Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an integrated uninterrupted oxygen delivery device. Background Technology

[0002] In actual medical practice, some patients require oxygen-assisted therapy. Wall-mounted oxygen inhalers, as terminal equipment in hospital central oxygen supply systems, are commonly used devices for oxygen therapy. Their core function is to deliver high-pressure oxygen to patients at a set flow rate after depressurization and humidification. This device, fixed to the wall, connects directly to the hospital's low-pressure oxygen supply pipeline, offering advantages such as stable air supply, convenient operation, and low maintenance costs. It is widely used in emergency resuscitation, postoperative recovery, and oxygen therapy for chronic diseases. However, due to varying patient conditions, it is often necessary to switch between low-flow nasal oxygen delivery via an oxygen inhaler and high-flow oxygen delivery via a breathing bag.

[0003] Existing wall-mounted oxygen inhalers often have only a single oxygen output port. When switching oxygen delivery modes, the patient's oxygen supply is briefly interrupted. During continuous supply, the flow rate adjustment knob needs to be rotated to control the oxygen output rate. However, since the flow rate adjustment knob is exposed outside the device, patients and their families may accidentally touch it, causing changes in the oxygen output rate, which may harm the patient's health. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated uninterrupted oxygen delivery device, which aims to improve the problem that the flow adjustment knob of the existing oxygen delivery device is easily touched by the patient, which leads to changes in the oxygen output rate and thus endangers the patient's health.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated uninterrupted oxygen delivery device, comprising a humidification bottle, a communicating vessel at the top of the humidification bottle, a rotating sleeve rotatably connected to the inner wall of the communicating vessel, a turntable fixedly connected to the inner wall of the rotating sleeve, a limiting sleeve fixedly connected to the outer wall of the turntable, a spring sleeved on the outer wall of the limiting sleeve, a sliding rod movably connected to the inner wall of the limiting sleeve, a gear fixedly connected to the outer wall of the sliding rod, an adjusting knob fixedly connected to the outer wall of the gear, a toothed ring fixedly connected to the outer wall of the rotating sleeve, and an oxygen output switching component disposed inside the communicating vessel.

[0006] Preferably, the oxygen output switching component includes a three-way tube, which is disposed on the inner wall of the communicating vessel. One end of the three-way tube is provided with an air inlet connector, and both ends of the three-way tube are provided with oxygen storage cylinders. One end of one of the oxygen storage cylinders is provided with a nasal oxygen outlet, and one end of the oxygen storage cylinder is provided with a breathing bag oxygen outlet. The communicating vessel is provided with an atomizing port inside.

[0007] Preferably, the humidification bottle is provided with a humidification tube and distilled water inside, and the humidification tube is connected to a communicating vessel.

[0008] Preferably, the top of the communicating vessel is provided with a flow tube, the inside of the flow tube is provided with a float tube, the outer wall of the float tube is provided with scale lines, the float tube and the communicating vessel are connected, and a float is slidably connected to the inner wall of the float tube.

[0009] Preferably, the other end of the rotating sleeve is provided with a flow regulating valve body, which is located inside the communicating vessel.

[0010] Preferably, the gear is slidably connected to the inner wall of the gear ring, and the ends of the gear and the gear ring mesh with each other.

[0011] Preferably, the inner wall of the oxygen storage cylinder is provided with a one-way valve.

[0012] Preferably, the three-way pipe, the humidification pipe, and the float pipe are interconnected.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a rotating sleeve is fixedly connected to the outer wall of a traditional flow regulating valve. By pressing the adjustment knob, the gear and slide bar are driven to compress the spring and mesh with the gear ring. Then, by rotating the adjustment knob, the gear ring and rotating sleeve are driven to rotate, thereby driving the valve body to control the oxygen flow rate, preventing patients from accidentally touching the oxygen flow regulating valve and ensuring the safety of the patient's oxygen delivery process.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figures 1-3 An embodiment of this utility model provides an integrated uninterrupted oxygen supply device, comprising a humidification bottle 1, a communicating vessel 2 at the top of the humidification bottle 1, a rotating sleeve 4 rotatably connected to the inner wall of the communicating vessel 2, a turntable 5 fixedly connected to the inner wall of the rotating sleeve 4, a limiting sleeve 6 fixedly connected to the outer wall of the turntable 5, a spring 7 sleeved on the outer wall of the limiting sleeve 6, a sliding rod 8 movably connected to the inner wall of the limiting sleeve 6, a gear 9 fixedly connected to the outer wall of the sliding rod 8, an adjusting knob 10 fixedly connected to the outer wall of the gear 9, a gear ring 11 fixedly connected to the outer wall of the rotating sleeve 4, an oxygen output switching component inside the communicating vessel 2, a flow regulating valve body at the other end of the rotating sleeve 4, the valve body being located inside the communicating vessel 2, the gear 9 being slidably connected to the inner wall of the gear ring 11, and the teeth of the gear 9 and the gear ring 11 meshing with each other.

[0019] Specifically, the various components are connected through the communicating vessel 2. A rotating sleeve 4 is fixedly connected to the flow control valve body inside the conventional communicating vessel 2. The rotating sleeve 4 controls the rotation and adjustment of the valve body. When oxygen flow adjustment is required, the adjusting knob 10 needs to be pressed first. The gear 9 fixed on the outer wall of the adjusting knob 10 slides with the adjusting knob 10. The slide rod 8 fixed on the outer wall of the gear 9 moves with the gear 9. The limiting sleeve 6 limits the movement of the gear 9. When the gear 9 slides, its outer wall will compress the spring 7 until it meshes with the gear ring 11. At this time, the adjusting knob 10 can be rotated to drive the gear 9, which in turn drives the gear ring 11 to rotate. The gear ring 11 drives the rotating sleeve 4 to rotate through the fixed connection. Then, the internal control valve body can be driven to control the flow. The stress of the spring 7 ensures the rebound of the device, which is convenient for subsequent use.

[0020] Reference Figure 1 and Figure 5 The oxygen output switching component includes a three-way tube 12, which is located on the inner wall of the communicating vessel 2. One end of the three-way tube 12 is provided with an air inlet connector 13, and both ends of the three-way tube 12 are provided with oxygen storage cylinders 14. One end of one oxygen storage cylinder 14 is provided with a nasal oxygen outlet 15, and one end of another oxygen storage cylinder 14 is provided with a breathing bag oxygen outlet 16. The communicating vessel 2 is provided with a nebulizer port 17. The three-way tube 12, the humidification tube 18, and the float tube 20 are interconnected.

[0021] Specifically, when oxygen enters from 13 into 12, the oxygen output mode is controlled by the valve body. The other two ends are connected to 15 and 16 via 14, respectively, allowing medical staff to switch the oxygen output mode in real time to meet the oxygen delivery needs in different situations. 17 is also provided on the inner wall of 2 to meet the nebulization needs of patients.

[0022] Reference Figure 4 The humidification bottle 1 is equipped with a humidification tube 18 and distilled water 19 inside, and the humidification tube 18 is connected to the communicating vessel 2.

[0023] Specifically, oxygen enters the humidification bottle 1 through the humidification tube 18, is humidified by distilled water 19, and then returns to the communicating vessel 2 before being output to the patient, thereby humidifying the dry oxygen and reducing irritation to the respiratory tract.

[0024] Reference Figure 4 The top of the communicating vessel 2 is provided with a flow tube 3, and the inside of the flow tube 3 is provided with a float tube 20. The outer wall of the float tube 20 is provided with scale lines. The float tube 20 and the communicating vessel 2 are connected. The inner wall of the float tube 20 is slidably connected with a float 21.

[0025] Specifically, when oxygen enters the communicating vessel 2, due to buoyancy, the oxygen will cause the float 21 to float and slide within the float tube 20, allowing personnel to observe the rate and flow of oxygen through the scale lines.

[0026] Reference Figure 6 The inner wall of the oxygen storage cylinder 14 is equipped with a one-way valve 22.

[0027] Specifically, when oxygen enters the nasal cavity outlet 15 or the breathing bag outlet 16 through the oxygen storage cylinder 14, it is blocked by the one-way valve 22 to prevent oxygen backflow and fill the oxygen storage cylinder 14. When the output mode is switched, the oxygen in the oxygen storage cylinder 14 will temporarily supply oxygen to the patient, thereby achieving the effect of uninterrupted oxygen supply when switching.

[0028] Working principle: When using this oxygen delivery device, connect the air inlet connector 13 to the hospital's oxygen supply pipeline. Oxygen enters the three-way tube 12 through the air inlet connector 13, then enters the humidification bottle 1 through the humidification tube 18, is moistened by distilled water 19, and then returns to the communicating vessel 2. It first enters the oxygen storage bottle 14 to store a portion, and then, depending on the actual needs, controls the valve body of the three-way tube 12 to deliver oxygen from the nasal cavity oxygen outlet 15 or the breathing bag oxygen outlet 16 for the patient's use. During the oxygen flow, the float 21 in the float tube 20 is raised to observe the flow rate, and the real-time oxygen flow rate is adjusted by pressing and rotating the adjustment knob 10.

[0029] When switching oxygen delivery modes, the oxygen storage cylinder 14 will store a portion of oxygen due to the one-way valve 22, which will temporarily meet the patient's oxygen needs during the switching phase, thereby achieving uninterrupted oxygen delivery.

[0030] To prevent patients and accompanying family members from accidentally touching the adjustment knob 10, which could alter the oxygen supply flow and endanger patient safety, when adjusting the flow, the adjustment knob 10 must first be pressed, causing the gear 9 to compress the spring 7 and slide along the inner wall of the limiting sleeve 6. After the gear 9 meshes with the gear ring 11, the adjustment knob 10 is rotated, causing the gear ring 11 to rotate, which in turn causes the rotating sleeve 4 to rotate, thereby rotating the internal valve body to achieve the effect of flow adjustment. Rotating the adjustment knob 10 alone will only rotate the slide bar 8 and will not affect the valve body, thus not affecting the oxygen output flow.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
