Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen delivery equipment, and in particular relates to a portable oxygen delivery device. Background Art

[0002] Portable oxygen supply devices often use oxygen bags as oxygen sources. The pressure in the oxygen bag gradually decreases when the oxygen bag outputs oxygen, so continuous and effective oxygen supply cannot be achieved. Currently, manual pressing is often used to make the oxygen bag continuously output oxygen. Medical staff are required to press the oxygen bag to maintain a certain pressure to discharge oxygen, but manual operation is time-consuming and laborious. In addition, medical staff cannot adjust the size of the oxygen flow rate. Too large a flow rate can easily cause a waste of oxygen, and too small a flow rate can fail to achieve the purpose of oxygen inhalation. Utility Model Content

[0010] Preferably, a first slide bar that slides through the slide plate is fixedly connected to one side of the fixed seat, a first baffle plate is fixedly connected to one end of the first slide bar, a first spring is fixedly connected between the first baffle plate and the slide plate, and the first spring is sleeved on the outside of the first slide bar.

[0011] Preferably, an air inlet pipe and an air outlet pipe are passed through the top of the humidifier bottle, and the ends of the air outlet pipe and the air inlet pipe extending into the humidifier bottle are respectively located on the upper and lower sides of the liquid surface in the humidifier bottle, a hose is connected between the other end of the air outlet pipe and the nasal catheter, and the other end of the air inlet pipe is connected to the air outlet of the oxygen bag.

[0014] Preferably, an adjusting bolt is screwed through the top of the air inlet pipe, and the bottom of the adjusting bolt is rotatably connected to the top of the slide.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The utility model is provided with a pressurizing mechanism, which drives the fixed seat to move by sliding the slide plate in the slide groove, thereby moving one end of the first strap, so that the first strap and the second strap automatically pressurize the oxygen bag, so that oxygen can be continuously discharged for continuous oxygen supply.

The elastic force of the second spring causes the second baffle to drive the second slide rod to push the sealing block against the slide. The trumpet-shaped inner wall of the slide and the truncated cone outer wall of the sealing block cooperate to allow oxygen to move in only one direction, thereby preventing the liquid in the humidifier bottle from flowing back into the oxygen bag and causing losses.

[0019] (4) The utility model is provided with an adjusting screw, and the slide is made to slide in the air intake pipe by rotating the adjusting bolt, so as to adjust the distance between the slide and the fixed frame, thereby changing the initial stretching amount of the second spring, thereby reducing the stretchable length of the second spring, and changing the maximum distance that the sealing block moves relative to the slide, thereby controlling the maximum gap between the sealing block and the slide, and thus controlling the flow rate of oxygen.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions:

[0029] A portable oxygen supply device comprises a box body 1 and a box cover 2 rotatably connected to the box body 1, a humidifying bottle 10 for humidifying oxygen and a nasal catheter 8 for connecting a pen hole are arranged on the box body 1, a slide groove 13 is arranged at the bottom of the box body 1, a through hole 14 connected to the slide groove 13 is arranged on the box body 1, a slide plate 21 is slidably connected in the slide groove 13, a fixing seat 20 is arranged on one side of the slide plate 21, an oxygen bag 4 and a pressurizing mechanism sleeved on the outside of the oxygen bag 4 are arranged in the box body 1, the pressurizing mechanism comprises a first strap 3 and a second strap 5 connected at one end, the other end of the first strap 3 passes through the through hole 14 and is fixedly connected to the fixing seat 20, and the other end of the second strap 5 is fixedly connected to the box body 1; Velcro is fixed at one end of the first strap 3 and the second strap 5, and the two Velcros fit each other.

[0030] Based on the above disclosed structure, when performing oxygen delivery operation:

[0031] First, the oxygen bag 4 is placed in the box body 1, and then one end of the first strap 3 and the second strap 5 are adhered by Velcro, and the first strap 3 and the second strap 5 are sleeved on the outside of the oxygen bag 4, and then the nasal catheter 8 is inserted into the patient's nose, and then the slide plate 21 is slid in the slide groove 13, so that the slide plate 21 drives the fixing seat 20 to move in the direction away from the through hole 14, thereby driving one end of the first strap 3 to move, so that the space surrounded by the first strap 3 and the second strap 5 and the box body 1 is reduced, so that the first strap 3 and the second strap 5 pressurize the oxygen bag 4, so that the air in the oxygen bag 4 is discharged from the air outlet of the oxygen bag 4, and then the oxygen is humidified through the humidification bottle 10, and finally introduced into the patient's body through the nasal catheter 8. The sliding of the slide plate 21 can keep the first strap 3 in a taut state at all times, so that the oxygen bag can be continuously pressurized, thereby realizing continuous oxygen supply, and the operation is simple.

[0032] Preferably, a guide roller 19 is rotatably connected to one side of the through hole 14 in the box body 1, and the first strap 3 is sleeved on the outside of the guide roller 19. Based on this, when the first strap 3 passes through the through hole 14, it contacts and rolls relative to the guide roller 19, thereby reducing the friction on the first strap 3 and extending its service life.

[0033] As mentioned above, regarding the sliding of the slide plate 21, it is preferred to have the following structure:

[0034] Two guide rods 18 are symmetrically fixed in the slide groove 13, and the slide plate 21 is slidably connected between the two guide rods 18. A screw rod 22 that is screwed through the slide plate 21 is rotatably connected to the box body 1;

[0035] A worm 23 is rotatably connected to the housing 1, a worm gear 24 is coaxially fixed to one end of the screw 22, the worm gear 24 and the worm gear 23 are meshed for transmission, and a hand wheel 7 is fixed to the top of the worm gear 23;

[0036] A first slide bar 16 that slides through the slide plate 21 is fixedly connected to one side of the fixed seat 20, and a first baffle 15 is fixedly connected to one end of the first slide bar 16. A first spring 17 is fixedly connected between the first baffle 15 and the slide plate 21, and the first spring 17 is sleeved on the outside of the first slide bar 16.

[0037] As can be seen from the above, the hand wheel 7 is rotated from the box body 1 to rotate the worm 23, and the worm 23 and the turbine 24 are meshed for transmission, so that the turbine 24 drives the screw rod 22 to rotate, so that the screw-connected slide plate 21 slides in the slide groove 13, and the two guide rods 18 can ensure the smooth movement of the slide plate 21 to prevent the slide plate 21 from tilting. The slide plate 21 drives the first baffle 15 to move through the first spring 17, so that the first slide bar 16 drives the fixed seat 20 to move. When the fixed seat 20 pulls and tightens the first strap 3, the hand wheel 7 is continued to be rotated to make the slide plate 21 continue to move. The slide plate 21 compresses the first spring 17, so that the first spring 17 stores a certain elastic force. Then, during the oxygen delivery process, as the volume of the oxygen bag 4 decreases, the fixed seat 20 drives one end of the first strap 3 to move based on the elastic force of the first spring 17, so that the pressurized structure can continuously apply pressure to the oxygen bag 4 to ensure the continuous output of oxygen, and the medical staff only need to intermittently rotate the hand wheel 7 to move the slide plate 21, which is simple to operate and has low work intensity.

[0038] In addition, the humidifying bottle 10 is preferably provided with the following structure:

[0039] An air inlet pipe 6 and an air outlet pipe 11 are passed through the top of the humidifying bottle 10. The ends of the air outlet pipe 11 and the air inlet pipe 6 extending into the humidifying bottle 10 are respectively located at the upper and lower sides of the liquid surface in the humidifying bottle 10. A hose 9 is connected between the other end of the air outlet pipe 11 and the nasal catheter 8. The other end of the air inlet pipe 6 is connected to the air outlet of the oxygen bag 4.

[0040] A fixing frame 27 is fixedly connected in the air intake pipe 6, a slide frame 25 is provided in the air intake pipe 6, a sealing block 26 is slidably connected in the slide frame 25, a second slide bar 29 that slides through the fixing frame 27 is fixedly connected at the bottom of the sealing block 26, a second baffle plate 28 is fixedly installed at the bottom of the second slide bar 29, a second spring 30 is connected between the second baffle plate 28 and the fixing frame 27, and the second spring 30 is sleeved on the outside of the second slide bar 29;

[0041] The sealing block 26 is a truncated cone structure, the bottom of the slide 25 is a trumpet-shaped structure, and the circumferential inclined surface of the sealing block 26 matches the inner wall of the slide 25 .

[0042] As can be seen from the above, after the oxygen is discharged from the oxygen bag 4, it enters the air inlet pipe 6, and under the action of the gas pressure, the sealing block 26 is pushed to separate from the slide 25, so that the trumpet-shaped inner wall of the slide 25 and the truncated cone-shaped outer wall of the sealing block 26 are separated to generate a gap, allowing the oxygen to pass through. At the same time, the sealing block 26 pushes the second baffle 28 away from the fixing frame 27 through the second slide bar 29, so that the second baffle 28 stretches the second spring 30. After the oxygen passes through and the subsequent oxygen pressure is insufficient, under the elastic force of the second spring 30, the second baffle 28 drives the sealing block 26 through the second slide bar 29 to approach and contact the slide 25, and the air inlet pipe 6 is closed, so as to prevent the liquid in the humidification bottle 10 from flowing back into the oxygen bag 4 through the air inlet pipe 6, causing the oxygen bag 4 to be damaged;

[0043] Then, oxygen is passed from the bottom end of the air inlet pipe 6 into the liquid level in the humidification bottle 10, and oxygen bubbles rise. At the same time, the liquid in the humidification bottle 10 humidifies the oxygen to prevent dry oxygen from being directly input into the human body and causing damage. Then, oxygen is input into the hose 9 from the air outlet pipe 11, and finally input into the patient's body through the nasal catheter 8.

[0044] Furthermore, in order to adjust the flow rate of oxygen, an adjusting bolt 12 is screwed through the top of the air inlet pipe 6 , and the bottom of the adjusting bolt 12 is rotatably connected to the top of the slide 25 . Based on this, the adjusting bolt 12 is rotated so that one end of the adjusting screw 12 is screwed into the air inlet pipe 6, so that the slide 25 slides downward in the air inlet pipe 6, so that the slide 25 is close to the fixed frame 27, and the slide 25 drives the sealing block 26 to move downward, and the second slide bar 29 drives the second baffle 28 away from the fixed frame 27, and stretches the second spring 30, so that the initial length of the second spring 30 increases. Based on the fact that the maximum pressure that the oxygen in the oxygen bag 4 can reach is constant, the elastic force of the second spring 30 that the oxygen can overcome is constant, so that the maximum length that the second spring 30 can stretch is constant, so that the initial length of the second spring 30 increases, so that the length that the second spring 30 can still stretch under the oxygen pressure during oxygen delivery is reduced, thereby reducing the distance that the sealing block 26 moves, and then reducing the size of the maximum gap when the sealing block 26 is separated from the slide 25, thereby reducing the oxygen flow rate; conversely, the adjusting bolt 12 is rotated to make the adjusting screw 12 unscrewed from the air inlet pipe 6, so that the initial length of the second spring 30 is reduced, so that the maximum gap when the sealing block 26 is separated from the slide 25 is increased, thereby increasing the oxygen flow rate.
