Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a safety oxygen flow meter. Background Technology

[0002] Oxygen therapy is one of the most common clinical treatments. However, different types of hypoxia require different oxygen flow rates. For example, type I respiratory failure requires high-flow oxygen therapy, while type II respiratory failure requires low-flow oxygen therapy. Therefore, an oxygen flow meter is needed to adjust the oxygen flow rate during oxygen therapy so that the patient can receive oxygen effectively.

[0003] Existing oxygen flow meters work by turning an adjustment knob, which causes oxygen to flow through the meter and lift a float inside. The scale above the float indicates the oxygen flow rate per minute. Adjusting the float to the appropriate position is problematic because the adjustment knob is flexible. After medical staff have finished adjusting the flow meter, some patients may disregard their advice and adjust it arbitrarily, potentially leading to excessively high or low oxygen concentrations and posing a safety risk. Therefore, to address these issues, we propose a safer oxygen flow meter. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a safe oxygen flow meter with a simple locking mechanism for the adjustment knob, preventing patients from adjusting it themselves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety oxygen flow meter, comprising a flow meter body and an adjusting component. An adjusting knob is rotatably connected to the flow meter body. The adjusting knob is used to adjust the oxygen flow rate according to different types of hypoxia. A groove is provided on the adjusting knob, and a sliding plate is slidably connected within the groove. The adjusting component includes at least two rotating rings rotatably connected to the adjusting knob and notches on the rotating rings. Multiple grooves corresponding to the rotating rings are provided on the sliding plate. The width of the rotating rings and the width of the sliding plate are respectively smaller than the width of the grooves and the width of the notches. An adjusting ring is provided on the outer wall of the rotating rings. Multiple slots are equidistantly provided on the outer wall of the adjusting rings. A rod is provided at one end of the sliding plate near the flow meter body. Multiple insertion holes adapted to the rod are provided on the flow meter body, and the multiple insertion holes are equidistantly arranged along the central axis of the adjusting knob.

[0006] The beneficial effects of this utility model are as follows: by setting different symbols in the empty slot, rotating the adjustment ring controls the rotation of the rotating ring, so that the notch is misaligned among multiple rotating rings, fixing the position of the slide plate, thereby inserting the insertion rod into the corresponding insertion hole, fixing the adjustment knob, and the unlocking symbol is confidential to the patient, thus preventing the patient from adjusting the oxygen flow rate by himself.

[0007] To facilitate unlocking the adjustment knob;

[0008] As a further improvement to the above technical solution: a spring is connected between the sliding plate and the flow meter body.

[0009] The beneficial effects of this improvement are as follows: when different adjustment rings are rotated, the symbol corresponding to the notch on each ring is rotated to the same horizontal line as the slide plate. At this time, under the elastic action of the spring, the slide plate slides away from the insertion rod through multiple notches inside the slide groove. At the same time, the insertion rod moves away from the insertion hole, releasing the locking of the adjustment knob. The adjustment knob can then continue to be adjusted appropriately according to the patient's hypoxia.

[0010] To allow the slide to return to its original position, it is easier to fix the insert rod in the socket;

[0011] As a further improvement to the above technical solution: a limiting part is provided at the end of the slide away from the insertion rod.

[0012] The beneficial effects of this improvement are as follows: After the oxygen flow rate adjustment is completed, the push limit part drives the slide plate to reset. When the limit part touches the adjustment ring, the slide plate cannot be pushed any further. At this time, the position of the rotating ring corresponds to the groove, and the insertion rod is inserted into the insertion hole. Then, the adjustment ring is rotated freely so that the position of the rotating ring without the notch is stuck in the groove, thereby fixing the insertion rod in the insertion hole.

[0013] To protect the insertion rod;

[0014] As a further improvement to the above technical solution: the flow meter body is provided with a protective ring, which is rotatably connected to the adjusting ring.

[0015] The beneficial effects of this improvement are: after the insertion rod is inserted into the insertion hole, the protective ring shields the insertion rod, preventing the patient from touching the insertion rod at will and avoiding damage caused by external force.

[0016] To protect the skateboard;

[0017] As a further improvement to the above technical solution: a protective pad is provided at the end of the chute away from the flow meter body.

[0018] The beneficial effects of this improvement are as follows: when the skateboard pops out under the elastic action of the spring, it will come into contact with the inner wall of the slide groove. At this time, the skateboard will collide with the inner wall of the slide groove. The protective pad can avoid the damage caused by the collision between the two and increase the protection of the skateboard.

[0019] To facilitate insertion of the plug into the socket;

[0020] As a further improvement to the above technical solution: the end of the insertion rod away from the slide plate is provided with a pointed head.

[0021] The beneficial effects of this improvement are: the pointed tip reduces the initial resistance when inserting the plug into the socket, improves the convenience and efficiency of inserting the plug into the socket, and makes the insertion process more accurate and smooth.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0030] like Figure 1-6As shown, a safety oxygen flow meter includes a flow meter body 1 and an adjusting component. An adjusting knob 2 is rotatably connected to the flow meter body 1. The adjusting knob 2 is used to adjust the oxygen flow rate according to different types of hypoxia. A groove 3 is provided on the adjusting knob 2, and a sliding plate 4 is slidably connected within the groove 3. The adjusting component includes at least two rotating rings 501 rotatably connected to the adjusting knob 2 and notches 502 formed on the rotating rings 501. Multiple grooves 6 corresponding to the rotating rings 501 are formed on the sliding plate 4. The width of the rotating rings 501 and the width of the sliding plate 4 are smaller than the width of the grooves 6 and the width of the notches 502, respectively. An adjusting ring 7 is provided on the outer wall of the rotating rings 501, and multiple slots 8 are equidistantly formed on the outer wall of the adjusting ring 7. A rod 9 is provided at one end of the sliding plate 4 near the flow meter body 1. Multiple insertion holes 10 adapted to the rod 9 are formed on the flow meter body 1, and the multiple insertion holes 10 are equidistantly arranged along the central axis of the adjusting knob 2.

[0031] Specifically, different symbols, numbers, or letters can be set inside the slots 8 on each adjusting ring 7. While the symbols, numbers, or letters on two or more adjusting rings 7 may be identical, the symbols, numbers, or letters corresponding to the notches 502 on the rotating rings 501 of each adjusting ring 7 are different. For example, different numbers might be set; the notch 502 on the first rotating ring 501 might correspond to the number two, and the notch 502 on the second rotating ring 501 might correspond to the number five. When adjusting the adjusting knob 2, observe the position of the slide plate 4 from the slide groove 3, and then rotate the adjusting ring 7 to move the corresponding number to the position of the slide plate 4. When all the notches 502 are aligned with the slide plate 4, pull out the slide plate 4. At this time, the insertion rod 9 disengages from the socket 10, allowing the adjustment knob 2 to be rotated. After adjustment, push the slide plate 4 back to its original position. At this time, the groove 6 corresponds to the rotating ring 501, and the insertion rod 9 is inserted into the socket 10. Then, rotate the adjustment ring 7 randomly to fix the insertion rod 9 in the socket 10, preventing further rotation of the adjustment knob 2. The symbols, numbers, or letters corresponding to the notches 502 on each rotating ring 501 are known only to medical staff and not to the patient. Therefore, once the medical staff adjusts the oxygen flow to a fixed position, the patient cannot adjust it themselves, increasing the safety of oxygen use.

[0032] Preferably, a spring 11 connects the slide plate 4 to the flow meter body 1. When different adjusting rings 7 are rotated, the symbol corresponding to the notch 502 on each rotating ring 501 is rotated to the same horizontal line as the slide plate 4. At this time, under the elastic action of the spring 11, the slide plate 4 slides away from the insertion rod 9 through multiple notches 502 inside the slide groove 3. At the same time, the insertion rod 9 moves away from the insertion hole 10, releasing the locking of the adjusting knob 2. Then, the adjusting knob 2 drives the rotating ring 501 and the adjusting ring 7 to rotate. The adjusting knob 2 continues to make appropriate adjustments according to the patient's hypoxia.

[0033] Preferably, the end of the slide plate 4 away from the insertion rod 9 is provided with a limiting part 12. After the oxygen flow rate adjustment is completed, the limiting part 12 is pushed to drive the slide plate 4 to reset. When the limiting part 12 touches the adjusting ring 7, the slide plate 4 cannot be pushed any further. At this time, the position of the rotating ring 501 corresponds to that of the groove 6, and the insertion rod 9 is inserted into the insertion hole 10. Then, the adjusting ring 7 is rotated at will so that the position of the rotating ring 501 without the notch 502 is stuck in the groove 6, thereby fixing the insertion rod 9 in the insertion hole 10.

[0034] Preferably, the flow meter body 1 is provided with a protective ring 13, which is rotatably connected to the adjusting ring 7. After the insertion rod 9 is inserted into the insertion hole 10, the protective ring 13 shields the insertion rod 9 to prevent the patient from touching the insertion rod 9 at will and to prevent damage caused by external force.

[0035] Preferably, a protective pad 14 is provided at the end of the slide groove 3 away from the flow meter body 1. The protective pad 14 is made of rubber, silicone or other materials. When the slide plate 4 pops out under the elastic action of the spring 11, the slide plate 4 will come into contact with the inner wall of the slide groove 3. At this time, the slide plate 4 will collide with the inner wall of the slide groove 3. The setting of the protective pad 14 can avoid the damage caused by the collision between the two and increase the protection of the slide plate 4.

[0036] Preferably, the end of the insertion rod 9 away from the slide plate 4 is provided with a pointed head 15. The pointed head 15 reduces the initial resistance when the insertion rod 9 is inserted into the insertion hole 10, improves the convenience and efficiency of inserting the insertion rod 9 into the insertion hole 10, and makes the insertion process more accurate and smooth.

[0037] The working principle and usage process of this utility model are as follows: When using this device, first turn the adjustment knob 2 to adjust the oxygen flow rate. After adjustment, push the limiting part 12. When the limiting part 12 contacts the adjustment ring 7, the slide plate 4 slides inside the slide groove 3 and squeezes the spring 11, inserting the rod 9 into the corresponding insertion hole 10. Then, the groove 6 corresponds to the rotating ring 501. Then, the medical staff directly rotates the adjustment ring 7 randomly, so that the rotating ring 501 is inserted into the groove 6, and the rod 9 is fixed inside the insertion hole 10. Then, when it is necessary to adjust the oxygen flow rate again, the medical staff will... Knowing the symbol in the slot 8 corresponding to each notch 502, and then observing the position of the slide plate 4, rotate the adjusting ring 7 to rotate the corresponding slot 8 to the position of the slide plate 4, so that all notches 502 and slide plate 4 are on the same horizontal line. At this time, under the elastic action of spring 11, slide plate 4 slides in the notch 502 toward the protective pad 14 and contacts the protective pad 14. At this time, groove 6 is misaligned with rotating ring 501, and adjustment knob 2 can be directly rotated for adjustment. When using this utility model, it can prevent patients from arbitrarily adjusting the oxygen flow rate, thus increasing the safety of oxygen use.
