Description

Technical Field

[0001] The present invention mainly relates to the technical field of medical devices, and specifically, it is a movable and adjustable oxygen concentration oxygen inhaler. Background Art

[0002] With the development of medical technology, oxygen therapy has become an indispensable part in the treatment of various respiratory diseases, cardiovascular diseases and first aid processes. Traditional oxygen supply methods mainly rely on large fixed oxygen generators or oxygen cylinders. These devices often have problems such as inconvenient movement and limited usage scenarios. In addition, in actual applications, patients have relatively high requirements for the purity, humidity and temperature of oxygen. Especially in the case of long-term oxygen inhalation therapy, inappropriate oxygen conditions may cause discomfort to patients or even lead to other health problems.

[0003] The limitations of traditional oxygen supply devices are mainly reflected in the following aspects: Lack of mobility and flexibility: Large oxygen generators are usually large in volume and heavy in weight, making it difficult to transfer flexibly between different treatment environments; while oxygen cylinders, although relatively portable, have limited capacity and need to be replaced frequently, and also lack a convenient movement mechanism.

[0004] Poor stability: When used in a ward or other medical environment, due to uneven ground or accidental collision, etc., the device may be toppled over, which will not only interrupt the treatment process, but may also cause secondary harm to patients.

[0005] Difficulty in oxygen quality control: Traditional oxygen supply devices are difficult to simultaneously meet the precise regulation requirements for oxygen purity, humidity and temperature. Especially in cold seasons or for specific patient groups (such as the elderly, children), inhaling overly cold or overly dry oxygen may cause respiratory tract irritation or other complications. Summary of the Invention

[0010] Furthermore, two oppositely arranged elastic clamps are fixedly installed in the middle of the rear of the receiving groove.

[0011] The elastic clamp is of an arc structure.

[0012] Furthermore, an electric heating plate is provided at the bottom of the receiving groove.

Detailed implementation manners

[0018] In combination with the drawings and specific embodiments, the present invention will be further described. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0019] Embodiment: A movable and adjustable oxygen concentration oxygen inhaler As Figure 1-7 shown, a movable and adjustable oxygen concentration oxygen inhaler, the specific structure thereof includes: A machine housing 10, an oxygen generation assembly 20, and a support assembly 30. Universal wheels 101 are fixedly installed at the four corners of the bottom surface of the machine housing 10. A receiving groove 102 is opened on one side of the front surface of the machine housing 10. A humidifying bottle 40 is movably inserted into the receiving groove 102. An oxygen generation assembly 20 is provided inside the machine housing 10. The oxygen generation assembly 20 is communicated with the air inlet of the humidifying bottle 40 through a connecting pipe 201. The exhaust port of the humidifying bottle 40 is communicated with an oxygen mask through a hose. A support assembly 30 is provided at the bottom of the machine housing 10. A handle 50 is provided above the back of the machine housing 10; A control panel and several control buttons are provided on the front surface of the machine housing 10 for adjusting the oxygen generation concentration.

[0020] The above working principle: The universal wheels 101 installed at the four corners of the bottom surface of the machine case 10 enable the oxygen inhaler to move freely on the ground, facilitating medical staff to push it to different patients; the oxygen generation component 20 inside the machine case 10 operates. The compressor compresses air at high density. After removing impurities through the filter, the molecular sieve separates oxygen by using the principle of pressure adsorption and pressure reduction desorption. The oxygen is transported through the connecting pipe 201 to the humidifying bottle 40 in the receiving tank 102. After the humidifying bottle 40 humidifies the oxygen, the oxygen is transported to the oxygen mask through a hose for the patient to inhale; the support component 30 at the bottom of the machine case 10 supports the machine case 10, ensuring the stability of the equipment and ensuring that the equipment is stably placed during use to avoid tipping; the handle 50 above the back of the machine case 10 facilitates medical staff to push the equipment to move.

[0021] The support component 30 includes: a support plate 301, and the support plate 301 is movably installed at the center of the bottom surface of the machine case 10; support rods 302, and the two sides of the top surface of the support plate 301 are respectively hinged with the support rods 302, and the upper ends of the support rods 302 are respectively hinged to the bottom surface of the machine case 10; a push rod 303, and the middle part of the top surface of the support plate 301 is hinged with the push rod 303, and the upper end of the push rod 303 is connected to the position sliding component 60, and the position sliding component 60 can drive the push rod 303 to swing up and down.

[0022] When it is necessary to safely place the device, the upper end of the push rod 303 is driven to move forward by the sliding component 60. At this time, the push rod 303 swings downward and pushes the support plate 301 connected to it to move downward. At this time, the support rods 302 swing downward following the support plate 301, so that the bottom of the support plate 301 contacts the ground. At this time, a triangular support structure is formed between the support rods 302 and the push rod 303, greatly improving the support effect and stability of the device.

[0023] The sliding component 60 includes: mounting plates 601, and two symmetrically arranged mounting plates 601 are fixedly installed at the rear of the bottom surface of the machine case 10; a screw rod 602, and the screw rod 602 is rotatably installed between the two mounting plates 601; a slider 603, and the slider 603 is threadedly fitted on the screw rod 602. The screw rod 602 longitudinally penetrates through the slider 603 and is threadedly fitted with it. The upper end of the push rod 303 is hinged to the lower end of the slider 603; an adjusting component 70 capable of driving the screw rod 602 to rotate is provided at the back of the machine case 10.

[0024] When it is necessary to adjust the support assembly 30 to stably place the oxygen inhaler, the adjusting assembly 70 drives the screw rod 602 to rotate. Since the screw rod 602 is in threaded engagement with the slider 603, when the screw rod 602 rotates, the slider 603 will move axially along the screw rod 602. The movement of the slider 603 drives the push rod 303 hinged thereto to swing up and down. The swing of the push rod 303 pushes the support plate 301 to move downward. At the same time, the support rod 302 follows the support plate 301 to swing downward until the bottom of the support plate 301 contacts the ground, forming a stable triangular support structure. When it is necessary to move the device, the adjusting assembly 70 is operated in reverse, so that the slider 603 drives the push rod 303 to swing upward, the support plate 301 rises away from the ground, and the device returns to a movable state. The sliding assembly 60 realizes precise adjustment of the support assembly 30 through the threaded transmission between the screw rod 602 and the slider 603. Medical staff only need to simply operate the adjusting assembly 70 to easily control the deployment and retraction of the support assembly 30, provide stable support during the use of the device, avoid tipping, and ensure the use safety; when moving the device, the support structure can be quickly retracted without affecting the flexible movement of the device, improving the convenience and stability of the device use.

[0025] The adjusting assembly 70 includes: a bushing 701, which is fixedly installed on the rear of the machine shell 10; a transmission rod 702, which vertically penetrates the bushing 701 and is connected thereto by a bearing; a first bevel gear 703, which is fixedly installed at the lower end of the transmission rod 702; a second bevel gear 704, the screw rod 602 penetrates the rear mounting plate 601 and is connected thereto by a bearing, and a second bevel gear 704 meshing with the first bevel gear 703 is fixedly installed at the rear end of the screw rod 602; a gear 705, which is fixedly installed at the upper end of the transmission rod 702; a housing 706, which is fixedly installed on the rear of the machine shell 10, the gear 705 is located inside the housing 706, the transmission rod 702 vertically penetrates the bottom of the housing 706 and is connected thereto by a bearing, and a rectangular opening is formed in the rear of the housing 706; a rack 708, which is slidably installed in the opening at the rear of the housing 706 and meshes with the gear 705, chutes are respectively formed on the upper and lower surfaces of the rack 708, and the rack 708 is matched with the rectangular opening at the rear of the housing 706 through the chutes; a handle 709, which is fixedly installed on the rear of the rack 708.

[0026] When the medical staff pulls the handle 709, the rack 708 slides in the opening behind the housing 706. Since the rack 708 is meshed with the gear 705, the sliding of the rack 708 drives the gear 705 to rotate. The gear 705 is fixedly mounted on the transmission rod 702, thereby rotating the transmission rod 702. The first bevel gear 703 at the lower end of the transmission rod 702 is meshed with the second bevel gear 704 at the rear end of the screw 602. The rotation of the transmission rod 702 drives the screw 602 to rotate through the transmission of the first bevel gear 703 and the second bevel gear 704, thereby realizing the movement of the slider 603 in the position sliding assembly 60, and finally controlling the state of the support assembly 30.

[0027] Two elastic clamps 80 arranged opposite to each other are fixedly installed in the middle of the rear of the receiving groove 102. When the humidification bottle 40 is inserted into the receiving groove 102, the humidification bottle 40 squeezes the two elastic clamps 80 arranged opposite to each other, and the elastic clamps 80 are elastically deformed. When the humidification bottle 40 reaches the appropriate position, the elastic clamps 80 return to their original state by virtue of their own elasticity, tightly clamp the humidification bottle 40, and firmly fix it in the receiving groove 102. When it is necessary to take out the humidification bottle 40, the elastic clamps 80 are manually opened to separate them from the humidification bottle 40, and the humidification bottle 40 can be easily taken out.

[0028] The elastic clamp 80 is an arc-shaped structure. When the elastic clamp 80 with an arc-shaped structure contacts the humidification bottle 40, it can better fit the outer surface contour of the humidification bottle 40. When the elastic clamp 80 clamps the humidification bottle 40, the arc-shaped design makes the contact area between the two larger and the pressure distribution more uniform, thereby providing a more stable fixing effect. Compared with a non-arc-shaped structure, when the arc-shaped elastic clamp 80 is subjected to force, the force transmission is more reasonable, and local stress concentration is not likely to occur, thereby ensuring the elastic performance and service life of the elastic clamp 80 itself.

[0029] An electric heating plate 90 is provided at the bottom of the receiving tank 102. The electric heating plate 90 starts to work after being powered on and generates heat. The heat is transferred to the humidification bottle 40 in the receiving tank 102, and the liquid in the humidification bottle 40 is heated to increase the temperature of the liquid. In a cold environment or when the patient has special requirements for the temperature of the inhaled oxygen, the temperature of the liquid in the humidification bottle 40 can be adjusted by controlling the heating power and time of the electric heating plate 90, so that the output oxygen reaches a suitable temperature; and the heating can promote the evaporation of the water in the humidification bottle 40, ensure the humidity of the oxygen, and prevent the patient from being too dry when inhaling oxygen.

[0030] The oxygen production assembly 20 comprises: The compressor is a high-quality oil-free piston air compressor, which is fixedly installed at the lower part of the casing and is used to compress the air at a high density to provide power for the subsequent oxygen production process; A filter is provided at the left end of the compressor and screwed thereto, capable of removing most impurities such as oil, water, dust, etc. in the compressed air; A molecular sieve, using a new type of high-efficiency lithium-based molecular sieve, is installed on the left side of the separation valve and fixedly connected thereto. Based on the principle of pressure adsorption and pressure reduction desorption, and due to the difference in the adsorption capacity for oxygen and nitrogen, it adsorbs nitrogen in the air and separates oxygen; A separation valve is connected to the output end of the compressor and is used to cooperate with the molecular sieve to achieve the separation operation of air components; The connecting pipe 201 is fixedly connected to the exhaust port of the molecular sieve, used to collect the oxygen separated by the molecular sieve and transport the oxygen to the inlet of the humidifying bottle 40.

[0031] After the compressor starts, it compresses air at high density. The compressed air enters the filter, and the filter removes most of the impurities such as oil, water, dust, etc. in it. The filtered air enters the separation valve, and with the cooperation of the separation valve, the air enters the molecular sieve. The molecular sieve uses the principle of pressure adsorption and pressure reduction desorption. Based on the difference in the adsorption capacity for oxygen and nitrogen, it adsorbs nitrogen in the air under pressure and separates oxygen. The separated oxygen is transported from the exhaust port of the molecular sieve to the inlet of the humidifying bottle 40 through the connecting pipe 201 for subsequent humidification and inhalation by the patient. Each component in the oxygen generation assembly 20 has a clear division of labor and works together to achieve an efficient oxygen generation process. The high-quality oil-free piston air compressor provides stable compression power. The filter ensures the cleanliness of the air entering the molecular sieve, reduces the impact of impurities on the performance of the molecular sieve, and extends the service life of the molecular sieve. The new type of high-efficiency lithium-based molecular sieve has excellent oxygen separation ability and can stably separate high-purity oxygen. The design of this oxygen generation assembly 20 enables the oxygen inhaler to generate oxygen independently without relying on external oxygen cylinders, reducing the use cost and dependence on external supply. At the same time, the stable oxygen generation performance ensures that patients can continuously obtain sufficient and high-quality oxygen, improving the treatment effect and patient safety.
