Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a pulse-type autonomous oxygen inhalation device. Background Art

[0002] An oxygen inhalation device is a medical device that is mainly used to provide oxygen to patients who need supplemental oxygen to improve their breathing conditions.

[0003] At present, nasal cannula or open mask is commonly used in clinical practice for oxygen inhalation. After the oxygen is turned on, it flows out continuously. When exhaling, the oxygen does not stop flowing out, which leads to oxygen waste. An existing normal pressure saturated oxygen inhalation uses a non-invasive ventilator, which is expensive and burdens patients. Another existing pulse oxygen supply method on handheld oxygen concentrators and other equipment has a fixed oxygen concentration and is not suitable for all patients, especially patients with diseases such as chronic tracheitis and emphysema, who should not have too high an oxygen concentration. Moreover, this oxygen supply method is set at a certain frequency, and oxygen is supplied at regular intervals to allow the oxygen inhaler to adapt to this frequency. However, due to changes in activity intensity, a person's breathing frequency will change accordingly. Oxygen supply at a fixed frequency will be uncomfortable or even unsuitable.

[0004] From this we can see that current oxygen supply equipment has the disadvantages of oxygen waste and high equipment cost, as well as the problem that the oxygen supply method makes patients uncomfortable. Summary of the Invention

[0005] To this end, the present invention provides a pulsed autonomous oxygen inhalation device to solve the problems raised in the above background technology, namely, the high price of current oxygen supply products, fixed oxygen concentration and oxygen supply frequency, that is, the oxygen supply method makes patients uncomfortable, and a large amount of oxygen is wasted.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A pulsed autonomous oxygen inhalation device comprises an oxygen inhalation mask and a shell, wherein a gas circulation chamber and a mixed gas chamber are provided in the shell, a gas circulation chamber inlet connected to the mixed gas chamber is provided at the lower end of the gas circulation chamber, the oxygen inhalation mask is connected to the gas circulation chamber, and an inhalation valve disc for unidirectional flow of gas from the gas circulation chamber to the oxygen inhalation mask is provided on the side of the oxygen inhalation mask connected to the gas circulation chamber, a spring limit frame is provided in the gas circulation chamber, the spring limit frame is fixedly connected to the inner wall of the shell, a first spring is provided on the upper side of the spring limit frame, the upper end of the first spring is connected to a breathing active silicone diaphragm, the breathing active silicone diaphragm is clamped on the upper end of the shell and the edge of the breathing active silicone diaphragm is sealed with the inner wall of the shell, a magnetic sheet is embedded in the breathing active silicone diaphragm, a second spring is provided on the lower side of the spring limit frame, the lower end of the second spring is connected to a magnetic rubber plate, and the magnetic rubber plate blocks the gas circulation chamber inlet under the action of the second spring.

[0008] Wherein, the shell is provided with an oxygen inlet for oxygen to enter the mixed gas chamber.

[0009] An air inlet chamber is further provided below the mixed gas chamber, an oxygen storage airbag is provided in the air inlet chamber, and an oxygen inlet and outlet communicating with the mixed gas chamber are provided on the top of the oxygen storage airbag.

[0010] The lower end of the mixed gas chamber is provided with a mixed gas chamber inlet for gas to flow in, and the mixed gas chamber inlet is provided with an air intake diaphragm for gas to flow unidirectionally from the air inlet chamber into the mixed gas chamber.

[0011] Wherein, an air inlet for air to enter the air inlet chamber is opened at the lower end of the shell.

[0012] The pulsed autonomous oxygen inhalation device further comprises an upper cover covering the top of the shell and a base connected to the bottom of the shell, wherein the upper cover is provided with an air vent.

[0013] Wherein, the gas circulation chamber is provided with a gas circulation chamber outlet on the side connected to the oxygen inhalation mask, and an inhalation pipeline is provided between the gas circulation chamber outlet and the oxygen inhalation mask.

[0014] Wherein, the oxygen inhalation mask is also provided with an exhalation valve flap for gas outflow.

[0015] Wherein, a limiting groove for clamping the respiratory active silicone diaphragm is provided at the upper end of the shell.

[0016] The present invention has the following advantages: when a patient inhales, negative pressure is generated in the gas circulation chamber, causing the respiratory active silicone diaphragm to bounce downward, and the magnetic attraction force generated by the magnetic sheet and the magnetic rubber plate causes the magnetic rubber plate to overcome the resistance of the second spring and move upward, the inlet of the gas circulation chamber is opened, and the oxygen and air in the mixed gas chamber enter the gas circulation chamber, thereby adjusting the oxygen concentration inhaled by the patient. At the same time, the patient can achieve autonomous oxygen inhalation according to his or her own breathing rhythm; this not only makes oxygen inhalation smoother and improves the oxygenation effect, but also reduces oxygen waste.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present application will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0022] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, this embodiment provides a pulsed autonomous oxygen inhalation device, including an oxygen mask 22, a shell 3 connected to the oxygen mask, an upper cover 1 covering the top of the shell 3 and a base 19 connected to the bottom of the shell. The upper cover is provided with an air vent 2 to allow air to enter the shell 3.

[0024] The shell 3 is divided into a gas circulation chamber 25, a mixed gas chamber 26 and an air intake chamber 27 from top to bottom. The lower end of the gas circulation chamber 25 is provided with a gas circulation chamber inlet 11, and the lower end of the mixed gas chamber 26 is provided with a mixed gas chamber inlet 15. When oxygen is inhaled, the chambers are interconnected.

[0025] The oxygen mask 22 includes an inhalation valve flap 23 and an exhalation valve flap 24. The patient can control the inhalation valve flap 23 and the exhalation valve flap 24 according to his or her own breathing frequency to perform autonomous oxygen inhalation, making oxygen inhalation smoother and preventing oxygen waste.

[0026] The oxygen mask 22 is connected to the gas circulation chamber 25 through the intake pipe 21 on the side where the intake valve flap 23 is located. The gas circulation chamber 25 is provided with a gas circulation outlet 20 at one end connected to the intake pipe 21. When inhaling oxygen, the gas flows from the gas circulation chamber 25 through the intake pipe 21 into the oxygen mask 22.

[0027] A spring limit frame 7 is provided in the gas circulation chamber 25. The spring limit frame 7 is fixedly connected to the inner wall of the shell 3, dividing the gas circulation chamber 25 into two parts, an upper part and an lower part. Since the spring limit frame 7 is a hollow support frame structure, the upper and lower parts of the gas circulation chamber are ensured to be connected. The spring limit frame 7 is used to fix the first spring 6 and the second spring 8; the first spring 6 is connected to its upper side, and the second spring 8 is connected to its lower side.

[0028] The lower end of the second spring 8 is connected to a magnetic rubber plate 9, which is used to flexibly seal the gas flow chamber inlet 11. The second spring 8 is in a pre-compressed state, and under the elastic force of the second spring 8, the magnetic rubber plate 9 blocks the gas flow chamber inlet 11.

[0029] The upper end of the first spring 6 is connected to a breathing silicone diaphragm 4. The breathing silicone diaphragm 4 is affected by the pressure of the gas circulation chamber, and its central area can elastically move up and down. A magnetic piece 5 is embedded in the breathing silicone diaphragm 4. The edge of the breathing silicone diaphragm 4 is sealed to the inner wall of the housing 3. The upper end of the housing 3 is also provided with a limiting groove 10, which allows the breathing silicone diaphragm 4 to be clamped in the limiting groove 10, thereby forming a closed space in the gas circulation chamber 25.

[0030] During inhalation, negative pressure is generated in the gas circulation chamber 25, and the respiratory active silicone diaphragm 4 overcomes the resistance of the first spring 6 and bounces downward. After the magnetic sheet 5 moves downward for a certain distance, the magnetic attraction between it and the magnetic rubber plate 9 is greater than the elastic force of the second spring 8, so that the magnetic rubber plate 9 overcomes the elastic force of the second spring 8 and moves upward, thereby opening the gas circulation chamber inlet 11, allowing the gas in the mixed gas chamber 26 to enter the gas circulation chamber 25.

[0031] An oxygen input port 12 is provided on the shell for connecting an oxygen supply device such as an oxygen concentrator or an oxygen cylinder so that the oxygen supply device can continuously input oxygen into the mixed gas chamber 26. An inhalation diaphragm 14 is also provided at the inlet 15 of the mixed gas chamber, which is opened in the inhalation state.

[0032] An air inlet 16 is provided at the lower portion of the housing 3 to allow air to enter the air intake chamber 27;

[0033] An oxygen storage bag 18 is provided in the air inlet chamber 27 for storing and supplying oxygen. An oxygen inlet and outlet 17 connected to the mixed gas chamber 26 is provided on the top of the oxygen storage bag 18. During inhalation, the oxygen in the oxygen storage bag 18 enters the mixed gas chamber 26 through the oxygen inlet and outlet 17. At this time, the pressure in the oxygen storage bag 18 drops to normal pressure, and the inhalation diaphragm 14 is opened, allowing the gas in the air inlet chamber 27 to enter the mixed gas chamber 26, thereby adjusting the concentration of oxygen inhaled by the patient and improving the oxygenation effect.

[0034] When the patient exhales, the exhalation valve flap 24 opens, the inhalation valve flap 23 closes, the gas circulation chamber 25 returns to normal pressure, and the respiratory active silicone diaphragm 4 rises under the action of the first spring 6. As the distance between the magnetic sheet 5 and the magnetic rubber plate 9 gradually increases, the magnetic attraction between the magnetic sheet 5 and the magnetic rubber plate 9 weakens. At the same time, under the action of the second spring 8, the magnetic rubber plate 9 descends and blocks the gas circulation chamber inlet 11.

[0035] The oxygen continuously inputted into the mixed gas chamber 26 by the oxygen supply device is temporarily stored in the oxygen storage bag 18 so as to provide the required oxygen during the next oxygen inhalation.

[0036] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
