To hold the mask on the patient's head provides the straps.

One problem in the design of the mask is in the Assembly of the component parts of the mask. In some cases, to attach the strips of the mask skeleton mask in the masks used the retaining ring. One method of attaching the strip to the frame of the mask includes ultrasonic welding of the retaining ring with a skeleton mask for the detachable attachment of the strip to the frame of the mask. For a method of ultrasonic welding tools needed for Assembly mask that can increase the cost of the TB mask. Furthermore, although this method is effective to attach the strip to the frame of the mask, having permanently attached to the mask strip is an additional disadvantage. For example, some insurance companies reimburse the patient on a regular basis just replace the gasket. All-in-one joining strip to the frame of the mask does not allow the patient to replace just the gasket. Due to the lack of insurance indemnity the patient in some cases postpone the replacement of the mask or forced to pay for a new mask at his own expense. Moreover, the mask can be difficult to clean when the gasket and the frame mask is in the collection, resulting in possible unsanitary conditions.

In another method of attaching the strip to the mask, separate the retaining ring attaches the strip near its edges through the use of the connection protrusion and the recess or on the outer or on the inner side of the strip. In another way, the gasket may be attached to the frame of the mask by placing the edges of the strip between the frame mask and ring. In any case, the attachment of the strip to the frame of the mask using a retaining ring, separated from the strip, may be inconvenient and time-consuming. For example, it can be difficult to properly align the gasket and the retaining ring landlease attaching the strip to the frame of the mask.

Another challenge in the design of the mask is patient comfort. Existing masks can be uncomfortable and unable to fit different shapes and/or dimensions of the head. For example, the forehead pad can be hard and therefore not appropriate for the form of various foreheads. In other masks forehead pads can be adjustable, but for many masks adaptation to different shapes and/or dimensions of the head is difficult and, therefore, undesirable. In addition, forehead pads can be made of material that absorbs water. As a result, water may remain in the forehead pad after cleaning. In addition, the forehead pad can stick the sweat of the patient. Both of these situations can lead to unsanitary conditions.

The invention

One aspect of the present invention relates to a respiratory mask for use in the system of respiratory therapy. The mask includes a frame mask, the gasket and the retaining element. The retaining element is embedded inside the strip and attaching the strip to the frame of the mask. In a particular embodiment, from the retaining element through the gasket tabs are used to attach the retaining element to the frame of the mask. On the frame of the mask can envisage Matematica groove for receiving the gasket and insert the retaining element.

Another aspect relates to a forehead pad attached to the frame mask for selective adjustment of the frame of the mask to the patient's head. Forehead pads can be adjusted independently from one another, so the mask can be a good approach to many different patients, as well as to adapt to the movements of the patient. In one embodiment, the forehead pads can define a corrugated region, which can be located in the slit groove of the frame mask.

In particular, the annular groove 50 has a generally U-shaped f the RMU in cross section and has a thickness of, suitable to accommodate the strip 40 and the retaining element 42. When assembling the device 10 of the mask tab 48 is inserted into the section 32 for receiving the tongue, and the block 16 of the strip is inserted in the annular groove 50. In the present embodiment, the tongue 48 is a protrusion configured to insert into the receiving section 32 for the tongue, which is a hole in the shell 20 of the mask. Then the tabs 44 and 46 of the retaining element 42 are pressed, respectively, in sections 28 and 30 for receiving the reeds, Sedekias in the shell 20 of the mask. Both reed, and 44 and 46, have a hook shape to engage the relevant sections 28 and 30 for receiving the reeds, which form the sites with the notch in the groove 50. In particular, the hook sections of the hook on the front side of the frame 14 of the mask (i.e. closer to the hole 24 and on the side opposite the annular groove 50).

On Figa shows a front view of the device of the mask 10, which shows a section along the line 4B-4B for pigv and a section along the line 4C-4C for Figs. Together Figa-4C show the connection between the frame of the mask 14 and the block 16 of the strip. Figs is a closeup of the broken engagement between the tongue 44 of the retaining element 42 and section 28 for receiving the tongue of the shell 20 of the mask. As shown in the drawing, the retaining element 42 is embedded into the strip 40 so clicks the zoom, the gasket 40 completely surrounds the contour of the retaining element 42 on all sides. Together, the gasket 40 and the retaining element 42 are arranged inside the annular groove 50. In this example, U-shaped annular groove 50 includes three sides 50a, 50b and 50c. The gasket 40 surrounds the retaining element 42 so that the gasket 40 is located outside from all three sides (50a, 50b and 50c) of annular groove 50. In one embodiment, the elastic nature of the strip 40 may allow the block 16 pads fit to enter into the annular groove 50, as the gasket 40 is slightly compressed for insertion into the groove 50 and is in contact at least with the sides 50A and 50b of the groove 50 and, in one embodiment, also in contact with the side of 50c. The tongue 44 of the retaining element 42 projects from the strip and is located around the site 28 for reception of the tongue. The tab 44 may be elastic and have a form suitable for bending around the site 28 for reception of the tongue. Hooked section 52 of the tongue 44 is latched in section 28 for the reception of the tongue for attaching block 16 of the strip to the shell 20 of the mask as soon as the hook 52 is opposite the front side 54 of section 28 for receiving the tongue.

FIGU is a view in section of one of the forehead pads 18, Kotor, which includes the area of 60 pads and tapered corrugated region 62. In one embodiment, the forehead pad 18 may be made of a rubber material such as silicone, thermoplastic elastomer, etc. As shown, the region 60 of the pad has a convex shape and is pressed to the forehead of the patient. Corrugated region 62 passes from the region of 60 pads, forming an internal cavity 64 and an air channel 66, which ends on castrandom the tip 70. The internal cavity 64 allows the corrugated region 62 to bend so that the region of 60 pads can remain in continuous contact with the patient's forehead. Air channel 66 prevents the forehead pad 18 to adhere to the forehead of the patient, and also contributes to the collection of liquids resulting from cleaning of the mask and/or sweating.

Pointed tip 70 is configured to insert into one of the slots 34 of the frame 14 of the mask. After inserting a pointed tip 70 into the slot 34 of the corrugated region 62 may be selectively adjusted within the slots 34 on certain provisions defined by the grooves 72, 74, 76 and 78. For example, if it is desirable that the frame 14 of the mask was farther from the patient's face, the forehead pad 18 can be adjusted so that the slit 34 was hooked groove 72 (as shown on Figv). If it is desirable that the frame 14 of the mask was located closer to the face, forehead pad 18 can the t regulated so what with slit 34 engages the groove 78. In addition, the forehead pad 18 can be moved to different vertical positions on the slit 34 and thus relative to the frame 14 of the mask. The slot 34 includes multiple grooves, in particular three grooves, which are presented in figure 3 and in the section on FIGU, namely the upper groove 34a, the average groove 34b and the lower groove 34c. As shown in Figv, forehead pad 18 is located in the middle groove 34b. If you want the frame 14 of the mask was located lower relative to the patient's scalp, forehead pad 18 can be adjusted so as to be placed in the upper groove 34a of the slot 34. If you want the frame 14 of the mask was located higher relative to the patient's scalp, forehead pad 18 can be adjusted in such a way as to be located at the bottom of the groove 34c of the slit 34. Due to the elastic nature forehead pads 18, the position of the forehead pads 18 in the gap 34 can be adjusted automatically, for example, under the action of the patient's movements.

Then controllable mechanical ventilation of lungs is carried out without total myorelaxation in CMV-mode with respiratory volume of 6-8 ml/kg of body weight, peak flow rate of 50-65 l/min when using rectangular pattern of gas mixture supply or 65-85 l/min when using descending pattern of gas mixture supply. Inhalation-to-exhalation ratio is equal to 1:1.3-1:1.7, oxygen fraction on inhaling FiO2 is 0.25-0.3, compulsory breathing frequency is 10-16 breathings per 1 min, positive base pressure at the end of exhalation is equal to 3-4 cm of water column. Laryngeal mask is removed at the end of operation and auxiliary noninvasive ventilation of lungs is applied using air-oxygen mixture through facial mask in pressure breathing support mode of PSV. Thus, breathing support pressure is equal to 10-15 cm of water column. Oxygen fraction on inhaling FiO2 is equal to 0.25-0.3, positive pressure at the end of exhalation is equal to 2 3 cm of water column, trigger sensitivity is 2-3 l/min. Respiratory support is carried out until respiratory volume achieves the level not less than 6-7 ml/kg of body weight.

EFFECT: prevented negative effects accompanying total myorelaxation and trachea intubation anesthesia; fast respiratory rehabilitation of patients after operation.

FIELD: medicine.

SUBSTANCE: method involves applying sedation and setting laryngeal mask after having done epidural anesthesia. Next, controlled mechanical lung ventilation is carried out without total myorelaxation being applied in CMV mode selecting respiration volume being equal to 6-8 ml/kg of body weight, peak flow value of 50-65 l/min in applying rectangular gas mixture injection mode or 65-85 l/min in applying descending gas mixture injection mode. Inspiration-to-expiration ratio is selected 1:1.3-1:1.7, oxygen fraction FiO2 in inhaling being equal to 0.25-0.3, forced breathes frequency equal to 10-16 per 1 min, basic positive pressure value at the expiration end being equal to 3-4 cm of water column. The operation being over, the laryngeal mask is removed and auxiliary non-invasive lung ventilation with air and oxygen mixture is applied via facial mask in breathing support mode with PSV pressure. The support pressure is equal to 10-15 cm of water column on inhaling, oxygen fraction FiO2 in inhaling being equal to 0.25-0.3, positive pressure value at the expiration end being equal to 2-3 cm of water column, trigger sensitivity being 2-3 l/min. Respiration support is continued until respiration volume is not less than 6-7 ml/kg of body weight.

EFFECT: reduced risk of negative consequences; accelerated respiratory rehabilitation.

FIELD: medical equipment.

SUBSTANCE: invention is intended for application in drug administration under pressure, e.g. in aerosol drug administration system. In one version, face mask includes at least partially deformed case with surface contacting patient's face, nose bridge zone made in the upper case part, lower bent section where part of case is bent for positioning over face, and two holes in eye area at different sides of nose bridge. When the mask is placed over patient's face, the holes can be positioned over patient's eyes. Case is shaped so as the lower bent part is at least partially creased when mask is placed over face, and eye holes can form gap remaining open between internal edge of the hole and face part below eyes to provide outlet for mask placed over face with at least partial crease of lower bent section.

EFFECT: facial masks in different implementation version reduce aerosol particle inertia in areas close to nose, thus reducing amount of aerosol drug precipitation in eye area in the result of inertial sedimentation impact, while aerosol drug flow in mask cavity is maintained at level required for efficient drug supply to respiratory system of patient.

SUBSTANCE: invention concerns medicine, namely anaesthesiology, and can be used as anaesthetic means in laparoscopic gynaecologic operations in women of reproductive age. It is ensured by spinal anaesthesia that is followed by sedation with midazolam and propofol, and laryngeal masking ProSeal. Thereafter carbodioxyperitoneum is formed, while the patient is moved in Trendelenburg's position.

EFFECT: method allows providing adequate anaesthesia both in ALV and assisted respiration conditions without using muscle relaxants and narcotic analgesic with minimising the negative effect of intraabdominal hypertension owing to carbodioxyperitoneum.

SUBSTANCE: invention concerns medicine and can be used in treating the diseases accompanied with chronic tissue hypoxy. That is ensured by breathing of hypercapnic respiratory mixture created by the patient by mixing the proper exhaled and atmospheric inhaled air in a respiratory device representing a mixing chamber mask of capacity 0.8 litres. A mask is put on to the patient's face with embedding nose, mouth and chin and fixing so that to ensure free breathing, and adjusting the gaps the face and mask, herewith preventing air drags. A mask is individually matched for each patient depending on the rest exhalation volume. Its capacity shall be 100-150%, and dimensions shall not impede sight and head movements of the patient. The mask breathing is continuous to enable normal ventilation indicated by improved health state and achieved time of after-exhalation rest breath-holding 40-60 seconds.

EFFECT: method allows for considerable reduction of chronic tissue hypoxy due to continuous inhalation of the hypercapnic mixtures regardless of the environment.

FIELD: medicine.

SUBSTANCE: for treatment patients with hypogonadism with obstructive sleep apnea syndrome before substitutive therapy with androgens CPAP- therapy is carried out. After that CPAP- therapy is realised simultaneously with therapy with testosterone medications until its normal level is recovered.

EFFECT: method allows to carry out substitutive therapy of hypogonadism in patients with syndrome of obstructive sleep apnea, who have relative contraindications to administering androgens.
