Description

Technical Field

[0001] This utility model relates to the field of oxygen supply technology for wards, specifically a humidification bottle control valve reset device for wards. Background Technology

[0002] The oxygen humidifier bottle is a rehabilitation device and ward nursing consumable, mainly used in medical central oxygen supply systems. It can supply oxygen to medical units for emergency oxygen supply and oxygen inhalation for hypoxic patients. Its main function is to humidify and moisten dry oxygen. Oxygen humidifier bottles are divided into embedded and external types. When in operation, the oxygen inhaler of the oxygen humidifier bottle is mainly connected to the oxygen terminal. It can be connected to various types of plugs according to different requirements and can be connected to medical equipment belts, equipment walls, towers and other gas supply terminals. The oxygen inhaler has a precise flow rate and is convenient and safe to use. It is an essential device for oxygen therapy for patients in hospital emergency rooms and wards.

[0003] Existing hospital oxygen humidification cylinders generally have a nebulization port and an oxygen port, requiring a control valve to connect the nebulization port and the oxygen port. However, the control valve of the existing humidification cylinder does not have a reset function. After the humidification cylinder is used, the valve does not automatically reset. If the other port needs to be used next time, the valve may not reset, which may lead to oxygen leakage and potentially pose a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a humidification bottle control valve reset device for wards, which solves the problem mentioned in the background art that the existing humidification bottle control valve does not have a reset function. After the humidification bottle is used up, the valve does not automatically reset. If another port needs to be used next time, the valve may not reset, which may lead to oxygen leakage and potential safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a humidification bottle control valve reset device for wards, comprising a top cover, a humidification bottle internally threadedly connected to the top cover, a flow meter fixedly installed on the top outer wall of the top cover, a T-shaped tube fixedly connected internally to the flow meter, a crossbar slidably connected internally to the T-shaped tube, guide rods fixedly installed at both ends of the crossbar, a movable plate fixedly installed on the side of the two guide rods away from the crossbar, two springs fixedly installed internally to the T-shaped tube, two communicating cavities opened internally to the crossbar, a humidification tube and a nebulizing tube fixedly connected internally to the T-shaped tube, a piston plate slidably connected internally to the T-shaped tube, a guide tube penetrating internally to the piston plate, a stabilizing ring and a limiting ring fixedly installed internally to the T-shaped tube, a spring fixedly connected to the outer wall of the piston plate, a connecting plate fixedly installed internally to the guide tube, a sealing plate integrally formed on the outer side of the connecting plate, and an oxygen tube penetrating internally to the top cover.

[0006] Preferably, the two communicating cavities are symmetrically arranged inside the crossbar, and the two springs are fixedly connected to both ends of the crossbar.

[0007] Preferably, the outer wall of the stabilizing ring is fixedly connected to the second spring, and the second spring is disposed on the inner side of the limiting ring.

[0008] Preferably, the outer wall of the sealing plate is movably connected to the interior of the guide tube, and the guide tube is adapted to the interior of the two communicating cavities.

[0009] Preferably, two sealing rings are provided between the crossbar and the T-tube, and the two sealing rings are symmetrically arranged on the inner side of the T-tube. Two plugs are fixedly installed on the outer wall of the crossbar, and the two plugs are arranged on the inner side of the two communicating cavities.

[0010] Preferably, a sealing gasket is provided at the front end of the guide tube, and the sealing gasket is movably connected to the outer wall of the crossbar.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This ward uses a humidifier bottle control valve reset device. By connecting the flow meter to the hospital bedside equipment belt, when the patient needs oxygen supply, moving the horizontal bar to the left moves the two connecting chambers, the flow meter supplies oxygen, the pressure inside the T-tube increases, moving the piston plate, causing the guide tube inside the piston plate to insert into the connecting chamber. At this time, the horizontal bar will not move, and oxygen enters the humidifier bottle. The humidified oxygen will be discharged through the oxygen supply tube, achieving the effect of discharging humidified oxygen. When oxygen supply stops, the oxygen pressure inside the T-tube decreases, and under the action of spring two, the piston plate and guide tube will move out of the connecting chamber. At this time, the horizontal bar is no longer restricted, and under the action of spring one, it will reset, preparing for the next oxygen supply or nebulization. This solves the problem that the existing humidifier bottle control valve does not have a reset function. After the humidifier bottle is used, the valve does not automatically reset. If another port is needed for the next use, the valve may not reset, which may lead to oxygen leakage and potential safety hazards.

[0013] 2. The ward uses a humidifier bottle control valve reset device. By using a sealing ring to prevent oxygen leakage and series connection, the oxygen supplied by the guide tube can be confined between two sealing rings. Figure 4 As shown, when the connecting cavity moves, the blockage will seal the pipe on the other side, thus preventing oxygen leakage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please refer to Figures 1-8.

[0026] A humidification bottle 2 control valve reset device for wards includes a top cover 1, a humidification bottle 2 is threadedly connected to the inside of the top cover 1, a flow meter 3 is fixedly installed on the top outer wall of the top cover 1, a T-shaped tube 4 is fixedly connected inside the flow meter 3, a crossbar 5 is slidably connected inside the T-shaped tube 4, guide rods are fixedly installed at both ends of the crossbar 5, a moving plate 6 is fixedly installed on the side of the two guide rods away from the crossbar 5, two springs 7 are fixedly installed inside the T-shaped tube 4, two communicating cavities 8 are opened inside the crossbar 5, a humidification tube 9 and a nebulizing tube 10 are fixedly connected inside the T-shaped tube 4, a piston plate 11 is slidably connected inside the T-shaped tube 4, a guide tube 12 is inserted through the inside of the piston plate 11, a stabilizing ring 13 and a limiting ring 14 are fixedly installed inside the T-shaped tube 4, a spring 15 is fixedly connected to the outer wall of the piston plate 11, a connecting plate 16 is fixedly installed inside the guide tube 12, a sealing plate 17 is integrally formed on the outer side of the connecting plate 16, and an oxygen tube 18 is inserted through the inside of the top cover 1.

[0027] Specifically, when using this device, the flow meter 3 is connected to the hospital bedside equipment belt. When the patient needs oxygen supply, such as... Figure 1 As shown, moving the horizontal bar 5 to the left causes the two connecting cavities 8 to move, as... Figure 5 The position shown is moved to the right, and the connecting cavity 8 on the left side of the crossbar 5 coincides with the guide tube 12. At this time, the flow meter 3 supplies oxygen, and the pressure inside the T-tube 4 increases. Under the principle of atmospheric pressure, this drives the piston plate 11 to move, causing the guide tube 12 inside the piston plate 11 to insert into the connecting cavity 8. At this point, the crossbar 5 will be unable to move. Figure 5As shown, the left connecting cavity 8 is connected to the humidification tube 9, and then oxygen enters the humidification bottle 2. The humidified oxygen is discharged through the oxygen tube 18 to achieve the effect of discharging the humidified oxygen. The oxygen tube 18 is used to connect oxygen masks and other oxygen supply equipment to achieve the effect of supplying oxygen. When the oxygen supply is stopped, the oxygen pressure inside the T-tube 4 decreases. Under the action of the second spring 15, the piston plate 11 and the guide tube 12 will move out of the connecting cavity 8. At this time, the crossbar 5 is no longer restricted and will be reset under the action of the first spring 7 to prepare for the next oxygen supply or nebulization.

[0028] When a patient needs nebulization, such as Figure 1 As shown, moving the horizontal bar 5 to the right causes the connecting cavity 8 to move to the right. If the viewpoint is changed, as... Figure 5 As shown, the horizontal bar 5 will move to the left, so that the connecting cavity 8 is connected to the guide tube 12. At this time, oxygen will be discharged through the nebulizer tube 10. The nebulizer tube 10 can be connected to the nebulizer device, and then the patient will be nebulized.

[0029] To prevent oxygen leakage and cross-contamination, the sealing rings restrict the oxygen supplied by the guide tube 12 to between the two sealing rings, such as... Figure 4 As shown, when the connecting cavity 8 moves, the blockage will seal off the pipe on the other side, for example: Figure 5 As shown, when the horizontal bar 5 moves to the right, it moves the left connecting cavity 8, which in turn connects the blockage on the right side with the atomizing tube 10, thus sealing the atomizing tube 10 and preventing oxygen leakage. Pushing the horizontal bar 5 in the opposite direction can cause the blockage to seal the humidification tube 9 on the left side, which can also prevent oxygen leakage. Therefore, there will be no oxygen leakage.

[0030] In the embodiment: two communicating cavities 8 are symmetrically arranged inside the crossbar 5, and two springs 7 are fixedly connected to both ends of the crossbar 5;

[0031] Specifically, the connecting cavity 8 is symmetrically arranged inside the crossbar 5 to connect the two different atomizing tubes 10 and humidifying tubes 9, which can realize the function of changing the direction of oxygen. The spring 7 is fixedly connected to both ends of the crossbar 5, which can drive the crossbar 5 to reset, thus realizing the effect of resetting the crossbar 5.

[0032] In the embodiment: the outer wall of the stabilizing ring 13 is fixedly connected to the second spring 15, and the second spring 15 is disposed on the inner side of the limiting ring 14;

[0033] Specifically, the stabilizing ring 13 is fixedly connected to the second spring 15 to achieve the effect of stabilizing and supporting the stabilizing ring 13. The second spring 15 is set inside the limiting ring 14, which does not affect the compression of the second spring 15, and can achieve the effect of stabilizing the movement of the guide tube 12.

[0034] In the embodiment: the outer wall of the sealing plate 17 is movably connected to the interior of the guide tube 12, and the guide tube 12 is adapted to the interior of the two communicating cavities 8;

[0035] Specifically, the outer wall of the sealing plate 17 is movably connected to the inside of the guide tube 12, which can achieve the effect of sealing the guide tube 12. The guide tube 12 is adapted to the connecting cavity 8 to achieve the effect of inserting the guide tube 12 into the connecting cavity 8.

[0036] In the embodiment: two sealing rings are provided between the crossbar 5 and the T-tube 4, and the two sealing rings are symmetrically arranged on the inner side of the T-tube 4. Two plugs are fixedly installed on the outer wall of the crossbar 5, and the two plugs are arranged on the inner side of the two communicating cavities 8.

[0037] Specifically, two sealing rings are provided between the crossbar 5 and the T-tube 4. The sealing rings are used to isolate oxygen, and the plug is used to seal the connecting cavity 8 to prevent oxygen leakage.

[0038] In this embodiment: a sealing gasket is provided at the front end of the guide tube 12, and the sealing gasket is movably connected to the outer wall of the crossbar 5;

[0039] Specifically, a sealing gasket is provided at the front end of the guide tube 12. The sealing gasket is used to seal and block oxygen, thus preventing oxygen leakage.

[0040] Working principle: The flow meter 3 is connected to the hospital bedside equipment belt. When the patient needs oxygen supply, the horizontal bar 5 moves to the left, causing the two connecting chambers 8 to move. The flow meter 3 supplies oxygen, increasing the pressure inside the T-tube 4, which in turn moves the piston plate 11. This causes the guide tube 12 inside the piston plate 11 to insert into the connecting chamber 8. At this point, the horizontal bar 5 cannot move, and oxygen enters the humidification bottle 2. The humidified oxygen is then discharged through the oxygen supply tube 18, achieving the effect of discharging humidified oxygen. When the oxygen supply stops, the oxygen pressure inside the T-tube 4 decreases, and under the action of the spring 15, the flow meter 3 will stop supplying oxygen. The piston plate 11 and guide tube 12 are moved out of the communicating cavity 8. At this time, the crossbar 5 is no longer restricted and will be reset under the action of the spring 7, preparing for the next oxygen supply or nebulization. Compared with related technologies, the ward humidification bottle 2 control valve reset device provided by this utility model has the following beneficial effects: It solves the problem that the existing humidification bottle 2 control valve does not have a reset function. After the humidification bottle 2 is used up, the valve will not automatically reset. If another port needs to be used next time, oxygen may leak due to the valve not being reset, which may cause safety hazards.
