Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to an oxygen humidifying bottle with a ratchet locking structure. Background Art

[0002] An oxygen humidifying bottle is a device in medical equipment used to humidify oxygen when a patient undergoes oxygen therapy. Its main function is to increase the humidity of the inhaled oxygen to prevent damage to the respiratory mucosa of the patient due to dryness and help maintain the normal physiological functions of the respiratory tract. During the process of the ambulance traveling to the location of the patient, medical staff will make preliminary preparations for the required medical devices to ensure that corresponding operations can be performed on the patient in the shortest time. When supplying oxygen to the patient, a disposable oxygen humidifying bottle is usually selected.

[0003] Existing disposable oxygen humidifying bottles usually set a screw cap at the oxygen inlet to isolate the connection state between the oxygen humidifying bottle and the outside world, preventing external bacteria, dust, etc. from entering the humidifying liquid, and thus preventing the patient from being infected during the oxygen inhalation process. When medical staff are making preparations on the ambulance, they will wear medical gloves to prevent the instruments from being contaminated by bacteria on their hands. At this time, when the medical staff open, connect, and install the oxygen humidifying bottle, due to the vehicle bumping and the medical gloves they wear, they cannot quickly rotate the screw cap and connect the oxygen supply pipeline to the oxygen inlet. When the oxygen supply pipeline slips during the installation process to the oxygen inlet due to the above problems, it will even cause the oxygen humidifying bottle to be unusable. Summary of the Invention

[0004] The purpose of the present invention is to provide an oxygen humidifying bottle with a ratchet locking structure to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An oxygen humidifying bottle with a ratchet locking structure, including a bottle body and a top cover. The top cover is fixedly connected to the top opening of the bottle body. An oxygen inlet is provided on the top surface of the top cover. A ventilation pipe is slidably sleeved inside the oxygen inlet. A vertical sliding groove is provided on the side wall of the oxygen inlet. A vertical sliding block is fixedly connected to the outer side surface of the ventilation pipe. The vertical sliding block is slidably connected inside the vertical sliding groove. A ratchet rack is fixedly embedded on the outer side surface of the vertical sliding block. A horizontal sliding groove is provided on the side surface of the vertical sliding groove. The teeth of the ratchet rack face the horizontal sliding groove. A tooth block is slidably connected inside the horizontal sliding groove. Compressed air is filled inside the horizontal sliding groove to push the tooth block towards the ratchet rack.

[0006] It further includes a sealing mechanism. The sealing mechanism includes a raised cavity provided near the bottom end of the ventilation pipe and a sealing plug fixedly connected to the inner bottom surface of the bottle body. The sealing mechanism isolates the inside and outside of the bottle body from the bottom end of the ventilation pipe.

[0007] Preferably, a sealing ring is fixedly sleeved on the top of the closing plug, and an annular sealing groove is formed in the inner wall of the ventilation pipe, and the sealing groove is located between the bottom end of the ventilation pipe and the convex cavity.

[0008] Preferably, the sealing ring is made of an elastic material and is in interference fit with the sealing groove. When the ventilation pipe is in an open state, the sealing ring disengages from the sealing groove and is located in the convex cavity.

[0009] Preferably, an annular plate is fixedly sleeved on the outer side of the ventilation pipe near the top end, and a spring is elastically connected between the bottom surface of the annular plate and the top surface of the top cover.

[0010] Preferably, a plurality of ventilation grooves are formed in the side surface of the closing plug, and the length of the ventilation grooves is greater than the distance from the convex cavity to the bottom end of the ventilation pipe.

[0011] Preferably, a humidifier is fixedly sleeved on the ventilation pipe, and the humidifier is located outside the convex cavity.

[0012] Preferably, an oxygen supply pipe joint is slidably sleeved inside the oxygen inlet, and the oxygen supply pipe joint is in interference fit with the oxygen inlet.

[0013] Preferably, an oxygen outlet is formed in the side surface of the top cover, and a plurality of convex blocks are fixedly connected to the outer side surface of the oxygen supply pipe joint.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When the present invention is not in use, it is in a closed state. At this time, the sealing ring on the closing plug is embedded in the sealing groove, thereby closing the bottom end of the ventilation pipe. At this time, external air cannot enter the humidifying liquid in the bottle body through the top of the ventilation pipe, so there is no need to set a sealing cover on the ventilation pipe, thereby reducing the generation of plastic waste. At the same time, the operation steps of medical staff for installing the oxygen humidifying bottle are reduced, and the preparation efficiency of medical staff is improved. Secondly, through the set closing mechanism, when the device needs to be connected to an oxygen supply device, only by pushing the oxygen supply pipe joint downward, at this time, after the oxygen supply pipe joint contacts the annular plate and pushes the annular plate downward, the entire ventilation pipe is driven to move downward. At this time, due to the movement of the ventilation pipe, the sealing ring disengages from the sealing groove, and at the same time, a part of the ventilation groove enters the convex cavity, so that the oxygen provided by the oxygen supply device enters from the top of the ventilation pipe and enters the bottle body through the ventilation groove. The above steps enable the present invention to be removed and recycled even when it is installed on a fixed bracket, as long as the oxygen supply pipe joint is not actually pushed to connect the inside of the bottle body with the external air, thereby reducing waste generated in cases such as accidental opening and being used as a spare.

[0016] 2. When the ventilation pipe of the present invention is pushed downward by the oxygen supply pipe joint, the ratchet rack embedded in the vertical slider moves downward accordingly. At this time, as the ratchet rack moves downward, the teeth of the ratchet rack push the tooth block to move into the horizontal sliding groove, and the compressed air in the horizontal sliding groove is further compressed. As the ventilation pipe stops moving, the ratchet rack stops moving. At this time, the compressed air in the horizontal sliding groove expands, thereby pushing the tooth block to move in the direction of the ratchet rack. At this time, the front end of the tooth block is embedded in the teeth of the ratchet rack, so that the ratchet rack cannot move upward, and then the vertical slider cannot move upward, avoiding that when installing the oxygen supply pipe joint, the spring pushes the annular plate upward, causing the ventilation pipe to move upward again, resulting in the bottom of the ventilation pipe being re-closed.

[0017] 3. Finally, the spring in the present invention serves to offset part of the downward pressure received by the ventilation pipe, thereby avoiding that during storage, transportation and other links, the ventilation pipe gradually slides downward due to vibration and other reasons, resulting in the ventilation pipe being in an open state when not in use, and the humidifying liquid in the bottle body being contaminated, causing waste of the oxygen humidifying bottle.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] As Figures 1 to 8 shown, the embodiment of the present invention provides an oxygen humidifying bottle with a ratchet locking structure, which includes a bottle body 1 and a top cover 2. The top cover 2 is fixedly connected to the top opening of the bottle body 1. An oxygen inlet 3 is provided on the top surface of the top cover 2. A ventilation pipe 5 is slidably sleeved inside the oxygen inlet 3. A vertical chute 16 is provided on the side wall of the oxygen inlet 3. A vertical slider 14 is fixedly connected to the outer side surface of the ventilation pipe 5. The vertical slider 14 is slidably connected in the vertical chute 16. A ratchet rack 15 is fixedly embedded on the outer side surface of the vertical slider 14. A horizontal chute 17 is provided on the side surface of the vertical chute 16. The teeth of the ratchet rack 15 face the horizontal chute 17. A tooth block 18 is slidably connected in the horizontal chute 17. Compressed air is filled in the horizontal chute 17 to push the tooth block 18 to move towards the ratchet rack 15;

[0029] It further includes a sealing mechanism. The sealing mechanism includes a convex cavity 6 provided near the bottom end of the ventilation pipe 5 and a sealing plug 7 fixedly connected to the inner bottom surface of the bottle body 1. The sealing mechanism isolates the inside and outside of the bottle body 1 from the bottom end of the ventilation pipe 5.

[0030] When the present invention is not in use, it is in a closed state. At this time, the sealing ring 8 on the sealing plug 7 is embedded in the sealing groove 9, thereby closing the bottom end of the ventilation pipe 5. At this time, external air cannot enter the humidifying liquid in the bottle body 1 through the top of the ventilation pipe 5. Therefore, there is no need to set a sealing cover on the ventilation pipe 5, thereby reducing the generation of plastic waste. At the same time, the operation steps of medical staff for installing the oxygen humidifying bottle are reduced, and the preparation efficiency of medical staff is improved. Secondly, through the provided sealing mechanism, when the device needs to be connected to an oxygen supply device, only by pushing the oxygen supply pipe joint 19 downward, at this time, after the oxygen supply pipe joint 19 contacts the annular plate 12, it pushes the annular plate 12 to move downward, and then drives the entire ventilation pipe 5 to move downward. At this time, due to the movement of the ventilation pipe 5, the sealing ring 8 disengages from the sealing groove 9, and at the same time, a part of the ventilation groove 10 enters the convex cavity 6, so that the oxygen provided by the oxygen supply device enters from the top of the ventilation pipe 5 and enters the bottle body 1 through the ventilation groove 10. The above steps enable the present invention to be removed and recycled as long as the oxygen supply pipe joint 19 is not actually pushed to connect the inside of the bottle body 1 with the outside air even if it is installed on a fixed bracket, thereby reducing waste generated in cases such as accidental opening and being used as a spare.

[0031] When the vent pipe 5 of the present invention is pushed downward by the oxygen supply pipe joint 19, the ratchet rack 15 embedded in the vertical slider 14 moves downward together. At this time, as the ratchet rack 15 moves downward, the teeth of the ratchet rack 15 push the tooth block 18 to move into the horizontal chute 17, and the compressed air in the horizontal chute 17 is further compressed. As the vent pipe 5 stops moving, the ratchet rack 15 stops moving. At this time, the compressed air in the horizontal chute 17 expands, thereby pushing the tooth block 18 to move in the direction of the ratchet rack 15. At this time, the front end of the tooth block 18 is embedded in the teeth of the ratchet rack 15, so that the ratchet rack 15 cannot move upward, and further the vertical slider 14 cannot move upward, avoiding that when installing the oxygen supply pipe joint 19, the spring 13 pushes the annular plate 12 upward, causing the vent pipe 5 to move upward again, resulting in the bottom of the vent pipe 5 being re-closed.

[0032] Finally, the spring 13 in the present invention plays a role in offsetting part of the downward pressure received by the vent pipe 5, thereby avoiding that during storage, transportation and other links, the vent pipe 5 gradually slides downward due to vibration and other reasons, resulting in the vent pipe 5 being in an open state when not in use, and the humidifying liquid in the bottle body 1 being contaminated, causing waste of the oxygen humidifying bottle.

[0033] As Figure 5 shown, a sealing ring 8 is fixedly sleeved on the top of the closing plug 7, and an annular sealing groove 9 is formed on the inner wall of the vent pipe 5. The sealing groove 9 is located between the bottom end of the vent pipe 5 and the convex cavity 6. The sealing ring 8 is made of an elastic material and is in interference fit with the sealing groove 9. When the vent pipe 5 is in an open state, the sealing ring 8 is disengaged from the sealing groove 9 and is located in the convex cavity 6.

[0034] When the sealing ring 8 is embedded in the sealing groove 9, since the sealing ring 8 is made of an elastic material and is in interference fit with the sealing groove 9, the sealing ring 8 will block the gap between the closing plug 7 and the vent pipe 5, thereby avoiding the entry of external air into the bottle body 1 in the closed state, and at the same time avoiding the inflow of the humidifying liquid in the bottle body 1 into the inside of the vent pipe 5, preventing the humidifying liquid in the bottle body 1 from being contaminated. As the vent pipe 5 is pushed downward and moves, the sealing ring 8 is disengaged from the sealing groove 9. At this time, the air pressure provided by the oxygen injected from the oxygen inlet 3 will push the humidifying liquid to be introduced into the vent pipe 5 into the bottle body 1, avoiding the contact between the humidifying liquid and the inner wall of the vent pipe 5, thereby avoiding the contamination of the humidifying liquid by the sundries attached to the inner wall of the vent pipe 5.

[0035] As Figures 2 to 8 shown, an annular plate 12 is fixedly sleeved on the outer side surface of the vent pipe 5 near the top end. A spring 13 is elastically connected between the bottom surface of the annular plate 12 and the top surface of the top cover 2. The annular plate 12 is located in the oxygen inlet 3 and is in interference fit with the oxygen inlet 3.

[0036] The annular plate 12 is first arranged to contact the oxygen supply pipe joint 19, so as to drive the ventilation pipe 5 to move together when the oxygen supply pipe joint 19 is pushed. Secondly, it also enables the spring 13 to push the ventilation pipe 5 upward. Then, when the ventilation pipe 5 is pushed by a force smaller than a certain magnitude, the spring 13 can offset the thrust, thus preventing the closing mechanism from being accidentally triggered and opened due to vibration or other reasons, and preventing the humidifying liquid in the bottle body 1 from being contaminated. Finally, due to the blockage of the annular plate 12, external air cannot enter the bottle body 1 through the outside of the ventilation pipe 5, also avoiding the humidifying liquid from being contaminated by the outside world, ensuring that patients inhale clean oxygen.

[0037] As Figure 5 shown, a plurality of ventilation grooves 10 are formed on the side surface of the closing plug 7, and the length of the ventilation grooves 10 is greater than the distance from the convex cavity 6 to the bottom end of the ventilation pipe 5.

[0038] When the bottom end of the ventilation pipe 5 is closed by the closing mechanism, the sealing ring 8 is embedded in the sealing groove 9. At this time, the part of the ventilation groove 10 that does not enter the convex cavity 6, and external air cannot enter the bottle body 1 through the ventilation groove 10, avoiding the contamination of the humidifying liquid in the bottle body 1. As the ventilation pipe 5 is pushed downward, a part of the ventilation groove 10 enters the convex cavity 6, enabling the externally input oxygen to enter the humidifying liquid along the ventilation groove 10 and be humidified, so that the closing device can be opened simply by pressing down, improving the simplicity of use.

[0039] As Figures 1 to 8 shown, a humidifier 11 is fixedly sleeved on the ventilation pipe 5. The humidifier 11 is located outside the convex cavity 6. An oxygen supply pipe joint 19 is slidably sleeved inside the oxygen inlet 3. The oxygen supply pipe joint 19 is in interference fit with the oxygen inlet 3. An oxygen outlet 4 is formed on the side surface of the top cover 2. A plurality of convex blocks 20 are fixedly connected to the outer side surface of the oxygen supply pipe joint 19.

[0040] Working principle:

[0041] When using the present invention, first fix the bottle body 1 on the bracket for installing a disposable oxygen humidifying bottle, then connect the oxygen supply pipe joint 19 with the oxygen supply device, and then insert the oxygen supply pipe joint 19 between the oxygen inlet 3 and the ventilation pipe 5. When in use, push the oxygen supply pipe joint 19 downward. At this time, the oxygen supply pipe joint 19 pushes the annular plate 12 downward, and the annular plate 12 pushes the ventilation pipe 5 downward, so that the sealing ring 8 disengages from the sealing groove 9. At this time, a part of the ventilation groove 10 on the side surface of the closing plug 7 enters the convex cavity 6, so that the inside of the ventilation pipe 5 is communicated with the inside of the bottle body 1. At this time, the oxygen entering from the oxygen inlet 3 enters the bottle body 1 and is humidified.

[0042] When the oxygen supply pipe joint 19 is pushed downward to drive the annular plate 12 and the ventilation pipe 5 to move downward, as the ventilation pipe 5 moves, the ratchet rack 15 moves downward together with the ventilation pipe 5. When the front end of the ratchet rack 15 contacts the front end of the tooth block 18, it will push the tooth block 18 to slide into the horizontal chute 17, thereby compressing the air in the horizontal chute 17. As the ventilation pipe 5 stops moving, the compressed air expands at this time, thereby pushing the tooth block 18 to move outward, and then the front end of the tooth block 18 is embedded into the ratchet rack 15, and then the ventilation pipe 5 cannot move upward, thus avoiding the interruption of oxygen supply caused by the upward movement of the ventilation pipe 5 during the oxygen supply process.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
