Problems solved by technology

[0002] Although ordinary masks and nasal cannula oxygen therapy can provide a certain level of oxygen flow and oxygen concentration, they are both low-flow oxygen therapy equipment, so the inhaled oxygen concentration is easily affected by the surrounding environment, resulting in unstable oxygen concentration
Patients with hypoxemia are critically ill and have severe dyspnea. The traditional nasal cannula and mask oxygen supply are difficult to be effective. It is impossible to determine the actual oxygen concentration of the patient, and it is impossible to ensure that the patient's oxygen concentration remains stable.

Embodiment example 1

[0027] as attached figure 1 and figure 2 As shown, the present invention provides a technical solution: a method and device for increasing the oxygen storage space of nasal cannula oxygen therapy, comprising an aerosol mask 1 and a nebulizer 2, and two hollow threaded pipes 3, on the aerosol mask 1 There is a sealing interface 4 that is threaded with the sprayer 2, and the aerosol mask 1 is also provided with two nozzles 5 that are adapted to the hollow threaded pipe 3. The hollow threaded pipe 3 is provided with a filter mechanism 7, and the hollow threaded pipe 3 The outer sleeve is connected with a clamp 6, which can connect the nebulizer 2 and the threaded tube 3 with the aerosol mask 1. The volume of one aerosol mask is 210ml, the volume of the two threaded tubes 3 is 120ml, and the volume of the improved aerosol mask 1 is 120ml. For 210ml+120ml, the threaded tube 3 in the modified aerosol mask 1 collects the oxygen provided from the oxygen supply device during exhalati...

Embodiment 2

[0029] The scheme in the first embodiment will be further introduced below in conjunction with the specific working mode, see the following description for details:

[0030] like figure 1 , figure 2 , image 3 As shown in FIG. 5 , as a preferred embodiment, on the basis of the above method, the sealing interface 4 further includes an inner thread sealing sleeve 401, a limit block 402, a stainless steel spring piece 403, a pull rod 404 and a sealing rubber ring 405, The inner thread sealing sleeve 401 is also provided with a sealing rubber ring 405. The inner thread sealing sleeve 401 is provided with several arcuate stainless steel spring sheets 403. One side of the stainless steel spring sheet 403 is provided with a trapezoidal limit block 402, and the other side passes through it. Pull rod 404, the pull rod 404 is movably connected to the limit block 402, screw the inner thread sealing sleeve 401 of the sprayer 2 and the sealing interface 4 into the bolt, squeeze the limi...

Embodiment 3

[0033] The schemes in Embodiment 1 and Embodiment 2 are further introduced below in conjunction with the specific working modes, see the following description for details:

[0034] A method for increasing the oxygen storage space for nasal cannula oxygen therapy, comprising the steps of:

[0035] S1. Screw the inner thread sealing sleeve 401 of the sprayer 2 and the sealing interface 4 into the bolt, and squeeze the stop block 402, and compress the stop block 402 into the inner wall of the inner thread sealing sleeve 401 until the inner thread sealing sleeve 401 and the sprayer are connected. 2. Tighten it, and the gap between the inner thread sealing sleeve 401 and the sprayer 2 can be filled by the sealing rubber ring 405;

[0036] S2, connect the two threaded pipes 3 with the aerosol mask 1 through the nozzle 5;

[0037] S3. The air filter cotton 702 can be placed inside the pipe sleeve 701, and the outer threaded collar 703 is screwed into the inside of the pipe sleeve 701,...

Abstract

The invention discloses a method and device capable of increasing the oxygen storage space of nasal catheter oxygen therapy, and relates to the technical field of medical treatment, in particular to a method and device capable of increasing the oxygen storage space of nasal catheter oxygen therapy. The aerosol mask is provided with a sealing connector matched with a sprayer in a threaded mode, the aerosol mask is further provided with two pipe openings matched with the hollow threaded pipe, a filtering mechanism is arranged in the hollow threaded pipe, and the hollow threaded pipe is sleeved with a clamping hoop. According to the improved aerosol mask, the threaded pipe collects oxygen provided by the oxygen supply device during expiration, and a patient inhales an oxygen-rich gas mixture stored in the threaded pipe and the aerosol mask during inspiration, so that the patient is prevented from inhaling indoor air, and the oxygen inhalation concentration of the patient is increased.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and a device for increasing the oxygen storage space for nasal cannula oxygen therapy. Background technique [0002] Although ordinary mask and nasal cannula oxygen therapy can provide a certain level of oxygen flow and oxygen concentration, they are both low-flow oxygen therapy equipment, so the inhaled oxygen concentration is easily affected by the surrounding environment, resulting in unstable oxygen concentration. Patients with hypoxemia are in critical condition and have severe breathing difficulties. Traditional nasal cannula and mask oxygen supply are ineffective, and it is impossible to determine the patient's actual oxygen inhalation concentration, and it is impossible to ensure that the patient's oxygen inhalation concentration remains stable. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention provides a met...
